En overal is oorlog. Sommige mensen doen op kleine of grotere schaal concreet hun best om het beter te maken. https://berthub.eu/articles/posts/hellend-vlak-sidn-europa/ Fri, 09 Feb 2024 15:15:21 +0100 https://berthub.eu/articles/posts/hellend-vlak-sidn-europa/ Door Corinne CathDr. Corinne Cath is an anthropologist of technology who studies the politics of Internet infrastructure.

Redactie Daniël Mol. In deze aflevering bespreken we hoe het zo gekomen is met Europa’s bedroevende positie in de cloud, maar ook hoe onze overheden door zelf verstandiger in te kopen een grote rol zouden kunnen hebben in het (her)opwekken van onze cloudindustrie. https://berthub.eu/articles/posts/volkskrant-columns/ Sat, 03 Feb 2024 11:51:50 +0100 https://berthub.eu/articles/posts/volkskrant-columns/ In november 2023 was ik de gast-columnist van de Volkskrant, en heb ik vier stukjes geschreven die steeds op zondag (alleen online) verschenen. Dit was voor mij voor het eerst dat ik echt iedere week moest ’leveren’, en ook nog binnen heldere kaders: 700 woorden, opinie over dingen die al in het nieuws geweest zijn. Ik heb nu een nieuw respect voor de columnisten die zoiets iedere week weer kunnen, en tegelijk zie ik ook dat niet iedereen wekelijks een topprestatie kan leveren. https://berthub.eu/articles/posts/volkskrant-kamerleden/ Sat, 03 Feb 2024 11:21:50 +0100 https://berthub.eu/articles/posts/volkskrant-kamerleden/ Iets eerdere versie van het stuk in de Volkskrant, deel van een serie van vier columns: Het ligt niet aan de Kamerleden Het is verkiezingstijd, en het is bon ton om te klagen over het gebrek aan ervaring van Kamerleden, en om vervolgens ook nog te constateren dat juist de meest ervaren parlementariërs niet terugkeren na de verkiezingen. En dat is ook schrijnend, en ook ik heb er schande van gesproken. https://berthub.eu/articles/posts/volkskrant-afluister-privacy-wet/ Sat, 03 Feb 2024 11:21:50 +0100 https://berthub.eu/articles/posts/volkskrant-afluister-privacy-wet/ Iets eerdere versie van het stuk in de Volkskrant, deel van een serie van vier columns: Ze zeiden het echt. De geheime diensten AIVD en MIVD krijgen binnenkort een nieuwe wet waarmee ze makkelijker en vaker kunnen afluisteren en hacken. Vorige week legden ze het voorstel uit in de Eerste Kamer, en claimden daar dat hun nieuwe wet eigenlijk een privacywet is (!). Nou wist ik al dat het niet best gesteld was met ons besef van privacy, maar dit is toch wel heel Orwelliaans. https://berthub.eu/articles/posts/volkskrant-wen-er-maar-aan-klimaatgesleutel/ Sat, 03 Feb 2024 11:21:50 +0100 https://berthub.eu/articles/posts/volkskrant-wen-er-maar-aan-klimaatgesleutel/ Iets eerdere versie van het stuk in de Volkskrant, deel van een serie van vier columns: De wereld gaat de klimaatdoelen niet halen (volgens de Verenigde Naties). Hoewel er in Nederland harder wordt gewerkt aan CO₂-reductie dan menigeen denkt gaat het niet genoeg zijn. Ook zijn veel van de lokale resultaten het gevolg van de-industrialisatie, waarbij productie hier verdwijnt en verhuist naar omgevingen met minder regels en goedkopere stroom. Het ziet er dus niet goed uit. https://berthub.eu/articles/posts/volkskrant-leiders-met-kennis-van-zaken/ Sat, 03 Feb 2024 11:05:31 +0200 https://berthub.eu/articles/posts/volkskrant-leiders-met-kennis-van-zaken/ Iets eerdere versie van het stuk in de Volkskrant, deel van een serie van vier columns: Leiders? Ik weet niet hoe het met u zit, maar op de werkvloer heb ik me zelden ‘geleid’ gevoeld. Wel gemanaged. En hoewel ook belangrijk, is dat toch echt iets heel anders. Iemand een leider noemen doen we hier niet snel, het klinkt zelfs raar. “Only sheep need a leader”. Toch is het in Amerika een veel alledaagser begrip, en houdt de vice-president conferenties waar “our future leadership” wordt aangemoedigd. https://berthub.eu/articles/posts/a-2024-plea-for-lean-software/ Thu, 18 Jan 2024 10:22:53 +0100 https://berthub.eu/articles/posts/a-2024-plea-for-lean-software/ This post is dedicated to the memory of Niklaus Wirth, a computing pioneer who passed away January 1st. In 1995 he wrote an influential article called “A Plea for Lean Software”, and in what follows, I try to make the same case nearly 30 years later, updated for today’s computing horrors. The really short version: the way we build/ship software these days is mostly ridiculous, leading to 350MB packages that draw graphs, and simple products importing 1600 dependencies of unknown provenance. https://berthub.eu/articles/trifecta/ Thu, 18 Jan 2024 10:22:53 +0100 https://berthub.eu/articles/trifecta/ Trifecta is actual stand-alone software that you can use to paste and drag images to, for easy sharing. It has pained me for years that I had to use imgur for this purpose. Not only does imgur install lots of cookies and trackers on my browser, I also then force these onto the people that visit the images that I share. I checked out some existing solutions you could download, but I worry about their security. https://berthub.eu/articles/posts/trifecta-technology/ Thu, 18 Jan 2024 10:22:53 +0100 https://berthub.eu/articles/posts/trifecta-technology/ Trifecta is a simple open source image sharing site, built with a combination of modern C++, database and web technologies. Intended to both be useful and make some points. This page sets out to explain the underlying technology of this small yet hopefully useful piece of software. More background can be found on its main page, where you can also read a bit about why I built this software. In short, 1: I need an image sharing site I trust and that does not track its users and 2: I want to show that you can still run a service yourself safely. https://berthub.eu/articles/posts/european-innovation-and-capabilities/ Thu, 11 Jan 2024 10:57:50 +0200 https://berthub.eu/articles/posts/european-innovation-and-capabilities/ Over the past few years I’ve been writing a lot about innovation, and specifically, the lack thereof in Europe. I also touch on how we’ve outsourced a ton of operational capabilities, leaving us relatively helpless. By now this is such a huge amount of words, audio and video that it is in dire need of a summary, if only to see if it makes any kind of sense taken together. https://berthub.eu/articles/posts/taking-the-airbus-to-the-ikea-cloud/ Thu, 11 Jan 2024 09:27:14 +0100 https://berthub.eu/articles/posts/taking-the-airbus-to-the-ikea-cloud/ This article is part of a series on (European) innovation and capabilities. The very short version: All of computing is moving to the cloud at a rapid pace, including (government) parts you might want to keep under your own control Europe has no relevant ‘hyperscaler’ cloud providers at all, and there is a desire to change this by policy means Competing with the IKEA-concept is nearly impossible. Offering IKEA-like products but then with a smaller range is not an attractive proposition. https://berthub.eu/articles/posts/het-curieuze-artikel-73-aivd-mivd/ Mon, 08 Jan 2024 19:15:03 +0100 https://berthub.eu/articles/posts/het-curieuze-artikel-73-aivd-mivd/ Vandaag groot in het nieuws, een Nederlandse AIVD agent zou een sleutelrol gespeeld hebben in het binnenbrengen van sabotagesoftware bij het Iraanse kernwapenprogramma. Nou moet me wel van het hart, dit zou op zichzelf geen schandaal moeten zijn. Iran zijn onze vrienden niet, en ik heb liever dat ze geen kernwapenprogramma hebben. Wel wekken de artikelen van Huib Modderkolk in de Volkskrant de indruk dat politiek Den Haag niet of niet voldoende op de hoogte was van dit alles. https://berthub.eu/articles/posts/eu-cra-what-does-it-mean-for-open-source/ Sat, 30 Dec 2023 10:56:56 +0100 https://berthub.eu/articles/posts/eu-cra-what-does-it-mean-for-open-source/ The final compromise text of the EU Cyber Resilience Act is now officially available, and various open source voices are currently opining on it. This is a complex act and other parts of the open source world (like the Eclipse Foundation and NLNet Labs) have been hard at work to advocate with the EU and member states to get a CRA that is good for open source. I’ve also been highly critical. https://berthub.eu/articles/posts/eu-cra-recitals-comments-compiler-judge/ Fri, 29 Dec 2023 19:56:56 +0100 https://berthub.eu/articles/posts/eu-cra-recitals-comments-compiler-judge/ A bit of an “emergency blog post”. The final compromise text of the EU Cyber Resilience Act is now available, and various open source voices are now opining on it. This is a complex act and other parts of the open source world (like the Eclipse Foundation and NLNet Labs) have been hard at work to advocate with the EU and member states to get a CRA that is good for open source. https://berthub.eu/articles/posts/de-mottekasteel-debating-truc/ Fri, 22 Dec 2023 13:34:18 +0200 https://berthub.eu/articles/posts/de-mottekasteel-debating-truc/ Je kunt een discussie winnen op de vorm of op de inhoud. Ik heb het graag over de inhoud, maar dan moet je wel goed opletten dat je ook echt aan die inhoud toekomt. Want er zijn genoeg mensen die het liever over wat anders hebben, of het houden bij mooie woorden die niet de kern van hun mening of plan zijn. Men noemt dat soort technieken ook wel “debating trucjes”. https://berthub.eu/articles/posts/eu-cra-best-open-source-security/ Sun, 12 Nov 2023 14:22:46 +0100 https://berthub.eu/articles/posts/eu-cra-best-open-source-security/ UPDATE: On December 1st the EU agreed on a version of the Cyber Resilience Act that appears to have substantially addressed the concerns in the post below. Further analysis awaits, but do know that the text that follows is now mostly of historical interest! UPDATE 2: Here is the final compromise text of the Cyber Resilience Act. UPDATE 3: Here is an analysis of what it means for open source. https://berthub.eu/articles/posts/verslag-wetgevingsoverleg-nieuwe-aivd-mivd-wet/ Tue, 17 Oct 2023 12:50:40 +0200 https://berthub.eu/articles/posts/verslag-wetgevingsoverleg-nieuwe-aivd-mivd-wet/ Hieronder een licht bewerkte versie van mijn live-verslag op Mastodon van het wetgevingsoverleg over de nieuwe AIVD/MIVD wet. De tijdstippen voor iedere regel linken naar de uitstekende Debat Gemist service van de Tweede Kamer. Het tijdstip is steeds 60 seconden voor de update, dus misschien moet je nog verder terug in de tijd om bij de corresponderende beelden te komen. Het verslag is live ingetypt, en vermeldt ook wat persoonlijke meningen. https://berthub.eu/articles/posts/prop-sub-csam/ Sat, 14 Oct 2023 10:21:10 +0200 https://berthub.eu/articles/posts/prop-sub-csam/ Dit artikel is geschreven naar aanleiding van het recente rondetafelgesprek in de Tweede Kamer over het EU client side scanning voorstel, ook bekend als ‘chatcontrol’, een verplichte module in je WhatsApp/Signal/iMessage/Snapchat die je communicatie en foto’s scant op ‘grooming’ en bekende en onbekende kinderporno & automatisch melding doet bij politie en Europol. Meer achtergrond is hier te vinden. Specifiek onderwerp van dit stuk is de proportionaliteit van de voorgenomen regelgeving. https://berthub.eu/articles/posts/client-side-scanning-dutch-parliament/ Thu, 12 Oct 2023 12:21:10 +0200 https://berthub.eu/articles/posts/client-side-scanning-dutch-parliament/ On the 11th of October, Dutch parliament organized a hearing on the EU “Chatcontrol” proposal, with a focus on client side scanning. Dutch parliament had earlier passed two motions calling on the Dutch government not to support this proposal, but our government has declared it will ignore those motions. This hearing was timely because next week, or even this Friday, EU member states vote on how to proceed with this terrible proposal (Lawfare review from a US perspective). https://berthub.eu/articles/posts/rondetafel-11-oktober-chatcontrol/ Thu, 12 Oct 2023 10:21:10 +0200 https://berthub.eu/articles/posts/rondetafel-11-oktober-chatcontrol/ Op 11 oktober was er een rondetafelgesprek in de Tweede Kamer over het EU ‘Chatcontrol’ voorstel. Hier is mijn position paper voor dat gesprek te vinden. Die pagina heeft ook links naar de artikelen in NRC, BNR, NOS en de uitzending van het NOS journaal. Hieronder het transcript van mijn opmerkingen. Op de site van de Tweede Kamer is het origineel met beeld en geluid te vinden. Tekst: Dit onderwerp ben ik al zo’n jaar of 15 af en aan bij betrokken. https://berthub.eu/articles/posts/client-side-scanning/ Sun, 08 Oct 2023 10:21:10 +0200 https://berthub.eu/articles/posts/client-side-scanning/ Dit is mijn position paper voor het rondetafelgesprek in de Tweede Kamer op 11 oktober over het EU client side scanning voorstel, ook bekend als ‘chatcontrol’, een verplichte module in je WhatsApp/Signal/iMessage/Snapchat die je communicatie en foto’s scant op ‘grooming’ en bekende en onbekende kinderporno & automatisch melding doet bij politie en Europol. UPDATE: De opname van het rondetafelgesprek staat nu online - mijn stukje begint om 19:19 maar ook de rest is de moeite waard (transcript, voor wie niet van filmpjes houdt). https://berthub.eu/articles/posts/niks-te-verbergen-wel-steeds-meer-uit-te-leggen/ Wed, 27 Sep 2023 10:55:31 +0200 https://berthub.eu/articles/posts/niks-te-verbergen-wel-steeds-meer-uit-te-leggen/ Onze overheden en het internationale bedrijfsleven leggen steeds grotere databases over ons aan, op een schaal die we 20 jaar geleden nooit geaccepteerd zouden hebben. Eerder schreef ik in de Volkskrant hoe we dit vroeger automatisch verwerpelijk vonden, met name vanwege onze herinnering aan de Tweede Wereldoorlog. Update: We bespraken dit artikel in de BNR Nexus podcast van 29 september (vanaf minuut 24). Deze herinnering leeft minder en minder, en ook “Oost-Duitsland” en de Stasi zijn verdwenen en geen afschrikwekkend voorbeeld meer. https://berthub.eu/articles/posts/co2-global-warming-sensitivity/ Mon, 25 Sep 2023 10:21:10 +0200 https://berthub.eu/articles/posts/co2-global-warming-sensitivity/ Before we start, I’d like to thank ESA’s Mark McCaughrean who helped kick off this article by referring me to two key articles that lay out, in scientific terms, how global warming really works. Here you can pick your favorite temperature unit: C F (Test temperature: ) Feel free to skip this wordy intro and head straight to the model, or even to the summary at the end of this post! https://berthub.eu/articles/posts/nluug-award/ Sat, 23 Sep 2023 10:13:15 +0200 https://berthub.eu/articles/posts/nluug-award/ I won an award! Earlier this year I was lured to the NLUUG spring conference, and after my presentation (on machine learning from scratch), the two large presentation rooms were joined for some additional announcements. Turns out this was to give me an NLUUG Lifetime Achievement Award! Previous awardees include Piet Beertema, Guido van Rossum, Wietse Venema, Bram Moolenaar, Andy Tanenbaum, Wytze van der Raay, Teus Hagen, Michiel Leenaars, Olaf Kolkman and these are all awesome people who made massive contributions to the world and the Internet. https://berthub.eu/articles/posts/denken-en-voelen/ Sat, 16 Sep 2023 13:46:04 +0200 https://berthub.eu/articles/posts/denken-en-voelen/ Tussen de enorme blogposts van 6000 woorden over het klimaat, hier wat luchtige observaties over denken, voelen en wetgeving. Denken en voelen zijn twee wegen om tot beslissingen te komen. Beide zijn waardevol. We hoeven maar te horen van een situatie en we hebben er al gevoelens over, nog voor er veel feiten in beeld zijn.

Ik schreef hier eerder uitgebreid over, en ik sprak er (samen met vele anderen) ook over in een rondetafel gesprek in de Tweede Kamer (video, spreektekst met voetnoten). https://berthub.eu/articles/posts/a-bit-on-absorption-and-spectra/ Tue, 29 Aug 2023 10:21:10 +0200 https://berthub.eu/articles/posts/a-bit-on-absorption-and-spectra/ This is a companion page to my blog post on global warming (which is currently not yet ready). I put up this post already as a teaser for my upcoming global warming post, which desperately needs expert review before I dare put it online. If you are an experienced climate/atmospheric scientist, would you please consider helping me out? Please email me on bert@hubertnet.nl if you can spare the time to skim my work for gross errors. https://berthub.eu/articles/posts/on-climate-change-and-management/ Fri, 28 Jul 2023 10:21:10 +0200 https://berthub.eu/articles/posts/on-climate-change-and-management/ Nothing on this page is factually controversial. However, many things in this post make for uncomfortable reading. And, climate discourse is now so politicized that many factual statements are taken as dog whistles. For example, in what follows I will state that climate has always been changing, and has in fact never been stable for very long. This is 100% true, but people interpret this as if the writer means that our current climate change is not caused by human beings, or is nothing to worry about. https://berthub.eu/articles/posts/on-being-useful/ Sat, 01 Jul 2023 09:03:58 +0200 https://berthub.eu/articles/posts/on-being-useful/ I wrote this piece after an early-career friend of mine asked some very good questions on how to be useful. Since this is a thing I struggle a bit with myself, I thought it worthwhile to write up my thoughts. Note that I fully understand that not everyone has the luxury to think about their career like this – you first have to take care of yourself and family before you can start fretting about if your working life is saving the world! https://berthub.eu/articles/posts/dutch-postcode-and-building-database/ Wed, 21 Jun 2023 10:20:43 +0200 https://berthub.eu/articles/posts/dutch-postcode-and-building-database/ Recently, I wrote a small open source tool to make the official Dutch national address & building database more accessible. More about the tool below, but first an introduction. Last data update: 2024-02-09 If all you need is an up to date CSV file of all Dutch addresses, their zipcodes and coordinates, scroll down to the end. If all you need is a web service, try https://berthub.eu/pcode/2513AA/14.

Sinds een tijdje maak ik grafiekjes van hoe Nederland aan z’n elektriciteit komt. En soms ben ik daar dan enthousiast over, zeker als de wind waait en de zon goed schijnt. https://berthub.eu/articles/posts/dutch-intel-law-about-intel/ Wed, 07 Jun 2023 20:10:43 +0200 https://berthub.eu/articles/posts/dutch-intel-law-about-intel/ This is a mirror of the original about:intel post, since the about:intel server is sadly sometimes overloaded. Also do read the opposing view from Jan-Jaap Oerlemans and the reflection by Lotte Houwing The Dutch government is proposing adding a lex specialis to its existing intelligence and security services act. This addition significantly changes the scope of many powers and also extends who they can be applied to. A draft of an English summary of this proposed law can be found here. https://berthub.eu/articles/posts/reflectie-rondetafelgesprek-cyberwet/ Thu, 06 Apr 2023 13:07:36 +0200 https://berthub.eu/articles/posts/reflectie-rondetafelgesprek-cyberwet/ Gisteren (5 april) was er een technische briefing van de AIVD en MIVD over de tijdelijke wet cyberoperaties, gevolgd door een rondetafelgesprek met deskundigen. Vorige week was er een technische briefing door de toezichthouders TIB en CTIVD. Mijn spreektekst met veel klikbare voetnoten ter verduidelijking staat hier. Er was een goeie opkomst van geïnteresseerden en Kamerleden, en er waren goede en goed geïnformeerde vragen. Verder schreven de media over de bijeenkomsten: De Correspondent, NRC, Trouw, AD, GeenStijl https://berthub.eu/articles/posts/ki-umwaelzung-fuer-die-wirtschaft-garantiert/ Mon, 03 Apr 2023 14:25:07 +0200 https://berthub.eu/articles/posts/ki-umwaelzung-fuer-die-wirtschaft-garantiert/ Vielen Dank an Lili Laguna für diese Übersetzung diesen niederländischen Blog-Beitrag. English version. Jeder überschlägt sich mit Vorhersagen über KI. Sie wird uns von stupider Arbeit befreien, sie wird unsere Bildung zerstören, wir alle werden nichts mehr lernen müssen, weil die KI es für uns tun wird, Kriminelle werden uns mit ihr austricksen, Gauner werden mit ihr unendliche Mengen an Desinformation erzeugen, und die KI wird entkommen und in der realen Welt gefährlich werden. https://berthub.eu/articles/posts/ai-is-guaranteed-to-disrupt-us/ Sat, 01 Apr 2023 15:50:00 +0200 https://berthub.eu/articles/posts/ai-is-guaranteed-to-disrupt-us/ This is a machine-aided translation of this Dutch post. Und jetzt auch auf Deutsch verfügbar! Everyone is tumbling over themselves making predictions about AI. It’s going to free us from menial work, it’s going to dismantle our education, we all won’t have to learn things anymore because the AI will do it for us, criminals will trick us with it, crooks will create endless amounts of disinformation with language models, and the AI will escape and become dangerous in the real world. https://berthub.eu/articles/posts/ai-sowieso-ontwrichtend/ Fri, 31 Mar 2023 10:50:00 +0200 https://berthub.eu/articles/posts/ai-sowieso-ontwrichtend/ Update: This article is now also available in English. Und jetzt auch auf Deutsch! Iedereen buitelt over zichzelf heen om voorspellingen te doen over AI. Het gaat ons bevrijden van dom werk, het gaat ons onderwijs ontmantelen, we hoeven allemaal dingen niet meer te leren want de AI gaat het voor ons doen, criminelen zullen ons er mee bedonderen, boeven gaan er eindeloze hoeveelheden desinformatie mee maken, en de AI zal ontsnappen en in de echte wereld gevaarlijk worden. https://berthub.eu/articles/posts/dl-and-now-what/ Thu, 30 Mar 2023 12:00:09 +0200 https://berthub.eu/articles/posts/dl-and-now-what/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! After having completed this series of blogposts (well done!) you should have a good grounding in what deep learning is actually doing. However, this was of course only a small 20k word introduction, so there is a lot left to learn. Unfortunately, there is a lot of nonsense online. https://berthub.eu/articles/posts/dl-ocr-demo/ Thu, 30 Mar 2023 12:00:08 +0200 https://berthub.eu/articles/posts/dl-ocr-demo/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! The previous chapters have often mentioned the chasm between “deep learning models that work on my data” and “it actually works in the real world”. It is perhaps for this reason that almost all demos and YouTube tutorials you find online never do any real world testing. https://berthub.eu/articles/posts/dropout-data-augmentation-weight-decay/ Thu, 30 Mar 2023 12:00:07 +0200 https://berthub.eu/articles/posts/dropout-data-augmentation-weight-decay/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! In the previous chapter we found ways to speed up our character recognition learning by a factor of 20 by using a better optimizer, and a further factor of four by cleverly using threads using a ‘shared nothing architecture’. We also learned how we can observe the development of parameters. https://berthub.eu/articles/posts/hyperparameters-inspection-adam/ Thu, 30 Mar 2023 12:00:06 +0200 https://berthub.eu/articles/posts/hyperparameters-inspection-adam/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! In the previous chapter we successfully trained a network to recognize handwritten letters, but it took an awfully long time. This is not just inconvenient: networks that take too long to train mean we can experiment less. Some things really are out of reach if each iteration takes 24 hours, instead of 15 minutes. https://berthub.eu/articles/posts/dl-convolutional/ Thu, 30 Mar 2023 12:00:05 +0200 https://berthub.eu/articles/posts/dl-convolutional/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! In the previous chapter we taught a network of linear combinations and ‘rectified linear units’ to recognize handwritten digits reasonably successfully. But we already noted that the network would be sensitive to the exact location of pixels, and that it does not in any meaningful way “know” what a 7 looks like. https://berthub.eu/articles/posts/handwritten-digits-sgd-batches/ Thu, 30 Mar 2023 12:00:04 +0200 https://berthub.eu/articles/posts/handwritten-digits-sgd-batches/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! In the previous chapter we described how automatic differentiation of the result of neural networks works. In the first and second chapters we designed and trained a one-layer neural network that could distinguish images of the digit 3 and the digit 7, and the network did so very well. https://berthub.eu/articles/posts/autograd/ Thu, 30 Mar 2023 12:00:03 +0200 https://berthub.eu/articles/posts/autograd/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! In the previous chapter we configured a neural network and made it learn to distinguish between the digits 3 and 7. The learning turned out to consist of “twisting the knobs in the right direction”. Although simplistic, the results were pretty impressive. But, you might still be a bit underwhelmed - the network only distinguished between two digits. https://berthub.eu/articles/posts/first-learning/ Thu, 30 Mar 2023 12:00:02 +0200 https://berthub.eu/articles/posts/first-learning/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! In this chapter we’re going to take the neural network we made earlier, but actually make it do some learning itself. And, oddly enough, this demonstration will again likely simultaneously make you wonder “is this all??” and also impress you by what even this trivial stuff can do. https://berthub.eu/articles/posts/hello-deep-learning-chapter1/ Thu, 30 Mar 2023 12:00:01 +0200 https://berthub.eu/articles/posts/hello-deep-learning-chapter1/ This page is part of the Hello Deep Learning series of blog posts. You are very welcome to improve this page via GitHub! In this chapter we’re going to build our first neural network and take it for a spin. Weirdly, this demonstration will likely simultaneously make you wonder “is this all??” and also impress you by what even this trivial stuff can do. The first part of this chapter covers the theory, and shows no code. https://berthub.eu/articles/posts/hello-deep-learning-intro/ Thu, 30 Mar 2023 12:00:00 +0200 https://berthub.eu/articles/posts/hello-deep-learning-intro/ This page is part of the Hello Deep Learning series of blog posts. Also, feel free to skip this intro and head straight for chapter 1 where the machine learning begins! Deep learning and ‘generative AI’ have now truly arrived. If this is a good thing very much remains to be seen. What is certain however is that these technologies will have a huge impact. Up to late 2022, I had unwisely derided the advances of deep learning as overhyped nonsense from people doing fake demos. https://berthub.eu/articles/posts/hello-deep-learning/ Thu, 30 Mar 2023 11:59:00 +0200 https://berthub.eu/articles/posts/hello-deep-learning/ A from scratch GPU-free introduction to modern machine learning. Many tutorials exist already of course, but this one aims to really explain what is going on, from the ground up. Also, we’ll develop the demo until it is actually useful on real life data which you can supply yourself. Other documents start out from the (very impressive) PyTorch environment, or they attempt to math it up from first principles. Trying to understand deep learning via PyTorch is like trying to learn aerodynamics from flying an Airbus A380. https://berthub.eu/articles/posts/eu-cra-practicalities/ Thu, 23 Mar 2023 16:51:39 +0100 https://berthub.eu/articles/posts/eu-cra-practicalities/ This is a living document - I’d normally spend a few days polishing everything, but since CRA talks are ongoing right now, there’s simply no time for that. Check back frequently for updates! Also please let me know urgently on bert@hubertnet.nl if you think I’m reading things incorrectly! As a follow-up to my earlier post on the EU Cyber Resilience Act, here I’d like to address some practicalities: how would it actually work. https://berthub.eu/articles/posts/eu-cra-secure-coding-solution/ Tue, 14 Mar 2023 09:13:10 +0100 https://berthub.eu/articles/posts/eu-cra-secure-coding-solution/ First a round of thanks for the many people in industry and government who provided valuable links, background and insights! I could not have done this without your help! If you spot any mistakes, or have suggestions, please do contact me on bert@hubertnet.nl The EU’s new Cyber Resilience Act is admirable in its goal. And the EU is not alone in thinking something needs to be done about the dreadful state of security online – the Biden administration has just released its National Cybersecurity Strategy that has similar aims. https://berthub.eu/articles/posts/asimov-on-creativity/ Mon, 13 Mar 2023 09:13:10 +0100 https://berthub.eu/articles/posts/asimov-on-creativity/ “The history of human thought would make it seem that there is difficulty in thinking of an idea even when all the facts are on the table” – Isaac Asimov In 2014, MIT’s Technology Review wrote a very interesting article about an attempt to have Isaac Asimov be part of a group of scientists attempting to think outside of the box. In this article they included a 1959 essay that Asimov wrote instead of continuing to taking part in this (classified) government work. https://berthub.eu/articles/posts/reactie-consultatie-nota-van-wijziging-tijdelijke-cyberwet/ Sun, 15 Jan 2023 14:49:33 +0100 https://berthub.eu/articles/posts/reactie-consultatie-nota-van-wijziging-tijdelijke-cyberwet/ Deze reactie is als PDF ook te vinden op de site internetconsultatie.nl.

Je elektriciteitsrekening bestaat (volgens de regels geldend op op 2 januari 2023) dan uit de volgende componenten: De kale kWh-prijs die je energieleverancier verzonnen heeft (waarover later meer, per kWh) Opslag Duurzame Energie- en Klimaattransitie (ODE) (3,05 cent per kWh in 2022, 0 cent in 2023) Energiebelasting (3,679 cent per kWh, 12,599 cent per kWh in 2023) BTW over al het bovenstaande (9% laatste helft 2022, per 1 januari 2023 weer 21%) Dit samen is wat je elektriciteitsbedrijf hun “tarief per kWh inclusief belastingen” moet noemen. https://berthub.eu/articles/posts/always-do-this-floating-point/ Sat, 24 Dec 2022 21:28:43 +0100 https://berthub.eu/articles/posts/always-do-this-floating-point/ This is a refreshed & expanded copy of a very old page I hosted outside of this blog. I recently ran into “silent NaNs” again, and thought it might be a good idea to republish this advice here. A small post that documents something that almost no one appears to know.

Hier een versie met klikbare links ter onderbouwing: Recent presenteerde het kabinet een nieuwe wet die volgens de Autoriteit Persoonsgegevens inhoudt dat alle banktransacties van alle Nederlandse rekeninghouders gemonitord zullen worden in één gecentraliseerde database, met gebruik van algoritmes. De uitvoering zal in handen komen van een commerciële derde partij. Dit alles ter voorkoming van witwassen en terrorismefinanciering.

Feedback is very welcome on bert@hubertnet.nl. I’d also like to thank the many proofreaders, but all mistakes remain mine! In the world of (high) technology, Europe is exceptionally weak at innovating. There are many ways to explain how this came to be, and a lot of the discussion focuses on unfair business conditions and regulation. In this post however I want to talk about important cultural and social reasons that are at least part of the reason, and present some possible solutions. https://berthub.eu/articles/posts/uitleg-over-de-wiv-2/ Fri, 02 Dec 2022 09:00:01 +0200 https://berthub.eu/articles/posts/uitleg-over-de-wiv-2/ UPDATE: Nu ik niet meer werk voor de TIB kan deze uitleg van de nieuwe wet weer online. Via dit artikel zijn interviews en podcasts te vinden met meer context. UPDATE: Het rondetafelgesprek op 5 april 2023 in de Tweede Kamer is hier te bekijken en hier te lezen. En hier mijn spreektekst met voetnoten. Het kabinet heeft een wetsvoorstel gepubliceerd wat het toezicht en de bevoegdheden van de inlichtingen- en veiligheidsdiensten ingrijpend verandert. https://berthub.eu/articles/posts/the-world-of-yesterday/ Sat, 26 Nov 2022 13:47:37 +0100 https://berthub.eu/articles/posts/the-world-of-yesterday/ A brief review of Stefan Zweig’s 1942 book “Die Welt von Gestern: Erinnerungen eines Europäers”, which I read in the earlier English translation by Benjamin W. Huebsch and Helmut Ripperger (public domain copy). There is also a more recent translation by Anthea Bell, The World of Yesterday: Memoirs of a European. It too appears to be excellent.   It is not often that one feels the urge to review an 80 year old work, but it left such a huge impression on me that I simply must tell you about what I’ve just read. https://berthub.eu/articles/posts/bonds-and-the-ten-year-interest-rate/ Mon, 31 Oct 2022 13:29:37 +0100 https://berthub.eu/articles/posts/bonds-and-the-ten-year-interest-rate/ So in these wild times, the “ten year interest rate” is suddenly in the news again. But what does this mean? There is no committee that sets these rates, but it is also not something you can just measure. While you’ll find various other explanations of how to calculate the 10 year interest rate online, this may be the geekiest one, and definitely is the only one with a built-in calculator. https://berthub.eu/articles/posts/big-data-storage/ Fri, 21 Oct 2022 19:33:51 +0200 https://berthub.eu/articles/posts/big-data-storage/ This is a page about some of the mechanics of ‘big data’, specifically how to store, transfer and process perhaps 100s of millions or billions of rows/events. Although some people think big data starts at 65k rows, at which point Excel used to lose it, I’m talking about gigabytes of data here. Infrastructure for this kind of thing abounds. Data can however come from lots of sources, and go to lots of different places. https://berthub.eu/articles/posts/resignation-as-intelligence-regulator/ Fri, 09 Sep 2022 10:55:00 +0200 https://berthub.eu/articles/posts/resignation-as-intelligence-regulator/ I’ve seen some mediocre automated translations of my Dutch language resignation statement go round. To prevent any confusion, please find the story here in English: Until today I was one of the three members of the board that checks warrants for the Dutch intelligence and security services. This board is called “Toetsingscommissie Inzet Bevoegdheden” or TIB. If either of the civil or the military intelligence and security services of The Netherlands want to use their lawful intercept, SIGINT or hacking (& some other) legal powers, they have to first convince their own jurists, then their ministry and finally the TIB. https://berthub.eu/articles/posts/vertrek-tib/ Fri, 09 Sep 2022 10:55:00 +0200 https://berthub.eu/articles/posts/vertrek-tib/ Vandaag was mijn laatste dag als lid van de Toetsingscommissie Inzet Bevoegdheden Inlichtingen- en Veiligheidsdiensten (TIB), de commissie die vooraf bindend toetst of de voorgenomen inzet van de zwaarste bevoegdheden van de AIVD en MIVD rechtmatig is. Update: Onderaan dit artikel staat een uitgebreid media overzicht De reden voor dit vertrek is mijn zorg over de “Tijdelijke wet onderzoeken AIVD en MIVD naar landen met een offensief cyberprogramma” (samenvatting), die tot doel heeft het toezicht vooraf te beperken, het toezicht vooraf op de technische risico’s af te schaffen en die aanvullend een forse verruiming van de bevoegdheden van de diensten inhoudt. https://berthub.eu/articles/posts/uitleg-over-de-wiv-1/ Fri, 09 Sep 2022 09:16:22 +0100 https://berthub.eu/articles/posts/uitleg-over-de-wiv-1/ Recent is er een nieuw wetsvoorstel gepresenteerd bedoeld om de AIVD en de militaire MIVD meer ruimte te geven om onderzoek te doen naar landen met een offensief cyberprogramma. Op deze pagina bespreek ik de zwaarste bevoegdheden die de diensten hebben om hun werk te doen. De Wet op de Inlichtingen- en Veiligheidsdiensten 2017 (‘Wiv’) is een moderne wet die de Nederlandse inlichtingen- en veiligheidsdiensten, als het noodzakelijk is, juridisch toestemming geeft alles af te luisteren, te hacken of te laten kopiëren, waar ook ter wereld. https://berthub.eu/articles/posts/improved-galileo-fix-time/ Wed, 07 Sep 2022 12:47:39 +0200 https://berthub.eu/articles/posts/improved-galileo-fix-time/ In the world of Global Navigation Satellite Systems (GNSS), change tends to happen very slowly and cautiously. It is therefore quite exciting how many new features Galileo, the “European GPS” has been rolling out lately. Earlier I wrote a little bit about the High Accuracy Service (HAS), whereby the Galileo satellites themselves provide properly equipped receivers (not your phone) with near-realtime updates that can be used to achieve very good accuracy. https://berthub.eu/articles/posts/tracker-beeper/ Mon, 29 Aug 2022 10:45:14 +0200 https://berthub.eu/articles/posts/tracker-beeper/ A week ago, I finally got round to implementing an idea I’d been toying with for years: what if your computer made a little bit of noise every time it sent data to Google? From studying logs, I’d long known just how many sites send all your visits and clicks to (at least) Google, but a log that you have to manually create first and then analyze is not very dramatic. https://berthub.eu/articles/posts/mch-dna-and-gps-gnss-talks/ Wed, 27 Jul 2022 13:41:11 +0200 https://berthub.eu/articles/posts/mch-dna-and-gps-gnss-talks/ (scroll down for my two talks if you are in a hurry) As I write this I’m suffering from severe post-camp blues. Every four years the Dutch hacker community organizes a stupendously large multi-day campsite event, with ample international help. To a large extent, “everyone” is there. And this time, like every time, people who originally decided they could not make it.. show up by day two. Because the pull is just too strong. https://berthub.eu/articles/posts/nerdfluisteraar/ Sat, 04 Jun 2022 21:05:40 +0200 https://berthub.eu/articles/posts/nerdfluisteraar/ Eerder dit jaar spraken Kustaw Bessems en ik elkaar in een aflevering van de Volkskrant podcast ‘Stuurloos’ (reservelink). In een uitzending van meer dan een uur behandelden we waarom het zo moeilijk is voor de overheid en grote bedrijven om mensen te werven die ergens echt veel vanaf weten, en die mensen vervolgens ook te behouden. Ik had me gemeld bij ‘Stuurloos’ na het beluisteren van de zeer waardevolle eerdere aflevering Gevaarlijke combinatie: politici én ambtenaren zonder vakkennis met Geert-Jan Hamilton en Peter van Lieshout (artikel). https://berthub.eu/articles/posts/cyber-energy-law-and-policy/ Wed, 25 May 2022 10:46:46 +0200 https://berthub.eu/articles/posts/cyber-energy-law-and-policy/ As presented on the 24th of May 2022 at the European Energy Law Seminar 2022 organized by the Dutch Energy Law Association (NeVER), in cooperation with the University of Groningen’s Centre of Energy Law and Sustainability and the University of Oslo’s Scandinavian Institute of Maritime Law So before we delve into the fascinating relation between cybersecurity and the worlds of oil, gas, energy and electricity, I need to introduce myself a bit. https://berthub.eu/articles/posts/looking-for-an-editor/ Fri, 15 Apr 2022 10:55:06 +0200 https://berthub.eu/articles/posts/looking-for-an-editor/ Hi everyone, A brief note, I’ve written a book, and the content is nearly done. You can read all about it here. The first 90% of the project went well, but I need (well paid) help with the remaining 90% to turn it into a decent book. This is a ‘for profit’ book, but it will be given away for free to schools, universities and readers/students unable to afford it. So there is a bit of feel-good factor involved. https://berthub.eu/articles/posts/dutch-electrical-power-figures-2/ Thu, 14 Apr 2022 21:44:21 +0200 https://berthub.eu/articles/posts/dutch-electrical-power-figures-2/ In an earlier post I presented a naive model for estimating Dutch electrical solar power generation numbers. It turns out that the Dutch electrical power generation numbers are an even bigger mess than I appreciated. It appears that “everyone knows” that the numbers are confusing, incomplete and perhaps even wrong. But somehow this state of confusion isn’t written down anywhere. So I’ll give it a shot. A round of thanks to a small number of anonymous industry insiders that provided invaluable help! https://berthub.eu/articles/bio/ Thu, 14 Apr 2022 12:22:53 +0200 https://berthub.eu/articles/bio/ I prefer not to spend too much time talking about myself, but I also like to make it clear who I am and what I do, so people don’t have to guess (because they might guess wrong). I studied physics at Delft University of Technology, but dropped out somewhere around 40%. I still love physics though. Until recently I was a part time ex-ante regulator of the Dutch intelligence and security services. https://berthub.eu/articles/posts/dutch-electrical-power-figures-and-solar-model/ Sun, 27 Mar 2022 10:47:53 +0200 https://berthub.eu/articles/posts/dutch-electrical-power-figures-and-solar-model/ As part of my coping mechanisms, I like to make graphs of important things I worry about. Recently with the Russia-inflicted horrors in Ukraine, I’ve been looking at the torrent of Russian gas being bought by Europe. This turned into a live plot that shows just how much money we are sending to Russia. In that post, I also dwell on how we are using that gas to heat our houses and generate electricity. https://berthub.eu/articles/posts/about-that-russian-gas/ Mon, 21 Mar 2022 08:46:24 +0100 https://berthub.eu/articles/posts/about-that-russian-gas/ The horrors of the Russian war on Ukraine continue unabated. Every eurocent we send to Russia is an intolerable assault on the senses. The world buys lots of things from Russia. For some of these, if Europe does not buy them, someone else will. But there is one major exception: natural gas. Over the past few weeks I’ve been automating graphs that show, on an hourly basis, just how much gas we buy from Russia: https://berthub.eu/articles/posts/some-academic-business-advice/ Thu, 03 Feb 2022 10:27:25 +0100 https://berthub.eu/articles/posts/some-academic-business-advice/ So I love academia, and I also built two businesses. When I dropped out of studying physics to focus on my company, I assumed I knew everything, since I had studied physics! Turned out that if you enter the world of commerce, it is very bad if you are visibly confused about the difference between business development and sales. It does nothing for your credibility. People in enterprise will likely and correctly conclude that you know nothing about running companies if you are hazy on concepts that are fundamental to them. https://berthub.eu/articles/posts/a-science-experiment-got-published/ Tue, 25 Jan 2022 14:50:28 +0200 https://berthub.eu/articles/posts/a-science-experiment-got-published/ And we’re back! As noted in part 1 and part 2 I thought it might be possible that I had discovered something interesting in biology. Lacking an academic peer group, I had decided to use a series of blog posts to gather feedback and to keep myself honest. I’m very pleased to report that this process worked! I just received word that Nature Scientific Data has formally accepted my paper “SkewDB, a comprehensive database of GC and 10 other skews for over 30,000 chromosomes and plasmids” for publication! https://berthub.eu/articles/posts/simple-parallelism-idiom/ Tue, 18 Jan 2022 11:52:00 +0100 https://berthub.eu/articles/posts/simple-parallelism-idiom/ If you programmed something and it turns out to be too slow, often you’d like to farm out the work to multiple threads. At this point you typically have a few choices: use some kind of producer/consumer pipe half-ass it by dividing the work into n chunks and launch n threads and hope for the best rely on one of the magic parallelization solutions (#pragma omp) use (newfangled) language features All of these options are painful to some extent. https://berthub.eu/articles/posts/corona-ooit-houdt-het-op/ Tue, 23 Nov 2021 08:30:46 +0100 https://berthub.eu/articles/posts/corona-ooit-houdt-het-op/ Na mijn vorige deprimerende stukje over ons stompzinnige Coronabeleid gooi ik het nu over een wat positievere boeg. Want het lijkt er soms wel op alsof er geen enkele vooruitgang geboekt is, en we hier nooit meer uit gaan komen, maar dat is echt niet zo. Foto van Ivan Diaz op Unsplash Om met het begin te beginnen, de coronacijfers zijn hoger dan we ooit gemeten hebben (al waren ze in werkelijkheid in maart 2020 vermoedelijk nog hoger). https://berthub.eu/articles/posts/het-onuitstaanbare-corona-beleid/ Sat, 20 Nov 2021 10:45:16 +0100 https://berthub.eu/articles/posts/het-onuitstaanbare-corona-beleid/ Echt, ik trek het niet meer. Regeren is vooruitzien. Ik denk dat we dus niet regeren in Nederland. Corona is, ook na twee jaar, nog steeds een ontwikkelend ding. Het virus, de vaccins, de reacties van mensen, ze blijven ons verbazen. Maar een ding is inmiddels wel constant: geïnformeerde mensen in de buitenwereld zien maanden van tevoren ontwikkelingen aankomen die daarna tot het uiterste genegeerd worden door onze politieke leiders. https://berthub.eu/articles/posts/who-controls-the-internet/ Tue, 02 Nov 2021 15:02:51 +0100 https://berthub.eu/articles/posts/who-controls-the-internet/ This is a lightly edited transcript of my keynote over at NANOG 83, so please accept my apologies if some of the wording is not (yet) as clear as it should be! The original video, including Q&A can be found on NANOG’s Youtube channel Hello, and welcome to this presentation on who controls the internet, and if they actually should. As you can see, I cover all grounds here. All kinds of flags are in this presentation and all kinds of companies. https://berthub.eu/articles/posts/personeelsbehoud/ Mon, 25 Oct 2021 09:44:26 +0200 https://berthub.eu/articles/posts/personeelsbehoud/ Ik schreef er eerder over, hoe werf je nieuwe collega’s. Het stuk is weer actueel nu het zo moeilijk is om aan personeel te komen, of om mensen zelfs maar te behouden. Medisch personeel verlaat de werkvloer – (C) Luis Melendez Sinds 1999 neem ik mensen aan of hielp ik bij werving, voor de overheid, mijn voormalige bedrijven & die van anderen, maar ook voor scholen en instellingen. Ik heb er dus wel een beetje kijk op. https://berthub.eu/articles/posts/corona-update-oktober-2021/ Sat, 23 Oct 2021 11:48:23 +0200 https://berthub.eu/articles/posts/corona-update-oktober-2021/ Het heeft even geduurd, maar er is weer een Coronaupdate. Wederom dank aan iedereen die met vragen kwam. Hoe gaat het nu? Ik durf het niet te zeggen. In veel landen gaan de cijfers omhoog. In de UK zijn ze al tijden en tijden torenhoog. De vaccins houden goed stand tegen ernstige ziekte (zie verderop). Maar of de cijfers nog veel verder omhoog zullen gaan, ik durf het niet te zeggen. https://berthub.eu/articles/skewdb/ Fri, 17 Sep 2021 12:22:53 +0200 https://berthub.eu/articles/skewdb/ The Scientific Spring Meeting KNVM & NVMM 2022 presentation is here (pdf).

SkewDB, a comprehensive database of GC and 10 other skews for over 30,000 chromosomes and plasmids, Nature Scientific Data, 2022 doi:10.5061/dryad.g4f4qrfr6 Last database update: 20th of November 2022, now featuring homopolymer counts & codon bias data! Welcome to SkewDB! A free database of GC and many other skews for over 36,300 chromosomes and plasmids (viewer, blog post). https://berthub.eu/articles/posts/skewdb-an-open-database-of-gc-and-other-microbial-skews/ Mon, 30 Aug 2021 14:19:18 +0200 https://berthub.eu/articles/posts/skewdb-an-open-database-of-gc-and-other-microbial-skews/ Hello and welcome to this introduction of the SkewDB. This open (downloadable) database contains details of GC skew, plus a dozen other skews, for all 28,000 bacterial chromosomes available through the NCBI genomes service. The database is created using the open source Antonie DNA software. There is also an online viewer that includes graphs. GC skew is the phenomenon where almost all circular chromosomes tend to have near equal amounts of G and C nucleotides, per strand, but where the leading replication strand contains an excess of G, and the lagging replication strand has an excess of C nucleotides. https://berthub.eu/articles/posts/a-science-experiment-part-2/ Thu, 26 Aug 2021 14:50:28 +0200 https://berthub.eu/articles/posts/a-science-experiment-part-2/ And we’re back! As noted in part 1, there is the possibility I’ve discovered something interesting in biology. Lacking an academic peer group, I’m using a series of blog posts to gather feedback and to keep myself honest. Because chances continue to be high that as an outsider I am deluding myself. The full backstory can be found in part 1 without which this installment will not make much sense. https://berthub.eu/articles/posts/a-science-experiment/ Thu, 19 Aug 2021 09:27:09 +0200 https://berthub.eu/articles/posts/a-science-experiment/ So, I think I may have discovered something interesting in biology! Professional scientists know this feeling all too well. Exhilarated that it looks like you might be the first person ever to know something, but worried sick that it might not be real. Also, you might be fooling yourself – and you are the easiest person to fool. And even if it is real, does it even mean something? Or did you effectively discover that hot things are not cold? https://berthub.eu/articles/posts/kpn-interactieve-tv-zelf-doen/ Thu, 12 Aug 2021 16:36:42 +0200 https://berthub.eu/articles/posts/kpn-interactieve-tv-zelf-doen/ Ik ben een heel tevreden klant van KPN Internet. Om diverse redenen gebruik ik de Experia Box niet, maar ik wil wel graag TV kunnen kijken met de KPN Interactieve TV Set Top Box. Vroeger ging dat “vanzelf goed”, tegenwoordig is daar wat werk voor nodig. In augustus 2021 werkten deze instructies goed, maar er kunnen dingen veranderen bij KPN natuurlijk!

Earlier this year I was very happy to be interviewed by Thomas Ramge for Germany’s Federal Agency for Disruptive Innovation (SPRIND). Many podcasts are just two guys talking to each other, but here Thomas brought along a lot of expertise & spent serious time preparing, which contributed hugely to having a productive conversation.

Een belangrijk onderwerp, maar ook een onderwerp waarover een hoop zomaar geroepen wordt. Veel artsen en beleidsmakers zien een foto van dikke mensen en roepen “Zucht, leefstijl”. En dan vraag ik me weleens af, hebben jullie ook maar één te dikke vriend of vriendin met wie jullie hier weleens over praten? Want zolang we elkaar niet begrijpen is er een groot probleem. https://berthub.eu/articles/posts/demystifying-european-digital-sovereignty/ Tue, 13 Jul 2021 21:15:30 +0200 https://berthub.eu/articles/posts/demystifying-european-digital-sovereignty/ This article is part of a series on (European) innovation and capabilities. Recently I participated in a very useful panel that aimed to demystify European digital sovereignty. Even though we spoke for more than an hour (video), we obviously were not able to fix all of Europe’s sovereignty problems! The event was organized by Scaleway (previously Online SAS or Online.net), a 100% subsidiary of what I think is Europe’s most innovative telecommunications company, Iliad. https://berthub.eu/articles/posts/corona-newsflash/ Mon, 05 Jul 2021 21:30:13 +0200 https://berthub.eu/articles/posts/corona-newsflash/ Een extra update, twee weken na de vorige, want er is al weer voldoende te vertellen. Deze keer weer een aantal vragen op verzoek: De cijfers stijgen ineens heel hard, wat betekent dat? Is het veilig om naar evenementen te gaan? Zou mijn dochter/zoon zich moeten laten vaccineren? Werken de vaccins nog wel? Wat de f is er aan de hand met de cijfers ineens Goeie vraag. Ze gaan omhoog en hard ook. https://berthub.eu/articles/posts/eneco-moet-dit-nou/ Fri, 02 Jul 2021 20:45:37 +0200 https://berthub.eu/articles/posts/eneco-moet-dit-nou/ UPDATE: Zoals gezegd had ik Eneco om een reactie gevraagd en die is gekomen. In het kort, Eneco vertelt me dat de website een onjuiste weergave van zaken gaf. De teksten zullen aangepast worden. Het niet instemmen met ieder kwartier meten & analyse van gebruik zal geen effect hebben op het automatisch doorgeven van meterstanden voor de rekening en het online overzicht. Wel is het dan zo dat de Eneco App minder inzicht kan verschaffen zonder ieder kwartier verse data, maar dat is natuurlijk niet anders. https://berthub.eu/articles/posts/tracking-free-audience-statistics/ Sun, 27 Jun 2021 13:46:27 +0200 https://berthub.eu/articles/posts/tracking-free-audience-statistics/ As regular readers of this blog will know, I am no friend of the surveillance capitalism that currently powers the web. It is becoming well-neigh impossible to develop any software or host any content without some component tracking your users & sending data to third parties. Even though I try very hard not to fall for this, periodically I discover that my sites also embed things that embed things that potentially leak your details to third parties. https://berthub.eu/articles/posts/corona-delta-update/ Tue, 22 Jun 2021 09:00:45 +0200 https://berthub.eu/articles/posts/corona-delta-update/ In de vorige Corona update eind mei schreef ik over “delta”, toen nog bekend als de Indiase variant: Het is helaas te vroeg om nu een eindoordeel te vellen over deze variant. Wat we wel weten is dat in de UK de vaccins prima standhouden - de overgrote meerderheid van de mensen in het ziekenhuis is ongevaccineerd. Dit is nog steeds waar. Toch weten we nu een stuk meer. https://berthub.eu/articles/posts/help-my-sin-is-slow-and-my-fpu-is-inaccurate/ Sat, 19 Jun 2021 14:53:25 +0200 https://berthub.eu/articles/posts/help-my-sin-is-slow-and-my-fpu-is-inaccurate/ Afer 8 years, I have updated this this post for 2021-era Linux (and also to fix bitrotted links). I am extremely joyful to report that the (hard) problem from 2013 appears to have been solved! There is a small addendum at the end to reflect this happy news. Back in 2013, I started writing code to do a simulation of biological system, and I got stuck after 20 lines. My test code tried to go through a million time steps doing basically nothing, and it was taking a minute to do it. https://berthub.eu/articles/posts/europes-software-problem/ Tue, 15 Jun 2021 09:56:07 +0200 https://berthub.eu/articles/posts/europes-software-problem/ This article is part of a series on (European) innovation and capabilities. Europe’s communication needs are currently almost exclusively delivered by Chinese hardware that connects us to US-based platforms. For a variety of reasons, this is not a good idea. As stated recently by Charles Michel, President of the European Council, “Interdependence is natural, even desirable. Over-dependence, however, is not”. Photo by Sara Kurfeß on Unsplash At the core, the problem is that almost no consumer-oriented platforms or software products are being created in Europe, or more precisely, by European companies. https://berthub.eu/articles/posts/recensie-een-spoor-van-vernieuwing-arthur-docters-van-leeuwen/ Mon, 14 Jun 2021 08:47:36 +0200 https://berthub.eu/articles/posts/recensie-een-spoor-van-vernieuwing-arthur-docters-van-leeuwen/ Reeds vorig jaar verschenen, maar zonder de aandacht gekregen te hebben die dit boek verdient. Uitgeverij Prometheus, 460 pagina’s. bol.com, amazon.nl & kindle “Een spoor van vernieuwing” laat zich lezen als memoires van een markante topambtenaar, maar ook als een interessante geschiedenis van de ontwikkeling van de rampenbestrijding, de inrichting van de politie en de opsporing, de BVD (voorloper AIVD) en de oprichting en ontwikkeling van wat we nu kennen als de AFM. https://berthub.eu/articles/posts/reed-solomon-for-programmers/ Sun, 13 Jun 2021 06:38:15 +0200 https://berthub.eu/articles/posts/reed-solomon-for-programmers/ Recently I was doing some work decoding the new Galileo High Accuracy Service data. In short, this new service will allow Galileo (“European GPS”) users to achieve decimeter-level accuracy, which is nice. This “HAS” data is transmitted highly redundantly by making good use of Reed-Solomon encoding. To work with this data, I attempted to learn more about Reed-Solomon and I found almost all explanations were useless to me - oodles of advanced math, but no guidance of how to use R-S in practice. https://berthub.eu/articles/posts/corona-update-eind-mei-2021/ Mon, 24 May 2021 14:16:45 +0200 https://berthub.eu/articles/posts/corona-update-eind-mei-2021/ Ja daar zijn we weer! De vorige update uit maart was getiteld “Licht aan het einde van de tunnel”. Nou wil ik niet al te veel pochen, en resultaten uit het verleden bieden geen garanties voor de toekomst, maar het klopte allemaal best behoorlijk. De spectaculaire daling in ziekenhuiscijfers kwam in werkelijkheid een week later dan ik verwacht had. Ok. Ik wil graag mijn Facebook- en IRC-vrienden bedanken voor hun vele goede vragen en suggesties voor deze post - want er zijn nog genoeg goede vragen over. https://berthub.eu/articles/posts/corona-und-dein-onkel/ Sun, 23 May 2021 20:48:24 +0200 https://berthub.eu/articles/posts/corona-und-dein-onkel/ Wir haben Coronamaßnahmen, aber Menschen weigern sich, mitzuhelfen. Es gibt effektive Impfungen, aber Menschen verkünden laut, diese niemals nehmen zu wollen. In diesem Text bringe ich einige Vorschläge, wie du einen wichtigen Beitrag zur Aufklärung der Menschen leisten kannst. Ja, genau du. Viele Leser meines Blogs sind die “Haustechniker” in der Verwandtschaft, die das WLAN einrichten, den Fernseher aufbauen oder schwierige Dinge erklären. Gute Aussichten, als jemand gesehen zu werden, den man um Rat fragen kann und der sich auskennt. https://berthub.eu/articles/posts/favorite-recipes/ Sun, 23 May 2021 11:50:58 +0200 https://berthub.eu/articles/posts/favorite-recipes/ This page is nothing special, I put recipes there I look up from time to time on the monstrous ad-laden recipe sites that also tell me your life story. I use cups because they aren’t the worst. Dutch Baby First: Heat cast iron pan, heat oven to 220C. Ingredients: 3 large eggs 1/2 cup of full fat milk 1/2 cup of flour tablespoon of sugar / vanilla sugar 4 tablespoons of butter More butter for preparation Whisk first four ingredients together, while melting the butter. https://berthub.eu/articles/posts/dont-ruin-the-root/ Mon, 10 May 2021 08:43:53 +0200 https://berthub.eu/articles/posts/dont-ruin-the-root/ I love Europe, and I want to see the European Union succeed. I also love the Internet, and I want to see it thrive as well. And it therefore pains me that it now appears that the European Union might inadvertently be picking an ugly fight with “The Internet”. UPDATE: I am EXCEPTIONALLY happy to report that through robust engagement with European institutions who understood the problem, the root servers are now fully out of scope of the NIS2 directive! https://berthub.eu/articles/posts/history-of-powerdns-2013-2020-business/ Wed, 21 Apr 2021 18:07:06 +0200 https://berthub.eu/articles/posts/history-of-powerdns-2013-2020-business/ This part of the history of PowerDNS is mostly about our business adventures & merger with Open-Xchange. The technical history of this period is described in part 3a. Business In 2013, PowerDNS was in a crucial phase. Existing business was going well, but we were receiving pointed signals there was trouble on the horizon. Some existing customers were close to deserting us, because we could not provide them with the top-down attention other vendors were lavishing on them. https://berthub.eu/articles/posts/useful-spy-books/ Sun, 18 Apr 2021 13:11:21 +0100 https://berthub.eu/articles/posts/useful-spy-books/ https://berthub.eu/articles/posts/het-gaat-om-de-kerncentrales/ Sun, 11 Apr 2021 10:44:49 +0200 https://berthub.eu/articles/posts/het-gaat-om-de-kerncentrales/ Er is in Nederland een levendige discussie gaande of we in moeten zetten op kernenergie of niet. Afhankelijk van wie je spreekt is kernenergie een groene en noodzakelijke manier om onze CO₂-doelen te halen, of is het overbodige onzin. Ik ben een groot gelover in het idee van kernenergie. Maar onze auto’s en huizen kunnen we niet aandrijven met ideeën. Die drijf je aan met kerncentrales. En daar hebben we het nooit over, de kernindustrie. https://berthub.eu/articles/posts/sadly-you-cant-print-your-own-vaccine/ Tue, 30 Mar 2021 15:46:36 +0200 https://berthub.eu/articles/posts/sadly-you-cant-print-your-own-vaccine/ Brief post, in response to the many many many technical people that propose to print their own mRNA vaccines “now that the source is out there”. I’ve spent a lot of time individually explaining why this is unlikely to happen any time soon, and I thought it a good idea to explain it here as well. Mountains of details on how the vaccines are actually produced can be found on this awesome page by Jonas Neubert and Cornelia Scheitz. https://berthub.eu/articles/posts/galileos-eccentric-satellites/ Sun, 21 Mar 2021 11:11:31 +0100 https://berthub.eu/articles/posts/galileos-eccentric-satellites/ UPDATE: Back in December 2020 when this article was first posted, I noted that some receivers might not be able to deal with the advent of production signals from the eccentric satellites. This has indeed proved to be a problem for U-blox F9 series receivers in a specific configuration. The application note links to this article (thanks!) and also (correctly) states that the signals from the eccentric satellites do not in fact comply with the Galileo Open Service ICD. https://berthub.eu/articles/posts/corona-update-maart-2021/ Sun, 14 Mar 2021 09:42:08 +0100 https://berthub.eu/articles/posts/corona-update-maart-2021/ En toen was het toch weer tijd voor een Corona Update, de eerste sinds november 2020. Doordat er zoveel nieuws is geweest over varianten en vaccins is het zicht een beetje kwijt op waar we nu zijn. En dat is des te vervelender nu de cijfers weer omhoog lijken te gaan. Daarom een samenvatting die eigenlijk heel rooskleurig is, zelfs met de varianten. Dit betekent overigens niet dat de maatregelen al opgeheven kunnen worden! https://berthub.eu/articles/posts/hire-me-semi-popular-science/ Tue, 09 Mar 2021 11:25:34 +0100 https://berthub.eu/articles/posts/hire-me-semi-popular-science/ In short, if you need engaging in-depth articles on your scientific project, your research breakthrough or the grand new technical/space/molecular/medical thing you are building, you can hire me! (Semi-)Popular science writing I do a lot of what I call “(Semi-)popular science writing”. My recent article dissecting the BioNTech/Pfizer SARS-CoV-2 vaccine has racked up over 1.5 million views (so far), and it has done the rounds of the pharmaceutical world where it got favourable reviews. https://berthub.eu/articles/posts/curevac-vaccine-and-wonders-of-biology/ Mon, 08 Mar 2021 18:22:24 +0100 https://berthub.eu/articles/posts/curevac-vaccine-and-wonders-of-biology/ In previous posts I described how the two currently approved mRNA vaccines both use ‘modified nucleosides’ to enhance their efficiency. Meanwhile, a company called CureVac has created an mRNA vaccine that uses regular, unmodified, RNA. It is currently being tested in large scale trials. In this post I explain what the challenges are with this plain RNA approach, and we reverse engineer quite closely what CureVac has done with regular RNA to (hopefully) deliver an effective vaccine. https://berthub.eu/articles/posts/stimulating-innovation/ Sun, 07 Mar 2021 18:51:43 +0100 https://berthub.eu/articles/posts/stimulating-innovation/ This article is part of a series on (European) innovation and capabilities. Periodically I read about governments or institutions wanting to stimulate innovation, often to achieve a certain (worthy) goal. Frequently, the far larger amounts of money that other countries or continents are spending on innovation are then bandied about as justification. And I die a little inside every time that happens. Money and innovation have a very intricate relation. https://berthub.eu/articles/posts/cybersecurity-is-like-food-safety/ Thu, 18 Feb 2021 09:31:12 +0100 https://berthub.eu/articles/posts/cybersecurity-is-like-food-safety/ There are lots of calls to invest in improving cybersecurity. But it struck me that it doesn’t work like that. Not getting hacked is not so much a question of buying the right stuff. It is a question of doing the right things and understanding what you are doing. It is easy to demand that people ‘invest’ in something. You can even supply them with the money to do so. https://berthub.eu/articles/posts/covid-scenarios-and-a-short-break/ Sun, 17 Jan 2021 14:15:50 +0100 https://berthub.eu/articles/posts/covid-scenarios-and-a-short-break/ Hi everyone, With apologies for flooding the airwaves and timelines with way too many posts and tweets, here’s one more post, the last COVID-19 related one for a while. I’ve been trying to provide high quality answers to the many questions I receive via email and various social media. I’ve also been trying to help many many people that found worrying news online & sent it to me, either for reassurance or simply to challenge me. https://berthub.eu/articles/posts/how-tech-loses-out/ Sat, 16 Jan 2021 20:13:17 +0100 https://berthub.eu/articles/posts/how-tech-loses-out/ This article is part of a series on (European) innovation and capabilities. Hi everyone, This is a transcript of my presentation over at the European Microwave Week 2020, actually held in 2021. You can find the video here and the slides here. I’d like to thank Frank van Vliet, general chair of the EMW, for inviting me to do this talk. The words have only been edited lightly - it is still presentation style, so here and there the sentences are not written like how they’d be in a more formal piece of work. https://berthub.eu/articles/posts/genetic-code-of-covid-19-vaccines/ Tue, 12 Jan 2021 13:47:18 +0100 https://berthub.eu/articles/posts/genetic-code-of-covid-19-vaccines/ Translations: 中文, 日本語 As a followup to Reverse Engineering the source code of the BioNTech/Pfizer SARS-CoV-2 Vaccine, here is a look at the genetic code behind some of the other vaccines. I recommend at least skimming the earlier post before delving into this one, unless you are already fluent in modified mRNA bases and protein expression mechanics. To get an extremely full background on all vaccine work, I kindly refer you to excellent posts from Derek Lowe and Hilda Bastian. https://berthub.eu/articles/posts/naliza-izvornog-k%C3%B4da-vakcine-biontech-pfizer-sars-cov-2/ Sun, 10 Jan 2021 21:12:20 +0100 https://berthub.eu/articles/posts/naliza-izvornog-k%C3%B4da-vakcine-biontech-pfizer-sars-cov-2/ Translations: ελληνικά / عربى / 中文 (Weixin video, Youtube video) / 粵文 / bahasa Indonesia / český / Català / český / Deutsch / Español / 2فارسی / فارسی / Français / עִברִית / Hrvatski / Italiano / Nederlands / 日本語 / 日本語 2 / नेपाली / Polskie / русский / Português / Română / Slovensky / Slovenščina / Türk / український / Markdown for translating Dobro došli!

Maar, hij is inzetbaar voor ieder ontspoord of ontsporend familielid of contact. De grote lijn blijft hetzelfde - iemand roept allemaal rare dingen en beïnvloedt zo de rest. Onderstaand verhaal gaat over hoe je dit nuttig om kan draaien. We hebben Coronamaatregelen, en men houdt zich er niet aan. Er zijn prachtige Coronavaccins, en mensen melden luidruchtig deze nooit te gaan nemen. https://berthub.eu/articles/posts/talking-about-covid/ Thu, 07 Jan 2021 15:10:49 +0100 https://berthub.eu/articles/posts/talking-about-covid/ In this page I want to offer some guidance how you can be useful in spreading good Corona information, specifically about vaccines. Importantly, many readers of my blog are the technology help desk for their families - the people that help fixing the wifi, install new computers and generally are useful for solving complex problems. That makes you, the reader very imporant.

Translation: Français / 日本語 In short: the vaccine mRNA has been optimized by the manufacturer by changing bits of RNA from (say) UUU to UUC, and people would like to understand the logic behind these changes. This challenge is quite close to what cryptologists and reverse engineering people encounter regularly. https://berthub.eu/articles/posts/ingenieria_inversa_del_codigo_fuente_de_la_vacuna_de_biontech_pfizer_para_el_sars-cov-2/ Tue, 29 Dec 2020 14:12:20 +0100 https://berthub.eu/articles/posts/ingenieria_inversa_del_codigo_fuente_de_la_vacuna_de_biontech_pfizer_para_el_sars-cov-2/ Translations: ελληνικά / 中文 / Deutsch / Français / Hrvatski / Italiano / नेपाली / Polskie / Português ¡Bienvenidos!

Für alle Fehler zeige ich mich trotzdem selbst verantwortlich, und würde von ihnen gern schnellstmöglich hören: Via bert@hubertnet.nl oder @bert_hu_bert Hinweise zur deutschen Übersetzung bitte an f.zahn@mailbox.org oder @zahnstein Nun, diese Worte wirken zunächst etwas verstörend - ein Impfstoff ist eine Flüssigkeit, die in meinen Arm injiziert wird. https://berthub.eu/articles/posts/reverse-engineering-source-code-of-the-biontech-pfizer-vaccine/ Fri, 25 Dec 2020 20:12:20 +0100 https://berthub.eu/articles/posts/reverse-engineering-source-code-of-the-biontech-pfizer-vaccine/ Translations: ελληνικά / عربى / 中文 (Weixin video, Youtube video) / 粵文 / bahasa Indonesia / český / Català / český / Deutsch / Español / 2فارسی / فارسی / Français / עִברִית / Hrvatski / Italiano / Magyar / Nederlands / 日本語 / 日本語 2 / नेपाली / Polskie / русский / Português / Română / Slovensky / Slovenščina / Srpski / Türk / український / Markdown for translating / Fun video by LlamaExplains / Video version by Giff Ransom https://berthub.eu/articles/posts/history-of-powerdns-2013-2020/ Mon, 21 Dec 2020 20:32:58 +0100 https://berthub.eu/articles/posts/history-of-powerdns-2013-2020/ In this part of the history of PowerDNS, I talk about the technical developments from 2013 to 2020. Over these years many fascinating business & hiring developments also happened, but these are described in a separate post, part 3B of the PowerDNS History. Here are the earlier parts: Part 1, Part 2 For context, the 2013-2020 era is what I would describe as “PowerDNS 3.0” - how we grew from a one (or two) person company to a healthy and thriving department of Open-Xchange. https://berthub.eu/articles/posts/kerstdiner-in-maart/ Sat, 12 Dec 2020 15:44:11 +0100 https://berthub.eu/articles/posts/kerstdiner-in-maart/ Kerstdiner met de familie, moeten we dat nou wel of niet doen dit jaar? Ooit studeerde ik in Delft. Niet dat ik m’n studie daar afgemaakt heb, maar ik heb er toch nog wat geleerd. Een van de dingen die ik daar opgestoken heb is dat je een kerstdiner prima in maart kan houden. Studentenhuizen, jaarclubs, disputen en dergelijke ontdekten met regelmaat dat het moeilijk is om een moment te vinden dat iedereen kan voor het kerstdiner. https://berthub.eu/articles/posts/covid-things-were-not-even-trying/ Tue, 08 Dec 2020 10:13:31 +0100 https://berthub.eu/articles/posts/covid-things-were-not-even-trying/ As COVID-19 drags on, I’ve tried to stay optimistic about scientific and medical developments. By highlighting research, I have hoped to explain (in Dutch and English) how various things will work to defeat COVID-19, and how to look out for your health. But all this time I’ve been frustrated about the things we are not doing, or are not doing enough of. 10th of January 2021 update: The advent of new highly transmissible variants makes this all even worse. https://berthub.eu/articles/posts/history-of-powerdns-2003-2013/ Sun, 29 Nov 2020 16:24:11 +0100 https://berthub.eu/articles/posts/history-of-powerdns-2003-2013/ This is part two of the PowerDNS history as I recall it. As noted in part one, some of this stuff is rather old, and it is entirely possible I am misremembering things. Please do let me know if you find any important omissions or mistakes! At the end of 2002, beginning of 2003, PowerDNS as a going concern was gone. There were no more employees, there were no paying customers. https://berthub.eu/articles/posts/mijn-nieuwe-part-time-baan/ Fri, 27 Nov 2020 13:00:22 +0100 https://berthub.eu/articles/posts/mijn-nieuwe-part-time-baan/ Dit is waarschijnlijk de laatste keer dat ik zal bloggen over mijn nieuwe (part-time) baan. Met ingang van 1 december ben ik één van de drie leden van de commissie die lasten voor de Nederlandse inlichtingen- en veiligheidsdiensten toetst, de Toetsingscommissie Inzet Bevoegdheden (TIB). Als een van de civiele of militaire inlichtingen- en veiligheidsdiensten van Nederland gebruik wil maken van hun bevoegdheden tot aftappen, afluisteren, SIGINT- of hacking moeten ze eerst hun eigen juristen overtuigen, dan hun ministerie en tenslotte de TIB. https://berthub.eu/articles/posts/my-new-part-time-job/ Fri, 27 Nov 2020 12:55:54 +0100 https://berthub.eu/articles/posts/my-new-part-time-job/ So this is likely the last time you see me blog about my new (part time) job. (Nederlandse versie hier). Starting December 1st, I am one of the three members of the board that checks warrants for the Dutch intelligence and security services. This board is called “Toetsingscommissie Inzet Bevoegdheden” or TIB. If either of the civil or the military intelligence and security services of The Netherlands want to use their lawful intercept, SIGINT or hacking (& some other) legal powers, they have to first convince their own jurists, then their ministry and finally the TIB. https://berthub.eu/articles/posts/history-of-powerdns-1999-2003/ Fri, 27 Nov 2020 12:29:55 +0100 https://berthub.eu/articles/posts/history-of-powerdns-1999-2003/ Hi everyone, I have often told the history of PowerDNS, or at least how I recall it, during talks and presentations. As I am about to truly leave DNS and PowerDNS, I thought it was high time to document my recollections. Since this is a 20+ year old story right now, it is very possible I have forgotten or misremembered important things. Do let me know if you miss important things, or if you recall things differently! https://berthub.eu/articles/posts/ikea-tradfri-for-rebooting-serve-or-modem/ Wed, 25 Nov 2020 12:20:33 +0100 https://berthub.eu/articles/posts/ikea-tradfri-for-rebooting-serve-or-modem/ Recently I revamped my home internet, and (hopefully) temporarily ended up with a modem that needs to be power cycled from time to time. We’re working on getting it fixed, but in the meantime I needed a solution for automated power cycling. There are various ways to turn the power off or on from a Linux computer, and some of these are very karmic. You can get a zigbee USB stick and ditto power plugs, and I am sure this is a lot of fun. https://berthub.eu/articles/posts/gevangen-regelgevers/ Tue, 24 Nov 2020 14:44:40 +0100 https://berthub.eu/articles/posts/gevangen-regelgevers/ Er zijn dingen dat als je er van hoort, je ze ineens overal ziet. Wonderlijk genoeg is er zelfs een naam voor, het “Bader–Meinhof phenomenon”. Soms is het niet alleen een effect, maar is het ook echt zo. Dat is het geval bij de “Gevangen Regelgever”, beter bekend als “Regulatory Capture”. Heel in het kort is dit een zeer veel voorkomende situatie waarbij een toezichthouder (of regelgever) langzaam maar zeker de wereld gaat zien door de ogen van de sector waar toezicht op wordt gehouden. https://berthub.eu/articles/posts/hoe-werken-de-nieuwe-corona-vaccins/ Sat, 21 Nov 2020 19:05:02 +0100 https://berthub.eu/articles/posts/hoe-werken-de-nieuwe-corona-vaccins/ Er zijn nu twee vaccins die meer dan 90% effectief lijken te zijn tegen Corona. Dit is heel hard gegaan, maar dat is goed te verklaren. Universitair Hoofddocent en kinderarts Patricia Bruijning heeft het hier heel duidelijk uitgelegd. In het kort, we hebben zo snel vaccins want: Het SARS-CoV-2 virus is een relatief makkelijk doelwit om een vaccin tegen te ontwikkelen. (het is geen griep) De coronavaccins worden ontwikkeld met nieuwe en veel snellere technologie Geld was geen probleem Toelatingsinstanties voor vaccins waren vanaf het begin nauw betrokken. https://berthub.eu/articles/posts/patricia-bruijning-over-corona-vaccins/ Fri, 20 Nov 2020 20:32:29 +0100 https://berthub.eu/articles/posts/patricia-bruijning-over-corona-vaccins/ Ik heb hier een Twitter-draadje van Patricia Bruijning omgezet naar een webpagina, waardoor het verhaal wat makkelijker te lezen is voor mensen zonder Twitter. Dr Bruijning is Universitair Hoofddocent epidemiologie bij UMC Utrecht maar is ook kinderarts. Ze weet dus goed waar ze het over heeft en ook hoe de praktijk werkt. En ik ben erg blij dat ze de tijd heeft genomen ons goed voor te lichten! Hier haar uitleg hoe het komt dat we zo snel een coronavaccin krijgen, en waarom het veilig zal zijn: https://berthub.eu/articles/posts/corona-update-november/ Mon, 16 Nov 2020 12:42:49 +0100 https://berthub.eu/articles/posts/corona-update-november/ Ja, daar zijn we weer! Voor het eerst [sinds juli](https://berthub.eu/articles/posts/corona-update-eind-juli/) weer een Corona Update. Er is inmiddels weer genoeg te melden: vaccins, tests, cijfers, medicijnen en vitamine D. Vaccins Om te beginnen, wow. En nog een keer wow. SINDS VANDAAG ER ZIJN TWEE WERKENDE VACCINS! En nog gekker, ze zijn in februari 2020 al ontworpen, toen het RNA (de broncode) van het virus pas net bekend was. Vergeleken met zelfs maar een paar jaar geleden is dit pure science fiction. https://berthub.eu/articles/posts/dutch-covid-19-data-sources/ Sat, 14 Nov 2020 09:04:20 +0200 https://berthub.eu/articles/posts/dutch-covid-19-data-sources/ As the world focuses on the terrible (but improving) Dutch COVID-19 numbers, I also see a lot of people interpreting the numbers badly. But we can hardly blame folks since most data is only described in Dutch. And even in Dutch the descriptions can be very confusing. So here goes. NOTE: Corrections and additional links & sources are very welcome on bert@hubertnet.nl or @bert_hu_bert. The main sources The RIVM is the “Dutch CDC”. https://berthub.eu/articles/posts/some-dutch-covid-19-figures/ Thu, 12 Nov 2020 14:23:24 +0100 https://berthub.eu/articles/posts/some-dutch-covid-19-figures/ Don’t take this too seriously. As part of my coping mechanisms, I try to understand the latest (Dutch) COVID-19 figures. I documented where to get the raw data and what they mean in an earlier post. Please note I am not trying to make any kind of point with this data, not positive, not negative. I have no agenda, please do not read this as me trying to argue things aren’t that bad or that they are terrible. https://berthub.eu/articles/posts/end-to-end-encryption-european-internet-forum/ Mon, 09 Nov 2020 11:03:55 +0100 https://berthub.eu/articles/posts/end-to-end-encryption-european-internet-forum/ Around a million years ago (it feels like) but actually 9 months ago I delivered a brief talk on end to end encryption for the European Internet Forum at the European Parliament. Because of my new job, I will soon no longer be able to opine on these things as easily. Given the upheaval caused this week by the end-to-end encryption paper from the Council of the European Union, I thought it timely to re-up my little speech now. https://berthub.eu/articles/posts/galileos-ground-segment-problem/ Mon, 19 Oct 2020 13:55:02 +0200 https://berthub.eu/articles/posts/galileos-ground-segment-problem/ The European Global Navigation Satellite System Galileo has recently been suffering from frequent "almost disruptions", most likely partially due to Corona, and possibly also due to Brexit, but in any case due to some historical stinginess. Before I explain what is going on, I should hasten to say that most days of the week, Galileo is working well for most users. But for example, Monday the 28th of September, one satellite was off by a stunning 5 meters. https://berthub.eu/articles/posts/galileos-authentication-algorithm-part-3/ Sun, 13 Sep 2020 11:49:53 +0200 https://berthub.eu/articles/posts/galileos-authentication-algorithm-part-3/ Welcome to part 3 of my series on OSNMA, the proposed Galileo Navigation Message Authentication protocol. This part can be read independently from part 1 and part 2, but it might be useful to read the introduction to part 1. This post attempts to explain GPS (GNSS) jamming and spoofing, so it might be a useful read even if you don’t care about Galileo or its authentication. As usual, I’ve been helped tremendously by Daniel Estévez & many other researchers and Galileo professionals, and again I am very greatful for all the links, corrections, suggestions and knowledge you provided. https://berthub.eu/articles/posts/vitamine-d-de-motorolie-covid-19/ Sun, 13 Sep 2020 10:43:38 +0200 https://berthub.eu/articles/posts/vitamine-d-de-motorolie-covid-19/ We horen veel over hoeveel mensen er nu besmet raken met COVID-19. Tegelijk viel het tot begin oktober erg mee met de ziekenhuisopnames en sterfgevallen. Ik kan ook niet verklaren hoe dat precies komt (het is niet alleen leeftijd), maar ik wil het in dit artikel wel hebben over “de zonlichtvitamine”, vitamine D. Want nu in september hebben we net een zomer lang zon gehad, en in maart kwamen we vers uit de winter. https://berthub.eu/articles/posts/galileos-authentication-algorithm-part-2/ Wed, 26 Aug 2020 10:43:09 +0200 https://berthub.eu/articles/posts/galileos-authentication-algorithm-part-2/ Recapping from part 1: Galileo will soon add cryptographic signatures to the navigation messages. These cryptographic signatures are made with symmetric cryptography, which means clever techniques are required to prevent receivers from impersonating the network. The key to the technique is first signing messages, and only later disclosing the key used for the signatures, thus invalidating it for further use. Receivers can however verify that earlier signatures were indeed made with that key. https://berthub.eu/articles/posts/galileos-authentication-algorithm-part-1/ Thu, 13 Aug 2020 20:50:09 +0200 https://berthub.eu/articles/posts/galileos-authentication-algorithm-part-1/ Position, velocity and time (PVT) information can be a ’nice to have’, but in other circumstances knowing place and time has legal or military importance as well. Heavy vehicles for example are typically outfitted with tachographs that track driver speed and/or location. This has importance for rest regulations, but also to check if loads are actually from where they say they are. Our Global Navigation Satellite Systems so far are broadcasting unauthenticated data, at least to civilian users. https://berthub.eu/articles/posts/corona-update-eind-juli/ Sat, 25 Jul 2020 14:42:06 +0200 https://berthub.eu/articles/posts/corona-update-eind-juli/ Toch weer een kleine Corona-update, vrij snel na de vorige van 1 juli. Want poeh, gaat het nou ineens weer mis in Nederland? Of valt het mee? Moeten we allemaal aan de maskers en komt het dan goed? En gaan de vaccins en medicijnen ons redden voor de winter? In tegenstelling tot vele roeptoeters heb ik daar ook allemaal geen zekere antwoorden op, maar hier toch een set updates over de meest recente ontwikkelingen. https://berthub.eu/articles/posts/the-curious-case-of-galileo-e24/ Sat, 18 Jul 2020 09:07:23 +0200 https://berthub.eu/articles/posts/the-curious-case-of-galileo-e24/ GPS, GLONASS, Galileo, BeiDou (Global Navigational Satellite Systems, GNSS) are miracles of engineering. And within any complex system hide surprises and unsuspected complications. In this post I go over how we resolved an odd observation: that everyone (including major institutions) reported that one of the Galileo satellites (E24) appeared to be off by 1.5 meters, while actual positioning equipment (like phones) showed no problems at all. Through the explanation, we’ll casually learn a thing or two about the cool concept of multi-frequency GNSS. https://berthub.eu/articles/posts/uputronics-gps-rtc-expansion-board/ Thu, 09 Jul 2020 13:38:00 +0200 https://berthub.eu/articles/posts/uputronics-gps-rtc-expansion-board/ Hi everyone, Disclaimer: this is a review of a free sample I got sent by Uputronics. I recently spotted on Twitter that Uputronics had launched a GPS/RTS Raspberry Pi Expansion Board, and that they were looking for worthy projects to test it. I thought our Galileo/GPS/BeiDou/GLONASS monitoring project galmon.eu might be worthy and Uputronics agreed. Relevant for our purposes, this is an actual ’timing receiver’. Any GNSS chip will get you a location, but some of them go the extra mile to also deliver a very stable clock signal. https://berthub.eu/articles/posts/briefly-on-the-galmon-weekly-report/ Tue, 07 Jul 2020 11:54:59 +0200 https://berthub.eu/articles/posts/briefly-on-the-galmon-weekly-report/ I have a longer story brewing, but in this post I want to briefly announce the “Galmon.eu unofficial Weekly Performance Report”. This is a blog post version of an earlier Twitter thread. I’m very proud to present the first full Galmon.eu Weekly Galileo Report! And the good news is: it was a good week with very little to report. The email has just gone out, but you can also find it here. https://berthub.eu/articles/posts/corona-update-juli/ Wed, 01 Jul 2020 17:37:17 +0200 https://berthub.eu/articles/posts/corona-update-juli/ Nu het RIVM gestopt is met dagelijkse updates vond ik dat het tijd was dat gat dan maar te vullen, al is het maar voor een dag. Een nieuwe Corona Update “hoe gaat het nu met”. De vorige was alweer van 21 april! De “Ik ben geen expert, maar toch”-factor Een boel dansleraren en opiniepeilers zijn inmiddels COVID-19 experts. In deze post heb ik erg mijn best gedaan alleen dingen te melden die we heel zeker weten. https://berthub.eu/articles/posts/covid-19-t-cells/ Fri, 05 Jun 2020 18:52:24 +0200 https://berthub.eu/articles/posts/covid-19-t-cells/ When COVID-19 burst on to the scene, tests quickly showed that the everyone was susceptible - no pre-existing antibodies were found that bound to the SARS-CoV-2 virus. This led to dire predictions that over 80% of the population might eventually fall ill. Now more than six months in, this has not happened, and it does not appear to be close to happening. A few months ago, noted virologist Christian Drosten mused in his (German) podcast that some people might have a level of immunity after all, but he wasn’t yet sure. https://berthub.eu/articles/posts/vitamin-d-the-new-covid-19-chloroquine/ Sat, 30 May 2020 17:52:44 +0200 https://berthub.eu/articles/posts/vitamin-d-the-new-covid-19-chloroquine/ Welcome to this post, in which we’ll be taking a trip through the wild and bumpy ride that has been Vitamin D & sunlight research over the past few decades, and what it might mean for COVID-19. As with my previous post, before any non-specialist attempts to write something on COVID-19, we should wonder: are any actual experts already writing on this, and if not, why not. Enough badly informed stuff has already been published by amateurs that before posting we should be certain we are actually being helpful. https://berthub.eu/articles/posts/covid-19-rampant-speculation-may-2020/ Sun, 24 May 2020 10:49:02 +0200 https://berthub.eu/articles/posts/covid-19-rampant-speculation-may-2020/ It turns out that so far, I have written over 44000 words on COVID-19. I’ve tried very hard to only report the best and most trustworthy science, but I did strive to include interesting new insights that were not yet mainstream. As an example, I spoke about vitamin D and sunlight real early, which now indeed appears to be a thing. No guarantees yet, but it definitely is a thing. https://berthub.eu/articles/posts/dna-grep-2019-ncov/ Fri, 22 May 2020 17:18:33 +0200 https://berthub.eu/articles/posts/dna-grep-2019-ncov/ This post is dedicated to lab technicians everywhere doing the difficult work institutes and hospitals rely on to investigate disease and keep us healthy. Lab work requires high precision, deep understanding, is physically demanding, and can even be dangerous. Although our healthcare systems & universities would come to a grinding halt without lab technicians, they are often almost literally invisible somewhere far away. Thank you all for your hard work! https://berthub.eu/articles/posts/r-and-the-herd/ Thu, 14 May 2020 15:27:00 +0200 https://berthub.eu/articles/posts/r-and-the-herd/ Before any non-specialist attempts to write something on COVID-19, we should wonder: are any actual experts already writing on this, and if not, why not. Enough badly informed stuff has already been published by amateurs that before posting we should be certain we are actually being helpful. October 2022 UPDATE: I've removed the rest of this post. Turns out everyone (including me) was wrong, and we didn't understand pandemics of respiratory diseases very well. https://berthub.eu/articles/posts/mitochondrien/ Sun, 10 May 2020 17:15:46 +0200 https://berthub.eu/articles/posts/mitochondrien/ Een spontane wetenschapsupdate, omdat het Moederdag is, en speciaal voor iedereen die het nu zonder zijn of haar moeder moet doen. Want, we dragen allemaal letterlijk een beetje onze moeder bij ons! Deze post is dankbaar geïnspireerd door deze Twitter thread van Efra Rivera-Serrano, PhD. Bron: Efra Rivera-Serrano, link Ons DNA is een mix van dat van onze beide ouders. Maar, in vrijwel al onze cellen leeft een wonderlijk wezentje wat we echt alleen van onze moeder geërfd hebben. https://berthub.eu/articles/posts/corona-binnen/ Sat, 09 May 2020 09:25:07 +0200 https://berthub.eu/articles/posts/corona-binnen/ Het RIVM, het “Outbreak Management Team” en het kabinet werken samen aan gedegen adviezen. Uiteindelijk worden dit ook wel de juiste adviezen, al blijft men soms lang aan oude dingen hangen: mensen zonder symptomen zijn niet besmettelijk (oeps, toch wel), maskers hebben geen zin (oeps, ze helpen wel voorkomen dat je andere mensen besmet). Uiteindelijk maakt men de draai wel, maar het kost even. Nu de scholen weer opengaan vroeg ik me af, wat weten we eigenlijk over hoe mensen besmet raken met COVID-19? https://berthub.eu/articles/posts/corona-hoe-en-wat/ Mon, 27 Apr 2020 08:49:38 +0200 https://berthub.eu/articles/posts/corona-hoe-en-wat/ Ik blog al maanden over SARS-CoV-2 aka COVID-19 aka “het coronavirus”, waarbij ik grotendeels dingen uitleg en verwijs naar positieve ontwikkelingen. Ook zijn er stukjes over medische experimenten, over ons immuunsysteem en recent iets korts over het vermoedelijke belang van goede ventilatie om COVID-19 besmettingen tegen te gaan. Ik houd van de wetenschap en ben trots op het mooie onderzoek wat hier in internationale samenwerking verricht wordt. Maar nu dan toch een zeurstuk: waarom weten we niet waar en hoe mensen in Nederland besmet raken? https://berthub.eu/articles/posts/corona-update-21-april/ Tue, 21 Apr 2020 14:30:40 +0200 https://berthub.eu/articles/posts/corona-update-21-april/ Ja, daar zijn we weer. Bij het beëindigen van de serie dagelijkse Corona updates had ik aangekondigd nog terug te komen als er weer wat te melden was. Bij deze een aflevering “hoe gaat het nu met”, met daarin nieuws over hoe het verder gaat met eerder gemelde ontwikkelingen. Daarnaast twee stukjes op veler verzoek: hoe gaat het met het testen en kan de economie al weer open. Om te beginnen, op 25 maart zei ik “De samenvatting is dat als iedereen zich aan de regels houdt (BLIJF THUIS, HOUD AFSTAND) we het waarschijnlijk net binnen de capaciteit gaan houden in Nederland”, en dat bleek dus te kloppen. https://berthub.eu/articles/posts/tracing-app-backend/ Tue, 14 Apr 2020 20:00:22 +0200 https://berthub.eu/articles/posts/tracing-app-backend/ bert@hubertnet.nl / @bert_hu_bert / LinkedIn Very quick post. The Dutch government just launched a tender for “digital technologies that can help with Corona”. The tender includes words on privacy sensitive contact tracing, it explicitly refers to PEPP-PT, the Pan-European Privacy-Preserving Proximity Tracing project. Responses are due on Tuesday the 14th of April, 12:00 (noon). The question/answer form asks if you can do a demo on the 18th of April and have something that could be rolled out on the 28th. https://berthub.eu/articles/posts/tracing-app-thoughts-and-links/ Sat, 11 Apr 2020 13:46:27 +0200 https://berthub.eu/articles/posts/tracing-app-thoughts-and-links/ As many countries are now managing to drive down their COVID-19 epidemic, thoughts are turning to how to manage the outbreak beyond the “lockdown”. The restrictions we live under now do appear to work, but for multiple reasons, they’ll be hard to maintain. When the epidemic was small, it was possible to trace every new infection and isolate potential new cases. This did buy time, but for most countries, “the cat was out the bag already”. https://berthub.eu/articles/posts/de-dagelijkse-corona-update/ Mon, 06 Apr 2020 13:31:55 +0200 https://berthub.eu/articles/posts/de-dagelijkse-corona-update/ Ik heb op Facebook beloofd iedere dag een "Corona Update" te sturen met ontwikkelingen die hoopgevend zijn, terwijl ik het wel realistisch houd. Hier verzamel ik de updates zodat ze ook buiten Facebook te bekijken zijn. Er is genoeg nieuws om je zorgen over te maken dat ik het nodig vind ook dingen die kunnen helpen te belichten. Mensen die me kennen weten dat ik geen optimist ben, het is geen “goed nieuws show” hier. https://berthub.eu/articles/posts/corona-trial-math/ Sat, 04 Apr 2020 13:27:10 +0200 https://berthub.eu/articles/posts/corona-trial-math/ Many many possible medicines are being touted as possibly being helpful in fighting COVID-19. Here’s a small list where we have some initial results or at least anecdotes: (hydroxy)chloroquine, with azithromycin or zinc: This is the “tech-bro” favorite right now, partially based on recommendations from Elon Musk and Donald Trump, two noted medical professionals. There have been a few reports on this working or not working. This article argues that an alternation of negative and positive results actually is to be expected, even if the treatment is fairly effective, which it might be. https://berthub.eu/articles/posts/immune-system/ Wed, 01 Apr 2020 22:27:10 +0200 https://berthub.eu/articles/posts/immune-system/ (On this page in Dutch I post daily bits of realistic but hopeful Corona news. Here is a somehat rough translation of an article on our immune system I posted there, because I think it might also be useful for people that don’t speak Dutch). Wednesday, April 1st COVID-19 can only live thanks to us. Viruses cannot reproduce independently, they need our help. And our immune system makes this very hard, as aptly explained in this excellent xkcd comic: https://berthub.eu/articles/posts/corona-science/ Mon, 30 Mar 2020 11:09:45 +0100 https://berthub.eu/articles/posts/corona-science/ Hello and welcome to this stream of consciousness I dare to call "the Corona Science Journal".

Those who have read the previous posts will recall that antibodies from people who have already been cured can help us to be vaccinated temporarily, or even heal us faster from disease. https://berthub.eu/articles/posts/corona-selftest-warning/ Sat, 21 Mar 2020 14:12:11 +0100 https://berthub.eu/articles/posts/corona-selftest-warning/ Several sites are now shipping “COVID-19 self test kits” or perhaps “Coronavirus self test kits”. These claim to detect the virus in 10 minutes based on a drop of blood. These rapid self-test kits are currently: Likely fake Even if not fake, they do NOT test for the virus, they do NOT do what you think they do Even if they do what they are supposed to, these tests have not been validated and could be wrong a lot. https://berthub.eu/articles/posts/ict-van-levensbelang/ Fri, 14 Feb 2020 09:00:00 +0100 https://berthub.eu/articles/posts/ict-van-levensbelang/ Gisteren verscheen het rapport “Patiëntveiligheid bij ICT-uitval in ziekenhuizen” van de Onderzoeksraad voor veiligheid. Omdat ik een bescheiden bijdrage heb geleverd aan dit rapport voel ik me geroepen een stukje te schrijven over wat in het rapport het “ICT-fundament” wordt genoemd. Voor de volledige duidelijkheid, wat ik hier schrijf heeft niets te maken met de Onderzoeksraad en ook niet specifiek met de inhoud van het rapport. Zie het als een overdenking over bedrijfskritische ICT. https://berthub.eu/articles/posts/sars-ncov-comparison/ Fri, 24 Jan 2020 13:42:01 +0100 https://berthub.eu/articles/posts/sars-ncov-comparison/ https://berthub.eu/articles/posts/5g-elephant-in-the-room/ Mon, 20 Jan 2020 15:00:00 +0100 https://berthub.eu/articles/posts/5g-elephant-in-the-room/ This article is part of a series on (European) innovation and capabilities. In a break from the usual GPS/Galileo, DNA and C++ posts, here is a bit on 5G and national security. It turns out that through PowerDNS and its parent company Open-Xchange, we know a lot about how large scale European communication service providers work - most of whom are our customers in some way. In addition, in a previous life I worked in national security and because of that I have relevant knowledge of how governments (your own and foreign ones) “interact” with telecommunication providers. https://berthub.eu/articles/posts/galmon-project/ Wed, 08 Jan 2020 13:53:08 +0100 https://berthub.eu/articles/posts/galmon-project/ Welcome to the Galmon project! Our goals are to monitor the major Global Navigation Satellite Systems, including GPS, GLONASS, Galileo and BeiDou, but also Space Base Augmentation Systems like WAAS, EGNOS and GAGAN. Galmon is an open source & open data project with a community of over 30 station operators running more than 50 receivers. Some history of the project may be found in the second part of this blog post, and on this page on the big Galileo 2019 outage. https://berthub.eu/articles/posts/update-2019-powerdns-galileo-ripe-doh/ Wed, 01 Jan 2020 15:37:52 +0100 https://berthub.eu/articles/posts/update-2019-powerdns-galileo-ripe-doh/ Last year I wrote a post listing what I had been doing in 2018, because it turned out it was a lot, so much that it was useful to summarise it somewhat. This year there is less to report, but people have wondered what I’ve been up to. And I’ve learned that if you leave room for speculation about your intentions, wrong answers tend to come up. This (professional) year for me mostly consisted of two things: DNS over HTTPS and Galileo. https://berthub.eu/articles/posts/what-is-life/ Mon, 30 Dec 2019 14:44:26 +0100 https://berthub.eu/articles/posts/what-is-life/ What is life? This question keeps many people awake at night and has led to rafts of definitions, some involving features (procreation, metabolism and so forth), some involving chemistry, entropy or energy flux and some are of a more philosophical bent. A BBC article noted there are over 100 definitions of life and it claims all are wrong. And indeed it does appear to be quite a challenge - every hard and fast rule is violated somewhere in biology. https://berthub.eu/articles/posts/biologists-physics-envy/ Sat, 07 Dec 2019 14:53:42 +0100 https://berthub.eu/articles/posts/biologists-physics-envy/ Note: This article covers a lot of well-trodden ground, although this post has the benefit of 1) being rather brief and 2) advancing slightly on from earlier work. Noam Chomsky wrote 39 dense pages of philosophy on this subject in “Mysteries of Nature: How Deeply Hidden”. Evolutionary’s leading light Ernst Meyr wrote a whole book called “What makes biology unique”. Finally, a lot of this thinking is also covered in the quite philosophical work “The way of the Cell” by Franklin M. https://berthub.eu/articles/posts/anonymous-help/ Mon, 02 Dec 2019 13:09:45 +0100 https://berthub.eu/articles/posts/anonymous-help/ Dear anonymous internet user, dear corporate employee hiding behind a gmail.com address, dear “GitHub account with a single issue”, Thank you for your interest in my free software, my project or the documentation I wrote for you.

Here we’ll only focus on the outage - the potential underlying reasons behind it are described in the full article. Since the week-long outage in July I’ve been fascinated by Galileo and, together with a wonderful crew of developers, experts and receiver operators, have learned so much about what I now know are called ‘Global Navigation Satellite Systems’ or GNSS. https://berthub.eu/articles/posts/state-of-galileo-and-accident/ Thu, 07 Nov 2019 09:47:53 +0100 https://berthub.eu/articles/posts/state-of-galileo-and-accident/ By bert hubert / bert@hubertnet.nl In this post I want to document some mostly non-technical aspects of the EU’s Galileo Satellite Navigation Network. I will also share some observations on how things are going, and perhaps how they could be improved. NOTE: A shorter version of this article, focusing only on the July outage, can be found here. Since the week-long outage in July I’ve been fascinated by Galileo and, together with a wonderful crew of developers, experts and receiver operators, have learned so much about what I now know are called ‘Global Navigation Satellite Systems’ or GNSS. https://berthub.eu/articles/posts/gps-lesson/ Mon, 14 Oct 2019 20:09:53 +0200 https://berthub.eu/articles/posts/gps-lesson/ The Netherlands is struggling with a shortage of primary school teachers, which as a nice side effect means that I get ample opportunities to do technical propaganda in the name of education. This is a quick writeup of a lesson on how GPS (or in general, satellite based navigation) works. I’d like to thank Jasper Vos and Michel Dingen of OBS De Notenkraker for the opportunity & the very useful feedback on the lessons! https://berthub.eu/articles/posts/economist-how-the-web-leaks/ Sat, 05 Oct 2019 13:08:38 +0200 https://berthub.eu/articles/posts/economist-how-the-web-leaks/ Note: For context, please see this article on the Economist Job. I also want to thank Job Snijders who was of great help in writing this article. How the Internet Leaks A few weeks ago large swathes of the internet stopped working around the world. The cause was quickly found: a computer networking mistake over at a specialty metals company based in Pittsburgh, Pennsylvania. Earlier that month, a similar accident took down payment terminals in The Netherlands because of a misconfiguration in a Swiss datacenter which rerouted key parts of the internet to China. https://berthub.eu/articles/posts/economist-pan-genome/ Sat, 05 Oct 2019 13:05:35 +0200 https://berthub.eu/articles/posts/economist-pan-genome/ Note: For context, please see this article on the Economist Job. This is a condensed and updated version of my earlier post On the pan-genome. Towards a multi-stranded genome Given that the completion of the human genome project was announced in 2003, one could be forgiven for thinking the kinks would have been worked out by now. It turns out however that as published today, the human DNA reference sequence is neither complete nor a good description of mankind. https://berthub.eu/articles/posts/economist-job/ Sat, 05 Oct 2019 12:52:08 +0200 https://berthub.eu/articles/posts/economist-job/ Over the holiday, I ran into this job advertisement from The Economist: The Economist is looking for a new Science and Technology correspondent. Knowledge of the field, an ability to write informatively, succinctly and wittily, and an insatiable curiosity are more important attributes than prior journalistic experience. Please send a CV, a brief letter introducing yourself, and an article of 600 words suitable for publication to xxxx@economist.com.

I’m a proud European, and I think we should have our own well-functioning navigation system, so I tried to figure out what was going on. Surely someone was monitoring this stuff in public? I come from the internet where we monitor all the things, if someone asked for it or not. https://berthub.eu/articles/posts/beidou-satellites/ Mon, 02 Sep 2019 08:37:13 +0200 https://berthub.eu/articles/posts/beidou-satellites/ Hi everyone, As noted previously I’ve gone all in on GNSS monitoring. GNSS is the generic term for GPS, Galileo, GLONASS and BeiDou satellites. Eventually a big blog post will come out, but meanwhile you can see the results on galmon.eu. A few days ago, an unknown GLONASS satellite started transmitting signals on slot R26 and I tried to figure out which one it was. By definition, GNSS satellites broadcast their own very precise location & speed, which makes it possible to match up their orbit to published “TLEs”, which document where objects in space are. https://berthub.eu/articles/posts/galileo-notes/ Tue, 30 Jul 2019 15:35:10 +0200 https://berthub.eu/articles/posts/galileo-notes/ I’ve recently been spending quite some time on the EU’s Galileo Navigation Satellite System. In this post you’ll find some rough notes on things I’ve found out, both about how to receive data & how to understand the Galileo ephemeris parameters. Feedback is very welcome on bert@hubertnet.nl or @bert_hu_bert! I’m no Galileo specialist, so I am sure this page could be better. Please also let me know if this page has been useful to you. https://berthub.eu/articles/posts/on-the-pan-genome/ Fri, 12 Jul 2019 09:10:21 +0200 https://berthub.eu/articles/posts/on-the-pan-genome/ In this post I want to shine a light on an important development within the world of DNA which shows how much DNA and the world of computing are now intertwined. It turns out we share important problems, like in this case: file formats. Note: I expect to be posting more DNA material as part of my efforts to write a book on this fascinating subject. If you enjoy reading about DNA, you might like the links/presentations/videos found on this page. https://berthub.eu/articles/posts/from-gnuplot-to-matplotlib-pandas/ Mon, 01 Apr 2019 09:59:00 +0100 https://berthub.eu/articles/posts/from-gnuplot-to-matplotlib-pandas/ I’ve been using gnuplot since.. like forever. It is one of my best friends in plotting data and discovering what is going on. But for all its greatness, you do tend to run into a wall - once you step outside the things gnuplot is good at, suddenly large heaps of awk, sort, unique and odd shell scripts are required to get to the next level. This is no criticism of gnuplot - it is great for what it is for. https://berthub.eu/articles/posts/iostreams-unexpected/ Sun, 17 Mar 2019 17:46:37 +0100 https://berthub.eu/articles/posts/iostreams-unexpected/ In previous articles, I’ve waxed rhapsodic about how great C++ is. I also noted there however that every language, C++ included, has its dark sides. Some languages have an unavoidable pervasive dark side, like being slow or hard to multithread, for C++ that dark side is mostly its complexity. In this post I want to zoom in on a specific ‘gotcha’ that recently took me several hours to resolve. I wrote this piece so anyone running into the same issue might find out about it if they search the web. https://berthub.eu/articles/posts/what-i-did-in-2018/ Sun, 30 Dec 2018 14:26:04 +0100 https://berthub.eu/articles/posts/what-i-did-in-2018/ This is a more personal post than I usually write, and it was prompted by several people asking what I had been up to lately. It turns out that it is somewhat of a story. It is a long story too. Since the beginning of 2018 day to day management of PowerDNS is now truly in the hands of professionals. I’m very proud to report that PowerDNS has not only survived the transition to Open-Xchange but is actually thriving & has achieved sufficient revenues & talented staff that we’ve solved the famous open source “what if Bert gets hit by a bus” problem. https://berthub.eu/articles/posts/liveblog/ Tue, 27 Nov 2018 12:26:28 +0100 https://berthub.eu/articles/posts/liveblog/ Yesterday, NASA landed its InSight mission on Mars, and it all worked! The landing happened between 8 and 9PM local time, but I wanted to share the excitement with my kids’ classmates from school (aged between around 9 and 10), so I needed something that worked remotely. NASA provided a wonderful webcast in English, and although many children here in The Netherlands can follow that, I expected the stream to need more narration for the kids to truly experience the excitement of landing on another planet. https://berthub.eu/articles/posts/philosophy-of-software-design/ Thu, 18 Oct 2018 12:07:35 +0200 https://berthub.eu/articles/posts/philosophy-of-software-design/ John Ousterhout, of TCL fame, has written a book that is as small (literally) as it is important. Weighing in at 178 none too big pages, it takes us on an inspired trip through what John has learned over the decades. There is no shortage of thought on programming. There is also no shortage of people doing programming. What is rare however is a compendium of mature insights from someone that clearly still is into programming. https://berthub.eu/articles/posts/linus-communications/ Tue, 18 Sep 2018 10:24:42 +0200 https://berthub.eu/articles/posts/linus-communications/ Linus Torvalds has long been one of my heroes. The invention of Linux & the subsequent development of Git were technical and organizational miracles. You could fill a book simply by quoting examples of Linus dissecting technical problems to their components and making it obvious what should happen. However, over the past decade, Linus’ communication style has degraded from ‘Finnish style robust’ to needlessly hurtful screeds, tearing into people who did not deserve that. https://berthub.eu/articles/posts/cpp-6/ Fri, 17 Aug 2018 21:58:51 +0200 https://berthub.eu/articles/posts/cpp-6/ In part 5 we discussed smart pointers, placement new and the powerful move constructor. As you may have gathered by now, parts 1 through 5 were a pitch to sell modern C++ to existing C specialists. To do so, I tried to show the best and most immediately useful parts of C++. Note: part 1 is here. As noted earlier, no language is perfect, and not all features of C++ are as good or as spectacular. https://berthub.eu/articles/posts/cpp-rust-go/ Mon, 30 Jul 2018 14:35:51 +0200 https://berthub.eu/articles/posts/cpp-rust-go/ I recently wrote a series of posts called ‘Modern C++ for C Programmers’. I mentioned in the introduction: “I hope to convince C programmers to give ‘2017 era C++’ (which is entirely unlike 2003 C++) another good look. (…) My goal is that when you go look for a new language to learn (say, Go or Rust), you will hopefully consider modern C++ as well.” Over the weeks as I posted new parts, I was blown away by the interest. https://berthub.eu/articles/posts/cpp-intro/ Sat, 28 Jul 2018 13:29:55 +0200 https://berthub.eu/articles/posts/cpp-intro/ 2018 is an exciting time to be a programmer, with so many good “full service” programming languages to choose from: C, C++ 2017, Go, Python, Rust and who knows Swift too. Programming languages are complicated beasts - even the simplest languages have specifications that run (or would run) in the hundreds of pages, and once you include everything, no serious language is likely to clock in under a thousand. With this comes the fact that every programming language has good parts, and frequently even more bad parts. https://berthub.eu/articles/posts/cpp-5/ Wed, 25 Jul 2018 11:26:51 +0200 https://berthub.eu/articles/posts/cpp-5/ Welcome back! In part 4 we went over the nitty-gritty of lambdas and how to store them, we explored the relation between the various C++ algorithms and containers, plus we took a stroll through some non-standard containers with exceptional capabilities. Note: part 1 is here. In this probably final part 5, we’ll be going over some of the most powerful stuff in modern C++: “perfect” reference counting and the concept of std::move. https://berthub.eu/articles/posts/cpp-4/ Thu, 12 Jul 2018 13:07:40 +0200 https://berthub.eu/articles/posts/cpp-4/ Welcome back! In part 3 I discussed classes, polymorphism, references and templates, and finally built a source indexer out of basic containers that achieves 60MB/s indexing speed. In this part we continue with further C++ features that you can use to spice up your code ’line by line’, without immediately having to use all 1400 pages of ‘The C++ Programming Language’. There is frequent reference to the indexing example from part 3 so you may want to make sure you know what that is about. https://berthub.eu/articles/posts/werving/ Mon, 09 Jul 2018 11:05:31 +0200 https://berthub.eu/articles/posts/werving/ Welkom! Veel bedrijven en scholen in mijn omgeving worstelen op dit moment met het vinden van personeel. Sinds 1999 neem ik mensen aan en help ik bij werving, voor mijn eigen bedrijf & dat van anderen, maar ook voor scholen en instellingen. En als ik eerlijk ben, ik ben er inmiddels best goed in. In ieder geval ben ik onvoorstelbaar trots op de uitstekende mensen die ik heb kunnen overtuigen bij me te werken! https://berthub.eu/articles/posts/cpp-3/ Mon, 02 Jul 2018 21:30:31 +0200 https://berthub.eu/articles/posts/cpp-3/ Welcome back! In part 2 I discussed basic classes, threading, atomic operations, smart pointers, resource acquisition and (very briefly) namespaces. In this part we continue with further C++ features that you can use to spice up your code ’line by line’, without immediately having to use all 1400 pages of ‘The C++ Programming Language’. Various code samples discussed here can be found on GitHub. If you have any favorite things you’d like to see discussed or questions, please hit me up on @bert_hu_bert or bert@hubertnet. https://berthub.eu/articles/posts/cpp-2/ Thu, 14 Jun 2018 20:26:28 +0200 https://berthub.eu/articles/posts/cpp-2/ Welcome back! In part 1 I discussed how std::string and std::vector interoperate with C, including with the C standard library qsort call. We also discovered that the C++ std::sort is 40% faster than C qsort because C++ is able to inline the comparison function. In this part we continue with further C++ features that you can use to spice up your code ’line by line’, without immediately having to use all 1400 pages of ‘The C++ Programming Language’. https://berthub.eu/articles/posts/c++-1/ Wed, 13 Jun 2018 21:04:19 +0200 https://berthub.eu/articles/posts/c++-1/ Welcome to part 1 of Modern C++ for C Programmers, please see the introduction for the goals and context of this series. In this part we start with C++ features that you can use to spice up your code ’line by line’, without immediately having to use all 1400 pages of ‘The C++ Programming Language’. Various code samples discussed here can be found on GitHub. Relation between C and C++ C and C++ are actually very close relatives, to the point that many compilers have unified infrastructure for both languages. https://berthub.eu/articles/posts/meetings/ Tue, 29 May 2018 19:13:46 +0200 https://berthub.eu/articles/posts/meetings/ Ahhh.. meetings. The one old school company thing that survives in this agile, open-office, ‘remote first’, nomadic worker world. And it is easy to see why: the ‘meeting’ is the last guaranteed way to get everyone to pay attention for an hour, or at least, pretend to. It still is rare for people to fake attending two meetings at the same time in any case. The late great Andrew S. Grove, long time CEO of Intel and overall hero engineer, wrote the massively important book High Output Management. https://berthub.eu/articles/posts/spectre-meltdown/ Sat, 06 Jan 2018 10:34:05 +0100 https://berthub.eu/articles/posts/spectre-meltdown/ Comments are very welcome on bert@hubertnet.nl or @bert_hu_bert. Update: several constructive remarks have been used to improve this text. Thanks! In this post I will attempt to fully explain the Spectre and Meltdown vulnerabilities in an accessible way. I decided to write it up after I realised it took me more than a day to figure it out, even though I’ve been doing security related stuff on CPUs for 20 years. https://berthub.eu/articles/posts/kolmo/ Tue, 24 Oct 2017 10:24:57 +0200 https://berthub.eu/articles/posts/kolmo/ Welcome to Kolmo There are three avenues to learn about Kolmo (GitHub). There are two Youtube videos, one from the most excellent NLNOG 2017, the other from the equally excellent UKNOF 38. These videos explain a lot of the the history and the ‘why’ behind Kolmo. There is also the kolmo.org website, which is ‘self-hosted’ by the ws Kolmo-powered webserver. Finally, there is this post, in which I focus on what Kolmo actually does, without spending much time on the ‘why’ or the history. https://berthub.eu/articles/posts/ethernet-cables/ Sat, 30 Sep 2017 20:07:40 +0200 https://berthub.eu/articles/posts/ethernet-cables/ Some brief notes on making ethernet cables With thanks to the most excellent NLNOG for a lot of mostly correct advice! Friends will tell you “crimping” ethernet cables is easy. Most of your friends either have overly rosy memories, or have practiced on 200 cables before telling you it is now easy. It is not easy. This page is for if you have a few extra euros/dollars/coins to spare, and don’t want to spend rare hours of concentrated effort to crimp an ethernet cable using unfamiliar equipment and supplies. https://berthub.eu/articles/posts/bol-com-vacature/ Sat, 19 Aug 2017 21:08:33 +0200 https://berthub.eu/articles/posts/bol-com-vacature/ Onlangs vond ik via LinkedIn een advertentie voor de vacature ‘Senior Category Manager Domestic Appliances’ bij bol.com. Hierin stond zoveel wartaal dat ik het de moeite vond een ‘best of’ selectie te delen op Facebook. Daar vond men het ook erg grappig. Desondanks is het de moeite waard de vacature te decoderen: wat staat hier nou eigenlijk? Of exacter, wat bedoelen deze mensen. Komt ie.

The first presentation was recorded by the wonderful CCC C3VOC streaming crew, the second one by my friend Bart Smit (who is also wonderful). Without making this post too long, I want to thank everyone who helped me do this presentation — a lot of people contributed time, advice, recording abilities, great questions and enthusiasm. https://berthub.eu/articles/posts/talking-to-technical-people/ Fri, 07 Jul 2017 20:35:35 +0200 https://berthub.eu/articles/posts/talking-to-technical-people/ (Don’t) drop the hint: communicating with technical people This post is a subset of the presentation “Escaping the data center — tales from a recovering manager”. Video, slides. When we communicate at the office, we frequently do not directly say what we mean. A common conversation might go like this “Hey John, we did a survey and it turns out people can’t find what they are looking for on our website”. https://berthub.eu/articles/posts/encrypting-ip-addresses/ Sun, 07 May 2017 20:46:14 +0200 https://berthub.eu/articles/posts/encrypting-ip-addresses/ On IP address encryption: security analysis with respect for privacy Frequently, privacy concerns and regulations get in the way of security analysis. I’m a big fan of privacy, but I’m also a big fan of security and preventing people from getting hacked. If you are hacked you have no privacy either. Per-customer/subscriber traces are extremely useful for researching the security of networks. Specifically, lists of DNS requests per IP address make spotting infected users or infected devices very easy, especially if you look at “yesterday’s traffic” and compare it to today’s threat intelligence. https://berthub.eu/articles/posts/on-linux-vdso-and-clockgettime/ Fri, 24 Mar 2017 20:22:18 +0200 https://berthub.eu/articles/posts/on-linux-vdso-and-clockgettime/ On Linux vDSO and clock_gettime sometimes being slow Like the previous post on this somewhat dormant blog, I want to share an oddity I discovered that no search engine could really find for me - even though once I found what the problem was, it turns out I was by no means the first person to discover this. Some system calls that are used extremely frequently in Linux can be speeded up by a mechanism called vDSO: a virtual dynamically linked shared object. https://berthub.eu/articles/posts/optimizing-optimizing-400-percent-speedup/ Thu, 22 Sep 2016 13:16:31 +0100 https://berthub.eu/articles/posts/optimizing-optimizing-400-percent-speedup/ So no matter how pretty your code, eventually someone will benchmark it and demand top performance. Squeezing microseconds is a very addictive and even destructive activity. It ruins your evenings, destroys your ability to converse with human beings and typically leaves your code in a mess. No programmer can escape it however: the world demands speed, or a somewhat equivalent modern measure, longer battery life. Squeezing out more performance is not just a matter of “writing better code”. https://berthub.eu/articles/posts/how-about-some-actual-innovation/ Sun, 17 Apr 2016 20:45:41 +0200 https://berthub.eu/articles/posts/how-about-some-actual-innovation/ A meandering walk through innovation that also reviews a book This article is part of a series on (European) innovation and capabilities. I care deeply about innovation. It is literally where the future comes from, but it is a curious thing. Innovation and its more powerful partner, invention proceed at a snail’s pace. “In a world where change is the only constant” is a lie. It took this world 20 years to invent a decent can opener. https://berthub.eu/articles/posts/how-many-hours-for-multithreading/ Tue, 02 Sep 2014 20:25:58 +0200 https://berthub.eu/articles/posts/how-many-hours-for-multithreading/ How many hours for multithreading the server? Or: dealing with overly detailed project planning Many developers, me included, dread that moment. Someone sits down with you and wants to know how many “hours” each step of the project will take. And of course the thing is, if you are doing something that has been done many times before, you might be able to provide a detailed estimate. People that build houses work like this, but they still often get it wrong.
