- Help, my sin() is slow and my FPU is inaccurate
- C++ books I recommend (37000 views so far!)
- PowerDNS.com, my big open source project.
- Some notes on floating point programming with UNIX and Linux
- HOWTO use SIMD (SSE, SSE2, SSE3, 3DNow!, MMX) instructions with gcc.
- Linux 2.4 Advanced Routing & Traffic Shaping HOWTO
- Getting Linux 2.6 to work on a Dell Latitude
- Dreambox satellite receiver, some perhaps useful

Rusty). Futexes are high performance
locking primitives in the 2.6 kernel.
- How to get the linenumber from a linux kernel oops
- Linux Logical Volume Management HOWTO (unmaintained)
- Lex & YACC HOWTO
- Some evil ideas about
decentralised loadbalancing/clustering, with no single point of failure
- Beginnings of an rrdtool HOWTO (unfinished, but
- At one point, I got all fired up about synchronous webservices
- dnsdist - a highly DNS-, DoS- and abuse-aware loadbalancer. Its goal in life is to route traffic to the best server, delivering top performance to legitimate users while shunting or blocking abusive traffic.
- Weakforced - The goal of 'wforced' is to detect brute forcing of passwords across many servers, services and instances, all with flexible policies to support the real world.
- Splitpipe, a tool to spread the
output of, say, tar over multiple volumes (DVDs, CDs, hard disks etc).
- Tool to display your logical volumes (unmaintained)
- Tool to display 'cachedness' of files: cinfo.
FreeBSD, recent OpenBSD, Linux, Solaris
- The Wonder Shaper for lag-less
uploading & downloading over ADSL/Cablemodem
mail receiver & popserver
- MTasker, very simple cooperative multitasking in C++
for people, like me, who are not smart enough for state machines
- vmloader, tool to load a virtual memory system in
various ways and report stats. Unmaintained, but might be useful
