Another notch on the wall as we've reached the esteemed age of 18 years in the cURL project. 9 releases were shipped since our last birthday and we managed to fix no less than a total of 457 bugs in that time. On this single day in history... 20,000 persons will be visiting the web … Continue reading curl is 18 years…
If you are looking to synthesize the sound of a plucked string, there is an amazingly simple algorithm for doing so called the Karplus-Strong Algorithm. Give it a listen: KarplusStrong.wav Here it …
For the past few years I’ve followed the evolution of Rust with interest. Rust is a new systems programming language (like C or C++) with greater emphasis on...
Note: Thanks for all the great comments and feedback here and on Hacker News . Please keep them coming. I learned a ton and I am sure others will also.
This site will be the main location for information about the LLVM backend for Scala that is under development by Geoff Reedy.
Update! I tested more hash functions in a follow-up post. See More Hash Function Tests .
As part of an ongoing attempt to learn more about how a real-life Garbage Collector (GC) works (see part 1) and after being inspired by Julia Evans’ excellent post gzip + poetry = awesome I spent a some time writing a tool to enable a live visualisation of the .NET GC in action.
Last time we looked at generating random dungeons for video games using the Drunkard’s Walk algorithm. The Drunkard’s Walk is fun to play with, and often generates cool levels, but it’s also pretty unreliable. That’s not good enough for my purposes: I want to reliably generate big, open, cave-like maps, with lots of…
Last week, Peter and I gave a tutorial at SciPy 2016. In keeping with our recent thinking about reproducibility and organization , the idea was to look at how some of the hard-won lessons and best practices from modern software engineering can be applied to data science work.

In this article I want to talk about negative aspects of the programming community, regarding beginner programmers. This is a touchy topic. I will try to explain both sides to the best of my ability, but I’m not endorsing either side. My only hope is that some readers will gain more empathy for the people they are…
There's a network-server programming pattern which is so popular that it's the canonical approach towards writing network servers:

This is a cautionary tale. One of youth and a lesson I eventually learned but still often don’t heed. About how sometimes, the tool that is easiest to get started with isn’t the tool that will make your job the easiest.
One of the things I love about Lisp is that it gives you the ability to change and mold the syntax of the language to what you need. In this post I want to look at the evolution of a little macro I've been playing around with for a while now.
I wanted to know how a modern C compiler like clang would process the following C code: #include <stdint.h> int count(uint64_t x) { int v = 0; while(x != 0) { x &= x - 1; v++; } return v; } Can you guess? popcntq %rdi, %rax That is right. A fairly sophisticated C function, … Continue reading The surprising cleverness…

It’s common knowledge that reflection in .NET is slow, but why is that the case? This post aims to figure that out by looking at what reflection does under-the-hood.
