Database Protocols Are Underwhelming
If you’ve been in this trade for a while, you have probably seen dozens of debates on the merits and problems of SQL as a relational database query language. As an ORM maintainer, I have a few gripes with SQL, but overall it is workable, and anyway, it has so much inertia that there’s no point fantasizing about a…

A System-Witch’s Package Manager Murder Mystery
It was a calm day on the puppy-linux thinkpad. The CPU was cool, the RAM was operating at double data rate, and a gentle breeze flowed through the chassis as the fan whirred away.

Speeding up the Rust edit-build-run cycle
There are two main aspects to compile times that matter to developers. Cold build times, when building from scratch and warm build times when you’ve already built and you’re rebuilding following an edit. This article focuses on warm build times, which for rapid iteration during development is what generally matters…

Serving a half billion requests per day with Rust and CGI
In my previous post Serving 200 million requests per day with a cgi-bin, I did some quick performance testing of CGI using a program written in Go. Go works excellently for CGI programs, for many of the same reasons it works so well for CLI programs and system daemons. But, out of curiosity, I decided to do a bit more…

In this article I describe the DEFLATE algorithm that GZIP implements and depends on. The DEFLATE algorithm uses a combination of LZ77, Huffman codes and run-length-encoding; this article describes each in detail by walking through an example and developing source code to implement the algorithm. My aim is to…
