On this page I present a robust, custom build system for a software project written in C, in less than 500 lines of Python code. I think it is about as minimal as a practical dependency-tracking build system can get. Although it adds to the code that must be maintained as part of the project, I think that having a…
If you want to make a sound shorter, you can play it faster. Doing this also makes it higher pitch unfortunately. If you want to make a sound longer, you can play it more slowly. This also makes it…
Postgres stores a lot of statistics about your data in order to effectively retrieve results when you query your database. Here we deep dive into some of the statistics PostgreSQL stores and how you can leverage a new feature in Postgres 10 to improve performance when different columns are related.
Context A few years after I created the Elastic Binary Trees (ebtree) , I started to get some feedback from users who needed to use the...
In this article I shall discuss several game programming techniques, all revolving around a central theme: the sine and cosine functions. This article will explain sine, cosine, vectors, atan2, and some useful special effects such as how to make homing missiles and how bitmap rotation works. I shall start with the…
Before we dive into the technical details, let’s start with a quick history lesson, courtesy of Don Syme who worked on adding generics to .NET and then went on to design and implement F#, which is a pretty impressive set of achievements!!

While in the middle of writing “Reading bits in far too many ways, part 3”, I realized that I had written a lot of background material that had absolutely nothing to do with bit I/O and…
The Apple Macintosh combined brilliant design in hardware and in software. The drawing program MacPaint, which was released with the computer in January of 1984, was an example of that brilliance both in what it did, and in how it was implemented.
How to script in any language thanks to rootless containers and BINFMT_MISC.
Having benefited from “var” for many years when writing c#, I’m delighted that Java is at last getting support for local variable type inference in JDK 10. From JDK 10 instead of saying ArrayList<String> foo = new ArrayList<String>(); we can say var foo = new ArrayList<String>(); and the type of “foo” is inferred as…
Laziness is often useful. It allows you to express “infinite” computations, and only pay for as much of the computation as you need.
The details of running a complex ticket ranking site for under a dollar a month on AWS
It should come as no surprise to anyone who reads this blog that I love to program "by hand." I happen to practice a degree of ascetical programming practices, and I believe that they help me to more deeply internalize and understand problems, ultimately delivering higher quality solutions. One of

A few years ago I started to work on an MPEG1 Video decoder, completely written in JavaScript. Now, I finally found the time to clean up the library, improve its performance, make it more error resilient and modular and add an MP2 Audio decoder and MPEG-TS demuxer. This makes this library not just an MPEG decoder, but…
I work on a lot of Javascript projects. The fashion in Javascript is to use build tools like Gulp or Webpack that are written and configured in Javascript. I want to talk about the merits of Make.
Today, as part of Mobile World Congress 2018, we are excited to announce the first beta release of Flutter . Flutter is Google's new mobile UI framework that helps developers craft high-quality native interfaces for both iOS and Android. Get started today at flutter.io to build beautiful native apps in record time.
The goal of the numpy exercises is to serve as a reference as well as to get you to apply numpy beyond the basics. The questions are of 4 levels of difficulties with L1 being the easiest to L4 being the hardest.
In the immortal words of Ricky Bobby, I wanna go fast [https://www.youtube.com/watch?v=_qJGsSuFRIg]. When I launched Pwned Passwords V2 last week [https://www.troyhunt.com/ive-just-launched-pwned-passwords-version-2/], I made it fast - real fast - and I want to talk briefly here
Most programmers agree that we don't read enough code. The interviews in Peter Seibel's book, “Coders at work” highlight a comical contradiction: almost all the programmers interviewed by Seibel recommend that others read code for fun, but none of them routinely do so themselves. Seibel even asked Hal Abelson (of SICP…
