In support of software packages that come in the form of a single binary executable (statically linked or portable), that one can just copy anywhere in `${PATH}` and execute, without needing `sudo`, or downloading half the distribution's packages as dependencies.
The Guardian is one of my favorite news sources. I’m a subscriber (support news organizations!) and I read it daily. But it is not immune to errors, as this headline shows:68 °F above average is a …
As projects get more complicated the tooling has to improve. Outgrowing the arduino-ide is easy on the Pi Pico with the excelent pico-sdk but what if things get even more complicated...
WebGPU is a new graphics and compute API designed on the grounds of W3C organization (mostly) by the browser vendors. It’s designed for the Web, used by Java...
If you are a Rust developer you have most likely celebrated the news that the version 1.64 released on 22/09/2022 is 10-20% faster on…
Recently, I came across a function that checks whether an array is sorted, i.e. if there is no element which would be greater than its successor. Below is a sample implementation:
1500 bytes is a bit out there as numbers go, or at least it seems that way if you touch computers for a living. It’s not a power of two or anywhere close, it’s suspiciously base-ten-round, and computers don’t care all that much about base ten, so how did we get here?
See how well you know (or can anticipate) gcc's optimizer. For each question, the left box contains some code, while the right box contains code that purports to do the same thing, but that illustrates a particular optimization. Will gcc apply that optimization? Put another way, will the code on the left be as fast as…
An introduction to a new post series covering debugger basics.
I never understood how traceroute discovers each hop. Turns out it's a clever TTL trick, and about 80 lines of Rust.
My first computer was a BBC Micro. It could do basic graphics at a resolution of 640×256 - with 8 different colours. Not a typo. Eight! The mono speaker produced bleeps and bloops. It was basic, in all senses of the word. Eventually, talented hackers found a way for it to do simplistic 3D graphics and even speech…
You'd think that given the same bytes of input you'd get the same bytes of output. lol. lmao. No, you don't. It's complicated.

To be able to investigate and work on the the measured boot features I have switched from grub to systemd-boot (sd-boot).
I want to say a few words about my current adventure. I joined the Fuchsia project at its inception and worked on the daunting task of buil...
6-5-0-who? The 6502 is an iconic processor that dominated home computing in the late 70s and early to mid 80s. It was used in machines ra...
I’ve been a maintainer of asdf for about 6 years now. Most of my work these last several years has been fixing bugs, writing automated tests …
Otherwise known as “wait, you mean I can use the TLA toolbox from the command line?”
So, you’ve got a program that’s using more and more over time as it runs. Probably you can immediately identify this as a likely symptom of a memory leak. But when we say “memory leak”, what do we actually mean? In my experience, apparent memory leaks divide into three broad categories, each with somewhat different…
A friend cleaned up and gave me a copy of a game I've not heard about before: Castrol Honda Superbike World Champions , a motorbike racing game for PC, released 1998 by Interactive Entertainment Ltd. and Midas Interactive Entertainment.
The source code of Doom3 has been released three days ago :) ! I have started to read it and I will probably write a code review if enough people are interested. According to the README.txt the source code is building well with Visual Studio 2010 but it is not building at all on Mac OS X with XCode 4.0 ( it is…
