When you used punch cards or tape to write a computer program, brief variable names were the norm. Your compiler or assembler probably only allowed six letters, anyway. But times change, and people who, by habit, give array indices variable names like I, J, or K get a lot of grief. But [Jack Kelly] points […]
Last year’s Supercon, we’ve had the pleasure of hosting Thea [Stargirl] Flowers, who told us about her KiCanvas project, with its trials, its tribulations, and its triumphs. KiCanvas brings interactive display of KiCad boards and schematics into your browser, letting you embed your PCB’s information right into your blog post or online documentation. Give the […]
A few days ago the source code for the popular Winamp music player was released into the world, with as we reported at the time, a licence that left a lot to be desired. Since then it seems some of the criticism has caught up with the company, for not only have they modified their […]
Have you wanted to get into GPU programming with CUDA but found the usual textbooks and guides a bit too intense? Well, help is at hand in the form of a series of increasingly difficult programming ‘puzzles’ created by [Sasha Rush]. The first part of the simplification is to utilise the excellent NUMBA python JIT […]
The 1990s seem to have reached that point at which they are once more considered cool, and ephemera of the decade has become sought-after. One of the unlikely software hits from the period was Winamp, the MP3 player of choice in an era when time spent on dodgy file sharing sites or peer to peer […]
[John Calhoun] was digging around their old MAC hard drives, revisiting some abandoned shareware games they wrote over three decades ago, and has uploaded the recovered disk images to GitHub for everyone to take apart and play with. This repository has a few of the games complete with their development files and the compiler environment, […]
The open-source parametric 3D modelling software, FreeCAD, is out in a release candidate for version 1.0. If you’ve tried FreeCAD before and found a few showstoppers, it might be a good time for you to test it out again because the two biggest of them have been solved in this latest version. First, version 1.0 […]
Lisp is one of those programming languages that seems to keep taunting us for not learning it properly. It is still used for teaching functional languages today. [Adam McDaniel] has an obvious fondness for this fifty-year-old language and has used it in several projects, including their own shell, Dune. Dune is a shell designed for […]
One of the most universal experiences of any Linux or Unix user is working through a guide or handbook and coming across an almost unbelievably complex line of code meant to be executed with a shell. At the time of encountering a snippet like this it’s difficult to imagine any human ever having written it […]
It seems like only yesterday we covered a project using QR codes to archive data on paper (OK, it was last Thursday), so here’s another way to do it, this time with a dedicated codec using the full page. Optar or OPTical ARchiver is a project capable of squeezing a whopping 200 Kb of data […]
