There was a time when version control was an exotic idea. Today, things like Git and a handful of other tools allow developers to easily rewind the clock or work on different versions of the same thing with very little effort. I’m here to encourage you not only to use version control but also to […]
Every time we end up talking about 3D printers, Al Williams starts off on how bad he is in a machine shop. I’m absolutely sure that he’s exaggerating, but the gist is that he’s much happier to work on stuff in CAD and let the machine take care of the precision and fine physical details. […]
Dan Maloney and I were talking on the podcast about his memories of the old electronics magazines, and how they had some gonzo projects in them. One, a DIY picture phone from the 1980s, was a monster build of a hundred ICs that also required you to own a TV camera. At that time, the […]
It was probably Montesquieu who coined the proto-hacker motto “the best is the mortal enemy of the good”. He was talking about compromises in drafting national constitutions for nascent democracies, of course, but I’ll admit that I do hear his voice when I’m in get-it-done mode and start cutting corners on a project. A working […]
This week, the hackerverse was full of “vibe coding”. If you’re not caught up on your AI buzzwords, this is the catchy name coined by [Andrej Karpathy] that refers to basically just YOLOing it with AI coding assistants. It’s the AI-fueled version of typing in what you want to StackOverflow and picking the top answers. […]
Earlier this year, I bought one of those K40-style laser machines that was listed at a ridiculously low price, and it arrived broken. Well, let me qualify that: the laser tube and the power supply work perfectly, but that’s about the best you can say about it. On first power-up, it made a horrible noise, […]
Is a bicycle like a motorcycle? Of course, the answer is it is and it isn’t. Saying something is “like” something else presupposes a lot of hidden assumptions. In the category “things with two wheels,” we have a winner. In the category “things that require gasoline,” not so much. We’ve noticed before that news stories […]
We ran a story about a wall-mounted plotter bot this week, Mural. It’s a simple, but very well implemented, take on a theme that we’ve seen over and over again in various forms. Two lines, or in this case timing belts, hang the bot on a wall, and two motors drive it around. Maybe a […]
to everything that plagues this world beset by the Unspeakable Horror that is the C programming language. As the latest entry to pledge its fealty at the altar of the Church of the Holy Memory Safety, TrapC promises to fix C, while also lambasting Rust for allowing that terrible unsafe keyword. Of course, since this […]
In our wider community we are all familiar with the idea of open source software. Many of us run it as our everyday tools, a lot of us release our work under an open source licence, and we have a pretty good idea of the merits of one such document over another. A piece of […]
