The best kind of Hackaday posts are the ones where there was some insurmountable problem with an elegant solution devised through deep analysis of the problem and creativity. This is not one of those posts. I’m sure you are familiar with bit rot. You know, something works for a long time and then, for no […]
One of the delights in Bash, zsh, or whichever shell tickles your fancy in your OSS distribution of choice, is the ease of which you can use scripts. These can be shell scripts, or use the Perl, Python or another interpreter, as defined by the shebang (#!) at the beginning of the script. This signature […]
Meet the little board that could: [alcor6502]’s tiny USB relay controller, now evolved into a multifunction marvel. Originally built as a simple USB relay to probe the boundaries of JLCPCB’s production chops, it has become a compact utility belt for any hacker’s desk drawer. Not only has [alcor6502] actually built the thing, he even provided […]
We’ve seen a Linux-based operating system made to run on some widely varying pieces of hardware over the years, but [Dimity Grinberg]’s latest project may be one of the most unusual. It’s a PCB with 3 integrated circuits on it which doesn’t seem too interesting at first, but what makes it special is that all […]
If you spend a lot of time at the command line, you probably have either a very basic prompt or a complex, information-dense prompt. If you are in the former camp, or you just want to improve your shell prompt, have a look at Starship. It works on the most common shells on most operating […]
Shell scripting is an often forgotten programming environment, relegated to simple automation tasks and little else. In fact, it’s possible to achieve much more complex tasks in the shell. As an example, here’s [calebccf] with an emulated 6502 system in a busybox ash shell script. What’s in the emulator? A simple 6502 system with RAM, […]
You can argue if bash is a good programming language or not, but you can’t argue that it is a programming language. However, there are a few oddities about it that make it different from most other languages you probably know. For one thing, variables are dynamically scoped. Second, you can easily change variables in […]
What do you do when you need to choose an OS at boot but aren’t physically near your machine? [Dakhnod]’s inventive solution is a mix of GRUB, Wake-on-LAN (WOL), and a lightweight ESP8266 running a simple HTTP server. In the past, [dakhnod] already enlightened us with another smart ESP hack. This one’s a clever combination […]
It is a common problem: I have a USB device on a computer out in the shop, and I want to use it from the comfort of my office. What to do? Well, you could remote desktop into the distant machine. But, honestly, I always find any remote desktop more than ssh clunky and somewhat […]
