It is well known that pictographic languages that use Hanzi, like Mandarin, are difficult to work with for computer input and output devices. After all, each character is a tiny picture that represents an entire word, not just a sound. But did you ever wonder how China used telegraphy? We’ll admit, we had not thought […]
Raspberry Pi clusters have been a favorite project of homelabbers and distributed computing enthusiasts since the platform first launched over a decade ago, and for good reason. For an extremely low price this hardware makes it possible to experiment with parallel computing — something that otherwise isn’t easily accessible without lots of time, money, and […]
[Juan] describes himself as a software engineer, a lover of absurd humor, and, among other things, a player of Nethack. We think he should add computer game archaeologist to that list. In the 1990s, he played a game that had first appeared on USENET in 1987. Initially called “Middle-earth multiplayer game,” it was soon rebranded […]
There are many applications out there that use more than one window, with every modern-day platform and GUI toolkit offering the means for said application to position each of its windows exactly where it wants, and to restore these exactly in the configuration and location where the user saved it for that particular session. All […]
Over on the [Behind The Code with Gerry] YouTube channel our hacker [Gerry] shows us how to emulate a 74LS48 BCD-to-7-segment decoder/driver using an Altera CPLD Logic Chip From 1998. This is very much a das blinkenlights kind of project. The goal is to get a 7-segment display to count from 0 to 9, and […]
[Samcervantes] wanted a cyberdeck. Specifically, he wanted a Clockwork Pi uConsole, but didn’t want to wait three months for it. There are plenty of DIY options, but many of them are difficult to build. So [Sam] did the logical thing: he designed his own. The Bumble Berry Pi is the result. The design criteria? A […]
If you’re familiar with electrical slip rings as found in motors and the like you’ll know them as robust assemblies using carefully chosen alloys and sintered brushes, able to take the load at high RPM for a long time. But not all slip ring applications need this performance. For something requiring a lot less rotational […]
