Your periodic reminder that Borland released the sourcecode to Turbo Vision under an open source license, and then someone added Linux, Windows and Unicode support to it, so you can use it to write modern applications

German politician Nico Semsrott has suggested that we give billionaires one year to solve the climate crisis. If they fail to do so, we should dispossess them. I think that’s a wonderful idea! It's never going to happen, but it's nice to dream.

Watching webassembly.github.io/spec/cor load in and realizing with fridge horror that somebody made a web page by just writing TeX into a .html file and then onLoad running a JavaScript that re-interprets the tex into HTML

@uint8_t @whitequark I have done that a few times, and with all the deadlines you have to set and the evidence you have to collect for them to do anything it’s really more of a bother than I’m willing to deal with 🫠

@whitequark I've also been unsuccessfully trying for like a year now to unsubscribe from their newsletter that they put me on without consent.

@whitequark I asked nxp for a datasheet for one of their imx parts a while ago using my university address, and they told me to fuck off because they considered that datasheet too secret for a pleb like me. I wasn't very impressed by that stance.

have been playing with cellular automatons and generating pretty patterns again, will probably post more about the software tomorrow or so, for now enjoy these pretty outputs :3

They all have a border and an imperfection to the top left, from where a different, maze or plant like pattern emerges into the squares.a chaotic and mesmerizing array of three by three patterns of lines in a colour, almost heatmap alike gradient from red to blue via white-yellowa chaotic and almost trippy image of a mazelike structure with circular rings and belts. its colours range from red to marine blue, light green, purple to a light brown in the backgrounda vertical striped pattern of red and white-red bands with an imperfect but repetitive border. the whole image is structured like a maze

In Saudi Arabia 'disobedient' women are incarcerated for rehabilitation.... This is inhumane & a violation of human rights.

But, of course, 150 years ago we were doing something similar with early mental hospitals & other institutions aimed at 'caring' for 'hysterical' women.

This is in no way to defend the contemporary practice, but more to point out its hardly unprecedented in the annals of violence to women.

Women have fought this fight before!

@katrinatransfem Oof, ty. to me re-wrapping text is basic text editing 😅

I'm trying out vscode atm. Do you really, unironically have to install an extension for it to be able to re-wrap a paragraph to a given width or am I missing something?

@drj @cato it’s an add-on, the machine also has a treadle. Both the motor and the machine are branded Singer though. I imagine the motor was maybe designed later, or in a different branch of the company. I can’t tell if the motor was bought together with the machine or added later.

2025-05-27

@cato My headcanon is that the sewing machine was made in a retooled tank factory given that it was made in the early 1950ies in western Germany and for some reason is made entirely from cast iron, weighing in at almost 20kg

2025-05-27

@drj Tbh once I’ve grounded the thing I don’t think it’s more of a hazard than something new. Worst case, a fuse pops. I certainly wouldn’t call it a “death trap” at that point.

Compared to modern devices, I think an insulation failure is less likely here since they used triple-insulated wires everywhere with two layers of woven natural fiber insulation and a plastic outer sheath. Where modern cables melt, these fibers would need 250C or so to carbonize instead, and I’m sure you’d smell that.

2025-05-27

@cato It’s so funny because the sewing machine itself is built like an actual tank, and is a joy to do maintenance on. I get the vibe that it and the motor were not designed by the same people.

I’ll replace its mains input with a hardwired C13 socket. I’ll also replace the filter caps with new ones. Even though they are still okay, I had an old filter cap blow up on me before and I found that experience scary and stinky enough. I’ll hardwire the lamp into the power input instead of using the socket on the motor because it needs a new cable anyway, and I can use that opportunity to ground its currently ungrounded metal case.

2025-05-27

The electrical design of that motor is sooo sketchy by modern standards. While the motor’s case is grounded, they used an ungrounded mains lead meaning any insulation failure would energize the whole sewing machine. The motor’s brush assembly is simultaneously a power socket for the sewing machine’s lamp, with the connecting wires just crammed in between the brushes.
