Grok is many things but it is not "neutral". https://www.economist.com/briefing/2026/06/25/ai-models-valu...

People give them money because of the moral stance. They are either actively fine with the CSAM or just don't care.

The premise of this statement is wrong.

I realize as a Californian we may not count as "American" in this particular zeitgeist stereotype. But FWIW we have a firework ban in Nevada County that is widely respected. There are very few violations and the law is actively enforced.

The difference is we are in a no-joke dangerous fire situation and everyone recognizes it. Most people know better than to set off incendiary explosives in a forest. Anyone who shot off illegal fireworks would immediately be shamed and censured by their neighbors. I guess it's a form of commune-ism.

numerous vulnerabilities in secure boot deployment over many years. e.g. https://arstechnica.com/security/2024/09/secure-boot-neuteri...

I'm surprised more people aren't freaking out about this. It seems likely a whole lot of Linux machines are going to fail to reboot in the next few months. The problem affects VMs too. I was grateful Proxmox put a little warning in its hypervisor GUI with a button to press to fix the BIOS of its VMs.

Secure Boot has been deeply broken for years, not providing meaningful security on most consumer machines.

I love stuff like this. But if it's serious as a thing you might use, would be nice to see some example programs and evaluation of how well they work. Also a test suite.

If you like the idea of smart corvids, Adrian Tchaikovsky's scifi novel "The Children of Memory" is a fun read.

Backrest is so good as a frontend to Restic I stopped looking for anything better. Is there anything better now?

We once deleted the lost+found folder on an old Unix system* by accident. Things went very badly the next time the system rebooted, fsck did not handle it at all well.

* Probably DEC Ultrix 2.2, a BSD 4.2 derivative.

This is the classic Terry Moore 3 minute video. It boils down to "tie a square knot". It changed my life too!

I love this video because it's both the perfect TED video and the perfect parody of a TED video.

Is Start9 a well known company? The page by itself seems indistinguishable from a scam, but maybe they have a reputation that justifies their asking for $250,000?

I like TopoJSON and have used it in projects. But it's weird to set it up as opposition to GeoJSON. It's a complement. GeoJSON is a general data format meant to replace uses of ESRI Shapefiles and other complex formats. TopoJSON is more of a solution for a particular application need.

Is there much work developing or using TopoJSON these days? I haven't seen much about it in a few years.

This reminds me ChromeOS has some USB-C cable identification superpowers: https://www.reddit.com/r/UsbCHardware/comments/1pyojjd/comme...

Not sure if it's using the same thing this MacOS thing is doing. In the link the author explains that the cable e-Marker contains a "Discover Identity" message that you can read and display in ChromeOS. Most ordinary Windows hardware can't read it because of BIOS limitations, but Chromebooks can. I'm guessing Macs can too.

I keep hearing a lot of good buzz about their product. Haven't tried it myself but I mean to.

Most old-timers here are familiar with a Prolog-variant: make. Anyone who's struggled over a complex Makefile wishes they had a more sane declarative language!
