Evidence that NVIDIA has even been trying? My understanding is that Apple didn’t allow 3rd parties to write graphics drivers past 10.13, but they could’ve done a non-graphics driver like this.

I believe it was the first RISC that Apple prototyped building a Mac around, including a 68K emulator. IIRC from Gary Davidian’s CHM oral history, it was corporate dealmaking that led to AIM and PPC more than any technical negatives for the 88K.

The report says it broke when updating from macOS 15 to 26, so not a minor patch update. I'm a bit surprised no one noticed this earlier though, since 26 has been out since September and in beta since June.

AppleScript doesn’t have any NeXT heritage, it comes entirely from classic MacOS (debuted in System 7.1)

This leak has been floating around for years, and it's not even close to everything (i.e. no GUI pieces)

Apple is shipping code built with this, and is supporting it for developers to use (see https://developer.apple.com/documentation/xcode/enabling-enh...)

CarPlay supports that, the car just needs to pass it through. I believe Ford and Toyota both do.

The original article is here, and it unfortunately is just as confusing: https://www.reuters.com/business/intel-ceo-says-company-will...

Of course Intel has been designing and selling GPUs for years, I guess Lip-Bu means they're going to start manufacturing them as well? Or they're going to be data-center focused now?

Are you talking about Starliner? Starliner's 2 flights have been problematic to say the least, but Orion's single (uncrewed) flight went pretty well.

Various anticheat/DRM schemes actually do direct syscalls on Windows, so Proton has patches that use seccomp to trap them and jump to the intended Nt* syscall. There was actually a feature added to the Linux kernel a few years ago (syscall user dispatch) so that Wine could stop using seccomp for this, but Wine is still not using it.

Upstream Wine also supports direct syscalls on x86_64 macOS. macOS syscall numbers have a high bit set, so Windows syscall numbers (0 to ~300) are invalid macOS syscalls, that triggers SIGSYS, and then Wine jumps to the Nt* syscall.

How are they explaining away the fact that the Japanese male astronaut asked for a consult with the flight surgeon on the public loop (a video which NASA has since removed from YouTube)?

Everyone on the ISS needs to have a seat reserved for them in a docked spacecraft, in case they need to evacuate the station quickly (or for a medical issue like this). You can’t bring back just one person from a 4-person crew; the other 3 would have no way to leave.

The stapled ticket is optional beyond notarization itself. If you notarize but don’t staple the ticket, users may need an internet connection to check the notarization status.

IMO, the benefits of an immutable OS install outweigh being able to uninstall/remove particular apps.

I don’t believe it’s been years, only the latest firmware version for the ELAC is affected. The fix is to downgrade (or replace hardware with a unit running earlier firmware)

mrpippy — Mon, 24 Nov 2025 21:31:20 +0000

One thing I like about using OpenBSD for my home router is almost all the necessary daemons being developed and included with the OS. DHCPv4 server/client, DHCPv6 client, IPv6 RA server, NTP, and of course SSH are all impeccably documented, use consistent config file formats/command-line arg styles, and are privilege-separated with pledge.

UPS and FedEx each have around 25 MD-11s, Western Global has 2 I think, the Orbis Flying Eye Hospital is an MD-10, some cargo airline in Botswana has one, and 10 Tanker has some DC-10 firefighting tankers.

That’s the entire worldwide fleet.
