mrpippy··on NTSB Preliminary Report – UPS Boeing MD-11F Crash [pdf]
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.

mrpippy··on Apple will phase out Rosetta 2 in macOS 28
Rosetta for PPC apps was supported from the first Intel Macs released in January 2006 until 10.7 Lion was released in July 2011.
mrpippy··on Apple will phase out Rosetta 2 in macOS 28
The OP only applies to Rosetta for running x64 Mac apps, not running x64 Linux software in aarch64 Linux VMs.

mrpippy··on VMware's in court again. Customer relationships rarely go this wrong
Yes, but just try to download it from them. You have to make an account, agree to all kinds of garbage, and then you still might be stuck in "authorization" like my account is. They removed the auto-update functionality (even the notification!) from the app, so you have to manually go through their horrendous website to download updates.

It's 10x easier to just search reddit or internet archive for a link to the .dmg.

mrpippy··on The future of 32-bit support in the kernel
With watchOS 26, S9/10 watches will be going to normal ILP64 ARM64.

RAM limitations were one reason to use arm64_32, but a bigger reason is that the first watches were only ARMv7 (32-bit) so by sticking with 32-bit pointers, Apple was able to statically recompile all the 3rd party (ARMv7) apps from LLVM bitcode to arm64_32.

mrpippy··on John Carmack's arguments against building a custom XR OS at Meta
My understanding is that this is a key tenant of visionOS’s design, where apps don’t get access to gaze data (I think unless they’re taking over the full screen?)
mrpippy··on Zed for Windows: What's Taking So Long?
> Vulkan runs on Windows, and quite well.

Not everywhere. See the middle bug report, "Zed does not work in Remote Desktop session on windows" (https://github.com/zed-industries/zed/issues/26692).

Most Remote Desktop/Terminal Services environments won't have any Vulkan devices available, unless you ship your own software rendererer (like SwiftShader).

Also, NVIDIA only supports Vulkan on Kepler (GTX 600 series), AMD on GCN 1.0 (Radeon HD 7000 series), and most importantly, Intel on Skylake (6000 series). Especially on the Intel side, there are plenty of old but still-supported Windows 10 machines that lack Vulkan support. For many applications that's ok, but IMO not for a text editor.

mrpippy··on Blender is Native on Windows 11 on Arm
Apple has supported that ‘-arch’ option in their GCC/Clang since at least the PPC->Intel transition, maybe even earlier (PPC64? NeXT/OPENSTEP?)
mrpippy··on The Linux Kernel Seeing Rare Code Activity Around SPARC64
Running Linux? And up-to-date kernels?

Even if no one’s using it, it’s ok for the kernel to be supported and improved.

mrpippy··on Electric cars produce far less brake dust pollution than combustion-engine cars
Some EVs allow different levels of regenerative braking to be selected. The Hyundai/Kia E-GMP-based cars have level 0-3 plus a 1-pedal mode, and also an "auto" mode that slows down more based on radar proximity to the car ahead.
mrpippy··on Vintage Macintosh Programming Book Library (2017)
The home page has full collections of Inside Macintosh and “New” Inside Macintosh: https://vintageapple.org/

I would also love to see an archive of MacTech, their own web site has a pretty full archive but I always fear it’ll fall offline.

mrpippy··on How Tesla is proving doubters right on why its robotaxi service cannot scale
It says 42 minutes via subway because you have to walk to the station and wait a few minutes for the next subway. Plus if you were driving, you’d of course need to park at the destination (either expensive or time-consuming, possibly both).
mrpippy··on How Tesla is proving doubters right on why its robotaxi service cannot scale
If it’s parked on the street, that is taking up a lane that could be carrying traffic. (And in some cities it’s common for parallel street parking to turn into a lane from 4-8 PM or similar)
mrpippy··on How Tesla is proving doubters right on why its robotaxi service cannot scale
How about the World Trade Center to Yankee Stadium. Driving is 32 min with a $9 toll, or 38 min with no toll. Subway is 31 min with $3 fare.

And this is a Sunday afternoon, I’m sure the drive gets dramatically worse on a weekday.

mrpippy··on A Tour of Microsoft's Mac Lab (2006)
In Redmond?

I seem to remember MacBU was in San Jose, maybe that was before this post? Or were things split between the locations?

mrpippy··on Final report on Alaska Airlines Flight 1282 in-flight exit door plug separation
> Given their nature the original intent was probably that they were secured at the factory and never touched

Specifically in this case, that factory being Spirit Aerosystems in Wichita where the 737 fuselage is manufactured. Part of the problem here is that Boeing in Renton didn't have processes for removing the MED when necessary on the final assembly line (in this case to rework rivets near the door). Without processes, there was one senior guy on the door team who taught himself how to do it, this was only needed a few times a year, but he was on vacation when this airframe needed the MED removed. Someone else did it (the NTSB couldn't determine who), the work wasn't tracked, and a separate team (the team literally sealing it up so it could be moved outside) put the MED back in but didn't install the bolts (which were gone).

mrpippy··on Reverse Engineering the Microchip CLB
It's baffling, I don't consider this a production-usable feature if the toolchain is only available remotely on a Microchip server.
mrpippy··on Snow - Classic Macintosh emulator
The Griffin iMate was the most popular ADB-USB adapter from the time, and probably supports non-input devices (it would’ve been the only option at the time to make those dongles work).
mrpippy··on Finding a 27-year-old easter egg in the Power Mac G3 ROM
Note that this was the last “OldWorld” Mac (at least desktop Mac, the WallStreet PowerBook G3 was probably a bit later) where the traditional Mac ROM was in an actual hardware ROM.

“NewWorld” started with the iMac: only Open Firmware was in ROM and the classic Mac OS ROM was just a file on disk.

When a HW/SW team is shipping a new Mac and burning a ROM, that feels like an occasion to put in a picture of the team. When you’re not burning a ROM and the picture would take up space on everyone’s disk…not so much.

mrpippy··on I convinced HP's board to buy Palm and watched them kill it
The same day they shut down WebOS, all the unsold hardware was cut to fire-sale prices. TouchPad was $99, and they sold out everywhere at that price.

I bought 2 at the time, sold one and used the other for a while. The hardware didn't feel as nice as the iPad 2, but it was serviceable. The software was neat and the card metaphor arguably is still more sensible than iOS/iPadOS of today. I can't see any way that HP could've been more than a distant 3rd place behind iOS/Android, but it would've been fun to see them try.

mrpippy··on macOS Tahoe brings a new disk image format
Apple recently made FSKit a supported/documented API, which should allow third-parties to add support for other filesystems: https://developer.apple.com/documentation/fskit?language=obj...
mrpippy··on Container: Apple's Linux-Container Runtime
VMware Fusion is a perfectly good way of running VMs, and IMO has a better and more native UI than any other solution (Parallels, UTM, etc)
mrpippy··on The Windows Subsystem for Linux is now open source
Note that this doesn't include lxcore.sys, the kernel side driver that powers WSL 1.

(Also, I'm surprised that WSL 1 is still supported. It must be in maintenance mode though, right?)
