It is 2026 and glibc's longjmp still doesn't execute finalizers when truncating the stack.

@firefox.com is a great PDF reader. It can sync the TOC and navigate hyperlinks just fine. It can deal with the Arm ARM's 102 MiB file much better than Adobe's own reader which is a resource hog and is always trying to sell you something.

Q: "Hey Siri, what is the driving distance between Tacoma and Kirkland both in Washington". A: "I need to know your location. Please enable Siri access to location on your settings app."

So... why do you need my current location to answer that question?

.NET Lab can now display disassembled machine code. It's taken directly from JIT, hence only supported on desktop for now. #dotnet #csharp #roslyn #asm #dotnetlab

Good news. In VS 2026 Preview /Oy- is now the default, even in the "Release" configuration. This is the case at least for new projects. Glad to see this finally fixed.

In case you had missed it - I had. VirtualBox now supports Windows on Arm.

Not a bad alternative to the departed Windows Services for Android.

Now this is something unexpected: Tahoe's new "Apps" pannel behaves worse than Windows start menu. It is sluggish, at times downright unrespinsive, some UI elements just don't work... it is me or "26" is just not Apple's number?!

macOS Tahoe (download) is 20GB. Geez!

Please, debug card manufacturers: Stop using micro-USB for UART ports. Just stop it. Really! No more. Please! There is this thing called USB-C now - been here for a while. Pretty solid. Give micro-USB honorable fairwell. Please!

When there are all adults in an adult setting it is weird to ask where the "potty" is. You ask for the "bathroom", or some other adult word for it. Same goes for an engineer to say "BSOD". The word is "Bugcheck".

Here is my updated TF-A + EDK2 for QEMU. It enables running Windows and Hypervisor under TCG. The package includes my startup script plus a sample OS image. Use with QEMU 10.1.0. With this you can do everything I demoed on the Linaro Connect keynote. 1drv.ms/u/c/a075d439...

Preview of Xbox App finally fully functional on Arm64, allowing you to download and install purchased or subscribed games. Yes, most will be running under emulation and there will be glitches. But this is how we erode chick-and-egg adoption resistance to Arm64
