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.

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?!

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.

Intel's 386 processor (1985) moved the x86 architecture to 32 bits, but it needed to be backward compatible with earlier 16 and 8-bit processors. As a result, it needed complicated circuitry for its internal registers: six different circuits for 30 registers. Let's look at the silicon circuits. 1/N

Added a way to diff two assemblies at the byte level. This is what I really needed it for - to debug deterministic builds. I needed to see why is the assembly different even though nothing has changed. In this case it was SourceLink stamping the Git SHA into the embedded pdb.
