They first published the Armv8-M ASL around 2017. I suspect you've believed that this didn't exist due to the predominance of pre-Armv8-M devices in the market: there is no ASL for Armv7-M and earlier, and devices based on these o

Looks as though ARM is doing ASL for Armv8-M. "For example, the ASL code published through the A-Profile Arm Architecture Reference Manual, Exploration Tools downloads for A-Profile, or the Armv8-M Architecture Reference Manual."

Another auto spinning globe with no way to turn that off. At this point I'm convinced all these globe apps are copying the same examples from somewhere and inheriting the same gimmick.

Among policy and security people, the term they bandy about is Advanced Persistent Threat (APT). They're not wrong; there are a number of recent cases, and these are ongoing, and you've heard of some of them: Volt, Flax and Salt

It there some law that mandates all 3D globe renderings auto rotate and omit any way to stop it?

Sharp MIP makes every pixel an SRAM bit: near-zero current and no refresh necessary. The full color moral equivalent of Sharp MIP would be 3 DACs per pixel. TFT (à la LG Oxide) is closer to DRAM, except the charge level isn't just hi

The PCWorld story is trash and completely omits the key point of the new display technology, which is right in the name: "Oxide." LG has a new low-leakage thin-film transistor[1] for the display backplane. Simply, this means each

5 has this. There are modules that get you to function signatures and type constraints. It's all opt-in and, as was said, you have to nudge LLMs to use it, but they can and the results are indeed better.
