My pet peeve is that grub repartitions windows disks on chain load, so if it ever boots with the disks remapped, there's a chance it'll plow apart the partition table of whatever poor disk got mapped to that hd#.

Long enough ago I don't remember the business details. The 4.x compiler line never being patched was a bit of eye opener into commercial toolchain support.

I was still learning assembly, it took me a while to be sure it wasn't my bug.

You're eactly right. I saw the blight at Herculaneum, MO in the 2000s - dozers plowing down houses in a slowly expanding circle centered on the smelter. 1 in 5 students had excess blood lead. The schools nearby were scraped down and so

MIPS on GCC defaulted to trapping integer overflows, but they had non trapping instructions too.

Takes many bit flips to go from one pattern to another.

That's more the scale I was thinking .You'd still need a rechargeable battery or large cap to run the ESP32 in any useful mode.

100 microwatts - I can't imagine a phone idles on that. About 36 microamps at 3.6 volts. > less than a coin at 15 x 15 x 5mm Slightly smaller than a stack of four US dimes.

You can use a Windows build on wine.

Agreed. Where it mattered for me was on an ARM core managing a much larger DSP. The DSP consumed most of the memory bandwidth, so fetching a cacheline of instructions or an MMU mapping into the ARM had long and variable latency as it had to

Rarely if ever. This isn't about tail-calling, it's about function placement in the final image to enable branch elimination. There's no call between foo and foo0, but many of the requirements for a tail call are also require

Another GPU friendly approach is mixing with blue noise. I used it in a display driver with XRGB8888 framebuffer and Y2 pixels, and it worked great.

Excel. Conditionally format based on constrain violations and difference from target baudrate. Brute force and scroll.

This reminds me of guessing codepoint likelihood based on character distribution.

It was, in the old days, 16-bit, IIRC.
