Not the author but: `GetKeyState` and `LoadMenuA` are going to stand out in the disassembly. Backtracking from `GetKeyState` is how I found a devmode in "warhammer: shadow of the horned rat". Though it is activated by a boring com

_Daily_ hit pieces on Elon Musk (or Musk companies), going for something like a decade. These have petered out somewhat since he left DOGE. But they started way back before he should have had that much notoriety.

`_mm_alignr_epi8` is a compile-time known shuffle that gets optimized well by LLVM [1]. If you need the exact behavior of `pshufb` you can use asm or the llvm intrinsic [2]. iirc, I once got the compiler to emit a `pshufb` for a runtime shu

Alcoa (Aluminum Smelter, *cheap electricity*) was the major industry in the area. Massena plant now produces 85% less aluminum compared to ~15 years ago (AFAICT), leading to something of a ghost town (and cheap housing).

Limited internet connections (speed and/or data-caps). Something like Hughesnet (satellite ISP) couldn't stream more than 240p from youtube during peek times. The data-cap coerced users to do downloads between 2am to 6am.

> “regular” rejection sampling I was thinking naive: mask off unwanted bits then reject any value above the limit. It would seem like https://c-faq.com/lib/randrange.html would also move the multiply --or divide by

A optimized version would use 64-bit accumulators (`psadbw` on SSE2, or some sort of horizontal adds on NEON). The `255` max constraint is pointless. Many programming languages/frameworks expose this operation as `reduce()`.

Why not use regular rejection sampling when `limit` is known at compile-time. Does fastrange[1] have fewer rejections due to any excess random bits[2]? [1] https://github.com/lemire/fastrange [2] https://git

That snippet would not reject bad chars, are non-digits rejected somewhere else? A simple scalar loop that multiplies an accumulator by 10, itoa() style, would be faster.

The methods in those articles could be slightly improved by picking better multipliers. https://stackoverflow.com/a/71594769

There are two digits for months. A check is required per-character to prevent bad chars (e.g 0x3A) from being laundered by the multiply. The '19' comes from fact that the first digit may be only 0 or 1, while the 2nd digit maybe a

The AVX2 version is using a 8 KiB table...? Even the range check is inefficient. I'd bet that the AVX2 version could be 50% faster.
