What's a react compiler? Not JS or TS?

New comment by BretonForearm in "Memory Ordering in CPUs"

Would be useful for the article to start with a word on what memory ordering is.

Edit: it means, (re)ordering of memory access operations esp. when multiple execution units (cores) operate in parallel. Weakly ordered (ARM, RISC-V): if Core 1 writes Memory 1 then Memory 2, but for some reason writing into Memory 2 is quicker, then Core 2 may see Memory2 written before Memory 1 is written. While strong ordering (x86) retains the original order.

Why not let people try it from abroad? Not in the USA? No luck. Why does the withdrawal rate need to be a multiple of 0.5%? It's curious that the highest chance was associated with the highest (100%) stock ratio.

There is no "user case", it's called use case.

It hasn't ever been "A.I.". N.Y.Times looks sooo ancient.

Spaghetti length is made visible (quickly comparable), but it's still not sorted.

Bad website. No photo, only a video, and that wants to start with an ad.

Going from "SVG/Canvas is wasteful" to a tile based approach is a giant leap. Wouldn't AI suggest delta encoding of polyline coordinates and discretization of deltas as small, maybe just 2-4 bit integers? Storing the X and Y delta vectors separately, rather than interleaved, could lead to a further increase to the compression ratio.

What was asked of Claude? The article is very sparse on this.

Cool project!

Please consider another data source, or fixing this one. Crimea is part of Ukraine. Only Belarus, North Korea and of course the invading Russia think there's an international border there. I reject promoting that camp.

There should be no line between Crimea and the rest of Ukraine. Crimea is an internationally recognized part of Ukraine, not some other country.

I don't think so.

So Claude Code was used to generate software that ran simulations? I don't think LLMs in and of themselves can execute simulations, esp. a specific, non-single digit count like 100k.

It's the only correct take, since the title atop literally says "parasitoids on bread bag tags".

I bet the first viewers of VHS were busier with marveling at color, compactness and convenience instead of thinking of the new medium as something ugly and nasty. New technology that gets very popular usually starts as state of the art and impressive, and it's only in retrospect that people think of it in condescending way.
