• Delicious meta thought from this morning: The table pounding from the AI-skeptical software engineers, shouting "they can't build proper, scalable, performant programs!", sounds especially thin when you consider that right now nearly everyone is looking for where this is going and no one knows yet. Building something "proper" and "scalable" and "performant" before you have PMF is a tricky thing to pull off (there's exceptions, of course, where PMF comes from being one of the three) and now it seems like most companies are looking for PMF every 3 months.

Computer science professor who works on fast data processing; co-author of the simdjson parser and a weekly blogger about software performance since 2004.

• If anyone wants a nice side project... The fast number parsing fast_float (part of GCC, and other important systems like MySQL) is not always exact when dealing with 16-bit float parsing (specifically float16_t). That is, some number strings can lie in between two numbers and the rounding is wrong. In fact, nobody has done a proper analysis of the implementation to insure that it is correct. Yeah. I could ask my AI, but it is still work, especially because I do not trust anyone, not even an AI, to get it correct the first time around. Contributions invited.

It is not a claim that the year gone by was sweet. It is a decision that the year ahead should be. And I know that the year behind us has been anything but. Two Jewish m…

• Sound like many employees at Anthropic share Jacob's POV, as many posted yesterday that (1) they agree, and (2) said that many more inside the company do also. It would be useful to name this "belief system" so that we can talk about it in a reasonable way. I suspect "doomer" seems derogatory, and "accelerationist" has others uses. If there a word we can use so that we can have proper discourse? I'm very serious. I think it would be helpful.

• I have some news. But first a little backstory. Almost exactly four years ago, I drove down to Mountain View for my first day as a Google employee. I was fifty-four years old, and somehow had managed to avoid ever having a proper job over that entire period, other than a few startups that I had founded in my twenties and thirties. At that point Google Labs, which had just been formed a few months earlier, was headquartered in a fairly anonymous looking suburban office park off 101, closer to Office Space than Silicon Valley on the Mike Judge spectrum. And as it happened, my first day at Googl…

• A while ago, @regehr was tooting about optimizing brainfuck, and I speculated that peeling off the first iteration of a loop might make the loop body easier to optimize: https://mastodon.social/@nelhage/113241955294210125 Today I learned that RPython/PyPy use a very similar idea to support loop optimizations in their trace optimizer: https://dl.acm.org/doi/epdf/10.1145/2480360.2384586 By peeling off a single loop iteration, the optimizer can "see" that the body proper is dominated by the first iteration, and specialize much harder.
