Engineers are pretty jaded about plans expressed by authority, especially when there are obvious pressures opposing those plans. Yearly planning doesn't matter when a reorg will change the trajectory by Q3. Sprint planning doesn't

Every time I've rewritten a major project I've made it smaller and faster while fixing all the major bugs and most of the minor ones. My current team has had similar experiences. I'd be curious to see what a Zig -> Zig rew

Not just beeping. I had a rental Nissan recently violently pull me straight off the road when it couldn't read the lines very well in a thick fog. Apparently you can disable that deep in some settings menu through some magic button pre

I remember an engineer I talked to recently saying that OSM didn't have sufficiently up-to-date data for their routing use case -- new roads, closed roads, traffic data, etc. Is that the case?

Potentially lots of money, potentially none, but they should be honest about the capabilities and lifetimes of their products and not make that profit through bait-and-switch and other lies.

I've found my calling. Is this "Tim" role open now that he's left?

Interesting. I can barely stay awake in typical commercial planes, and I always attributed it to the lower partial oxygen pressure.

That makes sense to me. There's a causal link between ambient air CO2 levels and cognitive changes, but the air in front of your face, which you breathe, doesn't play a role... A lack of direct study might make "in front of y

For complicated problems, you can't just write the language spec. You need to iteratively develop it, which itself requires some intermediate state/language describing what you know so far. That intermediate state being the end pr

It makes more sense when you view sandboxing as enabling project correctness in the presence of skilled, fallible maintainers rather than preventing explicit attacks. Solutions for the former do a lot to thwart attacks from the latter, but

Sure, it's changing, and I use AI a ton. The second I ask it (where "it" is a smattering of all the SOTA models and harnesses) to do something as simple as design a server capable of doing <moderately simple task> when

And who can't code its way out of a wet paper bag on hard problems. It's more productive for the day-to-day BS, which is convenient because it creates more day-to-day BS you need to handle, but that isn't the reason I hire a

Whatever we're moving toward, I currently can't let any SOTA model + harness operate on more than ~10k changed SLOC at once, and even then only with very careful prompting I thoroughly understand, only on the simplest of problems,

You could even just have straight proportional voting if you wanted, and that's be better than the current system. You got 3 votes? Great, you have a 3/100M chance to win.

The Bitcoin argument is usually paired with "there are no non-scam use cases which aren't better served by other methods/tech."

Batching order, as you mentioned, matters a lot, and for any heavily optimized kernels it will change from one machine to the next. You also have the choice of backend numerical library from, e.g., different OS versions. There are floating-

With breaks, and it's also normal that in a class of ~30 you'll still find a couple students with cramps.

Many good students don't produce such artifacts. That's one of the big problems in academia -- a smart person with good ideas can inadvertently pursue a less promising path and not produce ground-breaking research, so how do you t

I'm all for handwritten tests, but it's more complicated than that. If you're actually writing for 2hr+ and haven't studied appropriate technique or bought some sort of crutch like a pencil holder then the repetitive mot

My initial implementation used [9][9]u9 (which desugars to [9][9]u16 with some zero bits) and was a fair bit slower. If I had to guess, it's because the shift/extract/align you're describing isn't actually a part of

I'm probably not the only culprit then :) I'd be curious to know who else has done things like that.

At most the second from me, and last time I didn't talk about the project (haven't talked about the project online at all IIRC).

Old habits :) If I had to steel-man the idea, I'm pretty sure the integer-based solution has better codegen with many kinds of sparse, comptime-known masks. I think you're right though, StaticBitSet looks better.

I used it for awhile for "prod" for a toy project. I was scraping nearly every sale across every Target location for awhile. It was fast and easy to use. At the time many (read) queries had bugs of various kinds, requiring strange

IIRC, for "normal" bit widths the codegen basically uses the next larger machine type and preserves zero bits on the high end. An i3 is an i8 with five MSB zeroes (with more custom behavior for "packed" i3 values). It&#x
