Hill climbing a password would only be possible if intermediate KV cache entries were stored. To hillclimb "hunter2", you're going to try "a", "b", "c", etc, until you notice that "h" c

I'm a little nervous about the correctness of the memory orderings in this project, e.g. Two acquires back to back are unnecessary here. In general, fetch_sub and fetch_add should give enough guarantees for this file in Relaxed. https

I'm not going to thumb my nose at CPU design content from folks that aren't good at public speaking. They're almost entirely distinct skill sets.

This comment is a nugget of gold - I hadn't thought about it in those terms before but it makes total sense. Thank you!

One of my favourite YouTubers, Matt Orchard, did a video on cults that included Heaven's Gate. He interviews a surviving member. If this article interested you, it's worth a watch (the beginning is a bit silly): https:/&#x2F

OpenAI automatically caches prompt prefixes on the API. Caching an infrequently changing internally controlled system prompt is trivial by comparison.

See Tokio's Loom as an example: https://github.com/tokio-rs/loom In development, you import Loom's mutex. In production, you import a regular mutex. This of course has zero overhead, but the simulation testin

This is a misreading of their website. On the left, they compare the EPYC 9965 (launched 10/10/24) with the Xeon Platinum 8280 (launched Q2 '19) and make a TCO argument for replacing outdated Intel servers with AMD. On the

But humans do quite intelligently pathfind around objects they're aware of, and update their mental models with new information. The front door is locked? I'll go around the back. You can achieve exactly what you're describ

I'm curious where the line is if you represent yourself in a criminal case. At what point (if any) would opening up Google Docs and typing notes about the case that inadvertantly incriminates yourself become inadmissible?

Thanks for expanding, I was misunderstanding the point you were trying to make with the example.

I haven't participated in this thread yet, but I would like to drill down on your TSan example. It seems to me that the window of timing for TSan to catch it is _super_ tight, as the overhead of creating a thread is very large relative

This is such a great book, especially the section on operating system primitives, which made the book wider in scope and more practical. After all, you're probably not building exotic data structures by hand in memory without also need

Well, my question would be whether retail minus 6% would be the prevailing rate in a free market with healthy competition, or is it a subsidy? I'm not against subsidies. Germany pushing solar well before it made financial sense, enabli

It's not an outright contradiction, just an explanation of why I doubt their claim. I am not myself making a claim. Given that they are correcting a "common misconception", I think it's entirely appropriate to ask for a

Do you have a source for "The grid fees solar owners pay account for that"? If you look into e.g. PG&E's financials, their expenses are dominated by operation and maintenance of the grid, not what they pay for electricity

That makes sense to me! Experienced developers are probably better off targeting WASM with Rust, but an easy on ramp to programming is definitely something that can justify a new language.

Yes. I've made a dozen games using rollback and it really is magical. I built a strategy game in three weeks and didn't test it in multiplayer until the weekend of release. It Just Worked. But it's not a total silver bullet f

(the) Gnorp Apologue is written in Rust and did pretty well: https://store.steampowered.com/app/1473350/the_Gnorp_Apologu... And for something like Gnorp, Rust is probably a decent choice.

I wouldn't expect much either. The potential for speedups would be if there's locality for data on either side of the multiplayer padding, or if the actors have contiguous layout and deleting the data plays better with the CPU&#x2

There's a sweet spot for running MoE models, though. If you need the entire model in VRAM but only need to retrieve a part of it per token, trading more memory for less bandwidth can be a win. I have a 4090, and given the MoE trend, I&

Depending on a bunch of factors of how this data is accessed and actors are laid out in memory, it may be more cache friendly which could yield substantial speedups. Or it could do next to nothing, as the data is multiple cache lines long a

Troy Teslike claims this also includes the $35/kWh tax credit linked below, which would be a substantial boost. I'm not in a position to verify and Troy's content is behind a Patron paywall, so make of that what you will. Thi

You're extrapolating Pinto rear end collision fire deaths to overall collision fire deaths using the standard ratios of the time. But the Pinto was prone to rear end collisions causing fires. So the correct ratio is unknown, and presum

The scenario is that the 512gb M3 Ultra was validated for the Mac Studio, and in volume production for their servers, but a business decision was made to not offer more than a 256gb SKU for Mac Studio. I don't think this happened, but

Chip? Yes. Product? Not necessarily... It's not completely out of the question that the 512gb version of M3 Ultra was built for their internal Apple silicon servers powering Private Compute Cloud, but not intended for consumer release,

This guide is absolutely fantastic, thank you! You should post it if it hasn't been.
