I don't hate FEE, but there's a lot of opinion in this article above and beyond the original source. Maybe link to that? https://www.mckinsey.com/industries/public-and-social-sector...

Given the author mentions multiple cores being available, I'd guess you could use any method, including MPI, to distribute the computation. But whether you used 1 core or 10k cores, it would be nice to have a 20x speedup on each core v

I don't know much about MPI, but I thought it related to message passing/distributed workloads rather than arithmetic performance?

The amount of effort and extra hardware required to maintain this reproducibility across different hardware (cpu generations, GPU hardware/drivers, etc) feels insane to me. For example, people seem extremely interested in performance,

If I recall, the zstd binary has a mode that is basically "adapt the compression ratio so that compression isn't the bottleneck", but I didn't have a chance to try it. Have you used that?

The parent article doesn't seem to be trying to be a fully fleshed out survey of compressors, but I found a separate comparison of zstd and Brotli: https://peazip.github.io/fast-compression-benchmark-brotli-z... tldr:

I understand cause of death statistics can be calculated, but do you have an article on what happened with a decapitation being counted as a covid death?

My understanding is that the Texas state requirements used to be borderline insane, but that they have improved over time. Skimming http://ritter.tea.state.tx.us/rules/tac/chapter113/index.htm... , I actually

There's no way to get the raw data from this site, is there? I have long been interested in doing some analysis of how syllabi have changed over time, but that doesn't seem possible with this interface.

(I have fairly minor quibbles with some of Nate's modeling ideas, but I broadly mean to be defending him). I don't mean to imply 2016 was a black swan event- I agree that ~30% was probably as accurate a take as could be achieved (

I don't think this article provides strong evidence that they are well calibrated on the presidential election specifically (sample size N=3), or that they are correctly accounting for rare black swan events, but it does seem to imply

LZ4 seems really nice for data with a lot of repetition, but not having any symbolic entropy encoder can really kill the compression for some data. I often default to LZ4, and used to fall back to gzip if that doesn't work well, but I&

So, the main result of designing a CPU is a series of masks that essentially indicate where to put what. For example, in this layer, inject boron anywhere the mask doesn't block. The masks aren't wafer sized- they are pretty small

How so? It seems like lots of businesses run successfully on that model for indefinite periods.

I may not have said it well, but I broadly agree with you. If a workload needs high performance but not consistently (e.g. because you're doing serial tests by swapping bitstreams), predictably (e.g. because you need flexibility for ne

Just to throw in one more complication, I'll assert that the only benefits of FPGAs over ASICs are one time costs and time to market. Those are big benefits, but almost by definition, they aren't as important for workloads that ar

I agree that's a really striking and suggestive result, but keep in mind the sub-sample size there is four passing on the private side and six failing on the public side. My guess is there's a real and meaningful effect there, but

I've wondered for a while- are there heuristics on the income a steamer can make per viewer-hour? Edit: I'd googled this before, but apparently I found the right way to ask: this site says from 1c to $1/hour/viewer. htt

Depending on your definition of cheap, fab access might be pretty cheap right now for old technology nodes, which have totally reasonable performance if you have an architectural advantage. This article suggests mask tapeout costs are under

I've not read Popper directly, so I'd be interested in his actual argument on this. But, I wonder if you can describe H1 as being a stronger hypothesis than H2 by virtue of withstanding more and higher quality attempts to disprove

I found the hash table lecture really interesting, somewhat practical, and it made me sound really smart when I got the inevitable hash table questions during interviews.

Is there data on what tech companies programmers (either generally or new grads) most want to work for? It feels like it used to be Google by a lot, but even outside the HN bubble, I get the sense Google has taken some reputation hit.

They say later that > When a feedback instrument surveys eight colleagues about your business acumen, your score of 3.79 is far greater a distortion than if it simply surveyed one person about you—the 3.79 number is all noise, no signal.
