Another possibility at least in the case of lots of network sockets is DPDK, avoiding almost all the context switches if the user side is async.

If I want a small keyboard I want it with a built in pointing device, and those are hard to find. Lenovo trackpoint keyboard is one of the few I can think of.

Interesting, I might make sure to brush teeth and gargle before going out in a mask. When I say I've gotten sick from walking with a mask, I don't mean "felt sick", I mean I've literally gotten respiratory infectio

Nobody else has trouble walking strenuously with a face mask on? I'm fine with the mask while standing around or short periods of not too vigorous walking, but with any sustained exertion it gets stifling, and after a little while it

Common carriers are regulated entities like shipping companies and telecoms. You get to be one through a huge amount of bureaucracy, negotiation with regulators, etc. It protects you from a lot of liability but also creates a lot of const

How many times are they going to repeat the search phrases like "one billion lines"? It's reached the point where SEO obstructs human readability. It was cool that Object Pascal (maybe a descendant of Turbo Pascal) compiled

Yes, you fail over to a hot mirror, or if you really have to rebuild because something went nuts, do it from a recent snapshot.

I think SIMD referred to Intel SSE*/AVX/etc., where the vectors are of fixed length. That meant new instructions had to keep getting introduced for new sizes of vectors.

60% of murder cases result in someone getting arrested. So we still have to ask: a) how many of those arrests result in a conviction? b) how many of those convictions are of the right person? c) and how many murders result in murder case

It's nice that e-paper has suddenly gotten a lot more affordable. I wonder what the cause of that is--did important patents recently expire, or anything like that? Still, it is most interesting in larger sizes, preferably full A4 for

The PIOs are much smaller and less powerful/flexible than the PRU. The PRUs are 200 mhz 32-bit cpus with DSP-like capabilities and 8k of memory (partly shared with the application cpu). They can directly access the analog ports too.

> 90mA in full-speed run mode. Keep in mind that's at maybe 2 volts rather than 5 volts. Still, it's 360uA per MHz, counting the two 125MHz M0+ cores as 250MHz total. That's pretty power hungry compared to other Cortex M

It actually sounds sort of difficult on those PIOs. All the timing stuff, start and stop bits, parity, flow control, ideally a FIFO, etc. You only have 32 words of instruction memory in each PIO. I wish they had made the PIOs more capabl

You are supposed to fit-test N95's. They sell some kind of mint spray for the purpose. If your N95 is on properly, you aren't supposed to be able to smell the mint. Covid virus particles are about 0.125 micron, so it's not

If you mean the online quiz, that is a screening funnel for the video interview, which (as of some years ago, don't know about now) was fairly involved. The online quiz itself wasn't difficult if you knew what you were doing, but

An interesting piece of advice that I saw in another HN thread about good company behaviours stuck with me over the years. When someone unsubscribes from your mailing list, delete their email address from your database. Don't retain
