Depending on board support you might get actual error correction or not. If it doesn't boot, it's very likely that you actually bought registered memory, which is normal in servers, but _not_ supported at all by Ryzen processors,

Unless we're talking extremes (AVX512...), optimizing for power in modern CPUs is almost always optimizing the race to idle. I.e. the CPU doesn't use much less power if most ALUs are idle, so you might as well use all of them to c

If I'm reading Figure 5 ("Fraction of clients reached by each message.") correctly, in a simulated "neighborhood network" with 50 users, broadcast messages reach less than 50% of users?!

There are Sigma cameras with a Foveon sensor that can do it: https://en.wikipedia.org/wiki/Foveon_X3_sensor Though they're not as good in most other dimensions as conventional Bayer filter sensors (most Amazon rev

The doc in question ( https://archive.org/details/frontline-workers-testimonies-va... ) contains anecdotes mixed with blatant lies about vaccine side effects. I totally agree that moderation can be overreaching, but this

On the contrary: a large number of the "poor" have ~zero or negative net worth, so inflation (unless extreme) doesn't affect them negatively.

And indeed, clang is able to do it for unsigned, too: https://godbolt.org/z/36r1Maq7b gcc doesn't seem to implement this optimization at all. Technically it should be possible for the <=n case, too: An infinite

The issue here isn't hardware capabilities, it's that vendors like to make their gadgets centrally connected for convenience and analytics and then on top often don't care about hygiene (e.g. no crypto at all).

The nrf52840 has a reasonable programming interface, good power consumption and can be bought as a USB breakout dongle for 10$.

Did you try again? Takeout is pretty flaky sometimes... especially with large libraries.

What's up with this meme that Google stopped full quality downloads? I've seen it mentioned in several places, but it doesn't seem true? I compared checksums of (recently uploaded) 1) original source images 2) result of click

It's a bit annoying for restore since it can take hours to be ready for download. Still better than Amazon Glacier though :D

The cloud is a backup. Just like any other backup you should test restore or at least verify the data regularly. I trust Google more than a random hard drive (to not lose random bits) in this respect. And unless your admin configured it awa

Doesn't "GPLv2 or later" specifically allow you to fork into "GPLv2 only"? How can a license be incompatible with only the latter then?

Compared to what? Taking rand()%n? Of course they're usually slower than that, because they provide better quality distribution of random numbers.

The generator/seeding design is gnarly, totally agreed. I do want to disagree with the author on distributions. In most scenarios it is totally sufficient for distributions to be deterministic and reproducible on a given implementation

You'd compare them to Xeon D (which are more comparable in terms of power/intended usage), so e.g. for top of the line 16 core models, the EPYC Embedded 3451 vs. the Xeon D-2183IT, with 64 vs. 32 PCIe 3.0 lanes.

I'm building a NAS right now. The Epyc 3000 parts looked appealing, but it's ~impossible to get them in Switzerland (and hard in Germany). While getting an Atom/Xeon-D board is relatively easy and there's a lot more choi
