Typically the other way around; ADTS is a way to get AAC within MPEG-TS through means of a wrapper. If you remux AAC from MPEG-TS (like e.g. a satellite feed) into MP4, it strips away the ADTS wrapper (and adds a single ASC header for the M

It authenticates the user to the service, but not the service to the user, so it's vulnerable to phishing (or MITM, of course, if you don't have TLS).

Good to know. Another possible question is: What is the best strategy minimizing (at any point) _first_ the maximum number of tries, and second the EV (average number of tries over all possible words)? That's subtly different from eith

You can get EV of 3.46393 with a guaranteed maximum of five tries. (I don't know whether this bound is tight.)

BitTorrent isn't particularly efficient; a well-designed CDN beats it every time, and is pretty cheap these days. (Generally, you get random peers, not peers that are particularly close to you. You could try to fix that, but you'd

Your #3 is very optimistic. You can't just remove a join (be it inner, left, or really any other type) just because you didn't refer to any fields from one of the sides, and it's even harder when aggregation is in the mix. Th

What if you do SELECT a + b, SUM(x) FROM t1? Should the implicit GROUP BY be on (a,b) or (a+b)?

Not by the SQL standard, since projection (which creates aliases) happens after aggregation. There are many databases that allow it as an extension, though.

Larger systems would usually use drive bays with 80-pin SCSI, which was the regular 68-pin SCSI, plus automated address configuration (ie., you got the address assigned to the bay), plus power, all in one connector.

The fact that CPUs internally have microcode doesn't mean there's a different RISC CPU lurking underneath that you could just take the lid off of. In particular, the instruction decoder, which is what you're proposing to chan

More specifically, most devices will want _4:2:0_ Y'CbCr. It's highly unlikely that FFmpeg gave you anything that's not Y'CbCr (H.264 can technically encode RGB, but I've never ever seen it in use). And if it choose

Thank you! It's becoming the default now, slowly (e.g., it will be the default in Debian and Ubuntu from the next releases, and Fedora is in a process to make it replace mlocate right now). It's just a tad too new, only about a ye

This isn't the same as the old Windows async I/O. ptrwis' links are what I thought of (and it's essentially a 1:1 copy of io_uring, as I understand it).

I've used sendfile + kTLS on Linux for a similar use case. It worked fine from the start, was broken in two (?) kernel releases for some use cases, and now works fine again from what I can tell. This is software kTLS, though; haven&#x2

This used to be the case, but with io_uring, Linux has very much non-broken buffered async I/O. (Windows has copied io_uring pretty much verbatim now, but that's a different story.)
