I wish ChatGPT could have told the author about the existence of mtr before starting this :-)

CSS animations run in the compositor thread, so they are isolated from jank due to concurrently running JS.

Yes, if you have special Ubnt-brand cables. And still, I want this to be standard everywhere, not a niche thing from one manufacturer :-) (I know Facebook has some on their 100G switches, too.)

Well, again, different problem constraints, different solutions. Seemingly that tool can handle larger sets than gperf (although it claims gperf stops at a couple hundred, which is an exaggeration; try it with the first 1000 lines of /

I never really finished the project, thus only the rough qualitative benchmarks you get at the bottom (measured mostly by profiling and size(1)); I saw that it wasn't enough of a win in the larger context where I needed it, thus it mad

They overlap, but none does strictly more than the other. Kaitai is for describing, encoding and decoding file formats. Wuffs is for decoding images (which includes decoding certain file formats). Kaitai is multi-language, Wuffs compiles to

What databases are those? If you convert to a semijoin, both strategies should be doable. Note that these caveats do _not_ apply to IN, only NOT IN.

I thought so, too, but I checked my IRC logs and it was discussed in 2012–2015 but never before that.

FWIW, you don't need to run forwards and backwards to get linear phase. Any symmetric FIR filter will do.

Yes, I would certainly prefer if you could write SELECT * FROM t1 SEMIJOIN t2 USING (x); although it creates some extra problems for the join optimizer.
225.
by Sesse__ 1y ago
I'm going to assume here that we're talking about a subquery here (SELECT * FROM t1 WHERE x NOT IN ( SELECT x FROM t2 )). If you're just talking about a static list, then the basic problem is the amount of data you get back.
226.
by Sesse__ 1y ago
What do you mean? Here are your real alternatives for doing a semijoin (assuming ANSI SQL, no vendor extensions): SELECT * FROM t1 WHERE EXISTS ( SELECT * FROM t2 WHERE t2.x = t1.x ); SELECT * FROM t1 WHERE x IN ( SELECT x FROM t2 );
227.
by Sesse__ 1y ago
The less verbose way of doing semijoins is by an IN subquery.
228.
by Sesse__ 1y ago
Or just doesn't know how to do semijoins in SQL, since they don't follow the same syntax as normal joins for whatever historical reason.

There were actually some completely insane workarounds even before shaders. I don't think it was actually shipped in real software, but I saw something that used 11 or 18 passes or something to do dot3 texture blending even on unextend

And even then, you couldn't really get any sort of serious matmul out of it; they were per-vertex, not per-pixel. Per-pixel matmul (which is what you really need for anything resembling GPGPU) came with Shader Model 2.0, circa 2002; Ra

Shadow DOM v0 was removed from Chromium in 2019 (with a lot of pain involved).

They are not allowed to loop or recurse, so no, by themselves, they are not (unless you accept repeating the function a potentially infinite amount of time). CSS in general is Turing complete if you allow running multiple frames, although i

You want CSS transitions or animations, since they can run on the compositor thread (most of the time). Zero jank. (I work with CSS browser performance, although animations is not my primary field)

Yes, but not performantly so. In particular, out-of-order delivery is likely to be seen as packet loss, signalling TCP to reduce the transfer speed in one way or the other.

You're starting them in order and you're ending (retiring) them in order, but you're not necessarily ending one instruction before you're starting the next one. For instance, in a very simple pipeline, you can start deco

by Sesse__ 1y ago
It is very rare that a single TCP connection will be load-balanced over multiple interfaces, since that would frequently cause out-of-order delivery, which sucks quite a lot if the receiver isn't prepared for it.

Huh, do typical Linux keyboards not have it on AltGr-L?
238.
by Sesse__ 1y ago
My biggest disappointment with MPTCP was that seemingly, you need both the old and new address to be available when doing handover. So you cannot suspend your laptop, go to a different place, and resume the TCP sessions on the new Wi-Fi.

Many Linux distributions provide en_DK specifically for this purpose. English as it is used in Denmark. :-)

It's the exact same phenomenon. :-) The high frequencies are abruptly cut off in both cases.
