New comment by gliptic in "Rust--: Rust without the borrow checker"

gliptic — Thu, 01 Jan 2026 12:51:19 +0000

The borrow checker doesn't decide when things are dropped. It only checks reference uses and doesn't generate any code. This will work exactly the same as long as your program doesn't violate any borrowing rules.

Camping is like.. regulatory capture? Stretching the analogy thin here.

But that fine-tuning is done only on those 100-200 good samples. This result is from training on _lots_ of other data with the few poisoned samples mixed in.

This doesn't really make sense to me. Most cats I've known react to such reflections without ever having seen a laser pointer in their life, for the same reason they react to laser pointers.

Glyph advance or line spacing is not part of the bitmaps.

The names are much less flashy, Draken (The kite, due to the shape) and Viggen (The tufted duck) :P.

`f(++i, ++i)` is/was indeed UB, but the example in munificent's comment was `foo(print(1), print(2))` which as far as I know is not even if both `print` calls read/write the same memory.

Yes, but that's just a subset of expressions where unspecified sequencing applied. For instance, the example with two `print()` as parameters would have a sequence point (in pre-C++11 terminology) separating any reads/writes inside the `print` due to the function calls. It would never be UB even though the order in which the prints are called is still unspecified.

The author is using the term in the way that everyone else understands it. They are not aware of your unusual definition.

The evaluation order is _unspecified_, not undefined behaviour.

New comment by gliptic in "Zig, the Ideal C Replacement Or?"

gliptic — Sun, 11 May 2025 17:02:30 +0000

It's really not. Looks like something like JS with almost identical syntax.

Also, the compiler (and what else?) isn't even implemented [1].

Ah, FastML is an extremely overloaded name.

It's strange that someone from FastML can be confused about this, unless it's supposed to be a bad joke.

New comment by gliptic in "Query Engines: Push vs. Pull (2021)"

gliptic — Thu, 17 Apr 2025 10:36:20 +0000

I'm not seeing how this is pull in any sense. Calling recv on the channel doesn't cause any result to be computed. The push of the previous operators will cause the compution to continue.

EDIT: Ok, I guess because they are bounded to 1, the spcs will let the pushing computation continue first after the "puller" has read the result, but it's more like pushing with back-pressure.

For pixelation you can use another technique invented for astronomy: drizzling [1].

I guess it will be a bigger issue the longer it's been since they stopped making them, but most I've heard (including me) haven't had any issue. Crypto rigs don't necessarily break GPUs faster because they care about power consumption and run the cards at a pretty even temperature. What probably breaks first is the fans. You might also have to open the card up and repaste/repad them to keep the cooling under control.
