Java doesn't produce 'garbage data', racing writes will never show intermediary results.

Sorry, I don't see it that way.

Why should we care about the COSMIC Desktop Environment? Edit: I've now gotten 2 downvotes in 4 minutes. I do not understand what's so controversial about this comment. Why should we care about having a third DE? Does this matter

Intel Arc Pro B60 will come in a 48GB dual-GPU model. So yeah, hardware is gonna be there, and the 24GB model will be $599 from Sparkle. I assume 48GB will be cheaper than a hacked RTX 4090. Look at this: https://www.maxsun.com&#

I don't think it counts as visiting, as you never look at the dirtied bitmap during GC, only during allocation. That means, you don't actually know if a dirty bit represents a different object or not (if a 16-byte size class is al

I forgot that this GC is non-moving (I'm not used to that assumption, and it was a bit of a quick comment). I do find the statement dubious still, do you mind clearing it up for me? Given a page { void* addr; size_t size; size_t alignm

To add on top of this: This is a tracing GC. It only ever visits the live data, not the dead data. In other words, it would need a lot more special support if it wanted to report the dead objects.

I'm not sure what the goal was here, that's not what I'm saying.

I'll do the opposite: The P vs NP episode is aboslutely horrid. Probably the first and last time that they had any informatics people on the show. One major issue is that the experts didn't explain what we mean by "hard"

Same, Emacs is improving at a rapid rate thanks to its adoption of LSP and Tree-Sitter. Performance is very good, but the async story needs to become better.

Let's not over correct, of course O-notation has something do with algorithms for the working programmer.

Good job on dispelling the myth of "compiler = fast". I hope SPython will be able to transfer some of its ideas to CPython with time.

That was quite rude of Andrew. If someone doesn't want to review a PR, then they should just ignore it IMHO.

I think you answered how you managed to induce latency in Emacs :).
49.
by writebetterc 1y ago
It's surprisingly slow. Switching files in the tab list has a noticeable delay. Typing is higher latency than both Emacs (lsp-mode activated) and my web browser. Also uses approximately 60MiB more than my Emacs. It starts fast though!

FWIW, I've heard from people who know this stuff that linking is actually super slow for us :). I also wanted to try out mold, but I couldn't manage to get it to work.

>10 minutes for linking? The only projects I've touched which have had those kinds of link times have been behemoths like Chromium. That must absolutely suck to work with. I don't know the exact amounts of time per phase, but y

Multi-tenancy on the JVM makes me shudder, though. The general point you're making, thumbs up to that.

Ownership and lifetimes are arguably not about Rust, but about how we construct programs today. Big, interdependent, object graphs are not a good way of constructing programs in Rust or C++.

You don't need to learn how git works internally to be able to use it. You need to know a lot about filesystems in order to use them: Folders, files, symbolic links, copy, cut, paste, how folders can exist on different devices, etc. Th

Yes, Rust is better. Implicit numeric conversion is terrible. However, don't use atoi if you're writing C++ :-). The STL has conversion functions that will throw, so separate problem.

It's a bit annoying that there is a standard desugaring of all of this, but there's no actual way of implementing this sugaring yourself. I guess you could have a token macro (or whatever they're called) at the top scope and
