You're referring specifically to tracing garbage collection. When a reference count reaches zero, that garbage is collected, often recursively. Among programming language designers, ARC is considered a GC strategy. https://e

It's even more fatiguing to see so many comments about whether something is LLM-written or human-written. I hope we get past this stage, soon.

So someone used lower() from an unspecified version of Unicode when the standard was very specific about which to use. And they say "There's also a database of Unicode 3.2.0 data available on every version of Python (unicodedata.u

Refcounting is indeed a form of GC (and the languages that want to handle cycles then need an extra form of GC on top of it).

Regular expressions aren't an algorithm. DFA/NFA-based matching and backtracking are both valid implementation strategies, with different performance characteristics. Backtracking is arguably the most intuitive direct implementati

So, on a news discussion site, active discussion gets penalised. There really should be a human in the loop on that one.

In common usage, "regex" means patterns accepted by regex engines like PCRE. Police the formal term "regular expression" if you like, but ordinary usage does not honour that distinction. Also, it's not guaranteed th

Every optimisation like this increases the chance of other optimisations/vectorisations being able to usefully fire, and sometimes these very specific cases are themselves from optimisations or type/range restrictions.

Do you posit that there are enough examples of 30x8 ellipses encoded in braille online for ChatGPT to learn from but not 31x7 or 31x9 ellipses? That seems unlikely.

They lost me a little before then - Claude Code's regressions were so very obvious and there's no sign they've learned their lesson in this article or in the comments of those who work on Claude Code on HN. They'll conti

In the video in question, he doesn't seem able to choose a good scoring function for the stochastic solver (even over multiple weeks), seemingly choosing a linear sum of distances (see 8:50) between simulation and reality. That's

Partly, it's simply that words matter. An interpreter is not a compiler, even if partial evaluators and Futamura transforms are very cool. Posting about them in a context that isn't a confusion about what interpreters are may have

Yes, that's another great example of the same kind of thing - creating a JIT from an interpreter. It remains true that interpreters do not directly generate machine code.
15.
by ghusbands 5mo ago
That's a partial evaluator, not an interpreter, and it converts an interpreter into compiler, which are different things.

by ghusbands 5mo ago
This is still incorrect. A bytecode interpreter, as its name indicates, interprets a bytecode. Typically, compiling a bytecode to native machine code is the work of a JIT compiler.

I wonder why most of the "g" characters are cropped.

True, but that’s using “effects” in a broader sense than people seem to mean here. The discussion seems to be about the visible effects the audience experiences as effects, and whether those age well, not invisible digital cleanup, composit

Even with high effort, the adaptive thinking can just choose no thinking. See bcherny's post they were replying to: https://news.ycombinator.com/item?id=47668520

Steganography is (hopefully invisibly) hiding information in an image, not creating an image that so obviously encodes information.

A common misconception is that git works with diffs as a primary representation of patches, and that's the implied reading of "stores diffs". Yes, git uses diffs as an optimisation for storage but the underlying model is alwa

Yes, once you use 'unsafe' to bypass the safety model, you don't get safety. Edit: If you reply with a reply, rather than edits, you don't get such confusion.

The comments on this site (HN) may be what most people are talking about. Youtube comments are too easily censored, so they probably will never manage to stick around.

I would probably see text quality issues on that setup. It depends on how far away the monitor is. PPI on phone screens tends to be much higher than PPI on laptops which tends to be higher than PPI on monitors, because each is typically use

In my experience, it seems to. My astigmatism (or other eye stuff) seems to move different colours different amounts, leading to wider RGB pixels and making things like Cleartype so much worse. So people were enjoying Cleartype and I was ha

It's not like the Cleartype tuner actually does what the pages claim - you can go through and use the magnifier to choose the grayscale-only outcomes and still see Windows doing RGB stripe cleartype throughout. People literally have to

The inhibition of movement via eddy currents works best while the needle is moving fast, so you can still end up with smaller oscillations for a while - the apparent jump-cut to a stationary needle could be hiding that. It's far easier

Your site still says "HOW TO ADD ALMOST EQUAL TO IN HTML? Use an HTML entity, a decimal code, or a hex code." That is incorrect. As you say, you should just write the character in your HTML and ensure it's served with the co
