That's right. From the linked JEP, under "Scheduler": > Some blocking APIs temporarily pin the carrier thread, e.g.most file I/O operations. The implementations of these APIs will compensate for the pinning by tempora

Yes, Java is finally becoming a language I don't cry myself to sleep over. I've still got other languages I (vastly) prefer, but I don't feel like I'm fighting the system nearly as much anymore. (Though, tail-call optimi

I'd love to know who, of those pinned to an LTS release, has actually made use of a support contract with a company providing contracted support for an LTS release, whether it's Oracle or another company. I don't doubt they e

Yes, by my reading of the linked JEP, these virtual threads are executed by a pool of honest-to-goodness OS threads (so a virtual thread might pause on one thread and get resumed on another).

I'm salivating over the context switching wins, myself. I've got a simulation system that uses threads to pause and resume modeled tasks at the appropriate times relative to the simulation clock, and we're just passing a toke

That would be my guess as well, and I would (casually, sitting in my armchair) expect two previews for such a significant change to the JVM. I'm not expecting it to land fully until Java 20 at least -- but we should absolutely give the

Tildes are used for strikethrough in some markup dialects (including mark down ), so I think they meant to depict replacing "its" with "Java's". No clue on the apostrophe.

If the pre-zoomed image was already downscaled (e.g. to fit a small display), then up to a point, zooming should simply downscale less , i.e. remove fewer pixels. Beyond that point, yes, a zoom would have to perform some kind of interpolat

Concurrent constraint programming is especially interesting to me -- Saraswat's ideas about a general constraint store (versus the Herbrand domain Prolog is usually instantiated over) are genuinely fascinating to me. I see the relative

That's a reasonable criticism. It works better in Reader View (because you can scale the font down, at least in Firefox), but I have to rotate to landscape as well.

What's wrong with the formatting? Plain text has a lot going for it. (I remember when most/all GameFAQs guides were text files just like this -- not to mention the Super Metroid guide [0] that manually justified every paragraph v

I think the M1 CPU lowers some of the ARC retain/release to silicon -- it doesn't remove the problem, but it does seem to reduce the relative overhead significantly. https://news.ycombinator.com/item?id=25203924 &

Divisibility can be cast in terms of subsets of the prime factor multisets. That is, for every number, we can translate it to its multiset of prime factors, e.g. 36 would become {2->2, 3->2}; then divisibility becomes the subset relat

Friends have suggested much the same, yeah. It feels unlikely due to a few factors, but I'm very willing to chalk that up to naivete on my part. (If nothing else, it's a convenient fiction that allows one to move on.)

My (mostly layperson's) understanding is that our laws of physics demand that causality would be broken; it's not taken as an axiom. Because of how the three dimensions of space and one dimension of time are put together, you can

Ah, very nice on both counts. It looks like instantiating generics over primitive types won't happen until a yet later JEP, and preview features tend to have a cycle time of at least two releases anyway, so I won't expect too much

I'd definitely be curious about which signals you're drawing on. From what I've seen, the Valhalla OpenJDK wiki has gone without update for quite some time, and even that wiki refers to JEP 169 ("Value Objects") as

Java annotations aren't executable on their own, so they're trivially type safe. The systems that do things depending on those annotations are typically reflection-based, which does an end-run around the static type system and usu

I suspect it has something to do with classfile format backwards compatibility. From a pure syntax standpoint, I would agree with you, but there's probably some value to making a very clear separation for classfile loading.

For myself, I'd like to see use-site variance replaced with declaration-site variance. It's really painful sometimes to have type arguments within generics more than one level deep; you have to start adding `? extends` (usually; o

Not yet. You can track Project Valhalla [0], the incubator for value/inline types in OpenJDK. But I don't get the sense it's landing particularly soon. https://openjdk.java.net/projects/valhalla/
