I haven’t really run into any libraries wanting reflective access at all. All of our applications are on Java 21, except for one that relies on 8 because it uses jdk internals. What ones have you ran into? Jackson doesn’t even require you t

I thought this was the case but actually couldn’t find any documentation on it. The best I could find was that the vm is aware it is in a container and will correctly set the heap %’s based on the containers memory. It still looked like it

It’s valid criticism because you do need to think about it less in other runtimes, but it doesn’t always just work. There’s a reason why GOMEMLIMIT and other knobs for high allocation programs were introduced. IIRC .NET just sets it to 75%

In my experience I don’t see many people use final classes. Mostly just final fields.

Doens't jpackage still just make installers and not a single binary you can just run?

I believe they were calling the function tiny, which it is, it’s 27 lines.

GJS is why I went back to Windows. The interpreter would leak memory.

Its not a strange reply at all. _All_ of those languages are cheating. Those benchmarks are junk because they don't test implementations in the language.

Im sorry, but calling out to C libraries — regardless of the language — is cheating. Just because everyone in the competition is on steroids doesn’t mean you got there legitimately.

20% is frequently. And calling out to C is cheaty.

by vips7L 2y ago
Most the Debian benchmarks for C# are cheaty too. They frequently just call out to C libraries rather than use something implemented in the language.

I have friends who work in InsuranceTech and they use satellite images of houses when someone apply for home owners insurance. They've said it flags people with trampolines all the time.

In React I just use Formik and Yup to make forms painless. I've yet to discover a better way.

You can't compare 10 years ago Java to current Go. 10 years ago was Java 8, we are currently on Java 23. The performance difference is massive between these 2 runtimes especially between the available garbage collectors. Hazelcast has

Sometimes barrier to entry is good. For example, both npm and cargo struggle with package name squatting and malicious packages that are miss spellings of common packages.

Part of the reason why Haskell never took off. This stuff is incomprehensible.

I have a ton of opinions on exceptions too, mostly because I love them. FWIW you can override the stack trace collecting behaviour of Java exceptions. Not collecting the stack trace makes exceptions really fast and thats actually how Scala

Exceptions are great. Whats not great is not having them expressed in the type system via checking. I think Kotlin's greatest mistake is not improving upon checked exception handling. Though it looks like they're going to be movin

It feels so lambda and extension function heavy.

Sounds like the new “capabilities” stuff in Scala.

> having just switched over from CMS (!) This is really interesting. CMS was removed in Java 14 after being replaced by G1GC in Java 9. They were probably running an antiquated Java 8 or 11 runtime. So that means that in 2022 they were e

Kotlin is a Jetbrains product, not a Google one.

I agree its desperately needed. But we also desperately need investment in the language itself (not just the runtime).

Unfortunately I think we're currently in a state where all resources are going towards project Valhalla. Everything seems to be on hold until they get that out the door.

Reading more about how invokedynamic works, it appears that if your lambda doesn't capture it shouldn't allocate it more than one time.
