Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Java JEP 461: Stream Gatherers
Streams is too complex for what it does and it doesn’t even parallelize well. Here is something that does roughly the same thing but I think is way better

Java 21: The Nice, the Meh, and the Momentous
(1) It's a bit of a bad smell (which he points out) that records aren't being used much at all in the Java stdlib, I wrote something that built out stubs for the 17 and 18 stdlibs and that stood out like a sore thumb. I do like using records though.
(2) I've looked at other ways to extend the collections API and related things, see
https://github.com/paulhoule/pidove
and I think the sequenced collections could have been done better.
(3) Virtual Threads are kinda cool but overrated. Real Threads in Java are already one of the wonders of the web and perform really well for most applications. The cases where Virtual Threads are really a win will be unusual but probably important for somebody. It's a good thing it sticks to the threads API as well as it did because I know in the next five years I'm going to find some case where somebody used Virtual Threads because they thought it was cool and I'll have to switch to Real Threads but won't have a hard time doing so.

Ask HN: What problems do Generators solve in Java?
I think that guy just made up a generator class for fun. It’s not too different from the integrator except it doesn’t have a hasNext() method so it either returns results forever or it has to return a sentinel value like null or return an exception to end iteration.
Somebody could make the case that returning a sentinel value or an exception is a better API since there is no risk somebody else is going to call the next() method after you call hasNext() and next(). Writing a generator that wraps a generator is a little simpler than writing an interest or that wraps an iteration because you don’t have to write a hasNext() function, which can occasionally be awkward.
That generator library has a few functions, like map that work on generators, unfortunately the Java stdlib doesn’t come with anything like that. (There is the streams API but it is over-complicated.)
I’ll point out this library I wrote
https://github.com/paulhoule/pidove
which does a lot of what the Steams library does but it works on iterators without creating streams. If you like those generator examples you might like pidove.
As for Python it is kinda accidental that generators would up related to coroutines, that is, generators were an easy way to implement coroutines, later async/await and stuff like that got added.

Overinspired?
I find this alien to my point of view. On the other hand, my side projects aren't driven by FOMO but are more like the "special interests" of autistic people.
Most of the time I have three side projects going on, maybe two of which are really getting the attention they deserve and one that is languishing. (See my profile to see about my current three.) Occasionally I get inspired to spend 1-4 weekends on some sudden inspiration, of which
https://github.com/paulhoule/pidove
came to completion but
https://github.com/paulhoule/ferocity
probably won't. The project I'm working the hardest on now is something that I was baffled that it didn't exist 18 years ago but felt compelled to do something out because of the Twitterinsanity last December and it turned out the technological conditions right now make it the perfect time to work on.

JDK 20 and JDK 21: What We Know So Far
When I saw sequenced collections earlier I didn’t like the design but I completely approve of the latest revision. One nice thing about the process they use to develop Java is that they really do work and rework new features to make them great.
I just wish that instead of Streams they’d made something more like

I love building a startup in Rust. I wouldn't pick it again
... or you can just use a sane FP library like
https://github.com/paulhoule/pidove
Some people don't like the Lispy signatures so I did start coding up a version with with a fluent interface but didn't quite finish.

“I've never heard anyone say that they loved Java” (2001)
Inner classes are pretty useful.
This library contains a huge number of Iterables, each of which has at least one Iterator implementation.
https://github.com/paulhoule/pidove
It is convenient to let the Iterator be immutable and the Iterator be an inner class that gets its configuration information out of the Iterable.
(That said, if people really thought seriously about Iterator being a Supplier people might think more rationally about error handling. Also in a slightly parallel universe the Iterator would only have one method since remove() hardly ever gets used and having both hasNext() and next() methods is asking for bugs.)

Ask HN: Working Offline for 8 Hours?
If you were programming in Python or many other languages you could download documentation locally.
In both Python and Java doing a mini-project I frequently challenge myself to only use the standard library. It's good for practicing HackerRank-rank style programming (the fun of single-file Java)
When I am waiting for builds I sometimes hack on this
https://github.com/paulhoule/pidove
because I don't really like the Streams API and want to perfect my mastery of generics and internal DSLs.
Now that I think of it, standard-library only for node seems like a good challenge for me because I code a lot of front-end Javascript but just barely know the node API.

Rust to .NET compiler – Progress update
> There are online Rust compilers and interpreters already if you just want to rapid prototype and develop ideas in Rust
You are responding to one of the key developers of Rust early on[1], who's been working with the language for 14 years at that point.
[1] https://github.com/rust-lang/rust/graphs/contributors?from=2... and he's still #16 in commits overall today, despite almost no activity on the rust compiler since 2014.

Create a Custom GitHub Action in Rust
If you haven't dipped your touch-typing fingers into Rust yet, you really owe it to yourself. Rust is a modern programming language with features that make it suitable not only for systems programming -- its original purpose, but just about any other environment, too; there are frameworks that let your build web services, web applications including user interfaces, software for embedded devices, machine learning solutions, and of course, command-line tools. Since a custom GitHub Action is essentially a command-line tool that interacts with the system through files and environment variables, Rust is perfectly suited for that as well.

Why Does Windows Use Backslash as Path Separator?
Here's an example of someone citing a disagreement between CRT and shell32:
https://github.com/rust-lang/rust/issues/44650
This in addition to the Rust CVE mentioned elsewhere in the thread which was rooted in this issue:
https://blog.rust-lang.org/2024/04/09/cve-2024-24576.html
Here are some quick programs to test contrasting approaches. I don't have examples of inputs where they parse differently on hand right now, but I know they exist. This was also a problem that was frequently discussed internally when I worked at MSFT.

I hate Rust (programming language)
> instead of choosing a certain numbered version of the random library (if I remember correctly) I let cargo download the latest version which had a completely different API.
Yeah, they didn't follow the instructions and got burned. I still think that multiple things went wrong simultaneously for that experience. I wonder if more prevalent uses of `#[doc(alias = "name")]` being leveraged by https://github.com/rust-lang/rust/pull/120730 (which now that I check only accounts for methods and not functions, I should get on that!) so that when changing APIs around people at least get a slightly better experience.

Show HN: Fancy-ANSI – Small JavaScript library for converting ANSI to HTML
Recently did something similar in Rust but for generating SVGs. We've adopted it for snapshot testing of cargo and rustc's output. Don't have a good PR handy for showing Github's rendering of changes in the SVG (text, side-by-side, swiping) but https://github.com/rust-lang/rust/pull/121877/files has newly added SVGs.
To see what is supported, see the screenshot in the docs: https://docs.rs/anstyle-svg/latest/anstyle_svg/
