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.

Show HN: Integer Map Data Structure
Neat, thank you! I'd love to see how it compares to the libgdx IntMap[0].

OSS Game Engines are increasing their stars on GitHub due to Unity's missteps
For anyone interested, LibGDX[1] is a very nice open-source game engine for Java. It is cross-platform (mobile, PC/mac, web). Very popular and well maintained, too.

Transfer from Processing to LibGDX. I need your advises.
Source is also available on github https://github.com/libgdx/libgdx to directly check the implementation of a specific classes.

(Java) Is there any way to convert InputStream to temp File without OutputStream?
And let me explain, for example jorbis this library has a lot of nested loops in it, i understand why this library using this, but this is really bad. Because when I am trying to use library with this code, this taking so much time to convert ogg to pcm, and yes I know that converting ogg to pcm is a hard process, but I need to optimize my program, make it more better. The main thing is EVERY decoding ogg file library using the same piece of code! And I am not joking for example libgdx.

(Java) How to .ogg file convert to pcm?
What the pcm file contains? And what is the structure? What data I should use for converting .ogg file into pcm? Is there any information about pcm files? Is there any repositories in github that converts .ogg files into pcm? (I am already know there is JVorbis, libgdx and jorbis but thats not what i want)

This Watcher seed is divine, its a sin to not try it out if you can. (on pc)
There's a code snippet showing the seed generation and how it feeds into each RNG pattern but it also mentions the use of a "xorshift128+ algorithm" here: https://github.com/libgdx/libgdx/blob/master/gdx/src/com/badlogic/gdx/math/RandomXS128.java

Contacting an author of libGDX or someone that can answer a legal question?
I can't guarantee you'll get a reply, but Mario and Nate's email addresses are in the AUTHORS file.

Instancing/Instanced Rendering in LibGDX (3D)
I found an example for rendering a [Mesh] object using instancing in LibGDX's tests (link), but I'm not sure how to apply that for rendering actual models.

How to convert gradle project to ant project?
assuming you use that (https://github.com/libgdx/libgdx/blob/master/build.gradle) as your starting point. You first have to ask what it is that your build should cover. Do you need all the spotless checks and release flags and so on or do you just need to package everything up so that it could run.

Arena-Based Parsers
The description indicates it is not production ready, and is archived at the same time.
If you pull all stops in each respective language, C# will always end up winning at parsing text as it offers C structs, pointers, zero-cost interop, Rust-style struct generics, cross-platform SIMD API and simply has better compiler. You can win back some performance in Go by writing hot parts in Go's ASM dialect at much greater effort for a specific platform.
For example, Go has to resort to this https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f... in order to efficiently scan memory, while in C# you write the following once and it compiles to all supported ISAs with their respective SIMD instructions for a given vector width: https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (there is a lot of code because C# covers much wider range of scenarios and does not accept sacrificing performance in odd lengths and edge cases, which Go does).
Another example is computing CRC32: you have to write ASM for Go https://github.com/golang/go/blob/4ed358b57efdad9ed710be7f4f..., in C# you simply write standard vectorized routine once https://github.com/dotnet/runtime/blob/56e67a7aacb8a644cc6b8... (its codegen is competitive with hand-intrinsified C++ code).
There is a lot more of this. Performance and low-level primitives to achieve it have been an area of focus of .NET for a long time, so it is disheartening to see one tenth of effort in Go to receive so much spotlight.

Airline keeps mistaking 101-year-old woman for baby
It's an interesting "time is a circle" problem given that a century only has 100 years and then we loop around again. 2-digit years is convenient for people in many situations but they are very lossy, and horrible for machines.
It reminds me of this breaking change to .Net from last year.[1][2] Maybe AA just needs to update .Net which would pad them out until the 2050's when someone born in the 1950s would be having...exactly the same problem in the article. (It is configurable now so you could just keep pushing it each decade, until it wraps again).
Or they could use 4-digit years.

The Performance Impact of C++'s `final` Keyword
Yes, that is true. I'm not sure about JVM implementation details but the reason the comment says "virtual and interface" calls is to outline the difference. Virtual calls in .NET are sufficiently close[0] to virtual calls in C++. Interface calls, however, are coded differently[1].
Also you are correct - virtual calls are not terribly expensive, but they encroach on ever limited* CPU resources like indirect jump and load predictors and, as noted in parent comments, block inlining, which is highly undesirable for small and frequently called methods, particularly when they are in a loop.
* through great effort of our industry to take back whatever performance wins each generation brings with even more abstractions that fail to improve our productivity

Java 23: The New Features Are Officially Announced
If you care about portable SIMD and performance, you may want to save yourself trouble and skip to C# instead, it also has an extensive guide to using it: https://github.com/dotnet/runtime/blob/69110bfdcf5590db1d32c...
CoreLib and many new libraries are using it heavily to match performance of manually intensified C++ code.

Why choose async/await over threads?
We might not be that far away already. There is this issue[1] on Github, where Microsoft and the community discuss some significant changes.
There is still a lot of questions unanswered, but initial tests look promising.
