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.

A* Tricks for Videogame Path Finding
Small NP-hard problems aren't actually that bad. You can usually formulate them as eg a integer programming problem or a SMT problem, and throw an off-the-shelf solver at them.
You only need to learn the solver once, and you can re-use it for all kinds of problems. (Assuming that your instances don't have to be solved with low latency. Eg only as part of your level generation process, or at most when loading a randomly generated level, but not every frame or so.)
https://developers.google.com/optimization has a decent collection of tools.

Ask HN: Comment here about whatever you're passionate about at the moment
Just saw that it looks like an upcoming release of OR-Tools might include reified tables: https://github.com/google/or-tools/commit/94f3d9b46870e7ea04...

[P] Advice needed for what tool/algorithm is appropriate
Google OR - Tried to represent a solution to be a 5 dimensional matrix with an hour granularity. Dimensions are stations, program, project manager, day and time. If matrix[station][program][project manager][day][time] = 1, then that set is assigned, otherwise not. The main issue encountered here is about time slots, as they are not necessarily on a per hour basis. We tried time slots to be in a 5-minute interval. However, constructing the constraints that would adhere to each programs duration was proven to be difficult.

Sudoku solver
If you are just interested in getting a solution or for having a reference solver: There is a sudoku example in the OR-Tools package that uses constraint programming.

Linear Programming
Not sql, but check out google’s OR-Tools. Hardly ever gets mentioned but looks very capable for some applications. https://developers.google.com/optimization

Would anyone know how to auto schedule tasks based on certain constraints?
Then there's also the Google's solution: https://developers.google.com/optimization/

Assignment to at most K groups from distance matrix?
start enumerating the properties you think the solution to your problem should have. once you have this, you should be able to reformulate those properties as constraints and then you can just plug this into a combinatorial solver such as https://developers.google.com/optimization

Unity's Licensing Changes: Discover Stride a Community-Driven Open-Source Engine
> Unfortunately, this is yet another open source game engine with too small a user base.
I wonder why some engines are seemingly destined for success and others... aren't.
Godot got really big, despite a somewhat similar feature set: https://godotengine.org/ (really nice 2D support, 3D rendering was worse until version 4, GDScript has both a nice iteration speed but also has gotten some criticism, while C# was a second class citizen in the earlier iterations)
Stride is really nice and seemed like it should have been the Unity replacement that people would look at, if it had gotten more attention and a community would have formed around it, like Godot's.
There's also NeoAxis which is way more Windows centric, but still seems to be getting updates and is comparatively easy to use, yet similarly never got popular: https://www.neoaxis.com/
Weirder yet, Java doesn't really have that many game engines out there, at least the likes of Unity/NeoAxis/Stride that have nice editors, despite the language being pretty nice. The closest I can think of is jMonkeyEngine which I donated some money in the past to, which is pretty usable but similarly niche: https://jmonkeyengine.org/
I occasionally watch videos on the Gamefromscratch YouTube channel (https://www.youtube.com/@gamefromscratch/videos) and it surprises me that there are so many engines out there, but very few actually are in the public eye. If you don't go out of your way to look for other options, you will most likely only have heard of Unity and Unreal (or maybe also Godot in recent years). I wonder why that is.

My recommendation on which language and libraries to use for the engine.
There more `bare-metal` engines like https://jmonkeyengine.org/ (well it is not C++, it is Java based)...

[Hobby] Need help implement Continuous Collision Detection in a classic top-down multiplayer space shooter
This project develops a cross-platform Subspace client and server written in Java. It was developed from scratch on the idea of extensibility and modularity. The server is based on modules/frameworks highly optimized for scaled, networked, grid-based, infinite world physics. The client is based on the JMonkeyEngine, a minimalistic modern developer friendly, open source, game engine

Godot 4.0 Stable
> Godot is one of those pinnacle FOSS projects that just totally impresses me, especially given the state its in now, with 4.0.
It is definitely one of the success stories, at least so far.
For example, there are projects like jMonkeyEngine (a game engine in Java, on top of LWJGL) that don't get as much attention and their movement forwards is way slower: https://jmonkeyengine.org/
There's also Stride 3D, which is a bit closer to Unity I'd say, which is still a really nice project, but is also limited in how much development can be done: https://www.stride3d.net/
Regardless, I wish all of those projects success and would still be glad if Godot could be one of the champions of open source game engines, perhaps as a viable and easy to use alternative to something like Unity for those who want that sort of thing, even in the professional development space eventually!
- Can I use any Java 3D or jMonkey with Codebase one?

I can't think about another video game using Java. I mean, there WILL be more but i haven't saw them.
It is, or at least was, efficient. Java has a great game engine called https://jmonkeyengine.org/ that at the time could compete with Unity, not sure the status now. And LWJGL, the lower layer for ooengl, was quite nice to use and it is efficient to go that low level if you plan to do a game that does not fit the stereotypes in such game engines, as you will find yourself fighting the engine more than the actual game.
