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.

How moving from Pandas to Polars made me write better code without writing better code
In comes Polars: a brand new dataframe library, or how the author Ritchie Vink describes it... a query engine with a dataframe frontend. Polars is built on top of the Arrow memory format and is written in Rust, which is a modern performant and memory-safe systems programming language similar to C/C++.

From slow to SIMD: A Go optimization story
I learned yesterday about GoLang's assembler https://go.dev/doc/asm - after browsing how arrow is implemented for different languages (my experience is mainly C/C++) - https://github.com/apache/arrow/tree/main/go/arrow/math - there are bunch of .S ("asm" files) and I'm still not able to comprehend how these work exactly (I guess it'll take more reading) - it seems very peculiar.
The last time I've used inlined assembly was back in Turbo/Borland Pascal, then bit in Visual Studio (32-bit), until they got disabled. Then did very little gcc with their more strict specification (while the former you had to know how the ABI worked, the latter too - but it was specced out).
Anyway - I wasn't expecting to find this in "Go" :) But I guess you can always start with .go code then produce assembly (-S) then optimize it, or find/hire someone to do it.

Time Series Analysis with Polars
One is related to the heritage of being built around the NumPy library, which is great for processing numerical data, but becomes an issue as soon as the data is anything else. Pandas 2.0 has started to bring in Arrow, but it's not yet the standard (you have to opt-in and according to the developers it's going to stay that way for the foreseeable future). Also, pandas's Arrow-based features are not yet entirely on par with its NumPy-based features. Polars was built around Arrow from the get go. This makes it very powerful when it comes to exchanging data with other languages and reducing the number of in-memory copying operations, thus leading to better performance.

TXR Lisp
IMO a good first step would be to use the txr FFI to write a library for Apache arrow: https://arrow.apache.org/

3D desktop Game Engine scriptable in Python
https://www.reddit.com/r/O3DE/comments/rdvxhx/why_python/ :
> Python is used for scripting the editor only, not in-game behaviors.
> For implementing entity behaviors the only out of box ways are C++, ScriptCanvas (visual scripting) or Lua. Python is currently not available for implementing game logic.
C++, Lua, and Python all implement CFFI (C Foreign Function Interface) for remote function and method calls.
"Using CFFI for embedding" https://cffi.readthedocs.io/en/latest/embedding.html :
> You can use CFFI to generate C code which exports the API of your choice to any C application that wants to link with this C code. This API, which you define yourself, ends up as the API of a .so/.dll/.dylib library—or you can statically link it within a larger application.
Apache Arrow already supports C, C++, Python, Rust, Go and has C GLib support Lua:

Interacting with Amazon S3 using AWS Data Wrangler (awswrangler) SDK for Pandas: A Comprehensive Guide
AWS Data Wrangler is a Python library that simplifies the process of interacting with various AWS services, built on top of some useful data tools and open-source projects such as Pandas, Apache Arrow and Boto3. It offers streamlined functions to connect to, retrieve, transform, and load data from AWS services, with a strong focus on Amazon S3.

Wheel fails for pyarrow installation
I am aware of the fact that there are other posts about this issue but none of the ideas to solve it worked for me or sometimes none were found. The issue was discussed in the wheel git hub last December and seems to be solved but then it seems like I'm installing the wrong version? I simply used pip3 install pyarrow, is that wrong?

3D desktop Game Engine scriptable in Python
For open source 3d engines that use Python check out Panda3D or Ursina. They're both a blast to use and let you write your codd how you want.

Alternative Game Engines for Marooned Unity Developers
Panda3D: Let's you make games with c++ and python. I don't think there is an "editor" or anything like that with this engine, but it does look like there have been some decent games made with it. Could be good for smaller games. Modified BSD License.

Game Development Post-Unity
I know a lot of people recommend Godot because it's super good but if you want a more code oriented and batteries included engine I recommend Panda3D [0] it's open source, super mature (it's actually one of the oldest continously developed game engines), and can be used form Python and C++. Not sure why it's not more popular it's flexiable and super fun to use.

What are some of the most impressive uses of photogrammetry in games that you've seen?
Some of the game engines we have now have photogrammetry technology built-in, meaning that developers can easily integrate it into their games. This allows for even more detailed and realistic environments to be created in 3D games. The most prominent being Unreal, Unity, and Lumberyard -- including new and beginner-friendly ones like Panda3D and Yahaha. All of these game engines have photogrammetry at their core to help developers create realistic 3D models and textures quickly and efficiently.

Here are some tips on mentoring junior developers in a collaborative team?
Make sure to provide your junior developers or any new members with the resources and tools they need to succeed. This could include coding books (The Self-Taught Programmer was my favorite before), online tutorials, or access to development tools and software. There are game engines available that can be a training ground for new devs, some of the game engines I’ve tried are Panda3D, GameMaker and Godot. I’ve also tried newer engines like Yahaha, but this one is pretty easy compared to other engines so there’s really not much of a challenge. The point is, no matter what resources and tools you provide, make sure they are tailored to the skill level of your junior developers.

The Icculus Microgrant is giving out 250 dollar grants to open source projects, please brag about your project(s) in this thread so I can see them!
It's not my project, but https://www.panda3d.org/ is to my knowledge the next best step after Unity and Unreal game engines. Unlike those, panda is open source and available for C++ and Python.
