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.

Comma 3
Now in that video above you can see there is some "ping ponging" where the car seems to constantly move back and forth not sticking to the center of the lane well. This is mostly mitigated by a fork of the Openpilot software. Twilsonco's fork of sunnypilot uses a neural network to calculate the "torque feed forward" settings. It's quite ingenious. You can get very in depth with the C3.

Are you thinking about getting a Comma 3?

What's the most up to date status on Navigate on Openpilot?
Improvements to the lateral controls code so it uses the torque it has properly. This is in my Sunny-torque-plus branch that adds lateral jerk error response and uses a lower error response in curves to let feedforward do the work. Some other cars have also had big improvements from this. installer.comma.ai/twilsonco/sunny-torque-plus

Where do I find the differences in all the Branches within SunnyPilot, DragonPilot or OP.
what's the difference if I use https://github.com/twilsonco/openpilot/tree/sunny-test-c3 vs. https://github.com/sunnyhaibin/sunnypilot/tree/test-c3

What code/project you saw was both inspiring and maintainable?
yes I use it in a '18 Chevy Volt running my own fork with tons or original features. Here's some driving footage of my car.
- Sorry it's not a twin pic, but here's my Volt, inside and out
-
What should I look for when looking at a used Volt?
And '17 is the most supported by OpenPilot. It has auto resume for stop and go traffic. '18 doesn't auto resume. Other than that they're the same. My OpenPilot fork makes it magic.
-
Always love seeing the regular Volt family at my work everyday where we get to charge for free π€(and yes that's my customized plate on the right)
If you're in a Volt, check out my fork! https://github.com/twilsonco/openpilot

Programming from Top to Bottom - Parsing
You can never mistake type_declaration with an identifier, otherwise the program will not work. Aside from that constraint, you are free to name them whatever you like, there is no one standard, and each parser has it own naming conventions, unless you are planning to use something like LLVM. If you are interested, you can see examples of naming in different language parsers in the AST Explorer.

Look ma, I wrote a new JIT compiler for PostgreSQL
> There is one way to make the LLVM JIT compiler more usable, but I fear itβs going to take years to be implemented: being able to cache and reuse compiled queries.
Actually, it's implemented in LLVM for years :) https://github.com/llvm/llvm-project/commit/a98546ebcd2a692e...

C++ Safety, in Context
> It's true, this was a CVE in Rust and not a CVE in C++, but only because C++ doesn't regard the issue as a problem at all. The problem definitely exists in C++, but it's not acknowledged as a problem, let alone fixed.
Can you find a link that substantiates your claim? You're throwing out some heavy accusations here that don't seem to match reality at all.
Case in point, this was fixed in both major C++ libraries:
https://github.com/gcc-mirror/gcc/commit/ebf6175464768983a2d...
https://github.com/llvm/llvm-project/commit/4f67a909902d8ab9...
So what C++ community refused to regard this as an issue and refused to fix it? Where is your supporting evidence for your claims?

Rewrite the VP9 codec library in Rust
Through value tracking. It's actually LLVM that does this, GCC probably does it as well, so in theory explicit bounds checks in regular C code would also be removed by the compiler.
How it works exactly I don't know, and apparently it's so complex that it requires over 9000 lines of C++ to express:
