Hey you. Do you like low level programming? would you like to contribute to a large and well established project? Because I'm always looking to help new contributors getting started on GDB! It uses C++, but you may also end up needing to remove abstraction layers, so there's tons of things not-C++ to think about, if you want to.
I know that contributing to the GNU Debugger may sound like it's something that would be incredibly hard, or that you need ungodly amounts of knowledge to improve, because that's literally how I felt before sending my first patch, but the truth is, the project was developed by people (humans and otherwise), so silly bugs will abound, and simple oversights will need correcting. There is stuff for every level of programmer to do, from "I've worked on the kernel for 20 years" to "this is my 1st year in college and I'm not scared of large projects"
And here's the kicker, I want more contributors to the GDB project. So, if you are interested in this at all, you can hit me up and I will do my best to help you get setup to contribute (from compiling locally, to setting up git-send-email, running tests) and then help you understand the bugs, the code, and how to make a good commit message (to GDB's standards anyway). I've literally done code-walks with other mentees in the past, I eager to share as much of my experience as you would like to have! and I do my best to be ADHD/autistic friendly, since I'm AuDHD myself and would have really loved a mentor that did that for me in the past...
So... yeah, don't be afraid to reach out!
