This site also has courses on web dev. Plus extra courses such as a course on refactoring that I really liked.

3. Open Source Contribution

I wrote a book with a chapter on how to write docs for other people’s code https://howtoopensource.dev

I also wrote an open source tool for writing and testing tutorials https://github.com/zombocom/rundoc and another that will email you undocumented methods of open source code so you can practice writing documentation https://www.codetriage.com/.

CodeTriage helps you contribute to open source by “picking a handful of open issues and delivering them directly to your inbox”. (Source: CodeTriage)

Here are open source projects listed https://www.codetriage.com/ You can filter for "C".

The biggest untaped potential (IMHO) is not one company funding 1 full time maintainer, but EVERY company allowing and encouraging EVERY developer to help and work with open source. This was the basis of my web app https://www.codetriage.com/. I have a chapter on it in my book How to Open Source (https://howtoopensource.dev/), and I talked to Yehuda about it for about an hour after my last talk at Philly ETE.

You can also use websites like up-for-grabs, goodfirstissue, or CodeTriage to find projects with open issues. Find one that looks easy or interesting to you and comment on it, asking if you can take a shot at it.

I recommend these resources to help you contribute https://www.codetriage.com/ (free) and https://howtoopensource.dev/ (paid). DM if you can’t afford a copy.
