This was an interesting statement coming from Julia (whose reputation amongst developers is impeccable, if you ask me):
Another benefit of doing this was that now I have actual code that I’ve written out in the open on GitHub! I don’t really believe in “github is your resume” (lots of great programmers don’t do any open source work! that’s fine!) but it does feel good to have.
One huge benefit to employees who work for open source-oriented companies is that they get to build an open source portfolio on the job. That levels the playing field for folks who don’t have the luxury of disposable free time outside business hours.
