You can find a lot of references to code in github as you browse through meta.discourse.org, but many of the links no longer work…
I think one solution would be to require that a github permalink is posted (or at least warn the poster when their github link is not a permalink).
I’ve come across dozens of them today. For example, see “How Discourse Stays Online - (Message Bus, Faye, Long Polling)”
You just hit
y to get a Permalink on Github.
So many broken links makes meta more difficult to use. Considering these links are typically posted by the Discourse founders, all the more likely to be followed into the future…
There are probably some exceptions that you’re 99% sure will stay around, such as README.md, but search for “https://github.com/discourse/discourse/blob/master/” and see how many of these are no longer valid.
