My basic point is that currently, configuration management code manifests as a giant, unverifiable pile of mud. The languages we use lack types and are weak at making non-runtime assertions. With the modicum of sanity that a proper module system and types can bring to the table, we would be considerably better off.

GitHub RCE by Environment variable injection Bug Bounty writeup

Disclaimer: I'll keep this really short but  I hope you'll get the key points.

GitHub blogged a while ago about some internal tool called gerve:
https://github.com/blog/530-how-we-made-github-fast

Upon git+sshing to github.com gerve basically looks up your permission
on the repo you want to interact with. Then it bounces you further in
another forced SSH session to the back end where the repo actually is.

Ruby 2.1.0 in Production: known bugs and patches

Last week, we upgraded the github.com rails app to ruby 2.1.0 in production.
While testing the new build for rollout, we ran into a number of bugs. Most of
these have been fixed on trunk already, but I've documented them below to help
anyone else who might be testing ruby 2.1 in production.

@naruse I think we should backport these patches to the ruby_2_1 branch and
release 2.1.1 sooner rather than later, as some of the bugs are quite critical.
I'm happy to offer any assistance I can to expedite this process.
