I have been maintaining hub , the command-line git extension, for 10 years. After 2,100 issues and pull requests closed, 18k+ stars on GitHub, and countless hours invested in it, I thought it might be fitting to reflect on its unlikely past, share a bit about my process working on it, and address the future of GitHub on the command line.

Travis CI added a feature to cache dependencies between builds for their paying customers. In projects where resolving and fetching dependencies is a slow operation–e.g. in any Ruby project–this can shave a significant amount off total build time , resulting in faster feedback from CI for the developer. This post explores a DIY method of providing such a cache to open source projects as well .…
