WHAT HAPPENS ON GITLAB WHEN YOU DO GIT PUSH?

Git stores project history locally as objects and references (like branches). When you use 'git push', and your git remote is with GitLab, it sends these updates to a remote GitLab server. How you connect (SSH or HTTP(S)) determines the authentication method: SSH uses GitLab Shell for key-based verification, while HTTP(S) relies on Workhorse and Rails for authentication. Once authenticated, Gitaly takes over, managing your Git repository and executing 'git-receive-pack' to handle the incoming changes. Gitaly is used by GitLab to read and write Git data.

RIP REDIS: HOW GARANTIA DATA PULLED OFF THE BIGGEST HEIST IN OPEN SOURCE HISTORY

The recent Redis license change by Redis Labs (aka Garantia Data) is a harmful move that disregards the contributions of the wider Redis community. Garantia Data didn't create Redis. Redis was initially an independent open-source project and Garantia Data only became involved years after its creation. Redis’ widespread adoption was thanks to the open-source community and Amazon’s ElastiCache, not due to the company itself.
