You may know that GitHub encrypts your source code at rest, but you may not have known that we encrypt sensitive database columns as well. Read about our column encryption strategy and our decision to adopt the Rails column encryption standard.
New to Git v2.38, Scalar is a built-in repository manager for large repos. Here, we’ll tell the story of how Scalar went from a rough VFS for Git successor to a fully-integrated Git tool, with all of the engineering lessons learned in the process.
In September, we experienced one incident that resulted in degraded performance across GitHub services. We also experienced one incident resulting in significant impact to Codespaces. We are still investigating that incident and will include it in next month’s report. This report also sheds light into an incident that impacted Codespaces in August and an incident that impacted Actions in August.
Another new release of Git is here! Take a look at some of our highlights on what's new in Git 2.38.
The GitHub Actions team has done lots of work to improve the performance and resource consumption of Actions on GHES in the past year.
Developers all over the world are using GitHub Copilot to help speed up their development and increase developer productivity. With GitHub Copilot available to developers everywhere, we’ve found some fun and useful examples of how developers can use GitHub Copilot for things you may not be thinking about.
A tour of recent work to re-engineer Git’s garbage collection process to scale to our largest and most active repositories.
In August, we experienced one incident resulting in significant impact to Codespaces. We’re still investigating that incident and will include it in next month’s report. This report also sheds light into an incident that impacted Codespaces in July.
A software engineer’s personal journey to becoming an open source contributor.
This fifth and final part of our blog series exploring Git's internals shows several strategies for scaling your Git repositories that match related database sharding techniques.
We're examining Git’s internals to help make your engineering system more efficient. This post views Git as a distributed database and looks into its synchronization techniques, specifically ‘git fetch’ and ‘git push’.
Git’s file history queries use specialized algorithms that are tailored to common developer behavior. Level up your history spelunking skills by learning how different history modes behave and which ones to use when you need them.
This post explores Git commit history as a database where ‘git log’ is the query language. Learn about Git’s custom query index – the commit-graph file – and how to make sure it's enabled in your repositories.
This blog series will examine Git’s internals to help make your engineering system more efficient. Part I discusses how Git stores its data in packfiles using custom compression techniques.
We've open sourced Trilogy, the database adapter we use to connect Ruby on Rails to MySQL-compatible database servers.
