Git packfiles use delta compression, storing only the diff when a 10MB file changes by one line, while the objects table stores each version in full. A file modified 100 times takes about 1GB in Postgres versus maybe 50MB in a packfile. Postgres does TOAST and compress large values, but that’s compressing individual objects in isolation, not delta-compressing across versions the way packfiles do, so the storage overhead is real. A delta-compression layer that periodically repacks objects within Postgres, or offloads large blobs to S3 the way LFS does, is a natural next step. For most repositories it still won’t matter since the median repo is small and disk is cheap, and GitHub’s Spokes system made a similar trade-off years ago, storing three full uncompressed copies of every repository across data centres because redundancy and operational simplicity beat storage efficiency even at hundreds of exabytes.

The new Fire TV OS update makes navigating content even easier, adding tabs across the top for search, home, movies, TV shows, sports, news, and live content that pull recommendations from all of your subscriptions. Your apps now live on their own row, and you can pin up to 20 favorites instead of just six. You also get support for Alexa Plus, letting you search for specific types of content with your voice, jump to particular scenes, control compatible smart home devices, check sports scores, and more.
