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.

關恆的代理律師陳闖創告訴BBC，關恆的案件有其獨特性，主要是在於他在中國的時候沒有受到直接的政治迫害，但關鍵是他的情況在離開中國之後發生變化。陳闖創指，在特朗普重新上台之後，儘管美國庇護相關的法律沒有改變，但目前是加強收緊、更嚴格地解讀各種庇護申請的案件，「確實在這個範圍內更嚴格了。」
Temperatures fell to freezing, food and water were rationed. It was days before they limped back to the fringes of Earth's atmosphere. They climbed back aboard the Odyssey and prayed the heat shield had not been damaged.
