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.
折腾了这么多年数码设备，发现玩 Windows Phone 的学习成本是最高的，高于越狱时代的 iPhone，以及 Root 时代的 Android 设备。整个折腾过程需要各种工具、补丁和备份包，很多还得从存档网站、论坛附件或网盘里一点点捞出来，像是在打捞数字化化石。我尝试从 lumiafirmware 下载固件时，就被就被泼了一盆冷水，但好在等待了多个小时后顺利拿到了文件。
