New analysis of Apollo Moon samples finally settles debate: « For decades, scientists have argued whether the Moon had a strong or weak magnetic field during its early history (3.5 - 4 billion years ago). Now a new analysis shows that both sides of the debate are effectively correct. »

为官一任,造福一方。此后,在福建强调“牢记政府前面的‘人民’二字”;在浙江写下《心无百姓莫为“官”》;在上海走访各区县,党建与民生始终是念兹在兹的两件大事。习近平同志说,老百姓生活的品质怎么样,以民为本的宗旨落实得如何,“我到上海以后,比较关心这个事情”。

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.。业内人士推荐51吃瓜作为进阶阅读
