人类也不是生下来就是大聪明，从婴儿到成人，吃喝拉撒 20 年，还得加上学校教育、社会教育，这些都消耗食物、水、电等等能源。如果算「全生命周期成本」，AI 其实挺高效的，训练一次，就能无限次回答问题，而人类每次思考还得再烧脑子——大脑耗能约 20 瓦。

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.。im钱包官方下载对此有专业解读
A few months ago, for instance, I watched my mother-in-law (who was born and raised in a village in northern Iran) teach Nava how to knock on wood for good luck. I hadn’t realized this was so widespread a practice until I checked Wikipedia and found that variants exist in Bulgaria (chukam na dǎrvo), Georgia (kheze daḳaḳuneba), Indonesia (amit-amit jabang bayi), Norway (bank i bordet ) and some two dozen other countries.
