Postgres has its own primitives for things that forges currently build custom infrastructure around. A trigger on the refs table firing NOTIFY means any connected client learns about a push the moment it happens, which is how forges normally end up building a custom webhook polling layer. Multi-tenant repo isolation becomes a database concern through row-level security on the objects and refs tables, and logical replication lets you selectively stream repositories across Postgres instances, a kind of partial mirroring that filesystem-based git can’t do. Commit graph traversal for ancestry queries and merge-base computation falls to recursive CTEs, and pg_trgm indexes on blob content give you substring search across all repositories without standing up a separate search index.
Nvidia’s participation in the round has been the subject of intense speculation, particularly as reports of a $100 billion investment in September gave way to reports of a smaller investment in the months that followed.，详情可参考91视频

Like the Evo, the Shot 3 Retro features an LCD screen — albeit a much smaller one — that lets you decide whether to print a shot. It also supports Bluetooth, and you can use the Kodak Photo Printer app to upload photos to social media or print decent, relatively crisp images from your phone. Unlike the Evo, however, the Shot 3 Retro retails for around $170 and includes a pack of film. It also uses cheaper film; you can often pick up a 60-sheet cartridge for under $20. The cheaper arguably encourages creative experimentation, even if the large 3 x 3-inch square prints feel lower in quality and more flimsy than those from both Fujifilm and Polaroid.
