'ZDNET Recommends': What exactly does it mean?
。新收录的资料对此有专业解读
当大模型迈向由数十亿用户主导的实时推理阶段,科技局头们都逐渐意识到一个关键现实:
You might have noticed the row estimates (599 and 28,458) are lower than you'd expect for a 50-million-row table. The planner checks the actual physical file size. Our table is only 74 pages on disk, not the 123,513 we injected. Hence the planner scales reltuples down proportionally. The absolute numbers shrink, but the ratios between them stay correct, and it's the ratios that determine plan shape. When you use pg_dump --statistics-only in practice, you're typically restoring into a database with comparable data volume, so the estimates align naturally.
I appreciate the Voyager for its elegance, but I don’t travel with it, so the super thin keycaps were not a selling point for me. I got resin-printed key covers to replace the top row of unused switch slots and a set of KLP Lamé keycaps from 3dkeycap to give a sculpted profile to the remaining keys. They are blanks in a solid grey color that lets the keyboard LEDs shine through. I don’t like animated keyboard LEDs, but I have customized solid LED colors to make each layer visually distinct and to help me out with some infrequently used keys. My Voyager has clicky Kailh Choc White keyswitches.
