On my very first job at the turn of the century, I remember I was by a client seating in front of a server, looking at a black screen waiting for something to happen, highly doubting the claim of the client.
"It only works when you guys are here". Yeah, right.
Already 3 coworkers had to deal with this but couldn't find anything, this was more than strange. So I asked them to yell as soon as something happen.
15 minutes later my wandering thoughts were interrupted by Pipes materializing itself into existence. Oh. And for that day I was the hero.
As many here I'm in love with Total Commander for a long time and it was my first purchase.
I find equally amazing that it's a one man shop. Christian Ghisler created, maintains and supports this application for 30 years (initial release: 29th Sep 1993).
I have boundless admiration for this kind of dedication.
I still like to have a unique id field per table. It helps logging and it doesn't care about multi fields "real" key.
However I keep an unique index on the string value and more importantly point integrity constraints to it, mainly for readability. It's way easier to read a table full of meaningful strings rather than full of numerical id or uuids.
Another reason I saw was that models were trained on 512x512 "portrait" images including very few hands. Added to the inherent complexity of hands, this throw off their generation.
