OKRs Are Bullshit
It’s a new year, time for a new rant! And yes, before you ask, the post title is deliberately provocative. You might say this is my ploy to get more paid subscribers, because only paid subscribers can leave comments and I expect that the title alone will make many of you want to comment. 😝 […]
Two’s complement integers with only sign bit set should be a trap representation
@jrose (just for the frame: my background is computer science with a side of mathematics) the nuance here is really what operations are allowed/available. without any, each of the 2^32 bijections is an isomorphism so it’s not unique. with order (“
Vision 1993
