Programming memes from a multi-decade ✝️ dev on a relaxing side quest before the final boss.

Cache locality and pointers were significantly less of a performance concern in olden times. Of course everything else sucked so there isn’t anything to reminisce over.

The lion only declares unsigned machine word variables because the lion knows everything else is an illusion.
“I don’t want to even look at this diff” Looks at the diff
Me: “How in the world could this code ever be needed??” Also me: reads my 10 year old comment specifically outlining the scenario where this code is needed Me: “Ah”
800x600 was such an intermediate resolution, it is hard to accept that it was a thing people used.

Maybe I could have used AI to refactor that but it’s irrelevant because 90% of the total time was spent looking at the diffs to make sure everything was right.
SpaceX knows they are not recovering Starship so they are intentionally testing to destruction. The entire point is to see if the intentional removal of heat tiles in critical areas produces catastrophic failure. It didn’t and that means losing tiles doesn’t mean loss of crew.

Today’s scrum status is sponsored by aspirational hopes and dreams

My goal at work today is to remove one variable. This is what peak performance looks like.
I’m not a fan of boasting but if you are in to it you should at least have done something to boast about.
There’s only one, it is old, even worse future Intel CPUs add a third kind of core so performance can be even less deterministic.
