I can think of a number of cases where "dynamic" would be a bad thing, but not necessarily pejorative. The structure of a building had better not be dynamic (think "sudden energetic disassembly"), and when my (salaried, should be steady) paycheck becomes dynamic, I have to talk to HR. Can someone come up with a pejorative? [[Special:Contributions/162.158.78.212|162.158.78.212]] 11:16, 11 June 2020 (UTC)

As there exists such a thing as resilience by explicitness, when it comes to type system discussions in computer programming design the term 'dynamic' can be pretty condemning.

Can someone with knowledge of the reference system in a wiki make the reference appear above the discussion, maybe in a section named References?--Kynde (talk) 07:06, 11 June 2020 (UTC)

Well bugger me (METAPHOR! METAPHOR!) but my current Master thesis in Computer Science could use that term without much shoehorning. (tl;dr: Binary search trees that adapt, =dynamic, can serve a query series faster than static, and the gain depends on the structure of the query series, =entropy. I prefer the good old "instance optimality", though...) 162.158.159.122 08:58, 11 June 2020 (UTC)

This seems to tie in with the recent comic 2315: Eventual Consistency, which is also about entropy (in a thermodynamic(al) sense), but I guess that like the rest of the world I don't know what entropy really is, because if entropy is a measure of how "surprising" a variable is, why is everything being flat and spread out evenly called a state of maximum entropy? Everything being the same doesn't sound very surprising to me... --IByte (talk) 09:08, 11 June 2020 (UTC)

Because entropy is the inverse of how "surprising" or organized or full of information a system is. Bugstomper (talk) 09:27, 11 June 2020 (UTC)
It's not about "surprising" but about an even spread of probability, so for matter a complex molecule has less entropy than a smaller molecule because the atoms are held in place, and if the quarks in the atoms aren't even held together in subatomic particles then that is ultimate entropy. For information having more possible choices for the message or password spreads the probability of any one occurrence around more possibilities. If it is narrowly defined it has low entropy because the probability is concentrated in a few items.162.158.75.104 13:53, 11 June 2020 (UTC)

I can think of a number of cases where "dynamic" would be a bad thing, but not necessarily pejorative. The structure of a building had better not be dynamic (think "sudden energetic disassembly"), and when my (salaried, should be steady) paycheck becomes dynamic, I have to talk to HR.

As there exists such a thing as resilience by explicitness, when it comes to type system discussions in computer programming design the term 'dynamic' can be pretty condemning.
