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...) [[Special:Contributions/162.158.159.122|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 [[wikipedia:Entropy (information theory)|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... --[[User:IByte|IByte]] ([[User talk:IByte|talk]]) 09:08, 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.

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)

-:2050 retro slang: Dynamic, variant of Dienamic, portmanteau of Die and (Viet) Nam + adjectival suffix // Dienam (n): a long, brutal slog with an unsatisfying ending, possibly with unintended consequences arising some time after the conclusion (cv Agent Orange) "Just like the soldiers a century ago, they knew the project was a dienam -- resources would be wasted, careers ended, and goals unmet -- but they couldn't convince the executives to abandon the project." // Some[thing] that is a failure, many years in the making, from which no success can be extricated. "[The development team] was working on a dynamic project for the studio when [the studio] finally was forced to declare bankruptcy and shutter due to literally years of overcomitting and underdelivering." {{unsigned ip|162.158.75.104}}
-As there exists such a thing as resilience by explicitness, when it comes to type system discussions in computer programming language design the term 'dynamic' can be pretty condemning. {{unsigned ip|141.101.76.204}}
-(Looks like people aren't <nowiki>~~~~</nowiki>ing. My contribution starts here.) I can just see a reporter, at the scene of some breaking news, saying "It's very much a dynamic situation here", while dodging various rioter/police missiles, hurricane debris, moving away from a wildfire front or in the middle of a rescue situation in post-earthquake aftermath yet still amidst aftershocks.

-The 'Use “-ic” with nouns ending in “-ics” (usually)' section of that Free Dictionary article is relevant here, since dynamics is a thing. [[Special:Contributions/172.69.62.148|172.69.62.148]] 15:28, 12 June 2020 (UTC)
-Dynamic gravity, dynamic oxygen level, dynamic surgical compentency, dynamic astronomical unit ... none of these are desireable.
