Independence (mathematical logic) by Ciro Santilli 35 Updated +Created
A theorem is said to be independent from a set of axioms if it cannot be proven neither true nor false from those axioms.
It or its negation could therefore be arbitrarily added to the set of axioms.

HyperCard by Ciro Santilli 35 Updated +Created
This was the pre-Internet precursor of wikis. This program was likely venerable, shame it predates Ciro Santilli's era.
But the thing was much more bloated it seems, and also included visual programming elements, and WYSISYG UI creation.

This is obviously the most efficient investment any non-English speaking country must do, because you need to know English to be able to learn from rich countries and innovate.

This webcomic is venerated by software engineers as of 2020.
Being able to quote the right one at the right time is considered a fundamental shibboleth of the profession.
And with reason.
Meta breaking glitch by Ciro Santilli 35 Updated +Created
A meta breaking glitch of a video game is a glitch that when discovered significantly breaks the meta.
In non-video game-game, it does sometimes happen that a meta is broken as well, but these events tend to be rarer and less dramatic than meta-breaking due to computer program glitches.
In PvP games, those glitches are generally forbidden by existing rules, and quickly patched after discovered.
In speedrunning however, they are either incorporated in the existing strategy, or may lead to the creation of a new run category for particularly significant glitches.

Manifold by Ciro Santilli 35 Updated +Created
We map each point and a small enough neighbourhood of it to , so we can talk about the manifold points in terms of coordinates.
Does not require any further structure besides a consistent topological map. Notably, does not require metric nor an addition operation to make a vector space.
Manifolds are cool. Especially differentiable manifolds which we can do calculus on.
A notable example of a Non-Euclidean geometry manifold is the space of generalized coordinates of a Lagrangian. For example, in a problem such as the double pendulum, some of those generalized coordinates could be angles, which wrap around and thus are not euclidean.
