Everything Is Logarithms

The dimension of a vector space is the cardinality of its basis. [log f = by x] gives something that at least resembles the function's representation as scalar relation, but i suspect these are merely confusions of concepts. when you take general covariance to its extreme you end up asking that all of your mathematics be formulated in an explicit co-variant way, and that

Prefer duplication over the wrong abstraction (2016)

https://images.squarespace-cdn.com/content/v1/537c0374e4b0f52ed92942e6/1406255585576-8V9OA9Q3VR7LM1P1NCAE/logo-color.png?format=1500w
The "wrong abstraction" problem occurs when code is modified to accommodate new requirements, leading to conditionals and duplicated logic, making it hard to understand and maintain. The solution is to "go back" and remove the abstraction, inlining code to make it easier to understand and add new features, rather than trying to preserve the existing code.
