Perhaps worth noting that the number of lines in a cache is often different than the number of rows, which can be relevant for some workloads. The size of an ordinary cache is rows × ways × size ( line ), where rows = 2 ↑ num-idx-bi

I believe Peano dot notation works the other way ’round; A . B : C :. D would be, as I understand it, equivalent to: ((A B) C) D The “general principle” is that a larger number of dots indicates a larger subformula. ¹ What i

I may be wrong, but I believe the name of the type family is simply Times New; the name of the italic face would then be Times New Italic rather than the contradictory Times New Roman Italic . It’s strange that the name of the roman fa

I’d argue there’s a very big difference between “x: y” and “x : y”. I can only see the former as assignment and the latter as the has-type relation. (I find it baffling in the extreme that in many mainstream languages the convention is to w

A small nit: the development of Unix began on the PDP-7 in assembly, not the PDP-11. (The B language was implemented for the PDP-7 before the PDP-11, which are rather different machines. It’s sometimes suggested that the increment and decre

I’ve noticed that, besides the magnetism and drive for sex (which would be sufficient for a species to propagate), many people also experience the biological imperative (wanting their genes replicated) as its own separate feeling. This make

At some point in my life I unconsciously decided that charisma (in this sense) was something I did not want to exercise, and was perhaps even wrong to exercise. In so many facets of our lives already, our wants are being manipulated for the

People may also be interested in the Tako shell, which is a fork of Xonsh that “sacrifice[s] some of the ‘fancy stuff’ so that basic shell operations work as expected, the codebase is small, and things are as performant as can be expected

You’d perhaps be better off using U+2002 EN SPACE (or the canonically equivalent U+2000 EN QUAD). From what I recall, the size of a typical interword space is ⅓ of an em, and traditionally a bit more than this is inserted between sentences

Belying the name somewhat, I believe U+3000 is specifically meant for use with Sinoform logographs, having the size of a (fullwidth character) cell, and so it makes little sense in other contexts.

The title of the submission should be changed to “Type in Wall·E”, “Typesetting in Wall·E”, or “Typography in Wall·E”; the word “typeset” is a verb or past participle, not a noun.

My line of thinking roughly was, "each type system corresponds to a particular logic system and vice versa; in a proof by induction, the different cases correspond to the type constructors, but what does the necessary axiom schema or s

How does infinite descent work using a proof assistant? It's been quite a while, so I may be remembering incorrectly, but this is my understanding: Coq uses an inductive type like "N = 0 : N | S : N → N", and a first-order th

It's a familiar concept to most people, though: most people understand that people have parents, grandparents, greatgrandparents, and so on. (Maybe a bad example; I feel like it shows that people are familiar with coinduction .)

Using indices is a (slight) improvement over pointers, since in Rust you will benefit from bounds checking (restricting you to the memory allocated for that tree). (If you use u32 for the indices, you also save some space.)
