Jenz··on The road to OCaml 5.0
A lighthearted but very true remark: OCaml is a wonderful language.
Jenz··on Bespoke Synth 1.0 – open-source software modular synthesizer
Haha this is the most amazing feature matrix I've ever seen.

On a more serious note, modular music is an extremely interesting and growing area and just about every module is surprisingly expensive; I'm curious to how well this translates to virtual racks.

Jenz··on Bringing “The Elements of Typographic Style” to the Web
And if people’s expectations of what links look like (blue, underlined) are so distracting it massively impacts the readers ease to read the actual content?
Jenz··on Bringing “The Elements of Typographic Style” to the Web
> No, it's an en space, which is something quite different.

Yeah, haha, at that point I lost the last hope I had of the author having much expertise in what he was doing.

That said I very much respect the obviously well-intended attempt, and hope the author’ll try again.

Practical Typography by Matthew Butterick [1] is a very nice introduction to typography for laymen.

Jenz··on “Computer science is not about computers”
There are large and finite structures in mathematics that would be very odd to call computer science. Take group theory and, say, the monster group [1].

Jenz··on An Introduction to Crystal
This is true, Crystal does compile pretty slowly, but this is the cost of its great static type system. The balance between Crystals expressiveness and performance is truly wonderful and a joy to program with

Jenz··on Haskell is a Bad Programming Language (2020)
Haskell is fantastic for programming systems where types are not just a tool, but central to the goals of the program. E.g. a program for converting one type of markup files to another (from one type to another type), like pandoc [1], which indeed is written in Haskell.

Indeed, this is a silly matter. In both sides.

Jenz··on V (Vlang) 0.2
The controversy around V is not without reason.

For some context here’s the last of a series of posts examining some of Vs claims https://christine.website/blog/vlang-update-2020-06-17

Jenz··on The Lady, or the Tiger? (1882)
Although the author is unwilling to state his answer, it's rather heavily implied she pointed him to the tiger.

> How often, in her waking hours and in her dreams, had she started in wild horror, and covered her face with her hands as she thought of her lover opening the door on the other side of which waited the cruel fangs of the tiger!

contra

> But how much oftener had she seen him at the other door! How in her grievous reveries had she gnashed her teeth, and torn her hair, when she saw his start of rapturous delight as he opened the door of the lady! How her soul had burned in agony when she had seen him rush to meet that woman, with her flushing cheek and sparkling eye of triumph; [...].

It is also interesting to see the sprinkles of social Darwinism throughout out the story.

> Had it not been for the moiety of barbarism in her nature, it is probable that lady would not have been there; but her intense and fervid soul would not allow her to be absent on an occasion in which she was so terribly interested.

What? Oh, well, in that regard most elements in any category is mediocre. Doesn’t really mean much...

Jenz··on Controversial Programming Opinions (2012)

Well, then, make the identity `arr[idx] == * (arr + idx-1)`.

Jenz··on Alternative notation for exponents, logs and roots? (2011)
> You don't need the ones with a different base.

To add on that, we need only one logarithm in the sense that all other then follows. For any base b, we have

log(x; b) = log(x)/log(b)

Jenz··on The Generalized f-Mean
They claim the inverse function of f(a,b) = a + b, is f(a,b) = a - b. Surely this is wrong. By my limited understaning of the basic structures of functions; when f: R^2 -> R, then f inverse ought to be R -> R^2 right? And when f is just addition there can’t be an inverse solving for both a and b.

(If one of a and b were fixed, it’d be way easier, that is, if f(a) = a + b, then g(a) = a - b is an inverse of f)

Jenz··on GNU Guix 1.2.0
I gave NixOS a serious try... the reason I gave it up was that pretty much all build systems for my own projects were broken and it was a pain to "nixify" them.
