Welcome! This is the first post on gradient ascent and also one that tests all +of the features.

I’ll be writing about computers, code, math, video games, and whatever else +here.

A monad is just a monoid in the category of endofunctors, what’s the problem?

haskell?

This entire blog is generated with hakyll. It’s +a library for generating static sites for Haskell, a purely functional +programming language. It’s a library because it doesn’t come with as many +batteries included as tools like Hugo or Astro. You set up most of the site +yourself by calling the library from Haskell.

Here’s a brief excerpt:

main :: IO ()
+main = hakyllWith config $ do
+    forM_
+        [ "CNAME"
+        , "favicon.ico"
+        , "robots.txt"
+        , "_config.yml"
+        , "images/*"
+        , "out/*"
+        , "fonts/*"
+        ]
+        $ \f -> match f $ do
+            route idRoute
+            compile copyFileCompiler

The code highlighting is also generated by hakyll.

why?

Haskell is a purely functional language with no mutable state. Its syntax +actually makes it pretty elegant for declaring routes and “rendering” pipelines.

I originally wanted to build this entire blog myself. I had a working version +with the Svelte framework, complete with GFM rendering, table of contents, KaTeX +math, code highlighting, static generation, and other goodies. However, it +seemed like a little too much work to maintain. I switched to hakyll because

Haskell is cool.
It comes with enough features that I don’t feel like I have to build +everything from scratch.
It comes with Pandoc, a Haskell library for converting between markdown +formats. It’s probably more powerful than anything you could do in nodejs. +It renders all of the markdown to HTML as well as the math. +
1. It supports KaTeX as well as MathML. I’m a little disappointed with the +KaTeX though. It doesn’t directly render it, but simply injects the KaTeX +files and renders it client-side.

speaking of math

We can have math inline, like so: + $\int_\infty^\infty \, e^{-x^2}\,dx = \sqrt{\pi}$ . This site ships semantic +MathML math with its HTML, and the MathJax script to the client.

It’d be nice if MathML could just be used and supported across all browsers, but +unfortunately we still aren’t quite there yet. Firefox is the only one where +everything looks 80% of the way to LaTeX. On Safari and Chrome, even simple +equations like $\sqrt{\pi}$ render improperly.

Pros of MathML:

A little more accessible
Can be rendered without additional stylesheets. I just installed the Latin +Modern font, but this isn’t even really necessary
Built-in to most browsers (#UseThePlatform)

Cons:

Isn’t fully standardized. Might look different on different browsers
Rendering quality isn’t as good as KaTeX

This site has MathJax render all of the math so it looks nice and standardized +across browsers, but the math still displays regardless (like say if MathJax +couldn’t load due to slow network) because of MathML. Best of both worlds.

Let’s try it now. Here’s a simple theorem:

$+a^n + b^n \ne c^n \, \forall\,\left\{ a,\,b,\,c \right\} \in \mathbb{Z} \land n \ge 3 +$

The proof is trivial and will be left as an exercise to the reader.

seems a little overengineered

Probably is. Not as much as the old one, though.
