<p>
I use C#'s <code>IEnumerable</code> extensions quite a lot, and the javascript version, <code>linq.js</code>, is very large.<br/>
My version is 1.25kb.

<p>
Alpine Linux is a minimal linux distro, great for docker.<br/>
I wanted to query its package manager, APK, from Node.

<p>
NPM's package.json <code>scripts</code> is quite convenient for running things.<br/>
Yet, <code>npm run X</code> and <code>yarn X</code> are fairly slow - 150ms+.<br/>
nr is a simple bash script using jq to run scripts. 30ms. Much faster.

<h3><a href="https://github.com/adamburgess/celeste-high-frame-rate#readme">https://github.com/adamburgess/&ZeroWidthSpace;celeste-high-frame-rate</a></h3>
<p>
Celeste is a fun platformer, with a banger soundtrack.<br/>
The developers lock the ingame framerate to 60 fps, which is in my opinion <b>painful</b>.<br/>
This small patch overrides that limitation, and the game easily hits 240fps.

Escape from Tarkov has a day/night cycle.<br/>
This site shows you the time, and how long it will be to a future time. Deployed on netlify.

A helper for <code>ffmpeg</code>'s <code>crop</code> filter.<br/>
Drag and drop an image and select it to get a crop filter in the correct format.

<p>
bundlephobia.com uses webpack. I've found it gives slightly inaccurate results because of this.<br/>
I also wanted to get the brotlified sizes for my packages.<br/>
This builds the package with rollup. Deployed on fly.io.<br/>
No UI as of yet, but it also generates <a href="https://bundlephobia.fly.adam.id.au/size/@adamburgess/linq?shield&brotli">shields</a> see the readme of my linq package above for examples.

<h3><a href="https://github.com/adamburgess/image-builder">https://github.com/adamburgess/&ZeroWidthSpace;image-builder</a></h3>
<p>
I build a lot (all) of my projects with Docker, so I've made my own base images. <br/>
Using Github Actions and a generated Makefile, they automatically update whenever a dependency changes whether it be the docker image, an alpine package, a github/lab repo, or an npm package.
