Datasette Lite

Full featured, extensible enumerations for javascript.
It seems like my pandemic super-power is starting a project, getting side-tracked by some aspect of that project, turning that into its own project and then forgetting about the thing I was originally working on. In that spirit, I give you enumerated types (not just constants!) for javascript. [more inside]
Needledrop
Needledrop is a skeuomorphic vinyl turntable interface for listening to music on YouTube. Use it with your favorite albums and share with friends. Try it out for good vibes.
blob-opera-midi
I became somewhat obsessed with the Google Blob Opera (FPP) and, more specifically, making it sing arbitrary songs (MIDI control is supported but very limited, or at least difficult to program manually). What started out as quick and dirty hack to convert 4-part MIDI arrangements to Blob Opera format JSON ended up as a slightly less quick and dirty standalone npm module. [more inside]
Codepip: coding games for learning web dev
A few years back, I released two CSS coding games as weekend open source projects: Flexbox Froggy and Grid Garden. Based on the positive reception they got, I was motivated to launch Codepip and expand into more games. Since launch I've added six games for learning different aspects of HTML, CSS, and JavaScript, with more in the works. Last week came Sourcery, which introduces the HTML workflow tool Emmet.

Numble Jumber - Simple Browser Puzzle Game
The title basically says it all. I made a simple browser puzzle game. You try to move the five blocks from one side of the screen to the other and place them in order. DIFFICULTY: You can't move the blocks individually. It works best on a computer using the arrow keys, but can also use swipe on mobile. If you are looking to kill a few minutes at work, give it a try.

FatFinger is a library that allows you to run JavaScript full of typos. It will look at your code, attempt to guess at your intent, and do its best to make the code runnable.

Mk Mrc Grt Gn! A Disemvoweling Twitter Bot
Inspired by a tweet from (metafilter's own) Maciej CegΕowski, I made a dumb Twitter bot using Glitch one night that disemvowels 45's mouthspew on Twitter as if he were a dumb troll trying his best to annoy the mods. The resulting tweets are collected at @Dsmvwld_PTS. [more inside]

Structured text editor component for the web
In a deplorable lapse of judgement, I decided that I would be the person to fix the sorry state of online content writing, where sites currently either use crude HTML or Markdown input fields, or infuriating WYSIWYG components. Seven months later, there is ProseMirror, an alpha-stage piece of software that might just grow into the editor I want the web to use. It even does collaborative editing because some problems are just hard to resist. [more inside]

Hyper-Yakety-Lapse
Instagram announced Hyperlapse - their new smoothed timelapse app for iOS (which is really cool). I felt it was lacking an 'add yakety-sax' button, so I went and created a bookmarklet to do just that.

An interactive explanation of quadtrees.
Because I was confused by them initially, I wrote an explanation of the concept of quadtrees (including some details about the D3 implementation of them), with some interactive elements that hopefully provide some hands-on stickiness. I tried to shoot for a non-programmer audience in the end. [more inside]

Learn programming with Reeborg
Reeborg's World, an adaptation of Karel the Robot, is designed to teach programming. At present, only Javascript is taught but a Python version is planned for the near future. By design, the progression is very slow but the aim is to cover almost all the basic features (and keywords) of Javascript using a Test-Driven Learning approach. Reeborg's World is free to use and does not require any login.

Generate images using an evolutionary algorithm by accepting or rejecting random images
This simple JavaScript game allows you to evolve a small image simply by accepting or rejecting random images, allowing them to "reproduce" into a new generation, and then winnowing down that generation to the "fittest" (ie, closest to your desired outcome) individuals. In other words, without drawing, you can--simply by accepting and rejecting images--create an image that you imagine.
Metropho.rs
Metropho.rs is a geographic metaphor map that plots "X is the Y of Z" tweets by putting the "Y" label on the "X" location. Some nice coverage by the Atlantic Cities blog here. [more inside]

Powershop.co
Powershop search engine for PC components (like motherboards, CPUs, etc). My basic plan was to create a tool like diskcompare that would work for all types of components, as well as an attempt to come up with a modern HTML5 UI that would let you view and filter data the same way you would in a spreadsheet or database browser. Right now it works for CPUs, GPUs, RAM, Motherboards, Monitors, Hard drives (including SSDs), USB sticks (and flash cards), Monitors, Cases and Fans, as well as Laptops and Tablets.
The front-end was done entirely in javascript (about 5k lines of JS before compression), and no HTML is generated server-side, instead plain HTML is sent and the javascript code requests JSON objects for everything else. [more inside]
