FilamentColors.xyz
In 3D printing, getting the right color of filament for a project is often a pain. Have you ever wondered “what filament do I need to get to match this color?” or “what looks good with this filament I already have?” These are questions FilamentColors.xyz tries to answer by providing a filament color database with over a thousand different filaments from all over the world – each one printed, measured, and automatically grouped into pre-built color palettes ready for you to use in your next project!
Grafeas Group, Ltd
A small international nonprofit that I co-founded with James Coe, this registered 501(c)3 in the US has over 5,875 volunteers and aims to increase accessibility on the internet. By creating text versions of internet content, everyone has a chance to participate in the discussion. Our volunteers have, at the time of this writing, completed over 270,000 transcriptions and descriptions online and through Reddit for those who need them.
The organization uses six bots total; three on Reddit’s side and three internal bots for managing ourselves and our community.
Grafeas: The External Bots
u/transcribersofreddit
The primary bot that volunteers interact with, this bot is responsible for finding new content, posting it to the subreddit, and working with volunteers as they complete transcription jobs. This is the first bot that I wrote for the project, and the very first version was knocked out in my airb&b room in between PyCon sessions in 2017!
u/transcribot
Sometimes it’s helpful to have a starting point for some of the longer transcriptions, so u/transcribot runs each and every picture through OCR and posts the (often hilariously wrong) results where the volunteers can access them. It follows u/transcribersofreddit around our subreddit, toddling along and trying its best.
u/ToR_Archivist
Arguably the least-known of the trio, the Archivist takes completed posts, grabs the link to the actual completed transcription, and posts it to the TranscribersOfReddit Archive for folks who need it. It also removes posts from the primary job board as they ‘age out’ if no one claims them.
Grafeas: The Internal Bots
Blossom
The Django monolith that powers it all and the keeper of our data! Blossom is where all of our central processing takes place; the other five bots make very few decisions for themselves and mostly look to Blossom for guidance. Blossom also powers the organization homepage, grafeas.org!
Bubbles
Every organization needs an overly chatty chatbot, and Grafeas is no different. Bubbles runs in our internal Slack and assists with anything we need – anything from gathering data on potential subreddits to providing pictures of cute animals to handling our deployments of all six bots (including herself!) to production!
Buttercup
Buttercup runs our volunteer Discord! Host to a whole bunch of cool commands and data visualization stuff, Buttercup helps enforce username standards and also allows volunteers to track their progress on various challenges and get access to other cool data to see how they’re doing.
Grafeas: The Other Stuff
Occasionally we work on other systems as we prototype ideas or spin out functionality into other repositories as needed.
Utonium
As we grew Bubbles, we realized quickly that the slack-bolt package that Bubbles used was not really designed to handle all the commands that Bubbles has, so I designed a plugin system from the ground up to handle the (vaguely ridiculous) number of Slack commands that we need to handle across different platforms. It’s not the easiest to integrate, but works well for our needs!
Caroline
An idea that we toyed around with for using Redis or Elasticsearch as a pseudo-relational backend that relies on JSON Schema for validation. Still a project that I’m quite proud of, even though I’m not sure it should ever actually be used.
asbestos
At SpotOn, we work with a lot of data in Snowflake but there is was no way to mock the connection cleanly for testing functions that use Snowflake data or for developing against a Snowflake call and paying to run the same query over and over. Enter asbestos, a project named after the fake snow from The Wizard of Oz. (That’s true: the snow used in the movie is 100% pure asbestos. Horrifying, isn’t it?) Asbestos allows you to mock the Snowflake connection, store SQL queries and expected answers, and then spit back the answers when you call Snowflake normally.
Fun fact: the original name for this project was snowfake, but Snowflake’s lawyers told us we couldn’t do that. ðŸ˜
emailmagic
mailto: links are annoying, and it’s weird to me that we don’t have an industry solution to this problem yet. emailmagic watches for mailto: links, then makes the link pop up a modal so you can open the link in your preferred email client or just use the default browser behavior. On the sites that I write myself (e.g. not this one), I use Bootstrap as my UI library of choice so that I don’t have to reimplement everything from scratch, and emailmagic is styled using Bootstrap 5 so that it can be a clean drop-in addition. See the readme for more information.
What day is it?
Have you ever wished that you had a very specific yet startlingly useless way of identifying what day it is? Do I have the answer for you…!
Yarn Calc-inator
A basic meters <-> yards conversion tool for identifying how many skeins of yarn you need to purchase for a pattern if the measurements are different or the amount of yarn in each skein is different. Written for my partner to aid in her crochet projects.
