Four Ton Fish

Hello 👋

My name is Stefan [stefn], and I'm a "full stack" web developer living in Brooklyn, New York. This site hosts my personal projects, blog, and tutorials. Some of my work is open sourced on GitHub. Sometimes I draw and take pictures.

My email is stefan​@fourtonfish​.com, and you can also find me on Twitter.

PS: This site runs on Pico.




In fact, it’s Stefan’s Twitter bot templates that power many of the Twitter apps on Glitch. His templates provide a useful springboard to the throngs of devs who are eager to quickly create a Twitter app or bot on Glitch, and they’ve already been remixed by more than 350 other app creators.

[...] here’s one of those tweaks, and it’s cool.

It’s called Simple Sharing Buttons Generator and it’s by Stefan Bohacek. Bohacek is Brooklyn famous for being the inventor of BotWiki, a digital encyclopedia of bots that can be found and used online.

Botwiki came about because Bohacek wanted to be able to run fast searches whenever he had an idea for a bot. As he explains, similar websites that already existed “were either a bit incomplete, hard to browse, or plainly just didn’t work most of the time.”

Stefan Bohacek decided he would catalog every bot on the web.

It’s no small task and he’s far from done. At his site, botwiki.org, you can search bots by category, by platform, or if you’re a dev and you want to learn how to make a bot, you can search by language or the text or data you want to use.

Botmakers.org provides a list of tools and resources for developers to create ethical bots, and the organization has a Code of Conduct that applies to all bots its more than 700 members create. Stefan Bohacek, Botmakers's organizer, said reaching outside of your usual social and professional circles to other groups can give you a different perspective and help you realize features your bot might need for harassment prevention.

Stefan teaches the web regularly and participates in our community of educators and activists. I appreciate his honest and constructive feedback and can-do spirit!

“As a self-taught web developer,” Stefan writes, “I really appreciate all the educational content freely available on the web. Many people devote their free time to create resources for anyone willing to learn, and I thought making this kit might be a way to contribute.”
