Glyph
@[email protected]he/him
You probably heard about me because I am the founder of the Twisted python networking engine open source project. But I’m also the author and maintainer of several other smaller projects, a writer and public speaker about software and the things software affects (i.e.: everything), and a productivity nerd due to my ADHD. I also post a lot about politics; I’d personally prefer to be apolitical but unfortunately the global rising tide of revanchist fascism is kind of dangerous to ignore.
