Richard Barrell

Hi, I'm Richard.

I write computer programs. I can write useful programs using Python, TypeScript (or JavaScript), C and Linux pretty much with my eyes closed, plus also I can do a lot of other things with varying degrees of familiarity. I enjoy debugging.

Contact me:

• I'm on Mastodon at @0x2ba22e11@unstable.systems.
• I'm on LinkedIn.
• I share some of the software I write on Github.
• I'm on Twitch.

Blog posts:

• Static types and shovels
• Connection pools must propagate connection errors
• Customer support 101 for SMEs that sell software
• Logging messages onto a strictly bounded queue is perilous
• Recording game videos with ShadowPlay and ffmpeg

WebGL fractals:

• Cyclic cellular automaton. It's a cellular automaton (like the Game of Life is) with an update rule that tends to make it cycle, seeded with random noise. Try turning the number of states up past 16 and making it really big.
• Mandelbröt with continuous colours and animated center coordinate changes. It wibbles and you can control how much with a slider. Also there's now a slider that interpolates between Mandelbröt and the burning ship.
• Julia with continuous colours instead of discrete bands.
• Julia fractal.
• Mandelbröt fractal.
