Richard Barrell

Hi, I'm Richard.

I write computer programs.

My C.V. is linked above. The really brief summary is that I can write useful programs using Python, 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. I am surprisingly optimistic.

Contact me:

• By email, if you'd like to arrange a call.
• On LinkedIn, if you prefer that.
• Github is where I share some of the software I write.
• I'm often on freenode under the name "RchrdB".

Blog posts:

• Customer support 101 for SMEs that sell software
• Logging messages onto a strictly bounded queue is perilous
• Recording game videos with ShadowPlay and ffmpeg
• Zero-copy? How about three?
• Four dumb questions I'd like to ask hardware designers

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.
