Welcome to my personal site. Here you'll find links to various things I've created over the years.
My GitHub account. All of my open-source projects are here.
— A poor man's debugger for Python. Talk video
— A program that helps children learn
Python. Over 100,000 people downloaded this software, and I'm very happy I could help so many children get interested in programming.
— A Pythonic package for combinatorics.
— A collection of general-purpose Python tools.
— Useful extension scripts for the Git version control system.
I've contributed to lots of open-source projects: CPython, Django, Jax, Matplotlib, PyPy, Pandas and more.
Making 3d-prints stronger with titanium rods This is a technique that I've been using for years, and I thought I'd share it with the world. You can buy titanium rods for cheap and use them to reinforce your 3d-printed projects and make them stronger.
Live-coding a music synthesizer This is a fun live-coding session in which I explain how to write code that produces realistic-sounding musical notes.

Ram Rachum, born 1986. Born-and-raised Israeli. Python software developer. My name is pronounced /ʁam ʁaˈħum/
People sometimes find my internet nickname “cool-RR” odd. I assure you I am not a rapper. When I was a child in the 90's taking my first steps on the internet, I wanted to sign up to some chat website and my favorite nickname “RR” was taken. I went with “cool-RR” and I've been using it ever since.
