About me

My name is Ján Sučan. I am a programmer.

For me, programming is sharing ideas. Not only to the computer and the users, but also to other programmers and my future self.

The ultimate goal I strive to achieve is clarity. Clarity shares ideas. Clear software is easy to understand, verify, extend, and fix.

I love reading books and learning new things. Currently, I'm learning functional programming, Haskell, and Lisp programming languages.

“Interviewer: You seem to scorn complexity. When you design a system, do you strive for simplicity?

Lampson: Right. Everything should be made as simple as possible. But to do that you have to master complexity.”

Butler Lampson for the Programmers at Work

My work

All my projects have available source code. You can find them in my GitHub profile.

Contributions to open-source projects

Trinity Desktop Environment, various small fixes and improvements.
Xfce Desktop Environment, maintained xfce4-mailwatch-plugin and released a new version.
FreeBSD, optimized the restore utility to make it faster by saving unnecessary system calls when restoring large sparse files.
DragonFly BSD, unified handling of firmware with the rest of the system for some drivers.

Google Summer of Code

I was a successful Google Summer of Code 2019 participant with FreeBSD. I was working on a new dual-stack ping command which would support IPv4 and IPv6 in a single utility. The goals were to merge ping6 utility into ping while keeping the output unchanged and to remove duplication of the code.

Magazine articles

The articles were published in Czech magazine Praktická elektronika - Amatérské Radio (Practical Electronics - Amateur Radio). They are written in Slovak language; the magazine started publishing in Czechoslovakia in 1952.
