I am blogging on jonathanfrech.wordpress.com, mainly about programming and poetry. Some highlights include:

• Slitherlink solver
• Haiku -- water droplet
• Lyapunov fractal
• Symbolic closed-form Fibonacci
• Asciify
• Tau day MMXVIII
• TImg

krrp

krrp is a functional turing complete esolang focussing on cryptic conciseness whilst preserving capability.
It currently has one interpreter, written in pure C.


Above krrp program calculates all primes below a hundred. Try it online!

Codegolf

Codegolfing in its purest form refers to the art of minimizing a program's byte count whilst still accomplishing some task.

I mainly golf on codegolf.stackexchange.com which is also home to other programming puzzles.
Some answers of mine include:

• Detect heat waves (C)
• Make Gimbap cutter (krrp)
• Life and Death of Trees (C / Python 2)
• Is the matrix centrosymmetric… and so is the code? (C)
• Generate TeX to typeset Sierpinski Triangle Fractal (C)
• When Fibonacci meets the Queens (Python 2)

OEIS

The On-Line Encyclopedia of Integer Sequences -- OEIS -- collects and curates integer sequences.
