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

krrp

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

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:

OEIS

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

My most recent contribution to the OEIS is sequence A325902:

Numbers whose neighbor's prime factors with multiplicity can be partitioned into two multisets of equal sum.
