I was born in 1958.
I am a self-taught programmer with a passion for developing (in C) fast programs handling huge volumes efficiently. These programs may or may not be multi-threaded but, if they are, they will be reasonably in harmony with at least the L1 cache.
I have been a fan of shellsort for more than ten years.
I am also a fan of access routines (in C) for hash tables.
I live in Stockholm, Sweden
