Orson R. L. Peters
Hi, nice to meet you, my name is Orson Raphael Lennard Peters. I am a programmer, computer scientist, recreational mathematician, amateur musician and general all-around nerd. I was born in 1994 in Houston, Texas, but both my parents are Dutch and I’ve essentially lived my entire life in the Netherlands as well.
If you are human you may contact me at
email@example.com, or alternatively on Discord at
orlp#012_, where the last digit is a zero.
While most of my projects live and die as a private prototype, over the years I did publish some things:
Pattern-defeating Quicksort, a sorting algorithm I invented and implemented in C++. Third party implementations of
pdqsortare used as the default unstable sorting algorithms in Rust and Go.
Glidesort, a stable sorting algorithm I invented and implemented in Rust up to ~4x faster than the default stable sorting algorithm for random data, and more for data with patterns. I presented glidesort at FOSDEM 2023.
slotmap, a Rust library for safely allocating and referring to objects in ways not encapsulated by lifetimes. Sometimes referred to as a (generational) arena or bump allocator, it uses versioned keys and slots to prevent use-after-free bugs.
peekread, a Rust library that allows you to peak ahead in a
Readstream using a cursor without consuming the original stream.
bunlink.vim, a Vim plugin that decouples the concept of ‘deleting a buffer’ from ‘closing a window’. This allows you to delete your buffers without destroying your windows/splits.
num-ord, a Rust library for correctly comparing built-in numeric types, in a mathematically correct way without overflows. This is trickier than it might seem, blog post pending.
I am interested in a lot of different things, including but not limited to sorting, hashing, hash tables/bloom filters, indexing, low-level optimization, compression, succinct data structures, error/erasure correction codes, programming language and algebra design, sound synthesis, encryption, quantum computing, distributed data structures and algorithms, actually… to save time, just assume I like most data structures and algorithms.
I like to cross the boundary between theory/research and application/engineering, solving hard problems, or not-so-hard problems with state-of-the-art solutions. Teaching others is also something I enjoy, having written 1400+ answers for a total of 110,000+ reputation on StackOverflow.
In my remaining free time I play classical and pop piano as well as a variety of video games, at least when I’m not busy being distracted by my two cats, Conway & Boole.
