Lennart Augustsson is a Swedish computer scientist. He was formerly a lecturer at the Computing Science Department at Chalmers University of Technology. His research field is functional programming and implementations of functional programming languages.[1]
Augustsson has worked for Carlstedt Research and Technology, Sandburst, Credit Suisse, Standard Chartered Bank, Facebook, X Development, Google and is currently employed by Epic Games.[2]
Programming
Augustsson was intimately involved in early development of the multi-user dungeon (MUD) LPMud, both in the LPMUD driver and the CD mudlib. His MUD community pseudonym is Marvin.
He authored several hardware device drivers for the Berkeley Software Distribution (BSD) Unix operating system NetBSD.[3]
Languages
Augustsson has developed several programming languages and implementations, including:
- Cayenne[4]
- Haskell-B compiler (HBC)[5]
- Parallel Haskell (pH) compiler front end, from the Massachusetts Institute of Technology (MIT)[6]
- Bluespec compiler, first version[7]
- Lazy ML (LML), co-developed with Thomas Johnsson,[8] a functional programming language developed in the early 1980s, before Miranda and Haskell. LML is a strongly typed, statically scoped implementation of ML, with lazy evaluation. The key innovation of LML was to demonstrate how to compile a lazy functional language. Until then, lazy languages had been implemented via interpreted graph reduction. LML compiled to graph reduction machine (G-machine) code.[8]
Augustsson has written three winning entries in the language C for the International Obfuscated C Code Contest:
- 1985: Most obscure program (1985/august.c)
- 1986: Best complex task done in a complex way (1986/august.c)
- 1996: Best of Show (1996/august.c)
