Tony Hoare will open with a 10 minute summary of language features proposed during his career. Each feature was motivated by the desire to reduce the range of programming errors by increasing the range of errors discovered at compile-time and ensuring that those which slip through can be detected and isolated at run-time. Then he and Bruce Tate will introduce the panel and ask the language inventors to give a five minute introduction of their language answering questions like:
* Was ease of writing correct programs and debugging incorrect ones important to the market segment (ecological niche) at which your language was aimed?
* Which particular features of your language met this goal, or tried and failed?
* For what features was correctness sacrificed in the pursuit of alternative goals – eg. compactness, familiarity, compatibility, efficiency, etc?
* In the light of hindsight, what would you have done differently, and why or why not?
This will be followed by a discussion amongst inventors of languages such as F#, Erlang and Hack.
Joe Armstrong is the principle inventor of the Erlang programming Language and coined the term "Concurrency Oriented Programming". He has worked for Ericsson where he developed Erlang and was chief architect of the Erlang/OTP system. In 1998 he left Ericsson to form Bluetail, a company which developed all its products in Erlang. In 2003 he obtained his PhD from the Royal Institute of Technology, Stockholm. The title of his thesis was "Making reliable distributed systems in the presence of software errors." Today he is semi-retired but works part time as Adjunct Professor of Computer Science at the Royal Institute of Technology in Stockholm.
