ABOUT ROUGOL
ROUGOL is a not-for-profit organisation consisting of Acorn/RISC OS computer users in London and the south-east. Our aim is to bring those users together. There is no membership fee and entry to all meetings is free. To find out more, email us.
MEETINGS
Meetings are held on the third Monday of every month. Most meetings feature a guest speaker, demonstrating the latest hardware or software, giving tutorials of software both new and old, or simply to kick off discussions on the current hot topic. Entrance is free, so why not come along and say hello?

JSbeeb and Compiler Explorer - Matt Godbolt
Matt Godbolt has a computing story that will be familiar, starting programming on a Spectrum before upgrading to a BBC Master and then an Archimedes, finally moving on to PCs. Having written for Acorn User and produced Beeb games as a teenager, he then wrote RISC OS software such as IRClient and FinalLook while at university, before going on to work for Argonaut Games, Google, and many more.
These days Matt is known in the retro computing world for producing JSbeeb, the BBC Micro emulator in Javascript which powers the Complete BBC Micro Games Archive, enabling every Beeb game to be played live in you browser. (He has also done a Spectrum emulator, but we don't talk about that!)
Outside of retro circles, Matt's major public project is the Compiler Explorer website, which enables the live analysis of the output of many different compilers to see how they optimise code.
Matt is visiting London from his home in Chicago and will be joining us
in the pub to talk about some/all/none of this and more! Come along
to chat to him and maybe buy him a thankyou drink :-)
