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 thank you drink :-) Note we are in the larger Chichester Room this month. Future meetings =============== Mon 20th April - Desktop Themes with Paolo Zaino and Martin Eastwood As desktop theming has been topical recently, Paolo will be talking about how it works and his theme application, and Martin will talk about the creation of his Frosted theme. Mon 18th May - ARX and the Acorn Palo Alto Research Centre, Jim Mitchell Jim Mitchell will be Zooming in from his home in California. Jim managed the ARM development team and was head of the Acorn Research Centre in Palo Alto, where the original planned (but failed) Archimedes operating system ARX was being developed. Very little has ever been heard about what happened there, so this is a unique chance to find out all about it. Before that he worked for 12 years at the legendary Xerox PARC where ethernet, laser printers, postscript, file sharing, and the WIMP concept were first developed. Later he worked for Sun and was responsible for the development of Java. He's a computing giant and we are very excited to have him joining us :-) https://en.wikipedia.org/wiki/James_G._Mitchell Directions to the venue by car (there is parking directly outside the pub on Coral Street) and public transport (recommended!) are on the website: https://rougol.jellybaby.net/venue.html Or contact us to receive the Zoom link to the meeting: https://rougol.jellybaby.net/contacts/ If you have attended any previous meeting, it's the same link this month.
