IRFS Weeknotes #168
This week IRFS ran a Cross Platform Authentication demonstration in Geneva whilst the latest laser-cut Radiodan enclosure took shape back in London.
This week, Michael and Sean showed our reference implementation of the EBU Cross Platform Authentication protocol working with a real Internet-connected radio at the EBU RadioHack event. The implementation supports the Authentication Provider, Service Provider and Client elements. The team are now focusing on the CPA protocol specification document, to identify and resolve any issues in the current draft.
Libby has been continuing a review and exploration of Device Pairing, producing a lot of strange beeping noises with the Web Audio API which she also used to capture and visualise the frequency and amplitude. With help from Chris N she has put together a document about discovery and pairing which is open for comments and contributions. A blog post and open source code to follow shortly.
Andrew and Dan spent this week adding the multitude of actions that make a music player useful to Radiodan, including player actions (volume setting, pausing and skipping tracks), playlists (adding, removing and reordering) and searching for tracks to play. Now the server is close to being useful they are working on making it runnable as a stand-alone service, possibly wrapping it into a Debian package for rapid deployment to Radiodans.
Letter from America
Zillah has got the go-ahead to restore and publish over 280 "Letter from America" programmes from the 1970s, recorded by a dairy farmer from the Cotswolds and stored in his cellar! Radio 4 Extra will have a special 2 hour programme on the 30th March, presented by Paddy O'Connell, playing excerpts from the programmes and discussing the themes and stories. The programme will mark the 10th anniversary of Alistair Cooke's death.
Cloud Marketplace for Media Analysis
The COMMA project is working towards the idea of an "immutable infrastructure", which is essentially means that we never update our stack on Amazon and instead replace it entirely with every new release. Matt is working on integration testing and preparing a forthcoming blog post.
Yves spent quite some time working with the word2vec algorithm and contributed code to the Python implementation of this algorithm in Gensim. He's investigating it as an alternative to RDFspace for COMMA-related algorithms. He trained a model on the whole of Wikipedia, which gave very good results but took a while to build! The aim is to introduce subject tags in our Mango automated tagging tool.
Finally Olivier, Tim, and other members of IRFS attended an evening of sketching techniques where we refined our abilities to rapidly move thoughts onto paper.
