Auctions, Beards, Conferences and Devils
It’s the last day of the most awesome linux.conf.au 2009 conference in Hobart, Tasmania. I’ve just witnessed the a room full of 500 people sit with baited breath as Linus wielded a set of clippers to shave Bdale Garbee‘s beard, followed by Bdale (with a razor with 3 more blades than last time he shaved, a tiny bowl of water and a hand-mirror) trying to make it look neater. The LCA twitter feed was up on the projector, and someone rightly observed this whole event was actually pretty weird. There are already pictures on flickr too. However, well done to Bdale for being such a good sport, but it looks like his wife Karen will accompany him next year to make sure he doesn’t agree to anything else like this, and supervise the waxing of Rusty‘s chest… 🙂
What’s this all in aid of? After the incredible auction for this beautiful picture from Karen, and generous donations at the Penguin Dinner on Wednesday night, the conference has now raised between AU$ 35k and 40k towards the Save the Tasmanian Devil appeal. Around AU$ 1.3k of the nonsensical winning consortium’s AU $10.6k bid came from the Collabora folks who were at the dinner, and AU$ 1.2k from Collabora and Collabora Multimedia directly. We were all set to place a winning AU$ 3k bid but then Matthew and Daniel came up with the Bdale shaving scheme, and then things really picked up. I’m glad we took part – the lead scientist from the project was really grateful, and I hope the money can make a real difference to their great work.
On more mundane matters, I also gave my talk this morning, and my slides (Telepathy slides v2.0 thanks to Marco) are online. I also made a few demos of new awesome stuff you can do with Telepathy (most of the patches are already merged upstream or well on the way):
- Geolocation support (XEP-0080) support in the XMPP backend and Empathy, using GeoClue to find your location and the libchamplain Clutter & Open Streetmap widget to display where your contacts are. Thanks to Pierre-Luc, Alban and Daf for their work here – more details on Pierre-Luc’s blog.
- Support for launching file transfers over link-local XMPP from Nautilus using the Empathy plugin for nautilus-sendto. This is already merged upstream but needs a patch to work with trunk Empathy. Thanks to Marco, Jonny and Guillaume for their work on this.
- Alban also made a neat hack to Rhythmbox which allows exporting your DAAP music server to one of your contants over a Telepathy Stream Tube. Thanks also to recent work from Marco, these tubes now go over XMPP’s SOCKS5 Bytestreams, giving much better throughput than the earlier in-band implementation, network permitting. The next step is unleashing the full might of our libnice NAT traversal library, signalling tubes with Jingle, and therefore making connections work peer to peer in up to 95% of the cases. However, this won’t affect the APIs, stuff will just go faster! Isn’t Telepathy wonderful?
- Olivier stepped up to show off the demo from his talk about Farsight, which shows his branch using the new telepathy-farsight library to allow recording Telepathy video calls directly into the PiTiVi video editor. His network was screwed up so it didn’t work, but I did see it work in his talk yesterday! Awesome stuff, hopefully Edward and friends can pick it up and merge it in before too long.
- Unfortunately we ran out of time for Will to show off Guillaume’s recent work on Telepathy-enabled Abiword on the desktop (rather than just Sugar’s Write activity), but I expect he’ll blog about it soon!
On that note, these were just the five that I picked to try and fit into my talk. There are a load more demos in the pipeline from the other guys in Collabora of doing stuff with Telepathy, so keep a close look on Planet Collabora for the next cool thing.

I’m sure someone has already thought of this and is already hacking on it, but… Pulseaudio + CELT + Exhibit + Stream Tubes + Empathy contacts. That would render me speechless, if not pantless.
So it exports an app and its sound? Hmmm… I think after the CELT talk this week, we’re going to hook it up in Farsight, which means we can put a mad high-definition low-latency RTP call up using Telepathy. As for Xzibit, we’ll have to see how Daniel gets on. If we have a call up alongside the app, mixing the app’s audio in isn’t unthinkable.
[…] lot of cool things happening at Collabora, and I’m really enjoying my work. I’ve been hacking on […]
will Telepathy ever support OTR (Off the record messaging)?
It’s not very straightforward due to Telepathy’s architecture. The best way we sketched out to do it was to have a kinda “proxy” Telepathy backend, which consumes OTR messages from the real text channel, and have a text channel that exposes the decoded messages to the UI. It’s not a huge priority to us (we’re more concerned with implementing XMPP’s upcoming standard for end to end encryption, for example) but we’ll be happy to help anyone who wants to hack at it.
