Reinier, Cristiano and Melinda had visited Barcamp London a couple of weeks ago and Reinier gave a talk on Voluntary Economies which I helped him prepare.

Consuming Experience has kindly recorded this and a lot of other talks from Barcamp.

This is a rich topic and there is a lot to say about it. As I watch Reinier presenting it on the video, I see him explaining the examples we came up with and ideas pop up in my head of other examples, of how he could have told it better or how I would have told it differently.

Watching a video of a presentation you gave or helped prepare is immensely educational. I of course already ‘knew’ this, but usually it rewatching yourself present isn’t practiced very vigorously. This convinced me that it is completely worth it, probably time and time again.

As it will take a moment for Melinda, Reinier, Martijn, and Sjors to get to writing recaps of their talks, it might be interesting to notify you of some of the other people that have already written interesting stuff about BarcampLondon3.

• LondonBubble - The whole LondonBubble idea was based on the BerlinBlase idea that a few guys had during BarcampBerlin. They then acted as a group to do a live coverage of the Berlin event, and so now the same Germans including a few London locals decided to do the same here. I didn’t get to adding much to the blog or twitter feed, but I did cause for some inspirations.
• Tom Morris’ Videos - I think Tom was actually planning to do live streaming, but he never came to do it. He did put some stuff online eventually which can be found on his Blip.TV profile.
• Adam Cohen-Rose’s Blog - Adam wrote a lot about BarCampLondon3 and I think he did it while attending the talks. As a result it is not that much like an actual blog and more like quick note taking sessions of every talk. Still, handy as a reference.
• Kerry Buckley - Kerry did something similar as Adam, but a bit less note-like and therefore more readable.
• Slideshow of the most interesting photos on Flickr.
• Video of Andy Budd on a Segway - Funny to watch. I actually got to drive the thing too and damn it was easy. Very impressed by the device.

I didn’t take that many photos this weekend at BarcampLondon3. Somehow photographing the same geeks over and over again becomes annoying (and they get annoyed with you). I did have fun though by actually listening to people. Hope you enjoy the photos and maybe find yourself in some.

Last weekend it was time for the third Barcamp here in London, a.k.a. BarcampLondon3. The location was the beautiful Google Office in London and the organization was brilliant (thank you Ian!). Besides all the nice food, the games of Werewolf, and riding the Google Segway, we also had some moments to present our talks. I actually knew what to present before I went, which made it easier to follow some of the other talks going on without the need to build on my own presentation.

At BarcampBerlin2 I had spoken about Yahoo Pipes and noticed that not too many people knew about Yahoo Pipes at all. Many people that had missed my talk there happened to be attending the Barcamp in London and so I decided to hold the same talk, but presenting it is as more of a walk-through/hints-and-tips session. It turned out to become quite an interesting session, with people ranging from newbies on the topic to people like Ian Forrester that I had a discussion with on the practical uses of Pipes and what was needed to make it realy handy as a tool for commercial developers.

I don’t have slides except for these here which I used at Barcamp Berlin, but lucky for you Tom Morris has recorded my talk on video. The quality is not brilliant and sadly you can’t see what is on the screen, but if you use my previous post on Yahoo Pipes and the slideshow as a reference I think it can be interesting to watch.

This article was originally posted on 23 November 2007 on Cristiano’s own blog. This article is technical but not necessarily complete on the details, keep that in mind. Further more, this article served as the basis for Cristiano’s BarcampLondon3 talk.

So, as you might have noticed I build my own little copy of a Lifestream, much like Jeremy Keith (Adactio) did on his website. Although it is fun to build a lifestream, it isn’t the simplest thing to do, so I took a different approach to use mine and build one using Yahoo Pipes.

The cool thing of using Yahoo Pipes is that my Lifestream is all Javascript+HTML and no server side logic (a.k.a. PHP). I gave a little talk during BarcampBerlin2 explaining what I did, but in the next few paragraphs I will hopefully explain with a bit more detail how it was exactly done, and also focus on some quirks of Yahoo Pipes that I had to work around.
