Interact With Your Media

Friday, June 6th, 2008

Recent developments allow video producers to add Java script to their movies. Users can therefore be asked questions and, based on their answers, redirected to different content. See a small shell game example here. I guess the only unfortunate thing about the whole experience is that each click requires a full page to be loaded- the interaction is far from seamless.

Or, if you don’t like that, you can use your mobile to make some popcorn.

On Twitter’s business model

Thursday, June 5th, 2008

Interesting article in today’s Guardian. “Twitter users are increasingly inured to outages. … Why? … every new tweet (a single message) gets written on to one MySQL database; that is then replicated to multiple slave databases, from which all the “reads” are taken” (more).

What Twitter needs is to expand its capacity while making money from those who are using it. … it needs to deter some people from using it – while benefiting from those who continue to. There are two obvious ways forward. Charge the users, or charge those who want to get at the users. The first option is fine – if it wants to lose 90% of its user base (the rough tradeoff any service sees if it begins charging, however little). The second option might look puzzling, but it has worked before, in the MP3 market.

Perst Lite embedded database for Java ME upgraded

Wednesday, June 4th, 2008

“If you’re developing applications for Java-ME (J2ME)-based mobile device, and writing your own data management code, you should check out the Perst Lite open source, object-oriented embedded database from McObject ( …  Since coding a database management system from scratch is no easy job, it makes sense to look at Perst Lite before you “re-invent the wheel” of database capabilities for your next Java ME software project.

You can freely download complete Perst and Perst Lite package. Complete documentation is available here (scroll down).” FromTed Kenney (McObject,

Location-enabled Mobile Browser

Tuesday, June 3rd, 2008

Christian Becker‘s presentation about DBpedia mobile (pdf): a location-enabled linked data browser for mobile devices, giving you nearby sights and detailed descriptions, restaurants, hotels, etc. We chatted a bit after the workshop with Alexandre and Christian about adding events to the DBtune exporter to also display nearby gigs (with optional filtering based on your foaf:interests, of course :-) )”

Homophily of social ties

Tuesday, June 3rd, 2008

“I always learn something when I teach my networks class. One of the early exercises that I have students do is a personal network self evaluation (adapted from Baker’s book on social capital). The students’ networks tend to be highly educated, very international, ages 25-30. Essentially, the networks of students tend to look a lot like themselves. What is notable (I base this on the last 3 years of doing this exercise) is where the networks look most different from the students, which is, more often than not, in ties to family members. Family ties are somewhat less likely to be highly educated, and when they are, it is often in a different domain than that of the other people in the students’ network, and, unsurprisingly, they are often (literally) of a different generation.” More.
