Tech Presentations

Thanks to Bill Clementson, I found out that I missed another OLPC technology presentation that was given by Ivan Krstić at Google Tech Talk.

Ivan talks about various interesting things in OLPC including their own approach to power management that reduced suspend time from 15 seconds (regular computers) to ~233 milliseconds (at the moment of presentation), file system with object store and unusual security requirements.

He also describes “View Source” button on keyboard – probably the first Open Source promotional tool of the kind.

See presentation on TechPresentations.org: One Laptop Per Child (Google Talk)

P.S. OLPC is running Give 1 Get 1 initiative that allows anyone to donate laptop to a child in development country and in return, get one for yourself. It just costs $400 for two laptops. Currently limited to US & Canada, but there are ways to get it elsewhere.

David Recordon made a good overview of problems and emerging technologies for open and distributed social networking from identity (OpenID, OAuth) to data interchange formats (XFN).

Video presentation by Douglas Crockford about history of networked computer interfaces and AJAX being the latest development but still far from being state of the art.

Another presentation by Douglas Crockford about JavaScript being a good language – despite the title of presentations, he looks at both good and bad parts of the language and describes how to go about using it.

A bit too cheesy marketing speech, but it introduces new technology and apparently MySpace and Google are behind it and all the huge crowd of other social networks like Ning, LinkedIn and SalesForce as well as application developers like Flixster, Slide and iLike.
