This Sunday I went to OLPC Pune meet to give a talk on activity development. The students seem be very enthusiastic. The talk lasted for around 2 hours. Photos can be found here.
On the other side, I was looking for a photo catalogue software which can catalogue my photos on DVD or any other removable media, it should also allow me to search them based on EXIF data and tags and should show thumbnail(s) in the result. I generally use digikam and gthumb too manage and view the photos. In digikam I never being properly able to catalogue photos on DVD (never tried on the last few updates) and gthumb is too slow in showing the thumbnail or full screen views for the large size photos I take. I prefer gthumb over over digikam to view the photos due to the simpler UI.
Finally decided to write my own app for this, which will not have any editing features, Gimp is the tool I use for editing. Watch this video (3.2MB) and please comment if the thumbnail creation / viewing is fast or not ?
