I presented this talk at BarCamp Ireland 3 on April 21, 2007.

There was a lot of interest and we had to move to a bigger room to accomodate all the audience (thanks to Ryan Alexander for arranging the bigger room).

PowerPoint file: "SIOC - Semantic Web for Social Media Sites" (6 Mb, PPT)
If you watch the presentation on SlideShare the hyperlinks should work as well.

Olivier Ansaldi (in comments to an earlier post):

"I really enjoyed your talk (just in case you remember, I asked you a question about microformats), it helped me get a better understanding of the semantic web. I feel more inclined to start digging in the literature that I felt before!"

If you were at the presentation and have some questions about it, please ask. Literature is one place to start, but at the same time you can try to work with the Semantic Web and RDF, and judge for yourself when and where to apply it.

This is a crop of a larger photo. I saw a Flickr group once where you can post a photo and people try different ways to crop it. Can't find it any more - there're too many groups. Can anyone remind what is this group called?

Like the eyes in this shot. Maybe crop more and leave just the eyes?

"Lunar eclipse wows sky watchers" [BBC News]

About this shot:

Taken with a Canon SLR and a zoom lens at 300mm, then cropped to show a close-up view.

Hope you like it. This is the moon during a total eclipse.

A short line in the center of the photo is a star - you can see how far it has moved through the sky during an 8 sec exposure. Would have been happy to get a sharper picture, but this was the best I could. The moon also moves through the sky and one would need a shorter exposure and maybe a better lens to get a sharper photo.

"Lunar Eclipse" - the same photo on Flickr.

This is a presentation about XUL and Mozilla Application Framework.

Presented it at DERI Reading group some time ago. Now putting some slides online and this is the first of them.

[ XUL + RDF + JavaScript + CSS ] forms a framework used to build all Mozilla applications and Firefox, SeaMonkey, Thunderbird, ... extensions. There is also XBL and XPCOM for more demanding applications. It is interesting that this framework is one of first widespread uses of RDF (even though you might not be aware that it has RDF under the hood).

More resources as a followup to an earlier post about "Photoshop Channel Chops" book:

If you can't find the book, which is a real education if you have not used these, you may want to start with perhaps the oldest tips for Photoshop: Kai's Power Tips [1]. These were a forerunner to Kai's power Tools, back in the days of Photoshop 2, I think. They use channel operations extensively. Although it is all VERY out of date, and seems somewhat ordinary compared with the present tools, it will explain the thinking somewhat. Really the best way is to jump right in. They are now called Calculations (Image menu) and they names have changed and new options are now available.
