My book’s been for sale over a year now. It was written back in 2006 and released in 2007. I fully expected the whole "Mashup" craze to be over and done with at this point. Here we are in 2008 and I’m still hearing folks touting this as "cutting edge". The latest evidence came this week actually when a vendor presented their "web 2.0" capability as if we’d never heard of it.
Writing a book is fairly rewarding. Just the satisfaction of seeing the words you’ve toiled over printed and bound …

I’m a bit late with this one….Shamelessly copied from Axel’s blog [LINK]

Showcasing How Users Can Control their Identity Online, Industry’s Largest Identity Interoperability Demonstration Scheduled for RSA 2008
Fifty-seven member open source identity group to test and demonstrate interoperability between user-centric identity protocols and providers
SAN FRANCISCO (RSA Conference 2008) – April 7, 2008 – Open Source Identity Systems (OSIS) will conduct the largest user-centric identity interoperability test and demonstration at the 2008 RSA Conference, April 7-11 at the Moscone Center in San Francisco. The 33 member …

As the Arduino only supports 14 output digital pins, I ordered some shift registers a while back from eBay. They took 7 days to arrive but are finally here.
As a small project to get my feet wet with serial/parallel output, shift registers etc. I’ve set about building a 25 (5×5) RGB LED matrix display. I may extend it in the future to 7×5 for larger fonts.
I’m using circuit board from RadioShack to which I’m soldering the LEDs. I intend on using breadboard for the chips until I get …

Preliminary interoperability testing results of my Identity Provider [LINK] with other Relying Parties yield 5 Failures, 8 Working exchanges and 4 Not Applicables.
It’s a beautiful thing when the RP and IdP just "work". Checkout the results here [LINK].
For a semi-homegrown solution I’d say that’s not bad. Maybe instead of "trusting" someone with my valuable identity information, I can just be my OWN identity provider?

Cardspace can currently be launched from a web page through the use of the object tag, html form and optionally some javascript.  This approach requires rendering an HTML page and some form of user interaction before the Cardspace ID selector is launched.
This works for the typical case of logging into a website, establishing a session and accessing protected web pages.
But what if you just want to protect a file. Or an XML resource like an RSS feed?
In this post I’ll propose an extension which would allow Cardspace …

Tonight I launched a simple CardSpace Managed Card Generator and Test Harness. It lets you generate a managed card, with whatever claims you’d like and then generate a test harness form for that card.
The card can then be used to obtain claims from a Simple Security Token Service. Lastly, these claims can be consumed and parsed out to complete the end to end process.
This might seem like a trivial exercise but I have not come across any other publicly available service that demonstrates the end to end flow …

Before I forget; Today I took a call with Olga Kharif from BusinessWeek [LINK]. She’s doing a piece on social networking and Google, specifically Orkut. I doubt I’ll be quoted but will watch out for the article in any case. Here’s a link to the last time [LINK] I was interviewed by her colleague Robert Hof [LINK].

I have made a tool, that indexes Flickr Creative Commons photos and performs some mathematical analysis on same. The results are stored in a database.
It then takes an input image, slices it up into tiles and matches these tiles with the closet image in the database. Due to the nature of the analysis done up front, large tiles can be used rather than individual pixels.
The entropy of the tiles is much greater than individual pixels, this yields a more realistic image in a smaller size than matching …

This website is primarily for my own gratification and rarely do I presume to think that it’s a valuable source of information. On the other hand, I do occasionally put forth the odd interesting nugget of information that you won’t generally find elsewhere.
Hence it’s always gratifying to come across websites that link to mine as a point of reference. Today I came across two such instances. The first is Wikipedia on their Live USB page [LINK] referencing my post on how to install and boot Linux from a Creative …

I’ve done some multi-threading programming the last week or so for fun. Here’s the result:

This picture is made up of a few thousand photos, selected from a repository of 35,000. No image is repeated in the collage. I think I’ll make a few more when I get a spare minute. If you’d like one made for yourself, let me know.
