  • Year's end blabbering: Omnidirectional Identities

    On the Paris-Seattle flight, coming back after 2 weeks spent stuffing myself with all sorts of food with the excuse "after all, you can't find this in USA" :) Before hurling myself back in the vortex of daily work, and celebrate the end of the year with something crazy, I want to take some time writing down some hallucinatory (=vision without execution) thoughts about omnidirectional identities . Be warned, this may be just pointless rambling at this point. Few weeks ago I chatted about this in front of a microphone with John Udell , digressing along a crazy tangent instead of answering his questions about the book (I eventually came back to Earth and answered properly :)). I don't know if he'll deem those fragments publication worthy, but just in case I'll make a brain dump here. It's not that there's much more to do in this small seat anyway (just finished the latest Eco . He didn't mention underbite at all, I'm happy). Looking back at the activities related to identity in the past year, I am glad to report that amazing progress has been done. Something that makes 2007 very different from 2006 is the kind of work that was made: in 2007 the accent was on execution. The vision behind the metasystem is still being explored, sure, like Kim's series on linkage or the discussions about display token and first law demonstrate; and I feel that conjugating the metasystem and claims in enterprise environment is an area that still need focus (especially in fighting old forma mentis that Read More...
  • Can I have 2 Kg. of SOA?

    During this week in Singapore I visited many enterprise customers, and of course when you talk about WCF/WF/CardSpace the three letter word that begins with "S" and ends in "OA" eventually come up. For enphatizing my position "SOA is an Architecture, not a product" I adapted an old joke (is it an Italian joke? can't really remember) to the situation, and managed to draw some chuckles... so I'm grabbing my tablet pen and sharing it with you, hoping that my poor talent will be sufficient to get my point across. Enjoy & reuse :-) PS: OneNote totally rocks, even when misused for making silly pictures! Read More...
  • The Medley

    Almost one year ago the web space that was hosting all my blog images (since 2003) somehow lost all of them, so for about one year my past musings were nicely decorated by red "x" all over the place. This evening I finally took the time to go through old posts and see if I could find the images in some backups: fortunately it was the case, apart from 2 of them. I didn't realize how dependent I am from visuals for making my point: below there's a list of restorated posts that finally make sense again. Well, sort of. WS-Luggage . While unpacking from PDC03 a luggage slip stuck me as a phisical WS-Addressing header. The example went through! I didn't find the original image, so I scanned a new one from a different itinerary, hopefully the original point will be preserved nonetheless... WS-Trust - Considerations about the advantages of issued tokens over tokens derived from distributed material. One of the first posts in which I use the message security visual notation that came handy in the ws-trust video few weeks ago Artrage and Acrylic divertissments - hard to showcase a drawing software if you don't have a picture to display... Wingimcana , a little toy I wrote for leveraging the Toshiba M200 accelerometer. It was fun! End to end security - a metaphor for showing in practice what is the difference in expressive power between HTTPS and WS-Security Message Security Visual Notation - A first attempt to push the notation out. You may recognize the SAML diagram I draw during the channel9 Read More...
  • Please wait for your seat to reboot...

    In the last year I really spent an amazing amount of time on airplaines, flying around the globe to pursue my mission: evangelize, evangelize, evangelize! :-) A couple of times, always with the same airline, the onboard entertainment system showed a weird behaviour: first it slowed down dramatically, then it... rebooted. Once it even warned me ("please stand by as your seat is being rebooted": I looked worrily at the very chair, almost expecting it to fold on itself like in the SciFi channel pre-commercials), other times it went down without warnings. Well, while flying back from vacation thye actually announced on speaker that if the system is unresponsive one should wait 35-40 seconds (!!!) before clicking again on the controls, or a reboot would occur. As I didn't mention the airline, I won't mention the OS that rebooted; suffice to say that bluescreens didn't play a part in it ;-) Read More...
