Identity pun

Sorry guys, this will make you cringe but I can’t help myself: this came out while I was reharsing a presentation just minutes ago. Ah, and you’ll get it only if you’re identity-sick 🙂 A passive client enters a shop, and starts looking around. A salesperson approaches: “Sir, can I help you?” And the passive client:…

Roles? Those are claiiiiiims!

[Warning: if you are not an identity geek, don’t read] People tend to approach new things by understanding how they relate with what they already know. That’s natural, and that’s also a very effective strategy: however it can only get you so far, and if you don’t start thinking out of the box/venture in uncharted…

On-premises, hosting & cloud: a metaphor for understanding how they differ

[Dear loyal readers, be warned: this post will contain some identity, but it is more about “pure” architecture & cloud services] On a flight Honolulu-Seattle; vacation is over, and I’m back to sharing with you my wild thoughts (ok, not ALL of my wild thoughts :-)). Have you noticed how people tend to react when…

Visual Studio web project template for Zermatt… and your CardSpace RP ASP.NET web site is up&running in just 37.1 seconds

You would not believe how often I have to set up identity enabled web sites: for verifying a theory, for proving a point with colleagues, for demos and events… really really often. Vast majority of cases those are barely proofs of concept, nothing elaborated, so I’ve been working for reducing the overhead that every project…

Claims propagation: Kirchhoff or maxflow?

In the last week or so Paul Madsen made at least a couple of posts with strong visual components: one that resumed my old 2005 post on a notation for message crypto, the other on Feynman diagrams. Nice! Paul, when I am in that mood I find especially pleasant to thumb through Tufte: I highly…

Voting for the Italian government election via mail

It’s that time again. Few months ago the Italian government fell, and as a good citizen I am called to the right-duty of casting my vote for electing the new one. There’s a little detail, though: while in the past that meant taking a short walk through my scenic little home town and meet few…

The Tao of Authentication (Part III – last)

(continues from Part I and Part II) Finally we’ve lined up all the elements we need for understanding how we can get rid of the 1-2-3 tyranny, and deal with our business requirements directly instead of relying on an old model that forces us to perform unnecessary steps and introduces artificial dependencies. For making sense…

The Tao of Authentication (Part II)

(continues from Part I) You can consider this post and the fine grained analysis we made in Part I as a down payment for grasping the implications we’ll see in Part III, which I plan to post in few hours (almost done). I was planning to have just 2 parts, but it came out far…

The Tao of Authentication (Part I)

From time to time it’s healthy to challenge the assumptions, and look at (allegedly) familiar things with new eyes. Few weeks ago I had to do just that with the idea of authentication: I wanted to shake a bit an audience of architects, and make them *think* about the problem instead of relying on the…

Understanding Windows CardSpace on the front page of Channel9

[edit: apologies if this shows in your aggregator twice. I am testing the AmazonConnect feed] Last week Caleb and I have been surprised in my office by Charles “Carlo” Torre and his camera. The result is an impromptu interview about CardSpace, which is currently on the front page of Channel9 (direct link here). If you have…
