BlogFest in Riva del Garda, 12-14 September 2008

Blogfest Wow, there will be a great blogfest in Riva del Garda on 12, 13, 14 September 2008!
Since it is very close to Trento, I’ll be able to attend all of it, great!
The Web site is at Blogfest.it and I really suggest you to come to Riva del Garda (a gorgeous small city!) and keep an eye on the blogfest. There will also be also 3 simultaneous Barcamps! I’ll post more details when the date is a little bit closer.
See you in Riva in September!

Calvino’s invible cities and their web of relationships


(Image from Maggie Digital, released under Creative Commons BY-NC-ND)

Quote from Calvino’s Invisible Cities

In Ersilia, to establish the relationships that sustain the city’s life, the inhabitants stretch strings from the corners of the houses, white or black or gray or black-and-white according to whether they mark a relationdhip of blood, of trade, authority, agency. When the strings become so numerous that you can no longer pass among them, the inhabitants leave: the houses are dismantled; only the strings and their supports remain.
From a mountainside, camping with their household goods, Ersilia’s refugees look at the labyrinth of taut strings and poles that rise in the plain. That is the city of Ersilia still, and they are nothing.
They rebuild Ersilia elsewhere. They weave a similar pattern of strings which they would like to be more complex and at the same time more regular than the other. Then they abandon it and take themselves and their houses still farther away.
Thus, when traveling in the territory of Ersilia, you come upon the ruins of abandoned cities, without the walls which do not last, without the bones of the dead which the wind rolls away: spiderwebs of intricate relationships seeking a form.

The Global Gender Gap Report 2007. Italy? 84th out of 128

The Global Gender Gap Report 2007 is out.
Sweden (1), Norway (2), Finland (3) and Iceland (4) once again top the rankings in the latest Global Gender Gap Report. The Report covers a total of 128 countries.
Ah yes, you are wondering about Italy? Why really wondering? Anything else to do? Uhm, ok here is the raw reality: Italy is 84th out of 128.
Our cousins of Spain are 10th (!), Latvia is in position 13 and Lithuania 14. Moldova is 21, Cuba is 22, Colombia is 24, Bulgaria is 25, Lesotho is 26, Namibia is 29, Tanzania is 34, Vietnam is 42, Romania is 47, Uganda is 50, Botswana is 53, Albania is 66, China is 73
Did I say that if you scroll down down in the list you find Italy in position 84?
So why cannot an NGO of Lesotho comes in Italy to help us with an international cooperation project about gender issues?

Report from the Information Architecture summit (day 2)

After the first day, there was the second day. Yes, yes, I was surprised as well.

I overslept a bit and I miss the first talk, sorry.
The second one was titled “The Web2Architect” and given by Chris Addison, Antonella Pastore, Pier Andrea Pirani. They work for Euforic which is an organization that is actively trying to push adoption of web2.0 tools in international cooperation organizations and so I was very very interested because I’m actually helping a local NGO with this.
Actually the talk was partially ruined by the fact the lamp of the projector was totally going to die and the slides could just be intuited behind a black veil, very unfortunate, especially because it was another fancy, very visual presentation. Anyway they basically shown us how they use all the web2.0 instruments (del.icou.us, blogger, flickr, slideshare, blip.tv, pbwiki, google calendar (and all the other services by Google), facebook, …) in an integrated way for their work. It was not extremely unexpected since I guess most of the people in the audience already knew all the services but it was good to get an overall view (and a lot of pointers I should add! “euforic” is on dozens of different social sites!!!). I think they somehow failed to summarize their message at the end. I guess their point was something like “information architecture for us is just reuse existing services, nothing more” but they didn’t make it clear which is a pity since the conference was about “information architecture”.

Another extremely interesting talk was given by Dario Betti and Stefano Bussolon and was about “La classificazione fatta dai cittadini. Il caso Trentinosociale.it”. They told us how they worked through the (re)creation of Trentinosociale.it, a portal for the welfare wanted by the local government.
I liked the suggestion we should speak about stakeholders and not users, since one of the goal is that stakeholders feel the project as their own project. They used the cardsorting technique, with an online tool called Netsorting developed by Stefano Bussolon as part of his phd thesis in sociology at the University of Trento. I really need to dig a bit more into this instrument. The overall goal of the redesign was to let the lexicon and the structure used in the site come from users, in order to give the stakeholders what they really want.
They collected a very large number of feedback reports from users and based on this they were able to redesign the site. Very interesting!

Another intersting talk was given by Michele Iovino “Hardware Hacks e Context-awareness”. He introduced projects such as arduino, processing, wiring and in general the concepts of open hardware.

The Closing keynote titled “The DIY Future: What Happens When Everyone Is A Designer?” was by Joe Lamantia. Another fancy presentation. I didn’t get his main points but I have to admit I was too tired to follow it.

At the end there was the 5 minutes madness session: the microphone was placed on the table and everyone was free to pick it up and speak, about the conference, about the topic, about anything. Some crazy/funny things arose such as “la corazzata Potemkin e’ una cagata pazzesca” (if you are not Italian, you cannot understand this, it is from a Fantozzi movie) and the Buttered cat paradox. There was an applause after every short intervention … so it was not too much madness but it was a very very interesting modality for ending a summary anyway.

A final short point about the summit. I think there were 2 extremes in presentation: one axis was about presentation style, the other was about reality groundness. About presentation style, some presentations were very intriguing and fancy (lots of cool full screen images and lots of single word slides and black background, presenters moving around, making jokes, changing tone) while the rest was very boring (white background, lots of text, presenters never moving, not changing the tone of voice). Unfortunately I think I’m much more a presenter of the second type so next time I’ll try to create a fancy presentation. Anyway I’m not sure that fancy presentations are really that good for conveying concepts to the public: while a boring presentation does not convey any concept (simply because the target is not following it but doing something else (browsing, sleeping, …)), a fancy one might amuse the public but at the end the viewer might be in the state “funny, 30 good minutes, but what was the message?”.
About reality groundness, I have to admit that academics usually propose things that will never ever see any application in reality simply because they are too … uhm … unrealistic, while entrepreneurs and consultants have to propose something that works, now, and so they focus on reality, but I guess this is not a surprise for anyone. I prefer the reality grounded approach, expecially if the topic is information architecture.

Closing, I should really thank the organizers for giving me the opportunity to assist to such a diverse and thriving summit. Thanks to Alberto Mucignat, Emanuele Quintarelli, Andrea Resmini, Luca Rosati.
Also I liked a lot the idea of using a kitchen timer (shaped like a tomato) for setting the time for presentation. It was friendly, funny and ice-breaking, but still very very strict in keeping the speakers on time, I think I’ll borrow the idea if I ever get the will of organizing a (un)conference or similar.

I think I’ve learn a lot from this summit.

Recommender Systems conference in Minneapolis

I’ll be in Minneapolis for the Recommender Systems 2007 from October 18th until October 22nd presenting a paper titled Trust-aware Recommender Systems which is a summary of a part of my PhD thesis. I’ll be hosted by Renee, couchsurfing as usual. If you are around and would like to discuss anything, let me know, k? See you soon, on the other side of the pond!

The end of corruption, brought to you by Lawrence Lessig and powered by millions of us

Lawrence Lessig is a genious. He decided to dedicate the next 10 years on ending corruption (after spending the past 10 years on reframing copyright issues), there is really an hope that a vast movement will self-aggregate around him and got an unstoppable momentum. After watching his tv interview (embedded below), I’m really optimistic a solution to this plague can be found.

Reputation is in the eye of the beholder: on subjectivity and objectivity of trust statements

I eventually managed to get invited to the ENISA Workshop “Security Issues in Reputation Systems” and at the eema’s “The European e-identity conference”. So I’ll be in Paris from Monday 11 until Wednesday 13, of course hosted by friendly Couchsurfers. The program is quite interesting, I’m especially looking forward for the keynote address by Kim Cameron, whose blog I’ve been reading since some time, and a presentation by Alessandro Acquisti of CMU titled “Imagined communities: awareness, information sharing and privacy: the Facebook case”
Let me know if you’ll be there, I’ll be happy to discuss about trust, reputation, identity, whatever.
Since I was required to provide a position paper, I put up the following, the intention was to be a little provocative but I don’t know if it was successful. If you read it, let me know what you think about it. The position paper “Reputation is in the eye of the beholder: on subjectivity and objectivity of trust statements” can be read after the jump (i.e. click on “more” if present).

Microsoft trying to use its patents wallet weapon again Free Software. Moglen: “Waterloo is here somewhere”

Interesting article by CNN: Microsoft takes on the free world. Microsoft claims that free software like Linux, which runs a big chunk of corporate America, violates 235 of its patents. It wants royalties from distributors and users. Users like you, maybe.

Some quotes and short comments below.

More than half the companies in the Fortune 500 are thought to be using the free operating system Linux in their data centers.

I didn’t know. Well, it is becoming harder and harder to dismiss Free Software, isn’t it? And in fact …

Microsoft asserts that one reason free software is of such high quality is that it violates more than 200 of Microsoft’s patents.

And this is ridicolous, Microsoft is claiming that GNU/Linux developers are studying the patents Microsoft got and copied them? Or it is more that Microsoft is patenting everything (instead of spending the money it gets from its monopolistic position for creating a decent Operating System) notwithstanding evident prior art? Trying to patent smileys? With the US Patent Office
even rejecting a patent previously granted to Microsoft for a file format as “obvious and therefore not subject to patent”? Well the examples could be thousands.

The conflict pits Microsoft and its dogged CEO, Steve Ballmer, against the “free world” – people who believe software is pure knowledge. The leader of that faction is Richard Matthew Stallman, a computer visionary with the look and the intransigence of an Old Testament prophet.

I loved the picture used by CNN

Furthermore, FOSS has powerful corporate patrons and allies. In 2005, six of them – IBM (Charts, Fortune 500), Sony, Philips, Novell, Red Hat (Charts) and NEC – set up the Open Invention Network to acquire a portfolio of patents that might pose problems for companies like Microsoft, which are known to pose a patent threat to Linux. So if Microsoft ever sued Linux distributor Red Hat for patent infringement, for instance, OIN might sue Microsoft in retaliation, trying to enjoin distribution of Windows. It’s a cold war, and what keeps the peace is the threat of mutually assured destruction: patent Armageddon – an unending series of suits and countersuits that would hobble the industry and its customers. “It’s a tinderbox,” Moglen says. “As the commercial confrontation between [free software] and software-that’s-a-product becomes more fierce, patent law’s going to be the terrain on which a big piece of the war’s going to be fought. Waterloo is here somewhere.”

I didn’t know about the OIN but the mention to cold war is really appropriate. And to the possible Armageddon as well. I’m a bit surprised that Microsoft decided to take it so frontal. If they lose this one, it will be one of the last. Obviously they have thought very well about the strategy. Uhm.

Anyway this is one more reason for not embracing software patents in Europe. Software patents don’t make sense but also politicians who seems not too interesting in what make sense but mainly in consensus should understand that letting Microsoft sue European companies and citizens is not a too clever move.

He says that the Linux kernel – the deepest layer of the free operating system, which interacts most directly with the computer hardware – violates 42 Microsoft patents. The Linux graphical user interfaces – essentially, the way design elements like menus and toolbars are set up – run afoul of another 65, he claims. The Open Office suite of programs, which is analogous to Microsoft Office, infringes 45 more. E-mail programs infringe 15, while other assorted FOSS programs allegedly transgress 68.

Since you are simply tossing numbers in the air, why not saying that every program violates at least 1.988.456.645.110.000 Microsoft patents, eh?

Stallman demanded that all contributors to GNU projects assign their copyrights to the Free Software Foundation, which Stallman set up and controlled. That meant that anyone who distributed free software covered by those copyrights had to abide by a license Stallman wrote, called the GNU General Public License (GPL).

I think this is the only technical error in the article. I think contributors to the GNU projects retain their copyright and simply decide to use the GNU GPL licence. Am I wrong?

(Stallman insists that “GNU/Linux” is the proper name, and he refuses to give interviews to reporters unless they promise to call it that in every reference. In part for that reason, he was not interviewed for this article.)

I love this man! ;-)

Smith was not to be deterred. Since the GPL covered only distributors of Linux, nothing stopped Smith from seeking royalties directly from end users – many of which are Fortune 500 companies. He would have to proceed carefully, however, because most of those users were also major Microsoft customers.

The terrain is slippery. I’m a bit surprised Microsoft took it so frontal. The article also speaks about Microsoft-Novell deal and this is quite important as well. Anyway we’ll see in the coming months where is the Waterloo. Stay tuned.

Update: Growlaw publishes some reasons for not worrying and they are clever and clearly explained.
