Festival of Economics (May 29 – June 2, 2008) in Trento

The program is very interesting! One more chance to plan some days to visit Trento!
The topic of the third edition (from 29 May to 2 June) is “Market and Democracy”. Check the program.

From festivaleconomia.it:
Paul Krugman, Lecturer in Economics and International Relations at the University of Princeton and the London School of Economics, leader writer for the “New York Times”, will reflect on how ideologies can condition the functioning of the markets; Paul Collier, Professor of Economics at the University of Oxford, will explain to us why African countries with a low income are failing to jump on the development bandwagon; Benjamin Friedman, Lecturer in Political Economics at the University of Harvard, will challenge the long tradition of thinking which suggests that economic wellbeing leads to serious moral consequences: from individualism to exploitation of the work of others and the disintegration of traditional social bonds; Luisa Diogo, currently Prime Minister of Mozambique, will illustrate her experience of government, whose efficacy has excited the interest of observers from all over the world; Egor Gaidar, Prime Minister of Russia in 1992 under Boris Yeltsin’s government and one of the first to lead Russia towards the free market, will explain the difficulties in the passage from the Soviet to the capitalist system; John Lloyd, journalist and leader writer for the “Financial Times”, will analyse the information scenario, in the face of a growing concentration of ownership of newspapers and television stations, both in Europe and in the USA.
These and many others will be joined by important figures in the Italian public debate, including among others Mario Monti, Guido Rossi, Francesco Giavazzi, Luciano Gallino, Sergio Marchionne and Piercamillo Davigo.

Science2.0 and the Scientific Bzaar: collective brainstorming for better research

Saturday I participated in Sci(Bzaar)Net, an event organized by Gianandrea Giacoma (thanks Gian!) for discussing about how we can (in Italy) make use of the Internet for a better spreading, production and management of scientific knowledge.

There were around 40 people and 15 presentations of 10 minutes each plus 10 minutes discussion and, at the end, the global brainstorming.

My presentation was titled “Science2.0 or How happy is a researcher discovering the existence of Yet Another Social Network for Science?” and I was playing the devil’s advocate on why researchers didn’t embrace in mass Web2.0 tools for their daily activity. Actually I understood I had to speak for 20 minutes so I prepared the slides accordingly but then I was told it was only 10 minutes so I had to run a lot (speaking at double pace!), the alternative could have been just to present one slide every two but I choose the “speak very very fast” strategy. You can find my presentation on slideshare or embedded here below, I would be very happy to receive feedback! It is released under CC-BY-SA so feel free to reuse it.

I got many interesting points which I try to briefly summarize in the following. But first photos from Flickr tagged as sci(bzaar)net and slides from Slideshare tagged as sci(bzaar)net.

One thing I noticed is that there were no professors and, since we like to think big, no University rectors! So I launch a contest: the first one who convinces a rector of an Italian University to open a blog gets a weekend in Trento, hosted by me, everything included! Can you handle that? Come on, go and find the blogging rector!

I didn’t follow too much the first presentations because I was finishing mine (my bad!). The first one I was able to follow was by Federico Bo and it was a very interesting survey about how Italian universities are using Web2.0 tools: touchscreens, webtv, blog aggregators, second life, e-catalunya, moodle, podcasting, social bookmarking, … Check the presentation by Federico.

Another interesting presentation was by Paolo Guglielmoni: “Culture as a virus” claiming that viral marketing and culture are not enemies, they never were in history and they are not now. He cited Booktrailers as a creative example of this. Still, how can I make my research into a viral meme is not an easy question.
The most amazing presentation was by Folletto who is a master in making visually impressive and semantically profound presentations, this one was titled “Paralipomeni dell’Oggettivazione Sociale” (Paralipomeni of Social Objectivism) and you can see it on slideshare.

It was great to meet again Bonaria, who is becoming an expert on library2.0 and Matteo Brunati who is trying to import the innocentive model in Italy with fullout and to meet a lot of interesting people I didn’t know yet. I also met David Orban, of openspime fame, which I managed to invite for a talk in Trento, probably on June 6th.

The final brainstorming was very interesting as well. Overall I think that, at least in Italy, for changing how researchers approach Web2.0 tools some push from the top is needed. It is not enough to have a push from the bottom (normal people like me and the other ones who met in Milan for sci.bzaar.net). Of course from the bottom we can try to show the light to people on top. For example I think the European Union now asks that every funded project must have a public Web page with its own domain, possibly a blog and surely a repository of produced documents and reports. It also somehow encourages to release the software as Free Software. This is a push from the top which, I think, is going to have a much higher impact than anything the sci.bzaarers can never achieve from the bottom.

Idea I see in my notes that I need to write down somewhere: write something about “the long tail of trust”.

Last thing I want to mention is the use of a human counter for signaling the passing by of time. On the back of the room, just in front of the speaker it was projected a previously recorded very big image of one of the guy (forgot the name!) Dario Violi with a red ball on top of it for every minute already passed. When the time limit was approaching, the face was becoming more and more sclerotic and when the 10 minutes were over, it was going totally mad and it was impossible for the speaker to keep speaking, it was too funny and disturbing. A very clever way to keep speaker in their time slot! I need to use it if/when I organize a conference!

Thanks to Flickr I also discovered that I move a lot the hands while speaking ;)

And thanks again Gian for organizing a great event!

Setting expiry time to infinite by default in Mediawiki

If you follow a mediawiki powered wiki and have to block users who spam the wiki, this trick might save you precious seconds. When you go to http://www.example.com/wiki/Special:Blockip/xxx.xxx.xxx.xxx you get a form in which the expiry field is set to “other” by default, then you have to change into “infinite” (if this is what you like) and then to click “Block this user”.
It would save seconds to have the expiry field already set by default to “infinite”, but how we do it? The way I found is the following. Edit the file includes/SpecialBlockip.php and around line 101 insert $this->BlockExpiry = "infinite";. There could be a variable you can set in the config but I haven’t found it.
If you didn’t understand what I was writing, this is good! This means you don’t have to unspam a wiki! ;-)

Claerbout’s Principle at Free Software Conference

This weekend Trento hosted the Italian Free Software Conference
. I could attend only friday because then I went to Milano for sci.bzaar.net (report in next post).
There was a very interesting presentation by Emanuele Somma about Bank of Italy and their internal use and infiltration of Free Software.
He cited the paper “Reproducible Econometric Research (A Critical Review of the State of the Art)” in which the authors, Roger Koenker, Achim Zeileis, cite Buckheit and Donoho (2005) citing what de Leeuw (2001) has called Claerbout’s Principle:

An article about computational science in a scientific publication is not the scholarship itself, it is merely advertising of the scholarship. The actual scholarship is the complete software development environment and the complete set of instructions which generated the figures.

Koenker and Zeileis go on reporting about scholars in economics have somehow turned into programmers:

The transition of econometrics from a handicraft industry (Wilson, 1973, Goldberger, 2004) to the modern sweatshop of globally interconnected computers has been a boon to productivity and innovation, but sometimes seems to be a curse. Who among us expected to be in the “software development” business? And yet many of us find ourselves precisely in this position, and those who are not, probably should be. As we will argue below, software development is no longer something that should be left to specialized commercial developers, but instead should be an integral part of the artisanal research process. Effective communication of research depends crucially on documentation and distribution of related software and data.

So their contribution:

Our main contention is that recent software developments, notably in the open-source community, make it much easier to achieve and distribute reproducible
research.

Free course about GNU Linux in Trento

I helped Engineering With Borders to organized the course “Linux per tutti, tutti per GNU/Linux” (“Linux for all, and all for GNU/Linux”) (see page on TrentoWiki).
The available places were 25 (we were reserving place for students of non-scientific faculties) but we receive more requests so there will probably be another course in October.
Today there is first meeting which is open to everyone: at 18:30 Alberto Gistri of Golem Empoli will speak about “Software Libero” – Conoscere il Software Libero e le sue potenzialita’ sociali, culturali, economiche e tecniche.”.
Join in!

Italian Free Software Conference this weekend in Trento

Trento, 16-17-18 May 2008.
Check the program (in Italian) at confsl.org.
There will be an Invited talk by David Hakken of Indiana University “Free Software as Virtual Organization”, other very interesting talks and many local experiences by enterprises, school and public administration. And there will also be an OpenStreetMap mapping party in Trento.
I can only attend on Friday because on Saturday I’ll be in Milan for Sci.bzaar.net. See you there in one of the two occasions!

Sci(entific) B(a)zaar Net(work): sci.bzaar.net, May 17, 2008 in Milan

Sci Bzaar logoNext Saturday (May 17th, 2008) I’ll be in Milan at the Politechnic School of Design for sci.bzaar.net.
With some friends of bzaar.net and few people I still don’t know, we will brainstorm and discuss about how Web2.0 dynamics can be adapted and imported into science. A sort of hybrid between a BarCamp, a traditional event and a Pecha Kucha, about science and research. Sweet!
The title of my talk will be “How much is a researcher happy discovering the existence of Yet Another Social Network for Science?”.

Report of Conference on Business Information 2008

Business Information Systems conference logoI spent the beginning of the past week in Innsbruck for the 11th International Conference on Business Information Systems.
My presentation went well but I’ll post about it later. Overall the conference was interesting and worth the trip.
Many talks were mentioning Semantic Web. What extremely positively surprised me was that the approach to Semantic Web was very very pragmatic in all the presentations, a sort of Pragmatic Web or, as I prefer, a lowercase semantic web.
The peaks of the conference were a great keynote speech by Fabio Ciravegna titled “Challenges and Methodologies for Acquiring and Sharing Knowledge in Large Distributed Environments”. He presented the approach of his group at the University of Sheffield on knowledge capture, which is very very pragmatic and just makes sense. Among others, he reported how noting that what workers in a big company (Rolls-Royce) were doing was creating word and excel forms and passing them around via email, they decided to provide a simple web interface for creating forms. This simple change allowed a lot of interesting services on top of it, services which use semantics when it adds value and not for the sake of it. I cannot resume his very interesting many points here but you might want to check his slides (from a different presentation) at around page 71 or just his Web page with a list of the many projects in which semantics is used in a pragmatic and reasonable and adding value way.
Another peak was a great tutorial by Emanuele Dalla Valle titled “RSWA 2008 – Realizing a Semantic Web Application”. He explained how to develop step-by-step a Semantic Web application that expects a music style as an input; retrieves data from online music archives and event databases; merges them and let the users explore events related to artists that practice the required style. He challenged the Semantic Web technologies on the Web 2.0 ground of realizing a mash-up that reuses, transforms and combines existing data taken from the open Web (namely MusicBrainz, MusicMoz and EVDB). Again a clever use of semantics when semantics can add some value and a clear explanation.
I suggested him to record this tutorial next time and put the video somewhere on the Web because it is really a great example (the first I’ve seen) in which Semantic Web really add value over more simple way of developing applications (Web2.0). For now you can just check his slides (released under a Creative Commons license). And also check the Semantic Web Activities group at Cefriel which has many interesting projects and ideas.
And there were few other peaks: Couchsurfing is always a great experience which never ceases to amaze me. We were 6 people (Khrista and Sarah, 2 canadian girls, Bruno, a dutch guy which is spending one year traveling around Europe , see useuropeans.com, myself, and Manuel and Yvonne, our 2 lovely hosts) sleeping in a small house with mattresses everywhere.
And I started twittering thanks to the push by Andre’ Passant at the conference, who also helped me to make my foaf file to remain always up to date by automatically including the results of export of facebook, flickr and other web2.0 services. However for now the foafing didn’t really work out though.
And I also started geocaching thanks to jailway: after the conference dinner we found my first cache near the Golden Roof.
