But nothing day

Buy Nothing Day Tomorrow, FRIDAY, NOVEMBER 26 2004 IS BUY NOTHING DAY.
“For 24 hours, millions of people around the world do not participate — in the doomsday economy, the marketing mind-games, and the frantic consumer-binge that’s become our culture. We pause. We make a small choice not to shop. We shrink our footprint and gain some calm. Together we say to Exxon, Nike, Coke and the rest: enough is enough. And we help build this movement to rethink our unsustainable course.”

And since it is almost time, I support the Buy nothing Christmas and the xmas resistance movement. If you know me, please buy nothing for me for Christmas but stop, relax and think. Thanks!

NeverForgetAttachment: Thunderbird extension needed

thunderbird_extension_snapshot002.pngHave you ever sent an email writing “in attachment you can find…” and then forgot to attach the file? Have you ever received such an email? I guess so. At least I had, many times. So, I’m invoking the LazyWeb and asking for an extension to the free software mail reader Thunderbird (link not working at the moment, use the cached version). A name for the extension can be NeverForgetAttachment but of course the creator will decide the name. How could the extension work? Version 0.1 will simply look for the words “attach” or “attachment” and, in case they are present and there is no attachment when the user clicks the send button, a small window such as the one you see in this post will popup and asks the user if she wants to attach a file. Following versions can even use some machine learning in order to learn which words (or combination of words) refer to an email with a desired attachment and which don’t and react consequently. This can especially be the case if the author don’t want to enter the relative “attach” word for every language in the world. Ok, I’m waiting for someone to create the extension, could this be you?

The Wired CD: Fight for your right to copy

The WIRED CD: Rip. Sample. Mash. Share.. First example of creative commons cd, I hope many will follow this bright example. You can listen to the songs streaming the related WebJay compilation (once there, just click on “play page”).
Songs are released under 2 creative commons licences:
Sampling Plus: Songs under this license allow noncommercial sharing and commercial sampling, but advertising uses are restricted.
Noncommercial Sampling Plus: Songs under this license allow noncommerical sharing and noncommercial sampling.

Buy Wired if you want the cd. The front cover says: “Fight for your right to copy”.
UPDATE: I started reading Wired and found this great article: We pledge allegiance to the penguin, and the intellectual property regime for which he stands. One nation, under Linux, with free music and open source software for all. Welcome to Brazil!. Every day I found one more reason to move to Brazil, when I’ll finish my PhD.

Search engine switch

While the evil company launches its search engine (no link – no pagerank), i finally decided to make the switch to Yahoo! search engine. If you use firefox (you should!), it is as easy as changing the icon in the top-right box (mycroft).
[This blog is 1st results if you search for Paolo, in Yahoo! but of course this is not the only reason I switched ;-) I like to promote some diversity in the search engine arena as well]

CiteULike: A free online service to organize your academic papers

[I’ll write something about my trip in Israel later on, as time permits]
I just found on HubLog an online service I was really waiting for: CiteULike (a prototype service to manage your personal library of academic papers). When you are logged in and visiting a page related to a paper, you can post that paper to your online library using a bookmarklet. In doing so, you can also specify tags, a list of keywords you’d like to associate with this article (a la and flickr) and optional notes. The service is very similar to (simple, tag-powered and social), but precisely tailored for academic papers. You can also see all the papers tagged under a certain tag (for example networks). Cool!

Travelling to Cyprus and Israel

I’m at Coopis 2004 right now (in Agia Napa, Cyprus) and next week I’ll move to Jerusalem in order to meet Zvi and other people of the Multiagent Systems Research Group of the Hebrew University of Jerusalem. I’ll be back in my office on November 9.
I was hoping to do a lot of work during the coopis conference but the wireless network is not working very well and so expect few or no blogging at all.
I almost forgot to say that I’m presenting “Trust-aware Collaborative Filtering for Recommender Systems” (find it under papers section). Check it out if you are interested in Recommender Systems and Trust.

Repository of category-tagged blog posts: anyone?

Some colleagues of mine are working on “how people can reach a shared common dictionary/language to denote concepts” (or at least understand each other still using their keywords). See Advertising games. We want to test ideas using real data from the blogosphere. The idea is to detect when 2 bloggers are posting about the same concept/topic but use different names to tag it (the post’s category). For example, I use “trust and reputation”, someone else uses “reputation” but we may speak about the same concept.
The questions:
– There is an aggregated repository of posts with categories?
– If not, Have you any idea about how can I collect this information?
– posts must have a category associated (livejournal and blogger don’t let do this, while MovableType and WordPress yes).
Some ongoing web search about the topic we’re doing can be found at this wiki page, and this too. Thanks for help!
