Pink Floyd

Pink Floyd with Syd Barrett performing Astronomy Domine live at Beat Club and an interview with Syd Barrett and Roger Waters. The pretentious host of the show, Hans Keller, chastises the band for their "continuous repetition", "terribly loud" volume, and their "proportionately a bit boring" sound.

O meu mantra diário anti-depressivo ^_^


Miguel Esteves Cardoso de volta no MetaFilter

Após uns dois anos de ausência, o senhor Miguel Esteves Cardoso voltou ao MeFi :)

Aqui fica a lista de posts dele nesta comunidade online, da qual é membro desde finais de 2001, e ainda uma lista de threads de sua autoria no MetaTalk, o fórum de discussão que se encontra associado ao MeFi.

Apesar de ter atravessado um período menos interessante, o MeFi tem nos últimos tempos voltado a captar a minha atenção. Aproveito ainda para fazer referência a um dos meus últimos vícios na Web, o fórum "Die Puny Humans" que substitui o antigo site do escritor de comics depravado Warren Ellis (autor da série Transmetropolitan).

A/B Test Design for IR Systems

After cleaning my desk today, I found some tutorial notes from a talk given some years ago by Jan Pedersen and Knuth Magne Risvik from Yahoo! Inc. The tutorial covered only the basics of Web Search, but in it I found a very interesting idea for doing IR evaluation using real search engine users. Coincidently enough, I've been recently discussing similar ideas with Michael Stack from the Internet Archive, and I'm so excited with this that I think I'm actually going to try making a small testing prototype that implements this (I'm guessing that a few lines of JavaScript/HTML, using IFRAMES and the prototype/ libraries should be enough). Here's the general evaluation methodology, simply called A/B surveys:

Strategy : Compare two IR systems (e.g. systems using different ranking formulas, two clustering systems using different algorithms or anything else you can think of) by asking panelists to compare pairs of search results and assign scores.

Queries : Users can select from a list of possible queries. The study can, for instance, reuse queries from WebCLEF of (Web/HARD)TREC.

URLs : The interface can shown the first page of results for both systems being compared.

Voting : Users can assign votes using a 5 point (or 3 point, don't know which one is better) scale. Each user ideally rates 6 different queries, one being a control query containing random URLs. The system should reject voters who take less than 10 seconds to vote.

As oposed to more traditional ways of involving users in IR evaluation, this approach can actually produce interesting quantitative results (e.g. besides testing if one system outvotes the other, we can also check for the difference being statistically significant), and it also has the advantage that since humans are involved, visual relevance plays its role in evaluation.

I also hope this methodology can be usefull in evaluating search result clustering, which is much more difficult that evaluating ad-hoc search.

Free MP3 repositories on the Web

These MP3 repositories are so interesting that they deserve a separate blog entry, instead of just appearing on my link feed ^_^

The first one comes from the Free Information Society Web site. It does not offer music files, but historical speeches by the likes of Fidel Castro, Che Guevara or Einstein. Here are a few examples:

Winston Churchill - Finest Hour
Albert Einstein - E=mc^2
Bill Gates - Vision
A Che Guevara Speech

The second is the Piano Society, offering Free Quality Recordings of Classical Piano Masterpieces. Here are a few examples of what can be found on the site:

Bela Bartók - Allegro Barbaro
Maurice Ravel - Pavane de la Belle au Bois Dormant
Claude Debussy - Arabesque no.1

Finally, the Classic Cat Web site offers a directory with links to over 2800 free to download classical performances on the internet, sorted by composer and work. This site links to several others with the actual mp3 files, among them the Piano Society.


It's a Virus

A little song by sci-fi writter David Brin.


Back in the Pleistocene,
When we were still marine,
a virus launched a quest,
to be the perfect guest
And re-arranged our genes.

So to this very day,
Whether you grok or pray
all your inheritors
count on those visitors
And what they make you pay.


It’s a virus,
It inspired us,
to rise above the mud.
It’s a virus,
It’s desirous,
of your very flesh and blood.

Now I know your body’s burning,
But don’t give up the ghost.
Tiny viruses are turning you
Into the perfect... host.

Though you may curse microbes
who make you blow your nose,
evolution bends
to what a virus sends,
making us recompose.

Though when you least expect
You may be struck down next
thank the virus, he
put us in misery,
But then he gave us sex!

It’s a virus,
Its inspired us,
to rise above the mud.
It’s a virus,
It’s desirous,
of your very flesh and blood.

Now I know your body’s burning,
But don’t give up the ghost.
Tiny viruses are turning you
Into the perfect... host.
