Professor: What is an encyclopedia? Student: Is it something like Wikipedia?

I was viewing the presentation by Steven Walling titled “Why Wikipedians are the Weirdest People on the Internet” (embedded below) and the second slide was a twit by alisonclement which says:

Yesterday I asked one of my students if she knew what an encyclopedia is,
and she said, Is it something like Wikipedia?

Amazing! Changing times indeed, I remember when I was a kid and one of the most valuable things in our house was a 20-something volumes encyclopedia, admiringly and respectfully placed at the center of our best cupboard … ;)

Larry Wall talk in Povo

On February 17, 2011 at 11:00, Larry Wall, creator of the Perl programming language, will give a talk in Povo (where I work), organized by CoSBI (The Microsoft Research – University of Trento Centre for Computational and Systems Biology).
The title is “That Goes Without Saying (or Does It)” and the abstract is:
Linguist Roman Jakobson famously said, ‘Languages differ essentially in what they must convey and not in what they may convey’ Contrary to the Whorf-Sapir hypothesis, your language of choice does not generally prevent you from thinking certain thoughts, but your language can certainly make it easier or harder to express those thoughts. Lately I’ve enjoyed playing with various Perl examples on rosettacode.org, and have noticed this principle in action. In this talk we’ll look at some of the ways a language can make your life more miserable than it needs to be.
The seminar is free of charge but for logistics reasons you need to confirm your attendance on CoSBI site.

Beautiful visualization of Wikipedia discussions on article deletions


straight AfD sample

s-shaped AfD sample


spiral-like AfD sample

At notabilia.net, Dario Taraborelli, Giovanni Luca Ciampaglia and Moritz Stefaner put together a neat visualization of the 100 longest Article for Deletion (AfD) discussions. Each time a user joins an AfD discussion and recommends to keep, merge, or redirect the article a green segment leaning towards the left is added. Each time a user recommends to delete the article a red segment leaning towards the right is added.
