Rat brain art

Wednesday, July 9th, 2003

botart.pngResearcher 1: Hey, let’s make a robot that learns how to make artistic pictures over time.

Researcher 2: That’s an interesting idea, but it’s been done.

Researcher 1: OK, so we’ll use a collection of disembodied rat brains!

Researcher 2: Again, nice idea, but rat-brained robots are passe.

Researcher 1: OK, OK. How about having a drawing robot in Australia controlled by a bunch of cross-wired robotic rat brains in America.

Researcher 2: Hey… sounds like you’ve got something there.

Gladiator, the robot

Wednesday, July 9th, 2003

The Marine Corps are testing a multi-purpose tele-operated robot called the the Gladiator, a remotely piloted “mini tank-treaded terror bristling with so many cannon and guns that only a Hollywood screenwriter could have dreamed it up.” And how would it be employed?

The Camp Smith demonstration of the Gladiator was based on a scenario in which an angry mob of 600 activists in a desert city refuses to disperse.

Ah yes, but what will they do when the angry mob is of 600 robot activists? (via Gizmodo.)

Some butterflies

Cleaning off the hard drive, I ran across some photos I took of butterflies last month at the San Diego Wild Animal Park

   

Getting rid of advisees

Tuesday, July 8th, 2003

Perhaps “getting rid of” is the wrong way to say it :). Kara Kerwin has just accepted a position as Asst. Director of Electronic Media at Hamilton College. Way to go Kara! We still need to get her done with her thesis, but given the market right now, it’s great that she found such a nice match to her interests.

Cliff (Chunta) Peng defends his thesis, on factors motivating participation (and lurking) in online discussions, tomorrow morning.

Since all of my other advisees have either dropped out of the program or switched to someone else (I’m sure it’s my winning personality), that leaves me with only one advisee in the fall, Jia Lin, who will be moving out to the left coast in August and will be completing her dissertation (blog-related) out there.

Hopefully there will be some good prospects in the new class. If not, maybe if I am quiet enough no one will notice that I have no (local) advisees when the temporary assignments go ’round…

Of hammocks and schools

Monday, July 7th, 2003

Been doing some soul searching, rebuilding my Personal Mission Statement, and why? I know just where I want to work:

His next project is to develop a school in Sao Paulo based on the principles of freedom and flexibility. “The schooling system seems very stupid, much as the business world is,” he says. “As with cars and airlines it needs someone from outside the business to rethink it from scratch. For instance, why do schoolchildren need a two-month summer holiday? That’s a hangover from agrarian societies when farm children were needed for harvesting. Why are children in London still taking that amount of time off?”

This guy understands how offices are supposed to work; I’ll be interested to see where he goes with the school.

Techie Class Texts

Monday, July 7th, 2003

I had hoped to do a techie programming class for informaticians this fall. As it turns out, I probably will not. Instead, I’m going to do a broader “Internet Research” seminar at the grad level. Nonetheless, I hope I’ll get a chance to teach the techier class at some point; maybe next year.

I had settled on How to Think Like a Computer Scientist (Green Tea Press, $25). I’m currently reviewing Text Processing in Python (Addison Wesley, $35), after reading a positive review (along with some interesting comments) over at Slashdot.

This is really putting the cart before the horse, but assigning these books raises some interesting questions. Both are cheap when compared with either the average textbook or the average tech book. On the other hand, both are available free online. The latter has been made available in text files at the author’s own site, the former is under the GNU license and can also be found online.

The question of whether I should buy the hard or soft copy is one I already wrestled with when Cory Doctorow published his Down and Out in the Magic Kingdom. I read the book and enjoyed it, but I did not necessarily enjoy it $25 worth (or even $17 worth). I thought it was worth about a matinee movie these days: somewhere in the $5-$10 range. I wrote Cory to tell him this. In retrospect, such a letter (I like your book at about 1/5 of retail) was probably mildly insulting. On the other hand, the default–since I had already read the book, was not to pay at all, to be a free rider. His suggestion was that I buy the book and donate it to a library. It’s a good solution, but given what I already spend on books, and that I have been technically bankrupted by my educational experience, I simply don’t have that much to spend on books right now. Lest the reader think that this tight-fistedness is only because I’ve already read the book for free, I have held off on reading two books–After the Quake and Pattern Recognition–until I could get reasonable copies second hand.

I’ve offered to two people–one whom I know in RL and one whom I only know virtually–that I pay $5 of their purchase price if they buy the book. Cory probably sees less than a dollar for every book sold, but this provides some encouragement for Tor to continue to support authors, books, and publishing like this. (I have a feeling that Tor is already encouraged by sales of the book, but they might not be sure whether there is a direct connection to it being released online. Moreover, they might reasonably think that while this is a novelty at this stage it may not be a sustainable way of promoting books.) All this angst over a book I read on my PDA while working out.

When it comes time to assign readings for a class, this is further magnified. Last spring, I assigned a book for my media law class that cost $80. I know the author, but I don’t think that colored my decision; it’s a very good textbook. But it was not easy for me to assign such an expensive book to the students. As a grad student, I was the first one to seek out library copies (often across town) and other ways of keeping my book bill down. I hate creating new costs for students. It seems to me unbalanced that the textbook market is far more profitable than the fiction trade.

The solution in this case seems simple enough. I order the books through the bookstore, and I tell students that there is a hard copy available as well as readings online. I know in such cases that some proportion–usually a minority–of the class will buy the text and this will help authors get rich (i.e., be able to buy canned tuna). It’s just not a very satisfactory solution. What I want is simple: I want to be able to send Cory $5 for the book. I suppose I could just send him a random check, and let him tear it up if he wants to, but that doesn’t seem right either.

At least in the form I have now, neither of my fall classes have assigned books. In the case of the theory class, this means a set of readings that they will have to track down and photocopy or print (since creating a “reader,” once cleared for royalties, would mean about $200 per student). I know they would prefer a textbook, and I recommend a few, but I don’t assign any.

The best solution might be to have students write their own textbooks. In an undergraduate class, I assigned students to write textbook chapters, and about 3 of the 20 were better than those found in most com theory textbooks. One of these (on “muted group” theories) was somewhere out on the net at one point as a pdf, but I cannot find it now. I know I have a copy of it, and asked the students at the time for permission to post it, so I will keep an eye out. This fall, I will recommend that students upload their area papers to Wikipedia. That may push us a bit in the right direction.

Fighting criticism

Bush Asks Congress For $30 Billion To Help Fight War On Criticism

WASHINGTON, DC—Citing the need to safeguard “America’s most vital institutions and politicians” against potentially devastating attacks, President Bush asked Congress to sign off Monday on a $30 billion funding package to help fight the ongoing War On Criticism.
