An old home

An old home

Sub-Evil Boy and I are off tomorrow early for a week+ trip to the wilds of Wisconsin. I don’t think I’ll have a lot of internet where we’re heading, so there probably won’t be much/any posting for a while. Also, since comments are moderated, they may not show up for several days. Sorry about that.

See you when I’m back!

Weather Girl has a friend in town, so we all went out to the local Wetlands Office this morning and hiked the trail they have there, braving ticks and skeeters throughout. This is a where some insect set up shop in the stem of a flower last year, creating this nice little home for its young ‘uns, some of who are presumably doing (or preparing to do) the same thing this summer.

Fine photographs; fine discussion

'North Carolina' by Elliott Erwitt

Magnum has an excellent retrospective of Elliott Erwitt’s work. The whole photoessay takes something like half an hour to go through, but is definitely worth the time. I’m not thrilled by all the photos they’ve chosen (some seem a bit too clever), but there are some wonderfully evocative, insightful images in the set, some (like this one) that are extremely powerful, and more than a few that are just hilarious. His voice over and stories are also very cool. Most certainly recommended.

Thanks to John Naughton for the original pointer.

'Critical Mass Ride' by Famewhore
It’s long been the case in the U.S. that companies could get tax breaks on money they spent assisting employees in driving cars to/from work (including the vehicle itself, fuel, parking, etc.). Some crazy hippies or eco-terrorists or some such have proposed the radical idea that similar tax breaks should also exist in support of people cycling to work. H.R. 1498 would (according to the League of American Cyclists):

provide bicyclists with a similar tax benefit to that currently enjoyed by transit users and car parkers, through voluntary, employer-run programs. This small incentive to ride rather than drive to and from work should be seen as an important element of broader efforts to tackle climate change as well as traffic congestion, obesity and other critical challenges.

That clearly sounds like a terrible idea - it’s obviously my Great American Right to be fat, lazy, and drive a big-ass SUV whenever humanly possible, and lord knows the tax code should encourage such behavior whenever and however possible.

Wacko loonies who would actually wish to support such nonsense, however, can read the text of the bill or even contact your congress critters and publicly express your silly ideas.

I did, and it was fun!

Here’s hoping they have second thoughts

Ted Stevens International Airport

This was one of the first things we saw when we flew to Alaska last July, and I must say that it was sad and depressing to see their airport named after Ted “Internet = tubes but not trucks” Stevens. Unfortunately clear and public demonstrations of gross ignorance of material central to a committee that he chairs didn’t really change anything; incompetence has rarely done much damage to a politician,

Now, however, we have all sorts of exciting scandal brewing (here, there, and elsewhere), and it’s fairly clear that his nearly 40 year run in the U.S. Senate has included more than a little shuffling of the cards under the table. Maybe this will be enough to cause the fine folk of Alaska have second thoughts about their airport naming strategy (if not their voting strategy).

Now how do we get Ray-gun’s name off that much more significant airport in D.C.?

And maybe librarians can start pasting ads in books?

Posted in Computing, Web development on June 25th, 2007

Christina's Strip Mall by t-squared

TechCrunch shares the disturbing news that some bright bulb has developed software that allows ISPs to insert ads into web pages as they pass through the ISPs servers. The user is then unable to tell the difference between ads that are “supposed” to be there (and presumably benefit the creator of the content they’re perusing) and ads inserted by their ISP without the knowledge or consent of the author(s) of the web pages in question. Quoting TechCrunch:

As a content creator I’m horrified that any page I create could be plastered with advertisements I don’t approve of as I’m sure many others will be as well. There are probably copyright issues as well in terms of hijacking original works for profit. We can only hope that this evil form of advertising does not spread beyond Texas.

This blog, for example, is free of ads so far, and is likely to remain so for the foreseeable future. We simply don’t get enough traffic to warrant such things. You, however, might be seeing it with ads that I know nothing about, which put no money in my pocket, and without you being aware that I didn’t put them there.

Ugly as this is, the extreme case is truly horrifying. Potentially every server that passes along your HTML packets could be inserting ads and otherwise altering or rearranging content. We could reach a point where the page viewed bears almost no resemblance to the page served, totally undermining any and all efforts to introduce some reasonable design principles to this intarweb thing. (Not to mention all the privacy and censorship issues that would naturally arise.)

As useful as I find blogs like TechCrunch and Pharyngula, for example, both are already horribly blighted by oceans of ads, many of which blink, move, wiggle, and jump in ways that make me want to beat someone publicly. And those ads are placed there by the people that run (or at least manage) those sites, who have a vested interest in not making their web pages so awful people just won’t go there. ISPs will have no such compunction because they’ll pollute everything equally, so their only real risk is annoying their users so much that they switch ISPs (not always an easy option) or simply stop going on-line (which would take a lot of annoying).

I suspect, however, that encryption could do a lot to solve this problem. I haven’t thought through the details, but I suspect that encrypting all web pages using something like https would make it impossible for ISPs to insert their ads because they’d no longer have access to the raw HTML. It would cause an increase in the amount of traffic on-line (encrypted information is almost always larger than its raw, unencrypted form), but I suspect this would be nothing compared to all the traffic generated by YouTube. And I’m betting nearly everyone would gladly wait a tiny fraction of a second longer for their page to download and decrypt if it kept it free of all this ISP spam. What would be nasty is if encryption schemes ran contrary to the powerful monitoring urges of governments; it would really suck to drown in spam just so Big Brother can keep an eye on what crazy music I’m listening to on-line.

Evolving buildable Lego structures

Posted in Computing, Research, Science on June 24th, 2007

Animated GIF of evolving bridge

More cool work out of Jordan Pollack’s lab at Brandeis. They’ve build a nice force simulator and design system for Legos called EvoCAD that lets you evolve Lego structures that satisfy various conditions. Pablo Funes, who recently finished his PhD, used this to evolve spans of over 2 meters, tree-like structures, and counter-balanced cranes (cool video of it lifting 1/2 kg).

Evolved Lego bridge

As pointed out by Think Artificial in their discussion of this work

…genetic algorithms result in … naturally messy constructs. This is actually one of the reasons that genetic algorithms are popular within artificial creativity research. Evolution results in various “unanticipatedâ€? or “surprisingâ€? constructs which can be perceived as creative.

Evolution, whether biological or “artificial” like that reported here, is an inherently messy business. It’s always forced to work with what it has, and is further hampered by the lack of any long-term plan or design. An incredibly powerful process, but unquestionably messy.

Thanks to Genetic Argonaut for the initial pointer.

But what about “Moon Unit”?

2007 Byte Bash - 41
WeatherGirl tipped me to an Observer article entitled “Names really do make a difference“, and I keep wavering between “Oh, surely not!” and “Well, duh, that was pretty obvious”. Apparently giving a girl a “girlie” name significantly reduces her likelihood of studying math and science:

Both subjects [math and physics], which are traditionally seen as predominantly male, are far more popular among girls with names such as Abigail, Lauren and Ashley, which have been judged as less feminine in a linguistic test. The effect is so strong that parents can set twin daughters off on completely different career paths simply by calling them Isabella and Alex, names at either end of the spectrum. A study of 1,000 pairs of sisters in the US found that Alex was twice as likely as her twin to take maths or science at a higher level.

The (highly speculative) causalities are the reasonably obvious ones: Seeing names like “Barbie” or “Breeze” on the class list or application form brings beaucoup baggage to the party. This is hardly a win, especially since the patriarchy already ensures that females already have plenty of baggage when it comes to science and math. It’s also telling, if not entirely shocking, that giving boys certain names can have similar effects. Seeing “Bubba” on the football roster might elicit a snicker, but likely no surprise; seeing “Bubba” at the math league finals, on the other hand…

So it would seem that some parents have a fair bit to answer for:

‘A name is part of an impression package,’ said Mehrabian. ‘Parents who make up bizarre names for their children are ignorant, arrogant or just foolish.’

In the case of the Zappa family, I’m voting for “arrogant”; Frank certainly wasn’t ignorant.
