You have no idea how efficient your muscles are at turning Cheerios into chin-ups. Muscles are silent, smooth, and powerful. All useful machinery humans have built to date are clacking whirring rotating things. IEEE Spectrum has a good article this month (not available for public reading, unfortunately) about artificial muscles. This same topic was recently a cover story in Scientific American (PDF version here). I’m very happy to see interest in this topic taking off, because I’m convinced it’s one of the great enabling technologies of our age if we can make it practical. The author of the Spectrum article, Yoseph Bar-Cohen, has an Artificial Muscle web hub that details a grand challenge for the young field: an armwrestling match between a robotic arm and a human. It looks like this is actually going to happen in March of next year. Let’s hear it for Team Cyborg!
Fear and loathing in suburbia
I gave a talk this morning about the MATLAB Profiler at the Applied Behavioral Analysis Convention (see the listing here). In order to explain how profiling code works, I wanted one of those Family Circus cartoons where little Jeffy goes wandering all over the neighborhood. I thought I’d find them all over the net, but I only found one. I guess the Family Circus lawyers have been doing their work. For the purposes of my talk, though, this was just fine.
The Family Circus is as lame a comic as you are likely to ever run across. Even so, I was surprised by the depth of the hatred that exists for it out there. In my search for the “real” images of cute li’l Jeffy and Billy, I came across dozens and dozens of anti-Family Circus sites. After a while, I started to have more respect for FC creator Bil Keane. He clearly knows exactly how to poke a sharp stainless steel dental tool into the receding gumlines of Goth punks all across the country. To inspire that kind of loathing is no small achievement. Go Bil!
Anyway, my favorite anti-FC site was over at the Progressive Boink. This is the kind of critique I enjoy. Instead of saying Family Circus = LAME, he really deconstructs it. For instance:
In the comic presented here, Billy explains that he is “mousebreaking” Jeffy. Perhaps Billy meant to say “housebreaking,” because “mousebreaking” is not a word. But even if he did spell “housebreaking” right, it doesn’t make any sense, because Billy is teaching Jeffy to use a mouse, not a toilet.
The great thing about pop culture is that if you love it, then you love it, and if you hate it, then you can sit around and talk about why the hell so many people love it. Either way is a win.
The U.S. Navy in WWII
The amount of activity undertaken by the U.S. military in World War II is truly staggering to contemplate. Germany had to fight on both eastern and western fronts, but America fought on eastern and western fronts each separated by thousands of miles of ocean from the homeland. This meant mastery of the seas was imperative. Morison managed to talk President Roosevelt into giving him, as a working historian, a naval officer’s commission and assignment to various warships throughout the conflict. His book does a thorough job sketching out the scope and drama of U.S. naval operations in the war, and since he was literally on the scene at the time, he adds a welcome journalistic touch from time to time. For instance, he tells us that nobody in the service called Admiral William Halsey “Bull” Halsey. It was just Bill. Now you know.
Look at all them shopping carts!
Very simple and nicely designed, 300 Images From 1800 Sites has a clip-art-ish collection of icons gathered from sites all over the web. The juxtaposition of, say, 87 shopping carts makes a lovely little magpie shell collection… so many designers struggling to be original in a tiny 16-by-16 pixel space! You can almost hear the conversations: “Can you punch up that tiny mail envelope icon so it looks a little more edgy, so it’s all floaty and fast with a little dangerous-looking zing to it? Like this would be the envelope your parents wouldn’t let you date, you know, but not in a scary way? Could you do that by tomorrow? Thanks!”
Question: can you spot the ugly Amazon shopping cart?
When geeks become fathers
The Trixie Update is an obsessive baby blog about a little nine month old named Trixie. They (it seems to be mostly the dad who’s doing all the posting) record all kinds of data, things you might wonder about as a parent, but when on earth would you bother to collect the data? For instance: how long will one thousand diapers last? Answer: three and a half months. The sleep log is particularly interesting. They know total amount of milk consumed yesterday (32.7 ounces), and the number of minutes since last diaper change. It just goes on and on! The spectacle of Milk Week alone is worth the price of admission.
Ben MacNeill, the man behind the site, is even releasing software so that you too can obsessively track your baby’s every poop and pee: the Trixie Tracker.
If he can do this much with an infant child, he must have moved worlds before he had a kid.
Alchemy 101
One of the better books on alchemy. It contains one of my favorite quotes of all time. The eighteenth century Dutch chemist Boerhaave, who on being asked his opinion of alchemy replied:
Wherever I understand the alchemists, I find they describe the truth in the most simple and naked terms, without deceiving us, or being deceived themselves. When therefore I come to places, where I do not comprehend the meaning; why should I charge them with falsehood, who have shown themselves so much better skill’d in the art than myself? I therefore rather lay the blame on my own ignorance than on their vanity. Thus much I have long ago had a mind to say, concerning the knowledge of the true alchemists in physics; lest such skilful artists should be condemn’d by incompetent judges…. Credulity is hurtful, so is incredulity: the business therefore of a wise man is to try all things, hold fast what is approv’d, never limit the power of God, nor assign bounds to nature.
The ESP game
Suppose it was your job to label pictures with descriptive tags. You’d type in things like PICNIC, LIGHTNING for a picture. Then it would be easy for someone who needs pictures of a stormy picnic to find what they needed. Labeling pictures is very hard to automate, but very useful. So suppose it was your job to label 1000 pictures. Or 100,000 pictures. Or perhaps even 3 million pictures. What would you do?
Some clever people at Carnegie Mellon have come up with a perfect Tom Sawyer hack: turn labeling pictures into a fun game, and people all over the web will spend their spare time doing it. Apparently it’s working like a charm, because they claim to have labeled more than 3 million pictures using the ESP Game. You get paired up with another person, and the object is for you to agree on a label in the shortest amount of time. In the meantime, you generate labels furiously that all get logged into a database for later consumption. Brilliant. (Thanks, Jenifer!)
MTAmazon-based book list
I asked Kristin how her cool “what I’m reading now” display works. The magic behind the scenes is based on two nifty adaptations of Amazon’s generous web services: MTAmazon and BookQueue. MTAmazon makes it easy (via special tags) to provide information about any book that Amazon sells. BookQueue, when used in conjunction with MTAmazon, helps you manage lists of books. As an ensemble, it’s a beautiful illustration of how heterogeneous tools with clean APIs can work together in an open environment.
Thus inspired, I created a new book blog, Star Chamber Books. I’ve tried over the last year or two to build some useful tools for managing lists of books, but none of them worked very well. Too much work. I love books, and I enjoy managing lists of books that show what I’ve read and what I’m going to read. But even so, I was getting tired of writing special code myself. This way the special code problem belongs to somebody else.
Alchemy and porcelain
The Arcanum: The Extraordinary True Story
Francis Bacon (1561-1626), though critical of alchemy, compared alchemists to the father who, on his deathbed, told his lazy sons of a sum of money hidden underground in his garden. After his death they began digging in hopes of finding the treasure. They found none, because (as the father knew) there was none, yet they enriched themselves with a large crop that their inadvertant plowing made possible. A cute little story, but this book is the story of Bacon’s anecdote come true. In trying to create gold alchemically, a brilliant proto-chemist invents porcelain. Or rather, re-invents it, since the Chinese had been doing just fine making porcelain for hundreds of years before.
GPS-ified road trip photos
Here’s a nice example of a what photo albums will look like in the future.
Ron and Taylor’s Road Trip takes all of the photos taken during a road trip and puts them, through the magic of GPS, in exactly the right cartographic context. The first page all by itself tells a great story of where the trip went and what was seen. GPS-enhanced cameras seem like such an obvious idea to me, I’m surprised we haven’t seen more of them on the market. You’d never have to ask the question “Where was I and when did I this picture?” The next thing I want to know is exactly which way the camera was pointing. Then I want a back massage and strong drink. The wish list goes on from there, but I’ll leave it at that.
