Let Turk research for you

Being interested in, and recently done a fair bit of reading about, human subjects research, this article from a couple of months ago about using Amazon’s Mechanical Turk for running human subjects experiments caught my eye. It’s a pretty neat idea for pulling in volunteers from a variety of demographics, with some obvious concerns – are people who they say they are, and how much effort will they put into the experiment being the major obvious ones. The article gives some nice specific suggestions for avoiding biases, cheaters, testing the correctness of your study, and addressing other issues. If done … Continue reading Let Turk research for you

Best Bots

I’ve noticed that whenever I teach a subject, the news appears to be disproportionately full of stories about that topic (and yes, I do understand that is not the case…). These are some of my favorites I have found recently: I linked to the BigDog project several months ago – Boston Dynamics has outdone themselves, pushing their sophisticated walking abilities into a bipedal robot, Petman. The video on this is amazing! [via many places, including C.] On the opposite end of the spectrum, iRobot has developed a “morphing blob” robot based on a structure of inflatable air pockets. [via many … Continue reading Best Bots

Does not yet wash the bugs off my windows

This is a robotics application I’ve never run into before, but it is actually being used in the Netherlands: a gas pumping robot. The video shown makes it look like it works pretty well too, and while it seems slow the article says it speeds things up enough to actually increase their number of sales per pump. I do wonder how much of that is the fact that, to use the pump, you preregister with your credit card number and preferred type of gas (so that you don’t interact with the robot at all, you just pull up and sit … Continue reading Does not yet wash the bugs off my windows

Data Liberation

The news from earlier in the week that Google is committing to providing users easy and free ways to move their data in and out of Google products addresses one of the concerns I have had about cloud computing. I understand the appeal in terms of expense, and I have had good experiences when I have used Google Docs for collaboration. But often the content being created is stuff that I may want around many years in the future, or also available off-line on a flash drive (we can pretend the entire world is networked, but in just the past … Continue reading Data Liberation

A “fair” schedule lets me sleep in until at least 7

We’ve been talking about various types of scheduling problems in my AI class, so this local article about computer modeling used to schedule sports games caught my eye. It is an interesting constraint problem – not just the number of games, mix of who plays who, and frequency of games, but particular rules based on amount of time needed to set aside for travel and other issues of fairness. It is particularly worthwhile to think about the advantages this system offers when changes occur that make a planned upon schedule no longer acceptable. Often, the human response to that is … Continue reading A “fair” schedule lets me sleep in until at least 7

Fashion PSA

While I am willing to concede that in general, I should never, ever attempt to give fashion advice, I am still comfortable saying that nobody needs eyes painted on the back of their jeans so that their ass winks as they walk. Don’t just watch the first few seconds and stop the video – make sure you skip forward until you see the action/cut boards and the ducks at least. Based on the notes in the Consumerist article via which I found this, the eyes apparently only work if your pants are sufficiently snug. I’m surprised they stayed classy enough … Continue reading Fashion PSA

Same low protein, less chlorine

I am unreasonably excited that King Arthur Flour is coming out with an unbleached cake flour. I love their bread flour, and my entirely-uneducated-bias is against bleached flours. I’m really hopeful that this shows up in my local food store. Sadly, I cannot even find regular cake flour in my local food store, so my hopes are not too high. Anyone who live around me have suggestions of where I can get cake flour around here? My Cake Bible has been pouting at me every time I use regular all-purpose in a birthday cake, but I cannot bring myself to … Continue reading Same low protein, less chlorine

Don’t let them swab you

In a similar vein to yesterday’s post on data, I just noticed this NYTimes story reporting that DNA evidence can be fabricated in a lab to match a target, given a sample of their DNA, or their DNA profile from an earlier sample. Even if it seems expensive and cumbersome to start fabricating DNA evidence to frame people, there are some very interesting legal implications here just from this process being known. While the article says that they were able to fabricate blood that a testing lab processed as if it were from the target rather than the actual source, … Continue reading Don’t let them swab you

Never admit you like Star Wars

I really enjoyed this article about how little information is needed to personally identify you. The answer is, a lot less than you might think, and using more benign information than you might imagine. 1990 census data showed that 87% of people in the US could be identified based on their zip code, gender and date of birth. I found their results on movie preferences even more interesting: “Knowing just a little about a subscriber–say, six to eight movie preferences, the type of thing you might post on a social-networking site–the researchers found that they could pick out your anonymous … Continue reading Never admit you like Star Wars

Looks like a butterfly

As pointed out at Slashdot a couple of days ago, there is a pretty interesting converstation going on over at Wikipedia about whether it is ethical for them to include images of Rorschach inkblots. The inkblots are now in the public domain, so the issue is not ownership. The issue is that the Rorschach inkblot test requires that the images be novel to the subject, so would Wikipedia be doing harm by potentially depriving those in need of psychological help a potential treatment tool. The conversation on the talk page has gotten quite long so I’ve only skimmed most of … Continue reading Looks like a butterfly
