Everything Can And Will Be Hacked: digital testing systems

classroom testIt’s an old story, but worth bringing up because of the fundamental truth it teaches us. Back in the nineties, a company called Edutron Systems was trying to get schools to upgrade from the hopelessly antiquated pencil-and-paper test system to its disk-based gizmo, with predictable results:

It took all of one test for the students to find a flaw in the system: if one received an unsatisfactory score, he could simply retake the test. Classroom Assistant didn’t bother recording how many times each test was taken. Sure, retaking the test several times was time-consuming, but generally worth the effort.

On the second test, students found a slightly easier workaround: they could simply run a different test. Since the results screen did not indicate which test was taken, all one needed to do was open up the “Test Taking Tutorial” test and pass it with flying colors.

It gets worse as it goes on, of course – kids are resourceful when they want to avoid something onerous.

And so, the lesson is: everything can and will be hacked; the greater the motivation for a successful hack, the faster it will occur. Maybe time to back off on those ambitious plans for biometric passports, eh? [story via Hack A Day] [image by ccarlstead]

Scented laptops

floralApparently for real, from PC maker Asus:

Floral Blossom is pink with a flowery smell; Musky Black sports graffiti art and emits an earthy musk; Morning Dew comes in pastel green and offers that refreshing early a.m. je ne sais quoi; and Aqua Ocean gives off an aquatic aroma and comes with sky and wave imagery on the cover.

MediaBistro, unimpressed:

I can’t wait to get on a plane in a middle seat in coach surrounded by this stuff.

Spimes – making computers more recyclable

junk computer hardwareComputer hardware can be a real bitch to recycle, as attested by massive landfills in developing nations and closer to home. Someone in an organisation called EPCglobal has evidently been paying attention to Bruce Sterling, because their plan to tag all new-built computer components with unique RFID chips containing data about how, where and when they were made sounds pretty similar to Sterling’s “spimes”.

Now, if we could just give them GPS devices so they could navigate themselves back to their point of manufacture…

Translating genetic information into music to diagnose disease

gene music Computers are very useful for analyzing large quantities of data, but presenting that data to humans in a useful form is an ongoing challenge. (A challenge that predates computers, actually: that’s why graphs were invented.)

Here’s an intriguing new way to examine data: turn it into music. Gil Alterovitz, a research fellow at Harvard Medical School, is developing a computer program that translates protein and gene expression into music: harmony represents good health, and discord indicates disease:

The first step in the gene-to-sound conversion was to pare down multiple measurements to a few fundamental signals, each of which could be represented by a different note. Together, the notes would form a harmonic chord in normal, healthy states and become increasingly out of tune as key physiological signs go awry, signaling disease.

He found, for example, that “when set to music, colon cancer sounds kind of eerie.” You can listen to some samples online. (Via KurzweilAI.net)

Alterovitz hopes the system could be tuned to identify other diseases, and might have applications outside medicine: it could be used to simplify information for air-traffic controllers or in other situations where large data sets have to be analyzed.

Not only that, a DJ in the Boston area is apparently interested in playing Alterovitz’s “music” in local bars.

Perhaps he could call it “Forever in Blue Genes.”

(Ouch, a Neil Diamond reference. I’m showing my age, aren’t I?)

You Are Officially Mentally Disturbed

The American Journal of Psychiatry has officially declared [courtesy of a Wired.com article] that “Internet addiction appears to be a common disorder that merits inclusion in DSM-V [Diagnotic and Statistical Manual of Mental Disorders]”.  Yup, that’s right.  If you get angry because you missed that raid on Onyxia’s Lair, then you could very well be mentally disturbed.

The biggest problem I see with such a claim is that the basis for most of their research is from people who spend more than 23 hours a week on the computer.  23 hours?  That’s it?  This figure would include nearly anyone who works for a business that is any kind of computer-dependent (and that includes most of them if only through internal emails and the internet).  It’s one thing to use a computer 23 hours in a week; it’s another thing entirely to spend 23 hours in a day playing video games (which is the root of much of this kind of research).

It just seems like yet another blow to geekdom for people to be able to say, “well you have a disorder because you like your computer too much.”
