What exactly is an open-ended problem? It’s a problem with no obviously right answer. This uncertainty causes great discomfort for many that are accustomed to approaching problems as if there is a single right answer. This, however, is a sign of underdeveloped critical thinking ability.

Since Apple has been doing a great job lately at meeting consumer demands, regulators will start harassing them for the crime of giving consumers what they want. Apple’s competition will be happy to encourage them. The eMusic founder thinks the rumored Apple music subscription model won’t pass the anti-trust test in the EU if […]

Kevin Yamamoto posted his forthcoming article, “Banning Laptops in the Classroom: Is it Worth the Hassles?” (57 Journal of Legal Education (2008)), on SSRN. Here is the abstract.

Over the last several years law school classrooms have seen an explosion of student laptop use. Law professors have allowed this by default, generally under the pretense that laptops make note-taking easier. However, many professors complain that students use their laptops to play games, watch movies, or if they have an Internet connection, to do web surfing and e-mailing during class. This paper presents my experience in banning laptops from my classroom in the Fall of 2006, the first time it was done at my institution. The article covers the reasons for and against allowing laptops in the classroom, my reasoning and procedure for banning them, perceived differences in the classroom experience and relevant student comments from my course evaluations, which were overwhelmingly positive to the laptop ban. Also covered are the cognitive psychological reasons in support of banning laptops. Studies show that lower grades were correlated with increased student web browsing during class (Grace-Martin & Gay, 2001; Hembrooke & Gay, 2003), and the amount of time which students used their laptops for tasks other than taking lecture notes (Fried, 2007). MRI studies of the brain indicate that the brain stores information differently when distracted, which occurs when students attempt to multi-task in class (Foerde, Knowlton, & Poldrack, 2006). The science of note-taking is also covered, which indicates verbatim typing may interfere with learning (e.g., Kiewra, 1991). The paper concludes by urging law school professors to review why laptops are allowed in their classrooms and, unless they feel that laptops increase student learning, to ban or heavily restrict their classroom use.

A new warning may soon be issued by all laptop computer manufacturers and the moguls of the recliner chair industry. We are already warned of the perils of using plastic bags as toys, not using the computer in the bathtub or near water, and the possibilities of the chair tipping over if one stands on it, or relaxes too hard or too quickly. I have discovered yet another legitimate cause for concern and shall report it to anyone who will attend to my natterings.
The basic danger stems from the design of the recliner chair itself. In order for the footrest action of the chair to work properly, a mechanical system of thin, moveable steel bars and pivot points is required. When the back of the chair is pushed toward a reclining position, the footrest rises into position to support the user’s legs. The reverse action occurs when the occupant desires to sit upright or to arise from the chair. One might reasonably ask, “What’s wrong with that? That’s what it’s supposed to do.”
I will, of course, tell you. You don’t believe I’d get this far into a perfectly good rant without complaining about something specific, do you? The danger arises when the laptop computer and the collapsing action of the chair required for the user to arise happen concurrently. I dislike resorting to the use of hyperbole or fear-mongering, but I must state that the scissor-like action of the mechanism attached to the footrest presents a real and present danger to those of us who use a laptop, with power supply and Cat-5 Ethernet cables attached, while seated and blogging in blissful ignorance.
Very recently, while arising quickly from the chair, I discovered the more personal and real-world meaning of the phrase “scissor-like action,” when used in this context. The wires pass close to the footrest mechanism, and in this case, became entangled in it. … The power cord was repaired easily enough with a soldering pencil and some heat-shrink tubing. It was quite a cleanly sheared cut, actually. The Cat-5 Ethernet cable, however, required replacement. Uh-huh. I did that.
Peace, Doc

I sent a network admin an email last week with some links in the body. One of the links was to Sunbelt Software. The admin never got it because their Barracuda Spam Firewall blocked it. Why? Because it had a link to Sunbelt’s website in the body:
