Photo of William Crowther, 2012

I just noticed that a few days ago, a Wikipedia user uploaded a photo to the bio for computing history legend Will Crowther. The caption reads “Will Crowther in fall of 2012 in the Shawangunk Mountains.” A bit of Google-fu leads to several photos showing Crowther is still climbing (the hobby he had long before…

Lego goes steampunk

Be still, my nerdy heart. Steampunk — which has inspired books, art and fashion — hinges on the idea of a future in which we use steam, rather than oil or electricity, as our primary source of energy. Still confused? Think 19th-century fashion and technology, but applied to a futuristic world. Or check out bing…

Brain, Interrupted

In most situations, the person juggling e-mail, text messaging, Facebook and a meeting is [not multitasking, but] really doing something called “rapid toggling between tasks,” and is engaged in constant context switching. As economics students know, switching involves costs. But how much? When a consumer switches banks, or a company switches suppliers, it’s relatively easy…

Multitasking while studying: Divided attention and technological gadgets impair learning and memory.

Fairly early in the semester, I can spot the students who will struggle to complete big assignments, because they are often the same ones who can’t resist the urge to check up on their Facebook friends. Students’ “on-task behavior” started declining around the two-minute mark as they began responding to arriving texts or checking their…

Grading writing: The art and science — and why computers can’t do it

Tech companies and university administrators get excited from time to time about the value of software that purports to evaluate student writing. This article does a great job explaining exactly what it is that writing teachers do when they respond to student writing. (We’re doing a lot more than looking for misplaced commas.) The past…

Churnalism Search

At the University of Virginia, one summer when I had a summer job writing press releases for a theater company, and I also volunteered for one of the campus papers, I was amused to see how much of my press releases would appear under a different author’s name in the competing student paper. One time…

Why No One Clicked on the Great Hypertext Story

It’s not that hypertext went on to become less interesting than its literary advocates imagined in those early days. Rather, a whole different set of new forms arose in its place: blogs, social networks, crowd-edited encyclopedias. Readers did end up exploring an idea or news event by following links between small blocks of text; it’s…
