By Amy Cavender. Time flies. It’s hard to believe it, but it’s been four years since I first took a look at a Linux distribution called UberStudent. Back then it was in its 1.0 release, called “Cicero.” The latest release, “Epicurus,” came out in mid-January, with a version number of 4.1. More...

By Ryan Cordell. If you’re like me, when shopping for…well for almost anything…you can be paralyzed by choice. If you need a new set of headphones, there are just so many options out there, and so many blogs or forums in which experts and consumers will discuss in detail the pros and cons of any given choice. We do a bit of that here at ProfHacker, of course, and we hope our recommendations are good ones. More...

By Natalie Houston. Today marks the start of the #1ineveryclassroom public awareness campaign by the UK-based Colour Blind Awareness organization to point out the prevalence of colorblindness and the need for greater awareness on the part of educators. More...

By Adeline Koh. One of my more unhealthy habits is to slink over to the vending machine in the late afternoons, especially when I’m teaching (I can’t help it, I need to replace the salt and electrolytes I burned off! Ha.) The problem with the vending machine offerings is that they aren’t very filling or very nutritious, no matter how tasty they might be. But after a day of teaching and meetings, I really, really need something delicious, so the usual granola bar won’t do. More...

But put another way, in classical Greek, and you have the serious malady named by the American psychiatrist Isador Coriat a century ago: triskaidekaphobia. More...

By William Germano. You’ve got to feel sorry for the Right Shark, who unlike the Right Whale, really was on the right, and in the right, too.
As readers of Lingua Franca know, the fabulously expensive entertainment known as the Super Bowl consists of two frequently interrupted episodes of male violence that sandwich the thing many viewers turn in for. I mean, of course, the Halftime Show. More...

By Geoffrey Pullum. Bryan Henderson’s hobby is eliminating comprised of  from Wikipedia articles. Just another quixotic purist struggling to retard linguistic evolution? That’s what people seemed to think I’d say, as they busied themselves sending me links to Andrew McMillen’s Backchannel article about Henderson. But the situation is subtle, and head-swirlingly complex. I’ll explain as clearly as I can. Comprise yourself—I mean compose yourself. More...

By Ben Yagoda. I picked up The Philadelphia Inquirer last week and read an article by Jeremy Roebuck about how a judicial ruling had revived the onetime local news anchor Alycia Lane’s long-dormant lawsuit against her former station. Here’s the line my eye was drawn to: “‘We’re back,’ Lane’s attorney Paul R. Rosen singsonged in an interview Friday, giving his best Poltergeist impression.” More...

By Lucy Ferriss. I heard the news of Harper Lee’s new novel—or, to be precise, of the planned release of the companion novel to To Kill a Mockingbird that she penned many decades ago—while I was doing research at the Missouri Historical Library and Research Center. My own subject, still vaguely outlined, is the Louisiana Purchase Exposition of 1904, now more than a century in the past.
