Comment Re:Launcher barrels rifled! (Score 1) 117

Mr. Elm:

That's a good point about the rifling. It appears that the Defcon fellows are using flare launchers, which, anecdotally, are described as smoothbore.

I dunno why flare launchers aren't rifled. Maybe the need for accuracy in shooting a flare is low: if it goes UP, instead of sideways, it's probably considered a success. The energy expended on making it spin could arguably be better spent on making it fly.

200 Students Admit Cheating After Professor's Online Rant Screenshot-sm 693

Over 200 University of Central Florida students admitted to cheating on a midterm exam after their professor figured out at least a third of his class had cheated. In a lecture posted on YouTube, Professor Richard Quinn told the students that he had done a statistical analysis of the grades and was using other methods to identify the cheats, but instead of turning the list over to the university authorities he offered the following deal: "I don't want to have to explain to your parents why you didn't graduate, so I went to the Dean and I made a deal. The deal is you can either wait it out and hope that we don't identify you, or you can identify yourself to your lab instructor and you can complete the rest of the course and the grade you get in the course is the grade you earned in the course."

That's really interesting, thanks. The main dictionary (oed.com) is $295/year. I didn't know they had a concise one for free.

And it really is concise. One (really good) definition. Not 37 links, like the Google dictionary.

Not that there's anything wrong with 37 links. But sometimes I just want to want to know the definition of the word.

Comment I dunno, man. Snow is heavy (Score 2, Insightful) 456

A couple of years ago Burlington, VT received 25.7 inches (0.65 m) of snow in 24 hours. I don't know what the density of snow is (I imagine it varies wildly), but that seems like a lot of weight.

OK, maybe the warm air can support that... but if that were the case, then on days when there wasn't 89 grillion kg of snow on top, there would be some pretty huge upward forces on the tent-pegs.

OK, well, then, there are vents, to let our some of the hot air. But then you waste all that energy heating air that you're venting.

But maybe it all works out somehow.

Comment Downtown Charlottesville, VA begs to differ (Score 1) 259

I dunno about other places. But a pretty good chunk of downtown Charlottesville, Virginia is covered by free municipal wifi, and it works OK. Not everywhere, and no, you can't "seamlessly roam from one hotspot to another," as they say.

But so what? The signal is reasonably reliable where I've tried it, on and near the downtown pedestrian mall, and the throughput is significantly better than that provided by the coffee shop or the library, even with the trees in full radiation-absorptive leafy-mode.

Maybe "municipal wireless" means something more ambitious, like everybody who lives downtown gets a big honking signal even in their basement, and I don't think that's what they're trying to do here. But it sure is useful to be able to assume that, no matter where you get your latte, or slice, or dumpling, you'll be able to get some work done.

That doesn't sound "dead" to me.

Comment Re:1-800-comcast (Score 1) 352

That's a nice thought, and I agree. But after you get through the 18 layers of phone menus... who are you going to talk to? The billing clerk? The tech support person? I guarantee you that their response will be: "Please unplug your cable modem and wait sixty seconds..."

"Caller is ranting about broken DNS functionality" is NOT on their script.

And anyway it's (888) COMCAST (not 800-). I have it memorized from all the service outages we get around here.
