Comment Possible meaning (Score 1) 486

Students graduating from the University of Waterloo's Math Faculty are invited to make one or more graduating pledges to support U(W). One of those pledges is the Dean's Prime Number Club, which confers upon you your very own Prime Number.

As others have noted, the binary sequence is a palindrome prime number in base 2. David Johnston is U(W)'s out-going President. It's likely that the Math Dean's Office has awarded him his very own Prime Number as an honorific (or for completing the pledge!) and he has chosen to incorporate it into his personal Coat of Arms.

I am unable to find the Prime Number registry online or in fact any mention of it at all, U(W) web pages about pledges aside. Digging out my old papers I see that the letter awarding one's Prime Number merely says "Here it is in the box at the bottom. Congratulations!" Perhaps the Dean's Office will confirm tomorrow.

...Stu, hopefully not the only member of the Dean's Prime Number Club reading Slashdot...

Comment Re:Likely major fail with approach... (Score 2, Informative) 629

However, having had many protracted discussions with friends of mine who are teachers, I've found out that in many districts the principals identify the best teachers in the school themselves and assign the worst students to them. The "sampling" of sorts is most likely very unrandom and biased.

I'm certain this isn't captured in these test scores or being adjusted for. This would be difficult if not impossible to tease out but might be by looking for the expected patterns, i.e. a student's poor performance is less than it was with a previous teacher.

If you had RTFA you would have known that this is accounted for. The metric looks at a student's relative performance. A bad student, given an average teacher, will do just as poorly at the end of the year as at the start. Ditto for a good student, an average student, a corpse, a bird, a principal.

If you want a screen you can draw on, those have been available for years. Hopefully you have not been waiting for one. But a 12-inch Cintiq costs 2x what the iPad costs, and considering that many people who are currently using Wacom tablets don't use the pressure (they're just making Photoshop selections) it would be a waste to prioritize pressure on an iPad at this time.

There are ideas out there about how to make pressure work on devices like iPad but it is not happening yet.

Also, keep in mind that the Mac will get touch in the near future. That is when we may see Wacom being made obsolete by stock Macs.

"The burglary was over and the burglars had gone. No one was in any further danger from them."

Until the next day, say.

I knew someone would reply with this. Yes, we can all cheer personally that the bad guy is off the street and they're not going to tie anyone else up. But from a legal point of view, once the immediate threat has ended, you can't use force in self defense.

My point was that this is not an example of "Britain locking up people for defending their families", especially with the implied contrast to the United States. Legally, they locked this guy (and his brother) up for chasing, beating, and permanently injuring a guy in the street. Had the same beating happened while they were still in immediate danger, the legal situation would've been entirely different.

That is the original article, but it looks like there has been a happy ending since I read it last. Looks like he has been released. I'm a bit surprised, but gratified. There was a lot of publicity at the time and it looks like it had an effect.
I read crime reports from all over and occasionally see similar stuff from across the pond. I dont have any others off the top of my head though.

Comment Don't forget about meatspace (Score 1) 1

It's great to have all sorts of technological tools to enable communication, but you can't forget how important it is to get people to engage in face to face activity. I have seen some really effective use of lunches, mixers, picnics and other events that brings people together outside of the work environment and builds better work relationships as a result.

Your crew could take the task on themselves, but I would suggest recruiting somebody for the job, hopefully with some sort of event planning experience and decent communication skills. Getting them to engage all of the tools you already have in place would be essential, so it wouldn't hurt if they were familiar with social media

I love Opera Mini! I use it all the time, but if the site has too much junk, it still takes forever to load, even in Opera. I'm actually pretty impressed with the second rev of their version 5 beta. The first version really stunk, but the new one is quite slick, and I especially like the addition of copy and paste.

To tell you the truth, I have no idea how people tolerate the stock Bold browser - that thing is awful.

Independent research shows there is risk of brain tumors from cellphone use

Despite the systemic-protective-skewing of all results in the Interphone studies, significant risk for brain tumors from cellphone use was still found
Concern 6
Studies independent of industry funding show what would be expected if wireless phones cause brain tumors
Concern 7
The danger of brain tumors from cellphone use is highest in children, and the younger a child is when he/she starts using a cellphone, the higher the risk
Concern 8
There have been numerous governmental warnings about children’s use of cellphones

Comment Re:A note about the study (Score 0, Troll) 211

Legit torrents, like Jamendo and Linux distributions, usually use their own trackers. So the study will naturally underrepresent legal BitTorrent content.

Let's be realistic about this.

The geek may download the nightly build more often than he changes his boxers or briefs.

But you won't go far wrong in assuming that the DVD sized P2P download is a pirated game or a video.
