Comment SVD and PCA to determine correlation (Score 1) 271 271

The linked PDF file gives absolutely no indication on the method used to determine correlation. Unless you've done some singular value decomposition and principle component analysis on a list of factors that could contribute to productivity, I don't really see anything scientific about this study. Who's to say that productivity isn't more strongly correlated to types of industry (take note of the very bottom of the study, where healthcare and non-profits have more female CEOs whereas manufacturing has more male CEOs)?

Comment Nonsense -- make your own test suite (Score 4, Insightful) 169 169

Why would you only test your code via normal use? Why wouldn't you just create a test suite that actually tests all the scenarios? In the case of tetris, you can simply force a sequence of pieces that will enable you to reach the scenarios described in the article. Or you can even start the game with a pre-made board.

Comment Did Apple screw GTAT? Or vice versa? (Score 1) 171 171

So which is it? Did Apple get GTAT's hopes up on using sapphire displays, sends them money, then decides they aren't going that route anymore leaving GTAT with facilities that have no use? Did GTAT have to invest some of its own money to get the production rolling on the sapphire screens, presumably because Apple's near 600 million isn't nearly enough? So is this why they are filing Chapt. 11? Or did GTAT burn to all that cash, only to have nothing to show for it and pissing off Apple in the process?

Comment Why bother with internet testing (Score 1) 95 95

I am pretty sure that cheating back in the day occurred fairly regularly, but I am willing to wager the farm that, relatively speaking, cheating on computer-based exams today is much easier than cheating back in the old days of pencil and paper. Just take for example the smart watch. It doesn't even have to be an iWatch or the android equivalent. In fact, for a cheater, it's even better if their devices were NOT the typical ones so that they don't set off the ever-watchful proctors. Watches with wifi enabled can be a means for people to get answers much more readily than the old techniques of sneaking in a cheat sheet or whatever methods were used.

Comment What happened to serious research? (Score 1) 126 126

A million dollars? Really? It took us two years to finally get a little over half a million from the NSF for a program to help women and underprivileged kids get a foot hold into math, science, and engineering programs at our university. At least the money is going toward a good cause. I fail to see how the fruits of the Indiana University grant is going to benefit anyone other than the PI and CoPIs getting funding from this grant.

Comment Study needs to consider what people do with notes (Score 1) 191 191

It's not the actual notes that makes a big difference, but what you do with those notes. Most students just take notes and that is the extent of the usefulness of their notes. A much smaller number (I imagine) actually make use of those notes. I cannot count the number of times students come into office hours and, when asked if they refer to their notes, say "no." Regarding those who think LaTeX/TeX is a longer process than taking notes. I took notes on my laptop in grad school for almost all my classes. Diagrams are easily done by drawing them (as a sketch) either on paper or a simple graphics editor to be made nicer when going back to review my notes (see paragraph above). It is much easier to type in one's own words an explanation of what is written on the board (which is often a professor's shorthand) than it is to write it out by hand. As for copying verbatim, typing (even in LaTeX) can still beat out handwriting when it comes to formulas. Lastly, when typing up notes (and done correctly), one can easily review (on the spot) the notes taken (esp. if using LaTeX/TeX) since each few lines of tex can be previewed with a few keystrokes.

Comment Another stupid idea that flops before takeoff (Score 1) 347 347

So just buy it for your mobile phone or tablet and stream to your TV. Most of the smaller have resolutions that are good enough for "typical" TV-sized displays. A better pricing scheme would be for the actual resolution. E.g. $1 for 640x480, $2 for 1024x768, and scale upward.

Comment Study slightly flawed (Score 4, Insightful) 103 103

A better study would be to analyze how the SC2 pros perform as they age. There is a big difference between the amount of free time a college student has to devote to playing a game and improving his skill vs. someone with a family and job to maintain. The article suggests that age is the factor in the decline of skill, when what it really shows is that most folks are likely to have less time to devote to a game once they leave college and take on real jobs and have kids.

Comment The justices should decided based on law only... (Score 2) 192 192

The article suggests that the justices are wavering because there are reservations about the repercussion of their decisions on existing software companies. The issue I have with that is that they should NOT be decided based on the repercussions. Their decision should be made as a matter of law.

Comment Be a better parent (Score 1) 321 321

I think the real problem is that parents want to use a phone or tablet as a pacifier, so they don't have to parent the tykes.

Ah yes, the rallying call of the childless. I'm sure that if you ever have kids, you'll have the means and inclination to devote N hours of your own time every day simply to keeping them entertained.

I have kids of my own, and we also have several tablets, two iPhones (my wife and I each have one), and many gadgets in the house. However, we don't mix tablets/phones in the sense that if I ever have to enter a password into a tablet, that particular tablet does not ever get used by the kids. But you don't need to even have separate tablets (i.e. one for you and one for them). If they ever ask me to enter a password, the answer is no. When my toddler plays with my phone, I make sure that it won't ever get messed up when I get it back from him by taking precautionary steps (e.g. turn off emails, make sure everything requires passwords, etc.) I don't just hand them the device and cry to Apple when they break it.

Then there's also the question of "keeping your kids entertained." You don't need to devote hours of your own time. There are myriad types of toys to entertain your kids -- and even educate them while they're playing. If your tablet is causing problems, then perhaps they could use something else as edutainment. Get them puzzles, coloring books, reading books, etc.
