I'm a student at UMD right now, and pretty frustrated to find out about this. IMO, the university should do a lot more than just providing a year's worth of credit monitoring, because once that year is up and people forget/ch

I've been running into this problem with my 2013 MBA. It happens on wake, and the only that fixes it is a reboot. I'm getting pretty fed up with the issue since it's tanking my battery life and there seems like nothing I can

The "too much time has passed" bound on each iteration guarantees that you don't end up running an iteration forever, and makes the algorithm O(2^N), since the number of programs up to N bits long is 2^(N+1) - 1.

The vast majority of Crossfitters are not at a level of physical fitness and mental toughness that would put them at risk of rhabdo after a WOD. They'd throw in the towel long before "meeting Uncle Rhabdo" under most normal c

I've been taking notes in LaTeX and keeping them in source control recently. I still prefer to take notes during lectures by hand, but usually within a week of a lecture I'll transcribe them into TeX. It takes a lot of extra time,

It's a sad situation, and the officer never should have fired his sidearm at the dog, but to be fair to them, they didn't just shoot the dog with no provocation - the dog lunges 2 or 3 times at the officers with clear aggressive i

MBA's really are the best ultrabooks money can buy right now. I'd say the X1 Carbon from Lenovo comes close, except if you want comparable specs you'll have to shell out a lot more cash, and that's pretty much the same s

Sometimes it's not so straightforward to split up large into many small tasks. A lot of the time these steps will depend on other unpredictable factors, which leads to a lot of backtracking and adjusting my to-do list down the road when I s

I think the rigidity of this system is its biggest drawback, as is the case with most productivity systems. For example, if I have two large projects that I need to get done and I only write down one, the other is going to keep nagging at m
