Speaking as someone that teaches second semester CS to 300 undergrads a semester, there is value in both.

Advantage Paper: The computer is a crutch. If you know it, you can write it. You are going to to have to do this in coding interviews. Requires no infrastructure to give an exam without cheating. (I actually don't have the space/computers to give a computer exam to hundreds of students at a time.)

Advantage Computer: I/TAs don't have to grade it, I can just use gradescope.com and students won't argue with me for partial credit.

What does the inside of a used implantable defib smell like? I know Kevin knows :)

It was a frustrating experience for sure, but there is an easy solution: switch to any one of the MVNOs or a prepaid plan from the carrier. Figure out what network they are riding on top of that matches your preference, then switch.

I picked GoPhone (from ATT), but straighttalk wireless, or others will work just fine for you and are likely cheaper.

Good luck, but this is an easy one to solve.

That's why I use freemyapps (But then again I work there so I might be *slightly* biased :)

There is a fairly straightforward way to locate the cameras if you have a bit more time than me. Using the time of the sunrise and sunset (and the length of the day), you should be able to get a decent fix on the location (people use the same technique on whales and sea turtles.)

On paper it is mostly a great idea.

We had a paper on some tricks to play in file systems to make it perform better:

But when you get down to it, churn is your biggest enemy. If you look at the rate at which people join and leave p2p networks, the amount of replication you need to do can use a lot of bandwidth. Every time a user quits (or drive crashes etc.) all of the data they were storing for others must be replicated again. If they aren't available online for a while you have to assume they have left the network and replicate proactively. See the paper for a few sample calculations based on the churn found in systems like kazaa and skype.
