This is a major problem. It took me forever to figure out how to close the app. You have to log out from your account to stop it.

1) Click the "My info" button at the top
2) Click on the menu button
3) Click the "Sign out" option

That's the only way beyond forcing shutdown or rebooting to quit out. Even more annoying, it won't save your password if you don't have it log in automatically.

As the article states, the source only supports the newer 11n chipsets, which is currently BCM4313, BCM43224, and BCM43225. G and lower chipsets still have to use the older crusty stuff. Still something good to look towards the future for. I'm going to be keeping an eye out for routers that have those chipsets and are dd-wrt compatible in the future when I move to N now.

I graduated from the College of Engineering at the University of Cincinnati not to long ago. For both our calc and physic classes, we were pretty much limited to a TI-89 or TI-92. You could use below the TI-89, but it didn't have enough functions for the higher level calc, so it was pretty useless. I do remember some students would bring in other makes and most times (not always) they were not permitted to use them. The professors said they didn't know the models and were afraid they might have additional features which would permit cheating. Also don't go to high in the TI line-up. Some also come with keyboards, which everytime a student came in the room with those, the calc was banned. The TI-92 was pretty much the safest calculator which had everything you needed for both physics, calc IV, and beyond.

Once you get into signal processing, you will be using matlab or equivalent software.
