ISO mounting will be cool. It'll probably be very easy to detect/deter so it'll be useless to pirates.

Guest account- Windows already has a guest account, this is the ability make guest accounts on demand. OS X's guest account is just enabled/disabled, which can also be done on Windows.

Speed is judged by hashes per second. Some of the very top cards don't perform as well as slightly "slower" cards because the code isn't optimized for them. I wouldn't use any card under 35 or 40 million hash/s. (A good CPU will get 2-6 Mhash/s)

I'm not sure if the Arduino was an interface or if it was an example of hardware. I'd find the thread but HackADay is freezing on me.

Pretty much.

It's not Anonymous transfers, each user is anonymous. You have a bitcoin address to store bitcoins and make transfers with. Only you get this address, it's created using a private key that you hold. If the vendor runs with the money you can't do anything about it but you can definitely prove that you gave him money.

Don't bother unless you have a powerful GPU. Anything but a top-end ATI card will waste more in electricity than you mine. NVidia cards don't run very quickly. CPU is useless.

USB host mode? Did you just say USB host mode? PARTY TIME! No more driver modding and chrooting to get crappy USB support. I'm going to tape my portable hard drive to my phone. "32GB iPhone? Check out my 320GB Android phone".

Who would go through the trouble of setting up an access point? Throw the NIC into monitor mode and sniff for tokens from all unsecured APs within range.

I haven't heard of anything like that. Android can auto-connect to pre-established networks but not new ones.

7 hours is my lowest time without being overly tired. Even 7 hours and 10 minutes leaves me falling asleep during the day. 8 hours is ideal, I'm not tired at all with 8 hours.

That's a lot of dough. With that I'd get either a MBP or one of the high-power Asus laptops with GPU switching. If you wanna keep it cheap, the ASUS U31JG-A1 is quite powerful (i3 and a GT 415M, vroom!) but has good battery life because of the GPU switching.

Cheapest possible? I say a Phenom X2 or X4 barebones kit. i3 makes a very good barebones kit but it's usually $100 more expensive. A Phenom should be able to handle 1080p no problem.

I don't know about plain baking soda but deodorant made with baking mixed in works very well.

I'm surprised that alternate app installation isn't on the list. Nothing's more fun than installing APKs downloaded somewhere other than the market.

Half of Gizmodo could make a better tank than this. C'mon guys, let's build a tank and go fight those cartels.

That's sweet. Now adding tape to my secret agent spy kit.

I avoid putting bleach in the toilet. Bleach will react with both ammonia and acid (found in urine) and create toxic gasses.

Actually it does. I've had baking soda and vinegar take junk off of dishes that was impossible to remove by scrubbing.

I just wing it.
