Re: TP-WN722N

According to linuxwireless TP-WN722N requires firmware[1]. Installing the nonfree wireless driver package should solve this problem. The puppy distro comes with firmware, maybe?

Re: Best Database

Should you decide to stick with SQL, I'd recommend SQLite as well.
Otherwise, I personally use Redis for REST API development. The 2.2 version of MongoDB looks promising, too.

Re: Raspberry Pi and the MSP430

hum, then I highly recommend installing a linux environment on your computer through a virtual machine just to get familiar with msp430 programming in gcc. On the other hand, I doubt if the raspi debian/fedora images have compiled msp430-gcc packages in their repos (as far as I know, ubuntu and fedo...

Re: Raspberry Pi and the MSP430

connect them together with the usb wire (or through uart pins, either way works), and then communicate to the launchpad through the uart interface. I assume you know how to program the msp430 under linux or you won't have bought it, unlike me who spent one whole day to get msp430-music to compile :)

Re: gparted how do I hate thee?

Re: Multiplayer Games On The Pi?

im planning to run the mcserver on raspi. It's an minecraft server implementation written in c++, and therefore consumes less memory and cpu than the vanilla server. tried the official testing server, looking good so far. it's going to be great.

Re: Model A or Model B?

short answer: yes. You will be able to connect the raspi to as many usb accessories as you'd like using the usb hub. However, if you connect an usb drive and an usb wifi dongle at the same time, don't expect the speed of either one to be optimistic.

I agree, as long as enabling ssh on raspi is an easy process as JamesH described, not some tedious complicated work that requires editing a 2gb image file or chroot, or even parents would give up on that.
