The picotux 100 is the world’s smallest Linux computer, only slightly larger (35mm×19mm×19mm) than an RJ45 connector. Inside, there is an ARM7 CPU at 55 MHz running uClinux kernel 2.4.27 and Busybox 1.0. Two communication interfaces are provided, 10/100 Mbit half/full duplex Ethernet and a serial port with up to 230.400 baud. Five additional lines can be used for either general input/output or serial handshaking.

This is my first build using an arduino microcontroller. I wanted to create a simple tone output device along the lines of the 555-based atari punk console, but using solely the mcu as the tone generator. Unfortunately, that was just too simple a task with a microcontroller to play with–it was done in about five minutes and my mind was already forging ahead with a bunch of stupid ideas.
Since coding the arduino is simple, I decided to set up eight tone “slots” and then sequence through them. A frequency knob would control the freq of each slot, and a separate tone duration control would allow me to get awesome eighties video game tones. Figuring out the component wiring wasn’t too tough once I’d figured out the basics of reading analog pots and digital switches.
I also thought it would be fun to add a 2 line x 16 character backlit LCD display. The one I used is from sparkfun electronics and includes a serial I/O board so writing to the display is super easy.

G.ho.st provides every person in the world with a free Virtual Computer (VC). Like a Windows PC, or Mac, the VC is a personal computing environment which includes your desktop, your personal settings, your files and your choice of software applications. But unlike a PC, your VC is not installed on one physical computer – instead it is stored in professional data centers across the Internet cloud, and is accessed from any Internet browser in the world. From any computer, open the browser to G.ho.st , enter your username and password, and continue using your VC from exactly the state you last left it in.
Your G.ho.st VC has several advantages over a PC :
The G.ho.st VC is currently in public “alpha” – the VC is already stable and usable although it does not yet have a complete set of applications, services and widgets associated with it and there are a few bugs. The bugs will be fixed and application added rapidly over the coming weeks.
The World’s Most Efficient FREE Defragmentation Software
What’s the primary cause of slow/unstable PC performance? It’s disk fragmentation. IObit SmartDefrag helps defragment your hard drive more efficiently than any other product on the market –– free or not.
Features of this powerful, award-winning defragmenter program include:
Let’s face it, deciding to nuke your existing operating system installation and replace it with a completely different OS isn’t the sort of task that you should approach lightly. One of the barriers to Linux adoption is the fact that many people find the idea of wiping their Windows installation a daunting thing. Sure, the widespread adoption of the Live CD with allows users to boot into a working Linux environment has made taking a Linux distro for a test drive easier, but a Live CD experience falls far short of what you can expect from an installed Linux experience.

Meu Eclipse estava travando e fechando após um tempo de uso, lembrei logo que poderia ser algo a ver com o uso de memória para o mesmo, configurei então os parâmetros o eclipse.ini:
-showsplash
