Python Computer and Raspberry Pi

Preparation

On July 30, I received my first Raspberry Pi, purchased at Element 14. After a one-month wait, it arrived in the mail, albeit late from Belgium – 9 pm. In reality, it arrived around lunchtime, but since I wasn’t home, the postman left it as regular mail.

P1060883

The box is small, like a credit card. In fact, I found the computer amidst other letters.

Adventures with FSCK

Back-ups are always a good idea… this week I lost two HDs. One on the PC, I was able to recover all the data and transfer it to a remote server. The other, my Ubuntu, Tambaqui of war.

I arrived at work in the morning and saw that the computer was turned off. As the Tambaqui is also a small server, I usually leave it running. I plugged in the fish and the boot occurred normally (I always say that only what was previously working perfectly will give you problems :-), otherwise nobody would come up with that worn-out excuse: yesterday it was fine!). Looking at the files after booting, I saw that there were several files with strange names with ??? and !!!!… a sign of file system problems, but fsck swore everything was okay :-)

Firefox Ubiquity

The Mozilla Labs is experimenting with a new Firefox extension called Ubiquity (http://labs.mozilla.com/2008/08/introducing-ubiquity/). This extension allows you to open a command window in the browser and perform very interesting mash-ups.

The test version, see the video, brings features such as quickly searching Wikipedia, searching addresses on Google Maps and others. The best part is that users can define new commands, see the tutorial (https://wiki.mozilla.org/Labs/Ubiquity/Ubiquity_0.1_Author_Tutorial).

If you want to insert maps into your Gmail, translate passages from web pages, search for books on Amazon without leaving the current page, Ubiquity may have been made for you.

Backups

Time passes and even computers get old. My Windows is nothing to talk about…

After I started using the Mac, the PC was handed over to other users in the house. The party began with cheerful underwater themes, 3D fish, and weird things like that.

Unfortunately, a computer doesn’t get better with time… and it got ugly even to turn on. I’m taking advantage of sacrificing my installation and starting another from scratch. But that’s not so simple.
