Meet the TrueCrypt

Wanna encrypt your data ? Well there are lots of solutions, but the better is the TrueCrypt! Think in a tool that can encrypt your entire pendrive, your data partition, can create and mount a kind of encrypted “container” and encrypt your entire system partition (this last one you have to run windows on it). Well and if I say it is € 0,00, yes this is real.

Visit the site of this wonderful tool: http://www.truecrypt.org/

It’s good to notice that this open-source tool runs on Windows, Mac and Linux!

ps: in a few days I will post a mini tutorial of its use! =)

Battery Life on Ubuntu

To get some info about your battery life, open your terminal and enter:

$ cat /proc/acpi/battery/BAT1/info

this will return you some useful info!

take a look at this output:

1. present:                 yes
2. design capacity:         4400 mAh
3. last full capacity:      4300 mAh
4. battery technology:      rechargeable
5. design voltage:          11100 mV
6. design capacity warning: 0 mAh
7. design capacity low:     129 mAh
8. cycle count:          0
9. capacity granularity 1:  1 mAh
10. capacity granularity 2:  1 mAh

Well well, at lines 2 and 3 we can notice that there is a gap between the values. If you charged completely your battery and it always doesn’t fit the same value, it may mean that your battery has lost some of its capacity! =/
