I am so indebted to the community

As someone who learned computers on his own, I always acknowledged the value that the Free Software movement has brought. The accessibility of these topics, which are only supposed to be part of text books and schools, is available for anyone and everyone who has the resource and passion to do it.

But this past week, 2 things made me pretty impressed with the maturity and quality of work that we do.

rrs@zan:/media$ sudo lvextend -r -v -L 100G /dev/BackupDisk/DATA

I didn’t have much hope that this extend operation would succeed. But it did. When I initiated this operation, in the background, I had the backups being synced parallely (which actually made me resize my volume. :-)

The other item which made me happy yesterday was Audacity. Once upon a time, when I needed to split a music file to cut a ringtone out of it, I ’d go looking for software that could do it. Then I would hope that one of those software vendors have a fully working version and not a demo with just 5 seconds clipping. Cowon was one media player I can recollect I’ve used to split audio files.

But in this case, I had a different requirement. I needed to increase the dB of my ringtone file so that it sounded really a ringtone (Example: Bourne Ultimatum OST). Audacity, not only did it do the job, it did it for me in just 3-5 minutes. And all with just button clicks. For a n00b with no experience in that domain, I was really impressed.
