Discovering Amarok’s features

Must admit than I don’t know about recent features of Winamp, since I haven’t used it much in a year or so, but last time I did, it couldn’t handle file renames. So if I noticed that some file had a name not reflecting track info correctly or I just moved it to a different folder my playlist and library were left broken.

To my surprise when I renamed files and then tried to play them with Amarok it didn’t happen at all. This player has a wonderful feature called AFT: Amarok file tracking. This is simply genius!

It’s somewhat surprising how I’ve got accustomed to Amarok. I remeber I used to miss Winamp in the beginning. But newly discovered AFT and support for listening to last.fm directly in player are really great features.

Those of you being brave but using Windows can also give it a try: Amarok for windows.

Cryptic JBoss error

After some weeks I tried to run JBoss again. I was welcomed with the following exception:

And I know it was working before! Suspected Java update 7 that came recently form Ubuntu repository, but no one else seemed to have a similar issue.

Somehow default java that system uses has been changed. It wasn’t sun-java any more. As soon as I ran:

sudo update-alternatives --config java

and choosed sun-java, it started working again.

Perhaps saves some time for someone.

Is that what Orkut meant by “You’ve got extraordinary tools to succeed, use them accordingly”? :P
