Short one today – I was looking for a way of converting all my ripped CDs to an alternative format for portable audio use.

Here’s a useful link for doing scripted, recursive audio format conversion.

Now you can rip all those CDs to FLAC format (which is lossless, unlike lossy mp3CBR or VBR) and then convert the lot to mp3 for the iPod, car, etc.

Oh, and a copy of Fedora or Ubuntu would probably be handy too 😉

Of course, you could pay for a commercial alternative or even – heaven forbid – “upgrade” your iTunes for DRM-de-restricted AAC files (which are still lossy-format files anyway).

So, why bother, when a CD costs the same and has better sound quality?

Forget digital downloads, until they respect your freedom.  Buy CDs!!

Or, if you are 100% sure your data will always be safe and/or don’t have a hi-fi CD player (in addition to CD/DVD-ROM drive) to justify getting physical media, investigate these forward-looking alternatives:

 Enjoy!

I recently found myself having the need to revoke an old certificate. The steps are actually quite straightforward, but you do need to have your old revocation certificate to hand.

Simple follow these steps. In a terminal, issue:

  • gpg –import my-old-key@mydomain.com (0x712AC328) rev.asc
  • gpg –keyserver certserver.pgp.com –send-key 712AC328

That’s it!
