TKLPatch summer contest summary: let the judging begin!

It all started with a happy accident

I have a confession to make. This contest, which is directly fueling the largest expansion of the TurnKey library since the project started, is a happy accident. It wasn't something we planned. It wasn't on our summer todo list. It was just one of those unexpected, spontaneous ideas that light up the inside of your brain like a flash bulb, and demand you take action. Or else! (you won't get any sleep)

Back in June we had just launched the TurnKey Hub and were getting ready to focus all our energies on releasing TKLBAM. I logged into PayPal and noticed our donated beer budget had a sad little beer belly. It was just sitting there, giving me an accusing look. I felt guilty. Surely all those people who donated expected we would put these funds to better use. That's when it hit me. It was too much to buy beer, but not so much that we couldn't risk it all on a fun experiment...

I talked it over with Alon and on an impulse we decided to do a contest, but not just any contest. A wild and wet summer open source bonanza! With ponies!

What happened next took us both by surprise.

LXDE review: it zips, it flies! (base for client-side TurnKey appliances?)

At home we canceled our cable subscription a few months ago. We hardly ever used it any more. Instead we were downloading content to a makeshift media server and watching it on our own schedule. Many of the shows I like (e.g., Colbert Report) aren't even available over here.

Upstairs we had a gorgeous big screen HDTV set that was being powered by one of my old computers, a nice P4 machine with 1GB of memory that was running the TurnKey Torrent Server appliance on bare metal.

Background: how a backup key works

In TKLBAM the backup key is a secret encrypted with a passphrase which is uploaded to the Hub.  Decrypting the backup key yields the secret which is passed on to duplicity (and eventually to GnuPG) to be used as the symmetric key with which backup volumes are encrypted on backup and decrypted on restore.

TKLBAM: a new kind of smart backup/restore system that just works

Drum roll please...

Today, I'm proud to officially unveil TKLBAM (AKA TurnKey Linux Backup and Migration): the easiest, most powerful system-level backup anyone has ever seen. Skeptical? I would be too. But if you read all the way through you'll see I'm not exaggerating and I have the screencast to prove it. Aha!
