Actually... I've had the kde screensaver crash on me at some point which effectively unlocked my machine.

Also, I've seen notifications come through the lock which allowed you to task-switch out of the lock. I believe I once had this on OS X lion as well, although it could have been an earlier version.

It could still be a great device if they'd simply fix the software

The bluetooth transfer idea is quite useful assuming it's used in a smart way. Having a screen where you can see your latest mails, messages, stock info, etc... all the time even in the bright sun could be useful.

Especially if it works for a much longer time than your phone will. I still see potential, but I have a lot of doubt that they'll use it.

100 byte chunks would work just as well, but with a smart raid card and 2GB raid cache the difference in execution time is fairly low actually. When creating this I did try 1k blocks first and it didn't have any noticable (i.e. wall clock) slowdowns in the long run and did give me a few false positives.

YMMV though, for my use case this was useful. For you that might be different

Indeed, I once created a dedup script which basically did that.

1. compare the file sizes
2. compare the first 1MB of the file
3. compare the last 1MB of the file
4. compare the middle 1MB in the file

It's not a 100% foolproof solution but it was more than enough for my use case at that time and much faster than getting checksums.

Unfortunately Ghostery and/or Adblock are not always an option.

My bank (ABN-AMRO) has recently updated their website and with that added Omniture tracking to all pages. If you use Ghostery (as I do) the site just stops functioning entirely and the entire Internet banking system doesn't work anymore.

So unless I permit Omniture to see everything what I am doing and effectively giving them access to my bank account including transferring money to other accounts... I cannot access my Internet banking system anymore.

BIG FAIL from the ABN-AMRO in my book. If you're going to use tracking/analytics software like this, make sure your website keeps working if it's not available...
