Names Matter -- DRM and the Press
While reading the comments at the Digitial
Rights Pledge page I noticed one by D Walker: "Digital Rights"
would too easily be muddled up with "Digital Rights Management", which in
itself should be called "Digital Restrictions Management". It's an
ever so small point but I think it's important; Digital Restrictions
Management is a much better name than "Digital Rights Management". It
pushes the point that it's taking things away from us and is a lot less
media friendly...

Fantastic Four -- Quickie Review
Over the last couple of years comic book fans have been spoiled by some
great big-screen adaptations. Spiderman 1 and 2 (which NEED more witty
one-liners from the wall crawler), X-Men 2, HellBoy and Sin City have all
been enjoyable and lived up to the franchises that spawned them. We've also
been witness to some truly dire moments, Catwomen and Electra spring to
mind. So where does Fantastic Four fit?
It's pretty average. Michael Chiklis does a good job as The Thing (although the suit looks dire; that needs to change for the sequel), Ioan Gruffudd is pretty bland, Chris Evans character is badly written and never fleshed out (possibly on purpose but it just gets annoying) so we'll discount him and Jessica Alba... well she looks damn good with blond hair and wearing a cat-suit but the role didn't exactly seem challenging. She was better in Sin City and she had a lot less screen time in that.
While it's not a disaster it's not something you should bother travelling to see. One to rent cheap. 4/10.

Using sudo Without A Password
If you add a NOPASSWD directive in your sudoers file then you can,
as you'd expect from its name, use those commands without a password.
This is a pretty useful trick that allows you to set up sudo entries
that allow commands to be run with different privileges from cron
without requiring the setuid flag. However twice this week I've seen a
similar question asked on mailing lists and I thought I'd stick this
entry up, hope google indexes it and saves me from ever seeing it again.
Yeah right.
When you use sudo and authenticate it sets a short timeout period in which if you use sudo again it won't ask for your password. This is typically a useful feature (for interactive use anyway) but a couple of people seem to follow a series of events that go something like this: sudo visudo (add the NOPASSWD line). sudo "command I want in cron." "Oh look, it worked. Now let me add a cronjob." The next day they (hopefully) notice it didn't work and then ask on a mailing list. Which I'm on.
Now it seems obvious but people don't seem to realise that the trial run is pointless, the timestamp is still valid from when they ran sudo visudo and so sudo WILL NOT PROMPT FOR THE PASSWORD. In order to run a real test you need to use sudo -k to invalidate the timestamp and then rerun the command.
As a closing note adding a sudo -k to your .logout/.bash_logout file can also be a smart thing to do on some systems.
