comment Is there some difference between mv and {cp + rm the old file} on Unix?
Also mv never changes permission or ownership. Imagine you want to move a file from your buddy's homedir to your own homedir. If you mv it you will end up with a file in your homedir that belongs to your buddy. You can't chown or chmod and depending on the permissions not even modify or read it. If you do cp followed by rm the file will belong to you and everything is fine.

comment Ubuntu: Should I backup the entire home directory?
In addition to the firefox profile I exclude ~/UbuntuOne (because it is in the cloud anyway) and large caches like the trackerd cache and ~/.googleearth/cache. This saves a lot of space.

comment What's behind the Linux disk naming convention with sdX and hdX?
Everything that is addressed through the SCSI subsystem is usually sd*. That is why SATA drives show up as sd*.

comment Best SIP VOIP hardware ever. Suggestions?
It's possible to turn off the modem with many models. Probably all except very old ones. Yes, plugs and voltage in Germany are the same as in Portugal.

@Nippysaurus: I'd tried it with menutrans in .gvimrc. Didn't get it to work, will have another look at it in the evening...

comment How secure is it to use a password hash of a common English word as a WPA2 key?
I mostly agree, except for that a hash of an english word is not a random string of text. It is what it is, a hash of an English word. In other words: The proposed method doesn't enlarge key space, but it does render widespread rainbow tables useless. Given the fact that generating a rainbow table is not that easy, this is a good thing. To enlarge key space you might consider encrypting your password with a salt.

comment Best tool for writing a Programming Book?
@Idigas: I think it is more because the question is like: Best Tool for hammering a nail into the wall - my screwdriver breaks 10 times a day and a hammer is out of question.

comment Best tool for writing a Programming Book?
The only reason TeX was conceived was to write a programming book. "The Art of Computer Programming" has more than 1000 pages. If (La)TeX is not suitable to write a programming book I wonder what else is:-)
