comment How secure are passwords with under 20 characters length?
A very long password may not necessarily be written down if it is a set of 5 normal english/your language words. Brains are good at remembering them and there are a lot of them out there.

MD5 passwords use a pretty big salt. I don't think your rainbow tables are going to be big enough to have both all 8 character passwords and all salts for each possible password.

comment Configure a Local DNS Resolver That Only Caches for a Short Period
Okay, I'll accept that you can ignore the ttls and wipe them more often. The (bind9) example solution described by Dave doesn't seem to do only that, though. The dig response includes the ttl amended by the caching server (300) not what's actually published by the authoritative server. Not that it matters, really, but I think it is noteworthy.

comment Configure a Local DNS Resolver That Only Caches for a Short Period
The whole situation is a bit of a hack though, isn't it? I publish a DNS record with a particular TTL, that's the TTL that should be reflected in a cache. It's a bit of a angels on pinheads sort of situation, but which is better, storing a lie (overriding the ttl) or frequently forgetting the truth (wiping the whole cache). Jason Tan's answer really is the best of the lot.

comment Understanding colo pricing with respect to power needs
That 1A number seems pretty low. I measured a rackable with a pair of opteron 250 CPUs and 8gb of ram in it -- under load 2.5A/110v. I took out one of the CPUs (and 4gb of ram) and the power draw went down to 1.2A.

comment Determine Location of Inode Usage
That would likely take a billion years. A quicker thing to do is to run lsof | grep DIR and look in each of those directories for lots of new files.
