comment Odd POTS fax issue
When you say they're on the same line, what do you mean? A POTS line can only have one phone call at a time. Do you mean one telephone number? If you actually mean one line, then of course multiple things attempting to dial on the same line are going to break.

comment Can 3G networks be packet sniffed / analyzed?
$5mil is way more than it'd take, real number is probably several thousand, at most. Many of the ciphers used have been broken; the chipsets to receive cell signals are very cheap; etc.

comment portable unix way to join strings with separator
Considering OP wants to join parameters, that'd be perl -E 'say join(shift, @ARGV)' -- delim str1 str2 str3 ... The perl one-liner you've posted doesn't actually do anything (well, it changes $_, but that isn't passed into or out of the one liner). You probably wanted to pass -p as well.

comment Fastest/scalable way to serve static files?
Buffer-cache automatically uses RAM that is otherwise free. To increase it, add more RAM or reduce RAM usage by other things, but I'm not convinced that's really your bottleneck. Once this gets moved to Serverfault, it'll be seen by a crowd that more routinely deals with this stuff.

comment Fastest/scalable way to serve static files?
This is a question for Serverfault. BTW: Its surprising you're seeing performance bottlenecks serving static files (are you really? and why is it reading from the hard disk each time, have you disabled the buffer cache?)

comment Bind9 Ubuntu and Google DNS
504 errors come from your web server, not your DNS server. But this belongs on Serverfault.

comment introduce latency between ec2 instances
This probably belongs on Serverfault, but the normal way on Linux would be with the network emulator queuing discipline. linuxfoundation.org/collaborate/workgroups/networking/netem

Quite possible. Soon I hope to pull that machine, and do extensive testing on it.

comment Making SATA disk write cache safe
Ummm, these are Seagate Constellation ES drives. The other server (the one with the 3ware card) has VeliciRaptor drives. No cheap desktop drives in sight. Though, honestly, I've got other machines with cheap desktop drives, they've proved only a little less reliable.

comment Making SATA disk write cache safe
Yeah. I have a 3ware one on a different box. The data is indeed safe, in the sense that had Sony bought some of those, PSN data would be safe from crackers. Every time a single drive timed out, it'd discard cache on all drives, leading to massive corruption. I turned off the cache.

ST3500514NS are most definitely not SSDs. But that is interesting.
