comment Does enabling hardware x86 virtualization (AMD-V or Intel VT-x) slow down my computer if I'm not running virtual machines?
VT-x and VT-d are just extra instructions in your CPU. Not using them has the same exact impact as not using any other instructions--none ;)

comment bridge in linux
Out of the man page: "brctl setfd <bridge> <time> sets the bridge’s ’bridge forward delay’ to <time> seconds." by default it's 30 seconds, so I'm guessing that's what you're experiencing. Set it to 0 right after you bring up the bridge interface.

comment Disable HTTP Methods in Apache
Mod_rewrite also runs slow regex on every URL process, which slows the server down. Use with caution.

comment Apache Virtual Host by name
The general answer is yes, but there are some sub-cases. Which type of vhosting are you trying to do? IP, port, name, or mass name-based vhosting?

Try changing the hashing algorithm to SHA1 or MD5, see if that fixes it.

comment What does 'set -e' do, and why might it be considered dangerous?
What this reminded me of is a C++ prof of mine that was always pulling points from my assignments for not having single entry point/single exit point in a program. I thought it was a purely a 'principle' thing, but this set -e business definitely demos how and why things can completely spin out of control. Ultimately programs are about control and determinism, and with premature termination you give up both.

What kind of changes? Content of files, or just changes in the metadata, like permissions or ownership?
