comment Howto expand all columns in Excel spreadsheet?
Just a comment: "howto" as one word usually means "this is a guide" not "how do I".

comment How to change the default location for the standard File Save dialog in Mac OS X?
Most apps remember the folder that either: 1. Was last accessed by the system's file dialog; or 2. Was last accessed by that application.

comment Cannot delete podcast from iPod Touch
I'm not clear on something: how are you attempting to play it if you can't see it anywhere on the iPod or in iTunes? Where are you playing it from?

comment Control iSight indicator light on MacBook Pro
I've been looking for a kext or other tool that would light the camera lamp while the microphone was listening, too. If you ever come up with something like that, let me know :)

comment How to backup Servers to an SSH-Host with low traffic and access to versions and encryption?
Quite right, but a good number of people don't realize this either: an acceptable definition of a perfectly-encrypted stream is that it is indistinguishable from a random stream (hence the need for a random entropy pool for encryption).

comment What is the difference between safety and security?
This sounds most suspiciously like a first-year university CS assignment question… (I don't mean to be rude if it's genuine.)

comment Safe to use high port numbers? (re: obscuring web services)
@wag2639 You're not really doing anything by changing a service's port number but making a script-kiddie find a slightly better script. War-dialing a block of IPs and ALSO portscanning every single port is trivial.

comment Safe to use high port numbers? (re: obscuring web services)
No it's not true. Modern (even desktop) multi-core CPU machines with broadband access can scan all 65535 ports in seconds. And even if the attacker decided to space them out to two a second to foil a DoS gates, who cares, you're leaving your system up for more than a day, right? An old maxim is, as others have said below, that "security through obscurity" is essentially useless in the digital world.

comment Intercept email and see its content
I presume that attempting to circumvent your monitoring policy is itself a violation of the policy? They'll eventually catch you. "Hey, so why does this guy have 2 gigs of ssh data in and out every hour?"

+1 "if they're that paranoid about spying on you, then they'd simply block all encrypted connections anyway"

comment How to speed up rsync?
rsync is so called because it's for remote synchronization and is not really appropriate for a locally-connected volume for this very reason.

comment Running cat5 cable outdoors
@Keck +1 for conduit. All wires are waterproof because they're sheathed in rubber, but you'll (hopefully) never see your telco or municipality running bare wires underground.

Except doing things like silently installing the .NET Framework as an add-on in Firefox through Windows update? ;)

comment Mac OS X: Best Way to Make an ISO from a CD or DVD
Now that I think about it, the solution I cited below with hdutil is somewhat simpler, as you can use the literal path without having to know the /dev assignment of the device, which is useful if you want to reuse this for only a folder, or an external hard drive, or multiple optical devices.

Way to beat me to it ;) This is the most elegant, lowest-overhead solution. See my others below.
