comment Maxing out both PDUs in a rack with redundant power
Random idea: Perhaps you could have 3 power supplies to the rack, then have 1/3rd of your servers connect to each combination of 2 from the 3. In the event of 1 failure, you only add 50% more load to the other circuits, not 100%. So to run 20A of servers, you need 30A of power, not 40A.

comment Gzip Piped to Rsync
@bichonfrise74 gzip is perfectly capable of piping it's output. rsync is not capable of "transferring" it. rsync needs a source file and a destination file and synchronises them, sending only the differences between the two.

comment Setting Up Git Repository on Remote Windows Server?
It's not the ONLY GUI method - there's also gitstack.com (I am not involved in the project & haven't tried it). There also might be others.

comment Log every command executed from root
You can just run sudo su - and have a root shell that won't be logged (except that you started it). This is what I normally type when I want to do more than a single command as root in one go, or if I want tab completion in directories normal users can't read.

comment phpBB: How to handle spammy registrations?
CAPTCHAs are a good idea, but ReCaptcha doesn't seem to be working for us - we're still getting lots of spam registrations.

comment Global DNS provider: DNSMadeEasy vs UltraDNS
Unless I am missing something, opendns.com doesn't seem to provide a hosting service, only a lookup service.

comment Configure routing between same network address
But that doesn't help because both networks have a 192.168.1.10 address that he wants to send traffic between.

comment Convert a CSV file to a XLS file on the linux command line?
In Office 2007, I get a warning "The file you are trying to open is in a different format than specified by the file extension. Verify that the file is not corrupted and from a trusted souce before opening the file. Do you want to open the file now?", which probaly isn't acceptable in many cases.

comment Convert a CSV file to a XLS file on the linux command line?
If a csv saved with a .xls extension doesn't work, you could try a tab separated text file. That's an easy conversion as long as there are no newlines or tabs in the data.

What search string to you type into google to get those answers? What are the advantages / disadvantages of each? This is a completely valid question for this site.

comment When would you use the “password never expires” option?
I really have no understanding of how forcing users to change their passwords is supposed to help. Do users like to reveal their old passwords after a while? I guess it helps if the attacker wants to lie low for a while before launching an attack, but that seems like a small unlikely gain.

comment Graphical MySQL tools
This would be a good answer if it didn't start with the statement "There is no free GUI". If you edit that, I'll upvote you.

comment Any good resources to train helpdesk workers on the basics of avoiding social engineering attacks?
@ErikA: One example story from the Kevin Mitnick book (mentioned in another answer) is a hundred times better than any amount of just telling people not to give out information.

I was kind of hoping for links to articles and stuff, not just random small tips.

comment Specifying Username/Pass as part of a UNC path or map network drives for a windows service
When you say "the above answer should work" which answer are you referring to? This is (currently) the top rated answer, so there is no answer "above" it.

He's not using FTP. He's using Putty, which is an SSH client.

comment Apache: Send pre-packed gzip'ed files
Why the ! before gzip on the Accept-Encoding line? Surely that's the opposite of what you need?

comment Apache: Send pre-packed gzip'ed files
This isn't a huge problem, but reading that config, if someone manually fetched the .css.gz file, they would get the text/css, when they should get the application/x-gzip type.

comment Apache: Send pre-packed gzip'ed files
I'm amazed this isn't way more obvious, as it seems crazy to have a web server that doesn't do this. I think IIS has a system to cache gzipped copies of static files on first access. mod_deflate doesn't mention such a feature.
