I'm operations manager for Anchor Systems, where I plan strategy, help sysadmins be better at what they do, and occasionally pull all-nighters to build random tools to solve emergency problems. I've been a specialist Linux sysadmin for over 10 years, mostly in the large-scale hosting industry, working for companies like Solutions First and Engine Yard.

I was the sixth user to get to 10k rep on serverfault, and the second to reach 20k. I stopped keeping track after that. Third (by a mere 14 hours) to get the "Epic" badge.

comment CentOS vs. Ubuntu
The question I was asking for help with wasn't simple, obvious, or self-explanatory -- and it turned out to be a security bug in Apache, which Redhat weren't particularly interested in patching, even when I provided them that patch, let alone investigating independently. If I've got to find and fix my own bugs, and then run my own locally-patched packages, what value are RedHat providing, exactly?

comment how to generate a random MAC address from the Linux command line
There's no need to run urandom output through md5sum; you can just use od as per Aaron Toponce's answer.

If you're running hundreds of servers each hosting tens of virtual machines all on the same broadcast domain, you've got bigger problems than MAC address collision risk.

comment Apache server overloaded at 30 requests/second, normal?
There was a point in there? Other than you don't know squat about how to provide proper customer service, perhaps. If a customer doesn't understand what you're saying, that's your problem, not the customer's.

You're on. I'll even give you odds of 2-to-1: I'll pay you 180% if you're right!

No, I'm saying the ISP is incompetent because they don't communicate with their customer sufficiently such that the customer needed to listen to me, instead of the ISP. If the ISP was competent, they'd be able to explain to the customer that the reason the server is failing to cope with the load is because of $VALID_REASON, and invite the customer to upgrade or take some other action to alleviate the problem. That the user had to resort to asking a question here speaks volumes to the provider's inability to service customer request in a competent manner.

If the ISP can't explain the situation to the customer vis a vis needing to pay for a bigger share, then yeah, you can assume incompetence (in sales ability, if nothing else...).
