I've handled this exact same issue. I work for a property management company and have wall-mounted half-racks with big, 4U Bosch DVR's at quite a few facilities. (These are basically rack-mounted mid-tower PCs with a steel front panel and a mobo that accepts the camera feeds.) We use a garden variety wall cab which consists of a huge, huge wall bracket with the cabinet attached on a hinge for rear access.

Weight concerns? These DVRs weigh a TON; about the same as a 4U server stacked with hard drives. It's a bit of a snug fit in the back, but they've been mounted and running for years.

That being said, you most definitely can mount servers in a wallmount cab, depending on their form factor. Specifically, you're pretty much limited to mid tower servers that can be converted to rackmount. You most definitely cannot mount most servers advertised as 'rackmount' due their tendency to have a lot of depth. (Unless you're talking about SuperMicro or something.) An HP DL180, for example, will need around 6-10 inches more depth than any wall-mounted cab can provide.

So there you go.

Unless you have the foresight to use a spoofer or - even better - use a throw-away USB wi-fi dongle, your MAC address will show up in the router's DHCP client log until the lease expires. Boom, headshot.

Some colleges are becoming more cognizant of the fact that not everyone who works in computers is necessarily a full-time programmer.

My college started offering a 'Network & Information Systems' major the year that I started. Basically a big fat injection of Unix-like operating systems, NOC engineering, databases, and even a big chunk of programming thrown into the mix. No Calculus. Other colleges are pursuing this trend as well.

Anectodally, I'd say there absolutely is a difference. I completed college in 2008, intensely aware of that fact that although I took courses in FreeBSD, mySQL and such that I would get eaten alive by anyone who works professionally in Unix-like OSes and databases. I'm surprised to hear business students feel differently about their field of study.

The solution in my case was to be vocal about how little I know - though I do know a lot- and my desire to yield to and learn from people with experience.

Leave certifications to CPR and Scuba Divers.
Let's not forget that vendor certification is a spectacularly profitable source of income. A 2-3 day vendor boot camp is comparable in cost to weeks of lectures, labs and homework assignments of a college course. That is of course fine, it is your money to spend. Where I take issue is where individuals start appending certifications to their Outlook and forum signatures like it's a goddamn PhD. I've shown MCSA's how to change the BIOS boot order and CCNA's how to burn a CD.

To me, certifications in how they apply to the individual shows that the rote memorization is there, but the passion is not.

My MBP has a miserable battery life running Ubuntu.

W.... what? Boston may be "full of itself" in regards to sports, but I had landed a sysadmin job before I even graduated late last year, after only a month of job searching. Even my brother landed a sysadmin job a week after being laid off. If you're intelligent enough to compete with the many local tech school grads and like working in IT, Boston is where you want to go.

And before you complain about real estate prices there, do bear in mind that you don't have to suffer through tornadoes, floods, earthquakes, and the last major hurricane we had was a gust of wind compared to what Floridians routinely deal with.

Clearly you've never been to Boston. Red Sox fans are just drunks, but for the most part relatively harmless.
Meanwhile, you can't put on a Sox hat and walk three blocks in NYC without being accosted. I know from firsthand experience; last time I was in NYC, a complete stranger bloodied my nose in front of the Roosevelt, screaming "Go back to Boston." So I did!

And now he has a brain tumor the size of a nectarine. Karma's a bitch.

But they make sure to ship it with a Vista sticker anyway, just to make it that much more of an annoyance when you want to wipe the crapware-laden drive and build a ghost image from scratch.

Man I hate OEMs
