The Great Server Room Flood of 2010

OK that title is a little dramatic but it could have been bad.  Here is what happened.  I had to go in to work this morning to upgrade a customer’s servers remotely and managed to leave my phone at work.  After I took my kid to swim lessons I went back in to work to get my phone.  I decided to show my kid the server room, which turned out to be a good idea, because when I opened the door I saw, to my surprise, a puddle of water on the floor.  I looked up and saw a ceiling title that was completely saturated with water.  I ran around the office grabbing as many trash cans as possible because I didn’t l know what would happen once I knocked the ceiling tile out of the ceiling.  Luckily the water that was dripping down from the ceiling was about 6 inches from a server rack and not on top of it.

After knocking down the tile, which basically crumbled when I touched it, I was able confirmed the source of the water.  Over the servers is the air conditioner.  Below the the air conditioner is a drip pan that is about 5 ft long 2.5 ft wide and about 2 inches thick.  I grabbed a step stool and stuck my hand in this drip pan.  It was completely filled with water.

I knew that I had to drain this water but I was unsure exactly how.  So I ran over to the tool box and grabbed the drill and a the biggest bit I could find.  I knew that if I waited much longer that drip pan was going to start to over flow in more areas then just the one corner that wasn’t over the servers.  Once again I ran around the office this time I grabbed the 14 gallon tubs that we use as paper recycle bins.  I get on the step ladder and start drilling the hole.  As excepted, the water started to rush out.

Forty-five minutes later the drip pan is finally empty and one 14 gallon tub is full.  I found that the water is coming from the air conditioner’s relief pipe. What I don’t know is why it is dripping as much water as it is. I guess I will find out Monday morning when the HVAC people.

Here are the pictures that I took with my iPhone.  Sorry the the quality is kinda bad but I was in a hurry to get the water cleaned up.

Update (2010/04/27):
The fine HVAC folks at Newcomb came out and determined that the issues was a clogged drip pipe.

Digital Photocopiers Loaded With Secrets

Nearly every digital copier built since 2002 contains a hard drive – like the one on your personal computer – storing an image of every document copied, scanned, or emailed by the machine

Scary!  More.

Google Code University

Have you ever wanted to learn how to program?  Ever wanted to learn how program for free?  Have you ever wanted to learn how to program from worlds largest on-line search provider?  Well now you can!

Google Code University is a free site that has on-line courses to teach you how to  program in many different programing languages.  It include on-line video lectures, written material, and code examples.  Currently I am taking the Python class so I am sure you will see some Python projects on this site soon.

60% of Americans engaging in couch potato multitasking

That translates to about 3.5 hours of overlapping TV/Internet time per month for the average American consumer, according to Nielsen’s data from the fourth quarter of 2009. Nearly 59 percent of consumers reported doing this at least once a month as well, up from 57.5 percent in 2008. That’s a lot of people spreading their attention across multiple screens, which is why so many shows are beginning to advertise live online polls, chats, and more during the course of broadcast. People aren’t just hitting up those websites after the show is over—they’re hitting them up as the show is going on.

Glad to see that I am not the only one.

Fix Minimize/Maximize/Close Button Order in Ubuntu 10.04 Lucid Lynx

For some unknown reason the developers of Ubuntu 10.04 Lucid Lynx swapped the order of the minimize and maximize buttons.  Here is how to change it back to normal order.

In Gnome hit Alt-F2 to open up the run box.  Once opened type gconf-editor

Once gconf-editor is open navigate to the apps -> metacity -> general and change
button_layout to :minimize,maximize,close

That’s it.
Update: (2010-05-12)

Even easier way and cooler because its done on the command line is to open up a terminal and while logged in as your user account

Type this:

gconftool-2 --type string --set /apps/metacity/general/button_layout ":minimize,maximize,close"

Update: Thanks to the comment from LMB you can use this command to add the menu icon on the left side of the menu bar.

gconftool-2 --type string --set /apps/metacity/general/button_layout "menu:minimize,maximize,close"

A picture is worth more than a 1000 words

A picture is worth a thousand words. Well, actually, if it’s a VGA picture with 24bit color depth, then it’s 640x480x24bits = 7,372,800 bits = 921,600 bytes. If each byte is one character, assuming an average word length of 8 (with a space after each word), we get about 115,200 words. So our ancestors were off by two orders of magnitude. Maybe they were assuming 200×150 images? Whatever
