  Ubuntu 12.04 LTS, LVM, KVM, and Fun SysAdmin | (0)

  Occasionally my job affords me the opportunity to do some really cool stuff. For a myriad of reasons I am building myself a Linux KVM host using Ubuntu 12.04 LTS. I hurried through the install prompts and didn't pay enough attention to the partitioning. Therefore I ended up with 96GB of swap space and a 40GB root partition. My goal was to have no swap, a small root, and a large partition for the KVM guests. I disabled swap and destroyed the swap LVM partition.  I then rebooted into the always handy Rescue Is Possible (RIP) using PXE and resized the root ...

  I am running for a position on the Board of Directors for LOPSA SysAdmin | (0)

  I am running for a position on the Board of Directors for the League of Professional System Administrators. I just posted my Candidate Statement on the LOPSA site @ https://lopsa.org/content/2012-candidate-statement-martin-gehrke . Here it is in its entirety: My name is Martin Gehrke, and I am running for the LOPSA board. Why am I qualified to be on the Board? While I am relatively new to LOPSA, I feel I have a lot to add. When learning that Pittsburgh did not have a LOPSA chapter, I founded one. We have grown from nothing to meetings of 10+ members. I have also been a leader ...

  Sysadmin Resources SysAdmin | (0)

  There are some great sysadmin resources spread across the internet, but it can be difficult to find them in the morass. Here are some I have recently stumbled across.

  Webcast Review: Conducting a Technical Interview by Elecia White SysAdmin | (0)

  I have recently been doing an increasing number of phone interviews. I want to make sure we bring in the best candidates while saving my colleagues time by screening out candidates who can't make the grade. Click through to see a review I did of a webcast from O'Reilly.com. This review was originally posted at SNAPGH | System and Network Administrators of Pittsburgh. Here it is posted in its entirety.

  More Cooling Fun SysAdmin | (0)

  What is a BTU? BTU which stands for British Thermal Unit is just another example of the British trying to confuse everyone. While the metric system has gained a stronghold in science and engineering, it seems like heating and cooling are stalwarts against the tide of the metric system. The British thermal unit (symbol BTU or Btu) is a traditional unit of energy equal to about 1,055 joules. It is approximately the amount of energy needed to heat 1 pound (0.454 kg) of water (i.e. exactly one tenth of a UK gallon, or around 0.1198 US gallons) from 39 to 40 ° F (3.8 to 4.4° C).[wikipedia] Latent vs Sensible & Dry ...

  Heating & Cooling Formulae SysAdmin | (0)

  A friend of mine was getting his A/C units service at this data center and the service tech was nice and handed us date books, thanking us for the business. While I never use a date book, there was something very useful inside: a page containing heating and cooling constants and formulae.

  The Limoncelli Test: 32 Questions for Your Sysadmin Team SysAdmin | (0)

  This is a very boiled down version of The Practice of System and Network Administration. "People often ask me how they can improve their sysadmin team. It takes only a brief discussion to find fundamental gaps that, when filled, will improve the teams's productivity and the quality of the service being provided. Such a gap doesn't just create many problems, it creates many categories of problems.

  Home Sysadmin Projects Computers, SysAdmin | (0)

  One of the easiest easy ways to show your chops as a Sysadmin is to mess around at home. I have known a couple Sysadmins who always asked about an interviewee's home setup. I have read a couple of articles about how the new programmer's resume is GitHub or their commits to open source projects. This is the Sysadmin version.  The following are a couple of current projects of different sizes that one can do at home and give you something to talk about during your interview. They are all relatively easy, my intention is not to give you something ...
