Bootstrapping my Blogs

Ever notice that blogs that are tutorial in nature spend a lot of time providing instructions on installing things, but a whole lot depends on what the author already has installed that he's forgotten to tell you about? Or perhaps the author simply left out the details necessary for you to fully replicate his environment? For me personally, I get downright tired of writing the same thing over and over. Like my code, I want my blogging efforts to be efficient and DRY. Since I work extensively with virtual machines to maintain an orderly environment in a known state, I figured it makes just as much sense to document by establishing a git repository that contains all my bootstrap scripts and configuration scripts needed to get things installed. Whether you use bare metal or virtual machines, you are now empowered… read more


Ruby, Mysql, CentOS 5, and 64-bit

I have lately switched away from Ubuntu as my desktop and started using CentOS 5.2 because I wanted better support for a lot of RAM and virtualization (where I can quickly commission Linux servers to build out my testbed of target environments).  With the change, I also make the leap into pure 64-bit libraries with little to no 32-bit libraries installed.  There's been a few sticky points to push through and one of them is getting Mysql and the appropriate mysql gems installed.  This quick post shows the way. ## My System I am running CentOS 5.2 64-bit. Or more succinctly: ~~~ text 2.6.18-92.1.22.el5 #1 SMP Tue Dec 16 11:57:43 EST 2008 x86_64 x86_64 x86_64 GNU/Linux ~~~ ## The Problem If you simply execute: ~~~ bash sudo gem install mysql ~~~ You'll get the following errors on a 64-bit system:… read more


Jumpstarting your Virtual tour with Oracle VM

Server virtualization technology has come a long ways in the last 18 months (today being a wonderful October 28, 2008 crisp, cold Fall Sunny day).  Here, I am going to take a look at Oracle VM, one of the relative newcomers to the game and show you how to quickly get up and running with a Xen host and virtual server. ### A little background... Our shop has been using virtual technologies for just over two years. At the time we started taking it seriously, the open source offerings were just on the cusp of being production quality; Citrix had not yet bought into Xen; and VMWare had just rolled out their free VMWare Server option.  We had a mixture of Linux and Windows servers, all physical, and were really feeling some of the budget pince in our rapid growth.… read more
