Learning Puppet: Modules & Classes

I am having a good time leaning puppet and have finished up to Modules & Classes for today. One thing we need where I work is a way to insure that PHP is set up consistently and thias/php might do the trick. Checking it out...

USB to RS-232

Today I received my USB to Serial Converter for connecting my laptop to an RS-232 serial device. Cisco has a cheat sheet for using screen to connect to their gear.

Personal OpenStack via Crowbar

Crowbar was made to easily deploy OpenStack. Here are two 10 minute videos showing how to install Crowbar:

and then install OpenStack on top of it.

The narrator, Rob Hirscheld, does it all on one physical box using a couple of VMs.

toy cluster

I built a quick lab at home to learn some new cluster tools. I got four Dell OptiPlex 755s (Intel Core 2 Duo, 3G RAM, 50G disk) named James, Lars, Kirk, and Cliff. They are connected with a Cisco 806. As previously documented I am using minicom to reach the Cisco. My next move is to uplink the Cisco to my WRT54G. Time for a crash course in IOS.

Good old tape?

The need for large storage that can be very slow is becoming clearer at work. If that data must be kept on site then getting 150T usable (in R1-like config) in 5U via a TS3310 is appealing. So is being able to grow to 2.5 PB in a 41U configuration.
