This Week I Learned [19 May 2013 Edition]

This week I learned about:

• There is a new change to how network devices are named. This may change your network device from eth0 to something like env10p0. https://www.freedesktop.org/wiki/Software/systemd/PredictableNetworkInterfaceNames

• Archlinux is very similar to Gentoo, but it is based on a script to install everything.

• 2to3 is a python script that will convert a python script from a version Python 2.0 to a 3.0 compatible script.

  • One major difference between 2 and 3 is that the print statement became a function, thus requiring parenthesis.

• It is easier to hard code the Python 2 environment, rather than to convert the script into a Python 3.0 script.

  • #!/usr/bin/env python2.7 [or whatever Python 2 environment that is installed] should be used in the shell definition of the script.

• OpenVAS- Open Vulnerability Scanner: I haven’t tried this yet, but this is a neat utility that can help you keep tabs on the software you currently have installed and the possible vulnerabilities that they may have.

• Always snapshot your VM after you finish major installs. [This saved my butt this week]

• Ansible -  This looks like a nice Open Source version of HP Operations Orchestration.
