If you've not heard of Diaspora I recommend you check it out.

Today I was playing with SSL statistics with which is a list of publicly hosted Diaspora pods. After viewing their source I found that I could knock against their API to pull domain names. This was more for a personal scripting exercise than anything. I'm sharing the results with you, the reader.

Getting secure host names

I basically ran python code like the following......

man page keyboard shortcuts

Posted 02-24-2013 at 09:30 AM by sag47

Here's a short list of keyboard shortcuts for reading man pages that I've learned by usage. I've not found a good place shortcuts are documented; man page or otherwise.

man bash
Use SHIFT+G to scroll to bottom of the page and look at FILES. You'll also learn more about how bash loads the bashrc if you read the INVOCATION section of the bash man page.

Helpful shortcuts for man pages...
  • k and j go up and down one line.
  • Ctrl+u and Ctrl+d go up and down half

The content outlined here also works for OpenOffice. This post was inspired by a question I was answering on the forums.

I installed LibreOffice packages using a PPA in Kubuntu. Here is information about my environment.

Using a script to get your IP address

Posted 01-07-2013 at 12:33 PM by sag47

A friend of mine was complaining today how their work place doesn't parse the IP address from ifconfig but asks for manual input from the user. This is the dumbest thing ever. In case you're ever encountered by this here's a horrible one liner to get the job done quick and dirty.

Also, you may need to replace eth2 with your correct interface (such as eth1).
ifconfig | sed -ne '/^eth2/,/^\s\+Interrupt/p' | awk '$0 ~ /inet addr/ { print $2 }' | cut -d: -f2

Better filtered mail notifications

Posted 10-31-2012 at 10:18 AM by sag47

Note: this post is not about mail filtering but about getting better notified on mail that is already filtered. I will assume you have an understanding of bash scripting and how grep works. This includes modifying paths within scripts for your own environment. This is one of those hack together one job scripts.
