The Raspberry Pi revitalized my inner geek

As a single guy (AKA geek) just out of school, I tried to keep up on all the cool and upcoming tech. Over the past 15 years, I got married, had a kid, had several different roles at work and pursued a few different hobbies which steered me away from a lot of the fun I used to have with technology. I kept up enough to be proficient at work and to be the go-to tech guy of friends and family but I didn't have the drive or time to experiment as much.

Video editing using ffmpeg and ImageMagick

Sometimes, you want to edit multiple videos in a similar way. For that, I've found that the best way is to create a script that you can run consistently on those videos and get a consistent ouptut. For example, recordings from a conference or a day by day video log of your family vacation.

I have created some scripts using ffmpeg and ImageMagick for my some of my videos, saving me hours in the process.

The main advantages I've found are:

  • Consistency: I don't have to remember what I did to a video. It is all in the script

Linux literacy course

(Apologies to those who have seen me plug this for the 15th time)

I am involved with running a course on "Linux and Free Software Literacy". The course starts at 7pm on Tuesday, October 18. It will be held in downtown Kitchener.

If you are interested in participating, there is still room in the course. Visit the KW FreeSkool site for more information.

Here are the slides from the July 2011 presentation on keeping Ubuntu/Debian systems up to date. The zipfile has some sources.

Installing LAMP on Ubuntu 11.04 aka The Natty Narwhal

As new user with Linux using Ubuntu 11.04 I was in the "now what?" moment.
Then I recalled Khalid's presentation on LAMP.
Exploring with the Google I found the following tutorials.

http://tuxtweaks.com/2010/01/how-to-uninstall-lamp-in-ubuntu-9-10-karmic-koala/
http://tuxtweaks.com/2009/07/how-to-configure-apache-linux/

There were tuts going back a few revs but I thought 10.04 tut was close enough to 11.04.
And! Success! I now have a Linux webserver running LAMP.

Using an Android Phone as an Asterisk extension

Think about using your Android phone, connected through 3G or through WiFi as a telephone extension.

What do you need?

  • An Asterisk server (can be set up very easily)
  • A DID (VoIP phone line which usually costs very little)
  • An Android phone (or multiple phones)

Why?
Of course, Android is a phone, but using the cellular network costs money. If you configure your smart phone to register to Asterisk, the calls to your home/office are free and the calls to other numbers cost the same as if you were calling from the home/office.
