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.

apt-dater slides and steps

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.

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)

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.

Integrating Asterisk and behind a firewall

Asterisk is an open source telephone switch (PBX). Although it can be used in complex environments, it can also be deployed for simple home use.

I was planning on Describing the set up and configuration for my Asterisk server, but I found that there are many good tutorials that already cover the general steps. For example, this one from our fellow KWLUGer and Linux trainer extraordinaire rpjday

Hello All
My name is Bill Rieck and I would like to invite you to the first meeting of
the Kitchener-Waterloo Linux Users Group (KWLUG) on Oct. 13, 12-1 PM.

Font sizes in Drupal 5 vs Drupal 6

John sent a message to kwlug-disc arguing that there is no difference in font sizes between the old KWLUG site and the new one. Unfortunately the attachments were too big for the list to accept, so I am publishing the .xcf files here.

Cut-Over Completed

The web site cut over is done. We are now in good standing t perform other changes to the site. We will initially be addressing administrative issues but soon, perhaps, we will work on functionality changes.

Web Site Cut-Over

Thursday evening (around 6 PM) the KWLUG web site will be going into maintenance mode and will be unstable for a couple of hours while the upgrade from Drupal 5 to Drupal 6 is performed.

This is an in-place upgrade so although the site will be initially going into maintenance mode and therefore inaccessible we will need to bring the site back on-line to make final configuration changes and for testing. During that time the site's look and functionality may vary wildly.
