How-To: Create Screencasts on (nearly) Any Operating System

Screencasts, or capturing a digital video of movement on your computer screen, are a great way to create tutorials, presentations, and even entertaining videos. Software used to create screencasts abounds for (nearly) every operating system, and ranges in price from free to upwards of $50.

As an example, here is a sample screencast (2.5 MB – Ogg Theora) showing the installation of Google Desktop for Linux. If you can’t open the video, please use VLC.

Naturally, I prefer the free options, but will give credit when credit is due if a paid option is simply better than a free option. That said, here is an overview of some of the screencast options available for Windows, Linux, and OS X, and possibly other operating systems.

Windows

Option 1: Wink

Price: FREE

Wink is a free screencasting program aimed at creating tutorials. As such, it offers a plethora of options in addition to simply recording the action on the screen. Some of the options include audio recording, inclusion of navigation buttons, adding text, and exporting to various formats, such as PDF, HTLF, and SWF. Wink also allows you to capture still screenshots, including the ability to capture screenshots based on the mouse and keyboard input.

If you simply want to record the action on your screen, choose the designated section on your screen and press SHIFT + PAUSE to start/stop recording. When finished, you can render your video as a Flash movie. Continue reading How-To: Create Screencasts on (nearly) Any Operating System

“Ghost” Your Windows System for Free Using Open-Source Tools

The following tutorial is intended for those with some knowledge of Linux and the command line. At the least, you should be comfortable with creating and navigating directories, and should possess a fundamental knowledge of hardware device names under Linux.

Sound scary? A “point-and-click” guide to accomplishing most of the same tasks is also available.

The Problem

Like it or not, Windows needs to be reinstalled occasionally. Whether the cause is a bloated registry, a virus/spyware attack, or an idiotic user, with time Windows just seems to slow down and/or behave erratically.

Re-installing Windows from scratch is a pain. Once you get the base system installed, most people have to download millions of updates and patches, scour the web in search of the latest drivers, and reboot, reboot, reboot.

The Solution

Once you get your Windows system installed and configured the way YOU want it, you should be able to restore to that pristine state in a matter of minutes, not hours. The way to do this is to create an “image” of your freshly-installed system, from which you can later restore when necessary. Of course, there are a number of commercial packages available to do this task, but what if you do not want to spend any money?

Linux and open-source software to the rescue. Yes, you can quickly, and (dare I say) easily image and restore a Windows system using open-source tools. Before we begin, please back up any critical data. This procedure worked for me, but I am not responsible for any data loss.

The Main Tools

Repeat after me: “I am NOT afraid of the Command Line!”

The open-source tools that we are going to use are:

  • ntfs-3g – a driver for NTFS
  • GParted – a partition editor
  • ntfsclone – exactly what it sounds like
  • a Linux “live” CD

In order to restore Windows, you need to run from a different working environment, such as a Linux “live” CD. Any Linux “live” CD with the above tools will work, but two available options are SystemRescueCD and Puppy Linux. Both allow you to boot and run entirely in RAM, freeing your CD/DVD burner for any additional tasks that you might need. I successfully completed all of the tasks detailed below using both Puppy and SystemRescueCD. Just grab the latest version of whichever you prefer.puppy-logo.gif

Note: If you use SystemRescueCD, I recommend typing docache doeject at the boot prompt. These two options will load the entire rescue environment into RAM and then eject the CD afterwards. Puppy Linux, on the other hand, loads into RAM by default. The rest of this tutorial will use Puppy Linux, though the commands can easily be issued from any live CD that contains the above tools.

Before you can image and restore your system, you need to consider a few things: Continue reading “Ghost” Your Windows System for Free Using Open-Source Tools
