Today's Linux screen capture technology

Post date: April 12, 2005, 18:04 Category: Miscellaneous Views: 2478 Comments
Tutorial quote: "I'd like you to help me find out about video screen captures," said one of my editors a while back. "Sure, let me see what's available," I replied. He pointed me to a couple of Web sites to get me started, and here I am a few weeks later ready to share my findings. I'll discuss ways that you can make video clips in Linux, talk about their applications and shortcomings. I'll also cover suitable ways to view your masterpieces once they're recorded.

Video screen captures are useful for jobs like application training, computer instruction, or product demos. An example would be the little one-minute video I set up for my wife. She kept forgetting how to start up Mozilla Mail on her Windows 98 machine. I captured the mouse clicks and screen changes (in real time) as I ran through the process, saving it to a Macromedia Flash file. I then created a little Web page on one of my Apache servers, that described how to start Mozilla Mail and included a link to the Flash file. Instead of asking me how to do it, she can now just click on the video tutorial.

Screen: an introduction and beginner's tutorial

Post date: April 15, 2005, 23:04 Category: Software Views: 2519 Comments
Tutorial quote: Most modern Unix-based operating systems (e.g. Linux, MacOS X, and BSD) come with a little console-mode utility called GNU Screen. It's a powerful tool in the hands of the console warrior, a veritable Swiss Army knife of text-mode human-computer interaction.

This utility, despite its considerable usefulness, goes unused by a great many people. Why is this? Few people even know it's there, and those that do rarely understand the problem it solves. In this article, I will explain what screen does for you, and provide a simple set of instructions for accomplishing basic tasks using screen. My audience is those that are skilled with the command line but who have little or no experience with screen itself.

Byzanz - free opensource Desktop Recording (command-line) tool

Post date: October 11, 2008, 22:10 Category: Desktop Views: 3501 Comments
Tutorial quote: Byzanz is a free opensource GNOME based Command-Line utility to capture desktop recording software for linux. This should probably be the coolest command-line utility that I have seen in recent days. Byzanz records your desktop session to an animated GIF. You can record your entire screen, a single window, an arbitrary region or even follow the cursor. Given that it is only a GIF format makes it even more an interesting proposition as the file size is going to be very small.

screen: Keep Your Processes Running Despite A Dropped Connection

Post date: December 12, 2006, 20:12 Category: System Views: 2735 Comments
Tutorial quote: I guess you all know this: you are connected to your server with SSH and in the middle of compiling some software (e.g. a new kernel) or doing some other task which takes lots of time, and suddenly your connection drops for some reason, and you lose your labour. This can be very annoying, but fortunately there is a small utility called screen which lets you reattach to a previous session so that you can finish your task. This short tutorial shows how to use screen for just this purpose.

Installing Solaris using JumpStart technology on an Intel laptop

Post date: April 13, 2005, 05:04 Category: Installing Views: 3742 Comments
Tutorial quote: An interesting use of Solaris 8 on a PC laptop is for use with the JumpStart technology. It has never been so easy to install, re-install, or restore a server before.

As I am as a contractor, I am more on the road than in my own office, so I need a laptop, and preferably with Solaris installed, as I am focusing on Sun's products and applications.

Through the years, I have discovered that one of the most common scenarios is that a client needs a server installed, either because they just bought it, or need it re-installed, or recovered.

This article covers how to save time when installing servers, using the JumpStart technology on a laptop with Solaris for Intel.
