Computer Retrospectives - How the Operating System came to be

December 3rd, 2007

by ZACH HOPE

Many young people nowadays take for granted the mouse based operating systems that have been the standard since the 1980s. The mouse is the main step forward that I can remember in the evolution of the PC. When I was a kid, the personal computers that everyone wished they had were the ZX Spectrum and Commodore 64. The Commodores were basically bulky keyboards that connected into your television, and a tape recorder to store and load data, programs, or games. You could hardly refer to it as an operating system; there wasn’t even a mouse and it was totally different to Windows XP or Mac OS 9. When you got a game for these early home computers, on the reverse of the case it had instructions on the painfully slow loading procedure. I can’t really remember, but I think you had to type in “Run” or something and press play.

The Introduction of the Pointing Device

My first memories of trying out a trackball were when using a Commodore Amiga 500 – one of the most desirable gaming PCs of the mid to late 80s. The Commodore Amiga did have a primitive operating system but it was capable of displaying only a few colours and overall it looked pretty rubbish. Then again, this was the first step away from having to be able to code to operate a computer. The mouse is much more instinctive than typing computer code and played a crucial part in helping to grow the home computing market.

Whist at University, a buddy of mine passed on a fascinating anecdote about the invention of the mouse. His father was an employee at Xerox and had maintained the group was the originator of the mouse. Then Steve Jobs saw the contraption and included it into his Apple computers. I don’t know what sort of legal wrangling arose, but the intellectual property for the mouse has to be up there with the most well-paid ever conceived. There must have been tons and tons of the gadgets manufactured.

The launch of the mouse can be considered the dawn of the operating system as it appears today. Microsoft launched Windows 3.1 which was very ugly even in those days. Apple’s OS 7 was a lot more good looking and simpler to use. The problem was that the programs on Windows were in fact suited to corporate use. The Apple computer was meant for the artistic inclined marketplace – becoming the operating system for computer art, and graphic design. The two OSs were complete opposites, you couldn’t even exchange a floppy disk between them, they had their own printers, and you could forget about networking them. Step by step over the next 20 years the disparity was reduced, and in 2006 Apple systems started to use Intel processors so they were even able to run Windows. Nobody saw that coming.

Microsoft Windows has always been playing catch-up to Mac OS when it comes to aesthetics. Even with Vista, a lot of people would still rather have OS X Leopard – but that might just be to do with Bill Gates taste.

What the Future Holds

Looking towards the upcoming gadgets of tomorrow, there are some very promising avenues for innovative input devices. The mouse became the ground breaking contraption for operating systems in the 80s, and in 2007 the touch screen could well follow in it’s footsteps. The iPhone doesn’t need mice, trackballs, and keyboards, because it has swapped them with a touch screen. Although typing is a little tricky with no sensation of a key press, it has forged new territory in the advancement of the operating system. It has much superior portability and handiness - something that is certainly going to get better and better in forthcoming years.

How to Record your computer screen without camera

December 1st, 2007

by SHARE WONDER

Why do you need to record the computer?
“What’s wrong with my computer/this tool?” When you have problems of trying new applications or system, and have no idea of how to describe what happened on your computer, you may need a tool to mirror your operations, and then send it to a computer guru or technical support for help. It need to show exactly what you have done and how can this happen, so the technical staff can understand you clearly and give you the quick solution within minutes. It’s efficient for you to get the quick response.

Do you really need a camera to record your computer screen? A camera face to your computer is not the best way for these purposes. First, the camera can not record the screen exactly. Second, you can not edit the video by adding some instructions or narrations. Third, the video file is too big for web sharing and transmission.

Maybe you need an application to record your screen, not a camera! Screen recorder tool helps you to record the screen to mirror all of your operations without camera. You can add tips to highlight the important functions. Furthermore, you can add narration from microphone easily to enhance the demo. At last you can publish the flash movie and transmit to the technical guys. As you know, the flash format with smaller size and better for network transmission.

It’s very popular that these demo creator tools work with three steps, record screen, enhance with annotations and publish to movie. A good one in this area I want to highlight is Wondershare DemoCreator, with the excellent functions of Auto-annotation and click zone. It’s suitable for individual uses, no need of programming or media skills.

Especially, DemoCreator’s build-in ready-for-use after capture, adds the annotation and click zone to recorded screens automatically when recording is being done. After recording is completed, you can just publish the movie immediately. The actions of mouse movements and application operations are recorded automatically already. Audiences can know how to use your products step by step when playing the demo. Furthermore, you can add some animations or interactivities to enhance the software demo, thus making the demo more animated and interactive.
