Internet Explorer is not responding: try troubleshooting steps

This is the best way to let us know when Internet Explorer stops responding. Problem description It's hard to determine exactly what causes Internet Explorer to stop responding (this is also called an application hang or, simply, a hang), but it's usually due to one of the following: • Spyware, adware, or other malicious software: If you have downloaded free software from the Internet, you might have inadvertently downloaded spyware with it. Spyware is software that can display advertisements (such as pop-up ads), collect information about you, or change settings on your computer, usually without your permission. Don't worry, you can usually remove spyware. • Internet Explorer add-ons: Add-ons are software "extras" that add features or tools (an Internet toolbar for example) to Internet Explorer. • Computer viruses: If your computer has a virus, the virus can cause Internet Explorer to stop responding. ________________________________________ Troubleshootin...

A Brief History of Javascript

When the World Wide Web was first created in the early 1990s all web pages were static. When you viewed a web page you saw exactly what the page was set up to show you and there was no way for you to interact with the page. Being able to interact with a web page - have it do something in response to your actions - required the addition of some form of programming language to "instruct" the page how it should respond to your actions. In order to have it respond immediately without having to reload the web page this language needed to be able to run on the same computer as the browser displaying the page. At the time there were two browsers that were reasonably popular - Netscape Navigator and Interas the first to bring out a programming language that would allow web pages to become interactive - they called it Livescript and it was integrated into the browser (meaning that the browser would interpret the commands directly without requiring the code to be compiled and without...
The history of computer viruses A Bit of Archeology There are lots and lots of opinions on the date of birth of the first computer virus. I know for sure just that there were no viruses on the Babbidge machine, but the Univac 1108 and IBM 360/370 already had them ('Pervading Animal' and 'Christmas tree'). Therefore the first virus was born in the very beginning of 1970s or even in the end of 1960s, although nobody was calling it a virus then. And with that consider the topic of the extinct fossil species closed. Journey's Start Let's talk of the latest history: 'Brain', 'Vienna', 'Cascade', etc. Those who started using IBM PCs as far as in mid-80s might still remember the total epidemic of these viruses in 1987-1989. Letters were dropping from displays, crowds of users rushing towards monitor service people (unlike of these days, when hard disk drives die from old age but yet some unknown modern viruses are to blame). Their computer...
