So I'm going to attempt to help solve those very valid, logical questions.

Most often programming is achieved by typing in a certain "Programming Language" into a normal text editor, then compiled (or 'made' into machine language that the computer can understand) into native or interpreted code, which I'll explain soon. There is also several programs that are called IDE's or Integrated Development Environments. These are useful in several aspects. For one, they look similar to a normal text editor, but they color coordinate your code, to make it easier to read at a glance. They can also perform automated tasks for, that ease up the amount of typing you have to do. They also provide a single area to write, compile, link, test, and run your programs, without having to use several different utilities. But you are not forced to use an IDE, it just makes your job, as the programmer, slightly easier. Now, you can't just use any IDE you want, most often, IDEs are specialized for a certain language.

go to [url]www.seclude.org[/url] it's an entire messaging system, like aim or msn or whatnot. It's written in Java, and it's fully open source and free to download. It also implements some very advanced encryption techniques. It's quite possibly the safest way to talk over the internet. Download it and see how they conquered this problem.
