It has been almost a month since my last post and I feel bad because of that, but I have good excuse for not writing - during previous weeks I managed to completely redesign and upgrade this site. I did it because I did not like my previous design (something about colors) and I needed integration with social services like Twitter and Facebook.
Almost all GUI applications have same behavior when they are closing. Window is closed when the user presses the "X" button or by some other means (menu item, ALT+F4). If the window contains some unsaved data it warns the user about it and allows him to cancel the closing. If the user chooses to close it, the window is removed from the screen and, optionally, the entire application is terminated.
Developers tend to use System.out.println and equivalent calls for debugging and logging in their applications. Please stop doing that, there are better ways.

In this tutorial I am going to describe the MVC pattern and show you a simple implementation in PHP.

In my past, I programmed all kinds of software for many different clients. Each time when I worked on some project I had encountered problems that I solved previously but I forgot how did I solved it. It appears that my mind has its memory limitations so I needed to overcome it somehow. This site is designed to overcome memory limitation of my mind - forgetness. On this site I will write about my computer development experiences so when I do forget something I can simply look it up on this website. Why not just write a solution on a piece of paper?
