Probably everybody knows the famous video game from 1984, programmed by Alexey Pajitnov: Tetris! The first time I played it was in the early 1990s when I received my first Game Boy, launched by Nintendo only a few years before. Since Tetris was included in the box, it was one of the first video games I ever played. |

Function Evaluator: Parsing & evaluating a function |

Two years ago I programmed a function plotter in Visual Basic 6. The plotter basically allowed the user to enter a mathematical function and other settings (like discontinuity detection, etc.) and the function was plotted. It allowed multiple functions on the same plot and had a lot of styling and coloring options. Now I intend to rewrite this program in Java in order to make it more platform independent. I will publish a series of articles as I develop the program. These articles are to be understood as a guideline if you have a similar project. |

Masking an email can amplify spam |

What happens if you open your mailbox? Most of the time you have many mails in your inbox, mostly spam. Many people ask themselves how senders get their addresses and if there is a method in order to protect them. First of all, a lot of spam messages are send randomly without knowing if the inbox exists or not. But this technique is very limited in the eyes of spammers. Therefore they have developed specialized webbots (i.e. programs that seek out webpages in order to find email addresses). If a site containing your email address is searched, the bot finds the address and it is being indexed automatically. |
