Java has become a confusing world. Five years ago, there were few decisions to make once you started programming in Java—you used AWT for graphical user interfaces, sockets for network programming, and hacked together everything else you needed. Since then, though, the APIs available for the Java language have grown, and grown. . . and grown. Now you can dabble in Swing, servlets, Enterprise JavaBeans (EJB), JavaMail, and more. Additionally, there are now packages of APIs, like the Java 2 Micro Edition (J2ME) and Java 2 Enterprise Edition (J2EE). While these packages seem to be nicely wrapped bundles of useful APIs, they don t help the average developer figure out how to piece together the APIs contained in these packages. Though it s simple to find documentation on the individual APIs, getting the "big picture" is difficult, at best. One of the most interesting, but difficult, aspects of Java today is building Java enterprise applications using the J2EE package.

Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switching the port on or off, the user can pulse it for a short period (e.g. 鈥淩eboot remote server鈥?.

Playfair Cipher 1.not even the large number of keys in a monoalphabetic cipher provides security 2.one approach to improving security was to encrypt multiple letters 3.the Playfair Cipher is an example 4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair Playfair Key Matrix 1.a 5X5 matrix of letters based on a keyword 2.fill in letters of keyword (sans duplicates) 3.fill rest of matrix with other letters Encrypting and Decrypting -plaintext is encrypted two letters at a time 1. if a pair is a repeated letter, insert filler like X’ 2. if both letters fall in the same row, replace each with letter to right (wrapping back to start from end) 3. if both letters fall in the same column, replace each with the letter below it (again wrapping to top from bottom) 4. otherwise each letter is replaced by the letter in the same row and in the column of the other letter of the pair
