BallWorld Screen Saver

Overview:

My last Java programming assignment for my class at the University of Akron was called "BallWorld."  Its details can be found here.  I will not post any source code here, but I will post an executative JAR file that will run the screen saver.  Anyways, the final project of the BallWorld project was kind of cool, so I modified it a little bit to make a pretty neato screen saver.  You can download the project here: BallWorld.zip.  The zip file contains a .JAR, an .EXE, and a .JOB.  The JAR file should execute the screen saver on any operating system.  The EXE file works only on Windows.  The JOB (Windows Task Scheduler) file can be used to automatically run the EXE file after a specified amount of computer idle time.

Details:

The EXE file was created using a program called Launch4j.  Launch4j simply takes a JAR file and converts it into a Win32 EXE.  Obviously, this destroys platform-independency, but... it does have some advantages.  For example, if a Windows user does not have the Java Virtual Machine installed (JRE), then the JAR program will not run.  On the other hand, the EXE file determines whether or not Java is installed.  If it is not installed, it will send the user to Java's download website.  If it is installed, then the JAR file is loaded into memory and the Java Virtual Machine runs it.

Download:

Again, you can download the project here: BallWorld.zip.
Please contact me with any questions or comments.  Thanks and enjoy!

Today's Quote

This is simply a brain dump.  I'm sleepy, and I want to type out some of the thoughts currently in my head. "Luck is where preparation and opportunity meet."  This is so remarkably true, and today I'm making it a mantra.  I believe that luck is merely an illusion that we perceive, but it truly when we have prepared ourselves for the right opportunity... and then a great opportunity comes along.  Many great opportunities pass us by every day.  Once we begin to recognize them and prepare for them, then we start to experience the thrill of luck. Interestingly, as described in "Good to Great", Mr. James Collins talks about how "Level 5" leaders often attribute their great success to luck .  That's a humble way of saying, "I planned on taking advantage of every opportunity ."   Hmmm...

JavaScript Sticky Footer and Scroll Effect

This post talks about two different HTML/JavaScript effects: How to keep a page footer stuck at the bottom of the browser window. How to create a scrolling <div> without using a scroll bar OK. So... you have a website. You want a header stuck at the top of your page and the footer stuck at the bottom of your page. The stuff in the middle, you want to be able to scrollable. But, you don't want those ugly scrollbars to the right of your scrollable text. Maybe, instead, you'll have up arrows and down arrows above and below your <div>. When you mouseover the arrows, the text in the <div> will move up or down and create a scrolling effect. Suppose your page looks like this... <html> <head> <title>Test</title> </head> <body> <div style="position: relative; width: 700px; margin-left: auto; margin-right: auto;"> <div id="header">Header</div> <div id="scrollUp&q
