The following links represent various things that I am interested in.
Who doesn't love looking at the night sky? Stellarium is a planetarium program available on several platforms.
If you have an Android phone, Google Sky Map is also a nice thing to have. (Google Sky Map is available on
Google's Play Store.)
Many people like messing around with graphic images, in the style popularized by Photoshop®. GIMP is a
free alternative available under multiple platforms.

What is ray tracing? Pretend you have a camera and empty 3D space. You specify the objects you want, and their
textures. You specify the lighting you want. Then, you use the ray tracing program to render it. The ray
tracing program essentially says, "I am a camera. Light is bouncing off objects in this scene and entering my
lense. What does it look like?" The ray tracer renders a realistic scene, and provides perspective based on
where you placed the objects, and shadows based on the lighting. Take a look in the gallery on the following
site. People have done some wonderous things.

Are you tired of or just hampered by the Windows operating system? Linux is a UNIX variant which runs on
several architectures, including the i386 and amd64 architectures. Running any UNIX variant does require a bit
of a learning curve. But, if you want to unleash your machine and give your computer a multi-user environment
with full network capabiltiy, and if you like very powerful and free software, Then Linux is for you. There
are many Linux distributions available. Some are purported to be easier to use than others. One favorite seems
to be Ubuntu. I got used to Debian and don't want to switch. Shop around and choose what's right for you.
Below is a link to the Debian home page.

When I was first introduced to computers, you couldn't do much with them unless you knew how to write a
program. I still love programming to this day. My favorite language is C++. The current version, C++11, is a
very rich language which seems to offer limitless possiblities. Below is the site of the creator of C++,
