Binary Negative Space

The four most popular methods for encoding (representing) negative binary numbers are known as “sign and magnitude”, “ones’ complement”, “two’s complement”, and “Excess-K”. There are alternative methods as well that aren’t as popular such as negative binary where the number base itself is actually negative (being negative 2).

Magic Hexadecimal and High Octane Octal

That’s all there is to hexadecimal and octal. As you can see, hopefully, it’s not too complicated and is quite a bit like binary. Hexadecimal and octal were introduced to me when I was editing data files in a text editor that displayed the hexadecimal values of each byte as well. It was a pretty useful program.

Algebraic Tron

We’ve discussed how binary representations are fed into a processor which takes that input and goes through a series of steps depending on that input to create an output, but how do we actually make that happen? To do so you would choose a programming language, or create your own, dependent on the desired level of control over the machine.

The Wonderful World Of Binary

I remember learning about binary when I was just an elementary student from a How Stuff Works book. I must have checked out that book five times, re-reading the same material. I was fascinated with it, but pretty soon I wanted to know more. Unfortunately, my reading material was limited for several years before I could advance to higher topics.

What Is A Computer?

This question is technically very broad. Computers have existed ever since the first abacus was invented. A computer is anything that helps you compute, or perform mathematics. This definition has been vastly expanded in recent decades due to technological advances. At the core of it all though, the definition is the same.

Computer, This Is User

The computer itself (the object you plug everything else into) is the core of the whole construction. Without this part, you wouldn’t have a computer set-up at all. It is the piece you plug everything into because it processes and manages everything else.

What Is Philosophy?

Philosophy was one of those subjects that you learned about on your own, apart from school.  It was a place where I could shoot ideas out into it and see where they go, no textbook, no teacher.  I probably drove my brother crazy with all my, often hare brained, ideas and beliefs.

Super Power NecoMimi Ears!

When I first built my short lived fursuit Larry the Lab Rat, I wanted to have moving ears.  So, I found this thing on the internet called NecoMimi ears.  They’re ears that move according to your brainwaves. They were incredible.  They operated by using a sensor on your temple and one hooked to your ear.  The ears would move depending on your mood.  Well, it kind of worked, either that or my brain is really jittery. However, it had some problems.  I had to embed the thing into my rat head.  Even though the head was close to my head it was difficult to get the device on.  For one, it was hard to access the batteries, for another we had to make sure the ears were clear.  However, I needed the batteries to be external to the head.  I couldn’t change the batteries while it was in my head, and it would be easier if I could connect batteries externally. My half-brother Ian suggested I extend the battery life of the device if I was going to put the batteries on the outside.  I discovered that if I add more batteries to the circuit, anywhere on the circuit, that would extend the life of the necomimi.
