I don't really have time to go into great detail at the moment, but I just had to tell the world that OS X 10.5 "Leopard" sucks. I'm not an early adopter, 10.5 came out in October of 2007 and I'm running Mac OS X v10.5.3 on Dual 2 GHz PPC G5 with 2.5 GB DDR2 SDRAM.

Installing OS X 10.5 was flawless as always so no trouble there. But as soon as the thing booted up I instantly realized that several things were going to have to change!

I've had a lot of great ideas for interesting projects for over the summer. Some examples are a home crafted PCB CNC Mill. I already scavenged a lot of parts and have already performed a significant amount of planning. I also have some really neat WiFi modules sitting on my desk from ConnectOne, Socket iWiFi to be exact. Lots of interesting applications come to mind for that module. But all of these things are just going to have to wait.

Here are a couple of Integrated Circuit (ICs) symbols that I have built in OmniGraffle for use with digital logic design. The stencils are very simple but they are items that I have made and have used repeatedly for one of my classes when I don't really need a full blown schematic or wiring diagram.

This information is incomplete, missing precise definitions, examples, and confirmation of information supplied. Read on if you like but finding another source for the information might be the better idea for the time being.

When we say "Signal" we are really talking about anything that is a function of time.

Typically, signals can be categorized as either analog or digital. Where an Analog signal is a continuous function of time and where Digital is a discrete-time signal of certain instances of time.

I don't know that I have formally stated this but I am enrolled in EE 2372, Modern Digital System Design. The class so far has been in regards to digital logic, boolean algebra. Things have been going well and my grades have been rather good. Though I am not happy with the last two to three assignments I have submitted due to unfortunate time constraints with no one to blame but myself. But I had the chance to redeem myself to myself as our first "Project" came around.

One of the main concept of Digital Logic design is Boolean Algebra. Boolean Algebra was developed by George Boole in 1849. In 1904, the postulates that we use today were presented by Huntington. Boolean Algebra is not an algebra of numerical values but of logical values.

Boolean Algebra is built upon a closed number set composed of 0, 1, and other variables that can accept the values of 0 or 1. This system is perhaps more commonly known as the binary number set.

It seems that a lot of start up blogs, websites, or whatever you choose to call them these days do a post rationalizing their busy lives and promising more content and further development in the near future. And though I doubt that these revelations and promises are not ill intended they often never reach fruition and as such I am not making any such claims.
