Byte Sex

Byte-gender; not, "Yes! Please!"
Good! Now that I have your attention let's solve a relatively simple problem, byte sex. A less sensational name for this concept is byte endianess. This is one of those concepts that you should at least be aware of, even if you don't have to pay much attention to it in your day-to-day work. Each CPU architecture has it's own definition for memory. One of these properties is the endianess format of data registers. This is the first issue that I address for Network Alchemy.

C++: using and namespace

adaptability, portability, CodeProject, C++, maintainability Send feedback »

using and namespace are two of the most useful C++ keywords when it comes to simplifying syntax, and clarifying your intentions with the code. You should understand the value and flexibility these constructs will add to your software and it maintenance. The benefits are realized in the form of organization, readability, and adaptability of your code. Integration with 3rd party libraries, code from different teams, and even the ability to simplify names of constructs in your programs are all situations where these two keywords will help. Beware, these keywords can also cause unnecessary pain when used incorrectly. There are some very simple rules to keep in mind, and you can avoid these headaches.

Template Meta-Programming

adaptability, CodeProject, C++ Send feedback »

Over the years I have learned to value the maintainability of my code first. Then I make the proper adjustments if I discover a section of code that needs to be ported, optimized or reworked in some other way. With this in mind, I thought that template meta-programming had no place in production code. I believed that meta-programs were a novelty, clever displays of skill, and not capable of much more than the trivial implementations of a factorial or Fibinacci sequence calculation. I have completely changed my mind on this topic and will show you how meta-programs can provide value and create the most maintainable implementation possible.

Abstraction Layers of the Human Body

general, adaptability, CodeProject Send feedback »

I think that almost no one would disagree that the human body is a very complex structure. Most of the complexity is hidden from our view. I would like to make a literal comparison between the human body and abstraction layers, as though the body was defined in software. I want to hopefully connect the dots for many to help convince you of the ultimate importance of a well defined and protected interface.

At the outer-most level there is the body itself where a small sample of its interfaces are capable of:

  • Sensory input is given in the form of the 5 senses.
  • Communiucation can be expressed with a variety of means:
    • Speech is expressed with the mouth
    • Signals expressed with sign-language
    • Emotions conveyed with body language
    • Pheremones and other more subtle message transports
  • Energy and medications are administered through a finite number of orifices.
  • Waste and excrement are ejected through well defined interfaces. (When things leave the body from unexpected orifices, this should be concerning.)
  • When the body is sick, it expresses symptoms in many ways. Some of them are only internally detected, others are clearly visible or audible.

Controlled Access of Global Data

adaptability Send feedback »

Global variables have a way of becoming a binding element that tightly couples modules. Certain desired behaviors may only occur because of side-effects created when the value of the variable is changed. Conversely, undesired features seem to intermittently appear in ways that cannot reliably be reproduced. As more global variables that are added to the source code base, the system seems to become more unstable. At this point, removing or altering set of global variables in the system becomes a monumental risk, rather than a safe and simple task.
