UML to Code Generators
A long time ago I came across tools that generate code through UML diagrams. Using such tools, you design the software using a computing tool with drag and drop features. Once you are done with the visual design, you could generate the corresponding code using clicks of a few buttons. I was wondering what is the state of the art right now.

Manipulating Software Through Design Patterns
Basically, design patterns are templates that you apply to your software during the design time. When you convert your software to code, finally, design patterns convert into patches and wrappers to your software. Normally they hide behind themselves the intricate details of objects they are applied to. As a result, they provide an easy to use interface to the developer. The developer, in turn, can use them to grab the desired objects.

Of Frameworks and Libraries
I was delivering a lecture on design patterns the other day. A student inquired whether design patterns were libraries. I had to spare some time to explain that this wasn’t the case. A library is a compiled code (of an application) that you can use in any program. By using I mean that you can call its objects, their functions, and properties in another program. This is a great utility of libraries. Consider that you have created an application that has a lot of functions to compute simple mathematical formulae. These could be anything like addition, multiplication, logarithmic, exponential or sinusoidal functions. One thing you can do is to compile it to create an executable program. The other thing you can do is to compile it to create a library. An example of the former is any executable program that a compiler creates. An example of the latter is a “jar” file created using the java compiler. Jar is an acronym for java archive(s). It is called an archive because it is a library that contains a compiled version of your application (your mathematics library).

Illuminance vs Luminance
It is sometimes worthwhile to understand how various metrics related to the measurement of light intensity work. Two of them are illuminance and luminance. They can sound really mundane and fool the subject into believing that both are actually the same thing. However, they are not. As a matter of fact, they are quite different.
