Computer Science Quotes

On this page we can find several of the most cool quotes from computer scientists:

http://goto.ucsd.edu/~mstepp/programming.html

A few of them:

"The fastest algorithm can frequently be replaced by one that is almost as fast and much easier to understand."
     - D. Jones

"The sooner you start to code, the longer the program will take."
     - R. Carlson

"Computer Science is no more about computers than astronomy is about telescopes."
     - Edsger Dijkstra

Nature cannot be fooled

A very famous quote from Richard Feynman.

"For a successful technology, reality must take precedence over public relations, for Nature cannot be fooled."

This quotes is not strictly for space shuttle construction, but also it can be applied for Software Engineering, particularly for estimation when planning a new development project.

Big-O Comparison

Usually it's easier to see in a graph the complexity of functions:

The Scale Cube

Good example of  cube demonstrating the 3 factors necessary for scalability in microservices (it could be projected to different domains as well). Therefore if you scale in any axis will have an impact in another

Dietzler’s law

Interesting law from Neal Ford quoting his colleague Terry Dietzler:

Dietzler’s Law for Access

Every Access project will eventually fail because, while 80% of what the user wants is fast and easy to create, and the next 10% is possible with difficulty, ultimately the last 10% is impossible because you can’t get far enough underneath the built-in abstractions, and users always want 100% of what they want.

Maven subprojects

A raw workaround, and work directly on a parent pom.xml into an eclipse workspace:

• create workspace
• create parent project
• copy files/directories, overwriting (subdirectories)
• import thru "Existing Maven Projects", and select parent project

however, it doesn't work as expected... I think the copy to directories is wrong, and only it should be a reference to the origin.

A much better explanation: http://websystique.com/maven/creating-maven-multi-module-project-with-eclipse/

UPDATE1: In the end, there is a quick difference as workaround: just import directly the parent pom.xml

Bueno Bonito Barato

En Gestión de Proyectos (informaticos en particular), no existe el BBB (Bueno, Bonito, Barato) tal como en la vida real, un Trilema clasico.

Por el dominio formal del tema, no se utiliza tanto estas siglas, pero sin dudas existen y es un tema tratado en este ambito.

Podemos ver en wikipedia (ver referencias originales) que se usan sinónimos, tal como:

Fast, Good, and Cheap,

Y de la misma forma, se solicita tomar solo 2 de ellas (Pick any two), en donde solo 2 de esas características pueden ser elegidas, ya que la tercera no sera cumplida por motivos de las anteriores :O

En fin, la idea es recordar este buen thumb-rule en el dia a dia de un proyecto...
