Los defaults malvados

Trabajar en un proyecto con mucho código heredado siempre es una fuente de grandes aprendizajes. En esta ocasión les presento a los "defaults malvados", como a mí me gustan llamarlos. Son partes de código que pueden hacer mucho daño en una aplicación. Veamos cómo…

"Los verdaderos desarrolladores no usan if". ¿Por qué alguien querría eliminar el if? ¿Qué tiene de malo? Aquí les cuento por qué y cómo lograrlo.

Reifying problems in our software: a short story

Reifying problems in our software: a short story

Yet another lesson from a large project with legacy code. Did you happen to see “known issues” in software that you have worked on? And how many times have you seen them “solved” with “quick fixes” or “workarounds”?

Classes or Prototypes in Python

Classes or Prototypes in Python

What would happen if I wanted to play only with objects on Python, using other objects as prototypes? I’m going to show how we can benefit from the meta-programming tools available on Python in order to do that.

The Evil Defaults

Working on a project with a lot of legacy code always leaves good lessons. This time I’ll present you what I like to call “evil defaults”, pieces of code that can do a lot of harm in any software project.

Collection Filters in Ruby

Collection Filters in Ruby

There should be a filter object, and it should be placed between the user and the filtered object. Imagine you are modeling a person using a pair of glasses...

Be careful with the mocks

There are null reasons

This post will try and maybe fail to convince you that using `null` in your code is an error. For those of you willing to listen, here are my reasons to stop using it.

"Real devs don't use if". Why would somebody want to eliminate the if clause? What's wrong about it? Here I tell you why and an example on how to do it.

State and Polymorphism with Clojure

State and Polymorphism with Clojure

Santiago shares with us how some things in functional programming can be done similarly to OOP!

Rock Your Ruby: The Value of Value

Rock Your Ruby: The Value of Value

Go ahead and ask the developer sitting next to you what is the thing that loves the most about Ruby. It should come as no surprise that simplicity, flexibility and expressiveness are the main reasons Ruby junkies just can't get enough of it.

OOSCM: Object Oriented SCM - Beyond files - ESUG 2010

OOSCM (Object Oriented Software Configuration Management) is a tool we are developing to better support traits that are unique to object oriented development. Current SCM tools (CVS,SVN,GIT,Monticello, etc) are file based solutions, the file is the minimum versionable element, but when developing with objects files are not
