Traveling Ruby (multi-platform portable Ruby binaries)

Traveling Ruby consists of a set of multi-platform portable Ruby binaries, which can be used to distribute Ruby-based products and run them even in machines where Ruby is not installed. It’s very useful, as you can also use it to pack multi-platform applications.

You can check the project’s home page here:

Traveling Ruby is a project which supplies self-contained, “portable” Ruby binaries: Ruby binaries that can run on any Linux distribution and any OS X machine. It also has Windows support (with some caveats). This allows Ruby app developers to bundle these binaries with their Ruby app, so that they can distribute a single package to end users, without needing end users to first install Ruby or gems.

It can run on

  • Linux x86.
  • Linux x86_64.
  • OS X
  • Windows





Code Smells detectors

A Code smell is an interesting Software Engineering concept. According to Wikipedia, a Code Smell

“refers to any symptom in the source code of a program that possibly indicates a deeper problem.[1] According to Martin Fowler, “a code smell is a surface indication that usually corresponds to a deeper problem in the system“.[2] Another way to look at smells is with respect to principles and quality:[3] “smells are certain structures in the code that indicate violation of fundamental design principles and negatively impact design quality“.

Common code smells include:

  • Class-level smells
    • Large class, Feature envy, Inappropriate intimacy, Refused bequest, Lazy class/freeloader
  • Method-level smells
    • Too many parameters, Long method, Excessively long identifiers, Excessively short identifiers, Excessive return of data
    • Excessive use of literals, Cyclomatic complexity, Downcasting
    • Orphan variable or constant class
    • Data clump

Code Smells detection tools

Some free code smell detection tools (which perform static code analysis) include:


Most of these smells lower your code’s quality and maintainability. Be sure to include some of these detection tools on your development processes, as well as appropriate coding standards. Automatic noncompliance detection can be accomplished by adding these tools to your build process.
