I'm in the process of considering which programming languages I should devote the majority of my coding studies to. I'm a 2nd year CS student, majoring in IT security.

What I want to do/work with:

• Intelligence gathering
• Relational databases
• Virus design
• Snort network IPS

Current coding experience (what I'm going to keep):

• Java - intermediate
• HTML5 - intermediate
• SQL (MySQL, Oracle 11g) - basic
• BASH - basic

I'm going to need to learn (at least) one of the following languages in order to be successful in my field.

Languages to add (at least 1):

• Ruby (+Metasploit)
• C++ (virus design, low-level driver interaction, computationally intensive applications)
• Python (import ALL the things)

My dilemma: If I diversify too broadly, I won't be able to focus on, and improve in a specific niche. Does anyone have any advice as to how I should select a language?

What I'm considering + why

• I'm leaning towards Ruby because of Metasploit support, despite lower efficiency when compared to Python.

Any suggestions based on real-world experience? Should I focus on Ruby, Python, or C++? Both Ruby, and Python have been regarded as syntactically similar to Java which my degree is based around. I'm going to be studying C++ in two years as a component of my malicious code class.

Thanks, Tyler
