This article was created for those who want to use functional programming in their career or who are learning new programming paradigms.
We will examine the basics of functional programming and how to apply it in Python. Good readings!
Introduction to Functional Programming
Functional Programming is a popular programming paradigm closely linked to the mathematical foundations of computer science.
Python is not a functional programming language, but it supports it because it is a multi-paradigm programming language.

configure the cpu speed to run at MAX speed all the time by adding the following parameter into the file /etc/cpuspeed.conf and restart the cpuspeed service:
OPTS="$OPTS -n -C -S \\"0 1\\""
On RHEL 5:
add the above parameters to /etc/sysconfig/cpuspeed or use the performance governor by adding the following parameter to the /etc/sysconfig/cpuspeed file and restart the cpuspeed service:
On RHEL 6:
configure the performance cpuspeed governor as above for RHEL 5 and add the following kernel boot options and restart the server. More information available in the Low Latency Performance Tuning for Red Hat Enterprise Linux 6 article.
