Making Python Programs Blazingly Fast

Let’s look at the performance of our Python programs and see how to make them up to 30% faster! Python haters always say, that one of the reasons they don’t want to use it, is that it’s slow . Well, whether specific program — regardless of the programming language used — is fast or slow is very much dependent on the developer who wrote it and their skill and ability to write optimized and fast programs. So, let’s prove some people wrong and let’s see how we can improve performance of our Python programs and make them really fast! Timing and Profiling Before we start optimizing anything, we first need to find out which parts of our code actually slow down the whole program. Sometimes the bottleneck of the program might be obvious, but in case you don’t know where it is, then here are options you have for finding out: Note: This is the program I will be using for demonstration purposes, it computes e to pow...

What Why How SDN..???????

What is SDN? If you follow any number of news feeds or vendor accounts on Twitter, you've no doubt noticed the term "software-defined networking" or SDN popping up more and more lately. Depending on whom you believe, SDN is either the most important industry revolution since Ethernet or merely the latest marketing buzzword (the truth, of course, probably falls somewhere in between). Few people from either camp, however, take the time to explain what SDN actually means. This is chiefly because the term is so new and different parties have been stretching it to encompass varying definitions which serve their own agendas. The phrase "software-defined networking" only became popular over roughly the past eighteen months or so. So what the hell is it? Before we can appreciate the concept of SDN, we must first examine how current networks function. Each of the many processes of a router or switch can be assigned to one of three conceptual planes of operatio...
