I have been programming in Python in one capacity or another since around 2000. That’s almost 15 years. Over those years, I’ve come to know the language fairly well. I originally came to Python from C and Perl, and it was quite refreshing to come to a language that is simple to use, has a consistent syntax and library, and is quite powerful.
A few weeks ago, a colleague came to me with an interesting bug: When running a child process with Python’s

A colleague asked me to look into a problem with him, mentioning that “Tlib hangs when we run it”. Tlib is a fairly large project that is written in Python.

To accomplish this feat, it uses several different methods for remote execution: SSH for running general shell commands, RPyC for executing arbitrary Python code remotely, as well as a couple of proprietary interfaces.

Disclaimer: This post is about software development, but it is more about the human side of it than about the technical side. This means you may enjoy it even if you’re not a software developer (or a technical person at all).
One of the recurring issues that I encounter as a software developer is that of having to decide where on the scale between YAGNI and NIH I want to be. You are probably wondering what the hell I am talking about

At work, I encountered an interesting problem: While testing the Fibre Channel (FC) scalability of a storage product, we needed to create a lot of FC connections between hosts and the storage system. This would in turn require a large number of FC Initiators, each of which having a unique World-Wide Port Name (WWPN).
