Picking a Motherboard and Processor to use with Virtualization

When selecting you hardware, there are many factors to consider; How many Virtual Machines do you want to run at a time? How busy will these Virtual Machines be? If you are getting ready to P2V a bunch of virtual machines, then you should use Perfmon (In a Windows Environment) to take a benchmark before proceeding. In this article, I am not going to focus on sizing your environment, but rather making sure that the hardware you select is going to be compatible with what you want to do. **Note, this Read more […]


Machine learning Models vs Algorithms

Machine learning is very prevalent these days. But you may not understand all of the lingo. In this article, we will discuss what the difference is between a machine learning model and a machine learning algorithm. We will also discuss when to use what models, and a few, types of machine learning algorithms. Models Machine learning models are at their core, very complicated statistical formulas. You give the model a set of inputs, these inputs are run through your formulas, and then you get an Read more […]


How to Install cURL on Windows

This article describes how to install and use CURL on Windows. Curl is a free command line utility used for transferring files using various protocols. Most commonly it is used for transferring files over HTTP(S). cURL comes natively installed on unix based operating systems such as MacOS and Linux. But windows is left out. Now that we have powershell on windows, you can get some of the functionality of cURL using various cmdlets like invoke-webrequest. However, if you are used to using a unix toolset, Read more […]

Published Applications vs Application Virtualization

Portability of Software is the ability to run the same software on a number of different systems.  One of the goals of many software developers are to be able to write the application once, and run it on as many platforms as possible.  A similar goal of Systems administrators is to ensure you can run software with as few conflicts as possible Typically when one thinks of portability of software in the context of virtualization, two things come to mind, Published Applications and Application Virtualization.

Installing and Configuring Kernel Virtual Machines (KVM) on Fedora/Redhat/Centos

KVM Stands for Kernel Virtual Machine. KVM is a virtualization technology built into the Linux Kernel based on QEMU (Quick Emulator) and is used for server virtualization. QEMU allows for virtualizing hardware, all the way from a complete hardware stack to a single device. KVM basically takes QEMU and allows it to use hardware extensions to achieve better performance. KVM is the default hypervisor in the Open Stack project. **Note: This content was ported from our old website. So the information Read more […]


Error Handling in Python using With and Try

In this article we will discuss error handling using Python With Statements Try/Except/Finally statements, show how to use these in combination, and compare how it works to try/catch code blocks in other languages.What is error handling?Error handling is when you put in some extra code to tell your script what to do when things don’t go totally to plan. Perhps you try to open a file that isn’t there. Or perhaps a user puts in unexpected input.Without any error handling, your program or script Read more […]


Creating word clouds with Python

Creating word clouds in Python is easy thanks to a few open source libraries. Today, we weull use the ammueler word cloud library and matplotlib to draw some word clouds.Word clouds are useful visualization tools for looking at the general theme of a document. As a document contains more instances of a given word, that word gets larger in the word cloud, and other words get smaller.PrerequisitesBefore we get started, you will need to install the prerequisites by running the following commands:

If Read more […]
