A home lab can be a great learning tool. However, many of the used servers available at discount come with a hidden cost: power consumption. This is exploration of more efficient alternatives.

AWS Game Day is a competition that allows participants to test their AWS skills in a risk-free environment, possibly discovering new services. Could this be the new eSport for System Administrators?

Distribution of software is rarely discussed in academic settings, leaving many to learn this by trial and error. In the case of a web application, this needs to be decided early, as it will shape the choices of technology and development methodology.

A HomeLab provides a proper learning environment for computer infrastructure and software and infrastructure. With over half a million members on the r/HomeLab reddit channel, it is impossible to deny the popularity of the hobby.

A hard lesson for any sysadmin to learn is to have an outage without even knowing it. The following describes how Technodabbler converted a simple #cron #monitoring into a light-weight monitoring solution.

Server hardware is typically mounted and operated in specially designed rack. Such hardware is designed from the start to be placed in these racks. However, when building a machine from scratch, finding a good rack mountable computer case can be a challenge. A couple of good options come surprisingly from

When building a homelab, noise is a common concern. Enterprise-level servers were never designed to be quiet. For those resourceful enough, you can build a sound proof cabinet. Here is how Technodabbler did it.
Programming
The way we develop and deploy Web Applications has changed a lot in the last 10 years. Typically, such a project would require skills in three fields : * Knowledge of a programming language to build a web applications. * Knowledge of system administration, as to manage the platform that will host the

In a Homelab, disk shelves are a simple solution to add storage to an existing server. Just add an SAS adapter for some extra external SAS ports and you are ready. On the r/Homelab sub-reddit [https://www.reddit.com/r/homelab/], older disk shelves, such as the NetApp DS4243

EDIT : The T20 might be a bit old, but Dell continued the series with the T30 and the T40. You might want to check them out. A server is a computer decided to providing one or more services. In the case of home offices, the most common type would be

One of the important aspect of Linux is its Open Source nature: everyone is free to contribute and no one "owns" Linux. This creates a great diversity which is both a strength and a weakness for the operating system. Wars over the best "distro" of Linux are fought with religious

A KVM Switch is a device that allows a keyboard, a video monitor and a mouse (hence the name) to be shared across multiple computers. This particular model, the Dell 2161DS-2, is commonly used in server rooms, where large numbers of servers only require a monitor and keyboard for troubleshooting.

Given the ridiculous number of high profile hacks, password security is more important than ever. Proper password etiquette can be summarizes to two rules : * Use strong passwords (composed of characters and digits, no dictionary words) * Do not reuse passwords in more than one place The problem is that passwords are

A few years ago, I was lucky enough to receive a Lego NXT Mindstorm [http://en.wikipedia.org/wiki/Lego_Mindstorms] kit as a gift from my wife. With it, one can build a robot using technical legos, motors and sensors. A special programmable brick is used to control the
