As we look forward to the release of Linux Kernel 5.0 in the coming weeks, we can enjoy another venerable open source technology reaching the 5.0 milestone: the Bash shell utility. The GNU Project has launched the public version 5.0 of GNU/Linux’s default command language interpreter.

Through several years of hard work and many iterations, my fellow teachers and I were eventually able to develop a comprehensive, school-wide project-based learning model, where students worked in collaborative teams on projects that made real connections between required curriculum and community-based applications. Doing so gave these students the ability to develop skills they can use for a lifetime...

Redmine is one of the most popular open source project management and issue tracking software tools. It is cross-platform and cross-database and built on top of the Ruby on Rails framework. In this tutorial we will cover the steps needed to install and configure the latest version of Redmine on an CentOS 7 server using MariaDB as a database back-end and Passenger + Nginx as a Ruby application server.

There are still people in the technology field today that consider Linux a "hobbiest" toy. Can a serious student get through 6 years of college with just Linux? Some can, and some cannot. We'll take a look at the latter here.

In this article, we will be learning about the various data types in MySQL and also how data modeling is done. I am assuming you have a working instance of MySQL on your computer. If not, you can read the step by step installation instructions.

The increasing number of devices that connect over-the-air to the internet over-the-air and the wide availability of WiFi access points provide many opportunities for attackers to exploit users. By tricking users to connect to rogue access points, hackers gain full control over the users' network connection, which allows them to sniff and alter traffic, redirect users to malicious sites, and launch other attacks over the network.. read more

Redmine is a free, open source and web-based project management web application that allows users to manage multiple projects and associated subprojects. In this tutorial, we will install Redmine with Apache web server on Ubuntu 18.04 LTS.

Load average is a measurement of the amount of work versus free CPU cycles available on a system processor. In this article I’ll define the term, demonstrate how Linux calculates this value, then provide insight into how to interpret system load.

Thanks to open source software, we can now take control over and modify the behavior of almost every component in an IT system. We can modify everything from the networking stack in the kernel all the way down to web server code in user space to make improvements or implement new features. The final hurdle to having complete control over our hardware and software stack is the physical network hardware. These devices are usually built from the open source tools we love, but they are presented as black boxes that can't easily be modified by network operators. read more

Deepin 15.9 was released today two months after the Deepin 15.8 update, adding yet another layer of improvements and performance optimizations, but also a couple of new features for fans of this Linux-based operating system.

A Bash function is essentially a set of commands that can be called numerous times. The purpose of a function is to help you make your bash scripts more readable, and to avoid writing the same code over and over again.

New Zealand's economy is dependent on agriculture, a sector that is highly sensitive to climate change. This makes it critical to develop analysis capabilities to assess its impact and investigate possible mitigation and adaptation options. That analysis can be done with tools such as agricultural systems models. In simple terms, it involves creating a model to quantify how a specific crop behaves under certain conditions then simulating altering a few variables to see how that behavior changes. read more

With ffsend you can easily and securely share files from the command line, by making use of a Send, a Firefox test pilot project. Firefox Send is a file sharing experiment by Mozilla, which allows sending encrypted files to other users.

Even if you're already familiar with the printf command, if you got your information via "man printf" you may be missing a couple of useful features that are provided by bash's built-in version of the standard printf(1) command.

In the world of modern enterprise technologies, open source software has firmly established itself as one of the biggest forces to reckon with. After all, some of the biggest technology developments have emerged because of the open source movement. read more

This detailed guide will give you enough information to start using Emacs, and enough extra to make you want more.

This is the latest in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For this article, we’ll look at Krusader, a free and open source graphical file manager.

There seems to be a mad rush at the beginning of every year to find ways to be more productive. New Year's resolutions, the itch to start the year off right, and of course, an "out with the old, in with the new" attitude all contribute to this. And the usual round of recommendations is heavily biased towards closed source and proprietary software. It doesn't have to be that way. Here's the fourth of my picks for 19 new (or new-to-you) open source tools to help you be more productive in 2019. read more

There are quite a few interesting things that you can do with "zip" commands on Linux other than compress and uncompress files. Here are some other zip options and how they can help.

The more digital we become, the less human we remain.
