I believe that WordPress has a place in every PK-12 school. Most teachers are looking for ways to quickly engage parents with news from the classroom, and while many use social media, WordPress provides a powerful alternative. A simple classroom blog that's easily accessible to all is a great way to improve communication. read more

Calendar technology is not encrypted by default. That means any individual or provider between you and your calendar notifications can read and potentially store that information. Data deserves to be owned and secured by users through the use of open source paired with end-to-end encryption. read more

Ubiquity and Democracy are the two words that best describe the open source PostgreSQL (Postgres) database management system. And, much like Linux, both are great examples of “open source at its best”.

Memcached is a general-purpose memory-caching system. This means it is designed to save (or cache) answers to questions that take a long time to compute or retrieve and are likely to be asked again. A common use case is to accelerate the use of a database: for example, if we expect to need the list of "names of all people who are on team X" repeatedly, we might put this data in Memcached rather than run a SQL query each time. (Note: Memcached is occasionally referred to as "memcache." We will stick to the full name throughout this article.) read more

Garz & Fricke’s “Tanaro” SBC runs Linux or Android on an i.MX8M Mini with 2x Ethernet, mini-PCIe, LVDS with optional touchscreens, and isolated CAN and serial ports. Garz & Fricke announced a “coming up” Tanaro (or Tanaro Core) SBC that features NXP’s quad -A53, 1.8GHz i.MX8M Mini Quad, the faster, but HD-only cousin to the […]

Many people are becoming involved with open source software development by contributing to projects on GitHub. Many of them use GitHub's graphical user interface (GUI), especially those who are new to the command-line interface (CLI). But what if you prefer working on the command line? read more

Magento is one of the most popular open-source e-commerce platforms that allows you to set up e-commerce websites and online stores in minutes. In this tutorial, we will show you how to install Magento on CentOS 8 with Let's Encrypt free SSL.

VPC (Virtual Private Cloud) falls under - Network and Content Delivery - service in AWS (Amazon Web Services). VPC provides us logically a virtual private, isolated cloud. In this article, we will see how to create a VPC using the Wizard as this is the simplest way to start with.

I've written before about what a community manager does, and if you ask ten community managers, you'll get 12 different answers. Mostly, though, you do what the community needs for you to do at any given moment. And a lot of it can be repetitive. Back when I was a sysadmin, I had a rule: if I had to do something three times, I'd try to automate it. And, of course, these days, with awesome tools like Ansible, there's a whole science to that. read more

Meld is one of my essential tools for working with code and data files. It's a graphical diff tool, so if you've ever used the diff command and struggled to make sense of the output, Meld is here to help. Here is a brilliant description from the project's website: read more

‘The world around us may be going through strange times, but so far kernel development looks normal’ says Penguin emperor. Linus Torvalds has released a new release candidate of the Linux kernel – version 5.6 rc7 - and added a little COVID-19 commentary.…

The Raspberry Pi makes for a useful and inexpensive home server for lots of things. I most often use the Raspberry Pi as a print server to share a laser printer with other devices in our home or as a personal file server to store copies of projects and other data.

Cockpit is a very useful utility allowing you to manage a compatible system over the network from the comfort of a web browser (See the list of supported web browsers and Linux distributions).

Recently, we published an article about why developers prefer to code at night. Author Matt Shealy highlighted the many benefits of nocturnal programming including the quiet time and space for creative thinking.

Community building is table stakes in the success of any open source project. Even outside of open source, community is considered a competitive advantage for businesses in many industries—from retail, to gaming, to fitness. (For a deeper dive, see "When community becomes your competitive advantage" in the Harvard Business Review.)

Everyone knows they shouldn't take shortcuts, especially in their work, and yet everyone does. Sometimes it doesn't matter, but when it comes to code development, though, it definitely does. As any experienced programmer knows, building your code the quick and dirty way soon leads to problems down the line. These issues might not be disastrous, but they incur a small penalty every time you want to develop your code further.

With ventilators in dangerously short supply during the COVID-19 pandemic, a number of DIY groups have begun working on open source designs that could be made at home.

Examining files from the command-line is generally an easy thing to do. You just run the command you want, followed by a list of files to be examined. Dealing with binary files, however, is more complicated. These files are often packaged up into archives, tarballs, or other packaging formats. The run-on-binaries script provides a convenient way to run a command on a collection of files, regardless of how they are packaged. The invocation of the script is quite simple: read more

We not only don't know how many people have coronavirus in the US, but we also don't even know how many have been tested. So, researchers, using open-source tools, are digging out the real numbers for us.
