This tutorial shows you how to install a MongoDB Sharded Cluster on CentOS 7. Sharding is a MongoDB process to store data-set across different machines. It allows you to perform a horizontal scale of data and to partition all data across independent instances.

Around this time every year, our minds turn to copyright. Or maybe they turn more to copyright. After all, open source works because of copyright law. As you may already know, copyright laws give the authors of works the exclusive right to copy (among other things) their work. These rights attach as soon as the work is fixed in a tangible medium (written down, saved to disk, etc.). So the rights that open source licenses grant rely on copyright law. read more

Most of the Linux commands you encounter do not depend on other operations for users to unlock their full potential, but there exists a small subset of command line tool which you can say are useless when used independently, but become a must-have or must-know when used with other command line operations. One such tool is yes, and in this tutorial, we will discuss this command with some easy to understand examples.

All the major Linux distributions have now released their Intel chip meltdown patches. But, someone must retune all those servers to get their performance up to speed and replace network devices and servers running up-to-date Linux distros.

Akademy is the KDE Community conference. The 2018 edition is from Saturday 11th to Friday 17th August in Vienna, Austria. If you are working on topics relevant to KDE or Qt, this is your chance to present your work and ideas at the Conference. The days for talks are Saturday and Sunday, 11th and 12th. The rest of the week will be BoFs, unconference sessions and workshops.

When last we met, we learned that the Linux console supports multimedia. Yes, really! You can enjoy music, movies, photos, and even read PDF files without being in an X session with MPlayer, fbi, and fbgs. And, as a bonus, you can enjoy a Matrix-style screensaver for the console, CMatrix.

Canonical, the company that makes Linux distro Ubuntu, has re-released its Meltdown update for Ubuntu 16.04 LTS Xenial users after the first attempt tripped up machines.

The PiTalk is an RPi phone add-on board. The Gemini PDA is a clamshell re-spin of the Psion. Eelo is a privacy-oriented phone ROM. Samsung is planning to load Ubuntu desktops on Galaxy phones. They all want to reinvent the Linux phone concept.

Algorithms are everywhere in our world, and so is bias. From social media news feeds to streaming service recommendations to online shopping, computer algorithms—specifically, machine learning algorithms—have permeated our day-to-day world. As for bias, we need only examine the 2016 American election to understand how deeply—both implicitly and explicitly—it permeates our society as well. What’s often overlooked, however, is the intersection between these two: bias in computer algorithms themselves. read more

The technical savvy and inventive energy of young programmers is alive and well.T o learn more about what college students think when they hear "open source," I surveyed several college students who are members of the same professional computer science organization I belong to.

There may be no question in the open source community which elicits quite the same passion in people's responses as "What's your favorite Linux distribution?" There are all sorts of reasons people take their pick. It could be based on familiarity, on the UI, on performance, on package availability, on stability, on support, or thousands of other factors. Every year, just once, we let you chime in and tell us your favorite.

As upstream Glibc is working on deprecating libcrypt for its eventual removal from the codebase, Fedora developers are looking at using libxcrypt for their hashing/encoding crypto library.

Pzizz is an Android app that generates a custom "nap narrative" that helps ease you off to dreamland and wakes you up when it's over. I was very skeptical about how restful a 20-minute forced nap could be, and at first, I doubted I'd fall asleep at all. Thankfully, I was very wrong.

Artila’s “Matrix-713” mobile IoT gateway runs Linux on a Cortex-A5 ATSAMA5D35, and provides Fast and Gigabit Ethernet, 2x CAN, 2x mini-PCIe, GPS, and an IMU, and supports -20 to 80°C temperatures. Artila’s Mobile IoT Gateway Matrix-713 follows a similarly headless Matrix-710 embedded computer announced last May, which also runs Linux 4.9 ......

You might be familiar with the expression: So many tools, so little time. In order to try to save you some time, I've outlined some of my favorite tools that help agile teams work better. If you are an agilist, chances are you're aware of similar tools, but I'm specifically narrowing down the list to tools that appeal to open source enthusiasts. read more

This tutorial shows how to install ISPConfig 3.1 on a CentOS 7.4 (64Bit) server. ISPConfig 3 is a web hosting control panel that allows you to configure the following services through a web browser: Apache web server, Postfix mail server, MySQL, BIND nameserver, PureFTPd, SpamAssassin, ClamAV, Mailman, and many more.

Recently I wanted to create an Arduino-based low-power Internet of Things (IoT) device for makers, with built-in sensors that could be used to deliver sensor data from any location to the cloud, and potentially control connected devices such as thermostats, lights, door locks, and other home automation products. Along the way, I learned that creating a new IoT device, from idea to prototype to final product, is not as simple as I thought it would be, and there was no "ready-to-go" development device to start with. read more
