In this edition of our open source news roundup, we take a look three governments turning to open source, open sourcing driverless car safety practices, a school district developing an open source curriculum, and more.

Real-Time Linux (RT Linux) has been a staple at Embedded Linux Conferences for years... as RT prepares to be fully integrated into the mainline kernel, a wider circle of developers should pay attention. In particular, Linux device driver authors will need to ensure that their drivers play nice with RT-enabled kernels.

Once upon a time the idea of upgrading the Linux kernel sent fear through the hearts of many a user. Back then, the process of upgrading the kernel involved a lot of steps and even more time. Now, installing a new kernel can be easily handled...

In my day job, I spend a lot of time wrangling data from various sources into human-readable information. While a lot of the time this just takes the form of a spreadsheet or some type of chart or other data visualization, there are other times when it makes sense to present the data instead in a written format. But a pet peeve of mine is copying and pasting. If you’re moving data from its source to a standardized template, you shouldn’t be copying and pasting either. It’s error-prone, and honestly, it’s not a good use of your time. read more

MongoDB is a NoSQL database that offers a high performance, high availability, and automatic scaling enterprise database. Data is stored in a "document" structure in JSON format (in MongoDB called BSON). MongoDB was first introduced in 2009 and is currently developed by the company MongoDB Inc. This tutorial shows the installation and configuration of MongoDB on Ubuntu 18.04 LTS.

Fedora now features a curated set of third-party software repositories, containing software not traditionally available Fedora, like Google Chrome and Steam. By default, Fedora only includes free and open source software. However, with the introduction of these curated third-party repositories, users can opt-in to enabling selected extra sources. Some software in these optional sources is […]

A big problem with supervised machine learning is the need for huge amounts of labeled data. It's a big problem especially if you don't have the labeled data—and even in a world awash with big data, most of us don't.

In a recent Opensource.com article, Lewis Cowles introduced the find command. find is one of the more powerful and flexible command-line programs in the daily toolbox, so it's worth spending a little more time on it. At a minimum, find takes a path to find things.

Depending on who you ask, serverless is either the same thing as, or conceptually related to, Function-as-a-service.

News briefs for April 26, 2018.

Ubuntu will still live on as a desktop operating system, but that's not where Canonical sees it as having its greatest potential. Even in 2018, if you ask most people what they know about Ubuntu, they'll tell you it's a desktop Linux. Oh, but there's so, so much more to Canonical's Ubuntu than that, and in its latest long-term support (LTS) release, Ubuntu 18.04 LTS, that really shows up.

Kontron has unveiled its first product based on Intel’s 8th Gen “Coffee Lake” processors. The […]

Ruby on Rails is a useful framework for quickly building line-of-business applications. But as our applications grow, we face scaling challenges. There are a variety of tools we can use—but adding different technologies to our applications increases complexity. This article explores how to use the Redis in-memory data structure store as a multi-purpose tool to solve different problems. read more

R is the de facto statistical package in the Open Source world. It's also quickly becoming the default data-analysis tool in many scientific disciplines. In this article, I look at one of the available GUIs: RStudio. RStudio is a commercial program, with a free community version, available for Linux...

Kata Containers is a new open source project licensed under Apache 2.0 and governed by the OpenStack Foundation that combines the speed of containers with the security of virtual machines. Kata Containers will be featured in a number of upcoming sessions at OpenStack Summit and KubeCon EU. Can't make it to either of those events? We've brought you answers to three of the top questions we hear from users. read more

This tutorial shows the installation of an Ubuntu 18.04 minimal server in detail with many screenshots. The purpose of the guide is to show the basic installation of Ubuntu 18.04 LTS that can be used as basis for our other Ubuntu tutorials here at howtoforge like our perfect server guides.

CPU utilization is the metric everyone uses to measure a processor's performance. But %CPU is a misleading measure of how busy your processor really is, says Brendan Gregg, senior performance architect at Netflix, in what he calls a "five-minute public service announcement," at the 16th annual Southern California Linux Expo (SCALE). read more

Blender is a complex piece of software that is capable of producing extremely high-quality visuals for all manner of visual art purposes, from video games to product visualization. Of course, that power needs to be wielded by a controlled hand. Otherwise, you'll end up with a mush of digital geometry that makes no sense at all. read more

Technology is at an interesting crossroads, where Linux rules the server landscape but Microsoft rules the enterprise desktop. Office 365, Skype for Business, Microsoft Teams, OneDrive, Outlook... the list goes on of Microsoft software and services that dominate the enterprise workspace. What if you could replace that proprietary software with free and open source applications and make them work with an Office 365 backend you have no choice but to use? Buckle up, because that is exactly what we are going to do with Pidgin, an open source replacement for Skype. read more

At Embedded Linux Conference 2018, NI’s Julia Cartwright told device driver authors how to ensure their drivers will run without a hitch on Real-Time Linux. Although Real-Time Linux (RT Linux) has been a staple at Embedded Linux Conferences for years — here’s a story on the RT presentations in 2007 ....
