The availability of fairly affordable CNC machines and replacement controller boards with fast microcontrollers and network connectivity makes it a great time to get into CNC. Many options are available including basing your CNC on a 3040 from China or using open source software and open hardware to run the show...

In this week's edition of our open source news roundup, we take a look at 3D-printed lattice for cell culture, open source materials for college courses, and more! Open source news roundup for June 12-18, 2016 read more

This is my October 2007 "SuitWatch" newsletter for Linux Journal. I believe it's the first place I floated the "giant zero" metaphor for the Internet, which I've made a bit of a thing about since then.

PostgreSQL (most people call it Postgres) is an advanced object-relational database management system (ORDBMS). Postgres is an open source database server with more than 18 years of active development which makes Postgres the best choice for enterprise-class applications. In this tutorial, I will show you how to install Postgres on your own server with OpenSUSE Leap as operating system. Then I will install phpPgAdmin so we can manage our Postgres database from the web browser.

A new version of Git was released this week, bringing a number of improvements that will be a welcome sight to software developers.

Aaeon has added extended temperature support to seven embedded boards, including a “PICO-BT01” Pico-ITX SBC with Bay Trail CPUs and optional add-on boards. Aaeon has added wider temperature range options to a number of its embedded SBCs and COMs. Most of these boards originally came out before LinuxGizmos (now HackerBoards) was launched in early 2013.

Shortly after the Fedora 24 release, you can upgrade to the newest Fedora Workstation using the built-in Software app (gnome-software). The Software app has always provided the ability to process updates. But to upgrade to the latest Fedora — for example, Fedora 22 to... Continue Reading →

Many of us aspire to contribute to open source projects, but only a few are able to actually do it. We're all perennially short of time, and we're always prioritizing. But how do the people who actually contribute to projects find time? What is it that they know and others don't? read more

In order to still be able to find out what the majority of the community considers the right approach towards our Vision, we set up an online survey, hoping that this would make it easier for people to voice their opinion in an easy, anonymous way.

Canonical's Snappy package manager is taking its first steps outside the Ubuntu world. As of now, you can install it on Arch, Debian, Fedora and several other popular distros.

Canonical and Ubuntu founder Mark Shuttleworth said in an interview that he hadn't planned on an announcement about Ubuntu's new Snap app package format. But then in a matter of a few months, developers from multiple Linux distributions and companies announced they would use Snap as a universal Linux package format.

Verizon Labs is building some impressive projects around Apache Mesos and relies on a lot of open source software for functionality: operating systems, networking, provisioning, monitoring, and administration. Open source software is popular at Verizon Labs because it gives them the flexibility and the functionality to do what they want to do, without fighting vendor restrictions.

In this article, we continue our look at processes and go back to school for a moment, where we’ll pick up some of the basics that will help us increase our knowledge later.

Octave, the equivalent software to Matlab in Linux, has a number of functions and commands that allow the acquisition, recording, playback and digital processing of audio signals for entertainment applications, research, medical, or any other science areas. In this tutorial, we will use Octave V4.0.0 in Ubuntu and will start reading from audio files through writing and playing signals to emulate sounds used in a wide range of activities.

Koschei is a continuous integration service for RPM packages. It helps developers fix bugs as fast as possible. It tracks package dependency changes in Rawhide, the bleeding-edge, development version of Fedora. Packages whose dependencies change too much are rebuilt. Koschei logs... Continue Reading →

I'm a member of two non-profits in my city. One of them is a sporting league, the other a community initiative to save a bit of land from commercial development. Both organizations are member-run. No one is paid to participate and external funding is minimal; in fact volunteers pay membership dues each year. Neither has a "CEO" or "board chair" position (other than those members arbitrarily give). These small non-profits barely have web presences—let alone a connection to the open movement. read more

IBM Linux on Power Chief Engineer, Jeff Scheel, answers your questions about little endian and Linux on IBM Power Systems in this FAQ

Aren't we supposed to be living in a paperless world by now? I can't be the only person who imagined the office of the future, free from the confines of the eight and a half by eleven sheet (or A4, for my international friends), would have long since arrived. Instead, we've managed to land in an intermediate state of not paperless, but less paper. It could be worse. read more

Monohm has relaunched its disc-shaped, open source “Runcible” mobile device, which runs an Android-based OS on a Snapdragon 410, and has a 2.5-inch display. The Runcible received a lot of media attention when it was originally announced running Firefox OS in Feb. 2015. But it also left a lot of questions. Was the rounded, disc-shaped […]

Being a 3D artist used to mean that you were exclusively a digital artist—you worked in a virtual environment with intangible materials. The result of your work was destined to be seen only in print or on screens. Even in a virtual reality (VR) environment, the result is, at best, an illusionary representation of your three-dimensional work. 3D printing has changed that. read more
