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

Checked C lands on Github The zombie bugs in programs and libraries at the heart of the Internet's infrastructure often have the C programming language in common.…

Lifelong tinkerer and gadget enthusiast Mark Geddes was so frustrated with the lack of practical, visual Arduino guides for teaching his ten-year-old that he wrote his own book on the topic.

Thanks to open source software, Powering Potential and the Raspberry Pi Foundation are able to bring computers and a library of digital education content to rural schools in the East African nation of Tanzania. read more

Could the transactional mechanism that drives Canonical’s IoT-focused Snappy Ubuntu Core help unify Linux and save it from fragmentation? This week, Canonical announced that the lightweight Snappy Ubuntu Core’s “snap” mechanism, which two months ago was extended to all Ubuntu users in Ubuntu 16.04, can also work with other Linux distributions. Snap could emerge as […]

In a post earlier this month, I mentioned the importance of building a network of people who can help us identify and recruit potential Board level contributors and senior advisors. We are also currently working to expand both the Mozilla Foundation and Mozilla Corporation Boards.

It’s impressive that  IBM was founded more than a century ago with decades of research, technologies, and products behind it. But even more impressive is that the company continues to evolve and embrace emerging technologies. It’s done so, in part, due to its continued involvement with Linux and open source through The Linux Foundation.

Xilinx unveiled a dual-core “CG” version of its Cortex-A53/FPGA Zynq UltraScale+ MPSoC, and Mentor Graphics announced Android 5.1 and Linux support. Back in Feb. 2015, Xilinx announced its next generation Zynq UltraScale+ MPSoC (multiprocessor system-on-chip) follow-on to its popular Zynq 7000 hybrid ARM/FPGA system-on-chips.

Flow is a mental state of intense focus and it's a state that your brain can enter while hula hooping and programming. I'm going to explore how we can mix these two things to enhance skill and learning.

In this tutorial, I will show you how to build your own file sync and share server with seafile on openSUSE Leap 42.1. Seafile is a free file hosting software with a functionally like Dropbox or Google Drive that can be installed on your own server.

Using auditd to monitor some preset events is already quite useful, but where it comes into its own is when you customize it to monitor whatever you want.

Confession: I am a total book nerd! There are always a ton of book recommendations given while attending a conference, and this year at OSCON was no different. Instead of spreading my book recommendations out and including them in my OSCON event reports, I collected them all in here in one list. Enjoy and let me know if you have read and liked (or didn't) any of these! Or, feel free to leave a comment suggesting a great book for us to read. read more

Chris Prather never metaphor he didn't like. That's what he tells developers, at any rate. And on stage at SouthEast LinuxFest in Charlotte, NC, Prather explained how a deep understanding of metaphor—and the critical role it plays in cognitive function—can improve an open source software developer's work. He delivered his presentation, "I Never Metaphor I Didn't Like: How Cognitive Linguistics Can Help You Be A (More) Bad-ass Developer," last Friday. read more

Do you have some old hardware collecting dust in the basement, attic, or garage? Don’t let it go to waste just because it’s not powerful enough to run modern operating systems. Linux can breathe new life into such machines.
