In an entertaining keynote presentation at Open Source Summit in Los Angeles, Dan Lyons, author of Disrupted: My Misadventure in the Start Up Bubble, related his experience working at a tech startup and explained how that experience changed his mind about open source.

Several years ago, I wrote an article on using Elmer to solve complicated physics problems. Elmer has progressed quite a bit since then, so I thought it would be worth taking a fresh look at this simulation software.

We've all been there. You're starting a new job, and you don't even know where the bathroom is, much less all the tools and processes necessary to get that job done. Onboarding in an open organization can be even trickier because of its unstructured environment and open culture. It may be up to you to define your role, and priorities can change quickly. Finding an "onboarding buddy" (or "onboarding peer") can make the transition into your job much less painful. read more

Artist's impression of what Plasma Mobilewould look like on the Librem 5. "This was the plan all along", said Todd Weaver during a conference call we held with him last week. He was referring to building a free, open, and privacy-respecting smartphone...

In this tutorial, we’ll learn how to install and configure DHCP server in Debian 9. DHCP or Dynamic Host Configuration Protocol is a protocol used in networks through which a system can automatically obtain the network settings at boot time.

Laird unveiled a Linux-based “Open Platform” for telematics and in-car connectivity with WiFi, BLE, and NFC, and optional GPS/Glonass, LTE, and 802.11p. Linux is finding its way into car systems that move beyond in-vehicle infotainment (IVI) and into telematics and connectivity. On the low end, we’ve seen products like the recent, Raspberry Pi Zero W […]

The world is fundamentally generative, as it is created by physical, biological, and chemical processes. But it isn't comprised of clean mathematical lines; rather, it is a struggle between mathematical patterns and entropy. Generative art reflects both aspects of reality, offering a unique perspective on the world. read more

Open-source software can profitably bring rivals together.

Computers were first invented to do math, and they do it really well. But it didn't take long for users to repurpose their futuristic calculators into fancy, dynamic typewriters. Now human-readable text drives computing, so it's important to choose the right format for the text you write. read more

Keeping up with new technology can be a challenge. There may be no place where this is truer than in the world of enterprise cloud software. It seems every day that passes introduces a new tool or application that could soon be a part of your organization's technology stack.

Linus Torvalds, creator of Linux, likes to be comfortable in his home office, so he spends his workdays in his bathrobe. Life is good when you're the world's most influential developer.

Once upon a time, I wanted to be an evolutionary biologist. To make a long story short, I had a change of heart and dropped out of my PhD program to pursue a career in computer science. I'm now a senior software engineer at Red Hat, where I work on a variety of machine learning and data science projects (you can read more about my journey on my blog). read more

My day job pays me on the 15th and last day of every month, unless those days land on a weekend, in which case I get paid the Friday before. With those rules, creating a Google Calendar event is shockingly difficult. In fact, it's not possible to create a recurring event with those rules using Google's GUI scheduling tool.
