  • Unikernels, Docker, and Why You Should Care

    Docker's recent acquisition of Unikernel Systems has sent pulses racing in the microservice world. At the same time, many people have no clue what to make of it, so here's a quick explanation of why this move is a good thing.

    Although you may not be involved in building or maintaining microservice-based software, you certainly use it. Many popular Web sites and services are powered by microservices, such as Netflix, eBay and PayPal. Microservice architectures lend themselves to cloud computing and "scale on demand", so you're sure to see more of it in the future.

  • Docker gets minimalist with plan to migrate images to Alpine Linux

    Rumor has it that Docker Inc., the company behind Docker containers, is planning to switch from Ubuntu to the lightweight Alpine Linux OS as the host environment for Docker images.

The Money In Open-Source Software

Filed under
OSS

It’s no secret that open-source technology — once the province of radicals, hippies and granola eaters — has gone mainstream. According to industry estimates, more than 180 young companies that give away their software raised roughly $3.2 billion in financing from 2011 to 2014.

Even major enterprise-IT vendors are relying on open-source for critical business functions today. It’s a big turnaround from the days when former Microsoft CEO Steve Ballmer famously called the open-source Linux operating system “a cancer” (and obviously a threat to Windows).

S.F. Officials Push for Adoption of Pioneering Open-Source Voting System

Filed under
OSS

Just over a year ago the Board of Supervisors passed a resolution that required the city to study open-source voting. Last November, the Department of Elections approved a plan asking the mayor and the board to start and fund the work. Arntz said the agency plans to submit a budget request to Mayor Ed Lee at the end of the month, proposing spending $2.3 million toward an open-source system.

4 Truths About Working on a Community Project Inside an Open Source Company

Filed under
OSS

I’ve worked at SUSE for just a hair over two years now. Before that time I had never seen the inner workings of an “Open Source Company”. Not in any real, in-depth way.

Like many Free Software and Linux enthusiasts, I had always been curious how things operated within companies like SUSE, Red Hat and Canonical. Companies that support, organize and drive such a significant amount of activity in the Free and Open Source world. To me, they seemed somewhat mysterious. What really motivated them? How did they operate? What was it like to be a Linux user who actually worked in a Linux-focused company?

  • IT sector: Promote open source, bring enabling provisions for Start-up India

    The IT/ITeS sector, one of the largest contributors to exports in the country, has played a vital role in shaping the overall growth story of India. In view of the challenging business environment, the sector has significant expectations from the ensuing Union Budget 2016 on the tax and policy initiatives front.

  • S.F. Officials Push for Adoption of Pioneering Open-Source Voting System [Ed: Beware Microsoft]

    San Francisco could launch a major makeover of its voting systems this year, an effort that supporters say will lead to cheaper, more transparent elections in the city.

    On Tuesday, Supervisor Scott Wiener will call for a Board of Supervisors hearing into the city’s efforts to adopt a voting system that would use off-the-shelf hardware and open-source software. Elections officials, politicians and voter-participation activists have all touted such publicly owned balloting systems as cheaper and more trustworthy than using products supplied by private vendors.

    “We want to set a trend here and around the country toward more open and transparent voting systems,” Wiener said in an interview.

  • Open Source Assignments for Non-Programming Classes

    I’ve been flirting with the idea of asking students in my Educational Game Design module to make their projects “open source”.

    I am wary of the way non-computer scientists use the term “open source”. I often hear people mistakenly refer to free software as “open source”, when its code is not at all open source. I have also heard people in open education talk about how we can learn from open source, but I always felt cautious about this because the contexts are usually different.

Building a culture of more pluggable open source

Filed under
OSS

If there is one word that often percolates conversations hailing the benefits of open source, it is choice. We often celebrate many of the 800+ Linux distributions, the countless desktops, applications, frameworks, and more. Choice, it would seem, is a good thing.

Interestingly, choice is also an emotive thing.

A new frontier for open source: Linux will power our robotic future

Linux
OSS

"You know, with windows versus Linux, Windows got there first by a long shot. It was the entrenched party. So Linux is the scrappy upstart. In the case of robotics, open source got there first. The community grew up doing things the open source way. There was actually a period in the mid-2000s where Microsoft put a lot of effort into its Windows-based Robotics Developer Studio. It had really good features, but it's never taken off. So yeah, I think robotics are proving to be a different situation than what happened with personal computing."

Long live Linux. Long live ROS. Long live open source.

An open source fix leads to a new career in IT

Filed under
OSS

Today at InterWorx, I write software for Linux for web hosting companies. I got my RHCSA last year, and I'm currently studying for the RHCE. I'd love to say that I got into open source and Linux for philosophical reasons, but to be honest it was just because it let me get stuff done. If it wasn't for Linux and other open source software, I never would have been able to fix that problem all those years ago. With that one opportunity (and a lot of work!), I was able to start a path to a whole new career.

4 open source tools for Linux system monitoring

Filed under
OSS

This article discusses some of the interactive command line interface (CLI) tools that are provided with or which can be easily installed on Red Hat related distributions including Red Hat Enterprise Linux, Fedora, CentOS, and other derivative distributions. Although there are GUI tools available and they offer good information, the CLI tools provide all of the same information and they are always usable because many servers do not have a GUI interface but all Linux systems have a command line interface.

This article concentrates on the tools that I typically use. If I did not cover your favorite tool, please forgive me and let us all know what tools you use and why in the comments section.

An introduction to Joplin, an open source Evernote alternative

Joplin is an open source cross-platform note-taking and to-do application. It can handle a large number of notes, organized into notebooks, and can synchronize them across multiple devices. The notes can be edited in Markdown, either from within the app or with your own text editor, and each application has an option to render Markdown with formatting, images, URLs, and more. Any number of files, such as images and PDFs, can be attached to a note, and notes can also be tagged. I started developing Joplin when Evernote changed its pricing model and because I wanted my 4,000+ notes to be stored in a more open format, free of any proprietary solution. To that end, I have developed three Joplin applications, all under the MIT License: for desktop (Windows, MacOS, and Linux), for mobile (Android and iOS), and for the terminal (Windows, MacOS, and Linux). All the applications have similar user interfaces and can synchronize with each other. They are based on open standards and technologies including SQLite and JavaScript for the backend, and Terminal Kit (Node.js), Electron, and React Native for the three front ends. Read more

Open Source OS Still supporting 32-bit Architecture and Why it’s Important

One after the other, Linux distributions are dropping 32-bit support. Or, to be accurate, they drop support for the Intel x86 32-bit architecture (IA-32). Indeed, computers based on x86_64 hardware (IA-64) are superior in every way to their 32-bits counterpart: they are more powerful, run faster, are more compact, and more energy efficient. Not mentioning their price has considerably decreased in just a few years. If you have the opportunity to switch to 64 bits, do it. But, to quote a mail I received recently from Peter Tribble, author of Tribblix: “[… ] in the developed world we assume that we can replace things; in some parts of the developing world older IA-32 systems are still the norm, with 64-bit being rare.” Read more
