  • ABYSS - the genesis of a fully free streaming software package used at LibrePlanet

    As an FSF intern during the winter and spring of 2016, I had the opportunity to be around FSF's tech team during LibrePlanet preparation, and we spent a lot of time making the streaming and recording work as well as possible so that people who were not in each talk could still watch it (all the recordings are already up on

    Each room at the LibrePlanet conference has a streaming set-up staffed by a volunteer. There are many skilled volunteers, but we need to minimize the risk of failed recordings due to over-complex or error-prone software systems. So, in order to improve streaming we decided to quickly develop a GPLv3 program to provide a seamless interface for an audio and/or video streaming console.

    As a newcomer to the free software community, I have been looking for ways to contribute by coding. The huge amount of projects in progress have overwhelmed me a bit. So, when it was proposed to create a piece of software to be used directly by the community at the conference, I was full of joy about beginning a project.

  • Network Disaggregation: Opening The Last Black Box

    The third “black box” was the network operating system (NOS). Once proprietary systems that were supplied only by the big networking vendors, these NOS products are now offered by software vendors like Big Switch, Cumulus, and Pica8. The NOS must comply with three key component areas within the device: the CPU and the motherboard (or the BSP), “U-Boot” (or universal boot loader), and the ASIC’s APIs. All three collectively need to be matched to the network OS in order to port a NOS onto that same piece of metal. This is why so-called white-box SDN vendors either sell the complete switch and OS solution or provide a list of pre-qualified switches so you can directly buy the hardware.

  • What is open source software? [Ed: weak article on facts]

    Some people prefer open source software because they see it to be more secure in terms of virus attacks and stable as a support platform for other software. Others may prefer open source because they genuinely cannot afford to buy proprietary software. But as you explore any form of software, please remember they are all vulnerable in their own ways and need protection from attacks. Good Luck!

And we all know that the days of analyzing just your own company data are long gone. Piping in more data is essential these days.

  • FreeBSD Is Pursuing A Compatibility Layer To Make It Easier To Run Linux DRM Drivers

    While for years developers working on FreeBSD have been porting DRM/KMS driver changes from the Linux kernel over to their kernel, they have trailed greatly behind the mainline Linux kernel driver state due to the amount of changes they have been making to the driver when re-basing it against a new Linux kernel release. Now they are pursuing a new approach of using a compatibility layer where they hope to be able to more closely follow the upstream Linux DRM/KMS drivers.

  • The fork? Node.js: Code showdown re-opens Open Source wounds

    Open source software rarely receives the kind of attention that the press lavishes on the latest hot new thing blessed by Silicon Valley venture capitalists. Yet these projects are the foundations of the web world.

    Without open source there would be no Slack, no Medium, no Github. Nor would there be Google, Facebook, or much of anything else.

    Without open source projects like Apache, Nginx, OpenSSL, OpenSSH and others (to say nothing of GNU/Linux, which does get some attention), the latest hot new thing would likely not exist. More fundamentally, the web as we know it would not exist.

  • Growing a contributor base in modern open source

    The focus of Node.js over the last year has been to increase the number of contributors working on the project. Node.js has seen sustained 100% year-over-year user growth for several years, but the number of contributors was, at one point, actually on the decline.

    After a year+ of community building and iteration we're now healthier than ever. The project has reorganized itself divided into many components and sits at 400 members. Across most repos, which now make up the project as a whole, we're seeing that ~50% of the contributors in a given month are new to that repository. That means our conversion of users into contributors is six times higher than the growth of our user community. Contributors are essential to the health and longevity of an open source project.

Evolution or Revolution? The Impact of Open Source on Communication Providers

Filed under

The march toward open source is rapidly turning into an all-out race, with research projects and applications extending to new industry sectors, including communication providers. What started out in the software realm has moved into the hardware space, bringing with it significant changes for providers and vendors alike. Most recently, the Open Compute Project (OCP) and its spin-offs, including the Telecom Infra Project (TIP), have not only reinforced this shift toward open source, but have accelerated the trend.

  • Drupal and Alexa: The Next Big Thing?

    DrupalCon is underway in New Orleans, Louisiana, and it kicked off with the always energetic keynote from Drupal project founder, Dries Buytaert. While these regular keynotes, known as "DriesNotes" in the Drupal Community, tend to focus on the state of the Drupal project, with updates on the development cycle and community interests, there is frequently also a particularly inspiring look toward the future. This year, Dries wowed the audience with a quick demo of a Drupal site communicating with an Amazon Echo to provide a personalized shopping experience via Echo's conversational interface. And perhaps most interesting was Buytaert's take on conversational interfaces as the next big shake-up for developers and content creators, much like mobile interfaces changed the way we approach web development in the recent past.

  • What Does DevOps 2.0 Look Like?

    In 2008, Patrick Debois laid the foundations for DevOps at an Agile conference in Toronto. He was trying to come up with a solution for the inherent conflicts between developers and system admins. Both disciplines seemed to be at odds: developers wanted to release software more frequently, but system admins wanted to ensure stability, performance, and scalability. While this conflict isn’t necessarily black and white, it highlighted the need for developers and system admins to no longer consider themselves as mutually exclusive roles, but rather as cross-functional partners.

    I got some problems during the last weeks of Google Summer of Code which made me deal with some challenges. One of these challenges was caused by a HD physical problem. I haven’t made a backup of some work and had to rework again in some parts of my code. As I already knew how to proceed, it was faster than the first time. I had to understand how the device loading process is made in Calamares to load a preview of the new LVM VG during its creation in Partition Page. I need to list it as a new storage device in this page and deal with the revert process. I’ve implemented some basic fixes and tried to improve it.
