Quick Roundup

The origin and evolution of FreeDOS

Filed under
OS

Over the years, developers have shared with me how they use FreeDOS to run embedded systems. My all-time favorite example is a developer who used FreeDOS to power a pinball machine. FreeDOS ran an application that controlled the board, tallied the score, and updated the back display. I don't know exactly how it was built, but one way such a system could work is to have every bumper register a "key" on a keyboard bus and the application simply read from that input. I thought it was cool.

People sometimes forget about legacy software, but it pops up in unexpected places. I used to be campus CIO of a small university, and once a faculty member brought in some floppy disks with old research data on them. The data wasn't stored in plaintext files, rather as DOS application data. None of our modern systems would read the old data files, so we booted a spare PC with FreeDOS, downloaded a shareware DOS program that could read the application data, and exported the data to plaintext.

U.S. makes renewable energy software open source

Filed under
OSS

As a longtime proponent of open source solar photovoltaic development, I am happy that the U.S. National Renewable Energy Lab (NREL) has shared all the source code for System Advisor Model (SAM), its most powerful renewable energy economic analysis software.

SAM is now SAM Open Source. It is a performance and financial model designed to help make decisions about renewable energy. This is perfect timing, as the costs of solar have dropped so far that the levelized cost of electricity for solar power is less than what you are probably paying for electricity from your utility.

  • 20 Most Promising Open Source Solution Providers - 2017

    Open source has become an imperative part of every developer’s arsenal. The potential to gather assistance from the community and the capacity to link into a range of systems and solutions make open source incredibly powerful. As open source software becomes ubiquitous, and used by the vast majority of enterprises throughout the world, 2017 is all set for vendors of application delivery controller (ADC) to start providing improved and tighter integration packages for various open source projects, especially surrounding ADC-generated telemetry. Companies have been extensively using their analytics and machine learning capabilities for quite some time to identify actionable patterns from the collected data. With the rising demand for business intelligence, this year is foreseen to be the year of information superiority with businesses, leveraging data as a key differentiator. In the past couple of years, containers have been emerging as an imminent trend. As the business focus starkly shifts on rightsizing of resources, containers are expected to become a common phenomenon, giving businesses the ability to leverage highly portable assets and make the move into micro services much simpler. Adjacently, automation has become essential now. Mostly intensified by DevOps adoption, the automation of software delivery and infrastructure changes have freed developers to spend more time creating and less time worrying about infrastructure.

  • DevOps pros and open source: Culturally connected

    Like chocolate and peanut butter, DevOps and open source are two great tastes that taste great together. For many DevOps pros, it's the perfect cultural and technical match.

  • Interoperability: A Case For Open Source - GC@PCI Commentary

    He continues: “An open source model allows companies to see the assumptions behind the calculation and lowers the cost of entry into the cat modeling business. More importantly, the standardized and interoperable hazard, vulnerability and financial modules included in a true open source model facilitate the collaboration of data from insurers, reinsurers, entrepreneurs, scientists, computer programmers and individuals, all of which may result in a new generation of cat models.”

  • DevOps Skills Are Key to Collaboration within Organizations

    DevOps is one of the most highly sought skills employers are seeking to fill among 57 percent of respondents in the 2017 Open Source Jobs Report, from Dice and The Linux Foundation. Specifically, firms are looking for developers (73 percent) and DevOps engineers (60 percent).

  • Linux Kernel Community Enforcement Statement
  • Linux Kernel Gets An "Enforcement Statement" To Deal With Copyright Trolls

    Greg Kroah-Hartman on the behalf of the Linux Foundation Technical Advisory Board has today announced the Linux Kernel Community Enforcement Statement. This statement is designed to better fend off copyright trolls.

    Among the copyright troll concerns is how a Netfilter developer has been trying to enforce his personal copyright claims against companies for "in secret and for large sums of money by threatening or engaging in litigation."

  • An enforcement clarification from the kernel community

    The Linux Foundation's Technical Advisory board, in response to concerns about exploitative license enforcement around the kernel, has put together this patch adding a document to the kernel describing its view of license enforcement. This document has been signed or acknowledged by a long list of kernel developers. In particular, it seeks to reduce the effect of the "GPLv2 death penalty" by stating that a violator's license to the software will be reinstated upon a timely return to compliance.

GNOME: LVFS and Epiphany

  • Richard Hughes: Shaking the tin for LVFS: Asking for donations!

    Nearly 100 million files are downloaded from the LVFS every month, the majority being metadata to know what updates are available. Although each metadata file is very small it still adds up to over 1TB in transfered bytes per month. Amazon has kindly given the LVFS a 2000 USD per year open source grant which more than covers the hosting costs and any test EC2 instances. I really appreciate the donation from Amazon as it allows us to continue to grow, both with the number of Linux clients connecting every hour, and with the number of firmware files hosted. Before the grant sometimes Red Hat would pay the bandwidth bill, and other times it was just paid out my own pocket, so the grant does mean a lot to me. Amazon seemed very friendly towards this kind of open source shared infrastructure, so kudos to them for that.

    At the moment the secure part of the LVFS is hosted in a dedicated Scaleway instance, so any additional donations would be spent on paying this small bill and perhaps more importantly buying some (2nd hand?) hardware to include as part of our release-time QA checks.

  • Epiphany 3.28 Development Kicks Off With Safe Browsing, Better Flatpak Handling

    Epiphany 3.27.1 was released a short time ago as the first development release of this web-browser for the GNOME 3.28 cycle.

    For being early in the development cycle there is already a fair number of improvements with Epiphany 3.27.1. Some of the highlights include Google Safe Browsing support, a new address bar dropdown powered by libdazzle, and improvements to the Flatpak support.

  • Safe Browsing in Epiphany

    I am pleased to announce that Epiphany users will now benefit from a safe browsing support which is capable to detect and alert users whenever they are visiting a potential malicious website. This feature will be shipped in GNOME 3.28, but those who don’t wish to wait that long can go ahead and build Epiphany from master to benefit from it.

    The safe browsing support is enabled by default in Epiphany, but you can always disable it from the preferences dialog by toggling the checkbox under General -> Web Content -> Try to block dangerous websites.

Conservancy Applauds Linux Community's Promotion of Principled Copyleft Enforcement

Filed under
GNU
Legal

Software Freedom Conservancy congratulates the Linux community for taking steps today to promote principled, community-minded copyleft enforcement by publishing the Linux Kernel Enforcement Statement. The Statement includes an additional permission under Linux's license, the GNU General Public License (GPL) version 2 (GPLv2). The additional permission, to which copyright holders may voluntarily opt-in, changes the license of their copyrights to allow reliance on the copyright license termination provisions from the GNU General Public License version 3 (GPLv3) for some cases 1.

Conservancy also commends the Linux community's Statement for reaffirming that legal action should be last resort for resolving a GPL violation, and for inviting noncompliant companies who work their way back into compliance to become active participants in the community. By bringing clarity to GPLv2 enforcement efforts, companies can adopt software with the assurance that these parties will work in a reasonable, community-centric way to resolve compliance issues.

Servers: Containers, 'Cloud', Microservices, and Hyperledger

  • How to Choose a Linux Container Image
    A comparison of Linux container images talks about the best-practices in choosing an image. Architecture, security and performance are among the factors, while commercial users would also look for support options. A Linux container allows separate management of kernel space and user space components by utilizing cgroups and namespaces, which are resource and process isolation mechanisms. Solaris and BSD also have abstractions similar to Linux containers but the article's focus is on the latter only. The host running the container has the operating system kernel and a set of libraries and tools required to run containers. The container image, on the other hand, has the libraries, interpreters and application code required to run the application that is being distributed in the container. These depend on underlying system libraries. This is true for interpreted languages too as the interpreters themselves are written in low level languages.
  • The Four Pillars of Cloud-Native Operations
    As organizations shift their application strategies to embrace the cloud-native world, the purpose of the cloud transitions from saving money to delivering and managing applications. Platforms such as Cloud Foundry, Kubernetes, and Docker redefine the possibilities for application environments that utilize the cloud. It’s time for us as operations professionals to rethink how we approach our jobs in this new world. We should be asking, how do our organizations take advantage of cloud-native as a new mode of application delivery?
  • How to align your team around microservices
    Microservices have been a focus across the open source world for several years now. Although open source technologies such as Docker, Kubernetes, Prometheus, and Swarm make it easier than ever for organizations to adopt microservice architectures, getting your team on the same page about microservices remains a difficult challenge. For a profession that stresses the importance of naming things well, we've done ourselves a disservice with microservices. The problem is that that there is nothing inherently "micro" about microservices. Some can be small, but size is relative and there's no standard measurement unit across organizations. A "small" service at one company might be 1 million lines of code, but far fewer at another organization.

Canonical on Path to IPO as Ubuntu Unity Linux Desktop Gets Ditched

In October 2010, Mark Shuttleworth, founder of the Ubuntu open-source operating system and CEO of Canonical, announced his grand plan to build a converged Linux desktop that would work on mobile devices, desktops and even TVs. He called the effort "Unity" and poured significant financial resources into it. Seven years later, the Unity dream is dead. On Oct. 19, Ubuntu 17.10 was released as the first Ubuntu Linux version since 2010 that didn't use Unity as the default Linux desktop. In a video interview with eWEEK, Shuttleworth details the rationale behind his decision to cancel Unity and why he has now put his company on the path toward an initial public offering (IPO). Because Ubuntu has moved into the mainstream in a bunch of areas, including the cloud, he said some of the things his company had been doing were never going to be commercially sustainable.
