  • Brief on Behalf of Amicus Curiae Open Source Hardware Association in Curver Luxembourg, SARL v. Home Expressions Inc., No. 18-2214 (Fed. Cir.)

    Curver Luxembourg, SARL v. Home Expressions Inc. is a case of first impression for the Court of Appeals for the Federal Circuit. The question on appeal is whether a design patent’s scope is tied to the article of manufacture disclosed in the patent.

    In this amicus brief, the Open Source Hardware Association (“OSHWA”) explains the potential effects on open source hardware development, and design practice generally, of untethering design patent protection from the article of manufacture disclosed in the patent. A large percentage of open-source hardware combines both ornamental and functional elements, and industrial design routinely involves applying design concepts from disparate fields in novel ways. To engage in this practice, open-source hardware designers need to know the universe of available source material and its limits. Further, understanding the licensing requirements of open-source hardware begins with understanding how the elements that make up that hardware may or may not be protected by existing law. Accordingly, while many creators of open-source hardware do not seek patent protection for their own creations, an understandable scope of design patent protection is nonetheless essential to their ability to collaborate with other innovators and innovate lawfully.

    The brief argues that the District Court in the case—and every district court that has considered the issue—correctly anchored the patented design to the article of manufacture when construing the patent. The brief explains that anchoring the patented design to the disclosed article of manufacture is the best approach, for several reasons. Connecting the patented design to the disclosed article of manufacture calibrates the scope of design patent protection to the patentee’s contribution over the prior art. It avoids encumbering the novel and nonobvious application of prior designs to new articles of manufacture, a fundamental and inventive practice of industrial design. It aligns the scope of design patent protection with its purpose: encouraging the inventive application of a design to an article of manufacture. This balances protection for innovative designs with later innovators’ interest in developing future designs. Finally, anchoring the patented design to the disclosed article of manufacture helps fulfill design patent law’s notice function by clarifying the scope of protection.

  • EPA Rule Will Make Its Custom Code Open Source By Default

    The Environmental Protection Agency is getting ready to default to making all its custom code open source, finally meeting an Office of Management and Budget policy instituted during the last administration.

    The EPA will publish a notice Friday in the Federal Register soliciting public comment on a new open-source policy that will be added to the agency’s acquisition regulations. The clause—which will be added to all EPA contracts that include the use of open-source software or the development of custom code that may or may not be shared widely—will require contractors to provide the agency with all “underlying source code, license file, related files, build instructions, software user’s guides, automated test suites and other associated documentation as applicable,” according to the notice.

  • Environmental Protection Agency Acquisition Regulation (EPAAR); Open Source Software

    A Proposed Rule by the Environmental Protection Agency on 10/18/2019

    [...]

    The EPA is writing a new EPAAR clause to address open source software requirements at EPA, so that the EPA can share custom-developed code as open source code developed under its procurements, in accordance with Office of Management and Budget's (OMB) Memorandum M-16-21, Federal Source Code Policy: Achieving Efficiency, Transparency, and Innovation through Reusable and Open Source Software. In meeting the requirements of Memorandum M-16-21 the EPA will be providing an enterprise code inventory indicating if the new code (source code or code) was custom-developed for, or by, the agency; or if the code is available for Federal reuse; or if the code is available publicly as open source code; or if the code cannot be made available due to specific exceptions.

To space and beyond with open source

Filed under
OSS

The Cambridge Dictionary defines curiosity as "an eager wish to know or learn about something." It's curiosity that fuels our drive to acquire knowledge about outer space, but what drives our curiosity, our "eager wish," in the first place?

I believe that our curiosity is driven by the desire to escape the unpleasant feeling of uncertainty that is triggered by acknowledging our lack of knowledge. The intrinsic reward that comes from escaping uncertainty pushes us to find a correct (or at least a less wrong) answer to whatever question is at hand.

If we want space discovery to advance at a faster pace, we need more people to become aware of the rewards that are waiting for them when they make the effort and discover answers for their questions about the universe. Space discovery is admittedly not an easy task, because finding correct answers requires following rigorous methods on a long-term scale.

Luckily, open source initiatives are emerging that make it easier for people to get started exploring and enjoying the beauty of outer space.

Apache Rya matures open source triple store database

Filed under
OSS

The open source Apache Rya database effort is continuing to move forward as it reaches a new level of project maturity and acceptance.

Rya (pronounced "ree-uh") is an RDF (resource description framework) triple store database. The project started at the U.S. government's Laboratory for Telecommunication Sciences with an initial research paper published in 2012.

The project joined the Apache Software Foundation (ASF) in 2015 as an incubated project, and in September 2019 achieved what is known as Top-Level Project status. The Top-Level status is an indication and validation of the project's maturity, code quality and community. The ASF is home to Hadoop, Spark and other widely used database and data management programs.

How I built and maintain Cantata, an open source music player

Interviews
OSS

This is the third in a series of conversations with developers who build and maintain open source music players. Craig Drummond is the developer and maintainer of Cantata, an open source music player that acts as a frontend (client) to the Music Player Daemon (MPD) music server. I have two small headless computers at home configured as music servers—one connected to our stereo in our living room, one in my upstairs office. I first ran into Cantata while I was looking for a way to control these servers, and wow, it is one impressive piece of work.

I was interested in learning more about Cantata, so I was grateful when Craig agreed to do this interview (which has been lightly edited for length and clarity). Without further ado, let’s chat with Craig.

In 2019, multiple open source companies changed course—is it the right move?

Filed under
OSS

Free and open source software enables the world as we know it in 2019. From Web servers to kiosks to the big data algorithms mining your Facebook feed, nearly every computer system you interact with runs, at least in part, on free software. And in the larger tech industry, free software has given rise to a galaxy of startups and enabled the largest software acquisition in the history of the world.

Free software is a gift, a gift that made the world as we know it possible. And from the start, it seemed like an astounding gift to give. So astounding in fact that it initially made businesses unaccustomed to this kind of generosity uncomfortable. These companies weren't unwilling to use free software, it was simply too radical and by extension too political. It had to be renamed: "open source."

Once that happened, open source software took over the world.

Recently, though, there's been a disturbance in the open source force. Within the last year, companies like Redis Labs, MongoDB, and Confluent all changed their software licenses, moving away from open source licenses to more restrictive terms that limit what can be done with the software, making it no longer open source software.

  • FOSSCOMM 2019 aftermath

    FOSSCOMM (Free and Open Source Software Communities Meeting) is a Greek conference aiming at free-software and open-source enthusiasts, developers, and communities. This year was held at Lamia from October 11 to October 13.

    It is a tradition for me to attend to this conference. Usually I have presentations and of course booths to inform the attendees about the projects I represent.

    This year the structure of the conference was kind of different. Usually the conference starts on Friday with "beer event". Now it started with registration and a presentation. Personally I made my plan to leave from Thessaloniki by bus. It took me about 4 hours on the road. So when I arrived, I went to my hotel and then waited for Pantelis to go to the University and setup our booths.

  • Empowering Generations of Digital Natives

    Technology is changing faster each year. Digital literacy can vary between ages but there are lots of ways different generations can work together and empower each as digital citizens.

    No matter whether you’re a parent or caregiver, teacher or mentor, it’s hard to know the best way to teach younger generations the skills needed to be an excellent digital citizen. If you’re not confident about your own tech skills, you may wonder how you can help younger generations become savvy digital citizens. But using technology responsibly is about more than just technical skills. By collaborating across generations, you can also strengthen all your family members’ skills, and offer a shared understanding of what the internet can provide and how to use it to help your neighborhoods and wider society.

  • How to Verify Smart Contracts on Etherscan

    You have your smart contract written, tested, and deployed. However, customers aren’t willing to do business with you unless they know the contract’s source code. After all, it could be set up in a way that’s not in their interest.

    Thankfully, Etherscan offers a neat tool that allows you to verify smart contracts so interested parties can see the source code and verify for themselves that everything is as it should be.

    While the process is simple, there are intricacies that might cause problems, especially to people not very familiar with Ethereum and the Solidity programming language.

  • Ethical Open Source: Is the world ready?

    Given its incredible popularity in the marketplace, there is no question that many software developers (and their respective companies) today see great value in using software that is subject to open source licenses. Users focus on the advantages to be had by gaining access, usually at no or minimal charge, to the software’s source code and to the thriving open source community supporting such projects.

    Powered by a worldwide community supporting the code base, open source code is generally perceived to be more reliable, robust and flexible than so-called proprietary software, with increased transparency leading to better code stability, faster bug fixes, and more frequent updates and enhancements.

    Historically the question of ethics and open source software (OSS) has mainly focussed on the goal of obtaining and guaranteeing certain “software freedoms,” namely the freedom to use, study, share and modify the software (as exemplified by the Free Software Definition and copyleft licenses such as the GPL family), and to ensure that derivative works were distributed under the same license terms to end “predatory vendor lock-in.”

  • Confidential Computing Consortium Establishes Formation with Founding Members and Open Governance Structure

    The Confidential Computing Consortium, a Linux Foundation project and community dedicated to defining and accelerating the adoption of confidential computing, today announced the formalization of its organization with founding premiere members Alibaba, Arm, Google Cloud, Huawei, Intel, Microsoft and Red Hat. General members include Baidu, ByteDance, decentriq, Fortanix, Kindite, Oasis Labs, Swisscom, Tencent and VMware.

    The intent to form the Confidential Computing Consortium was announced at Open Source Summit in San Diego earlier this year. The organization aims to address data in use, enabling encrypted data to be processed in memory without exposing it to the rest of the system, reducing exposure to sensitive data and providing greater control and transparency for users. This is among the very first industry-wide initiatives to address data in use, as current security approaches largely focus on data at rest or data in transit. The focus of the Confidential Computing Consortium is especially important as companies move more of their workloads to span multiple environments, from on premises to public cloud and to the edge.

deepin Linux 20 looks incredible

I recently sold my MacBook Pro for a few reasons, but probably most importantly, macOS just wasn't wowing me anymore. While Apple's desktop operating system is good for basic users, it is far too limited for the more hardcore. Ultimately, I found my productivity was negatively impacted by macOS -- my workflow with Windows 10 and various Linux distributions was simply better. Of course, with all of that said, macOS is much prettier than Windows 10 -- even Microsoft would confess to that. But is it more attractive than desktop Linux distributions? Well, that depends on the desktop environment. While there are plenty of beautiful DEs and launchers for Linux, only one really surpasses macOS in the looks department -- deepin. Read more

New TenFourFox and Mozilla Firefox Team News

  • TenFourFox FPR16 SPR1 available

    TenFourFox Feature Parity Release "16.1" (SPR 1) is now available for testing (downloads, hashes, release notes). As noted, this is a pure security update and there are no user-facing changes; the big under-the-hood change of those is that we are now pulling entirely from 68ESR, including locale data, certificate roots and so forth. There is also a small update to the ATSUI font blacklist. Assuming no issues, it will go live Monday evening Pacific time as usual.

  • AMD Zen 2 Improvements For LLVM Have Been Held Up For Months By Code Review

    Back in February for LLVM Clang 9.0 was the initial AMD Zen 2 "znver2" enablement, but like the GCC support at the time it was the very basics. With time GCC picked up Zen 2 scheduler improvements and other work while sadly in the case of LLVM the improvements are still pending. Back in August, AMD's Ganesh Gopalasubramanian sent out the znver2 scheduler model for LLVM for Zen 2 CPUs but a focus on the EPYC 7002 "Rome" processors. "There are few improvements with respect to execution units, latencies and throughput when compared with znver1. The tests that were present for znver1 for llvm-mca tool were replicated. The latencies, execution units, timeline and throughput information are updated for znver2."

    This tutorial covers the following topic – Python Add lists. It describes various ways to join/concatenate/add lists in Python. For example – simply appending elements of one list to the tail of the other in a for loop, or using +/* operators, list comprehension, extend(), and itertools.chain() methods. Most of these techniques use built-in constructs in Python. However, the one, itertools.chain() is a method defined in the itertools module. You must also see which of these ways is more suitable in your scenario. After going through this post, you can evaluate their performance in case of large lists.
