Linux and Open Source Hardware for IoT

Filed under
Linux
OSS

Most of the new 21 open source software projects for IoT that we examined last week listed Linux hacker boards as their prime development platforms. This week, we’ll look at open source and developer-friendly Linux hardware for building Internet of Things devices, from simple microcontroller-based technology to Linux-based boards.

In recent years, it’s become hard to find an embedded board that isn’t marketing with the IoT label. Yet, the overused term is best suited for boards with low prices, small footprints, low power consumption, and support for wireless communications and industrial interfaces. Camera support is useful for some IoT applications, but high-end multimedia is usually counterproductive to attributes like low cost and power consumption.

  • What does it mean to change company culture?

    Tools are specific concrete things that a culture has decided is a way to improve a process. Buckminster Fuller has a great quote about tools and thinking: "If you want to teach people a new way of thinking, don't bother trying to teach them. Instead, give them a tool, the use of which will lead to new ways of thinking." In particular, DevOps tools can provide folks new ways to look at things—like delivering code into a production environment, for example. But there's lots of examples where a new tool doesn't influence the thinking of the people who use it, so things don't change.

    Google says its algorithm can correctly caption a photograph with nearly 94 percent accuracy.

    The company says the improvements come in the third version of its system named Inception, with the score coming from a standardized auto-caption test named ImageNet. It reports the first version scored 89.6 percent, the second 91.8 percent and the new one 93.9 percent.

  • Contributing to Open Source Projects Not Just For the Experts

    XDA has long been a proponent of open source development, and we’ve seen it flourish over the years. In fact, it’s one of the main reasons our community has grown as fast as it has over these past 13 years, with Android’s core being the driving force. Many people desire to be part of open source and contribute but often don’t know how they can, whether because they think they lack the skills or they just don’t have the time.

    Why you still need a (permissive) license

    Norms aren’t enough if the underlying legal system might allow an early contributor to later wield the law as a threat. That’s why the best practice in the data space is to use something like the Creative Commons public domain grant (CC-Zero) to set a clear, reliable, permissive baseline, and then use norms to add flexible requirements on top of that. This uses law to provide reliability and predictability, and then uses norms to address concerns about fairness, free-riding, and effectiveness. CC-Zero still isn’t perfect; most notably it has to try to be both a grant and a license to deal with different international rules around grants.

  • NIST Releases New 'Family' of Standardized Genomes

    With the addition of four new reference materials (RMs) to a growing collection of “measuring sticks” for gene sequencing, the National Institute of Standards and Technology (NIST) can now provide laboratories with even more capability to accurately “map” DNA for genetic testing, medical diagnoses and future customized drug therapies. The new tools feature sequenced genes from individuals in two genetically diverse groups, Asians and Ashkenazic Jews; a father-mother-child trio set from Ashkenazic Jews; and four microbes commonly used in research.

    NIST issued the world’s first genome reference material (NIST RM 8398)—detailing the genetic makeup for a woman with European ancestry—in May 2015. Together, all five RMs serve as a collection of well-characterized, whole genome standards that can tell a laboratory how well its DNA sequencing processes are working by measuring the performance of the equipment, chemistry and data analysis involved.

OSS

School's back in session, and kids love the creative arts. One of my favorite open source creative tools is Audacity, the open source audio recorder and editor. Students love manipulating digital sound with Audacity: making podcasts, learning languages, recording interviews, and recording and mixing music.

I use it to record podcasts for students to provide instructions about classroom procedures and tests. Foreign language students use Audacity to record and play back their lessons. Students can download music and other types of audio tracks for sharing and re-use from Creative Commons and Wikimedia, and dub their own voices onto music tracks, the sounds of birds chirping, whales and dolphins in their natural habitats, and more.

GE, Bosch and open source could bring more IoT tools

Filed under
OSS

The two companies, both big players in industrial IoT, said they will establish a core IoT software stack based on open-source software. They plan to integrate parts of GE's Predix operating system with the Bosch IoT Suite in ways that will make complementary software services from each available on the other.

The work will take place in several existing open-source projects under the Eclipse Foundation. These projects are creating code for things like messaging, user authentication, access control and device descriptions. Through the Eclipse projects, other vendors also will be able to create software services that are compatible with Predix and Bosch IoT Suite, said Greg Petroff, executive director of platform evangelism at GE Software.

Exactly What Is OpenStack? Red Hat's Rich Bowen Explains

Filed under
Red Hat
OSS

You've probably heard of OpenStack. It's in the tech news a lot, and it's an important open source project. But what exactly is it, and what is it for? Rich Bowen of Red Hat provided a high-level view of OpenStack as a software project, an open source foundation, and a community of organizations in his talk at LinuxCon North America.

OpenStack is a software stack that went from small to industry darling at warp speed. It has three major components: The compute service runs the virtual machines (VMs), and it has a networking service and a storage service, plus a dashboard to run everything. OpenStack is only six years old, and was born as a solution devised by Rackspace and NASA to solve a specific problem.

One of the great strengths of open source is that it provides opportunities for everyone. Regardless of background, age, gender, race, ethnicity, nationality, sexual orientation or religion, everyone can benefit from and contribute to some of the most important technologies ever developed.

Yet we know that many groups remain underrepresented in the open source community, which is why The Linux Foundation engages in efforts such as providing diversity scholarships for our training and events and sponsoring organizations such as Women Who Code, Code.org, Blacks in Technology, All Star Code and more.

How to throw a tarball over the wall

Filed under
OSS

It costs a lot of money to open source a mature piece of commercial software, even if all you are doing is "throwing a tarball over the wall." That's why companies abandoning software they no longer care about so rarely make it open source, and those abandoning open source projects rarely move them to new homes that benefit others.

If all you have thought about is the eventual outcome, you may be surprised how expensive it is to get there.

The tool has gone through a number of iterations over the years, extending its capabilities to assess the infrastructure requirements of ever-more virtual desktops along the way while also keeping up with changes to VMware's Horizon and Citrix's XenDesktop.

But Leibovici says he's now sufficiently busy that “Unfortunately I find myself without time to maintain the VDI calculator, therefore I decided that the best outcome would be to open-source the app and let the community drive maintenance and innovation.”

Hence its publication under an Apache 2.0 licence here on GitHub.

  • Minijail: Running Untrusted Programs Safely by Jorge Lucangeli Obes, Google
  • Minijail: Google’s Tool To Safely Run Untrusted Programs
    Google’s Minijail sandboxing tool could be used by developers and sysadmins to run untrusted programs safely for debugging and security checks, according to Google Software Engineer Jorge Lucangeli Obes, who spoke last month at the Linux Security Summit. Obes is the platform security lead for Brillo, Google's Android-based operating system for Internet-connected devices. Minijail was designed for sandboxing on Chrome OS and Android, to handle “anything that the Linux kernels grew.” Obes shared that Google teams use it on the server side, for build farms, for fuzzing, and pretty much everywhere. Since “essentially one bug separates you and any random attacker,” Google wanted to create a reliable means to swiftly identify problems with privileges and exploits in app development and easily enable developers to “do the right thing.” The tool is designed to assist admins who struggle with deciding what permissions their software actually needs, and developers who are vexed with trying to second guess which environment the software is going to run in. In both cases, sandboxing and privilege dropping tends to be a hit or miss affair. Even when developers use the privilege dropping mechanisms provided by the Linux kernel, sometimes things go awry due to numerous pitfalls along that path. One common example Obes cited was trying to ride a switch user function that will drop-root and then forgetting to check the result of the situation relief, or setuid function, afterwards.
  • Intel and Cloudera Give Apache an Open Source Data/Security Tool
    For the past year, we've taken note of the many Big Data projects that the Apache Software Foundation has been elevating to Top-Level Status. The organization incubates more than 350 open source projects and initiatives, and has squarely turned its focus to Big Data and developer-focused tools in recent months. As Apache moves Big Data projects to Top-Level Status, they gain valuable community support. Recently, the foundation announced that Apache Kudu has graduated from the Apache Incubator to become a Top-Level Project (TLP). Kudu is an open source columnar storage engine built for the Apache Hadoop ecosystem designed to enable flexible, high-performance analytic pipelines. And, Apache Twill has graduated as well. Twill is an abstraction over Apache Hadoop YARN that reduces the complexity of developing distributed Hadoop applications, allowing developers to focus more on their application logic. In another Apache-related Big Data move, Cloudera and Intel have announced that they've contributed a new open-source project to the Apache Software Foundation targeted at using Big Data analytics and machine learning for cybersecurity.

  • Open standards default at Slovenia supreme court
    The use of open ICT standards is an IT requirement at Slovenia’s Supreme Court, responsible for the IT support of the entire court system in the country. The Supreme Court’s IT department has a strong preference for the development of modular, reusable software solutions. This strategy provides agility and flexibility, says Bojan Muršec, director of IT. The focus on open standards frees up the IT department to concentrate on the business, Muršec says. The IT department takes the modular approach serious: the first reusable module ever developed by the court - a court documents dispatch and delivery system - is re-used by all IT systems across the courts. “Making everything reusable prevents creation of silos in the organisation”, the IT director says. A positive side effect of the IT strategy is that the court uses mostly open source software solutions. This in turn helps to keep IT costs down, says the IT director, who estimates that the court saves EUR 400 to 500 thousand per year on licence fees: “The cost of proprietary licences always goes up.”
  • Why there is no CSS4 - explaining CSS Levels
    We had CSS1, and CSS2. We even had CSS2.1 and we then moved onto CSS3 – or did we? This post is a quick explanation of how CSS is versioned today. CSS versions 1 and 2 were monolithic specifications. All of CSS was included in one massive document. Selectors, positioning, colour – it was all in there. The problem with monolithic specifications is that in order to finish the spec, every component part also has to be finished. As CSS has grown in complexity, and new features are added, it doesn’t make sense to draw a line at which all work is stopped on all parts of CSS in order to declare that CSS version finished. Therefore, after CSS2.1 all the things that had been part of the 2.1 specification were broken down into modules. As the new CSS modules included all that had gone before plus any new features, they all came into being at Level 3. Hence CSS3, and people like me who understood CSS as a single specification referred to the group of Level 3 modules as “CSS3”.

  • Don't Hide DRM in a Security Update
    Over 10,000 of you have joined EFF in calling on HP to make amends for its self-destructing printers in the past few days. Looks like we got the company’s attention: today, HP posted a response on its blog. Apparently recognizing that its customers are more likely to see an update that limits interoperability as a bug than as a feature, HP says that it will issue an optional firmware update rolling back the changes that it had made. We’re very glad to see HP making this step. But a number of questions remain. First, we’d like to know what HP’s plans are for informing users about the optional firmware update. Right now, the vast majority of people who use the affected printers likely do not know why their printers lost functionality, nor do they know that it’s possible to restore it. All of those customers should be able to use their printers free of artificial restrictions, not just the relatively few who have been closely following this story.
