  • Codeplay Launches Open-Source 'SYCL Academy' To Learn This Increasingly Popular Standard

    While SYCL has been around for five years as a Khronos standard providing a single-source C++ programming model for exploiting OpenCL, it has yet to reach its prime but demand for it is picking up with Intel working to upstream their SYCL back-end in LLVM, SYCL becoming part of their programming model with oneAPI and Xe Graphics, and other vendors also jumping on the SYCL bandwagon. Codeplay has now provided an open-source SYCL learning code for those interested in this higher-level alternative to straight OpenCL programming.

  • Open-Source Build and Test Tool Bazel Reaches 1.0

    Derived from Google's internal build tool Blaze, Bazel is a build and test tool that offers a human-readable definition language and is particularly aimed at large, multi-language, multi-repositories projects. Originally open-sourced in 2015, Bazel has now reached 1.0.

    One of the major implications of reaching version 1.0 for Bazel is the promise of greater stability and backward-compatibility guarantees. This has been a historical pain point for Bazel users, who often found themselves in the situation of having to rewrite part of their build rules due to frequent breaking changes in Bazel or its ecosystem. Accordingly, the Bazel team has committed to following semantic versioning for future Bazel releases, meaning only major versions will be allowed to include breaking changes. Furthermore, the team committed to maintaining a minimum stability window of three months between major versions.

  • DevOps Deeper Dive: DevOps Accelerates Open Source Innovation Pace

    That rate of innovation has increased dramatically in the last few years. However, much of that innovation would not have been possible if large swaths of the open source community hadn’t been able to employ best DevOps practices to collaborate, said CloudBees CEO Sacha Labourey.

    [...]

    None of this shift has been lost on IT vendors. As the demand for proprietary code slackened, many found it profitable to offer support services for open source software. The more there is to consume, the more the support services contracts grew. Now every vendor from IBM to small IT services providers such as Fairwinds has launched open source projects that help drive demand for IT services expertise.

    “There’s pain around integrating a lot of disparate open source projects,” said Robert Brennan, director of open source software for Fairwinds. “Organizations may be getting software for free, but there’s usually not a lot of help around.”

    Now almost every IT vendor in the world is making software engineers available to work on open source projects. All that talent focused on open source projects has led to the development of new platforms such as Jenkins, GitHub, Kubernetes and, more recently, a raft of smaller projects. With the rise of containers and cloud-native applications, open source software projects are entering another era that will see many of those same software engineers leveraging DevOps practices more broadly to drive even more innovative projects at increasingly faster rates.

  • Find your next developer from open source communities

    Meanwhile, demand for data scientists is rising as companies seek AI-based solutions to stay competitive. Demand is reflected in salary offers. Companies competing to hire and retain data experts are offering on average more than US$100,000, making it one of the most highly paid professions in the States.

    For companies lacking the budget to hire or train in-house staff to fill the role, they may find themselves struggling with maintaining technological infrastructure or moving forward with plans for digitization.

    Therefore, open source learning and further development of communities could be the solution to this gap.

    An IBM grant to support open source communities such as Girls Who Code, a non-profit organization offering coding lessons for women in the US, is a step forward to filling in a shortage of software developers.

  • TriggerMesh Aims to Orchestrate Serverless Computing on Kubernetes

    TriggerMesh has raised $3 million in additional funding to advance the integration of Kubernetes clusters with serverless computing frameworks. In addition, the company announced it has made available open source integrations between its namesake orchestration for serverless computing frameworks and IBM MQ event sources, VMware vSphere event sources and the Microsoft Azure Event Hub channel controller. The TriggerMesh platform provides access to a cloud bus to facilitate application flow orchestration and the consumption of events emanating from any data center application or cloud source. It is designed to trigger serverless functions using a declarative application programming interface (APIs) and a set of tools for defining event flows and functions. Company co-founder Mark Hindle says that as IT organizations embrace modern application development platforms, a transition is occurring in terms of how stateless and stateful applications are constructed. Initially, organizations limited container use to building stateless applications. Now, however, many stateless applications are being built using functions that access serverless computing frameworks. [...] Unfortunately, serverless computing standards, de facto or otherwise, are a work in progress. Google and its allies are making a case for a set of open source Knative middleware that integrates Kubernetes clusters with any number of open serverless computing frameworks. However, the adoption of open serverless computing frameworks is still relatively nascent. The most widely used serverless computing framework is the proprietary AWS Lambda service. However, the adoption of rival frameworks is expected to increase substantially in 2020—a report published this week by Allied Market Research predicts the global serverless architecture market will reach $22 billion by 2025, representing a compound annual growth rate of 27.8% between 2018 and 2025.

  • Blocking spammers in https://progress.opensuse.org

    But our ticket system is not really planned to become a ticket system: we run Redmine, which originally is intended to be a project management software. The ability to create issues (or tickets, as we call them) in the system by sending an Email was not really intended in the beginning. So the ability to detect and mark Spam Emails as such simply does not exist. Even worse: every Email results in a user, that get's created automatically, to allow us to send out an Email to this person as answer to his ticket. All of this is not really problematic: you learn to deal with it. But with over 14,000 "users" in the database (and over 17,000 real tickets), the system started to become slow. So we invested a bit of our time and looked into the user list. Good for us: most of the Spammers seen to have special days to submit their stuff. And even more interesting: they do it at the same time from multiple accounts!

  • A forum for Flathub

    Flathub is primarily built around GitHub, where applications manifests and infrastructure code live. Unsurprisingly, it turns out that code hosting platform isn't exactly a go-to place for the community to connect, even if one slaps a discussion label on an issue. Timezones and personal commitments mean that IRC is also not an ideal platform for discussion, and Flathub does not have a mailing list for discussion and announcements.

  • F31-20200122 Updated Live isos released

This set of updated isos will save considerable amounts of updates after install. ((for new installs.)(New installs of Workstation have 1GB+ of updates)). A huge thank you goes out to irc nicks dowdle, Southern-Gentleman for testing these iso.

  • CircleCI automates Continuous Delivery to multiple clouds

    Modern software development is fast, continuous, and automated. Today, by research company Statista's count, 88% of organizations are using Agile methods and Continuous Integration/Continuous Delivery (CI/CD). Yet there remains one major stumbling block: Moving a freshly minted program from a CI pipeline to delivery to a cloud or other service provider. That's where DevOps company CircleCI comes in with a new suite of orb integrations with 20 partners such as Amazon Web Services (AWS), Google Cloud, Salesforce, and others. These enable developers to automate remote deployments in minutes from their CI/CD pipeline. [...] CircleCI's partners are happy with the expansion of orbs. Rayn Veerubhotla, Google Cloud's Director of Hybrid Partnerships, said: "Google Cloud Run helps developers run stateless containers and focus on writing high-value code, without worrying about the underlying infrastructure. By launching these new tools, CircleCI is enabling developers to further streamline and simplify their experience on Cloud Run, ultimately helping businesses bring new services and products to their customers more quickly." The same is true of all the clouds that orbs are now supporting. If you find your CI/CD team slowed down by final step deployment issues, you should check this new offering out. It could save you time, work, and money.

  • Dfinity launches an open-source platform aimed at the social networking giants

    And to prove out the concept of how an application would run on its new network, Dfinity today demonstrated an open social network called LinkedUp. The startup has rather cheekily called this “an open version of LinkedIn,” the Microsoft-owned social network for professionals. Unlike LinkedIn, LinkedUp, which runs on any browser, is not owned or controlled by a corporate entity. LinkedUp is built on Dfinity’s so-called Internet Computer, its name for the platform it is building to distribute the next generation of software and open internet services.

  • Introducing The Lunduke Journal - New Name, New Website

    With so many people reading the articles, obviously those articles need to live somewhere under my control.

    Up until now I've been publishing them over on Patreon. I made those articles free for everyone to read, but utilized Patreon as simply a publishing platform. This worked well enough for the occasional article... but that needed to change.

    You can now find every article published under the Lunduke Journal name right here at Lunduke.com. You can also find an always up to date RSS feed of the articles right here as well. That way you can get notified the moment a new article (and corresponding episode, audio and video) is published.

    If you've been enjoying the content over the last few months, never fear. No significant changes to any of that, outside of the name, branding, and website changes. The meat of what made The Lunduke Show is exactly the same in The Lunduke Journal.

  • Results of the Pan-European Quantum Internet Hackathon

    In November 2019, we organised the first ever multi-location Quantum Internet hackathon.

    Since the Quantum Internet is still really new, most practical results were obtained by sharing existing software and protocols and receiving feedback on how to improve them. Actual bug fixes, additional features and new software were also valuable outcomes of the event. All the links to the produced software were collected on the PEQI2019 pages on GitHub.

  • How fast can a new internet standard for sharing patient data catch fire?

    Six big tech companies -- Microsoft, Google, Amazon, IBM, Oracle and Salesforce -- have also joined to support FHIR and broader sharing of health care data through a government-endorsed project called Blue Button, which is intended to make it easier for patients to view and download their health records.

    Consumer advocates and cybersecurity experts warn that personal health information shared on the web could be compromised. They want to make sure the risk is minimized before any widespread rollout of FHIR products. Patients do not have a say in how their health providers store medical information, but patients can request their records be sent in the format they prefer, including paper.

    Facilitating access to all that data for both patients and providers without first determining how to keep it secure may open a Pandora's box that can never be shut, warned David Finn, executive vice president of strategic innovation for CynergisTek, a Mission Viejo, California, and Austin, Texas-based cybersecurity consulting firm.

  • California to resume Elsevier talks after signing deals elsewhere

    The 10-campus California system -- now more than six months without access to Elsevier's library of 2,500 journals -- announced that the two sides will hold "a meeting to explore reopening negotiations" early this year.

    Given the open access deals the California system has signed elsewhere, the system's library leaders said in a statement, "we are hopeful that this suggests that the publisher is ready to discuss deals that align with UC's goals".

    The California-Elsevier showdown has been watched nationally and globally, a reflection of the size and importance of the two players and the multibillion-dollar stakes surrounding the challenge across academia of making published research findings open to all.

Security Leftovers: BlueTooth, Spectre/Meltdown and Huawei Disputes

  • BlueTooth Security Risks

    Security risks involving bluetooth vulnerabilities include techniques known as: bluebugging, bluesnarfing, bluejacking, denial of service and exploits for different holes. When a device is configured in discoverable an attacker may try to apply these techniques. Today mobile security was strongly increased and most attacks fail, yet sometimes security holes are discovered and new exploits emerge. As mobile devices prevent the user from installing unmonitored software freely most of attacks are difficult to carry out. This tutorial describes the most common Bluetooth attacks, the tools used to carry out these attacks and the security measures users can take to prevent them. [...] While bluetooth attacks aren’t widely used (when compared with other types of attacks like phishing or DDOS) almost every person carrying a mobile device is a potential victim, therefore in our countries most people are exposed, also through bluetooth, to sensitive data leak. On the other hand most manufacturers already patched devices to protect them from almost all attacks described above, but they only can issue a fix after the vulnerability was discovered and published (like with any vulnerability). While there is not defensive software the best solution is to keep the device turned off in public spaces, since most attacks require a short range you can use the device safely in private places. I hope you found this tutorial on Bluetooth Security Risks useful. Keep following LinuxHint for more tips and updates on Linux and networking.

  • Arm Has Many Changes On Tap For Linux 5.6 From Spectre/Meltdown Bits To New RNG

  • The Pentagon pushes back on Huawei ban in bid for ‘balance’

    Huawei may have just found itself an ally in the most unexpected of places. According to a new report out of The Wall Street Journal, both the Defense and Treasury Departments are pushing back on a Commerce Department-led ban on sales from the embattled Chinese hardware giant. That move, in turn, has reportedly led Commerce Department officials to withdraw a proposal set to make it even more difficult for U.S.-based companies to work with Huawei. Defense Secretary Mark Esper struck a fittingly pragmatic tone while speaking with the paper, noting, “We have to be conscious of sustaining those [technology] companies’ supply chains and those innovators. That’s the balance we have to strike.”
