  • Hazelcast joins Eclipse Foundation to collaborate on open source enterprise Java

    Hazelcast, the open source In-Memory Data Grid (IMDG) with tens of thousands of installed clusters and over 39 million server starts per month, announced it had joined the Eclipse Foundation, bringing extensive Java-driven community experience to a host of open source projects.

    Working collaboratively with other members of the Eclipse community, Hazelcast’s primary focus will be on JCache, the Eclipse MicroProfile and EE4J.

    In particular, Hazelcast will be collaborating with members to popularise JCache, a Java Specification Request (JSR-107) which specifies API and semantics for temporary, in-memory caching of Java objects, including object creation, shared access, spooling, invalidation, and consistency across JVM’s. These operations help scale out applications and manage their high-speed access to frequently used data. In the Java Community Process (JCP), Hazelcast’s CEO, Greg Luck, has been the co spec lead and then maintenance lead on “JCache – Java Temporary Caching API” since 2007.

  • GitLab update: Moving to the next step

    I have good news, after few meetings and discussions with GitLab we reached an agreement on a way to bring the features we need and to fix our most important blockers in a reasonable time and in a way that are synced with us. Their team will fix our blockers in the next 1-2 months, most of them will be fix in the release of 22th of December and the rest if everything goes well in the release of 22th of January. The one left that out of those 2 months is a richer UI experience for duplicates, which is going to be an ongoing effort.

    Apologies for the blockage for those that regularly asked to migrate their project, I wanted to make sure we are doing things in the right steps. I also wanted to make sure that I get feedback and comments about the initiative all around in my effort to make a representation of the community for taking these decisions. Now it’s the point where I’m confident, the feedback and comments both inside and outside of our core community has been largely that we should start our path to fully migrate to GitLab.

  • Khronos Releases SYCL 1.2.1 With TensorFlow Acceleration, C++17 Alignment

    SYCL as a reminder is Khronos' higher-level OpenCL programming model based on C++. It's been a while since the last update, but a new point release is now available.

    SYCL 1.2.1 is based on OpenCL 1.2 and improves support for machine learning tasks, supports TensorFlow acceleration, and aligns with the latest C++17 standard. SYCL 1.2 had previously been based on C++11/C++14. The C++17 standard was just firmed up this month.

  • Python data classes

    The reminder that the feature freeze for Python 3.7 is coming up fairly soon (January 29) was met with a flurry of activity on the python-dev mailing list. Numerous Python enhancement proposals (PEPs) were updated or newly proposed; other features or changes have been discussed as well. One of the updated PEPs is proposing a new type of class, a "data class", to be added to the standard library. Data classes would serve much the same purpose as structures or records in other languages and would use the relatively new type annotations feature to support static type checking of the use of the classes.

    PEP 557 ("Data Classes") came out of a discussion on the python-ideas mailing list back in May, but its roots go back much further than that. The attrs module, which is aimed at reducing the boilerplate code needed for Python classes, is a major influence on the design of data classes, though it goes much further than the PEP. attrs is not part of the standard library, but is available from the Python Package Index (PyPI); it has been around for a few years and is quite popular with many Python developers. The idea behind both attrs and data classes is to automatically generate many of the "dunder" methods (e.g. __init__(), __repr__()) needed, especially for a class that is largely meant to hold various typed data items.

Linux Foundation: OpenContrail, SDNs, ONAP

  • Juniper Flips OpenContrail To The Linux Foundation
    It’s a familiar story arc for open source efforts started by vendors or vendor-led industry consortiums. The initiatives are launched and expanded, but eventually they find their way into independent open source organizations such as the Linux Foundation, where vendor control is lessened, communities are able to grow, and similar projects can cross-pollinate in hopes of driving greater standardization in the industry and adoption within enterprises.
  • Juniper Hands OpenContrail SDN to Linux Found. Before It's Too Late
    After failing to develop a community around the project and receiving pushback from a major backer, Juniper may be saving Contrail from becoming irrelevant
  • CableLabs Announces Two Open Source Projects for NFV
    SNAPS is an overarching program at CableLabs to facilitate the adoption of software-defined networking (SDN) and network functions virtualization (NFV) within the CableLabs’ community. The organization says it spearheaded SNAPS to fill in gaps within open source to ease the adoption of SDN and NFV for its cable members.
  • Bell becomes first operator to launch ONAP in production
    Canadian telecommunications company Bell announced it has become the first company to launch an open source version of the Open Network Automation Platform (ONAP) in production. The announcement was noted by Arpit Joshipura, general manager of networking and orchestration at the Linux Foundation, in a company blog post. According to Joshipura, the news marks a first step toward using ONAP as a common platform across Bell’s network as the company re-aligns itself to follow a multi-partner DevOps model.

  • When Waze Won't Help, Palestinians Make Their Own Maps
    If you want to drive the 15 or so miles from Jerusalem to the city of Jericho, in the Palestinian Territories, Google Maps will tell you: “Can’t find a way there.” Waze will issue a warning: “Caution: This destination is in a high risk area or is prohibited to Israelis by law.” If you press “Confirm Drive” nonetheless, the app will direct you, just not all the way. When you pass from Israel into the West Bank, part of the occupied Palestinian Territories, Waze’s directions simply end. To keep going, you need to change your setting to allow access to “high risk” areas. Even then, GPS coverage tends to be limited.
  • Using Gmail with OAUTH2 in Linux and on an ESP8266
    One of the tasks I dread is configuring a web server to send email correctly via Gmail. The simplest way of sending emails is SMTP, and there are a number of scripts out there that provide a simple method to send mail that way with a minimum of configuration. There’s even PHP mail(), although it’s less than reliable.
  • Simplicity Before Generality, Use Before Reuse
    A common problem in component frameworks, class libraries, foundation services, and other infrastructure code is that many are designed to be general purpose without reference to concrete applications. This leads to a dizzying array of options and possibilities that are often unused or misused — or just not useful. Generally, developers work on specific systems; specifically, the quest for unbounded generality rarely serves them well (if at all). The best route to generality is through understanding known, specific examples, focusing on their essence to find an essential common solution. Simplicity through experience rather than generality through guesswork.
  • What Ruby Needs
    Of all of the questions we receive at RedMonk, one of the most common concerns programming languages. Whether from members of a given community or a commercial entity, the desire is to better understand a given language’s trajectory and the context around it. Is it going up or down, and what are the reasons for that direction? And, of course: can that direction be meaningfully changed? Recently, we’ve received several such inquiries around Ruby. For those with an interest in the language, then, the following is a quick public summary of the answers we’ve been providing privately.
  • HTML 5.2 is done, HTML 5.3 is coming
    Today W3C releases HTML 5.2. This is the second revision of HTML5, following last year’s HTML 5.1 Recommendation. In 2014 we expressed a goal to produce a revision roughly every year; HTML 5.2 is a continuation of that commitment. This Recommendation like its predecessor provides an updated stable guide to what is HTML. In the past year there has been a significant cleanup of the specification. We have introduced some new features, and removed things that are no longer part of the modern Web Platform, or that never achieved broad interoperability. As always we have also fixed bugs in the specification, making sure it adapts to the changing reality of the Web. Many of the features added integrate other work done in W3C. The Payment Request API promises to make commerce on the Web far easier, reducing the risks of making a mistake or being caught by an unscrupulous operator. New security features such as Content Security Policy protect users more effectively, while new work incorporated from ARIA helps developers offer people with disabilities a good user experience of their applications.

  • Startup Aims to Build Open-Source Telecom Ecosystem on Blockchain
    There are 2,000+ mobile network operations in charge of providing communication services at global scale. However, the traditional infrastructure is centralized, inflexible and inaccurate. Common services like 3G/4G, Wi-Fi, BOSS mobile communications solutions and companies that use cloud-based communications solutions are often unable to render accurate content billing and distribution. Conventional mobile packages overcharge customers, not to mention that they pose concerns around data transmissions. An alternative solution to average mobile network providers could be Blockchain technology.
