Russia's Preference for Open-Source to Hurt U.S. Tech Stocks

Filed under

Amid rising political tensions with the U.S., Russia is planning to further lower its usage of licensed software from IT giants like International Business Machines Corp IBM , Microsoft Corporation MSFT , SAP AG SAP and Oracle Corporation ORCL .

Per Bloomberg, "The State Duma, Russia's lower house of parliament, is drafting a bill to restrict government agencies from buying licensed software, giving preference to open-source software."

The proposed law is an addition to an already existing federal law that came into effect on Jan 1, 2016, which restricts the use of foreign software in the public sector, if there is a domestic version available.

Mozilla’s Denelle Dixon-Thayer wrote about the details in her recent blog post.

  • Recognizing active user contributors to OpenStack

    Within the OpenStack community, there are countless people conducting tests, maintaining infrastructure, writing documentation, organizing community events, providing feedback, helping with project promotion, and countless other roles that may or may not show up under the traditional list of contributors. Since a fundamental tenant of OpenStack is that much of the project's governance comes from its active contributors, finding a way to expand the types of contributions that are "officially" recognized is an important step in bringing everyone's voice to the table.

  • Apache Milagro: A New Security System for the Future of the Web

    With 25 billion new devices set to hit the Internet by 2025, the need for a better worldwide cryptosystem for securing information is paramount. That’s why the Apache Milagro project is currently incubating at the Apache Software Foundation. It’s a collaboration between MIRACL and Nippon Telegram and Telegraph (NTT), and Brian Spector, MIRACL CEO and Co-Founder, discussed the project in his keynote at ApacheCon in May.

    Spector said the project was born in a bar on the back of a napkin after a brainstorm about how one would rebuild Internet security from the ground up. That sounds like a lot of work, but Spector believes it's absolutely necessary: the future of the Web is going to be very different from the past.

  • DE radiation protection agency overcomes lock-in

    Germany's Federal Office for Radiation Protection (Bundesamt für Strahlenschutz, BfS) is taking steps to rid itself of IT vendor lock-in. Within the next few years, it plans to have replaced its legacy proprietary analysis and reporting tools by modern, open source-based tools. Moreover, the new system, which is being tested, will improve the geographic information capabilities, and will lower costs significantly.

    The radiation protection agency was in set up in 1989, three years after the catastrophic nuclear accident in Chernobyl. Its main task is to protect population and environment from damages due to radiation.

    To help with decision-making and with generating of reports, the BfS’ crisis unit has for years been using a customised, proprietary software solution. This ‘Integrated Measuring and Information System’ (IMIS) lets BfS make sense of the data generated by some 1800 radiation measuring stations across the country. IMIS continuously monitors the environment and is able to detect small changes in radioactivity. Its results are merged, evaluated, refined and presented in well-arranged documents.

    What percentage of players in the telecom industry now consider the OpenStack cloud platform to be essential or important to their success? According to a survey commissioned by the OpenStack Foundation, a whopping 85.8 percent of them do. That is more hard evidence that we are seeing actual deployments take the place of evaluation when it comes to OpenStack in the enterprise.

    The survey was executed by Heavy Reading and received 113 responses from representatives of telecom companies around the world: 54 percent from the US, 14.2 percent from Europe, 11.5 percent from the Asia Pacific region, 8.9 percent each from Central/South America and Canada; and 2.7 percent from the Middle East. Here are more of the key findings.

Couchbase and the future of NoSQL databases

Filed under

Well, I've built and led developer communities for 10+ years at Sun, Oracle, and Red Hat, so I have experience in leading crossfunctional teams to develop and execute strategy, planning, and execution of content, and marketing campaigns and programs. I've also led engineering teams at Sun, and I’m a founding member of the Java EE team.

At Couchbase, a developer advocate helps developers become effective users of a technology, product, API, or platform. This can be done by sharing knowledge about the product using the medium where developers typically hangout. Some of the more common channels include blogs, articles, webinars, and presentations at conferences and meetups. Answering questions on forums and Stack Overflow, conversations on social media, and seeking contributors for open source projects are some other typical activities that a developer advocate performs on a regular basis.

27 Open Source DevOps Tools In 7 Easy Bites

Filed under

I recently wrote an article featuring 25 DevOps vendors worth watching. However, in the world of DevOps, there are an awful lot of good tools that don't really have a vendor attached, and I thought it was time to give the open source tools their due.

While I wrote that there are tools that don't have vendors, there are vendors that are attached to some of these open source tools. Those vendors provide development support, along with, in some cases, customer support and even proprietary versions of some of the tools that exist alongside their open source cousins. As long as there was an open source version that wasn't "crippleware," it was eligible for the cut.

  • French Company Sues Apple Because of Improper HTML5 Support in iOS

    Nexedi, a French software development company, is suing Apple in a French court because of the sorry state of HTML5 support on iOS, and because Apple actively prevents third-party browser engines from running on iOS.

    The company filed a civil lawsuit in France because a local law gives it the best chances of succeeding in its effort. A local French law passed a few years back prevents large companies from imposing unbalanced contracts on smaller businesses.

    Nexedi says that Apple forces software developers to sign an unfair contract when submitting an app to the iOS App Store that states that all web content should be handled by a WebKit-based browser engine.

    The French company's problem is that the WebKit engine is seriously lagging behind when it comes to supporting modern HTML5 features. Because Apple forces iOS app developers to use WebKit-based browsers, developers must invest serious time and effort into porting modern apps to work with the limited version of HTML5 supported in iOS, indirectly cutting down their profits.

  • The Point Of Docker Is More Than Containers
    Spending time with Docker during Cloud Field Day about a month ago opened my eyes to the larger ecosystem that Docker is building, and that others are building around it. There is so much more to Docker than just the idea of immutable containers. For a start, Docker made using containers easy. That’s no small feat for a tricky piece of technical infrastructure. Making it easy, and specifically easy for developers, to use removed a lot of friction that was no small contributor to the pain of other, earlier methods. It gave developers are really simple way to create a fully functional development environment, isolated from all other dependencies, with which to work.
  • What are the Top NFV Risks for Carriers?
    What are the risks of network functions virtualization (NFV)? As with any emerging technology, moving fast or picking the wrong components can do more harm than good. Let’s spend some time breaking down the NFV risks in building a virtual network. I have spent the few months gathering feedback from various service providers to get their view on whether NFV and its cousin software-defined networking (SDN) are ready for prime time. Even though many service providers expressed optimism that NFV technology is moving toward maturity, there are definitely cautionary tales on what to look out for. This article serves as an introduction to the challenges of NFV component selection – later articles will refer in more detail to the challenges in selecting NFV hardware and software components such as OpenStack and Open vSwitch.

And platforms are needed to help people avoid spending too much time on configuring the underlying infrastructure, perhaps by handing the work off to a service provider. Just in time for the Serverless conference in London, this post highlights some of the most widely used frameworks and platforms, as well as other supporting tools, that make successful serverless-based workloads happen.

But what about Linux? As it turns out, Linux has never been high on the list of priorities for the Spotify team, and at some point, the support was discontinued, then it was revived recently, which prompted me to give it a try. Seeking originality and uniqueness in my work, I opted for Fedora, only to learn that only builds for Debian-based distributions are available. In other words, Ubuntu and friends.
