  • What is DevOps? Gareth Rushgrove Explains

    Gareth Rushgrove is known by many people as the creator and editor of the popular DevOps Weekly email newsletter, and he spent several years working for the U.K. Government Digital Service (GDS) on GOV.UK and other projects. As Senior Software Engineer at Puppet, you can find him building some of the latest infrastructure automation products when he isn't speaking at events on a wide variety of DevOps and related topics.

  • Coffee Shop DevOps: Clearly defining and communicating team goals

    Last month I interviewed the Cockpit team about team practices. We had an interesting conversation from many different angles, but most notable were the themes we kept returning to: understanding goals, the importance of feedback loops, and committing to open and transparent communication. I found I could easily correlate each of these back to other teams I have worked with in the past. When you inspect the behaviors and inner workings of a team, these themes seem to be remarkably central to team conflict.

  • Google's Magenta Seeks to Leverage TensorFlow for Art and Music

    As we've noted, artificial intelligence and machine learning are going through aamini-renaissance right now. Google recently made a possibly hugely influential contribution to the field of machine learning. It has open sourced a program called TensorFlow that is freely available. It’s based on the same internal toolset that Google has spent years developing to support its AI software and other predictive and analytics programs.

    In a related open project from the Google Brain team, dubbed Magenta, Google is calling for efforts to leverage TensorFlow and machine learning to create compelling art and music. Some of the early examples from this effort are eye-opening.

  • Nintendo NX Spec Rumors Say The Console's Games May Support Open-Source Virtual Reality

    Nintendo NX spec rumors keep coming, and the latest chatter suggests that the console may support open-source virtual reality for certain games. This would allow the 2017 machine to compete with the likes of Oculus Rift and PlayStation VR.

    The news comes to Design & Trend via Chinatimes as referenced by the sometimes-accurate Digitimes. The report should be taken with a grain of salt, but it's certainly interesting.

    As indicated by the secondary source, Nintendo allegedly has a production partnership with a certain chipmaker called Pixart. While the outfit is most known for its heart-rate monitoring hardware, mentions are also made to "tape-out chips supporting VR technology by the end of 2016." These chips "will support next-generation Nintendo NX game machines."

  • Has open source become the default business model for enterprise software?

    The announcement this week that Splice Machine is open-sourcing its product has become just the latest reminder that -- in emerging technology markets -- open source is increasingly the rule, not the exception.

    Open-source software is one of those overnight successes that's been a decade and more in the making. It's a far cry from the early aughts when Red Hat and JBoss blazed a trail that still has doubters. Arguably, there's still the issue of whether Red Hat, a publicly-traded, open source company, is a Unicorn from a different twist. Nonetheless, today, when we get acquainted to a new startup, one of the first questions that we pop is whether they're open source.

  • Spark-powered Splice Machine goes open source

    Splice Machine, the relational SQL database system that uses Hadoop and Spark to provide high-speed results, is now available in an open source edition.

    Version 2.0 of Splice Machine added Spark to speed up OLAP-style workloads while still processing conventional OLTP workloads with HBase. The open source version, distributed under the Apache 2.0 license, supplies both engines and most of Splice Machine's other features, including Apache Kafka streaming support. However, it omits a few enterprise-level options like encryption, Kerberos support, column-level access control, and backup/restore functionality.

  • Splice Machine's New Open-Source RDBMS Sandbox Goes Live on Amazon Web Services (AWS)
  • As Splice Machine's Database Goes Open Source, Apache Spark Could Spur it On

    Around the time that Splice Machine announced a milestone version of its RDBMS, which it bills as "the first hybrid in-memory RDBMS powered by Hadoop and Spark," its fortunes were starting to rise along with Hadoop's and Spark's. In the big data space, there is tremendous need to marry powerful data analytics tools with powerful database tools. If you're focusing on the Big Data and NoSQL arenas, along with relational databases, Splice Machine is worth a look.

    Now, Splice Machine is going open source, and it is also going live in a sandbox version on Amazon Web Services (AWS), so you can easily give it a try.

    Splice Machine aims to be a database solution that incorporates both the scalability of Hadoop, ANSI SQL, ACID transactions, and the in-memory performance of Spark.

  • OpenWest conference emphasizes importance of open-source technology

    Over 2,000 individuals wearing circuit board badges learned and talked about all things open source this past weekend at the South Towne Expo Center. The OpenWest conference is the largest regional tech conference promoting all things open— hardware, software, data, standards and more.

    The conference is put on by Utah Open Source and sponsored by V School, Electronic Frontier Foundation, Podium and Protocol, among others.

    Open source refers to software that anyone can see and edit. Open-source code is typically created in collaboration with both online and real-life communities. Liz Sands-Adams, OpenWest’s Director of the Privacy Education Track, said, “OpenWest survives because of a volunteer community that believes in empowering the open-source communities around them.”

  • Getting Exposure for Your Open Source Project

    With so many great open source projects spreading like wildfire, it is a great time to be a developer! I spend a considerable amount of time looking for great ideas across the open source community. For me, I'm always searching for modules we might include in our distributions, projects that could be enhanced and commercialized, or even crossovers into other areas for innovations. If something really resonates with our business we will apply resources to furthering that project.

    Generally, the first thing I do is hit the project description to see if it makes a connection with me. If it does, I’ll try it out or tag it for further research, perhaps even mention it on Twitter or discuss internally on a relevant Slack channel. Note, I did not look at your code, I looked at the idea. If you want your code to get out into the community, and actually ignite something bigger, you need to make sure your project is discoverable.

  • Simplify your OpenStack installation with open source tools

    To avoid any confusion, let's make this clear: OpenStack is a cloud-operating system. OpenStack is not a VM, but rather sits on top of VMs. Also, OpenStack is written in Python.

    As you install each component, OpenStack installs a command-line tool that works in tandem with it. The problem is that each component -- of which there are dozens -- has its own command-line tool, each with its own name and parameters. For example, you run Keystone to install users and roles in the Identity Service. Then you run Glance to load VM images. You would then use Nova to deploy those images. After a while, the sheer number of components and their respective command-line tools can get overwhelming.

    So, other than the command line, what options do we have to simplify the OpenStack installation process? Let's have a look.

  • Apache Graduates Another Big Data Project to Top Level
    For the past year, we've taken note of the many 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. Only days ago, 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 now, 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.
  • Spark 2.0 takes an all-in-one approach to big data

This comes as a number of other projects -- including others from the Apache Foundation -- provide their own ways to boost real-time and in-memory processing.
  • Why Uber Engineering Switched from Postgres to MySQL
    The early architecture of Uber consisted of a monolithic backend application written in Python that used Postgres for data persistence. Since that time, the architecture of Uber has changed significantly, to a model of microservices and new data platforms. Specifically, in many of the cases where we previously used Postgres, we now use Schemaless, a novel database sharding layer built on top of MySQL. In this article, we’ll explore some of the drawbacks we found with Postgres and explain the decision to build Schemaless and other backend services on top of MySQL.

  • Water resilience that flows: Open source technologies keep an eye on the water flow
    Communities around the world are familiar with the devastation brought on by floods and droughts. Scientists are concerned that, in light of global climate change, these events will only become more frequent and intense. Water variability, at its worst, can threaten the lives and well-beings of countless people. Sadly, humans cannot control the weather to protect themselves. But according to Silja Hund, a researcher at the University of British Columbia, communities can build resilience to water resource stress. Hund studies the occurrence and behavior of water. In particular, she studies rivers and streams. These have features (like water volume) that can change quickly. According to Hund, it is essential for communities to understand local water systems. Knowledge of water resources is helpful in developing effective water strategies. And one of the best ways to understand dynamic water bodies like rivers is to collect lots of data.

  • JavaScript keeps its spot atop programming language rankings
    U.K.-based technology analyst firm RedMonk just released the latest version of its biannual rankings of programming languages, and once again JavaScript tops the list, followed by Java and PHP. Those are same three languages that topped RedMonk’s list in January. In fact, the entire top 10 remains the same as it was it was six months ago. Perhaps the biggest surprise in Redmonk’s list—compiling the “performance of programming languages relative to one another on GitHub and Stack Overflow”—is that there are so few surprises, at least in the top 10.
  • Plenty of fish in the C, IEEE finds in language popularity contest
    It's no surprise that C and Java share the top two spots in the IEEE Spectrum's latest Interactive Top Programming Languages survey, but R at number five? That's a surprise. This month's raking from TIOBE put Java at number one and C at number two, while the IEEE reverses those two, and the IEEE doesn't rank assembly as a top-ten language like TIOBE does. It's worth noting however that the IEEE's sources are extremely diverse: the index comprises search results from Google, Twitter, GitHub, StackOverflow, Reddit, Hacker News, CareerBuilder, Dice, and the institute's own eXplore Digital Library. Even then, there are some oddities in the 48 programming environments assessed: several commenters to the index have already remarked that “Arduino” shouldn't be considered a language, because code for the teeny breadboard is written in C or C++.
