  • Canonical Girds Its Cloud-Native Loins as Containers Gain Traction

    Nathan Rader will need to be blessed with the patience of a saint. As the director of NFV Strategy at Canonical, the company behind the Ubuntu open source Linux distribution, he's eager for communications service providers to not just talk about "cloud native" architectures based on containers (packages of self-contained software code and related dependencies), but actually deploy them.

    That's because a shift to cloud-native, container-based microservices by mobile, fixed and cable network operators could well result in greater traction in the communications network operator world for Canonical Ltd. , which has developed a version of the Kubernetes container orchestration system needed to manage multiple containers across multiple cloud platforms.

    Canonical regards itself as particularly well placed to benefit from any shift towards container-based deployments, as its Ubuntu operating system is already widely deployed in existing cloud initiatives and the company believes that Ubuntu is the "optimal choice" to underpin containers.

  • Alternatives when migrating from macOS Server

    DHCP, DNS, FTP, and Websites services are the most important services for enterprises to connect to and utilize the Internet for getting work done. And while their loss is lamented, admins with Mac CLI experience will feel right at home spinning up these services on any Linux distribution. For those still learning their way around Linux or simply prefer a GUI-based package manager, Ubuntu, and CentOS are two excellent Linux distros that offer a nice blend of performance and usability that will have you configuring DHCP scopes and DNS nameservers in no time.

  • Hardware Review - The ZaReason Virtus 9200 Desktop
  • Chrome OS 76 will disable Crostini Linux backups by default
    Essentially, this is still a work in progress feature. And I shouldn’t be terribly surprised by that, even though in my experience, the functionality hasn’t failed me yet. That’s because we know that the Chromium team is considering on a way to backup and restore Linux containers directly from the Files app on a Chromebook. That proposal is targeted for Chrome OS 78, so this gives the team more time to work that out, as well as any other nits that might not be quite right with the current implementation.
  • Andrei Lisita: Something to show for
    Unfortunately along with the progress that was made we also encountered a bug with the NintendoDS core that causes Games to crash if we attempt to load a savestate. We are not yet 100% sure if the bug is caused by my changes or by the NintendoDS core itself. I hope we are able to fix it by the end of the summer although I am not even sure where to start since savestates are working perfectly fine with other cores. Another confusing matter about this is that the Restart/Resume Dialog works fine with the NintendoDS core and it also uses savestates. This led me to believe that perhaps cores can be used to load savestates only once, but this can’t be the problem since we re-instantiate the core every time we load a savestate. In the worst case we might just have to make a special case for the NintendoDS core and not use savestates with it, except for the Resume/Restart dialog. This would sadden me deeply since there are plenty of NintendoDS games which could benefit from this feature.

  • A comparison of open source, real-time data streaming platforms
    A variety of open source, real-time data streaming platforms are available today for enterprises looking to drive business insights from data as quickly as possible. The options include Spark Streaming, Kafka Streams, Flink, Hazelcast Jet, Streamlio, Storm, Samza and Flume -- some of which can be used in tandem with each other. Enterprises are adopting these real-time data streaming platforms for tasks such as making sense of a business marketing campaign, improving financial trading or recommending marketing messages to consumers at critical junctures in the customer journey. These are all time-critical areas that can be used for improving business decisions or baked into applications driven by data from a variety of sources.
  • Amphenol’s Jason Ellison on Signal Integrity Careers and His Free, Open Source PCB Design Software
    Ellison, Senior Staff Signal Integrity Engineer at Amphenol ICC, gives his insight on the importance of networking, giving to the EE community, and his open-source signal integrity project. How does signal integrity engineering compare to other EE fields? What are open-source resources worth these days? What makes for a good work life for an engineer? Learn this and more in this Engineer Spotlight! Jason Ellison started down the path to becoming an electrical engineer because someone told him it was "fun and easy if you're good at math." In this interview with AAC's Mark Hughes, Ellison—a Senior Staff Signal Integrity Engineer at Amphenol ICC—describes how his career has grown from these beginnings into the rewarding and diverse work of signal integrity engineering.
  • Cruise open-sources Webviz, a tool for robotics data analysis [Ed: Releasing a little tool that's part of proprietary software so that it 'feels' more "open"]
    Cruise, the self-driving startup that General Motors acquired for nearly $1 billion in 2016, generates an enormous amount of data by any measure. It orchestrates 200,000 hours of driving simulation jobs daily in Google Cloud Platform, spread across 30,000 virtual cars in an environment running on 300,000 processor cores and 5,000 graphics cards. Both those cars and Cruise’s fleet of over 180 real-world autonomous Chevrolet Bolts make thousands of decisions every second, and they base these decisions on observations captured in binary format from cameras, microphones, radar sensors, and lidar sensors.

  • MIT Researchers Open-Source AutoML Visualization Tool ATMSeer
    A research team from MIT, Hong Kong University, and Zhejiang University has open-sourced ATMSeer, a tool for visualizing and controlling automated machine-learning processes. Solving a problem with machine learning (ML) requires more than just a dataset and training. For any given ML tasks, there are a variety of algorithms that could be used, and for each algorithm there can be many hyperparameters that can be tweaked. Because different values of hyperparameters will produce models with different accuracies, ML practitioners usually try out several sets of hyperparameter values on a given dataset to try to find hyperparameters that produce the best model. This can be time-consuming, as a separate training job and model evaluation process must be conducted for each set. Of course, they can be run in parallel, but the jobs must be setup and triggered, and the results recorded. Furthermore, choosing the particular values for hyperparameters can involve a bit of guesswork, especially for ones that can take on any numeric value: if 2.5 and 2.6 produce good results, maybe 2.55 would be even better? What about 2.56 or 2.54?

Raspberry Pi 4 is here!

The latest version of the Raspberry Pi—Raspberry Pi 4—was released today, earlier than anticipated, featuring a new 1.5GHz Arm chip and VideoCore GPU with some brand new additions: dual-HDMI 4K display output; USB3 ports; Gigabit Ethernet; and multiple RAM options up to 4GB. The Raspberry Pi 4 is a very powerful single-board computer and starts at the usual price of $35. That gets you the standard 1GB RAM, or you can pay $45 for the 2GB model or $55 for the 4GB model—premium-priced models are a first for Raspberry Pi. Read more
