  • RAKWireless Introduces RAK7200 LoRa Tracker | Features & Specifications
  • Padauk PMS150C “3 Cents” MCU Supports SDCC Open Source Toolchain
  • OpenHW Group Launched
  • Spain's First Open Source Satellite

    [Fossa Systems], a non-profit youth association based out of Madrid, is developing an open-source satellite set to launch in October 2019. The FossaSat-1 is sized at 5x5x5 cm, weighs 250g, and will provide free IoT connectivity by communicating LoRa RTTY signals through low-power RF-based LoRa modules. The satellite is powered by 28% efficient gallium arsenide TrisolX triple junction solar cells.

    The satellite’s development and launch cost under EUR 30000, which is pretty remarkable for a cubesat — or a picosatellite, as the project is being dubbed. It has been working in the UHF Amateur Satellite band (435-438 MHz) and recently received an IARU frequency spectrum allocation for LoRa of 125kHz.

  • Fitness Trackers Don't Have To Be Proprietary

    The OpenHAK is an open-source fitness tracker in a 3D printed wristwatch case that measures your heart rate and counts your steps, offering the resultant data for you to collect via Bluetooth. At its heart is a Sparkfun Simblee module, with heart rate sensing through a Maxim MAX30101 and step counting .by a Bocsh BMI160. It’s designed for expandability from the start with a header bringing out useful interface lines. In the prototype, they’ve used this to support a small OLED display. The result is a fitness tracker watch that may not match some of the well-known proprietary devices, but which remains completely open and probably costs a lot less too.

  • CutiePi is an open source Raspberry Pi-based tablet (coming in late 2019?)

    The CutiePi is hardly the first tablet built around one of Raspberry Pi’s tiny, low-cost computers. But it’s a pretty nifty looking addition to the category that combines an 8 inch touchscreen display with a Raspberry Pi Compute Module 3 Lite, a custom carrier board, and software to make the Linux-based Raspbian operating system touch-friendly.

    CutiePie’s developers have a working prototype and hope to begin selling the tablet later this year. But the whole project is open source, so anyone who wants to build their own can check out the code and hardware design files and give it a try.

  • CutiePi open source Raspberry Pi tablet unveiled

    Unfortunately, no information on pricing or worldwide availability has been released as yet for the CutiePi, but as soon as information comes to light, we will keep you updated as always.

  • Codefresh’s More Robust, Open Source Marketplace Makes Coding Easier, Faster, More Secure

    First deployed in December 2018, the Codefresh Marketplace makes it easier for code developers to find commands without having to learn a proprietary API – every step, browsable in the pipeline builder, is a simple Docker image. The Marketplace contains a more robust set of pipeline steps provided both by Codefresh and partners, such as Blue-Green and Canary deployment steps for Kubernetes, Aqua security scanning, and Helm package and deployment. All plugins are open source and users can contribute to the collection by creating a new plugin.

  • Codefresh freshens produce at the Kubernetes code marketplace

    Codefresh is the first Kubernetes-native CI/CD technology, with CI denoting Continuous Integration and CD denoting Continuous Delivery, obviously.

    The organisation has this month worked to improve its open source marketplace with features that focus on faster code deployment.

    First deployed in December 2018, the Codefresh Marketplace [kind of like an app store] allows developers to find commands without having to learn a proprietary API — this is because every step, which is browsable in the pipeline builder, is a simple Docker image.

  • DevOps World | Jenkins World: CircleCI orbs, DevOps Institute’s Ambassador Program, and Codefresh Marketplace

    DevOps and Jenkins is on full display this week at CloudBees’ DevOps World | Jenkins World taking place in San Francisco. In addition to the DevOps thought leaders and community members coming together to learn, explore and help shape the next generation of Jenkins and DevOps, a number of organizations took the opportunity to reveal new products.

    [...]

    SmartBear revealed TestEngine, a new solution designed to automate test execution in CI/CD environments. In addition, the company announced ReadyAPI 2.8 to accelerate functional, security and load testing of RESTful, SOAP, GraphQL and other web services. The new tools are aimed at accelerating API delivery.

    Users can now execute ReadyAPI, SoapUI Pro and SoapUI Open Source tests simultaneously on a central source that’s integrated into their development processes. This tackles the challenges that Agile and DevOps teams have such as complex deployments, large regression suites, and global development teams, according to SmartBear in a post.

  • What Is Developer Relations?

    Matthew Broberg, Advocate and Editor at opensource.com says that in practice the implementation of DevRel has been far from consistent. "DevRel, in theory, is the intersection of three disciplines: engineering, marketing, and community management," he says. "In practice, DevRel applies to a wildly popular set of job titles with wildly different expectations across different organizations."

    [...]

    Rebecca Fitzhugh, Principal Technologist at Rubrik agrees. "While there is certainly a marketing component when representing the company to the customer and community, it's equally about representing the customer to the company," she says. "Our DevRel team brings feedback from our customers to the product and engineering team in order to drive a better developer experience against our product's APIs."

Network transparency with Wayland: Final report.

Filed under
Graphics/Benchmarks

The goal of this 2019 Google Summer of Code project is to develop a tool with which to transparently proxy applications that use the Wayland protocol to be displayed by compositors. Unlike the original X protocol, only part of the data needed to display an application is transferred over the application's connection to the compositor; instead, large information transfers are made by sharing file descriptors over the (Unix socket) connection, and updating the resources associated with the file descriptors. Converting this side channel information to something that can be sent over a single data stream is the core of this work.

The proxy program I have developed for the project is called Waypipe. It can currently be found at gitlab.freedesktop.org/mstoeckl/waypipe. (I am currently looking for a better stable path at which to place the project; the preceding URL will be updated once this is done.) A few distributions have already packaged the program; see here; alternatively, to build and run the project, follow the instructions in the README and the man page. My work is clearly identified by the commit logs, and amounts to roughly ten thousand lines of C code, and a few hundred of Python.

Gadgets

Portable consoles are hardly new, and thanks to the Switch, they’re basically the most popular gaming devices in the world. But ClockworkPi’s GameShell is something totally unique, and entirely refreshing when it comes to gaming on the go. This clever DIY console kit provides everything you need to assemble your own pocket gaming machine at home, running Linux-based open-source software and using an open-source hardware design that welcomes future customization.

The GameShell is the result of a successful Kickstarter campaign, which began shipping to its backers last year and is now available to buy either direct from the company or from Amazon. The $159.99 ( on sale for $139.99 as of this writing) includes everything you need to build the console, like the ClockworkPi quad-core Cortex A7 motherboard with integrated Wi-Fi, Bluetooth and 1GB of DDR3 RAM — but it comes unassembled.

Linux 5.3 Kernel Yielding The Best Performance Yet For AMD EPYC "Rome" CPU Performance

Filed under
Graphics/Benchmarks
Linux

Among many different Linux/open-source benchmarks being worked on for the AMD EPYC "Rome" processors now that our initial launch benchmarks are out of the way are Linux distribution comparisons, checking out the BSD compatibility, and more. Some tests I wrapped up this weekend were seeing how recent Linux kernel releases perform on the AMD EPYC 7742 64-core / 128-thread processors.

For some weekend analysis, here are benchmarks of Linux 4.18 through Linux 5.3 in its current development form. All tests were done on the same AMD EPYC 7742 2P server running Ubuntu 19.04 and using the latest kernels in each series via the Ubuntu Mainline Kernel PPA.

Fedora 29 to 30 upgrade - How it went

Filed under
Red Hat

Alas, my Fedora 30 experience started strong with the first review and soured since. The test on the old laptop with Nvidia graphics highlighted numerous problems, including almost ending up in an unbootable state due to the wrong driver version being selected by the software center. With the in-vivo upgrade, I almost ended up in a similar state due to some incompatibility with extensions. I wasn't pleased by other glitches and errors, and the performance improvement margin isn't as stellar as the clean install test.

All in all, Fedora 30 feels like a rather buggy release, with tons of problems. I think versions 27 to 29 were quite robust overall, at least the Gnome version, but the latest edition is quite rough. That would mean I'd advise people upgrading to take care of their data, remember the possible snags like extensions, and triple check their hardware is up to the task, because apparently QA isn't cool anymore, and no one else will do this for you. All in all, Fedora 30 is very bleeding edge, finicky, definitely not for everyday use by ordinary desktop folks. It's a dev tool for devs, so if you want something stable and boring, search elsewhere.

GNU
Linux

One of the reasons Linux is great is because of how flexible it is. For example, it can run on everything from servers to your old laptop to a Raspberry Pi. For this reason, it’s also a fantastic platform for developers.

Whether you’re a seasoned developer or just using Linux to learn to program, you still have to choose a distribution. The reality is that you can pretty much be a developer with most Linux distros, but some have those little conveniences that make them head-and-shoulders above the crowd.

Here are the best Linux distros for developers.

Linux package managers are slow

Filed under
Linux

I measured how long the most popular Linux distribution’s package manager take to install small and large packages (the ack(1p) source code search Perl script and qemu, respectively).

Where required, my measurements include metadata updates such as transferring an up-to-date package list. For me, requiring a metadata update is the more common case, particularly on live systems or within Docker containers.

All measurements were taken on an Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz running Docker 1.13.1 on Linux 4.19, backed by a Samsung 970 Pro NVMe drive boasting many hundreds of MB/s write performance.
