  • Collabora developers mentor successful GSoC Projects

    Autumn is just around the corner. For many participants in the GSoC 2020, a busy and instructive summer full of hacking on open source projects came to an end a few weeks ago. Commits have been contributed and final reports have been written. This year experienced Collabora Productivity developers were again mentors for various projects of the Google Summer of Code for the LibreOffice project. Here are some examples of projects our team helped to succeed!

  • OpenBehavior: A Rich Directory for Open-source Behavioral Neuroscience Projects

    OpenBehavior is an open-source repository for tools, software, projects and scripts that are dedicated for behavioral neuroscience research.

    The main goal is to promote and accelerate the collaboration of open-source neuroscience projects, neuroscience researchers and developers.

    Currently, OpenBehavior has 145 projects and active community of developers and research who are supporting this project. The project is founded and maintained by a group of researchers and professors. It started 2016 by Mark Lubach (PhD) and Alexxai Karvitz (PhD).

    The project is funded by NASA DC Space Grant Consortium to ML, Summer 2017. However, It's still looking for more support as it's 100% volunteer work.

  • Taskcluster's DB (Part 1) - Azure to Postgres [Ed: Mozilla flirtations with Microsoft again]

    This is a deep-dive into some of the implementation details of Taskcluster. Taskcluster is a platform for building continuous integration, continuous deployment, and software-release processes. It’s an open source project that began life at Mozilla, supporting the Firefox build, test, and release systems.

    The Taskcluster “services” are a collection of microservices that handle distinct tasks: the queue coordinates tasks; the worker-manager creates and manages workers to execute tasks; the auth service authenticates API requests; and so on.

  • Open Source Drive-Thru Contributors [Ed: Openwashing agenda by VM Brasseur or how to 'farm' a community for 'free labour']

    VM Brasseur explains open source “drive-thru contributions” and explores how the process can be improved.

    In the ongoing efforts to create a sustainable free and open source software ecosystem—one where projects receive the attention they need without burning out their maintainers in the process—a lot of attention has justifiably fallen on increasing the number of FOSS contributors.

    Much of the discussion around increasing contributors assumes that the primary goal is to get contributors who will stick around and become community members and maintainers. It's certainly true that many hands make light work, and the more maintainers a project has the less likely it is that any one of them will bear the brunt of the work and burn out. But, this isn't the only way to support project sustainability through contributions. Another approach is to optimize your project for drive-thru contributors.

New Releases: EasyOS 2.5.1 and NuTyX 12-rc3

  • Easy Buster version 2.5.1

    EasyOS versions 1.x are the "Pyro" series, the latest is 1.3. Easy Pyro is built with packages compiled from source using 'oe-qky-src', a fork of OpenEmbedded. Consequently, the builds are small and streamlined and integrated. The Pyro series may have future releases, but it is considered to be in maintenance status. The "Buster" series start from version 2.0, and are intended to be where most of the action is, ongoing. Version 2.0 was really a beta-quality build, to allow the testers to report back. The first official release was 2.1. The main feature of Easy Buster is that it is built from Debian 10 Buster DEBs, using WoofQ (a fork of Woof2: Woof-CE is another fork, used to build Puppy Linux).

  • EasyOS 2.5.1
  • EasyPup 2.5 boots, 2.5.1 kernel panic

    Rodney has been reporting this for sometime, that he gets a kernel panic trying to boot recent releases of EasyOS or EasyPup. They are using a 5.4.x kernel, except for EasyPup 2.5, I used a 4.19.157 kernel, and that booted. He tried to upgrade to 2.5.1, got kernel panic. So, he is back on 2.5.

  • NuTyX 12-rc3 available

    I'm very please to announce the new NuTyX 12-rc3 testing release. The 64-bit version is a complete new project. They are no plan to release a version 12 of NuTyX in 32 bits.

  • ST adds FreeRTOS thread-aware debug for microcontrollers

    STMicroelectronics has added support for FreeRTOS thread-aware debug to its STM32CubeIDE development environment, completing its acquisition of the Atollic tools. ST has completed transferring major advanced features of Atollic TrueStudio for STM32 into STM32CubeIDE after acquiring Atollic in 2017. STM32CubeIDE with support for thread-aware debug of the open source FreeRTOS real time operating system further extends the tool’s features. FreeRTOS is now supported by Amazon as AmazonFreeRTOS for the AWS cloud service. The direct access to STM32CubeMX configuration functions simplifies project setup, selecting a target microcontroller from the complete STM32 portfolio, configuring GPIOs, clock tree, peripherals, and pin assignments. The tool allows developers to quickly analyse power consumption depending on the applications usage, as well as select middleware stacks and generate initialization code for the desired configuration.

Open Hardware: Arduino and 64-bit RISC-V

  • Arduino Blog » RobotSculptor uses a six-axis robot arm to sculpt clay models

    Robotic fabrication techniques such as 3D printing enable you to make a copy of a wide variety of items. Actually sculpting something out of clay, however, remains a largely human pursuit. One might also miss the individual style of a sculptor in a finished product. RobotSculptor, developed by a team of engineers from ETH Zurich and Disney Research, attempts to address both challenges. The system generates toolpaths from a base mesh design and allows artistic input via mouse strokes during the process. A six-axis robot arm then incrementally removes clay from the model-in-progress, using a custom loop tool.

  • 64-bit RISC-V core claims 10x better CoreMarks/Watt compared to other 3-5GHz CPUs

    Micro Magic unveiled an up to 64-bit RISC-V core showing a groundbreaking 110,000 CoreMarks/Watt, with a 3GHz chip consuming less than 70mW. The company claims 10 times better CoreMarks/Watt compared to other processors in the 3-5GHz range. Considering the spectacular promise and sudden demise of AI tech firm Magic AI, we should perhaps be wary of hyped up companies with Magic in their name. Yet, the astonishing claims about an incredibly efficient RISC-V core coming out of Sunnyvale, Calif. based EDA firm Micro Magic in recent weeks appear to be for real.

  • Arduino Blog » A (very) short guide to help you transition to the Arduino Science Journal

    Arduino acquired the Science Journal app from Google on August 5th, and the final handover takes place on December 11th, 2020. From that date, the Science Journal will no longer be supported by Google. If you haven’t exported your experiments and imported them into the Arduino Science Journal, we strongly encourage you to do so now, as your data will no longer sync with Google Science Journal after that date. [...] While we can’t disclose too much about our future plans for the app, we can tell you that we’ll ensure it will offer easy access to a stream of data that leverages your smartphone sensors, as well as Arduino sensors. The aim is to help learners understand the importance of an inquiry-based educational method rather than passive consumption of information. We’ll also continuously improve the accessibility of the app for all users, and find new ways of experimenting with science. In the near future, we’ll be interacting more with users, so you’ll hear more from us soon! We’ll also be adding more tutorials on our platform dedicated to Science Journal!

  • This Week in Rust 367
  • Philip Chimento: Advent of Rust

    I have a bit of time off and I decided to participate in Advent of Code 2020 after my coworker Adrián shared a link to it. I’ve heard that people use challenges like these as an excuse to learn a new programming language, and I have wanted to learn Rust for quite a long time now. Why Rust? From what I’ve heard, it’s a programming language oriented towards high performance and systems programming, like C or C++; but unlike those languages, it was designed in such a way to make it difficult or impossible to make mistakes such as buffer overflows or memory leaks. I have heard that it’s a lot more enjoyable to use than C++ as well. I did write a “Hello World” program in Rust some time ago, and I have heard things about Rust from others, so I wouldn’t be coming to it completely fresh. Nonetheless, fresh enough that I decided that the experience of writing something from scratch, in a new programming language, was unusual enough for me that I would keep a log while I was doing it. So here is that log. It’s a bit stream-of-consciousness. I’ve edited it so that it consists of complete sentences instead of just notes, but I’ve left in the mistakes and dead ends. I made this mainly so that I can look back later when I’ve learned more, and see what mistakes I made.
