Open Hardware and Some Traps

  • AgVa Phone Ventilator Connects to a Smartphone to Fight COVID-19

    One major highlight during this COVID-19 crisis is the lack of enough ventilators for patients, a piece of critical equipment that greatly affects the breathing of critically ill patients. There are not enough ventilators available in hospitals right now for all of the potential patients who will be struck by the virus, so it is clear we need more ventilators. Makers are joining the call to service with their existing maker tools, and an example is the attempt to make a low-cost, open-source Arduino ventilator device.

  • Raspberry Pi Dev Server Manages Triple-Boot System With Help From Ubuntu

    This Raspberry Pi project covers all of your on-the-go developer needs. Designed by a developer known as CodeF.red, it uses a Raspberry Pi 4 running Ubuntu to help manage his triple boot laptop rig. With the portable dev server, he can easily swap between the Windows, macOS and Linux. The server is running Ubuntu off an NVME drive connected via USB (we have also detailed how to install Ubuntu on Raspberry Pi). The unit is controllable with a Bluetooth keyboard and also features a touchscreen. The maker also upgraded the Pi's cooling capabilities with a 5V Noctua fan with a super-low noise profile. The dev server uses Docker and can be controlled via SSH. Since it uses Ubuntu, you can add plenty of additional tools, like Glances for cross-platform monitoring features. Like many other Pi projects, the creator crafted this one using hardware already had on hand. CodeF.red said via Reddit that he considers the NVMe drive "overkill," especially since the performance is limited by the USB connection. But after removing the drive from an old Mac, it was gathering dust and needed to be put to use.

  • Digital making at home: a guide for parents
  • NXP WiFi 6 Solutions Launched for Home, Enterprise, IoT and Automotive Markets
  • 3.5″ SubCompact SBC Leverages Intel Whiskey Lake Processor for Embedded & AI Applications

    The company provides Windows drivers for graphics, audio, I2C, touch controller, Ethernet, etc… Linux will certainly boot in the board, and I’d expect most features to work, but it’s still possible that some specific hardware features, like the touch controller, may not work properly or at all.

Google Chromebook vs. Gallium Chromebook

Chromebooks have been improving a lot over the years. They’re not just web browsers with keyboards anymore. Many Chromebooks can now run Linux programs via an included Crostini virtual machine container, and many can also run Android apps. (As long as it’s not enrolled in enterprise management: Be careful about buying refurbished Chromebooks.) Those additions can greatly improve the usefulness of Chromebooks and greatly reduces their limitations. A few months ago, I wrote that a $99 Chromebook with Gallium OS installed is so much better. That was just an editorial with a “how to” though and I didn’t provide any in-depth experimentation or proof, so that’s what we’re going to do in this article. I bought two refurbished $60 Lenovo N22 Chromebooks and installed Gallium OS on one of them while letting the other one update itself to the latest version of Chrome OS 80. This is after I got them un-enrolled from Google’s Enterprise Management of course. Read more

Canonical/Ubuntu: Snap Store, Center for Internet Security (CIS) and MAAS

  • An adventure through the Snap Store

    An application store with a large number of entries is a double-edged sword. It’s often a good sign of a vibrant, thriving community of software creators, developers and users working together. But then, people new to the ecosystem may struggle finding relevant content right away. The Snap Store currently offers about 7,000 applications, so exploration and discovery can take quite a bit of time and effort. We’d like to help you find useful, interesting applications by taking you on a little tour through the Snap Store.

  • CIS hardened Ubuntu: cyber attack and malware prevention for mission-critical systems

    The Center for Internet Security (CIS) is a nonprofit organisation that uses a community-driven process to release benchmarks to safeguard enterprises against cyber attacks. It is one of the most recognised industry standards that provides comprehensive configuration checklists to identify and remediate security vulnerabilities in a computing environment. CIS benchmark has hundreds of configuration recommendations, so hardening a system manually can be very tedious. For large deployments and clouds that may not be practically viable. To drastically improve this process for enterprises, Canonical has made CIS automation tooling available to its Ubuntu Advantage for Infrastructure customers. The compliance tooling has two objectives: it lets our customers harden their Ubuntu systems effortlessly and then quickly audit those systems against the published CIS Ubuntu benchmarks. The SCAP content for audit tooling that scans the system for compliance is CIS certified.

  • Questioning the doc

    Here’s a VLOG about some changes we’re making to the MAAS documentation. It’s all about using questions at the top of articles to help direct attention. This idea grew out of our frustration over long pages with lots of complex information. We tried a top table of contents, but that looks weird and requires a lot of policing to keep up-to-date.

Linux and Linux Foundation: Intel Media Linux Driver, LF Edge and Fintech Open Source Foundation

  • Intel Media Linux Driver Q1-2020 Released With Tiger Lake Features, Better VP9 Encode

    Intel's open-source multimedia crew has released their Media Driver Q1'2020 build for Linux users. This Intel Media driver is what provides Video Acceleration API (VA-API) capabilities for Intel GPU-based video encode/decode for Broadwell through next-gen Tiger Lake. The Intel Media Driver Q1-2020 release has continued its bring-up of Tiger Lake. New features for Tiger Lake that are now exposed on the video front are HEVC SCC (Screen Content Coding) decode, better robustness, enhanced tile mode support, and other changes.

  • Linux Foundation, LF Networking, and LF Edge Announce Rescheduled Dates and Full Agenda for Open Networking & Edge Summit North America 2020

    The Linux Foundation, the nonprofit organization enabling mass innovation through open source, along with co-hosts LF Networking, the umbrella organization fostering collaboration and innovation across the entire open networking stack, and LF Edge, the umbrella organization building an open source framework for the edge, announced today the rescheduled event dates for Open Networking & Edge Summit North America (ONES, formerly Open Networking Summit) and the complete session line-up. ONES North America 2020 will take place September 28-30 at the JW Marriott LA Live in Los Angeles, California. The summit line-up features prominent speakers from AT&T, eBay, Ericsson, Huawei Technologies, Rancher Labs, Red Hat, Toyota Motor Corporation, Verizon, VMware, Wells Fargo, Yelp, and more. The full event agenda is available here.

  • 'State of the Edge,' the Project to Define Edge Computing, Now Part of Linux Foundation

    LF Edge, the edge-focused project that the Linux Foundation started early last year, is growing. On Wednesday, State of the Edge, an open project to define, explain, and quantify an edge computing ecosystem, officially became part of LF Edge. The Open Glossary of Edge Computing, which had been a stand-alone project within LF Edge, is getting rolled into State of the Edge.

  • Fintech Open Source Foundation Joins Linux Foundation to Expand and Accelerate Development Across Financial Services

    The Linux Foundation, the nonprofit organization enabling mass innovation through open collaboration, and the Fintech Open Source Foundation (FINOS), a nonprofit whose mission is to accelerate adoption of open source software, standards and best practices in financial services, today announced that FINOS will become a Linux Foundation organization. To enable this effort, the Linux Foundation has agreed to acquire the FINOS operating assets. The Linux Foundation will position FINOS as its umbrella project through which to advance further development of open source and standards within the financial services industry. The FINOS team, led by Executive Director Gabriele Columbro, will join the Linux Foundation. Columbro will continue in his role.
