  • Open Source Processors: Fact Or Fiction?

    Open source processors are rapidly gaining mindshare, fueled in part by early successes of RISC-V, but that interest frequently is accompanied by misinformation based on wishful thinking and a lack of understanding about what exactly open source entails.

    Nearly every recent conference has some mention of RISC-V in particular, and open source processors in general, whether that includes keynote speeches, technical sessions, and panels. What’s less obvious is that open ISAs are not a new phenomenon, and neither are free, open processor implementations.

  • Will Open-Source EDA Work?

    Open-source EDA is back on the semiconductor industry’s agenda, spurred by growing interest in open-source hardware. But whether the industry embraces the idea with enough enthusiasm to make it successful is not clear yet.

    One of the key sponsors of this effort is the U.S. Defense Advanced Research Projects Agency (DARPA), which is spearheading a number of programs to lower the cost of chip design, including one for advanced packaging and another for security. The idea behind all of them is to utilize knowledge extracted from millions of existing chip designs to make chip engineering more affordable and predictable.

  • Why Autonomous Vehicle Developers Are Embracing Open Source

    There's a growing trend of autonomous vehicle developers open-sourcing their software tools and hardware, even for applications outside of automotive.

  • Rugged open-source inertial measurement unit sensor offers affordable and rugged solution

    ACEINNA offers the new OpenIMU300RI. The device is a rugged, open-source, sealed-package, 9-DOF IMU for autonomous off-road, construction, agricultural and automotive vehicle applications. This new open-source IMU enables engineers to simply optimise an attitude, navigation or other algorithm for their vehicle/application and run it in on the IMU.

    [...]

    “Different vehicle platforms have different dynamics,” explains James Fennelly, product manager at ACEINNA. “To get the best performance, the attitude, navigation or other algorithm needs to be tailored for each vehicle platform and application. The ACEINNA OpenIMU300RI open-source platform gives designers a flexible and simple-to-integrate IMU solution that can be easily optimized for a wide range of vehicles and applications.”

  • Open Source ESP32 3D Printer Board Supports Marlin 2.0 Firmware
  • The Octopus is a 5K full frame open source camera that lets you swap out sensors

    Now that digital imaging sensors are starting to become more freely available to the masses, all kinds of open source projects have been popping up that use them. Most of them are typically fairly limited to things like the Raspberry Pi or development boards like the Arduino and ESP32.

    But now, there is a new and pretty serious looking open source camera out there. It’s called the Octopus, it has interchangeable sensors that go up to 5K full frame, it’s fully programmable and runs on the open source operating system, Linux.

  • ScopeFun open source all-in-one instrumentation

    ScopeFun has launched a new project via Crowd Supply for their open source all-in-one instrumentation hardware aptly named the ScopeFun. ScopeFun Has been created to provide an affordable platform that offers the following tools : Oscilloscope, Arbitrary waveform generator, Spectrum analyzer, Logic analyzer and Digital pattern generator .

    The hardware supports any accompanying software runs on Windows, Linux, and Mac and also provides a Server Mode that supports remote connections over an IP network. “A Xilinx Artix-7 FPGA and a Cypress EZ-USB FX3 controller allow the board to interface with a PC while maintaining fast data rates. Samples are buffered using 512 Megabytes of DDR3 SDRAM.

  • Bloom Chair is an open source furniture that lets you design your own piece

    Call it modular, call it DIY, call it I-have-control-over-my-interiors; the purpose of the Bloom Chair is to let you customize your chair, just the way you like it to be. It’s a collaborative effort between you and the manufacturer, where you get to download the modular design, cut it yourself and finally assemble it. While you make your piece, you have the liberty of modifying the pattern and making the end-shape define your vision. Haffun!

Sway 1.7 improves screen capture and virtual reality in Wayland

sway 1.7 is available to continue the evolution of this Wayland composer and window manager based on or inspired by the popular i3. Despite being “just” a window manager, Sway is one of the most interesting developments when it comes to Wayland composers, and not only that, but is considered by many to be the best implementation of the protocol out there, even by comparison. on top of the GNOME Mutter. On the other hand, it has been one of the brave few to openly say “no” to NVIDIA and EGLStreams in order to narrowly defend the standards agreed upon by almost everyone around Wayland and GBM. You know, the word “standard” gives NVIDIA hives, and the exact reasons are known only to the corporation’s executives. The first notable new feature of Sway 1.7 is the remove option --my-next-gpu-wont-be-nvidia, so the ones that users will have to use from now on --unsupported-gpu instead. It’s important to note that, at least officially, the official NVIDIA driver is still not supported (Nouveau should be fine), but we assume that this is a first step towards integrating the particular GBM implementation powered by the GPU manufacturer.

  • Hashing out the hash command on Linux | Network World

    When you type “hash” on a Linux system, you could get one of two very different responses depending on the shell you are using. If you are using bash or a related shell such as ksh, you should see a list of the commands that you have used since your terminal session began, sometimes with a count of how many times each command was used. This can be more useful than using the history command if you just want to see your very recent command activity, but the hash command is not a single executable. Instead, it relies on your shell.

  • Learn About Blender and Maybe Get a Free Book – What’s Not to Like?

    The event is Blender 101, an online event from the All Things Open folks, which will feature Jason van Gumster, author of Blender for Dummies, which is popular enough to now be in its fourth edition. Better yet, some copies of the book will be given away “to randomly chosen attendees.”

    When you run your own executable command or shell script on Linux, you must prepend ./ to the Unix command. But why? Why must you use a dot slash to run commands in Unix? You don’t have to do that in Windows with a batch file.

  • What Is Doas and How to Install It

    Doas is a privilege escalation program similar to sudo. It is designed to be as lightweight and simple as possible. It is the default privilege escalation program for OpenBSD but also available for other UNIX-like operating systems through the OpenDoas program.

  • Shell Aliases Every Linux User Needs - Invidious

    One of the most common questions I get from new-to-Linux users is, "How can I become a power user?" Well, learning the terminal and the terminal commands is the best thing you can do. And big part of becoming more proficient at the command line is creating your own Bash aliases. So today, I'm taking a fresh install of Ubuntu and adding aliases to it's bashrc. These are aliases that I think most, if not all, Ubuntu users would find helpful.
