  • 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.

  • 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!

Ubuntu vs Manjaro: Comparing the Different Linux Experiences

Ubuntu is the most popular Debian-based Linux distribution for desktops and servers. And Manjaro Linux is an Arch-based distro tailored for desktops. Both are entirely different when it comes to user experience and features. However, one of the common grounds is the desktop environment when considering Manjaro’s GNOME edition with Ubuntu. But, what exactly are the differences? Is the package manager on Manjaro better? Are software tools available on both Ubuntu and Manjaro? Here, we shall look at the differences in both the Linux distributions at certain key points. Read more

  • Experts urge VMware users to patch critical flaws right away

    Security professionals have warned that an authentication bypass flaw in VMware products needs to be patched as soon as possible to prevent its being exploited. VMware issued an advisory on Wednesday warning of the flaw affecting VMware Workspace ONE Access (Access), VMware Identity Manager (vIDM), VMware vRealize Automation (vRA), VMware Cloud Foundation and vRealize Suite Lifecycle Manager. Satnam Narang, staff research engineer at security outfit Tenable, said the vulnerabilities patched as part of VMware’s VMSA-2022-0014 advisory along with the Emergency Directive and associated alert published by the US’ Cybersecurity and Infrastructure Security Agency were an important reminder about the importance of patching vulnerabilities as early as possible.

  • EasyOS/Debian: Easy Bookworm version 0.3 released

    These are pre-alpha releases so far. When all the obvious bugs are found and it seems functionally equivalent to Easy Dunfell, then I will probably bump the version to match, say 3.5.

  • Time-out to explore ideas

    EasyOS is an experimental distribution, subject to change as I explore new ideas. I want to go into an exploratory binge now, toying with some fundamental structural changes, so might be a bit unresponsive to any questions posted on the forum.

  • Put A New Spin On Your 3D Printed Parts

    Once you get tired of printing keychains and earbud holders with your 3D printer, you’ll want to design things a bit more sophisticated. How about things that rotate? [3DSage] has a good how-to about how to integrate a simple motor and controller into a few different size boxes. Combined with some 3D printed linkages, these boxes can turn your project — printed or otherwise — into something that spins.

  • Things Are Getting Rusty In Kernel Land | Hackaday

    The other answer is that Rust is an easy fit with C code and kernel programming. Rust does it’s magic in the compiler. The code you write is what actually runs, without an interpreter or garbage collection trying to be helpful. Rust hasn’t overdosed on Object Oriented patterns, but meshes nicely with the C-style structs already used in the kernel. Even the stack model is very similar to C. There’s one problem with Rust’s memory-safe guarantee — it’s impossible to write a kernel that is formally memory-safe. A kernel has to write to unallocated memory, do weird pointer math, and other seemingly bizarre things to actually make our computers work. This doesn’t work well with a language that tries to guarantee that memory manipulations are safe. How do you write kernel code with Rust, then? Rust has added the unsafe keyword, allowing use of direct memory access and other such techniques that don’t work with Rusts’s memory guarantees. Keep the potential problems together, and it makes auditing easier. There’s at least one other language that may come to mind as an incremental update to C that tries to do some of these things: C++. Surely this would have been even a better fit, right? Kernel devs have some strong feelings about that idea. To put it gently, none of the improvements in C++ are useful in the context of the kernel, and some of the other changes just get in the way.

  • How to Get User Input in Java

    In programming languages, taking the user’s input is an essential task. In Java, multiple predefined classes are used to get the user’s input such as Scanner, BufferedReader, and Console class. All these classes utilizes various methods for handling input such as nextLine(), readLine(), etc.

  • How to convert string to int in Java

    Converting one data type to other data types is a common task in the prommer’s life. If we talk about the string to int conversion it can be achieved using two build-in methods i.e., Integer.ParseInt() and Integer.ValueOf(). Usually, we perform the string to int conversion when we have to execute mathematical operations over the strings containing numeric data.

  • Array of Pairs in C++

    The term pair refers to the combination of two values of different types. Pair allows you to keep two separate objects as a single unit. It is mostly utilized when storing tuples. The pair container is a basic container declared in the utility header that consists of two collected data or objects. The first element in the pair container is referred to as ‘first,’ while the second element is referred to as ‘second’, with the order fixed as (first, second). By default, the object of a specified array is allocated in a map or hash map of the type ‘pair,’ with all of the ‘first’ elements having unique keys paired with their ‘second’ value objects. To obtain the elements, we use the variable’s name followed by the dot operator and by the first or second keywords.

  • Dart Hello World

    Dart is a Google-developed static programming language. It allows for client-side and server-side application development. As per the GitHub adoption index, it has become the most widely used programming language because it incorporates the flutter toolkit. However, the Flutter Framework is commonly utilized in developing Android applications, iOS applications, IoT (Internet of Things), and online applications. Dart has a high syntactic and semantic similarity to JavaScript, Java, CPP, and python. It is a vibrant object-oriented language with lexical scope and closure. Dart was released in 2011, but it gained prominence after 2015 with the release of Dart 2.0. In this article, we will look at the basic representation of Dart syntax and how to print hello world in the dart programming language. The fundamental framework of Dart programming will be demonstrated here.
