  • Lilbits: CutiePi Linux tablet, NXP i.MX 93 chips, Twitter Blue, and YouTube's Dislike button - Liliputing

    The CutiePi tablet with a built-in handle, a Raspberry Pi for brains, and Linux-based software is nearing release. Twitter is charging people willing to pay for an Undo Tweet button (and a few other perks). Google hopes YouTube might be a friendlier place if it hides the number of times the dislike button has been clicked on videos. And NXP has unveiled a new processor family.

  • Time to put this DIY absolute position encoder to work as a clock | Arduino Blog

    Being able to derive the absolute position of an object is vital in countless applications, primarily for anything that uses a motor. Instructables user holybaf had the idea to build their own rotary encoder, which has 60 degrees of resolution and utilizes a CD to act as a precise clock.

    To accomplish this, they first laid down a single circular track featuring patterns of light and dark areas that each correspond to a single value. By reading these areas with a set of six infrared emitters/detectors and comparing their current reading to the previous one, an absolute position can be determined.

  • Raspberry Pi Unveils 'Code Club World': A Way for Kids to Learn Code at Home - FOSS Force

    On Tuesday, the Raspberry Pi Foundation announced Code Club World, a child-friendly website purposed with helping children aged 9 to 13 “learn to make stuff with code.”

    In a blog announcing the project, Laura Kirsop, the Raspberry Pi Foundation’s head of learning experience, said the project was one result of the foundation’s efforts to create tools to help parents with homeschooling efforts during the Covid-19 pandemic.

    “When we spoke to parents and children about learning at home during the pandemic, it became clear to us that they were looking for educational tools that the children can enjoy and master independently, and that are as fun and social as the computer games and other apps the children love,” she said.

  • MXM modules showcase Nvidia Ampere

    Adlink’s “EGM-MXM-A” modules for edge AI bring Nvidia’s high-end Ampere graphics to MXM 3.1. The modules include RTX A1000, A2000, and A4500 graphics, with the latter offering 5,120 CUDA, 40 RT, and 160 Tensor cores for up to 17.8 TFLOPS.

    In May, Adlink announced the first MXM 3.1 modules with Nvidia Turing GPUs, ranging from the Quadro T1000 to the RTX5000. The company has followed up with the industry’s first MXM modules equipped with Nvidia’s higher-end Ampere graphics.

  • NXP's i.MX9 debuts with dual -A55, microNPU equipped i.MX93

    NXP unveiled a Linux-driven, energy-efficient “i.MX93” SoC for IoT with 1x or 2x 1.7GHz Cortex-A55 cores, 2D GPU, 250MHz Cortex-M33, NXP EdgeLock security, and options including a 1-TOPS Arm Ethos-U65 microNPU and Azure Sphere security.

    NXP announced the first of several i.MX9 processors, which offer improved security and power management and an optional 1-TOPS Arm Ethos-U65 microNPU. NXP’s first i.MX9 chip is a low-end i.MX93 model that focuses on energy efficient IoT applications, including battery-powered devices. The i.MX93 is equipped with 1x or 2x 1.7GHz Cortex-A55 cores, a 250MHz Cortex-M33, and an optional 1-TOPS, 256 MACs/cycle Arm Ethos-U65 microNPU.

    The i.MX93 is equipped with a 2D-only graphics GPU with support for up to 1080p60 encode and decode with MIPI-CSI and -DSI and 720p60 for LVDS and parallel interfaces. The GPU supports blending/composition, resizing, and color space conversion. Applications include voice-assisted smart home and building systems, low-power industrial gateways, and automotive driver monitoring systems.

  • NXP i.MX 93 processor combines Cortex-A55 cores with Ethos U65 microNPU - CNX Software

    NXP has unveiled the i.MX 93 processor family comprised of i.MX 935x, 933x, 932x, and 931x parts at this time with up to two Cortex-A55 cores, one Arm Cortex-M33 real-time core, as well as an Ethos U65 microNPU for machine learning (ML).

    We wrote about i.MX 9 family back in March with NXP telling us it would include an Arm Ethos U-65 microNPU and EdgeLock secure enclave, be manufactured with a 16/12nm FinFET class process, and includes the “Energy Flex” architecture to optimize power consumption by turning on/off specific blocks in the processor. The NXP i.MX 93 is the first family leveraging those new features, and we know have some more details.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
