  • 10 Best Microcontrollers on the Market

    As with SBCs (single board computers), CPUs, GPUs, and other electronics on the market, microcontroller production has been impacted by the pandemic, leaving manufacturers with limited resources. That being said, the chip shortage is expected to end in the coming months, with replenished supplies following shortly after. Regardless of said shortage, manufacturers have released many new microcontrollers before the pandemic, along with some new revisions to popular platforms. In this roundup, we will take a look at some of the best microcontrollers and microcontroller boards for 2021.

    [...]

    The Arduino Uno has been around for the better part of a decade in one form or another and is used as the foundation for many great projects. The latest board, Arduino Rev3, uses an ATMega328p microcontroller, with 32Kb of Flash, 2K of SRAM, and 1K of EEPROM. The board packs 14X digital input/output pins (6 can be used as PWM outputs), 6X analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connecter, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; users connect it to a computer with a USB cable or power it via an AC-to-DC adapter or battery to begin building their projects.

  • Ubuntu Blog: The State of Robotics – March 2021

    It’s never too late to learn. As any reinforcement learning agent, we get rewarded by the new knowledge that we acquire. Likewise, we learn by doing, by rolling up our sleeves and getting to work. (Do you want a hands-on book on Reinforcement Learning? Here is my personal favourite)

    March has shown us great examples of this. From robots learning to encourage social participation to detect serious environmental problems, it was a learning month.

    [...]

    Last month we learned about Perseverance and Ingenuity. But NASA keeps developing new robots to explore Mars. Led by NASA JPL’s Team CoSTAR, they presented the results of the first Martian Analog testing with autonomous quadruped, referred to as Au-Spot.

    Perseverance is a wheeled rover. This limits the robot to flat, gently-sloping terrains and agglomerate regolith. Rovers cannot tolerate instability and operate within a low-risk envelope (i.e., low-incline driving to avoid toppling).

    Here is where legged robots have an advantage. NASA’s ‘Mars Dog’ is a four-legged robot capable of navigating through hard-to-access planetary surfaces. The robot has unique failure-recovery behaviours, providing a major breakthrough in planetary navigation.

  • Rugged, fanless quad-camera system brings AI and Machine Vision to rolling stock and automotive applications

    Eurotech BoltGPU 10-31 is a rugged fanless embedded system powered by NVIDIA Jetson Xavier NX module, equipped with four FAKRA connectors for GMSL camera, and designed to bring Edge AI and machine vision to rolling stock (e.g. trains) and automotive applications.

    The BoltGPU 10-31 also features 16 GB of eMMC flash, NVMe SSD support, three Gigabit Ethernet interfaces, WiFI 6 and Bluetooth 5.1, two USB3.1 ports, as well as isolated CAN-FD, optoisolated DIO, video out, and GNSS with optional RTK.

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.
