  • Elevate is a walkable pin array floor that generates shape-changing terrains for VR | Arduino Blog

    Virtual reality technology has come a long way in the last decade, but there are still some major things that could be done to make it even more interactive and immersive. For one, what if VR users could actually feel the ground they walk on rather than simply see it? A team of students from KAIST in South Korea and the University of Chicago set out to tackle this by creating a fairly large 1.8 by 0.6 meter platform that can accurately create the feeling of varied terrain. Called the Elevate, this device uses a total of 1,200 pins that can individually raise and lower with 15mm of resolution.

  • Wind River Delivers Cybersecurity and Anti-tamper Protections for Mission-Critical Intelligent Systems | Wind River

    Wind River®, a global leader in delivering software for intelligent systems, today announced security enhancements to Wind River Studio, a cloud-native platform for the development, deployment, operations, and servicing of mission-critical intelligent systems. Studio enables companies to meet rigorous cybersecurity and anti-tamper requirements, further helping secure devices and systems through development, deployment, and operations.

    The steep rise in security threats shows a concerning trend. As new devices become connected, each represents a point of entry that can be exploited by a cyberattack. In 2020, IoT devices were responsible for 32.72% of infections observed in wireless networks, more than twice that in 2019.(1) Industries with higher dependency on software and intelligence-based systems will need to start demanding that security be addressed at every step in an intelligent system’s lifecycle.

  • Beelink GKmini Review – An Intel Celeron J4125 mini PC reviewed with Windows 10 Pro, Ubuntu 20.04

    When reviewing mini PCs I typically look at their performance under both Windows and Linux (Ubuntu) and compare them against some of the more recently released mini PCs. Since the start of 2021, I review using Windows 10 version 20H2 and Ubuntu 20.04 LTS and test with a selection of commonly used Windows benchmarks and/or equivalents for Linux together with Thomas Kaiser’s ‘sbc-bench’ which is a small set of different CPU performance tests focusing on server performance when run on Ubuntu. I also use ‘Phoronix Test Suite’ and benchmark with the same set of tests on both Windows and Ubuntu for comparison purposes. On Ubuntu, I also compile the v5.4 Linux kernel using the default config as a test of performance using a real-world scenario.

    Prior to benchmarking, I perform all necessary installations and updates to run the latest versions of both OSes. I also capture some basic details of the device for each OS.

  • 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.
