  • Ubuntu Blog: The‌ ‌State‌ ‌of‌ ‌Robotics‌ ‌-‌ ‌October‌ ‌2021‌ ‌

    October went fast, full of news and packed with interesting robotics applications. This month certainly doesn’t need an intro, so we will let the news take all your attention.    

  • 3.5-inch RK3399K SBC breaks out with mini-PCIe and dual M.2

    Kontron’s 3.5”-SBC-R39 board provides a 2.0GHz, hexa-core RK3399K with up to 4GB soldered LPDDR4, up to 32GB eMMC, 2x GbE, 5x USB, DP, HDMI 2.0, mini-PCIe, and M.2 B- and E-key slots.

    Rockchip’s RK3399 has been seen on several Pico-ITX boards based on Rockchip’s RK3399, such as IEI’s Hyper-RK39, and many smaller SBC’s such as the Orange Pi 4 and over a dozen others in our catalog of 150 Linux hacker boards. Now, Kontron has released what appears to be the first 3.5-inch model. The 146 x 105mm 3.5”-SBC-R39 offers a choice of standard RK3399 with dual 1.8GHz Cortex-A72 and 4x 1.4GHz Cortex-A53 cores or the RK3399K, which ups the clock to 2.0GHz and 1.6GHz, respectively. Kontron used the RK3399K on its fA3399 SMARC module.

  • Low-Cost Computer Gesture Control With An I2C Sensor | Hackaday

    Controlling your computer with a wave of the hand seems like something from science fiction, and for good reason. From Minority Report to Iron Man, we’ve seen plenty of famous actors controlling their high-tech computer systems by wildly gesticulating in the air. Meanwhile, we’re all stuck using keyboards and mice like a bunch of chumps.

    But it doesn’t have to be that way. As [Norbert Zare] demonstrates in his latest project, you can actually achieve some fairly impressive gesture control on your computer using a $10 USD PAJ7620U2 sensor. Well not just the sensor, of course. You need some way to convert the output from the I2C-enabled sensor into something your computer will understand, which is where the microcontroller comes in.

  • 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.
