  • Raspberry Pi Touchscreen Driver Finally Being Mainlined With Linux 4.21 Kernel

    Finally with the in-development Linux 4.21 kernel will be the input driver for supporting the Raspberry Pi 7-inch touchscreen. 

    Raspberry Pi has long offered an official 7-inch touchscreen monitor with 800x480 display that interfaces with the Raspberry Pi ARM SBCs via power from the GPIO and display via the DSI port. The touchscreen support 10-finger touch and other basic features but until now hasn't seen mainline kernel support.

  • Picovoice Puts Smarts Offline in 512K of Memory

    We live in the future. You can ask your personal assistant to turn on the lights, plan your commute, or set your thermostat. If they ever give Alexa sudo, she might be able to make a sandwich. However, you almost always see these devices sending data to some remote server in the sky to do the analysis and processing. There are some advantages to that, but it isn’t great for privacy as several recent news stories have pointed out. It also doesn’t work well when the network or those remote servers crash — another recent news story. But what’s the alternative? If Picovoice has its way, you’ll just do all the speech recognition offline.

  • Raspberry Pi gets official touchscreen support via Linux 4.21

    The official Raspberry Pi touchscreen will be supported in the mainline Linux kernel, as this Wednesday pull request by Google engineer Dmitry Torokhov provides support for the 7-inch, 800 x 480 display. The touchscreen has existed for several years, though prior to now, support was provided either by customized kernels for distributions like Raspbian-which specifically targets the Raspberry Pi-or by custom kernel patching.

    Though external displays typically do not require custom drivers, the Raspberry Pi touchscreen connects via the DSI port, rather than HDMI, with power provided via GPIO pins.

    aspberry Pi touchscreen will be supported in the mainline Linux kernel. On Wednesday, Dmitry Torokhov issued a git pull request that has added support for the 7-inch, 800×480 display in the mainline kernel for the official Raspberry Pi Touchscreen.

    Until now, touchscreen support was provided with the help of customized Linux kernels for Raspbian, a Debian-based OS meant exclusively for Raspberry Pi devices or using custom kernel patching.

  • 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.
