  • Quad GPIO Expander for Raspberry Pi Pico adds battery, display module, sensors, etc... - CNX Software

    People are normally using MCU boards for their low cost, low-power consumption, low price and/or real-time ability. The Raspberry Pi Pico is no exception, but if you don’t care about using a large board, Waveshare created a 177 x 62 mm “expander” board for the Raspberry Pi Pico that can take four modules.

    The company’s Quad GPIO Expander board includes a set of female headers for RPi Pico, and four sets of 2×20 male headers for extra modules that bring support for 14500 batteries, OLED displays, RTC, relays, and other compatible modules.

    The "x86/misc" pull request this morning for the newly-opened Linux 5.13 merge window adds the new KCPUID utility contributed by Intel.

    KCPUID is being added to the Linux kernel source tree by Intel for reporting CPU features as an alternative to the likes of /proc/cpuinfo. KCPUID s a utility to live within the kernel source tree for reliably reporting raw CPU features where as /proc/cpuinfo can sometimes misreport if features were disabled at boot-time and prior to new feature bits being added for /proc/cpuinfo reporting.

  • Rakudo Weekly News: 2021.17 Releastable

    Alexander Kiryuhin has announced the Rakudo Compiler 2021.04 Release. A little later than originally planned, because some issues were discovered that needed to be fixed, either in core or in the ecosystem. Kudos to Alexander and all the other people that worked on this release!

    This release comes with new IO::Path methods, and support for Julian Dates in the DateTime class, and a now term that is 38x as fast. Also many stability and speed improvements and other assorted features and fixes.

  • 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.
