  • What Are the Differences Between Raspberry Pi and Arduino?

    Arduino hails from Italy, and it’s said that it was named after a bar where the developers usually meet to discuss the board. The first Arduino was developed in 2005 and aimed to provide students at Interaction Design Institute Ivrea in Italy with an inexpensive microcontroller board. Its cost and simplicity also piqued the interests of hobbyists and professionals; it wasn’t long until it reached a wider community of makers. Many other varieties of Arduino boards have been created since then. In 2013, around 700,000 Arduino boards were already sold [1].

    Raspberry Pi was born seven years after Arduino when Eben Upton invented a low-cost, modular, the single-board computer that will help improve the programming skills of his students. Like Arduino, it soon reached a wider audience due to its cost and versatility. The first Raspberry Pi board cost only $35, far less expensive than the existing computer boards that usually cost five times higher. The small board got even smaller and cheaper after the Raspberry Pi Foundation created the Raspberry Pi Zero, the smallest Raspberry Pi board to date, which costs only $5. Raspberry Pi progressed rapidly that millions of boards were already created from the initial target of just 10,000 boards years after its first release.

  • Arduino Blog » Homebrew Hakko 907 digital soldering station

    If you want to upgrade your soldering setup without spending a lot of money, then be sure to check out Angelo AKA TechBuilder’s DIY Hakko 907 station.

    This low-cost device features an Arduino Nano to read the iron temperature via an LM358 op-amp, and regulates power to the handle and tip under PWM control using an IRFZ44N MOSFET. A potentiometer is implemented as a variable temperature knob, with the actual and preset temperature displayed on a 16×2 LCD screen, while an LED indicates whether the heating element is active.

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.
