  • How an affordable open source eye tracker is helping thousands communicate

    In 2015, while sat in a meeting at his full-time job, Julius Sweetland posted to Reddit about a project he had quietly been working on for years, that would help people with motor neurone disease communicate using just their eyes and an application. He forgot about the post for a couple of hours before friends messaged him to say he'd made the front page.

    Now three years on Optikey, the open source eye-tracking communication tool, is being used by thousands of people, largely through word of mouth recommendations. Sweetland was speaking at GitHub Universe at the Palace of Fine Art in San Francisco, and he took some time to speak with Techworld about the project.

    [...]

    Originally, Sweetland's exposure to open source had largely been through the consumption of tools such as the GIMP.

    "I knew of the concept, I didn't really know how the nuts and bolts worked, I was always a little blase about how do you make money from something like that... but flipping it around again I'm still coming from the point of view that there's no money in my product, so I still don't understand how people make money in open source...

  • Code Review--an Excerpt from VM Brasseur's New Book Forge Your Future with Open Source

    Even new programmers can provide a lot of value with their code reviews. You don't have to be a Rockstar Ninja 10x Unicorn Diva programmer with years and years of experience to have valuable insights. In fact, you don't even have to be a programmer at all. You just have to be knowledgable enough to spot patterns. While you won't be able to do a complete review without programming knowledge, you may still spot things that could use some work or clarification.

    If you're not a Rockstar Ninja 10x Unicorn Diva programmer, not only is your code review feedback still valuable, but you can also learn a great deal in the process: Code layout, programming style, domain knowledge, best practices, neat little programming tricks you'd not have seen otherwise, and sometimes antipatterns (or "how not to do things"). So don't let the fact that you're unfamiliar with the code, the project, or the language hold you back from reviewing code contributions. Give it a go and see what there is to learn and discover.

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.
