  • Fair Code vs Open Source, Which Wins The Future?

    When developers release their software as open source, they are also giving a by-definition right to every company in the world to commercially use their software without having to obtain a license or share some profits with them. And this caused some problems in the open source world few years ago. For example, Amazon took the MongoDB source code (An open source database system), changed its name and then provided it as a SaaS (Software-as-a-Service) on its AWS platform, and then charged people money to use it. MongoDB developers were angered since they literally got nothing back from Amazon although they are the original creators of 100% of the code.

    This adds some sustainability problems to open source projects, as anybody and any company can just take the code and then reuse it commercially without giving anything back to the original developers. The original developers may starve and the project may stop, and there would be no obligation by anyone to commercially pay them.

    Fair code initiative arose from this context; To prevent anyone from using the software commercially without contacting the original software authors first, making it under the umbrella of what’s known as source-available models.

  • How to Convert a Project to REUSE Compatible License Statements?

    This blog post provides a step-by-step example about how the conversion of a project to REUSE compatible license statements is done in practice. For my setup, I have a readily configured kdesrc-build environment.

    First, I get out the most recent source code if the project I want to convert. For this tutorial, I use KTurtle, which is a nice and small application from KDE Education with just about 200 files.

  • John Cook: Descartes and Toolz

    I was looking recently at the Python module toolz, a collection of convenience functions. A lot of these functions don’t do that much. They don’t save you much code, but they do make your code more readable by making it more declarative. You may not realize need them until you see them.

    For example, there is a function partitionby that breaks up a sequence at the points where a given function’s value changes. I’m pretty sure that function would have improved some code I’ve written recently, making it more declarative than procedural, but I can’t remember what that was.

    Although I can’t think of my previous example, I can think of a new one, and that is Descartes’ rule of signs.

  • How big data forced the hunt for extraterrestrial intelligence to evolve

    Interest in SETI can be used to bring the public into science as well. A recent collaboration between the SETI Institute and the open-source software project GNU Radio aims to give people the opportunity to learn about radio engineering, digital signal processing, and radio astronomy. By purchasing a dongle for around $25, members of the public can digitize analog radio signals and process signals on their computers.

           

  • Getting credit: Taking your place in a meritocracy

    Dealing with either of those incredibly frustrating situations without appearing petty is difficult. But getting credit for your ideas and work is critical in today's organizational environments, especially those that aspire to be well-functioning meritocracies. Promotions, bonuses, and other forms of recognition (such as the opportunity to lead the project you proposed) are all generally based on performance. If people don't know you contributed, you'll likely be continually overlooked.

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.
