  • The weird world of non-C operating systems • The Register

    Believe it or not, not everything is based on C. There are current, shipping, commercial OSes written before C was invented, and now others in both newer and older languages that don't involve C at any level or layer.

    Computer hardware is technology yet very few people can design their own processor, or build a graphics card. But software is a form of culture. Open source is created by volunteers, even if they end up getting paid jobs doing it. Even rejecting open source is a choice: paying for Windows or macOS instead reflects a preference.

    This is especially visible when it comes to text editors, and even more so about programming languages. People get passionate about this stuff. So statements such as "C isn't a programming language any more" can be upsetting. Most people live and work in the cultures that are Unix and Windows and if they are all you've ever known, or know best, then it's easy to think they are the whole world.

  • Introducing Very Bad Web Application

    I am planning to add a few chapters on securing services in my Linux Command Line book. But, to make it practical & hands on, I needed one real application which the readers can deploy and secure. I needed something simple, say one single binary so that it becomes easier to convert it into a proper systemd service.

    I decided to write one in Rust Smile This also helps to showcase that one can write totally insecure code even in Rust (or any other language). Let me introduce Very Bad Web application. The README contains the build instructions. The index page shows the available API.

  • Debugging source is even harder when you can't stop laughing at it

    As was so often the case, the cards occasionally failed and had to be replaced. A manual card index was used to keep track of things as broken hardware arrived and working kit was sent out. It worked about as well as you'd imagine. "We were quite proud if we only lost a few items a month," said Philip, "but management weren't quite so impressed by our finely honed skill."

    However, the operations manager had contacts in the US and managed to secure the services of a student for six months. "Brad" (also not his name) would come to the UK on what Philip now reckons looked a bit like a modern zero-hours contract and do various work experience at the facility.

    "He was an enthusiastic employee and took it on himself to learn enough Visual Basic to make a rudimentary replacement to our card index."

    Like all too many quick and dirty Visual Basic/Access mash-ups of the time, it seemed to work pretty much perfectly after a few iterations. So much so that the business came to depend on Brad's work and the old manual filing system was filed in the bin. Brad eventually returned to the US, but the fruits of his labor lived on after his departure.

    "After some time – I forget what caused it – an update was required to Brad's hard work," recalled Philip, "and we, the lads who were reasonably proficient at working at code level, were asked to break open his source and make the change."

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.
