  • A practical guide to learning awk

    Of all the Linux commands out there (and there are many), the three most quintessential seem to be sed, awk, and grep. Maybe it's the arcane sound of their names, or the breadth of their potential use, or just their age, but when someone's giving an example of a "Linuxy" command, it's usually one of those three. And while sed and grep have several simple one-line standards, the less prestigious awk remains persistently prominent for being particularly puzzling.

    You're likely to use sed for a quick string replacement or grep to filter for a pattern on a daily basis. You're far less likely to compose an awk command. I often wonder why this is, and I attribute it to a few things.

  • What is your take on checking return values?

    Around this time, I think I said something about how that's basically the job. That is, my job, their job, anyone's job... is to check for things that could go wrong and deal with it when it does. It's never been optional, and certainly not because of some kind of "avoid messiness" mandate (where the heck did that come from, anyway).

  • IAR Build Tools for Linux improves integration from development to building and testing

    IAR Systems, a supplier of software tools and services for embedded development, has announced a significant update of its build tools supporting implementation in Linux-based frameworks for automated application build and test processes.

    [...]

    With the addition of the static analysis tool C-STAT, developers will be able ensure code quality throughout the development and testing process, according to IAR. C-STAT proves code alignment with industry standards like MISRA C:2012, MISRA C++:2008 and MISRA C:2004, and also detects defects, bugs, and security vulnerabilities as defined by CERT C and the Common Weakness Enumeration (CWE).

    “This latest version of our build tools for Linux enable our customers to make their testing and building processes more efficient as well as achieve code quality all the way,” said Anders Holmberg, General Manager Embedded Development Tools, IAR Systems. “IAR Embedded Workbench and IAR Build Tools improves performance and ease of use for more efficient workflows. Our broad offering enables companies to standardize on our tools and gain flexible workflows, and through this enhance productivity and collaboration between different teams in the organiSation.”

    The build tools for Linux includes the highly optimising IAR C/C++ Compiler, IAR Assembler, Linker and library tools, IARBuild and runtime libraries. The tools also support the integrated static code analysis tool C-STAT.

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.
