  • Everyone’s a (Perl) critic, and you can be too!

    The perlcritic tool is often your first defense against ​“awk­ward, hard to read, error-​prone, or uncon­ven­tion­al con­structs in your code,” per its descrip­tion. It’s part of a class of pro­grams his­tor­i­cal­ly known as lin­ters, so-​called because like a clothes dry­er machine’s lint trap, they ​“detect small errors with big effects.” (Another such lin­ter is perltidy, which I’ve ref­er­enced in the past.)

  • Structural pattern matching in Python 3.10

    In the meantime, I thought I’d get to know the feature better by writing up my thoughts and some code examples in article form. As you can gather, I’m rather biased, but I’ll try to present the positives as well as just criticism.

    The pattern matching feature has no fewer than three PEPs (Python Enhancement Proposals) to describe it: [...]

  • Emmanuele Bassi: Properties, introspection, and you

    It is a truth universally acknowledged, that a GObject class in possession of a property, must be in want of an accessor function.

    The main issue with that statement is that it’s really hard to pair the GObject property with the accessor functions that set the property’s value, and retrieve it.

    From a documentation perspective, tools might not establish any relation (gtk-doc), or they might require some additional annotation to do so (gi-docgen); but at the introspection level there’s nothing in the XML or the binary data that lets you go from a property name to a setter, or a getter, function. At least, until now.

    GObject-introspection 1.70, released alongside GLib 2.70 and GNOME 41, introduced various annotations for both properties and methods that let you go from one to the other; additionally, new API was added to libgirepository to allow bindings to dynamic languages to establish that relation at run time.

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.
