  • Thunar, GtkAction and a big mess

    My journey into the GtkAction abysses of Thunar began in the mid of 2019. Be warned, it is no story of success. It is rather a story about finding a way through a maze while walking into almost every dead end.

    Actually I just wanted to fix #198 (Merge all file-context-menus into one). But somehow things got weird. More than half a year later and after numerous interactive rebases I finally merged my branch into master \o/

  • GNU Guile 3.0.4 released

    We are pleased but also embarrassed to announce GNU Guile 3.0.4. This release fixes the SONAME of libguile-3.0.so, which was wrongfully bumped in 3.0.3. Distributions should use 3.0.4.

  • The Python heapq Module: Using Heaps and Priority Queues

    Heaps and priority queues are little-known but surprisingly useful data structures. For many problems that involve finding the best element in a dataset, they offer a solution that’s easy to use and highly effective. The Python heapq module is part of the standard library. It implements all the low-level heap operations as well as some high-level common uses for heaps.

    A priority queue is a powerful tool that can solve problems as varied as writing an email scheduler, finding the shortest path on a map, or merging log files. Programming is full of optimization problems in which the goal is to find the best element. Priority queues and the functions in the Python heapq module can often help with that.

  • It’s Time to Start Learning Coding: Top 20+ Best Websites To Learn Programming in 2020

    I’m sure many of us are wondering how to stay a relevant professional in the post-pandemic world. One of the ways, obviously, is learning to program. Now that the industry is at the 21% growth rate (higher than that of any other field), it’s clear that the demand for good developers is not going anywhere.

    Moreover, it’s likely to grow in the next couple of years, as more businesses will consider replacing physical processes and practices with the digital ones.

    In this post, you will find out why now is the time to master coding and collect a complete resource deck to fuel your progress — over 20 websites that help future coders get better at their jobs.

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.
