Programming Leftovers: Bash, Qt, Dylan and JavaScript

  • Take control of your data with associative arrays in Bash

    If you've ever written code, whether it's a shell script, a Python script, C++, or even Scratch, then you know that variables are vital. Computers and coders use variables as waystations, where they surreptitiously pass information back and forth. For instance, if you need to process a user's name in a shell script, you might set up a variable, put the username into the variable, and then instruct the computer to do something to the variable (check it against a list of authorized users, for example). Variables are important because they enable code to by dynamic: they're placeholders for information that's expected to change every time you run the code.

    But variables, because they're so common, can also become rather unwieldy. Often times, you gather so many variables in a code project that it's next to impossible to keep track of them all. You can use clever conventions, such as prefixing all related variables with a common string (user_name, user_pass, user_time, and so on), or you can create a master list of them somewhere for easy reference, but the overhead of keeping track of it all can becoming taxing.

  • Qt Online Installer 4.0 pre-alpha released

    We are proud to announce the release of Qt Online Installer and Maintenance Tool 4.0 pre-alpha. A lot of work has been done to improve the overall user experience of the new installer. A new Command Line Interface (CLI) makes unattended installations more straightforward compared to limited CLI and install scripts, used in Installer 3.x versions. The emphasis has been on the CLI improvements, but there have been changes to make the GUI more intuitive to use as well. The next step will be to continue GUI improvements to provide a pleasant install experience for all users.

  • Excellent Free Tutorials to Learn Dylan

    Dylan is a multi-paradigm programming language that includes support for functional and object-oriented programming (OOP), and is dynamic and reflective while providing a programming model designed to support generating efficient machine code, including fine-grained control over dynamic and static behaviors.

    Dylan uses an algebraic infix syntax similar to Pascal or C, but supports an object model not unlike the Common Lisp Object System (CLOS).

    It was created in the early 1990s by a group led by Apple Computer.

    Here’s our recommended tutorials to learn this language.

  • Create No-JavaScript friendly sites

    Because most trackers use JavaScript to track you, a lot of people block JavaScript on their browsers using different software in order to do that.

    If you want everybody to be able to read your website, and use your navigation, you should not make it in such a way that it will depend on JavaScript to work.

  • 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.
