  • Bash If-Else statements with examples | FOSS Linux

    Conditional statements are the bread and butter of programming. They allow the machine to make decisions procedurally, through a process of elimination and repetition, almost making it act like it has its brain. Just a brain with a minimal amount of knowledge and no creative prowess (yet!) but functioning, nevertheless.

    Today, we will talk about one specific conditional statement: the if-else statement. We will show you how to write the syntax for Bash scripting and use its different variations.

  • from HTML5 & Javascript blob technique to ransomeware – JS is evil (when it is allowed to do more than gui animations)

    “The Duri malware, for example, uses the Javascript blob technique.

    The attacks are triggered by visiting a website with the malicious code.”

    (this could be a well known, sincere, but hacked website)

    “By downloading, the malware can install itself on the target device.”

    “HTML smuggling is also made possible by the HTML5 “Download” attribute for anchor tags.”

    “When a user clicks the HTML link, a download of the file is triggered.”

  • Introducing qmake2cmake

    Qt's own QMake project files have been converted with a Python script named pro2cmake that lives in qtbase. This script is specially tailored for converting the projects in Qt repositories and is little useful for converting user projects.

    We have forked this script and turned it into a converter for your projects: Say hello to qmake2cmake!

  • Make Your App Live Longer

    I could literally watch my technology deteriorating. My releases were always late. We had too many bugs. The UI felt old. That was when I used to head the R&D and product management of a cloud-based B2B solution. The solution used Java as the backend and Angular JS as the frontend UI framework. While the Java code was more than 15 years old, it performed well in the Docker containers. It was the UI framework I was worried about.

  • Qt for Python details on the new 6.3 release

    Finally the time has come! we are really excited to let you know everything we have been working on for this release so let's dive into the details

  • Github shenanigans

    It all started with a simple pull request [1] to fix a bug. I have never attempted to just “merge” a pull request on Github before, but I figured, with such a simple change [2], why not try? Why not indeed.

    Well, it broke my local repository. The commit message wasn't what I would have liked, and I felt a revision of the version number was required, which also involved updating the makefile and the Luarocks specification file [3]. I made the mistake (I think—I don't know) of ammending the merge message with a reformatted title and extra files and that was that. I was unable to push the changes back to Github.

    I ended up having to reset both my local repositories and the Github repository. Hard. As in with the `git reset --hard` nuclear option. And hand added the patch into the code, redid all the changes to the makefile and Luarocks specification file multiple times. Ugly stuff. But I got it as I like it.

    And then I went to load the new version of the code into Luarocks [4] and of course it failed. Of course. Github decided several months ago to depcrecate support for `git:` URL (Uniform Resource Locator)s [5] and guess what I'm using?

  • 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.
