“Autopsy of a binary crime” Investigation (and solution) when you have two #Docker containers; one needs to connect to the first and it doesn't work.

In my new article, I discuss a range of technologies for creating #reveal.js-style slideshows. I suggest creating a #Quarto-based #devcontainer #docker that allows you to write your presentations with little use of the mouse. Bye #PowerPoint! Here an example of such slideshows: docker.avonture.be

In my new article, let's optimize the basic #Docusaurus rss.xml for content aggregators. The default output often lacks the header image, full content, author and language tag. We'll enhance the file to ensure a richer user experience in newsreaders.

Unless you live on another planet, you too have seen the flood of information about #Zorin OS, which claims to replace Windows 10. Tested and approved. It is easy to install, and the interface is so similar to Windows that even grandma should be able to use it successfully.

Absolutely essential for any self-respecting geek: how to inject ASCII art into the source code of each #Docusaurus page. Let's see how to create a #plugin that will be called by Docusaurus while rendering the HTML version of your site.

New ReactJS component for #Docusaurus that allows you to display a changelog (latest changes) on articles.

I've added a /src/data/series.js metadata to my series #Docusaurus component to be able to provide a description and a custom image to a series. www.avonture.be/series/

How I did to refactor my #Docusaurus blog using #Docker to setup a fast production image and a development one (using #VScode #DevContainer), enabling an editable environment with pre-loaded extensions and tools like #LanguageTool for content quality checks, #cspell or #markdownlint.

I have updated the image of my #Docusaurus blog on #Docker Hub. If you want to try it out: in a DOS or Linux console, run “docker pull cavo789/blog” then “docker run -d -p 443:443 --name blog cavo789/blog.” Wait a few. Open a browser and go to localhost, and voilà, my blog is running offline. 🐋🐋

Let's see how to create a static website using #VSCode and #Docker. The #devcontainer will be based on an image of the #Quarto software. Everything will be preconfigured so that all you have to do is write your website from VSCode, and hot reload will allow you to see the changes in real time.

In the professional world, there are still #MSAccess databases everywhere, created by business users with little or no technical skills. The last time I was called in to help because the database was slow and under-optimized, I created a tutorial to enable users to optimize their other databases.

If you are or have been a #VBA programmer for Excel, here is a script that allows you to extract the code from modules as text files. The idea is to take a backup and send them to #GitHub, for example, for code versioning.

#CaesiumCLT is a Linux batch image optimization program. For my part, I foolishly used the png format to take screenshots, which were then included in my articles. Compressing and saving them in #webp format without any loss of quality resulted in a 90% gain in file size—huge!

How should you structure your program to have a #Docker image for production and, when working locally, extend it with development tools (#devcontainer)? In this article, let's see how to proceed. One image for the deployment and, locally, using VSCode and the devcontainer feature.

Can tasks be executed in parallel using a #linux #bash script? Yes! You can launch multiple processes, wait for them to finish, and start new ones. When you need to manage thousands of input files to, f.i., check data quality, process them, download them somewhere, this tip will boost your script.

How to write a #progressbar in a #bash shell? In my use case, I need to download and process one or more zip, they'll contains one or till thousands of csv files. How to show the progression to the user? With a progress bar for sure; even in a #linux script.

When you launch several different tools with #Docker, you get several independent containers, meaning that with the Docker Desktop tool, you see them as if they were "files" (easy comparison). In my case, I like to group them by “folder”: my ‘tools’ in a “tools” folder. Can this be done with Docker?

When a #Docusaurus technical blog post was written a year or more ago, perhaps some things are no longer entirely relevant; versions may have changed, a particular tool may generate a deprecation notice, or something else may have happened. Let's display a banner to inform the reader.

Over the last few days, I've redone all the images on my blog using Google Nano Banana, where you can upload one or more images, ask it to isolate one or more characters, include one or more logos, etc. and generate a new image that uses the same style as the others. In short, it's incredibly easy.

Learn how to start a HTML site with #Docker in just one CLI. Even using MS-DOS.

#Docusaurus Build a dynamic #Snippet component that auto-updates code from your source files, ensuring your articles are always current and impactful. Thanks to @docuxlab.com for his LogoIcon component.

Creation of a #Docusaurus plugin to perform Search&Replace, i.e., during the HTML code generation phase of the site, replace certain defined values with another string of characters. One could imagine a snippets-type use case for this i.e. you put things like $CLIENT_ID$ and replace it on-the-fly.

Updating my #Docusaurus tips article by adding a chapter about the #Highlight React component.

Adding a #ScrollToTopButton feature on my #Docusaurus website. Now, a nice meerkat will be displayed during the vertical scroll on long articles. Just click on it and you'll jump back to the top with a smooth animation. React component created by @docuxlab.com

When you're already using #Docker and #vscode , you can code inside a #devcontainer. You'll open your project with VSCode but everything will already be configured for that specific project: extensions, configuration, tools (like enabling XDebug here).

List of #CodeQuality tools I'm using for #Python 1. Pylint 2. Autoflake 3. isort 4. vulture 5. pydocstyle 6. mypy 7. Pyright 8. Black 9. prospector 10. Extra - Ruff

My new #Docusaurus component (and plugin) to be able to create a list of articles as part of a series. Also, create a /series and /series/:slug pages to promote them. Creating series will allow authors to cut off very big articles in smaller ones, increase SEO and it's more professional, no? ;)

Overriding the native #Docusaurus tags page to display articles as cards; much nicer when there are a large number of articles. The Cards component is the one of @docuxlab.com Learn how to proceed by reading my latest article.

Because this doesn't exist natively in #Docusaurus, I created a React component called RelatedBlogPosts that displays related articles. It increases the interest of each post (and their visibility) when a visitor comes for a specific post and sees that there are other things that may interest them.

After #Behat, after #Cypress let's play with #Pest and write some browser tests. Such functional tests will allow you to automate actions on your website like navigating, filling in forms, ... and do assertions like checking DOM elements. In this article, let's do everything in #Docker. No config.

Introduction to #Behat which is a PHP framework to allow functional tests on your website. Behat is perhaps quite old now (but still working). Let's see in deep how to implement it and make some checks .

A quick and easy way to override how #Docusaurus will translate a  Markdown notation to a <img> HTML tag. No need to code. We just need to add our override in the #MDXComponents file.

My third part of the series "How to create a #Joomla site using #Docker". In this last step-by-step tutorial, let's see how to restore a #jpa archive using Docker. Like this, just take a backup of f.i. a customer site using Akeeba Backup then download the JPA and tadaaa; it's piece of cake.

My second part of the "How to create a #Joomla site using #Docker"

How to create a #Joomla site using #Docker. A full step-by-step tutorial in three parts. The last one is to learn how to restore an existing backup (a #jpa file) and getting his site in minutes without to install all the stuff; just Docker.

Using IA, I've created a #docusaurus component to display CLI in a blog post using a #terminal look&feel. Feel free to reuse in your own projects. github.com/cavo789/blog...

I've also created a page where all my public repositories can be retrieved with searching and filtering options

In this #docusaurus post, learn how to create a #react Image #component then, too, a #plugin so we can replace images in all articles (250 in my case) and use the newly created component. At the end, we're overriding how Docusaurus creates <img> tags (but skipping blog post introduction image).

Second part of the #BlueSky component for #Docusaurus. We'll learn how to retrieve comments, likes and reposts of a BlueSky post and display them on the website. This is a step-by-step tutorial.

Adding a RelatedBlogPosts #docusaurus component on my site. Online example here: www.avonture.be/blog/docker-...

Playing with #python #fastapi and create a Jokes API. Simple illustration of how easy is FastApi.

From now, when I need to #ssh to my server, I just type `ssh MyAmazingApp` i.e. I should not remember the IP or the server name; just my application. And to get things easier, I just type ´ssh ` then TAB to get the list of ... suggestions. #Autosuggestions #zsh

Load a dropdown in a custom #ribbon in #Excel using a range. A pratical example would be: you'll have filters defined as ranges in a worksheet then use these values in a ribbon to get a nicer interface for your end users.

How to install #heimdall using #Docker to get a nice #dashboard easily. Really useful to gather links to your favourite tools.

My first #Docusaurus component in #React to interact with #BlueSky. In this first part, we'll learn how to create a component to display a "Share on BlueSky" button. In a second article to come, we'll also retrieve the list of likes, reposts and comments from BlueSky.

Can someone confirm to me the BlueSky features I've added on my blog are working. Here an example page: www.avonture.be/blog/excel-f... Did it works for you too? Can you go to a recent article where "No comments yet on BlueSky" is displayed and add a comment to see if it appears after a refresh?
