This is a very common source of problems using .env files: you've two or more different .env file like .env and .env.example.

You're a programmer and coding a new amazing feature. You're adding one or more new environment variables to your local .env file and everything is working fine on your computer.

Why? Because the variable(s) you've added have been added in your local .env file, on your computer only.

As you know, you have to create the variables in the .env.example file too but let's be honest, nobody thinks about it.

When deploying a project on servers, we need to pay particular attention to the .env file. This file is crucial and will determine whether our application works properly (or crashes).

The normal way of doing things is to run a git clone command to get the latest version of the application from a repository (branch test for a test server, dev for an acceptance server, main for a production server).

Once cloned, the next command will be to create the .env file and it's done using cp .env.example .env.

And that's where the obligation to be meticulous begins.

Today, I was facing (once more) with the following need: I need to update a setting in a text file but if the variable is not yet present, I need to add it.

So, in short, I need to make a search and replace or insert new line.

Using sed it's quite easy to automate the search & replace but how to append?

More than once I've found myself in the situation where I've got a site saved in the WinSCP configuration where I've saved the password and, um, gosh, what was it?

Did you know WinSCP provide an option to show you, in plain text, a stored password?

How many times have you modified a file in vscode (and forgotten to save the modification) in order to refresh it from your web page, run the script from your console, etc., and then thought Oh no, damn, it still doesn't work?

And it can take several minutes and back and forth before, damned, silly me, I didn't save my modification.

And even more so when you've done a Search&Replace in several files; some having been saved and others not.

Let's see how to avoid this.

Docusaurus didn't provide an easy way to retrieve the number of blog posts but there is well a trick.

There is an automatic page called archive like /blog/archive/.

On that page, all blog posts are displayed by year and months. With a document.querySelectorAll console instruction it's possible to make the count as suggested on https://github.com/facebook/docusaurus/discussions/9712

My use case is: I need to write some technical, long, documentation where I need to provide some information like IP addresses of used servers, some paths to the application, configuration folders, ...

The normal way to do this is to just put information directly in the documentation and to make sure to update every occurrence in case of changes during the lifecycle of the application.

The best way is probably to use an external file where information are stored in a key-value form and, during the rendering process of Quarto, replace short codes by values.

The Quarto reveal.js documentation is the best place to find instructions for creating impeccable reveal.js presentations.

In this article, we'll take a quick look at a few tips and tricks to make your reveal.js presentations even better.

When you're working with Linux (also working with WSL thus), there are many ways to personalize your prompt. One of the simplest solutions is to use Powerlevel10k and its wizard.

In this article we're going to use a Docker container just to : test and discard. The Docker container will only be used to install Powerlevel10k, configure it and play with it. After that, it's up to you to see whether you like the interface and, if you do, to redo the installation on your machine rather than in Docker.

The tip comes from here

The docker inspect command is used to retrieve detailed information about various Docker objects, including images, containers, volumes, networks, and nodes. It provides a comprehensive overview of the object's configuration, state, and other relevant details.

The returned information is a JSON representation of the object.

One use case is to be able to retrieve the name of the network used by a given container.
