In this post, we'll learn how to create a ribbon (i.e. a toolbar) in Microsoft Excel.

We'll create our custom ribbon for an Excel file, save the ribbon in the file so our users will have a nice and intuitive interface to work with our worksheet.

But what a happy and strange coincidence. In its new version (4.26) released yesterday (on my birthday), Docker adds support for PHP with Apache to its docker init instruction. Let's see how this translates into a practical case.

Imagine you're a web developer or you work in a web agency and you'd like to keep an eye on the sites you've developed for your clients, free of charge. Are these sites online now, or are they down?

This work is carried out by site monitoring platforms. Could you install one on your computer? Of course!

For 1,000 reasons or more, you want to encrypt a file containing text. Which software should you install? Well ... none other than Docker!

By using a Docker Alpine/OpenSSL image, it's so easy to encrypt/decrypt files using OpenSSL.

Good old memories... During my studies (in 1991-1993), I was a huge fan of Turbo Pascal 7.0. It was the first language that I really learned and loves it so much. I used to spend dozens of hours behind my computer writing anything and everything.

If you good remember that time, Turbo Pascal 7.0 was used to create executables for MS-DOS.

The idea for this article came after the one written on assembly language: is it possible in 2023 to run Pascal code written 30 years earlier?

When I was young...er than today, during my studies, I was playing with the x86 Assembly language on my 386DX40 computer; this was in the years 1993-1995. The beginning of Windows 3.1 that I didn't like. If someone had asked me whether graphical interfaces would be successful, I would have said no, of course not.

I remember that I wrote a resident program (TSR for Terminate and Stay Resident) which, once loaded into memory, monitored the keyboard and recorded the keys that had been pressed in a file on the hard disk. And yes, it was a password stealer. Just for fun and, above all, for the challenge it represented.

And now, in 2023, I was wondering whether it was still possible to run .asm files on my computer. It was an excellent pretext for this article.

Remember a few years ago when you wanted to learn a new programming language such as Python? What did you need before you could even start programming your first Hello World? You had to install the language on your computer; maybe you also had to get a lot of libraries/dependencies; you had to spend time configuring your machine before you could even start writing your first script.

That's all over with the advent of Docker and the concept of containers.

This time, we'll play with Python for this article. I'm discovering Python at the same time as writing this article: at this precise moment, I've never written .py scripts.

In this post, we'll play with Docker and Java. Since there are ready-to-use Java images for Docker you don't need to install or configure anything other than Docker.

Filament is a collection of beautiful full-stack components. The perfect starting point for your next app. i.e. a set of free-to-use components and promises that we'll be able to quickly build nice administration interfaces.

The competitor of Filament is the official Laravel Nova which is a paid software.

Filament is built using the latest technologies: the TALL stack. This acronym sums up the technologies used: Tailwind, Alpine, Laravel and Livewire.

It's not something new, but it's probably not known well enough: by surfing on any Github repository like f.i. https://github.com/cavo789/blog, you can just press . (the dot key) on your keyboard to start vscode online i.e. see the current repository in vscode.dev.
