Act Sem 21-28Jul - PHP obsolete? - IntersectionObserver - Django Tailwind - Shopping and +

Welcome to another week where I'll be talking about all the updates I posted, corresponding to the week of July 21st through July 28th, which is the current date.

YouTube Channel and Blog Updates

Opinion: "Fewer tutorials, more action"
An opinion video where I analyze an article that encourages us to watch fewer tutorials, less Google, less AI (I might add). The message isn't to criticize resources, but to take action.

Watching tutorials is fine, but don't forget the official documentation, which should always be your primary reference. Some people think that by buying a course or book, they shouldn't have to read the documentation, and that's a big mistake. In addition to reading and watching, you have to create on your own.

Intersection Observer
I'm introducing a very interesting feature: the Intersection Observer, which allows you to observe a set of elements—for example, section titles—and, when they appear on the screen, execute an action.

In this case, I'm using it to highlight the active content next to it, giving the user a visual indication of where they are in the content. It can also be used for animations or other effects.

Tailwind Django
A video I really liked: how to integrate Tailwind into a Django project using the django-tailwind plugin. I also integrated the typography plugin.

I love this because it allows us to work with Node in a Django project, which is one of the great advantages I like most about Laravel, especially using Livewire. Laravel lets you choose your build system and, above all, has native integration with Node, something it's had for years.

In Django, although it's a bit more complex (at least for me), it can also be done. So it has a lot of potential.

Using AI with Laravel
I'll explain how you can use ChatGPT with Laravel, running a prompt from Laravel that communicates with the ChatGPT API and returns the response.

Command to view SQL
A command I loved but didn't know about: pretend. It allows you to view the SQL directly from the terminal, without executing it. This is useful if, for example, you're in production and can't access the terminal—typical on shared servers. This way, you can copy the SQL and execute it manually from another client.

Opinion: Technologies That Will "Die" in 2026
I analyze an article that says many technologies will be obsolete by 2026. My opinion:

PHP: I don't think so. It still powers half of the world's websites and is still actively being updated.

Ruby: It has a small community, but it's still alive.

Visual Basic, CoffeeScript, Perl: Yes, I consider them to be in decline.

Objective-C: Although Swift is replacing it, it's still used in legacy projects.

AIs aren't perfect, code suggestion issues
I had a problem with a setting using environment variables in Django. I wanted it to be defined only when necessary (in this case, to manage npm). If it wasn't defined, it should take a default value.

I set it to null, but it didn't work. I asked the AI, and it got lost in its responses. Finally, I solved it in the official documentation, where the default value was clearly specified. Again, it's important to check the official documentation.

Unreal Engine 5.4 vs 5.6
On another channel, I posted a video about the improvements in Unreal Engine 5.6 compared to 5.4, mainly focused on performance, which is always appreciated.

Course and Book: Django Shopping

Remember that Django Shopping is a translation and adaptation of the application we built with Laravel Livewire Shopping.

Most recent changes:

• We're starting with Django + Tailwind (video already published).
• Navigation tweaks using slots.
• Simple styles for product details, containers, images, and filters.
• Dark mode in progress.
• Goal: To make it as similar as possible to the version built in Laravel Livewire (although we use Flux in Laravel, so there will be minor differences).
