Genymotion🕵‍♂️️?

When we talk about emulators, we mainly expect to talk about “Android Studio”, personally I don’t like Android Studio because I find it heavy and slow under my computer which makes me less productive.

Funnily enough, I don’t think I’m the only one, if you agree, please feel free to applaud this article 😅️.

for a long time I started looking for a better alternative and bingo I found “Genymotion” 💌️.
It is lighter and more powerful than Android Studio Emulators

You can download it for free on this link and follow all the installation process, sorry guys it’s not the purpose of this article show you how to install Genymotion Desktop…

Dart 🐦?

Dart (originally called Dash4) is a web programming language developed by Google. Its original purpose is to replace JavaScript to become the new lingua franca of web development, however, the current focus of developers is that Dart code can be converted to JavaScript code compatible with all modern browsers, as well as multi-application development.

Dart can also be used for server-side programming as well as mobile application development (via the Flutter API).

Dans cet article, je souhaite explorer certains des concepts de base de Django, en mettant en place une application Web minimale pour mieux comprendre le fonctionnement de Django sous le capot.

Un important avertissement avant de commencer, ce n’est pas un tutoriel sur la façon de démarrer une application Django, c’est plus une expérience exploratoire à des fins d’apprentissage.

introduction

Si vous lisez cet article, il y a de fortes chances que vous sachiez déjà que Django est un framework Web écrit en Python. Mais c’est une définition abstraite. En pratique, Django est un paquet Python qui réside dans le répertoire site-packages de votre installation Python actuelle. …
