Quando desenvolvemos uma aplicação web localmente e queremos compartilhá-la para testes ou demonstrações, encontramos uma barreira comum: a aplicação só está acessível em nossa rede local. É aqui que entra o ngrok! O Que é Tunelamento? O tunelamento permite expor um servidor local para a internet através de um canal seguro. Isso é especialmente útil em ambientes de desenvolvimento, onde você deseja compartilhar seu servidor com clientes ou testá-lo em outros dispositivos sem ter que fazer o deploy completo. Por Que Usar o Ngrok? O ngrok é uma das ferramentas mais populares para tunelamento, e por boas razões: Rápido e…

Análise de Sulco de Pneus com Inteligência Artificial em Python!

stp2y0 CommentsNewsai, coding, community, development, engineering, inclusive, programming, python, software

A análise de sulcos de pneus é uma tarefa crucial para identificar o desgaste e garantir a segurança, especialmente em veículos que percorrem longas distâncias. Com o uso de Inteligência Artificial (IA) e Python, podemos automatizar esse processo de maneira rápida e precisa. Aqui, mostramos como um modelo de rede neural convolucional (CNN), baseado na arquitetura VGG16, classifica pneus em "novos" ou "usados", enquanto o OpenCV ajuda a analisar as imagens para medir a profundidade dos sulcos. Tecnologias Usadas Python:Linguagem de programação popular para IA e Machine Learning, especialmente por suas bibliotecas avançadas. OpenCV: Usado para processar as imagens, detectar…

A Simple, mostly CSS code editor

stp2y0 CommentsNewscoding, community, css, development, engineering, inclusive, javascript, programming, software, webdev

In this article, I'm going to talk about how to make a very simple, browser based code editor using mostly CSS. I originally built this when I needed to let users edit JSON in a CMS that I was building. If you just want to jump to the code and the working example, here you go. The code can be found here and the working example here Contenteditable sucks... So if you were ever pondered building your own code editor, you have probably looked at contenteditable. While contenteditable is great for many situations, there is one huge problem in regards…

Mastering runCatching in Kotlin: How to Avoid Coroutine Cancellation Issues

stp2y0 CommentsNewsandroid, basic, coding, community, development, engineering, inclusive, kotlin, programming, software

The runCatching function in Kotlin is a powerful tool that lets you handle exceptions within a block of code while preserving the result. However, when working with coroutines, runCatching can introduce unexpected issues. Because it catches all exceptions, including CancellationException, it can interfere with proper coroutine cancellation. In this article, we’ll explore how runCatching works, its potential pitfalls in coroutines, and how to build custom Result extensions to handle exceptions safely without impacting cancellation. What is runCatching? runCatching is a utility function in Kotlin that executes a block of code and wraps the result in a Result object. If the…

This is why i hate project based learning

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, programming, software, webdev

I've been programming for about two years at university, but I've been coding since before then. I used to think that project-based learning was the best way to learn quickly—after all, it teaches you to build things in a "real" and fast way. But over time, I've come to realize that this approach has its downsides. The Problem with Project-Based Learning In project-based courses, you often end up building the same type of projects as everyone else, following similar tutorials and structures. This means you’re learning how to build the same things that thousands of others are building, rather than…

Abstraction: Decoding Abstract Classes in Java

stp2y0 CommentsNewsbeginners, coding, community, development, engineering, inclusive, interview, java, programming, software

In this post, we explore Abstract Classes, an essential part of abstraction in Java. We'll build on concepts discussed earlier and examine how abstraction simplifies complex systems. Abstract classes serve as a blueprint for other classes, allowing us to focus only on relevant details while hiding unnecessary complexity. Let’s dive deeper into what abstract classes are, why they exist, and how they are used. What is an Abstract Class? An abstract class is a class that cannot be instantiated on its own. It’s designed to be extended by subclasses that provide concrete implementations for its abstract methods. In other words,…

Representing and Manipulating Information in modern computer – Part 1

stp2y0 CommentsNewsc, coding, community, computerscience, development, engineering, inclusive, machinelevel, programming, software

As most of you might already know computer can only understand, store and process on a bit(0 and 1). But why?Well it turns out, two-valued signals can readily be represented, stored, and transmitted easily and more reliably than traditional base 10 number representation — for example, as the presence or absence of a hole in a punched card, as a high or low voltage on a wire, or as a magnetic domain oriented clockwise or counterclockwise, etc. Morever, a single bit is usually not very helpful in representing anything meaningful in computer but once we combine a sequence of bits,…
