Implementing Webpack from Scratch, But in Rust – [3] Using NAPI-RS to Create Node.js Addons

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, rust, software, webpack

Referencing mini-webpack, I implemented a simple webpack from scratch using Rust. This allowed me to gain a deeper understanding of webpack and also improve my Rust skills. It's a win-win situation! Code repository: https://github.com/ParadeTo/rs-webpack This article corresponds to the Pull Request: https://github.com/ParadeTo/rs-webpack/pull/4 The title seems unrelated to this series, as implementing webpack with Rust involves Node.js plugin development. But don't worry, let me explain. When we use webpack for bundling, don't we often run the following command? webpack --config webpack.config.js Enter fullscreen mode Exit fullscreen mode Similarly, we want our RS Webpack to support such a command. But how can…

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, ionic, ios, jitsi, mobile, software

Me llego un requerimiento sobre una aplicacion de desarrollo hibrido, esta es la misma para la que desarrolle el uso de los datos de salud, en este caso el requerimiento solicitaba que se implementara el servicio de videollamadas donde pueda ser usado para comunicarse indistintamente el sistema operativo iOS, Android y Web. Comence revisando las soluciones entre ellas dos: 1. Uso de WebRtc y STUN server, la implementacion representaba la configuracion de un nuevo servidor y desarrollo altamente complejo, cosa que me entusiasmo mucho; 2. Usar un iframe, como la implementacion por parte de la documentacion demostraba mayor facilidad de…

Understanding Error Handling: From Try-Catch to Result Types

stp2y0 CommentsNewscoding, community, development, engineering, inclusive, software

Introduction Error handling is a fundamental aspect of writing reliable software, yet many developers find themselves struggling with different approaches across programming languages. Whether you're coming from a try-catch background or exploring functional programming's Result types, understanding these patterns can significantly improve your code quality. 1. The Traditional Approach: Try-Catch Most developers start their journey with try-catch blocks, a familiar pattern in languages like Java, JavaScript, and Python. Let's look at how this works: try { const data = JSON.parse(userInput); processData(data); } catch (error) { console.error("Failed to process data:", error.message); } Enter fullscreen mode Exit fullscreen mode Why Try-Catch? Intuitive…

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…

My Experience with GitHub Copilot

stp2y0 CommentsNewscoding, community, development, dotnet, engineering, githubcopilot, inclusive, python, software, webdev

Hello,I'm Duke and I recently dove into using GitHub Copilot, and I’ve got to say, it’s been quite an adventure! I integrated it with a couple of languages—Python and .NET—and tried it out on several popular IDEs, including VSCode, Visual Studio, Rider, and PyCharm. Here’s a rundown of what I found during my experiments. Setting It UpGetting GitHub Copilot up and running wasn’t too tricky. However, if you’re using Visual Studio, make sure you’re on version 17.10 or later (2022). It’s a little bit of a hurdle if you're on an older version, but once you get through that, you’re…

BUILDING A CYBERSECURITY DETECTION AND MONITORING LAB BY LEVERAGING LOCAL VIRTUAL MACHINES (VMs) AND MICROSOFT AZURE

stp2y0 CommentsNewscoding, community, cybersecurity, development, engineering, homelab, inclusive, networking, security, software

Introduction Learning and implementing cybersecurity concepts can be challenging without access to practical and secure infrastructure. These challenges are further complicated by budget constraints that limit the acquisition of necessary hardware resources. To overcome this, this home lab guide provides instructions for provisioning, configuring, optimizing, and securing IT infrastructure using a combination of local virtual machines (VMs) and cloud resources for practical use cases. This approach enables deploying less resource-intensive tools on local VMs while leveraging the cloud for more demanding applications. It simulates both on-premises and cloud environments. The knowledge gained here can aid in production and large-scale, enterprise-level…
