Deno 1.9, introduces an exciting new feature for developers working with JavaScript and TypeScript: native HTTP/2 server capabilities. The update integrates a fast, Rust-based HTTP implementation to enhance performance and support the HTTP/2 protocol, which is a significant improvement over the previous HTTP 1.1-only support. This update marks a step forward in Deno’s evolution as a secure and efficient runtime for modern web applications. To build the new HTTP/2 server, the Deno team turned to hyper, a high-performance HTTP implementation written in Rust. This choice was made to improve the overall efficiency and speed of the Deno runtime, which has…

Microsoft’s return to the Java ecosystem marks an intriguing chapter in the company’s long history with the programming language, one that began with a memorable 1996 April Fool’s prank. Back then, Microsoft distributed empty boxes for a fictitious product called “Microsoft Coffee,” a supposed Java development tool. Little did anyone know, Microsoft was already working on its own Java implementation, Visual J++, which would eventually lead to a lengthy legal dispute with Sun Microsystems. The controversy centered on Microsoft’s inclusion of nonstandard Windows APIs, which ultimately led to the removal of Visual J++ from the Visual Studio suite. This could…

Gradle 7.0, the latest update to the widely-used build automation tool, brings significant performance improvements, especially for those involved in Android development and other projects. A major enhancement in this version is the introduction of faster incremental builds, which promise to streamline development workflows and boost productivity. This update builds upon previous incremental build features but takes them a step further by ensuring quicker and more efficient builds, saving developers valuable time. One of the standout features in Gradle 7.0 is the default activation of file system watching. This feature, which was initially available as an opt-in in Gradle 6.5…

Instagram has made its performance-focused fork of Python, Cinder, publicly available as part of Facebook’s Incubator project on GitHub. Based on CPython 3.8, Cinder is designed to improve Python’s performance, with the goal of creating a faster, unified version of CPython. By open-sourcing the project, Instagram hopes to spark discussions about integrating some of its performance improvements into CPython, thus avoiding the need for redundant work on optimizing Python’s execution. Cinder is packed with several performance optimizations that aim to boost execution speed. These include bytecode inline caching, which dynamically replaces generic opcodes with specialized versions; eager evaluation of coroutines,…

The Pyston project, which offers an alternative Python runtime using just-in-time (JIT) compilation and various optimization techniques, has released its 2.2 version this week. One of the most exciting changes in this release is that the entire source code is now available as an open-source project, licensed under Python’s original terms. This move makes Pyston’s faster Python implementation more accessible to developers looking to improve performance without abandoning the Python ecosystem. The primary objectives of Pyston are twofold: first, to create a drop-in replacement for the standard Python runtime that speeds up existing Python applications without requiring significant changes; and…

Blazor, developed by Microsoft, is an open-source, cross-platform framework that enables developers to build modern web applications using .NET and .NET Core. It leverages a flexible component model to create dynamic, interactive single-page applications (SPAs) that run smoothly across various platforms. Blazor provides developers with a powerful toolset to develop rich web UIs, offering an alternative to traditional JavaScript frameworks. One of Blazor’s standout features is its ability to build interactive web applications using C# instead of JavaScript. This approach allows developers to use C# for both client-side and server-side code, making it an ideal choice for teams familiar with…

The internet stands as one of the most transformative innovations of the modern age, offering unprecedented access to information, entertainment, services, and human connection. For billions of people worldwide, the web has become a lifeline, enabling communication and access to resources that were once unimaginable. However, the internet’s impact is not universally experienced. For people with visual or physical impairments, navigating the web can be a daily challenge. Many depend on assistive technologies such as screen readers, voice commands, and other tools to interact with web content. Unfortunately, these technologies often face barriers when web developers don’t design sites with…

JetBrains has introduced the first technology preview of Jetpack Compose for the Web, bringing Google’s popular Kotlin toolkit for building reactive user interfaces to web development. This new extension expands Jetpack Compose’s reach, which was initially designed for Android and desktop applications, to now include web-based projects, giving developers more flexibility in creating unified UIs across multiple platforms. Launched on May 3, Jetpack Compose for Web builds on Kotlin Multiplatform, a framework that enables developers to write platform-agnostic code. This allows the sharing of core functionality, such as business logic, across Android, desktop, and web platforms. Developers can now utilize…

Vercel’s Next.js framework has taken a significant leap forward with its latest release, leveraging Webpack 5 to enhance performance and streamline development workflows. The update, announced on April 28, focuses on accelerating build times and improving application refresh capabilities, making it easier for developers to deliver high-performance React applications. With the introduction of Webpack 5, Next.js 10.2 enables improved disk caching, allowing the compiler to retain progress from previous builds. This optimization ensures that only modified files are recompiled, resulting in build time improvements of up to 63% for subsequent runs. By default, applications without custom Webpack configurations in their…

React continues to dominate as the most widely used JavaScript library for building user interfaces. As applications grow in complexity, optimizing React’s performance becomes essential to delivering a seamless user experience. This article explores key strategies to maximize React performance, focusing on techniques like leveraging functional components, utilizing the Suspense feature, and applying lifecycle methods effectively. At the core of React’s performance lies its virtual DOM, an in-memory representation of the UI that tracks changes and determines the minimal updates needed for the actual DOM. Direct manipulation of the DOM is computationally expensive, so React aims to minimize these updates.…
