The Rust 2021 edition, the upcoming third iteration of the Rust programming language, is set for release in October and promises to refine the developer experience by addressing several subtle yet impactful changes. These improvements are designed to make working with Rust feel more intuitive and seamless, enhancing the overall experience for developers using the language in practice. One of the key updates in Rust 2021 involves a new prelude to the standard library. The prelude, which automatically imports modules in every file, will undergo adjustments to fix a longstanding issue where adding a trait could unintentionally break code. This…

Scala 3, the latest version of the versatile programming language that supports both object-oriented and functional paradigms, has officially been released for production. This new version brings a comprehensive redesign of the language, promising significant improvements in usability and performance. With enhanced features such as a revamped type system and cleaner syntax, Scala 3 aims to streamline the development process while maintaining its robustness for high-performance system development. Released on May 14, Scala 3 follows a release candidate phase that began earlier in February. One of the standout features of this release is the introduction of a “quiet” syntax for…

At the Python Language Summit during PyCon 2021, Guido van Rossum, the creator of the Python language, revealed ambitious plans aimed at significantly improving Python’s performance. The proposal outlines near-term and long-term goals that could see Python running anywhere from two to five times faster, and potentially even more. This announcement has sparked excitement within the Python community, as developers look forward to more efficient ways to execute Python code. While there are already several ways to increase Python’s speed, such as using alternative runtimes like PyPy or wrapping modules in C/C++, most of these methods do not focus on…

Deno 1.10, the latest release of the security-oriented runtime for JavaScript and TypeScript, brings several significant enhancements, including an overhaul to the built-in test runner and the addition of the Web Storage API. Released on May 11, this update introduces new features aimed at improving both performance and developer experience. One of the most notable changes in Deno 1.10 is the update to the deno test command. In this version, test modules are executed in isolation, each using a new instance of the runtime. This is a departure from previous versions, where tests were run sequentially within a single runtime…

JavaScript continues to enjoy a period of rapid growth and innovation. One of the standout players in this landscape is the Svelte framework, which has quickly gained attention for its unique approach to building web applications. In this article, we’ll explore how to get started with Svelte, offering a look at some of the basic steps involved in setting up a project and using key UI elements. Svelte differentiates itself from the likes of React, Angular, and Vue by shifting much of the work to the server side. Rather than relying on a browser-based runtime to interpret and manage application…

Despite its widespread use by millions of developers, the Babel JavaScript compiler project, an essential tool for modern web development, is facing a financial crisis. The open-source project, which plays a critical role in transforming the latest JavaScript into compatible code for older environments, has long depended on donations and volunteer contributions. However, as the project’s needs have grown, so too has the financial burden. In a recent update, the Babel core team shared that their current funding model is insufficient, prompting them to seek additional financial support from corporate sponsors. Since 2018, the Babel team has been conducting a…

Choosing the right web framework for your application front-end can be a challenging decision, especially with so many options available today. From popular JavaScript libraries like React and Vue to web component frameworks like Salesforce’s Lightning and Google’s Polymer, the variety of choices can be overwhelming. These frameworks provide powerful templating models that allow developers to create and customize reusable components, leveraging the flexibility of custom elements and the isolation offered by the JavaScript shadow DOM. Despite the advantages, the adoption of web components has been slower compared to other HTML5 technologies. Several factors have contributed to this, such as…

ASP.NET Core 5 MVC is a powerful and lightweight framework designed for building dynamic, scalable web applications. Built on the ASP.NET Core 5 runtime, it supports a range of features that allow developers to manage both request and response headers. These headers are key-value pairs sent between the server and the client, conveying essential information such as content type, authorization credentials, and custom metadata. In this article, we will explore how to read request headers in an ASP.NET Core 5 MVC application. Specifically, we will make use of the Request.Headers collection, which is part of the Microsoft.AspNetCore.Http.Headers namespace. This collection…

Kotlin 1.5.0, the latest stable release of JetBrains’ statically typed programming language, brings significant updates aimed at improving the language’s interoperability with Java and enhancing its feature set. A standout addition is the stable support for JVM records, which allows Kotlin to work seamlessly with Java’s latest record feature. JVM records provide a more concise way to define classes that are intended solely for holding immutable data, enabling developers to create simple data containers without boilerplate code. This new functionality aligns Kotlin with modern Java standards, making it easier for developers to work with both languages in the same project.…

Instagram has open-sourced Cinder, a high-performance fork of CPython 3.8, now available as a Facebook Incubator project on GitHub. The primary goal behind releasing Cinder is to create a faster and more unified version of CPython, addressing some of the performance bottlenecks inherent in the reference implementation of Python. By sharing Cinder as an open-source project, Instagram hopes to foster discussions about incorporating some of its performance improvements into CPython itself, while reducing redundancy in ongoing performance efforts for Python. Cinder incorporates several performance-enhancing features to boost Python’s execution speed. These include bytecode inline caching, which dynamically optimizes frequently used…
