Securing web applications has always been a challenging endeavor, especially with the growing demand for robust and scalable APIs. Spring Security is a powerful Java-based framework designed to address this need, but its extensive feature set can make it intimidating for newcomers. This guide simplifies the process of securing a REST API with Spring Security, using JSON Web Tokens (JWTs) for authentication and authorization. JWT has gained widespread adoption as an authentication mechanism due to its simplicity and compact design. Unlike traditional session-based authentication, JWT allows for stateless communication between the client and server, making it particularly well-suited for RESTful…

In the latest update to Visual Studio Code, Microsoft has introduced several enhancements aimed at improving the development experience, with a particular focus on automatic language detection. As of version 1.60, language detection is now enabled by default, streamlining the process of setting the appropriate language mode for untitled files. This machine learning-powered feature, which was initially previewed in version 1.59, is designed to analyze the content of a file and automatically assign the correct language mode, even for files that lack file extensions. This shift toward automatic detection ensures a smoother, more intuitive workflow for developers. Visual Studio Code…

Anaconda, a leading platform provider in the data science ecosystem, has taken a significant step toward advancing Python performance by hiring the lead developers of Pyston, an alternative Python runtime. With Kevin Modzelewski and Marius Wachtler on board, Anaconda aims to foster an open-source community around Pyston, ensuring its sustainability and growth. This move aligns with the overarching goal of improving Python’s performance across a broad spectrum of applications, making it a valuable asset for developers and data scientists alike. Pyston, designed to be a high-performance fork of the standard CPython interpreter, already boasts impressive results, running Python code 20%…

GitHub recently introduced the Github.dev service, making it easier than ever to edit code directly in your browser. If you’re exploring a repository and spot something that needs tweaking, you can launch the editor by simply pressing the “.” key or altering the URL to replace .com with .dev. This action opens a browser-based version of Visual Studio Code’s core editor, complete with features to make quick edits and commit changes back to the repository without needing to leave your browser. This service is particularly useful when you don’t have access to your primary development setup. Whether you’re away from…

Deno 1.13, released on August 10, marks a significant milestone for the JavaScript and TypeScript runtime with the stabilization of its native HTTP server API. This update enhances Deno’s ability to handle HTTP traffic seamlessly, including support for both HTTP/1.1 and HTTP/2 protocols. By exposing the hyper web server as a JavaScript API, Deno simplifies the process of serving diverse HTTP traffic out of the box. Developers using the older std/http module are encouraged to migrate to the new HTTP server API, as the former is slated for removal in a future release. Initially introduced in Deno 1.9, the HTTP…

JetBrains has released Kotlin 1.5.30, introducing a range of experimental features and enhancements to the standard library. These experimental updates, including sealed when statements and the ability to instantiate annotation classes, hint at what developers can expect in the upcoming Kotlin 1.6.0 release. With a focus on making code safer and more expressive, these features are designed to streamline development while addressing key gaps in the language’s capabilities. Sealed when statements are a significant addition, enabling the compiler to issue warnings if a when statement is not exhaustive. This helps developers catch potential errors and ensures all possible cases are…

SvelteKit is poised to be a significant evolution in the world of web development, positioned as the successor to Sapper, the full-stack framework for Svelte that enabled server-side prerendering. Much like how Next.js has revolutionized React applications, SvelteKit brings a new level of versatility and ambition to the Svelte ecosystem, making it a strong contender in the space of modern web frameworks. While SvelteKit shares many similarities with Sapper, it introduces several innovative features that make it a more robust solution for developers. Notably, it supports targeting different production environments, including serverless architectures, giving developers more flexibility in deploying their…

Despite the strides made in abstracting and industrializing programming, at its core, software development is still deeply rooted in mathematics. The algorithms, structures, and programming languages we use are built on mathematical principles that provide the foundation for code. These mathematical concepts shape the tools and methods we rely on to craft functional software. Code, by its nature, is complex. It’s a web of functions that interact with each other in intricate ways, executing under various conditions. While we can observe that code works, the real question is whether we can definitively prove it does. This challenge has led to…

JetBrains’ GoLand, a popular cross-platform IDE tailored for Go programmers, is preparing to integrate support for generics, a highly anticipated feature in the Go language. Generics, slated for introduction in Go 1.18, promise to enhance code reusability and simplify program development. JetBrains’ roadmap for GoLand 2021.3, published on August 12, highlights the addition of features such as code inspections, refactorings, and intention actions specifically designed to work seamlessly with generics. Alongside support for generics, the GoLand 2021.3 update includes a new workspace mode aimed at enhancing productivity. This feature will allow developers to implement changes across multiple modules from a…

String interpolation is a powerful feature that allows you to embed expressions directly within string literals. Commonly referred to as variable substitution or expansion, it enables seamless integration of values into strings by replacing placeholders with corresponding values. This approach improves code readability and reduces the need for manual concatenation, making your code cleaner and more maintainable. Many modern programming languages, including Python, PHP, Ruby, and Java, support string interpolation. In C#, this feature was introduced in version 6. Since then, it has become a cornerstone for handling strings dynamically and effectively. This article explores how to utilize string interpolation…
