Emacs Lisp (Elisp) is a small, elegant Lisp dialect that powers Emacs. Even if you’re not writing full Emacs packages, understanding a few essential constructs can help you automate tasks, customize your editor, and write smarter configuration code.
In this article, we’ll explore some of the most useful, everyday Elisp building blocks that every Emacs user should know — with small, practical examples you can immediately paste into your config.
Keeping your Emacs packages up to date is essential if you want the latest features, performance improvements, and security fixes. But manual updates can quickly become a chore — especially if you use Emacs as your main development environment and rely on dozens of packages.
Learn how to reduce load times, improve scalability, and cache smartly using Symfony’s built-in HTTP caching tools, Edge Side Includes (ESI), and the Varnish reverse proxy.
Why HTTP caching matters
HTTP caching sits between your users and your backend, serving popular pages directly from memory without hitting PHP. With proper caching headers, you can reduce server load and deliver content in milliseconds instead of seconds.
Symfony is built around a simple but powerful idea: everything is a bundle. A bundle is a self-contained package of code — controllers, entities, services, and templates — that can be reused across multiple projects.
In this guide, we’ll walk through how bundles work, how to create your own, and how they fit into a modern Symfony 7 application.
As artificial intelligence produces more and more online content, it’s becoming harder to tell what’s written by humans and what’s generated by machines. It’s convenient and efficient — but it also comes with a serious risk: the gradual loss of quality, depth, and diversity across the web.
When starting a new PHP project, Composer is the foundation of modern PHP development. It automates dependency management, handles autoloading, and ensures your codebase remains consistent across environments.
But with more than 350,000 packages on Packagist, it can be overwhelming to find the right tools. Below is a curated list of the 10 most useful Composer packages every developer should know in 2025.
If you come to Symfony from Laravel, Drupal, or Node.js, one of the first concepts you meet is the bundle. It looks a lot like a plugin or module — until you start working with it.
Bundles embody a design philosophy that’s distinctively Symfony: composition over inheritance, configuration over convention, and strict separation of concerns. Understanding this idea is key to grasping why Symfony applications remain maintainable at scale.
The PHP ecosystem has evolved dramatically over the last decade. Frameworks like Laravel, Slim, and CodeIgniter have matured, while newcomers such as Spiral and Hyperf are introducing async paradigms and reactive programming.
Yet, amidst all this change, Symfony continues to be the gold standard for modularity, stability, and architectural discipline. It’s not the most lightweight or trendy framework, but it remains the one that other frameworks borrow from — quite literally, in Laravel’s case.
Artificial Intelligence has become an integral part of the modern developer's workflow — from code suggestions to natural language search and data enrichment. But most of these tools come at a cost: constant internet connections, cloud-based APIs, and corporate monitoring of every token you generate.
Many developers (myself included) have started to ask: what if we could bring AI back under our own control? Luckily, in 2025, open source models and local inference engines are finally good enough to make that vision real.
