Tailwind CSS v4 brings a new compiler, CSS-first configuration, OKLCH colors and improved variants. This cheatsheet covers all key classes and new concepts, as a fast reference for everyday development.

Certificate pinning protects mobile apps and API clients against man-in-the-middle attacks where an attacker presents a technically valid certificate, signed by a trusted certificate authority, that nonetheless does not belong to the real backend. We explain why public key pinning beats classic certificate pinning, how backup pins work, and how to avoid accidentally locking your own users out.

Namespaces isolate what a process can see, seccomp limits what a process is allowed to do at all. Anyone thinking about container hardening purely in terms of capabilities and namespaces overlooks one of the most effective defenses against kernel exploits: deliberately blocking system calls an application simply never needs during normal operation.

Overloads let a single function expose several callable signatures while only one implementation exists behind the scenes. Used correctly they produce far more precise return types than a single signature built from union types, but they also come with their own pitfalls, from resolution order to unreachable signatures.

Every unpatched Magento store is an open invitation the moment a vulnerability becomes public. This article covers Adobe's release cadence, the real time window between CVE disclosure and active exploitation, a Composer-based patch workflow with staging tests, and the most common excuses for not patching along with why they fail in practice.

A bridge network ends at the boundary of a Docker host. As soon as a setup spans multiple physical or virtual machines, an overlay network takes over communication between containers, no matter which host they actually run on, encrypted and with built-in load balancing.

A form gets submitted right when the connection drops. Instead of showing an error and discarding the input, the Background Sync API remembers the action and reliably replays it once the network returns, even if the tab has long been closed.

Well over six years after Magento 1 reached end of life, shops still run on the old platform, without security updates and with growing risk. A clean Magento 1 to Magento 2 migration requires far more than the Data Migration Tool: EAV mapping pitfalls, a complete theme rebuild, URL redirects and converting password hashes decide whether the switch goes smoothly or ends in data loss.

Anyone who first sees a console.log inside a useEffect suddenly appear twice in the development build almost always assumes it is a bug. In reality, the double execution under Strict Mode in React 18 and 19 is deliberately built in to expose exactly the effects that lack correct cleanup and would otherwise turn into hard-to-find bugs in production later.

PhpStorm on a Magento 2 project with hundreds of thousands of vendor files can feel like a sluggish tool. The reason is almost always the same: too many files in the index, too little heap memory, too many active plugins. With systematic diagnosis the problem can be fixed within an hour.
