The most popular option to decompress ZIP files from the Rust programming language is a crate simply named zip — At the time of this writing, it has 48 million downloads. It’s fully-featured, supporting various compression methods, encryption, and even supports writing zip files. However, that’s not the crate everyone uses to read ZIP files. Some applications benefit from using asynchronous I/O, e

Tomasz Jakut reflects on the evolution of web design, from the days of table-based layouts and Flash games to the rise of responsive web design (RWD), which often feels like the end of history in web layout. But as 2025 marks the 15th anniversary of Ethan Marcotte’s article, it’s worth asking whether something significant happened after RWD — something so seamless that it went almost unnoticed.

WHAT IT IS Meta’s Automated Compliance Hardening (ACH) tool is a system for mutation-guided, LLM-based test generation. ACH hardens platforms against regressions by generating undetected faults (mutants) in source code that are specific to a given area of concern and using those same mutants to generate tests. When applied to privacy, for example, ACH automates […]

We’ve previously described why we think it’s time to leave the leap second in the past. In today’s rapidly evolving digital landscape, introducing new leap seconds to account for the long-term slowdown of the Earth’s rotation is a risky practice that, frankly, does more harm than good. This is particularly true in the data center […]

The @view-transition at-rule has two descriptions. One is the commonly used navigation descriptor. The second is types, the lesser-known of the two, and one that probably envies how much attention navigation gets. But read on to learn why we need types and how it opens up new possibilities for custom view transitions when navigating between pages.

Refactoring is something developers do all the time—making code easier to understand, maintain, and extend. While IDEs can handle simple refactorings with just a few keystrokes, things get tricky when you need to apply changes across large or distributed codebases, especially those you don’t fully control. That’s where codemods come in. By using Abstract Syntax Trees (AST), codemods allow you to a
