Goodbye Playwright, Hello CDP: A New Era in AI Browser Automation

2025-08-20

In the realm of AI browser automation, developers have long relied on adapter libraries like Playwright. However, these libraries' abstraction layers obscure the underlying complexities of browsers, leading to performance bottlenecks and difficult-to-solve edge cases. This article details how a team abandoned Playwright and directly used the Chrome DevTools Protocol (CDP) to build a faster and more reliable AI browser automation system. They developed a new Python CDP client library, `cdp-use`, and adopted an event-driven architecture, achieving cross-origin iframe support and significantly improving element extraction and screenshot speeds. This transition, while challenging, ultimately resulted in finer-grained control over the browser and more robust error handling, ushering in a new chapter for AI browser automation.

Rotten Tomatoes Inflation: A Hollywood Secret?

A recent observation of nearly every film on Rotten Tomatoes being labeled "Certified Fresh" sparked suspicion. Data analysis reveals a significant rise in Rotten Tomatoes' average score over the past decade, coinciding with Fandango's acquisition. The author suggests Rotten Tomatoes may be manipulating scores by expanding its reviewer pool to include those giving more favorable reviews. While this might boost box office numbers short-term, it's detrimental to the long-term health of the film industry.

OCaml Editor Gets a Major Boost: Powerful Refactoring Capabilities

During my internship, I added powerful refactoring capabilities to OCaml's Merlin compiler, starting with an "extract toplevel expression" feature. This feature extracts selected expressions into new `let` bindings, supporting constants and expressions (including those using variables), and cleverly handling OCaml's purity issues. Implemented via the Language Server Protocol (LSP) with both code action and custom request interaction methods, the feature is in PRs and nearing merge. This marks a significant step towards an IntelliJ-like editor experience for OCaml, with plans for more refactoring tools in the future.

Rails in 2025: Lago's Case for Sticking with the Familiar

Lago shares its experience building its API with Ruby on Rails. Despite the rise of Python, Go, and JS, they've stuck with Rails, prioritizing its speed in delivering a product. They address scalability concerns, arguing it's an architectural and operational issue, not a framework limitation. With proper design and optimization, Rails handles millions of API requests. The article also acknowledges Rails' weaknesses—performance, concurrency, and 'magic'—and how they use Go and Rust to compensate. Ultimately, they argue that language choice depends on quickly delivering a great product, and Rails fits the bill for their team.

An Infinitely High Stack of Blocks? Impossible!

2025-08-20

This paper explores a counter-intuitive physics problem: the stability of an infinitely extending stack of blocks. By analyzing torque and center of mass, the author demonstrates that finite-height stacks of blocks can remain stable even when their tops extend far beyond the edge of a table—a result that defies intuition. However, when attempting to extrapolate this to an infinitely high stack, the author finds that regardless of the limiting procedure used, the end result is either no stack at all or a stack that doesn't lean. This reveals the subtleties of limit operations when dealing with infinity and the limitations of intuition.
