Koa.js: A Next-Gen Node.js Web Framework

2025-01-10

Koa.js, from the creators of Express, is a new web framework for Node.js that aims for a smaller, more expressive, and robust foundation for web applications and APIs. Leveraging async functions, Koa ditches callbacks and significantly improves error handling. It doesn't bundle middleware, offering instead an elegant set of methods for building fast and enjoyable servers. Middleware cascades in a streamlined fashion, and Koa provides a rich context with methods simplifying common HTTP tasks like content negotiation, caching, and redirection.

Visualizing Ruby's Lazy Enumerator: A Simple Trick

2025-01-10

This article uses an interactive demo to explain Ruby's lazy enumerator, `Enumerator::Lazy`. Unlike default eager enumeration, lazy enumeration only computes elements when needed, avoiding unnecessary work, especially beneficial with large datasets or complex data transformation pipelines. The article visually demonstrates the difference using 'vertical' and 'horizontal' analogies and suggests resources for a deeper dive into Ruby's lazy implementation.

Tracing JITs in PyPy: A Pragmatic Choice?

2025-01-10

This post delves into the advantages and disadvantages of tracing JIT compilers, specifically focusing on their implementation within PyPy. Tracing JITs, which generate code by tracing program execution, offer benefits when handling complex languages like Python, effectively slicing through layers of abstraction and reducing overhead. However, they also suffer from performance instability and edge cases. Based on two decades of experience with PyPy, the author provides a nuanced analysis of tracing JITs' suitability, comparing them to method-based JITs. The conclusion suggests that, within PyPy's meta-JIT context and given its resource constraints, tracing remains a relatively pragmatic approach.

Chat-Driven Development: A Superior Approach to LLM Coding

2025-01-10

Shekhar Gulati, after multiple unsuccessful attempts with GitHub Copilot, advocates for 'chat-driven development' using ChatGPT or Claude. He argues this approach offers a cleaner environment for concise requests, better context control, and improved energy management. It also protects the development environment and facilitates iterative error correction through a simple feedback loop, avoiding the clutter of IDE integrations. Gulati prefers using LLMs as thinking tools for design and brainstorming rather than solely as code generators.

Apple's Killed MacBASIC: The Story of a Programming Language Stifled by Microsoft

2025-01-10

In 1984, Apple developed MacBASIC, a BASIC interpreter for the Macintosh that accessed Macintosh Toolbox routines, making it a powerful prototyping tool. However, this promising language was abruptly halted in 1985, with all source code destroyed. Rumor has it that Apple succumbed to pressure from Microsoft, trading a perpetual license to the Macintosh UI and MacBASIC for an extension of their Applesoft BASIC license. This decision angered Apple employees, and MacBASIC was killed, leaving a mark as a regrettable chapter in tech history.

Solving the Ligature Puzzle in Monospace Fonts

2025-01-10

A developer building a graphical code editor encountered a challenge with ligature rendering in monospace fonts. Enabling ligatures introduced an extra glyph, "LIGSPACE", causing incorrect rendering for certain character combinations. Through experimentation, the developer discovered this wasn't a true ligature, but a zero-width placeholder adjusting spacing. The solution involved ignoring glyphs with zero rendering dimensions, effectively resolving the issue. This post shares the findings and insights gained during this debugging journey.

Swift Move Semantics: A Comparison with C++

2025-01-09

This article delves into the similarities and differences between move semantics in Swift and C++. Swift automatically performs move optimizations, which is beneficial for performance but can surprise C++ programmers accustomed to the RAII idiom. Swift's "non-copyable types" are similar to C++'s "move-only types," but Swift's moves are destructive, avoiding potential issues with C++'s "non-destructive moves." The article compares Swift's `consume` with C++'s `std::move`, and explains Swift's shortened variable lifetimes, parameter passing conventions (`consuming`, `borrowing`, `inout`), and the Law of Exclusivity. Finally, it discusses using non-copyable types for RAII, generics, and conditionally copyable types in Swift, and why Swift lacks perfect forwarding.

SQL's treatment of NULL values often defies expectations. This post reveals the surprising behavior of NULLs in unique constraint columns: multiple NULLs can coexist. Through practical examples in SQLite, Postgres, and MySQL, the author demonstrates how NULLs behave differently with the '=' and 'IS' operators, explaining the underlying reasons. Two solutions for ensuring uniqueness are explored: creating a generated column and using a partial index. Using a partial index is recommended as best practice, avoiding table size increases and potential errors.

The iPhone Performance Illusion: A Stark Reality Check for Web Developers

2025-01-09

This article exposes a significant performance gap in mobile web applications. Using data from Rum Archive, the author compares UK iOS and Android users' web page loading speeds, revealing Android users experience 34% slower First Contentful Paint (FCP) and a staggering 66% slower Time To Interactive (TTI). Analyzing the correlation between GeekBench CPU scores and Interaction to Next Paint (INP), the author shows that low-end Android devices exhibit significantly higher INP times than high-end devices, with even older iPhones outperforming the latest top-tier Android phones. The author stresses that the large Android user base shouldn't be ignored; neglecting their experience leads to lost opportunities. The article urges developers to understand user device diversity, use RUM tools to gain insights into real-world conditions, and simulate low-end devices during development and testing to create more inclusive web apps.
