Magic Links: Convenient or Catastrophic?

2025-01-07

This article critiques website designs that rely solely on magic email links for login. While secure, the author argues this method is inconvenient for multi-device users, hindering direct login on gaming PCs or work laptops and being susceptible to email delays. It also forces users to access personal emails on work devices, posing security risks. The author suggests offering more flexible login options like passwords or passkeys to improve user experience.

Zig's Comptime: Bonkers Good

2025-01-07

This article dives deep into Zig's compile-time metaprogramming (comptime) capabilities. Initially finding comptime challenging, the author ultimately marvels at its power. Six different perspectives on comptime are presented, including ignoring it, viewing it as generics, standard code run at compile time, partial evaluation, compile-time evaluation with runtime code emission, and textual code generation. Through examples, the author demonstrates how comptime improves code efficiency, simplifies reading and debugging, and enables advanced features like code generation. Zig's comptime allows for extensive computation and code generation at compile time, boosting performance and simplifying code writing.

LLMs and the Limits of Automated Code Optimization

2025-01-07

David Andersen experimented with using Large Language Models (LLMs) to optimize code that finds the difference between the smallest and largest numbers whose digits sum to 30 in a list of a million random integers. Initial Python and Rust code ran slowly. While the LLM improved parts, such as the digit summing function, it missed a crucial optimization: checking if a number is relevant *before* the expensive digit sum calculation. Manual intervention, involving a faster random number generator, parallelization, and preprocessing, sped up the Rust code by a factor of 55. This highlights LLMs' limitations in code optimization, particularly for complex problems demanding deep algorithmic understanding and parallelization strategies. Human ingenuity remains crucial.

Triptych: Three Proposals to Make Hypertext Hyper Again

2025-01-06

Alexander Petros and Carson Gross propose Triptych, three small proposals designed to make HTML far more expressive in how it handles network requests. The proposals add PUT, PATCH, and DELETE support to HTML forms, enable buttons to make requests without forms, and allow for partial page replacement with the response. Triptych aims to bring the best of libraries like htmx to native HTML, enhancing its REST capabilities and simplifying the declaration of page behavior for HTTP requests. This results in cleaner code and easier implementation of both full-page navigation and partial page updates.

Getting LLMs to Generate Funny Memes: Surprisingly Hard

2025-01-06

A University of Waterloo intern attempted to build an app using LLMs and the Greptile API to generate memes that roast GitHub repositories. The process proved unexpectedly challenging. Directly prompting the LLM for roasts yielded generic results. The solution involved separating the task into code analysis (using Greptile to pinpoint specific issues) and roast generation (using the LLM to create targeted humor). Image generation proved difficult due to limitations in handling text, leading to the use of pre-built meme templates and node-canvas for text insertion. Despite the hurdles, the project culminated in reporoast.com, a website capable of generating custom code-roasting memes.

Spline Distance Fields: A Novel Terrain Generation Technique

2025-01-06

To overcome limitations in the Tangerine game engine, the author developed a CPU ray tracer called Star Machine and a racing game prototype, Rainy Road. Rainy Road requires an efficient and compact terrain rendering system capable of handling roads and other terrain features defined by splines. The author introduces a novel terrain generation technique using spline distance fields. This technique utilizes splines to generate terrain surfaces by calculating the distance of a point to the nearest spline and its normal vector to determine elevation. This avoids the limitations of traditional heightmaps and supports procedural object placement. The technique is under active experimentation and research, with exploration of improved interpolation strategies and the use of sparse point clouds.

Evolving a Structural Code Editor: From AST Manipulation to Intuitive UI

2025-01-06

This post details the multi-year evolution of a structural code editor. The initial version directly manipulated the Abstract Syntax Tree (AST), proving cumbersome. Subsequent iterations simplified the AST and explored a text-cursor-based approach, but both fell short. The final version balances AST and text editing, employing techniques like Editable types, Projections, and Frames. A visual, icon-based UI was added, supporting keyboard, mouse, touch, and remote control, significantly enhancing user experience. Built with Gleam and Lustre, this project showcases the ongoing exploration and refinement of structural code editor design.

The Magic Function: Crafting Elegant Abstractions in Rust

2025-01-06

This excerpt from "The Secrets of Rust: Tools" by John Arundel demonstrates elegant abstraction design in Rust using a simple line-counting command-line tool. The 'magic function' approach is employed: first imagining an ideal function, then designing its API based on how it's called, resulting in a clean, reusable library. A unit test ensures correctness, highlighting the importance of API design prioritizing user needs over implementation details.
