Action!: A Retro IDE for the Atari 8-bit

2025-09-05

This article revisits Action!, a compiled language for the Atari 8-bit computer. Created by Clinton Parker, Action! was optimized for the 6502 CPU and featured an integrated development environment (IDE) including a monitor, compiler, text editor, and debugger—a rarity for 8-bit systems. While less advanced than C or Pascal, its speed, innovative editor (with features like scrolling and split-screen), and tight integration made it stand out. The author recounts their experience acquiring and using Action!, discussing its limitations and how add-ons like Action! RunTime and Action! ToolKit partially addressed them. Action! primarily saw use in hobbyist and magazine software.

Poisoning LLMs: A Writer's Fight Back Against Data Scraping

2025-09-05

Large Language Models (LLMs) train on vast amounts of data, much of it scraped from the open web without author consent. One author is fighting back by creating intentionally nonsensical mirror articles linked via nofollow tags. The hope is that LLMs, which may ignore nofollow, will ingest this gibberish, degrading their output. While not a perfect solution, the author aims to raise awareness about unauthorized data scraping and the ethical implications for content creators.

Type-Safe Error Handling in Swift 6: A Layered Approach

2025-09-05

Swift 6 introduces typed throws, making error handling more type-safe. This post details a user-friendly layered error model using a custom `SystemError` protocol. This protocol includes properties like `logMessage`, `userFriendlyMessage`, and `underlyingErrors`, and provides recursive functions for looking up error types and generating error stacks. The article demonstrates defining custom error objects using structs and enums, handling Foundation errors, and decoding errors. Examples showcase leveraging typed throws and custom error handling to improve the reliability of Swift projects.

What if OpenDocument Used SQLite?

2025-09-05

This article explores a thought experiment: what if the OpenDocument file format, specifically ODP (OpenDocument Presentation), were built around SQLite? The author argues this would yield significant advantages, including smaller file sizes, faster file saving and startup times, reduced memory usage, built-in versioning, and an improved user experience. The limitations of the current ZIP-based approach are detailed, such as difficulties with incremental updates, slow startup, high memory consumption, crash recovery issues, and limited content accessibility. The author proposes replacing ZIP with SQLite and further suggests splitting content into smaller units within database tables for incremental updates and faster startup. Version control via SQLite is also discussed, allowing for the retention of historical versions and simplifying crash recovery. In essence, the article posits that using SQLite as an application file format can dramatically enhance user experience and performance for applications like OpenOffice.

Hypr MCP Gateway: Simplifying OAuth2 Authentication for Your MCP Servers

2025-09-05

The Hypr MCP team built an MCP Server Gateway, a reverse proxy that simplifies adding OAuth2 authentication to LLM-based workflows. This gateway addresses shortcomings in existing Identity Provider (IdP) software's support for the MCP specification's authorization framework, such as lack of support for Dynamic Client Registration (DCR) and Authorization Server Metadata (ASM). The article details the gateway's implementation, including using Dex as an IdP, handling CORS, and building OAuth2 middleware. It also discusses challenges encountered, like inconsistencies in client handling of dynamic client registration and error responses. The Hypr MCP Gateway offers an easy-to-use, robust solution for securely connecting internal applications to LLM workflows. Check out their open-sourced project on Github.

Fil-C's FUGC: A Parallel, Concurrent, and Accurate Garbage Collector

2025-09-05

Fil-C employs FUGC (Fil's Unbelievable Garbage Collector), a parallel concurrent on-the-fly grey-stack Dijkstra accurate non-moving garbage collector. FUGC boasts multi-threaded concurrent marking and sweeping, avoiding stop-the-world pauses through 'soft handshakes' for non-blocking interaction with mutator threads. Its grey-stack approach eliminates load barriers, requiring only a simple store barrier, while Dijkstra barriers ensure accurate marking. FUGC is non-moving, simplifying concurrent implementation and supporting C, Java, and JavaScript-style memory management including finalizers, weak references, and weak maps, drastically improving Fil-C's memory management efficiency and safety.

Experimenting with and Abandoning a Terminal UI Library

2025-09-04

While developing the game Kartoffels, the author attempted to create a high-performance terminal UI library, Kruci, to replace the existing Ratatui library. Kruci uses a declarative UI design and attempts to improve performance by avoiding pixel-by-pixel diffing calculations. However, Kruci encountered many challenges in handling events, state management, and Z-stacking. Ultimately, the author decided to abandon the project, concluding that optimizing Ratatui or focusing on game development would be more efficient.

Efficient Font Caching with Service Workers

2025-09-04

This code snippet demonstrates how a service worker efficiently caches font resources. It uses `CacheStorage` to cache fonts and includes a versioning mechanism to prevent stale caches from interfering. When a font is requested, the service worker first checks the cache; if a hit occurs, it returns the font directly; otherwise, it fetches the font from the network and adds it to the cache, handling network request errors along the way. The code cleverly uses the `clone()` method to prevent resource consumption issues.

Thunk: Enabling Your Rust Programs to Run on Ancient Windows

2025-09-04

Thunk is a Rust tool that leverages VC-LTL5 and YY-Thunks libraries to enable your Rust programs to run on older Windows systems, even Windows XP. It achieves compatibility by adding VC-LTL to the library search path and using YY-Thunks to compensate for missing APIs in older systems. Thunk offers both command-line tool and library usage, simplifying the process of building programs and shared libraries compatible with older Windows versions. Note: Thunk doesn't guarantee perfect compatibility on older systems; use at your own risk.

Breaking Math.random(): An Improved Algorithm for Inverting Xorshift128+

2025-09-04

The recent vulnerability CVE-2025-7783 exploits an edge case in the Node.js ecosystem, affecting applications using axios or the deprecated request library. The attack requires five consecutive outputs of JavaScript's Math.random(), allowing prediction of future outputs using the z3 solver. This blog post presents a more efficient approach. The author demonstrates a 226-operation algorithm to invert the Xorshift128+ algorithm used by Math.random(), requiring only two full 64-bit outputs. By analyzing Xorshift128+, knowing only the least significant 26 bits of R1 allows determining the remaining bits of L1 and R2. The post also discusses adapting this to the full Math.random() function, highlighting challenges due to bit truncation and proposing a solution using three outputs. Finally, the author shares their experience using ChatGPT for research, noting its potential while acknowledging current limitations.

Reliable Data Sending with JavaScript's Beacon API: Ditching Unreliable `beforeunload`

2025-09-04

Sending data reliably to servers when a user leaves a website has always been a challenge. Traditional methods using the `beforeunload` event with `fetch` or `XMLHttpRequest` are unreliable, as browsers may cancel requests for a better user experience. JavaScript's Beacon API offers a 'fire-and-forget' solution; the browser doesn't wait for a response, ensuring data is sent reliably. While the Beacon API limits data size and only supports POST requests, it's perfect for sending small, critical data like analytics or page leave events. It's also great for any scenario requiring reliable asynchronous data sending, such as real-time data synchronization.

C Compiler in 500 Lines of Python: A Single-Pass Approach

2025-09-04

The author undertook the challenge of writing a C compiler in just 500 lines of Python, targeting WebAssembly. To achieve this, a single-pass compilation strategy was employed, foregoing an Abstract Syntax Tree (AST) and generating code directly during parsing. This resulted in a concise compiler, but at the cost of several features, including floating-point numbers and structs. The resulting compiler successfully compiles and runs simple C programs, demonstrating the feasibility of a single-pass approach.
