HTTP Feeds: Asynchronous Event Streaming with Plain HTTP

2025-04-26

HTTP Feeds is a minimal specification for asynchronous event streaming and data replication using plain HTTP APIs. It defines a simple HTTP GET endpoint that returns a chronologically ordered sequence of CloudEvents in batched responses. Using the `lastEventId` query parameter, clients can poll infinitely for real-time updates, offering a message broker alternative (like Kafka or RabbitMQ). The spec also covers long polling for lower latency, data compaction and deletion for efficiency, and handling of event IDs for robust event processing.

The Curious Origin of Rubber Duck Debugging: A Pixar and Xerox PARC Tale

2025-04-26

The well-known programmer debugging technique, "rubber duck debugging," has a surprisingly hazy origin story. This article traces the technique's source, from the author's initial vague recollection of Bell Labs or Xerox PARC, to its confirmed widespread use within a Pixar team. The story involves programmers explaining problems to a 'rubber duck' (actually a colleague), often solving the problem during the explanation. This isn't simply asking for help; it's using the act of explaining to clarify one's own thinking. While Xerox PARC is a likely birthplace, the exact origin remains a mystery, awaiting further investigation.

Reviving DOS: A USB-Bootable Writing Machine for the 21st Century

2025-04-26

The sheer size and complexity of modern operating systems, even open-source ones, often evokes nostalgia for the days of DOS. A simple, lightweight OS, DOS could boot from three files and configuration was a matter of editing a couple of text files. Now, a community project offers a USB-bootable DOS experience, pre-loaded with classic writing applications like WordPerfect and Arnor Protext. This provides a distraction-free writing environment for those seeking to disconnect from the internet. While limited in functionality, it offers a surprisingly efficient and focused writing experience, harkening back to a simpler time.

Type Less in Your Terminal: Introducing Empty Enter Expander

2025-04-26

Empty Enter Expander is a zsh tool designed to boost terminal efficiency. It lets you execute pre-defined commands with a few keystrokes. Commands are stored in a module directory; directories and filenames must start with lowercase letters, serving as shortcuts. For example, after pressing Enter, 'g, l, Enter' executes a pre-defined git log command. Users can customize commands and shortcuts by placing scripts in the appropriate subdirectories within the module directory. Configuration involves modifying the .zprofile file to set the module path and source the zsh function.

Goodbye Slow Configuration: Parallelizing Build Configuration with Makefiles

2025-04-26

Author Tavian Barnes complains about the inefficiency of existing build systems (Autoconf, CMake, Meson, etc.) in the configuration phase, which takes far longer than the build phase. He proposes a parallelized solution based on Makefiles, significantly improving efficiency by breaking down the configuration process into multiple concurrently executable tasks. The core idea is to leverage make's parallel capabilities to parallelize the originally sequential compiler test tasks, ultimately reducing configuration time from 38 seconds to 0.4 seconds. The article details the implementation, including helper scripts, Makefile writing techniques, and parallelization strategies. This article is valuable for developers seeking faster build speeds.

Functional Logo Maker from a Single Prompt: LLM Potential and Limitations

2025-04-25

The author generated a fully functional logo maker, including export options, from a single prompt in Aider. Code snippets demonstrate the LLM's ability to generate font links, dependencies, and inline CSS styles, even including the latest SHA hash of a linked CDN library. However, expanding the code using Sonnet 3.7 significantly increased project complexity, resulting in uncompilable code. The author explores the differences in code generation and expansion capabilities between different LLMs (like Claude and GPT-4o), and the impact of context window size, output limits, and other factors on LLM applications. The limitations of context windows and output sizes in LLMs are highlighted as key challenges.

Differential Code Coverage for Debugging: A Powerful Technique

2025-04-25

This article introduces a powerful debugging technique: differential code coverage analysis. By comparing the code coverage of passing and failing tests, you can quickly pinpoint buggy code. The author uses Go's `math/big` library as an example, demonstrating how to use `go test` and `go tool cover` to generate coverage reports and `diff` to compare the differences. This efficiently identifies the code snippet causing the test failure, significantly reducing debugging time compared to traditional methods. The technique is illustrated by finding a bug in a few lines of code out of over 15,000.

Substack's Mysterious 'Network Error': A WAF vs. Technical Writing Showdown

2025-04-25

While writing a technical post about DNS resolution on Substack, the author encountered a 'Network Error' whenever they typed certain Linux system file paths (e.g., /etc/h*sts). Investigation revealed that Substack's Web Application Firewall (WAF) was triggering its defenses against path traversal or command injection attacks. This highlights a conflict between security and usability: the WAF, designed to protect the platform, creates a frustrating obstacle for technical writers needing to discuss these system paths. The author suggests Substack improve its WAF's contextual awareness, provide clearer error messages, and offer workarounds to better balance security and the needs of technical writers.
