The content discusses the workings of Anthropic's API, specifically how it handles requests involving model interactions. Users choose a model, set token limits, and send messages, with an option to enable "extended thinking" by adding a parameter. The API utilizes unique XML tags, referred to as ANTML (possibly "ANThropic Markup Language"), to signify when the model is engaged in thinking. These tags distinguish special processing from regular prompt tags. Anthropic regularly shares simplified versions of their system prompts,

Quibbler is a background tool designed to critique and improve the performance of your coding agent by automatically observing its actions, correcting errors, and enforcing learned rules based on your coding patterns. It supports integration through two modes, requiring specific setup instructions depending on the type of coding agent you are using. To implement Quibbler, you will need to configure your agent's MCP server, create or update a documentation file for agent instructions, and start a Quibbler hook server. It learns from interactions with

TikTok significantly improved the performance of its critical Go APIs by rewriting them in Rust, achieving 2x performance enhancement and $300K annual cost savings. The changes were necessary due to the APIs facing high traffic (100K queries per second), which led to CPU bottlenecks caused by intensive serialization/deserialization, garbage collection pauses in Go, and inefficient memory allocation. The team opted to rewrite only the CPU-bound APIs in Rust, leaving the remaining APIs in Go. This selective migration resulted in

The content discusses the concept of virtual lists, which efficiently render large lists of items by only displaying visible elements and removing those that are out of view, thereby saving memory. The author employs `react-window` in the Superintendent.app and `svelte-virtual-list` for Backdoor, their tool for querying and editing Postgres data. However, both libraries face a limitation in Google Chrome, where no div can exceed a height of 16,777,200 pixels. This height presents issues as

The content discusses a demo presented at Zigtoberfest 2025, showcasing the new async I/O features introduced in Zig's std.Io patchset, set to be released in Zig 0.16.0 in a few months. The presentation begins with a basic "Hello, World!" example in Zig, emphasizing the significance of proper setup for I/O operations. A standard setup involves initializing an Io implementation based on threads and passing it throughout the application, similar to how allocators are used

The cochlea processes sound by utilizing the vibrations received from the tympanic membrane (eardrum) and amplified by the middle ear bones. These vibrations travel through fluid in the cochlea and reach the basilar membrane, which separates frequencies: the stiff base resonates with high frequencies, while the flexible apex resonates with lower ones, creating a logarithmic frequency gradient. Hair cells on the basilar membrane respond to these vibrations and convert mechanical motion into electrical signals through a process involving ion channels. The auditory system

Apple's Vision team introduced their innovative telepresence feature, called Personas, within the Vision Pro VR headset. This feature allows multiple users, all wearing Vision Pros, to communicate in real time as virtual replicas of themselves through 3D photo scans. While various companies have explored telepresence using avatars, Apple's Personas stands out as the most advanced in the VR and AR space. During a recent meeting in the headset, the author experienced the immersive technology firsthand with Apple's Jeff Norris and Steve Sinclair, noting that

The author announces the release of llm-docs-builder, an open-source library designed to optimize Markdown documentation for Large Language Models (LLMs) by reducing unnecessary noise. The tool can strip away 85-95% of non-essential content, such as HTML formatting, allowing AI systems like Claude and ChatGPT to focus on the relevant documentation. This transformation significantly reduces costs associated with Retrieval-Augmented Generation (RAG) by minimizing the token usage in typical HTML documents. Metrics from the Karafka framework

Last week, during a public conversation, the author realized they failed to practice what they preach about open discussions when they privately messaged a colleague for clarity on who should handle a request. The author promotes documented decisions and public conversations to keep the team informed but recognized their own inconsistency. They reflected on recurring patterns of private communication across various companies, including: 1. **Pre-Flight Check**: Individuals seeking validation or approval in private before sharing publicly. 2. **The Great Migration**: Discussions
