The RFD describes a specific kind of deadlock in asynchronous Rust programming called "futurelock." This occurs when a resource owned by Future A is needed for Future B to continue, but the task managing both Futures is not actively polling Future A. The issue was highlighted by Oxide in a GitHub issue. An example program is provided, showcasing a predictable deadlock scenario. The program involves a background task that holds a lock for 5 seconds, during which two Futures are being awaited. One Future

The release of version 0.7.7 of C3 introduces significant improvements in usability, specifically with changes to the vector ABI, which now handles vectors as arrays in function calls and structs. This eliminates the need for conversion between C structs and SIMD vectors, streamlining the development process. Additionally, alignment for vectors now matches that of structs and arrays, simplifying their usage. New features include a splat operator for initializer default values, implicit subscript dereferencing with the ability to use the .[

This module focuses on browser and network fingerprinting, which are crucial for web automation and detection systems. Fingerprinting combines elements from network protocols, cryptography, and behavioral analysis to identify and track devices and users without traditional identifiers like cookies or IP addresses. Each browser connection reveals various characteristics, such as TCP options order, GPU rendering patterns, and JavaScript execution timings, which collectively form a unique fingerprint for a device or browser. For automation engineers and privacy-conscious users, understanding fingerprinting is vital for creating

The Coder Cafe discusses the Therac-25 accidents, highlighting how design and software failures led to multiple radiation overdoses and fatalities. This machine, which combined low-energy and high-energy radiation therapies for treating tumors, was attractive for hospitals due to reduced maintenance and operational simplicity. However, the shift to a computer-controlled system eliminated critical safety interlocks present in earlier models. An incident occurred when a radiology technologist, by habit, selected X-ray mode and then switched to Electron mode but encountered a

The article discusses the issue of high noise levels in AI code review tools, which typically generate many comments on pull requests (PRs), most of which are unhelpful. It introduces a framework for measuring the quality of AI code reviews based on a signal-to-noise ratio, where useful comments (categorized into three tiers) are compared to the total number of comments. A ratio below 60% indicates a tool that generates more noise than signal. It highlights a study analyzing comments from 22

The author of RailsBilling, a gem designed for easy Stripe subscription integrations in Rails, discusses improvements made in creating subscription plans. Initially, the process involved manually creating standard, pro, and enterprise plans with various intervals, which although effective, had some drawbacks. The author introduced a new approach called the "Friendly Attributes Pattern," which simplifies the creation process by eliminating redundant keys and making the code easier to read and write. This new schema not only models a pricing page more clearly but is also idempotent

The content discusses garbage collection in JavaScript, particularly in the context of long-running Node.js servers. It highlights that while the V8 garbage collector (GC) manages memory automatically, developers should write code that aligns with the GC’s assumptions to avoid performance issues, such as memory leaks. Over time, memory usage can increase subtly, leading to crashes when the system runs out of memory. The V8 engine organizes memory into New Space and Old Space, and understanding this structure is crucial for optimizing server performance

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
