OpenHaystack is a framework developed for tracking personal Bluetooth devices using Apple's Find My network. It enables users to create custom tracking tags that can be attached to various objects or integrated into devices. The application requires a Mac and a Bluetooth-capable device, like a BBC micro:bit, allowing users to track their accessories globally without cellular coverage. Nearby iPhones can discover these accessories and relay their locations to Apple's servers. The project stems from research conducted by the Secure Mobile Networking Lab at TU Darmstadt,

In a personal memoir, Esther Schindler reflects on her experience scanning thousands of family slides, which her late father, an enthusiastic amateur photographer, had amassed. While he took many pictures during family vacations, he never organized or labeled them, leaving behind large, unprocessed collections after his sudden death post-retirement. Following the passing of her mother, Schindler inherited the boxes and embarked on the significant task of preserving the 8,000 to 10,000 slides before they deteriorated further

The question "How long is a second in JavaScript?" leads to a complex exploration of time measurement, rooted in historical and scientific developments. Early civilizations based time on natural phenomena, such as the moon's phases and the sun's movement, establishing units like days and months. Over time, ancient societies, notably the Egyptians and Babylonians, divided the day into 24 hours and subsequently subdivided hours into minutes and seconds, a system still in use today. With the need for more precision in

The blog post discusses methods to drastically reduce Rust compilation times, specifically achieving a reduction from 108 seconds to just 1 second for matmul benchmarks. While not all Rust projects can benefit from these optimizations, the techniques may still provide valuable insights for developers looking to improve compilation efficiency. Key optimizations included swapping element-type generics to minimize LLVM code generation, using a comptime system instead of associated const generics, and setting the LLVM optimization level to zero for debug builds. The motivation for these

The article discusses the common use of 100nF decoupling capacitors in electronics, noting that this practice originated in the 1980s and continues today, despite its outdatedness. Many designers often combine a 100nF capacitor with a larger value (e.g., 1uF) by placing them in parallel. The text emphasizes that understanding the underlying issues that decoupling capacitors address is crucial. In digital electronics, such as microcontrollers, the frequent switching of trans

ScopeDB is a cloud-based database that operates directly on S3, providing benefits such as cloud elasticity and workload isolation. It uses a stateless Rust binary for its servers, eliminating the need for local disk management, data sharding, or complex leader election. This architecture allows ScopeDB to achieve ten times the cost efficiency and performance compared to traditional shared-nothing databases by leveraging S3 for data replication and automatically adjusting server numbers based on workload demands. The text also discusses a scenario involving an observability

The text discusses the dilemma faced by protesters, activists, and journalists regarding the use of smartphones during protests. While smartphones are crucial for organization, communication, and documentation, they also pose risks due to potential surveillance and confiscation by authorities. The safest option is to leave the phone at home, but this limits access to real-time information. An alternative is to use a secondary or "burner" phone, which can help minimize risks since any data not taken to the protest cannot be accessed by authorities.

The author reflects on their experience designing and partially building a library for model validation at a financial institution. The project, initially sparked by personal interest, evolved into a more substantial endeavor with its own team. The blog emphasizes the significance of model validation in finance, particularly in determining the "fair value" of financial instruments, which is crucial for accurate financial reporting. Fair value assessors often rely on market prices for public stocks, but valuing more complex assets, like private equity, can be challenging and requires

The content introduces a two-part series exploring how HTML and CSS render visually in web browsers, focusing exclusively on these technologies without involving JavaScript. It discusses the initial steps in the rendering process, which begins when a server sends an HTML document to the browser. The browser's renderer receives this document, parses the HTML to create a Document Object Model (DOM), and converts raw byte data into recognizable characters. These characters are further processed into tokens, which are structured representations of HTML tags. This tokenization is
