The content discusses the author's strong dislike for the `core::io::BorrowedBuf` feature in Rust nightly, despite acknowledging that it offers an opportunity to refine its design before stabilization. The article focuses on the inefficiencies in the `slow_copy` function, which unnecessarily zero-initializes a buffer during data copying, preventing the compiler from optimizing it. The author suggests using `MaybeUninit` for uninitialized memory as a partial solution but points out that this method can lead to unsafe and unpredictable

The content discusses a challenging situation faced by an engineering team at Tweede Golf while working with the nRF9160 microcontroller, which features an efficient LTE modem. After successfully creating firmware using Rust and Embassy for a client, the team believed their work was complete. However, six months later, the client reported intermittent issues with the firmware that led to frequent error messages when sending data to a server. The problem was sporadic and sensitive to changes in the code, compiler version, and optimization settings, making

Companies adopting Kubernetes often explore developing custom controllers due to the appeal of declarative configurations. However, the ease of using tools like Kubebuilder can lead to poorly designed controllers being deployed in production, as developers may lack a deep understanding of Kubernetes' API conventions. Mistakes commonly arise from insufficient knowledge about the distinctions between different API fields—such as the roles of status and spec—and the overall design principles governing Kubernetes' built-in APIs. Consequently, organizations may face significant challenges when needing to revise poorly designed

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

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.
