The author reflects on the strengths of the functional programming (FP) tradition, particularly in tools for reasoning about programs, such as static types and algebraic data types. After a decade of writing Haskell, the author warns against confusing program reasoning with system reasoning, emphasizing that these are distinct activities. While many programming communities focus on the program as their primary subject, the FP community may overly rely on its powerful correctness tools, leading to misplaced confidence in system-level properties. The essay specifically addresses the context of

The content introduces "Kaoru Pairs," a new organizational approach for processor transistors that groups them into pairs at the software level. Each pair includes a dedicated readout element, allowing for simultaneous access to all possible states of a transistor group. This innovation reduces the complexity of the fundamental read operation from O(n) to O(1) without requiring any hardware modifications to existing transistors, as the changes are implemented purely through software reorganization.

The article discusses the current state of the Large Hadron Collider (LHC) following its initial triumph with the discovery of the Higgs boson in July 2012. While the Higgs boson confirmed the existing Standard Model of particle physics—a comprehensive framework of known elementary particles—physicists had anticipated new discoveries that would extend this model. However, the LHC has not produced evidence for new physics phenomena or insights into unresolved questions like dark matter, the matter-antimatter imbalance, or

The content discusses the development of a coding agent called Detritus, created in just 250 lines of Ruby code. Scott Werner, the founder of Sublayer, noted that the rapid development of Detritus suggests that creating coding agents will soon be accessible to everyone. Detritus is described as a full-featured coding agent, including a command-line interface with chat history, custom commands, and configuration options. The ease of building this agent is attributed to two main factors: the general availability of

The United States faces a significant challenge regarding its tungsten supply, as it has historically relied on Chinese production. As demand for tungsten is projected to increase due to applications in defense and semiconductors, as well as the potential emergence of nuclear fusion technology, the US will need to establish a more robust sourcing strategy. Tungsten, known for its high melting point, hardness, density, and ability to conduct electricity and heat, is essential in various industrial applications, including drilling and nuclear fusion reactors. Currently,

The project describes using a WEMOS D1 Mini ESP8266 module and an Arduino sketch to modify an inexpensive analog quartz clock, allowing it to automatically display the correct local time. The ESP8266 connects to a Network Time Protocol (NTP) server to retrieve the time and refreshes the clock's time every 15 minutes, including adjustments for daylight saving time. To implement this, the clock's quartz movement needs modification: the internal coil must be disconnected from its oscillator, and wires are

The text discusses the question of what color the sky should be and how the color of any object is determined by the wavelengths of photons entering the eye. The primary point is that the colors we perceive are a result of different wavelengths of light, whether from a singular wavelength or a combination of many. For example, the color turquoise can arise from a specific wavelength (500 nm) or from combinations of other wavelengths. The sky appears blue because blue photons tend to scatter more when sunlight interacts with the Earth's atmosphere

Discord is implementing global age verification starting in March, automatically setting all user accounts to a "teen-appropriate experience" unless users prove they are adults. Age verification will primarily rely on account data rather than private messages. Non-verified users will face restrictions, including inability to access age-restricted servers, participate in "stage" channels, and will encounter content filters for graphic or sensitive material. Friend requests from unfamiliar users will trigger warning prompts, and direct messages from unknown users will be filtered into a separate

The content describes a late-night experience where the author, dealing with a PostgreSQL incident involving long query times and resource limits, seeks to understand the process of how PostgreSQL reads data from disk. The author explores the layers of caching involved in data retrieval, emphasizing that when PostgreSQL needs a page of data, it checks several caches in a specific order. First, it looks in its own memory cache called shared buffers, which is set to 4GB by default. If the needed data is

The article describes the implementation of semantic search in SQLite using binary embeddings and Hamming distance, allowing for hybrid searches without relying on external vector databases. It highlights the capabilities of SQLite's FTS5 extension for text search but notes its limitations in combining keyword matching with semantic retrieval. Semantic search involves converting text into numerical vectors (embeddings) that represent meaning. While traditional embeddings use float32 values that require significant storage, binary embeddings quantize these values to single bits, significantly reducing storage needs and allowing faster
