WSPR (Weak Signal Propagation Reporter) is a digital communication protocol used by amateur radio operators to determine if propagation paths are open. It transmits beacon-like signals containing a callsign, location, and power level, utilizing a compressed data format with strong forward error correction (FEC) and narrow-band frequency-shift keying. The protocol is designed to operate effectively even at low signal-to-noise ratios and allows multiple signals to coexist in a narrow frequency range. To use WSPR, operators

The blog post discusses Just-In-Time (JIT) compilation, specifically its application in ClickHouse and its implementation using the LLVM infrastructure. It summarizes the author's presentations from various conferences where JIT compilation in ClickHouse was a primary focus. JIT compilation allows for dynamic generation and execution of machine code at runtime, with examples including JVM Hotspot and V8. The post also includes a practical example of a sum function coded in C++, detailing how the function is compiled and how to analyze its assembly output

The article discusses how databases typically manage their write operations using direct and buffered I/O techniques. Most databases open their Write-Ahead Logging (WAL) and data files with the `O_DIRECT` flag for unbuffered I/O, allowing them to maintain their own page cache and directly interface with disk without involving the kernel's page cache. This method gives databases more control over data management and improves durability through functions like `fdatasync()`. The piece notes that while `O_DIRECT` is generally

Codebuff streamlines code editing by allowing users to type their requests directly into the terminal, after which it searches the entire codebase to make the necessary edits, manage tests, type-check, or install packages. The idea originated during a hackathon when the creator experimented with Sonnet 3.5, initially creating a flawed script that required multiple steps for code modification. However, by reflecting on the errors and providing more context about the codebase through a manually written guide, the script's performance improved

The author is developing a static analysis tool for SQL, specifically for SQLite, called sqleibniz. The tool aims to perform syntax checks, verify the existence of tables, columns, and functions, and enhance the development experience by incorporating an embedded SQLite runtime for condition assertions. The goal is to provide users with high-quality error messages that offer context, explanations, and options to mute diagnostics. The analysis process includes lexical analysis/tokenization, SQL parsing based on SQLite documentation, and evaluating the resulting constructs

The content explains the distinctions between four key attributes of system design: resilience, fault-tolerance, robustness, and reliability. 1. **Resilience** refers to a system's ability to recover after a disruption, likened to a rubber band that returns to its shape after being stretched. An example is Apache Cassandra's mechanism to recover missing data after a node failure. 2. **Fault-tolerance** is the capacity of a system to continue functioning properly despite one or more component failures, represented by

The Plasma Control Group addresses the challenges of understanding complex non-linear systems in plasma physics using a novel machine learning approach. Traditional diagnostics provide limited views of these systems, often losing crucial information. By identifying hidden inter-correlations among different diagnostics, the group proposes a multimodal methodology that produces super-resolution data, allowing for detailed observation of plasma dynamics and structure previously deemed unobservable. This approach is particularly significant for analyzing Edge Localized Modes (ELMs), which can damage fusion reactor walls. The new super-resolution
