Swift is a general-purpose programming language known for its safety, performance, and ease of use, but it has struggled to extend beyond mobile development into broader workflows, particularly in scripting. Historically, scripting in Swift has been challenging and not user-friendly, diminishing its practicality even for simple tasks. However, a new package called swift-subprocess, released recently, aims to address these issues and improve the scripting experience. The article plans to explore what scripting entails, why it's been difficult in Swift, and how

Programming languages have rapidly evolved, but software development often still relies on outdated interfaces for runtime parametrization using environment variables (envvars). These envvars lack organization and types, existing as a flat global dictionary of strings. They are passed from parent processes to child processes during execution via the execve system call on Linux. While most tools (like Bash and Python) naturally pass the parent environment to children, some, such as the login executable, create a fresh environment. The environment is managed in a static

The author discusses the tension between writing terse code and prioritizing accuracy when using large language models (LLMs) for coding in q/kdb+. Traditionally, the q/kdb+ community values concise code; however, the author, influenced by LLM capabilities, argues that clarity and performance take precedence over terseness. An example illustrates the complexity of constructing an identity matrix in both q and Python, with a detailed breakdown of how the Python code works. The author concludes that while LLMs can write

The Dutch government has taken control of Nexperia, a semiconductor maker owned by China's Wingtech Technology, to secure the availability of essential chips in Europe amid rising global trade tensions. Nexperia, which produces chips for automotive and consumer electronics, is crucial for Europe's technological supply chains. The Dutch government invoked the "Goods Availability Act" to prevent potential shortages of Nexperia's products during emergencies. This decision followed concerns over significant governance issues within Nexperia that threatened its operational continuity and European economic

Search engines do not process text as whole sentences or individual words; instead, they break down user input into smaller, more abstract elements called tokens. These tokens are generated through a pipeline that includes various stages of cleaning and transformation, which ultimately prepares the text for effective searching. Using the example sentence "The quick brown fox jumps over the lazy dog," the process involves steps like lowercasing letters and normalizing characters by removing accents, ensuring consistency in how terms are indexed and searched. This approach allows

The author has spent the past year researching language and diffusion models in software businesses and is puzzled by the widespread belief that chat-based language models exhibit intelligence. They argue that large language models (LLMs) lack any intrinsic mechanism for reasoning or thinking, noting that they are merely mathematical models that generate plausible text responses based on input. The idea that LLMs think or reason is a misconception, and this belief is explored in the author's book titled "The Intelligence Illusion." The author suggests that the perception

The Coder Cafe explores database isolation levels, highlighting their importance for software engineers dealing with concurrent transactions. Isolation levels determine how transactions are separated from one another, with higher levels preventing more anomalies, such as dirty reads and writes. - **Read Uncommitted**: Prevents dirty writes. - **Read Committed**: Prevents dirty reads and dirty writes, building upon the previous level's protections. Higher isolation levels enhance data integrity but can significantly impact performance, sometimes reducing throughput by up to
