The author expresses confusion over how people often judge programming languages based solely on their declaration syntax, rather than considering other critical aspects like semantics. They assert that a language's character is not defined by its syntax, and that the semantics of a language remain largely unchanged even if its declaration syntax is modified. The author, who has a background in compiler design, emphasizes the importance of denotational semantics over operational semantics, particularly because many inexperienced programmers tend to overlook the deeper distinctions between languages, thinking they are merely

The document outlines the proposed C extension -fbounds-safety, designed to enhance memory safety by enforcing bounds checks to prevent out-of-bounds (OOB) memory accesses, a common cause of security vulnerabilities. Key features include bounds annotations that programmers can apply to pointers, such as __counted_by(N), which indicates the number of valid elements a pointer can access. The compiler then uses this information to implement necessary bounds checks during pointer dereferences, ensuring memory safety. The document details the programming model

The content discusses the challenges of storing and accessing data in a way that adheres to ACID (Atomicity, Consistency, Isolation, Durability) principles in SQL databases. It highlights MySQL, particularly with its default InnoDB engine, and PostgreSQL as examples of how different SQL databases implement ACID compliance. The text also introduces the concept of indexing, explaining that an index is a data structure that facilitates fast searching. In MySQL, every table possesses a Clustered Index (re

The architecture of compilers has evolved significantly over the years. Traditional compilers used a sequential pipeline that processed code in a series of passes, stopping at the first error and discarding any work done beforehand. In contrast, modern compilers have adopted a query-based model. Instead of running each pass to completion, users interact with the compiler through specific queries, such as asking for the parsed syntax tree, which prompts the compiler to perform necessary tasks, like lexing, dynamically. This model allows for multiple

The author describes an experiment comparing two large language models (LLMs), Claude and Gemini, by asking them to fix a specific bug in Express.js. Claude completed the task using 23,000 tokens, while Gemini used significantly more at 350,000 tokens. To analyze and understand this discrepancy, the author developed a tool called Context Lens, which tracks the content in the context window of LLM API calls. Tokens, which represent pieces of information (about 4 characters in English text), are

This article is Part 2 of the "Karafka to Async Journey" series, following the introduction of WaterDrop's support for asynchronous processing using Ruby's async ecosystem in Part 1. The focus here is on migrating the producer polling engine to a file descriptor-based polling system to enhance efficiency. In September 2025, the integration of async/fiber support showed promising results, as fibers outperformed multiple producer instances while using less memory. However, the original design resulted in each WaterDrop producer creating

The article discusses the balance between divergence and convergence in modern software development, inspired by insights from Khalil Stemmler. It highlights how software systems evolve faster than teams can adapt their understanding, leading to a decline in confidence as tests become less effective. Divergence represents the phase of exploration and experimentation, where various ideas are generated and assessed without the pressure of correctness. In contrast, convergence involves making deliberate decisions that create structure and constraints within the system, essential for maintaining its integrity against future changes. The article

Nvidia’s RTX 5090 is highlighted as the fastest consumer GPU, offering 104.8 TFLOPS of FP32 (single-precision) compute but only 1.64 TFLOPS of FP64 (double-precision) compute, resulting in a 64:1 ratio. This disparity has widened over the last 15 years, not due to technological limitations but as a strategic shift by Nvidia. Since the Fermi architecture in 2010, the FP64:FP32

Artificial intelligence (AI) is poised to transform global economies, but concrete data on its impact in Europe is limited. A study analyzing survey data from over 12,000 European firms reveals that AI adoption boosts labor productivity by an average of 4% in the EU without short-term job losses. However, the productivity benefits are not uniform; medium and large firms, along with those investing in intangible assets and human capital, see significantly greater gains. Europe is at a crossroads in the AI landscape, facing

The content discusses the development of the a3 framework for creating Advanced Automated Analysis engines, specifically the a3-python verifier for Python. This project aims to address the challenges of scaling program verification to mainstream languages like Python, which is known for its complexity. Traditional verification tools struggle to keep up with evolving language features and the complexities of type systems. Despite the effectiveness of LLM-based code synthesis, it lacks unambiguous semantics, making it an unreliable source. However, combining agent-driven code synthesis with robust
