The article discusses a successful attempt to send 20,000 requests per second from a single Python application, challenging the common belief that Python lacks the performance for such high-throughput tasks. The author combined an asynchronous Python script with a Rust-based library, rnet, which leverages the Rust library wreq, to achieve this performance. The rnet library offers improved TLS configuration, helping to bypass Web Application Firewalls (WAFs) that could hinder standard Python clients. The script employs asyncio to

The text discusses the challenges of evaluating software developers using intelligence tools, specifically criticizing the desire for a simple metric to identify the "worst developer." It highlights the complexity of software development and the inadequacy of methods like stack ranking, which can lead to negative consequences such as gaming the system and knowledge hoarding. In the current economic climate, pressure on engineering leaders to justify expenses has increased, making the appeal of stack ranking attractive for making difficult headcount decisions. However, the author argues that such methods

Christopher Alexander's "The Timeless Way of Building," published in 1979, is a seminal work in architectural theory that explores the patterns that create emotionally resonant and harmonious spaces. It introduces the concept of "quality-without-a-name," which describes the intangible essence that makes certain buildings and places feel alive. Alexander emphasizes that this quality can be intentionally designed rather than left to chance, advocating for the use of timeless design patterns that have been effective throughout history and across cultures. The book's insights

A study led by researchers at the Université de Montréal has discovered that a fetus can begin to recognize a foreign language before birth. Prenatal exposure to a foreign language can rewire the language-processing networks in a newborn's brain, allowing them to process that language alongside their mother tongue. The research, published in *Communications Biology*, involved 60 native French-speaking pregnant women who played recordings of stories in French and either German or Hebrew to their babies in the womb. The choice of these specific languages

The article discusses the common issue of over-engineering CSS solutions, which can complicate web design and lead to problems. Kevin Powell emphasizes that a simple approach can yield a decent-looking responsive website with minimal CSS. Starting with basic HTML can result in a responsive layout, although images may cause overflow issues. To improve aesthetics, he suggests changing the default font to a system UI font for better universal appeal and increasing the font size and line-height for readability. Additionally, enabling a color scheme based on user

The post discusses a surprising realization that a famous grammatically correct sentence can be implemented in C++. This topic emerged during a conversation at CppCon 2025 about Clang’s -Wdtor-name error. The author is intrigued by the concept and seeks to understand how the Abstract Syntax Tree (AST) of different code snippets can be equivalent, as shown through tests using Clang, which produce the same AST for two different pieces of code. The author reflects on the idea of "injected class

OpenZL is a new data compression framework that provides lossless compression for structured data, achieving performance comparable to specialized compressors. It does this by utilizing a configurable sequence of transformations to reveal hidden order in the data, allowing for more effective compression. Despite employing different transformation methods for various file types, all OpenZL files can be decompressed using a single universal decompressor. The development of OpenZL is motivated by the limitations of existing frameworks like Zstandard, which, while improving over time,

The text discusses the criticisms architects face regarding the creation of extensive solution design documents that often become unwieldy and are seldom read. These documents can be excessively long, filled with sections that are either copied from other sources or marked as "not applicable," leading to disengagement from those tasked with completing them. The author advocates for more concise solution designs that prioritize essential information needed by the technical audience responsible for implementation. The key suggestion is to simplify these documents, keeping them lean while allowing for additional details as

Businesses aim to maximize profits by strategically pricing their products. Setting prices too low can result in lost profits, while high prices may exclude potential customers. Therefore, finding an optimal price that balances profitability and demand is essential. Global businesses, in particular, must consider regional pricing, adjusting prices according to each country's purchasing power, taxes, and tariffs to avoid mispricing that can lead to reduced profits. Many online services, including Netflix and Spotify, utilize regional pricing strategies. In the case of Chess.com,

The author discusses the often-overlooked `Random` module in the Ruby standard library, describing it as an invaluable tool for web application development, particularly when it comes to creating deterministic and testable environments. Unlike `SecureRandom`, which is tied to the operating system's entropy source and thus non-deterministic, `Random` uses the Mersenne twister algorithm to generate a sequence of pseudorandom numbers based on a seed. This makes `Random` particularly useful for applications that require repeat
