On October 7, 2025, the author reflects on the evolution of software development influenced by AI, distinguishing between two approaches: "vibe coding," which is fast and careless, and a more responsible method they term "vibe engineering." The latter involves skilled professionals who leverage large language models (LLMs) to enhance their work while maintaining accountability for their software. The author notes that effectively using LLMs for substantial projects is challenging and requires deep understanding and careful navigation of potential pitfalls.

NumPy, a widely used package in the Python ecosystem, recently underwent significant improvements in its type-completeness score, rising from 33% to nearly 90%. This initiative, led by Quansight Labs with support from Meta's Pyrefly team, enhances the developer experience and promotes safer code in downstream libraries by leveraging static typing. Modern Integrated Development Environments (IDEs) utilize type annotations to provide useful suggestions and error highlighting, with Pyright being a popular type-checker that measures

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

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,
