The article discusses the common task of working with intervals in programming, which is relevant for scenarios like time ranges and geometric computations. It emphasizes that checking for the absence of overlap between intervals is generally simpler than detecting overlapping conditions. The post begins by explaining how to represent intervals in code, using the format [start, end] for closed intervals and [start, end) for half-open intervals, highlighting that the latter is frequently used in programming languages. Using Python and focusing on integer-valued intervals, the

The author discusses a frustrating experience they had with an email from a website that claimed to transform their scientific paper, “Neural spine bifurcation in sauropod dinosaurs of the Morrison Formation,” into an analogy. The email suggested comparing the bifurcation of neural spines to river deltas, a comparison the author dismissed as nonsensical. They expressed annoyance at the request to pay for premium access to view further content based on this flawed analogy. The author notes that while AI can be useful

On February 10, 2025, DigitalSociety revealed that they reduced their cloud expenses by 76% while increasing capacity by migrating from AWS and DigitalOcean to Hetzner. Previously, they utilized AWS for core hosting needs, including DNS and email services, because of their familiarity and reliability over 15 years. They also hosted their SaaS product, Tap, on AWS using various services for container orchestration and databases. Additionally, DigitalOcean Kubernetes was used for lightweight services and monitoring due

The article discusses the availability of a 'classic' edition suitable for those using accessibility tools or older browsers, along with the availability of its content in printed compilations and eBooks, which are DRM-free. These printed editions, available in bookstores and online, support the development of new articles. It provides a detailed examination of Sony's 2006 launch of the PlayStation 3, which features the advanced Cell Broadband Engine, reflecting a focus on vector processing despite its complexity. The article offers an

The article discusses "Copy-and-patch Compilation," a method for creating a baseline Just-In-Time (JIT) compiler that allows for rapid runtime code compilation while being easy to maintain. This approach requires minimal knowledge of assembly language and generates native code comparable in quality to traditional baseline JITs, which focus on quick code generation rather than deep optimization. The process involves defining "stencils," which are small C functions that perform specific operations, compiling them into native code, and then patching them

The provided content appears to be a portion of a PDF file encoded in binary format. As such, it contains metadata structures, compressed data, and is not meant to be directly interpreted as human-readable text. The PDF format includes objects like streams and compressed content, which often represent images or binary data following encoding standards. Without specific readable text or context, it's impossible to summarize its content meaningfully beyond noting its technical structure as part of a PDF document.

The Aisuru botnet, now primarily fueled by compromised Internet-of-Things (IoT) devices from major U.S. Internet providers like AT&T, Comcast, and Verizon, is causing significant concern due to its record-breaking attack capacities. Since emerging over a year ago, Aisuru has eclipsed other IoT-based botnets, drawing from around 300,000 infected devices globally, including consumer-grade routers, cameras, and digital recorders that often use outdated or insecure software.

On October 7, 2025, the React team announced the first stable release of the React Compiler, a tool designed to optimize React and React Native applications automatically without requiring code rewrites. This compiler has been thoroughly tested on major Meta applications and is now production-ready, incorporating automatic memoization to enhance performance. The development of the React Compiler represents nearly a decade of engineering effort, beginning with the Prepack project in 2017, which ultimately influenced the design of Hooks. Since its initial

Turbo Stream elements are custom HTML components that modify the DOM when included on a page. The <turbo-stream> tag allows for seven different actions that can manipulate the DOM: append, prepend, replace, update, remove, before, and after. For instance, after a user submits a form to create a new book, the server can respond with a <turbo-stream action="append"> element containing the new book entry, which Turbo then adds to the DOM. Two main questions arise: how

The 2025 DORA Report highlights that while AI adoption in software engineering is nearly universal, with 90% of respondents using AI tools and over 80% believing it enhances productivity, these beliefs can be misleading. Studies indicate that while developers feel AI tools improve their efficiency by 20%, they might actually slow them down by 19%. Additionally, gains in individual coding speed do not always translate to improved productivity throughout the software delivery lifecycle, which remains hampered by systemic obstacles such as unreliable pipelines

The author reflects on the difference between proving algorithm correctness in academia and the reliance on testing in the software industry. While testing can ensure that an application works with specific examples, it cannot guarantee that it functions correctly in all scenarios. The complexity of real-world software is often cited as a reason for this disparity, leading some to liken software behavior to biological processes, which lack predictability. However, the author emphasizes that software is ultimately deterministic, meaning consistent inputs will yield the same outputs. They argue that

The text discusses the challenges of integrating Lisp, a tree-based programming language, with ed(1), a line-oriented text editor. The author expresses a desire to combine these two "wolves" in their programming identity but acknowledges the difficulties due to their differing structures. Lisp typically requires a more complex syntax with nested parentheses, making it unsuitable for line editing in ed. The author suggests a potential solution: transforming Lisp code into a more line-oriented format by isolating self-contained forms on their own lines, inspired

The author discusses the evolving landscape of programming, suggesting that it is a temporary phase as artificial intelligence (AI) increasingly assumes programming roles. Drawing from science fiction, particularly "Star Trek," the author notes that characters interact with advanced computers without engaging in programming activities. Instead, users communicate their needs directly to AI, which intuitively understands and executes tasks without requiring coding. The piece highlights that, in many futuristic narratives, technology is depicted as self-sufficient, with programmers becoming obsolete and replaced by roles focused

The content discusses the evolving landscape of machine learning (ML), particularly in the realm of natural language processing (NLP) and the use of large language models (LLMs). A senior ML engineer expressed frustration on Reddit about their job being reduced to calling APIs from major model providers instead of doing hands-on ML work. Andrew Ng reinforced this notion, stating that training a sentiment classifier is no longer practical when existing APIs can achieve equal or better results quickly and at a low cost. However, the use of
