The article discusses the evolution of logging in Rails applications, highlighting that while many developers have moved to structured logging with tools like Lograge or Semantic Logger, there remains a challenge in tracking business events such as user signups and order completions. Currently, developers often resort to custom solutions or various tools that do not effectively meet their needs. To address this, Rails is working on a native event reporting system, which would integrate event tracking directly into the framework. This system, referred to as Rails.event,

In April 2025, Microsoft updated Copilot Enterprise to include a live Python sandbox utilizing Jupyter Notebook, enabling code execution in the backend. The sandbox allows easy execution of predefined commands using Jupyter syntax. However, the assistant's responsiveness can vary based on its 'mood', likened to that of a child — sometimes enthusiastic, and other times reluctant or overly explanatory. The sandbox operates under the 'ubuntu' user in a miniconda environment, which is part of the sudo group, although

The content is an introduction to a guide aimed at optimizing slow queries in Postgres databases by utilizing indexing. It emphasizes that many slow queries can be improved simply by adding the appropriate indexes. The guide promises to help users detect, prioritize, and create the necessary indexes using core catalog views and SQL, without needing any additional extensions. The phrase “Most slow queries are just an index away from being fast” encapsulates the main takeaway.

The article discusses the challenges of implementing anti-aliasing with Signed Distance Functions (SDFs). While many practitioners use various methods, including hardcoded constants and complex formulas, the topic is more nuanced than it appears. An SDF is defined as a function (or a texture lookup) that returns the signed distance from a point to a shape, indicating if the point is inside or outside. The author emphasizes the importance of understanding the conventions used for SDFs, particularly the sign representation of points

Idempotence is a key concept in system design, meaning that performing an operation multiple times yields the same result as performing it once. For example, pressing an "on" or "off" button is idempotent; pressing "on" multiple times keeps the machine on, and similarly for "off." In programming, idempotency is about the effect on state rather than the response status code. A common misunderstanding is that the response can indicate non-idempotency, but it’s the result

The content recounts an idea conceived during RailsConf 2025 about creating a "Passive Job" library that serves as a queue backend for Rails applications. The authors, inspired by ongoing discussions about optimizing job processing in Rails, propose the concept of "Passive Queue" that aligns with existing tools like ActiveJob, yet focuses on non-execution rather than performance. It suggests that the best job is one that is never executed, advocating for a more relaxed and contemplative approach to software development. The concept

The provided content appears to be a fragment of a PDF file, likely including binary data and stream information along with some encoded or compressed text. The text contains encoded characters and symbols, indicating it is not meant to be read in a conventional manner but rather processed by software that can handle PDF formats. This type of content typically includes metadata, graphic instructions, and potentially various document elements, but due to its binary nature and usage of compression (like FlateDecode), it cannot be summarized in a straightforward way

The author reflects on their enjoyment of the Discworld novels, particularly the character Rincewind, who faces a paradoxical situation regarding his exam scores. Rincewind must attain an exact score to continue receiving his father's financial support while avoiding being considered a passing wizard by the university. This ironic scenario illustrates that to be "lazy" (by not passing), he must put in more effort studying than if he were to simply pass the exam. The author connects this theme to the concept of laziness as

The content discusses the collaborative platform Stack Overflow for Teams, which enables users to ask questions, find answers, and share knowledge in a structured manner. It mentions a specific closed question regarding the appropriate percentage of code coverage for unit tests, inviting a thoughtful response rather than a subjective number. The excerpt includes a humorous narrative by Alberto Savoia about the importance of writing good tests over focusing solely on coverage, illustrated through a conversation between a programmer and a master. The master uses analogies to demonstrate that the

In the 2010s, the mobile landscape was dominated by the "mobile-first" trend, compelling businesses to push app downloads, despite many apps being underwhelming compared to their website versions. By 2025, the push to download apps has intensified, characterized by aggressive tactics from services like Reddit and LinkedIn to encourage users to switch from web browsers to apps. The main driving force behind this shift is access to data; apps can collect much more information by requesting various permissions from users,

Jono Alderson, an independent technical SEO consultant, argues that native CSS transitions have diminished the need for single-page applications (SPAs) in web development. He critiques the common belief that SPAs are essential for providing a fluid user experience, asserting that this assumption is now outdated. Many SPAs, often built with frameworks like React or Vue, require excessive JavaScript to simulate seamless navigation, which ultimately hampers performance and SEO. Alderson highlights that this reliance on JavaScript leads to bloated

The Rotring 600 ballpoint pen is a high-quality, all-metal writing instrument based on the classic Rotring 600 design. It utilizes a standard Parker-style refill with a clicker mechanism that operates crisply but can be noisy, potentially bothering those nearby. The pen closely resembles the Rotring 600 mechanical pencil, with minor differences in nib units and barrel lettering. While the pen is generally reliable and well-regarded, the reviewer experienced an issue with the original Rotring refill, which broke

Tailwind Plus has introduced a significant update that makes all its UI blocks fully functional and interactive without the need for JavaScript frameworks like React or Vue. This enhancement is possible due to the release of @tailwindplus/elements, a library designed for Tailwind Plus customers. The library contains headless custom elements that provide the necessary functionality for creating interactive UIs using only HTML, which can be styled with utility classes or custom CSS. These custom elements, such as <el-select> and <el

The author reflects on the decision to develop their own date parsing library after initially adopting Luxon for Eleventy in 2018. While Luxon met Eleventy's needs well, its lack of support for tree-shaking became a problem as Eleventy expands to different JavaScript environments. After evaluating alternatives, the author found dayjs to be inaccurate and noted the challenges posed by the ambiguity inherent in various date formats. This prompted a reevaluation of the necessity of dual publishing packages and a focus on the

In a discussion about MIT's switch from Scheme to Python for their introductory programming course (6.001), Sussman explained that programming has evolved significantly since 1980. In earlier times, good programming involved deep understanding and precision, akin to working with resistors. However, by the mid-90s and beyond, programming became more about dealing with complex, opaque software systems and libraries whose workings were not always clear. This shift necessitated a new approach to teaching programming, leading to the robot
