Kroger has announced the closure of three automated fulfillment centers, signaling a significant shift in its grocery e-commerce strategy. This decision comes just months after the company expressed confidence in its partnership with Ocado, the U.K.-based warehouse automation firm. Initially, Kroger planned to expand its network of high-tech fulfillment centers and improve efficiency with new technology. However, recent assessments revealed that the Ocado network was not meeting performance expectations, leading Kroger to pause further developments. The closures, which also included

The author describes an experiment using an AI agent, Claude, to develop an app that estimates macronutrients in foods based on descriptions and photos. After creating a functional app, they conducted an extensive test by repeatedly running a script on their codebase, which led to significant code enhancements. Initially, the codebase contained around 20,000 lines of TypeScript, with nearly 10,000 lines for tests. After the iterative improvements, the total lines of code increased to 84,000,

The author expresses frustration with the default design philosophy of adding icons to every menu item in applications like Google Sheets and macOS. They argue that this approach creates unnecessary visual noise and reflects a lack of thoughtful design. The concern is that designers may feel compelled to fill spaces with icons rather than carefully considering whether each icon aids usability. The author contrasts this with Apple's previous approach in macOS, which did not adhere to a one-size-fits-all icon policy. However, recent updates, like macOS Tahoe

NATS is a distributed streaming system that typically offers best-effort message delivery; however, its JetStream subsystem provides a more reliable at-least-once message delivery. In testing the JetStream version 2.12.1, issues were identified, including data loss due to file truncation or corruption on a few nodes, and complications arising from power failures or single-node OS crashes combined with network delays. These problems stemmed, in part, from the decision to flush writes to disk every two

A magnitude 7.5 earthquake hit northern Japan on Monday night, with its epicenter off the eastern coast of Aomori Prefecture. The Japan Meteorological Agency initially reported a magnitude of 7.6 but later downgraded it. The tremor was felt strongly in Hachinohe, where it registered an upper 6 intensity on the Japanese scale. Six people in Aomori were injured due to falling debris. A tsunami warning was issued for Iwate and parts of

The article discusses the author's completion of a personal project inspired by the game TI Blasto, which involved enhancing the game's mechanics and gameplay. This project, part of the author's bucket list, took a couple of years to develop and features faster action, animated graphics, a variety of procedurally generated screens, and customizable gameplay settings. While the author appreciates the original TI Blasto, they aimed to improve upon it. One notable enhancement is the way the game now tracks explosions and animations more efficiently, avoiding

The content outlines the functionalities of MyCTiger, a tool that transforms the Ring programming language into a domain-specific language (DSL) for generating and building C programs. It emphasizes the importance of user feedback and provides documentation for available qualifiers. MyCTiger allows developers to harness the performance of C while utilizing the expressive syntax of Ring, focusing on compile-time code generation rather than runtime language integration. Key features include compile-time execution of Ring code, the ability to treat Ring as a meta-language for structuring

The text discusses the human tendency to anthropomorphize artificial intelligence (AI), attributing human-like qualities and intentions to it. When interacting with AI systems like ChatGPT, people instinctively apply their social understanding and faculties, such as theory of mind and impression management, expecting human-like responses. This tendency to mistake non-human entities for people has historical roots, serving as an adaptive mechanism in human evolution. The author points out that our struggles to understand AI's behavior—such as making up citations or

A rare hybrid bird, resulting from the mating of a male blue jay and a female green jay, has been discovered in suburban San Antonio, Texas. Researchers from The University of Texas at Austin believe this hybrid is one of the first instances of vertebrate hybridization due to climate-related range shifts of both parent species. Traditionally separated by about 7 million years of evolution and with non-overlapping ranges only a few decades ago, both species have expanded their habitats in response to changing weather patterns.

The article discusses the challenges and solutions in representing decimal numbers in computing, as most everyday numbers are non-integers and computers originally focused on integers. Different numeric formats have been developed over time to handle these representations, with no single solution fitting all domains. The "double" is highlighted as the most common numerical type in modern computing, widely used in scientific libraries, graphics engines, and machine learning frameworks due to its speed and efficiency. Defined by the IEEE-754 standard, a double is a

The article discusses an attempt to recreate the original 1996 Space Jam website using Claude, an AI developed by Anthropic. The author expresses frustration with their inability to successfully prompt Claude for this task and seeks help in preserving the retro website, which Warner Bros still hosts as a nostalgic piece of internet history. The author plans to track Claude's interactions through a man-in-the-middle proxy to analyze the AI's performance better. They refer to their technical background as an engineering manager with a computer science degree,

A Guardian investigation has uncovered that Dollar General and Family Dollar frequently fail to honor their shelf prices, leading customers to be charged more at checkout for various items. During an inspection in Windsor, North Carolina, state inspector Ryan Coffield scanned 300 items, finding a 23% error rate with prices ringing up higher than displayed—far exceeding the state's acceptable limit. Items like frozen pizzas and paper towels were among those mispriced, and the store had failed inspections consecutively with fines imposed for previous violations.

The content discusses the differences between mutexes and spinlocks as synchronization primitives in programming. It highlights how engineers often fall into the "synchronization primitive trap" by choosing the inappropriate primitive for their scenario. Mutexes allow threads to sleep, which is beneficial for short critical sections but can be detrimental when latency is critical. Spinlocks, on the other hand, keep the CPU busy while waiting, which can waste resources, especially in scenarios with contention. A spinlock uses a continuous loop with atomic operations

The content discusses how systems maintain their integrity and shape through constraints, comparing this to the surface tension of water that resists external pressure. In software, integrity is crucial; it allows systems to manage side effects and maintain coherence when changed. The text highlights the importance of type systems, invariants, and defined boundaries that specify what is allowed within a system, preventing ambiguity that could lead to instability. It explains that some systems are well-structured with clear rules that prevent errors, while others can become chaotic
