The article from the "That's Maths" column in The Irish Times highlights the mathematical principles behind the efficient packing of sunflowers and other plants, specifically focusing on the Fibonacci sequence. It begins with an observation of a plaque at the Ibec head office in Dublin, which features a circular dot pattern resembling a sunflower's head. The logo consists of 34 clockwise and 21 counter-clockwise spirals, corresponding to two sequential Fibonacci numbers. The Fibonacci sequence, introduced by mathematician Leonardo of Pisa (F

Denis Isaev shares experiences related to reliability issues caused by implementing retry mechanisms in a microservices architecture at Yandex Go, told through a fictional character named Ben. Ben, a backend developer on a taxi app's order platform, encountered user complaints linked to 500 errors due to timeouts in the pricing service. Believing these to be transient errors, he implemented three retries for failures, assuming it was safe due to the APIs being idempotent. During a code review, team lead Alex

In a 2004 interview at the Computer History Museum, Grady Booch spoke with early Apple developers Bill Atkinson and Andy Hertzfeld about software development, focusing on the creation of the original Apple Mac and MacPaint. Atkinson emphasized that software development is an art form that requires attention to beauty and clarity. He believes that making code readable and straightforward helps prevent bugs, contrasting his approach with others who valued complexity. He dedicated time to organizing and simplifying code, using intermediate variables to clarify its purpose

The content discusses the challenges faced by classic computer collectors, particularly regarding storage solutions for their hardware. Collectors often accumulate more items than they can store at home, leading many to rent storage units, sometimes in "cold" climate-controlled facilities for sensitive electronics, alongside conventional "hot" units for other items. The article highlights concerns about security in these units, sharing a personal anecdote about a prior theft at a facility with inadequate security measures. The author emphasizes the importance of better locks and security systems,

The author is developing a WordPress Plugin Mirror System as a proof of concept (POC) that began on October 2, 2024. This system aims to efficiently download, cache, and manage WordPress plugins, particularly as a fallback during WordPress.org downtime. It utilizes Cloudflare's edge computing and R2 S3 object storage for high-performance management. The project can be set up at low costs (starting around US$5.35/month) and is free for open-source projects

The article discusses the development of a novel construction material called CoRncrete, made from corn starch, sand, and water. This material takes advantage of starch's renewability and biodegradability, making it an appealing alternative for industrial applications, including bioplastics. CoRncrete is created by mixing the ingredients, which forms a self-compacting mixture when wet. After being poured into a mold, it is heated in a microwave or oven, triggering a gelatinization process that solidifies the mixture,

The author reflects on debugging practices while working on Bugsink, particularly emphasizing the importance of local variables in understanding exceptions and troubleshooting code. They argue that seeing local variable values in stack traces significantly aids debugging, which is a key feature of Bugsink. The narrative suggests that errors often occur not where they seem, but a few lines later, typically involving functions passing data that leads to exceptions. They illustrate this with an example involving the math.sqrt function, which raises exceptions for negative inputs. The overall message advocates

In October 2024, Tim recounts his journey of porting mainline Linux to his old Samsung Galaxy Core Plus phone, an obscure device from 2013. He initially pursued this project for experimental purposes, facing challenges such as a lack of direct feedback from the device and lengthy flash-and-test cycles due to the absence of fastboot on Samsung devices. Despite the Linux kernel having basic support for the Broadcom BCM21664 SoC used in the phone, getting it to run proved to be

Ziggy introduces a unique notation for key-value pairs, differentiating between application-controlled keys that require a schema and user-defined keys. It simplifies representing tagged unions through Ziggy structs, allowing easier identification of union cases. Tagged literals enable expressions like @date("2024-01-01") and @keys("crtl+c"). Its features include optional outer curly braces, multi-line strings, trailing commas, comments, and underscores in numeric literals. Ziggy schemas facilitate the definition of clear, valid

Approximately ten years ago, the author identified a bug in a vendor's compiler related to reading an asynchronous hardware timer. The timer, connected internally to a chip, presented a challenge because it wasn't synchronized with the MCU clock. This situation introduced a race condition, where reading the timer at the moment it increments could lead to a mix of old and new bits. The hardware vendor suggested reading the timer repeatedly until it returned the same value twice, indicating a stable reading. However, this method had a downside:

Vasek Rozhon discusses a recent Polylog video about the P vs NP problem that aimed to simplify the topic while omitting complex technical details. The video's unique framing asks, “If you can efficiently compute a function, can you efficiently compute its inverse?” This perspective is mathematically equivalent to the traditional question concerning verification and problem-solving efficiency. Rozhon believes this framing is clearer and highlights the foundational aspects of the P vs NP problem. He promises to provide a deeper explanation of the concepts in his
