The author delves into the magical world of divisibility problems in mathematics, specifically focusing on how to create polynomials that are always multiples of a given number. By using Pólya-Redfield counting and group actions, the author demonstrates how to construct such polynomials that are guaranteed to be divisible by a fixed number. Through examples involving […]
Celestial navigation, an ancient form of aviation navigation using stars, was integrated into aircraft like Lockheed’s SR-71 for precise positioning. However, with the rise of GPS, interest in celestial navigation decreased due to its perceived inaccuracy.

DeepSeek-R1 is a groundbreaking first-generation reasoning model that outperforms OpenAI-o1 across math, code, and reasoning tasks. DeepSeek-R1-Zero, trained via reinforcement learning (RL) without supervised fine-tuning, showcased impressive reasoning capabilities, although it faced challenges like poor readability. To address these issues, DeepSeek-R1 incorporates cold-start data before RL training, achieving performance comparable to top AI models. The […]
This week’s topic on Research-Driven Engineering Leadership explores how interruptions impact software engineers’ productivity and stress. Different types of interruptions, such as in-person and on-screen, can have varying effects on tasks like code writing, comprehension, and review. Surprisingly, in-person interruptions were found to have a positive impact on physiological measures, despite being perceived as more […]
8 FrontierMath was funded by OpenAI, but the communication about this connection was non-transparent. The mathematicians creating the problems were not informed about the funding, and contractors working on the dataset were also unaware. Epoch AI admits to the lack of transparency and commits to being more upfront in the future. OpenAI has access to […]
The author shares a surprising Git functionality where mistyped commands are autocorrected after a 0.1-second delay, suggested by the Git maintainer 17 years ago. Initially, unknown commands would prompt an error message, until a patch in 2008 introduced the autocorrect feature, later configurable via help.autocorrect. The setting can now be adjusted to immediately run the […]
