In the past year, advancements in robotics have progressed alongside the era of large language models (LLMs). Notable examples include Pi’s π0.5, capable of cleaning unfamiliar homes, and Tesla's Optimus, which can follow cooking instructions given in natural language. Despite their impressive capabilities, these robots exhibit a functional and utilitarian approach, lacking expressiveness, which is essential for meaningful human-robot interaction. Expressiveness conveys internal states such as intent and confidence, making interactions feel more natural and

The author describes their journey into electronics inspired by a Tech Ingredients episode featuring a laser gimbal that tracks and shoots down drones using advanced motion control. They decided to explore these concepts by purchasing the Elegoo Arduino Uno R3 Starter Kit, which includes over 200 components and a tutorial. Although the author has a background in electronics, they had not yet performed the basic task of lighting an LED, which sparked their curiosity about RGB LEDs and pulse width modulation (PWM). This technique allows control of LED brightness

In his piece, Tom Renner discusses the challenges of debating against skilled debaters and emphasizes the importance of framing an argument in one’s own terms to succeed. He references insights from Professor Shoshana Zuboff’s book, "The Age of Surveillance Capitalism," where he learns about new concepts that help articulate complex ideas. One key term he highlights is “inevitabilism,” which suggests that some believe a particular future is unavoidable. This perspective can dismiss opposing views as unrealistic, limiting discussions

The LIGO-Virgo-KAGRA (LVK) Collaboration has detected the merger of the largest black holes ever observed via gravitational waves, producing a black hole approximately 225 times the mass of the Sun. The event, known as GW231123, occurred during the LVK's fourth observing run on November 23, 2023. This merger surpasses the previous record held by the 2021 event GW190521, which had a total mass of 140 solar masses. The

The author describes the foundational design principles behind Looping, emphasizing the importance of simplicity and independence in system components to avoid complexity and hidden dependencies. Central to this architecture is the concept of composable services, which are small, focused units designed to perform a single task, accepting input and providing a clear output (either Success or Failure). This approach promotes reusability, flexibility, and clarity as the system scales. Each service inherits from the ApplicationService, which enforces a consistent interface, allowing for easy

The 1997 Workshop on Implementing Functional Languages discussed the growing trend of research compilers using C as a target code language, leveraging C compilers to produce machine code. While this approach simplifies the implementation of complex compiler components like register allocation and instruction scheduling, C's design as a programming language makes it ill-suited as a compiler target language. To address this issue, the concept of C– was introduced as a portable compiler target language, aiming to balance the needs of high-level backend processes with

Daniel Lemire's blog focuses on software performance, where he emphasizes the significance of data alignment in memory processing. Citing his recognition as a top scientist and a leading developer on GitHub, he explores the practical implications of data alignment in his experiments. Lemire discusses how compilers often align data structures and questions whether this alignment truly impacts performance. He conducted tests using a program that initializes a long array and computes a hash value with different offsets from aligned boundaries. His findings indicate that unaligned data processing

The author expresses a deep appreciation for Programming Language Theory (PLT), highlighting its beauty and the valuable ideas it encompasses, yet notes that it is often misunderstood and deemed impractical by outsiders. This perception mirrors that of pure mathematics, leading to questions about its relevance and applications. The author explains that while PLT can be appreciated as a discipline of pure theory similar to mathematical constructs, it frequently faces challenges in communicating its practical implications. For instance, an experienced software engineer venturing into PLT may struggle
