Sparse Interpretable Audio Codec: Towards a More Intuitive Audio Representation

2025-02-01

This paper introduces a proof-of-concept audio encoder that aims to encode audio as a sparse set of events and their times of occurrence. It leverages rudimentary physics-based assumptions to model the attack and physical resonance of both the instrument and the room, hopefully encouraging a sparse, parsimonious, and easy-to-interpret representation. The model works by iteratively removing energy from the input spectrogram, producing event vectors and one-hot vectors representing time of occurrence. The decoder uses these vectors to reconstruct the audio. Experimental results show the model's ability to decompose audio, but there's room for improvement, such as enhancing reconstruction quality and reducing redundant events.

Go's Surprising Memory Allocation Trap: A 30% Regression Story

2025-04-21

Go's Surprising Memory Allocation Trap: A 30% Regression Story

A seemingly innocuous refactoring in a Go project led to a 30% performance regression. The culprit was the `GetBytes` method of the `ImmutableValue` struct, which used a value receiver, causing a heap allocation on every call. Heap allocations are significantly more expensive than stack allocations. The root cause was the Go compiler's escape analysis being imprecise; it failed to recognize that the value receiver wouldn't escape. Switching to a pointer receiver fixed the problem. This case highlights the importance of understanding the Go compiler's memory allocation decisions and using appropriate receiver types for high-performance Go code.

Cilla's Low-Budget OB Inserts

2025-04-22

This new series of Cilla featured OB inserts produced cheaply, often piggybacking on other, usually sports, OBs in nearby locations. For example, the crew would film a sports event in Worcester and then immediately film Cilla inserts in the same location. Cilla would announce live that cameras were in a specific street, inviting residents to come out and say hello. The result was a floodlit street, PA system, and live interviews, all achieved with a remarkably low budget.

UK Fusion Firm First Light Fusion Pivots Away From Reactor Construction

UK-based nuclear fusion company First Light Fusion has suffered a 60% valuation drop after abandoning plans to build its first reactor due to funding issues. The company's 'projectile fusion' technology, involving firing a projectile at a fuel cell, proved too costly to develop into a power plant. Instead, First Light will now license its 'amplifier' technology, which boosts fusion reactions, to other nuclear power companies. This pivot aims for a more capital-efficient model and faster revenue generation. The decision comes amidst increased competition from China's advancements in fusion technology and highlights the challenges in commercializing this promising but complex energy source.

Erlang's Secret Sauce: It's Not Lightweight Processes, It's Behaviors

2025-04-11

This post revisits the core ideas behind the Erlang programming language. The author argues that Erlang's success isn't solely due to its lightweight processes and message passing, but rather its unique "behaviors." Behaviors are similar to interfaces in other languages; they provide a set of predefined function signatures. Developers only need to implement these signatures to gain access to advanced features like concurrency and fault tolerance. This allows developers to focus on business logic without dealing with low-level concurrency details. The post uses examples of gen_server, gen_event, and supervisor behaviors to illustrate their importance in building reliable distributed systems. It also explores how to adapt Erlang's behavior pattern in other languages to improve software reliability and testability.

CAPTCHA is Dead: The Ticketing Industry's Bot War

2025-05-25

Ticketing websites face a persistent challenge: bots used by scalpers to snatch tickets. Traditional CAPTCHAs, such as image and audio recognition, have been defeated by advanced machine learning. Behavior-based anti-bot technologies, while effective, compromise user privacy; while proof-of-work methods are too inexpensive for scalpers. The author proposes a "BAP theorem," stating that anti-bot systems can only satisfy two out of three properties: "bot-resistance," "accessibility," and "privacy." Ultimately, websites must choose between high privacy and high security; technical solutions alone are insufficient. Legislation and social approaches might be more effective.

MCPs: Who Controls the Future of AI?

This article delves into the potential and limitations of Model Context Protocols (MCPs). MCPs, standardized APIs connecting external data sources to LLMs like ChatGPT, empower LLMs to access real-time data and perform actions. The author built two experimental MCP servers: one for code learning, the other connecting to a prediction market. While promising, MCPs currently suffer from poor user experience and significant security risks. Critically, LLM clients (like ChatGPT) will become the new gatekeepers, controlling MCP installation, usage, and visibility. This will reshape the AI ecosystem, mirroring Google's dominance in search and app stores. The future will see LLM clients deciding which MCPs are prioritized, even permitted, leading to new business models like MCP wrappers, affiliate shopping engines, and MCP-first content apps.

Harvard Business School research suggests AI chatbots can alleviate loneliness. However, this raises concerns: are we repeating a pattern of solving one problem by creating a potentially worse one? Similar to how fast food addressed hunger but led to obesity, AI companions might offer convenient companionship, but they can't replace genuine human interaction, potentially leading to addiction and social skill degradation. The suicide of a 14-year-old boy due to excessive reliance on an AI chatbot serves as a stark warning.

Chang'e 6 Finds Moon's Far Side Surprisingly Dry

Analysis of lunar samples returned by China's Chang'e 6 mission suggests the far side of the moon may be drier than the near side. Scientists examined 578 particles from the South Pole-Aitken basin, estimating water abundance at less than 1.5 micrograms per gram—lower than previous near-side findings. While more samples are needed for conclusive evidence, the dryness could be linked to the basin's formation or variations in water distribution. This finding is unlikely to significantly alter NASA's plans to land astronauts near the lunar south pole, where abundant water ice is expected to support future missions.
