Building an LLM from Scratch: Unraveling the Mystery of Attention

Building an LLM from Scratch: Unraveling the Mystery of Attention

This post delves into the inner workings of the self-attention mechanism in large language models. The author analyzes multi-head attention and layered mechanisms, explaining how seemingly simple matrix multiplications achieve complex functionality. The core idea is that individual attention heads are simple, but through multi-head attention and layering, complex and rich representations are built. This is analogous to how convolutional neural networks extract features layer by layer, ultimately achieving a deep understanding of the input sequence. Furthermore, the post explains how attention mechanisms solve the inherent fixed-length bottleneck problem of RNN models and uses examples to illustrate the roles of query, key, and value spaces in the attention mechanism.

Linus Torvalds Returns to Clicky Mechanical Keyboard

Linus Torvalds, the creator of the Linux kernel, has returned to his trusty clicky mechanical keyboard after a six-month experiment with a quieter, low-profile alternative. He found the audible and tactile feedback crucial to reducing typing errors. Despite working from home, he initially blamed his recent typos on the keyboard (later shifting blame to autocorrect). Meanwhile, progress on the Linux 6.15 kernel release is proceeding smoothly, with a release expected in two weeks.

Is Another AI Winter Coming?

2025-05-19

This article explores the current state of artificial intelligence, arguing that current expectations are overly optimistic. From the failed machine translation projects of the 1960s to the limitations of Large Language Models (LLMs) today, the author contends that while AI finds application in specific areas like medical image recognition, it remains far from a true 'thinking machine'. LLMs suffer from 'hallucinations,' frequently generating false information requiring extensive human fact-checking, a significant gap between reality and hype. Current AI applications in customer service and code assistance show promise but their profitability and broad applicability remain unproven. The author suggests that given the changing economic climate and inherent limitations of the technology, the AI field may face another 'winter'.

Microsoft's C/C++ Extension Breaks VS Code Forks, Sparks Antitrust Concerns

Microsoft's recent update to its Visual Studio Code C/C++ extension has broken compatibility with derivative products like VS Codium and Cursor, prompting outrage from developers. The move is seen as anti-competitive, as Microsoft restricts its extension's use outside its own products while simultaneously promoting its own AI coding assistant, Copilot. Developers have filed complaints with the US Federal Trade Commission, alleging unfair competition through bundling Copilot, blocking rivals like Cursor, and locking users into its AI ecosystem. Cursor is reportedly transitioning to open-source alternatives.

The Missing Link: How Translation is Neglected in Literary Reviews

This article examines the oversight of translated works in English-language literary reviews. The author surveyed reviews of translated literary fiction and poetry in prominent journals in 2023, finding many reviews lacking in attention to the translation itself. Many simply praise the translation as 'fluent' or 'elegant' or ignore it entirely. The author argues that good reviews should delve into the translator's choices, challenges, and understanding of the source text, illustrated with specific examples. Only then can readers fully appreciate the value of translated works and the art of translation.

Why Computer Scientists Consult Oracles

Computational complexity theorists use hypothetical 'oracles'—devices that instantly answer specific questions—to explore the fundamental limits of computation. By studying how different oracles affect problem difficulty (e.g., the P vs. NP problem), researchers gain insights into inherent computational limitations and inspire new algorithms. For example, Shor's algorithm, a quantum algorithm for factoring large numbers crucial to modern cryptography, was inspired by oracle-based research. Oracles serve as a powerful tool, pushing the boundaries of theoretical understanding and driving innovation in fields like quantum computing.

AI's Energy Hunger: Data Center Power Consumption to Double by 2030

A new report from the International Energy Agency (IEA) reveals that data center electricity consumption is projected to more than double by 2030, primarily driven by Artificial Intelligence (AI). The report forecasts data centers will consume 945 terawatt-hours (TWh) in 2030, roughly equivalent to Japan's current annual electricity consumption. AI servers already accounted for 15% of total data center energy demand in 2024. While developing economies are projected to account for only 5% of future growth, advanced economies will contribute over 20%. The IEA estimates that 20% of planned data centers might face grid connection delays. Experts suggest the energy consumption of AI might be underestimated, highlighting the need to address the surge in global electricity demand.

The Fate of Gaelic and the Ossian Controversy

2025-04-23

2025 marks the 20th anniversary of the Gaelic Language Act (Scotland). Despite growing numbers learning Gaelic, its usage remains low due to the dominance of English. This article explores the 18th-century epic poems of James Macpherson, known as Ossian, and the controversy surrounding their authenticity. Macpherson claimed to translate ancient Gaelic texts, but their veracity has been debated for centuries. While Ossian profoundly influenced European Romanticism, it's not the sole or best representation of the Finn Cycle, a rich body of Gaelic oral and written tradition far older and more extensive than Macpherson's work. The article calls for prioritizing Gaelic community language preservation efforts, ensuring Gaelic and its cultural heritage thrive in a new era.

Layered Design in Go: A Weapon Against Circular Dependencies

2025-04-20

This post delves into the problem of circular dependencies in Go and offers solutions. The author points out that Go's prohibition against circular package imports inherently shapes program design, promoting a layered architecture. Analyzing package import relationships allows for decomposition into layers, where higher-level packages depend on lower-level ones, preventing circularity. Several refactoring techniques for handling circular dependencies are introduced, including moving functionality, creating new packages, and using interfaces. Minimizing exported package members is stressed. This layered approach not only avoids circular dependencies but also enhances code understandability and maintainability, making each package independently useful.
