Approximating Float Multiplication with Bit Manipulation: A Neat Trick

This article explores a clever method for approximating float multiplication using bit manipulation. The approach involves casting floats to integers, adding them, adjusting the exponent, and casting back to a float. While this method fails catastrophically with exponent overflow or underflow, its accuracy is surprisingly good for most cases, staying within 7.5% of the correct result. The author delves into the underlying principles, explaining why simple addition can approximate multiplication. Although likely less efficient than native float multiplication in practice, its simplicity and potential for power savings in specific scenarios make it an interesting exploration.

A Flawed Falsification: Re-examining the Real-Number Quantum Theory Experiment

2025-09-17

Renou et al.'s 2021 Nature paper claimed that quantum theory based on real numbers can be experimentally falsified. This post argues otherwise. The paper proposed a test to distinguish between a full quantum gateset using complex numbers and a real-only subset. However, the author demonstrates that a real-only quantum computer, leveraging entanglement, can pass the test. The crucial, hidden assumption is that participating quantum computers begin without entanglement—a detail buried in the supplementary materials, severely undermining the experiment's validity.

The Reliability of Old Tech vs. the Complexity of Modern Tech

The author contrasts the reliability of older technology with the complexities of modern "smart" technology, using a 41-year-old TI-99/4A home computer as an example. The old computer boots instantly, requiring no updates, cloud connectivity, or subscription fees, showcasing straightforward computing. In contrast, the author's Google Nest router fails to connect after an update, rendering smart bulbs unusable. The article criticizes the modern tech industry's conflation of complexity with progress, highlighting over-reliance on abstraction and layered software architectures, making systems difficult to understand and repair. The author argues that the hype surrounding AI reflects this "forgetting," where statistical advancements are overblown as revolutionary breakthroughs, neglecting underlying principles. Ultimately, the author calls for a return to simple, reliable design, emphasizing the importance of understanding fundamental knowledge and principles, avoiding dependence on tools at the expense of technical mastery.

CDC Halts Collaboration with WHO, Immediately

The U.S. Centers for Disease Control and Prevention (CDC) has abruptly ordered an immediate end to all collaborations with the World Health Organization (WHO), sending shockwaves through the global public health community. This isn't a phased withdrawal; it's an immediate and complete cessation of all interactions, including work with technical working groups, coordinating centers, and advisory boards. Experts express deep concern, warning that this will severely hamper efforts to investigate and control outbreaks like the Marburg virus and mpox, potentially jeopardizing global health security. While President Trump had previously issued an executive order to begin the U.S. withdrawal from WHO, this sudden action is far more drastic and unexpected, sparking widespread worry and criticism.

NotaGen: An AI Composer Mastering Classical Music via Reinforcement Learning

NotaGen, an AI music generation model, is pre-trained on 1.6 million pieces of music to learn fundamental musical structures. It's then fine-tuned on a curated dataset of 8,948 classical music scores, enhancing its musicality. To further refine both musicality and prompt control, the researchers employed CLaMP-DPO, a reinforcement learning method using Direct Preference Optimization and CLaMP 2 as an evaluator. Experiments showed CLaMP-DPO effectively improved both controllability and musicality across various music generation models, highlighting its broad applicability.

Angel Investor Hits Pause After 15 Years: A Deep Dive into the Why and What's Next

After 15 years and 54 investments, an angel investor decided to pause his angel investing activities. He found that over-diversification led to superficial founder relationships, limited learning opportunities, and returns that didn't justify the time commitment, risk, and opportunity cost. His future plans involve deeper founder engagement through board positions, learning through podcasting and teaching, and becoming an LP in VC funds. He concludes that sometimes, the best investment decision is not to invest at all.

Rethinking Programming Education: Towards Visual and Understandable Programming

2025-08-04

This essay critiques the shortcomings of current "live coding" environments, exemplified by JavaScript and Processing, in programming education. It argues that these environments fail to effectively support powerful ways of thinking and don't allow programmers to see and understand program execution. The author proposes that understanding program flow and data state is key to learning programming, advocating for visualization techniques like timelines and data visualization to make the process more transparent and understandable. The importance of programming language design is also stressed, promoting metaphors closer to human thought processes and more easily understandable syntax. The essay emphasizes decomposition and recomposition methods to encourage creative learning.

Utah Bill Demands Transparency for AI-Generated Police Reports

Utah Bill Demands Transparency for AI-Generated Police Reports

A Utah Senate bill (S.B. 180) would mandate disclosure when police reports are generated by AI. The bill requires police departments to establish AI usage policies, including disclaimers on AI-generated content and officer certification of accuracy. This follows the rapid spread of Axon's Draft One, which uses bodycam audio to create reports. Critics warn of AI's potential to misinterpret language, provide plausible deniability for officers, and compromise justice. King County, Washington prosecutors have already instructed officers to avoid using the technology. While a step towards regulation, stronger oversight is needed to address the concerns surrounding AI in law enforcement.

Reproducing OpenAI's o1: A Roadmap from a Reinforcement Learning Perspective

A new paper explores the path to reproducing OpenAI's enigmatic model, o1, from a reinforcement learning perspective. Researchers argue o1's powerful reasoning isn't due to a single technique, but rather the synergy of four key components: policy initialization, reward design, search, and learning. Policy initialization equips the model with human-like reasoning; reward design provides dense and effective signals guiding search and learning; search generates high-quality solutions during training and testing; learning utilizes data from search to improve the policy, ultimately achieving better performance. This paper offers valuable insights into understanding and reproducing o1, providing new avenues for LLM development.

El Salvador Ditches Bitcoin as Legal Tender: A Failed Economic Gamble

El Salvador Ditches Bitcoin as Legal Tender: A Failed Economic Gamble

El Salvador, the first country to adopt Bitcoin as legal tender in 2021, has reversed course. President Nayib Bukele's economic gamble has failed, with Bitcoin never gaining widespread adoption among Salvadorans and the planned Bitcoin City remaining unbuilt. A revised Bitcoin Law removes the definition of Bitcoin as 'currency,' though it remains 'legal tender,' effectively allowing refusal of Bitcoin payments. This reform was a key condition for El Salvador to receive a $1.4 billion loan from the International Monetary Fund (IMF). While the government claims it will continue holding Bitcoin reserves, the move is criticized for its lack of transparency and highlights flawed economic decision-making by the Bukele administration.
