Re-reading Neuromancer in 2025: A Cyberpunk Classic Reexamined

Reading William Gibson's *Neuromancer* for the first time in 2025, the author reflects on its groundbreaking impact on the cyberpunk genre. The book's depiction of AI, virtual reality, and cyberspace remains strikingly prescient, showcasing Gibson's visionary talent. However, the novel's omissions (like mobile phones) and assumptions (massive space stations) highlight the difficulty of accurately predicting future technology. Ultimately, *Neuromancer* transcends mere technological prediction; its unique prose and profound exploration of the human condition remain powerfully relevant, solidifying its status as a cyberpunk bible.

The Scalability Challenge of Reinforcement Learning: Can Q-Learning Handle Long Horizons?

2025-06-15

Recent years have witnessed the scalability of many machine learning objectives, such as next-token prediction, denoising diffusion, and contrastive learning. However, reinforcement learning (RL), particularly off-policy RL based on Q-learning, faces challenges in scaling to complex, long-horizon problems. This article argues that existing Q-learning algorithms struggle with problems requiring more than 100 semantic decision steps due to accumulating bias in prediction targets. Experiments show that even with abundant data and controlled variables, standard off-policy RL algorithms fail to solve complex tasks. However, horizon reduction significantly improves scalability, suggesting the need for better algorithms that directly address the horizon problem rather than solely relying on increased data and compute.

Are All Clocks 30 Seconds Behind?

Are All Clocks 30 Seconds Behind?

The author proposes a seemingly crazy idea: all clocks are 30 seconds behind. This isn't about time zones, leap seconds, or relativity; it's about everyday clocks. Through calculation, the author shows that because most clocks only display minutes, ignoring seconds, the average error is 30 seconds. They argue that if clocks rounded instead of truncating, the average error would be 0. The author further explores how people perceive and express time at different scales (years, months, days, hours, minutes, seconds), noting that at the minute scale, intuition leans towards rounding, which conflicts with clocks' truncation. Therefore, they believe all clocks are 30 seconds slow.

President-elect Trump and Elon Musk propose eliminating Daylight Saving Time, calling it "inconvenient and costly." Nate Silver's analysis uses data to counter this, showing that abolishing DST would significantly reduce daylight hours during summer, negatively impacting schedules and health. Year-round DST, conversely, would cause very late sunrises in winter. Silver argues maintaining the status quo or allowing states to opt for year-round DST are more sensible options.

Breaking the 2GB Barrier: Asynchronous I/O for Large Files in WebAssembly

The author previously implemented setjmp in WebAssembly, bypassing WASI libc's reliance on the exception handling proposal. However, this approach was limited to files smaller than 2GB. This post details how to use the File API and Blob type to create a memory-based filesystem for handling larger files. Since web I/O is asynchronous while system languages are typically synchronous, Asyncify was used to bridge the paradigms. The author encountered optimization issues with wasm-opt, resolving them by creating a dummy wasm-opt. Finally, by cleverly using a volatile function pointer, they bypassed Asyncify's incorrect assumption about the `asyncjmp_rt_start` function, ultimately achieving asynchronous handling of large files.
