Banning Billboards: A Simple Fix for Urban Aesthetics

2025-04-07

City improvements often require vast sums and years of planning. However, one simple change could dramatically improve urban aesthetics: banning billboards. While city design review boards meticulously scrutinize building designs, massive, visually intrusive advertisements escape this oversight. These billboards, often placed in highly visible locations, detract from the peacefulness of the urban environment. The author argues that banning them would benefit the vast majority, with only a few billboard-owning landowners opposing the change.

Trimethylaminuria (TMAU): The 'Fish Odor Syndrome'

Trimethylaminuria (TMAU), or 'fish odor syndrome', is a rare metabolic disorder causing sufferers to emit a strong fishy odor. More common in women, it's linked to FMO3 gene mutations hindering the breakdown of trimethylamine. This chemical builds up and is released through sweat, urine, and breath. While not life-threatening, TMAU significantly impacts quality of life. Treatment focuses on managing symptoms through diet modification (avoiding trimethylamine-rich foods), hygiene practices, stress reduction, and sometimes antibiotics or activated charcoal. There's currently no cure.

Musk's Self-Driving Scam: A Decade of Promises, a Mountain of Lies

This article exposes Elon Musk's decade-long deception regarding Tesla's Full Self-Driving (FSD) technology. Since 2015, Musk has repeatedly promised the imminent arrival of FSD, yet it remains undelivered. The article highlights Tesla's inferior 'vision-only' approach compared to Google's Waymo, which operates driverless taxi services in multiple cities. Musk's rejection of lidar technology has resulted in more Tesla accidents. The upcoming Robotaxi launch in Austin is also revealed as not truly driverless, relying on remote human supervision. The article critiques Musk's arrogance and incompetence, and the misuse of technology by tech giants and its impact on society.

The Bitter Lesson Strikes Tokenization: A New Era for LLMs?

The Bitter Lesson Strikes Tokenization: A New Era for LLMs?

This post delves into the pervasive 'tokenization' problem in large language models (LLMs) and explores potential solutions. Traditional tokenization methods like Byte-Pair Encoding (BPE), while effective in compressing vocabularies, limit model expressiveness and cause various downstream issues. The article analyzes various architectures attempting to bypass tokenization, including ByT5, MambaByte, and Hourglass Transformers, focusing on the recently emerged Byte Latent Transformer (BLT). BLT dynamically partitions byte sequences, combining local encoders and a global transformer to achieve better performance and scalability than traditional models in compute-constrained settings, particularly excelling in character-level tasks. While BLT faces challenges, this research points towards a new direction for LLM development, potentially ushering in an era free from tokenization.

Stasi's 'Zersetzung': How East German Activists Resisted Repression

This article explores the experiences of East German political activists who faced Stasi informants and infiltration before the fall of the Berlin Wall. The Stasi's invasive spying and disorienting tactics severely limited possibilities for civil disobedience. Despite this, activists sparked a grassroots revolution in 1989. Based on interviews, the article reveals the Stasi's 'Zersetzung' (corrosion) strategy: creating conflict, sabotaging activities, and isolating groups to weaken opposition. Activists resisted through support networks, inter-group solidarity, open actions, and careful investigation of potential informants. Their resilience highlights the human cost of repression and the unexpected success of grassroots movements even under extreme surveillance.

Why I Prefer reStructuredText to Markdown

This post details why the author prefers reStructuredText (rST) over Markdown for writing technical books. rST, being a mid-weight representation of an abstract documentation tree, offers superior extensibility and customization compared to Markdown's lightweight approach. The author illustrates this with examples of image creation and exercise handling, showing how rST's custom directives and document tree transformations enable complex document structures and functionalities difficult to achieve in Markdown. While acknowledging rST's potentially less intuitive syntax, the author champions its power for large-scale documentation, especially when custom extensions and transformations are needed, as demonstrated in his book, "Logic for Programmers."

ALMA Reveals Most Protoplanetary Disks Are Surprisingly Small

2025-04-05

A high-resolution ALMA survey of the Lupus star-forming region has overturned our understanding of protoplanetary disks. The study reveals that most disks are far smaller than previously thought, some even smaller than Earth's orbit, and lack the large-scale gaps and rings previously associated with planet formation. This suggests that many stellar systems may favor the formation of super-Earths rather than gas giants, consistent with previous exoplanet observations. The research highlights observational bias in astronomy and reveals much remains unknown about planet formation.

The Federal Communications Commission (FCC) has rejected proposals to impose cable-style regulatory fees on streaming services, tech companies, and broadband providers. Groups like the NAB argued that these companies benefit from FCC resources and should contribute financially. However, the FCC cited administrative difficulties and a lack of evidence showing increased regulatory burdens imposed by tech firms. Telecommunications and tech trade groups opposed the proposals, arguing fees should only cover directly regulated industries. The FCC's decision maintains the existing fee structure, with broadcasters, satellite operators, and licensees bearing the burden through fiscal year 2025.
