The hardest working font in Manhattan (2025)

Gorton is a monoline, routing‑type sans‑serif font first supplied with George Gorton Machine Co. pantograph engravers in the early 1900s. Its square‑proportioned, mechanically uniform glyphs—flat R, wavy Q, symmetrical 6/9, and a 3 resembling Cyrillic—were designed for easy tracing and carving into metal, plastic or wood, making the lettering integral to the material rather than applied ink. The font appeared on keyboards, typewriters, industrial signage, aircraft dials, military equipment, and even Apollo spacecraft panels, persisting because engraving offered durable, low‑maintenance labeling before modern printers. Over decades Gorton’s shapes were abstracted into manual lettering sets (Leroy, Wrico), stencils, Letraset transfers, and early vector fonts (Hershey). Standardization bodies (MIL‑SPEC‑33558, ANSI Y14.2M, NATO, US National Park Service) codified the design, while various manufacturers marketed it under generic names such as “Standard,” “Universal,” or “Plain Gothic.” Its longevity stems from functional simplicity, default inclusion in routing equipment, and the legal permissibility of reproducing its letterforms.

Compression is prediction

The post explains that lossless compression and language modeling solve the same prediction problem. Modern compressors consist of three stages: transforms (pre‑processing to increase redundancy), models (probability tables for symbols, often conditioned on context), and entropy coders (e.g., arithmetic or Huffman coding) that convert probabilities into bitstreams. Better models—especially higher‑order context models—assign higher probabilities to likely symbols, lowering the average bits per symbol (Shannon entropy = –log₂ p). Arithmetic coding illustrates how a single number can encode a sequence when probabilities are accurate; Huffman coding creates variable‑length codewords based on the same principle. Large language models (LLMs) act as sophisticated, high‑order predictors: given previous tokens they output probability distributions for the next token. When used with an entropy coder, LLMs achieve compression rates comparable to state‑of‑the‑art compressors, though their massive size and compute cost make them impractical for everyday tasks like HTTP response compression. Ultimately, both compression algorithms and LLMs are governed by the same information‑theoretic objective of minimizing bits‑per‑symbol.

The discussion broadly acknowledges a link between information‑theoretic compression and predictive modeling, especially in the context of LLMs, but repeatedly stresses nuance. Participants cite historical cybernetics, entropy, Kolmogorov complexity, and practical benchmarks to illustrate connections, while others argue that compression is not identical to prediction and highlight cases where prediction fails to capture generalization, indexing, or abstraction. The consensus leans toward viewing compression as a useful intuition for LLM behavior, yet emphasizes that it is only part of a larger, more complex framework involving prediction, abstraction, and domain‑specific constraints.

The lifesaving secret hidden inside a horseshoe crab's blue blood

Horseshoe crabs, whose blue blood contains a clotting factor that detects bacterial endotoxins, have been harvested for biomedical testing of vaccines, drugs, and medical devices. In Massachusetts about 200,000 crabs are taken annually for this purpose, and the Atlantic States Marine Fisheries Commission estimates a ~15 % mortality rate from the process. The crabs also support coastal ecosystems, providing eggs for migratory birds, sharks, turtles, and fish. Eli Lilly has developed a recombinant version of the clotting protein, now used for roughly 80 % of its testing and slated for complete replacement of wild‑crab blood. Conservation measures in Massachusetts include a harvest cap introduced in 2023 and a ban on any collection from April 15 through June 7, protecting ≈90 % of the spawning period. Since the 2010 ban on harvest around full moons and recent protections, 71 % of state survey sites show population increases, though full recovery may take a decade. Neighboring states are enacting stricter bans, while Massachusetts continues to consider further restrictions on bait harvests.

The Human Is the Loop

The author paused AI usage for several weeks and returned recognizing a pattern of over‑reliance on generative agents. During the break, numerous unfinished AI‑driven tasks accumulated—multiple “cmux” tabs, paused agents, and unread Claude chats—revealing a habit of delegating routine work to bots as a coping mechanism for stress and perceived productivity pressure. The post argues that while LLM‑based agents are not chemically addictive, they foster habituation and a feedback loop where users seek to maximize tool usage rather than achieve concrete outcomes. The author notes that many personal projects built with AI lack intrinsic learning value and often do not benefit others. To counter this, a deliberate strategy is proposed: employ AI only when it adds clear value, define narrow contexts and expectations, and retain the human as the primary decision‑maker. A recent example shows AI assisting with codebase and documentation review, exposing gaps without delivering a complete solution, thereby freeing time for reflective human work. The overarching message is to keep the human “in the loop” and use agents sparingly and intentionally.
