The Writers Who Wrote the Most in History

Key Points

• The author compares their own seven-month, 430,000-word blogging streak with historical prolific writers.
• G.K. Chesterton’s output and dictation-based routine are presented as a detailed example of extreme literary productivity.
• Corín Tellado is cited as another prolific writer whose weekly contract requirements drove massive output.

The Private Capture of Public Genius

Key Points

• The 1956 AT&T settlement opened 7,820 Bell patents to U.S. firms royalty-free and required reasonable licensing of future patents.
• Bell was simultaneously restricted to telecommunications, even though a later analysis found 69% of Bell patents were outside telecom.
• The article says the patent release generated nearly $6 billion in follow-on value, including substantial startup-linked innovation that fed into the semiconductor industry.

Lean Software Scaling Laws

Key Points

• The article proposes measuring coding LLM perplexity versus codebase size to estimate language-level predictability scaling laws.
• It argues that languages with stronger scaling behavior may become better targets for AI-generated and AI-maintained software.
• Lean is presented as a potential long-term winner for correctness and cybersecurity despite weaker current data advantages.

Does Code Cleanliness Affect Coding Agents?

Key Points

• The study used minimal-pair repositories to isolate the effect of code cleanliness on coding agents.
• Claude Code’s task pass rate did not change across cleaner versus messier codebases in 660 trials.
• Cleaner code reduced token consumption and file revisitation, improving agent efficiency.

Building Agents That Don't Break Themselves

Key Points

• The article separates an agent’s persistent control loop from risky shell execution.
• SpriteDoc uses isolated per-session Sprites for filesystem and command work in a multi-user setup.
• Credentials are injected only for individual commands, avoiding token storage inside the sandbox.

Egg companies made $1.22B in profit off $6 carton

Key Points

• Three major egg producers reached proposed settlements with federal and state authorities over alleged price coordination.
• The deal includes $3.3 million, 53 million donated eggs, and antitrust compliance requirements.
• Egg prices peaked in March 2025 and later fell sharply as supplies recovered and the investigation progressed.

A Forlorn Hope of Fortran Modernisation

Key Points

• The article says Fortran remains important for large-scale scientific and engineering computing.
• It identifies a shortage of Fortran programmers and weak talent-pipeline planning as major problems.
• The author argues for modernization and grounds the discussion in personal experience using FORTRAN 1977 and Fortran 90 on legacy HPC systems.

The Sneakerweb

Key Points

• Sneakerweb publishes and distributes websites without DNS, registrars, or web hosts.
• Sites are stored on user devices, browsed offline, and shared through .snk files.
• The protocol is built on Willow, which handles forgery prevention, update merging, and compact file generation.

The Age of Personalized Hardware Is Coming

Key Points

• The article argues that cheap, proliferating personal devices are creating a large new surface for custom software.
• It says AI agents will increasingly need sensor-rich, on-device execution to use physical context effectively.
• It identifies easier web-based tooling as an enabler, while embedded development complexity remains a major barrier.

Vaclav Havel, the Power of the Powerless (1978)

Key Points

• Havel argues that unchecked ideology becomes detached from reality and turns into ritualized pseudo-reality.
• He says post-totalitarian power increasingly depends on ideology for legitimacy, cohesion, and stability.
• The system persists only while people are willing to participate in what Havel describes as living within a lie.

Building relationships with customers through support didn't turn out as hoped

Key Points

• The author’s hands-on support strategy for Castro did not reliably create customer loyalty.
• Subscription pricing complaints remained negative despite explanations and extra trial offers.
• Bug reports were useful internally but often led to unsatisfying responses and limited customer goodwill.

An Ordinary Mind on an Ordinary Day

Key Points

• Kalina Christoff Hadjiilieva is highlighted for studying spontaneous thought within consciousness research.
• The article connects creativity with unstructured time through examples from Darwin, Beethoven, Dalí, and Chandler.
• Virginia Woolf and James Joyce are used to show how literature can illuminate the flow of consciousness.

Shrimple – A Simpler, Nicer Markdown

Key Points

• Shrimple is a Go-built markup tool that converts readable plain-text documents into HTML.
• The format uses footnote-based links, six-space code blocks, structured lists, and two underline-style header levels.
• It also supports note blocks and parse/render dictionaries for adding semantic highlighting without cluttering source text.

Platonic Hydrocarbons

Key Points

• Only tetrahedrane, cubane, and dodecahedrane are identified as Platonic hydrocarbons among the five Platonic solids.
• Cubane and dodecahedrane have been synthesized, while unsubstituted tetrahedrane remains hypothetical.
• Octahedrane and icosahedrane are not viable hydrocarbons because of carbon valence and structural constraints.

Modernizing a 25-year-old minimal C++ unit testing framework (Part 2)

Key Points

• The article explains how a small C++ testing framework uses macros to capture condition text, file names, and line numbers.
• It identifies per-file counters in an anonymous namespace as a limitation for multi-file projects.
• It proposes fixing the framework with C++17 inline variables and a hybrid C++20 module approach.
