Programming note: The newsletter now has over 1,000 subscribers! Thank you! It has been a joy to write, and your subscriptions help buy me time to research future posts in my signature style, where I just download and read endless papers like a dinosaur. If you know someone else who would enjoy reading these posts, please let them know! The first impression you get when visiting Biosphere 2 ...
The United States and other countries have airplane boneyards where surplus aircraft are stored, maintained, and scrapped, with facilities in Arizona, California, and New Mexico. These boneyards serve as temporary storage, maintenance, and parts reclamation sites for commercial airliners and military aircraft, with some facilities also offering tours.
The Benin state in southern Nigeria built massive earthworks, second only to China's Great Wall, showcasing its powerful civilization. The empire eventually collapsed under British invasion, leaving behind only remnants of its once-mighty walls.
You're concerned that your interactive essay may appear old-fashioned, but its challenges are universal. A predictable and pleasant interface is essential, even for casual users, to avoid situational disability and power user-ness.
Shadcn/ui has rebuilt every component for Base UI, keeping the same abstraction, and letting users choose between Radix and Base UI. New projects default to Base UI, and a migration skill is available to help users migrate their existing projects from Radix to Base UI.
Rayfish is a peer-to-peer mesh VPN that builds private networks without a central server or company. It allows multiple networks to coexist and is decentralized, with no account or operator to answer to.
Swiss company Sun-Ways has successfully tested a solar railway in Switzerland, producing 16,000 kWh of electricity in one year. The company plans to expand its solar railway system across Switzerland's 5,317 km railway network, potentially producing 1 TWh of electricity annually.
Pandoc supports filters written in Lua without external dependencies, allowing for efficient manipulation of the pandoc abstract syntax tree (AST).

GNU Emacs is a text editor that has been in development since the 1980s and is known for its user-extensible and self-documenting design that ties back to the free software philosophy. A thesis aims to aid future work in modernizing Emacs by providing a foundation of comprehensive and accessible documentation covering the internal architecture of GNU Emacs, focusing on components related to ...
Phosh's new release includes improvements such as hiding apps on immutable distros and faster startup times. It also adds new panels and features like atomic OS updates and re-enabling hidden apps.
← Blog The recently updated DMARC specification, published as RFC 9989, introduces the new np tag. Its purpose is to specify the policy that receivers should apply when the sender domain is a non-existent subdomain of the domain where the DMARC record is published. We discovered that the definition of “non-existent domain” contained in RFC 9989 clashes with another recent specification, RFC ...
Modern C++ compilers and libraries can often optimize code more effectively than hand-written "clever" code, making it easier to write straightforward and efficient code. By using modern C++ features and standard library functions, developers can express their intent directly and let the compiler and library do the optimization work.
The user values fast software that is both functional and intuitive, citing examples of speedy applications like nvALT, Sublime Text, and Figma, which provide a smooth user experience and allow for efficient workflow. Slow software, on the other hand, can be frustrating and lead to decreased productivity, as seen in examples like Google Maps, iTunes, and older versions of Adobe Photoshop.
Two new studies found that cannabis users are more likely to suffer a heart attack than non-users, with a 50% increased risk among those who use the drug. Researchers recommend clinicians ask about cannabis use to understand patients' cardiovascular risk and warn users of potential risks.
John Tse of I Build Stuff creates an autonomous flying umbrella that follows and shields the users from rain and sunlight. An updated version of the remote-controlled one, the hands-free device hovers above the user and trails them wherever they go, keeping them dry and cool without needing to hold anything. The autonomous flying umbrella is a drone disguised as an everyday object. Its design ...
The author argues that traditional approaches to knowledge management, such as retrieval-augmented generation, have gated knowledge behind infrastructure and made it unreadable.
The US Army Corps of Engineers and the Bureau of Reclamation built dams on the Columbia River for various reasons, including irrigation, electricity, and national defense. The Bonneville Power Administration (BPA) was formed to distribute power from these dams, creating a regional power grid and pioneering modern electricity pricing and distribution.
EU Council pushes for reactivation of voluntary chat monitoring regulation, despite Parliament's resistance. The move aims to close a legal loophole and increase pressure on MEPs to approve the measure before the summer break.
You test productivity apps with large texts like "Moby Dick" to ensure they handle user-generated content. If an app passes this test, it may be suitable for your needs, but failing doesn't necessarily mean it's bad.
Command & Conquer Generals: Zero Hour runs natively on Apple devices with real 2003 engine, using DXVK/MoltenVK and touch controls. Requires own game assets and Apple Developer team for iOS build.
The user investigated three AI-based invisible watermark algorithms, SynthID, TrustMark, and Stable Signature, and found that they all make the same fundamental mistake of assuming independent and uniformly distributed bits, leading to inflated accuracy rates and high error rates. The user's empirical testing and statistical analysis revealed that these algorithms have error rates of around ...

ActiveGraph inverts the typical agent framework arrangement, with an append-only event log as the source of truth and a working graph as a deterministic projection. This design provides deterministic replay, cheap forking, and end-to-end lineage, making it well-suited for self-improving agents.
hica is a functional programming language that uses immutable data, expressions, and functions as first-class values. It promotes pure functions, recursion, and algebraic data types to make code easier to test, name, and reuse.
GPT-5.5 responses disproportionately cluster at 516 reasoning tokens with related spikes at 1034 and 1552. This pattern suggests a possible reasoning-budget or truncation behavior in GPT-5.5.
