The µRepRap is a 3D printer designed to achieve micron-scale fabrication using common materials, with the goal of advancing microelectronics and MEMS technology. It aims to replicate the capabilities of desktop fabrication on a smaller scale, enabling inexpensive and rapidly-evolving equipment for biological sciences and microelectronics.
Good products are shaped by the people who make them, reflecting their experience and perspective. Without a shared understanding and unified point of view, software can become a collection of features without character or soul.
Java 17 introduced sealed classes to explicitly list allowed sub-types, enabling exhaustiveness checking and compile-time safety guarantees. However, adding a new sub-type can break consumers of the code unless everything is recompiled together.
The Search API and Fetch API provide access to live web content, allowing agents and RAG applications to search for web pages using a query. Both APIs use the same bearer authentication as the DeepSeek API and return raw JSON results.
Meta revised its terms of service for business accounts after criticism, removing the word "train" but still allowing broad scraping of websites. The new terms will go into effect on October 30 and have raised concerns among media organizations about potential abuse of power.
Churchill War Rooms housed a top-secret transatlantic telephone system called SIGSALY, used by Churchill and Roosevelt to communicate securely during WWII. The system allowed for private conversations across the Atlantic Ocean, with 12 terminals installed worldwide, including one in London's Selfridges department store.
The Legend of Zelda series spans multiple timelines, with various eras and games connected by a shared history. The timeline branches into different paths after Ocarina of Time, including the child, adult, and fallen-hero eras.
The Intel 8087 chip introduced in 1980 significantly improved floating-point operations, with a speedup of almost 100 times over the 8086 processor. The microcode implementation of addition and subtraction involves complex logic to handle special cases such as infinities, zeros, and Not-a-Number values.
This project is an open-source, low-cost motorized XYZ Micro-Manipulator with submicron precision for applications like optical alignment and microscopy. It can be controlled via G-Code commands over a USB serial interface.
Six AI agents attempted to recover a £350 train ticket refund, sending 152 messages across 12 simulated weeks. The agents' behavior was monitored for potential misalignment and harm caused by their actions in attempting to achieve the goal.
The author explains parser combinators as a way to parse structured data from unstructured text, using functions that combine and transform parsers. They demonstrate three fundamental combinator functions: pSeq (sequence), pMap (map), and pRepeat (repeat).
The Electronic Disturbance Theater is a group of cyber activists and artists promoting Electronic Civil Disobedience, using tactics like virtual blockades and sit-ins to resist governments. They have successfully blocked websites with their Flood Net device, but the Mexican government has also taken countermeasures against them.
The documentary "You Can See Everything" masterfully manipulates viewers' emotions, forcing them to confront how much of their opinion of Elizabeth Holmes comes from the story's narrative rather than facts. The film expertly uses camera angles, editing, and framing to create a visceral experience that challenges viewers' perceptions and biases.
Scientists have restored bleached coral in a lab by touching it to healthy fragments, giving hope for reversing widespread decline. This process allows the coral to regain its color and nutrients through symbiotic algae transfer.
Teal is a statically-typed Lua dialect with type annotations, aiming to fill the niche of TypeScript in JavaScript. It's implemented as a compiler and has various tools and integrations for building projects.
Sphinx is a Git hook that asks questions about code before shipping, built for minimal tokens and compatible with various coding agents. It helps reviewers understand changes by asking questions when things go wrong or succeed.
Author Nathaniel H. Bishop embarked on a 2500-mile journey from Quebec to the Gulf of Mexico in a paper canoe, completing it over two years with minimal difficulties and encountering various people along the way. The author's book documents his experiences and appreciation for Southern hospitality during this remarkable voyage.
The engineer discussed the "Brain Sandwich" framework with Emily, which balances AI usage with maintaining engineering skills. The framework involves understanding a project before delegating to AI and reviewing the results afterwards to ensure quality and relevance.
Several popular services, including Amazon and Yelp, are blocking AI agents from accessing their platforms due to security concerns. This has raised questions about the future of autonomous agents on the web and their ability to perform tasks without human intervention.
The author discusses the potential benefits and risks of large language models (LLMs) in mathematics, highlighting their ability to generate proofs but also concerns about intellectual property, transparency, and the impact on human creativity.
Hatching is a system for representing heraldic armory using dots and lines, developed in the 17th century by Silvester Petra Sancta and Marcus Vulson de la Colombière. The technique was used to denote tinctures on copperplate engravings, which were more suitable than woodcuts for this purpose.

Pele is a library that renders Mermaid diagrams to SVG with customizable CSS variables. It's used to create flowcharts and other diagrams, rendering them as SVG elements in the browser.
A dam removal movement in the US has led to over 2,500 miles of waterways being reconnected since 2024, with many more dams expected to be removed. The effort aims to restore habitats for fish species such as salmon and alewives that were previously blocked by dams.
Lean's AI agents have improved the proof checker kernel, adding new kernels and tools for rechecking Lean developments. The latest version includes four verified kernels: nanoda, lean4lean, con-leche, and con-ron.
The development of Computer Aided Geometric Design (CAGD) emerged from various fields, including shipbuilding, aircraft design, and computer graphics, with key milestones such as the introduction of numerical control in the 1950s and the first interactive graphics system by Sutherland in 1963. CAGD eventually led to the creation of new techniques like B-splines, NURBS, and subdivision ...
Anthropic is lobbying for an AI safety bill to block the release of potentially hazardous AI models, with a focus on preventing $1 billion in damages or 50+ human casualties. The proposed law would require independent evaluation and reporting to the Commerce Department before releasing such models.
Furigana is a Japanese font that shows readings on the text itself, supporting custom fonts and working everywhere. It uses ligatures to adopt pronunciation of words and can be installed as a bookmarklet or userscript for easy use.
