The WisdPi 10G Ethernet Expansion Card for Framework computers has performance issues due to USB-C bandwidth complexity and Realtek RTL8159 Ethernet controller limitations. It can reach up to 9.4 Gbps speeds on Windows 11 but may overheat and is not recommended for laptop use.
The user built hackmyclaw.com to test OpenClaw's security, sending over 6,000 emails to try and leak a secrets.env file, but none were successful. The experiment showed that prompt injection is harder than expected, even with sophisticated attacks, and the user is now more optimistic about AI security.
Australia's under-16 social media ban is not working as intended, with 7 out of 10 kids still using social media. The law mandates age verification through biometric info, government IDs, or other data, introducing new risks for data breaches and phishing attempts.
A recent paper by five authors shows that the Bipartite Matching problem is in the complexity class NC, resolving a central problem in parallel algorithms and derandomization that's been open since the 1980s. The result has sparked discussions on the implications of the paper and the potential for derandomization in other problems, with some users highlighting the importance of regulation in ...
A 248-year-old notebook in France's National Library has been identified as belonging to 22-year-old Mozart, containing daily exercises and 7 pieces for flute and harp. The notebook was confiscated during the French Revolution and has now been authenticated as a major discovery in music history.

IBM unveiled a sub-1 nanometer chip technology with a revolutionary transistor architecture at the 0.7 nm node, nearly doubling transistor density. The breakthrough offers up to 50% more performance and 70% greater energy efficiency, enabling future advancements in computing and AI.
Researchers have developed microbubbles to deliver drugs to the body, overcoming barriers like the blood-brain barrier. Microbubbles can be steered and burst on command, temporarily opening biological barriers to allow treatments to pass through.
Remember the dot prompt? Before SQL won, before ORMs, before anyone said "full-stack" — there was dBASE III. You typed USE customers, then LIST, and your data was just there. WebBase-III brings that whole world back: the terminal, the language, BROWSE, @ SAY GET forms, .prg programs, indexes, reports — rebuilt from scratch as a modern web app with its own interpreter in TypeScript, ...
OpenKnowledge is a local markdown editor with integrations for LLMs, available as a desktop app or local web app via CLI. It supports macOS, Linux, and Intel Macs, with Node.js 24+ required for installation.
Researchers at Unconventional AI built Un-0, an image generator powered by a simulated system of coupled oscillators, achieving FID 6.74 on ImageNet 64×64, matching the quality of leading conventional image generation methods. Un-0's architecture harnesses the laws of physics to do the computing, aiming to run modern AI on a fraction of the energy today's machines need, around 1,000x less.
A seeded chess-pathfinding roguelite. Guide Prince Chazz across the board, dodging enemy pieces, and race the per-seed leaderboard.
You accuse Nico of copying code from Papermark's open source and enterprise-licensed code without permission, demanding the product be taken down immediately. This action is seen as fraudulent and reflects poorly on Nico's business and the YC community.
The author describes Bank Python, a proprietary fork of the Python ecosystem used by investment banks, which includes a global database called Barbara, a job runner called Walpole, and a data management system called MnTable. The system is designed to be holistic and all-encompassing, with a focus on data-first development and a unique approach to software engineering that differs from ...

The Zig compiler has made several improvements in 2026, including a new ELF linker with fast incremental compilation, improved LLVM backend, and enhanced build system. These changes aim to improve performance, usability, and stability, with features like incremental compilation, lazy type analysis, and better error messages.
A restaurant replaced physical menus with a QR code, causing inconvenience and chaos among a group of six people. This experience illustrates the Doorman's Fallacy, where technology replaces humans without considering the consequences on customer experience.
The user is writing a series of posts on type inference for anonymous records, a feature that is still lacking in many statically typed languages. They are explaining the basics of type theory and introducing a notation for type inference rules to make the concept more accessible to readers.
A paper called More Fun with Monoids by Oleg Kiselyov introduced a map-reduce pattern that can be used to solve the parentheses matching problem with O(n) work and O(logn) span. The problem can be further parallelized using a previous or smaller element problem algorithm to solve the general definition of the parentheses matching problem with O(nlogn) work and O(logn) span.
The Roman identity has evolved over 1500 years, with various groups in Europe and beyond claiming Roman heritage. These groups include Romanians, Romansh people in Switzerland, Romeika speakers in Greece, and others who have maintained their connection to the Roman Empire.
