The article presents a theory of 'groupcore', which suggests that social groups form around a core set of beliefs, values, and traits that define the group's identity and bind its members together. The author argues that understanding groupcore can provide insights into group dynamics, conflict, and cohesion.

Hi HN folks,

Deep here. I am a design engineer and I have been building Resurf for the past 4 months. Resurf is a local first Mac app for quickly capturing notes, thoughts, ideas, inspiration, links, and files like PDFs and images without switching context.

As a design engineer who cares a lot about craft, I built resurf because my “stuff I want to keep” was scattered across tabs, different apps, notes, screenshots, random folders, and I kept losing good references. A lot of tools exist, but I wanted something calm + polished that feels native on Mac (not another file manager).

with Resurf you can

- quickly capture with a global shortcut and a menu bar app - capture notes, links, and media like images, videos, and PDFs - save things without switching windows and breaking your flow - lightweight organization with Inbox to spaces, tags, and notes so you can categorize later - search across everything including keywords, type, tags, dates, and spaces - spotlight style quick panel to find anything fast - keep everything local on your file system with no cloud account

It also has an in-app web view and PDF viewer so you do not need to open multiple browser tabs.

we are still working on optional AI features (BYOK) to make this more powerful for people who wants AI.

The app is usable today but still beta. I am fixing bugs quickly as people report them. I am also exploring the best way to add AI and the resurfacing part based on early user feedback.

Would love to know what you think and any special use case you have.

The article discusses four modes of AI-augmented technical writing: automation, enhancement, generation, and optimization. It explores how AI can assist writers in tasks like document creation, editing, content generation, and improving writing quality and efficiency.

Sir Mark Tully, a renowned BBC reporter who spent over 30 years covering news in India, has passed away at the age of 86. He was highly respected in India for his deep understanding of the country and his ability to accurately report on its complex issues.

The article discusses an opinion by an advisor to the European Union's highest court, which supports the neutrality of VPNs in a copyright case involving the Anne Frank Foundation. The opinion argues that VPNs should not be held responsible for copyright infringement committed by their users, as they are neutral technology providers.

Hello HN! I'm a long time lurker. It's only now that I've decided to sign up, when I read a comment by nick_m: https://news.ycombinator.com/item?id=46511892

I'd like to help Nick (and have some fun reverse engineering), alas I've got no means of reaching out to them. Nick, if you're reading this, please leave some contact info. I figure it's a long shot, but... why not try?

Hopefully this submission is within the rules.

The Vortex project is an open-source implementation of the WebXR specification, aimed at providing a cross-platform, highly performant, and feature-rich WebXR runtime. It focuses on enabling developers to create immersive web-based experiences across a wide range of devices and platforms.

The article discusses the progress made by OpenAI's language models, including their ability to perform various tasks like document summarization, sentiment analysis, and question answering. It highlights the potential for these models to be deployed as assistants across different domains.

The article discusses the Tick Cache, an open-source cache system designed to handle high-volume time-series data. It provides an overview of the Tick Cache's architecture, performance characteristics, and use cases, making it a valuable resource for developers working with time-series data.

I built Humynize because I realized that even with the best prompts, AI drafts still feel mechanical. I found myself spending hours fixing the "flow" rather than the content.

I used Next.js for the frontend and OpenAI for the core processing. The logic focuses on NLP structural re-architecture—essentially breaking down the robotic patterns in the sentence structure and restoring a human-like "burstiness" and rhythm.

Key Technical Focus:

Technical Integrity: It is designed to keep data, citations, and specific meaning 100% intact while changing the voice.

Structural Variety: It moves away from the predictable sentence lengths that AI detectors look for.

Speed: Using a clean stack for fast processing and high-precision output.

I am the founder, and I would love for this community to test it. I am specifically interested in feedback regarding the quality of the "Human-Voice Shield" and how it handles technical or academic text.

I am around to answer any questions about the build

Researchers have discovered a new method to produce graphene using amino acids as a precursor, which could lead to more cost-effective and sustainable production of the material. The study suggests that this process can be a more environmentally friendly alternative to current graphene manufacturing techniques.

The article discusses the concept of strictly monotonic time, which is a property of clocks where the time values are always increasing and never decreasing. It explores the importance of strictly monotonic time in software development, particularly in the context of event-ordering, concurrency, and distributed systems.

Ikejime is a traditional Japanese method of killing fish that minimizes stress and preserves the quality of the meat. The process involves precisely cutting specific nerves to quickly render the fish unconscious and dead, resulting in a fresher, higher-quality product.

LLMNet is an open-source library for building and deploying large language models (LLMs) using PyTorch. It provides a modular and extensible framework for training, fine-tuning, and evaluating LLMs, allowing developers to quickly experiment with different model architectures and techniques.

Iran has implemented a new policy that limits internet access for traders to 20 minutes per day under supervision, as part of the government's ongoing efforts to restrict digital connectivity and control information flow in the country.
