Show HN: Fluffy Sparrow – Frictionless, Fast, Note Taking App

Fluffy Sparrow is a frictionless, fast note-taking app developed over two years, prioritizing speed and simplicity. It supports quick one-liner notes, to-do lists, tags, inline calculations, filtering, and search, with all data stored in plain text. The app is available for a one-time payment of $15, with a discounted $10 price for the first 50 purchases.

Background

- This is a "Show HN" post — a common tradition on Hacker News (HN, a tech-news site run by Y Combinator) where developers share side projects for feedback. The audience is technically sophisticated and skeptical of over-engineered tools. - The creator spent two years building Fluffy Sparrow, a note-taking desktop app focused on speed and simplicity. Storing notes as plain text files (not a proprietary database) means they can be searched or processed with standard Unix command-line tools like `grep`, a major selling point for developers. - "Vibe coded" is recent HN slang for apps quickly thrown together using AI code generators (e.g., ChatGPT or Claude). The creator explicitly distances the app from that trend, positioning it as carefully handcrafted. - The app costs $15 (one-time, no subscription). The "first 50 purchases for $10" discount and the fully functional demo (with the caveat that it can't save files) are typical HN launch tactics. - "Moby Dick workout" refers to stress-testing the app by loading the full text of Herman Melville's novel — roughly 200,000+ words — to demonstrate it stays responsive.

Max Weinbach says he had early access to OpenAI's new model GPT-5.6 Sol, calling it his favorite model by far. He highlights that it never gives up and will keep reasoning until it's done. OpenAI announced that GPT-5.6 Sol, along with Terra and Luna, will launch publicly on Thursday, with preview access expanding globally now.
Statement on the US government directive to suspend access to Fable 5 and Mythos 5

The US government ordered Anthropic to suspend access to its Fable 5 and Mythos 5 models for all customers, citing a potential jailbreak technique that involved asking the model to review a codebase for vulnerabilities—a capability Anthropic says is available in other public models. Access was abruptly cut off on June 12.

Andrej Karpathy announces the release of Claude Fable 5, the same underlying model as Mythos but with added safeguards. He calls it a major step forward, particularly for long problem-solving sessions on difficult tasks, and describes it as state-of-the-art on nearly all benchmarks with exceptional performance in software engineering, research, and vision.

Roman Storm warns that the legal theory in his case could set a precedent making open-source developers liable for how others use their code, potentially criminalizing the mere publication of privacy, messaging, or crypto tools. He notes that developer Michael Lewellen cannot publish lawful code due to prosecution fears, and argues this chilling effect extends beyond any single case.
‘Why Is Meta Destroying Its Engineering Organization?’

Meta's engineering culture is deteriorating under Mark Zuckerberg and Scale AI CEO Alexandr Wang, who have introduced keyboard tracking, reassignments to data labeling, and AI-centric performance metrics. Critics argue this incentivizes performative AI use, drives away experienced engineers, and contributed to a major Instagram hijacking incident caused by AI-written and AI-reviewed code.
