Anysphere, home for important, long-form conversations
Hi everyone! I’m Arvid, cofounder of Anysphere (https://anysphere.co). With my two friends Sualeh and Shengtong I have been spending the last few months building a dedicated home for important, long-form conversations. We’re super excited to let the HN community test it out! We think that no existing platform for point–to-point communication prioritizes the conversations that you actually care about and that really matter. Instant messaging is filled with careless texts and stickers, email is filled with receipts and spammers, and physical mail, while better in those respects, is…
In plain words
Anysphere is a desktop-first messaging platform designed for meaningful, long-form conversations between individuals. It prioritizes privacy and security by allowing only pre-approved contacts to reach users, avoiding the clutter of instant messaging and email spam. The platform positions itself as an alternative to existing communication tools by focusing exclusively on important exchanges rather than casual communication.

Hi everyone! I’m Arvid, cofounder of Anysphere (https://anysphere.co). With my two friends Sualeh and Shengtong I have been spending the last few months building a dedicated home for important, long-form conversations. We’re super excited to let the HN community test it out! We think that no existing platform for point–to-point communication prioritizes the conversations that you actually care about and that really matter. Instant messaging is filled with careless texts and stickers, email is filled with receipts and spammers, and physical mail, while better in those respects, is slow and cumbersome. None of the existing platforms are private enough. Anysphere attempts to fix this. It is private, secure, desktop-first and only allows people you added to contact you. Our whitepaper (https://anysphere.co/anysphere-whitepaper.pdf) describes our privacy and security model in detail — in short, we protect all of your data and metadata against everyone (even our own server). Our client is fully open source: https://github.com/anysphere/client. We deployed a small server to open up testing to everyone in the HN community. Instructions are here: https://gist.github.com/arvid220u/d960ca6483bf5f295498d9de99.... I can’t wait to hear your thoughts!

Hi HN, I built Eigendrum, a web tool that solves the 2D wave equation for arbitrary shapes so you can hear what they sound like as drums. How it works: * Solves -∇²u = λu using finite element analysis (Kφ = λMφ) on a triangle mesh. * Validated to <0.1% error against closed-form solutions for circles (Bessel zeros) and rectangles. * Sound model factors in strike location, Rayleigh damping, and mallet width. * Includes Kac drums I & II to demonstrate identical sound spectra from different geometries. * No frameworks, build steps, or dependencies. Repo and tests:…

Hey HN, I've been working on https://pornpen.ai, a site for generating adult images. Please only visit the site if you are 18+ and willing to look at NSFW images. This site is an experiment using newer text-to-image models. I explicitly removed the ability to specify custom text to avoid harmful imagery from being generated. New tags will be added once the prompt-engineering algorithm is fine-tuned further. If the servers are overloaded, take a look at the feed and search pages to look through past results.
