THE INTERNET IS THINKING
Earlier sources: Open source software
Open source software makes source code available under licenses that grant specified rights to use, modify, and share it. Follow public projects and releases; availability, maintenance, and license terms should be checked in each repository.
SYMTRI organizes observations from public sources into a living map. Connections reflect shared subject matter; they do not establish causation or endorse a source.
Open in the map ↗384 classified signals in the fourteen-day window. These counts include signals awaiting readable evidence.
Earlier sources
Up to ten sources with readable evidence, ordered by their feed timestamp. These archive sources can be older than the live fourteen-day window. This list is a sample, not a measure of total activity. Dates distinguish paper publication, repository creation, model/dataset activity, Hacker News posts, and KEV catalog additions. “First archived” records when SYMTRI first stored the signal.

Show HN: Open-source iPhone app that streams Claude like the Siri app ↗
I spent the past year building Swift Chat, a Swift package that recreates iMessage exactly. This week, I added an assistant style for AI apps. Exactly like the new Siri app, the question bubble animates into the top of the screen, and then the agent's response streams underneath in Markdown. Starter app is about 300 lines and MIT licensed. It streams Claude over server-sent events with URLSession, handles photo input, keeps the API keys, and stor…

How to assess evidence about Open source software
Check each original source for its methods, release status, limitations, and supporting data. A repository announcement, a preprint, and a published study provide different kinds of evidence. SYMTRI’s subject classification helps discovery; it does not independently validate the source’s claims.
