Now Cursor can actually see what's going on in your iOS Simulator for you 👀🤖
The new `ui-view` tool in v1.4.0 inputs image data into your conversation context automatically so you don't need drag and drop images manually into your conversation.

Know a React Native dev (~2 yrs experience) looking for a new job? A small but growing team at a mature startup in the pet health space is hiring — remote on EST, looking for someone who is excited to both teach & learn from teammates.

And last but not least: authentication!
This is perhaps the most clever: it piggy backs off the same system that domain names use.
An App View has an ID tied to a profile and then it checks to see if a domain actually has that ID, which shows proof of ownership.

Then there is Labelers and Feed Generators: servers look at the data and decide what is interesting to users!
People can do this already with feeds in the app kinda like follow lists, but people can build more sophisticated ones, such as labeling and generating feeds of entirely cat photos

Another interesting part is that if people don’t like how Bluesky, the company, does moderation or indexes the data, they can build their own.
Normally all of this data or algorithms are privately held by companies, but the AT Protocol makes it fundamentally public and remixable by other parties

![The App View is also responsible for enforcing moderation controls: for example, if one user has blocked another, and one of the users’ repositories contains a record of an interaction that should not have been allowed due to the block, then the App View drops that interaction so that nobody can see it in the client apps. This behavior is consistent with how blocking works on Twitter/X (X Help Center, [n. d.]), and it is also the reason why blocks are public records in Bluesky: every protocol-conforming App View needs to know who is blocking who in order to enforce the block (Bluesky Social PBC, 2023h; Newbold, 2023). If users are unhappy with the moderation rules applied by the App View operated by Bluesky Social PBC, it is always possible for third parties to operate alternative App Views that index the same firehose and present the data in a different way.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:n72orwuhvopahcp3xuq6oxql/bafkreidwawrg2aje3to23ekrdzrvpicfd4cimy6a3wvfrmaee5xwaj57ne@jpeg)

This data is consumed by an App View, which takes all of the data and arranges it into useful structures, like threads, profiles, and lets other service query for it.

Then there is a concept called the Relay, which indexes all the data and shoots it out in the “firehose”: a flurry of updates of user data as it happens

All of the data is hosted in user repositories.
Possibly the most interesting part of Bluesky is the fact that ALL the data is public: anyone can index it like Google does with the web.
Currently Bluesky the company does this, but users can host their own user data for cheap as well

The AT Protocol allows for multiple social networks, which they call social modes.
Functionally, it’s like how Facebook can use their own infrastructure to post multiple social media networks like Facebook and Instagram

Modern software is too large to run on individual computers, so different features like storing data, relaying that data, aggregating it into feeds and showing those feeds are broken up into individual parts

I logged back into Twitter today after giving Bluesky a test run for this last week. My notifications tab on twitter is all bots and my notifications on 🦋 are real people. I think I'll be here to stay for a while.
