Hey👋

I have a goal to write a blog post every month this year. I’m going to use this 🧵 to link all the ones I’ve written so far and future ones.

Bailey Townsend 🦀 @baileytownsend.dev · Nov 24

Welcome to my mega 🧵 on getting started with Rust on the RP2040! This thread aims to get you started with writing Rust on the Raspberry Pi Pico. The actual end result will just be a blinking on-board LED. It’s up to YOU to take this foundation and make awesome projects from it.

Workspace featuring various Raspberry Pi boards, including a Raspberry Pi Pico on a breadboard, two Pico W boards, and a Raspberry Pi Debug Probe in its case. A Pimoroni Badger 2040 W e-ink display shows developer information and Wi-Fi details in the background. Electronics components are neatly arranged on a wooden desk, with cables and packaging nearby.

Then always have old faithful of just following along to what happens on the createRecord endpoint on the PDS and see it in code

May have to think on this one a bit and may need a definition on a design researcher 😅. Sorry for being a bit dense on that one, might also just need another coffee

Bailey Townsend 🦀 @baileytownsend.dev · 1h

Thank you! Means a lot to read this and I'm glad I'm able to help out!

Bailey Townsend 🦀 @baileytownsend.dev · 1h

PDSls also checks out on trying to resolve it cause of CORS issues so may want to make sure that is set right. I don't think the AppView would follow that, but never know

dug a bit more cause it's an interesting one that's for sure. That "Profile not found" not found from your PDS is a proxy to the AppView request. The AppView is having a hard time resolving your did doc I think.

I haven’t messed with did:webs yet for accounts but this may be a good read over as well.

I think i'll have to research it a bit more. But I think there may be a bit of overlap going on with the handle and did:web being the same if I'm reading it right. May try using different ones for each like maybe did:web:yeehaw.bront.rodeo as the did web and use atproto.bront.rodeo as the handle

I'm not sure if relay's are finding PDSs on their own. But can call this XRPC endpoint on a relay to add it to the crawl list. So I think as long as that gets passed along to a Bluesky controlled relay it all passes between them

docs.bsky.app/docs/api/com...

com.atproto.sync.requestCrawl | Bluesky

This endpoint is part of the atproto repository synchronization APIs. Requests usually do not require authentication, and can be made to PDS instances or Relay instances.*

Bailey Townsend 🦀 @baileytownsend.dev · 2h

The relay's subscribe to the PDS. So a atproto action happens on the PDS, the PDS sends it on a websocket, Relay picks it up and sends it back out if i'm not mistaken. A bit of a fan out thing, many PDSs to a relay so AppViews don't sub scribe to each PDS

I think with proper lay out and using S3 for blobs you can hit the thousands of users for about $50 a month on a VPS

Bailey Townsend 🦀 @baileytownsend.dev · 3h

A few here and there. From personal experience my first PDS ran well on the $6 a month Digital Ocean droplet

Selfhosted.social sitting at 16 active accounts is $23ish a month ($14 2g ram droplet, $4.20 for nightly backups, $5 for S3 bucket for blobs). Should be able to handle a few hundred users

Bailey Townsend 🦀 @baileytownsend.dev · 3h

it's so tempting. been on the back of mind my all week lol. so many other things to do atm

Bailey Townsend 🦀 @baileytownsend.dev · 3h

I may be a bit slower getting to answers with this AMAA, but will check in during the day and answer them as I have free time.

Bailey Townsend 🦀 @baileytownsend.dev · 3h

I'm doing an AMAA, ask me anything atproto, for the rest of the day. Got a question you've always wondered about ATProtocol and the atmosphere? Ask below and I will do my best to answer or at least point you in the right direction! As always there's no dumb questions, we all started somewhere.

Some other things is.

- Be nice to have it’s own upvote button as a universal like to know what’s popular

- combine with things like leaflet comments to know if a post is popular

Bailey Townsend 🦀 @baileytownsend.dev · 4h

Been thinking on it lately. The idea is pretty much a feed of all the popular lexicon types. A link aggregator of popular things on the atmosphere and take into account what’s popular with your friends.

The goal is each post has a custom ui for that lexicon and invite the creators to design them

Bailey Townsend 🦀 @baileytownsend.dev · 6d

I need a morning newspaper AppView.

Show me the previous days top bsky posts, tangled repos, played songs, leaflets, books marked reading, TV shows, and so on from my neighborhood of the atmosphere

It hit me once I came back to the post to make sure I read it right and realized it was an og:image haha. Looking good!

Bailey Townsend 🦀 @baileytownsend.dev · 4h

Not me clicking on the repo to see what that repo had to do with generating og:images 😳

dropped an example here too if you need it

Bailey Townsend 🦀 @baileytownsend.dev · 4h

Yeah! So can call the /xrpc/com.atproto.sync.listReposByCollection on a relay and it gives you a list of DIDs with that collection. So then know which repos you need to get the records from. Here's an example with a teal.fm record
