Didn't know that, and that kind of sucks. it means I would have to specifically add support for each signer, and use a hard-coded URL that will go offline in the future...

Any way to verify transaction? its possible to verify that receiving address but couldn't anyone claim this zap?
Probably still better verifiability than current LN zaps because you can at least see the transaction

Built three more examples in #applesauce to test out the NIP-34 support 😀
I'm probably wasting time but its been fun to go down the list of NIPs and add support for them into applesauce. It also allows me to find edge cases can things the library cant handle well

All nsites should be hosted at the root path ( unlike github pages ) so you wont need to update the base path for vite. and if you want to change the nsite from a root site to a named site you only have to clone the event, change the kind and add a "d" tag

NIP-05 identifiers in NIP-34 nostr git URLs was a bad idea. how am I supposed to parse the URL when it requires me to make a network request. that or I now have to make my whole app consider arbitrary NIP-05 ids as valid user identifiers

Both are the same, basically just nsite: + <nsite address> + URL path

nsite are pretty decentralized. The sites metadata (file map) is stored on Nostr relays and the files are stored on the users blossom servers. So in theory this nsite is stored in 2-5 places.
Using curl -> Firefox on noStrudel or any other website / app won't work because your only downloading the html page, it's missing all the other JavaScript and CSS files

Why don't we have a bitcoin price NIP for nostr yet? wouldn't be too difficult to setup, you would just need a live replaceable even for current data and then delta events for historical. similar to what NIp-66 does but instead of tracking relays you track prices of asset A -> asset B

You don't, but I think this helps the existing users a little. at least it shows the 1 sat zaps as $0.00

Every Nostr client should support showing zaps in USD or any other currency. It's hard to describe but this feels good.

Updating the nostr-social-graph example in #applesauce to support saving and loading the graph from storage. I also took the opportunity to add a "since" filter when syncing so that apps can only look for updated contact lists.

All these examples are available in the MCP server or soon in an llms.txt on https://applesauce.build
My goal is to build lots of solid examples of common things nostr apps will need to implement, then when your vibe coding with applesauce your agent can go read working examples instead guessing how to implement something.

ah, so its talking to the device and app over serial. In that case what needed to be changed from the original Nostr Signing Device extension / protocol to get this to work?
Also if your intending this to be a first class feature of the passport prime then I would suggest we come up with a new signing protocol that isn't tied to an old ESP32 device.
I would love to have something that could work over bluetooth or USB so that (some) mobile web apps could talk to it.

Not much. the ngit cli seems to work well enough for pushing and pulling code.
The main reason I don't use it is I cant use github as the "main" remote repo and then mirror it to the grasp servers. I run into issues with branches getting out of sync and there is no easy way to force push to the grasp servers in order to reset them

Its there but I'm unsure about merging it or making it part of the blossom spec. chunked files is something blossom needs but that PR still isn't as clear or simple as id like.
Its simple enough to have a list of chunks and concat them, but the tricky part is where to store them ( relays or not ) and whether blossom servers should resolve the chunked files or if the client should resolve them.

v6.1.0 of https://jsr.io/@hzrd149/blossom-server is published. No breaking changes but it has a lot more specific HTTP status codes based on https://github.com/hzrd149/blossom/pull/98
Appreciate feedback if anyone is running it, and feedback on the PR. Id like to get stricter HTTP status codes added to the Blossom spec so we can have better interoperability between servers.

Great episode, and I love to hear what @npub1g53…drvk is working on. the hashtree stuff sounds like the second phase of blossom I've been waiting for, real chunked files and folders on blossom...

This will also help agents write clients and servers for blossom. The more I've been working with agents the more I'm realizing that trying to publish libraries and package to help them work with a spec or protocol is the wrong way.
Its better to make the protocol very explicit and detailed so they can just implement the part they need. hopefully with less code then pulling in a full library.

Taking full advantage of HTTP status codes https://github.com/hzrd149/blossom/pull/98
The idea is to define all the common HTTP status codes and how they relate to blossom endpoints. This has kind of been an unspoken rule for too long that clients and servers should follow HTTP but its much better to actually define it in the blossom spec.
#asknostr I would appropriate lots of feedback on this since its a big change. although its not a breaking change

yeah, the site itself is an encrypted site.7z file. the wrapper site just serves as a way to decrypt the file and then put it in local storage so it can be served

This is probably a better idea, having ctrl+c close the app isn't great for the world of TUI's

They are saved, but its really annoying to start opencode again and try to remember what sessions where in the middle of work. then I have to tell the agent to "continue work"

#asknostr how can I prevent ctrl+c closing my opencode editor? I've lost too many coding sessions by accidentally pressing it
