Why does this still come up?

What do you mean? The url is always part of the post.

The extra hashtags?

It will be there. It helps with previews and to make sure server doesn't modify the image after the author has approved.

Bonjour Vitor en fait je me permets de vous faire remonter que la plupart des clients Damus ont un soucis de traduction pour les notes surtout en français.. Travaillez vous ensemble ? Puisque certains utilisateurs passent à côté de certaines qu'ils peuvent traduire.. Lorsqu'on me le signale je traduis mais quand même c'est plus prioritaire dans les interactions sociales j'imagine certains qui ne lisent pas de notes car bloquent au niveau traduction'.. Au niveau Amethyst il n'y a pas de soucis peut-être nostr:npub1xtscya34g58tk0z605fvr788k263gsu6cy9x0mhnm87echrgufzsevkk5s devrait interroger les utilisateurs.., il m'arrive de traduire régulièrement entre pairs

Thanks man! I think most ppl who have used variety of nostr clients can agree that amethyst has the best user experience.

Do any other clients support this, or are you first again? 🚀

Only us for now. But Gossip, Coracle and 0xChat are working on it.

I didn't understand the new nip-44 feature.

What advantages does it have?

Avatar
Vitor Pamplona 2y ago

It's just an encryption upgrade for DMs. It's now audited.

"Encryption, because it's audited" is like "Brawndo, it's got electrolytes"

Do you have a link to the diff of v2?

Avatar
Vitor Pamplona 2y ago

People want to forget v1 existed so there is no good doc to show. But essentially, v2 fixed some issues with message length (smaller messages would yield smaller encrypted bytes, which is not ideal). We also got rid XChaCha because it is not standardized and the added protections aren't needed inside Nostr messages.

v1: XChaCha20 with sha256(parity + ecdh) as a shared key per conversation

v2: secp256k1 ECDH, HKDF, padding, ChaCha20, HMAC-SHA256, base64

v1: https://github.com/coracle-social/nips/blob/7f98a7b8849c16f9d324e0ea15db4efda0ee84fb/44.md

v2: https://github.com/nostr-protocol/nips/blob/master/44.md

Thanks!!

What happens if a NIP44 (v1 or v2) message gets sent to a legacy NIP4 receiver? Does that client handle it?

Avatar
Vitor Pamplona 2y ago

No. The encryption is not backwards compatible so each other client will have to decide to support it or not.

Avatar
Max 2y ago

And this replaces the giftwraps which were previously implemented in Amethyst Incognito DMs?

Avatar
Max 2y ago

Ah, giftwraps is NIP24, and that's still there in the latest Amethyst.

So, what's the new thing for DMs?

Avatar
Vitor Pamplona 2y ago

Nip44 is used by GiftWraps, which is used by nip 24. :)

Max 2y ago

Of course, that makes sense!

How are you checking the MIME type by pinging the server?

Avatar
Vitor Pamplona 2y ago

I check for opengraph's info for preview cards in every url. Thus, I end up hitting the server even for images and videos. When that happens, you also receive the content-type of the file in the HTTP header. I use that to determine how to render the media.

I still check extensions first, but that has proven to be problematic (some image servers serve different formats, other urls have query params that affect the discovery and many don't actually offer extensions at all).

Matt Lorentz 2y ago

Cool. I wasnt sure if there was another trick besides OpenGraph. Thats what we use in Nos, but it’s slow and causes the cells to change size which makes scrolling less comfortable.

Avatar
Vitor Pamplona 2y ago

The only way to trully solve this is to either have a server that can provide image sizes or download everything before showing on the feed. There are hacks like the imeta tag or nip54, but those depend entirely in the writer client including them, which is not ideal for the receiving client.

Scrolling seems to be quite a bit smoother after this update. 🤘

nostr:npub1gcxzte5zlkncx26j68ez60fzkvtkm9e0vrwdcvsjakxf9mu9qewqlfnj5z I love the statistics chart in the notification section, could we also see the amount of sats sent through zaps? And maybe also having the possibility to look a 2/4 weeks chart time? 💜🫂🍀
