Hey, I’m looking for work!
Have you got a big new Nostr-related idea for an app or feature that you need help developing? I’d be more than happy to lend my skills to your ideas
I’m a dev with a strong background in full-stack web, native iOS/desktop app development, and systems programming whose fallen down the Nostr rabbit hole since Nostrica and am happy to take calls to hear about your project :)
Here’s my development portfolio 👇🏻

Help me out by boosting or sending this note around to people who should see it! pv

What are you using behind the scenes for websocket management?

Yeah, quite some progress! I’m preparing a full client dedicated to private DMs. It will ship originally with regular NIP-04 support, and my plan is to support a range of extensions and alternatives. There is no shortage of interesting ideas to improve DMs on Nostr, incognito DMs being pretty good. What we need now is just a client or set of clients that act as a testing ground for these ideas: bring real users to stress test the different ideas and find what works and what doesn’t.
My current thoughts on Incognito DMs/wrapped DMs is that I think the wrapped private events are a great idea that will likely be a core part of whatever the final system is, so that’s staying. But I’m not entirely sure about disposable identities/ephemeral pubkeys anymore. They are very simple conceptually, but they don’t play well with relays. Relays want real pubkeys, they want to know things are not spam. So I think the idea needs more work, but generally I’m optimistic that we can definitely find some system that both works with relays and preserves privacy.

Oh wow I tapped the “Post” button in the thread view multiple times thinking it didn’t work, but apparently it did but the notes showed up later. And once they did finally show up the next message I was typing got cleared. Maybe the input/post button needs to be disabled while you’re sending a note?

Yeah, on this note, first JSON decoding of multiple events can be trivially parallelized and second the rapidjson C++ lib is incredibly fast.
Finally, the biggest performance hit with this type of work is the heap allocator being used to allocate new memory for each object being decoded.
If you pre-allocate a bunch of space for the decoder output and use a format like rapidjson where the entire result uses one contiguous memory region it’ll be blazing fast without any need to make architectural changes to the protocol.

nostr-pow: A little npm Node module for finding Nostr event nonces.
On my Mac mini 3.2GHz 6-Core i7 I’m getting about 10 megahashes/second. Curious to see what others are getting 🤔

BitTorrent gets a whole bunch of things right, but it’s core fault (which I think is just an unfortunate case of its design predating cryptocurrencies) is that it doesn’t distinguish people who want to consume from people who want to provide.
This is something that Nostr gets right, and why it’s got a better chance of scaling vs scuttlebutt. There are people who run relays and there are people who use clients. And it’s possible economically because relay operators can charge for the service they provide.
For the BitTorrent network to be healthy users must try to balance what they take from the network by giving back to the network. This is hardly ever the case, so you end up with leeches on one side ruining the network, and lawful users who suffer for their good will.
If you can incorporate a currency to bridge the gap between consumers and providers you have yourself a much healthier system.

Incognito DMs, let’s go!
After a week of back and forth between #[0] and I we have fine-tuned and finished a first draft for NIP-32 incognito DMs.
I have created a PR for the NIP to open up our idea to discussion and feedback. We will be publishing a reference client implementation for the NIP later this week, forked from #[1] ’s Hamstr client.

This sounds very promising! Where does your client host the content?

Is there anything in particular I should do to reproduce this? Is it when scrolling? DMing? Any insights you have could help get the ball rolling

For the moment I’ve left the Mention object intact and have added a MentionBech32 that represents all the different Bech32 entities, but it might be easier to turn all inline mentions into Mention blocks without an index for now. Depends on how you feel about it. Don’t want to add too much complexity to your codebase :)

Haha, one reason is to make it optional when you mention someone if you want it to notify the person or not. Clients can decide whether they place mentions into the tags field or if they leave them inline. And particularly for DMs to avoid the mentions being leaked to the public they should stay inline

Yes, we considered this, but to derive keys from your private key would require direct access to your key which isn’t supported through window.nostr and would require support from signing devices. Not impossible but a little harder.
And further more, if you never send invites it’ll be harder for clients to find open conversations. You’ll have to query a bunch of keys of people you follow to find conversations. So each variant comes with its own set of compromises

Like Vitor suggested, it could help for the wrapped DMs to use a different kind so the relays are able to treat them differently from regular DMs, and optimise accordingly.

Is this filtering happening on the client level? If so could the client accept DMs from unconnected pubkeys provided they contain a signed invite from someone in your network?

What’s the Nostr build API for uploading video? You make a PUT request with the video file?

Here’s a video demo of “Incognito Direct Messages” - showing a forked version of Hamstr that can send private NIP-04 DMs where no metadata is leaked to the public (no more inbox peeking).
#[0] #[1] and myself developed this as part of the Nostr Hackathon organised by Hard Yaka, Universal Names and #[2].
The main idea was developed by Anton and #[3] (developer of Hamstr.to). The essential idea is to create new disposable identities for each conversation you create, you exchange these identities with your peer secretly, and then the entire conversation takes place away from your public identity. It’s very simple, it works, there are some weaknesses (you have to trust relays), but it’s a step in the right direction.

#[0] #[1] Question about transport in Uvita: I’m arranging transport during my stay for Nostrica. Is a fourwheel drive recommended during this season to drive around in Uvita? Or will a regular car be fine? Thanks!

Agreed, but nostr still has everything to prove and much to be figured out. Once the real traffic arrives, bots and all, it will be interesting to see how _and if_ nostr will be able to handle that….without enduring the same fate as email
