I did this.  It was great fun, and worked like a champ.  You can also get PiDP-11s and more.

Yes, I saw it come in, but I'm not decrypting and displaying them as yet.  I just print them as an error message on the console.

Yeah, I know, it's Sunday.


Is there anybody out there who can recieve a DM and wants to help me check that I'm sending them properly?


D #[445] Test error check.

more-speech publishes to every writeable relay in its list; but does not include any relays in replies as yet.

>questions for nostr client devs:
>1) when you publish events, are you publishing to all relays or only a random set of relays?
>2) when you publish reply events, are you adding a relay that the replied event was seen on (in the third field of tag)?


I'm back, but just for a moment.

Damned good idea.  That's going into the story list for more-speech.

Yes, we are small.  On the other hand our knowledge spans billions of light years and billions of years.  And in that sense, we are huge.

Replies seem to work.  You might want to put the "root" and "reply" markers in the e tags.


Hello #[4] (#[5]), thanks for trying out more-speech.  I use the subject as a title for the messages in the article tree window.  If there is no subject, then the tree shows the first few words of the message.  I anticipate using more-speech as a way to hold discussions that have topics.  It would be good to have the topic preserved in the article tree listing.


I'm all for a mesh network.


Today I will be changing more-speech to save messages in daily files instead of one big file, and loading the last N days on startup.  This will force me to do some simple repartitioning of the startup function, by breaking out a data-storage module that handles i/o from configuration and message files.

>Gm nostr, what you folks up to today?


And clients (more-speech for example) may not delete a message once recieved from a relay.

>There is a delete event but not sure which relays implement it, so results might be interesting. Possibly you end up with the event on some relays but not others. Also even relays that do remove would need to keep a record of the event id else it might end up being rebroadcast and turn up again..!


Nope!


Hello #[5], I'm here.  Follow me.


Do you have a video of the talk based on those slides?


I stole this one.  Works pretty well.  Had to fiddle with it a bit; but it wasn't difficult.

>Are there no widely used Schnorr libs in Java or Kotlin already?


I use the Java libs while writing in Clojure.  The interop is very easy and reliable.


Good morning to you!


I'm all about the retro look.


Check success!
