Not only that, but spending it becomes a price stabilization mechanism, and arguably helps make it even more decentralized.

I have just pushed some major updates to @npub1nzr…36v5
- Dedicated accounts for #airports. You can now follow an account and only see posts for that specific airport.
- Updated #airport #delay information will now be posted as a reply to the original post.
- Certain airport #closures will now be posted.
- Finally for the #datascientist experts out there. I have released a complete dataset of raw #FAA XML data on Hugging Face that #AirportStatusBot has collected so far. If you use this data for any type of #data #analysis or #AI and/or #ML projects I would love to hear about it!
Safe travels this #holiday season. ✈️🎄

For #AI applications that allow multiple model selection, I wish they'd offer functionality to run a query on multiple models so you can compare and contrast the results to determine which is best for the given use case. I never know which AI model to pick anymore. 😅

Semantic Versioning is great for many things. Comparing versions is not one of them.

Also, #Apple should really open source their documentation. I'm sure so many people (myself included) would be happy to contribute improvements. It would be game changing for the entire #iosdev ecosystem.
(I know there is probably a lot of behind the scenes tooling challenges in making this happen, but Apple really needs to prioritize it since they aren't prioritizing good documentation themselves).

If you're working with the #Apple #Intelligence ImagePlaygrounds API and can't figure out why the `sourceImage` property isn't working, I spent a good part of today debugging this issue. I wrote a StackOverflow question describing my findings. #iosdev https://stackoverflow.com/q/79196270/894067

So the latest #nostr #spam is a "dm-reporter" account. Do people really have nothing better to do than build these spam bots?

2024-09-14 20:32:11 GMT

For #nostr #developers how do you decide which relay URL to use? I have a system that transmits notes to multiple relays, but for things like reposts (NIP-18) struggling to decide how to determine which relay URL to use for that.
Obviously choosing an unreliable relay or a relay that eventually goes offline isn't a good practice. And it doesn't look like there is a way to define multiple relay URLs.
What do you all do for this?

@npub1nzr…36v5 on #nostr now supports radar images for certain types of delays! This took a lot of engineering effort throughout the entire stack to get working. #Mastodon & #Bluesky bots had this feature for a while, but due to the decentralized nature of #nostr this was more difficult than just uploading an image to a central server.

2024-09-04 00:15:57 GMT

- reply

What client are you using to do that? I didn’t specify and that is my bad. But I’m talking about just raw #nostr events. Not things that clients do special.
Looks like some image posts on #nostr contain tags for imeta. And things like blurhash. Which I’m not entirely sure how to generate.

2024-09-03 23:48:37 GMT

What is the suggested method for adding an image to a #nostr post? Just add an image URL to the end of the post content? Is it necessary to add any extra tags for this? If there is a NIP that someone could point me to for this, that would be great too. #asknostr

2024-08-31 23:08:35 GMT

Yep. I mean maybe not 100% from scratch. Most software has some external dependencies these days. But coding it yourself instead of just using existing nostr relay software that someone else created.

2024-08-31 15:17:38 GMT

Even bigger challenge. Write your own relay software.
I wrote my own relay software before. Sadly haven’t worked on it in a while, but really taught me a lot about how #nostr works.
And definitely reach out if you have any questions!

2024-08-28 02:15:35 GMT

Just pushed a major update to @npub1nzr…36v5 vastly improving the logic for determining the reasons behind delays. This should lead to more detailed and accurate delay explanations. Additionally, many infrequent airport delay reasons have been added.
There is still more work to be done, but this is meaningful progress towards increasing delay transparency for travelers.

Ok I didn’t mark any relay as an “inbox”. I’m still really new to the whole inbox concept. Is there documentation for it? Or do you have a quick explanation of it?
I’ll try setting it as an inbox when I get some free time later today.
I really appreciate your help!! I was actually using Coracle to test this in the first place 😝.

This. Documentation is tough. It’s the boring part of software engineering. But if you’re gonna build software that you expect others to use, it’s critical. Even more so for a protocol like this. You have to brute force it to be a priority.

NIP-17 is awful. I can’t even get it to work. Obviously I’m doing something really dumb, but spent a few days before giving up.
This is exactly where #nostr could fail. The NIP process is long and tedious, yet incomplete. Is anyone thinking about the scalability and long term impacts of these proposals? More time should be spent on that as opposed to all these dumb little proposals that have almost no usage. Let’s get the foundation right first.

2024-08-07 17:33:35 GMT

- reply

One other thing about this I forgot to mention. You should be able to view the entire history the npub. #nostr doesn’t really support deleting notes, so you should be able to view the entire history to backup my claim that it wasn’t reused and has only been used for that project.
The whole point of #nostr is to verify not trust. So don’t trust my word, verify it yourself 😉.
If you do happen to remember why you blocked it or anything, please let me know. I’m committed to addressing any concerns or problems the community has in regards to it. (Also all the source code is open source, so also trying to be transparent too) ✈️

2024-08-07 13:36:34 GMT

Nope. The npub I mentioned has always been used for that AirportStatusBot project and has not been used for anything else.

2024-08-07 02:31:53 GMT

@npub1nzr…36v5 now supports direct messages! Message the bot and ask it questions and it will reply with some useful information. This feature is in alpha, and still in active development. But wanted to ship it to get feedback.
On a more technical note, NIP-17 I couldn't get to work at all with it (only supports NIP-04). Asked in the #nostr telegram and didn't get any replies. If anyone wants to take a look and help debug, let me know. But I think #nostr is on track to fail miserably if developers can't even figure out how to use non-deprecated standards after spending days on it.

2024-07-21 00:34:46 GMT

As far as I know, NIP-42 is implemented in Damus TestFlight. It’s just requests made prior to that auth command aren’t retried. Which is a (fairly) minor edge case. By and large it should be working tho.

One thing we do have to think about is how this will work for phrases (ie. if you have a mute that contains multiple words). Should be possible, but an edge case we need to think about, and ensure we handle correctly.

I think there is a difference between users, and relay operators here. The biggest benefits to interoperability are for users.
I think the other assumption with your comment seems to be that of a single relay model. #nostr isn’t a single relay (or server) model. It can be if the user decides to go down that path. But it doesn’t have to be.
Client devs tho benefit off of interoperability because it brings more content into #nostr. Which leads to a better user experience.

Are on-chain fees cheap and accessible right now? It truly depends on the use cases. Some use cases are completely impossible today due to on-chain fees.
I wouldn’t say on-chain fees are cheap or accessible today.
If you’re moving lots of Bitcoin, then sure it’s cheap. But smaller transactions exist. And it’s big business.

Love that you’re thinking through the UX side of this. We need to always remember the 99% of users instead of just the 1% of super tech savvy users.
If we want #nostr to win it needs to be dead simple and a great experience for those who aren’t super tech savvy.

2024-01-18 00:37:14 GMT

- reply

Well not everyone uses #nostr. Just as an example @npub108p…yev6 runs a bridge that lets nostr users interact with ActivityPub users.
If you’re only using your own relay, and not reading or writing to any other relays, then you probably don’t benefit from that. (Unless of course you get those bridges to read & write from your relay).

Sure! NIP-42 is a way for clients to authenticate to relays. From the user perspective it’s seamless and invisible to you.
But it enables a relay to know what user/pubkey is connected to their relay. This is primarily used for paid relays (ex. filter.nostr.wine) or relays that only send your DMs to authenticated users (ex. nostr.wine).
filter.nostr.wine for example before NIP-42 required you to change the URL to include your npub so they knew who was connecting. However that isn’t very secure and it didn’t provide true authentication.
I’m sure there are a lot of use cases I’m missing. But at a high level it allows a relay to verify who a user/pubkey is that is connected to their relay.
Hopefully that helps explain it.

2023-12-14 00:28:21 GMT
