I've tested several relays (only one at a time) but I'm getting this timeout error each time I'm trying to sign an event with frost2x and Igloo.

This is a small update, probably significant only for tech-savvy users, but it marks the path to a more transparent, secure and privacy-oriented approach to multi-signature bunkers.

We at #GitCitadel are almost a quarter of the way toward our *git server goal*. A hearty thank-you, to everyone who donated. We have now, correspondingly, lowered the monthly relay rate from 5000 sats to 3750 sats.

We at #GitCitadel have spent this week pricing out remote servers and brainstorming; considering the most cost-effective, but still performant, way to implement a public #gitserver based upon Nostr. In order to help us front the rental fees and lower the price to individual npubs, we have begun a new https://Geyser.fund goal.
The resulting server will have multiple #gnostr implementations and tools on it. We are planning to begin with:
* the #GitRepublic API, that will make it possible to log in to git with your Nostr signer, and will trade out e-mail communication with Nostr notes,
* an HTTP-based git server (the first thing that will be going online, so that everyone can move or mirror their repos),
* a paid AUTH relay https://gitcitadel.nostr1.com (currently 5000 sats/month, to cover all the running costs, but we hope to bring that

tl;dr summary
There was a proliferation of browser-based applications circa 2005, enabled by technology.
- They tended to not be CPU or graphically intensive, due to browser limitations.
- More recently, browsers have chipped away at these limitations.
- An IT ecosystem has developed to accommodate web-based SaaS apps, facilitating browser-based software.
- Browser-based applications have lower friction and more natural collaboration.
A stack to enable this might include:
- Generalized CRDT data layer
- UI component framework
- Standardized integrations for automation tools
- “Lambda but for WebSockets”
The downsides are:
- Cloud lock-in concerns
- Non-parity with native
- Security isn’t a given

So excited to announce we have signed releases for:
- Igloo: Frostr keyset manager and signer (Desktop App)
- Frost2x: Frostr Signer Extension (Browser Extension)
This is a secure & minimal setup for operating a 2/3 multisig for your NSEC
Please give it a try, be extremely cautious, and give us any feedback! @cmd @bitcoinplebdev

Smart platform-provided algorithmic feeds like those from X, TikTok or Instagram will NEVER work on Nostr.
Anything that requires filtering from a "global feed" of all notes and delivering that to specific users will never work on Nostr because there isn't and there cannot ever be a global feed on Nostr.
If that is what you think Nostr needs to be good and popular then you'll first have to destroy Nostr by turning it into something else, and then you can implement it.
The alternative is to create something new, a new way of doing discovery, something that actually works nicely within the Nostr constraints, something that actually only works on Nostr because only Nostr has these distributed independent servers with specific owners, specific rules, different users, personalities and preferences.

My dad qualified for the UCI World Championships Gravel last Sunday in his age group M65 💪🏻
I also saw his finish, which was a very special unique moment as he stopped racing when I was born (38 years ago). Now he slowly is getting back in this game and I see he is really enjoying it.

This is an extremely basic prototype that only barely works (user beware!). However, I think it highlights what is amazing about building on Nostr. I was inspired by this post, and then able to build a client in 3 days almost entirely with AI.
The opportunity to bridge social behavior with "other stuff" (in this case, books via Open Library API) is huge. This concept could work for any type of content, not just books. Music, Movies and TV, games, etc. — all on Nostr.
The process of building on Nostr with AI also demonstrated a few gaps in the ecosystem where AI-ready tools were missing or failing, so there is definitely opportunity to grow there.
Shout out @Alex Gleason 🐍 who had many of these ideas first, helped me with lots of the

Could this be an interesting revenue model for Nostr apps with @Zapstore? Having an appstore subscription which gives you full access to a list (or all) nostr apps? With revenue splits to the developers of the apps.

Consider Nostr a reset of an internet that was hijacked decades ago empowered by a borderless freedom money.
Nostr + Bitcoin + Value 4 Value.
One trap a newcomer always falls into when exploring Nostr is comparing one app to another. In this case, the lowest hanging fruit… Twitter (X).
The interoperability aspect and ownership of an account is revolutionary. Would if that follow you purchased had no walls and had no expiration? Would if it went from YouTube to Instagram to Twitter to Facebook to Spotify and etc. A portable social graph.
How would that compare?

During Bitcoin Amsterdam at the Nostr booth and @Nostrdam we used NFC cards to find and follow npubs. So I just let someone else scan my NFC card and my profile was there instant. It’s the best way to share your profile in meatspace. So instead of having a simple NFC card I see a great market oppertunity to deliver Nostr branded NFC tags. Who can build that? #growNostr
