#102Opening a demo chat app URL in Private Mode in Firefox results in perpetual "Loading..." screen and the following error on the console: Uncaught (in promise) DOMException: A mutation operation was attempted on a database that did not allow mutations.
Thanks for reporting, created an issue: https://github.com/gardencmp/jazz/issues/498
In this case we should fall back to using in-memory state only

npx jazz-run sync Either locally or on your server. And then point the app to that! Edit: re pricing Super preliminary, curious to hear everyone’s thoughts
Storage seems reasonable, maybe even a bit too cheap, but the sync minutes look way too expensive. One problem is with end-user monetization: users are used to pay for storage, but not for how much time they can use your app.
For a small storage-heavy indie app I have, I'd pay $79 for base price, $45 for additional storage, and $1500 for sync minutes.

#104Where are the information about the company? I cannot find an About Us, where they are based, etc?
Founder here - we’re working on that page, so far there’s just info on me on https://gcmp.io/team But I was able to hire a couple really good first people recently! We’re based all over Europe. Let me know what else you’d like to know!
Are you looking to hire at all? This is the kind of technical work that I'm very interested in.
I'm based in Europe.

#105Curious how this compares with Meteor.
Meteor works on top of a traditional backend (typically MongoDB afaik?) to give you full-stack reactivity. Jazz implements essentially a distributed database with permissions based on public-key cryptography, so you can meaningfully create, edit, share and store data on the client (even while offline), which gets synced to other users and devices (and stored in the cloud) whenever you're online
Is this synchronisation (theoretically) possible over p2p communication protocols like Bluetooth or wifi direct?
I would more than love to have local networks that can be emergent and growing and shrinking in this way.
Reminds me of my student days when I was traveling in the train, wondering why we couldn't have a p2p social network for people who are in this train _right now_

Thanks, this is very helpful. If it's unfeasible for a small indie app then that's a bug in the pricing.
If you have time, I'd love to hear about your app and work out alternatives (not just for you, but for everyone)

Thank you for this. Many years of browser usage and I never knew this.
Such is the years long removal of affordance from the UI. Netscape 4 had a small downwards arrow to indicate a submenu for the backbutton.
On Firefox it apparently disappeared in 2011

update: it's not the amount of people in it that broke this room https://news.ycombinator.com/item?id=41775047
update 2: should be working now (give it a second to fully load)
update 3: added rendering of only the newest messages per default, scroll-to-bottom, and message length truncation to deal with the spam a bit better
Re: Jazz – Apps with Distributed State
#110This is absolutely fantastic! I have been looking on and off for something like this for years (some of the things I have used are CouchDB, command/event sourcing, and ditto.live).
I have not been able to read the docs fully, but some questions:
* How do you handle state that is too big to send to the client fully? In a chat application, does the client need to have the whole channel history, or is syncing a subset of that supported? * Does permissioning support partial CoValues? For example, "You can edit the contents but not the title of the 'blog post #11' object" * Do you have resources about the suggested data modelling? Things like how granular should a CoValue be and what the trade-offs are. * How do you handle deletion? Do you tombstone? Is there a way to fully scrub a value from history (to support, for example, GDPR's right to erasure)?
