Subject: What we've been working on: Diaspora “Sharing” Model

Hello Diaspora,

------- TL;DR
We are implementing a new way to connect to people online.  It is getting
rolled out next week. It is somewhere in between a follow and a
bi-directional relationship.  When you share an aspect with someone, you
start seeing their public posts right away.  If they share back, you have a
fully bidirectional relationship.
--------

In a few days, we’ll be upgrading Diaspora’s relationship model to something
we call the “share”  model. We believe it’s a more elegant way to connect
with other people on the network.  We’ve been working on it over the past
month, and we’re happy to announce that it’s ready to go.  Before merging
this work into Diaspora’s master branch and deploying this feature onto our
on servers, we want to give you a heads up and explain what this new model
means to both end-users and developers.

At it’s core, “sharing” is how we’re implementing asynchronous
relationships.

Our current bi-directional relationships fall short. They introduce too much
friction to exploring all the wonderful public conversations on the Diaspora
network (especially for new users).   New users face a lonely, empty site.
 We considered implementing the familiar follow model, but we wanted a
system that embraced the asynchronous nature of a follow without losing the
benefits of aspects.

For users the interaction is only slightly different:

Putting another user into an aspect means sharing with them.  Sharing
includes following; you’ll see another user’s public posts in your stream as
soon as you put them in an aspect.   They, in turn, can immediately see the
face that you want to present to them through your profile private posts.

Once two people are sharing with each other, the relationship between the
two is exactly the same as what we currently have:  Connected people able to
share privately with each other. This allows for more intimate relationships
while addressing the “friction” and “loneliness” that we originally found.

For developers not much has changed:

These changes have allowed us to simplify our data model.   We’re dropping
the Requests table and replacing it with two columns in the Contacts table.
 Upgrading means pulling and running a migration that will translate the
Requests table over to the Contacts table.  That’s it.

For pod-runners:

Since the new model is not backward compatible (although no permanent damage
can be done by contacting an out dated pod) on the protocol level, it would
be good to upgrade at the same time. We are going to do it at 10 am PDT,
Monday May 16th<http://www.timeanddate.com/worldclock/fixedtime.html?msg=Diaspora+Sha...>let
us know if that's problematic for anyone.

During the time that servers aren’t running the same version, changes in
relationships between servers running different versions won’t work, but the
upgrade will clear any broken state left in the requests table.

We’ll be happy to answer any questions you might have about this transition.

Daniel & Ilya

P.S. We’ll write a blog post about this in the next couple of days.

Okay a few questions:

Will I be able to comment on public posts I receive when I'm following someone?

Will there be a list of people following me? Will it be public? If so it should be possible to turn it off.

What happens to currently broken connections, i. e. when someone has a pending request but the remote pod never received the request?

What happens when the connection can't be established, will the user be notified or just think he is following the remote by never receive anything?

Will there be a flag indicating if its a bi-directional or a follow contact? Will that flag be switched back if one party removes the connection?

Will a contact I'm following be removed from the lists for mentions and conversations so a user isn't trapped on thinking he can and successfully did contact him?

Thanks,
Jonne

Which branch will you be merging? Is that the "follow"
branch available through the github repository? It would be good to look at
the code

Currently in our branch (follow), only you can see the list of people who
are sharing ("following") with you.

We can either delete all pending contacts and incoming requests, which would
reset the state, or we could unsafely assume these connections have been
made, and create uni-directional relationships.  This obviously, is up for
debate.  Glad you brought it up.

In the latter case, users will be able to hit "unshare," then "reshare,"
which would reset the state as well.

>> What happens when the connection can't be established, will the user be

Synchronization is still going to be an issue that we need to address.
 (Sort of a scope greater than the share model.)

If you're referring to some sort of badge placed on a user's profile that
you're viewing, no.  You will be able to tell by whether or not you can send
that individual a message, though.

You can only send messages and mentions if you're guaranteed to be able to
contact them (via permissions).

We're definitely going to work towards lowering the barrier to entry to
running a server -- both on your personal machine and on other service
providers.

Hey Diaspora,

Just a quick update, we have to be out of the office today and are going
to deploy the share model tomorrow same time (10 am PDT, Tuesday May
17th). We have not merged it into master yet so don't worry if you
already did a pull.

Thanks,

Ilya

I apologize if this has been addressed, but
1) has any thought been given to aiming for Heroku or Engine Yard
deployability?
2) are there Chef recipes for Diaspora server provisioning?

I think 2) is going to be a huge deal... if a VirtualBox server could be
provisioned using Vagrant and Chef, with MySQL all set up and ready to roll
so that deploying from the latest master on GitHub is all that needs to
happen... that could completely change the 'barrier to entry' situation.
VirtualBox image + Vagrant + Chef == easy deploy on your own metal.

I'm working on building an image of my test pod server, once I have
something I think looks reasonable, I'll throw it up on GitHub.

Subject: Re: What we've been working on: Diaspora “Sharing” Model

I've been doing some work on Heroku compatibility, but it basically means dropping Jammit altogether. From what I've seen, Jammit requires the ability to actively edit contents in your application directory, which is not possible on Heroku (for obvious security reasons). That's been the major roadblock. I'm working on getting my build (http://github.com/tubbo/diaspora) to function using Rails 3's internal asset cache helpers, in order to allow more people who may not have a lot of Rails or sysadmin experience to get a pod going somewhere. I feel that quick setup will be a VERY important part of Diaspora's future success as a distributed social networking platform.

However it should be noted that Jammit's asset packaging system seems to be far more advanced and configurable, and we should probably be using it, so I don't think it needs incorporating back into the master repo. Perhaps we should make a "heroku" branch to hold a build optimized for such as service?

We've been working towards postgres compatibility and removing our
non-rails processes.  We'll likely want to replace the websocket
server with long polling, for instance.  Jammit is an optimization, so
as long as it can be taken out of the project in a smooth conditional
way when it can't be used, don't worry about removing it.  I'd rather
not maintain a patchset in a branch, because that takes labor, and I
don't think it will be necessary.

Our chef scripts have gotten stale lately, and they're targeted at
CentOS, which I've been dissatisfied with.  I'd like to rewrite them
for Debian, or something else with an up to date libcurl.

Targeting Debian is a good choice, IMHO. After RailsConf I'll try to do a
fresh snapshot of a Debian VirtualBox suitable for use with diaspora (and
vagrant).

I can't recall, but is diaspora using Modernizr? I feel like ditching
websockets is a step back, but maybe reverting to long polling based on
feature detection?

Just a thought.
