For those with some German skills. For those without, the executive summary is: "Carbons >>> Hangouts, Stream Management is awesome. Yeah. The future. Yeah."

he's a happy camper. Now we just need to get some mobile clients sorted.

I really like watching http://display.ik.nu/xmpp.
Tobias
you and your self-signed certs ;)
ralphm
:-D
ralphm
Better than nothing, I suppose?
Tobias
probably
Tobias
it says via Twitter, are there other source that go into it?
ralphm
Not for this feed, no. But ikDisplay can have multiple different sources. It was originally created as a back channel for the federated semantic-web-like social networking sites I worked on at Mediamatic.
ralphm
Including ActivityStreams.

Tobias: do you have any use cases?
Tobias
ralphm, just wondered about the sources...but i suppose not many networks have sources for public streams anyway
ralphm
Yay silos.

Tobias: That said, it probably should have support for Superfeedr. However, its XMPP PubSub API has some non-standard warts.

xnyhps, To be fair, if you send more than 2^96 stanzas, you've a better than even chance of hitting a collision.

xnyhps
You want to send the entire internet how many times? ;)
dwd
xnyhps, Although I imagine we could mitigate that by recommending people restart their XMLStream at least once before the heat death of the universe.

anybody have a good federated xmpp domain for groupies to the philips hue bands we are startig around the world

dwd
xnyhps, Oh, he's right.
dwd
xnyhps, I think you hit parity on the probability of hitting a 10 hex-char (ie, 48-bit) hash fragment after only 4.5 million years on a stanza per second.
xnyhps
I meant outputting the first 10 bytes of the hash, not the first 10 bytes of the hex representation of the hash, so 80 bit.
Lloydhas left
xnyhps
(Also, 10 hex-char is 40 bit, isn't it?)
dwd
Ah, yes.
Kev
It is worth noting, potentially, that while they're a generally bad idea, 0-based integer counters do have bandwidth going for them :)
Tobias
yeah...think of all the savings....when outputting tons of bloated XML
Tobias
^^
dwd
Oh, don't start.
Tobias
;)
xnyhps
Use compression, and pick random parts from the stream so far to use as ids.
dwd
That actually works.
Kev
Absolutely.
Kev
Use an RNG to select bits of a stream to avoid needing to use an RNG.
dwd
Kev, No, this is for saving bandwidth.
xnyhps
Just hope you don't actually pick the content of a message. :P
Kev
dwd: It can't possibly save bandwidth.
Kev
However many bytes of entropy you want to have are going to take that many bytes to transmit.
Kev
(At least that many bytes to transmit, you could transmit lots with little entropy, I realise)
dwd
Kev, No, not at all. If you select carefully, you can generate random identifiers that are always encoded by zlib as a reference, hence three octets or so.
Kev
And by doing so, you're reducing the entropy.
Kev
You're talking about selecting your randomness very carefully so that it's not too random :)
dwd
Smallish number of bits.
Zashhas joined
dwd
But it's OK, because you could send the *real* random data earlier in the stream to refer back to.
Kev
This is close enough to the edge of my knowledge that I accept I could be wrong in this. But this sounds like Not A Good Idea.
xnyhps
I was entirely not serious.
dwd
xnyhps, Nor me. But I'm wondering how far I can string Kev along. :-)
Kev
xnyhps: You, I believe. Dave I have less faith in...
dwd
Kev, You didn't like the suggestion that you'd put arbitrary random data in the stream, then refer back to it, so you get both the compression *and* the randomness?
dwd
I was proud of that one.
Kev
That bit I assumed was a joke. The rest I was less convinced about.

Right, I think that's comments for the people who asked for them on GSoC ideas given.
