ralphmFor those with some German skills. For those without, the executive summary is: "Carbons >>> Hangouts, Stream Management is awesome. Yeah. The future. Yeah."
simonhe's a happy camper. Now we just need to get some mobile clients sorted.

ralphmI really like watching http://display.ik.nu/xmpp.
Tobiasyou and your self-signed certs ;)
ralphm:-D
ralphmBetter than nothing, I suppose?
Tobiasprobably
Tobiasit says via Twitter, are there other source that go into it?
ralphmNot 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.
ralphmIncluding ActivityStreams.

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

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

dwdxnyhps, To be fair, if you send more than 2^96 stanzas, you've a better than even chance of hitting a collision.
winfriedhas left
xnyhpsYou want to send the entire internet how many times? ;)
dwdxnyhps, Although I imagine we could mitigate that by recommending people restart their XMLStream at least once before the heat death of the universe.
Lloyd:)
jabberjockeanybody have a good federated xmpp domain for groupies to the philips hue bands we are startig around the world

dwdxnyhps, Oh, he's right.
dwdxnyhps, 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.
xnyhpsI 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?)
dwdAh, yes.
KevIt is worth noting, potentially, that while they're a generally bad idea, 0-based integer counters do have bandwidth going for them :)
Tobiasyeah...think of all the savings....when outputting tons of bloated XML
Tobias^^
dwdOh, don't start.
Tobias;)
xnyhpsUse compression, and pick random parts from the stream so far to use as ids.
dwdThat actually works.
KevAbsolutely.
KevUse an RNG to select bits of a stream to avoid needing to use an RNG.
dwdKev, No, this is for saving bandwidth.
xnyhpsJust hope you don't actually pick the content of a message. :P
Kevdwd: It can't possibly save bandwidth.
KevHowever 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)
dwdKev, 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.
KevAnd by doing so, you're reducing the entropy.
KevYou're talking about selecting your randomness very carefully so that it's not too random :)
dwdSmallish number of bits.
Zashhas joined
dwdBut it's OK, because you could send the *real* random data earlier in the stream to refer back to.
KevThis 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.
xnyhpsI was entirely not serious.
dwdxnyhps, Nor me. But I'm wondering how far I can string Kev along. :-)
Kevxnyhps: You, I believe. Dave I have less faith in...
dwdKev, 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?
dwdI was proud of that one.
KevThat bit I assumed was a joke. The rest I was less convinced about.

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