hi danny

Danny Burkes

hi- what's up?

7:03am (March 20, 2007) 26x26

there

hmm. are you still using comet with jetty continuations?

cause i don't see any open connections here

7:04am (March 20, 2007) 26x26

Danny Burkes

Yes, definitely still using it. Connections are by dynamic script tag, however, not by XmlHttpRequest, so you won't see them in something like firebug. You'll have to use a network sniffer or HTTP proxy to see them.

Who are you?

7:05am (March 20, 2007) 26x26

there

me i'm a rails developer from germany. im just launching a little startup called playtype.net

we're building an event calendar for germany

7:06am (March 20, 2007) 26x26

Danny Burkes

cool

there

and i want to have live messages everywhere

Danny Burkes

Well we are very happy with Jetty on the backend, that's for sure

there

have you seen activemq?

that handles queues/topics

7:07am (March 20, 2007) 26x26

Danny Burkes

Heard of it but haven't looked at it- we do everything by hand in a custom servlet we wrote

there

hehe yeah. thanks for your help by the way!

jw just working with me btw. he's fighting with jetty and activemq atm

Danny Burkes

I'll check out activemq, thanks

jw

the script which is dynamically loaded is javascript and the browser loads it and runs it? is that right.

7:12am (March 20, 2007) 26x26

Danny Burkes

Yes. In our case, the script just looks like "callbackFunction(jsonDataObject)". We're really only concerned with the jsonDataObject. The callbackFunction is just our way of getting notified when the rpc call completes.

jw

ok i understand thx

Danny Burkes

The example I pointed you to demonstrates that

7:28am (March 20, 2007) 26x26

there

hmm okay. so if in a page i want to establish a 'comet connection', i create a script node that points src to, say, /comet.. and this creates a continuation on the server. then when an event happens, the server resumes the continuation and sends back the following javascript: callback(event_object).

Danny Burkes

exactly

then you do it all over again

so it's not really a continuous connection between client and server- it's a long poll that is automatically reestablished by the client after it processes an event

of course there are many complications in the details but you've got the basic gist of it

7:30am (March 20, 2007) 26x26

there

ok

ty again. i think jw is going to give it a go!

Danny Burkes

feel free to call again if you have more questions

7:32am (March 20, 2007) 26x26

there

ok ty appreciate it. pretty fiddly stuff if you've never done anything similar

Danny Burkes

it's taken us a year to get to this point

7:34am (March 20, 2007) 26x26

there

wow 1 year! how long do you think it'll take to develop a dynode version that basically goes?

Danny Burkes

not sure what you mean "basically goes"

What I mean is, it's taken us a year to get to the point we're at now, where we can handle 1000 people chatting at once with no problem. As you said, "pretty fiddly stuff". The devil is in the details.

gotta run now but I monitor this room with Radar, so just shout if you want to chat more

you still there danny? hehe bit hard to /synch

ok i'll just shoot my question at you - you can answer when you see it

. i asked you a few questions about comet the other day, since i'm implementing live stuff for my event calender site. i have dynodes on the client side, and jetty with activemq on the server side. rails <> jetty communication is using STOMP. but now i wonder how where i should connect to from the javascript. on the server side i have 2 processes: localhost:3000 for rails, and localhost:8080 for jetty. now i need to get everything under :80 cause of firewalls etc. how have you done this? putting a proxy on the server side (like litehttpd) is going to push the connections problem which jetty solves onto the proxy - not good. but there's no other way that i can see of getting 2 processes to listen on :80 on the same machine. how have you solved this? i see you're connecting to all sorts of 19.www, 10.www etc.

any pointers appreciated - getting to the tear your hairs out point

be back here tomorrow. is there an email add i can reach you on?

hey, are you there? =)

oh, 7 am in you part of the world.. probably not.

Ok, I'll just tell you what this is about, and you can read it when you wake up.

We put lingr to the test yesterday when we used it as a chatroom for a tv-series on Swedish national television. I work for a small production company that makes a kind of alternate reality game that goes with the drama. We had over 200 people in the room at some point, and it worked great. So super thanks for lingr.

But, the reason I'm trying to reach you here is that one person (a troll) came into the chatroom and poster a very sad and disturbing image of a killed cat. It's a little photo "essay" where a cat is hung and mutilated. What I'm asking is if there is any way for you to remove the link to this image. We are changing the password and just giving it out to a more trusted group, and I won't ask about this ever again. Or if there is a way that I haven't found out where a room creator can delete messages, please tell me.

The message this is about is here: (password for chat if needed is "vadvillni")

I'd like to congradulate your Lingr team of developers. I find it's the best platform. We use it to communicate and train Persons with Disabilities. We even use it for Video Training chat sessions for members from across the world. Kudos I'll have to read your Blog as I need coaching and mentoring in web development (Complete Newbie). Any tips you can share would be appreciated Sir.

Hello Danny

Question here

Danny Burkes has joined

2:58pm (May 02, 2008) 26x26

Danny Burkes

Hey, what's up sly

Rocky_IV

Is it possible to transfer ownership of a Lingr room?

Danny Burkes

We have no UI to do that, no

maybe there's some workaround if you can explain what you want to do

2:59pm (May 02, 2008) 26x26

Rocky_IV

What are the options then sir

Can the rooms be deleted and then recreated

Danny Burkes

sure, but you lose the archive that way. If that's acceptable, you can go that way

3:00pm (May 02, 2008) 26x26

Rocky_IV

Well the Exec who used to be on our exec. has left.

Wecan contact her by email

Danny Burkes

is loosing the archive acceptable or is that a problem?

3:01pm (May 02, 2008) 26x26

Rocky_IV

No i don't think the archives will be a problem

We can archive all the URL Links

before deleting room

3:02pm (May 02, 2008) 26x26

Danny Burkes

not sure what you mean "archive all the URL links". If the room is deleted, the messages are deleted

Rocky_IV

We love Lingr

Danny Burkes

great to hear it

Rocky_IV

Find it way better than Yahoo chat

Danny Burkes

well, yeah

3:03pm (May 02, 2008) 26x26

Rocky_IV

well we shall copy and paste our Video links before deleting room

Danny Burkes

if it's ok that the archives are lost, just create a new room. You don't even need her to delete the old room, unless you want to re-use the old room alias.

Rocky_IV

I'm run muliple websites for persons with Disabilities

We provide Persons with Disabilities with free technical computer support

3:04pm (May 02, 2008) 26x26

Danny Burkes

if the room uses an alias (human-readable part after www.lingr.com/room), then she'll have to delete the old room (or at least relinquish the alias) before you can start using it.

3:05pm (May 02, 2008) 26x26

Rocky_IV

Yes we will want to reuse the Room's Names

We have 2 rooms

Enable lingr chat

and Moderator Central

3:06pm (May 02, 2008) 26x26

Danny Burkes

Then she'll need to delete the old room before you can re-use the name. She can do that by going to the room settings page, or by canceling her Lingr account

if she cancels her account, all her rooms are deleted in turm

turn

3:07pm (May 02, 2008) 26x26

Rocky_IV

about how long does it take to be deleted from Server

Danny Burkes

somewhere around 100 milliseconds

Rocky_IV

thats fast

I can't delete my girlfriend that fast

Danny Burkes

it happens as soon as she says "delete this room" or "cancel my account"

Rocky_IV

lol

Were coming up to our 2 year anniversary

Can an mp3 player be inserted in Lingr chat

3:09pm (May 02, 2008) 26x26

Danny Burkes

if you just paste a .mp3 link, it becomes a player automatically

lemme find one...

Rocky_IV

were trying to get a special song created for this event

I run a Video technology series in Lingr

weekly sessions
