World: r3wp

Under Ubuntu10.04, the function "copy to the clipboard" is local 
to ALTME only, This means that I cannot use it to copy an url or 
a text to another program or document. Any correction ?

Copying to the clipboard in AltME goes to linux's X clipboard - this 
one is pasted from by middle-clicking the mouse.

And the opposite direction, hilighted text outside of AltME is automatically 
copied to the X clipboard, which can then be pasted here

Thank you from a linux newcomer ;-)

I think I need to get a Graham2 account ... posting PMs is taking 
over 10 seconds to what seems like a minute sometimes.

or just rename your personal pm file, make it empty ... will that 
resync the old one?

I'll set you up a second account for testing Graham.

48 seconds to post a PM to Sunanda :(

I also have a fairly large private messages file.

Try with someone who does not -- say a Hello message to a new member.

2 minutes to send "ok" to Gregg.

It only takes 1.2 seconds for light to travel from earth to the moon!

I have maybe 30 private messages in total, if you want to check

That suggests Gregg is on Venus.

lol

AltME is REALLY REALLY slow for me.

Sunanda is from Mars

What's the problem .. flat files?

its become slow for everyone.  is it time to start up a new world... 
or update the server its running on?

PM 100 seconds to Izkata

if we do make a new world, I'd name it differently than just going 
to rebol4... its misleading.

so it doesn't seem to mean a PM message store issue

Debugging without the source is a little silly

Very slow for me right now. Inconsistently so though. I doubt it's 
flat files at fault. I think it's the sync/diff/publish model that 
doesn't scale. Only a guess since I don't have the code.

What's wrong with Rebol4?  It'll keep all the worlds in alphabetical 
order!

I think when people PM it bogs down the whole server throughput, 
cause its effectively sending MBs of data through the net.

or is it?

maybe use Git as the basis for a new chat system

the number at the end gives the impression that its a world to speak 
about that version of rebol.

the R3 chat architecture is VERY nice... it just needs a GUI client.

We could rename to somethin like REBOL-Darknet or something, which 
makes it more interesting to people.

I was going to propose  REBOL-devnet   :-)

I'm cool with that too.

how about Rebol-and-no-trolls-world

lol

Well, I'd imagine that this is a major problem for Altme ... so Carl 
will want to fix it.

After all there are some people paying for worlds ...

But IOS messenger never got fixed .. so maybe it won't :(

My paid (not hosted) worlds aren't affected by this.

because you don't have enough messages

I just tried sending Gregg a PM on REBOL-gate.

REBOL-gate is a tiny world that runs on the same server as REBOL3.
The PM took under a second.
That suggests world-size scaling is the issue to focus on.

Exactly

NetLImiter won't show stats for me right now, so I don't know what 
AltMe does in that regard. I also can't just the R3 chat architecture, 
but the CLI for it isn't terribly intuitive to me.

Yes, Graham, my point is that I don't think this will be a priority 
for RT to address unless a hosted client has a big world.

I've just asked Carl to help in maintaining Altme in another comm 
channel... hopefully he'll see that and reply to me in a not to distant 
future.

IMO the fix is simple. Use a database as backend. Never understood 
why this step is so hard to do. Even with 1 Mio. messages you won't 
feel a slow down.

So, db on both servers and clients?

Interesting, why use a DB and add bloat, why not just write just 
enough code to keep it fast?
For example, loading in messages in groups of 100....

That's essentially the data structure we use in the archive at REBOL.org, 
Reichart.

Works fast and has scaled so far -- with nearly 150,000 posts from 
this world:
   http://www.rebol.org/aga-groups-index.r?world=r3wp

Graham, yep, that's how I would solve it.


Reichart, well, 250KB for SQLite is not that much bloat IMO and supports 
full-text searching as well.

I love AltMe, but it has things that annoy me as well. Since we don't 
know exactly why it doesn't scale (yes, we can guess), I don't think 
just making the back end a DB is a guaranteed fix, or perhaps even 
that simple. And I don't think it will happen. I fear the R3 chat/rebdev/??? 
model will scale even worse than AltMe as I think the msg db is a 
single file and still a naive implementation designed for small-scale 
use.


Like Graham, I've thought that something like Git--a system designed 
for distributed, differenced, repositories of information--might 
be used. I haven't seen it done however.

What ar our options?

1) Live with AltMe, and roll worlds when they get too slow.
2) Find an alternative.
3) Implement our own.

Is #1 painful enough to drive us to #2 or #3?
