Aftermaths of a great event

first i want to thank you all for participating! We were about 12 people in each of the two meetings we had on sunday. Considering this was the first time we met on this new base all went extremely smooth.
For me there were some interesting lessons to be learned:

-> the server  is able to provide enough power for HGAC meetings. Aside from the slowdown i will descibe later everything went very smooth.

-> doing a jump with large groups of hypernauts stresses server too. Our jump to TGIB slowed that sim down to near death. I think Vanish will write something about that.
-> setting up a freebie area needs a bit of planning and communication. It was amazing to see the amount and variety of freebies that were placed on the freebie area. But... ;-) ... i feel we should talk about what should be placed there. Since we could come up with a sheer unlimited number of good stuff to share this would blow up the ressources needed by the simulator. To keep this one as smooth as possible i suggest to keep just some "essential needs for the hypernaut" here. It should provide some acceptable looks to allow new hypernauts to start exploring the hypergrid. If we want to set up a hypermall this should be on a dedicated sim (server?) of it own.

-> trying to do too many steps at once isnt good. Many new accounts have been created, most of wich needed to have some initial outfits. The freebie area was filled with stuff. We had many new visitors from other grids. All those activities add some load that in combination lead to slowdowns.

-> dont try to pass things to first time visitors from the hypergrid during meetings. It seems there are some ways to trigger a complete inventory transfer for new visitors from outside (i.e. not having accounts locally). We had several occasions where i could see asset or inventory transactions on the console, going on for minutes, slowing the system. During the final minutes of the meeting we even had the sim stalled to a point that chat was blocked for several minutes. We will try to reproduce this in a test session. I hope that once the assets have been transfered it wont happen again. So we could use a mix of organizational measures to reduce that stress (dont do big inventory things during a meeting, try to trigger them before)

-> something builds up eating more and more cpu during such sessions, finally rendereing the system slow. When i restarted the server sunday morning it took about 5% cpu. As the first visitors came it this slowly started to grow to 15-20%. After the freebie area was filled with some things it never fell back below 30%. Something seems to have only partially manifested itself there (something non-existent blocking the path, it roughly felt like a larger copy of the hobo "ruins" that had been placed in one corner).
The server load continued to grow constantly, building up something in the "PhysFT" part of the stats.
At the end of the first session it barely dropped back below 100%. Durind the second session we permanently ran above 130%, ending in about 150%. When i inspected the system the next morning it was constantly at 200% (i.e. both cpu's running at 100%), the sim wasnt responding, i could not even shut it down gracefully.

Enough of that techy stuff now!
The meetings showed there is an interest in joining the hg1.5 realm, exploring new grounds.
Lets continue to explore and build this base into something useful for us all.

Preparing for the big event

as Pathfinder mentioned here: we will meet on the Hyperbase42 next sunday.
Time to clean up and test and fix some things...
Most of my gates dont seem to work anymore because the target grids have upgraded to 0.7.1 :(
Many destinations coming out of the Hypergate seem to have the very same issue :((
Since we will visit my beach house i have removed some non pg13 stuff ;-)

Vanish & i tried to set up a Hypertaxi between the Base and his TGIB Inn.
No matter what we tried we couldnt succeed getting the osTeleportAgent call to work (thew one that actually performs the teleport). I think it is due to this bug
( Fix osTeleportAgent for hypergrid destinations.)

Since this was fixed in opensim version 14351 (as opposed to the 13981 used in the Diva distro) i doubt it would make sense to try and backport that into the current Hyperbase42 installation.

So: no automagic transports, but "show-on-map-and-click-teleport".

So much to do, so little time ;-)
