#SL Mesh Deformer Update Week 41

by

The Mesh Deformer is in testing. Oz Linden still needs more test clothes to test with. While the first part of the Deformer is complete, a second part is just getting started.

The Deformer as is works. I think pretty well. That ‘deforming’ part is being tested. But, a part that was added to the Deformer is the base shapes feature. Currently we can select two base shapes for the Deformer to start its calculations from. But, we could have more base shapes because choice is really what Karl added in.

Possible Prototype for Deformer Upload

The only shapes that exist right now are the default female and male. Where are we going to get more? By making and uploading them. But, we can’t do that right now. That upload thing is the part that is in development now.

Darien Caldwell is currently working on that project. The repository branch https://bitbucket.org/oz_linden/viewer-storm-1716 is what Darin is forking for a starting point.

Viewer 3.4.x Problem

Oz Linden has given us some news on the crashing problem they have had with the Beta and Development viewer. The Lindens believe the current Beta viewer (3-4-1-265642) has the memory leak, or whatever, fixed. The crash rate is back to low rates.

For the techies, the problem had to do with how the cURL wrapper was threaded. The cURL thing has to do with computer network communication over networks. It is a programming library that makes it easier for programmers to implement communication protocols like HTTP and HTTPS. It helps with encrypting communications.

Wind Vectors Displayed – Red Lines

One more round of testing in the Beta viewer is in progress. Once completed the basic fix and changes will move to the main release viewer, likely next week (42).

It takes a couple of days of testing to collect enough data to make a determination on whether a fix is working or not. The current Beta Viewer was compiled on Saturday and released on Monday. If you have Auto-Update on, you got it before it was on the web site.

Internet Freedom to End in December 2012

by

I am a political activist. I don’t often write about politics on this site. But, a few things make it into this blog every now and then. This is one item that should make it in as it affects everyone on the planet.

Losing Freedom?

The nations of the world are negotiating the International Telecommunications Regulations treaty lead by Russia and China that will allow regulation of the Internet through the United Nations.  We know about the talks through a WCITLeaks anonymous posting by a participant in the talks.  The signing ceremony has been scheduled in Dubai in December of 2012.

It currently looks like Hamadoun Toure, From Mali and a graduate from the Russian Leningrad Institute and Moscow Technical University, is Vladimir Putin’s choice to run the Internet.

#SL Testers Needed Oct 11

by

Oskar Linden posted in the SL Forum requesting help testing some network changes. I suspect this is related to the Sudden Lag I’ve been writing about. See: Networking Optimization Pile On Test – October 11th

Linden Lab has made some changes to the way regions handle network traffic. We need your help to test. This will help us insure that regions are communicating appropriately over the network. Mainly we are concerned with agents entering via direct login, teleport, and region crossing. As well as other functions such as IMs, Voice, and Group chat.

Tomorrow, October 11th, at 4PM Pacific time (right after the server beta user group) we will conduct these tests with as many people as we have. Testing will take place on ADITI and require out of world communication we will be coordinating via IRC. This will require an IRC client connected to EFNET in the channel #sltest. If you don’t know how to do that you have until tomorrow afternoon to figure it out. 🙂

The details on the tests are here:

I hope you can come and help us test these new changes.

__Oskar

The test procedure is described in the SL Wiki. See: Networking Optimization Pile On Tests.

These tests will be on the ADITI grid.

#SL News 1 Week 41

by

There was a roll to the main channel this week. It seems to have gone well. At least all the regions get a restart after 3 weeks or so. The package was the one running on the Blue Steel RC Channel. It is a minor update and should have no visible effect on the simulator behavior. This is a release needed to enable a coming release.

Server & Scripting UG Oct 2012

Will get a new package. It will be the main channel code plus the changes to allow better use of the new hardware. Not knowing exactly what hardware the Lab is upgrading to… its hard to speculate on what the change may be. Presumably, if they are running Intel, they may be adding more threading features for the iCore series chips. If they run AMD, I have no clue.

Sudden Lag on the Radar

by

Toysoldier Thor has been relentlessly tracking down the causes of his in-world event crashes and sudden massive lag. Region owners and event managers have been collecting and providing data on the problem in the forum. See my previous article: New Lag Problem. See the forum thread here: Major Increase in Instant SIM LAG & Crash during large events.

Simon Linden acknowledged the effort and is starting to get people on the trail of the problem.  From Toysoldier:

From Simon Linden…
” Thanks for the reports, Toy … there’s some good information there that seems to shows the simulator getting into trouble when there are network problems. ”

I think now that we have a possible smoking gun… the LL staff can focus their investigation on the NETWORK.

Having more sim /region owners post the same performance statistics during one of these extreme lag events would help us further confirm the root cause.

If you are seeing this problem, read the thread and post the requested information from your occurrence of the event. Filing a JIRA works too.
