2020 Simulator User Group week #29 summary

The Empire of Dreaming Books, May 2020 – blog post

The following notes were taken during the Simulator User Group meeting of Tuesday, July 14th, 2020.

Simulator Deployments

Please refer to the server deployment thread for news and updates:

  • On Tuesday, July 14th, the majority of the grid was updated with server release 544419, first deployed to the RC channels on Wednesday, July 8th. This should resolve issues with off-line inventory offers and group notice attachments, although a viewer-side update is also required, which is in the current Arrack RC viewer.
  • On Wednesday, July 15th, the RC channels should be updated with server maintenance update 544832, designed to resolve issues with some internal service updates, chat range improvements and capability improvements.

SL Viewer

There have been no official viewer updates to mark the start of the week, leaving the current pipelines as follows:

  • Current Release viewer version, dated June 11, promoted June 23, formerly the CEF RC viewer – No Change.
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):
  • Project viewers:
    • Custom Key Mappings project viewer, version, June 30.
    • Mesh uploader project viewer, version, June 11.
    • Copy / Paste viewer, version, December 9, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version, November 22, 2019.

    • 360 Snapshot project viewer, version, July 16, 2019.

Cloud Uplift

I don’t know if any of you have looked at AWS, but it’s a huge and complex system, so the learning curve on how to build servers, get them deployed, set up networks, security, etc etc etc is pretty tough … Not a surprise, just a lot of learning and work.

Two publicly-accessible regions  – Morris and Ahern – on Aditi (the beta grid) are now running in the cloud. Aside from outbound HTTP messaging and e-mail, they should function with no discernible difference to regions within the Lab’s co-lo facility.

Commenting on the HTTP messaging / e-mail situation, Oz Linden stated:

There are abuse constraints in AWS that we need to make sure we don’t violate. Both outbound HTTP and Email are ways that scripts could cause problems. We have a way to regulate HTTP out that we’re pretty sure of, and which you should be able to test fairly soon on main grid simulators. llEmail may get some new constraints and/or more severe throttles … still studying that one. When we have some updates on that, we’ll post in the LSL forum.

– Oz Linden, SUG Meeting, July 14th

It is believed that the current HTTP / e-mail out issues should not affect HTTP / e-mail between regions. The issue also shouldn’t affect llTargetedEmail, since the caller cannot specify an arbitrary email address.
