2025 week #31: SUG Leviathan Hour

TNC Commons, May 2025 – blog post

The following notes were taken from the Tuesday, July 29th, 2025 Simulator User Group (SUG) off-week meeting (which I’ll be referring to as the “SUG Leviathan Hour” going forward). These notes form a summary of the items discussed, and are not intended to be a full transcript. The notes were taken from my chat log of the meeting and Patera’s video, which is embedded at the end of this article – my thanks to her for providing it.

Meeting Overview

  • The Simulator User Group (also referred to by its older name of Server User Group) exists to provide an opportunity for discussion about simulator technology, bugs, and feature ideas is held every other Tuesday at 12:00 noon, SLT (holidays, etc., allowing), per the Second Life Public Calendar.
  • The “SUG Leviathan Hour” meetings are held on the Tuesdays which do not have a formal SUG meeting, and are chaired by Leviathan Linden. They are more brainstorming / general discussion sessions.
  • Meetings are held in text in-world, at this location.

Simulator Deployments

  • There are no planned deployments to any channels this week, only restarts.

In Brief

Also refer to the video for the full meeting.

  • Leviathan has turned his attention back to the issue of some people experiencing failures on logging-in, which he describes thus:
So… the problem is the login.cgi computes a big “viewer return value” (aka the VRV) which it sends back [to the viewer]. It has “Content-type: llsd+xml” header on it, and can be several MB in size. It contains, among other things, the list of your friends, groups, and a skeleton summary of all of your inventory folders. When the data package is very big and your download rate is low… it can take a while for it to arrive. If it takes too long the viewer can timeout on the request… even though login.cgi thought it “succeeded” and sent an alert to the Region where you were supposed to arrive.

– Leviathan Linden

Leviathan believe one aspect that makes the VRV so big is the number of folders within inventory (not the contents of folders, just the count of folders). However, Leviathan believes he has a solution (which is pending deployment):

So anyway: a relatively simple change on the login server allows the data to be gzipped, which can speed up the transmission … The Second Life Viewer (SLV) uses libcurl for its http requests, and it can handle gzipped data implicitly. Any viewer that picked up that capability from SLV should see benefits when login gets the update.

– Leviathan Linden

  • Another issue Leviathan is looking into a bug where Premium+ users can’t upload mesh for L$0 after crossing a region boundary, although he hasn’t found a root cause as yet.
  • There is apparently some exploratory work going on with in the engineering team(s) on the potential to use AI tools for code generation.
  • An update to SLua is in development, and might be deployed to Aditi (the beta grid) in the next week or so.
  • A general discussion on the (currently stalled) game_control project. As noted in my previous Leviathan Hour summary, the game_control work (and the work for a Linux version of the SL Viewer) is currently archived during the most recent switch to the viewer development and release workflow.
  • A Function to Detect Right click (which has it own debate) was raised. Leviathan Linden noted there subject is stalled. This led to an extended discussion on the ticket, and the issue(s) it encompasses. This discussion extended to one on Touch Pointer Capture, together with ideas for extended mouse hover operations, and expanded use of the mouse scroll wheel.

Date of Next Meetings

  • Formal SUG meeting: Tuesday, August 5th, 2025.
  • Leviathan Linden: Tuesday, August 26th, 2025, due to Leviathan being on vacation (unless he can find a volunteer to fill-in for him).

Lost Place of Norbu: a sub-tropical jewel in Second Life

Lost Place of Norbu, July 2025 – click any image for full size

Designed by Miri (SilentChloe), Lost Place of Norbu is located within a Homestead region and offers  a sub-tropical setting which fully lives up to the Tibetan meaning of its name – “jewel”.

The setting is presented as two islands set within an azure sea and sitting just off what appears to be a rugged and wooded coastal headland. The larger of the two islands is partially surrounded by a sandy beach, the sands of which also reach across the intervening shallows to brush against the smaller island.

Lost Place of Norbu, July 2025

Defined within its About Land description as a lost place near Taiwan, this adult-rated setting offers a lot to appreciate in a relatively small area (a good portion of the region being given over to sandy shallows); including places to sit and pass the time, assorted wildlife, and a partially hidden location that might easily be missed in a rushed visit.

The Landing Point sits on the north side of the region within the aforementioned shallows and facing the larger of the two islands. In appearance, this island almost has the look of a volcanic uprising about it; a tall peak rising from the sands to sit as a high plateau dominated by a huge headless, one-armed statue which may have once represented Buddha.

Densely canopied with the kind of foliage one might reasonably expect to see somewhere close to Taiwan (itself noted for its sub-topical evergreen forest), the bulk of the this peak – which put me in mind of the sold basalt core of a long-dead volcano – is hidden from the Landing Point by this green canopy, causing the eyes to be drawn to the shoulder of rock extending into the sea on the island’s on its north side and the single-storey wooden building standing upon it.

Reached via a set of stone steps rising from the beach between two lines of bamboo trees, the build mixes places to sit, enjoy Japanese tea or engage in Adult activities, its cool interior.

Behind it, meanwhile, a path arcs around the eastern side of the main peak, travelling through a small Zen garden and under a Torii gate to reach a southern shelf of rock extending out over the southern waters. Another, stone Buddha, small than the one on the island’s peak and semi-clothed in moss, sits within a stream of water running outward across this rock shelf and fed by a waterfall at its inland end, and which drops into the waters below at its outer end. A simple wooden boardwalk crosses this stream, allowing visitors to follow the path onwards, and so circumnavigate the island’s peak and return down the stone steps back to the beach.

As the sands of the beach do not fully encircle the island, it is impossible to use them as a similar means of circumnavigation, but follow them west and then around to the south from the landing point, and you’ll find yourself passing under the shelf of rock where “little Buddha” sits, then onwards to the island’s hidden gem.

Guarded by a mix of tall pagoda-like lamps and a Torii gate, all of which stand ankle-deep in lilies and other greenery happy to grow in the shallows, together with hovering water lily lanterns, sits the Shibari House.

Almost entirely hidden from view from above thanks to the rain forest canopy, the name of this place might sound like it is a centre for Adult activities. However, whilst such activities are possible, unless in actual use during a visit, they and cleverly hidden away, allowing the place to apparently take its name from the artwork mounted on the walls of the open-air rotunda.

Lost Place of Norbu, July 2025

Across the sandy shallows and tucked into the south-west corner of the region, the smaller of the two islands is equally as rugged as the larger and well canopied by sub-tropical foliage. A little harder to get around, it offers numerous places both beach-side and up among the rocks of s backbone to sit and pass the time, including an onsen watched over by egrets and with its outer ring of water patrolled by large koi carp.

If the onsen is not to your liking, then there is a waterside gazebo where it is possible to keep an eye on the location’s three elephants. I’m not sure how they found their way here, but they appear to be enjoying wading around in the warm waters, whilst colourful birds circle overhead. Some of the latter appear to appreciate the presence of a Japanese dragon fountain as it dribbles water from a rocky outcrop part-way up the side of the island. It sits close to another little retreat overlooking the Onsen, but I confess I had to resort sitting on the couch within it in order to reach , as I couldn’t find a path up to it.

It is in several of the couches, chairs and sit points in general that the setting’s more adult nature can be found, rather than in anything overtly displayed; thus, there is nothing within Norbu that might offend the sensitive when visiting. Rather, this is a peaceful setting which genuinely offers a lot to see, appreciate and to photograph.

Finished with a (perhaps too) subtle soundscape and presented within an appropriate EEP setting, Norbu offers an engaging fusion of ideas: a sub-tropical island off the coast of Taiwan but with a strong Japanese influence, wandering elephants, and even a little puffin enjoying a little bit of a tropical vacation. As such, it is well-worth the time taken to visit it.
