SL Scripters / creators: LSL XML-RPC shut-down

via Linden Lab

Further to comments passed at the March 21st Simulator User Group, Signal Linden has formally announced the shutting-down of the LSL XML-RPC functionality.

A method for enabling communication between remote systems and LSL scripts, LSL XML-RPC has been deprecated since the introduction of HTTP-In back in 2009. As noted at the SUG meeting and again in Signal’s post, requests using LSL XML-RPC have dwindled to just a few dozen requests per hour.

As a result:

  • Rather than use development resources into maintaining it, LL would prefer to focus their resources on developing new features.
  • Recommend that those users / creators with functionality that depends on XML-RPC, migrate your scripts and supporting services to the more secure HTTP-In.

To allow time for those still using LSL XML-RPC to ensure their scripts are properly migrate their scripts, and to ensure there are no services users may have forgotten about and which might otherwise break if LSL XML-RPC were simply shut-down, the following time frame for the terminating use of the functionality.

  • April-May 2023: one or more unannounced circuit-breaker exercises will be performed by temporarily blocking incoming LSL XML-RPC traffic. This will give residents and Lindens a chance to experience XML-RPC shutdown and perform any required corrective actions (Upgrading scripts to HTTP-In, etc.) before permanent shut down.
  • June 1st, 2023: incoming LSL XML-RPC traffic will be permanently blocked.

For further information, please refer to Signal’s blog post. Questions / concerns about this move can be raised at any Simulator User Group meeting. These are held every Tuesday at 12:00 noon SLT, at Simon Linden’s meeting place. I will also update status in my weekly SUG summaries.




The VWBPE 2023 conference in Second Life


The 2023 Virtual Worlds Best Practice in Education (VWBPE) conference takes place between Thursday, March 23rd and Saturday March 25th, 2023 inclusive. A grass-roots community event focusing on education in immersive virtual environments, VWBPE attracts 2200-3500 educational professionals from around the world each year. It’s primary goals are to foster discussion on, and learning about educational opportunities presented through the use of such virtual spaces, a defining core values and best practices in doing so, including:

  • Helping to build community through extension of learning best practices to practical application of those ideas and techniques;
  • Providing networking opportunities for educators and the communities that help support education; and
  • Offering access to current innovations, trends, ideas, case studies, and other best practices for educators and the communities that help support education.

In the context of the conference, a “virtual environment” is an on-line community through which users can interact with one another and use and create ideas irrespective of time and space. As such, typical examples include Second Life, OpenSimulator, Unity, World of Warcraft, Eve Online, and so on, as well as Facebook, LinkedIn, Twitter, Pinterest or any virtual environments characterised by an open social presence and in which the direction of the platform’s evolution is manifest in the community.

Each year, the event has a central theme, which for 2023 the organisers describe thus:

Our theme for the VWBPE 2023 conference explores the concepts behind our Uncommon Realities. Learning from each other’s perspectives in how we visualize challenges, the skills we bring to bear in working through alternatives, prototyping solutions, and the personal meaning we find in interpreting the results of our efforts.
We face unparalleled challenges in the world today. Embracing our uncommon realities can be a source of inspiration to bring people together. To tell our own stories. To show people our strengths. And to inspire others to not be afraid of being different. More importantly, it allows us to explore a profusion of ideas we may never have thought of if not for our willingness to share and be seen.

– From the introduction to VWBPE 2023

WWBPE Wetlands Visitor Centre

Region Themes and Facilities

For 2023, the conference returns from space, where it has been for the past couple of years, to a more Earthly setting, presenting a series of biomes in which events will be held and people can explore and play. These comprise:

  • Canopy Biome (Canopy Point): a canopy biome is a forestry ecosystem characterised by a dense layer of vegetation at the top (the canopy), under which can be found a diverse forest ecosystem.
  • Rainbow Basin: an ecosystem found within a basin or depression within the Earth’s surface, often characterised by wetlands, rivers, lakes, with the environment ranging from dry through to very wet.
  • Jungle Habitat: a tropical forest environment generally characterised by high levels of rainfall and warm, humid temperatures. These are often among the most biodiverse ecosystems on the planet.
  • Meadow Biome (Floating Meadows): a meadow biome is characterised by a mix of forest and meadow habitats, generally in temperate zones with moderate temperatures and rainfall.

The four regions form a square and feature the main auditorium straddling there adjoining corners. They are supported by:

  • Grasslands Biome – home to the VWBPE Gateway.
  • Badlands Biome (Badlands Wild): badlands are characterised by their rugged, eroded landscape, featuring ravines, canyons and buttes. They tend to be semi-arid in nature. Here they are also home to the Rock Theatre Workshop.
  • Wetlands Marsh: an ecosystem characterised by a combination of shallow water, emergent vegetation and saturated soils. Here they are also home to several of the VWBPE social venues.
  • Desert Hinterlands: a region receiving very little rainfall, resulting in a dry, arid environment, often with high daytime temperatures and very low night temperatures. Home to the Oasis Lecture Theatre and The Ruins Workshop.
  • Tundra Expanse: a cold, treeless biome form in the Arctic and Antarctic regions, characterised by low temperatures, strong winds and little precipitation and vegetation limited to shrubs, mosses, lichens and the like, the ground being generally frozen. Home to the Quadrivium and the Hearth Lecture Theatre.

The VWBPE Gateway

At the VWBPE Gateway you can find information on the conference – including the schedule for the day, a Swag Bag which includes the conference teleport HUD for easy access to all locations and venues, information on the biomes comprising the conference regions, and more. And, of course, VWBPE volunteers are on hand to answer your questions!

Core Facilities and Locations

Within these regions the following core facilities for the conference can be found – but please refer to your conference Swag Bag (and teleport HUD!) for full  information on all locations and facilities at this year’s conference.

The Teleport HUD

As noted above, the VWBPE teleport HUD is the best way of getting around the facilities. It can be obtained via the Swag Bag giver at the VWBPE Gateway and is delivered to inventory in a folder. Open the folder and right-click → ADD the HUD. Note that you will need to grant teleport permissions for it to work.

VWBPE 2023 – Teleport HUD

By default, the teleport HUD attaches to the bottom left of the viewer window, with a single button – SHOW – available. Clicking this will expand the HUD to show:

  • Buttons for teleport to venues and locations within the conference regions. Click on these will either teleport you directly to the destination (Gateway and Lest We Forget), or open a sub-menu of destination options (e.g. Auditorium access points, talks and presentations venues, etc.).
    • Note that after being teleported to a location, the HUD will automatically minimise itself.
  • Four buttons to the right: visit the VWBPE website (VWBPE logo button); MAIN – return to the main set of teleport option buttons; HELP – receive a note card on how to use the HUD; HIDE – minimise the HUD.
