Sitting in The Middle of Nowhere in Second Life

The Middle of Nowhere, November 2023 – click any image for full size

Life in the physical world is just a little too hectic; with the house now approaching its 30th birthday (not that I’ve lived in it that long!) the decision was made earlier this year to start overhauling and updating parts of it. You know, the usual stuff: new kitchen and other rooms, interior alterations to make better use of space, bathroom updates, blah, blah, blah. Some – like the installation of a full solar / battery system – have gone well (aside from a few software teething troubles); others have not progressed quite so well, leading to much gnashing of teeth and trying very hard not to teach the cats too many Naughty Words (they are both approaching 15 months of age, so far too young for some of the more colourful metaphors which bless the English language!).

All of which means that there are times (quite a lot of them of late) where the urge to just get any from everything has been overwhelming. Fortunately for me – and anyone feeling the need to escape the day’s demands and just breathe in nature – Ari (Aridis Inaka) has provided an escape to – quite literally – The Middle of Nowhere.

The Middle of Nowhere, November 2023

Occupying a Homestead region, this is a setting where the simple pleasures of country walks, feeling tall grass brushing against fingertips as you wander and watching birds wheel overhead and horses roaming free, can be enjoyed. A place which, despite the surrounding sea, gives a sense of gently rolling prairielands only lightly touched by the hand of Man; a setting where (for those who wish) a gentle audio stream flows to further encourage muscles to unknot and thought processes to let go (and I’ll be honest, given it features the likes of Bear McCreary, Danny Elfman, Alexandre Desplat and legends such as Ennio Morricone and Michel Legrand, it really is worth a listen!).

The region’s About Land notes introduce the region as place of horses and sunsets and where light role-play is welcome. It is a description that fits, although there is much in terms of opportunities for photography, relaxation and contemplation that perhaps passes unmentioned. It’s also a place well suited to the quote from Frances Jane van Alstyne’s (aka Franny Crosby), On Hearing a Description of a Prairie Ari offers as a description for the region within her Profile:

Oh! could I see as thou hast seen,
   The garden of the west,
When Spring in all her loveliness
   Fair nature’s face has dressed.
The rolling prairie, vast and wild!
   It hath a charm for me—
Its tall grass waving to the breeze,
   Like billows on the sea.
The Middle of Nowhere, November 2023

It’s a fitting description because the American prairie can often been imagined as a vast ocean as the wind ripples the grasslands (and crops!) growing across them like waves caught in the breath of a sea breeze. More to the point here, perhaps, is that the metaphorical mixing of prairie and sea also helps region and surrounding waters flow together as a unified environment, rather than one simply being bounded on all sides by the other.

To offer a blow-by-blow tour of the region is perhaps an exercise in futility; its very nature – almost completely low-lying and carpeted in tall grasses – means that it offers most of its secrets to visitors from the moment they arrive. Points of interest are easily located, and the setting’s easy beauty sets the feet a-wandering with ease. The only real break in the gentle undulations of the land are to be found to the north, where a curtain of high cliffs rise from a westward and squat table of rock to border the region as they march to the east, the waters tumbling from them giving rise to a shallow channel which in part separates them from the rest of the landscape.

The Middle of Nowhere, November 2023

The grasslands are largely given over to the horses roaming them, although here and there the horizon is broken by a tree or by the blocky form of a wooden shack or cabin – or ruin thereof. The trees offer a mix of shade for visitors and horses and places to sit or swing. The shacks and cabins speak to the passage of human occupation, as little as it might have been, what appears to be the detritus of that life remaining within and without some of them – thus offering possible props and ideas for gentle role-play. To one side of the setting and atop a small knoll, sits an aging chapel, a small graveyard in the lee of the knoll. The chapel offers a sanctuary of remembrance to those wishing to avail themselves of it, whiles the open camp site a short walk away presents a place for fireside conviviality.

Simply formed, but clearly put together with an eye for detail (and a little whimsy, giving the wandering / dancing tree!), this is a region which can be easily enjoyed and photographed. If you are looking for a place to which you might escape the demands of life (physical or virtual) and simply gather your breath whilst recharging mental batteries, then you can do little better then dropping into The Middle of Nowhere.

2023 SL SUG meetings week #44 summary

Posted on by Inara Pey
Grauland, August 2023 – blog post †

The following notes were taken from the Tuesday, October 31st Simulator User Group (SUG) meeting. They form a summary of the items discussed, and is not intended to be a full transcript. My thanks to Yuzuru Jewell for the meeting transcript – for once, clock changes caught me off-guard, and I missed the greater part of the meeting!

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.
  • These meetings are conducted (as a rule):
  • They are open to anyone with a concern / interest in the above topics, and form one of a series of regular / semi-regular User Group meetings conducted by Linden Lab.
  • Dates and times of all current meetings can be found on the Second Life Public Calendar, and descriptions of meetings are defined on the SL wiki.

Server Deployments

  • No deployments for SLS Main channel, but the simhosts were restarted.
  • On Wednesday, November 1st the BlueSteel and LeTigre will receive the simulator support for PBR Materials.
    • Please remember: if you have anything that uses PBR materials and you rez that object (or wear it) on a non-PBR simulator,  the PBR Materials will be stripped from the object and forgotten.

Viewer Updates

No updates to viewers for the start of the week, leaving the official viewer pipelines as:

  • Github Actions (GHA) RC viewer, version 6.6.16.6566955269, issued October 20 (with major CEF update and number version numbering) and promoted on October 25.
  • 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:

Games Controller Update

  • Leviathan Linden is having issues getting the viewer to build for Mac.
  • He hopes to have support for arbitrary controllers before this is shippable in the viewer, Which means some way to remap keys and axes.
  • The server-side code has been largely settled for any initial release, although there are some questions about whether some LSL constant names will be added for the various buttons and axes.
  • The documentation for the Game Controller SL event can be found with the SL wiki.
  • A projects viewer is available via Github actions, but per the above, simulator support is pending the Fall Colours RC release.
  • Pending main grid availability, the simulator support is available on Aditi (the Beta grid) within the following regions: Ahern, Cloud Sandbox 3, Cloud Sandbox 4, Mesh Sandbox 2, Sandbox Wanderton, Snark, and Tyl.

SL Combat

  • Rider Linden noted that LL will likely start a “Combat Committee” in early 2024 (presumably a new User Group meeting).
  • He will endeavour to put a strawman put together in terms of what might be addressed and the broad scope of changes which could be implemented ahead of any meetings. Currently, he is investigating the number of combat systems within SL.
  • However, what his is currently considering is an “on_damage() event, which he defines thus:
On damage-enabled regions that event would be called rather than the system simply applying damage. That would allow the combat system to make modifications to the damage (e.g. fire resistance, armour, etc) That event could then apply the damage to the avatar it was attached to. My goal for this project is to provide the tools to build combat systems. Not proscribe one to fit all situations.  
  • This idea received broadly positive feedback from the combat enthusiasts attending the meeting, with the caveat that the event must be able to report any damage source, to allow for moderation where there are differences of opinion over things like hits received.
  • Further suggestions for this idea and combat in general included:
    • on_damage(): the LL damage system should work as a “fallback”,  so people don’t require an attachment.
    • on_damage(): estates should be able to configure “minimum” and “maximum” damage hit limits to prevent people trying to game things via scripted means (e.g. using a scripted attachment to prevent taking any damage at all or weapons which “instakill” all the time).
    • A further request for a capability such as BUG-6707, “[Experience Tools] Feature Request – Parcel/region setting to allow/disallow non-experience scripts”, which  – for combat regions using SL Experiences – could do much to negate scripted means of trying to “cheat” per the above bullet point.
    • An update to the the rez with parameters event to allow those engaged in combat to be able to instantly swap weapons without having to attach all the weapons they might require ahead of entered a combat game.
    • Enabling region owners to set the response to “dying” in combat (/games in general) – such as a flag which allows the “dead” to be teleported to a specific location (e.g. a specific spawn point” or the region / parcel’s landing point), together with a “respawn cooldown” period (e.g. players being respawned receive no damage for a given period of time – preventing someone just taking up shop near a respawn point and picking people off as soon as they arrive).
    • A request for a capability such as BUG-233175 “llSetAgentParams: a way to customize certain agent attributes” – this would not only have general applications (e.g. those outlined in the Jira), it might potentially allow things like the avatar hitbox to resize in accordance with the avatar size.
  • Intermixed with this was a broader discussion both related to and separate from combat in SL, including scripted object collisions (raised specifically with issues of vehicle use and region crossings / striking banlines (e.g. see BUG227303), but which can also impact combat play in SL – e.g. by shutting down worn combat meters on region crossing).
  • As Rider noted, is is still putting together a strawman specification as to what might be considered as having potential to be addressed, scope of possible changes etc., doubtless with at least some of what was discussed in the meeting feeding into it, as he continues to visit combat regions and investigate the current systems in use, etc. As such, this will likely become a more focused discussion once any such “Combat User Group” is up and running.

In Brief

  • It has been noted that on the current PBR RC viewer, texture LOD has apparently changed, breaking the majority of on prim boards at a distance over 20m, and leaving the only way to get clear text on objects such as a sports scoring board is by using individual font character text per face rather than font map/atlas. This issue appears to be awaiting a Jira.

Artistic digital fusions in motion in Second Life

Posted on by Inara Pey
Kondor Arts Centre, November 2023: Monique Beebe – On the Move

I confess that I find myself caught in a dichotomy of viewpoints when it comes to AI art; on the one hand, there is a huge potential for using AI tools to enhance the creative process and allow the artist to produce some truly stunning and innovative art. Countering this are the twin concerns of the potential for AI tools to be terribly degenerative towards genuine artistic skills under the guise of “democratising art for all”, and the fact that very often – as with Midjourney, the current darling of art AI proponents – those behind such tools are content to raise a large middle finger towards concerns of copyright & artists’ rights as they pull “source” material from wherever they deem fit.

As a result, I’ve tended to exercise caution in reviewing exhibitions of AI art in Second Life. Not that I deem it unworthy or have doubt towards the artists concerned; rather, it is the fact that it is not always easy to identify the broader provenance for such art in terms of a potential for it to incorporate elements which might be regarded as violating the copyright of others. Fortunately, there are artists and exhibitions with SL utilising AI where the provenance for the pieces lays so clearly with the artist’s imagination and skill, they can be seen and enjoyed entirely in their own right and without the broader questions surrounding the use of AI intruding.

Kondor Arts Centre, November 2023: Monique Beebe – On the Move

Such is the case – once again – with the work of Monique Beebe, who recently opened On the Move at the recently relocated Kondor Art Centre, operated and curated by Hermes Kondor.

On the Move is not just an exhibition; it’s a leap into a new era of artistic expression. Whether you’re a connoisseur of art and technology, a futurist, or simply an admirer of the creative process, this exhibition promises to leave you spellbound and questioning the limits of human and AI collaboration. … An exhibition that pushes the boundaries of creativity through the fusion of MidJourney AI, cutting-edge Gen2 MP4 technology.

This might sound a grandiose statement as the official introduction to On the Move, but I guarantee you it is not. I’ll also guarantee that the still images provided here do not come close to the beauty and creativity found within each of the collection’s images, every one of which is imbued with a richness of motion and life founded on Monique’s own creative eye and ability to capture thought, emotion and humanity.

Kondor Arts Centre, November 2023: Monique Beebe – On the Move

As I’ve frequently noted in covering her work, Monique – or Moni to her friends – is one of the most gifted individuals to enter the Second Life art world; an artist whose expressiveness is utterly captivating and who is herself wholly captivated with the creative process. She had been active in Second Life for nigh-on a decade prior to her first public exhibition in February 2017 – an exhibition which came about thanks to the gentle and considered encouragement from Dido Haas, taking place at her Nitroglobus Roof Gallery. Avatar-centric, it was an exhibition which immediately captivated me (see: Hidden Faces in Second Life), and led me to becoming a keen follower of Moni’s work over the intervening years.

Indeed, following Moni’s evolving expressiveness, her ability to challenge herself by constantly evolving her technique and style, the manner in which she has driven headlong into a variety of creative processes – photography, art, digital recording – all the while refining her abilities and extending her craft, has for me been an utter delight. Her desire to learn, to grow her art and cultivate new skills towards that end has led to a series of exhibitions startling in their beauty and emotional content, and which just under a year ago saw her present her first exhibition utilising AI tools, also at the Kondor Art Centre (see: Monsters, Demons and Chess in Second Life).

Kondor Arts Centre, November 2023: Monique Beebe – On the Move

As per its own introduction, On the Move once again utilises AI (MidJourney), with Moni combining its algorithmic power with still images, video and animations to produce 14 looping images-in-motion; a veritable tour de force in a mastery of digital techniques and incredible expressions of beauty and artistry which transports us instantly into the worlds of Moni’s imagination and creative expressiveness.

From the simple turn of a (Tilda Swinton-esque) head and slow blink of eyes (Eyes are mirror of the soul) to the utterly enthralling Where the magic begins, these are pieces which honestly sit well above the ability of mere words to encompass. Each is a visual essay in its own right – but more to the point, it is in their motion that their emotional depth resides, each one pulling us towards its narrative and passional core; as such, they really should be seen first-hand. Further, they collectively stand as a triumphal validation of the multiple hours of learning, trial, error and perfection of technique that have enabled Moni to offer art which is both truly representative of the positive potential of AI and digital capabilities as the tools (rather than the subsummation) of genuine artistic expression and creativity.

Space Sunday: Jovian Moons, and lunar aspirations

Posted on by Inara Pey

We’re probably all familiar with the concept of some Moons within our solar system  – notably Saturn’s Enceladus, and Jupiter’s Europa, Ganymede and Callisto – potentially being completely encompassed by a liquid water (or at least a slushy) ocean under their surfaces. But how about a moon being almost completely encompassed by an ocean of hot volcanic magma just a few kilometres under its surface?

That’s the proposal contained within a new paper written under the auspices of NASA’s Jet Propulsion Laboratory, and based on an analysis of data obtained by the Jovial Infrared Auroral Mapper (JIRAM) instrument aboard NASA’s Juno mission in reference to Io, the innermost of the four Galilean moons of Jupiter.

Of course, we’ve long known that Io, a moon slightly larger than our own, is the most volcanic place in the solar system. More than 400 active volcanoes have been identified since we first witnessed one erupting in 1979, courtesy of NASA’s by Voyager 1 in 1979, and the Juno mission has imaged no fewer than 266 actively erupting during its periodic fly-bys of Io as it studies Jupiter and its moons. The overall driving force behind these volcanoes is tidal flexing deep within Io’s core and mantle, the results of the moon being in a constant state of flux thanks to the gravitational influences of (most particularly) Jupiter to one side and the three other Galilean satellites on the other.

However, there has always been something of a question as to how these volcanoes might – or might not – be related and directly powered. Here on Earth, volcanism usually occurs as a result of decompression melting within the asthenosphere – the upper limits of the mantle directly under the lithosphere/crust comprising solid and partially-melted rock. This gives rise to magma, which is then forced upwards through the lithosphere as localised volcanic eruptions. This was long held to be the case with Io, with scientists believing its volcanoes, like the majority on Earth, were driven by the upwelling of individual magma flows.

But during the Galileo spacecraft’s observations of Io between 1995 and 2003, the data gave tantalising hints that Io’s volcanism could be the result of a somewhat different process, but it has taken the unique capabilities of the Juno spacecraft to confirm this to be the case. By gathering extensive thermal and infrared imaging of Io’s mantle, the JIRAM instrument has been able to put together a comprehensive view of the upper layers of Io’s mantle, revealing that far from being a layer mix of solid and partially melted rock, Io’s asthenospheric region is entirely molten in nature.

In other words, lying just below Io’s lithosphere (roughly 12-40 km thick) is a moon-girdling ocean of magma, some 50 km thick, with a mean temperature of some 1,200ºC, and which powers all of Io’s active volcanoes.

This may not sound exciting in the scheme of things, but it further demonstrates the uniqueness and complexity to be found within the Jovian system.

A further example of this can be found with Io’s big brother, Ganymede. The third of the Galilean moons in terms of distance from Jupiter, Ganymede is not only the biggest of the Galilean moons orbiting Jupiter, it is the biggest and most massive natural satellite in the solar system. In fact, if it were orbiting the Sun rather than Jupiter, it would be classified as a planet, being even larger than Mercury.

Ganymede, like its smaller siblings around Jupiter – and the rocky planets of the inner solar system – is a complex place enjoying a complicated relationship with its parent; one which shares near-similarities with Earth’s relationship to the Sun.

Much has long been known about Ganymede as a result of observations made from Earth – such as via the Hubble Space Telescope – and by the various missions which have flown past or orbited Jupiter. These have helped us confirm that Ganymede has a sufficiently warm interior to support a global liquid water ocean beneath its crust, an ocean larger by volume than all of Earth’s combined.

We’ve also been able to (largely) confirm the presence of a tenuous atmosphere of oxygen and CO2, which seems to be particularly concentrated around the northern and southern latitudes, likely constrained by the interaction between Ganymede’s weak magnetic field and the far more powerful magnetic field generated by Jupiter – the predominant O2 content of the atmosphere is thought to be the result of water vapour escaping the moon’s interior being spilt by the radiation carried down over the poles by the magnetic field interaction.

It is this interaction between radiation, magnetic fields and the surface of Ganymede which have been part of the focus of a study made of the moon using instruments on the James Webb Space Telescope (JWST), and which was recently published.

Ganymede’s surface is dominated by two types of terrain: bright, icy features with grooves, covering about two-thirds of Ganymede’s surface, and older, well-cratered and darker regions )on places scored by asteroid impacts of the moon’s more “recent” past, which could not be confused with the brighter terrain) . The two terrain types are not differentiated in terms of their location on Ganymede’s surface, they are instead intermingled, with the lighter terrain cutting swathes across the darker terrain.

Some of these brighter swathes – notably those around the Polar Regions – carry strong evidence of water ice, which appears to have been exposed by (in the words of the study) “the combination of micro-meteoroid gardening, excavating the ice, and ion irradiation”.

In other words, over the millennia, dust and material has been caught within the interactions between the two magnetic fields, smashing into the moon’s surface to expose the underlying water ice, allowing it to be irradiated by plasma also carried by the inflowing magnetic field, causing some of it to escape as water vapour which has been either further irradiated and broken down (thus giving rise to the accumulation of the tenuous, O2-rich atmosphere near the surface), or re-accreting as easily-identified water ice on the surface rock.

Whilst the two magnetic fields interact around Ganymede’s poles and along the moon’s “trailing edge” as it orbits Jupiter in a very similar manner to the interaction between Earth’s magnetic field and that of the Sun over our own poles, the spectral properties seen along the moon’s ”leading edge” in its orbit suggest that there is a far more complex, and yet to be understood interaction taking place between the magnetic fields of planet and satellite. Solving this mystery might require time – and some assistance in the form of the European Space Agency’s Jupiter Icy Moons Explorer (JUICE) mission launched in April 2023, and due to reach the Jovian system in 2031, where it will likely uncover more surprises about both Ganymede and Europa.

2023 week #43: SL TPVD meeting summary

Posted on by Inara Pey
Goatswood, August 2023, blog post †

The following notes were taken from my chat log transcript and audio recording of the Third Party Viewer Developer (TPVD) meeting held on Friday, October 27th, 2023. Afraid no video for this month, Pantera has a lot going on.

Meeting Overview

  • The TPV Developer meeting provides an opportunity for discussion about the development of, and features for, the Second Life viewer, and for Linden Lab viewer developers and third-party viewer (TPV) / open-source code contributors to discuss general viewer development.
  • As a rule, these meetings are:
    • Generally held once a month  the third or fourth Friday, at 13:00 SLT at the Hippotropolis Theatre. See the SL Public Calendar for specific meeting dates.
    • Open to all with an interest in viewer development.
    • Conducted in a mix of text and voice.
  • The notes herein are drawn from a mix of my own chat log and audio recording of the meeting, and are not intended to be a full transcript.

Viewer Updates

The Github Actions (GHA) RC viewer, version 6.6.16.6566955269 was promoted to de facto release status on October 25th. This marks the first release viewer built using the Github Actions (indicated by the extended version number). This viewer also includes a significant update to the Chrome Embedded Framework (CEF) for media handling.

The rest of the current crop of official viewers remains as:

  • Release channel cohorts:
  • Project viewers:

General Viewer Notes:

  • Upcoming official viewer can be viewed on the Github Actions build page, so what is coming down the line can be seen; however artefacts within the list are not publicly linked to downloadable items such as installers. This may change in the future.
  • The Emoji RC viewer is defined as being “in test”, with the other RC viewers in a maintenance cycle to gain parity with the new release viewer.

PBR Materials Update

  • The back-end support for PBR Materials is liable to be deployed to both the BlueSteel and LeTigre RC channels (so approx 3,000 regions) in week #44 (commencing Monday, October 30th), pending the code clearing QA.
  • Core work remains in “maintenance mode” with bug fixing and a focus on driving the project forward towards release.
    • It is believed the only significant blockers remaining are those of performance issues on the Mac version of the viewer – and LL are happy to take suggestions from TPV developers on how to get the Mac variant of OpenGL perform better.
  • One additional issue which had been reported was that of non-PBR enabled viewers appearing to suffer high pack losses on PBR regions (BUG-234550). However:
    • Investigations appear to have shown this as being a “sensor ghost” – the viewer reporting messages it receives but which are not in its message template (a would be the case with a non-PBR viewer receiving PBR specific messages) as a packet loss, which is not really accurate.
    • To deal with the specific issue with non-PBR viewers on PBR regions, and as an interim measure until the PBR viewer is the de facto release viewer, the updated message template for the PBR viewer is to be incorporated into the current RC viewers, together with a suppressor to prevent non-PBR viewer generating false packet loss updates. The code will then be available to all official “pre-PBR” viewers as they are updated with the RC code.
    • TPVs wishing also wishing to eliminate the false reporting of packet loss in their non-PBR viewer releases are encouraged to also pull the PBR viewer message template commit from Github and incorporate it in any upcoming pre-PBR updates they may have in the works.
  • Overall, and allowing for any list-minute issues + clearing the Mac viewer issues, the plan is to pretty much release PBR Materials on the basis of what is currently incorporated in the simulator code and the current RC viewer.
    • This means there will be a range of known issues within the release; however, it is believed that none of them will break any existing content on the Main grid, nor will any fixes for them which are introduced following the initial release.
  • One of the outcomes of the glTF  / PBR project has been a closing of the “divide” between the simulator and viewer engineering teams, with people working on both sides as the PBR project has progressed. This will continue through further iterations of glTF support (e.g. through elements such as the Interest List, which is both viewer-side and simulator-side, and which is not currently geared towards optimal handling scene-wide updates, as will be required as additional aspects of the glTF specification are incorporated into SL).

In Brief

  • There was a general discussion on the internals of viewer development (general message handling, viewer asset throttling, location of “official” masters of things like the message template, the status of the Lab’s Libcurl implementation in light of recent libcurl security issues (in short: “stuck” on an earlier version, so not directly affected), HTTP2 vs. HTTP3 updates,  etc.).
  • A general commentary on Windows 32-bit usage (not no longer officially supported) – with Firestorm stats reporting around 1.9% of their user base still appear to be running 32-bit windows – but the majority of this figure might be down to an Intel bug reporting 64-bit users running 32-bit.
  • A general discussion on the viewer + time-zones, providing a means to add the day of the week to the viewer log-in screen, rather than those in time zones other than California have to check the local day via the viewer clock tool-tip once logged-in.
    • In this, the fact that the time reported in the viewer is “PDT” (and/or PST? I’ve never actually noticed if the viewer reflects changes between PDT and PST notation) rather than “SLT” – which is the acronym everyone in SL understands – can also be a source of confusion. As can the fact that elsewhere within Second Life properties UTC (GMT) can be used.
    • during the discussion it was indicated that LL will likely try to be more consistent in referencing SLT rather than physical-world time zones.
  • Reference was made to a forum discussion on event message polling (particularly viewer side region start-up) which can have an impact (/unintended consequence) in terms of things like message execution. Monty Linden is involved in these discussions and in investigations, and improvements will be appearing in upcoming simulator releases.
  • The above led to a general conversation on reliable SL documentation sources (the broad answer in case of technical documentation being “the code”), and the historic reasons for public-facing documentation becoming fragmented (e.g. the old issue of SL wiki pages being repeatedly vandalised & so locked from editing by users who might otherwise be well-placed to update them), etc.
