2020 SUG meeting week #51

Solus, October 2020 – blog post

The following notes were taken from the Tuesday, December 15th Simulator User Group (SUG) meeting.

Server Updates

Deployments in week #50 got a little confusing, with both SLS (Main) and some RC (Magnum) RC channel servers updated to release 553685, with the remainder of the simulators being updated to the same release on  Tuesday, December 15th. At the SUG, Rider linden explained the situation thus:

 So let’s see. We ended up having one extra set of rolls on Friday and then again today to catch the last of the stragglers. It was basically just an internal configuration change to help support uplift. I’m confident that that was the final roll of the year.

SL Viewer

The Dawa maintenance viewer updated to version 6.4.12.553723 on December 15th. The rest of the current crop of official viewers, remain as follows:

  • Current release viewer version 6.4.11.551711, formerly Cachaça Maintenance RC viewer promoted on November 12 – No Change.
  • Release channel cohorts:.
    • Custom Key Mappings project viewer, version 6.4.12.552100, November 12.
  • Project viewers:
    • Project Jelly project viewer (Jellydoll updates), version 6.4.12.552224, December 4.
    • Simple Cache project viewer, version 6.4.11.551403, issued on November 12.
    • Legacy Profiles viewer, version 6.4.11.550519, October 26.
    • Copy / Paste viewer, version 6.3.5.533365, December 9, 2019.
    • Project Muscadine (Animesh follow-on) project viewer, version 6.4.0.532999, November 22, 2019.
    • 360 Snapshot project viewer, version 6.2.4.529111, July 16, 2019.

In Brief

  • Map tiles are still not being regularity updated, however the Lab both identified the cause of the issue and a possible fix, however, it now seems probable this will not be deployed until after the holiday break.
  • The updates to Group chat made over the last day or so should not be seen as a “complete fix” for issues. Rather, it is intended to hopefully improve things for at least some who have experienced problems,with further work to come, with Oz Linden noting:
There is no doubt that group chat needs additional work. We have recently resolved some problems that we were able to diagnose, but more work will be needed as soon as we can devote some time to it.
  • It  is possible that post-Uplift, EEP might see some further work, including an adjustment to the default Mainland ambient lighting.

 

Grauland in December in Second Life

Grauland, December 2020 – click any image for full size

To take a break from scenes of snow and winter, we decided to head over to Grauland and see what region holder JimGarand had put together for December – and as always, we weren’t disappointed with what we found.

Over the years, Jim has never ceased to attract us – and many other visitors – with a series of unique region designs that never fail to offer something new and different, whilst also offering touches that persist between designs to present a sense of continuation from one design to the next.

Grauland, December 2020

With this iteration of the region, that continuance can be found through the maze of rooms and half-rooms last seen in the region’s summer looks, and the ranks of concrete blocks that have appeared in a number of the region’s designs.

The maze of rooms is the first element of the design to be encountered from the landing point, which sits on a pier head that thrusts out into the waters on the west side of the region, a crossed archway forming the walk from the pier head and the maze.

Grauland, December 2020

Beyond the rooms a series of broken walls form a zig-zag walk for those who fancy it – or visitors can go around this to the north, where they’ll encounter a pattern of “portal blocks” – hollow concrete blocks with circular holes in their six sides, inviting people to walk through them, or head southwards where, a little further inland, stands the rows of concrete blocks, standing close to where steps have been cut into the bare rock of an upland table of rock.

These steps lead up to a most unusual tower that rises from a rough table of rock. apparently made of concrete it raises a single square finger into the air which splits at its top into four arms, each forming an individual room leading off of the central stairwell. As a home, it offers a most unique residence – allowing for its outwardly industrial  look. However, here the structure is used as something of an artistic statement – art also being a common theme running through Grauland designs. Each room presents an individual décor from rings of multiple televisions through if not Santa’s grotto, then certain his hi-rise retreat, to a balloon-lovers paradise and a lounge where talking about the elephant in the room is unavoidable.

Grauland, December 2020

The tower is not the only structure on the island. Diagonally opposite it to the north-east and also sitting atop a large plateau, is another concrete building. Octagonal in shape, it appears to have a steeply-sloping, sectionalised roof. It is only on reaching it and taking the tunnel and stairs up into it, can it be seen that the building is actually open to the sky above – although what purpose it might be put to – gallery, event centre or even landing pad for some form of space vehicle – is entirely up to the imagination.

Directly south of of this, and also facing the tower is a large studio house with sunken gardens and swimming pool. The  courtyard around the pool offers both places to sit and sculptures to be appreciated. A small club house is to one side of the courtyard,  a hot tub alongside it, while a A single passage runs directly east to the water’s edge, flanked by further sci-fi elements in the form of strange pods  that offer little studio rooms where visitors can relax.

Grauland, December 2020

Finished in concrete and stone blocks. and with its outside metal stairways, the studio house continues the industrial theme of the setting, but offers comfortable furnishings within, its southern aspect overlooking a small wild flower garden sitting of a shelf of rock between house and sea.

With boats at the landing point, a little an aged and damaged garden shed sitting to the north-west offering a further unusual hideaway, and seating offered throughout, Grauland invites explorers to wander inland and around its rough coastline (rocky outcrops and cliffs allowing, while its low-laying inland mix of blocks, walls (straight and sinuous) offers an artistic statement in its own right.

Grauland, December 2020

Thus, this iteration of Grauland continues the region’s reputation for being an engaging, curious and photogenic visit for all who appreciate exploring Second Life.

Space Sunday: the flight of SN8 and a round-up

On Wednesday, December 9th, SpaceX Starship prototype SN8 finally took to the skies in what was to be a very mixed ascent to around 12.5 km altitude and return to Earth.

The much anticipated flight of the prototype vehicle, weighing approximately 672 tonnes with its partial fuel load, was far more successful than SpaceX had anticipated, even if the vehicle was lost in what SpaceX euphemistically calls a “rapid unplanned disassembly” or RUD.

The first attempt at a launch of the 50m tall vehicle was made on Tuesday, December 8th; but this was scrubbed after a pre-flight engine issue caused an automatic shut-down on all three Raptor motors. The second launch attempt, in the morning of Wednesday, December 9th, was aborted just 2 minutes and 6 seconds before engine ignition when a light aircraft strayed into the no-fly zone around the SpaceX facilities in Boca Chica, Texas.

The moment of ignition caught by ground cameras (l) and camera on the hull of the vehicle (top r), and in the engine bay (bottom r). Credit: SpaceX

However, at 16:00 CST (22:00 GMT) that day, the countdown resumed, and at 16:45:26 p.m. CST (22:45:56 GMT), the three Raptor engines on the vehicle ignited and ran up to around 80% thrust, lifting prototype SN8 into the air.

The entire flight was live streamed by SpaceX, with the initial ascent proceeding as anticipated. At 1 minute and 40 seconds into the flight, one of the Raptor engines shut down and gimballed itself away from the remaining two operating motors. 94 second later, a second of the Raptors did the same. At the time, some pundits commenting on the flight speculated the shut-down indicated something was amiss.

The first of the Raptor engines shuts down – a planned part of the flight – as SN8 burns through its partial fuel load, so as to reduce its thrust-to-weight ratio. SpaceX

In actual fact, both engine shut-downs were planned. As the vehicle was flying with around 1/2 its normal fuel load, and getting lighter at the rate of 2.2 tonnes every second, the engines were shut down to reduce SN8’s thrust-to-weight ratio, naturally reducing its rate of ascent.

Even so, SN8 continued upwards under the thrust of the one remaining Raptor – Number 42, the latest and most modern Raptor engine evolution, with the vehicle’s reaction control system (RCS) firing thrusters around its hull in order to stay upright, until it reached a point where it was effectively hovering.

The moment of tip-over: SN8’s Raptor 42, assisted by the vehicle’s RCS thrusters, starts to tip the vehicle over into an horizontal orientation. Credit: SpaceX

What happened next was one of the two most incredible sights witnessed in the testing of a space vehicle: as SN8 started to drop vertically backwards, Raptor 42 gimballed to direct its thrust at an angle, working with the RCS system to tip the entire vehicle over until it was falling more-or-less horizontally. At this point, the fore and aft flaps came into their own, working in tandem to hold the vehicle steady, much like a skydiver uses their arms and legs to maintain stability.

This skydive / bellyflop (as some unkindly refer to it) is how a Starship will make a return from orbit. Dropping into the atmosphere with the fore and aft flaps folded back against the hull to minimise their exposure to the fictional heat of atmospheric  entry, an operational starship will be protected by heat shield tiles along its underside, after which the flaps fold out, acting as air brakes to slow the vehicle’s velocity as well as keeping it stable.

Dropping back through the atmosphere for almost two minutes, SN8 then completed the second most incredible sight seen in the testing of a spacecraft when, six minutes after launch, two of the Raptor motors re-ignited, using fuel from two small “header” tanks. These, coupled with the vehicle’s RCS tipped SN8 back to an upright position just 200 metres above ground.

The idea had been for the vehicle to then descend tail-first over the landing pad, deploy its landing feet and touch-down. However, it was at this point things went wrong. With just tens of metres to go, one of the two operating engines shut down. For several seconds, the remaining engine fought to maintain vehicle stability, its exhaust plume turning bright green. Seconds later, its landing legs having failed to deploy, SN8 slammed into the landing pad and exploded in the RUD SpaceX thought might occur at some point in the flight.

The unusual green exhaust plume of the single remaining Raptor motor is clearly visible as SN8 almost overshoots the landing pad, and the failed deployment of the landing legs is visible in the image of vehicle. Three second later, the vehicle hit the landing pad and exploded. Credit: SpaceX

Initial analysis of data from the flight suggests that the header tanks suffered a pressurisation issue that prevented them pushing sufficient fuel into the two Raptor engines, causing one to shut down completely. The green plume from the second motor is thought to be one of two things: either that a) as the motor was so starved of fuel, it started consuming itself, material inside its turbopumps turning the exhaust green; or that b) as one engine shut-down unexpectedly, the second started gimballing wildly to try an maintain the vehicle’s orientation, and in doing so, smashed its engine bell into the other motor, exposing its copper cooling circuits, which caught fire and turned the exhaust plume green.

Snow white days at Jacob in Second Life

Jacob, December 2020 – click any image for full size

At the start of December, Shawn Shakespeare reminded me that it’s been a good few years since I’ve written about the End of Time estate, and suggested taking another look at Jacob, one of the regions within the estate, and which has traditionally stood a little aside from the rest of the regions there in terms of looks and presentation.

Currently, the region sits as a winter setting,  designed by Holly Texan (Dacotah Longfall) that is both simple and effective – particularly if you enjoy long, bracing walks through a snowy landscape, hearing the crunch of fresh snow beneath your feet and feeling the crispness of cold air in your sinuses. It’s a setting that is ideal for photographers and rich in subtle details.

Jacob, December 2020

The landing point is tucked into the north-west corner of the region, within sight of the some of the other regions in the estate, the water channel between them and Jacob apparently frozen. A welcome sign informs arrivals that clothing is optional – although skipping through the snow sans boots and clothes is not my idea of a fun afternoon, so was decidedly with clothes during my visit 🙂 .

The snow leading away from the sign is rutted with tyre tracks that run between fencing that marks out individual fields on either side, before the southern side of the road opens out to an ice-covered lake. Passing over a covered bridge, the tracks point straight and true to a farmhouse on the east side of the region. A second set of tracks points northwards, perpendicular to those running across the front of the farmhouse, and lead the way to a large barn where best wishes for the US Thanksgiving holiday and the Christmas holiday season are offered to all who visit the region.

Jacob, December 2020

A flat landscape, the region is home to the fields mentioned above, where horses and deer wander and attempt to graze on the grass sitting under the carpet of snow. Copses of trees are scattered across the land, whilst to the south-west, an old steam locomotive is huffing its way along tracks that curve across that corner of the region.

The touches of detail can be found in the way that the deer and horses have left their own footprints in the snow – so often in winter regions, animals appear to be able to move across a landscape heavy with snow without ever seeming to break the virgin surface (although admittedly, there are elk that also appear able to do so!). Similarly, the grounds of the house show signs of human handiwork not just in the presence of snowmen, but in the footprints criss-crossing the snow, suggesting the industrious hands that have made them.

Jacob, December 2020

As a Calvin and Hobbs fan (and who among us, having read Bill Watterson’s  tales of a young boy and his stuffed tiger isn’t?), I couldn’t find the snowmen in the grounds of the farmhouse mindful of Calvin’s antics: one apparently up to his neck in “quicksand” (although he doesn’t seem unhappy about that), and the other having lost his head, which lies with a broken nose on the snowy ground. Whether or not both are intended to evoke Calvin’s approach to snowman making, I’ve no idea, but I like to think of them in that way, adding as it does a sense of fun to the setting.

For those who need them, rezzing rights can be obtained by joining the End of Time group – but if you do rez props, etc., for photography or anything else, please remember to pick things up behind you.

Jacob, December 2020

Easy on the eye and on the viewer, Jacob remains a light, engaging visit.
