SL project updates 16 4/1: server updates

Gates of Memories; Inara Pey, January 2016, on Flickr Gates of Memories – blog post

Server Deployments

As always, check the server deployment thread for the latest updates.

On Tuesday, January 26th, the Main (SLS) channel received the server maintenance package, 16.01.16.310114, previously deployed to the three RC channels. This comprises:

  • A simulator crash fix
  • A further feature request: llGetObjectDetails() functionality to get the parent_id of any task in the region (OBJECT_REZZER_KEY).

OBJECT_REZZER_KEY returns the parent_id of any task in the region. If the object came from an object rezzer it returns the ID of the parent object, while If it was rezzed by an avatar, it returns the agent ID of the avatar. The function only works for those objects rezzed in-world after the code deployment (objects in-world prior to deployment will return NULL_KEY).

On Wednesday, January 27th, the three RC channels should all receive a new server maintenance package,16.01.21.310177, comprising:

  • Internal simulator fixes
  • A fix for BUG-1313 “LSL llSetPos in root prim of attachment behaves differently at high altitudes – viewer does not show updates”, which can cause attachments to fail to update correctly at altitudes over approximately 1500 metres.

Deployment Slowdown

“FWIW, we’re likely to slow down on server updates in the next couple of weeks,” Simon Linden informed those attending the Simulator User Group meeting on Tuesday, January 26th. “It’s not part of any evil plan, but I’m doing some internal maintenance work and travelling one week.”

How this plays out remains to be seen, but we should at least have one deployment to the Main (SLS) channel in week #5 (week commencing Monday, February 1st), assuming no issues are found, with the promotion of the this week’s RC deployment to that channel.

SL Viewer

no updates for the start of the week, with the current crop of viewers remaining:

  • Current Release version: 4.0.1.310054, January 15 – formerly the Maintenance RC viewer download page, release notes
  • Release channel cohorts (please see my notes on manually installing RC viewer versions if you wish to install any release candidate(s) yourself):

  • Obsolete platform viewer (Windows XP and OSX versions below 10.7), version 3.7.28.300847 dated May 8th, 2015.

Other Items

Greater Local Region Control

A bug which has been getting repeated requests for attention, particularly by those engaged in SL combat activities, is BUG-8974, “Temp rez object are not rezzed in a timely manner”. It’s also one which hasn’t seem to be working its way to the top of the pile of things to be done. During the Simulator User Group Meeting, Simon expanded on one of these reasons this is the case:

“As I remember, it’s tied up with a larger idea: letting region owners pick different settings for the region based on the performance and safety you want.  Part of the problem is due to a throttle which was added for anti-griefing. So if you want temp rezzing faster, you might want that [throttle] looser, while a venue owner would definitely not want that [the throttle looser, due to the risk of griefing]. I can’t make promises but I hope to get to it soon.  It’s still on my list.”

Cica’s Beginners in Second Life

Beginners - Cica Ghost
Beginners – Cica Ghost

“I made these travelling houses, like migrating people,” Cica Ghost told me of her latest installation, Beginners. “And I was thinking, they are looking for new beginning. I didn’t want political thoughts, especially not in SL. So I think they are just moving., travelling. “Migrants” is such a heavy word.”

And it is, particularly in the current political climate and the situations occurring in Africa and the Middle East. Yet, with Beginners, it is in some ways hard not to see a reflection of what is happening in the physical world.

Across a rocky landscape, devoid of trees but covered in part by breeze-swayed grass, a caravan is slowly making its way up an incline. Pulled by gigantic snails, each with a house on its back, the caravan comprises two sets of wheeled houses, yoked one to another, the leading ones in each train harnessed to one of the aforementioned snails.

Progress is slow. the snails stretch and contract, the wheels on the house turn, but forward momentum seems non-existent. And all of this is watched by enormous figures standing on nearby hills or seated on the edge of the grasslands. Somewhat unkempt, their faces twisted, the sleeves of the jumpers they wear stretched and hanging over hands, Cica refers to them as trolls, and notes they mean no harm; they’re just there to watch.

Taken as individual scenes, the snail caravan and the huge figures offer a humorous study; the poor snails stretch and try, stretch and try, without ever showing signs of reaching a particular destination, hauling gaily painted houses (which show signs of wear), while the troll figures offer a clown-like face and look to the world; their oversized jumpers giving them a gentle charm.

Nevertheless, the echoes of migration and the displaced cannot be entirely put aside. It’s there within the caravan, where a closer examination of the houses reveals that their careworn look might actually be the result of being caught in strife. It’s there in the idea of people moving their entire home to seek a new beginning and leave the past behind. It can even be found with  the trolls, although this might not initially be obvious.

As tall as they might be – easily matching the wheeled houses in height – the trolls and their relationship with the caravan take on a new meaning as you cam closely around them. As the caravan on the rigid comes into sight, the trolls aren’t giants any more. They are instead transformed into figures in the foreground, watching the distant caravan roll by, their expressions now filled with pathos and bewilderment, perhaps a reflection of inner turmoil at being unable to go on the journey as well.

There are other subtle nuances as well. For example, the landscape is pockmarked with craters, giving it an alien look in places. And “alien” is often a term we use is respect of those arriving in our lands from elsewhere, or when referring to lands and customs removed from those we have lived with.

Beginners is again another marvellous piece by Cica, working as it does on several levels. Whether or not one is struck by the potential parallels with the dispossessed, this is an installation which is hauntingly beautiful in its presentation. There is also Cica’s trademark sense of fun: you can sit on the roofs of the houses if you wish as the snails struggle forward, or you can ride a balloon over the fields (and beneath the waters!), either on your own or with a friend. And if you do look hard enough, you’ll find a little secret spot where you can curl up and relax, leaving the world above you to get on with itself.

Space update: seeking planet X, examining comets and sifting sand

CuriosityNASA’s Curiosity rover has been sampling the sands of the “Namib Dune” the vehicle has been studying / circumnavigating for the last few weeks as it studies an extensive dune field which is slowly making its way down the slopes of “Mount Sharp” on Mars at the rate of about a metre per year.

“Mount Sharp”, more formally called Aeolis Mons, is the huge mound of material gathered against the central impact peak of Gale Crater. It forms the rover’s primary mission target in its quest to better understand conditions on Mars down through the ages, and to look for areas which at some point in the planet’s past, may have had all the right conditions – minerals, chemicals, water, heat, shelter, etc., – which might have allows life to arise.

The dune field on the north-east flank of “Mount Sharp” is of considerable interest to scientist, as it is the first genuine dune field to be studied on another world, and obtaining a clearer understanding of how the Martian wind moves sand could lead to a clearer picture of how big a role the wind plays in depositing concentrations of minerals often associated with water across the planet, and by extension, the behaviour and disposition of liquid water across Mars.

On January 12th, the rover reached a target area for sample gathering dubbed “Gobabeb”, and even this presented a challenge. Curiosity had to manoeuvre up onto the dune, and then turn in place in order to start sample gathering operations. This meant a cautious approach to the location, initially “scuffing” the sand to obtain and indication of its depth and composition (loose firm material). After this the rover gently edged onto the sand and deployed the robot arm to use its small scoop in only its second major sample gathering exercise, which took place on January 14th.

The sand gathered by the operations well be sorted within the CHIMRA system inside the robot arm, which uses a series of sieves to divide the sand grains by coarseness. Once sorted, the samples are delivered to the rover on-board chemical and analysis systems  – ChemMin, the Chemical and Mineralogical laboratory and SAM, the Sample Analysis at Mars suite – for examination.

A second sample of sand was gathered on January 19th, and is currently awaiting processing.

CHIMRA
CHIMRA – the Collection and Handling for In-Situ Martian Rock Analysis device attached to the turret at the end of Curiosity’s robotic arm, processes samples acquired from the built-in scoop (red) and the drill, which is not shown but is also part of the turret. CHIMRA also delivers samples to the analytical lab instruments inside the rover. Two paths to get material into CHIMRA are shown (the scoop delivers material to the location marked at the bottom, and the drill deposits material to the sample transfer tube shown at top). Also marked are the location of the vibration mechanism used to shake the turret and cause the sample to move inside CHIMRA, and the portion box (yellow) from which the material processed through a sieve is delivered to the analytical lab instruments.

Europe Joins Dream Chaser

In my last Space Sunday report, I covered the news that Sierra Nevada Corporation (SNC) will be joining SpaceX and Orbital ATK in supporting US work to delivery supplies to, and remove waste from, the International Space Station.

As a part of a new contract which commences in 2019 and runs until 2024, the expected end of ISS operations, SNC will utilise an unmanned cargo version of its Dream Chaser “mini shuttle”, which is based on a lifting body design, to carry up to 5 tonnes of material to the space station. Now Europe has officially joined SNC as a strategic partner.

SNC and Europe have been looking at options for Dream Chaser development since SNC lost out to SpaceX and Boeing to supply the crewed version of Dream Chaser to NASA for ferrying crews back and forth between the ISS and US soil. Confirmation that NASA will be using Dream Chaser for the resupply flights means that ESA can nor push ahead with developing an International Berthing and Docking Mechanism (IBDM) for Dream Chaser.

Lab Chat #2: Ebbe Altberg – transcript and audio

Lab Chat #2, January 21st, 2016 - Jo Yardley, Ebbe Altberg and Saffia Widdershins
Lab Chat #2, January 21st, 2016 – Jo Yardley, Ebbe Altberg and Saffia Widdershins

Update Wednesday, January 27th: The official Lab Chat #2 video is now on-line, and is embedded at the end of this article.

Thursday, January 21st saw the  second in a series of discussions called Lab Chat, billed as “an opportunity for you to ask Lindens your questions during a live taping that will be recorded and archived for everyone to view.”

As with the first show, the session featured the Lab’s CEO, Ebbe Altberg in his alter ego of Ebbe Linden. In preparation for the recording, Second Life users were invited to ask questions about the Lab, Second Life, “Project Sansar”, etc on a forum thread.

Over 80 questions were asked, all of which were reviewed by the Lab Chat production team, and from which the list of question to put to Ebbe was drawn. The questions select were those the production team thought would be of most interest to the attending audience, or represented those questions which were asked multiple times by different people.

The following pages offer a transcript of the show’s recording session, which has been split into three parts:

  • Those questions and answers those related to Second Life
  • Those focused more on Project Sansar
  • Additional questions & audience Q&A.

The first two sections are presented in chronological order – as the questions were asked during the recording of the show. The additional questions have been grouped together (where possible) by subject matter, for ease of reference.

The Quick Links below will take you directly to each of these three sections, or to any of the individual discussion points within them. Each question / answer includes an audio extract of that question and response for those who wish to listen rather than read.

Note: this is not a transcript of the entire recording session. The focus is on the questions asked and responses given. Also, the audio extracts are from a recording which was cleaned-up following the show to remove repetitions, pauses, trailing comments which otherwise break the flow / context of replies. However, no attempt has been made to editorialise or in any way alter the context of any response given to questions.
