SL10BCC: of elephants, a turtle and thoughts of a knight

Posted on by Inara Pey

There’s no SL10BCC banner heading this post, as I’m writing as “me” rather than in any official or semi-official capacity.

With just 10 days to go, things are really shaping-up on the SL10BCC regions, and there are some really stunning builds coming together. For the last few days I’ve been peeking-in on the main stage sets, and have to say that if you found the stages from SL9B to be pretty special – then prepared to have your socks blown off )and possibly out the nearest window) this year.

The stages are amazing.

"We approach A'stra from seaward. I could scarce believ my eyes - the legends were true! An entire islands carved into the likeness of a giant turtle, beautiful waterfalls tumbling from its back which was itself a verdant green land. As the Captain dropped anchor, I took pen to paper, anxious to capture this wonderful land we were about to exlpore..."

An entire islands carved into the likeness of a giant turtle, beautiful waterfalls tumbling from its back which was itself a verdant green land. As the Captain dropped anchor, I took pen to paper, anxious to capture this wonderful land we were about to explore…”

I actually wanted to bring you images of the main stage yesterday, but Whiskey Monday got some incredible shots, one of which was taken from a similar angle as one of mine, so I wanted to avoid seeming like I was trying to steal her thunder.

To appreciate the main stage, you really have to see it; covering two regions, it is simply awesome and offers so much to see an explore in its own right. I’ve post-processed the images here not so much to show off that I can, but because I want you to have some element of the same wonder and awe I experienced in exploring the stage, and so didn’t want to give too much away with colour snaps :).

"We took to the long boats on the morning tide and made our way inshore. A path led towards a bridge and a route up onto the island, and the others were quick to set of in exploration. I waited a while, content to draw the great head of the 'beast'..."
“We took to the long boats on the morning tide and made our way inshore. A path led towards a bridge and a route up onto the island, and the others were quick to set of in exploration. I waited a while, content to draw the great head of the ‘beast’…”

The entire build resonates strongly for me. For a start, the name of the stage is A’stra, taken from the motto Ad Astra Per Aspera, through hardship to the stars, which is very close to the motto of the Royal Air Force in which my father served, Per Ardua Ad Astra (meaning roughly the same thing). Then there are the unmistakable primary motifs for the stage: a giant turtle with four elephants upon its back…

OK, so the discworld isn’t sitting upon the backs of the elephants, who are all busy with other tasks (two providing support for the main bridge leading to the stage, for example), but if you are in any way familiar with the works of Sir Terence David John “Terry” Pratchett, then it’s hard not to feel a smile crossing your lips on seeing A’stra.

"Later in the day, my oils and canvas were brought ashore and while camp was established, I took myself away to give colour to this wonderful sight...."
“Later in the day, my oils and canvas were brought ashore and while camp was established, I took myself away to give colour to this wonderful sight, so beautifully created by artisans of such great skill….”

Nor is it entirely inappropriate. This year does, after all, mark five years since Sir Terry visited Second Life in October 2008…

The echoes for me running still deeper, tho. The “back” part of the stage is fabulously landscaped with a wealth of detail – gardens, statues, pools of water with steps leading into them and fountains with cascades of ree-flowing water that – as I have elsewhere in SL – I was immediately put in mind of Sri Lanka, and specifically, the great palaces of Sigiriya. Not that the stage set in any way resembles Sigiriya – far from it in terms of physical appearance – but rather tha the combination of jungle paths, ancient ruins, pools and so on tended to cast my mind back to the times I spent visited the Lion Rock citadel.

Explore the stage regions careful – there is a lot to see above and – in places – below ground, and there is a story to tell in various sculptures which line one of the paths leading up to the stage.

The main stage is just one of the core elements of the forthcoming SL10BCC celebrations – the water and cake stages are both equally as amazing. Together with the builds and exhibits which are rising out of the ground right across the celebration regions, the promise to make the community-lead celebration of SL’s 10th anniversary truly magnificent.

One of the many sculptures to be found lining a path leading up to the main stage and which together tell a story of their own.

My apologies for the relative low resolution of the above images (1440×900-ish). Sadly, and as with the Fantasy Faire regions in April, the SL10BCC regions are already more than my Ge900GT can comfortably handle when taking snapshots with bells and whistles switched on in any of my preferred viewers.

Getting set for a long drive

Posted on by Inara Pey

CuriosityAfter six months in “Yellowknife Bay”, Curiosity is getting ready to move on. Investigations in the area are due to come to an end in the near future, and with the new autonomous driving software now installed in the rover, it is anticipated that the long drive to “Mount Sharp” will begin very soon. The start of this phase of the mission will be marked by the Rover retracing its steps (tracks?) through “Glenelg”, the region so-named partially because it is a palindrome, reflecting the fact the rover would be driving through it twice.

How long the rover will take to get to “Mount Sharp” is entirely open to question, however. While Curiosity is now far more capable of autonomous navigation, it won’t be a case of “pick and route which looks good and go”. If nothing else, there is no way of knowing what the rover might discover while en route.

“We don’t know when we’ll get to Mount Sharp,” Mars Science Laboratory Project Manager Jim Erickson said at the Jet Propulsion Laboratory in Pasadena, California. “This truly is a mission of exploration, so just because our end goal is Mount Sharp doesn’t mean we’re not going to investigate interesting features along the way.”

The slopes of "Mount Sharp"
The slopes of “Mount Sharp” showing a “region of interest”  captured by Curiosity’s Mastcam in August 2012 while the rover was still at the “Bradbury Landing” site. Scientists are keen to explore the mesa-like outcrops on the side of the mound, although how long it will take the rover to get to them in subject to finding a suitable route and also upon what other discoveries lay along the rover’s path. The black dot in the inset image (actually a large rock) demonstrates how the rover might look from “Bradbury Landing” were it exploring “Mount Sharp” at the time the images was captured

In May, Curiosity completed a second drilling operation to obtain samples from inside an area of bedrock called “Cumberland” within “Yellowknife Bay”, delivering them to the Chemistry and Minerology (CheMin) and Sample Analysis at Mars SAM) suites of instruments aboard the rover for detailed analysis. This work is still ongoing, and it is hoped that the result will further confirm findings obtained as a result of the first drilling operation, carried out a few metres away on a rock formation dubbed “John Klein”, and which suggested that the area once had environmental conditions favourable for microbial life.

No further drilling operations are now planned for the area, although NASA has yet to give word on the results from the initial analysis of the “Cumberland” cuttings.  Additionally, once the order is given to start the drive towards “Mount Sharp”, the rover will retain cuttings from the “Cumberland” drilling ins its sample scoop which can be delivered to CheMin and SAM for additional analysis, if required.

Both drilling operations have been important steps for the MSL mission. Not only have they been a successful test / use of the last remain major science capability on the rover (the ability to drill into rocks and obtain samples), they’ve also been an important learning situation for mission engineers. Steps which each took a day each to complete when drilling at “John Klein” could be strung together into a single sequence of commands at “Cumberland”, allowing the rover to complete a number of drilling-related tasks autonomously and in a single day.

“We used the experience and lessons from our first drilling campaign, as well as new cached sample capabilities, to do the second drill campaign far more efficiently,” said sampling activity lead Joe Melko of JPL. “In addition, we increased use of the rover’s autonomous self-protection. This allowed more activities to be strung together before the ground team had to check in on the rover.”

It’s hoped that these capabilities will allow the mission team to plan future routines for the rover more efficiently and in the knowledge that Curiosity has the ability to carry out multiple tasks without the need to “‘phone home” at each stage of an operation, something which introduces considerable delays in activities as a result of the two-way communications lag.

Prior to leaving “Yellowknife Bay”, two further “targets of opportunity” will be subject to brief observations by Curiosity. The first of these is a layered outcrop dubbed “Shaler”, which was briefly looked at as the rover initially entered the “Glenelg” / “Yellowknife Bay” region, and a pitted outcrop called “Point Lake”

The science team has chosen three targets for brief observations before Curiosity leaves the Glenelg area: the boundary between bedrock areas of mudstone and sandstone, a layered outcrop called “Shaler”, a possible river deposit, and a pitted outcrop called “Point Lake”, a depressional area thought to be either volcanic or sedimentary in nature, and which the rover observed when entering “Yellowknife Bay” from “Glenelg”.

SL projects update week 23 (2): server, viewer, SSB/A, new LSL functions

Posted on by Inara Pey

Server Deployments, Week 23

As usual, the latest updates, feedback and comments can be found on the deployment discussion thread. Anyone encountering a specific bug is asked to file a JIRA.

  • There was no SLS Main channel roll out this week
  • On Wednesday June 5th, the Release Candidate channel received the following packages:
    • BlueSteel and LeTigre were updated with a new server maintenance project.  This project addresses a disconnection issue and also fixes a crash mode – see my notes from week 22, and a fix for a crash mode
    • Magnum remained on the same interest list improvement project as originally deployed to LeTigre in week 21, and to Magnum and BlueSteel in week 22, with some updates. Two of these fix what Andrew Linden describes as “two rare crash modes”. The package should also include the same disconnection issue fix.

Interestingly, the “large” scripts issue I reported on in part 1 of this update was given as the reason why there was not Main channel deployment this week. As previously reported, the fix for this issue, which prevents the text of previously saved scripts from being displayed in the script editor for users on slow connections, failed to make the cut for the week 23 deployments.

There are continuing reports of “invisible avatars” on Magnum regions. This issues was first reported following the week 22 deployments, and described as “on an in-region teleport when landing all surrounding avatars de-rezz and cannot be seen until the person re-logs. Everything else appears normally.” The problem appears to be random in nature, and was also noticed at one club which enjoys a high level of attendance. and which still appears to be encountering the same issue. During the Beta Server meeting on Thursday June 6th, this issue was discussed, and appeared to be most strongly linked to v1-based viewers.

SL Viewer News

The next release of the materials beta viewer arrived on Wednesday June 5th (3.6.0.276961 with the release notes here), and as I indicated in part one of this report, sees the beta once more installed into the “correct” folder (SecondLifeBetaViewer). This means the initial beta release needs to be uninstalled separately, as the updated version obviously won’t over-write it.

The materials project beta viewer had its first update on June 5th, with the release of 3.6.0.274961

In terms of beta releases in the future, it’s worthwhile again pointing-out that once the new viewer release process comes into effect, beta viewers will be installed into folders identified by their project name (e.g. something akin to “SecondLifeBetaMaterials”). Viewers should be fairly well self-contained (although they may still share the same default settings location, as that remains to be seen once things start rolling), so the uninstalling of individual beta versions (or RC versions) shouldn’t be a problem once they reach release status.

Work continues in preparing the new viewer release process for … release (or implementation). It’s still unclear whether it will arrive before or after materials moves to the release viewer. As reported in week 22, the current pipeline of releases we should be seeing as the new release process rolls forward includes:

  • A collection of open-source contributions to the viewer which is hoped will appear as a release candidate viewer pretty quickly
  • A “pretty substantial batch” of maintenance fixes for the viewer
  • Vivox updates, which Oz described as, “Finally getting attention again, and will probably be in a release candidate version ‘real soon’ now”
  • An Experience Tools viewer which is also expected to appear “real soon”
  • An interest list update viewer, which is believed to be getting closer to being stable

Server-side Baking / Appearance

Investigations have been continuing into the SUN-74 issue which affects non-SSB/A updated viewers (notably Phoenix), with Nyx Linden commenting at the Server Beta meeting that, “Thanks to the support from the phoenix/firestorm team, we’ve been able to identify the cause of that issue. We’re looking into what options are available to us. [It]  took some backflips to get it in a debugging environment, but managed to hunt it down – a combination of factors from not having the last 4 years of appearance fixes :)”
