The Drax Files Radio Hour 15: of Ebbe and education

radio-hourThe fifteenth installment of The Drax Files Radio Hour takes a look at Ebbe Altberg’s comments and Q&A session at this years Virtual Worlds Best Practice in Education conference which took place in both Second Life and OS Grid between April 9th and 12th.

The VWBPE session, which lasted a little under 90 minutes, featured some initial comments from Ebbe, followed by a wide-ranging Q&A session which many found both positive and perhaps a little revelatory (particularly given concerns ahead of his arrival at LL about him coming from “outside” LL / virtual worlds). Mal Burns videoed the session on behalf of VWBPE, and I have a full transcript for those who prefer to read rather than listen.

For those wishing to cut to the chase and jump to the clips from Ebbe’s presentation in the podcast and the discussion which follows, it starts around a quarter of the way into the show (14:19).

Some 15 minutes of Ebbe’s opening comments and the Q&A session are presented. These include his remarks on revisiting the Linden Lab Terms of Service (“we’re working on some simple tweaks to the language to make that more explicit”); his views on LL / SL and its position in the metaverse as a whole (“I think for starters, I’m mostly focused to get the ‘verse’ part right, and then we can think about ‘meta’ later on”); Facebook’s acquisition of Oculus Rift and more.

The excerpts are followed by a joint interview with Liz Falconer, Professor of Technology Enhanced Learning at the University of the West of England (UWE), and Stylianos Mystakidis, E-learning Manager for the Library and Information Centre at the University of Patras, Greece.

Intended to be a discussion of Ebbe’s VWBPE session, this actually covers much broader ground, from why issues such at the Lab’s bikini banner ads, can reinforce negative views of Second Life within the education sector, even though real life can be a lot more risky (and risqué) for students, through to the advantages of experiential learning and the potential of virtual worlds where such narrative styles of teaching are concerned.

At close to 24 minutes in length, the interview has to be listened to in order to be fully appreciated; Stylianos and Liz offer a considerable amount of food for thought – so much, in fact, that it is hard distill everything down into an article like this without either failing to do the various elements of the discussion justice or presenting you with a wall of text to read. This being the case, I’m going to focus on those aspects of the discussion which particularly struck one or more chords in me, while urging you to listen to the interview in full, if you haven’t already done so,

The first thing that particularly caught my attention came when Stylianos asked what is the one question that seems to be most easily avoided or ignored when people talk about virtual worlds achieving mass adoption – and that’s the question of why should people turn to  VWs rather than continuing to use all of the familiar tools and options they have at their disposal and which offer convenience and ease-of-use: Minecraft, Facebook, Skype and so on?

While it is true that access to a complex virtual world like SL does need to be addressed and simplified in order to make it easier for people to access such environments, and it is equally true that things like VR headsets will offer additional means of appreciating and enjoying VWs for those using them, I am far from convinced that technology and technical solutions alone hold the key to VWs achieving mass adoption. This is something I touched upon in reference to Philip Rosedale’s  keynote at the VWBPE; as Botgirl Questi eloquently and succinctly put it following that particular keynote:

Mainstream use of virtual worlds requires compelling mainstream use cases that clearly trump other options. Better technology doesn’t matter to people who don’t know why they’d want to use a virtual world at all. That’s the challenge that no one has successfully addressed.

SL projects updates week 16/2: server update, misc items

Server Deployments – recap

There were no deployments to the Main (SLS) channel or the BlueSteel and LeTigre channels during week 16.

On Wednesday April 16th, the Magnum RC received a new server maintenance package, which included a fix for BUG-5533 (“llTeleportAgent() and llTeleportAgentGlobalCoords() can break any script in any attached object that contains a change event.”).

Commenting on the latter at the Server Beta User Group meeting on Thursday April 17th, Maestro Linden said:

Unfortunately, after the roll we discovered that there was a regression in the Magnum update,  which was BUG-5763 (“AGENT_MOUSELOOK flag is often incorrect when llGetAgentInfo() is called within control() event”), which apparently affects certain guns (which only allow some actions when they think you’re in Mouselook) and certain vehicles (which change control behaviour when they think you’re in Mouselook).

The good news is that Kelly [Linden] came up with a fix for it yesterday, which is out on Aditi now. I gave it a whirl, and it looks like this bug is fixed. But if you have content that was broken by that bug, I’d encourage you to test it out on Aditi, in case there are any additional problems.

Those wishing to test the fix can do so on the Aditi regions Ahern, GC Test 10, and Tehama.  GC Test 10 is probably the most convenient to test on, as it mostly allows anybody to build and run scripts.

Week 17 Deployments

While the final details of deployments for the week commencing Monday 21st April will not be determined until the start of that week, it currently looks as though there will again be no deployments to with the Main (SLS) channel or the BlueSteel and LeTigre RCs, while Magnum will gain the BUG-5763 fix.

Commenting on the lack of high-profile server updates of late, Maestro pointed to the fact that the Lab has been engaged in a series of “invisible updates” recently, notably infrastructure improvements.

Group Chat Update

There were no further tests on Simon Linden’s group chat work, and Maestro indicated that testing on Agni may commence in week 17. An idea initially discussed for testing these optimisations on the main grid had been to use a single large group (the Firestorm Support group, due to both its size and frequency of use). However, commenting on the work, Maestro Linden said, “since the group chat changes are in the backend service, this would mean that … around 1/16 of groups would be on the group chat stuff.”

Other Items

HTTP-in Failures

Some people are noticing an uptick in issues relating to in-world scripts acting as HTTP servers (notably with HTTP-in functions). There has been a known bug with these (non-public BUG-2564)  wherein all http-in URLs and all capability URLs for connected users are dropped simultaneously, all the connected users get logged out, and HTTP-in scripts cannot be contacted. However, some of the issues people are experiencing appear to be occurring since the most recent HTTP updates were made. Lucia Nightfire describes the problems as, “random URL loss and instability is common esp after the http changes.” she goes on to note that she has had to “change http protocol and add heartbeats to some apps since the HTTP changes.” She further goes on:

Sometimes after I crash then relog into a region, its like my caps are reset and re-evaled and  in-turn all my HTTP devices all of a sudden cannot request URLs until the caps are reset or it is [a] repeat URL request failure. Long story short, if your viewer crashes, don’t log into your home region if you have servers there, or you risk interruption.

Maestro’s thinking on the matter is that it may be linked to a server crash – particularly given Lucia confirms the problem does occur as a result of a region crash – as there is nothing specific to a viewer crash which should upset things like HTTP-in functions. Further testing has been suggested to see if a precise cause can be identified.

Small blue dot on a red planet

CuriosityOn Wednesday April 16th, NASA JPL released a remarkable image captured using the High Resolution Imaging Science Experiment (HiRISE) camera on the Mars Reconnaissance Orbiter (MRO).

The image reveals the the Mars Science Laboratory, Curiosity parked alongside the multi-layered rock formation dubbed “The Kimberley”, as it prepares to undertake a range of science studies in the area.

The image was captured by MRO on April 11th during an overflight of the rover’s position as it sits at the foot of a rocky butte mission scientists have dubbed “Mount Remarkable”, and which forms a part of a multi-layered rocky location which has been dubbed “the Kimberley” due to its resemblance to a similar confluence of rock types found in Western Australia.

A rover’s progress: Curiosity, the blue form just off-centre in this false-colour image, sits at the foot of “Mount Remarkable”, a butte located in the area mission scientists have dubbed “the Kimberley”. the rover’s tracks can be seen leading back toward the top left corner of the image, where it entered the region on March 12th, 2014.

“The Kimberley” is an area of four distinguishable rock types exposed close together in a decipherable geological relationship to each other.  As such, they should provide further clues about ancient environments that may have been favourable for life. It is of particular interest to Scientists because like “Yellowknife Bay”, where the rover spent several months analysing and drilling rocks, “the Kimberley” demonstrates features which suggest that some of the rocks have only been exposed for a short time, geologically speaking.

This matters because Mars doesn’t have a magnetosphere and thick atmosphere like Earth’s, which protect us from energetic particles from space that break down organic material. So, rocks that have been exposed or close to the surface for a very long time are less likely to contain complex organic material, which might either be the remnants of past life, or help inform scientists about past habitability, the potential to support life in an area – as was the case with “Yellowknife Bay”.

The ghosts of castles past

Ghost Castle

During my SL travels, I may have mentioned I have a love of castles. So when I learned that Fuschia Nightfire, in association with Italian Square Gallery & Tanalois Art, was opening a new installation which takes England’s once mighty Corfe Castle as its inspiration, I was immediately intrigued.

Corfe Castle was established by William the Conquer in the 11th Century to command a gap in the Purbeck hills of Dorset (where Fuschia also lives in RL), and it was one of the earliest castles in England to be built using stone when the majority were built with earth and timber.

During a long and distinguished history, it served as both a royal fortress and later as a private residence. However, loyal to the crown in the English Civil War, the castle was besieged by Parliamentarian forces and eventually betrayed from within in 1645. Following its capture, Parliament voted to have it demolished, leaving a striking set of ruins atop the hill where it once stood.

Ghost Castle, Fuschia’s new installation, which opened on Wednesday April 16th, presents an interactive means of exploring a Norman castle. From the landing point, the visitor – assuming not too many people are already exploring – is presented with the castle ruins much as Corfe is seen today.

However, as you draw close to the ruins, things start to happen, with the gate house and curtain walls materializing before you, presenting vistas of the castle as it may have appeared in its heyday. As you pass by them, climbing up towards the keep, they fade away again, new sections of the castle appearing as you pass over or through them.

But as you approach, parts of it are slowly restored as they materise before you

The nature of the installation does make navigation a little difficult, as elements of the castle are necessarily phantom. This being the case, I recommend walking up to the curtain walls and then flying up to and around Henry 1’s great keep. Make sure – as the introductory notes at the landing point advise – that you have draw distance up relatively high and have set RenderVolumeLod (debug settings in the viewer) to around 4.00; both will be necessary for camming out to get good views of the castle.

Work with other visitors, or go in a small group, and you can reveal more of the oritinal structure

This is a novel and interaction way at viewing historical pieces in Second Life, one which could offer significant opportunities for things like educational recreations. It’s also an installation worth getting a small group together to visit, or while spending time working in cooperation with other visitors is worthwhile, so that you can work together to render more of the various elements of the castle simultaneously and so get more of a feel for how it might once have looked.

If there are enough of you, the full reichness of the castle might eventually be revealed

Lab asks for feedback on new Transaction History page

secondlifeOn Wednesday April 9th, I reported (under “Transaction History Oopsie”) on an error with the Transaction History page on people’s SL dashboards which lead to some upset and confusion after the familiar page was replaced with one that failed to show totals, and which had the familiar .XLS and .XML download options replaced by a single .CSV option.

The change lead to understandably negative  forum comments and a JIRA report (BUG-5664).

As a result of the upset, the page was rapidly withdrawn, and as I reported on April 12th, the Lab blogged on the matter, indicating they would be seeking users’ input to the matter going forward.

In line with this, the Lab issued a further blog post on Wednesday April 16th, entitled Try Out the New Transaction History Page, which reads in full:

Last week, we made a new page available as a replacement for the old Transaction History page. Due to your feedback, we rolled back the changes to this page to allow us to gather more feedback, and we are now providing this new page for review, without removing the old Transaction History page.

We have not yet made any changes to the new page, because we would like time to collect your feedback and review it. We have created a wiki page giving background on why changes were made to this page, where the new page is, and how to provide feedback. We will be closing feedback on April 30, 2014, so please take a look before then.

The wiki page repeats the blog post information, and confirms the primary reason behind the change:

The new Transaction History page was created to allow more than 500 transactions to be displayed for Residents with very active businesses.

It also invites people to provide feedback via the original BUG-5664 JIRA report raised by Sera Lok, which is open to comment for feedback.

Please bear in mind when examining the “new” Transaction History page, that no changes have been made to it since it was first revealed on April 9th – it is given purely as an example so that people can better identify and report issues they may have with it when comparing it to the existing Transaction History page.

People have been asked to provide feedback by Wednesday April 30th.

Reading through the comments, some constructive points have been put forward, although the range of comments doindicate the complexity of implementing changes like this, with people falling almost equally either side of individual changes. For example, many feel that providing only a .CSV download isn’t a problem, but an equal number feel that .XLS (and .XML) should be retained, as .CSV can create problems when it comes to processing the data contained n the downloaded file. Were I to be asked, I’d suggest that retaining .XLS (/ .XML) alongside .CSV would offer the most flexible approach. Backwards compatibility and not breaking legacy content (including scripted processes) has long been a watchword for the Lab when making changes to the SL platform – and this attitude should be carried forward with supporting services as well, such as the Transaction History page, to accommodate all those who have processes reliant on receiving their transaction data in .XLS.

What is healthy is that the Commerce Team appear to be listening and making a genuine effort to understand issues and concerns. Coming so long after what seems to have been a deliberate policy of disengagement by the team from merchants in many areas, this is undoubtedly welcome.

One can only hope this willingness is further reflected in how the new page is refined and updated going forward.
