SL Linux viewer to help bridge the gap

As noted in my recent article on the promotion of the Lab’s Alex Ivy 64-bit viewer to release status, there is currently no official 64-bit support for Linux at this time.

It is hoped with will change: the Lab is establishing a viewer build environment to build a Debian version of the viewer with the various specialist libraries required by the various flavours of Linux. The hope being that this, with contributions from the open-source community, will provide a means for the Linux flavour of the viewer to continue, with viewer developers adding the specific libraries they may need as required.

It’s not clear how long it will take for all of this to mature, and for a Debian version of the viewer to appear. In the meantime, it means that as the Lab baseline their viewer build process on Alex Ivy, and existing project and release candidate viewers are updated to the Alex Ivy code, they will cease having Linux versions. This can already be seen with the 360 snapshot viewer, the project render viewer, and the Nalewka RC at the time of writing (versions 5.1.0.506743, 5.1.1.511873, and 5.1.1.511871 respectively), none of which have a Linux flavour of the viewer. As the remaining project and RC viewers currently in the pipeline are updated with the new code case, they will also be without a Linux version for the time being.

To help compensate for this, on Thursday, January 18th, 2018, the Lab release the Linux Spur release candidate viewer, version 5.0.9.329906.  Dated November 17th, 2017, this viewer is in fact the Martini RC viewer which was promoted to release status on  November 29th, 2017 – the latest viewer to be promoted to release status prior to Alex Ivy being promoted.

While it is not explicitly stated in the release notes, it is unlikely this version of the viewer will be updated with bug fixes, updates, etc., but will be offered until such time as a Linux viewer using the 64-bit libraries is made available.  As such, it may offer a means for SL viewer users on Linux wishing to continue using that viewer, rather than a TPV flavour of Linux.

Obviously, those TPVs providing their own Linux flavour of the viewer are free to continue to do so.

Second Life: official 64-bit viewer and plans

On Tuesday, January 16th, Linden Lab promoted the Alex Ivy 64-bit viewer (version 5.1.0.511732 at the time of writing). This is a significant release, not so much because of any specific new features (although it does include improvements to media handling), but because it marks a number of important changes to the viewer.

Following the release, which Oz Linden blogged about the viewer and the Lab’s plans around it, on Wednesday, January 17th, 2018, and I’ve highlighted a few points of note from that blog post below – but do please read it in full.

Most notably, this version of the official viewer is built using an updated set of libraries (some of which will be undergoing a further update in the future), and a revised build process. It is currently being made available for download for Mac OS X (64-bit) and Windows (32-bit and 64-bit) – there is no Linux version of this viewer at this time, as explained below.

For Windows users, the most significant update lies with a new viewer executable, the SL_Launcher, which – as Oz explains in his blog post:

Manages the viewer update process, and on Windows also ensures that you’ve got the best build for your system (in the future it may pick up some other responsibilities). For Windows systems, the best build is usually the one that matches your operating system. For example, if you’re running a 64-bit Windows, then you’ll get the 64-bit viewer. If not, then you’ll get the 32-bit viewer.  However, some older video cards are not supported by Windows 10, so the launcher may switch you to the 32-bit build which is compatible for those cards. You won’t have to do anything to make this work – it’s all automatic – if you get an update immediately the first time you run this new viewer, it’s probably switching you to the better build for your system.

Oz also notes that if you have a shortcut to the viewer set-up, you should update it to point to SL_Launcher rather than the viewer .EXE, to avoid issues with running / updating the viewer, and indicates there is a slight bug with both the SL_Launcher and Second Life Viewer processes both show as icons on the OS X Dock, and will be fixed in a future update so that only a single icon is shown.

One of the things the Lab has been tracking with the Alex Ivy viewer is overall performance / stability. It had long be noted that running the 32-bit version of the Windows viewer on 64-bit version of Windows with more than 4 Gb of memory could lead to fewer crashes related to running out of memory. However, with the 64-bit version of the viewer, the Lab have seen further benefits for Windows users, and so are encouraging those who can to switch to using a 64-bit version of their preferred viewer, if one is available (e.g. users still running a 32-bit version of a viewer on a 64-bit version of Windows, or those upgrading their hardware to a system running 64-bit Windows).

Linux will be supported – if there is sufficient input from the open-source / Linux communities

Linux is the notable exception to the Alex Ivy branch of the official viewer, as there is currently no support for the operating system.

Linden Lab halted Linux development work in 2015 for a number of reasons (see here for more), and sought the support of the Linux community (who represent around 1-1.5% for the SL user base) to help maintain the viewer on Linux. More recently, as I’ve reported in a number of my weekly SL project updates (see here for an example),  the Lab has set out new plans for Linux support going forward, With Oz explaining:

We’re reorganising the Linux build so that instead of a tarball, it produces a Debian package you can install with the standard tools, and rather than statically linking all the libraries it will just declare what it needs through the standard package requirements mechanism. We’ll post separately on the opensource-dev mailing list with information on where that project lives and how to contribute to it.

Again, a key aspect of this project will be continued support from the open-source / Linux community to help maintain the Linux viewer going forward, in providing bug fixes, etc., and the Lab providing essential QA and the core build environment, as noted above. This approach is seen as beneficial, as it will remove many of the idiosyncrasies / overheads involved in producing a Linux viewer, such as maintaining multiples libraries associated with the viewer, and instead provide a basic viewer package which can be used by TPVs / Linux users to meet their specific preferences.

Some TPVs have already released versions of their viewers based on the Alex Ivy code, and Firestom’s upcoming release should also, I believe, include a 64-bit version based on Alex Ivy.

And if you’re wondering about the viewer’s name – as Oz explains (and I noted back when the first 64-bit project viewer appeared), Alex Ivy is derived from 64 in Roman numerals: LXIV – aLeX IVy.

 

Looking at the Second Life 2017 year-end Grid Survey report

La virevolte; Inara Pey, December 2017, on FlickrLa virevolteblog post

On December 31st, 2017, Tyche Shepherd issued her year-end summary on the general size and state of the Second Life main grid.

In terms of a percentage loss, 2017 saw private region losses return to the 2014/2015 levels, with a 4% decrease through the year, somewhat lower than seen in 2016. In all, 677 private regions of all classes were removed from the grid in 2017, compared to 992 in 2016. At the same time, the number of Mainland  / Linden held regions increased very slightly from 6,744 to 6,806 (up by 62), leaving an overall net loss of 605 regions across the grid as a whole.

Taking the year-on-year figures from 2010 onwards (that being the last year the grid exhibited a growth in the number of regions), we get the following breakdown for private regions:

2010 2011 2012 2013
24,483 23,857 20,994 19,273

673 3.5% 825 4.4% 992 5.6% 677 4.0%

Working on the basis of Tyche’s Full Private Region surveys I have to hand, a breakdown of approximate recent monthly revenues from private regions over the most recent four-year period might be given as:

  • November 2013: US $3,857,000 (+/- US $52,000)
  • March 2016: US $3,385,000 ( +/- US $43,000)
  • December 2016: US $3,162,000 (+/- US $39,000)
  • December 2017: US$ 2,970,000 (+/- US $36,500)

This represents around a 23% drop in monthly tier revenues over a four-year period. Of course, there are other revenue routes associated with Second Life – notably Premium memberships (which the Lab has in the past indicated account for around 20% of revenues). More directly, the end of 2016 / start of 2017 saw the Lab generate an estimated US $80,000, which doubtless help offset the decline in tier revenues to some extent. So, taking these factors into consideration, I would suggest that overall, the Lab might still be generating around US $48-49 million in revenue, or roughly the same as my estimate from my 2016 end-of-year article.

In 2016 there was some speculation that any opening of Sansar might have an impact on SL’s landmass. In my 2016 piece, I expressed the opinion this would not be the case, noting:

Some have raised concerns over how much of an impact Sansar will have on SL’s landmass in 2017. I actually don’t think it will. While I anticipate the decline in land will continue (but hopefully at a slower rate than 2016), I simply don’t think Sansar will have any immediate impact on Second Life one way or the other. Not in its first year, at least.

Unsurprisingly, this has proven to be the case: region losses for the second half of 2017, following the opening of Sansar’s public Creator Beta, remained pretty much on a weekly par with the months prior to the Creator Beat opening. I expect this will continue to be the case through much – if not all – of 2018.

Private estate numbers downs and ups in 2017 – click for full size

For me, the question remains as to how the Lab might respond to the slow tier revenue decline. As unpalatable though it may be to some, the answer still isn’t any tier cut, for the same reasons I gave back in 2013.  Simply put, from the Lab’s perspective  – and contrary to popular misconceptions on the matter – what users might consider  a “reasonable” tier reduction could actually be more immediately damaging to LL’s bottom line revenue generation, and bring with it no actual guarantee it would be overcome through any sustained demand for private land.

A better way – again from the Lab’s perspective – to relieve any pressure causing by reductions in revenue would be to reduce the costs involved in running ad maintaining Second Life. Doing so may not yield direct benefits to users in terms of tier reductions – but given the Lab’s sensitivity to the subject, they could over time provide the means for the Lab to reduce the tier paid by users. In the meantime, reducing costs allows the Lab to better leverage revenue into bankable profits. This is true, as well, for the work to move Second Life to the cloud – although hopefully, as the Lab has indicated, this might also eventually result in new land products / more flexible pricing. We just perhaps shouldn’t anticipate this happening in the near future.

Might we see Horizons expanded or a re-run of the buy-down offer in 2018? Possibly; although if either were to be tried, I suspect were there to be a move towards one or the other, it would likely be more to s further run of the buy-down offer, rather than an expansion of Horizons. That said, I actually anticipate that 2018 will see a further drop in region numbers, albeit one hopefully / most likely slower as then year unfolds than that of 2017. I doubt there will be any significant reversal unless something happens to cause a sustained growth in the overall numbers of users actively engaged in Second Life.

Peter Gray to depart Linden Lab

Courtesy of Linden Lab

Peter Gray, Linden Lab’s Senior Director of Global Communications is departing the company after nine  years.

Peter broke the news to me via e-mail on Tuesday, January 2nd, 2018 prior to e-mailing a number of other people. He first joined Linden Lab in 2009 from Lewis PR, a technology-focused company, where he gained his first exposure to both Linden Lab and Second Life. This means his experience with the company extends back more than a decade.

It’s been a privilege to represent Linden Lab, our innovative products, and their incredible users as a Linden for the past nine years. I wish our user communities and my Linden colleagues all the best for the future, and I’ll be rooting for their continued success.

– Peter Gray, Senior Director of Communications, Linden Lab

Throughout his time at the Lab, Peter has been one of the public faces of the company, rising from PR Specialist to his current position of Senior Director of Global Communications, gathering a wealth of knowledge about the Lab’s products along the way. In-world, his Classic avatar has often been visible at events such as the SL Birthday celebrations, taking questions at Meet the Lindens events, VWBPE conferences and more. More recently, Peter’s role has extended beyond Second Life to encompass Blocksworld and Sansar, and he has never failed to deal with the myriad question I and a lot of other bloggers have forwarded to the Lab over the years, as and where he has been able to do so.

In departing Linden Lab, Peter is moving on to  a new role with the communications team at Facebook AI Research  – and I wish him well in the new role, although I can honestly say he will be sorely missed.

Peter Gray and his Linden alter-ego

On a personal level, I would like to take this opportunity to publicly thank Peter for all of his help over the years; I’ve deeply appreciated our working relationship, and can say with hand on heart that his support, assistance and insight is one of the major reasons I’ve kept on blogging about SL for so long; his support – and what of the Lab as a whole – has, I believe allowed me to present news and information through these pages objectively, and in the knowledge it is as accurate as I could possibly make it.

Throughout all our time in correspondence and conversation, Pete has never been anything less than open, supportive and friendly. I’d like to further thank him for the personal invite to pop into the Lab and pay him a visit if ever I managed to get back to California and make my way up to San Francisco; I’m genuinely sad I never got to take him up on the offer.

Many thanks again, Peter, and wishing you all the best for 2018 and the future!

Space Sunday: helicopters, telescopes and cars in space

Back in August I wrote about a proposal from the Johns Hopkins Applied Physics Laboratory (APL) to fly a robotic helicopter to Saturn’s moon Titan.

Called “Dragonfly”, the mission would use a nuclear-powered dual-quadcopter, an evolution of drone technology, carrying a suite of science instruments to study the moon. Capable of vertical take-off and landing (VTOL) operations, the vehicle would be able to carry out a wide range of research encompassing Titan’s atmosphere, surface, sub-surface and methane lakes to see what kind of chemistry is taking place within them.

The proposal was one of several put forward for consideration by NASA as a part of the agency’s New Horizons programme for planetary exploration in the 2020s. In late December 2017, NASA announced it was one of two finalist proposals which will now receive funding through until the 2018 for proof-of-concept work.

Titan has diverse, carbon-rich chemistry on a surface dominated by water ice, as well as an interior ocean. It is one of a number of “ocean worlds” in our solar system that hold the ingredients for life, and the rich organic material that covers the moon is undergoing chemical processes that might be similar to those on early Earth. Dragonfly would take advantage of Titan’s dense, flight-enabling atmosphere to visit multiple sites by landing on safe terrain, and then carefully navigate to more challenging landscapes.

At 450 kg, Dragonfly is no lightweight, and a fair amount of the mass would be taken up by its nuclear power unit. However, the vehicle will carry a science package comprising some, or all, of the following:

  • A mass spectrometer for analysing the composition of Titan’s atmosphere and surface material.
  • A gamma ray spectrometer of analysing the shallow sub-surface.
  • A seismometer for measuring deep subsurface activity.
  • A meteorology station for measuring atmospheric conditions such as wind, pressure and temperature.
  • An imaging system for characterising the geologic and physical nature of Titan’s surface and identifying landing sites.

Commenting on the NASA decision to provide further funding for the project, APL Director Ralph Semmel said:

This brings us one step closer to launching a bold and very exciting space exploration mission to Titan. We are grateful for the opportunity to further develop our New Frontiers proposals and excited about the impact these NASA missions will have for the world.

The second proposal to receive funding through until the end of 2018 is the Comet Astrobiology Exploration Sample Return (CAESAR) mission proposed by Cornell University, Ithaca, New York and NASA’s Goddard Space Flight Centre.

This mission seeks to return a sample from 67P/Churyumov-Gerasimenko, a comet that was successfully explored by the European Space Agency’s Rosetta spacecraft, to determine its origin and history. This project is being led by Steve Squyres of Cornell University, who was the principal investigator for NASA’s Mars Exploration Rover missions featuring Opportunity and Spirit.

If approved by NASA, CAESAR would launch in 2024/25, collect at least 100 g (3.5 oz) of regolith from the comet, separating the volatiles from the solid substances. The spacecraft would then head back to Earth and drop off the sample in a capsule, which would re-enter Earth’s atmosphere and parachute down to the surface in 2038. 67P/C-G was selected because it has been extensively imaged and mapped by the Rosetta mission, thus enabling engineers to design a vehicle better able to meet the conditions around the comet as it swings around the Sun.

New Frontiers is a series of planetary science missions with a cap of approximately US $850 million apiece. They include the Juno mission to Jupiter, the Osiris-REx asteroid sample-return missions, and the New Horizons mission to Pluto, also built and operated by APL. Under the terms of NASA funding, both of the 2017 finalists will receive US $4 million each in 2018, and a final decision on which will be funded through to completion will be made in 2019.

WFIRST: Hubble’s New Cousin

While attention is on the next space telescope due for launch – the ambitious James Webb Space Telescope (JWST), which will be departing Earth in 2019 – NASA and the international community is already turning its attention to the telescope that will come after JWST, with a launch due in the mid-2020s.

Billed as a cousin to the Hubble Space Telescope, and something of a descendent of that observatory, the Wide Field Infra-Red Survey Telescope (WFIRST) will use a very similar telescope system as Hubble, with a 2.4m diameter primary mirror, but with a shorter focal length. This, coupled with no fewer than 18 sensors built into the telescope’s camera (Hubble only has a single sensor), means that WFIRST will be able to image the sky with the same sensitivity as Hubble with its 300-mexapixel camera – but over an area 100 times larger than Hubble can image. To put this in perspective: where Hubble can produce a poster for your living room wall, an image from WFIRST can decorate the entire side of your house.

This wide field of view will allow WFIRST to generate never-before-seen big pictures of the universe, allowing astronomers explore some of the greatest mysteries of the cosmos, including why the expansion of the universe seems to be accelerating. One possible explanation for this speed-up is dark energy, an unexplained pressure that currently makes up 68% of the total content of the cosmos and may have been changing over the history of the universe. Another possibility is that this apparent cosmic acceleration points to the breakdown of Einstein’s general theory of relativity across large swaths of the universe. WFIRST will have the power to test both of these ideas.

Gabrielle Riel to semi-retire from SL, St. John estate to close

St. John Parish

Long term Second Life resident Gabrielle Riel, founder and General Director of Radio Riel and owner of the St. John estate of seven regions, has announced she is to semi-retire from Second Life.

As a broadcaster and DJ, Gabrielle is well-known to many in Second Life, and her Radio Riel station is one of the most popular in Second Life, and one of the longest running, having celebrated its 10th anniversary of broadcasting in June 2017. Offering music covering a wide range of genres, Radio Riel is popular in the historic, fantasy and steampunk communities and well-known for their support of Relay for Life of Second Life and Fantasy Faire.

In 2013, Gabrielle founded the St. John residential estate of seven regions, which has proven popular with those renting there, building up a strong sense of community. Unfortunately, it is the part of her Second Life that is most directly affected by her decision.

Gabrielle Riel

“I want to make it clear I am not TOTALLY leaving SL!” Gabrielle told me. “Radio Riel will continue and I will still be coming in-world to play my gigs; I have four or five a month.

“I’ve always said ‘real life first, always’. It’s been my constant advice to everyone; now it’s time for me to take that advice.  I’ve been in Second Life for over eleven years now, and over ten of them have been on a professional basis: playing my gigs, managing the estate. It’s time for me to semi-retire, and that means I’ve decided to close St John.”

In order to try to minimise disruption for residents on the estate, Gabrielle intends to handle the closure in stages in order to give people time to arrange moving out without too much panic. To achieve this, she has set out a schedule of closures, and has asked that St John residents vacate their parcels as their tier expires, or no later than 12:00 noon, SLT on the following dates:

  • Friday, January 5th, 2018: Bayou St. John.
  • Sunday, January 14th, 2018: St. John Woods.
  • Tuesday, January 16th, 2018: Lake St. John.
  • Tuesday, January 23rd, 2018: St. John Parish, St John Maurepas, St John Uptown.
  • Tuesday, January 30th, 2018: St. John Islands.

She also notes that for those who have paid tier beyond these dates, refunds of any outstanding balance will be arranged and made, and she’ll contact those due a refund directly.

Given St John has always been a personal commitment from Gabrielle – a place of pure passion and love, as she puts it, from herself to those who have made the estate their home; she’s therefore – and understandably – unwilling to sell the estate on to someone else to manage, because and with the best will in the world, changes will inevitably come about.

That said, some of the regions will be offered for sale via the For Sale By Owner group in Second Life. However, anyone from the St John estate interested in purchasing one or more of the regions in order to continue part of the community, is invited to contact Gabrielle directly concerning possible sale, and she indicates she’d be willing help with landscaping, etc. The main caveats she has with any sale are that the regions will be sold clean – none of the current builds or landscaping will be included, and the buyer will also need to cover the cost ownership transfer and rename the regions they purchase.

St. John Bayou

“I agonised over this decision through many sleepless nights, but there are things happening in my real life that make this necessary for me,” Gabrielle explains, in discussing the decision. “I am closing the full estate because real life demands my full focus now; I’m not going to manage any sims, even a few … The reality is that I have barely logged-in to Second Life since July, and I’ve had to come to accept that is just the way things are … I have detested being an absentee landowner; I’ve hated not being able to update builds or landscaping or handle land administration.”

“I’ve tried to address everything about this decision within the audio,” she told me. “This really is a personal decision that I hope everyone will understand. But I do appreciate some of the residents of St John may have further questions. If they do, they can contact me via e-mail [gabrielle.riel-at-gmail.com].”

You can listen to Gabrielle’s comments in full below.

With thanks to John Brianna for the pointer.
