Original White Paper from Philip Rosedale and Cory Ondrejka on Gamasutra in 2003
A blast from the past.

Next OpenSim-In-A-Box version will include Megaregions

…yes, you heard right.

With the latest buzz on Adam Frisby’s success in adding Megaregions to the OpenSimulator (see the original posting here and more info there on Adam’s Blog) we decided to make a giant leap (sic!) by switching to an even newer version then we intended that will feature this great acchievement.

For obvious reasons we will wait a bit until it is more stable and documented but this whole development is very exciting … and Megaregions add up so nicely to Hypergrids .

Checkliste für Bildungseinrichtungen in virtuellen Welten

This just in via SLTalk, sounds very useful to me:

“Zusammen mit der MFG Innovationsagentur für IT und Medien haben wir eine Checkliste für Bildungseinrichtungen entworfen, die in virtuellen Welten aktiv werden wollen. Mit der Checkliste wollen wir interessierten Bildungseinrichtungen den Einstieg erleichtern, die die Mehrwerte virtueller Welten effektiv und effizient nutzen möchten.

Die MFG Innovationsagentur betreibt selbst einen Blog zum Thema Second Life. Außerdem dient die Agentur als Inkubator für kleinere Projekte in Second Life. Sie betreiben die Baden Wuerttemberg-Regionen, auf den Interessierte Institutionen mit geringem Aufwand virtuelle Luft schnuppern können. Über die MFG berichteten wir bereits des Öfteren.“

EnBW presents survey results in SecondLife

On Thursday July 23rd I will present the results of a survey at 19:00 MESZ (10am PST/SLT) on the EnBW Sims (http://slurl.com/secondlife/EnBW%20EnergyPark%20InnovationArea/104/58/28).

EnBW in SecondLife

Ausgerechnet ich blog es als Letzter.

Entgegen dem von der Presse allzu gern publizierten Trend, dass sich Unternehmen aus Second Life zurückziehen, ist man bei EnBW immer noch sehr an der SL-Community interessiert.

Am Donnerstag, dem 23.07.2009, werden um 19:00 Uhr im Auditorium des EnBW EnergyParks die Ergebnisse einer Online-Umfrage präsentiert.

Die Umfrage hat vor allem die Menschen hinter den Avataren beleuchtet. In dem Vortrag werden Antworten auf Fragen gegeben wie: „Wer nutzt eigentlich SL?“, „Werden Markenauftritte überhaupt wahrgenommen?“, „Was machen die Nutzer am liebsten in SL?“ oder „Wer flirtet lieber, Männer oder Frauen?“ (http://slurl.com/secondlife/EnBW%20EnergyPark%20InnovationArea/104/58/28)

Weitere Informationen zu der Umfrage finden sich nach dem Event unter: http://www.enbw.com/secondlife

‘Diget’ – Blood Glucose Meter from Bayer

What a splendid idea!

Bayer Diabetes Care (in the UK) announced a piece of hardware that can be used to and (quote) ‘rewards children for consistent testing’ – of their blood samples, that is.

Seems this gadget goes into the Nintendo DS and Lite in their GBA port (which the new DS version misses). The you insert your samples and get rewarded. I can’t see how this reward works in detail from their website though.

Now that’s what I call a Serious Game.

‘OpenSim-in-a-box’ pt2: enabling Hypergrid

OpenSimulator introduces a very cool concept called Hypergrid which is explained in more detail here.  In general it means that you can link regions from different grids together. The benefit is that you can teleport to regions from completely different grids, wearing your assets and inventory.

To make it easy for OpenSim-in-a-box users it is hypergrid-enabled by default, so since it is turned on at start up you only need to link the regions together:

• start up the region
• start up your viewer and log into your grid
• ’set home to here’ in the ‘world’ (this is important! or you can’t come back easily)
• now on the OpenSim console enter
  link-region 1002 1002 ucigrid04.nacs.uci.edu 9003
  to set the UCIgrid region to position 1002, 1002
• if you open the map now, you see a new region north-east
• teleport there by clicking on it (again: make sure you set your home position first)
• now you are on the UCI Hypergrid!
• to come back you need to teleport home

The regions ’see each other’ only on the map, not inworld.  So you can’t simply fly over there, you need to teleport.

• To unlink the region you enter
  unlink-region <regionname>
  on the OpenSim console (in this particular example unlink-region “Gateway 3000″ )

Of course you can also start up two (or more) OpenSim-in-a-boxes then you always have the chance to link back so that all regions are linked to each other. The coordinates should be consistent, though.

Regarding available Hypergrids: You can find a list of HyperGrid Nodes here but I am not sure which ones are active. We checked ucigrid04.nacs.uci.edu:9003 and it was working.

‘OpenSim-in-a-box’ pt1: setting it up in the cloud

So, how do you install the OpenSim-in-a-box into the cloud?

• goto the AWS console
• open the ‘Launch Instance’ dialog, select the public images tab ‘Community AMIs’
• search for OpenSim-in-a-box, and select the latest version

• run 1 small instance with your keypair and the default security group

• optional: get elastic IP
• optional: get a dyndns (or similar) entry that point so the elastic IP

Then you switch to your favourite ssh client and

• log in via ssh / putty
• wait for ’screen’ (this might take a minute)
• start ./bin/start_opensim.sh
• login via Hippo or Second Life viewer

Important: open the right ports for freeswitch and OpenSim

Yes, these are quite few (mostly freeswitch) but you need to do this only the first time. You do this in the security group section of the AWS console.

tcp: 22 for SSH
tcp and udp: 9000-9005
[Provisioning for 6 regions on 9000 - 9005]#

TCP

22 (for ssh)

UDP
16384 – 32768

TCP and UDP
5060
5070
5080
64738,64739

9000

(or 9000 to 9000+N with N= number of regions, provided you entered these ports while creating the regions)

[EDITED missing ports]

‘OpenSim-in-a-box’ pt 0: voices in the Amazon cloud

“Voice enabled Virtual Worlds for 10 cents an hour, ladies and gentlemen!”

For all of you who know how to handle Amazons EC2 – you only need this:

ami-cb7a9ca2

go and get it!

For everyone else I’ll explain what this is all about. In short: a ready-to-run voice enabled OpenSim without (too much) configuration hassle.

As I announced previously we today publish the ‘OpenSim-in-a-box’. The first version of this project is the idea to have a virtual world launch ready including voice support. You can use it to simply try out the OpenSimulator experience or to have a virtual meeting, conference, even concerts for more experienced users. After you are done you simply pull the plug on the instance and it is gone. Next time you need you start with a fresh instance and everything is exactly as it was from the start. It is not connected to a grid and non-persistent on purpose. However, it can be connected to a HyperGrid.

In this version OpenSimulator including voice chat without having to worry about source code, versioning or compilation.

It does however require a couple of things:

• you will need an Amazon Web Services account (which is simple to do if you ever bought something – a book comes to mind – at Amazon)
• you should be able to handle basic OpenSimulator server commands
• you should know how to handle either the Second Life Viewer 1.21 or the Hippo Viewer 0.5 or higher.

Note that you don’t need an SL account – probably everyone who can handle the viewer will have one, but you don’t need the account credentials for OpenSimulator.

It whole idea is based on the fact that setting up an OpenSimulator (a virtual world application server) with Freeswitch (a telephony plattform) can be somewhat tricky, although it’s documented very well (there is a german version, too). Especially thanks to both communities and developers writing the Freeswitch bridge (Rob Smart et al.)  we have a working albeit simple voice chat solution.

Some things you should know:

• for some reason the Linux ’screen’ takes it’s time to start up
• in the OpenSim Region start-up sequence you need to enter the numerical IP adress of the Amazon instance as the external IP address (or even better: get an elastic IP and a dynamic DNS service like DynDNS)
• Amazon will charge you 10 cents per hour (in the U.S., and 11 in Europe)
• voice support here is very different from voice support in Second Life; everyone in the region hears you can vice versa. The different avatars are practically in one telephone conference.

For future versions we plan to have some more features (not necessarily in that order):

• some initial content for the region
• most hopefully the possibility to be able to phone into the OpenSim (yes, from a real phone)
• web interface

In future postings I’ll explain how to set up Amazon in detail, how hypergrid works and how to have external chat enabled.

So, please try ‘OpenSim-in-a-box’ and give me some feedback on how it works for you! If there are problems, I’d be glad to help.

Dear M Linden …

or: a concept for Linden Lab.

… here’s an open letter.

I talked to several people about the following and my feeling is that this could be of some interest so I figured I better write it down.

I don’t want to sound like a used car salesman here but if I could make a suggestion to M Linden (you are actually quite responsive so I guess I can)  it would be the following:

Divide the existing Linden Lab construction into several companies.

To explain why I first enumerate these companies with some abbreviations and names:
1) LL: The ‘original’ Linden Lab (with focus on ‘Lab’) responsible for supplying technologies for persistent 3D virtual worlds.

2) SLGF: The Second Life Grid Foundation. The world that started it is the biggest grid, but should not be the only one.  These are the guys who run the Second Life Grid. They maintain a free, persistent virtual world without age limitations and free citizenship. I think this is close to the vision Phil Rosedale had initially.

3) LLPS: Linden Lab Professional Services, the guys who consult all the grids out there that are technically based on LL grid server. One of these grids is the Second Life Grid, but there could be/should be be several others.

Like the …

4) AGC: Adult Grid Corporation, the guys who run the adult grid. This would not be connected to Second Life (except that they use the same technology). Probably not too good of a name, I know, somebody can do better. I’d like to stress the following here: I think it’s important not to white list the innocent (that’s why I think the teen grid is not a good idea) but rather separate the adult content.

Why would this make things different?

1. The areas that these companies work in need to be addressed by completely different business models. You need to do different things when you run a service compared to provide the technology let alone make money from communities.
2. Service providers doing Internet business could walk up to their customers and sell Linden Lab technology without even mentioning Second Life – which would be badly needed in Germany for example.
3. The importance of different clients – preferably white labeled would be obvious then. And Phil mustn’t do this with his own league of extraordinary developers but as part of LL work (see also my note here).
4. The goals of Linden Labs (i.e. the different units) would be transparent and believable. Nobody needs to wear many hats.

Let me make some examples:

• IBM would talk to (the new, independent) Linden Lab to buy the technology for their customers since they usually would do consulting on technology on their own since they want to adapt that to there machines (like in hardware) or in their software (like Sametime 3D).
• An effort like OGPX (former MMOX as Infinity pointed out to me) would completely be led by the new Linden Lab which would be an independent  technology provider not a service provider with it’s own interests.
• There would be a distinction between the grid and the technology behind it (which would be very important for the success of the AWG).
• (the new) Linden Lab could think about OpenSourcing it’s server technology easier since there is no dependency into other business models anymore.
• If any of the grids goes down for some reason, the technology provider would still be there. And we wouldn’t have to wait another 7 or 14 years for virtual worlds to arrive.

The thing missing from a technical and a business stand point (apart from the no-brainers like stability) most badly IMHO is a hyper gridding mechanism. I say ‘a‘ hyper gridding mechanism because the one currently in discussion and partly implemented by the great Diva Canto/ Christa Lopes in the OpenSimulator community is not the only possible implementation. And maybe not the implementation that the current Linden Lab wants.

But now Linden Lab doesn’t push Hypergridding enough because it’s not in their business model right now … but you sort of need it for the Immersive Workspace Initiative.

So I guess, Mark, you are wearing different hats in this game now.
