Second Life Faces Open Source Challenges

ruphus13 writes "Linden Labs has talked about Open Sourcing aspects of their platform for a while, but have not always followed through. Now, the OpenSimulator project has been gathering some solid momentum, and this was followed by an announcement by IBM that showed interoperability between OpenSimulator and Linden Servers. What this means is that you can use a Second Life client to log on to an OpenSim server. Beyond that, anyone can run their own server. 'Working with the protocols derived from the official Second Life client, and a knowledge of how Second Life works, these people have implemented their own compatible server code.' It is only a matter of time before users will be able to move profiles, virtual goods, and other elements of their 'second life' on to any server in a truly open world, thereby threatening Linden Labs' virtual world experience. With Google and Sun at the fringes of this space, things are going to get very interesting, virtually speaking."

      Well, as someone who actually runs a content development business, I can easily explain the returns to you.
      Second Life is great for Direct Marketing - users show very high levels of engagement. These days, brand managers are increasingly realizing that the $50,000 30-second spot is dead.

      Advertising is a lot like teaching - you have a message to convey, and you want people to get it right, and to take their time. Buying a slot of time on TV supposedly gets to a lot of people, but less and less people actually watch TV. The average TV watcher is 50. The average SL user is 30. Internet is picking up where TV left off, so Internet marketing becomes more and more important.

      Apart from that, TV time is too expensive. Television networks are expensive because they pay a lot for content. Second Life relies mostly on User Generated Content, so it's cheaper. You get rid of a middleman, sort of. You still have a (much cheaper) infrastructural middleman - Linden Lab - and of course you have a content / promotional team. But you can talk to people directly, and it's a far more personal and interesting experience than raw text IMs or emails.

      If you try to directly engage a consumer out on the street, they're going somewhere or just distracted, thinking about their own lives, you generally do not want to talk to salespeople on the street. In Second Life, people are there because they're bored, they have some free time and want to meet other people, or share fun experiences with others.

      A corporate-sponsored event can be a lot more entertaining than an amateur event. A single person will usually not build a whole sim and design/code up a companion website where people can have a fashion contest and submit their entries. We successfully reached about 75% of the target audience with one such event, and registered a total interaction time of 6 hours per person per week. That's like getting people to voluntarily watch 720 TV commercials a week! A banner ad usually only has a clickthrough rate of 0.1% at most.

      You couldn't do this on the web - there's no associated identity, so no fashion contest. You couldn't do this IRL - too much trouble to actually dress up and go somewhere, plus people are way too shy for that. Hence, Second Life!

      We also had a little Viral Marketing experiment, which was also wildly successful. On the web, you don't really have an integrated micropayments system. In Second Life, with the L$, you can have automated systems that instantly reward people for spreading leaflets. We ran out of money really fast, and will try to do something like that but with 10x more money soon :)

With the current oil madness, telepresence becomes more important and cost-effective. Academic research has demonstrated much higher levels of attention and message retention for students/trainees that took their classes in Second Life over the control group.

    The Second Life client is also a complete memory monster. On a 2 Gig system it will happily chew up over 600 megs, and completely unnecessarily since minimizing the app seems to kick in some garbage collection which slashes memory usage dramatically. The memory usage then rapidly starts to build up again.

The build tools should help you build things, not hinder you like the tools (and 10 meter object Restrictions) in Second Life.

  14. Worst programming environment EVAR! by Digital_Quartz · · Score: 4, Informative

    When I first heard about Second Life I was pretty excited about the prospect of using it as a teaching tool. My first real exposure to OO was LambdaMOO (MOO = MUD Object Oriented, and MUD = Multi-User Dungeon).

    LambdaMOO has a very nice object oriented structure, where everything in the universe is an object which inherits from some other object. There's object 1 which is called Object, from which you derive the base objects Room, Exit, User (User further split out into Wizard and Player), and so on. Every object in the world had a collection of "verbs" defined on it, which were essentially methods. Objects could call each others methods. It was a very nice environment for learning OO, because when an "object" is a "Tree" or a "Vehicle" it is a bit more concrete and obvious than when an object is a "TransactionProcessor" or a "DocumentFactory".

    LambdaMOO had no concept of a "class". Your user was an object which inherited from "Player" or "Wizard". But, adding new verbs to Player or Wizard would add them to all players and wizards, and verbs could be overridden on child objects, and the implementation was hidden, so you satisfy all the pilars of a traditional OO system.

    Now, we have Second Life, which COULD be a totally awesome tool for learning OO... except the scripting language is like a crippled version of Basic. Scripts can't call into each other so there's no code reuse. Scripts can't export any sort of interface (beyond the dreaded "touch" event) so there's no natural way to interact with scripts. Scripts are also hobbled by concepts like "energy" and various specific commands have other rate limits or other limits on them (which I understand the need for, I just wish they were documented). Let's not even talk about what happens if someone else picks the same "channel" as you to send inter-script messages on.

    Finally scripts are not OO in any way; no encapsulation, no inheritance, no polymorphism, no abstraction. Despite the fact that the world is literally made of objects, the development environment is not object oriented. It's crazy talk.

    It's outright painful to try and build anything of any complexity.

      You might want to look into Croquet then. It's based on Squeak, "worlds" can be distributed easily among various hosts, and it's open source. It's mostly designed as a collaborative / teaching tool. I'm always surprised that it never seemed to really take off.

      Possibly not visually as slick (although...) as 2nd life but has *much* more potential.

    "Nope. more often than not it's multiple sims running on an underpowered server. Most people buy the cheap-o option which is like a quad-core opteron with 24 other sims running on it.

    Umm, you have no idea what you're talking about. There is no "cheap-o option" if you want to connect to the SL grid - currently all server space on the main grid is leased directly from Linden Lab and each simulator has a processor core dedicated to it and runs on an individual server instance. Running Debian IIRC.

    Parent is absolutely right - a big reason SL has such inconsistent performance from sim to sim is that many of the builds are NOT done by professionals with performance in mind, and use needlessly costly scripts and high numbers of visible prims. Even more so, people will use insanely large numbers of insanely hi-rez textures, which not only adds download time but also works video cards much harder than a proper game does just in terms of shuffling gigabytes of texture data back and forth.
