OSGrid has a newspaper – Woot!

Kudos to Alyvaral Aeghin on OSGrid for taking an idea and making something of it. There is now a newspaper on OSGrid and it is called “The Ruth”.

The first issue is 8 pages and is available here for viewing. There are also newstand vendors (no charge) on Teravus Plaza, Yang and others. It is absolutely terrific to see more of our community on OSGrid that has been evolving for over a year and a half as we move forward in both helping to develop OpenSim by testing the latest SVN builds each day and developing our community at the same time.

SpeedBuild on Sandbox Plaza

snapshot_002

The second “SpeedBuild” contest was help on “Sandbox Plaza” today at 11:00AM PST (1900UTC) on OSGrid. The theme was “impossible things I would like to see fly”. Each week this SpeedBuild is occurring at the same time and place.

There were about a dozen participants including four builders creating a variety of, er, impossible things. Such as what appeared to be a stage attached to a steam-powered helicopter, a turbine powered, er, question mark, a dual-bladed watermelon helicopter and a flying tea service with horizontal stabilizers.

All objects are available to anyone after the hour is finished. This is a great chance to see, learn and teach some building techniques. While I was there, I had a chance to speak with a genie hovering nearby (in his oil lamp) and an advanced scripter with his sripting screen in mid-air in front of him. It is turning out to be very interesting to just watch what goes on each Sunday at 11:00AM PST/SLT (1900UTC) on “Sandbox Plaza”.

The sim performed well, no crashes, so the secondary goal of a small stress test while four builders were building was successful for OpenSim.

OSG Metaversity (second class meeting)

The second class for C# programming was help on OSGrid today at Teravus Plaza at 2100UTC. Ten people were there *and* use was made of Justin’s “Graffiti Board”, a white board script he kindly placed in the OpenSim library for all to use.

Most students were there an hour before the class started to discuss programming, *and* I heard some even asking about additional homework on the #osgrid-college IRC channel on FreeNode earlier. The enthusiasm is joyful, to say the least.

I hope that we can strive to use “Teravus Plaza” for various meetings around this time of the day everyday, both classes, question answer hours and other learning and sharing activities as the community using OpenSim continues to grow.

Since we are concentrating on using the SecondLife Official client, currently 1.21.6 and the Hippo also, this is a good time and place for us to get reliability and stress data for the use of a major plaza to help the OpenSim development along.

Vehicles in OpenSim

There are three types of vehicles in OpenSim. These three are:

Type 1: Non-physical vehicles moved with llSetPos().
Type 2: Physical vehicles moved with llSetForce().
Type 3: Physics vehicles moved with llSetVehicleType().

There has been significant success with Type 1, modest success with Type 2 and Type 3 is incompletely implemented at this point.

Type 1:
One can find an example of a Type 1 vehicle in the form of a tour bus and a taxi on the region ‘Port Edward’ on OSGrid. The tourbus runs a fixed route around the streets of the town and the taxi accepts commands to move around the town.

Type 2:
A couple of folks have reported success with motor cycles and boats.

Type 3:
The 10 or so llSetVehicle* functions are incompletely implemented. That is, they are missing the last connection to ODE. It turns out that ODE is a little different then Havoc in its definitions of joints and motors and this is waiting for a “zealot” to help move it forward.

In chatting with folks about Type 1 and Type 2, our current issue seems to be crossing a region with either type of vehicle. Either we loose the reference of the prim or script from the scene, we loose the physical state, or both.

It seems to me that setting up a number of copies of a simple script and run a fixed route vehicle at a region boundary while monitoring the consoles of the “from” region and the “to” region to create and add notes to Mantis is one of our best ways forward to figure this out. At this point, I would like to recommend a few folks on the various grids using OpenSim test this notion and help us get vehicles to where they can reliably cross a sim boundary and keep their state.

OSG Metaversity

The OSG College idea has now morphed into the “OSG Metaversity” on OSGrid.

Today, I attended the first meeting of a new C# programming class on “Teravus Plaza” in the small ampitheater. Normally, I am one of the most conservative members of OpenSim, but to see a teacher, SnowDrop Short gather 12 students together, form teams of three, exchange e-mails, assign a little independent study is so exhilarating that I needed to describe it tonight.

This class, partly organized by BlueWall Slade and others represents the instantiation of a dream I have had for two years now. That is, the use of OpenSim to teach others in a virtual environment useful lessons to help them grow and understand.

The class will be meeting regularly each Tuesday at 2000UTC, right after “Office Hour” on Wright Plaza. There is room for more students next week and I see C# as an extremely interesting skill to acquire. After all, we support C# scripts in OpenSim as well as LSL scripts. I see this as useful to those that might wish to create region modules also.

In fact, the admins in OSGrid discussed this after the course and we feel that we would like to dedicate the suffix “Campus” to any educational group or institute that would like to support learning on OSGrid.

This is an exciting thing to see happen, and it has the side benefit of demonstrating and perhaps stressing the sim with students on a regular basis as we work to increase the number of simultaneous avatars in a region.

OSG Community College

Normally, I am the quiet, factual team member, but today I was invited to an organizational meeting on “Teravus Plaza” for the “OSG Community College”. This is something very near and dear to my heart. That is, the use of OSGrid and OpenSim to teach others building, scripting, C#, mysql, php and other interesting subjects. So please pardon me if I bubble over a bit.

One of the most important uses of OpenSim is to allows folks to learn and teach. In our grid, we have two goals and they are:

1. To test OpenSim SVN on a regular basis on a large number of regions with Windows, Linux and Mac computers and report back via Mantis, IRC and e-mail testing results to help develop OpenSIm.
2. To build a long-lasting and diverse community with exchange of ideas, knowledge, social interaction, objects, builds and scripts.

One of the most important parts of the second goal is a way for folks to have a somewhat structured way to learn. The things that seem interesting to such learning at this time are: Building, Scripting, C#, OpenSim Configuration, MySQL, MSSQL, PHP, just to name a few that I think about.

With a group willing to start down the path of making a formalized time and place for teaching and learning, we are beginning to realize and important part of the second goal. I take my hat off to BlueWall Slade, Robert Omeganu, Garland Greene, Starky Rubble, Teravus, Tommi Laukkanen, Flash Lefevre, Praxis Thinker and Programmer Mohr for attending and inviting me to this wonderful meeting.

I hope this will grow into a campus on OSGrid and perhaps a plaza to support learning and teaching.

The next meeting will be on February 6th at 2100UTC, again on Teravus Plaza and will be 15 minutes of organizational discussion followed by a class on basic building.

Lets do it!!

OpenSimulator One Year Ago

As I reflect back on the state of the OpenSim software one year ago I seem to remember:

1. We were getting some physics functionality with ODE but all physics would run for maybe an hour or two and then tend to crash. Collisions were working, but physics was just barely hanging together.

2. Tedd Hansen had added scripting capability to OpenSim and we were struggling with the most basis llSay() scripts and the kan-ed list. We made an agreement amongst ourselves to enable the running water on Wright Plaza when we had a modicum of stability scripting even though we had the particle generator (mostly) working.

3. DeepGrid had been around for six months, OSGrid for five, OpenLifeGrid for two and CentralGrid had just started.

4. There were 1150 users on OSGrid (11,000 today) along with about 50 sims (1900 today) and on an average day 100 folks logged in (2200/day now).

5. The core developers were considering a field trip to see the Rex folks.

6. With more then 6 avatars on a sim, chat started doubling and the avatar tended to walk into the ground.

7. There were about ten active core developers and about another 40 active patch submitters.

8. We were headed towards our 0.5 release and thought we would probably get to 1.0 and Beta in about a year and a half, or about July of 2009.

I just thought some of these thoughts might cause a few to smile as we look forward from our current 0.6.2 which appears to be fairly stable and seems to be causing a buzz on the internet. We also have 90% of the LSL functions implemented and complex scripts can reasonably be expected to work. There are tens of thousands of OpenSim users and thousands of sims. We have 25 or so active core developers and probably another 125 submitting patches.

So, well done all. This is a time to grin, look around, enjoy a bit. I declare all bugs non-existent until next Monday at 8:00AM, when we can get hyper again after using the HyperGrid for OS2B.
