Looking Ahead Week 32

Viewer Development

Viewer development process changes a bit. The Lab is changing the release process a touch too. More likely now we will see Third Party Viewer (TPV) Developers releasing betas and development viewers rather than production releases, the later being the stable version intended for general use.

The Lab has gotten much more metric driven about their crash rates. They are putting more effort into holding the lid on the Linden Viewer crash rates. This means code in the Beta and Development viewers are likely to see more testing and changes before new code makes it into the release viewer. That is good thing, but may slow things down.

Groups Editing Update II

by

Baker Linden gave us another update on how he is coming along with fixing group editing. There is hope but there are some issues to be solved too.

Baker said, “I’m in the middle of debugging the server code.

For announcements, I’m pushing legacy viewer support to the back burner.  The new group data format is similar enough that some things should show up in the group list (I haven’t tested that yet), but not everything  [will show up] ([i.e.,] currently group roles, and potentially other pieces of information).

 I could also be lying to myself about that as well; it may be totally incompatible — I’ll have to wait and find out when I get to the viewer side of this. This is why I’m pulling it off the list — if it works, fantastic; if it doesn’t, then it doesn’t.

I think it’s not worth the time spent to support legacy viewers; I’d rather ship the fix, allow TPV to support the new format and allow people to actually use this feature. It’s just a matter of reformatting the data, but that extra work means more time spent on it and not delivering the feature.

 I doubt it’s going to be that big of an issue.”

Remember. He is new.

Second Life Viewer Change

by

Hypergrid Business has an article by Maria Korolov titled: Linden Lab cuts viewer link to OpenSim. This is about a rather subtle change in the Lab’s viewer that creates a not so subtle result.

Error Message from Version: Second Life 3.4.1 (262681)

To use the viewer on a grid other than the Linden grids a small change is made in the desktop icon used to start the viewer. If you right click on the icon and select Properties, you will see a field labeled: Target. It is in the Shortcut tab. The instructions there tell the computer how to start Second Life™.

Knowledgeable computer users will recognize the text as a command line instruction. If you open a command line window you can type in or paste in the text you find there as a command and Windows will start and run the viewer.

#SL Direct Delivery & Market Place

by

I used to write regularly about Direct Delivery (DD). But, there just isn’t much known about what the Commerce Team is doing with it. None of the Lindens outside the Commerce Team know whats going on, or they won’t talk about it if they do. So, about all one can say is it sort of works and the Lab is working on it.

Merchants are frustrated. A number of them have gone looking for a better choice. Some have closed up shop. But, no one has built a better market place system. There is certainly a demand for a better market place.

My first article that carried the term Direct Delivery was published in mid April 2011: SL Market Place – Direct Delivery. Direct Delivery was on the verge of starting closed beta. In October of 2011 DD made it into the Le Tigre release channel in the main grid. (#SL Direct Delivery in Testing) In mid January 2012 DD made it to Open Beta testing on the Preview Grid Aditi. (Direct Delivery Beta Post) DD launched in mid March 2012. (Direct Delivery Launches)

Virtual Landmarks

by

There is a new proposal on the Linden table. It comes from Toysoldier Thor and can be found in the JIRA as: SVC-8082 – Proposed Global Service for SL:  VIRTUAL LANDMARKS & VLM Mapping Services.

The Problem

Consider what happens when you have a home or shop in-world and your landlord decides to return the land to Linden Lab or for some other reason you have to move. The land is either going to disappear and all your stuff will be returned or your shop or home will be gone. You find a new house, apartment, and/or shop. There is little that can be done to stop that process.

But, consider. What about all the Landmarks that point to your shop or whatever that no longer exists? What do you do with the dozens to thousands of links in the Market Place to your non-existent shop? Did you know there is no easy way to just change the landmark you have included with a product you have for sale? You have to reload the entire product package.

#SL Group Editing Update

by

You probably know that editing large groups over about 10,000 is a big problem. I mention it in #SL Server News Week 31.

Baker Linden is working on getting group editing fixed. At this Friday’s Server/Scripting meeting he had this to say:

I’m almost finished with the server side fix for large group management. I’m hoping that the changes I’ve made will also be compatible with legacy viewers (they -should- be). If the data changes, I’ll make sure to hit up a TPV user group before it goes live to let them add the necessary changes to their group UI windows. With my own tests, I’ve managed to successfully get data for the largest group on Aditi (~40k users) without problems. It takes a couple minutes the first time you do the query, but after that it takes around 3-5 seconds.

I ended up changing the way that works, from when I said that. I’m hoping I can get that data sent across with everything else. The biggest change I’ll be making will be instead of sending all 40k users at once, I’ll be sending groups of members to the viewer. It will make sorting more difficult, as you may get 40 “groups” of 1k members each (for example) this way, we also don’t push upwards of 5MB through UDP. Actually, the way the data is formatted, there will be changes (I’ll make sure legacy viewers get the data the way they’re used to).

It may move to that [HTTP protocol], but right now I have a UDP connection that transfers the data.
