Second Life Bits Week 36

Loki Eliot has an article up on why we aren’t hearing much about Experience Tools or seeing much in the way of ‘Experiences’. See: Where are the Seamless Experiences?

SL Streaming

In an earlier post I wrote of YouTube Gaming. Below is a recording of someone using it and streaming motion-capture into Second Life™. Hamlet has a mention of it too: Motion Capture Dancing Streamed Live Into SL! The video is an hour and 42 minutes… I have video starting the stream where you can see the avatar following Jessyka Richard  as she does her thing.

All the details you need to connect up a system and do this are pointed to by Hamlet in another article: How to Connect Kinect Motion Capture to Your SL Avatar. It leads you to: Kinect, Rinions, and Second LifeContinue reading

Zombie Eye in Second Life

It isn’t contagious. This problem passed quickly, I think. I didn’t run into it, so it is hard for me to know. But, it revealed another part of how the Second Life™ system works.

Knowledge is not everything...

Knowledge is not everything…

Backend Serve updates – there are a number of backend services needed to support Second Life. When the Lab is changing/updating them they generally provide no public notice, unless users need to change behavior, like refrain from transactions or rezzing no-copy items (which hopefully is changing).  Continue reading

Second Life CEF Update Week 35

We don’t hear much about this Second Life™  change. But, Chromium Embedded Framework (CEF) is coming and will affect our use of Second Life in many ways.



The viewer currently uses Webkit, an old unsupported tech, to display a number of viewer panels (like Search). It is also the tech used in Media On A Prim (MOAP). It is a part of SL Televisions.  Continue reading

Second Life Icon Textures

You may remember that weeks ago a point came up about how the little profile icons used in chat are never flushed from viewer memory. The more people that enter chat the more memory is used and never released until the user logs off or memory is consumed and you crash.

Um certo cais – A certain pier

As tiny as they are they have a larger impact than one would suspect. The profile image has to be download and is the source from which the tiny icon is made. It is, as I recall, it is the memory for both images that is not released.

Last Friday word in the Third Party Developers meeting is Cinder Roxley started writing a fix. I would guess that we’ll see one this year, but I have no idea what Cinder’s schedule is like – which you should read as I have no real basis I can point to for that guess. I expect the fix would be tested in the Alchemy viewer before appearing in any other viewer.

For most, all this means is another memory leak is getting fixed and we will crash less often.

Second Life News Week 35 #2

From the Third Party Developers’ meeting last Friday we got some new information about inventory and the viewer caching system.

Second Life Inventory

The Linden engineers are still looking at inventory loss issues. A few weeks ago they asked for feedback from those losing inventory. How did you do that, type stuff. Ever since they have been working on fixing those things that lead to inventory loss.

One cause is apparently something to do with how inventory is organized. You may remember that one can be blocked from logging in by having too many items in a single folder. Somewhere above 5,000 items in a folder can be a problem depending on your connection and computer speed.

We (us users) have also learned that the entire directory structure is sent at login. Then the viewer uses that list of folders to pull the contents of the folders. Make over 200,000 folders and you too can block your login. It doesn’t matter how many levels of subfolders, levels do not matter, just the total count. If it takes too long to load the tree list, you are screwed. (I think it was Whirly that tested this.)

The Lindens are thinking it may be time to add some server side enforcement of how inventory is organized. We are talking rules to stop illogical arrangements, like NOT allowing more than 1 trash folder.

Also, they are changing all inventory operations to use the API calls for AIS3. They will be closing the other API calls. So, viewers not using AIS3 will break… some day. Not soon. This isn’t something that is ready to roll out next week. It is going to take some time, but may be this year.

Another reason for server side enforcement of inventory arrangement/structure is some third party viewers are using some code that is pretty bad. The Lindens were not willing to name names. It was understood in the Developers’ meeting which viewers those are. But, no one was talking. I guess it is a cast the first stone thing…

Also, they plan to do more validation of things being uploaded. Apparently it is possible to upload some things that have malformed data. As it is now much of the data is expected to be properly formed by the viewer. But, with open source viewers that cannot be guaranteed. So, they plan to add server side validation for the various data formats.

Another change is more of the Second Life assets will be delivered via the CDN (Content Delivery Network). Eventually everything will go through CDN; sounds, animations, etc. For now it is mostly mesh and textures.

Second Life Viewers Week 35

From the Third Party Developers’ meeting last Friday we got some news. Not much from the Linden side. I am often wondering if there is really so little for them to talk about in regard to Second Life™ or if the community is wearing them down and they are talking less as a defense. We have been down that road before.

RC Second Life Project Oculus Rift Viewer version – This view is often left behind. Oz describes it as being ‘preempted’.  They have more important things to do and spend time on those rather than updating this version. I suspect few people are using this version as the Oculus type headsets it is designed for are not yet in retail release.  Continue reading

Second Life Project Viewer version

This is a PROJECT viewer, meaning it is more crash and bug prone than the Release Candidate viewers. I crashed and hit 100% disk use with this version of the viewer almost always in the first 15 minutes. But, I wanted to see the new features. So, I keep re-starting it. Sometimes it runs longer than other times. I have yet to pin down what I am doing different between a quick crash and longer run times.

New Complexity Information

New Complexity Information

It is important to note that during this Project Viewer time that you can provide feedback to the Lab and they are much more likely to listen and make changes. After the features are in an RC viewer they are MUCH less likely to make changes. So, if you think you may have a grip or suggestion, get it to the Lindens (JIRA Feature or Bug Report).  Continue reading

Firestorm Experience 8/21 – Update:

I’m playing a lot with Firestorm Viewer these last couple of days. After a bit more use I am finding a few more things.

Yesterday I wrote:

After 30 minutes or so I start to get mini freezes and black screens. I get that with the Linden viewer too… this may be me and not the viewers.

I am seeing a few more people experiencing the same problem in FS Support. One was Windows 10 user who’s anti-virus was apparently the problem causing 100% disk use while the viewer ran. In Windows 10 the Task Manager has a resource monitor built in. You can see how busy the CPU, disks, network, and etc are. So, it is easy to check to see if you have resource over-use as a problem or performance issue.  Continue reading
