Olantica Grid

by

I got a note that a new grid is around. If you’ve been To Olantica grid tell me what you think of it in comments.

This is an OpenSim world. Other than that I don’t know much about it. However there is a web site with a bit more information. See: Olantica – Lost Wolrd. They have a currency  So, one should be able to buy and sell between the VW and RL. That also means one has to trust them with their financial information. But, they do have free accounts.

Read the ToS. It does not inspire me to buy currency.

To point your viewer to the world use these settings:

Grid Nick: Olantica
Grid Name: Olantica
Login URI: http://olantica.net:8002/

Login In Page: http://olantica.net/splash/
Helper URI: http://olantica.net/scripts/helper/

Second Life News 2013-1

by

There is not much news yet this year. But, there is a little. First there have been no rollouts to the main channel or RC channels for two weeks because of the holidays. Maestro Linden says the Second Life™ servers have not been bad for two weeks without restarts. Things do slow, but otherwise not bad.

First Meeting of the Year - Morris, ADITI.

Coming Up

Caleb Linden is working in the Phase II Multi-Threaded Region-Crossing code. Two weeks ago a pile on test was done. Some issues were found and fixes are in progress. If things go well, the code may rollout to an AGNI RC channel next week (2). I think that is pretty impressive. But, there may be some problems so, don’t get too excited.

Second Life and OpenGL

by

A question by Loki got me looking at the state of DirectX/Direct3D and OpenGL. We hear Windows runs games faster on Direct3D than on OpenGL. That is supposedly why Second Life™ viewers run slower, fewer Frames Per Second (FPS), than other games using Direct3D. But, some people say otherwise. One of those people is Steam or more accurately the online gaming company Valve.

Valve makes the Source Engine that runs Half Life 2, Left 4 Dead, and Dota 2. Valve is not a Microsoft fan, which I don’t find surprising as Microsoft is known for trying to make Windows a closed shop that keeps other gaming systems at a disadvantage. In testing in August 2012 Valve reported that OpenGL on Ubuntu ran faster than DirectX/Direct3D did on Windows. You can read more about that in: OpenGL is Faster.

This tells us it is not just OpenGL and Direct3D that solely control performance. The OS has quite a bit to do with it also.

Is 3D Safe for Kids

by

I was answering a question in the SL Forum about 3D and Second Life. The involved people seemed short on  info about how 3D works for single screens. So, I was looking for a good explanation of the state of the tech. I came across an article at Tech Crunch.

Title: A Guide to 3D Display Technology: Its Principles, Methods, and Dangers

The word ‘dangers’ caught my attention. How can 3D be dangerous? This is a 2010 article. But, it points out the nature of the human visual system and brain and what fooling it with 3D displays does. Something I had never heard of or thought about.

It seems people coming out of long 3D movies are having problems with depth perception. Oh fun! More incompetent drivers on the road.

The real problem pointed out is for young children. We really have no studies or solid data on the effect. But, the points made in the article seems intuitive, which doesn’t make them right. But, it is a serious consideration for those raising young children and exposing them to 3D TV and games.

Apparently this is enough of a problem that Samsung posted this warning on their site:

READ THE FOLLOWING WARNINGS BEFORE YOU OR YOUR CHILD USE THE 3D FUNCTION.

Update: See VR Matrix Disassociation from Real Life.

 

More Global Warming

by

The data Warmers use most often comes from the UN’s IPCC, International Panel on Climate Change. In an ironic twist 20+ years into the debate more and more of the data used by skeptics comes from… yep the IPCC. If you are one that believes manmade warming is killing the planet, your beliefs are likely being fed by the mainstream media and the UN. If you’re a skeptic, you are either believing your friends or you are digging through reports and skeptic’s web sites.

You could look up the 1990 IPCC report and compare its predictions for coming years. We now have 20+ years of actual data since the report was written to look at. We can see how well the IPCC did at predicting the future, not very well. But, then you would have to get into the data and see how the IPCC has been adjusting it. Start with SurfaceStations.org to get the background on why adjustments are needed and in which direction adjustments should be made.
