2016/02/16 by Nalates Urriah

Gravity Waves… Hi?

2016/02/152016/02/15 by Nalates Urriah

In 1915 Albert Einstein’s General Theory of Relativity predicted there would be measurable gravity waves. One hundred years later they have been detected. This opens the door to new ways of studying gravity and the universe.

Quoiting news releases:

The gravitational waves were detected on Sept. 14, 2015 at 5:51 a.m. Eastern Daylight Time (9:51 UTC) by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA.

My first question is what’s a LIGO? (lī•gō)We know what a laser is, a device that produces collimated, monochromatic, and synchronized light, synchronized with itself. The meaning is each light wave is in step with all its sister waves, all waves are the same length, and all are going in the same direction, parallel. (Reference)

Firestorm Team Thank You

2016/02/13 by Nalates Urriah

Jessica Lyon has posted on the Firestorm Viewer blog a thank you to the SL community. They have been raising funds mostly to pay for the Kakadu license.

Kakadu used to get lots of coverage in the SL blogosphere. Not so much anymore. Kakadu is the software Linden Lab and Firestorm developers license to handle compression and decompression of images.

You may not know that Linden Lab stores all images/textures in JPEG2000 format. The format offers the advantage of faster and smaller downloads and larger and slower downloads by having different resolution images efficiently stored in one image file. While the format is an ISO standard, the process of getting an image into and out of JPEG2000 format is proprietary. There are open source libraries developers can use to make and use JPEG2000 format files. They aren’t the same as Kakadu.

Photo No Longer Available – Flickr

I follow Dolls and Demons via Feedly. I adore the images Alles Klaar creates for her (I think her not his) blog. Today the article Escaping the Octopus has a Flickr image message rather than the intended image: This photo is no longer available. I was puzzled by its appearance as she is the owner of the blog and Flickr image. So, what happened?

Second Life: Third Party Developers’ Meeting 2-12-16

This meeting ran a little over 20 minutes. It was mostly status updates.

RC Second Life HTTP update Viewer version 4.0.2.310660 – This version has the HTTP, Co-routines, and Vivox updates. The HTTP updates were driving up the crash rate so in this version they are disabled.
