^^^^^THis avatar is a HUGE RACIST!! She will go to your grid and start trouble please BLOCK all of her avatars! Kat Mouse - Shayna Denver - KaT Denver- Heidi Denver - FYI HUGE HUGE RACIST* SHE HAS ALREADY BEEN BANNED FROM SEVERAL GRIDS DO NOT LET HER ON.. ALSO SHE MAY BE A LINDAKELLIE ALT! ALERT

This is a futuristic region fun for all. Plenty of freebies. Original creations from owners and items from opensim creators. Enjoy!

Christmas region brings the joy and colors of the season year round. Great Christmas music as well. Drop by for a little Christmas spirit before your day and adventures continue.

new items added
I have just added over 50 new items in " snoodle world " and its getting to the stage I am struggling to fit anymore things as the whole region is jam packed full !!! Of course everything is free but can you find everything?? look in all the nooks and crannies and you never know what you might find :-) come pay a visit to ' panthera grid ' and receive a warm welcome, but of course don't forget to tp to snoodle world.

I am looking for the grid listed above? I don't know of anything else that is there, but, someone has asked me to help him find it and I cannot seem to find it . . . not even on the map? If anyone has any ideas on how to find it, can you please get back to me either on here or in world at Digiworldz? I am PassionFlower Jumanji in Digiworldz ;) Thank You so very much ;)
ZetaMex and deceptive business practices
Deceptive business practices. When one calls a property a virtual reality ESTATE - REPEATEDLY - and a 4x4, this is a lie. A SINGLE REGION is a single region. I have had my account canceled. I'll be interested in see if if next month I am charged because apparently language and standard definitions are not to be assumed to be shared realities.

Anyone who was around and paying attention when ZetaMex was the ground zero of open sim drama (did it ever change) will not be surprised.
Why Can't I Post An Event?
I tried to post an event, but I don't see how I go about doing it? Anyways, I am a DJ and I plan to DJ at 3PM on Friday, February 2nd, 2018 with my Great Canadian Grid avatar at the Great Canadian Pub. Any help about posting this would be appreciated.
geneis metaverse changed gird name to gevolution
They moved here: http://logon.gevolutionworld.com:8080, if you are still interested.

It would of been nice if we had a notice, but once I found them and recreated my accounts my sim reappeared in the new grid.
Island Oasis is on OpenSim?
Today I ran across the Halloween region on the Island Oasis grid(created by Sophia Paolino). I thought Island Oasis was a closed world? Or are some parts accessible to OpenSim. I stopped playing Island Oasis cuz no one was there!!! How long has this been available?

Get ready for a fun, family friendly adventure! This ride features scripted NPC Wizard Battles and much more! Total ride time is approx 7 minutes.
Part of the That Place Amusement Grd!

See me after class !
Just to point out that the header on the page reading, "There are no news" is incorrect as news in itself is singular. So it ought to read :
"There is no news" ~ or it could use the multiple "There are no news items", either way would be correct.

Nestled amongst waterfall and flowers, overlooking a still, dark sea. Stairway to Heaven is a place unlike any other in our world.
At its heart rests a luminous bowl filled with gentle, shimmering water, adorned with white water lilies and crossed by a golden bridge — a symbol of peace and reflection. Rising above it, a spiralling golden staircase ascends toward the heavens, where a radiant Angel in white, wings spread wide, hovers in eternal welcome. A celestial light pours down from above, illuminating the path between this world and the next.
This is not just a build. It is a feeling — of stillness, of hope, of something greater than ourselves.
Come alone. Come to think. Come to remember someone you love.
Stairway to Heaven is open to all residents seeking a quiet moment of prayer, meditation, or simply a place to breathe. There is no noise here — only light, water, and the gentle promise of peace.
You are always welcome. 🕊️

Notes on User tracing and fingerprinting.
Firestorm and other viewers send identification information to grids whether you login to home, or teleport to another remote grid.

This includes your IP address, your Mac address (unique identifier assigned to a network interface), and "Id0" which is a hash of the serial number on your harddrive (plus other system information). It's a hash so it doesn't send your actual serial number.

How can these identifiers be used? They can be used to enhance blocking capabilities, such as disruptive users with bad intentions. IP based blocks/geofencing is not reliable. The Mac address provides an additional level of blocking, since the Mac does not normally change even if the IP address changes. The Disk serial adds another layer. The serial number would normally be the same no matter what viewer is used. Presently Firestorm/other viewers do not use CPU serial, motherboard serial, or TPM, or other hardware identifying information to calculate the hash.

Ways users can protect privacy and circumvent tracking.

There are software applications that can randomize your Mac and also disk serial number.
Note that changing your disk serial number can possibly cause issues with the operating system function and other applications.
Changing the Mac address on a Linux computer network interface is trivial.

Using a VM/Virtual Machine - typically VM's randomize the Mac and also there is usually a way to set it. But you'd want a good VM with GPU passthrough to get good FPS on OpenSim, like a KVM with VFIO. Using a VM can also make it easier to randomize the disk serial.

However, probably the best bet is to compile Firestorm from source (github) and modify the indra/newview/llapviewer* for your platform (like win32) and change the function generateSerialNumber(). you'll also find it easy to change the Mac address sent by modifying the Firestorm code.

For the IP you can use a VPN or something or perhaps your grid offers a direct wireguard vpn connection like my grid Holoneon. You could also use Tor onion router but the latency isn't ideal.


If you run your own grid for other users you should note that collecting Mac/disk serial number hash is possibly covered under GDPR regulations (and other rules) and possibly should be specified in your published privacy policy. Check it out!

Opensimulator automatically captures the viewer id information sent and uses it to authenticate user activity. This happens in Gatekeeper.

You can add a little module to store that in a database if you want to identify problem users.

schema
