The Fire And Ice Grid have been subjected to a serious attack on our servers.

All data is securely backed up on disconnected media and is in the process of being restored.

Our apologies for the interruption in the normal service.

The main website is now back up, the rest of the grid will be back up as soon as the data transfer from the backup server is completed.

So far the website, blog forum and wiki are restored, regular updates will be added to our discord channel.

The Fire And Ice grid has implemented restart warnings when simulators (groups of sims) are shut down. Every minute, during the ten mins before a restart, residents on affected sims will get a popup.

How many times has the #Opensim community found out too late that their grid has no #Backup or can't deploy them? Events like this should never be; unfortunately, the opposite has been exact. See the blog for our methods.

Creating mega prims at the Fire and Ice Grid. A look at the opensim settings required and how to work around viewer limits using scripts.

https://blog.fireandicegrid.net/index.php/2020/04/27/creat...

Following our upgrade to 0.911 last week the Fire And Ice grid has now returned to using separate Robust instances.

This setup is a little more complicated, hence my decision to go with the simples setup for the upgrade. Multiple robust instances bring performance improvements in a number of situations.

We currently separate the grid user service, asset service and inventory service (the ones suggested on the opensim website). If anyone has experience of further gains for separating others I am interested in talking.

The Fire And Ice Grid are pleased to announce we have completed our opensim version upgrade. The opensim version upgrade to 0.911 forms part of our ongoing commitment to keep up with opensimulator developments.

The Covey Rez Pro system can be used as a basic Pack and Rez system as found in many rez boxes. However, it is capable of a lot more than just being a rez box. This system can record and rez sets of items. For example, you might have different sets of furniture for a room. With the Covey Rez Pro system you can easily and quickly switch between them. That is not restricted to just something room size. That could be entire regions if you wanted. You also can rez and de-rez individual items. In addition to this it is designed with nested rez box's in mind. For example, you could have one rez box which contains 10 rez boxes. Each one can be rezzed and then automatically moved into place. Then you could rez all the items from it, a set of items or a single item.

There is a full Inbound and outbound A.P.I. which will allow a multitude of other functions such as using it as the rezzing add-on for a vendor. It also allows automated collection and repositioning of sim vehicles without the need to use temp rez as is the usual case now. Everything can be automated and triggered by other objects in a sim. So, it can act as a full scene switcher / Holodeck.

There are two rezzing modes. Relative which is the typical method for a rez box where the items will move around if the box moves. It also has absolute positioning which will return the items to their original position on the sim. The system supports SIM's of any size and will allow you to rez all the way up to 10 km high. Underground movement is possible as well if your Open Sim server settings allow it. Full checks are made to ensure you cannot attempt to rez an item outside the sim boundaries.

The whole system has been coded from the ground up to be used in Open Sim. It is designed assuming that items will be left out. Usually rez systems run a timer to detect movement of the rez box. So does this system, but it can be turned off. The memory requirements have been kept to an absolute minimum meaning there should be no adverse effect on your regions for using the system and leaving objects rezzed. Listeners are only turned on when they are needed and disabled when they are not. There is also protection against script resets (this can happen if the scripts are turned off at estate level). Most other systems do not have this because they were made originally for Second Life where that does not happen.

Have as many rez box's out on one sim as you like. Box's owned by other people will not interfere with yours at all. With your own the only limitation is that only one rez system at a time can be set to record. Even that is made safe so that when recording is enabled on one system any others in the same SIM will have recording disabled.

Convenient recording modes allow you to automatically pick items up if your Open Sim grid allows it. Or if it doesn't there is a manual mode as well which supports testing items to see which ones you have recorded.

The system is NON-DESTRUCTIVE for your items. Because it was designed for Open Sim from the ground up, it uses note-cards to store settings and positions in your items. This means the item description remains untouched. Since many items use that for their own purposes it means you can pack many more items than you can with other systems. This is also one of the reasons you can have nested rez systems.

Like all rez systems packing and rezzing no-copy items can easily end up with you permanently losing the item. Covey Rez system pro protects you against this by detecting it and refusing to record the item. Of course you get notified. When you are packing items you also have protection against dropping a script into the same item twice. Should you do this, the duplicate script will be detected and removed.

There are many other features to help you along the way, keep reading to find them all or just dive in and have a go.

If you can not open the embedded notecard, they are all available in the Covey Rez Pro Documents box separately.

Covey Advanced Visitor Counter
======================
This system is the nearest you can get to a full web solution just using inworld tools.

At any time of the day, you can see a list of who has visited your region. You can also see the total number of visits and the total number of unique visits.

At the end of each day that days list is saved to a notecard, telling you the name and originating grid for each avatar that visited your region. Then at the end of each month all the daily notecards are collated into one notecard for the month. This happens every month until the end of the year. When the end of the year is reached all the monthly notecards are collated into one notecard for the year.

There is an admin notecard so you can add people who can access the information, there is also an ignore list in case you wish to ignore certain avatars. NPC's (bots) are always ignored

When someone walks through a prim containing this script it performs a scan of the whole sim. Additionally, it performs one every 15 minutes.

To use the system, put a prim just above foot level at your landing point, then stretch it a bit to allow for people teleporting friends in. Then simply drop the script into the prim.

If you move or resize the prim reset the script.

Caveats: This system requires the use of OSSL for writing notecards. It is also limited by the number of lines your allowed to write to a notecard in the opensim.ini file for the instance your region is running on.
