Decrease Number of Facebook Rooms

2011-09-29T18:59:00.002+02:00

Removed the per-profile and per-category rooms on facebook. Language dependent rooms remain.

This Site has not been abandoned

2010-07-19T17:10:00.004+02:00

Just in case you wonder if this site is still alive.

Nothing is happening here, because there are currently no changes in the global VPI configuration.

The configuration has been adapted to the quickly growing usage of weblin in late 2008. When weblin disappeared the configuration was frozen. We will continue to expand the VPI root configuration when the presence of more users demand action. Until then the rules developed in 2008 are just fine.

.com on muc1

2008-12-08T16:34:00.001+01:00

Moved all domains beginning with n-z in the .com tld to muc1.virtual-presence.org.

Moved some TLDs -> Muc1

2008-12-05T15:17:00.001+01:00

Moved all domains with the TLD .br, .de and .mx to muc1.virtual-presence.org

Per user rooms for highly frequented sites

2008-12-02T22:13:00.006+01:00

metroflog.com and fotolog.com had lots of avatars. They have been configured to use a room per user account. people visiting the same account will meet each other. But it will hopefully be much less crowded on the main page.

On the way, the "explicit entry" function has been fixed for the email services of yahoo.com, msn.com, and live.com.

.es -> muc1

2008-12-01T19:42:00.000+01:00

Moved all domains of .es to the chat server muc1.virtual-presence.org.

Name Hierarchy Letter C, conduit, ac-adapt.net

2008-11-11T15:18:00.004+01:00

- Added a "c" to the name hierarchy. required additional refinement in the name index
- http://search.conduit.com/ is now explicit enter only like google.com
- http://ac-adapt.net/denpa/ got a separate in the site http://ac-adapt.net/

Google India

2008-10-09T20:04:00.007+02:00

Too many people on google.co.in made Google slow. Applied the well proven "manually enter" button to google.co.in.

Reason: Google is a dispatcher. It can be regarded as street crossing where many people walk by and leave quickly. If you want to meet people there, then enter manually. But usually you just search and leave without much communication.

YouTube, Nicovideo

2008-10-09T17:47:00.002+02:00

Both video sites have been reconfigured to use a room per video. If you meet someone, then you know that the person watches the same video as you are.

YouTube

2008-10-04T20:32:00.003+02:00

There are 10 rooms on youtube in the video section. Rooms are currently assigned to segments of the video ID space by the leading letter of the ID. Four letters are combined into a room., e.g. a-d and e-h.

Yet, these rooms are already crowded and something has to be done. The question is now if the ID space is split up further, e.g. by single leading letter or even 2 letters OR if we jump directly to the ultimate destination and make a room for each video.

After all, virtual presence is about meeting people with similar interest based on the content. If there is a room per video, then you know that the person you meet watches the same video as you are. The perfect reason to talk.

Are we ready for that, yet?

5 rooms for nicovideo

2008-09-19T19:40:00.002+02:00

The japanese video site "nicovideo" has been split into 5 rooms. One for the home page www.nicovideo.jp and 4 for the videos. Relevant is the first number of the video ID (after the "/watch/sm"). People meet if they watch the same video. But the video watching crowd is distributed over 4 rooms for video ID starting with 0-2, 3-5, 6-7, and 8-9. Also, if the host name starts with anything except "www.", then this is interpreted as a country domain and taken into account. So, de.nicovideo.jp is different from www.nicovideo.jp. Please see the nicovideo.xml.

TLD style handling inside ccSLDs

2008-09-18T15:27:00.003+02:00

Some countries subscribed to SLD domains, like .uk, .in, .br. They introduce another level like ".co." (in .uk) and ".com." (in .br). But sometimes they also register directly under the country code. Example: orkut india is www.orkut.co.in, but century21india is www.century21india.in. So be it.

msn and y8.com, one.lt, miniclip.com, naza-klasa.pl, raidrush.ws

2008-09-14T16:26:00.002+02:00

4 random rooms for msn.com, y8.com, one.lt, miniclip.com, naza-klasa.pl, raidrush.ws

Facebook, Youtube

2008-09-11T18:27:00.001+02:00

More rooms for facebook and youtube. Now 5 international rooms plus 6 language specific rooms.

g-m.com -> muc1

2008-09-11T14:54:00.003+02:00

Moved all domains of .com with domain names starting with g-m to the chat server muc1.virtual-presence.org. This will distribute half of the load from all .com domains to the new chat server. Still more to come.

a-f.com -> muc1

2008-09-09T17:53:00.003+02:00

Moved all domains of .com with domain names starting with a-f to the chat server muc1.virtual-presence.org. This will move the load of 1/4 of the .com domains to the new chat server. More to come.

orkut.co.in

2008-08-09T17:02:00.000+02:00

As a high traffic site it gets a random-room config with 4 statically configured language independent rooms. First entry in the brand new SLD structure.

Structure for Second Level Domains

2008-08-09T16:58:00.004+02:00

A new folder hierarchy has been created for countries with a ccSLD.

UTF-8

2008-08-09T16:29:00.001+02:00

All data has been moved to UTF-8 format. There where still some files in good old ISO8859-1.

Added Common Configs

2008-08-09T16:27:00.004+02:00

A folder "common" has been added directly under the root folder. It is supposed to provide commonly used configurations in order to avoid duplicates.

hi5, yahoo, friendster

2008-08-09T16:26:00.002+02:00

High traffic sites got a random-room config with 4 statically configured language independent rooms.

Mapping API

2008-07-16T23:35:00.001+02:00

A mapping API is available at http://lms.virtual-presence.org/api/

Check the HTML form to learn about the parameters.

Root folder v7

2008-07-08T13:48:00.003+02:00

A new root folder has been added. The main difference are relative delegate URIs with "../" instead of absolute URIs as in "firebat-2.7.7".

"v7" is the new root folder. "firebat-2.7.7" is deprecated and now frozen. Future mapping changes will be only in "v7".

pennergame.de

2008-07-08T01:26:00.004+02:00

Due to popular demand, http://www.pennergame.de has been split into several categories. See the new config for more information.

Individual Rooms for Facebook Profiles and Apps

2008-07-06T01:11:00.004+02:00

Each profile and each app is now a separate room. While you will be missing the company, you will now know that the person you meet is on the same profile and is visiting the same user.

See the facebook configuration.

5 rooms 4 Youtube

2008-06-26T20:43:00.003+02:00

The Youtube site has been split into 5 rooms. One for the home page (www.)youtube.com and 4 for the videos. Relevant is the first letter of the video ID (after the "v="). People meet if they watch the same video. But the video watching crowd is distributed over 4 rooms for video ID starting with a-h, i-q, r-z, and the rest. Also, if the host name starts with anything except "www.", then this is interpreted as a country domain and taken into account. So, de.youtube.com is different from www.youtube.com. Please see the youtube.xml.

Even more Structure

2008-06-20T19:55:00.008+02:00

Two new toplevel folders have been added. There are now 3 hierarchical structures and the 2 toplevel files.

Toplevel files:

root.xml: starting point for all mappings
default.xml: a general fallback

Structures:

ip4: IP 4 adresses
tld: toplevel domains
name: global names which span multiple domains

The mapping starts at root.xml, then branches out to IP4 adresses or continues in the "name" hierarchy. If there is no name, then mapping is forwarded to the "tld" hierarchy. If no location matches then the general fallback (default.xml) applies. Each hierarchical structure has its own starting and fallback points.

Here is a sample mapping process for http://www.slashdot.org/

It starts at:

http://www.slashdot.org/_vpi.xml

...then uses these files in the global phase:

root.xml
name/_.xml
name/default.xml
tld/org/_.xml
tld/org/s/_.xml
tld/org/s/l/_.xml
tld/org/s/l/slashdot.xml

...until a matching location tag is found.

Removed Auto-Enter for heavy email sites

2008-06-05T13:57:00.003+02:00

Configured some heavy traffic utility sites so, that people do not enter automatically. There is an [Enter] button, if users really want to meet there.

Sites:

*.mail.yahoo.com
*.mail.live.com
*.hotmail.msn.com

Tag:

<delay sec="infinite" bypass="true">

weblin.com -> muc1.virtual-presence.org

2008-06-05T12:52:00.002+02:00

Moved all *.weblin.com rooms to the chat server muc1.virtual-presence.org. TTL has been set to 5 minutes days before. Users entering the pages are directed to the new server. Users already entered stay in the old room until they navigate.

Hierarchical folder structure

2008-01-29T17:04:00.014+01:00

Switched to the new hierarchical folder structure where a TLD has a folder and the domain is split by single letters. How many prefix letters will depend on the domain name density. We are starting with 2. Example:

root/
root.xml
de.xml
de/
_.xml
y/
_.xml
a/
yam.xml
_.xml

Also: a hierarchy for IP4 addresses:

_ip4/
_.xml
80/
_.xml
154/
_.xml
16/
_.xml
235/
_.xml

TLD files still contain the individual configs. They will be migrated to the folder structure on demand.

Topology tag

2007-05-18T17:37:00.009+02:00

Infinite delay for google

2007-03-17T12:40:00.002+01:00

Added an infinite delay with bypass option to the google config. Reason: too many users on google.com, google.de. Many start pages (Firefox) and people whi search something but without a common interest.

default-vpi.xml

2007-01-16T17:16:00.002+01:00

Delegate all default cases to a new default-vpi.xml. Added https with mappings to the same location names as http URLs.

The VPI files were not available, because a network switch was broken. Switch changed. Operation back.

www.*

2004-07-02T20:00:00.001+02:00

www([0-9]*) prefixes will be stripped from .com domains.

New root

2004-06-14T13:30:00.001+02:00

Created new VPI root without muc-strict tagging for all rooms. "org."-prefix for joint slashdot room in 2.5.2.

The network probem disappeared over night. Operation as usual.

VPI down

2004-06-11T22:00:00.001+02:00

Our ISP has a fibre problem and we get very low traffic trough. Now its Friday night and there is no one reachable. Clients have a hard time to get the VPI files.

Slashdot

The JSF set up an emergency chat server (atlas.jabber.org) to take the chat load. Thanks to pgm/stpeter for the quick action. Changed default chat server in VPI files to atlas.jabber.org. Because of the unresolved MUC-karma problem, all rooms marked as muc-strict which prevents bubble chat.

1st
