Ventrilo version 3(.03) on Gentoo (2009 temporary)

I love Gentoo, but sometimes getting the more recent software to work can require some work ...

In this case, I was trying to install Ventrilo on the gaming LAN here. It was working fine on a Windows box, but as that machine isn't always on, and I like to have standard server stuff running on the Gentoo Linux server(s), I decided to set this up on one of those on the LAN.

In Gentoo, getting and installing software is usually like this:

# qsearch ventrilo
media-sound/ventrilo-server-bin The Ventrilo Voice Communication Server

# emerge -av media-sound/ventrilo-server-bin [emerge downloads and compiles the app]
# etc-update [if needed, this merges config file changes into the current configuration]
# nano /etc/ventrilo/{config_files} [set up whatever default application config files there are]
# /etc/init.d/ventrilo start [then start the server program]

[if everything looks fine, add the server program to the default runlevel, so it loads automatically upon reboot]

# rc-update add ventrilo default

Unfortunately, after doing this, the Ventrilo server started fine, but clients could not connect. I eventually discovered that this is due to the current Gentoo Ventrilo install is still at version 2, and the Windows clients we had already installed and had working were for version 3.

Looking on Gentoo Bugzilla, I found this entry:

Which had an update ebuild for Ventrilo version 3, which had not yet made its way into the main portage tree, where all the current Gentoo packages are. So, I grabbed those files listed in the bug:

# cd (return to home directory)
# mkdir ventrilo (create a directory for the source files)
# cd ventrilo
# wget
# mv attachment.cgi\?id\=139774 ventrilo-server-bin-3.0.2.ebuild
# wget
# mv attachment.cgi\?id\=139776 conf.d.ventrilo
# wget
# mv attachment.cgi\?id\=139778 init.d.ventrilo

Milky Way faster and heavier than thought


WASHINGTON DC: The Milky Way is spinning much faster and has 50 per cent more mass than previously believed, increasing the chance of a collision with another galaxy, say astronomers.

An international team of researchers have used ten telescopes spread out between Hawaii, the Caribbean and the northeastern United States to determine that the Milky Way is rotating at a speed of 161,000 km/h faster than previously thought.

Gravitational pull

That increase in speed boosts the Milky Way's mass by 50 per cent, said Mark Reid, of the Harvard-Smithsonian Centre for Astrophysics, in research presented at the American Astronomical Society meeting this week in Long Beach, California.

"No longer will we think of the Milky Way as the little sister of the Andromeda Galaxy," he said.

The larger mass, however, also means that the galaxy has a greater gravitational pull, which heightens the likelihood of collisions with the Andromeda galaxy or smaller nearby galaxies, Reid said.

Gravity betrays black heart of Milky Way


Gravity betrays black heart of Milky Way

PARIS: Studies of the movement of stars provide the best evidence yet that a huge, gravity-sucking hole sits at the heart of our galaxy.

The observations, to be published in the Astrophysical Journal, also offer the best proof that supermassive black holes – among the most enigmatic and powerful forces in the universe – really do exist.

By tracking the orbit of 28 stars inside the Milky Way for more than 16 years, scientists in Germany were able to trace the most detailed portrait ever obtained of these invisible monsters.

Milky Way map shows complex outer galaxy


SYDNEY: The Milky Way is encircled by streams of stars in shapes resembling a “jumble of pasta” according to scientists examining data from the biggest survey ever made of our galaxy.

The sky was mapped by the Sloan Extension for Galactic Understanding and Exploration (SEGUE) survey, which will ultimately create a detailed 3-dimensional map of the galaxy, featuring 240,000 stars.

Ripped apart

The survey has revealed new details of streams of stars that wrap around our galaxy. Astronomers found 14 distinct stream structures, 11 of them previously unknown. Many are believed to be dwarf galaxies on the margins of the Milky Way that were ripped apart by the gravity of their larger companion.

Kevin Schlaufman, lead astrophysicist behind the work at the University of California, Santa Cruz, said the new discoveries were just a small fraction of the mysterious structures waiting to be found within the Milky Way’s more than 100 billion stars.

"Even with SEGUE, we are still only mapping a small fraction of the Galaxy, so 14 streams in our data implies a huge number when we extrapolate to the rest of the Milky Way," he said.

The SEGUE project is part of the ambitious Sloan Digital Sky Survey (SDSS), being conducted by the 2.5-metre telescope at the Apache Point Observatory in New Mexico, USA. Schlaufman presented the results of the project earlier this month at the SDSS symposium in Chicago, Illinois.

Hoard of supermassive black holes found

This artist's impression shows the thick dust torus that astronomers believe surrounds many supermassive black holes and their accretion discs.


PARIS: A haul of hundreds of expanding supermassive black holes have been found buried deep inside numerous galaxies on the edges of the universe.

The astounding discovery is the first direct evidence that most huge galaxies in the far reaches of the universe generated cavernous black holes during their youth, around 10.5 billion years ago.

Scientists generally agree that the universe as we perceive it came into being about 14 billion years ago.

"Tip of the iceberg"

The findings – reported in the November edition of the Astrophysical Journal – more than double the total number of black holes known to exist at that distance, and suggests that there were hundreds of millions more growing in the early universe.

"We had seen the tip of the iceberg before in our search for these objects. Now, we can see the iceberg itself," said Mark Dickinson of the U.S. National Optical Astronomy Observatory in Tucson, Arizona
