Determining the Memory and Disk Space on a Solaris System
If you need to determine the amount of memory in a Solaris system,
you can use the
command. The second line of output will
show the amount of memory in the system.
System Configuration: Sun Microsystems sun4u
Memory size: 384 Megabytes
System Peripherals (Software Nodes):
Or you can use
prtconf | grep Memory to get just the amount of
memory in the system.
If you need to determine the disk space in the system you can use this
BASH script to display the disk
space in GigaBytes (GB). You may need to modify the first line in the script to
point to the actual location of bash on your system, e.g. /usr/local/bin/bash on
Solaris 2.7 systems. The script uses the prtvtoc command and is based on the
BASH script provided by Sandra Henry-Stocker, ITworld.com in an article
Calculating overall disk space
published on December 23, 2004 on ITworld.com
. A full explanation of how the script works is available in the article.
The script must be run as root. To use the script, issue
chmod 700 soldiskspace to make the script executable.
/dev/rdsk/c0t0d0s2: 8 Gbytes
TOTAL: 8 GB

An alternative method of determing the disk space on a system is to use
iostat -En. Using that command on the same system as used in
the example above shows the disk space in the second line of output below.
The command also shows the manufacturer and model number for the CD-ROM
drive in the system. The size value should be ignored for the CD-ROM drive.
# iostat -En

Maintaining Wikipedia's Accuracy
There was an article on The New York Times
website today, titled
Growing Wikipedia Revises Its 'Anyone Can Edit' Policy
the way Wikipedia maintains the accuracy of its contents.
Wikipedia is an online encyclopedia
maintained by volunteers, which provides information on a multitude of
topics. It is a free alternative to other online encyclopedia's, such
as Encyclopedia Britannica.
Wikipedia allows anyone to edit most articles. So how does Wikipedia
prevent articles being defaced by online vandals who can think of no productive
way to spend their time or those with an axe to grind. It does so through
volunteer administrators who help maintain the quality of the information
on the website.

John Glenn Versus Howard Metzenbaum
I received an email that was purportedly based on comments by Senator John
Glenn of Ohio comparing the lives lost in the war in Iraq to casualties in
previous wars fought by America. At the end of the message was an exchange
between Glenn and Howard Metzenbaum, which purportedly occurred
on the floor of the U.S. Senate.
Unlike some such email messages, there was some truth in this message, but
also a fair amount of distortion and misattribution of comments.

PBS Distribution of TV Programming over the Internet
Robert Cringely's June 8 column,
Local Heroes: Could the Key to Successful Internet Television Be...PBS?
suggests that PBS
a good conduit for distributing television programming over the Internet, i.e.
IPTV, for not only their own programming, but for commercial programming as
He suggests that PBS affiliates could establish relationships with the
ISPs in their area,
colocating servers at the ISPs, which would distribute the programming
to the ISPs' subscribers.
