Good news for all Debian / Ubuntu Linux fans. Sun has started to offer Ubuntu Linux based servers. Sun has systems competitively priced for small and medium businesses. Ubuntu is based upon rock solid Debian core. Look like Red hat and Novell going to have some nice competition. Sun offers x64-based systems certified for Ubuntu Linux:
* x64 Rack Servers
* Blade Servers
* x64 Workstations
* Workgroup Disk Storage
* Tape Automation

This is yet another successful story for open source software. Sun has no database software to sell in a $15 billion market that Oracle leads, according to IDC study. Congratulations, Monty, David and the crew.
Now, Sun Microsystems, Inc. today announced it has entered into a definitive agreement to acquire MySQL AB, an open source icon and developer of one of the world’s fastest growing open source databases for approximately $1 billion in total consideration. The acquisition accelerates Sun’s position in enterprise IT to now include the $15 billion database market. Today’s announcement reaffirms Sun’s position as the leading provider of platforms for the Web economy and its role as the largest commercial open source contributor. From the official MySQL blog:
After all the industry speculation about MySQL being a “hot 2008 IPO”, this probably takes most of us by surprise — users, community members, customers, partners, and employees. And for all of these stakeholders, it may take some time to digest what this means. Depending on one’s relationship to MySQL, the immediate reaction upon hearing the news may be a mixture of various feelings, including excitement, pride, disbelief and satisfaction, but also anxiety.
Being part of the group planning this announcement for the last few weeks, I have had the fortune to contemplate the consequences during several partially sleepless nights (I usually sleep like a log). And over the coming days and weeks, I’ll provide a series of blogs with various viewpoints of the deal.
Check out what Jonathan Schwartz has to say about this purchase at official blog:
That in addition to acquiring MySQL, Sun will be unveiling new global support offerings into the MySQL marketplace. We’ll be investing in both the community, and the marketplace – to accelerate the industry’s phase change away from proprietary technology to the new world of open web platforms.

ZFS has amazing feature set and now it is ported to Mac
ZFS file system developed by Sun for its UNIX operating system. ZFS presents a pooled storage model that completely eliminates the concept of volumes and the associated problems of partitions, provisioning, wasted bandwidth and stranded storage. Thousands of filesystems can draw from a common storage pool, each one consuming only as much space as it actually needs. The combined I/O bandwidth of all devices in the pool is available to all filesystems at all times.
Apple has ported ZFS from Open Solaris to the Mac OS X platform. You can download ZFS beta version here (via ./).
Project Indiana is working towards creating a binary distribution of an operating system built out of the OpenSolaris source code. The distribution is a point of integration for several current projects on OpenSolaris.org, including those to make the installation experience easier, to modernize the look and feel of OpenSolaris on the desktop, and to introduce a network-based package management system into Solaris.
The resulting distribution is a live-CD install image, and is fully permissible to be redistributed by anyone. It will also have the capability for developers to create their own, customized distribution based on Project Indiana.
Now the first preview version is available. This is an x86-based LiveCD install image, containing some new and emerging OpenSolaris technologies. This may result in instabilities that lead to system panics or data corruption.
Among the features contained in this release are:
- Single CD download, with LiveCD ‘try before you install’ capabilities
- Caiman installer, with significantly improved installation experience
- ZFS as the default filesystem
- Image packaging system, with capabilities to pull packages from network repositories
- GNU utilities in the default $PATH
- bash as the default shell
- GNOME 2.20 desktop environment

I’ve already written about when a user logs in what files are updated in UNIX / Linux.
In this article, you will learn more about UNIX login process such as what happens when you log in, how the logins are recorded into the UNIX system, and how you can use that information to determine who is logged on currently and who has been logged on in the past. You could use a modified version of the Perl script, for example, to provide total user-time information and charge it back to a user or department. From the article:
Explore new ways to record UNIX logins and other system activities in a number of different logs, and take advantage of this information to monitor user usage. This can be helpful from a number of perspectives, either to use for chargeback reporting or just to get an idea of how busy and active individual users are on the system to help when planning and allocating resources.

You can use “type” or “whereis” command to find out which command shell executes and to print binary (command) file location for specified command.
whereis command example
Display ls command location along with man page path:
ls: /bin/ls /usr/share/man/man1p/ls.1p.gz /usr/share/man/man1/ls.1.gz
type command example
Find out which command the shell executes:
type -a ls
ls is aliased to `ls –color=tty’
ls is /bin/ls
