As many of you had seen a preview of Google Chrome OS on my blog about a month back. I am glad to announce that a beta has just been released to public. The announcement has been made on Google Chrome Website & can be found at:  Google Chrome OS Beta release announcement . Ah not to mention I love the idea of google providing a virtual appliance to run on VMware Player for people to try their OS without having to install it. I believe it is a quite smart idea & will help the testing to spread a lot faster. Ah they still offer an installable version of the beta though :). So enjoy the ride.

Google seems eager to obtain a share of the Operating system market & cut a bit of the large cake Microsoft was keeping for itself for a long time.

Google are currently working on a web focused Operating System. As the web applications seems to be the future, Google new OS might strike the market.

Would history repeat it self? & google hit Microsoft Monopoly like Microsoft hit IBM monopoly in the early 90s where Mainframes where the solution.

As the new google OS is based on Linux and revamped around their new browser Chrome I thought it might be worth showing the demo on here :). Check out a sneak peak of the most kept secret OS at the moment below:

The default user prompt on Unix is “$” and the root prompt is “#”. In this article you will find how you can change the prompt to display a lot of useful information. The same or other information can also be displayed in the windows title. The prompt is set by changing the PS1 environment setting.

Some examples:

1. Username in prompt
PS1=”$USER >”
Result: “user1 >”

PVMe supports PVM, but its internal structure is completely new. As it runs on a PVMe homogeneous platform (The IBM 9076 SP2), many operations are simpler.

The following are the outstanding differences between the structure of the PVM and IBM AIX PVMe.

• PVMe does not interact directly with TCP/IP to implement data communication between processors. For this,it uses the System Communication (CSS), communications software that runs on the HPS adapter. Data exchange always occurs between processes, without involving the devil.
• The PVMe daemon runs in a single node and not all participating nodes as PVM.
• An improved scheme for memory management of PVMe can also take advantage of memory resources efficiently.

A vulnerability in IBM AIX 5.x and 6.x has been found which could be exploited by a local attacker to access sensitive information.The vulnerability is caused by a bug in the ‘at’ (/usr/bin/at) as it does not limit the privilege to read certain files (It has root permissions). This could be exploited by a local attacker to read any file.

This vulnerability confirmed in AIX 5.2.x, 5.3.xy 6.1.x. Depending on the version and platform, it is recommended to apply the following patches available for download from:

The Open Source community should be highly proud of Ubuntu. It seems to be the distro which most worry Microsoft in the Desktop market which is Microsoft Lead market. Actually Microsoft has posted for “Director Open Source Desktop Strategy at Microsoft” at linkedin. I was suprised that Microsoft are looking to hire some one at that high level just to put a plan to compete with Ubuntu on the Desktop market. Seems the Ubuntu buzz is floating the market. With Ubuntu 9.04 approaching, Ubuntu has proven it self as a great Open Source alternative for Windows in the Desktop arena.

Let us know what do you think of Ubuntu in the comments area.

After the delay for releasing the new distribution of Debian, the mother of many distros, such as Ubuntu, Knoppix, or Lenny (Debian 5.0), it has finally seen the light.
