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 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.

Ah it seems virtualization is what going to unite the largest competing vendors. Yes, I am talking about Microsoft, Redhat, and Novell. Not too long back Novell who purchased SUSE has got in an agreement with Microsoft in regards of Virtualization. So with SUSE making the lead seems REDHAT is going the same route as well. I guess there is things where the big players in the IT market have to get a long, and virtualization seems to be  one of the biggest at the moment.

Redhat has surprisingly announced the joint of Microsoft in the virtualization market, and they will provide a validation and certification programs for virtualization solutions. As Redhat announced a good validation & Certification program will allow the customers to deploy a heterogeneous solutions from Microsoft & Red Hat. It seems in few years virtualizations will unlock the boundaries between many competing vendors.

The next version of Ubuntu, whose development has reached the alpha stage 4, is surprisingly fast compared to its predecessor and Ubuntu 8.10 even without implementing the filesystem EXT4.

You can notice the speed difference from the moment you boot up the system. On our test machine Ubuntu 9.04 were able to boot up in just less than 20 seconds where Ubuntu 8.10 required just a bit more than 27 seconds on the same exact system. Ubuntu 9.04 seems to further highly enhance the I/O operations by as much as 20% from Ubuntu 8.10. Further more compilation from source code was more efficient on Ubuntu 9.04 than Ubuntu 8.10 by almost 19%. Our egg drop compilation took around 5 minutes less than it took on Ubuntu 8.10 with the same hardware.

Most companies these days restrict their internet access by forcing the usage of web proxy. If your company is forcing a proxy policy & you are running Redhat/CentOs/Fedora you will have to update your yum.conf to be able to update your desktop or server using yum over a proxy connection. Luckily setting up yum to run over a proxy is an easy task. below is the few steps you need to follow to establish just that.

Edit the file /etc/yum.conf and add the following lines:

  # The proxy server - server: port
  proxy=http://proxy.mydomain.com:3128
  # If proxy authentication is required
  proxy_username=yum_user
  proxy_password=yun_user_password 

The next step is to declare the variable http_proxy to run
when the yum rpm get executed to avoid the below error:

warning: rpmts_HdrFromFdno: Header V3 DSA signature: nokey, key
ID e8562897

To declare the variable http_proxy run:
