Google Chrome OS beta is ready to download

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 Chrome OS preview

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:

Differences between PVM and IBM AIX PVMe

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.

IBM AIX 5.x and 6.x revelation of local information via ‘at’ command

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:

Ubuntu Desktop apparently frightens Microsoft

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.

Debian 5.0 Lenny, finally ready. Happy 15th Anniversary.

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. Few days ago they replicated the distro to all the mirrors so that you can now celebrate the 15th anniversary of the distribution. Download is available by both HTTP & Torrent.

After 22 months of development Debian 5.0 has been presented. The free operating system supports twelve arquitcturas constant. Debian GNU / Linux is a free operating system that supports a total of twelve architectures, Sun SPARC (sparc), HP Alpha (alpha), Motorola / IBM PowerPC (powerpc), Intel IA-32 (i386), IA-64 (ia64) HP PA-RISC (hppa), MIPS (mips, mipsel), ARM (arm, Armel), IBM S/390 (s390), and AMD’s AMD64 and Intel EM64T (amd64). Apart from the most popular desktop environments: KDE, GNOME, Xfce and LXDE.

Microsoft and Red Hat, united by virtualization

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.

Ubuntu 9.04, 20% faster than Ubuntu 8.10

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.
