I recently came across on one article about LiMo Foundation which is established by Motorola, Panasonic, Samsung , NEC, NTT DoCoMo, and Vodafone to develop Linux-based, open mobile communication device software platform.

From its whitepaper, It seems that the goal of Foundation Platform is to develop a Linux-based Mobile Application framework similar to Sun MIDP/CLDP for its Java2ME platform.

The Foundation Platform also define a standard way to represent GUI on mobile phone using GTK+ library. This is to encourage application interoperability between devices and to enhance mobile application user experience.

Hopefully in the future , we can develop a portable Linux application that can be compiled and run on any Linux mobile devices with little or no changes. This would encourage the FOSS to spread across mobile devices too.

Finally Linux kernel 2.6.20 is available! This release is interesting because it includes KVM (Kernel-based Virtual Machine), that enables you to run a virtualized computer with its own virtual memory, hard disks and other devices.

This means that you’re able to run other operating system under Linux using Virtual PC provided by KVM kernel driver. KVM has an advantage of being part of the Linux kernel and it uses processor extensions for virtualization compared to other virtual machine which uses emulation.

KVM uses modfied QEMU userland tools to manage its virtual machine and it has advantage over Xen because it can run unmodified operating system on its guest operating system. However, the current Linux release with KVM can’t be installed with Windows yet, due to a problem with the virtual APIC (bluescreen).

Although current benchmarks shows that KVM is still outperformed by Xen, Linux Kernel-based Virtual Machine seems to be a promising alternative to other virtulization solutions out there due to the use of CPU-level virtualization technology.

p/s: KVM requires you to have Intel and AMD CPUs that supports hardware-level virtualization.

I’m with Dreamhost since July, 2005 hosting my other websites, and now I use Dreamhost to host this blog as well. I decided to move my blog after much consideration that I dont want to risk my blog from being accidently shut down due to ‘my experiments’ on the VPS.

I love using Dreamhost because it offers easily managed and richly-featured shared hosting compared to other competitors. I only ever had 2 downtime experience since using Dreamhost and all of them are handled professionally by Dreamhost team. To help users get updated with the service status, Dreamhost maintains an offsite Dreamhost status which is fully accessible even when there’s outage at dreamhost datacenter.

Dreamhost offers Linux web hosting service at a very affordable price versus the services it’s provides. At Level 1 plan, Dreamhost provides you with :

• 185 GB Disk storage space
• 1.85TB Data transfer

• Ruby On Rails 1.2.1
• Jabber IM server hosting
• Unlimited Add on Domains
• Custom DNS management
• PHP4/PHP5
• SVN and CVS hosting
• Shell Account (SSH)

and all of these only costs you USD 119.40/year! I know that It might costly for those that only wants to try out or skeptical, but the company has a 97-day tryout policy on which you will have your money back if you’re not satisfied by their services.

Wait, how about it’s reliability ?
You can find out about Dreamhost reputation of reliability and uptime yourself by looking for independent reviews through the internet.

If you’re planning to get a better web hosting company for your website expansions, I would surely recommend you into trying out Dreamhost, because they have the longest money back guarantee too (97 days).
