What is User-mode Linux?

User-mode Linux is a patch for the Linux kernel which allows an executable binary to be compiled and executed on a host Linux machine. The kernel can be assigned virtual resources, including a root filesystem and swap space, and can have a hardware configuration entirely separated from that of the host.

A brief history of Linux

linuxThere are approximately 180 million Web sites worldwide. It is growing every day, and all they need servers to host them, and very few website owners want the hassle of hosting management in private. Web hosting, serving the world your web pages, plays an important role in maintaining a viable Internet.

Ports: UML/ppc

Many people saw the announcement by LynuxWorks of a ppc32 port of UML. I subsequently received the code, in the form of a 2.6.0-test9 kernel tarball, rather than in the form of a patch which is the standard currency in the Linux world. The tarball is available here. It is not a complete kernel tarball, which will complicate any effort to generate a patch from it.


So, it would be a nice project for someone to clean out the cruft, and generate a clean patch so I can see what happened there, and how to merge it.


I don't want to seem ungrateful to LynuxWorks for the carping above. This is a useful piece of work, and was probably a lot of work. It just would have been nice to get a clean patch so I could see what they did.

On the ppc64 front, IBM sponsored a contest to port various SourceForge projects to ppc, one of which was UML. There was one entry, from Noah Misch at CalTech. He did not manage to get it finished (or even compiling), so, unfortunately, I couldn't in good faith tell IBM that he did it, and get him his G4. Sorry.

He was good enough to send me his incomplete patch, which is available here for anyone who might want to pick it up and run with it.


Luca Bigliardi was good enough to poke through that tarball and make a patch. The 208M source tree is now a 260K patch. There are remnants of a LynxOs port attempt in this patch, which need to be separated from the ppc32 parts. The patch doesn't build, as the original tarball doesn't.

iPhone application development

It is amazing to see how science and technology has changed the way we undertake our daily jobs. Earlier we had to get assistance of the fixed line iphone whenever we wanted to get in touch with our friends or family members or in case they desired to contact us. It was not possible for us to get in touch with these folks, while we had been traveling or no fixed line telephone was accessible. All this altered with the evolution of the iphone.


Factors have altered quite a good deal since then. The modern generation mobile phones are extremely sleek and permit us to take pictures, watch video clips, hear music, surf the internet, enjoy games, and much more. You can avail these types of features with the help of specific programs embedded within the iphones or can be downloaded via the web and then installed. These applications may also be purchased by the end-user through application stores. Businesses that are into software development generate a tidy amount of money by marketing their software that delivers an extra characteristic on cellular phones.
