Lowlevel software tends to be written in lowlevel languages, such as C and assembler. Like said most of Xen is written in C, so you need to learn/know C. You should first start with learning programming with C language, and the generic concepts of computer hardware, operating systems, kernels, memory management, etc. Something like a hypervisor, or an operating system kernel, is a quite complex beast, so you should probably first start with something much easier and learn C properly in an easier project. When you know C and Linux/Unix internals well you can continue working on Xen aswell. -- Pasi > Cheers. > > > > On Friday, February 6, 2015 2:46 AM, Pasi Kärkkäinen <pasik@iki.fi> wrote: > On Fri, Feb 06, 2015 at 10:31:09AM +0000, Jason Long wrote: > > Can you tell me why Ocaml used?

They thought it was a good fit for the problem at hand. More than that (i.e. comparisons of the relative merits of various computer languages for beginners) I'm afraid is not on topic for this list. xen-devel is not a forum to learn about the basics of programming or software development. To participate effectively people are expected to have an existing basic knowledge in many of the subject areas surrounding computer operating systems and programming languages. I suggest you seek out a local computer users group (e.g. LUG), speak to an advisor at your college (or a local college if you are not a student) or seek out a more newbie orientated mailing list.
