how to linux kernel FOSS GNU

  • The kernel makes its services available to the application programs that run on it through a large collection of entry points, known technically as system calls.
  • From a programmer's viewpoint, these look just like ordinary function calls, although in reality a system call involves a distinct switch in the operating mode of the processor from user space to kernel space. Together, the repertoire of system calls provides a 'Linux virtual machine', which can be thought of as an abstraction of the underlying hardware.
  • An even less visible function of the kernel, even to programmers, is memory management. Each process runs under the illusion that it has an address space (a valid range of memory addresses) to call its own.
  • ...5 more annotations...
  • Note that specific application protocols such as FTP, DNS or HTTP are implemented by user-level programs and aren't part of the kernel.
  • the kernel provides a large collection of modules that know how to handle the low-level details of talking to hardware devices - how to read a sector from a disk, how to retrieve a packet from a network interface card and so on. These are sometimes called device drivers.
  • In contrast, modern Linux kernels are modular: a lot of the functionality is contained in modules that are loaded into the kernel dynamically.
  • This keeps the core of the kernel small and makes it possible to load or replace modules in a running kernel without rebooting.
  • This tells modprobe to include the probe_mask=1 option every time it loads the snd-hda-intel module. Some recent Linux distrubutions split this information up into multiple files under /etc/modprobe.d rather than putting it all in modprobe.conf.

  • : it’s about mirrorin
  • According to Wikipedia, “In computing, a mirror is an exact copy of a data set. On the Internet, a mirror site is an exact copy of another Internet site.” When you try to install a new package into your Fedora installation, either using PackageKit or Yum, it tries to fetch the packages from an Internet site along with the libraries and other software required for it, and install it on your computer. Now software like OpenOffice.org or OpenArena are very big and along with all their dependencies, the download size may be in the order of hundreds of megabytes.

FOSS Digital Divide

  • In Hindi, 'Gyaan' means 'Knowledge' but the word has roots in sanskrit, where it also is the root for both knowledge and meditative-awareness. Interestingly the same sanskrit word travelled to Japan, some believe in the days of Bodhidharma, and became the word 'Zen'.
  • Which is sad, because muft and mukt software can create a revolution in education today. It significantly lowers the entry-level price, thereby bridging the huge digital divide in India. IT students can learn how software truly works, as they have the freedom to study its source. A growing collection of muft and mukt software is available for all disciplines of education, at all levels. This helps further knowledge without penalizing educators and students. Most importantly, FLOSS in education ushers in a new value system in society: of building communities, creating and sharing wealth and knowledge. Indeed, FLOSS brings freedom to knowledge
