Fine-Tune The Kernel

Filed under

One of the advantages we Linux geeks like to claim over competing operating systems is the flexibility of the system. We're not talking about changing your screen saver--we're talking the guts of the operating system itself.

The most basic, core level part of an operating system is called the kernel. The term "kernel" is generally used to refer to the Linux kernel, but more accurately every OS has a kernel. This piece is slightly dated but has a still sound description of kernels:

The kernel is the first part of the operating system to load into memory during booting (i.e., system startup), and it remains there for the entire duration of the computer session because its services are required continuously. Thus it is important for it to be as small as possible while still providing all the essential services needed by the other parts of the operating system and by the various application programs.

As small as possible. That's where you come in.

  • Why viral licensing is a ghost
    According to an historical and widely shared distinction, present on Wikipedia and generally supported by too many free software advocates including some lawyers, “Strong copyleft” (sometimes renamed “viral licensing”) refers to licences governing a copyrighted work to the extent that their copyleft provisions can be efficiently imposed on all kinds of derived works, including linked works: the same copyleft licence becomes applicable to the combination. At the contrary, "Weak copyleft" would refer to licenses (that are generally used for the creation of software libraries) where not all derived works inherit the copyleft license, depending on the manner in which it was derived: copies and changes to the covered software itself become subject to the copyleft provisions of such a license, but not the software that links to it. This allows programs covered by any license (even proprietary) to be compiled and linked against copylefted libraries such as glibc (the GNU project's implementation of the C standard library), and then redistributed without any re-licensing required.
