That commitment
has also encouraged involvement from the kind of people who are willing to contribute back
to that community in all kinds of ways. The willingness of Linus to incorporate code from others
in the Linux kernel has also been critical to the success of Linux.
The following sections characterize Linux and the communities that support it.
Features in Linux
If you have not used Linux before, you should expect a few things to be different from using other
operating systems. Here is a brief list of some Linux features that you might find cool:
No constant rebooting??”Uptime is valued as a matter of pride (remember, Linux and
other UNIX systems are most often used as servers, which are expected to, and do, stay
up 24/7/365). After the original installation, you can install or remove most software
without having to reboot your computer.
Start/stop services without interrupting others??”You can start and stop individual
services (such as Web, file, and e-mail services) without rebooting or even interrupting
the work of any other users or features of the computer. In other words, you should not
have to reboot your computer every time someone sneezes. (Installing a new kernel is
just about the only reason you need to reboot.)
Portable software??”You can usually change to another Linux, UNIX, or BSD system
and still use the exact same software! Most open source software projects were created to
run on any UNIX-like system and many also run on Windows systems, if you need them
to.
