I've been using Linux and Unix professionally since 1995, mostly in Linux-related sysadmin/systems architect jobs supporting academia. I generally know my stuff, but am very happy to learn something new and to be corrected when I'm wrong. Currently, I am the Fedora Project Leader.

comment Why does Alt+SysRq+B not always trigger while REISU do?
Yep! There are "gaming" or "professional" keyboards that do register all keys separately. Search for "n-key rollover", or NKRO. (Das Keyboard is one example. I have no affiliation with them except I love mine.)

comment How to install package via yum in Fedora
Please note that Fedora 15 reached end-of-life over two years ago, in June 2012. That means that security and bug fix updates are no longer produced. Please update to a current release. (Right now, F20 is your best bet!) Also, Fedora 15 was kind of a rough release, with early systemd and big changes to the desktop environments. Newer releases are a lot more polished.

comment How is it possible to do a live update while a program is running?
If you really want to do this with your own code, you might want to look at the programming language Erlang, where "hot" code updates are a key feature. learnyousomeerlang.com/relups

@MatheusSilva If this answer -- the direct, actual kernel parameters used! -- doesn't provide you what you need to know for your homework, then you need to clarify further what your homework actually asks.

/proc/config.gz isn't usually compiled in on RHEL kernels. (Look in /boot for the config-* files instead -- why take up memory when a static file will do?
