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 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?

comment What is fedmsg?
If you want to create something that listens to this activity, because you want to make a service that reacts to it in some way, or if you want to display statistics, you might want it installed, but otherwise, you really don't need it.

comment What is fedmsg?
@HarryWeston It doesn't ease package installation. It's used in the Fedora Project infrastructure so our different services can communicate to each other. For, every time a package is built, a message goes out saying who was responsible. One consumer of those messages is the Fedora Badges system, where they are used to award the If you build it... or What goes up... (must come down) badges to deserving users.

comment Installing iPython3 Fedora 20
FWIW, here's the tracking bug to updating to the newer ipython version in Fedora. If anyone wants to help out with this, I'm sure help would be welcome. bugzilla.redhat.com/show_bug.cgi?id=1006575

comment Why can yum still not update GCC 4.9.0?
If you really don't want to wait, consider switching to Rawhide, Fedora's continuous development release. It's not quite for the faint of heart, as sometimes things break, but that's the price of following the latest versions of things. (Disclaimer: I'm a Fedora developer. Also, more on Rawhide in the middle of this blog post I wrote.)
