Do you run yum update / upgrade regularly or not?

I added yum, but this can be related to any Linux system. I am personally working on CentOS7 now.

"For the most part, it's best to upgrade incrementally; that is, upgrade only those parts of the system that need upgrading, and then only when you think an upgrade is necessary. For example, if you never use Emacs, there is little reason to continuously install every new release of Emacs on your system. Furthermore, even if you are an avid Emacs user, there is usually no reason to upgrade it unless you find that a missing feature is in the next release. There is little or no reason to always be on top of the newest version of software."

So just dont run something like yum update && upgrade every now and then? I read to do it on some other website:

I don't know where you got the first quote from, but although its theoretically true, the point is that unless you know all the pkgs inside out and what their dependencies are, you're better off updating everything.

The main difference is that at home you can probably just got for it, at work you need to test the updates with your customisations and app code to be absolutely sure it won't break anything.

Note that if you stick to the official repos, the updates should be fine for that code/data (but it hasn't been tested against your own stuff).
Testing takes time, so you'd likely only do it on a regular basis eg quarterly.
NB: security updates may need accelerated processing.

I run Fedora with rawhide kernels - I'm always updating ....

Do the same on CentOS - probably just habit.

I update my systems regularly. Most of the time, I'm running either Fedora Rawhide or Ubuntu Development. If something breaks, I revert to the last working version. It's been a long time since updating a stable release has broken anything.

CentOS is very different than Fedora "rawhide" rawhide is the Next development
right now that is the PRE alpha of Fedora 24
that will have a TON of changes every DAY - if not a few times a day

there is a handy auto installed and auto turned on tool called "apper"

a notice will pop up on loging in if there are updates to install
and LIKE win7 and XP you can have it auto install or not

Now this is just MY!!! preferences so...
i find Apper rather annoying

not as FING annoying as Win7 !!!
but a bit annoying.

every few days i run zypper and update my opensuse13.2 install
