This month has been a treasure trove of such things here on gentoo-user.

If you have the time, trawl the systemd and grub2 threads for some
amazing tips.

The "Fonts and bad eyes" thread would also make a good insert - it
covered a very interesting area of less than general scope (but that's
what makes it so especially interesting - if you need to edit a console
font, the answer is in there)

I had no idea there was as many folks with bad eyes when I started that
thread.  It's will take me a while to try all the things recommended. 
Some days my eyes are somewhat OK but some days, they just plain suck. 
Text is really hard to read but even pics have some challenge to them. 

I thought the newsletter died.  When did it come back?  One thing I used
to like about them was warning of issues that were coming.  That helps a
lot.  Upgrade xyz, make sure to update configs BEFORE rebooting else you
get pieces.  That sort of thing was very helpful.

I skipped those threads because I don't use systemd and I'm having no
trouble with grub, but now I've marked them to go back to when I have
time.  So thanks for pointing me (and GMN and everyone) to them!

You can create a simple shell function like this:

whymask() {
    find /usr/portage/profiles/ -name '*.mask' -exec \
    	awk -vRS= "/${*/\//.}/ {
    		print \" \" FILENAME \":\", \"\n\" \"\n\" \$0 \"\n\"
    	}" {} + | less
}

You can do `whymask sys-kernel/gentoo-sources` to get reasons as to why
a particular package is masked; very handy to quickly check something
up, especially for USE flag masks which Portage doesn't explain.

You can do `whymask Gnome 3.12` to get the entire GNOME 3.12 mask,
piping it to `grep -v mask: > /etc/portage/package.unmask/gnome3` then
allows you to quickly update your GNOME 3.12 unmask; if you want this to
happen on sync, you can put this line in /etc/portage/postsync.d/gnome3
and make it executable such that it'll be ran after every sync.

The magic trick here is that awk -vRS= "/.../" matches paragraphs; as
the record separator is empty, it takes the blank lines.
