Hello all, recently I came across a very useful reference in one of the discussions that boots up a GUI Template Manager that allows you to see and download the OS repositories currently supported by Qubes:
qvm-template-gui
I have a feeling that there are probably many of these hidden little gems in Qubes and was hoping to start a discussion listing some of them.
Apologies if there is already a discussion/reference like this, but I was unable to find one 
there also qvm-convert-pdf too
i changed the tile to make it more useful
Just to clarify, this is a R4.1 feature.
Here’s one. In any standard Debian VM, open a terminal and:
rawtopgm 512 512 < /dev/urandom | pnmtopng > random.png; open random.png
If you look very carefully, you can see the Qubes encryption mascot. A true hidden gem!
where?
why would /dev/urandom produce any repeating pattern, let alone enough to reproduce a bunch of pixels in a specific way? Or am i missing something here.
We all have different senses of humor, I think…

Well it was either that or OP’s urandom was doing something very odd (and if that was the case, there could be questions around a security issue). So I personally err on the side of not using a made up security issue to make a random humour post posing as factual 
/goes off grumbling about the posting guidelines
@Plexus Thank you for looking after my best interests. It was in fact just my quirky humor as @brendanhoar pointed out. I promise this will be my last pareidolic joke until at least April 1st.
I like how these conversations often diverge off in unexpected directions 
There was a post I came across some time ago, not sure if it was here in the forums, in github or somewhere else, but the author was basically saying that a lot of the best features of Qubes are hidden in terminal commands.
He suggested and designed a large control panel with many of these features displayed via GUI, it seemed pretty good when I skimmed over it back then, but for the life of me I cannot find the post again…
I would be very careful NOT to immediately try every submission. A mean spirited reply could brick your system.
