My wife writes documentation full time for open source software (Red Hat), she was making enough to live off it.

Are you assuming SRV-IOV passthrough (which has its own performance profile) ? Because normal virt -definitely- hits a context switch when it goes from unikernels virtual NIC to real NIC, if not twice.

Why is it essential to have this in app ? Who makes these rules ?

No one said this is a rule but you.

Why? Because of the UX. It completely breaks the creative workflow if you have to save two [or several] versions of an image and switch to another app to compose them together to see an effect applied locally. And then go back and repeat, if the strength is not to your liking.

Besides, Gimp doesn't support floating point image editing, so there is a also data loss involved if you use this app for compositing your RAW samples. Krita & Natron seem the only alternatives on Linux unless I miss something. On OSX, you could use Krita, DaVinci Resolve, Fusion, or Natron. Or pay for Photoshop. In any case, switching apps sucks. :]

DT's authors understood this and added support for masks and module instancing. Plus a ton of blend modes. That's what sets DT apart from the competition when it comes to 'how' you work. As for the 'what': there is very little that the toolset of DT leaves to be desired. Even for professionals. :)

Securelevel in linux has never had a good time.. its also not working so well with kexec at the moment, I think its fix in the 4.x series though.

I've hunted and killed feral cats on properties before, good luck doing any kind of rehoming with a feral cat. They are a lost cause.

You don't 'rehome' a feral cat. You do TNR. Safe, humane, and effective. <http://www.neighborhoodcats.org/HOW_TO_WHAT_IS_TNR>

The arguments in that article don't seem to ring true. It's claiming that simple trap-and-remove just has other cats move into the area and that if you don't catch all of them, the breeding pairs bring population back to the same level. But with TNR, the population is never reduced, since you put them back; you have the same problem with breeders if you don't catch them all; and when the neutered cats start dying out, they'll be replaced by the same neighbours anyway.

Neutered cats compete for resources that otherwise breeding ones would access.

So you have a full competing population, otherwise there'd be spare for the breeding cats. Then when the neutered ones die, existing breeders fill in the gaps, or, as the article says, neighbours come in.

mmmh... yes and no. Neutered male cats are bottom feeders in the cat societies. They will be attacked and easily displaced from the best areas by the other cats.

Maybe is diferent for neutered females. Females stay in the same territory with her mothers often, they only move when are in heat and there is not any appropiate male at sight.
