It's all hard work. The primitives of containerization are in the kernel, but executing and managing them, especially securely, takes a fair amount of trial and error to do it right.
Why is so hard to read an article from someone that is developing containers?
Quote: "Again, containers were not a top level design, they are something we build from Linux primitives. Zones, Jails, and VMs are designed as top level isolation."
Of course it's difficult to compare if they feel maybe a bit less heavy for me than for English speakers, but as a German capital letters do indeed feel heavy for me, as well.
I can identify with that feeling! I'm going to start conducting some experiments, see where it goes. I developed a new task-labeling system and it's been really helpful...intuitively it seems like taking on scheduling next would be a good idea. Vague, intuitive, but good. :-)
If you are looking for a MacBook Air replacement, check out the Dell XPS 13 or ThinkPad x2xx series.
The Dell in particular has very impressive build quality.
If you want a MBP, the ThinkPad x1 Carbon or T4xxs series (note the s, for the slimmer version) are still the best replacements IMHO.
The file selection/multi picker example at least can work with the fzf package alone. There are a bunch of files in shell/ from the tarball that enable a little magic like interactive history support and the inline picker. On Debian they're also installed in /usr/share/doc/fzf/examples/ for sourcing in your .${shell}rc.
No idea about out-of-the-box support for any of the other completions from maddyboo's post :/.
