openSUSE Tumbleweed is the rolling release, where you may have dependency decisions to make during regular updates. Updates must be done in the terminal.
The more beginner friendly version is openSUSE Leap. That has a longer release cycle, and you use the Discover interface (or yeast, or zypper in the terminal) to update.
I also wonder how closely they can be dated. +/- 100 years is a long time and I would expect that's a smaller interval than provided by their dating methods.
Still, Neanderthal dinner parties are nice to imagine.
I've seen a few ways for chopped onion. Chopped meaning that we want reasonably small consistent size pieces.
Root on, halved through the N & S poles, one half laid flat, vertical N/S cuts, leaving connection to root intact, cuts parallel to table almost to root, latitude cuts moving to the root end. Then a final cleanup chop of the large pieces from the root end.
Same as 1 but no parallel to table cuts. More cleanup chop at the end.
Same as 1 but radial longitudinal cuts instead of vertical.
Same as 2 but radial longitudinal cuts instead of vertical.
Same as 1 but without halving the onion first. Done in the hand.
Same as 4 but without halving the onion first. Done in the hand.
Same as 4 but root off before halving.
Same as 7 but latitude cuts before radial.
Same as 8 but latitude slices laid flat before radial cuts.
Same as 7 but root off after halving.
Same as 8 but root off after halving.
Nana method, higgledy piggledy paring knife action in the hand.
Classical western method is 1. Both 2 and 4 are very common in restaurant settings in my experience. I like method 8. Any other way feels either too fiddly or too sloppy. But I have seen each of these in action.
Here's a fun comparison:
Tennessee vs Mecklenburg Western-Pomerania
They have very similar population density (70/km² vs 65/km²).
Tennessee is roughly 4x the area and population.
There are only 2 inter-city train stops in Tennessee, in Memphis and a small town to it's north, both on the 1x/day service between Chicago and New Orleans. The largest city (and its state capitol) Nashville has no rail service.
The entire state of Tennessee has only 10 inter-city bus stops. Ten! Serving 7M people. The 4th largest city in the state is Chattanooga (181k), and it has no inter-city bus and no rail.
The worst part, from a transportation perspective, is that our low density rural areas in the US are often isolated homesteads. Fully scattered single family farms and ranches, miles from the next family. We don't have as much village centric rural areas as in Europe. So it makes delivering services (transportation, education, health care) to our rural population much harder.
Being on-call at any hour is something to consider. With a large enough organization it can reduce the frequency, but it never goes away.
Also, maintenance is scheduled for critical systems at low demand times. It's another reason to be prepared to work nights.
