if you count all parts, bottom, keyboard, cover, battery its more like 500 to 600.

The attachment mechanism is usually standardized, so you can just switch between brands.

Nowadays a larger factor might be how close the next dealership/repair shop is. Some things are time critical, and when it breaks in this time, then you don't want to drive hours to have it fixed/get a part/ have a mechanic available.

There are some differences between the brands... And you can always be Clarkson and get a Lamborghini, even when it makes no sense ;-)

i am curious: is the performance gap between x86 cpu inference and apple silicon, or, a imho more apples-to-apples comparison, e.g., amd strixpoint halo vs apple silicon?

i would expect the "pure" cpu inference to be behind, but an approach like strix halo/dgx spark to be much closer?

I am fully on your side, but tests are not 100%: False positives and false negatives.

The way out is obviously better tests and not less tests :-)

What one has to keep in mind as well, that even though tractors are really heavy they spread that weight across a large area (using low tire pressures and having massive tires to begin with). So, iirc, the per area impact is even lower then a human. It impacts a lot larger area, though!

Plowing vs tilling is also very much about soil erosion and depends very much of the location you are in.

Compaction is sublinear with weight, make the tractor heavier so it combacts more makes a small difference where the tires are - but you can now pull something bigger (assuming horsepower) and that means less of the field is touched by tires and in turn less compaction. compaction is worse where the tires touch but they touch less.

the above is also why tires are better than tracks in many cases. The tire has more compaction, but when you turn it touches less land and so overall is better than a track.

of course every soil is different. For details of you particular land you need an expert who knows your soil.

you can use git with overleaf, but from practical experience: getting even "mathematically/technically inclined" people to consistently use git takes a lot of time... which one could spend on other more fun things :-)

Not affiliated, but for Germany I'd check https://gh.de ... For technical products you can filter for mostly any relevant detail... At least most German shops are there, and only a few not.

I am always curious why there doesn't seem to be something similar everywhere?

try it with ramalama[1]. worked fine here with a 7840u and a 6900xt.

As payment is very much a "relative" problem, giving everyone else more, means essentially giving train drivers less.

The fiber installing crews around here go street by street and usually do one street section per day/or two.

Germany also does a lot more construction on main roads at night compared to what we see in North America.
