That's a lot of pills, even at 1,000 IU per.
Also, as a side note, I would be happy to pay a subscription fee, just perhaps not $499/year, for "advanced hobby use". Autodesk could look more into separating hobbyists from businesses, I'm sure it's possible.
The problem is that after OnShape went full commercial, this is the only relatively inexpensive option with history-based parametric modeling.
After college a bunch of lightweight kids from high school would get together and play football. Two straight meetings ending in concussions ended that. We were virtually all less than 150lb.
Their models actually do a decent job of replicating true tennis strategy, and as they pointed out, even account for the quirks like the left handedness of Nadal.
However, it's still a bit unrealistic due to the lack of full data.
There's 3 things that make a tennis shot what it is: placement (covered in the video), pace (speed of ball), and spin (rpm and direction of spin). In this method, they only use placement. Probably because pace and spin data don't exist at this scale.
But there's a big difference between a slice, flat, and top spin shot to the same placement on the court, and it directly affects the return shot. For example, it's a very common and 'safe' play to return a slice with a slice
Would like to see the full extension one day
And yes, ethereum has more potential for problems, it's a much more complicated system than bitcoin. Their current goals are proof of stake (getting away from energy wasting mining) and scalability. Bitcoin is great for what it's great for, being digital gold, but it's pretty far from replacing Visa, ethereum actually has a shot at that.
As the paper states, the biggest problem is with the transition.
The paper also argues that standard time aligns more naturally with our circadian rhythm... but doesn't bother to compare that with the psychological benefit we get from hanging out with friends in daylight after work in the summer, or the psychological benefit of it not being dark when you go home and have dinner with your family.
I totally get that people who wake up early in the winter prefer standard time... but it really seems that for the population as a whole, permanent DST is the better option. And implementing it is so easy: once we're already in DST in the summer... you just never "fall back" to standard in the fall.
