Meditation makes a huge difference for me. I've tried a number of different methods, including using biofeedback devices but the most effective for me has been http://www.headspace.com. People who tend to have difficulty turning off the noise in their heads (such as myself) do well with guided imagery training such as that.
I've seen convincing results from amino acid therapy, but I sit among the skeptics on multi-vitamins. Without some sort of differentiating research for their products, this doesn't seem vastly superior to a recurring amazon purchase.
Just to give a difference of opinion, I don't think that this is necessarily representative of the entire HN community. I for one maintain a FB account almost exclusively for apps like this, so that I can reuse my social graph.
Disclaimer: I've done work in the past with one of the founders on a former iteration of this product.
Agreed if things are going right - but again, for the sake of discussion, one could fathom there being some sort of bug. I don't believe that this could realistically be the case, but I'm just trying to mention all possibilities...
To play devil's advocate, I wonder if it's possible that there is no foul play on either side - if the car had issues displaying accurate data to the driver but logged properly to Tesla, he might have thought he was discontinuing the charge with a fuller battery then he had. Same for the speedometer (a chilling thought) and temperature.
As for the circles in the parking lot - I'd probably do donuts too if I was given free reign over a slick sports car.
Obviously it's far fetched to think that display inaccuracies were really the case, but food for thought.
