The only food that is unhealthy are those pre-packaged with tons of salt, sugar and fat and have had all it's nutrients removed in the cooking and preserving stages.

If it is full of sugar and fat then it's full of nutrients, not void of them.

It probably should be mentioned (since few seem aware of it) that they also provide their UberX/UberXL* drivers with supplemental commercial insurance.

While at the same time they suspend drivers if they register their cars as commercial vehicles - even though that is what the DMV tells the drivers to do. Also, the insurance only covers when there is a fare in the car, not when they are driving to pick up a fare.

Not just Cuban:

Check out the charts.

If you base it on revenue, it wasn't. Period. But if you base it on the value of SMS and MMS services income in (mostly foreign) markets that it destroyed in the last fiscal year, it destroyed about $9B in revenue for telephone companies. so $18B is worth 2X revenue destroyed, then its valuation makes a lot of sense: it's worth ~$9B/year in *leverage* over these telephone companies. Facebook needs this, if it wants to achieve additional marketshare by growing its available customer base.

These valuations are based on more than "grab as many customers as you can before someone else does, then figure out some way to monetize them", which was the Netscape model, and the model everyone at the time was using before the dot-com collapse. They are based on the value of leverage. This is why so many of these companies are being acquired for vastly more than they could possibly IPO at: they are being acquired for their value as leverage, not on their revenue.

If you've got a $1.25T/year industry by the balls, and all it cost you is $18B, you got a deal.

How exactly does the revenue destruction leverage calculation work as a business model? Blackmail?

"Can you drop Carol and Benji at the mall on your way to pick up the rest of the kids?

But it is on substantially the same route, just like other carpooling. Plus Mom might get gas money, but doesn't turn a profit no matter how many kids get dropped at the mall. No taxi medallion for Mom.

They are sharing a ride in their personal vehicle.

Because they were going that way anyway? No, they are a transportation service for hire. The only reason the companies call it ridesharing is because of the legal loophole big enough to drive a Toyota Prius through.

I agree it's not a problem. But who cares. If the result is important it will be replicated. ...if it's not important then no one will cite it... People will make errors. If they weren't then then were not paying for aggressive enough research.

The problem is opportunity cost. There's usually a big lag between research getting published and being formally replicated - or debunked. Meanwhile, grants are awarded and lots of FTEs get burned to do research based on work that turns out to have been shoddy. All that time and money could have spent on research that actually proved or disproved something. "Aggressive" doesn't really enter into this problem (lack of aggression is a better topic for a discussion on science funding priorities, not design of experiments). Are skiers who take the time to buckle their boots not being aggressive enough?

Stock valuations are based not only on actual assets, but future growth and earnings potential. If I buy company X, it's because I think company X has a good product, business plan, and management and is going to be able to grow faster than inflation and faster than their competitors..

That's a very quaint view, which is definitely not held by the parties which conduct the most trading. Stocks' values are mostly determined by what institutional traders think will happen to the stock's value in the next 3 seconds to 30 days.

While some multi-center studies may receive data with patient identifiers, they will either be rejected or scrubbed of these identifiers prior to being added to the database and being analyzed.

Things like age, sex, geographic location, occupation, genetic information, and medical histories are also patient identifiers. If you scrub those you can't even determine whether the subject should be in the study, let alone score them or put them in subgroups.

The number tied back to a list of data about the patient - not including anything personally identifying.

Now that is specious, considering how little it takes to de-anonymize data and how often it will include genetic info in the future.
