Another common low-tech scam in tipped restaurants involves the 'extra' copy of the receipt. The merchant copy is what you typically fill out with the tip, total, and signature. But if you leave the customer copy, an unscrupulous server can take that, fill it out with a larger tip, and file that one instead of the original.

So make sure to always take the extra receipts with you!

Changing DST would have a much smaller financial impact on businesses and the government than changing open-close hours. Think of all of the menus, window signs, painted signs, business cards, letterhead, and all sorts of other branded merchandise that have to be updated for each business that changes their hours, not to mention the time it would take to update the websites, social media sites, email signatures, etc for online presences. And add to that the huge price hikes for all the companies that do that sort of work as a response to the huge increase in demand for their services. And this doesn't even touch on the second-order financial impacts (like costs of updating existing/potential customers of the changes, updating any time-dependent internal processes, etc)

By comparison, the financial impact of making DST permanent would be far smaller as the mechanism for moving time forward/back is already there.

The paper does not take libration into account, but the good news is that the math here also doesn't require a huge anchor point on the moon like the earth-based space elevator as all of the tension is accounted for by gravitation. But you're right, roughly seven degrees of bend due to libration (both latitude and longitude) would present a big "last mile" problem. Do I hear another paper getting written?

I do something similar to what your looking for with a combination of Synergy (http://synergy-project.org/), which uses your network to send the keyboard/mouse inputs to the correct computer based on your mouse position), and multiple inputs on my monitors. In other words: PC1 would be your base computer, and would have the keyboard/mouse you want to use with everything attached. PC1 would be attached to the primary port of both monitors (HDMI, for instance) PC2 would also have a keyboard/mouse, but they wouldn't be used. It would be hooked up to the secondary port of both monitors (maybe displayport) DOCK1 will obviously have the laptops built-in keyboard/mouse, but that wouldn't be used. It would be hooked up to the third port of both monitors (maybe DVI or RGB) In this setup, you'll need to manually change the monitor inputs, and synergy will direct the keyboard/mouse to the correct places. As far as I know, your only other option would be the matrix KVM (as mentioned above a few times)

NASA didn't design the LEM, Northrop Grumman did. Spacecraft are designed by aerospace companies (like Northrop-Grumman, Boeing, Rockwell, and now SpaceX), and then NASA picks the design they like best. The best engineers are typically at the private companies because the pay is better than at government run NASA.

Well, the first space shuttle, the Enterprise, never went to space. It's easy to have a successful first flight when you have the resources to build a full size scale model to 'test' with. And they weren't coming hot off Apollo; the space shuttle was about a decade later.

They made it needlessly complex. This is why they have had, and continue to have, so many problems. The designers promised several launches each month and a payload cost in $50-$100 per pound range.

The scientific community at the time said much the same things about the shuttle design that they currently say about the ISS; that it's too much money for too little return. Some even go so far as to suggest these overly-complex plans, pushed on the unsupportive science community are essentially aerospace company welfare.
