I bet this tunnel boring idea was inspired by the lack of an economical path for hyperloop to get to downtown LA. The hyperloop concept took a lot of heat for that.

Once you've done that, you can drag the whole selection into another window or a new window too.
Competitors just dump their flight-tested hardware in the ocean, when it is truly a goldmine of test data.
SpaceX is able to do all this testing with a free ride on paying launches. There's no risk to the primary mission, and they get to develop their capability.
There will be failures with reflown hardware for sure. I'm interested to know how well a failed engine can be isolated in flight so not to affect the others.
I would think in theory they could use the camera alone to detect an approaching vehicle, and take some remedial action.
However, a couple of years ago, I noticed that I can actually drink caffeine without getting any withdrawal problems at all, making me think it was all in my head...
Ah, my favorite theorem, The Hairy Ball Theorem!
This is the big question to me... when is the right time to go? If we wait 50 years, wouldn't the technological progress make such an endeavor cheaper, safer?
And the counterpoint is, well... it's been 50 years since apollo and still we don't have the ability to get to mars, so if there's nothing driving the technology then it doesn't just magically happen, and there's nothing to say that it will magically happen in another fifty years either.
To me, it's not the natural extinction events that are driving this, but the thinking that there is a short window of perhaps 200 years between technological enlightenment (particularly in nuclear and biological engineering) where the risk of self-annihilition is considerably increased, and the only way to decrease it is to add the redundancy.
To be sure, we will not achieve redundancy during the first decades or even perhaps centuries of this colonization. I think that terraforming needs to happen first
So, the advantage is that you build a completely separate civilization that is relatively immune to all these problems.
I would imagine that, after reaching the point of self-support, Mars inhabitants would focus more on securing their own existence, such as building underground.
If your neighbor was already at the end of their charge cycle, then they will be drawing relatively little, and you'll get the full current.
I never understood the pressure he was under to open new accounts. Not new customers, just new accounts for existing customers. For example, a new savings account to split your savings up into long term, vacation, college fund, home improvement.
As a banker he was supposed to open 40 new accounts a week, bare minimum.
One theory I had is that if you spread your money around like this, you're more likely to go below the minimums required, so therefore more likely to incur fees.
Be aware if you are buying a car from tesla, that you are at their mercy in terms of parts. There are no third party parts available, and tesla is using all the parts for new cars.
I do remember at some point having access to a language with less restrictions on variable naming, and thinking, "wow, that's so amazing"
I think this is the right choice, but my code reviewer didn't. But he didn't click on the quora link.
Why is okay for mathemeticians to abbreviate things but programmers? Is it because they deal in more abstract entities where the name is irrelevant?
'Set a timer for 20 minutes' is faster for me than using the clock app.
'Navigate to the nearest gas station' is faster.
Setting reminders is usually faster with Siri. Especially geofences ones.
Finding pictures in a location is much easier with Siri.. "Find pictures at Lake Tahoe"
The main problem is that you have to remember what you can do.
They don't do it because they don't need the data. Governments do, for when they need to do search and rescue. So, governments should make it a requirement.
For a manager making a decision in an airline whether or not to use this service, he would have to justify the cost to the airline. If none of his competitors are using it, then he's just got an unnecessary cost which the airline has to eat or pass on the cost to the customer.
The way around this is to make it a requirement for all airlines. Then everybody has to eat the cost.
You may not be aware but there is an effort in the United States to move aircraft from primarily radar-based Air Traffic Control to GPS-based. This requires all planes to be equipped with additional equipment to transmit their location, and there is a mechanism to transmit via satellite. It's just not a requirement.
