There is no battery problem for truck-to-door. The truck charges between deliveries and spare swap-in packs pick up any slack if the duty cycle is too high.
No, not at all. I'm just a regular middle aged driver with perhaps 300k miles under my belt and I've passed numerous fatal accidents on the roadway.
I just sat back and tried to estimate (since of course, I don't have a CB in my car and can't follow traffic details like a trucker) but I'd guess I've driven past at least 5 fatalities -- and that's just fatalities I've noticed (body on stretcher, read about it on the news later, etc)
Only for some types of fossil fuels. Saudi light crude costs very little to extract -- a few dollars a barrel -- whereas shale oil has an extraction cost of around $70-$90.
You're right in that the Saudis will likely never stop extracting. But there are much larger deposits in the Americas that we quite likely will never develop if solar brings down the price of energy.
You do understand that all of those options require someone to pay for the services? I don't know why we're still having a conversation about this. An institution with employees costs money, unless the institution is entirely comprised of volunteers (in which case the volunteers are paying with their time).
It's not wrong. Making something free means paying for it in a transparent fashion.
Bernie Sanders is not talking about changing the institutional structure of college such that it somehow has no cost to provide. He is talking about the government paying that cost on behalf of students.
I agree with free education, by the way. We currently spend our budgets on much less useful things. But let's be honest about what it means and how it works.
Agreed - replication is the key. There are two key perspectives on what architectural purpose a database serves:
1) As a relational query engine first and foremost. Postgres wins handily here, leaving people wondering "why use Mysql."
2) As a reliable replicated datastore, which perhaps happens to be queried via SQL or some rough approximation thereof.
One item you didn't mention is how the replication chain behaves in the event of a node failure. With Postgres, yes, you can promote a slave to master, but last I checked (~2 years ago) promoting a slave to master would break replication to all other slaves, causing a complete loss of redundancy in your entire cluster. I believe this may have been addressed recently; I know folks were working on it.
Going back slightly further in history, Postgres has always lagged far behind Mysql in terms of replication tools and ability. What Postgres has going for it is a far, far superior SQL environment. Which is fantastic; I absolutely prefer it as a developer. But it can be a complete non-starter operationally and architecturally.
"Rent control is a subsidy to renters paid by landlords"
I'd expand on this: Rent control is a subsidy to current residents, paid by future residents. The landlord is merely a conduit across which the wealth transfer flows.
" However, we would have to worry about food supply issues nationally and economic issues in what is already one of the most economically depressed areas of the country."
The impact would be relatively minor. For example, we could simply stop growing rice in the desert and more than recover all water saved by urban use: http://www.kevinroderick.com/rice.html
There's more water lost to evaporation in rice fields than LA uses in its entirety all year long. We could very easily move California rice production to wet areas in the south which don't suffer droughts and which already produce most of our rice: http://en.wikipedia.org/wiki/Rice_production_in_the_United_S...
This might be fine if their compensation plan was formed in 2015.
