Here's my sealion of a question. What parts of climate change research are actually backed up by the scientific method (experiments with falsifiable hypotheses and all that) and what parts are more akin to natural history or something else? To clarify, I believe humans caused the problem (it appears that stating this makes people like you more, which is weird, but ok) but I cringe every time I hear the word science attached to the debate. Is it like a social science? I think someone told me that we know for sure that greenhouse gas emissions cause ozone depletion but I can't remember anymore. What is the actual hard science here?
Why doesn't a bike save you a lot of money on fuel? Keeping a car on the road is expensive, you can save on insurance too. Also you can take the bus. I know, it's a pain.
If you can simulate matter, certainly you can simulate a brain. Qualia appear not to derive from pixie dust but accumulated experience in the world. You might need to train a brain for a long time to develop qualia. You might not be able to copy qualia from one brain to another. I think these are the main objections, but I'm not sure.
Personally, I'm not convinced that simulating matter is feasible, never mind a living organism, never mind an intelligent living organism, which is what the brain is, when you account for all of it.
We know how far away Andromeda is. We know how to build a spaceship. Therefore, it is possible to go to Andromeda. Is it though? What if the Earth doesn't have enough resources? How big is your brain simulator allowed to be?
It's actually reasonable. Step 1, translate key push. Step 2, broadcast key message. What you're missing is that there's an alternate Step 1, translate joystick hat push (or mouse drag, or whatever). So Step 2 should be broadcast generic up/down/left/right input message. Step 3, translate message into movement. But what you're missing is that dependent on context, there's going to be other things besides movement that those keys do. Step 4, pan the map with N/S/E/W. Again here, you have the flexibility to work with a rotated map. Your code was probably overdesigned for the use case, but I've seen your solution many times, in books and in real life.
However, I've also solved this problem by passing around polar coordinates, it's elegant and very flexible but you have to munge some data at the beginning. You can also pass around a simple vector [{-1, 0, 1}, {-1, 0, 1}], which is basically what you describe.
On reflection, I concede that AirBnB is largely landlords renting their space or tenants subletting for substantial profit without their landlord's permission. However, I think subletting is fine, as long as you aren't making a substantial profit without your landlord's permission. I've sublet many times with my landlord's permission, it's regulated by tenancy laws, etc.
Japan > England >> USA. Just being able to take the TGV from London to Paris is mindblowing.
I define great as it being generally possible to get where I want to go on the train (this is the most important factor) and then as a bonus it's usually competitive with driving, busing, flying, cycling, or walking in terms of comfort, cost, and convenience.
I think population density is a factor. China and the US have the same area, but China has 4x the population. Consider also England and Japan, densely populated islands with great train service.
When you take a roommate, aren't you sharing the cost of rent? Sharing can mean mutual contribution as much as it means mutual partaking. Also, what? Amazon is not a retailer? They have giant warehouses, they ship physical product with Amazon logos on the boxes, and they accept returns. They allow for 3rd party vendors, but they are still very much their own retailer. eBay perhaps, but not Amazon.
Is a statement of disbelief a belief? I believe that all beliefs are false, except this one? I disbelieve all beliefs, except this disbelief? I disbelieve everything except I believe in the goodness of science? I disbelieve all hypotheses except for falsifiable ones with empirical evidence? I'm not clever enough for this.
This was a neat summary. I'd add that often, you can use a length of string to measure something, without actually needing to know the numerical length. But then from that perspective, a tape measure is just ~2000 pieces of string neatly rolled up.
I think programs written in dynamic languages are generally harder to optimize because they're more likely to take advantage of complex features. Since these languages often compile to C, you can obviously write the same program in C, but you aren't as likely to.
Also consider that fixed point optimization algorithms can only ever approach the optimal solution. Languages that are closer to the hardware generally have simpler (tighter) optimization constraints, and compilers for them will generally get closer to the optimal solution.
This was actually a really entertaining telling of a boring old story about capitalist competition. Act I: We tried A, then we outgrew it. Someone said B was better. Act II: We tried B, then we outgrew it. Act III: By this time A had caught up to our needs, so we went back to A. End Credits
