I'm not sure of their business model, but my understanding is that AirBnB doesn't set the price of the rentals or pay the home-owners, they take a cut of whatever price the homeowner decides to charge.

As I see it, Uber employs drivers, whereas AirBnB facilitates BnB owners.
They weren't representing HM Government when they made those suggestions. I think the claim didn't make sense either, but it wasn't proposed by any group with the authority to enact it. It wasn't a general election and Vote Leave haven't formed a government or written a Queen's Speech.
I have GTX 970 and how much spare space do we need?

I have to disagree with this premise as it pertains to automobile engines. Automobile engines have improved tremendously in "lifespan" or Time Before OverHaul. In the '70's and '80's it was a challenge to get an engine to last 100,000 miles. They needed frequent oil changes, spark plugs replaced, had other short-life wearable parts (ignition parts), water pumps to replace, fuel pumps to replace, alternators went bad, oil leaks (rope seal packing), etc. In the early '90's some real improvements began to become apparent. Now cars routinely make it past 100,000 mi without replacing any of that stuff, and while producing more power per unit of displacement.
Something that the article does not mention: equality operations are cheaper with hash indexes than btree because less data pages need to be fetched. This is good particularly on columns with a high cardinality.
One gotcha with the Starbucks approach is that it's very dependent on how much the audience for your startup overlaps the audience for Starbucks. This is going to heavily depend on both your startup and your area - asking random people at my local Midwestern coffee shop about a new AP database-as-a-service is not going to go well, but it might at some spots in SF.

One approach I've seen used to counteract that issue is the old "landing page without a product", where you use targeted ads to put your landing page in front of people who might be interested.

There's a second gotcha, common to both approaches: there's a significant leap between "gets excited about the product / signs up for the mailing list" and "actually pays for the thing".
Could this be just a decoy strategy from Apple while they work on something more tangible? AR is not a smaller disc or faster processor, AR does not exist - yet - and may very well never exist due to physical constraints (you can not paint black etc).

I'd first check if those "bridge sites" are really black hat or simply a very labour-intensive and effective way for them to increase their SEO efforts. What's the quality of those sites like?

Also, sometimes sites have a short-lived improvement on Google by using black hat tactics. However, sooner or later Google catches up and penalizes them. So be careful about copying them!
I just changed a refrigerator, stove is basically dead, both 8 years old, Whirlpool brand. My Mom is still using the same appliances from when I was a kid. Nearly every family member I have says the same thing, new stuff lasts about 8 - 10 years and why can't we just get one like Mom's that will last 35+ years. My bosh dishwasher runs like new and is 8 years old.
Do you have any evidence that it isn't true? :) A wealthy family, if you have one, would be an excellent source of money for a startup.

It's sometimes hard to tell which bits are for real, and which bits are the play-acting, but I've long suspected anyway that more people than you'd think are playing startup. Does it matter if it's with somebody else's money rather than their own? I say no... but of course if your story fits the rags-to-riches American Dream then this can help ennoble what would otherwise be a straightforward tale of simple money-grabbing.
so it's practically paper?
Question for the Postgres developers who I know are lurking around here ...

What's the disk usage of hash indexes v.s. regular btrees?

Does it depend on the underlying type or is it a fixed size regardless of the key fields?

How's this compare to the poor man's hash index, i.e. BTREE(HASH(keys...))?

EDIT: I got curious so I ran a test of building btrees vs hash indexes. This is done on 9.6 (not HEAD with the new WAL logging supported hash indexes). Looks like the sweet spot is when the key size is around 20 bytes. After that the fixed size of the hash index gives it a win (on space usage) v.s. the btree which would have to repeatedly store the key values.

key_size int,
btree_size bigint,
hash_size bigint

James Dyson was pro-Brexit anyway, so that might affect whether you consider Dyson (the business) to be a meaningful data point.
Interesting. And on the flip side, you have the law of Jante. Or is it OK to proclaim one's self as super happy? Maybe Jante is more about material success?
The Supreme Court is the only body charged with interpreting the Constitution, and they've been very consistent and clear that for the most part the fourth amendment doesn't apply at the border. 4A protects against unreasonable searches. Searching people entering the country at an international border is entirely reasonable, so 4A doesn't apply.

Obviously there's debate about considering a state road 98 miles inside the country a "border zone," and I don't think border rules should apply there, but at the border is pretty much settled law.

As a society, we have no way to differentiate who we're mad at, and who we're truly afraid of. Rehabilitation options are nonexistent, as most prisons and jails removed them in the 90's. Offenders go to Prison and come out Convicts -- with better training, some more street smarts, complete with access to more drugs, guns, and tools of the trade.

America is not a country of second chances. Look at sites like beenverified and mugshots -- their sole purpose in life is to shame those who have been arrested/convicted and allow employers/landlords to discriminate in ways that really skirts the FDCPA (beenverified isn't a CRA, so, there are no repercussions of reporting inaccurate information, nor are there ways of getting that information changed).

Hell, even AirBnB performs silent background checks on people who are renting homes -- even after presenting them the official copy of my clean (aside from a few speeding tickets and an accident from 1999) FBI background report, they still say that there are 'public records' that they are using and for the 'safety of the AirBnB platform,' they don't want my money.

We have a long way to go until this country can truly start to fix the 'prison' problem, but, it won't start until the country, as a whole, starts taking a different view of rehabilitation, corrections, and punishment.
You are 100% right, if you're in a state with a progressive state income tax your effective rate can go up pretty quickly. I am spoiled to live in a state with a ~3.2% flat income tax.
I've heard it said that much of it goes back to the Calvinists roots of American culture. The idea that there are good people and bad people, that you are one or the other.

Bad people deserve to go to prison, and therefore people in prison are all bad people. Why should any mercy by shown to bad people? Why should good people have to pay to help bad people? That sounds immoral.

By the same set of rules, good people deserve to be rich, so therefore rich people must be good.

It may not be correct, but it sure does seem to accurately describe how American culture works.

Traditional taxi companies are now increasingly employing 3rd-party apps which function much like Uber's. In many US cities, the "Curb" app will hail you a regular taxi cab and allow you to pay for the whole thing through the app (including tip, even if you just happen to hail the cab without opening the app).

Uber's long-game, and the reason they've been funded so handsomely, is the autonomous taxi plan.

Its a pity that taxi companies were so slow to adapt to Uber by providing convenient ways to summon and pay for a cab. All that people really want is to get from point A to point B without a hassle.

The only way Brexit involves people being forced to leave where they live is if the EU forces it to happen. The UK has already said many times it wants to take that possibility off the table as soon as possible.
>infamous for it's Hitler in the bunker clip.

Interesting side-node about 'infamous'. Just because a movie depicts a terrible event or subject (Hitler in this case), it doesn't mean the move itself is 'infamous'. The movie (i.e. the artists) didn't do a terrible deed (e.g. completely misrepresent Hitler as innocent), so in this case the movie is simply "famous for it's Hitler in the bunker clip".

I am an Indian who have lived for a while in NZ. Please do not chug on this Kool-Aid that NZ is not corrupt. Part of the reason why real estate in Auckland is overpriced is because the government deliberately does not formulate a legislation that forbids non-residents from buying up property. Please petition for this reasonable legislation. Who does the current policy enrich?

It is your country. I think you should fight for it. Corruption comes in all shapes and sizes, and underhanded disenfranchisement is the insidious form it takes in NZ.
I'm not sure what you're talking about. AR already exists:

https://www.microsoft.com/microsoft-hololens/en-us

It isn't necessarily useful but it exists.

As for whether this is a decoy strategy... Apple aren't even promoting this so it's not a strategy on their part; it's just information pieced together from hirings, anecdotes and guesses.
One of the features Apple is exploring is the ability to take a picture and then change
the depth of the photograph or the depth of specific objects in the picture later; another
would isolate an object in the image, such as a person's head, and allow it to be tilted
180 degrees. A different feature in development would use augmented reality to place
virtual effects and objects on a person, much the way Snapchat works.

Oh come on.

I'm completely unimpressed to hear Apple working on AR if that's the best they can do.

It's a fabulously hard problem that no one has come close to solving; and to be fair, if they poured R&D $$$ into it, maybe they could make something out of it...

...but you know, since I can't use a Vive or Occulus on a mac, because of the ancient ass version of opengl they support, and the ridiculous on going split between vulkan and metal, I'm kind of unimpressed by the weight of their technical prowess at this point.

I don't believe it. General consumer AR won't come from Apple.
That's a cop out. If they didn't have the means to deliver on their promises they shouldn't have made the claims.

They took highly populist positions, completely divorced from reality just to win votes, then shrugged their shoulders post-referendum when asked how they would be implemented.

Your evidence is still an anecdote, it just involves a couple more people. Still potentially involves some amount of confirmation bias.

Whatever you may think it is still true that it takes more calories to grow a cow then you get from a cow. No matter what kind of food a cow consumes.

Weather those calories were going to be used by humans or not that land is now used to feed some cows that will feed a few people. Instead we could use that land to grow plants and feed more people then with cows.

Also, AFAIK, that natural environment where cows are fed is mostly created by destroying forests.

> people no longer trust the MSM because they're being told not to by politicians

I'm not sure that's the biggest part of the problem, though maybe it's different in my bubble. In my experience, the MSM destroyed their own credibility by acting as stenographers for political and corporate power, and, in the process, spreading "fake news". And it wasn't the little independent partisan sources, it was literally the WaPo and the NYT that helped the Bush II regime lie us into the Iraq War (14 years ago today!)[0].

It's hard to gain back credibility when you've so comprehensively destroyed it in order to be close to power. And the NYT and WaPo have not even pretended to be interested in doing so.

To your point, I saw or heard an interview with a Ford engineer a while back where he basically said look we know how to make parts that last forever, but they are heavy and expensive. He went on to say people want more affordable cars (cheaper parts) and we need to make cars lighter for fuel efficiency standards (lighter parts), so they set an internal goal of 10 years of longevity for a part, and then try and make the cheapest/lightest part that meets that goal.

Hash indexes have other benefits than just algorithmic complexity too: traversing and updating tree structures requires a lot of pointer chasing, so in cases where your btree index might not fit well in a reasonable level of cache (L3 etc), then this means paging stuff in and out of memory a lot, which can get very expensive very quick.

And also with updates to hash tables (e.g. transactional workloads), they're very quick, versus btree updates require traversing the tree structure.
As an Apple fan, this smells like the Apple car rumours. Moonshot projects to retain talent perhaps?

>>I suspect the root of the problem is our system of education. The primary goal these days seems to be obedience and unquestioning believe in authority.<<

You would think so. But my dad is a varsity Professor with a PhD, my mom has a Masters in English.

They believe literally every cock and bull story they see on Facebook.

You make an interesting point when you state that "The primary goal these days seems to be obedience and unquestioning believe in authority." because for me that is both the problem and, ironically, the very obvious solution.

If there was a trusted (read, authoritative) service that one could use to vet such stories then the problem would go away.

If I was incorporating in Europe today and didn't need SEIS/EIS I'd definitely at least look at Ireland, Germany, Malta and Estonia before automatically picking the UK. The criteria would be something like:

2). Is it easy to open a business bank account there
3). Are investors familiar with that country
4). Is the required paid up share capital on incorporation small
5). Is the process quick (and corporate tax rate & legal compliance burden not too onerous)
