Why does San Francisco police guard the Apple Store?

Apple doesn’t get preferential treatment. They pay off-duty police officers to guard their stores during high risk times. Just having a police officer there is a huge deterrent to crime, even more so than a security guard does. So during high risk times and high risk areas, they will pay the police to be there. They’re basically private contractors although Apple does this with the full knowledge and support of the local PD. The local PD doesn’t pay anything for it.

How many Silicon Valley startups succeed? Is it true that a <$10MM exit is considered a failure?

Let’s say you start a company. You build the company up and you sell it for $10M five years later.

And let’s say your friend starts another company. And your friend builds it up and sells the company for $100M seven years later.

Who was successful?

Most people would say your friend because of the larger exit.

Let’s add some more data.

In your case, you bootstrapped the company, so you still own 80% of it. You end up with $8M before taxes.

Your friend raised $100M, and he owned 6% of the company. So he made $100M-$100M or $0.

Ask yourself who was the bigger success? You or your friend?

Is it possible to become Billionaire in early 20s?

In theory, yes….but in reality – you can’t do it at any age unless you already have some tens of millions or a crazy startup or business idea (which should interfere with the current market conditions). For example, Mark Zuckerberg’s Facebook would not be successful if there had already been another social media platform with 1 billion users. He had the luck to catch the trend – the social media was still at its incipient phase at that time.

So, considering the fact that there are over 1800 billionaires for over 7 billion people of the world, then the probability of someone to become a billionaire is just invisible. In the early 20? Even more crazy. The probability of becoming the US President is much higher (according to statistics).

Meet the youngest billionaires:

Evan Spiegel: 25

The Snapchat CEO is the youngest billionaires of the world.

John Collison: 26

John runs the Stripe, an online payment system.

Bobby Murphy: 26

Bobby is the CTO of Snapchat, and yes, you heard it right – Snapchat made two billionaires who appear to be among the youngest in the world. The picture shows Bobby with Evan.

What happens in a book tour?

Book tours are usually pretty grueling for the author. And, I would never go on one where I had to pay the travel expenses. Advances are not supposed to go to promoting your book, and no reasonable publisher would expect this. Advances are what you are supposed to live on while writing the damn book.

Depending on how it is organized it can go like this.

Depending on the size of the city, there will be no less than two and no more than six bookstore signings organized.

There may also be appearances on local media, usually on “breakfast shows,” which are generally hurting for content. These are usually pre-recorded and often happen at 5 AM.

Then it is on to the next city, usually getting into a hotel at 10 PM to midnight, to do it all the next day.

Depending on how much money the publisher is pouring into the tour, the author may be expected to drive himself to these things, may be sent on planes, or may be given a tour bus and a driver. The last is the best, because there is a bedroom in those things, and a bath and shower.

They are never fun. They are generally exhausting. And the author is expected to pretend they are having a good time.

  • Al-Azhar Mosque in Cairo is as well another mosque I had a chance to visit in Egypt.
  • Florence Cathedral located in Tuscany, Italy. It is one of the most beautiful churches I’ve ever been to.
  • St. Peter’s Basilica in Vatican.
  • La Sagrada Familia – a church located in Barcelona, Spain.
  • The Hanging Church in Cairo, Egypt.
  • Mezquita in Cordoba, Spain, a mosque-cathedral from the period of the Moorish presence on the Iberian peninsula.

What are the tallest buildings in the world?

The tallest building in the world is until today the Burj Khalifa, but not for long… Did anyone know that the Royal clock tower Mekkah is also one of the largest? I am traveling a lot and it is so hard to imagine how high a building really is. It makes more sense if you can visualise a building next to a building you have seen several times in real life. There is an outdated website but still funny to use where you can put them together en visualise it perfectly.

What will happen if people are able to make buildings as high as 10 km?

We’d all suffocate due to asphyxia.

Also we’d end up with a sore neck from looking up towards the top of it.

Based on answers by writers such as Robert Frost, as well as plenty of reading about aircraft safety, it’s clear that the maximum altitude where we can comfortably and safely breathe without any extra air source is 10,000 feet, or roughly 3 kilometres.

Building up to 10 kilometres would also require a lot of work with regard to structural design, mainly due to the fact that the earth spins faster towards the outside of its turning radius than it does to the inside of said radius.

This naturally means that there is more resistance to the air pushing against the walls of the tower.

The World Trade Centre, for example, was designed to bend and sway several centimetres in a wind storm.

The Burj Khalifa, the tallest building in the world at 830 metres, was designed with its radical styling specifically to combat wind resistance.

The Burj Khalifa among the skyscrapers of Dubai.

And then there are the materials needed to actually build the building.

Can I say exactly what they should be? No, I’m neither qualified nor experienced enough to talk about these. There are better people to go to for that. I will recommend something that doesn’t have holes in it though, for obvious reasons.

And finally: pressurisation.

You’re suggesting that we build buildings as tall as 33,000 feet, correct? This also poses a massive hazard for air traffic, but we’ll get to that in a bit.

Speaking of air traffic: the inside of the buildings would need to be pressurised to around 8,000 feet or lower so that we can breathe, the same as a conventional aircraft

This means large amounts of emphasis on window and door design more than anything, so that this pressurised air doesn’t escape. UV protection so that people don’t immediately get burned by the sun is a necessity.

As Muhammad Irfan said in his comment, air conditioning would not be a necessity in this building, since the average air temperature at 10km is about -50°C. All that’s necessary are some good heat exchangers to move that cold air around the building.

Here’s the link to the full comment.[1]

Sorry it took me so long to get this update out Muhammad. I’ll be honest: it slipped my mind.

Also doors between levels and the outside would need an air-lock system so that little to no air escapes. Or at least constant and filtered air pumps so air can be pumped in from outside.

Alongside this, as Dwi Aji Kurniawan mentioned in the comments, you’d need a high-speed lift system (or several high-speed lift systems) to get around the building, probably travelling at around 60 km/h, in order to get from the top to the bottom in less than a lifetime.

Speed control for the lifts would also be critical, as I don’t think it would be altogether comfortable to go from 0–60–0 kilometres per hour in the space of three to four metres. I’d imagine a few people would end up with broken legs if that was the case, and lawsuits aren’t exactly wanted in any business, much less the tourism business.

So that’s the main things that I can think of which would need to be done to build the thing, now let’s look at the effects of a building at such a height.

Air travel

Aircraft require a drift-down altitude where they can fly to below 10,000 feet in the event of a cabin depressurisation or something similar, and they can’t exactly fly through a building can they?

Imagine that your are skidding a car on ice at 120 km/h (around 75mph for our American cousins) and you see a telegraph pole. You’ll struggle to get out of the way to avoid hitting the thing, and as such you can kiss your car and life goodbye.

This means that air travel over this building is a no-go, pilots can’t fly above it safely. And I have a feeling that would be slightly detrimental to your economy if it is built on tourism from the air.

Window cleaning

Sounds random, and it is. The only issue I can think of is the amount of specialist training, bespoke safety equipment, bespoke cleaning equipment and bespoke techniques required to clean them, coupled with the sheer length of time required to clean them from such a height, would cost a small fortune.

While it would be absolutely awesome to build a building as high as an aircraft, at the moment with current regulations and building techniques it wouldn’t be safe or economically viable to do so. Let’s just stick with our sub-1,000 floor towers instead.
