Over four years a number of users from StackOverflow built Tetris using the OTCA Metapixel. To summarise, they built layers of abstraction to move from the Game of Life, to Metapixels, to wires, to logic gates, to a RISC computer. There they developed their own assembly language to write tetris and finally compiled and ran it. In total the world is 2,940,928 x 10,295,296 blocks in size.
Here's an interpreter for that language running Tetris: http://play.starmaninnovations.com/qftasm/#jllHdnBGSP
Perhaps in America, but you can certainly "exist" in virtually any European city without a car. Anecdotally, I have managed to "exist" for the past four years without owning a car. I know how to drive one and possess a driving license, but have chosen not too.

On the otherhand, with Swing all you need to do is add the following line:

PINs as discused are not directly comparable.
VISA is capable of handling 56,000 transactions per second [1] while Bitcoin is capable of handing a measly 2.5 [2]. Bitcoin would need to scale by 224,000% to match VISA, and VISA is one of my different global networks. I don't know how much energy VISA uses but as of today, the bitcoin network is estimated to be using 16TWh [3], that's the same as all of Jordan or Lebanon or 5.2% of the energy consumption of the United Kingdom [4].
Assuming no energy consumption improvements, to scale to VISA levels Bitcoin would need to consume 224,000% more energy. That's 35,840TWh, which is nearly twice as much energy as the entire planet uses (21,776TWh)!!!
So, if Bitcoin is able to become 90% more efficient, it would only require as much energy as nearly two European Unions. If Bitcoin is able to become 99% more efficient, it would only require as much energy more energy than the entire United Kingdom. If Bitcoin is able to become 99.9% more efficient, it would only require as much energy as Qatar. I can keep going but I won't. I might have made a mistake and been a factor out, but even then it doesn't even matter, that's how ridiculous the numbers are.
I don't know about you but I find it rather unlikely that Bitcoin will every be a viable replacement for the world banking system. Maybe in a universe where Nuclear fusion is easy and ASICs never wear out, and the cost of cooling them is free but unfortunately for Bitcoin we don't live in that universe.
Bitcoin and crypocurrancys are horrible inventions if you care about the planet, if you think a massive decentralised network where value is created from ever increasing difficulty proof of work could be more efficient than VISA you are frankly deluded. Granted, this is someone who does not own any Bitcoins, so maybe I just haven't drunk the kool aid.

Google tells me that the average person weighs 80.7kg, let's conservatively round up to 100kg to take into account clothes, and luggage (It's probably higher). From this we can estimate that the PIA flight had an extra 700kg (It's probably closer to 1 tonne) of weight on board, and extra 700kg that wasn't properly secured or distributed.
Depending on the plane, the effects could range from using up more fuel (planes carry extra fuel for emergencies and so they can circle their destination while they wait to land, it would eat into this reserve making flight incidents more deadly), to failing to take off the runway; The pilot wasn't informed until he was in the air.
While the plane in question is certainly larger and more powerful than the majority of the links I provided, the fact of the matter is an overloaded bus or train may refuse to move if overloaded, a plane can fall from the sky killing people both on-board and on the ground. Planes fail deadly.
You now have 7 extra, fragile humans standing in the aisle who have nowhere to belt down in case of emergency. If the plane crashes, needs to make an emergency landing, or even encounters incredibly rough turbulence they could be thrown around the cabin hurting both themselves and others.
As for a 1 to 10 scale of transgression, it's hard to place because of the nature of such a simplistic scale. Assuming your scale is confined to aeronautics (lest we invoke Godwin's Law) what counts as a 1, and what counts as a 10? If your 1 to 10 scale is truly inclusive of every possible aeronautical incident then 1 has to be a passenger with a typo on their ticket, and 10 has to be 911. I don't know about you, but I have no idea where to place this overloading incident on such a scale.

Arguably it is a bug that users should know about ;) Pedantry aside, I seriously hope it's a software bug, and not an intentional wiretap bug.
I'm not so sure. Hashtags are everwhere both physical and digital, companies want to to start tweeting about their event/product/etc. As for a direct connection, how often have you see a tweet embedded in a news article, or displayed on live TV?
