The Black Hole......

. This is what has been done in this case, combining a large amount of images from the footage having roughly the same content.

What impressed me here is that, for a number of the images you have stationary things (the spacecraft) and moving things (the humans). Previous applications I have seen have tended to focus on one thing (say a planet) that isn't changing from exposure to exposure even if its moving in the frame.



Isn't technology wonderful 🙂
 
Zung, somebody here recently wrote that "they know" people in Suisse live well. My observation, visiting there several times, is that most people live in apartments, don't have their own clothes washer/dryer, don't have air conditioning, etc. with regard to "modern conveniences of home", and pay high taxes.

Would you mind giving us your thoughts about all that? Thanks!

I've got family in LA and San Jose I visit regularly, so I'm familiar with both lifestyles, here and in the US. Some bullet points:
  • Politics: Switzerland is a federal government, the president serves only 1 year, so nobody knows who he or she is, except when something special shows up, like this one who had his picture taken while sitting on a sidewalk and tweaking his speech at the UN in NYC. The guy in front is not his bodyguard, he has none.
    An externally hosted image should be here but it was not working when we last tested it.
  • Wealth: Switzerland has the second highest GDP per capita in the world, at CHF 77,943 or roughly USD 80K, Contrary to popular belief, the banking industries is only about 10% of the GDP.
  • Income: from about 40K/y for a cashier at a supermarket to 10+ Mio for a CEO of a large company. The median is about 6K/month. Income tax is about 40%; beware of what you see on the Web: I used to pay more than what is shown here.
  • Real estate: Switzerland is a small country, with 8.5 Mio people, and Geneva is a tiny little state with an area of 15.93 sq km (6.2 sq mi), packing about 1/2 Mio souls, depending on how and when you count (much more during working hours). So the real estate situation is similar to that of Hong Kong or NYC: outrageous! Plus, if you want to own a house or an apartment, you'll need to pay 20% up front, cash, and with a mid-fi house at about 2 Mio. you do need a fat wallet! So most of us live in rentals, and that's alright: I have a 3 bedroom apartment I pay 1.7K/month, but the current rate is more like 2x that. I used to say for an upper-middle class salary, you can afford either a house, or travelling, but not both.
  • Appliances: most flats have a common laundry room free of charge, so an in-apartment washer is not something you would crave for; I have one but I rarely use it. Newer apartments come with a dishwasher, which I consider mandatory, but hey, it's only $500 and an easy retrofit if you don't have it. Air conditioning is becoming a real problem with the global warming: Switzerland used to have a mild continental climate, and it used to be OK without it, but now it is NOT. To be continued.
  • Criminality: low to nonexistent: once I heard some noise outside, I looked out my window, and saw 2 cops (mildly) roughing up someone; they kind of sensed me staring, so they looked up, felt they owe me an explanation, and showed me a plastic bag, saying: "He's a dealer!"; so I said: "Good job!"; that was the only time. We do have burglars, they broke into my apartment once while we were scuba diving in the Maldives, but that was the doing of what is known as "The Gang of Lyon (France)": imported, not domestic. Mass shooting is unheard of, even though Switzerland is the heaviest armed country in the world: check this out, and part 2 is even better.
You know what? We're happy. 🙂

The story told to us outside CH is that, when you end your national service you are given your hand gun to keep (just in case), just no ammo to go in it. Hence the 'nearly 100%'

Just checked with my gun freak: yes, you can keep whatever firearm(s) you were given, but not for free: it's $100 for a rifle, and $30 for a handgun. And you have to buy the bullets too, but that's nearly open market. And I also confirm the son has more firearms than I have fingers, so I can't give scottjoplin an exact count.
 
My bet would be Israel is the most heavily armed country, as both men and women serve and keep weapons at home. What I found interesting is an Uzi sub machine gun is considered a women's weapon.

As it does not seem to show up on lists of guns per capita, I suspect the actual % is a secret, or they don't count as the state owns the weapons.

Yes, Zung, how (well) are you living today? When I was there in 1986, you were doing just fine. Are you living alone now? Of course, the Swiss have a higher standard of living than most have in the USA. The roads are cleaner, along with everything else, but I hear that you cannot flush your toilets after 10PM, is that so? '-)

John, since you came last time, I branched out into the computer field, working for a large US company, which lifted my income into the mid-fi zone. Now I'm retired with an OK-ish sort of pension. Large cut in my revenue, but still nothing to complain about.

I'm still married to Emmanuelle, the brunette you met once in Berkeley and once in Geneva. After 30+ years of marriage, we've diverged enough to consider a divorce; no drama, except she wants me out of MY apartment... Ladies. 🙂

2 kids, twins, they're OK, but they don't get along at all, between them. I heard it's normal for twins.

And yes, in Switzerland, cleanliness is something I like, everything is well kept and smooth running. Not perfect, but OK. What I don't like is at a local level, city/county/state, the government is run by incompetents: nice guys/gals, but totally unqualified for their jobs.

And no, we're allowed to flush our toilets anytime we please in Switzerland Free Country. Most modern flats are designed to have toilets from different apartments adjacent to each other and far away from the living quarters. Actually, the only time I experienced restriction was in Berkeley, 1978, during the drought, where signs were posted everywhere that said: "Everytime you flush, you waste a gallon: think!"
