    To verify this, go to Coronavirus Update (Live)[^] and sort on the rightmost column ("Tests/1M pop") to show which countries have the highest test frequencies. Be careful not to point out countries that are not as high as their leaders proclaim that they are. That is defined as 'politics', which is is inappropriate in the lounge.

      https://www.cnet.com/news/heres-how-youll-get-apple-and-googles-new-contact-tracing-app-for-your-phone/ Will you install it? Why, or why not? Personally, even if there are privacy issues I think it is worth it for health safety. However, I think we need more than this. This is a reactive solution not proactive. We need something to let us avoid exposure, not just let us know when we've been exposed. Thoughts?

      No, for obvious reasons.

      The only things necessary for health safety is the NHS (IMO, any country that doesn't have something like the NHS is doing bad by its people), and an organisation like the WHO.

      True.  We need the NHS and the WHO. And not "tools" that will end up being used as spyware and/or hacked.

        The figures are provided by health professionals, not leaders; and mocking leaders (no matter their politics) is appropriate everywhere outside of Russia, the Middle East, and Asia -- where it may technically still be appropriate, but it's probably a bad idea.

          If you get sick from covid-19 yourself, you should pick up your phone and call everyone that you have been at an unsafe distance from the last week or two, and suggest that they are being tested. That is all the app does. You can do it manually.

            True, but at least here in Norway, the plan is to raise the flag only if you have been within two meters of an infected person for fifteen minutes or more. Those you pass on the street or at the grocery store or wherever, for a brief moment, will not be included. That of course makes the app completely useless for its stated purpose. Of course it makes it possible to realize the system: It probably reduces the amount of data, and processing, by two to three orders of magnitude, maybe even more. I know who I have been within 2 meters of for 15 minutes or more, without needing an app for it; they are very few. I got the impression that the great majority of alternative apps (maybe all) will require that you are within 2 m / 6 ft for some period of time before filing it as possible infection encounter. Walking past 200 people on the street, being within 1 m for a small fraction of a second, is ignored. If it was not, you would have a line of a thousand people waiting in line for testing. If they keep the 2 m distance, the line would be two kilometers long :-) Maybe the Norwegian limit of 15 min is extremely high, though. If anyone can tell the limit in other countries / apps, I'd be curious.

              Not necessarily ignored by the virus. You might get infected at such conditions too.

                  Exactly. So I consider the app next to worthless. In any case: None of these apps do anything to stop the virus. They just report later (up to two weeks) that you may have been close to someone (not identified) who was infected. Staying at 2 m distance even in the street has far greater effect than installing this app on your smartphone!

                    I wonder how they intend to measure 2 m reliably? Assuming they intend to use bluetooth, different phones have quite varying signal strengths, and the antennas isn't isotropic at all.

                          Exactly - it is a joke. Yes, antennas vary a lot, even if the phones use the same BT chip. Lots of (most? all?) BT chips allow software control of transmission power, so even for a given phone model you can't be sure of the transmission power. When you walk past a person, if you both keep your phones in the pocket towards the other person, the signal essentially goes in free air. If you both switch the phone to the opposite pocket, the distance between the phones increase by at least four feet and the signals must pass through two bodies on their way.

                            In Norway, most definitely so. All of Hasse & Tage. Maybe not so much among teenagers, but "everyone" above 40 has great memories of movies like Äppelkriget and Picassos äventyr, and know many of the songs from the scene shows. "Änglamark", from the song in the Äppelkriget movie, has given name to a series of ecologial products marketed by the Norwegian Coop (maybe the brand is used by Coop Sweden as well). However, lots of their material is difficult or impossible to translate to English without significant loss. It was never translated to Norwegian, we listened to it in Swedish. Even "sannolikhet" cannot be translated to Norwegian without loosing the main point; we say "sannsynlighet".

                                Being less probable, doesn't make it an exception. And even if it would be, it brings no additional value to such app

                                    Deal :thumbsup: :-D

                                    M.D.V. ;) If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about? Help me to understand what I'm saying, and I'll explain it better to you Rating helpful answers is nice, but saying thanks can be even nicer.

Personally, even if there are privacy issues I think it is worth it for health safety. However, I think we need more than this. This is a reactive solution not proactive. We need something to let us avoid exposure, not just let us know when we've been exposed. Thoughts?

                                      People could just leave their phones at home, right? ;P

                                        I practically never have my phone in my pocket. It might be on table in front of me, e.g. if I have used it for some 2FA login on the Internet, but it might as well be at my bedside - I use it as my alarm clock to get out of bed in the morning. If I go to the supermarket, I rarely remember to pick it up. Usually when I go to work, I remember to put it in my backpack, but I don't take it out of there until I need it, which is quite rarely when I am at work. So it doesn't follow me to the canteen. This is not because I "leave" it at home, or bedside, or in my backpack, but because I forget it there. I spend little energy on trying to forget it less. I grew up with a fixed line telephone, located in the hall, not in the living room. I am bothered by people who demand their right to disturb me at any time, or their right to, through the phone, disturb a face-to-face talk I have with somebody else: Very few if any of my friends ever ignore/reject an incoming call, no matter what we are talking about. Forgetting to pick up my phone when leaving home is more a pleasure than a personal crisis (the way it is with some younger people). But the app wouldn't work for me.

                                          ...and (assuming your car is new enough) your phone then integrates with your car, and you can't prevent your car from relaying all that data. :doh:
