  1. In a limitless environment i.e. your own building with enough money, just for heating, you should consider taking solar collectors. They heat water or other fluid in pipes going around house. I would have TV, computers, 3D printers, refrigerator, washing machine, and water boiler (water for bath) plugged to them all day long.. Change habits, such as bathing, washing clothes during the day rather than in the evening.
  2. It is not always the case: https://community.letsencrypt.org/t/lets-encrypt-not-automatically-renewing-certificates/70678 https://support.cloudways.com/en/articles/5128853-fix-issue-of-let-s-encrypt-ssl-not-renewing-automatically
  3. You can/should 1) remind owner about upcoming expiration date in advance 2) ask owner of the server to extend admin list to a few people who will be able to do it.. Set an alert in cronjobs.. The SSL certificate will expire in 43 days.
  4. Because you did not do what I asked to do years ago - there must be created alarm for mods starting a couple days before the next 16 October 2023,2024,2025+.... There will be probably second problem with expiration of SSL certificate... Check when it has expiration date. OK. I will do it for you... https://www.sslshopper.com/ssl-checker.html#hostname=www.scienceforums.net "The certificate will expire in 43 days." This shows a severe problem. There should a group of people who have readily access to the server and will be able to pay bills for server, domain and certificate, and edit the settings. If there is one admin who has the all things on an encrypted and password-protected machine, his or her disappearance for whatever reason will be the end, as nobody will be able to pay bills in advance prior expiration date...
  5. Pro V.P. people the main motto is: "Après moi, le déluge".. ("After me, the flood")
  6. @iNow OP specified, said "both cities".. see above.. Undoubtedly.
  7. Neither Seoul nor New York grounds are used by farmers.. so, what actually want do you to compare?
  8. In long term - obviously.. In long term - obviously..
  9. People don't want to be here because they are in pain. Physical pain, metaphysical pain, existential pain.. Understandable. Some/most sources of pain can be cured/repaired. "Success" = "existence of human beings one day longer"....
  10. Eternal life or rather eternal existence.. ? ..in the midst of artificial intelligence that will ask the question "the meaning of life?" or other mortal beings asking questions in a scientific forum like "What does success mean?"... ...your spectrum is too short...
  11. It depends on the temperature of the washing machine. There are 90 C, 60 C, 45 C, 30 C.. Bacteria can't survive excessive heat. Bacteria cannot thrive in the absence of food.
  12. Pillow #1 != pillow #2.. They differ.. You have to have information about them to decide. I wash my pillows entirely in the washing machine. They are designed for that. They are allowed to be washed in the washing machine. There is a washing procedure listed on their label, etc. etc. So, basically, read the label to find out.. I try to wash the pillows every few months. One every month. One every two months. If you don't think they are "fresh," you should wash them. BTW, pillows are cheap. 10 euros for 60x50 cm one.. The key is to use 1600 RPM during spinning in the washing machine. The more the better. After that, or x2, pillow or quilt, should be almost out of water and almost dry. I washed my pillows and quilt maybe 5 times in 2022, and will do more this year..
  13. Not really. It is connected to giving/sustaining life. Just because if you don't drink, you die. Nonsense. In Christianity it is just a symbol of reborn after you wash you're clean i.e. flushed all previous "sins" (even if you did not have any like newborn).. Nonsense. Primitive people have primitive superstitions. Nonsense. The creator of the Universe likes quantum physics, if you did not notice yet.. Nonsense. It can be used to create fusion reactor, or nuclear weapon.. For primitive people, indeed, something "magical".. Nonsense.. ps. BTW, you "forgot" to mention Ganges... "The Ganges is the most sacred river to Hindus. It is worshipped as the goddess Ganga in Hinduism. The Ganges is threatened by severe pollution." https://www.google.com/search?q=ganges+holy+river
  14. This is a clever question in physics. Do you know the equation of the distance traveled by an object falling at a given acceleration? Reverse it to have time as result and distance and acceleration as parameters. The distance is known. The acceleration is known. Only the time is unknown. Have two such equations, but with different accelerations of 10 m/s^2 and 9.8 m/s^2, and divide them together and multiply by 100% to get the percentage difference, and subtract to have the absolute time difference in seconds.
  15. Remembering how Muslims around the world reacted to the collapse of the World Trade Center, this will be a very quick test.. Astonishingly, even those who are regularly paid by the U.S. and their countries are completely dependent on foreign aid.
  16. It is very variable from person to person. One can have multi-million loan and/or company on the edge of bankrupcy..
  17. ..my 10 year old would be billionaire, if would be so stupid to bother about the money like typical human being..
  18. At least you had the honor of talking to the creator of the Universe..
  19. To implement such functionality sound waves can be used. Buy an Arduino and an ultrasonic distance sensor. Here's a tutorial on how to make it work: https://create.arduino.cc/projecthub/abdularbi17/ultrasonic-sensor-hc-sr04-with-arduino-tutorial-327ff6 It is used by automatic robots, for example, that clean the floor or to light up rooms when someone enters them.
  20. You reboot the system when Microsoft wants you to, i.e. after downloading a major update such as drivers or the system.
  21. "Better late than never".. But it is half-done achievement. Video of the explosion (download/rerecord by a desktop recording app such as VirtualDub) https://t.me/bazabazon/13718
  22. It is possible to cool the Earth by sending a "very large" number of satellites-mirrors into cosmic space, where they will reflect sunlight and prevent it from reaching the Earth at all..Satellites can be remotely controlled to control the amount of energy reaching our planet. Alternatively, cheaper and easier, without an important remote control, spread gas between the Earth and the Sun. Alternatively, white balloons that will reflect sunlight. But that would be a devastation/pollution of the sky. But it is OT, as these ideas would decrease global warming rather than directly fight with algae.
  23. People who own laptops often simply push the flip cover down, which hibernates the system, instead of shutting it down. This causes problems in some situations. I know that Windows Media Center (the TV Tuner application) in Windows 7 is buggy and consumes the entire disk until the system is properly shut down and restarted (which obviously kills services). I found a workaround - shut down only the service in the Administration Panel. The files are locked permanently by the service - no cleaning, deleting, etc. can remove them while the service is running. In Win10 WMC was removed, but some other service or app can have similar issues.
  24. I advise you to calculate the volume of water, calculate the energy needed to lower the temperature, calculate possible energy harvested per device (not just peak maximum), and calculate the number of devices that will be needed.
