  1. Apart from the concerns you have in your mind: How do you ban a website in a democratic country? It doesn't even work in non-democratic countries.. One can buy a VPN. Second one can buy a dedicated server. The third can change the DNS to a completely different one. Yet another one can intercept a computer in another country and remotely use it.. or you can hire someone in another country to relay questions and answers by phone/email/file or whatever.. You would have to ban the entire Internet (dismount cables, cell-towers etc.) to prevent one person from using a website if that is their desire.. What privacy concerns?!
  2. Don't drink anything after 6 pm if you plan to go to bed at 10 pm.
  3. Open a normal terminal and use: cat /usr/local/include/stdio.h Does it work? If you also have "Permission denied," open the terminal in administrator mode. List contents of /usr/local and /usr/local/include to see if you have the right files there. Finally, use the: chmod -R 777 /usr/local/include/ -R should do it recursively with all files and subfolders. (check the manual e.g. man chmod) Before resolving the "Permission denied" error, there is no point in analyzing the rest of the messages.. You can use: cd /usr/local ls -l or cd /usr/local/include ls -l to see what permissions are assigned to files and folders. chmod 777 filename means read+write+executable access for every administrator, user and guest (which is the weakest/dangerous one) Refer to the manual: https://man7.org/linux/man-pages/man1/chmod.1.html
  4. Paraphrasing it: If the application records your videos, photos, selfies, it can immediately knows who you are (e.g. it can search in an external database with faces e.g. Facebook, old Google+ or Twitter etc.) and your family and friends. USA-IT companies do/did it all the time ("automatic photo tagging") https://www.wired.com/story/facebook-drops-facial-recognition-tag-people-photos/ From 2010 to 2021 is 11 years.. Enough to gather their data even for external FB user. If the app shows things the user has clicked on, then after a while it knows which topics people are interested in (clicked) and which are not (skipped). If the application connects to the Internet then it knows your IP address, the less valuable/precise IPv4 and perhaps the more valuable/precise IPv6. Any application owner that connects to the Internet has server logs.. Public static IPs used by dedicated servers have well-know exact locations to within a few meters i.e. you go to McD, KFC, PizzaHut, and connect to their free open hotspot and (other) companies could know you're at the restaurant. If the app knows which WiFi SSID/ESSID you are connected to, it knows your almost exact location on the world map. Google is trying to fight it (so they are the only ones who know, which you can check in your Google Account). You can explore how this works for developers (they need to find a new workaround in newer versions of Android): https://stackoverflow.com/questions/21391395/get-ssid-when-wifi-is-connected Older Androids let the app know the phone's IMEI, as well as the phone number. Newer versions return nulls. So companies have to force the user to give them the phone number, and then it is verified by SMS.. 2FA even gave them a good excuse to do it all day. When I started writing scripts in Python in March, Google started showing ads like "40k per month salary in your city" and similar ads with jobs.. Should we ban Google? I haven't seen any report clearly (to the developer) showing evidence of malfunctioning apps from TikTok, Huawei or any other Chinese company's app where they downloaded more data than US companies IT.. Any application that executes code it just downloaded from the Internet can do bad things, but it won't be detected for a long as the target (the person being attacked) is identified and the special code is uploaded only for this person. It can take minutes, seconds, milliseconds for this code to be on the device.. and then it is wiped out by itself.. Malicious applications that have built-in malicious behavior are much easier to identify without any doubt. Developer can decode it and tell what code is doing or pass it through soapbox to see malicious behavior. An application that identifies person by person and has an auto-update function must have an infrastructure that allows their programmers-hackers to inject malicious code into only one exact person in the world..
  5. They would have to be an embedded in operating system to make it faster and easier than it is now.. i.e. not really faster, just a few clicks and seconds..
  6. If it is used for customers, it is just such wordplay i.e. marketing bullshit.
  7. There is the easy way and the right way. An easy way is to use a 3D pen. https://www.google.com/search?q=3D+pen+device Very cheap, uses the same stuff as a 3D printer, so it's readily available. It's such a 3D printer at hand (gluegun can be used too!). (an electronics engineer uses gluegun for everything) The right way, withstanding much more: 3D scanning/reproducing the original object in a 3D application, and then printing it. 3D printed laundry rack connectors + some metal tubes.. can be made for a fraction of the price of the original thing in the store.. Then sell 3D project, and you can earn more than ever in your life..
  8. Buy a ~ $400 electric vacuum pump from any chemistry lab equipment store and tell me which PLA, PET, ABS, etc., will survive a few minutes in an environment with a pressure close to 0 Pa, once the device is activated.. Make a chart in Excel/Spreadsheet.. I tried to find the nearest chemistry lab store in your area selling a vacuum pump in Gloucestershire, but I was inundated with some far too expensive commercial used vacuum pumps.. 3D printing uses: PLA, PET, ABS, ASA, resin.. If you want to know their properties, look online. Temperature - not very resistant.. 200 C is used for melting PLA, 240-260 C for almost all of them used in FDM.. But temperature alone is not the only parameter, there is also pressure. Which is not given by producers. Smart guy, like you, with <$1k would put 3D printer inside of box 1x1x1m and use vacuum pump to get out of the air from it while printing to see what happens.. and make a video from it.. i.e. can you 3D print in ~ 0 Pa environment.. can you 3D print in < 100 Pa environment.. can you 3D print in <1000 Pa environment.. etc. etc. a series of useful experiments..
  9. Seriously? What amount of light is on the real ocean bottom? What amount of nutrients (in the prehistoric sea) are on the ocean bottom? Check the average depth of the world's ocean.. https://www.google.com/search?q=average+depth+of+the+world's+ocean The existence of organisms on the ocean floor (except for volcanoes) depends on "marine snow": https://en.wikipedia.org/wiki/Marine_snow
  10. Exponential growth in the non-mathematical physical world (i.e., with limited resources) is just temporary..
  11. 3D resin printing (UV light)
  12. @studiotThere are different 3D printing technologies. Fused deposition modeling (FDM) is the most common and is what I use. I don't see mention of technology they used. Clickbait for newbies. "Everything" around you, that is less than 5 years old, was 3D printed at some point by engineers creating a prototype of the thing in question. I have 3D printed vodka glasses.. FDM is good for the environment. You can take the plastic PET bottle and convert to filament that will be used for 3D printing. This means you use up the plastic you buy everyday and have free filament for 3D printing. Add in solar panels and you have a machine that runs completely for free.. There are two main techniques: 1) using a hotend from a 3D printer to heat a PET bottle to make the filament, 2) use gluegun for the same effect.. So you could go to a landfill and find enough PET bottles to make whole rocket body for free..
  13. ...it is not about information but how it is delivered.. i.e. one can make and hacker app, which will deliver (misleading) information.. "To me" means to whom?
  14. That's true.. The problem, is you.. Your stupid, primitive method of responding like xyzt's responses in his last days.. If you don't want to spread knowledge, simply don't write posts.. You keep belittling the responses of other members of this forum who wanted to answer the OP's question in the thread (any thread!) instead of answering the OP's questions.. If you want to solve this equation for the real what is the real ancestor, let's go back a few billion years ago to the time of primitive microbes.. and your primitive "It's still wrong even when you add the reference" means you are wrong.. It is impossible to say where single cells originated and then when they became multicellular.. It is impossible to say where inorganic matter became "alive".. Do you feel like an idiot after what I just wrote? Change nickname to nitpick. No surprise nobody ask you for a dinner. Nobody likes assholes. Greater Easter is coming, change attitude, maybe somebody really desperate will ask you for your attendance.. Which is very dubious looking how you overall behave.. AFAICS, the OP asked for genetic links between Americans, British and Australians, you should ask ask "for how long?" / "percentage of population" or similar questions.. Instead of them, you started rub against a members of this forum who tried to answer.. Who cares what you write such stuff? OP certainly is not interested in your private wars with every other person on this forum.. he is interested in the answer - you have not gave it.. I can give a definitive answer - everyone in this world is brother and sister.. Satisfied? ps. Until some third-party alien lands and mixes with you.. ps2. Stop being an asshole, John Cuthbert. Can't you? Only for Great Easter. Try it at least once. Possible or not possible achievement?
  15. Many "stowaways" begin to be harmful when the host's immune system weakens due to age or illness, such as e.g. HIV/AIDS. Normally harmless microbes begin to cause harm to their host..
  16. You are talking about mutualism. https://en.wikipedia.org/wiki/Mutualism_(biology) "Mutualism describes the ecological interaction between two or more species where each species has a net benefit." https://en.wikipedia.org/wiki/Gut_microbiota "The relationship between some gut microbiota and humans is not merely commensal (a non-harmful coexistence), but rather a mutualistic relationship."
  17. From the net: "There are about 2 kilograms of bacteria in the human body, forming the so-called physiological flora." "Because of their small size, however, microorganisms make up only about 1 to 3 percent of the body's mass (in a 200-pound adult, that's 2 to 6 pounds)". If they weigh 2 kg, they have to eat something that the human ate, so the human has to eat more to compensate for the loss. A person with more mass must expend more energy to accelerate and move. Microorganisms excrete metabolic products too.
  18. ..which means that the programmer will not learn how to do it correctly so as not to lose memory and how to reduce memory consumption..
  19. One particle colliding with another particle gives up some of its kinetic energy. 1st one is decelerated, 2nd one is accelerated. Typical interactions: photon-electron, photon-proton/nucleus, electron-electron, electron-proton. YouTube animation showing the interactions of photons with matter:
  20. What I have shown on this map are non-Latino White Americans. All of this comes from the Wikipedia Americans page: https://en.wikipedia.org/wiki/Americans#White_and_European_Americans Latino Americans (mainly Hispanic-Americans) are listed under different category. ps. Sorry I didn't include the reference in my previous post and causing confusion.
  21. Most white Americans are not from Britain. There are only 7.1% of them:
  22. I wish we had more physicists than politicians, soldiers, humanists, etc. etc. combined, you could understand me better.. I have feeling that you took my words up-side-down.. You should say (way too late) "I know a lot of theoretical physicists who do it for free without getting paid and still do it.".. THEN put this in your message to me for it to have any meaning in the discussion.. If someone does theoretical physics and has no results and takes money for it, it looks even worse..
  23. The same as "time travel", "parallel universes" etc.. Ordinary people do everything for money.. No money, no work.. ps. This would be an interesting topic for a "how much Thomas Swanson" spent in physics doing something he wasn't paid for (and seeing the results obviously!)..
  24. Not as seriously as you.. the all your threads, I can remember, are about it..
  25. Even simple living organisms send out visual, audible or chemical signals to inform about predators, danger, food sources or other information. The more complex the organism, the larger and more complex the dictionary. Through observation - I could see a correlation between when you say a word and a thing, an action taken by you or someone else.
