Calm down. I was in the middle of edit, searching for videos to attach.. writing/replaying on mobile is PITA.. Viruses (in aerosols ejected by ill people) can infect you also through eyes.. https://www.google.com/search?q=virus+infection+through+eyes https://www.thelancet.com/journals/lanmic/article/PIIS2666-5247(21)00040-9/fulltext

When people ask me about masks and COVID-19, I am showing them videos captured in slow motion, thermal spectrum, comparison of how much different kinds of masks release aerosols around ill person:

When we are at debunking the myths: anti-vaxxers are not the one who just don't take vaccines, but the one who claim that vaccines are on purpose secretly made harmful by some unidentified group ruling the world to harm people and cause depopulation, autism, cancer etc. etc. Basically conspiracy theory..

@Theodoros Kiriakopoulos Okay. I created Elo calculator spreadsheet for you using algorithm description from the website: https://metinmediamath.wordpress.com/2013/11/27/how-to-calculate-the-elo-rating-including-example/ OpenOffice Spreadsheet file: Elo Calculator.ods I used constant K-factor 20 as it appears to be used by Omni Calculator. You can change it in the J column. There seem to be also problem with how to round fractions. Floor/ceil them or >=.5 treat as +1..

https://en.m.wikipedia.org/wiki/Glicko_rating_system You should say "A team or a player who has 20 wins in 20 games may be better than a team or a player who has 40 wins and 20 losses in 60 games.".. ...because it does matter with who they played and how much gained experience.. I found elo calculator for you: https://www.omnicalculator.com/sports/elo Enter 1500 for both players. The result is 1510 vs 1490. Enter 1510 for 1st player and again 1500 2nd. The result is 1519.7 vs 1490.3. Enter 1519.7 for 1st player and 1500 2nd. The result is 1529.1 vs 1490.6. (repeat procedure) Clearly it is not what you claimed.. The larger difference between players result in gaining less for higher level player and losing less for less experienced player (if they win/lose accordingly to higher/lower ratings) Conclusion is that you did not pay enough attention studying rating algorithms.. I suggest using OpenOffice Spreadsheet or Excel or if you are familiar, some computer programming language.

Don't believe in Forbes list and similar billionaire's lists too much. They take into account only what is public available i.e. current stock price.. Debts of the companies are often kept secret to not fear investors.. (regular people often do the same, have apartment and car, with 30y+ credit, but people around them have no idea it is all for credit and are jealous.. actually such person can have negative amount of money, if they would sell everything) Do you believe Amazon is mega corporation? Right? They were, quarter by quarter, losing money of investors doing retail selling business.. I have no idea how do they do it with such worldwide public recognition. Normal company, not listed on stock markets, would have to file for bankruptcy a long time ago.. They started earning money after they started AWS (aka "Amazon cloud"). I bet ya, if they have to choose business retail vs AWS, they would prefer cloud..

Modern sport is a mess. In many disciplines person has to start very early, or won't be able to compete with others on Olympics level. Have no normal childhood. Doesn't go to normal school as it would collide with sport. Person who started at 8 vs person who started at 15. The first one has 7 years more experience.. Entire life is subordinated to the training plan. In majority it is plan of their parents than child. They have no normal day work job. Sport is their job. Have to search for "investors" which will give them regular monthly payments. In return sponsor receives the rights for somebody image in medias (which can be worth something in capitalistic country in the future and used for advertising, if (and only if) child sportsmen-to-be will have good results in sport and gains general public recognition). Only a few can reach to the top. The rest childs sportsman-to-be remain without normal childhood, jobless, unknown to public not widely recognizable, bitter. Without proper education and teenage social life/skills, they have problems with existence and relationships after finishing their sport career e.g. due to injury.

Some sources inform that public debt of EU exceeded 100% GDP in Q1 2021: https://www.google.com/search?q=public+debt+in+europe+2021 The situation is very similar all over the world: https://www.google.com/search?q=japan+public+debt+to+gdp+ratio Japan public debt was 235% of GDP in 2019, and 256% in 2020. (Wow!) Now governments want to increase taxes to get these money back from ordinary people and enterprises (which will pass it on their customers and workers). At the same time they extraordinarily waste them on e.g. war equipment which ends up life on e.g.: The equipment used in Afghanistan, Iraq, Syria will also end up in such a graveyard. All your taxes went on (and now government debt) Governments are "persuading" financial institutions to lend them money and banks do so. Have no other choice as e.g. rates of interest (which govs control) are the lowest in the history and bonds seem to be the best way to "invest" extra money from their point of view (i.e. more reliable than customer credit or enterprise credit). Half-good if they are invested in something useful and longterm existing. But there is large amount of groups of interests behind politicians, supporting them to get to senate, parliament etc. (in US it requires 1m+ "investment") which they have to pay the bill later at office. Doing large infrastructural projects there is vast number of ways politicians, their families, their friends and friends of friends, groups of interests, can get rich and get a bit of chunk from a big pie called state budget.. Which department ever asked for less in following year than in previous? Because previous was too big to spend it all? No! They will spend everything to every penny and even exceed (and (ab)use on complete stupidities fearing to decrease year-by-year department's budged). Bottomless pit.

As it is just entertainment, I would use a large LCD/LED display with Earth seen from cosmos with an interactive ongoing simulation showing the rising desert border as temperature rises, more frequent and larger tornadoes, changes of sea level and flooding of current low elevation lands etc. etc. If it is already in the future, the Earth on display may have a different coastline than we know today.. The viewer will have WTF impression the first time will see the new coastline. Here you have the predictions: https://www.google.com/search?q=coastline+simulator+global+warming (switch to image mode) And video: https://www.thesun.co.uk/tech/8386736/rising-sea-levels-simulator/ e.g. Florida? What Florida? What Mar-a-Lago? ps. I am doing a facepalm on hearing somebody buy or build something in Florida..

...You might get "access denied".. Copied from the net: "The default size of hiberfil. sys is approximately 40% of physical memory on the system. If you want to disable hibernate mode without turning off Fast Startup, you can reduce the size of the hibernation file (hiberfil. sys) to about 20% of your RAM in Windows 10." and "How do I change the size of my Hiberfil sys? Change the size of hiberfil. sys in Windows 10 Open Command Prompt as administrator. Type the following command- powercfg /hibernate /size <percentage> Hit Enter."

How many particles is in your body? How many information can be send per second? Therefore, how long it will take to send all your state from B to A, or A to B? If somebody is able to do what you described, instead of teleportation, could make backup of himself or herself at exact date, and if accident happened and/or died, recreate body from backup.. If somebody is able to do what you described could run computer program analysing backed up data of the body to find cancer, mutation, anomalies, illness etc.

??? Internet forum (like this one) is an example of social network.. They are "pushing malware" to intercept your device and use it and eventually stole your money and/or identity. Hackers will automagically disappear? How? Honestly, using the net in ~ 1995 was a nightmare...

@studiot To be able to catch discrepancies between presented versions of the history, you would have to compare books, articles, movies and other materials in different languages (countries involved) about the same event. e.g. what China authors wrote about 1st and 2nd Opium Wars, versus what English authors wrote (in 2nd also French and Russian versions). The older event is analysed, they can't even agree about quantity of forces involved and casualties of some battle.. with even less data about civil casualties.. History of science is in completely different category than history of wars, conflicts and politics between countries and nations. It is history of discoveries. Unattractive for populist politicians to alter on purpose to push their version..

"History is always written by the winners". So, what you read and learn in historical books in majority are lies, (mis)interpretations, concealments of unpleasant facts, etc. etc. Distortion of the truth is part of "patriotic" political activity.. Weak minds are easy to manipulate by populistic politicians..

Typical way ray-tracing is implemented is divide geometry to triangles (at startup) and find intersection between each triangle and ray (origin and direction vectors).

..you are doomed not because water is shipped half the world in plastic non-returnable bottles... but because politician's the only response to any ecological (and not ecological too) problem is: INCREASE TAXES. Shortage of water? Increase water costs. Too much trash? Not segregated garbage? Increase garbage collection costs.. etc. etc. The all people on the bottom of economy, are exploited the most, and suffer the most, and they are discouraged from any pro-ecological activities.. When I see politicians talking about yet another increase of taxes, I know they don't have idea what they are talking, they don't have idea what they are doing. And ecology, global warming, is just yet another pretext to increase taxes.. Instead of true fix.. The example of ecological problem: do you want to have streets free from beer glass bottles? Instead of deposit for the bottle (which is transferred to the end client), shop should be able to sell only 95-98% of quantity of beers which bottles clients returned. e.g. in the first week they sold 1000 beers, they must get back 950-980 bottles back from clients, to be able to sell another 1000 beers the next week. If they won't collect them, they cannot sell beer. Shop will beg their clients to come with empty bottles. Otherwise they won't earn money on beer. Glass bottles returned to the shop, are reused without having to melt glass and/or fresh sand, which saves energy (coal/gas used to heat furnace etc). Trucks have to return plastic containers, with bottles, or without bottles, anyway. So more optimal is if they are full of empty bottles. It's fight between industry producing glass bottles with ecology. The less people will return empty undamaged bottles, the better for companies making these bottles. They will get broken glass from trashcans anyway, melt it, and sell it once again to beverage companies. In classical method of solving this issue i.e. deposit for the bottle, shops regularly refuse to accept empty bottles ("because they were not purchased here" or whatever they want reason). Clients are pissed off. They paid for beer in the bottle, paid cost of deposit for the bottle, and they can't get their money back. Bottles end up in trash, are smashed, and make even more garbage on the streets, and cities look like garbage dumps...

Many commercially sold fruit trees, and other plants, can be asexually reproduced i.e. vegetative reproduction: https://en.wikipedia.org/wiki/Vegetative_reproduction https://en.wikipedia.org/wiki/Fruit_tree_propagation https://www.google.com/search?q=vegetative+reproduction+apple "Apples are mostly propagated by shield budding, which gives a high percentage of success. In shield budding a single bud along with a shield piece of stem is cut along with the scion and inserted beneath the rind of the rootstock through a 'T' shaped incision during active growth period." https://apples.extension.org/apple-tree-propagation/ "Asexual Propagation Because the seeds (sexual propagation) produced by apple fruits are the result of cross-pollination, the resulting seedlings are not genetically identical to each other or to the “mother” tree. To create multiple copies of the same cultivar, asexual (i.e., not sexual) — also called vegetative — propagation techniques are required, and apples are easily budded and grafted." You don't buy "apple tree seeds" but ready "apple tree seedlings". "Apple seedlings are small, propagated tree stems grafted onto a hardy root stock. Seedlings are ready to plant and grow in the home landscape once they have grown in a propagation environment for about one year. The seedlings grow into a producing apple tree six to 10 years after planting. Proper planting and care of apple trees at both the seedling stage and as the tree matures makes growing the trees a rewarding process." https://en.wikipedia.org/wiki/Grafting "The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades. " Currently existing commercially cultivated fruit and plant species are result of centuries of careful breeding and mixing. Wild apples are (typically) small, sour and green. Farmers spend centuries to create big, sweet and red apples.

@Kartazion If your machine has HTTP/HTTPS server, you can make simple PHP script which will make/update file by file_put_contents() somewhere, and examine date and time of the last access of the file from bash script. If access time is more than 5 minutes ago, refuse SSH connection. So procedure of logging would be: open browser on mobile or so, visit your top secret PHP script location, then login to SSH or whatever else. If somebody does not have idea that must visit website with the right URI with script first, will be rejected.

@Holmes Thanks @studiot for bringing this interesting information. https://www.nationalgeographic.com/animals/fish/facts/clownfish "Changing Sex" "Surprisingly, all clownfish are born male. They have the ability to switch their sex, but will do so only to become the dominant female of a group. The change is irreversible." https://en.wikipedia.org/wiki/Sequential_hermaphroditism "Sequential hermaphroditism (called dichogamy in botany) is a type of hermaphroditism that occurs in many fish, gastropods, and plants. Sequential hermaphroditism occurs when the individual changes its sex at some point in its life.[1] In particular, a sequential hermaphrodite produces eggs (female gametes) and sperm (male gametes) at different stages in life.[2] Species that can undergo these changes from one sex to another do so as a normal event within their reproductive cycle that is usually cued by either social structure or the achievement of a certain age or size.[3]"
