Big Five and friendship pattern
Internet and especially social networks redefined/degenerated words "friend" and "friendship".. "5 minutes" after registration to Internet social network you are flooded by people from all continents asking for adding them to your friend's list.

Climate change (split from Climate Change Tipping Points)
An increase in the Earth's average temperature will increase water temperatures. Cold water loving krill will die disrupting the marine food chain, which will affect all humans living near the sea. Some already hot areas in Africa and Asia will become even hotter, making it impossible for people to live there. The result will be a mass migration of people fleeing to more livable regions of the planet such as Europe, North America or Siberia. The influx of peoples will be massive and uncontrollable. This will inevitably cause irritation and protest among the indigenous peoples of the EU, USA, Russia and Canada. I have serious doubts about the validity of your statement that more people die from cold than from heat. Poor African and Asian countries do not make reliable statistics on deaths from overheating and e.g. getting a stroke.

What is the real difference between science and philosophy?
In parallel universes/multiverse every version of knowledge (except math) somewhere is true and some version of history happened somewhere.. If you are looking at a sci-fi movie (or normal movie), or reading a book, it happened, or will happen in the real world... ("Idiocracy" was comedy now thx to ex-POTUS is document) Scientists accept only the universe in which they are now currently. As you can examine only this universe. Have no access to parallel universes nor the multiverse. If you would have, you would end up as a crackpots anyway..

What is the real difference between science and philosophy?
Philosophy, (from Greek, by way of Latin, philosophia, “love of wisdom”) https://www.britannica.com/topic/philosophy Science is an applied philosophy. Measurement, analysis a real-world object and attempt to make a hypothesis and later a scientific theory based on the data acquired. Measurement -> data -> equation -> prediction of future results when the same inputs are given next time.

Energy cost of solar cells...
Solar panels are made of modules and they are made of solar cells. Unsure why do you want to separate them.. I think so energy is used in mining, extraction of rare Earth metals and regular metals, transport, melting etc. etc. It depends on abundance of metal in ore, distance travelled between factories and mines, and so on. Too many variables to generalise.. Typical solar cell is giving 0.5v to 0.6v with low amperage. If you have array of them you have solar panel which can give you more volts, ampers and therefor more power in KW. Divide net cost of production of a thing (without any subventions) by (local country) price of energy and you will have theoretical maximum number of KWh per unit. Exceeding this value would make production economically unviable. The cost of energy is part of product price.

How to pray?
It really doesn't matter. What matters are your good deeds (or at least lack of evil deeds)... (the problem is that different people interpret these words differently.. mostly misinterpreting them..) This is nonsense. The most of Muslims don't even speak Arabic language. https://en.m.wikipedia.org/wiki/Islam_by_country

Socket.error: [Errno 10060] when connecting to MQTT broker
Search net for Errno 10060. It is timeout error.. Third parameter is timeout. 60. Did you use such value manually or is it default? Default value can by changed. Use some TCP packet sniffer to see what commands are sent and received. No. You just learnt that you can connect to Raspberry not to the server which is at port 1883. telnet exact IP and exact port to see if there is connection made. TCP sniffer would also tell if script connected or not. This rises the question whether 1883 is the right port? Scan all ports to see which are open. If 1883 is the right port, try connecting with it locally from Raspberry to see whether connection is established. Tutorials "how to setup MQTT server on Raspberry" use localhost as IP, which is typically 127.0.0.1, which is accessible only locally not from remote machines.

Looks like Afghanistan is in Taliban hands...or VERY soon to be
If you're wondering who is responsible for all this s*.... (the answer is always the same, but through a couple of sockpuppets..) https://news.sky.com/video/afghanistan-taliban-leader-mullah-baradar-returns-12384306 "Afghanistan: Taliban leader Mullah Baradar returns after release from prison Baradar was arrested in 2010 in Pakistan but was released from prison in 2018 at the request of former US President Donald Trump's administration so he could participate in peace talks." (one might wonder about the objectivity of the August 2021 news, so one must go back to earlier records) News from 2018: https://www.outlookindia.com/newsscroll/taliban-leader-baradar-released-at-us-request-for-political-settlement-in-afghanistan-pak/1417930 "Islamabad, Nov 8 (PTI) Pakistan on Thursday said the Afghan Taliban's former deputy chief Mullah Abdul Ghani Baradar was released from jail at the request of the US as part of efforts to pursue a political settlement in war-torn Afghanistan."

What kind of element could never be naturally found in a star?
Stars are formed from materials that already existed in accretion disks. The later the star generation, the more heavy elements the accretion disk contains. At the end of its life, the Sun will consume Mercury, Venus, and Earth, so most of Earth's existing atoms here will become part of the solar red giant.

Delta variant, breakthrough infections and related consequences
ln democratic countries politicians want/must to follow voice of the voters. Making unpopular movements (even good at the end for the community) is straight route for being eliminated in the next election. Not without a reason POTUS do more unpopular actions in their 2nd term than in 1st term. Even worse if such antivaxxer, disbeliever in Covid-19 or human made climate change, take a seat becoming influential politician.. such a person will reverse everything good what was done (e.g. withdrawal from the Paris Agreement).. They were brainwashed that COVID-19 is a hoax. I met such people (when they were returning from anti-lockdown protests) and talked with them face-to-face.. Showing them this video: ..imagine what disaster can make such anti-lockdown politician after being elected..

Political Humor
You've watched too much movies with Christian Bale.. "Vice", it was a good movie, but who said it was absolute truth.. ? I mean, he was sockpuppet as well.. Ps. Ohh. . we are in the wrong thread.. Starting political discussion in the thread which supposed to be humourous.. maybe copy & split?

Lifetime of LED replacement light bulbs.
"Running hot since ever" or "running hot at the end of their life just before failure".. ? Design issue? In either case: check their voltage and amperage.. If electronics is failing, it can give too much voltage and/or amperage which will damage LED too.. (If you don't have) buy microscope and IR camera for these ultra small boards.. compare still working LED v/a with already broken to find differences. Broken part is often overheating with even low voltage (plug to labs power supply (with controllable parameters)) thus it will be visible on IR camera..

What do the following headlines tell us?
Some would say: "Judgement Day is close".. (and people here push me hard to accelerate..) I am asking them: why do you hate your life? so why are you doing what you are doing to yourself.

Updated to latest forum software
Thanks Dave. Looks good now. At least devs made it configurable.. ps. Somewhere (e.g. user profile) it still rounds larger quantities to the nearest 100.

Updated to latest forum software
Looks like crappy update of the software.. On PC user can hover elements by mouse to show details, on mobile there is no such way you can hover element to display bubble with details.. Rank is hidden under "rocket icon" which displays only after hovering it by mouse on PC.. Number of posts, reputation points, rounded to the nearest 100. You don't even know how many you have. Maybe it is editable in configuration?

Making Cars More Efficient
...."ignorance is bless"... (So they said too) "1st world problems"... in 3rd world they have "will we eat today?".. The more important aspect of flood of cars is that people will spend hours in traffic wasting their precious time of life fruitlessly. 2h per day is 12.5%, 4h per day is 25% of 16h human day activity..

Solar electric generation, at unusual place...
Tesla's solar roof is unrecognisable from normal roof.. so maybe some day somebody will also make such asphalt for roads. Price, efficiency and durability are the main concerns. If they would in full light produce magnetic field it would allow levitation slightly above the road and reduce energy consumption by cars which would not have to worry about friction anymore. Once accelerated car would be flying a couple cm above the road bothering only about air resistance.
