Computer programmers use 'true' and 'false' all day long in software. Logical (boolean) operators return "true" or "false". e.g. if( x > y ) then do something #1 else do something #2. However, we can imagine a bug where the result of an operator depends on the result of the same operator (which depends on the result of the same operator etc.), resulting in an infinite recursion that is infeasible and will cause the software to crash (stack overflow due to not having infinite amount of memory).

What AI? Chat software is not AI. Companies abused the word too much..

Except that the zebra lives in southern and eastern Africa, and the tiger in Asia..

The fix is ultra easy and does not require the presence of an administrator as long as the BIOS is not password-protected, PEX is not used, system drive is not password encrypted, and booting from USB is enabled. Download Linux Live pendrive e.g. Kali Linux Live, save to a flash drive, boot from the flash drive on the target machine, mount the Windows system partition, rename folder C:\Windows\System32\Drivers\Crowdstrike and reboot the system. Administrator privileges are not needed, just Linux Live on a flash drive. You can hack into any Windows or Linux this way, as long as you have physical access to it.

Oil has some uses besides being a fuel, such as people making plastic from it. Plastics can be produced from a variety of sources, for example, thermal decomposition of bioethanol (i.e. ethanol from fermentation of plants) creates ethylene, and then polyethylene or other compounds can be created from it. The question is at what cost. Land used to grow crops for bioethanol is not used for food production, which increases its cost. There are attempts to directly create ethanol from air https://www.google.com/search?q=ethanol+from+air+produiction Crude oil is the result of the decomposition of living plants and animals, compressed over millions of years. So whatever can be created from crude oil, gas or coal, can be simulated simply by using the sun and carbon-rich compounds and water..

Send it to hungry Nigerian orphans..

I guess everyone would prefer to, copy and paste of the text of this document instead.

Nobody read. 0 downloads... Which is expectable on our science forum.. as people here are slightly above average.. It's not a PDF. Worse. Some Windows/Microsoft crap.. https://www.google.com/search?q=docx+exploit If somebody does not update system, it is pretty fresh exploit from 2021, hacker can use this to hack in Windows using docx format: https://www.exploit-db.com/docs/50577

A slightly misleading comparison, because not taking into account their populations. https://www.google.com/search?q=hippos+population "around 115,000 to 130,000" https://www.google.com/search?q=lion+population "between 23,000 and 39,000 lions" 130k / 23k = 5.6x more. So if lions had a similar population to hippos, they would have ~ 124. If you're fishing on a boat, it's much easier to inadvertently get too close to hippos than to lions in national park. Nice interactive maps with populations of these animals in each country: https://worldpopulationreview.com/country-rankings/hippo-population-by-country https://worldpopulationreview.com/country-rankings/lion-population-by-country BTW, "It has been estimated that about 1,000 people are killed by crocodiles each year." https://en.wikipedia.org/wiki/Crocodile_attack

Use email aliases. If there is a server leak, only the mailbox alias will leak, not the real e-mail address. You can see who is sending you unwanted e-mail because each service has a different alias. ..especially if you will use your real name, real email address, real domain address, real phone number.. Social media these days often don't use static plain HTML that is parsed like in the old days. Instead, they use dynamically generated HTML output from JavaScript or similar by user browser. Twitter was/is leading at it. FB second. This means that every time someone reaches the same URL, they will or may get something different. This is useless to search engines. So they (the search engine owners and the social networks) created a hidden b2b APIs. In a forum such as this, searching whether "X" said "Y" is quite easy. In social media, it's almost impossible. Public developers API for FB https://developers.facebook.com/docs/pages-api (these commands will work for your own FB account and pages) If you bother about your privacy, don't use social media, don't use Google Play Store and Goggle Account, and Apple ID..

Yes. Obviously. If you run Linux live, you can see their UUID in, for example, the /media/$USER/.. folder. or in GParted.. Windows even stores all the UUIDs of the flash drives ever connected to the computer in the registry..

Then you should express your thoughts in a more detailed and less ambiguous way.. Everyone on the forum wishes that..

..starting programming with JavaScript is one of the worst decisions someone who wants to learn programming can make.. Web browser + NotePad = you don't have a debugger, documentation, completion, errors and warnings are hard to get, you don't have the tools a newbie should have.. Your whole post is silly.. and childish...

Farmers producing (more profitable) biofuels don't produce food. Crop acreage is fixed. This raises the price of food for people. Biofuel can be produced by (GMO or not) algae or microorganisms, directly from CO2 and H2O with sufficient solar energy.

Nof Internet? Computers? Phones? Scienceforums.net? You've got to be kidding.. Survival in cyberspace is more challenging..

The problem is that you started this thread in a childish way.. for such paraphrasing you need to have enough reputation points. Going to the Moon was a far easier.. Sometimes fighting with physics and engineering issues is easier than fighting everyone on the planet, politicians, businessmen from coal, oil & gas industry, employees from oil & gas industry, miners, farmers, people loving fossil fuel driven cars (even if they have never seen or driven an electric car), etc. etc. Good video. 13m. Summed up the energy industry. To stop being a selfish bastard would be a good start.. People (and countries with net exports of these commodities) who want to maintain the status quo in the coal, oil and gas industries, directly or indirectly, are the biggest blockers. https://en.wikipedia.org/wiki/Après_moi,_le_déluge

If your definition of an "energy crisis" is similar to Wikipedia, i.e. https://en.wikipedia.org/wiki/Energy_crisis Energy crisis indeed happens every a couple years, on a small scale, in different countries. We can see them on charts as peaks in oil, gas and coil prices. Countries that lack natural resources, mainly fossil fuels, are particularly susceptible to this. The key is dependence on other countries and their willingness (or not) in delivery the goods. Rising coal, oil and gas prices on world markets cause secondary waves in completely different areas of such a country's economy. COVID-19, War in Ukraine, Israel vs Palestinian conflict, conflict in Yemen, all them causes more or less visible disruptions in transportation and production of oil and gas, and transport of other goods. Modern food production costs rise with the price of fuel, transportation costs rise too. This leads to a loss of customers and can result in the bankruptcy of otherwise good companies.

p+ + p+ -> D+ + e+ + ve + 0.42 MeV (average half of it goes to positron and half with neutrino) i.e. 0.42 MeV = 420 keV from initial 938.272 MeV/c2 x 2 = 1876.544 MeV/c2 (~ 1.9 GeV/c2) 1876.544 MeV / 0.42 MeV = 4468 x as much... @Mordred Neutrinos with higher (kinetic) energies are emitted in rarer situations (compare the amount of hydrogen and helium with all other elements).

I don't think so. It is not immediately rewarding project, so you invest a lot and then have (hypothetically) hundred or thousands years to get a return from an investment, so not interesting from commercial POV for a human being living here and now.. just like fusion.. Put thousands of satellites around the Earth that deliver Internet to customers, and they will pay every month for Internet (have you seen how much Elon demands? I paid less in 7 years than he wants in a month ). Put thousands of satellites around the Sun (or around the Earth) that deliver power to spacecrafts and/or Earth and how do you get a return on investment? This energy would be most optimally used to build even larger facilities in space, instead of delivering it to Earth. In capitalism, everything revolves around money. If you have money, you fly to the Moon or Mars. If you don't have money (but you have knowledge and know-how), you don't fly to the Moon or Mars. Silly. In fusion, one does not know when it will 'click' and 'the light at the end of the tunnel' will appear.. For eventual investor, with energy from the Sun delivered to satellites around it, it would be easier to estimate when they will pay off, than from nuclear fusion.

..it has already gone through the fusion and supernova explosion stages at a distant time > ~ 4.5 billion years ago.... It's just debris/dust from supernovae et al.

The same can be said for putting solar panels around the sun and harvesting all the energy from it ("dyson sphere").. ps. For dimreepr to create a Dyson sphere would be an even bigger waste of money..

I don't see any description of the device in your post. You need to be more clear/descriptive.. Do you have any idea what kind of nuclear reaction occurs during fusion? i.e., what fuel is used, what is the power output, what is the energy released, etc.?

It is not a "rubbish device." It is used to keep an aircraft in flight in rare situations with overweight, oversized and over-powered engines. Which malfunctions under rare conditions in which pilots must take control of the entire aircraft. But they were not taught about the existence of this device, so they could not react properly at the crucial moment, so people died. They had just a few seconds to figure out what is happening, and act accordingly. The autopilot takes data from sensors. Just like a human. If the sensor malfunctions, and the weather is bad, such as nighttime, with no external light sources such as stars, sun, city lights, the understanding of the situation (position, altitude, aircraft rotation) is disrupted, both for the human and the computer. Hence the disasters. Pulling back the stick when you don't have lift is a recipe for disaster. You need the correct data from sensors or daylight to know if you have no lift force. Many disasters have happened simply because pilots thought "pulling back the stick" was a good idea in their situation. Understanding the situation is most important. Therefore, sensor redundancy to be able to determine which sensor is malfunctioning. One sensor may be malfunctioning, two sensors give different results, one gives bad results and the other gives good results, which one is correct? Three sensors, one is defective, two are unlikely to.. at the same time (unless they share the same wires/computers, etc.).

This is what you are wasting..

If you are addicted to TeX maker, you can simply use VirtualBox with a version of Windows that worked well with it. This way, I run Windows only apps on my Linux machine. Update, downgrade, figure out. It seems to be still supported, open-source, and cross-platform app.. Such an application shouldn't have any problems with Windows security and firewall, as it doesn't need any such actions to do its job. Did you download it from the authors' site and not from a third party website?
