Is it possible to log my action in Windows?
If you don't mind an application with a GUI, there is an application written by Microsoft engineers FileMon: https://learn.microsoft.com/en-us/sysinternals/downloads/filemon Later replaced by ProcessMon: https://learn.microsoft.com/en-us/sysinternals/downloads/procmon Such an application installed on your computer can tell you if someone has used your computer without your permission or if someone has hacked into your computer, even if anti-virus applications find nothing. I don't think it's interesting to monitor file activity to spy on someone (unlike keyboard presses and mouse movements). It is an anti-spyware application, not a spyware application....

Is it possible to log my action in Windows?
Of course. You can always write it yourself. Then it will meet all the tight requirements. Source code on MSDN: https://learn.microsoft.com/en-us/dotnet/api/system.io.filesystemwatcher?view=net-8.0 This type of operation is widely used by legitimate applications to monitor changes in configuration files. When you open a text file in editor X and editor Y, and save in one of them, you click another, and it complains that the file needs to be reloaded, this is due to the use of this API..

Will the sun rise tomorrow?
No. The Sun does not rise. That's a premature, childish version of ancient people who didn't understand how the world works. The Earth rotates, causing the illusion that "the Sun rises" and "the Sun sets", when in fact it emits light all the time, just to a different part of the Earth.. Hydrogen fuel burnout.. ..do people know about the future when they prepare supplies for the winter.. ? (In Africa, Central and South America, and the Islands, they don't do that.. year-round fresh fruits and vegetables).

Why is there so much pain and suffering in the world?
..which will lead to an increase in food prices.. and poor people will have even more trouble buying them than they do now.. In 2022, after the attack on Ukraine, grain prices rose due to the blockade of Ukrainian exports (which is/was a significant global market participant in several areas, such as sunflower oil, 42% of global market share in 2019. It was the oil I used most often, every day before the war. Approximately 1L per month. Its price has doubled). Farmers were "uberhappy".. When everything "calmed down," prices fell to almost "normal" pre-war prices and.. farmers began to complain, go on strike, etc. etc. What is a PITA for some (customers) is heaven for others (farmers, sellers, stock market investors, investment banks playing on commodity exchanges).. Capitalism.

Why is there so much pain and suffering in the world?
...sometimes highly educated and rich people lose touch with the reality that is the reality of most of the rest 8 billions.. ..soon (with growing population and side effects of global warming) you can have a completely new level of "war for resources" e.g. for a fresh clean water.. ..only those who will pay.. This is how capitalism works.. "We"? Who is "we"? Rich Westerners? 70% of Americans who have $1000 or less savings? 1) construction industry is significant industry in the world. The less developed the country, the higher the percentage of GDP. 2) agricultural industry is significant industry in the world. The less developed the country, the higher the percentage of GDP. 3) The whole reason they have problems with shelter, food and water is because they have no money to buy them.. This is how capitalism works..

Why is there so much pain and suffering in the world?
Meat or plants are a source of food, i.e. a source of stored energy created by autotrophs. Humans can become autotrophs through genetic manipulation of DNA or technology (CO2+H2O+N2+little others-> organic matter) and stop killing other animals and plants to survive. Overpopulation will force such solutions sooner or later..

Seeking Clarification on VAT Calculation
AFAIK, companies only receive the gross amount, not the net. Even if the b2b catalogs have a net amount. If you receive 200 EUR gross, with 25% VAT, your company has a net 200/1.25 = 160 EUR income, and 200-160 = 40 EUR VAT it will have to send to the government. When a company creates a product catalog, it does the opposite, i.e. 160 EUR net x 1.25 = 200 EUR gross or 200 EUR net x 1.25 = 250 EUR gross. In reality, it is a bit more complicated. A company sells something with VAT to its customers/companies, and has to pay other companies for something (the ingredients to make the product) also with VAT. Sometimes these VAT taxes are different, e.g. food has a low VAT, but a finished meal in a restaurant is taxed differently than the ingredients. Only the difference is sent to the government. The company that sold the ingredients/components also has to pay VAT, but at a different rate. The company that sells the ingredients/components does not know whether the buyer is a retailer or another company and whether it is a VAT taxpayer or not (company can opt-in or opt-out in some industries to some level of income)

Sales Tax Pyramid Scheme
When you buy something for $106 gross, $100 is the net amount and $6 is the tax amount. Then, from this $100, the seller must subtract CIT ("corporate income tax") https://en.wikipedia.org/wiki/Corporate_tax , the rest must be used to purchase goods in the warehouse or to production, employee salaries and other bills.

Colour
"Color" is a poor human perception of the wavelengths of visible light. When you look at the color "yellow" on an LCD, LED, CRT, smartphone screen, it is simply a mixture of red and green light at maximum values. A human perceives it as the color "yellow". But there is no yellow wavelength there at all! Some screens have three LEDs: red, green and blue. They form pulses. If the end of the pulse is at the beginning of the pulse, it is equivalent to a continuous signal, and we have the light of a given wavelength (R, G and B) on all the time. If the pulse on time is equal to the pulse off time, it is half bright, and so on. Everything else is created in the human brain. All the gray scales, all the intermediate colors. It is simply in the brain. It is called PWM (Pulse-Width Modulation): https://en.wikipedia.org/wiki/Pulse-width_modulation You create it with 0, 1, on time and off time signals.

certificate error today at SFN
@TheVat SFN is certified by Let's Encrypt, so it's free. But you can configure it to renew automatically or manually. If it is configured automatically the script receives too much data about the server it is installed (admin privileges, ability to alter Apache server configuration etc.). It can be used to hack the server and/or install a backdoor. Commercial pro SSL is quite expensive. More expensive than a domain. More expensive than a VPS..

What are the Main Causes for Skin Rashes?
In India, Pakistan and Bangladesh, it's the dirty water in the Indus and Ganges. People flush leftovers from toilets without sewage treatment plants into it, and then other people (poor majority) wash their clothes in it, bathe in it, drink it, wash their plates, etc. etc. I would not use their water even to flush the toilet..

Do you clean or wash your cheap sneakers?
I used to often put my sport shoes in the washing machine.. One, two or three months of daily use per wash. Depends on how often they are dirty.. Depends on where you live..

Online Java Compiler Issue: Code Not Executing as Expected
.. try using different Java online compiler.. ? I tried this: https://www.programiz.com/java-programming/online-compiler/ And it showed: java -cp /tmp/gCdTYn4aQ5 Main 5 66 But this 66 is simply a lack of EOL.... After changing the code to: System.out.println(""+fruit.length()); all is fine.. java -cp /tmp/gCdTYn4aQ5 Main 5 6 6 ps. Report the problem to the developers who created the online compiler, along with a code snippet, and it will be fixed.

Would you pay for an App that was a very specific AI bot?
This is a science forum, not a science fiction forum. This is the kind of question you should ask in the Dune forum.. Scientists would be more interested in applications that help them in science subjects such as physics, chemistry, mathematics, computer science, etc. However, entertainment apps can be distributed to anyone, science apps are only of interest to scientists. So the potential user base (8 billions+) is much higher for entertainment than for science. It's easier to reach them and easier to sell them if making money is the main driver of your activity on the subject. ps. creating such AI/chatbot should be pretty easy - you just give the all books to read by it, and the all subscripts from the movies.. A weekend job, I would say.. There are six originals made by Frank (I have them all offline), as well as quite a few made by his son and third parties. https://en.wikipedia.org/wiki/Dune_(franchise)

How diode add voltage
Booster circuit. A diode prevents current flow in the opposite direction. The coil stores energy and then releases it on demand. Switch is whatever you want. Usually an electronic clock, which gives pulses on and off. ..in a less layman's version, temperature, pressure, air cleanness and humidity will be taken into account.. etc. A resistor has a certain capacitance and inductance, A capacitor has a certain resistance and inductance, A coil has a certain resistance and capacitance.. They are small, but not none.

How diode add voltage
Where have you seen such a phenomenon? Show us the circuit, maybe you misunderstood something. General simplification for the layman: 1) A resistor limits the current through the wire. It can be used as voltage divider. 2) A capacitor stores electrons on plates for later use. 3) A coil stores energy in magnetic field for later use. 4) A diode blocks current in one direction. If the current exceeds the limits ("specifications") of the components, the component is unable to dissipate the energy fast enough and sooner or later fails. It is a function of current, voltage (and therefore power, P=I x U) and time (and therefore energy, E= I x U x t = P x t ). There are graphs that show how long a component can withstand an overcurrent or overvoltage. Any element can fail, if its specs are overly and lengthy exceeded. Failure symptoms: 1) A defective resistor will usually be 0 ohms, i.e. it will no longer pass current. That is, it limits the current to zero through its wire. 2) A defective capacitor does not store any electrons anymore. 3) A defective coil usually passes no current. i.e. it does not store any energy anymore. 4) A defective diode usually does not pass current, i.e. it limits in both directions, instead of only in one. The energy entering the wire is equal to the energy leaving the wire minus what was consumed by the elements and dissipated as heat. The number of electrons must be equal (unless you have some kind of device that ejects them into space). One of your the previous threads was about smps. It is the coil that stores energy and causes the voltage to rise, not the diode. Since the coil has stored energy, and part of the circuit is intentionally turned off, it must release stored energy. And it does so in a very short time. The number of electrons is constant, so the only thing that can be increased is the voltage (Q=I x t, E=Q x U = I x U x t). There is a voltage spike, which is later smoothed by capacitors. Although in typical domestic applications, smps usually generate lower voltage than the input AC voltage. Lower voltage, such as 5 V, 12 V, 24 V, but with higher current than the input voltage of 230 V or 110 V.
