There are special sprays that protect against water and dirt, but they should be used immediately after buying shoes or washing them: https://www.google.com/search?q=Water+Repellent+and+Dirt+Protection+Spray

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..

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..

Reread it again. Dune is a sci-fi.. So we will have recursion.. https://en.wikipedia.org/wiki/Recursion_(computer_science) (this can lead to stack overflow )

.. 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.

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)

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.

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.

Programmers, especially in the past, use lookup tables (LUTs), to speed up an extensive mathematical algorithm. In the '80 years, in CPUs without multiplication implemented in hardware, LUTs were even used for multiplication and division. Multiplying 8 bits by 8 bits requires 65536 16-bit LUTs = 128 KB (which can be in ROM!) https://en.wikipedia.org/wiki/Lookup_table "An n-bit LUT can encode any n-input Boolean function by storing the truth table of the function in the LUT. This is an efficient way of encoding Boolean logic functions, and LUTs with 4-6 bits of input are in fact the key component of modern field-programmable gate arrays (FPGAs) which provide reconfigurable hardware logic capabilities." Example in C/C++: uint16_t multiply_lut[ 65536 ]; // Initiated by the user once at startup. uint16_t multiply( uint8_t src1, uint8_t src2 ) { uint16_t result = multiply_lut[ (uint16_t) ( src1 << 8 ) | src2 ]; return( result ); }

The diode passes current in one direction and does not pass it in the other direction. This is the case only in theory. There is a voltage that causes the diode to let current through in the opposite direction. But a Zener diode is designed to let current through sharply at a well-defined threshold voltage. As a result, too high a voltage does not reach (in theory) the parts protected by the Zener diode. Zener diodes are often used in pairs: When you have element at hand, or on circuit, you should check its specification and charts like: ..and read Wikipedia about it for general information.. ps. Not without a reason people invented RTFM. https://www.google.com/search?q=RTFM

..finally we have explanation of many things.. thank you so much for sharing this with us..

Actually your post makes no logical sense to me. I can see the errors in the source code, so I can predict that sooner or later it will crash and under what circumstances (cumbersome for others to foresee, especially the "children of the debugger"). Telling another programmer that he/she made a mistake in line X is unethical? If I tell "fix this or people will die because airplane or spacecraft will crash", somebody will tell "right" and simply ignore my advice, I foresaw this disaster and this happened. If programmers/engineers will fix it, then can tell "you foresaw nothing, as nothing happened, see? There was nothing to worry about!".. People say so about the Y2K problem (although a spaceship was destroyed by a similar mistake!), and so now they say about COVID-19.. ("they scared us for nothing!")

Number six: get out of the house so the whole premise can't happen. Number seven: you shoot yourself before two hours, so the whole premise can't happen. There's a (forty year old) movie about it, but instead of a "being of superior knowledge" it's just a gypsy fairy.... https://www.imdb.com/title/tt0074251/ "Modest editor, has shipped his wife and kids for the weekend, and is trying to relax in his house at the outskirts of Warsaw. His quiet evening is only disturbed by the accidental forecast made by a Gypsy woman, that at evening time he will murder a mysterious brunet. He is trying to escape the destiny, but to no avail" (it is a satirical comedy, you would love it)

People are slaves. Slaves of money, most of them, except some homeless and some billionaires etc. And slaves to tradition, rituals, the religion they were raised in, addictions, etc. How can you say you have free will if you can't even wake up when you want? The clock rings at 5, 6 or 7.. and you rush to work, which you hate..

STM (from the article that you just linked) is not one of them.. ..then you would not build an electron microscope, but a tunneling microscope.. It's a completely different technology, with different operating principles.. ..what is your definition of an electron microscope.. ? "An electron microscope is a microscope that uses a beam of electrons as a source of illumination. They use electron optics that are analogous to the glass lenses of an optical light microscope to control the electron beam, for instance focusing them to produce magnified images or electron diffraction patterns. As the wavelength of an electron can be up to 100,000 times smaller than that of visible light, electron microscopes have a much higher resolution of about 0.1 nm, which compares to about 200 nm for light microscopes." STM is not listed on the list of electron microscopes, and they clearly stated: don't confuse with STM: https://en.wikipedia.org/wiki/Electron_microscope ps. Personally, I would prefer to build an SEM. ps2. A good starting point would be to create a 3D printer or 2D printer/plotter with high motion resolution (so that the electron gun remains stable and the sample moves slightly below).

https://en.wikipedia.org/wiki/Scanning_tunneling_microscope "Not to be confused with scanning electron microscope (SEM)." https://en.wikipedia.org/wiki/Scanning_electron_microscope "Not to be confused with Scanning tunneling microscope." STM != SEM..

Some people have been on the forum (any forum) too long and too bored with the forum and answering (newbie) people, they become unbearable and a cumbersome to the rest.. unable to answer any simple question.. We have seen this in the past.. Some of them were banned because they were too disruptive.. I'd call it professional forumer burnout.. It's very simple. When you accelerate an electron with a well-known voltage, it hits something. Their kinetic energy ranges from zero to that voltage, expressed in eV (e.g., 5,000 V will get you from 0 to 5,000 eV K.E.) If it has high enough energy, it causes the electron to be ejected. When an electron is attracted to an atom or molecule, it must emit a photon. We have 1) electrons that have been ejected and 2) photons that were emitted by electrons attracted to an atom or molecule. Ejected electrons and/or photons can be captured by sensors. Reflected electrons can be captured by sensors. Their energy (kinetic energy) (thus velocity), angle and time of flight from the primary emitter to the object and then to the sensor can be measured. A computer algorithm reproduces this in the computer's memory and displays it on the screen. Don't be silly. Electron microscopes are damn expensive and this is not a project you can do at home. At least not you.. Making an electron gun requires a fairly good vacuum. https://en.wikipedia.org/wiki/Electron_gun The number of calculations here is in the billions, so your little knowledge of Python is not enough to create a program. You need C/C++.

Hello! They were sending them to jail! And then - do what you want - at least here.. If I send you to a space station on the moon or Mars and then release you, you will be in the same situation as they were 200 years ago....

Are you praying for a reboot?

In the Concentric Universe. but parallel means that there is independent variable with the same x,y,z,t.. How does it fit into your "Concentric Universe" theory.. ?

Unfortunately, you did not pay enough attention to the discussion.. As big as something is, the discussion of volume.. When I was asking about the mass.. ps. Phi apparently not for everyone.. In which parallel Universe?

How does the TARDIS bag summarize the weight contained in the bag? (volume vs mass problem) If this is really a reasonable question, you should start by creating an algorithm, e.g. by searching out Internet what the weight (and the volume) of the animal is, what percentage is bone, fur, head and other dispensable parts. The real meat is then dried (i.e. even further reduction of mass, i.e. water in it). https://www.google.com/search?q=drying+salt+meat https://www.google.com/search?q=dried+meat "To dry cure meat with salt, cover it entirely in salt for a full day. In order to make sure the meat is completely covered, fill a container with salt, place the meat on top, and pour more salt over until it's buried." https://www.google.com/search?q=cured+meat+weight+loss "The meat should lose 35-40% of its weight by the end of the process, and the only way to tell when the meat is finished curing is to weigh it." The weight of human bones is 14%. (Measure the weight of the jumbuck by yourself, before and after) So, if we assume a similar bone mass, out of a 50 kg animal - 50x14% = 43 kg x 60% (due to drying) = 26 kg. The head and fur go off first, as do the internal organs (they would go bad first). At least 50% of mass, and even more volume, is gone. https://www.google.com/search?q=lowland+sheep+lamb "The animals' body weights were monitored from birth to day 180, when they were slaughtered. At slaughter, the lambs reached an average body weight of 38.82 kg. The percentage of slaughtered parts, slaughter yield and the proportion of cutouts in the half-carcass were tabulated."

..unlikely.. HTTP/HTTPS web archivers work only with true HTTP/HTTPS servers.. but Facebook and Twitter are dynamically generated JavaScript servers. They change stuff depending who is watching it, and (try to) ignore bots.. i.e. archiver will get nothing.. Some (devs) says "use WebAPI".. Have you seen the "prove you're human" requests (created by Google!) where you have to click something in the right order...? Web archiver won't work with that - and it won't archive pages.. Entire FB, Twitter are "blank pages" for automatic archivers.. ps. I have created HTTP/HTTPS search crawlers. (like "Google").. Google demands data from you, to index pages, and at the same time, dismiss giving you their data.. The result will be equivalent to "dark ages" like three thousands years ago in the Greece.. https://en.wikipedia.org/wiki/Greek_Dark_Ages They even want to speed up the collapse by automatically deleting data due to user inactivity. Two or more years without logging into an account and deleting the account. The days when "Google is cool" passed about twenty years ago..
