iPhone and Apple do the same thing, and even a thousand times more, and yet you don't mind buying and supporting them every year... ;) If you can control an IoT device by voice, it must have its speaker turned on non-stop to detect that you are talking to it. The same applies to phones that have a voice-controlled assistant. So if you agree to send debugging data (you have such a clause during Windows installation, for example), you also agree to send your voice if it is needed. Every computer and device has a unique serial number, and computers have several or a dozen such serial numbers for different parts. Each of them can be used to identify someone. You don't know who stole your phone, the police don't know and don't care who stole your phone, but Google knows who stole your phone... ;) as soon as they try to create a new Google account or log into an existing account (even after resetting the data on the phone) (without it Google Play Store won't work).. If someone is “synchronizing data” between two devices because they bought a new phone, how do you imagine this process? It could be sending everything from phone A to the cloud, and then from the cloud to phone B. So you gave all your sex tapes and nudes and all the secrets of your life to Apple/Google... The most dangerous thing is that if these devices need to download/upload data from the Internet, you give them access to your internal LAN, which in most cases means your Wi-Fi password. This is 100 times more controversial than the fact that this little robot drives around your carpet and knows the square footage of your room. Hiding the fact that someone is viewing your Wi-Fi password would be child's play under the guise of IoT device debugging data. BTW, I heard that one of the most famous cybersecurity here experts got hacked. He revealed it himself to show how easy it is to do. Fortunately for him, the hacker was a pentester and told him himself that he had screwed up. The guy made a website using AI, some kind of “AI Cursor.” 18k+ lines of code generated. Web hosting project. The AI set up the Apache server itself. People told him that directory listing had been forgotten to be disabled, and what were the consequences? Someone (pentester) discovered that one of the directories was .git. And it had the entire source code of the entire website project. The pentester downloaded 2700+ files from this project. He read and analyzed the source code. And he created his own 70 GB VPS, just like that, with access to all the server's databases.

I mainly drink beer. I only drink vodka when someone buys me a drink. I can't even remember when I last bought vodka, it must have been around 2015-2016 on New Year's Eve. And I make drinks with vodka anyway. We had a situation here in the country this year where supermarket security detained a relatively young man and took him to the office where they waited for the police, and he opened the vodka he had stolen (0.7L) and drank it in one gulp. And he died. When the police arrived to give him a ticket for ~$140 for theft, they performed CPR on him.

..now you know why Russians drink so much vodka... ;)

You have depression. It's a chemical reaction. It could be caused by reversible or irreversible factors in the past, or these factors are still in your environment. Irreversible factors, like the death of a loved one or the death of a child, are difficult to come to terms with. Reversible factors are within your control. People who only talk and listen, those you say you don't want to pay, only force you to analyze yourself while confessing on their couch. If you're intelligent, you can conduct such an analysis yourself, and for free. To heal the brain damaged by prolonged depression, you can use pharmacology (i.e., chemicals; but they are usually either illegal or prescription (which you won't get because they didn't prescribe it to you) ) or just food. Very good results are achieved after eating very spicy food (Carolina Reaper style). Eat spicy food for breakfast, lunch, and dinner. For months. This causes a positive reaction in the brain. Positive thinking allows you to reprogram yourself. Start by changing your place of residence, changing jobs, etc. This will eliminate environmental factors. And a breath of fresh air in your life. Go on trips/excursions, to other countries, to warm countries, explore the mountains and surround yourself with beautiful places where you can say “how beautiful it is here”... Going to a job you hate when you've depression is a pretty bad idea. It only deepens depression. Chemicals such as alcohol, marijuana (it also depends on the variety of the plant, but that's a topic for a completely different story), etc. are also a bad idea - they are depressants. The goal is right - to suppress negative emotions to the point of flying away - but it won't have lasting effects. You prefer to get such advice for free from online people you don't know and have never seen. Right. That makes sense... ;)

I don't think that in the near future it will be able to detect the examples you gave. Detecting seat belts when someone is wearing black clothes and/or has tinted windows? That's not very realistic. *) Detecting children or dogs in the back seat?! The rear seats are not visible at all to such cameras. Detecting license plates is difficult enough in itself. The faster someone is driving, the more blurred the image is. At 70 km/h, a vehicle travels 19.4 meters in one second. At 30/60 fps, this gives ~ 65 cm/frame and ~ 32 cm/frame, respectively. Your phone has a sports mode that allows you to take better quality photos by shortening the exposure time. But this, in turn, means that nighttime, cloudy, and rainy conditions will be recorded less well. This sport mode only reduces blurring, it does not eliminate it completely. It registers fewer photons. In order not to lose quality, it must be took in good lighting (lots of photons). *) ChatGPT calculated that 1 pixel of a 4K camera (3840 x 2160 pixels) corresponds to 3 cm when the camera is 100 m away from the car. I think the whole process will look completely different. AI will analyze the car at point A (first camera) and look for it at point B (another camera). The distance between A and B is constant and known, so we just divide by the number of seconds and check if it exceeds the average. So, for example, our 19.4 m/s for 70 km/h limit. If so, it will search for that car on the exits from highway, comparing only the appearance of the vehicles. And there, at low speed, it will get a clear image of the license plates. Human assistance will still be needed to check if plates were good enough and cars were not mixed. Detecting someone who is speeding (or riding with someone who is speeding) can be done by analyzing the login logs to GSM network base stations. If someone does this regularly, they will often be at the very top of such a database, so all you have to do is wait for them to drive off the highway. You shouldn't go overboard with enforcement here. Sometimes speeding up and exceeding the limit is necessary to avoid an accident. ps. Now imagine how absurd this is: cameras to catch drivers and give them tickets are everywhere, people have them in their cars, especially in Western countries, but planes don't have video recorders to capture what pilots are doing, even though the lives of hundreds of passengers depend on their mistakes.. When pilots report an emergency, all data from their cockpit could be sent to headquarters in real time, and a whole team of people could analyze it even before the crash. Depending on the type of fault, this drop from 10 km to 0 can last up to 15-20 minutes after engine failure.

Since you mention biology, you might be interested in a water pump and/or solenoid valve for turning on watering. You can also combine this with a water moisture detection module so that your Arduino project waters the plants on its own. Soldering , preheater, hot air gun, all with temperature control in one piece: Cost $250 (preheater small size, so not good for mobos except mobile)

To desolder and repair, you will also need items such as 1L of IPA, distilled water (to clean dirt and/or flooded laptops) - it must be evaporated well - use IPA + hot air for this, ear sticks. But these are negligible costs. A desoldering hot air gun can be stand-alone or built into a soldering iron. The cheapest stand-alone model I've seen costs 8 USD (when it is good device you can control temperature with potentiometer and LED screen) If you don't intend to repair electronics professionally, there's no point in overpaying for fancy soldering stations. You'll use it once in a blue moon (i.e., never). Electronic boards may have internal tracks that are hidden. multi-layer boards. Such boards are extremely difficult and/or impossible to repair, and in most cases, it ends up being a waste of time. How can the internal layers be damaged? Water from flooding, warping of the board due to uneven heating (because you don't have a preheater, which is quite expensive equipment (entire computer/laptop mobo must fit in it), and you used a regular hot air gun from a soldering iron or a stand-alone device), or an electronic component explosion and charring underneath it due to high temperature (caused by high current flow and/or excessive voltage). Charring allows current to pass with high resistance in random places that are completely unintended for this, what damages other elements. As a beginner, you are unlikely to encounter such hardcore problems, and if you see such a hole in the board, you will probably just throw it on the pile of potential components to be used in other repairs. To perform CPU/GPU repairs, you must have a BGA resoldering kit with balls and nets, various sizes of balls and nets. They are sold in sets containing, for example, 25,000 balls, so once you buy them, you probably won't use them up in your lifetime. But these are already “serious repairs”.. This requires a microscope and a hot air to melt these balls. If you make a mistake and they stick together, or if one is missing, the CPU will burn out. Processors are not resistant to hot air that has no temperature control. The simplest project on Arduino is simply turning the built-in LED on and off. If you connect a digital pin to a 120/240V relay, you can control a serious electrical device such as a light bulb or motor. If you buy a slightly more expensive Arduino clone that has built-in WiFi (I see them for $7 here), in the fraction of time I spent writing this post, you can make your own HTTP server on that WiFi. There is a library for this. A few lines of code are enough. You can access such a server via your cell phone and remotely control lights and/or motors and/or TV and/or refrigerator, etc. Here is a simple example of flashing a light bulb with Arduino: To complete this project, you do not need 95% of the items I mentioned above; just an Arduino, a relay, and male-female quick connectors will suffice. You don't even need a soldering iron here. To control the motor speed, instead of using a digital pin, you can use an analog pin and a transistor and a separate power from the external power supply (devices up to 5W can be connected directly to the Arduino). Arduino has a power supply input. However, it only accepts 5V. 12V+ is not recommended. This may not be enough for the motors. Or you would have to tinker with some step-up/boost-up modules to convert 5V to 12V or 24V which will be enough for a more powerful motor.

An electronics technician needs: a multimeter, a soldering iron (preferably with adjustable temperature, but these are more expensive), a solder sucker, a set of screwdrivers of various types, miniature tweezers (such as those used for plucking nose hair), and an antistatic mat may also be useful. If you intend to repair phones, there are special mats with designated places to put screws, which will prevent them from getting lost. e.g.: Their prices are so low that if I were you, I would immediately order one for repairing phones and one normal large one. A cell phone repair kit would also be useful—they are very cheap. Around $5 for Android and $5 for iPhone. If you also have a 3D printer or a more expensive soldering iron with a built-in hot tip, then you have everything you need to repair a damaged phone screen. (The filament 3D printer has an adjustable printing surface temperature. https://en.wikipedia.org/wiki/Fused_filament_fabrication The cheapest FFF/FDM 3d printer from Creality Ender-3 costs 250-300 USD) That's probably everything that's cheap and for everyone. More expensive items include adjustable power supplies, both voltage and current, which prevent exceeding the range. These devices can be purchased for between $50 and $200. Even more expensive items include microscopes for electronics engineers (although there are some imitation models available for less than $25—I have one, and it works fine, but it is slow rate at 640x480). An IR camera is very useful for checking which component is heating up the most, i.e., is likely to be damaged because unlimited current and/or excessive voltage is flowing through The cheapest IR cameras cost around $300-400 and connect to cell phones via USB. I've seen some junk for less than $100, but they have a resolution of around 32 pixels or something like that, so it's better to go for higher resolution. An oscilloscope is a useful but expensive tool. $100-$500. However, it can be simulated using Arduino and a voltage divider and/or an opto element that will buffer between the circuit and Arduino. An oscilloscope will allow you to see what current and/or voltage is flowing through a given circuit over time. This way, you can find out whether the computer is booting and at which stage it fails. More expensive laboratory power supplies have their own current/voltage consumption graph on a time chart. The repair procedure for any electronic device is as follows: connect a laboratory power supply to the device, point an IR camera at it, and start increasing the voltage and current from 0V/0A (remember to zero it prior connecting!), watching which components heat up. You reach the voltage that it gets from the power supply at the factory (search the net/read etiquette). You see if it draws current, and you adjust it along with the voltage. If it's a simple fault, the damaged component usually lights up on the IR camera. Then you start analyzing whether it exceeds its parameters and why this may be happening. A typical component that breaks down is an electrolytic capacitor that has worn out and whose parameters have changed, causing it to no longer meet the basic design specifications. Sometimes you can even see which components have burned out and literally exploded. This often happens with capacitors, for example, and sometimes with resistors and chips (they then have a hole in their casing). If the CPU or another chip is damaged, you will still have a problem finding a replacement. Often, you have to buy other devices, the same model, and transplant them, cannibalize them. Chips can be non-programmable or programmable. To repair a programmable chip, you not only have to re-solder it, but also copy and extract data from the old broken one. Various readers are used for this purpose. That's a different story and a different level of difficulty. To properly replace such a chip or CPU on a computer or laptop motherboard, a so-called preheater is useful. If you intend to solder a lot of cables, you may also consider purchasing a soldering pot. Their prices vary depending on their tin capacity and power. If you don't intend to repair but design electronic circuits, you will need breadboards and cables for them (male-male, male-female, and female-female), as well as quick connectors for breadboards. Cheap. $5 for a large breadboard. A set of cables for them probably costs $5-10. Arduino is a must-have. Raspberry Pi optional. You don't need starter-kit - it is a waste of money. You don't need original - clone is good and cheap too. $10 for Arduino-clone is fine price. I hope this is enough to get you started on your adventure with repairing and/or building electronics. Your wallet is your limit.. ;)

KingKobra, from your arguments, it seems that you are giving science some human-like attributes.. Which is basically absurd (but very typical for humanists).. Now the absurdity of your argument has been further reinforced by your ignorance of mathematics. If we take the number of people who die in current wars, terrorist attacks, disasters, whatever, and divide it by the total population, we get a tiny percentage. It is the mass media (and the speed they share some unverified information) that blow these tiny numbers up to gigantic proportions because that is how they make money. And if we compare this to what happened a thousand or two thousand years ago, the loss of 100,000 people today vs. 100,000 people 2,000 years ago (with a world population several dozen times smaller) looks completely different. How can we talk to humanists? Go learn some math! Science has nothing to do with the problems you are talking about. So how could this indicate the limits of science? Which science discipline? Humanities or real science? Science is not a living entity, and it should not be endowed with any humanistic, fantastical attributes.

I know that. It must be forum software bug, because I quoted Patch Cabbage, not you.. I don't know which part of my post was grumpy. Was it when I wrote “This is nonsense” to summarize his post.. ? I copied and pasted his post into ChatGPT (without suggesting my answer), just in case I had made a mistake in the translation, and it agreed with me that the post didn't make sense. For example, ChatGPT: "CRT televisions rely on careful HV safety design. That modification could have been extremely dangerous, even if it “worked”. " (about replacing transformer by resistor+diode).. "The person is expressing real safety concerns, but much of their reasoning is incorrect or based on misunderstandings." "Their message reflects anxiety, personal anecdotal experience, and some misconceptions—not an accurate technical assessment." OK. I will try..

You can use a 250 V-rated capacitor in a 25 V circuit, as long as the capacitance value is correct. The voltage rating just indicates the maximum voltage the capacitor can safely handle. Sometimes manufacturers use components with higher voltage ratings simply because they had them in stock and/or they were cheaper. It doesn’t mean the design is ‘dangerous’. This is not a rule. BTW, to rectify 230/240 VAC, capacitors rated at 400 V (!) are used, not 250 V. So you're wrong anyway..

What a load of nonsense.. A mains-powered supply - whether switching or transformer-based - always has the same dangerous high voltage on the input side. The difference is in efficiency and design, not in the presence of high voltage. The real difference between a linear and a switching power supply is not the presence of high voltage, but the operating frequency and the way energy is transferred. Both are mains-powered and both have dangerous primary-side voltage. SMPS just use high-frequency conversion to make the transformer smaller and more efficient. Well, that's just total nonsense. A transformer changes the AC voltage to a higher or lower one, while a resistor and a diode only cause a current limitation, rectify the sine wave to pulses, and still leave the voltage unchanged. The pulse frequency before and after remained the same.

It's physically impossible. You're holding the jar in your left hand, so your hand is holding it from behind, and your right hand is holding the screwdriver. You can't hurt either wrist. Insert a screwdriver (only a flathead/minus type) into the gap between the jar and the lid, and gently turn it clockwise until you hear the hiss of air entering the jar. It's just a millimeter to the right. Once the pressure has equalized, you can unscrew the cap. There's no hocus pocus involved. You don't need to be a nuclear physicist to know how to open a jar. I open beer bottles like this every day.

All you needed was a screwdriver.. quick and easy.. pry off the lid and let air in, and once the pressure is equalized, you can unscrew it without any problems. That's a bad idea because you'll ruin the lid. You're right here. Jars are easier to open if you put a cloth on them first.

They have “a million chips” (seriously, not quite) because modern power supplies are usually “switching power supplies”.. https://en.wikipedia.org/wiki/Switched-mode_power_supply They are more efficient (lose less energy) than traditional power supplies (from your sketches) with a transformer. They generate less heat. They are smaller. They are cheaper to manufacture (contain less copper). They use MOSFETs (on your sketches there are NPN/PNP).

No one here steams them. Put them in water and boil for over an hour (don't peel). Then wait for them to cool down, peel after cooking, and grate them. Next, fry them in a pan with oil, with onions, also grated. Season with salt and pepper. This is called fried beets. It is used with Viennese schnitzel with a potato puree.

So that it's difficult to understand what it's really about? ;) It is difficult to come up with something innovative. One innovation is a development of an innovation from years ago, which is a development of an innovation from hundreds of years ago, etc. Innovative, it is a flying chair (magnetic? drones?) with a built-in toilet for waste disposal.. ;) I did not suggest what you are suggesting. The use of a translator is obvious because it makes mistakes that are easy to spot, which ordinary people do not use in their speech ("dear colleagues", this is not what I meant - translators put quotation marks with an internal comma or period, e.g. “blah,” whereas someone writing it by hand would write “blah", ).

Any glass jar will do, with metal lid, because you can make a hole in it, and then use a glue gun (available at electronics stores) to attach it to the lid permanently, sterilely, and hermetically. https://www.google.com/search?q=glue+gun+ebay Today I made 2 liters of beetroot sourdough starter. 500 g beetroot 4 cloves of garlic 350 ml lukewarm water large bay leaf 6 peppercorns 4 allspice berries teaspoon of salt Peel the beets, cut them into cubes to make them easier to put into the jar. Add spices and water. Wait 7-10 days. After drinking the first portion (e.g., 1/2 - 2/3 of the juice), you can add water to the rest and repeat. I usually add onions too, but today I'll try the procedure without them. If you want to do the above, I will give you the procedure for making soup from it in a week, once you tell me you have the sourdough starter. It's a question of whether you have red beets at all.

Philosophy, not to mention that it is abstract, has never been able to do the things you are talking about.. This shows that you don't understand this saying at all.. the water molecules have moved, so it won't be the same river, but a different one, with different contents.. “Untangling Gordian knots” does not mean cutting them, unless it is a play on words. Someone could just as well knock over the chessboard and say, “I won this game of chess.”.. The Gordian knots remain tied.

It's just a matter of purpose (aim/goal in AI/LLM world). Before they build that bridge, they have to get around by boat.. The only questions are: 1) how, 2) how much will it cost, and 3) will it ever pay for itself? Some say that the goals in the current LLM are poorly set, which is why they make statements (hallucinate) when they don't know something. If someone plays a game where you live or die, you will choose your answer without batting an eyelid. If someone can place a piece of wood across a river that is 2 meters wide so as not to get their feet wet (or if the tree fell down on its own due to old age), then they can imagine everything you are talking about right now. Don't go to extremes. Bridges were built long before the Romans. If you give a three-year-old child building blocks e.g. Lego, they will figure out how to build an arch bridge on their own. All they need are the blocks. Arkadiko Bridge (Greece) is from 1300-1200 B.C. (i.e. 400-500 years before Roma establishment).

Modern methods of creating AI/LLM involve designing a world in which this new creation learns everything on its own, i.e., there is no stage of imposing knowledge on it that is provided by humans during training. It has to go through this millions, billions of times to understand and remember what it can and cannot do, and how “physics” works in a given “world”. For example, we have an 8x8 chessboard and pieces, but we do not tell the AI/LLM what the possibilities are for each pieces. We only do f(x)=[giant number of parameters] which returns true or false. If it tries to move a piece to a place that the piece cannot move to, it immediately fails (return false) the entire game. From this, the AI/LLM deduces what possibilities each piece has. It learns “physics”. Later, through millions and billions of repetitions, it figures out how to play the game. *) If you create a function f(x,....) = (....) that returns true or false, and you start randomizing the parameters, eventually some combination may work.. You just need a very long time for randomization. You have four blocks in your DNA, and you arrange them in some order, e.g., random, and it either works or it doesn't. The creatures that survive are those that have the right combination of these random blocks in a given environment ( f(x,....) = true for them) *) https://en.wikipedia.org/wiki/AlphaZero

Using crap like the cloud to protect against DoS/DDoS attacks or bots results in such a website is not archived: https://web.archive.org/web/20250000000000*/rationalwiki.org At this point, we should have a complete backup of all posts: https://web.archive.org/web/20250000000000*/scienceforums.net It's total crap. Who in their right mind cares that there is no spam now, and in 20 years, not to mention hundreds of years, no one will know what we were talking about here? A day like any other. I had tens of thousands of hacker attacks on my servers every day.

I'm watching a video on YouTube with one of the most famous local physicists, and he said: I disagree with the first part, of course, but with the rest, absolutely... ;)

HTTP server can return any code they want. It could be a lie/fake. But suppose so it is true return code, we make things like these (you lucky *** I have this error at the moment): This means that rationalwiki.org is in an Akamai cloud. I don't have any servers in this cloud, so it's hard to say, but I can talk about similar situations in other clouds. Cloudflare has an option to act as a proxy server between its server and the real server that is set in the configuration (therefor the name "cache..."). Ping IP domain.xyz gives the cloud address, the cloud forwards this data to the real server, and it responds, and the data comes back. If possible, the data is cached so that the same data does not have to be sent to multiple users. "backed fetch failed" sounds like connecting to the original server that is proxied is impossible (from Akamai cloud server). People use cloud servers such as Cloudflare to hide the addresses of their real IP servers. scienceforums.net also uses Cloudflare to hide its real server IP. If hackers discover the real IP address of a server, they can attack it and prevent the cloud from connecting to it. It could also be an attack on Akamai (or some other cloud) that would have a similar effect. But there is no indication of this, because downdetector shows nothing. It also depends on what servers the real RationalWiki server uses, e.g., database. If it connects to other servers that are down or currently under attack, requests to it will fail, as they will e.g. timeout, and it will also be down from the user's point of view. I have a VPS that, after restarting the server (physical), does not start the Apache servers (application/service) it has on it. You have to start them manually. If Cloudflare acts as a proxy for it, you will have connection errors with that server (VPS). Some pages load (because some have been cached by cloud proxy service), but others do not..

It would be difficult to imagine a more grotesque text than the one above. Creating a conspiracy theory to explain an attack on a website that fights conspiracy theories. Simply chapeau bas..
