Speeches... this is the only thing politicians are good at.... Did you hear the V.P. speech to the child in Kaliningrad on Sept. 1.. ? ...politicians, especially in the US, do not write their speeches.. they have a team behind them that does.. they are simply.. speakers.. If you read Shakespeare aloud, that doesn't make you Shakespeare..

Methanol has a different boiling point (~ 64.7 °C) than ethanol (~ 78.23 °C), so when you distill a mixture of the two, methanol goes first. When I distilled ~ 500 mL of mash, the first 5-10 mL of product was collected and treated as "trash" (burned later as fuel, so don't throw it away, it can still be used). You should have equipment with a thermometer:

Yet to be written.. after the event..

Thanks for sharing. Very useful. +1

Miners, steelworkers and shipbuilders are not well paid in your country? Here they are well above average.. ..you cut your statement to the level it is not understandable.. In a truly free market, when you don't like your job because the pay doesn't meet your requirements, you find a new one you like.

It's a never-ending loop. People see increased prices in stores. They go on strike. They get raises. And business owners have to raise the prices of goods in order to have money for the workers, who are paid better. And the cycle repeats itself. People see prices rise and again want more money.. Strikes caused the collapse of communist/socialist countries. The only employer was the government. Striking miners, influenced steelworkers, influenced shipbuilders etc... and vice versa in all possible combinations When the shipyard workers went on strike, the communist politicians turned off all telephony and all possible communications, so they were unable to notify the miners and steelworkers about the event. Then, when communism collapsed, all these people lose job. Funny. They were not needed in such quantity like in communist country which hired people just to give people any job so they are not boring (therefor inefficiency of communistic country). In capitalistic country, the most important thing is efficiency, otherwise there is no income, and business has to be shutdown. If the government owns everything, then companies that draw energy/money from ordinary taxpayers can survive for centuries, half a century.. The company instead of making money is a black hole for taxpayers' money.. The strikers are 1) stupid or 2) pretend not to see how the price of what they build and sell changes over time. e.g. the price of coal on the stock exchanges. At the same time, the miners 1) do not want to reduce the workforce 2) do not want to reduce wages.. This is "mission impossible"! This results in the inefficiency of the entire mine. That is, they lose money than they earn. Coal mines hire people when the price of coal is high so they can produce more. Then comes the cycle of falling prices on the stock markets. But the workers don't want to be laid off, and a thriving company has a downfall.. ...go to your boss and ask for a 10% pay cut when it will make it easier for a failing company to survive.. If someone is not a slave, they can resign if/when the contract does not meet their requirements.. No? Computer programmers quit their jobs every two to three years. HR are in queue.. Owners of a business in a capitalist country 1) invested their own money to start the business 2) borrowed money from banks 3) borrowed money from 3rd party people e.g. investors who want to get them back.. The standard of living is given only once and then it can't be lowered? I guess in the U.S. the easiest way to go bankrupt.. looking at the number of homeless people on the streets.. "A person with money" (aka "investor") can 1) make a new business and start having problems like strikes at his/her company or 2) put that money in the bank 3) buy liquid stocks 4) buy government bonds, what will he/she choose?

But what do you mean by "bad business owner"? "good business owner" just delivered what the market wanted.. What will the "bad business owner" deliver in return?

..then there is gap which you can try to fill.. ...sorry.. I am printing, 3D printing, my own... as unique as Mona Lisa, Salvator Mundi etc. one copy in the entire Universe.. If you have a spare 1B, I can send one to you. Great investment opportunity for such a mortal! How many times have you had something unique in the entire Universe?

I didn't expect questions "how to kill someobody" on this site either.. Wow.. Don't torture prior death? That's so merciful from your side.. ..I don't believe you wrote such things..

Seriously, you wanted to reveal to the world, that you are murderer.. ? Thank you for your honest confession. Thankfully priest won't be needed anymore.. People honestly reveals their sins to the world on the Internet forums nowadays. Cool! Go to queue, after putin and his bastards, etc.. ..like Jews if you don't give them enough food.. Want to know what I do with flies? I open a window..

..then make a dress with pockets if there is an unmet demand for it and become a billionaire.. ? Business owners try to find 'gaps' which they can fill by what people always wanted and/or they never even dreamed about.. A good business owner asks customers what they want. This is done at fashion shows to gauge whether something will be criticized or welcomed. ps. "pocket"/"bag" is older than the dress.. had to carry stuff almost naked..

The phrase "The market always decides" means a battle between supply and demand. If people are buying dresses without pockets then apparently there is a demand for them. Huge corporations make unique things, or try to make unique things, to have monopoly. Also, patents and licenses reduce the chance of competition. In the past, e.g. hammer were made by craftsman, now hammers have a brand printed or engraved on them. And some people (snobs?) buy stuff based on brand recognition. They're not just looking for a hammer, they're looking for a hammer with a specific brand, meaning no substitutes.

Do you want to know what I think? The future of home is solar roof tiles.. https://www.google.com/search?q=solar+roof+tiles i.e. the entire area of roof is one huge solar panel seamlessly merged with roof..

Speed is distance in meters divided by time in seconds. So it does apply to time curve f(t')=t.. If time at some point, goes faster or slower, then you need another clock, which will tell how much they differ, when they try to synchronize their clocks once again after re-meeting.

..perhaps he is thinking of cutting the surface into infinitely small areas and combining them into one circle and dividing into four parts.. ..wordplay.. He did not say how many cuts can be made..

That's asking a lot, as I said. ...computer programs, utility programs, solve problems if they are not just for entertainment....

Making basic ray-tracer in C/C++ is ~ 1-2 hours project, especially if you will stick to parametric objects like spheres, boxes, planes, therefor objections of teachers about it is too easy for a final degree student project. Do you have experience in OpenGL? Learn especially glDrawPixels() https://docs.microsoft.com/en-us/windows/win32/opengl/gldrawpixels as you will presumably want to use it to output the temporary and final rendering buffer to the screen. From ray-tracing routines: KD-Tree to optimize geometry (if you use some real geometry, not parametric one, which is "too easy to bother" - if you have no parametric objects you have to write I/O loader of some object format like .obj (which is also pretty easy text file, but will take a couple of hours to do it correctly, due to its caveats) - therefor you need/should to partition data to limit the amount of ray-intersection routines to minimum, to not execute it multi-million times per pixel) https://en.wikipedia.org/wiki/K-d_tree eventually Octree: https://en.wikipedia.org/wiki/Octree https://www.google.com/search?q=how+to+find+intersection+of+line+and+plane (instead of plane use also keywords "sphere", "triangle", etc.) Then to shading: https://en.wikipedia.org/wiki/Phong_shading Other algorithms you have in references. https://en.wikipedia.org/wiki/List_of_common_shading_algorithms Not really. OP wanted to make ray-tracer, not teacher. Not really. Making ray-tracer as homework for one or a couple evenings is typical in IT. Yet another ray-tracer.. It would make sense to make yet another ray-tracer, if you would utilize GPU (CUDA/OpenCL) to do it, instead of CPU, or at least give an option to use GPU apart from the CPU. Split to multi-threads is a must have, I think, otherwise your code will run at 1/12 or more of potential of your CPU.. In the easiest implementation, one thread works on Y number of lines at a time. y=screen_height/max_thread_count.. In more challenging, each thread dynamically allocates lines or regions on the screen, which requires some multi-thread communication and synchronization, or thought and experience.

My router can be connected to USB to the computer and it works perfectly fine. USB v2.0 has a maximum of 5 V and 1 A, which gives a maximum output power 5 W. But this router draws 1.6 watts. A traditional 100-watt light bulb has 60 times more power than the router. Just to give you idea how little it is. The RF power emitted by the router is literally a fraction of that 1.6 watts, counted in mW (milliwatts).. Additionally it fades with distance..

This is the story of the people who passed through the "Russian infiltration camps". Original: "Російські фільтраційні табори. Українці розповідають про принизливі огляди, допити та хабарі З початку повномасштабної війни росія розгорнула систему так званих фільтраційних таборів. Через них доводиться проходити всім українцям, які хочуть виїхати на території, підконтрольні Україні. Важко повірити, яких принижень зазнають люди, щоб вирватися на волю. Ми поспілкувалися з ними й дізналися про все з перших вуст. Українці, які були в російських фільтраційних таборах на окупованих територіях, розповідають, що вони пережили там. 17-річна Марія Вдовиченко жила в Маріуполі. В один із днів квартира її сім’ї згоріла від прямого влучання російського снаряда. Тоді вона з батьком вирішила виїхати з міста. "Ми взяли найнеобхідніше й вирушили в дорогу на своїй автівці. Навколо тривали бої, але в нас була мета: вибратися з цього пекла", — розповідає дівчина. На одному з блокпостів їх скерували до селища Мангуш — для проходження фільтрації. Там були величезні черги, люди днями перебували без їжі та води. Окупанти максимально все затягували. І так було не тільки тут, а й в інших "таборах". Фільтраційні табори росії: допитують навіть про книги і хобі "Дійшло до того, що ми стояли в черзі на автобус, яким проїдемо 200 метрів до нової черги, — каже 39-річна Наталія Кальна, яка також із сім’єю намагалась виїхати з Маріуполя і котру скерували на фільтрацію у селище Нікольське. — Щодня нам потрібно було приходити о 9-й ранку й чекати, чи буде хоч якесь просування. Для нас це все тривало майже півтора місяця!" Сім’ї Наталії довелося заплатити окупантові 100 доларів, аби пришвидшити потрапляння на... допит. Цю процедуру проходять усі, кому більше як 16 років. Жінка розповідає: на допит викликали по одному. Питали про професію, ставлення до української влади, росіян, війни і навіть про книги та хобі. Обов’язково вивчали мобільні телефони. "Я залишила на гаджеті трохи нейтральних фото, а батько повністю почистив усе, — ділиться Марія Вдовиченко. — Це викликало в окупантів підозру... Тата лупцювали, морально тиснули, погрожували покалічити та вбити. Коли ж зрозуміли, що це не дає результату, на прощання сильно вдарили по голові. Оговтався він уже на вулиці. Під знущальні вигуки росіян ледве дістався нашої автівки..." Другий етап фільтрації: беруть відбитки пальців і не тільки Після допиту українців відправляють на другий етап фільтрації — внесення даних у єдину базу росії. Для цього беруть відбитки пальців, руки та долоні, а також роблять фото. Лише опісля видають папірець, який дає дозвіл на виїзд. Проте отримати той "документ" щастить не всім. "Пам’ятаю, як при нас виводили людей, які не пройшли фільтрацію, — зазначає Наталія. — Їх саджали в якісь автобуси й везли у невідомому напрямку..." Тож можна сказати, що нашим співрозмовникам перепустка на волю далася малою кров’ю. На відміну від 25-річного волонтера Ігоря Талалая, який евакуйовував людей із Маріуполя. Його схопили на одному з блокпостів. "Я був взутий у черевики, це не сподобалося "деенерівцям", — каже харків’янин. — Так само, як і патріотичні світлини в моєму телефоні. Цього виявилось достатньо, щоб позбавити мене волі". Ігор потрапив до рук окупантів 19 березня, а на волі опинився аж 15 червня. Спочатку він майже три тижні просидів за гратами у відділку поліції в окупованому Мангуші (у камері, розрахованій на 5 — 6 людей, було 32!), потім — у Докучаєвську. "Нас не просто утримували, а й проводили постійні допити, били та морально тиснули, — пригадує чоловік. — Росіяни хотіли вибити з мене зізнання у тому, що я якось пов’язаний із військовими. Коли ж заперечував це, звинувачували в брехні". За якийсь час Ігоря Талалая перевезли в колонію у сумнозвісній Оленівці. Умови там були не кращі: двоповерхова будівля без санвузла, в якій дуже тхнуло. Люди спали на старих матрацах чи просто на бетоні. Їсти давали, але порції були настільки малі, що навіть не втамовували голод. Як пережити фільтрацію? "Допомагає віра" Людей, з якими харків’янин перебував у колонії, також утримували безпідставно. "Наприклад, там був чоловік, якого кинули за грати за татуювання герба України, — ділиться співрозмовник. — Також із нами утримували пастора: духовна освіта, здобута у Львові, була для росіян вагомою причиною, аби позбавити волі його із сином, а їхнє майно забрати". Ігор еві пощастило вибратися з полону. Допомогло те, що долею чоловіка опікувалися міжнародні гуманітарні організації. Після пережитого йому таки виписали довідку про проходження фільтрації... "Увесь той жах нам допомогла пережити віра, що Бог не дає на долю людини випробування, які вона не може витримати, — підсумовує Марія Вдовиченко. — Ну й бажання вижити: на зло окупантові, який робить усе, щоб нас знищити". Віталій МІКУЛА" Google translated version: "Russian filtration camps. Ukrainians talk about humiliating examinations, interrogations and bribes Since the beginning of the full-scale war, Russia has deployed a system of so-called filtration camps. All Ukrainians who want to leave the territories controlled by Ukraine have to go through them. It's hard to believe the humiliations people go through to break free. We talked to them and learned about everything firsthand. Ukrainians who were in Russian infiltration camps in the occupied territories tell what they experienced there. 17-year-old Maria Vdovichenko lived in Mariupol. One day, her family's apartment burned down as a result of a direct hit by a Russian shell. Then she and her father decided to leave the city. "We took the most necessary things and set off in our car. Fighting was going on all around, but we had a goal: to get out of this hell," says the girl. At one of the checkpoints, they were directed to the village of Mangush - to undergo filtration. There were huge queues, people were without food and water for days. The occupiers delayed everything as much as possible. And so it was not only here, but also in other "camps". Filtering camps of Russia: even books and hobbies are interrogated "It got to the point that we were standing in line for a bus that would take us 200 meters to the next line," says 39-year-old Nataliya Kalna, who also tried to leave Mariupol with her family and was directed to the village of Nikolske for filtering. "Every day we had to come in at 9 in the morning and wait to see if there was any progress. It took us almost a month and a half!" Natalya's family had to pay the occupier 100 dollars to speed up getting to... interrogation. This procedure is carried out by everyone who is over 16 years old. The woman says: they called one by one for questioning. They asked about the profession, the attitude towards the Ukrainian authorities, the Russians, the war, and even about books and hobbies. Mobile phones were definitely studied. "I left some neutral photos on the gadget, and my father completely cleaned everything," says Maria Vdovichenko. in farewell, they hit him hard on the head. He recovered already on the street. Under the mocking shouts of the Russian, he barely reached our car..." The second stage of filtering: they take fingerprints and more After interrogation, the Ukrainians are sent to the second stage of filtering — entering data into a unified Russian database. For this, fingerprints, hands and palms are taken, and a photo is taken. Only after that, they issue a paper that gives permission to leave. However, not everyone is lucky enough to receive that "document". "I remember how people who didn't pass the screening were taken out with us," notes Nataliya. "They were put on some buses and taken to an unknown destination..." So we can say that our interlocutors were given a free pass with little blood. In contrast to the 25-year-old volunteer Igor Talalay, who evacuated people from Mariupol. He was caught at one of the checkpoints. "I was wearing boots, the Deener people didn't like that," says the Kharkiv native. "Just like the patriotic photos in my phone. This was enough to deprive me of my freedom." Igor fell into the hands of the occupiers on March 19, and was released on June 15. First, he spent almost three weeks behind bars at the police station in occupied Mangush (there were 32 in a cell designed for 5-6 people!), then in Dokuchaevsk. "We were not just detained, but also constantly interrogated, beaten and morally pressured," the man recalls. "The Russians wanted to force a confession out of me that I was somehow connected with the military. When I denied it, they accused me of lying." After some time, Ihor Talalai was transferred to the colony in the infamous Olenivka. The conditions there were no better: a two-story building without a bathroom, which smelled very bad. People slept on old mattresses or simply on concrete. They gave me food, but the portions were so small that they did not even satisfy my hunger. How to survive filtering? "Faith helps" The people with whom the Kharkiv resident was in the colony were also detained without reason. "For example, there was a man who was thrown behind bars for tattooing the coat of arms of Ukraine," the interlocutor shares. take". Igor was lucky to get out of captivity. It helped that the man's fate was taken care of by international humanitarian organizations. After what he experienced, he was issued a certificate of passing the filtration... "We were helped to survive all that horror by the belief that God does not give man trials that he cannot withstand," concludes Maria Vdovichenko. Vitaly Mikula"

@studiot due to your thread I spend over an one hour watching tutorials "how to make cheese at home".. there are even companies selling what we need (which is basically a "microbial starter kit" and "microbial rennet enzyme", the rest of the equipment I can print on a 3D printer, just have to reverse-engineer them). From 10 L of milk we can get 1 kg of cheese, and some more ricotta cheese.

You must be snobs.. I stopped buying "normal" cheese (e.g. Gouda, Emmentaler, Radamer etc.) (and cured meats too) when they went from $5.1/kg ($2.3/lb) to $7.7/kg ($3.5/lb) this year, as it is too high.. Instead, I prefer to buy more chuck steak for $4.7/kg ($2.1/lb), cheaper and more nutritive.. 1 kg potatoes, onion, and there is food for entire day for ~$3/day. Today will have also special soup soured (fermented rye starter) for $0.5/plate. And thinking about starting making such sour soup by myself to limit costs. Sourdough for sour soup: ps. Anyone here have a cow to borrow? We can also make some experimental cheese..
