  1. What is the long term effect of wind energy on the planet? Is it really as sustainable as it is made out to be? We see videos about dams in china that supposedly slowed down the rotation of the earth. If wind power was to be scaled out what would the effect be? How sustainable are the parts used in wind farms. There are various articles about them winding up in landfills after a few years what are the challenges around recycling them and how many years do they need to operate to recoup the energy costs associated with building and recycling them?
  2. I think it is more a question of ethics here. Lets say a person makes a new type of vaccine. We know that the person has put a lot of work into developing the vaccine so we reward them with a patent for their contribution to cover the expense of the developing the product. This is in a lot of ways relatively fair. But when we allow AI to be an inventor there are other issues that arise. For example if I use AI to generate every possible version of vaccine that could ever exist then it unfairly eliminates competition from people. This is no different than a totalitarian regime having control over what you can do and would stifle further innovation from others that don't have access to this AI. I think cost is also a major factor to take into consideration. If it takes a lot of money for an AI to generate the new vaccine then it may necessitate awarding a patent to the company that created it otherwise there is no incentive to do so. But if the price is low then there will be an influx of frivolous patents.
  3. An NFA allows a Turing Machine to have transition from having n internal states to n + x internal states to any number of internal states. An input tape is accepted if any of the currently active internal states of the non-deterministic automaton result in an accepting state. A person doesn't have a finite number of cells in the body we can easily generate new cells to combat viruses etc. A DFA cannot create new internal states. It has a fixed number of internal states. It has been shown that there will always exist a theoretical DFA that can be constructed from an NFA with a known number of internal states. There is probably a scientific answer. One could argue that the body's ability to defend against infection qualifies as something non-deterministic that is probably not possible for a DFA. You could say that your body has learned to recognize a new tape called a virus. So we could assume that there are some things a DFA cannot do but we can't easily prove because it lies outside our understanding of science.
  4. It is possible, if we restrict ourselves to prime factorization we know that the distribution of primes is strictly increasing (if looking at the largest and second largest primes we know of the gap is fairly large). We can assume that after some point x the number of primes to test should be small enough to run in polynomial time using known algorithms. We just use a hashmap for the ones before that and we have an algorithm that has a polynomial runtime.
  5. You still use a mobile phone?? I survive perfectly fine with just a laptop. When would you ever need a phone now? You can't use one in the car unless it is handsfree and I would assume that car manufacturers will catch on to the fact that having built in internet for calls, voice recognition, etc. is a good idea. At home you have WIFI and smart devices like Alexa to answer the phone for you.
  6. They are hard to get a hold of over here and are usually over 1000 pounds. Twice the price of the gaming chair plus I am not sure if I am getting the value out of it. An office would make use of the adjustability of it for many people but I can get the gaming chair specific for my size?
  7. I want to buy a good chair as I spend most of the day sitting for work and had some pain in my arm because my current chair is just a wooden one from the kitchen. I have no idea what is a good chair to buy and there is so many brands I have never even heard of. The local furniture store has one that looks like this for 160. One person I know has a secret labs chair and he says it is very comfortable but they are very pricey so am not sure about it. Work uses IKEA chairs but am not sure whether I would be more comfortable in something that wasn't mesh. https://www.ikea.com/ie/en/p/jaervfjaellet-office-chair-gunnared-dark-grey-80363596/
  8. Did you not post on the forum about solidity before? Did you not study it back then and take notes so you can write it now? I feel like you are spending way too much time on something that would be a lot easier if you got a cheap course. I am not an expert in all this blockchain stuff. Surely there is one on Udemy etc but you will have to wait for a sale.
  9. Strange I didn't get any error when installing with python3 and pip. That is a CDN for downloading JavaScript to run web3 on a webpage. Similar to jQuery you just need to use the <script> tag. But it won't be available to Python or NodeJS.
  10. You should be using the latest ubuntu for a start as 18.04 is unsupported. NVM can be used to install the latest npm which will be able to install web3. curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash export NVM_DIR="$HOME/.nvm" [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" && \. "$NVM_DIR/bash_completion" nvm install node npm install -g web3
  11. We have limited idea of what the content of the videos will be. We had a previous example where we can easily count individual birds but would have difficulty counting a flock of birds with touching wings. The resolution of the images is very important if you need to distinguish specific things. To give a medical example you could have a slide under the microscope of patient blood. But if the cells are too clumped together it can be difficult for the computer to match the shapes of the cells against known illnesses.
  12. That is something I would not have thought to do. It was BuyItDirect that sold it to me. I asked them about it and they just fobbed it off as not their problem and to contact Samsung. Well that would be the last resort. The promotion https://www.samsung.com/uk/qled-tv-free-galaxy-z-flip-phone-package/ is over now so if I bought a new TV after returning it I still wouldn't get the phone.
  13. Who do I contact about consumer complaints in the UK. Samsung recently offered a free phone with my purchase but are refusing to give me the phone even though the terms and conditions said it was ok to order from Ireland and their staff reiterated that to me after purchasing the product they changed their tune to haha you aren't in the UK.
  14. Hello, the right data format would entirely depend on the data that is being collected.
