  • I enjoyed the depth of this answer. That being said…

    4 copies seems like a level of paranoia that is not practical for the average consumer.

    3 is what I use, and I consider that an already more advanced use case.

    2 is probably most practical for the average person.

    Why do I say this? The cost of the backup solution needs to be less than the value of the data itself x the effort to recover the incrementally missing data x the value of your time x the chance of failure.

    In my experience, very few people have data that is so valuable that they need such a very thorough backup solution. Honestly, a 2$ thumb drive can contain most of the data the average user would actually miss and can’t easily find again scouring online.






  • While you are not wrong about these different specialities within the trade, there can still be an effect. Let me illustrate:

    Suppose you like bananas but not apples. One day there is an apple disease that kills most of the apple trees leading to a collapse of the apple market. You feel relieved because you don’t eat bananas anyways. But you go to the supermarket and find that not only are the apple shelves empty, the banana shelves are empty too! Why? Well people still gotta eat, and not everyone is as picky as you, they switched to bananas and now the banana market is under supplied too. And it’s not like you can build a banana farm overnight.

    Back to electricians, if the salaries of data center electricians increases rapidly, you will find that those electricians who are qualified for both (even if it is just a very small number) might focus on data centres, straining the supply of residential electricians. Just like with banana orchards, it takes time for new electricians to enter the market, and those new hires will further be swayed to the data center specialty first, further straining the residential market.

    We can see a real example of this with the price of RAM. RAM manufacturers saw increased demand for data centre RAM so they switched focus to that market and it ended up drying out the consumer side supply, hence the surge in price. And just as with banana plantations and electricians, you can’t start up a RAM fab overnight.




  • Okay, but I don’t think the scenario you are describing is particularly relevant to the comic. This looks like a white collar job application, not a blood diamond mine or sweatshop.

    So back to the point at hand. The question is, why do you want to work here? It’s a super relevant question. If all that was important to you is money, you’d go work on an oil rig. But most people don’t do that. Thousands of intangible factors someone might choose a workplace besides just for cash. Work/life balance. Personal interest. Comfortable work environment. Relevant experience. Proximity to home. Perks…

    The point of the question or interviews in general is to stand out from other applicants. The answer “I need cash” doesn’t make you stand out.





  • The earth’s core is about 5500C and is mostly composed of iron and nickel, probably. Presumably, it would shrink tremendously going from 5500C to 0C so in theory you could calculate the rate of shrinkage using iron’s rate of thermal expansion. However the core is also under immense pressure which makes iron much denser (smaller) than on the surface of the earth. The immense temperature and pressure is a result of the action of gravity pulling the core onto itself.

    The short answer I think is the earth cannot exist as we know it at anything below its core temp of 5500. Suppose we waved a magical wand that set it’s temperature to 0, it would implode on itself (along with the rest of the planet) and heat right back up to its current core temp of 5500 before you could measure the effects of thermal expansion.





  • You crave salt and fat because your body needs a little bit of these things to survive, but finding salt and fat out in nature is really really hard, so those cavemen that liked the taste of salty or fatty foods enough to make the extra effort to find those foods were more likely to survive to be your ancestors and you inherited that behaviour. That’s why you like McDonald’s, it’s full of the salt and fat that is hard to obtain if your diet consists of mostly roots and mushrooms and leaves.

    McDonalds is bad for you because it’s unnaturally full of salt and fat. Far, far more than your body needs and far more than your cavemen ancestors would have eaten naturally. Especially if you eat McDonald’s often. Too much of anything turns that thing into a poison.

    McDonald’s has only been around a generation or two. That’s not enough time for the people who crave McDonalds and eat too much of it to die off, leaving mostly people who don’t crave McDonalds to remain.
