  • I think it is safe to say that OP’s question was lay speak for “what is the mean time to get to a result”. Other than that I don’t think you actually addressed the question.

    Let me try to get it started:

    Randomly generating music might be akin to password cracking. Cracking short or simple passwords can be very fast, while cracking long or complex passwords can be very long. The rate of password guessing also affects the time to get a result.

    To calculate an answer, we need the following information:

    • Guessing speed (how fast is each “song” generated and checked?)
    • Minimum “song” length that needs to be generated
    • Complexity of “song”: how many instruments (“voices”), resolution (are whole notes only ok, or do we need. Half or quarter notes?)
    • Settle on some subjective definition of “song”. Is S.O.S. in morse code a “song”

    You might be able to take a genre of music, and decompose the songs within to get some answers… I don’t have the time for that. Anyone want to take a stab at estimating the calculation?













  • 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.
