    What is front-line research in computer science and mathematics like?

    Posted: 15 Oct 2018 10:18 PM PDT

    I am simply a 2nd year undergrad studying computer science and was wondering if anyone here has had experience in research of leading problems and topics within computer science and mathematics as well as explain what it took to get there and what it is like?

    A super-simple function maximizer (with cool graphs)

    There is a foundation structure that is permanently stable, has complete privacy and/or shared space too, no ownership, and has infinitely unique and complex traits. What do you do with it?

    I'm not a great writer but I find writing helps simplify and quiet my thoughts. I don't know how else to ask about this than a story.

    Imagine you are going to build on the moon, but want to be very very accurate with where you build.

    You decide to scan the moon and re-create it digitally so you can choose the best spot and build at leisure.

    Some kid puts on his VR goggles back home and sees your digital moon scan. He's walking on the moon. He uses his digital paintbrush and draws a dickbutt before leaving. You're pissed.

    You tell your friend and he says the moon isn't big enough the two of you to build without interrupting eachother. You tell him its the biggest digital structure ever created and he laughs at you.

    He says he'll copy that moon and put it inside something larger where nobody will ever bother you.

    "how will I find it?"

    "coordinates"

    "What TF are you talking about? So you scaled up the virtual editor size and make the moon small?"

    "Nope. I hid it."

    "Where?"

    "Inside the computer."

    "Inside the computer?"

    "Yes, inside. I used something bigger than the moon that already exists and put it there."

    "How will I find it?"

    "coordinates."

    "seriously?"

    "you're going to want them..."

    "won't someone just find it?"

    "Not if you hide it."

    "How can I hide something in a digital structure? It either exists or it doesn't."

    "Exactly, so I found something that exists already."

    "A digital structure?"

    "yes."

    "bigger than my moon..?"

    "Your moon is pathetic, aim for the stars."

    "Bullshit, show me."

    "Alright. Put these VR goggles on and give me 4 numbers(almost this simple, better to find a spot first..)"

    "Re: -457/250

    Im: 0

    Width: 1/4

    Height: 1/4"

    "Your number choices are weird, but lets put them in the coordinate box and see where we are"

    "What the fuck is this?"

    "You're looking at a true 3D space on a 2D monitor. What do you expect?"

    "But the moon..."

    "The moon isn't here yet, this is just a location for the moon. Forget the shapes and lines you see, they're so far away you can't imagine."

    "Alright, but what is this?"

    "This is an ancient monster created by anything that repeats itself enough times(until deemed infinite) or becomes 0. It has no spacial limits, and it will always be here."

    "Give me an example.."

    "So your mom had a mom and her mom had a mom and on and on.. However, you're definitely not going to have kids. You're a 0. If you had kids and they had kids, and it branched out from there, it will be deemed infinite after enough iterations. That's a 1, and its as real as you or me. Just not touchable."

    "Every iteration(repeat) adds more detail, from our perspective it would be like coming from space looking at a coastline. It gives more and more detail depending on how close you are to it until a coastline appears and there are beaches or water. Its exactly like that, but imagine each moment an iteration. Iteration resembles time in this sense, the same way you resemble your father and the lineage before him. Its just moving through time, but digital time is malleable."

    "This gives us the 3rd coordinate to use in a 3D digital manner. It is absolutely unique. You have to process exactly 0 of the rest of the fractal to know that your coordinates exist. It is entirely private, infinitely large and will last longer than the universe."

    "What will you do with it?"

    "I'm going to fill it with my moons and make you call them stars you idiot."

    How does VirtualBox work?

    Posted: 15 Oct 2018 10:39 AM PDT

    I'm taking OS in college and it's a lot of fun. I'm trying to wrap my head around how VirtualBox/VMware works. I understand that the Virtual OS itself is a program that gets loaded by the host OS. But is there the notion of a kernel in a VM? Where do sycalls get handled? Is all hope lost for cache optimization? Do interrupts come from the host OS, or from the VM, or both?

    Thanks!
