/sci/ - Science & Math

Hey /b/, I'm pretty fucked.

I recently start playing some retard, small ass chat game, in my country.

When I discovered that you could purchase VIP, I just found some cards online, and attempted to use them. I managed to purchase for 2 times 30 dollars.

But everytime I attempted to be behind a proxy, it disconnected me. So I had to do it on my own IP a couple of times.

When I was on the chat earlier, I got banned for cheating with the credit card. And the case was given to the police..

tl; What do I do, to clear this shitty school laptop I'm on - and clear my router/switch - so they can't find out where I am?

Hey guys, I'm using this as a last resort. This question was on an earlier homework, and I was never able to figure it out. I hate to ask here, but I haven't had any luck. I have a test tomorrow and just need a little help.

Construct an NFA recognizing the language given by (011 U 101 U 1).

What if their language was more like a computer language OP, where the fundamental principle was sort of on/off,
In the same way you mentioned the idea of object/thing, non object/thing.

sup /sci/,

I have a test today on binary operations, everything seems simple enough with addition, multiplication and division, however when I have to subtract without changing the number to be subtracted to a twos compliment, I run into issues.

I understand the borrowing technique, and it is easy enough when there is a one to borrow on the immediate column to the left, however, I am really unclear on the mechanics when you have to borrow from a further place to the left, what happens to all the numbers inbetween?

for example, 10001- 11, so its 1 - 1 first, easy, 0; then its 0-1, so you have to borrow, but what happens to all these zeroes inbetween? do I just ignore them and take the one from the very left and make the zero im working with 10 (2) ? i have a feeling this is way wrong... any help?

Hello /sci/ first time using this, and wanted to ask a question about binary numbers. My teacher last year had taught the class a 'simple' binary. (Where A = 1, B = 2 etc.). Then I looked online and found that A = 65, (source: http://www.roubaixinteractive.com/PlayGround/Binary_Conversion/The_Characters.asp).).
Now I was wondering how do you calculate the binary number, as you divide the 'number' by 2, but when you get to 1/2 -> 0/2 would the '0' always be added to the end, or does it stop when reaching the '0' and exclude it from the binary number.
Would really like some information on this.

Computer Science question here. How can I achieve a result of 1111111100000000111111110000000011111111000000001111111100000000 from 10101010 using the least of operations. Basically I want the byte number to be expanded into a Int64 number in such a way that I can explicitly extract 8 byte sized peaces that either have a value of 255 or 0.

Where does /sci/ find legitimate and free online IQ test at?

how to learn assembly

sup /sci/ I'm currently considering what I want to do at uni. I have stripped my coices down to comp sci or comp sci with artificial intelligence. I'm currently studying computing, maths (and english lit. AS) and german at A level. any advice you can give would be appreciated.

TL;DR: wanna study comp sci, any advice?

Theoretically, everything in the universe can be broken down into ones and zeroes. If a person were able to find an exact cipher for human behavior, then nothing would be off limits. A combination of words could be used to get anything from anyone. Simply knowing the correct algorithm could make you a god. If you see a cute girl from across the room, you walk up and use what's basically a code, and she's yours. That big muscley boyfriend of hers? Another combination of words, and he pays you to take his girl out. It's all ones and zeroes. Observe behavior, do the math, get anything.

But how? Where do we begin? What's the first step in breaking the god code?

alright /sci/,

I'm taking a computer architecture course right meow and we're working with bitwise logic. Our assignment is a series of bitwise logic puzzles where we're given a limited number of operators and operations we can perform in order to achieve a certain goal. It's stuff like isNotEqual, or bitWiseOr. I've gotten all of my answers through guess and check, but the harder puzzles are really starting to frustrate me.

Right now, I'm stuck on isLessOrEqual. It looks like this:

isLessOrEqual(int x, int y).
Ex. isLessOrEqual(4, 5) = 1
Ex. isLessOrEqual(9, 8) = 0

we're allowed to use 6 operations total, and we can use the operators:
~ ! ^ & | + << >>

Can anyone help?

How many of the integers between 1000 and 9999 contain exactly two ones?

I've decided of the many programming languages to learn and become adept in C++.

Could /sci/ be kind enough as to show me some useful links to get started learning. And also what compiling software I should be downloading.

So I've known this girl for many years and just recently I started talking to her over facebook. We have both shown interest in each other but she sent me this weird message. The subject line was in binary and I have no idea why she would send me something like that. In the body she said "you should send me a picture id love to see your face :)". Also the binary numbers were "110010101101011100011101. I used a binary translator I found on google to convert the numbers because I thought it might be her phone number. I was able to come up with 202 215 29 and I thought it might be her phone number but it is missing 2 digits. What I know is she lives in Seattle. Are there any other possible solutions or possibly linked to her phone number?

Just got my first uC programmer (Pickit3).
I was thinking, "hey, I've programmed before -- piece of cake".
Of course...I've never tried assembly before..........

WHAT THE FUCK IS WITH ALL THIS BINARY SHIIIIIIIT?!?!?!?!

Fuck!

By the time I can do this fast, the Pickit3 will be $10 cheaper.

Somewhat confused - Group theory

Let S be a set with two elements.
How many different binary operations * can you define on S?

When it says "different binary operations" what does this mean

does this mean +,-,x,/,etc because I am sure you can define a binary operation to be anything you want and therefore giving an infinite number of different binary operations? For example a*b=n times a+n times b where n=1,2,3,4,5....inf would all be different binary operations. Because I'm sure I just miscomprehended the question.

How strong of a computer would we need to reproduce the universe, all its particles, complying to all the laws of physics.

Mathfag here. I'm leaning toward applied, so I feel like I should know more programming. If I was living in the Matrix I would download the following to my brain. Since I can't do that, which one one should I take up for independent study?

R, C++, Matlab, Mathematica, Python

Also, did a moderate amount of VBA in a previous job so I can skip the basic flowchart command business.

hey /sci/

does anyone know an easy way to think about complementary number systems (2s complement, 1s complement, etc)

alright sci, i'll be honest, i need to know this for some homework. but my reasoning to know this is not so that i can circumvent homework, but just so i can do it more easily

alright, so I know its easy to convert binary whole numbers into octal and hex. But how would you guys go about converting fractional binary numbers?

I can't see any other way than simply adding up the fraction and trying to represent it in the other number system

tl;dr
convert fractional binary to octal and hex

hello anon can somebody of u explain me the binary language like what number is what letter and how the grammar works etc. cuz me and my buddy want a secret language like we talk binary in college and everybody goes like "wtf?" lol
