Possibly if the motherboard was badly made. Like crosstalk where a large voltage induces current in a nearby wire connected to the power on switch.

Are you sure you aren't being hacked?? Was the computer bought from a legitimate store??

So what it is a 50 50 chance. A chimpanzee could correctly predict it 50% of the time. What? Last I checked the CIA was run by Americans and not aliens. Why?

I followed basic algebraic rules z is a positive whole number multiple of 2. Y is more complicated it is a black box polynomial we don't know anything about since each polynomial will be specific to what number you put in. We do know however that it will follow basic algebra so we don't need to know anything about it.

Is it easier to see if I write it like this?? (3x+1)/2= x y(3x+1)/z = x 3yx - xz + y = 0 x(3y - z) + y = 0 x = -y/(3y-z) x = -10/(30-32)As you can see if x is positive it is a fraction and it will not increase forever. We know it won't increase forever for certain values because it is a group of linear equations.

Why not ask the school if the T180 would be ok?? https://www.amazon.com/Texas-Instruments-TI-80-Graphing-Calculator/dp/B000OMXVA0/ref=sr_1_1?ie=UTF8&qid=1486313191&sr=8-1&keywords=t180+graphing+calculator

We could expand the equation out but all that happens the numbers become worse recurring fractions or negative numbers never positive whole numbers for loops and we can assume that no numbers cause it to increase forever.

Okay. So for collatz to be false. We must satisfy a simple function and show looping. (3x+1)/2 =x (3x + 1) = 2x 3x - 2x + 1 = 0 We can solve for all looping in the colatz conjecture by introducing a new variable y which is a multiple of 2. 3x - yx + 1 = 0 All except for 2 loops are looping fractions. Therefore no real number exists that falsifies colatz

No it is isn't since all even numbers are divisible by 2. We just need to know what the last char is. <script> for(i=1;i<10;i=i+2){ if((i*3+1)%2!=0){ document.write("error"); } } </script> Do you see what I am getting at?? What matters is the frequency of division by 2. Division by 2 occurs more frequently and therefore every number must reduce to 1.

So I cleaned up the headers and now they match those sent by the Apache httpd as far as I can tell (apart from servername). //Sendfile.cpp #include "StdAfx.h" #include <Windows.h> #include "MimeHelper.h" #include <algorithm> #include <string> #include "time.h" #include <memory.h> #include "Sendfile.h" #include <stdlib.h> #include <iostream> #include <fstream> #include <tchar.h> #include <strsafe.h> #define LastModifiedBuffer 49 #define GMTLENGTH 37 int sendHeader(int socket, char *header) { char dest[3000]; const char* CRLF = "\r\n"; errno_t headerError; strcpy_s(dest, _countof(dest), header); headerError = strncat_s(dest, _countof(dest), CRLF, strlen(CRLF)); if (headerError) { printf("Error code: %d", (int)headerError); return 0; } header = (char*)dest; send(socket, header, strlen(header), 0); return 1; } int sendDateHeader(int socket) { SYSTEMTIME st; GetSystemTime(&st); char int_to_day[][7] = { { "Mon" },{ "Tue" },{ "Wed" }, { "Thu" },{ "Fri" },{ "Sat" }, { "Sun" } }; char int_to_month[][12] = { { "Jan" },{ "Feb" },{ "Mar" }, { "Apr" },{ "May" },{ "Jun" }, { "Jul" },{ "Aug" },{ "Sep" }, { "Oct" },{ "Nov" },{ "Dec" }, }; char GMT[GMTLENGTH]; sprintf_s(GMT, GMTLENGTH, "Date: %s, %d %s %02d %02d:%02d:%02d GMT", int_to_day[st.wDayOfWeek], st.wDay, int_to_month[st.wMonth], st.wYear, st.wHour, st.wMinute, st.wSecond); char* dateHeader = GMT; sendHeader(socket, GMT); return 1; } int sendContentLength(int socket, int length) { char *message, *contentlength, buffer[32], dest[3000]; errno_t errNum; sprintf_s(buffer, sizeof(buffer),"Content-Length: %d", length); contentlength = buffer; printf(contentlength); printf("\n");printf("\n"); sendHeader(socket, contentlength); return 1; } // GetLastWriteTime - Retrieves the last-write time and converts // the time to a string // // Return value - TRUE if successful, FALSE otherwise // hFile - Valid file handle // lpszString - Pointer to buffer to receive string #define LastModifiedBuffer 49 BOOL GetLastWriteTime(int socket, HANDLE hFile, LPTSTR lpszString, DWORD dwSize) { FILETIME ftCreate, ftAccess, ftWrite; SYSTEMTIME stUTC, stLocal; DWORD dwRet; char LastModified[LastModifiedBuffer]; // Retrieve the file times for the file. if (!GetFileTime(hFile, &ftCreate, &ftAccess, &ftWrite)) return FALSE; // Convert the last-write time to local time.

Wrong I try and test absolutely everything I use. Which takes longer than just reading the material.

Yes but it is good to learn. For instance if I wanted to make a game with payment processing then I have to know how to setup ssl sockets because most payment providers won't accept payment from insecure connections. Hewlett Packard has a tutorial on setting up an ssl socket http://h41379.www4.hpe.com/doc/83final/ba554_90007/ch04s03.html using the openSSL API but it is pointless following it until other stuff (like loading images) works properly. At the moment I want to make a code editor with syntax highlighting which will run a web server with https and open the page in google chrome when I click the run button. ps zip data is sent with a boundary given by a multipart/form-data post request. Like so not exactly sure how to receive that content in C though. -----------------------------25312170725491 Content-Disposition: form-data; name="test"; filename="ColorCode_1_0_2.zip" Content-Type: application/x-zip-compressed CRLF content -----------------------------25312170725491 What I am receiving at the moment looks like -----------------------------1137250621972 Content-Disposition: form-data; name="test"; filename="ColorCode_1_0_2.zip" Content-Type: application/x-zip-compressed PK in firefox so obviously the recv is cutting off halfway.

Yeah it should be a fun project. I know most of the protocols already. I learn by doing schools can be so frustrating like that who learns anything from reading books?? Not over http. Browsers encrypt with https. That's right https works on every port. However Browsers use 443. Oh and consts are variables kept in memory for faster runtimes on repetitive tasks. #define is not kept in memory.

It's a https web server i'm trying to make. So I want to use forms from HTML code.

#define is for macros. Why would I use it for a constant??

The Natural History Museum in London has an exhibit on quartz crystals and their use in silicon growth. Does anybody here know more about the process??

Well they can teach you pretty much anything did you read their page?? http://www.gold.ac.uk/ug/bsc-computer-science/ P5 https://p5js.org/ Html, Css, Javascript SQL Computer Architecture. AND OR NOT ALU System bus etc Java

I use the caps lock too for typing constants.

Alright I'm going to London tomorrow so I won't be able to work on this for a few days.

Okay so Seems to be working.

shutdown(socket,1) does the same thing. So I just need to add CRLF?? I dunno maybe there is a function on MSDN to generate it. The received header data doesn't have CRLF.

There is an error with mime types which cause errors to be thrown in the browser when I try to load an image or an external css stylesheet. I'm not sure how to set the headers properly.

Yeah I tried that too but it doesn't work 100% properly. The page only occasionally loads anything. //Reply to the client message = "<!DOCTYPE html><html lang='en'><head><link rel='stylesheet' href='css/test.css'/><title>test</title><meta charset='utf-8' /></head><body><div role='navigation' id='mySidenav' class='sidenav'><div id='split-bar'></div><nav id='navbar'><a>Home</a><a>Login</a><a>Register</a><a>Contact</a><a>Forgotten Password</a></nav></div></body></html>"; send(new_socket, message, strlen(message), 0); What I am sometimes getting back when I try to load the page in the browser. <html lang="en"><head><link href="css/test.css" rel="stylesheet"></head></html> So something is wrong somewhere. Maybe the formatting needs to be a certain way?? If it was totally wrong nothing at all would load. Hmm it appears to load in chrome but it is also continuously loading so maybe I need to close the connection to the client once the data is sent???? Edit: The following seems to work ok in microsoft edge. But it isn't working in any other browser. // socketprogramming4.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include<io.h> #include<stdio.h> #include<winsock2.h> #pragma comment(lib,"ws2_32.lib") //Winsock Library int main(int argc, char *argv[]) { WSADATA wsa; SOCKET s, new_socket; struct sockaddr_in server, client; int c; char *message; printf("\nInitialising Winsock..."); if (WSAStartup(MAKEWORD(2, 2), &wsa) != 0) { printf("Failed.

Edit: Okay so I found the function I needed which is shutdown(socket,1); which stops sending data but allows data to be received from the client. // socketprogramming4.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include<io.h> #include<stdio.h> #include<stdlib.h> #include <dos.h> #include<winsock2.h> #pragma comment(lib,"ws2_32.lib") //Winsock Library bool send_all(int socket, void *buffer, size_t length) { char *ptr = (char*)buffer; while (length > 0) { int i = send(socket, ptr, length, 0); if (i < 1) return false; ptr += i; length -= i; } shutdown(socket, 1); return true; } int main(int argc, char *argv[]) { WSADATA wsa; SOCKET s, new_socket; struct sockaddr_in server, client; int c; char *message, server_reply[2000]; int recv_size; printf("\nInitialising Winsock..."); if (WSAStartup(MAKEWORD(2, 2), &wsa) != 0) { printf("Failed.
