Writing in binary

Recently a site was discovered for Project Offset (http://www.projectoffset.com/astormiscoming/)

At the bottom of the page is the binary code:
01101011 01100101 01100101 01110000 00100000 01100111 01101111 01101001 01101110 01100111

Which translates to decimal:
107 101 101 112 32 103 111 105 110 103

Which, in ASCII, is:
k e e p [:space:] g o i n g

My first thought upon finding this out was how awsome it was they hid a message in binary, but my second one was "How exactly does one translate words to binary?". Are their any methods or programs out their to achieve this? I think it would be neat to write messages in binary just for kicks.

 

There are programs that do it for you, like here.

In C, one could do:

for (i=0;str;i++) printf("%08b ",str);

I don't know what compiler you are using, but that isn't standard.

Code:

#include <stdio.h>
int main( int argc, char **argv )
{
    int arg;
    int i;
    int b;
 
    for( arg = 1; arg < argc; arg++ )
    {
        for( i = 0; i < strlen( argv[ arg ] ); i++ )
        {
            for( b = 0; b < 8; b++ )
            {
                printf( "%c", '0' + ( ( argv[ arg ][ i ] >> ( 7 - b ) ) & 1 ) );
            }
 
            printf( "\n" );
        }
    }
}

Anyone share my first thought? That there are far better uses for C (or Perl, or VB, or whatever) than this?

 

In case you need the information : words are made up of characters, characters in ASCII are represented by numbers, numbers can be translated into a base-2 (hey that's binary! ) representation. Have a look at wikipedia for that

 

it would depend on the convention. mobile phones for example dont use the same standards (they used 5bits per byte in messaging etc)

 

there was a time where i could write pages of text in binary, using my mind and a pen.

There's a logic to it, but i don't remember much. I think every letters starts with 01, then the third number, 0 or 1, depends if its a Big or a small letter, 1 for big 0 for small i think. The first from the right always switch from 0 to 1 at each letter, the second (always from the right) switch at every four, but is already at the second zero at the start, the 3rd from the right switch at every 8 but already is at the second 0 too, and shit like that.


It was funny in a geek way.
