The two common reasons you may want to store binaries in a Version Control System are (written in 2009): store external third-party libraries. Usually one stores them into a Maven repository, but to store them into SVN allows you to have one and only one referential for all your need: get your sources, and get … Read more
The next draft (hybi-07) of the WebSockets specification is being implemented in most browsers and it will add built-in binary support to the protocol and API. However, until then, WebSockets payload is encoded as UTF-8. In order to send binary data you must use some way of encoding the binary data as UTF-8. There are … Read more
In case you don’t have this LINQ fetish, so common lately, you can try the normal way string input …. int numOfBytes = input.Length / 8; byte[] bytes = new byte[numOfBytes]; for(int i = 0; i < numOfBytes; ++i) { bytes[i] = Convert.ToByte(input.Substring(8 * i, 8), 2); } File.WriteAllBytes(fileName, bytes); LINQ is great but there … Read more
Here’s a way to convert binary numbers to ASCII characters that is often simple enough to do in your head. 1 – Convert every 4 binary digits into one hex digit. Here’s a binary to hex conversion chart: 0001 = 1 0010 = 2 0011 = 3 0100 = 4 0101 = 5 0110 = … Read more
There’s a trick for just getting the 1’s out of the binary representation without having to iterate over all the intervening 0’s: def bits(n): while n: b = n & (~n+1) yield b n ^= b >>> for b in bits(109): print(b) 1 4 8 32 64
Use toString() instead of parseInt: 11..toString(2) var str = “11”; var bin = (+str).toString(2); console.log(bin) According JavaScript’s Documentation: The following examples all return NaN: parseInt(“546”, 2); // Digits are not valid for binary representations
Which platform are you on? You could try this recipe if you’re on Windows (the link suggests it’s Windows specific anyway). if sys.platform == “win32”: import os, msvcrt msvcrt.setmode(sys.stdout.fileno(), os.O_BINARY) There are some references on the web that there would/should be a function in Python 3.1 to reopen sys.stdout in binary mode but I don’t … Read more
This did the trick for me: :%!xxd -b
This seems to work for me: grep –only-matching –byte-offset –binary –text –perl-regexp “<\x-hex pattern>” <file> Short form: grep -obUaP “<\x-hex pattern>” <file> Example: grep -obUaP “\x01\x02” /bin/grep Output (Cygwin binary): 153: <\x01\x02> 33210: <\x01\x02> 53453: <\x01\x02> So you can grep this again to extract offsets. But don’t forget to use binary mode again.
