For an obfuscation program I am writing in Java, I need to find a way to get a value at a specific address. For example, in a program I opened in a hex editor, at the address 0000001F is the hex value "00". Furthermore, is it possible to write to a specific memory address?

What am I doing wrong - or are single digit hex numbers a special case ? Java 1.5.x. ...

So I have kind of a ignorant (maybe?) question. I'm working with writing to a serial device for the first time. I have a frame [12, 0, 0, 0, 0, 0, 0, 0, 7, 0, X, Y] that I need to send. X and Y are checksum values. My understanding in using the pyserial module is that I need to convert this frame into a string representation. Ok that's f...

I have a byte array represented by hex values, these are time durations. The data could be converted to integer values and multiplied by a constant to get the timings. The decoding of the data will be saved to a file as a series of hex strings. What would be an efficient way of manipulating hex values? I was looking at performance iss...

What I understand that hexadecimal numbers can be placed into string using \x. For example 0x41 0x42 can be placed in string as "\x41\x42". char * ptr = "\x41\x42" ; printf( "%s\n" , ptr ) // AB \x is discarded and 41 is considered as a hex by the compiler. But if I pass it to my program through command line arguments, it does not wo...
