The primary advantage of two’s complement over one’s complement is that two’s complement only has one value for zero. One’s complement has a “positive” zero and a “negative” zero. Next, to add numbers using one’s complement you have to first do binary addition, then add in an end-around carry value. Two’s complement has only one … Read more
Unix has no distinction between text and binary files, which is why you can just cat them together: cat file1 file2 > target_file If target_file already exists and you want to append content to it, instead of overwriting, use instead: cat file1 file2 >> target_file

int given base 2 and then hex: >>> int(‘010110’, 2) 22 >>> hex(int(‘010110’, 2)) ‘0x16’ >>> >>> hex(int(‘0000010010001101’, 2)) ‘0x48d’ The doc of int: int(x[, base]) -> integer Convert a string or number to an integer, if possible. A floating point argument will be truncated towards zero (this does not include a string representation of … Read more
As of December 11, 2012 the Downloads feature on GitHub is deprecated. The article Distributing large binaries recommends using an external service: We recommend Amazon S3 for storage paired with CloudFront for serving via CDN, or other services such as SourceForge. However, since 2d July 2013, you now can define a release. Releases, a workflow … Read more
You can determine that it is likely to be one of those formats by looking at the first few bytes. You should then test to see if it really is one of those, using an integrity check from the associated utility for that format, or by actually proceeding to decompress. You can find the header … Read more
Here are some tips that come to mind: From my experience, interactive scripting languages (I use Python) can be a great help. You can write a simple framework to deal with binary streams and some simple algorithms. Then you can write scripts that will take your binary and check various things. For example: Do some … Read more
Reading and writing binary files is pretty much the same as any other file, the only difference is how you open it: unsigned char buffer[10]; FILE *ptr; ptr = fopen(“test.bin”,”rb”); // r for read, b for binary fread(buffer,sizeof(buffer),1,ptr); // read 10 bytes to our buffer You said you can read it, but it’s not outputting … Read more
In Java 7: int i = 0b10101010; There are no binary literals in older versions of Java (see other answers for alternatives).
The problem is that at least 32 characters of the ASCII character set are ‘control characters’ which may be interpreted by the receiving terminal. E.g., there’s the BEL (bell) character that makes the receiving terminal chime. There’s the SOT (Start Of Transmission) and EOT (End Of Transmission) characters which performs exactly what their names imply. … Read more
