To color code your prompt on a Mac, use the following template:
\[\033[COLOR_CODE_HERE\]PROMPT_ESCAPE_OR_TEXT_HERE\[\033[0m\]
----------------------------------------------------------------------------
Most Linux distributions use a little different format:
\e[COLOR_CODE PROMPT_ESCAPE\e[0m

#TF-IDF
TF-IDF = tf * idf = tf * log(N/n)

tf: number of times a term appears in a document
N: total number of documents
n: number of documents that contain a term

TF-IDF stands for "Term Frequency, Inverse Document Frequency". 
It is a way to score the importance of words (or "terms") in a 
document based on how frequently they appear across multiple documents.

All POSIX semaphore functions and types are prototyped or defined in semaphore.h. To define a semaphore object, use
  sem_t sem_name;
  
To initialize a semaphore, use sem_init():
  int sem_init(sem_t *sem, int pshared, unsigned int value);
sem points to a semaphore object to initialize
pshared is a flag indicating whether or not the semaphore should be shared with fork()ed processes. LinuxThreads does not currently support shared semaphores
value is an initial value to set the semaphore to
Example of use:
  sem_init(&sem_name, 0, 10);
