What is a stream?
...ich can be accessed in sequential order. Typical operations on a stream:
read one byte. Next time you read, you'll get the next byte, and so on.
read several bytes from the stream into an array
seek (move your current position in the stream, so that next time you read you get bytes from the new po...

How to read a single character from the user?
Is there a way of reading one single character from the user input? For instance, they press one key at the terminal and it is returned (sort of like getch() ). I know there's a function in Windows for it, but I'd like something that is cross-platform.

multiprocessing: sharing a large read-only object between processes?
...cture with lots of workers, do this.
Write each worker as a "filter" – reads intermediate results from stdin, does work, writes intermediate results on stdout.
Connect all the workers as a pipeline:

Each process reads, doe...
Purpose of memory alignment
...s of cache memory that data must be pulled through; supporting single-byte reads would make the memory subsystem throughput tightly bound to the execution unit throughput (aka cpu-bound); this is all reminiscent of how PIO mode was surpassed by DMA for many of the same reasons in hard drives.
The C...
How can I read large text files in Python, line by line, without loading it into memory?
I need to read a large file, line by line. Lets say that file has more than 5GB and I need to read each line, but obviously I do not want to use readlines() because it will create a very large list in the memory.

Why is reading lines from stdin much slower in C++ than Python?
I wanted to compare reading lines of string input from stdin using Python and C++ and was shocked to see my C++ code run an order of magnitude slower than the equivalent Python code. Since my C++ is rusty and I'm not yet an expert Pythonista, please tell me if I'm doing something wrong or if I'm mis...
Why is iostream::eof inside a loop condition (i.e. `while (!stream.eof())`) considered wrong?
...
Because iostream::eof will only return true after reading the end of the stream. It does not indicate, that the next read will be the end of the stream.
Consider this (and assume then next read will be at the end of the stream):
while(!inStream.eof()){
int data;
// yay...
