From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Readability and maintainability, mostly. They are one character long mostly to help handwriting compact formulas, but their pros end there. For software, though:
For readability the loop has to be short, so it is not really a problem, and it is also clear the iterated variable.
Long loops where the iterated variable is called far from the loop are anyway very bad for readability. There is a much worse problem in that code than i and j
