| Some possible implementations of the Bresenham Algorithms in C. | |
| The Bresenham line algorithm is an algorithm which determines which points in an | |
| n-dimensional raster should be plotted in order to form a close approximation | |
| to a straight line between two given points. | |
| It is commonly used to draw lines on a computer screen, as it uses only integer | |
| addition, subtraction and bit shifting, all of which are very cheap operations | |
| in standard computer architectures. | |
| It is one of the earliest algorithms developed in the field of computer graphics. | |
| A minor extension to the original algorithm also deals with drawing circles. |

I often find myself using Byobu on a Linux machine when connected to it over SSH. In doing so, I've noticed that many of the documented keyboard shortcuts don't work. This can be due to the native PC's OS intercepting certain keys, or possibly other reasons.
Below is a cheatsheet with Byobu features I have found usually work when run over a SSH connection.
| Action | Windows + Putty to Ubuntu | MacOS + Terminal to Ubuntu |
|---|---|---|
| Help menu | BASH: byobu-config | FN-F1 |
| Create new window | CTRL-a c | CTRL-a c or FN-F2 |
