You can reverse the direction of a ratchet by hitting with an equal or higher amount of force it came at you with.

A learning management system (LMS) is a software application for the administration, documentation, tracking, reporting and delivery of educational courses or training programs.
Software has to be reliable so that it does not create conflict or negative feelings amongst those who use it.
In this world where humans increasingly rely on the internet and software for information, programmers have to take special care so as to ensure that the members of the society are not affected negatively.
For instance, there have been moments when software led to negative effects such as:
- when Goøgle's algorithm tagged a black couple as gorillas
- Facebøok's algorithm tagged black men as gorillas
- Goøgle maps gave people the wrong directions
These are but a few instances where algorithms have messed up.
We can therefore conclude that it is important that programmers take extra care when designing programs so that they do not lead to negative feelings.
