Questionable software

A list of terrible software, which should be avoided:

Java

As a result of security problems, both Firefox[1] and Chrome block the plugin by default.

Java sacrifices a lot for platform independence, most notably performance and memory-efficiency.

Don't use Java, if you have the choice.

Skype

Microsoft records everything that goes through it, EVERYTING.

Takes large amounts of resources and is very slow. Sending files is very slow and videos are low quality probably because of all the analysis microsoft/NSA does on them.

Use Tox when it comes out instead.
