For me issue is "or by using materials, tools or knowledge made available through your employment" when you combine it with "whether during or after the termination of your employment" and "shall remain in full force and effect following any termination"

So basically, let say I do not know Scala and I learn it there or I use GoDaddy to register domain, according to contract I will never be able to use those anywhere else, and if I do I will need to handover things I have done?!
