the past is still relevant to the present

There is a Chinese saying that goes "The past can still be used in the present."

My interpretation goes beyond the literal that says traditions should be still practised in modern days. My thoughts are that the powerful at present make use of the dead to keep themselves in power.Whether their bodies are mummified or even their mere picture inspires blind obedience,the dead can be powerful tools to be used by the present to serve their purpose.Can the dead ever rest in peace ? when can they be let go of?
the pharoahs wanted to extend their power from the afterlife,the dead leader is preserved forever,the dead is immortalised or expected to enrich the present?

asus computers are lousy

I bought an asus laptop and the pc model sucks.The screen black out within less than 24 hours and when it was supposedly repaired with a torture test done .I took it back to the shop at Kendo,and the next day the screeen went black although it was on direct current.I took 7 videos on my instant camera and I'm going to send it back to asus to show their poor quality control in terms of manufacturing.Manufacturers who don't improve should not expect repeat customers or any customer loyalty.I have no faith in products that don't work after 24 hours. Period.My acer has been consistently more reliable when my boy has used his for 5 years with no problems at all.
