  Well if you have no natural primary key for your table then you can generate your own surrogate keys.

  Careful with GUIDs though, they consume 16 bytes each and can be a pain as I've been finding out recently!

  It takes a minimal capacity for rational thought to see that the corporate 'free press' is a structurally irrational and biased, and extremely violent, system of elite propaganda.

  Society has varying and conflicting interests; what is called objectivity is the disguise of one of these interests - that of neutrality. But neutrality is a fiction in an unneutral world. There are victims, there are executioners, and there are bystanders... and the 'objectivity' of the bystander calls for inaction while other heads fall.
