These tutorials focus mainly on OpenGL, Win32 programming and the ODE physics engine. OpenGL has moved on to great heights and I don't cover the newest features but cover all of the basic concepts you will need with working example programs.
Working with the Win32 API is a great way to get to the heart of Windows and is just as relevant today as ever before. Whereas ODE has been marginalized as hardware accelerated physics becomes more common.
Games and graphics utilities can be made quickly and easily using game engines like Unity so this and Linux development in general will be the focus of my next tutorials.
Before modern tools?
Before delta wing aircraft?
Before modern archaeology?
A face with a pyramidal shadow?
Before heavy machinery?
I would also like to direct your attention to a very good site dedicated to a quite feasible theory as to the fate of Atlantis, the theory is very well explained and presented in lay terms. The site is most likely presented this way because, at present only lay scholars are giving the author the courtesy of an open mind and serious consideration. The scientific community has other more pressing issues such as making a living rather than entertaining new ideas which may force them to rethink all that they were taught to believe. The site is here at Atlantis in Antarctica
