DITP and The black triangle

A hacker news submission references the "The black triangle" blog note. I can only backup the author since I have experienced this many time.

For short, with some programs the visible part of it is merely just a black triangle while the invisible part may be complex or required a lot of efforts to achieve. The black triangle is then generally just a simple visual example to prove that the underlying system works.

That is the state of progress of DITP. I'm working to get the black triangle to become visible. In doing so I'm also writing the protocol specification so that the protocol may be reviewed and implemented by third parties in other languages or libraries.

The black triangle is like the first fruits of a fruiterer tree that may, sometime, took a long time to grow up to the point to be able to produce fruits.
