Data Structures for Text Sequences (1998) [pdf]

I invented the "piece table" data structure independently, while writing a DOS text editor in 1990s, presented it at a symposium in my faculty and got laughed off. 20 years later I stumble into this PDF describing it as a worthwhile data structure. LOL

I don't think I ever really understood what a descriptor was until reading this, and now I feel really stupid but at the same time grateful!

Is the typo in the first sentence (the letters in "to" are reversed) a joking reference to the the topic "text SEQUENCE"?

This is very interesting for someone who dreams about making a text editor!

My alma mater.
