Fine-grained change detection in structured text documents [DocEng 2014]

Abstract Detecting and understanding changes between document revisions is an important task. The acquired knowledge can be used to classify the nature of a new document revision or to support a human editor in the review process. While purely textual change detection algorithms offer fine-grained results, they do not understand the syntactic meaning of a…

System efficiency vs. fragility

I just listened to Padmasree Warrior on a Commonwealth Club podcast. Ms Warrior is the chief strategy officer at Cisco. The podcast contains lots of interesting insights and projections (as well as some incorrect statements, specifically that Google was the first search engine company and capitalized on a first-mover advantage).

Every real-world specification is an underspecification. So, well, I say that, but I doubt that I’m…

Every Complex System that Works Started Out as a Simple System that Worked

The title of this blog post is my paraphrasing of a “law” from the tongue-in-cheek but nevertheless somewhat serious book “Systemantics” by John Gall.
