I try to learn certain areas of computer science exhaustively; then I try to digest that knowledge into a form that is accessible to people who don't have time for such study._ +There it is. +Computing takes time. +There's no silver bullet yet, and we as programmers have to take our time to think about problems in depth. +There have been many comments on the peculiar style of teaching and way of being of Edsgar Dijkstra, but I believe he has made some really good points about this too. +What describes my experience over the last 3 years well is his quote: _The competent programmer is fully aware of the strictly limited size of his own skull; therefore he approaches the programming task in full humility[...]_. +I think this the approach to take, because so often computers help us verify and point out that we indeed really don't know anything, we are just pretending we do. + -- cgit v1.2.3
