I believe all (or at least most) of the "quotes" have been re-purposed/altered by the [blog's] author. e.g. "Every line of code is written without reason, maintained out of weakness, and deleted by chance" is based on Jean-Paul Sartre's actual quote[1] "Every existing thing is born without reason, prolongs itself out of weakness and dies by chance."

It's kinda sad that no one else seams to be picking up on this. To lead off with that intentionally altered quote and looking at code in terms of how existentialists frame reality is the most significant insight.

Wasn't it Sartre who famously wrote Three o'clock is both too early and too late to start refactoring?
