  7. 7. "I feel that most of the things that we arelearning how to do are by trial and error basis.... You can’t just expect to code something rightaway and get it right. It takes time and patience-- A LOT of patience -- before actually almostthrowing your computer out the windowbecause you have no idea why your codedoesn’t work and then you come to find out youare missing a semicolon somewhere inhundreds of lines of C++ code!!!! >:(" Computers are stupid! And: To grow, fail early and often
  8. 8. "Today’s studio has me thinking more about howthere are so many possible variances in logicalpathways that defining computer logic has somany inherent variances across the different textprograming languages.

Will there ever be a way towrite style, content, and structure with a single language?""It is crazy to think that our exercise only involved working withone page, whereas creators of Thematic Research Collectionshave to mark-up thousands of pages of research. I wonder howmuch time and resources such tasks take up."
  11. 11. "[W]e created a digital representation ofthe text with HTML but used CSS tomake it resemble its original analogform. Don’t you think we are limitingourselves by doing so?"
