Guerrilla  programming •  This  talk  is  about  a  pa$ern.     •  It  is  not  about  design  paAerns.     •  It’s  about  how  our  industry  (“so#ware  engineering”)  moves   •  Problems  go  through  three  stages:   •  Discovery   •  Experimenta9on   •  Synthesis   •  For  example,  speaking  of  the  Hollywood  image  of  hackers...  
9. Warning   •  The  following  material  is  probably  not  right  for  your  case.     •  It’s  right  for  some  people,  in  some  specific  situa9ons  and  at  some   specific  9mes.

20. OOP  is  about  taming  complexity  through  modeling,  but  we  have  not   mastered  this  yet,  possibly  because  we  have  difficulty  dis9nguishing   real  and  accidental  complexity.   I  believe  that  to  make  further  progress  we  must  focus  on  change  and   how  OOP  can  facilitate  change.  A#er  all  these  years,  we  are  s9ll  in  the   early  days  of  OOP  and  understanding  what  it  has  to  offer  us.     Oscar  Nierstrasz   [Banquet  speech  given  at  ECOOP  2010.  Maribor,  June  24,  2010]     hAp://blog.jot.fm/2010/08/26/ten-­‐things-­‐i-­‐hate-­‐about-­‐object-­‐oriented-­‐programming/comment-­‐page-­‐2/

Many Google services see releases multiple times a week, and almost everything in Google is developed on mainline.” Jez Humble - The Case for Continuous Delivery hAp://www.thoughtworks.com/insights/blog/case-­‐con9nuous-­‐delivery  
36. “SQL  databases  are  fundamentally  non-­‐scalable,  and  there  is   no  magical  pixie  dust  that  we,  or  anyone,  can  sprinkle  on   them  to  suddenly  make  them  scale.”         Adam  Wiggins  -­‐  SQL  Databases  Don't  Scale   hAp://adam.herokuapp.com/past/2009/7/6/sql_databases_dont_scale/
