+# Introduction
+According to Google Scholar [@google2016], there are more than 10,000 articles that mention 'Debugging' in their title.
 With such an amount of research on this topic, it is a pity it is still not adequatly addressed in programming texts [@mccauley2008debugging].
 Research by Cambridge university shows developers spend around 50% of their time finding and fixing bugs [@britton2013reversible].
 This paper presents the debugging basis to become more effective at it.
 
-## You're probably non-structured debugger 
+## You're probably non-structured debugger
 If you are a novice, there is a good chance you are using non-structered methods to debug programs. [SOURCE]
 Education currently lacks proper instruction of debugging. [SOURCE]
 You might not even be a novice. [SOURCE]

 ### Proof yourself wrong
 One of the most powerfull techniques to cover a lot of ground is to always try to proof yourself wrong.
 When you have an hypothesis of a problem, test or check if you can proof your hypothesis wrong.
