13. What you won’t learn in your courses

14. 1. Version Control

15. Version Control • Used to keep track of changes within your project.

16. Version Control • Used to keep track of changes within your project. • Who made what changes, why, when

17. Version Control • Used to keep track of changes within your project. • Who made what changes, why, when • Can look at history of changes

18. Version Control • Used to keep track of changes within your project. • Who made what changes, why, when • Can look at history of changes • Can revert to previous version at any time

19. Version Control • Used to keep track of changes within your project. • Who made what changes, why, when • Can look at history of changes • Can revert to previous version at any time • Git and Mercurial – two version control systems

20. Version Control • Used to keep track of changes within your project. • Who made what changes, why, when • Can look at history of changes • Can revert to previous version at any time • Git and Mercurial – two version control systems • GitHub (free website for your repositories) • Google Code Repositories

21. Version Control • Create an account and store all your projects on there. (For all your future courses too)

22. Version Control • Create an account and store all your projects on there. (For all your future courses too) • Also serves as a portfolio

23. Version Control • Create an account and store all your projects on there. (For all your future courses too) • Also serves as a portfolio • Look up tutorials online on how to use Git/Mercurial

24. 2. Other Programming Languages

25. Programming Languages • Already know Java.

26. Programming Languages • Already know Java. • Will learn C/C++ for next courses.

27. Programming Languages • Already know Java. • Will learn C/C++ for next courses. • Try to learn it by yourself too (pointers!)

28. Programming Languages • Already know Java. • Will learn C/C++ for next courses. • Try to learn it by yourself too (pointers!) • But should also try to learn other languages like: • Python (used at Google/NASA/IBM), Ruby (Amazon), Perl (Amazon), Lua (Game Scripting), C# (for Windows), Javascript (Web Programming), Objective-C (Macs, iOS)

29. Programming Languages • Can write programs in Python/Ruby very quickly.

30. Programming Languages Task: • Open a text file named 'list.txt' • Create a list of the lines with more than 5 characters in the text file Python program: mylist = list()myfile = open('list.txt')for line in myfile:    if len(line) > 5:mylist.append(line)

31. Programming Languages Task: • Open a text file named 'list.txt' • Create a list of the lines with more than 5 characters in the text file • Python program: mylist = list()myfile = open('list.txt')for line in myfile:    if len(line) > 5:mylist.append(line)

32. Programming Languages Task: • Open a text file named 'list.txt' • Create a list of the lines with more than 5 characters in the text file • Python program: (“long” version) mylist = list()myfile = open('list.txt')for line in myfile:    if len(line) > 5:mylist.append(line)

33. Programming Languages Task: • Open a text file named 'list.txt' • Create a list of the lines with more than 5 characters in the text file • Even shorter version: mylist = [line for line in open('list.txt') if len(line) > 5]

34. 3. Unix/Linux

35. Linux • Very useful to be proficient at the Linux (or Mac) command line.

36. Linux • Very useful to be proficient at the Linux (or Mac) command line. • High-learning curve, but very powerful.

37. Linux • Very useful to be proficient at the Linux (or Mac) command line. • High-learning curve, but very powerful. • Learn unix commands, bash scripting, Makefiles for compiling, etc.

38. Linux • Very useful to be proficient at the Linux (or Mac) command line. • High-learning curve, but very powerful. • Learn unix commands, bash scripting, Makefiles for compiling, etc. • Used for development everywhere (except for Microsoft)

39. Linux • Learn a text editor:

40. Linux • Learn a text editor: • VIM • My personal choice. • High learning curve, but once again very powerful.

41. Linux • Learn a text editor: • VIM • My personal choice. • High learning curve, but once again very powerful. • Emacs • Also very good and powerful.

42. 3. Mobile Development

43. Mobile Development • Android and iOS obviously very popular.

44. Mobile Development • Android and iOS obviously very popular. • You know Java now – try to make some apps.

45. Mobile Development • Android and iOS obviously very popular. • You know Java now – try to make some apps. • Good way to practice and show people what you made. • Maybe also make some money

46. Conclusion • Need to put in a lot of effort yourself. • You won’t learn everything in class

47. Conclusion • Need to put in a lot of effort yourself. • You won’t learn everything in class • Hopefully you enjoyed the course and (importantly) learned a lot.
