13/ 47 What you won’t learn in your courses

14/ Version Control

15/ 47 Version Control  Used to keep track of changes within your project.

16/ 47 Version Control  Used to keep track of changes within your project.  Who made what changes, why, when

17/ 47 Version Control  Used to keep track of changes within your project.  Who made what changes, why, when  Can look at history of changes

18/ 47 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/ 47 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/ 47 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/ 47 Version Control  Create an account and store all your projects on there. (For all your future courses too)

22/ 47 Version Control  Create an account and store all your projects on there. (For all your future courses too)  Also serves as a portfolio

23/ 47 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/ Other Programming Languages

25/ 47 Programming Languages  Already know Java.

26/ 47 Programming Languages  Already know Java.  Will learn C/C++ for next courses.

27/ 47 Programming Languages  Already know Java.  Will learn C/C++ for next courses.  Try to learn it by yourself too (pointers!)

28/ 47 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/ 47 Programming Languages  Can write programs in Python/Ruby very quickly.

30/ 47 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/ 47 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/ 47 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/ 47 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/ Unix/Linux

35/ 47 Linux  Very useful to be proficient at the Linux (or Mac) command line.

36/ 47 Linux  Very useful to be proficient at the Linux (or Mac) command line.  High-learning curve, but very powerful.

37/ 47 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/ 47 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/ 47 Linux  Learn a text editor:

40/ 47 Linux  Learn a text editor:  VIM  My personal choice.  High learning curve, but once again very powerful.

41/ 47 Linux  Learn a text editor:  VIM  My personal choice.  High learning curve, but once again very powerful.  Emacs  Also very good and powerful.

42/ Mobile Development

43/ 47 Mobile Development  Android and iOS obviously very popular.

44/ 47 Mobile Development  Android and iOS obviously very popular.  You know Java now – try to make some apps.

45/ 47 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/ 47 Conclusion  Need to put in a lot of effort yourself.  You won’t learn everything in class

47/ 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.
