1. Why  Ruby?   View  from  business  aspect  
2.     They  said,  it  is  difficult  for  companies  to  find   rubyists,  and  for  rubyists  to  find  companies...    
3. Fact:  In  Craigslist   21%   12%   10%   9%   6%   3%   3%   0%   5%   10%   15%   20%   25%   PHP   C++   C   Javascript   Java   C#   Ruby   %  of  job  pos;ngs  
4. Another  fact:  In  LinkedIn   19000   1300   700   0   2000   4000   6000   8000   10000   12000   14000   16000   18000   20000   PHP   Python   Ruby   #  of  programmers  
5.     So,  does  it  mean  we  have  to   move  on  from  Ruby?    
6.     NOOOO!!!!  
7. Back  then  in  the  end  of  2009...   Why  use  Ruby?  Isn’t  it  alien  to   many  Indonesian  programmers?   Nugroho ‘xinuc’ CTO Bukalapak, ex CTO Suitmedia Well,  well,  let  me  give  you  my   view...  
8. Ruby  is  fun!!!  
9. class ThisIsAClassIDontReallyWantToNameButJavaMakesMe! {! !public static void main() {! ! !System.out.println("Hello World");! !}! }!
10. puts ‘Hello World’!
11. import java.io.File;! import java.io.InputStream;! ! // ... declare class, etc., then ...! ! public byte[] justReadMeAFilePlease() {! try {! !file = new File("my-file.txt");! !fis = new FileInputStream(file);! !byte[] b = new byte[(int) file.length()];! !fis.read(b);! !return b;! } catch (Exception e) {! !e.printStackTrace();! }! }!
12. contents = File.read ‘my-file.txt’!
13. Does  that  maXer?...  Sure  thing!  
14. Bonus:  Usability  
15. Even  if  the  job  fact  is  true,  yet...           People  don't  learn  Ruby  to  get  them  job;  they   learn  it  because  they  genuinely  like  to  program   and  aren't  sa;sfied  with  languages  they  know  
16. The  Paradox  (1)     If  we  choose  to  write  its   soKware  in  esoteric   language,  we  will  be  able   to  hire  beLer   programmers,  because  we   will  aLract  only  those  who   cared  enough  to  learn  it  
17. The  Paradox  (2)         The  language  to   learn,  if  you  want  to   get  a  good  job,  is  a   language  that  people   don't  learn  merely  to   get  a  job  
18. Not  many  companies  realize,  yet  don’t   worry,  they  are  companies  you   probably  want  to  work  for  
19. What  about  startup?      
20. It  is  even  more  true!      
21. Case:  one  of  clients  handled  in   Suitmedia  
22. In  summary,  good  alternacve  for   business,  esp.  startup   1.  Gives  pleasant  and  fun  for  programmers   (hence,  increased  produccvity)   2.  AXracts  overall  beXer  programmers  (hence,   beXer  company  performance)   3.  Highly  usable  (hence,  good  support  for  long   term  maintenance)   4.  Provides  unique  approach  (hence,  leading   company  value  proposicon)
