8. FUTUREWEI  Head of US Open Source Program Office  Senior Director of Strategy and Business Development  How HUAWEI treat Open Source
9. What is Open Source?
10. Have You Heard Of  Operations System  Linux/FreeBSD/Android  Version Control  Github/Git/Bitbucket  Deep Learning  Tensorflow/Darkflow/ImageNet/Yolo/Caffe  Programming Language  Nodejs/Go/Python  Browser  Chrome, Firefox
11. Open Source Everywhere
12. What is Open Source  From OSI (Open Source Initiative)  Free Redistribution  Source code  Derived work  No Discrimination Against Persons or Groups/Fields of Endeavor
13. The Opposite Is Closed Source  Microsoft Windows  Microsoft Office  Microsoft Internet Explorer  Mac OSX  Adobe Photoshop  Others
15. Why Open Source?
16. For Software Itself  Given enough eyeballs, all bugs are shallow  Tends to produce better quality software  Hard to insert backdoors  You can watch whole Linux Kernel source code  https://elixir.free-electrons.com/linux/latest/source
17. For Software Itself  Patch on your own schedule  Make it better  When a bug/vulnerability is discovered  Don’t wait the specific vendor/owner to fix it.  You can fix it  Cisco says router bug could be result of ‘cosmic radiation’
18. For Developer  Shift developers from low-value work to high-value work  Don’t reinvent wheels  Stand on the shoulders of giants  If you want to write a simple ”Hallow World” application.  Kernel (support keyboard, monitor, mouse)  Editor (modify the language)  Compiler/Assembler (for existing language)  Write your application printf(“Hello World\n”)
19. For Developer  Make your coding skill better  Readability  Flexibility  Stability  There are also many tools/docs can help you to improve your coding style.  Pylint, jslint, golint, etc.  Coding style reference (google)  Diagnostic tool
20. For Developer  Learn how to work with others.  Document  Version control  Discuss  Peer Review/Code Review  Better coding style  Avoid blind spot
21. For Developer  Gain reputation/opportunity  A story about my friend  Research SDN  ONOS controller, no IPv6 features  Intern  Works on Silicon Valley now.
22. Business How about business?
23. Non-Profit Organization  Linux Foundation  Linux  OpenStack Foundation  OpenStack  Open Networking Foundation  ONOS/CORD
24. Non-Profit Organization  Member/Public  Member fee  High priority support  Board  Lead some open source projects  Standard/Technique
25. Profit Company  Save Time  System Integration Company  Provides  Customized feature  Better support  Other  Provide a product  Partial open source (License)  Enterprise/Community version
26. For Example  Linux  Red Hat Enterprise Linux (Red Hat)  Ubuntu (Canonical)  OpenStack  99Cloud  EasyStack  InwinStack
27. Another-Example CSCC  Save Money  Computer Science Computer Center  For NCTU-CS department  Maintain Linux/BSD workstations  Provide services for CS departments
28. A story
29. How to use open source to build a wireless router?
30. Wireless Router
31. Features (Software)  Web UI management  Traffic/Parental Control/QoS  Security (IPS/IDS/DPI)  VPN Server  Port Forwarding/Port Trigger  Filter/Firewall  IPv6/PPPoE/DHCP/NAT  Dual Homing/LACP/Bonding
32. First  You need to have a kernel
33. By the way  Linux has many friends.  User space tools  Iptable  tc  Kernel function  Netfilter  Tc  Conntrack  Bonding
34. Features (Software)  Web UI management  Traffic/Parental Control  Security (IPS/IDS/DPI)  VPN Server  Port Forwarding/Port Trigger  Filter/Firewall  IPv6/PPPoE/DHCP/NAT  Dual Homing/LACP/Bonding
35. Web UI  Web Server  Nginx/Apace/Lighttpd  Front-end language  JS/CSS/HTML
36. Security (IPS/IDS/DPI)  IPS/IDS  Snort  Suricata  DPI  NDPI  Netifyd
37. VPN  VPN Server  OpenVPN  SoftetherVPN  Linux Kernel support  IPSec  Strongswan  libreswan
38. Combine All
39. How to join Open Source ?
