MRuby: Change the Embedded Development Way

MRuby (Minimalistc Ruby) is a new Ruby implementation made with resources saving in mind. MRuby is a perfect fit for embedded systems world and for limited responsibility applications. Let's understand the state of embedded system development today from the payment devices perspective. In the talk we'll learn how beautiful and useful MRuby is on a device-browser integration or in command line tool.

10. Internet Of Things What? The Internet of Things (IoT) is the network of physical objects or “things" … Each thing is uniquely identifiable through its embedded computing system but is able to interoperate within the existing Internet infrastructure. Internet embedded by Wikipedia
16. Internet Of Things Why??
17. “devices will be wirelessly connected” By ABI Research 30 BILLION Internet Of Things Why??
18. “devices on the Internet of Things by 2020” By Gartnet 26 BILLION “devices will be wirelessly connected” By ABI Research 30 BILLION Internet Of Things Why??
19. “is size of market expected” By Cisco CEO 19 TRILLION “devices will be wirelessly connected” By ABI Research 30 BILLION Internet Of Things Why?? “devices on the Internet of Things by 2020” By Gartner 26 BILLION
20. “are produced for the embedded world” By Embedded Portal 95% OF CHIPS “devices will be wirelessly connected” By ABI Research 30 BILLION “is size of market expected” By Cisco CEO 19 TRILLION Internet Of Things Why?? “devices on the Internet of Things by 2020” By Gartner 26 BILLION
21. Point of Sale devices on Brazil 3 MILLIONS “are produced for the embedded world” By Embedded Portal 95% OF CHIPS “devices on the Internet of Things by 2020” By Gartner 26 BILLION “is size of market expected” By Cisco CEO 19 TRILLION “devices will be wirelessly connected” By ABI Research 30 BILLION Internet Of Things Why??
22. Really?!
24. Backend Developer Thiago Scalone Backend Developer Love Tests, Code and Beer
25. Delivery the code and collect feedback CONTINUOUS DELIVERY Backend App Used To Have Run the entire suite with one command TEST Beautiful code and easy to maintainable BEAUTIFUL API Documentation from code DOCUMENTATION
26. Moving To Cloudwalk Improvement Thiago Scalone Backend Developer Love Tests, Code and Beer
28. WINDOWS XP Eclipse :(
29. Point Of Sale What Is?
30. or even a good filesystem NO OS Point Of Sale What Is?
31. for example pipe or fork LIMITED SYSCALL Point Of Sale What Is? or even a good filesystem NO OS
32. OsModemOpen(); OsPrnOpen(); OsPrnClose(); POORLY API Point Of Sale What Is? for example pipe or fork LIMITED SYSCALL or even a good filesystem NO OS
33. open, read, close NO POSIX Point Of Sale What Is? for example pipe or fork LIMITED SYSCALL OsModemOpen(); OsPrnOpen(); OsPrnClose(); POORLY API or even a good filesystem NO OS
34. your on spec NO ANSIC Point Of Sale What Is? open, read, close NO POSIX or even a good filesystem NO OS for example pipe or fork LIMITED SYSCALL OsModemOpen(); OsPrnOpen(); OsPrnClose(); POORLY API
35. Development Workflow DEVELOPMENT .C PHYSICALLY UPLOAD CUSTOMER FEEDBACK GENERATE .O SIGN TEST MASSIFICATION DEVELOPMENT .C 6 MONTHS …
36. Development Workflow PHYSICALLY UPLOAD 30.000
37. ANYTHING NEW Runtime
38. Mruby Minimalistic Ruby Static C/Ruby Gems High Portable ANSI C Bare Metal Resource Saving Small
40. How???
41. Around The World Open Source MRBGEMS SSL (PolarSSL) IO Socket Regex Zip/Unzip (Miniz)
42. Da Funk Open Source API TO IOTS NEEDS Notifications (Serf) Communication (HTTP, ISO8583, Serial…) Application update Networking (GPRS, WIFI, ETHERNET…) Hardware Abstraction
43. Da Funk + Around DEVICE (IOT) DA FUNK MRBGEMS AROUND SDK/SO APP IO …
44. Da Funk + Around DEVICE (IOT) DA FUNK MRBGEMS AROUND SDK/SO APP IO …
45. Command Line Tool Go(Cgo) + Mruby
46. Command Line Tool Go(Cgo) + Mruby
47. Emulation Go + Thrust + Webruby
48. Notifications With Serf Gossip Protocol By Hashicorp SERF HANDSHAKE KEEP ALIVE (ACK) GIT PUSH EVENT SERF STREAM DOWNLOAD APP
49. So…
