Transcript

1. A web console to control nanosatellites Nahuel Garbezza
2. context Satellogic builds nanosatellites using open hardware and software technologies @CubeBug1 launched, @CubeBug2 to be launched soon they needed a visual console for improving the interaction with the satellites
3. context Console Radio Satellite sockets
4. let’s see some of the key aspects of the project
5. #1: discover the domain we did test-driven development from the beginning a lot of concepts & patterns emerged
6. let’s browse some classes :-) #1: discover the domain
7. #2: visual sending & reception of packages web interface using Seaside components a lot of JQuery / Ajax integration with DataTables JQuery plugin
8. #2: visual sending & reception of packages demo: let’s see the console running!
9. #3: display charts timeline charts using Highstock JS library (bindings with Smalltalk)
10. #3: display charts
11. #4: parse command definitions code that runs in the satellite is written in C we used PetitParser to extract the command definitions
12. #4: parse command definitions demo: browse some PetitParser rules configuration from the web interface
13. #5: let the users write custom scripts built-in commands are ‘primitives’ console users know Smalltalk so… we let them write Smalltalk code scripting support using metaprogramming
14. #5: let the users write custom scripts demo: creating and sending scripts from the console some technical details
15. conclusions great opportunity to work on a real project using Smalltalk personally, to gain experience on TDD, OO design and Web development
16. thanks to Hernán Wilkinson Gera Richarte
17. end questions/comments are for sure welcome :-)
