Transcript

1. The Mün and Back: A Kerbal Tale
2. The Mün and Back: A Kerbal Tale Enterprise Kerbal Space Program (Foundation) in Containers, as a service, for microservices, at scale, in the cloud, using Arduino.
3. The Mün and Back: A Kerbal Tale 5 completely separate talks
4. HI THERE HELLO
5. Who We Are - Paris Buttfield-Addison – Srs Troublemaker, @parisba - Jon Manning – Troublemaker, @desplesda - Paul Fenwick – CKAN author, @pjf - Alasdair Allan – Did PhD with Scott Manley, @aallan - Tim Nugent – has more boardgames than you, @the_mcjones We’re the authors of The Kerbal Book, coming soon! Also isn’t it great co-authors can edit slides? Yes, it’s fantastic!
6. We’re from Australia. And Scotland.
10. What can you do?
11. An Unlimited Supply of Free Rockets We can use KSP to test some space hypotheses, such as...
12. “I Thought Space Was Up”
14. Let’s Go To Space, Which Is Up We’ll launch a rocket and go straight upwards, and see what happens
16. Observations It falls back down to the ground! • BUT WHAT HAPPENED TO ZERO GRAVITY? • THERE’S NO GRAVITY IN SPACE? • WHY DID IT FALL DOWN, HUH, ROCKET SCIENTIST? • THIS PROVES SPACE IS FAKE
22. Creative Ways to Launch Your Rocket • Spaceflight is dangerous and expensive • NASA, ESA and the rest of the gang can’t afford to take unnecessary risks
24. Experiment 1 “Can we use a catapult to get to space?”
26. Result: I… guess?
27. Experiment 2 “Why don’t we try launching rockets sideways? Give ‘em wings, they’ll probably go up”
29. Result: More experimentation required.
30. Experiment 3 “Can we build a rocket designed to usefully explode?”
32. Result: Yes, and it’s awesome.
33. PART TWO WE HAVE TO GET OFF THIS ROCK
34. Problem: We only have one planet
35. Solution: Get more planets
36. Problem: Humans need stuff like air, water, and food
37. Solution: DIFFICULT TO SOLVE.
38. But we have to try!
39. Let’s Model a Colonization Project We’re going to COLONISE!
40. Options: - The Mün - Duna - Minmus - Eve - More distant planets? Where?
41. Option #1: Mars Duna + Really pretty + Atmosphere for aerobraking - Far away - Transit windows are annoying
42. Option #2: Mün + Close by + Easiest to get to - Ugly - Bumpy
43. Option #3: Minmus + Pretty close by + Lots of flat surfaces, good for stable landings + Pretty + Mint ice cream flavoured - Slightly trickier to get to than Mün
44. Decision: Minmus! - What do you need in space? - Supplies - Power - Consumable resources - Eventually, the ability to build more rockets
45. Missions - Send some initial people - Establish some infrastructure - Locate resource deposits - Send the rest
46. Equipment - Pioneer Pod - Nuclear reactor - Greenhouse - Habitat - Expando-Tubes for connecting - Skycranes to lower into place - Wheels to position everything
47. Life Support Mod - USI Life Support - Nutritional Optimised Meal Supplement (“N.O.M.S.”) - Kerbals eat it and it turns into Mulch - Greenhouses can convert Mulch back to Supplies - But not all of it
48. Modular Kolony System Mod - Adds a bunch of features: - Habitation - Hydroponics - Resource extraction - Parts manufacturing - Designed for both in-space and on-planet colonisation
50. Lessons Learned Space colonisation is REALLY HARD
52. The Comprehensive Kerbal Archive Network (CKAN) PART THREE
53. KSP is a great game
54. KSP with mods is an AWESOME game
55. Installing mods by hand?
56. Realistic Progression “Lite”
60. “I’ll hack something together..”
61. “Like apt-get for KSP”
62. 300 hours later...
65. Cross-platform minimal dependencies
66. MIT/CC-0 license
67. Citizen Code of Conduct
68. Implements the Debian spec

70. 15,000+ active users (Downloads in the last week)
71. Almost 900 mods (Includes many pre-1.0 only mods)
72. ~ 3,500 releases
73. 200+ contributors (Yes, really!)
74. Infrastructure Sponsorship (AWS)
75. Software Development Grant (OSDC)
76. Patreon Campaign patreon.com/pjf0
78. I miss playing KSP
79. Mods are really easy Seconds instead of hours
80. Decades of human joy delivered
81. “Seriously. I mod dozens of games, everything from Age of Empires to Sins of a Solar Empire to Bethesda stuff, and not one game out there has anything quite like CKAN. It's worlds ahead of any other mod manager program for any other game I've ever played” — /u/Pyrhhus

83. Part Four Hardware!! Now with added…
85. Best to start out here!
86. But then add cardboard ...
87. … and hard cases!
91. • KSPSerialIO o https://github.com/unixunion/KSPSerialIO • Telemachus o https://github.com/richardbunt/Telemachus The ways and means…
92. Telemachus
93. WebSocket API Data can be collected from KSP using the Telemachus web socket API, which sits on top of the rfc6455 web socket protocol. To connect to the Telemachus web socket server use a URL of the following form. ws://<ip-address>:<port>/datalink
94. SerialIO https://github.com/zitron-git/KSPSerialIO https://github.com/unixunion/KSPSerialIO
95. DEMO TIME!
96. Part Five What people are doing with KSP
97. aka Tim has opinions about KSP
98. The Squad way of playing KSP 1. Start a new game 2. Pick an easy mission 3. Finish it 4. Pick a harder mission 5. Finish it 6. Repeat Step 4
99. How I think people play 1. Get confused 2. Manage to not blow up a rocket 3. Manage to orbit Kerbin 4. Manage to do something “cool” 5. Repeat step 4 6. Watch other people play KSP
100. Let’s Play

102. Challenges 1. People self-issue or accept 3rd party challenges from the to community 2. Try and complete the challenge 3. Generally then show it off
