3. Speed kills! In 1830 people thought, your brain
stops working travelling more than
20 mph. And anyone going at more
than 30 mph would have all air
sucked out of them and would
suffocate to death.

2 million new sensors will be deployed

6. Regular Users don’t Rule the Tech!
Today's Smart Home solutions are
not good enough for a mainstream
market. These solutions are well
suited to early adopters, but have so
far failed to attract mainstream
buyers. (see VisionMobile “The Smart
Home Landscape 2015”)
Progressive Thinkers Worriers
Antagonists

25. Minecraft Forge: Simple Modding
Bare minimum
Get the Minecraft Forge Mod Development Kit (MDK) from http://files.minecraftforge.net/

26. Java and Minecraft Forge: Setup and Lifecycle
@Mod(modid = SmartHomeMod.MODID, version = SmartHomeMod.VERSION)
public class SmartHomeMod {
public static final String MODID = "smarthomemod";
public static final String VERSION = "0.1";
// Happens as #1 right before Minecraft loads. Used for most registration.
@EventHandler
public void preInit(FMLPreInitializationEvent event) {}
// Happens as #2 when Minecraft loads.
@EventHandler
public void init(FMLInitializationEvent event) {}
// Happens #3 when World generators and alike are loaded.
@EventHandler
public void postInit(FMLPostInitializationEvent event) {}
// Happens #4 right before starting the server.
@EventHandler
public void registerCommands(FMLServerStartingEvent event) {}

27. Use SmartHome Plug-In via SSE and REST API
• List of Things via HTTP Get
http://localhost:9998/rest/things
• Server Sent Events (SSE)
http://localhost:9998/rest/events
• Helps to check what’s possible and
what’s going on
• Player
• Switches
• Doors
• Sensor
• …
• Unique ID is always location
• Relevant data is separated into
components (channels)

29. Minecraft Spigot: Simple Plug-in
Bare minimum
Get the Minecraft Spigot Server, API, and Build Tools from https://www.spigotmc.org/wiki/buildtools

30. Minecraft Spigot: SmartHome.java
public class SmartHome extends JavaPlugin {
// Fired when plugin is first enabled
@Override
public void onEnable() {
// Register event listener
// Could handle PlayerJoinEvent, BlockRedstoneEvent, PlayerInteractEvent, BlockPlaceEvent...
// ...using @EventHandler annotation
Bukkit.getPluginManager().registerEvents(new BlockChangedListener(), this);
// Register command (set an instance of command class as executor)
this.getCommand("sendCommand").setExecutor(new SendCommand());
}
// Fired when plugin is disabled
@Override
public void onDisable() {
}

38. Businesses are coming to realize that attracting
developers is the fastest route to innovation.
Moreover, attracting developers means
attracting external investment, which finances
innovation and expansion.

MYTHSOFTYPICAL DEVELOPER /BORNTOCODE
Innovation Prosumer: Consumer and Producer
Millions and millions of dollars are being spent
to attract developers: The millions of dollars in
developer marketing efforts serve one purpose:
to persuade developers to use a specific
platform, network, tool or API set to generate
innovations and to reach more consumers. In
short: Developers consume an Platform, API,
etc. and produce something based on it.
