Tech Douchebags #45: The Privileged Consumer

February 1, 2015 at 1:15PM • 1 hour 26 minutes

In this week’s meeting, Dan Benjamin of 5by5 works through step five by sharing his high expectations in being able to watch content whenever & wherever he wants, how he has the luxury to pay to remove annoyances with media consumption, why it spurs his growing attitude of entitlement, but admit that these are indeed privileged problems to have.

In addition, we discuss the fears of updating iPhone apps right away, paranoia with products and services tracking your location, ad relevance versus intrusiveness, ad retargeting, and the podcasting "renaissance".

Hosted by Jordan Cooper.

The Changelog #139: The Rise of io.js with Mikeal Rogers

January 30, 2015 at 5:00PM • 1 hour 2 minutes

Our guest this week is Mikeal Rogers, one of the leads behind io.js, a friendly fork of Node.js with an open governance model.

We discuss why the io.js fork exists, why they choose open governance, the roadmap and future of io.js, supporting ES6, burnout while working in open source, and the steps you can take to get involved with io.js.


41:54 - "One thing I figured out, and that this project continues to prove, is that it's not just about what you do, it's about what you don't do, and when you step away." - Mikeal Rogers

52:02 - "My next task is to jump into the roadmap repo, and figure out more ways of pulling in feedback from the community, and figuring out what people want out of Node next, and that's the direction I expect it to go in." - Mikeal Rogers

Hosted by Adam Stacoviak & Jerod Santo.

Diagnostics & Usage #2: Prime Presents: Bezos and Busey

January 30, 2015 at 4:00PM • 50 minutes

The Web Ahead #94: Rethinking Microsoft's Browser with Rey Bango

January 30, 2015 at 4:00PM • 1 hour 23 minutes

Microsoft announced that they will be introducing a new browser, codenamed Project Spartan. Windows 10 will ship with both IE and Project Spartan, but Spartan is the future. What is happening? How is it that the oldest popular browser is going to end? Rey Bango joins Jen Simmons to tell all.

The Discussion


For a discussion of Apple’s Metal Framework, see Episode 44

Here you go, Ilea, this one’s for you…

  • What is SceneKit?
    • Objective-C framework for building apps and games that use 3D graphics
    • High-performance rendering engine
    • High-level, descriptive API
    • Supports animation based on the Core Animation framework with defined animatable properties
    • Abstracts away the rendering algorithms used to display a scene, meaning you don’t need to worry about things like:
      • Object ordering
      • Culling
      • Shaders (though you can write your own if you like)
  • What is SceneKit not?
    • A game engine (you must provide your own logic)
    • An escape from linear algebra
    • Cross-platform (but who wants to support Android anyway?)
    • A fully-featured substitute for solutions like Unity3D
  • Why use SceneKit?
    • Very easy way to get your feet wet with 3D graphics
    • Suitable for simple games
    • Rapid implementation of visualization apps
  • Major features
    • Available on Mac OS X and iOS
    • Integrated inspection (model viewer, material editor, particle editor) and debugging in Xcode
    • COLLADA importing
    • Supports geometries, materials, lights and cameras
    • Animatable properties
    • LoD substitution (level-of-detail, allowing for variable geometry complexity)
    • Actions (allows for animation triggers, sound effects, etc)
    • Skinning and Deformations
    • Static/dynamic shadowing
    • Physics, including joints and inverse kinematics
    • Particles
    • Ray casting/hit testing
    • Custom OpenGL shader programs
    • JavaScriptCore bridging
    • SpriteKit overlays for performant 2D UI elements that don’t require an additional compositing pass
  • The basics (iOS-specific)
    • Assets are contained within a Scene Assets container in your Xcode project
    • Xcode performs optimizations at build-time (up-axis correction, vertex interleaving, PVRTC image format favoring, etc)
    • Scenes can be imported from COLLADA (in Xcode. The dae file is converted to a bplist [retaining the .dae extension] before it is put on the device) or un-archived from plists.
    • Scenes consist of a graph of nodes.
      • Root node: defines the world’s coordinate space
      • sub-Nodes: populate the world with visible content by attaching:
        • Cameras
        • Lights
        • Geometries
    • Scenes can be built-up (or modified after load) programmatically.
    • sub-Nodes from other scenes can be added to a scene, but a root node must not be added to another scene.
    • Important classes
      • SCNView - a view that displays SceneKit content
      • SCNScene - The container for all SceneKit content
      • SCNNode - The basic building block of a scene
      • SCNGeometry - A three-dimensional object that can be attached to a node. Also known as a mesh or model. SceneKit has several built-in primitives that can be used, or custom meshes can be imported or built from vertex data. Surface appearance is defined by materials attached to the geometry.
      • SCNMaterial - A reusable definition of surface appearance properties for an object
      • SCNLight - A light source that can be attached to a node, providing shading in the rendered scene
      • SCNCamera - A virtual camera that can be attached to a node, providing a point of view for rendering a scene.

Open-Source Project of the Week

  • iOS-8-SceneKit-Globe-Test - @schwa iOS 8 Scene Kit (swift!) project showing a spinning (earth) globe with diffuse, ambient, specular and normal materials. Also cloud layer. Yum.
