Generalization vs Specialization

  • Back to Work #209: Habitual Ritual
  • What causes some folks to collect hobbies/interests while others focus on and master one thing?
  • Opinion: Is It Better to Specialize or Generalize? - Nora Dunn (no, not the SNL Nora Dunn)
  • What type are we?
    • John
      • Restless. I like to learn a little bit about a lot of stuff.
      • I wish that I could learn a lot about a large number of things, but I don’t have the time nor the mental capacity.
      • I believe in the axiom that “Someone always knows more ‘Karate’” and that frustrates my efforts to go deep in any one area.
    • Chad
      • Cop-out. Somewhere in the middle.
    • Darryl
      • Generalist. I have always collected hobbies and dabbled in things superficially. This has transferred over to my professional life with two major (but complementary) career changes.
  • How does this serve us with regard to iOS development?
  • How has this hindered us?

Open-Source Project of the Week

  • DDAntennaLogger - Giovanni Lodi Giovanni asked what we thought of his simple remote logger. I was unfamiliar with both CocoaLumberjack and Antenna, so I’m passing the question along to our listeners. What do you folks think? Open up some issues/pull requests for Giovanni.

#54: Episode 54 - Who wants to support Android anyway?

The Discussion

SceneKit

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.

The Discussion

  • Time Estimation and Deadlines for development projects/tasks
    • What are your techniques? Are they effective/accurate?
    • Estimating with a team vs. by yourself
    • If you’re doing UI work (w/ or w/o a designer) vs. non-UI work
    • How often do you reassess your estimation?
    • When do you admit that your estimation is wrong or you won’t make your deadline?
    • How to prioritize tasks when a deadline is looming and not everything will get done?

  • SimPholders 2.0
    • A rewrite of simpholders in Swift.  A tool for viewing your iOS Simulator folders, the apps installed and what was recently run.  Great tool now that Simulators are unreadable GUIDs.

  • NSHipster (Nate Cook) - JavaScriptCore A deep dive into using JSContext and related classes to evaluate JavaScript on iOS. Among the many use cases for JavaScriptCore is game scripting (although LUA is perhaps a more popular solution), which may come in handy for a future episode of iOhYes.

The Discussion

  • The Open-Office Trap published in the New Yorker, by Maria Konnikova
    • 1997 - The University of Calgary study (before, 4 weeks after and 6 months after)
      • Disruptive, stressful, cumbersome, dissatisfied, resentful
      • Productivity fell
    • 2005 Study
      • When workers couldn’t change the way that things looked, adjust the lighting and temperature, or choose how to conduct meetings, spirits plummeted.
    • johnsextro This article sounds like a bunch of crying from a pretentious primadonna http://t.co/x3jDzAerwC
    • Types of open floor plans
      • the blank slate - just tables and chairs
      • moveable walls - rolling or sliding walls/whiteboards used to create separation
      • Team Area / Pit / Bullpen - semi-private partitions, not easily reconfigured
  • John’s opinions
    • Cubicles, they suck
      • False sense of privacy
      • They don’t contain nor block noise
      • They get in the way and are a waste of space
    • Offices, slight better but still bad
      • They can contain and block noise
      • But they are a terribly inefficient use of space
      • Stifling to collaboration and fascist
  • Darryl’s opinions (read: facts)
    • Open floor plans, they suck
      • Amusing article (http://verynicewebsite.net/2015/01/be-yourself-as-long-as-its-your-best-self/)
      • Workers are left with no sense of personal space as a company grows
      • The universally proposed “solution” to noise is headphones, read: OTHER NOISE
      • People feel free to interrupt your workflow in person, as if IM and email wasn’t bad enough
      • Note: I think this actually works well for teams up to 10 quiet people (no phone calls, etc), beyond that, it’s untenable
      • My favored compromise solution: Bullpen cubes (cubes that can accommodate teams of 4-5 people)
    • Cubicles, I hated them until I no longer had them
      • I miss my partitions
      • Cubes actually do affect noise levels: they discourage yelling across the room and deflect and diffuse/absorb audio a bit (when built properly)
    • Shared offices, I love ‘em
      • Office with up to 3 occupants
      • Can get cramped, but with good office-mates, it’s pretty harmonious
      • Especially good if your office mate is always going to meetings (and you aren’t)

  • 30th Annual International Technology and Persons with Disabilities Conference (#csun15, San Diego, March 2-6, 2015) As the name implies, this is a conference related to technology and how we make it accessible to those with disabilities. I’ll be attending for the first time. Traditionally web-heavy, there are a few iOS-specific sessions this year in addition to several sessions that are universally useful regardless of platform. Early-bird registration ($455) ends February 3, 2015
