2019 360iDev Conference Day 2

The conference kicked off at 9:30 a.m. on the 2nd floor of the Grand Hyatt.

The conference uses a 3rd party app http://www.essemble.us/ for scheduling of the conference.  I found it very useful to know session information, times and location.

Think outside yourself

If you’re building something, test it with folks who experience life differently from yourself.

Think about times where you or someone you know has struggled to find or access something important.

I am here today because people saw the potential in me and gave me a chance. If you are in a position to do so then do it.

Think Different

Autism is a neurologic condition. It is an inability to cope with sensory input. Everyone hearted the support dog.

Do we have financial incentives to behave bad?

We social allow bad behavior. Which rules do we all to break?

  • Changing or maintaining a day
  • Don’t Selectivity enforce rules
  • Eliminate Sensory Distractions
  • Make user Stories as detailed as possible

Build immersive experiences with ARKit and CoreLocation



2019 360iDev Conference Day 1

I left Omaha airport to in Denver on Saturday night. I took the rail car from the Denver airport to downtown Union Station.

I then walked to the Grand Hyatt Denver Hotel. Which was about 20 minutes.

Pre-Conference Lab

Generic Swift. It isn’t Supposed to Hurt

Taught by Rob Napier



This was a live coding workshop using playgrounds. Opening statement

“Write the most concrete implementation before a protocol.”


  • Real Life Protocol
  • Codeable gives me certain power
  • Protocols don’t conform to itself like a class when inheriting.
  • Type signature can be a parameter in func
  • Retroactive Modeling
  • When I use a class it is because I need a reference type not to do inheritance.
  • Classes have a meaning.
  • Any value type should have a equateable.
  • SwiftUI uses data in background.
  • You can turn any result into a throwing method.
  • If you put a static method on a protocol then it is inherited by other protocols.
  • Reference semantics
  • Typing a name of a Protocol represents protocol.
  • Single value containers
  • Typealias
  • phantom type.
  • TypeEraser get ride of type information

Everything you know is about to change




  • Declarative
  • Automatic
  • Compositional
  • Consistent
  • One framework for all devices. The views will need to change
  • No matter InterfaceBuilder or AutoLayout
  • Better ways to build programmatic views.
  • SwiftUI will handle the Declarative View.
  • Composition over Inheritance
  • The views are collapsing down. A view returns only one.
  • Font’s and colors return a view
  • Property Wrappers
  • All property values to be wrapped by various types.
  • @State: is a property Wrapper. When state updates, the property redraws.
  • A new view is a VStack
  • Containers
  • HStack
  • Trailing Closure Syntax
  • @ViewBuilder is a property wrapper.’
  • Ten View Limitation is a complier errors when more than 10.
  • Migrating from UIKit to SwiftUI


I did not attend this workshop, but found the slides fascinating.

Blockchain Development Group: Libra

This evening I attended the Blockchain Development Group  hosted by Farm  Credit Services of America.

Started with networking and Pizza.



Tonight’s talk was on Libra by Kyle tut of pinata.cloud.


Libra validator nodes are responsible for validating transactions. Experimenting with node validators.

Developed as a smart contract language. Learned from solidity. Integration will be done through modules. The 2/3 majority will need to approve.The main goal of Libra is to be stable. They have not solved problems with Ethereum.

Calibra is own by Facebook. It is a digital wallet. It is also a partner.

Re-seller takes money and puts into the Reserve. Then money in exchange will be put in Libra. Not much different then a global ACH network. The goal is about controlling where the amount is stored.

There will be regulatory considerations. If successful won’t have to deal with regulations as other financial transactions are. Libra is a digital currency not a crypto concurrency.

Google Developer Group Omaha: Intro to Flutter

This evening I attended the Google Developer group hosted by CRI at the Travel and Transport building.

trave and transport

Started with Introductions: Such as I am Anthony Carlson. I am the Lead Application Developer at Farm Credit Services of America with emphasis on the iOS and Android platform.

Intro to Flutter

Tonight’s topic was on Flutter. An intro to Flutter and Getting a Flutter app to production were the topics. Flutter works as a plugin in Android Studio. You can connect to the iOS simulator.

  • Portable UI toolkit
  • Native Mobile or Web
  • State Management
  • Compiles to native file

App built is a Tree structure. Everything is a widget. There is also a process for developing a package and plugins. Scaffolding is very similar to material design. When you develop you are acting in a state. Let flutter manage state. The more complex or nest widgets is when state management.

It was a brief talk, but educational.

Azure May Meeting

I attended my first Azure meeting at the Microsoft building in Aksarben.

The group meets last Wednesday of the month at 3:00 p.m.

The topic was on Microsoft’s Azure Service Fabric is the PaaS (Platform as a Service) offering for service-oriented systems. By leveraging the same platform Microsoft uses to build their own services (such as Azure SQL Database and Azure Cosmos DB), developers have access to a wide range of tools to improve scalability, reliability, and management of their microservices systems.

In this talk, Sr. Software Architect Andy Unterseher will explain what Service Fabric is, how it is hosted in Azure, which types of applications are best suited for it, and some situations where it may not be appropriate. Using a live application, Andy will demonstrate how to develop with Service Fabric and show how to deploy it from Azure DevOps. He will compare Service Fabric to other platforms (like Kubernetes) and talk about the still-in-preview Azure Service Fabric Mesh.


Hosting Services in Azure

I heard the term of iDesign which was talked at a topic at another meetup.
Function Apps
API Management
Can deploy asp.net core and api’s into the service fabric.

State Management

Development Strategy
Two Solution
• Locally
• Azure

Should your solution know about Service Fabric?

Updates create a package of differential when updating.

Azure Devops
Template vs Yml file.

What does Service Fabric do?
Allows to host legacy code and docker. Recommendation is not to.

What is the different in Mesh?
Mesh is container based?

Fully Managed
Deploy across availability zones

AIM IT Leadership Academy: Graduation


About 4:00 p.m. after the AIM IT Leadership Academy: Reality Based Leadership Session every was escorted to the atrium where we will meet any guests that will be coming. My accountability buddy along with other teammates from Farm Credit Services of America were down there waiting.  There were free drinks and light appetizers from Upstream Brewery served.

At about 4:20 p.m. everyone was ushered into the auditorium for a graduation ceremony.

Each member of the graduation class was called up one at time to say a few words. I was given a triangle plaque with my name and graduation class.

I spoke about being thankful for the opportunity to be in the program. I also mentioned how the interacting with different members in the capstone cup was eye opening to how other companies work.



AIM IT Leadership Academy: Reality Based Leadership Session

On Friday May 3rd the last AIM IT Leadership session was held at Omaha Public Power District located at in downtown Omaha  at the Energy Plaza at 444 So. 16th Street.

This session was on Reality-Based Leadership.  This is based on research and book by Cy Wakeman. This is a local speaker who wrote a book on the topic.

The principles of Reality-Based Leadership include:

  • Refusing to argue with reality
  • Valuing action over opinion
  • Leading first, managing second
  • Bulletproofing employees so that they can succeed, regardless of the circumstances
  • Working to be happy rather than to be right


The speaker for the day taking us through the course was Alex Dorr.


He started off with saying “I want to Thank you for being here and the opportunity to speak”

Here is a link to my notes along with the power point.

I can say this was my favorite speaker and session.

These were my three actions I took from the course today.

  1. Work on my personal happiness.
  2. Help others be accountable.
  3. Finding what great looks like at work.
