You Don’t Need to Rewrite to Move Forward

The story you are about to read is mostly true. The names have been completely omitted to protect the innocent. It is extracted from the caffeine addled brain of an old-school software engineer. Take from it what lessons you wish.

As software engineers we always seem to want to rewrite something. There is an immense sense of freedom that comes from clicking: File –> New Project…

The next time you have the rewrite urge, think instead on how you can execute an incremental improvement to the code without rewriting. I would submit that if you think that a rewrite would be just ‘one step’ and ‘super easy’, it really isn’t. Factors, actors, capital, and time on a scale you never dreamed of will enter into your rewrite effort eventually.

Practical Get Started With Swift

Recently, I had to get started (fast) with Swift on a series of existing iOS projects. I would classify myself as being able to get to fourth gear in a Honda Accord with a manual transmission when it comes to using and applying Swift. I look forward to the day when my Swift knowledge is equivalent to running full out on the Nurburgring in a Bugati Veyron.

My background is C, C++, C#, Objective-C, with a side of JavaScript along the way.

I will never admit to any classic Visual Basic, or VB.NET, code ever being typed by my fingers, ever!

When it comes to learning a new language, I find myself in ‘Use it or lose it’ mode. Learning Swift comes very naturally if you have a concrete task which allows you to add a feature, or refactor an existing iOS project, with brand new Swift code.

I found that becoming proficient with Swift was very easy given the general C language progression in my career. In very short order, I was able to do almost all the tasks in Swift that I would normally do in Objective-C against the CocoaTouch / UIKit API surface. More advanced Swift language constructs exist, which I have barely touched, and hope to be able to learn and apply some day—I am looking at you, protocol extensions and generics.

Adding Amazon Alexa Voice Services to Your iOS App with Swift

Major thanks to the MacLexa project out on Github for providing motivation, source code, and a great starting place for this blog post.

Virtual Reality vs. Augmented Reality – Impact on Your Business

pexels-photo-166055

Virtual reality (VR) and augmented reality (AR) have come out of nowhere to become ‘the next big thing’.

With the failure of Google Glass as an augmented reality platform for consumers, the seeming success of the Oculus Rift as a gaming-based virtual reality platform, and the weird novelty of Microsoft HoloLens as a resurgence in the augmented reality realm, it can be hard to understand the scope, purpose, and worth of these new ‘worn on the head devices’.

Increase Local Reasoning with Stateless Architecture and Value Types

It is just another Thursday of adding features to your mobile app.

You have blasted through your task list by extending the current underlying object model + data retrieval code.

Your front-end native views are all coming together. The navigation between views and specific data loading is all good.

Git Commit. Git Push. The build pops out on HockeyApp. The Friday sprint review goes well. During the sprint review the product manager points out that full CRUD (Create, Read, Update, Delete) functionality is required in each of the added views. You only have the ‘R’ in ‘CRUD’ implemented. You look through your views, think it just can’t be that bad to add C, U and D, and commit to adding full CRUD to all the views by next Friday’s sprint review.

The weekend passes by, you come in on Monday and start going through all your views to add full CRUD. You update your first view with full CRUD; start navigating through your app; do some creates, updates, and deletes; and notice that all of those other views you added last week are just broken. Whole swaths of classes are sharing data you didn’t know was shared between them. Mutation to data in one view has unknown effects on the other views due to the shared references to data classes from your back-end object model.

Your commitment to having this all done by Friday is looking like a pipe-dream.

Practical Data Cleaning Using Stanford Named Entity Recognizer

I enjoy learning about all of the events in and around World War II, especially the Pacific theater.

I was reading the book Miracle at Midway  by Gordon W. Prange (et. al.) and started to get curious about the pre- and post- histories of all the naval vessels involved in the Battle of Midway.

Historically, so many people, plans, and materials had to merge together at a precise moment in time in order for the Battle of Midway to be fought where it was and realize its radical impact on the outcome of World War II.

I got curious as to the pre- and post-history of all the people and ships that fought at Midway and wanted a way to visualize all of that history in a mobile application.

Universal Windows Platform – The Undiscovered Country for Windows Desktop Apps

It is unfortunate, but I think Dr. McCoy from Star Trek: The Original Series said it best: ‘Windows 10 Mobile is dead, Jim“…. and just to pile on with one more.

Buried underneath the red shirt like death of Windows 10 Mobile lies the amazing Universal Windows Platform (UWP).

The developer capabilities of the Universal Windows Platform have been documented in many a location.

UWP provides:

  • Full developer parity at the API and framework level across all flavors of Windows 10, Xbox One, HoloLens, and Windows 10 Mobile devices.
  • A simplified install model via APPX bundles.
  • A per-app separation of registry and file systems.
  • XAML controls ‘just work’ across all Windows 10 / UWP devices.
  • Targeting the UWP API set ensures that your app works across Windows 10 / UWP devices.

In my experience, there is nothing weirder than seeing your Windows 10 / UWP app just work on an Xbox One,  in a virtual projected rectangle via a HoloLens, and via mouse and keyboard on a standard Windows 10 PC.

Mobile App Services

Starting on a mobile app can be a daunting proposition.

Your stakeholders at Rex’s Gym really need this app to help drive customer retention, promote the business, and make payments a breeze.

Getting the development environment set up, learning a new language, understanding a wholly different API for screen layouts per-platform, having to go to the Apple Store and buy a Mac (which is the absolutely last thing you thought you would ever do).

Apple WWDC – The Worth of Being There

In this era of travel budget crackdowns and higher than normal oversight into technology budgets, the iOS software engineer can get lost in the shuffle when it comes to training time and opportunities to talk with other members of the iOS development community.

Due to the rise of the popularity of Apple’s iOS platform, Apple WWDC (Worldwide Developer Conference) has become the central rallying point for iOS developers. It seems that the entire iOS community gathers in San Francisco over the week of WWDC. Many developers go to San Francisco over the week of WWDC even if they don’t have a ticket to the conference.

C# vs. Swift – Iron Man vs. Captain America

In Captain America: Civil War we get to see the ultimate battle between Iron Man and Captain America.

It is a battle of simple gutty defense vs. smart weapons and flashy offense, humility vs. brashness, down in the dirt vs. up in the clouds.

To totally geek it up, the same kind of battle exists in the languages that software engineers use today and I believe this is especially true in the battle of C# vs. Swift.

Don’t worry, this really isn’t a versus type write up. If anything I seek to point out each language’s unique strengths, then show how software engineers can get into the right superhero mindset to really use those strengths, and be aware of the weaknesses, to create great solutions.
