Cross-platform UI Coup: Xamarin.Forms

One of the biggest problems with C# mobile development, platform-specific UI, is solved with Xamarin 3.
The greatest foe we face in our quest for cross-platform implementation is platform-specific code.  Code that is platform-specific must be implemented differently depending on the platform, whether iOS , Android, or Windows Phone.  Cross-platform patterns are the same regardless of operating system.  Cross-platform code is sometimes referred to as shared code, or core code, as it is shared between projects for different mobile operating systems. Certain types of code lend themselves well to cross-platform sharing …

Managing Mobile in the Workplace

We bring our phones to work now and use them for everything.  Facebook, Candy Crush, and Twitter are a great use of a smartphone but these devices are also helping us become more productive: email, file and document handling and editing, as well as contacts, calendars and integration with sales, financial, and other third-party business apps.  This creates two things:  opportunity and challenge.  We want to seize upon the opportunity of best utilizing these devices to do our jobs while addressing the challenge of the resulting exposure of company data …

Responsive Design and Why Customers Expect It

We take this for granted now but there is an important historical fact in the development of websites and web applications:  They were originally designed for use on desktop PC monitors and laptops. The design of the website accounted for the size of the screen and the user interface (a mouse).   So why do our apps and website need a different design today? Because people are fleeing in droves from desktop PC browsers and using their mobile phone for internet use instead.  The older design accounted for the user making …

Coding, testing, and releasing at breakneck speed.
What could go wrong?
Technical Debt
Constant changes to a system lead to disorganized code, which is fragile and costly to maintain.  Each feature we add without spending an equal amount of time reorganizing the code accrues some measure of technical debt.  Agile’s fast pace and change-orientation raises the risk of bringing about the early demise of a system through this process.   So how do we pay off that debt before it accrues?
The lifecycle of software is well-established: Enhance the code until it becomes unmaintainable, then …

Responsive Design for Sharepoint

I recently spoke at SharePoint and .NET Saturday Bermuda,  a one day conference co-hosted by the Bermuda SharePoint Users Group and the Bermuda .NET Users Group. The keynote by Joel Oleson focused on the trends of mobile and tablet use in the enterprise, and ways that Sharepoint development addresses this trend. Responsive Design is the order of the day.  Enterprise web applications must be constructed in a flexible, adaptive manner that detects and responds to the device type.  That is, the web pages should look different and display appropriately different content depending on whether they’re …

When it comes to native mobile development, .NET shops are in a pickle.    Mobile and tablet use is estimated to make up 90% of new device adoption by 2015 (Gartner).  Steve Jobs saw this coming and had this to say:
“When we were an agrarian nation, all cars were trucks, because that’s what you needed on the farm, but as vehicles started to be used in the urban centers, cars got more popular.

The Agile/XP notions of frequent releases and constant redesign can be worrying.  There was a day, not far in the past, that code changes, any code changes, struck fear into the heart of a developer or project manager.  In many cases this fear was justified.  The majority of code was quite brittle and fragile.  The smallest of changes could bring an application to a grinding halt.   That’s why, when we’re doing things the Agile/XP way, we use Test-driven Development(TDD).   As we destabilize the code with refactoring and destabilize …
