A good friend of mine was experiencing an issue with accessing the online features of Halo 5, and from doing a bit of googling, it appears he’s not the only one.
The error he was getting was:
Error Authorizing user with Halo 5: Guardians services. You will be unable to access online modes.
We did manage to fix the issue however… Continue reading “Fixed – Error Authorizing user with Halo 5: Guardians services”
One of the rules of using MVVM is that your model shouldn’t need to know anything about the UI Layer, and your View should be decoupled from the Model via the ViewModel. It can often be necessary to have some form of conversion between what our Model understands and what the View would understand. A common example would be converting a boolean flag to a Visibility State, this is where Value Converters come in.
We’ll follow a slightly more domain specific example in this case, converting the TranslationDirection Enumeration Property to a Visibility State for our Morse Input User Control.

Honesty is the best policy…
…unequivocally. Trying to cover something up simply doesn’t work. Everyone makes mistakes, even your boss, and if they’re worth working for, they’ll know that.
As the lead you should be the first to admit when you:
- are not going to make a deadline;
- did something silly that broke the build;
- are wrong;
- simply don’t know the answer to a question.
The last one is really important.

Coming predominantly from a .NET background (as you may have guessed) this was obviously quite a shift. Continue reading “Review : Write Modern Web Apps with the MEAN Stack by Jeff Dickey”
Pragmatism – Take your time
I’m sure you’ll have heard the saying :
Rome wasn’t built in a day…
…and it’s fair to say that 99% of the time, neither will your app be. Be realistic regarding what you can achieve and by when. Everything about the Agile methodology points to being able to work sustainably, and getting better at doing so along the way. There’s many articles about picking a vertical stripe or horizontal stripes through your architecture and delivering a concise set of functionality. My advice would be, don’t let your chosen stripe get too fat. If you can’t hit an imposed deadline, be honest and say ‘no’.

Despite the rise in popularity of Single Page Applications (SPAs) and supporting frameworks like Angular in the Web Development world, it might be nice if we had more than one page in our app, or at least had the option to. Our app so far is contained within a single page, MainPage.xaml. A common pattern is to have different pages for Settings or Publisher contact information. Navigation has moved on since Windows Phone 7.5 when it was URI based, we will look at how it now works with Universal Apps with typing and the MVVM Light implementation of INavigationService.

One of the most important skills in leadership, is knowing how and when to say ‘no’. It might sound trivial but it’s really far from it. There’s an excellent chapter in The Clean Coder by Uncle Bob Martin. I was fortunate enough to read this prior to having been put in a situation where I needed to say no and I found it invaluable in hindsight, would highly recommend.
As a fresh Lead you will no doubt have a number of challenges in managing client expectations, and at points they will inevitably ask too much of both you and your team. It’s times like these when you will gain the respect of the client for your honesty and integrity and the gratitude of your team for not putting them in awkward situations.
It’s easy to say yes, don’t fall into that trap, but just remember there’s a right way to do it. Continue reading “Development Team Leadership : First Steps Part 5”
As we saw when we migrated our Universal Windows App to Windows 10 targetting Phones and PCs with the same set of markup presents us with a challenge…
This UI is less than usable! There are a new set of User Controls made available as part of Windows 10, for example the Relative Panel. In this post we’ll look at ways we can make our UI adaptive based on the screen size we are targeting.
By the end of this post we will have a single app that is usable on PCs, tablets, and Phones. We’ll be looking into Visual State Triggers in order to alter the size of the text presented in our Input and Output TextBox and TextBlock controls. Visual State Triggers apply transformations to the base XAML defined, we’ll be using this method to make our app responsive.
Don’t be afraid to tackle situations that will push you out of your comfort zone, you’ll always be better for it. If you’re :
- nervous about a presentation, do it;
- putting off an awkward conversation, have it;
- unfamiliar with a technology, learn it.
…you get the picture.
There are of course limits, be sensible. Start small, Rome wasn’t built in a day and so on, but each time you tackle something new your horizon has expanded slightly, you’ll be unstoppable. Have confidence.

I’m sure you’re probably all aware that Windows 10 is out, (if not in the news then the nagging to upgrade), I recently took the plunge and upgraded my PC and tablet and have to say I’m rather impressed. Along with the Operating System I also upgraded my development environment to Visual Studio 2015 Community to start taking a look at Windows 10 Apps, (and maybe start dabbling in Xamarin now that it’s so accessible). In light of this, now seems as good a time as any to start looking at implementing our Morse Coder App as a Windows 10 Universal App.
Windows 10 Universal Apps differ from Windows 8.1 and Windows Phone 8.1 apps in that they require only a single Project for the UI, where the 8.1 apps would have had Windows, Windows Phone, and a Shared Project; Windows 10 requires only a single project. By the end of this post we should have a functioning Windows 10 app, with all the current functionality from the existing Desktop Version, running on both the Phone Emulator and the Desktop (and everything in between).
