Enjoy reading and stay tuned!
Last week I was travelling the country talking to academics and students about the opportunity of building apps for Windows 8.
During the week I had a number of really interesting discussions, however on Friday I had a comment from one student, who simply believed Windows 8, was for touch devices only.
We got onto the topic of keyboard and mouse as I was presenting using a Lenovo thinkpad which supports both touch and keyboard and mouse. I was simply demonstrating Windows navigation via touch and then via keyboard and mouse during the presentation demos and the student in question seemed to be blown away by this and when we discussed this it more detail after the event he wasn't aware of the number of Windows Shortcut keys available.
So here a quick list of some of my favourites

One great thing about academia is that its always important to understand your skills, particular situation, objectives and what you are trying to achieve.
So thanks to Joel Citzen and his blog The following guidance will help you get started to being the most effective developer.
What type of developer are you?
New to the Platform Typically you would have no existing apps and can’t wait to build and ship your app to Windows Phone Store or Windows Store. In this case the suggestion is that as a beginner you grab the free tools and start exploring building for either platform. You can explore:
Seasoned in Windows Phone App You already built Windows Phone Apps and now want to build apps for Windows Phone 8 and Windows 8. You will find a lot of similarities when you develop your apps for both platforms. To get started explore:
Seasoned in Windows Store App You already built Windows Store apps and now want to build apps for Windows Phone 8 and Windows 8. You will find a lot of similarities when you develop your apps for both platforms. You can get started by exploring these sources:
Seasoned in another Platform You’ve built apps for other platforms, and want to ship them or port them to Windows Phone 8 and Windows 8. Many of the programming concepts will be familiar. Both platforms support C++, and the tools have templates to help you get started. To learn more explore:
Games Creator from another Platform You’ve built games for another platforms and want to port them to Windows Phone 8 and Windows 8. We’ve invested significantly in native gaming support on Windows Phone 8 and this will make it possible for you to port your existing games to both Windows Phone 8 and Windows 8. Check these resources:
Maximising Code Reuse.
After choosing your approach, based on what type of developer you fall under, you can now decide what choices to make to maximize code reuse in your apps. As a developer, you want to streamline your development and make maintaining your app efficient. When building an app for Windows Phone 8 and Windows 8, you should look for opportunities to share code, designs, and assets as much as possible so that you maximize the return on your investment.

Dare to be Digital is a video games development competition for extremely talented students at Universities and Colleges of Art.
Teams of 5 students, usually a mix of artists, programmers and audio, assemble at Abertay University for 9 weeks during June to August to develop a prototype video game, receiving mentoring from industry. The students also receive a weekly stipend of £150 per student, free accommodation at the University's halls of residence and a team budget of £200.
At the end of the competition, the prototypes are displayed at talent showcasing event Dare ProtoPlay. The general public and industry experts get to play and vote for the games. At the Dare awards ceremony, three prizes of £2500 will be awarded to the three highest scoring teams based on the criteria of innovation and creativity, market potential and use of technology (none of the three will be specifically attributed to any particular criterion). Seven months later the winning teams attend the BAFTA Video Games Awards to compete for the coveted "Ones to Watch Award".
Sounds good, yes? here are the benefits to student who take part:
Dare 2012 winners announced at Dare ProtoPlay
So on the 14th August 2012 The three BAFTA-nominated winners of Dare to be Digital were revealed at the climax of Dare ProtoPlay. Over the weekend a record-breaking audience of 10,000 people played the 15 games over three days at the free Dare ProtoPlay games festival in Dundee.
The three games who now compete for the exclusive BAFTA ‘Ones to Watch’ award at the 2013 BAFTA Video Games Awards are:
- Starcrossed, for Windows Phone 7 by Kind of a Big Deal (team leader Kimi Sulopuisto, Petri Liuska, Andrew MacLean, Minttu Meriläinen, Vili Viitaniemi)
- Pixel Story, for PC by Loan Wolf Games (team leader Martin Cosens, Luke Harrison, Ashley Hayes, Thomas McParland, Benjamin Rushton)
- Project Thanatos, for PC and virtual reality headset by Raptor Games (team leader Hugh Laird, Andrew Coles, Tom Kemp, Tom Laird, Alexandra Shapland)
Kimi Sulopuisto from Kind of a Big Deal said: “This is the biggest thing I’ve achieved in my life. I’d absolutely encourage anyone looking to make their own games to enter Dare to be Digital – you’ve nothing to lose, and you could win so much.”
Martin Cosens from Loan Wolf Games said: “This is absolutely amazing. For anyone wanting to make games, I’d say don’t hesitate, just do it. Don’t let anyone curb your ideas or hopes, as things like this can happen – you can get into Dare to be Digital, and get nominated for a BAFTA.”
Hugh Laird from Raptor Games said: “We were hoping and praying we’d get nominated for a BAFTA – it really justifies nine weeks of hard, hard work. And we didn’t expect to win the audience award, which is just the icing on top.”
Johnny Minkley, BAFTA Games Committee member and Dare judge, said: “I’m hugely impressed with the standard of all the games on show and the professionalism and passion of all the Dare to be Digital teams. “It was a hard choice for the judges, but all three BAFTA nominees are strong games and very different games. It will be a really tough decision for the judges to pick the final BAFTA winner at the Video Games Awards next March.”
Loan Wolf Games were also the winners of the brand new £25,000 Channel 4 prize. They will now be funded and supported to complete their game for a full commercial release.
Raptor Games also won the public vote for the Intel Visual Computing Tools Audience Award, with each team member receiving an Intel Ultrabook.
Kind of a Big Deal were supported to take part in Dare to be Digital by the Scottish Government as this year’s Nordic competitor, as were the Chinese and Indian teams.
Professor Louis Natanson, who leads computer games education at Abertay University, said: “The entrants to Abertay University’s Dare to be Digital get better and better every year, and all 15 teams have done something incredible – built a professional, playable and exciting game in just nine weeks. “The BAFTA-nominated winners – Kind of a Big Deal, Loan Wolf Games and Raptor Games – stood out from the tough competition for their exceptional game design, playability and commercial appeal, but all 15 teams have the experience now to enter the games industry or start their own businesses. “We look forward to seeing, and playing, many successes from them in the future.”
This year’s Dare ProtoPlay festival was also expanded to include Dare Indie Fest, a conference for budding entrepreneurs and a showcase of games from independent companies.
Dare Indie Fest was presented by the Abertay Prototype Fund, which provides grants of up to £25,000 to small and startup games companies. Over 40 games were available to play for free throughout the Dare ProtoPlay weekend, including the 15 student games and new titles from independent game developers from across the UK and as far afield as Romania. Continued Scottish Government support of £85,700 enabled teams from China, India and Finland to take part in Dare to be Digital this year. Cabinet Secretary for Culture and External Affairs Fiona Hyslop officially opened the Dare ProtoPlay festival on Friday. Support from EventScotland enabled Dare to be Digital to expand into the City Square marquee. The event was also supported by Ukie, Dundee City Council and Interactive Tayside.
I am pleased to announce that the Winning Game - Starcrossed, for Windows Phone 7 by Kind of a Big Deal (team leader Kimi Sulopuisto, Petri Liuska, Andrew MacLean, Minttu Meriläinen, Vili Viitaniemi) is now live in the Windows MarketPlace achieving a NEW Record. Ensuring their app was published into the commercial marketplace – via the Windows Phone Marketplace in the shortest time after Dare.
Starcrossed is a whimsical 2D platformer game where you guide a crash-landed astronaut back to his home planet, using a rocket launcher to send him flying through space from one asteroid to another. Gravity plays a pivotal role as it will affect the astronaut’s movement. Temperature is also important: be careful not to expose the astronaut to the burning heat of the sun or the freezing conditions of outer space for too long!
Starcrossed was created during the Dare to be Digital 2012 games development competition. The game was one of the winning entries and is nominated for BAFTA "Ones to Watch" award 2013.Features:- Intuitive one-touch controls- 30 levels of fast and quirky gravity-based gameplay- Various different planets, each with their unique properties- Vivid colours and a painterly look- Original sound and music Watch the game trailer at: http://youtu.be/VSUO5dtWnx8 Follow the team at: www.facebook.com/starcrossedgame www.facebook.com/koabd2012 www.twitter.com/koabd2012 Find their publisher at: www.facebook.com/kajakgames and www.twitter.com/kajakgames
Watch out for our guest blog from Kimu Sulopuisto from Starcrossed tomorrow, where he will discuss Starcrossed and his experience of Dare and Windows Phone 7 and what a Kind of a Big Deal achieved from the event.

Last week a student at the University of York asked me about my views on typescript.
So what is Typescript
Microsoft Technical Fellow Anders Hejlsberg states that. TypeScript is designed to add those extra bits, with static typing and classes at the top of Hejlsberg's list of developer desirables.
So how is Typescript being used, TouchDevelop is a novel, touch-first IDE originally written as a Windows Phone 7 app using C# and XAML.
For more details on Touch Develop Development see the following //build session. http://channel9.msdn.com/Events/Build/2012/3-018
Typescript site http://www.typescriptlang.org/
New feature now available in Microsoft TouchDevelop, the mobile programming environment.
TouchDevelop Web App Preview at touchdevelop.com/app runs on
For Windows Phone 7/8 you can get the fully featured app in the Windows Phone Store that can access even more sensors and data.
We have quite some fun testing the latest TouchDevelop releases on many different devices…
TouchDevelop lets you create and run apps on pretty much any modern computing device you might own from smartphones to tablets and even PCs. TouchDevelop features a predictive on-screen code keyboard and a touch-optimized programming language.
Having been designed for mobile devices from the ground up, TouchDevelop is an excellent option for programming on touchscreen devices without keyboards. You can also use it with a traditional keyboard and mouse if your device supports them.
After you have designed your fun game or a useful tool, you can share it with other people with a single tap or mouse click, so that they can run it or tweak it. More than 12,000 scripts have already been shared with over 40,000 users who have signed in to the TouchDevelop experience.
TouchDevelop is also an excellent option for learning programming.
The high-level programming languages makes it super easy to create simple apps. But TouchDevelop is not just for beginners – for more complicated tasks only sky is the limit, thanks to the underlying powerful language and extensive library support.
If the TouchDevelop environment is not enough, you can export true apps and submit them to the Windows Store or the Windows Phone Store to start earning money and building a portfolio
Start coding with the Web App in your browser at touchdevelop.com/app or get the Windows Phone app.

I recently took part in a Microsoft Partners in Learning Virtual University series on TouchDevelop delivered by Jonathan 'Peli' de Halleux who works for Microsoft Research in Redmond, WA. The series was part of a PIL Appathon Competition for educators around Europe, the final stage of which will be a 24 hour Appathon in London just before BETT in January 2013. I had no idea what to expect from the series and had no idea about what TouchDevelop was. The series was excellent and I know have a firm understanding of the fundamentals of TouchDevelop and how to create simple apps using it. It was also a fantastic experience to be part of a community of learners from around Europe sharing experiences during online sessions and via PIL network forums.
I teach Games Development at Reid Kerr College in Paisley, Scotland and I currently mainly use XNA with C#; however we have been looking at different tools to introduce students to programming such as Scratch, Kodu and MIT App Inventor, as XNA can be quite a jump for students who have never programming before. We are also keen to get students creating APPs and after learning about TouchDevelop I think it is a great platform to achieve these goals.
The really big difference about TouchDevelop and other dev tools is that it allows you to actually code and test your APP on a mobile device. You can choose to develop on a PC and then package it as an APP, but you can code on any device which has a modern HTML5 browser. So if your device can run IE10 or the latest versions of Safari or Chrome, you will be able to use TouchDevelop to code and test APPs on your device. I have used a variety of platforms successfully with TouchDevelop; on desktop PCs I have used IE10 in Windows 8 and Chrome in Windows 7. I have also used Safari on both the iPhone and iPad and on my Windows 7 phone I have used the dedicated TouchDevelop APP. So although TouchDevelop only creates APPs for the Windows Marketplace on WP7/8 and Windows 8, you can develop and test APPs via the TouchDevelop site on your favourite browser on pretty much any device.
Coding with TouchDevelop on iPhone
Another great part of TouchDevelop is the community aspect to it. The scripts (APPs) you publish are available to the rest of the community to use and play, which means if you don’t know how to do something you can look up someone else’s script doing a similar task and you will quickly find the solution. You can also take other user’s scripts and alter them and credit is still given to the original publisher as it shows how many variations of your scripts are out there. You can also build libraries yourself and then these libraries can be used by other users when creating their own apps and once again you can see how many scripts are using your library. One other great feature of TouchDevelop is the ability to have a high score table which the community can immediately contribute to as soon as you hit the publish button from your script. This is not publishing it as an app on the marketplace it is just making it available for the community to try out and it only takes 2 or 3 lines of code.
High Score Table
TouchDevelop comes with a variety of libraries which makes most tasks easy to do. I have been working a lot with the game board, which has built in functions for dealing with sprites, collisions, physics and touch events.
Pong created in TouchDevelop
Once I got used to working with the interface and the language I was able to quickly put together some games. I created a touch version of PONG in about 2 to 3 hours, in which you use your finger to control a Bat by sliding your finger up & down to try and defeat an AI controlled Bat. I also created a Space Invaders clone called TouchInvaders which took me roughly about 4 hours to get a working version, although I did go back later and tweak it to add shields and play about with the controls.
TouchInvaders on iPhone
TouchInvaders running in Chrome on a Windows7 PC
TouchInvaders running in IE10 desktop browser on a Windows 8 PC
TouchInvaders running in IE10 on a Windows 8 PC
TouchDevelop is still in its infancy and therefore has a number of minor bugs, but the Microsoft team are constantly working on these and improving it and adding functionality on almost a daily basis. Overall I would say that TouchDevelop has amazing potential and is a good alternative to some of the other tools out there that can be used to teach programming at a beginner’s level, however unlike Scratch it actually allows you to make games I would want to play.
