Microsoft Project Siena, create Windows 8.x app without any programming

Microsoft Project Siena

Microsoft Project Siena (code name) is the beta release of a new technology for business experts, business analysts, consultants and other app imagineers. Now, without any programming, you can create powerful apps for the device-first and cloud-connected world, with the potential to transform today’s business processes.

• Apps to explore media-rich product catalogs and create ensembles that together serve a customer’s needs
• Apps used on the spot to resolve customer service bottlenecks and logistics exceptions, with the custom intelligence to help the user make local trade-offs
• Apps for auditing and inspecting a manufacturing facility through photos, videos and pen and voice notes, all tied to an asset database

Siena apps are as easy as editing a document. You place some visuals on a canvas. You hook them up to your data. You customize how your app looks and works. Then, if you need special logic and intelligence, you write some Excel-like expressions. You can use your app immediately, or share it with colleagues or the world.

With Siena, you can conceptualize, validate and build your app ideas almost as fast as you can come up with them. And if your needs change tomorrow, updating your app is no problem. Open it. Change it. Share it again, and you’re off to do business.

Siena works well with corporate and web data and media content: SharePoint lists, Excel and Azure tables, RSS feeds and the gamut of RESTful services.

Siena apps are just HTML5 and JavaScript and are deployed and managed like any other Windows 8.x app. In fact, developers can open them up, see what’s there and, if needed, extend them in their favorite programming tools.

Install Siena, watch one of the how-to videos at http://aka.ms/ProjectSiena, and then build the app that you’ve been imagining... in under an hour.

• Conceptualize, validate and build your app ideas as easily as editing a document
• Connect to corporate and web data
• Compose rich interactive visuals to create custom, unique apps
• Add business logic and intelligence using the power of Excel-like expressions
• Use the app yourself, share with colleagues or with the world

Releasing HTML5 Games for Windows 8

Releasing HTML5 Games for Windows 8

Windows 8 presents an incredible opportunity for distributing and monetizing HTML5 games, and this guide shows how you can profit from it. You’ll learn everything you need to know about porting your original web-based JavaScript game to the new "touch-first" version of Windows, as well as several options for selling your game in Windows Store.

Windows 8 is a big leap forward for developers because it treats HTML5 as a first-class citizen, alongside C# and C++. Interactive development expert Jesse Freeman explains how Windows 8 works, gets you started with Visual Studio Express (it’s free!), and uses a case study to show you how to port an HTML5 game with ease.

• Learn which games and JavaScript libraries work best on Windows 8
• Adjust artwork for different screen resolutions and Windows 8 features
• Accommodate mouse, keyboard, touch, and other game controls
• Optimize your game to run well on any Windows 8 device
• Understand the steps for publishing your game to Windows Store
• Explore fixed price, trial mode, ad support, and in-app purchase options
• Use a web-first workflow to ensure your game runs on many other platforms

Emulation in Chrome DevTools

You can now realistically emulate many device characteristics on desktop, saving you time and making your iteration loop much faster. You can emulate screen size, devicePixelRatio, and ❮meta viewport❯ with full touch event simulation. More at http://html5rocks.com/en/tutorials/developertools/mobile/

 var my_var;
 console.log("use var after declaration: " + my_var);
 
 local_var = "Hello World";
 console.log("use var after value assigned: " + my_var);
 
 console.log("Un-declared var: " + another_var);
