24 Weeks of Windows Phone Metro Design | Touch Targets

AddThis Social Bookmark Button
source: In a touch device you use your finger or fingers to interact with UI controls on the screen. Our fingers are chubby in general J so if we present UI objects that are too tiny, it will be hard for users to target these. So the following guidelines give you some ideas for how to avoid user frustration and ensure UI objects on the screen are accessible and touchable by users. The minimum recommended touch target is 9 millimeters. Giving you millimeters might only take you so far since we all use
pixels when it comes to designing a screen UI. I usually use 9 pixels as the reference. When you really need to have tiny elements you can go down to 7mm (around 7px) Now, one thing is the touchable area and another is the visual size of the item. The minimum size for a touchable item is 4.5mm (some 5 pixels). So you could have a tiny elements of 5 pixels but with a touchable area of 9 pixels around it. ...Read more ...(Read whole news on source site)

Feature dependencies chains

I wanted to improve the RavenDB query optimizer, so it can merge similar indexes into a single index. It is actually fairly simple to do (conceptually). But that leaves us with the problem of what to do with the indexes that we just superseded. The whole point here is to reduce the number of indexes, not to create an index that will never be used. So the next step was to make sure that we can cleanup unused auto indexes. That is great… Except that we don’t have any way of tracking unused indexes, so before we could do that,
we have to add tracking for query times. Okay, let us do that. Wait, we don’t have a place to put those in, and anyway, we don’t want to save it all the time, that would mean IO for every query, and what about concurrent queries? So we need to add a way to save this, and make sure that there is some batching going on in there, so we won’t go to the disk all the time. And wait, there is this other feature over there that needs something similar, so we might as well solve both problems at...(Read whole news on source site)

Setting up Azure Data Sync Service with Federations in Windows Azure SQL Database For Reference Data Replication

AddThis Social Bookmark Button
In a previous post, I talked about the ability to use Data Sync Service with Federation Members. In this post, like to walk you through the details. The scenario here is to sync a reference table called language_codes_tbl across federation members. The table represents language codes for the blogs_federation in my BlogsRUs_DB. In my case the topology I created has the root database as a hub and all members defined as regular edge databases. Here is what you need to do to get the same setup 1. Create a “sync server” and a “sync group” called
sync_codes 2. Add the root database as the hub database; blogsrus_db with conflict resolution set to “Hub Wins” and schedule set to every 5 mins. 3. Define the Sync dataset as the dbo.language_code_tbl 4. Add federation member databases into the sync_codes sync group and “deploy” the changes. With this setup, replication happens bi-directionally. This means, I can update any one of the federation member dbs and the changes will first get replicated to the root db copy...(Read whole news on source site)

Build Single Page Apps - Part 5 - HTML 5 and ASP.NET Web Optimization

AddThis Social Bookmark Button
Single Page Apps (SPA) are all the rage, and while it’s exciting to talk about the JavaScript we use in the SPA, the HTML is just as important. If HTML5 tags are used, then its important to make sure that you prepare for a graceful degradation if you want older browser support. Also, the HTML shell should handle this and pull in scripts as efficiently as possible. You can read more about this and other topics in a few weeks when Pluralsight will be releasing my new course titled “Building Single Page Apps (SPA) with HTML5, ASP.NET Web
API, Knockout and jQuery”. Til then, I’ve decided to journalize the creation of the course in a few posts. You can catch up on the previous posts in this series here: Part 1 - The Story Begins (What is the Code Camper SPA?) Part 2 - Client Technologies Part 3 - Server Technologies (the Data Layer) Part 4 – Serving JSON with ASP.NET Web API HTML Best Practices Staring at a blank canvas can be terrifying for developers.

A LEGO story

A couple of days ago LEGO turned 80 years old. Watch this short movie, a great one I assure you, on how it all started out. For me personally, I’ve always loved this little tiny bricks, thinking out ideas, sometimes assembling things with the help of non LEGO bricks just to build something cool. I think I got my first set at the age of 5 or so from my parents. A tiny car with and the driver had a white cowboy hat and also a smiley face. The LEGO I saw before that were mostly very old bricks my grandparents bought for
their children, my uncle and aunt. When I grew up I mostly asked for LEGO for my birthday, Sinterklaas, Christmas eve, sometimes I got it even for making good grades at school. I also witnessed every year more specialized blocks coming out with more dedicated purposes. Personally I still like to believe that the magic of the bricks, the imagination unleashed that came from it and my LEGO Technic sets started off the spark to become an engineer later on. Not only LEGO of course but also some other influences got me there , which is for another story one day, but it for sure did help. Being...(Read whole news on source site)

Microsoft had released Windows 8 Release Preview which can be downloaded from the Official Windows 8 website. Windows 8 includes some interesting features like Live Tiles, Windows 8 UI (Code named “Metro”) and more importantly the UI which looks almost the same like my Windows Phone What is Windows 8 Apps? The Windows 8 Apps is somewhat different from the traditional desktop apps which runs in the full screen mode with a chrome less window and supporting different Layouts and that works well with the touch based devices. One of the important aspect of the Windows 8 UI is the
tiles instead of the icons. Since, Windows 8 (Final version) is set to be released sometime during October/November this year, I thought of getting few apps developed for Windows 8 i.e. Windows 8 Style UI Apps and hence started learning them from last few weeks. As a part of my learning, I will sharing some of my knowledge on tips, How Tis etc. on the Windows 8 Development in the upcoming posts. In the first blog post of this series, I will explain on how one can get started with the Windows 8 App Development. If you want to develop...(Read whole news on source site)
