We tried to migrate Here SDK from Premium Edition to Navigate Edition.
And there is a method to check the validity of a coordinate in Coordinate class in Premium Edition.
But we can not find such as the method in Navigate Edition.
I have tried to seach the methods in GeoCoordinates class in Navigate Edition.
But I can not find it.
I wish I could confirm the validity of a coordinate before I used the coordinate.
How can we do that in Navigate Edition?
You can do this check on your own: If the latitude is in the range [-90, 90] and longitude in the range [-180, 180] it can be considered to be valid.
At least, a formal validity check is not offered (yet) for the new 4.x HERE SDK platform.

I use ITK 4.3, VTK and Qt on Visual Studio 9. How do I add ITK-SNAP?
I want to know the difference between ITK and ITK-SNAP and what does ITK-SNAP add compared to ITK.
I started working with ITK. Do I need to change my code or can I continue in my project?
SNAP is a software application used to segment structures in 3D medical images. It provides semi-automatic segmentation using active contour methods, as well as manual delineation and image navigation. The software was designed with the audience of clinical and basic science researchers in mind, and emphasis has been placed on having a user-friendly interface and maintaining a limited feature set to prevent feature creep. ITK-SNAP is free software, provided under the General Public License. ITK-SNAP binaries are provided free of charge for academic or commercial use.
This tutorial provides a step by step walkthrough of building ITK-SNAP 2.4.0 from source on Windows. We will be using Microsoft Visual Studio 2010 for building the application. Make sure you have VS 2010 installed and VS Service Pack 1 as well. (if required) : Click Here for full tutorial
ITK is abbrevation of Insight Segmentation and Registration Toolkit which is open source library which provide image processing algorithms to develop your application on different platforms ex python, c++.You can follow this link: http://qtitkvtkhelp.blogspot.in/2012/11/itk-installation-for-msvc.html to build ITK and use that in your application. ITK-SNAP It is an open source software you can directly install it from here. I think this is solution for all of your questions.
I've seen this question but the answers are simply not good enough. I've searched the web and could find a clear listing of the main differences.
I am particularly surprised to see contradictions in the above link, that holds only 4 short answers.
So the question is, beyond support, what are (all) the differences between Alfresco Community and Enterprise editions (for the current versions of course)?
Are there functional or technical features that available in the Enterprise edition, that are not in the community edition?
I find it strange that it's so difficult to get a clear list. Looking at the forums to find this answer is not a serious option from a business perspective.
Until now, I found this link to be useful, but it's from 2009.
In particular, I find the platform support interesting, with the community edition supporting only lamp stuff:
Linux
MySQL
Tomcat
OpenLDAP
Firefox
And the enterprise edition supporting:
Windows
SQL Server
WebLogic, WebSphere
AD/Kerberos
IE and Safari
Apparently, these features are only available in the enterprise edition:
JMX monitoring
Runtime admininstration: What's that exactly? And what's in the community edition then?
Runtime indexing consistency check and update: What's in the community edition then?
High performance and availability: How is that implemented and what's in the community edition then?
Storage policies
Open source and proprietary technology stack support: which ones exaclty? Which ones are supported in the community edition?
If anyone could guide me towards serious documentation about these differences, that would be great.
I also went through the wiki but could not find an answer to my questions in there.
differences between Enterprise and Community vary in detail from version to version and are mainly visible for administrators. We see or maintain both flavors of Alfresco in midsize to very large environments and I would say it's more or less a question of taste and budget what the best decision / edition is for you. Excellent skills in infrastructure and java are highly advisable for both editions to run Alfresco in production.
The technical differences are not as dramatic as not being able to provide very similar functionality for the users - so if you're actually in a decision you should focus on a good technical partner, the support services and maybe the fact that you only get official patches in the Enterprise subscription, not on the Community. BTW Alfresco Enterprise is not Open Source but this is not a real point of interest for most end users. You can access the code as a subscription customer but it is not public available/accessible.
The main differences in features are already named more or less:
Administration
Enterprise has more views and setting in the admin web GUI. In Community you can access most configuration only from the command line. This may be a restriction but in real live Administrators prefer the command line and scripting automation.
Enterprise lets you change some Alfresco settings during runtime (most settings still require restart). Some can be change in the GUI and more in the jmx interface. Also you're able to stop and start subsystems like the CIFS protocol server. We use this feature to switch a system in read only mode. This point is meant with "runtime admininstration". Community requires restart of the service for most configuration changes. It is possible to work around this by advanced scripting like groovy or by implementing modules.
Indexing
Runtime indexing consistency check and update is not a self healing functionality as expected. You will have to learn (at least for now) that you have to recreate the Alfresco index from time to time even in Enterprise environments and that it is better to focus on good strategies how to speed recreation or how to setup standby indexes instead of hunting failed indexing transactions using the check and update methods. For major document model changes you need to recreate the index anyway.
High performance and availability
This is mainly the cluster and replication functionality which is no longer available in Community. It's similar to MS Clusters: It's a lot, lot work for very view more availability since some concepts are missing. The price is high in terms of complexity and can end up in loss of robustness. Even with enterprise support it's a hard job to keep a alfresco cluster running - so you need very good arguments why to go this way. But of course: its possible and available!
High performance: There shouldn't be any difference and if - I'm very curious about the explanation.
Technology stack
The main difference is the database support. In the Community you only can choose between MySQL and Postgres (No Oracle or MS SQL for Community). All other technologies are independent from Enterprise or Community (AD, Kerberos, OS, Browser, ...)
Java Container: I believe over 95% of all Alfresco installations run in tomcat. That's the configuration which is documented, tested and scales. Using WebLogic or WebSphere gives you no added value except new challenges - quite the contrary: You have to solve most issues for yourself and can't benefit from others experience.
Storage policies: I'm not pretty sure and should check in 4.2.x if the Content Store Selector / Storage policies is no longer available in the Community, but it was there in the 3.x versions.
[Edit]: storage policies have been removed in Community 4.2.x:
NoSuchBeanDefinitionException: No bean named 'storeSelectorContentStoreBase' is defined
If there is a really need for this functionality someone may re-enable that feature by coding a module for Community.

This page explains the difference between the editions:
https://wiki.alfresco.com/wiki/Enterprise_Edition
This page is the canonical, comprehensive list of the differences.
If you are considering an Enterprise Subscription and you have a question that isn't answered by what you can find on that page, you should talk to your account rep.
Well, regarding JMX monitoring:
Runtime administration: Alfresco enterprise allows to perform certain actions on Alfresco subsystems without restarting the server. This allows you to be very fast during debugging/developing and also making changes in production environment. Also you can access the JMX interface that supports JMX Remoting.
There is no consistency check or update, until you restart the server (during the startup you have to validate/check/rebuild your indexes). There is an option in alfresco.global.properties (or the original repository.properties config file) for that. If you have some inconsistencies in the Alfresco Community index, you're gonna have a bad time xD.
Alfresco Enterprise has specific license for clustering your architecture, the Community edition doesn't support those systems. Replicate and cluster Alfresco is one of the main improvements in performance/scalability/availability you could achieve.
The storage policies allow you to use Content Store selectors in Alfresco Enterprise. You can manage a primary and a secondary file store, and map/connect these stores in your architecture. The Community Edition allows you only to use one content store at a time.
These include everything inside Alfresco (Spring Framework, Apache-Lucene/Solr, Tomcat, and so on), because with the Enterprise license you have also the full support with everything inside the Alfresco package. The difference is that the Community is based on daily builds, supported by community, and therefor not guaranteed. The Enterprise support helps you resolve many problems that you might encounter during developing and in production environment, not only Alfresco related, but also on some configurations on supported platforms (Windows/Linux), your web application servers, and so on.
Hope it helps.
D3D11 in Metro doesn't support D3DReflect.
Why not?
My API uses this to dynamically get the constant buffer sizes of shaders.
Is there any other way to get a constant buffer size dynamically in D3D11 without a ID3D11ShaderReflection object? Or get the constant variables by name?
What if I wanted to make a shader compiler tool for Metro?
What is I wanted to make an Art application that allowed you to dynamically generate complex brushes that requires shader generation. But this doesn't work.
Does Windows(Desktop), OSX, Linux, iOS or Android have these shader limitations?
No, so why on earth does Metro?
See http://social.msdn.microsoft.com/Forums/en-US/wingameswithdirectx/thread/9ae33f2c-791a-4a5f-b562-8700a4ab1926 for some discussion about it.
There is not an official position explaining why they made such restriction, but it is very similar to the whole restriction of dynamic code execution on WinRT. So your application scenario is unfortunately not possible.
Though, It would be feasible to hack/patch d3dcompiler_xx.dll and redirect all dll imports to call another DLL that would use authorized only APIs, but that's quite some work, and It is not even sure that this is legal (even by extracting the dll code from original d3dcompiler and rebuilding a new dll).
Another option for your scenario is to send the shader over the internet to a server that compiles and returns bytecode and reflection info... far from being perfect.
Among the platforms you mention, probably iOS is the one that could have the same restriction (I don't develop on this platform, so I can't confirm it).
this is just kind of a broad question to get some starting points.
I am looking to purchase a Microsoft Kinect for the purposes of doing some programming with it.
I prefer programming in C++, and have typically made interfaces using QtCreator as opposed to VS. I see that there are a couple of Kinect's to buy - the normal gaming device, and "Kinect for Windows" which includes the SDK, it seems? Do i really need that, or can I buy the cheaper Kinect gaming device? I see that there is an openkinect project out there - I assume that is the FOSS equivalent of the "for Windows" version? I think I read somewhere the MS SDK is only going to work in Visual Studio (which I have), but if its that much better, I guess I could switch to VS for these projects.
Secondly, I am interested in doing some motion capture / 3d model projection onto the 3d objects I capture. Do I definitely need a depth camera to do this type of thing? (As in - map a "monster" to a human who's moving around in the scene). This is where I thought OpenCV might come in handy - and I am especially interested in OpenCV because of its GPU-enabled features.
Thanks for the discussion (in advance)
I am working on the kinect device for reaserch projects so I think I can anwser to some of your questions...
Some Open SDK to use with kinect :
If you like QT, you will like the : QT Kinect Widget. I never test this widget.
OpenNI : OpenNI. That is the official driver of the sensors like Kinect or Asus XTion pro (also called the RGBD sensors). This API can provide you either the raw point cloud or the skeleton if you want to make a smart HMI quickly.
The Point Cloud Library : PCL. You can use this library to acquire the point cloud, and then use all algorithm presents in this library to develop you own point cloud application !
And of course, the OpenCV Wrapper : OpenCV. This will provide you a depth map (not a point cloud).
All this SDK are usable with QtCreator both on linux and windows.
The Hardware :
If you buy a kinect in a video game store, you will not be able to plug it on your computer because the socket isn't standard. You will need to buy an adapter : KinectAdapter. This adapter is required because Kinect have a DC motors, and USB can't provide enough power for this motor.
If you buy an Asus XTION Pro live, you will not need any adapter. There is no DC motors on this device and i am quite sure that is exactly the same device than kinect. I think that Microsoft didn't "invent" the kinect, but OpenNI does ! Asus bought a licence to OpenNI for their XTION, and Microsoft bought openni for their kinect :)
Your application
I never done Motion capture and 3D model projection, but I can tell you that it will be easier to do it with a depth sensor. I think the best way to do it is to use PCL to acquire point cloud and RGB image. Thanks to the plane detectors in PCL you can compute the projection of your 3D model, and use OpenCV to display the RGB data and the projected model.
I want to develop application for the Calling innovator contest 2011. It seems the application developed using 4.6.3 (NokiaQtSDK) are accepted.
I have some questions that needs some help
Can we develop application that uses VOIP and APS Plugins ?
Is it acceptable for the contest , since these plug ins are more platform specific ?
Can we ignore the built in Nokiaqtsdk and use the 4.6.3 sources with S60 to develop this app ?
Does Calling Innovator Contest 2011 have a separate forum for discussion?
I don't get it what stops you from reading competition's rules. Once you do that, adopt the simple rule: whatever is not expressly prohibited is to be considered allowed. Yes, you can use all the platform specific APIs you want and you can develop it with any SDK as long as you know what you are doing and you get a working application to submit to the Ovi Store. Just make sure that the most of it is made with Qt, since that is indeed a requirement.
