  • Reason behind system power usage?

    - by kumar
    Hi, when the number of applications running in a pc increases, the power consumed by the PC is also increasing. Is this correct? I think the reason behind this is CPU. Please let me know what role the CPU plays for more power usage. Thanks, Kavi

  • Why manual memory management?

    - by user333639
    Are there any plans for auto memory management? What are the advantanges of manually managing memory...does it conserve memory in the long run? I have noticed in .Net Windows Applications - they are very sluggish - is this partly due to the garbage collector not working correctly?

  • Android Development Device

    - by jamesaharvey
    I'm looking to get a device (phone, tablet, etc.) for developing Android applications. I know I can use the emulator to get me started, but I feel like that will only get me so far along. I'm looking for something reasonably priced, and I don't want a phone contract, data plan, etc. Anyone have any suggestions?

  • iPhone apps for company-internal use - possible?

    - by Michael Stum
    I hope this is still programming related, as SuperUser doesn't seem the appropriate place. Basically I wonder if it is possible to have Applications that are internal to a company on the iPhone? That is something like a companion Application to an Intranet (when Safari and Mail just don't cut it) which wouldn't make sense on the AppStore (and likely wouldn't get approved anyway). Is something like that possible (without Jailbreaking or doing anything else that Apple doesn't normally want)?

    Thank you in advance. I need to get data from the serial port of a linux system and convert it to TCP/IP to send to a server. Is this difficult to do?

  • Is it possible to use the WP7 Panorama or Pivot in SL4?

    - by Detroitpro
    I'm making pretty heavy use of the Panorama and Pivot controls in my WP7 applications. Is it possible to use these same controls in a standard Silverlight (4) application? http://phone.codeplex.com/ I added the dll's, was able to compile and create the controls in my views. However; I was not able to "Scroll". I thought they used the "LeftMouseDown" event handlers but I guess I'm wrong.

  • Why is hibernate open session in view considered a bad practice?

    - by HeDinges
    And what kind of alternative strategies do you use for avoiding LazyLoadExceptions? I do understand that open session in view has issues with: Layered applications running in different jvm's Transactions are committed only at the end, and most probably you would like the results before. But, if you know that your application is running on a single vm, why not ease your pain by using an open session in view strategy?

    - by davemackey
    I'd like to build a dashboard interface for an application I am working on. I want users to logon and get a birds eye view of the status of applications, outstanding issues, etc. I'm wondering if there are some good, pre-made controls rather than writing these from the ground up?

  • How to communicate with a USB device under Windows and Java?

    - by Gili
    I'd like to communicate with a USB device under Windows and Java but I can't find a good library to do so. I don't want the user to have to install any extra hardware or device drivers to make this work. That is, I want to be able to interact with USB just like other Windows applications do. I am familiar with jUSB and JSR 80 but both seem to be dead projects (at least for Windows).

  • jquery in ajax loaded content

    - by Kim Gysen
    My application is supposed to be a single page application and I have the following code that works fine: home.php: <div id="container"> </div> accordion.php: //Click functions: load content $('#parents').click(function(){ //Load parent in container $('#container').load('http://www.blabla.com/entities/parents/parents.php'); }); parents.php: <div class="entity_wrapper"> Some divs and selectors </div> <script type="text/javascript"> $(document).ready(function(){ //Some jQuery / javascript }); </script> So the content loads fine, while the scripts dynamically loaded execute fine as well. I apply this system repetitively and it continues to work smoothly. I've seen that there are a lot of frameworks available on SPA's (such as backbone.js) but I don't understand why I need them if this works fine. From the backbone.js website: When working on a web application that involves a lot of JavaScript, one of the first things you learn is to stop tying your data to the DOM. It's all too easy to create JavaScript applications that end up as tangled piles of jQuery selectors and callbacks, all trying frantically to keep data in sync between the HTML UI, your JavaScript logic, and the database on your server. For rich client-side applications, a more structured approach is often helpful. Well, I totally don't have the feeling that I'm going through the stuff they mention. Adding the javascript per page works really well for me. They are html containers with clear scope and the javascript is just related to that part. More over, the front end doesn't do that much, most of the logic is managed based on Ajax calls to external PHP scripts. Sometimes the js can be a bit more extended for some functionalities, but all just loads as smooth in less than a second. If you think that this is bad coding, please tell me why I cannot do this and more importantly, what is the alternative I should apply. At the moment, I really don't see a reason on why I would change this approach as it just works too well. I'm kinda stuck on this question because it just worries me sick as it seems to easy to be true. Why would people go through hard times if it would be as easy as this...

  • Architecture Suggestions/Recommendations for a Web Application with Sub-Apps

    - by user579218
    Hello. I’m starting to plan an architecture for a big web application, and I wanted to get suggestions and/or recommendations on where to begin and which technologies and/or frameworks to use. The application will be an Intranet-based web site using Windows authentication, running on IIS and using SQL Server and ASP.NET. It’ll need to be structured as a main/shell application with sub-applications that are “pluggable” based on some configuration settings. The main or shell application is to provide the overall user interface structure – header/footer, dynamically built tabs for each available sub-app, and a content area in which the sub-application will be loaded when the user clicks on the sub-application’s tab. So, on start-up of the main/shell application, configuration information will be queried from a database, and, based on the user and which of the sub-apps are available, the main or shell app would dynamically build tabs (or buttons or something) as a way to access each individual application. On start-up, the content area will be populated with the “home” sub-app. But, clicking on an sub-app tab will cause the content area to be populated with the sub-app corresponding to the tab. For example, we’re going to have a reports application, a display application, and probably a couple other distinct applications. On startup of the main/shell application, after determining who the user is, the main app will query the database to determine which sub-apps the user can use and build out the UI. Then the user can navigate between available sub-apps and do their work in each. Finally, the entire app and all sub-apps need to be a layered design with presentation, service, business, and data access layers, as well as cross-cutting objects for things such as logging, exception handling, etc. Anyway, my questions revolve around where to begin to plan something like this application. What technologies/frameworks would work best in developing a solution for this application? MVC? MVP? WCSF? EF? NHibernate? Enterprise Library? Repository Pattern? Others???? I know all these technologies/frameworks are not used for the same purpose, but knowing which ones to focus on is a little overwhelming. Which ones would be the best choice(s) for a solution? Which ones work well together for an end-to-end design? How would one structure the VS project for something like this? Thanks!
