  • Camera and Image recognition

    - by kjh
    I recently watched a youtube video where a guy got a camera to recognize when a rubik's cube was held up to it, and it captured the 9 square color combination before snapping a picture of the cube and displaying the 3x3 grid on the screen of his computer. What kind of programming is this and where would I start reading to get into this sort of thing? specifically, controlling a camera, and getting it to pick out certain parts of an image and translate that data.

  • Keeping DB Table sorted using multi-field formula (Microsoft SQL Server)

    - by user298167
    I have a JOB table, with two interesting columns: Creation Date Importance (high - 3, medium 2, low - 1). A JOB record's priority calculated like this: Priority = Importance * (time passed since creation) The problem is, every time I would like to pick 200 jobs with highest priority, and I don't want to resort the table. Is there a way to keep rows sorted? I was also thinking about having three tables one for High, Medium and Low and then sort those by Creation Date.

  • JVM performance test suite

    - by pierr
    Hi, I have just ported phoneME to our MIPS platform. I feel it runs not that fast; however, is there any performance test suite I can run against to get some quantitative measurement of the performance? I might need to pick some weak points for optimization. In addition, what are common criterions used to evalute a JVM ?

  • How can I unattach an element from another element in the XAML tree?

    - by Edward Tanguay
    In my Silverlight application, I load all the images I need at application start and store them in a dictionary. Then as I need them I pick them out of the dictionary and attach them in XAML trees etc. However, I have the problem that if I attach an Image object to a Grid, then want to use that image again, it tells me: The image element is already a child of another element. How can I run through my dictionary and "detach all images from parent XAML elements"?

  • Which use cases make temporary JMS queues a better choice than persistent queues?

    - by Stephen Harmon
    When you are designing a JMS application, which use cases make you pick temporary queues over persistent queues? We use temporary queues for response messages. We're having some issues maintaining connections to the temp queues, though, so I am testing persistent response queues, instead. One clear disadvantage of persistent queues is that your application has to "know" about them beforehand. If that's not a big deal, though, are there use cases where temp queues are the obvious choice?

  • Is MobiForms for Android worth investigating ?

    - by Alan B
    I'm working my way through the NotePad tutorial, and that's all fine - I'm not a Java programmer but it's close enough to C# (or vice versa) to make it easy to pick up. I'm surprised that there aren't any RAD tools for Android apart from Mobiforms. Is there anyone out there with experience of Mobiforms ?

  • ServerVariables and POST Data

    - by tyndall
    I've got a piece of tracking code which is capturing REMOTE_HOST, SERVER, REQUEST_METHOD, SCRIPT_NAME and QUERY_STRING. It grabs these from ServerVariables and sticks them in a database by user and IP. What is the best way to pick up the exact contents of what was posted back to a URL in ASP.NET? Is there an HTTP_POST? I'd rather not grab something and then have to parse it.

  • Linq to Sql: Generic Stored Procedures

    - by Eric
    Hello everyone, I am using Linq-to-Sql for a C# application and am currently working on some stored procedures. The application is for a newspaper, and a sample stored procedure is the following: ALTER PROCEDURE dbo.Articles_GetArticlesByPublication @publicationDate date AS SELECT * FROM Articles WHERE Articles.PublicationDate=@publicationDate Anyway, this query gets all of the articles where the publication date is equal to the argument (publicationDate). How can I alter this so that the argument can handle multiple publication dates? Also, I'd prefer not to use "BETWEEN," rather, I want to pick and choose dates.

    - by Zack
    What are the advantages and disadvantages of Hibernate & EJB3 relative to each other? I found this post, but it didn't really address my question.
