  • Trying to convert a 2D image into 3D objects in Java

    - by Kyle
    Hey, I'm trying to take a simple image, something like a black background with colored blocks representing walls. I'm trying to figure out how to go about starting on something like this. Do I need to parse the image and look at each pixel or is there an easier way to do it? I'm using Java3D but it doesn't seem to have any sort of built in support for that...

  • Get individual query parameters from Uri

    - by Ghostrider
    I have a uri string like: http://example.com/file?a=1&b=2&c=string%20param Is there an existing function that would convert query parameter string into a dictionary same way as ASP.NET Context.Request does it. I'm writing a console app and not a web-service so there is no Context.Request to parse the URL for me. I know that it's pretty easy to crack the query string myself but I'd rather use a FCL function is if exists.

  • writing large excel spreadsheets

    - by pstanton
    has anybody found a library that works well with large spreadsheets? I've tried apache's POI but it fails miserably working with large files - both reading and writing. It uses massive amounts of memory leaving you needing a supercomputer to parse or create a 20+mb spreadsheet. Surely there is a more memory efficient way and someone has written it?!

  • Why do so many wpf controls implement CLR properties instead of dependency properties ?

    - by msfanboy
    Hello, is it because the controls programmers are lazy, too hard to implement or not knowledgeable? Wether they are custom controls from 3rd party vendors or Microsoft itself, very much controls have often clr properties instead of DP. Result is I can not bind to them and is wpf not all about binding? :/ My next side question would be, why do so many wpf controls offer visual parts but they are not member of the visual tree ? see wpf datagrid columns, headers... What do you think?

  • How do compare dates when one of those are in string format in android

    - by Raj
    I am very much new to android so need some good help with a code example. I am getting a date in form of string from a server in the following format 2012-08-17 00:00:00 I want to compare this string with current date to find the difference between the dates in the form of year, months and days...

  • latex computer output segments

    - by Flavius
    I have a verbatim environment containing computer output as text. This text is sematically made of two sections, each section being separated from the other by an empty line. The number of sections and their content is known, so I don't need to parse the text, but the line between the sections is very important (as it gives semantics to the "text"). Each segment is made of multiple lines. How could I write (1) and (2) on the left handside at the centre of each segment?

  • Languages for implementing decision trees

    - by Shailesh Tainwala
    What would be a good choice of programming language in which to implement a decision tree? The results of the implementation will be for personal use only, so no need to consider ability to publish etc. I have heard that Octave is a good option, can anyone explain why a matrix based language is recommended for implementing decision trees?

  • PHP's DOMXPath is stripping out my tags inside the matched text.

    - by Mint
    I asked this question yesterday, and at the time it was just what I needed, but while working with some live data I discovered that is wasn't quite doing what I expected. http://stackoverflow.com/questions/2571232/parse-html-with-phps-html-domdocument I gets the data from the HTML page, but then it also strips out all the HTML tags inside the captured block of text, which isn't what I want. (I might wan't to take some of the tags out, but not all, and this can be done later)

    It's a bit ugly that many lines of code fall into "__main__". Can someone give me a tip of how to move SessionMiddleware into handle method? I should notice that I use session in CoreXmlParser. Thanks in advance ! def handle(environ, start_response): req = webob.Request(environ) c = CoreXmlParser(req) resp = webob.Response(body=c(), charset = 'utf-8', status='200 OK', \ request=req, content_type='text/xml') resp(environ, start_response) return resp.app_iter if __name__ == '__main__': #parse config file for session options app = SessionMiddleware(handle, some_session_opts_here) from flup.server.fcgi import WSGIServer WSGIServer(app).run()
