    - by user308827
    Hi, I have a raster file (basically 2D array) with close to a million points. I am trying to extract a circle from the raster (and all the points that lie within the circle. Using ArcGIS is exceedingly slow for this. Can anyone suggest any image processing library that is both easy to learn and powerful and quick enough for something like this? Thanks!

  • jQuery detect visible but hidden elements

    - by IP
    This seems like it should be fairly easy - but I can't find the right selector for it According to the docs (http://api.jquery.com/hidden-selector/ and http://api.jquery.com/visible-selector/)... Elements can be considered hidden for several reasons: An ancestor element is hidden, so the element is not shown on the page. What I want to detect is "this element is visible, but is contained in a hidden parent". Ie, if I made the parent visible, this element would also be visible.

  • C check before writing to closed pipe

    - by Gary
    Is there an easy way to check if a pipe is closed before writing to it in C? I have a child and parent process, and the parent has a pipe to write to the child. However, if the child closes the pipe and the parent tries to read - I get a broken pipe error. So how can I check to make sure I can write to the pipe, so I can handle it as an error if I can't? Thanks!

  • Python operators returning ints

    - by None
    Is there any way to have Python operators line "==" and "" return ints instead of bools. I know that I could use the int function (int(1 == 1)) or add 0 ((1 == 1) + 0) but I was wondering if there was an easy way to do it. Like when you want division to return floats you could type from __future__ import division. Is there any way to do this with operators returning ints? Or could I make a class extending __future__._Feature that would do what I want?

  • powershell.exe tab completion - list alternatives?

    - by J Cooper
    I've never really used PowerShell before, and playing with it a bit, it looks like it uses cmd.exe's style of tab completion (fill in the first likely candidate, and then you can use tab to cycle through other alternatives). I'd much prefer the way e.g. bash works, where if there are multiple candidates, it shows a list of them. Is there an easy way to turn this on, by any chance?

  • Windows Phone 7: Existing Libraries Not Supported?

    - by Peterdk
    I was hoping it was as easy as referencing my existing libraries to use them with WP7. However, it complains about not able to load them because of .Net CF when I actually use them. Do i need to recompile them to .NET CF or something? I thought the big plus of WP7 was: leveraging your existing codebase...? How can I leverage my existing codebase if I need to strip everything out of it and maintain multiple versions?

  • MySQL app with Cassandra in mind

    - by SODA
    I am planning to make a web app which will eventually use Cassandra. But now that I don't have it and don't have server(s) to run it from, I'd like to start by using MySQL. The question is, is it possible to structure data and queries in such a way that it would be fairly easy to later port it to Cassandra? Main idea, I guess, would be writing MySQL queries that would be possible to change to same Cassandra queries. Maybe you have a better suggestion?

  • Programmatically access currency exchange rates

    - by Adam Pierce
    I'm setting up an online ordering system but I'm in Australia and for international customers I'd like to show prices in US dollars or Euros so they don't have to make the mental effort to convert from Australian dollars. Does anyone know if I can pull up to date exchange rates off the net somewhere in an easy-to-parse format I can access from my PHP script ? UPDATE: I have now written a PHP class which implements this. You can get the code from my website.

  • Open source tool for hosting projects similar to "Google Project Hosting"

    - by Jeesmon
    We are looking for open source tool for hosting our internal projects like "Google Project Hosting". The tool should support individual wiki and version control for each project and it should be easy to configure for each project like in google code. We explored trac but seems it lack good support for multiple projects. The tool will be installed in our internal host and cannot use hosted service. A java based tool will be ideal.

  • Calculating the maximum distance between elements of vector in Matlab

    - by lhahne
    Lets assume that we have a vector like x = -1:0.05:1; ids = randperm(length(x)); x = x(ids(1:20)); I would like to calculate the maximum distance between the elements of x in some idiomatic way. It would be easy to just iterate over all possible combinations of x's elements but I feel like there could be a way to do it with Matlab's built-in functions in some crazy but idiomatic way. Any ideas?
