  • problem with background subtraction

    - by riyana
    I'm doing background subtraction using opencv. The problem is the foreground object is not always detected correctly. To deal with this I would like to use four or five images, and take their average as the background image. How can I do that?

  • How do I constrain the SCons Command builder to run only if its dependencies have changed?

    - by saffsd
    I am using the Command builder in scons to specify that a particular script needs to be invoked to produce a particular file. I would like to only run the script if it has been modified since the file was previously generated. The default behaviour of the Command builder seems to be to always run the script. How can I change this? This is my current SConstruct: speed = Command('speed_analysis.tex','','python code/speed.py') report = PDF(target = 'report.pdf', source = 'report.tex') Depends(report, speed)

  • Iterating Collection In Two Threads

    - by ChloeRadshaw
    This question relates both to C# and Java If you have a collection which is not modified and that collection reference is shared between two threads what happens when you iterate on each thread?? ThreadA: Collection.iterator ThreadA: Collection.moveNext ThreadB: Collection.iterator ThreadB: Collection.moveNext Will threadB see the first element? Is the iterator always reset when it is requested? What happens if this is interleaved so movenext and item is interleaved? Is there a danger that you dont process all elements??

  • Post/Redirect/Get Pattern and Sticky Forms

    - by Scott Christopherson
    I'm using the Post/Redirect/Get pattern on a form of mine. I've never used this approach before and I'm trying to figure something out: Normally, I always just displayed the posted form again when there were validation errors and displayed POST values in the form (sticky form). However with the PRG pattern, the form is displayed after a redirect, so there aren't any POST values. So my question is, how can I implement the PRG pattern and still have sticky forms?

  • What's your release process for your commercial application?

    - by dr. evil
    If you are developing a commercial desktop application, what's your release process? Sample process: Develop it: Patch bugs, add features, etc. Feature Freeze (do not fix, add anything unless it's absolutely required) Test it If everything is OK release it, if it's not fix it, test it, release it I think the most crucial question is what's your approach to "feature freeze test release" cycle? Or do you test it more frequently that you don't need such a cycle and your software is always ready for public release?

  • best tool for monitoring incoming/outgoing requests (PC/MAC)?

    - by dave L
    What are the best tools for monitoring incoming/outgoing requests from a PC or MAC? Any tool that works well on both? (my guess is N/A) I'm interested in capturing HTTP (possibly even TCPIP)-based requests and responses. Does Wireshark always come out on top or are there alternatives people feel are better? Thanks for any info.

    I have thos piece of code: Math&&Math.random?Math.floor(Math.random()*10000000000000):Date.getTime(); And as far as i know && is logic operator for AND, so im trying to convert this into PHP and this is where i got: intval(floor(time()/10800000)%10+(rand()?floor(rand()*10000000000000):time())) The problem is that i can't understand the first part Math&& Can anyone help with this one cause i always get negative result, when i should get positive (probably the logic rand-time is not working in my php example)

  • Watir not working in Windows 7

    - by Ben Mills
    I recently did a fresh install of Windows 7. I installed Ruby 1.8.6 and Watir via RubyGems. When I try to run a Watir script, IE opens and the first page is called, but the problem seems to be that the script doesn't wait for the page to finish loading (which it's always done in the past). Subsequent lines in the script try to access page elements that haven't loaded yet. Is anyone else having this problem?

  • Can Java's random function be zero?

    - by ThirdD3gree
    Just out of curiosity, can Math.random() ever be zero? For example, if I were to have: while (true){ if (Math.random() == 0) return 1; } Would I ever actually get a return of one? There's also rounding error to consider because Math.random() returns a double. I ask because my CS professor stated that random() goes from 0 to 1 inclusive, and I always thought it was exclusive.
