    - by Totty
    I have: var f1 = function(a){ alert(a) } var f2 = function(data, method){ method(data) // the problem is here, // the method f1 is not called. Is there a way to call that method f1? // the method f1 might not be in this scope, the method f1 can // be in a class or like this... } f2(a, f1) The question is: Is there a way to call that f1 from f2, from the passed method? thanks

  • Do we really need high level languages? [closed]

    - by i_love_c
    Seeing the amount of softwares developed (and still being developed) in C and considering the fact that C currently tops the TIOBE chart, I have this one question for you all: Do we really need high level languages like C# or F# or Ruby? Don't you think these so-called high level languages are actually spoiling programmers and resulting in suboptimal and non-efficient softwares?

  • unique substrings using suffix tree

    - by user1708762
    For a given string S of length n- Optimal algorithm for finding all unique substrings of S can't be less than O(n^2). So, the best algorithm will give us the complexity of O(n^2). As per what I have read, this can be implemented by creating suffix tree for S. The suffix tree for S can be created in O(n) time. Now, my question is- How can we use the suffix tree for S to get all the unique substrings of S in O(n^2)?

  • Present a default window layout on startup in Windows 7

    - by sipickles
    Hello, I have a Win7 PC in use as part of an experiment control system. The experiment in question uses 4 windows simultaneously, and I would like to find away to open, position and size these 4 windows with a script. The script would run at start up, so that the newly booted PC presents the user with the four windows as default. Obviously I can use a batch file in the startup folder to open windows and run applications, but is there a way to specify the layout of these windows? Many thanks Si

  • Local-only version of `hg outgoing`?

    - by Grumdrig
    The command hg outgoing compares the local repo to the default push location; it accesses the push location to do it. I'd like to ask the question "have I checked in changes in my local repo since my last hg push?" without having to access the remote repo. It seems like there might be enough info in the local repo to figure that out; if so, is there a command to determine that?

  • Implementing a 30 day time trial

    - by svintus
    Question for indie Mac developers out there: How do I implement a 30-day time trial in a non-evil fashion? Putting a counter in the prefs is not an option, since wiping prefs once a month is not a problem for an average user. Putting the counter in a hidden file somewhere sounds a bit dodgy - as a user I hate when apps sprinkle my hard drive with random files. Any ideas?

  • How do i query to list out all commits by a user to a subversion repository?

    - by VDev
    The title pretty much sums up my question, I would like to find all commits I have ever done to the subversion repository. Not just commits in current snapshot. More importantly, I would like to organize the file lists by the SVN comment used while committing. Thank you Edit: I am thinking maybe a python or shell script that would parse the output of svn log | grep username to extract revisions and then pipes the output to svn log -r [revision numbers go here] Maybe some scripting gurus can help me out..

    - by aaa
    If I have have some overloaded ostream operators, defined for library local objects, is its okay for them to go to std namespace? If I do not declare them in std namespace, then I must use using ns:: operator <<. As a possible follow-up question, are there any operators which should go to standard or global namespace?

  • What happens if I give more inputs in estimateRigidTransform or getAffineTransform?

    - by user3531608
    I am using estimateRigidTransform with about two vectors of 100 points and is working FINE. But somehow getAffineTransform doesn't work. I know that findHomography finds the best matrix using RANSAC and getPerspectiveTransform needs only 4 points. My question is what happens if I give more inputs in estimateRigidTransform or getAffineTransform? Does it take only 4 points from input matrix? Or do some kind of RANSAC?
