  • OpenCV compliation on linux: how to feed to it specific zlib lib?

    - by myWallJSON
    I want to compile OpenCV with same zlib as I use for compilation of Boost Iostreams (not system default one). I want to compile OpenCV as static lib, having zlib compiled as static lib. Currently I use something like : ../$CMAKE_PATH -DCMAKE_INSTALL_PREFIX=./$OPENCV_INSTALL_SUBDIR -DBUILD_WITH_STATIC_CRT=ON -DBUILD_SHARED_LIBS=OFF -DBUILD_PYTHON_SUPPORT=OFF -DOPENCV_EXTRA_C_FLAGS=-fPIC -DOPENCV_BUILD_3RDPARTY_LIBS=TRUE make make install echo Done! I wonder: having some $ZLIB_HEADERS and $ZLIB_LIB_FILES_FOLDER path strings how to feed them into cmake to get OpenCV compiled with built by me zlib?

  • Hi Quality texturing.

    - by Tigran
    Hi all. I'm completely new in Open GL, so have a question. I need to apply hi quality texturing on the surface rendered via triangles . But on zooming i continue see the triangle's under the skin, it's not smooth. I use OpenGL built-in minMapping. So I wonder (lookig at other products) do i need to implement my own mipMapping algorithm or I'm doing something wrong ? This is what I want , more ore less, like a quality:

  • Sort months ( with strings ) algorithm

    - by Oscar Reyes
    I have this months array: ["January", "March", "December" , "October" ] And I want to have it sorted like this: ["January", "March", "October", "December" ] I'm currently thinking in a "if/else" horrible cascade but I wonder if there is some other way to do this. The bad part is that I need to do this only with "string" ( that is, without using Date object or anything like that ) What would be a good approach?

  • SAS on OS X any way to run without working within virtual machine?

    - by user309284
    I would like to edit and submit SAS code from emacs (aquamacs) on OS X to SAS running on Vista (through Parallels). Any idea how to do this? I like to do everything through one place and it is really annoying to work within the windows emulator. I have run SAS from a linux server through aquamacs but wonder if something similar can be done locally. Any ideas?

  • iPhone apps for company-internal use - possible?

    - by Michael Stum
    I hope this is still programming related, as SuperUser doesn't seem the appropriate place. Basically I wonder if it is possible to have Applications that are internal to a company on the iPhone? That is something like a companion Application to an Intranet (when Safari and Mail just don't cut it) which wouldn't make sense on the AppStore (and likely wouldn't get approved anyway). Is something like that possible (without Jailbreaking or doing anything else that Apple doesn't normally want)?

  • How do "modern JVMs" differ from older JVMs?

    - by Lord Torgamus
    Here's a phrase that I heard a lot throughout high school and university computer science classes: "That's not an issue for modern JVMs." Usually this would come up in discussions about overall performance or optimization strategies. It was always treated as a kind of magical final answer, though, as if it makes issues no longer worth thinking about. And that just leads me to wonder: what are the differences between the prototypical "modern JVM" and older JVMs, really?

  • If-else-if versus map

    - by perezvon
    Hi, Suppose I have such an if/else-if chain: if( x.GetId() == 1 ) { } else if( x.GetId() == 2 ) { } // ... 50 more else if statements What I wonder is, if I keep a map, will it be any better in terms of performance? (assuming keys are integers)

  • Why do encodeXxx methods in UIComponent accept FacesContext parameter?

    - by Roman
    I haven't ever before created custom components in JSF so I've noticed only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

  • Why do updates inside of a SQL transaction still need disk IO?

    - by usr
    In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?

  • Exception when access inner class reflectively

    - by MikeJiang
    Hi Folk, Here is a sample java program. I wonder why the two approaches reslut different stories. Is it a bug or kind of bitter java feature? And I run the sample upon java 1.5 package test; public class TestOut{ public static void main(String[] args){ new TestIn();//it works Class.forName("test.TestOut$TestIn").newInstance();// throw IllegalAccessException } private static class TestIn{} }

  • Testing code that uses SoftReference<T>

    - by bmargulies
    To get any code with SoftReference<T> to be fully tested, one must come up with some way to test the 'yup, it's been nulled' case. One might more or less mock this by using a 'for-test' code path to force the reference to be null, but that won't manage the queue exactly as the GC does. I wonder if anyone out can share experience in setting up a repeatable, controlled, environment, in which the GC is, in fact, provoked into collecting and nulling?

  • Which is clearer form: if(!value) or if(flag == value) ?

    - by CodexArcanum
    I understand this is a subjective question, so I apologize if it needs to be closed, but I feel like it comes up often enough for me to wonder if there is a general preference for one form over the other. Obviously, the best answer is "refactor the code so you don't need to test for falsehood" but sometimes there's no easy way to do so and the "else" branch is simply to continue processing. So when you must have an "if not false" construct, which is the preferred standard: The not operator if(!value) Or the test for false if(value == false)

  • Array of NSButton

    - by mralvin
    I wonder if I can do something like IBOutlet NSButton * aButton[100]; It turns out that aButton cannot be seen in the interface builder. My app has lots of buttons and I want to see if there are way I can use looping to iterate the state of all buttons.

  • Load a list of localized strings at once in IOS

    - by Victor Ronin
    I want to show a table with the list of strings which are localized. The straightforward method would be: a) Point data source to my ViewController b) Define an array c) Allocate the array in my ViewController and init (arrayWithObjects) it with the strings from localized resources (NSLocalizedString) d) Use this array in UITableViewDataSource delegated methods Mainly my concern is item b). The construction looks quite heavy and I wonder whether I can somehow specify and load whole list of localized string at once.
