  • May I know what python is great at [on hold]

    - by user108437
    I am amazed by python on how tidy the code is, so i decided to learn it, and 2 days pass and I am completely in love with python, but I just code it for hobby thing like chatting robot, uploading to file hosting scripts, etc that small tools for my own daily internet life, and not much for work. I can't find a real life usage of python here. I live in Singapore, when I see in the job skill needed, from those companies hiring, only one asking for python. so I begin to be doubtful whether this skill of mine really worth my time investing it? I also heard about django, and don't know how much popular it is comparing to asp.net. So i ask your help to tell me your country and how popular python there and whether you like python or not? I really like python because of the easy scripting language (not complicated like C++) but the usefulness is almost near C++ where many open source library out there that can run both in windows and linux, so the portability is great! i just want to justify my time for learning python, as because my job does not require python, and I don't have much time at home to learn something new.

  • Using background-attachment:fixed in safari on the ipad

    - by chris_bcn
    I'm looking to recreate an effect similiar to the popular science app. Basically have one big background image and then have HTML/CSS layer on top of that. When the user scrolls the content, then background-position of the image should remain in place, and not scroll. Obviously in a 'regular' browser I would use background-attachment:fixed, but this doesn't seem to work on the ipad. I know position:fixed doesn't work as you might expect according to safari spec - but is there any way of achieving this?

  • Python bindings for C++ code using OpenCV giving segmentation fault

    - by lightalchemist
    I'm trying to write a python wrapper for some C++ code that make use of OpenCV but I'm having difficulties returning the result, which is a OpenCV C++ Mat object, to the python interpreter. I've looked at OpenCV's source and found the file cv2.cpp which has conversions functions to perform conversions to and fro between PyObject* and OpenCV's Mat. I made use of those conversions functions but got a segmentation fault when I tried to use them. I basically need some suggestions/sample code/online references on how to interface python and C++ code that make use of OpenCV, specifically with the ability to return OpenCV's C++ Mat to the python interpreter or perhaps suggestions on how/where to start investigating the cause of the segmentation fault. Currently I'm using Boost Python to wrap the code. Thanks in advance to any replies. The relevant code: // This is the function that is giving the segmentation fault. PyObject* ABC::doSomething(PyObject* image) { Mat m; pyopencv_to(image, m); // This line gives segmentation fault. // Some code to create cppObj from CPP library that uses OpenCV cv::Mat processedImage = cppObj->align(m); return pyopencv_from(processedImage); } The conversion functions taken from OpenCV's source follows. The conversion code gives segmentation fault at the commented line with "if (!PyArray_Check(o)) ...". static int pyopencv_to(const PyObject* o, Mat& m, const char* name = "<unknown>", bool allowND=true) { if(!o || o == Py_None) { if( !m.data ) m.allocator = &g_numpyAllocator; return true; } if( !PyArray_Check(o) ) // Segmentation fault inside PyArray_Check(o) { failmsg("%s is not a numpy array", name); return false; } int typenum = PyArray_TYPE(o); int type = typenum == NPY_UBYTE ? CV_8U : typenum == NPY_BYTE ? CV_8S : typenum == NPY_USHORT ? CV_16U : typenum == NPY_SHORT ? CV_16S : typenum == NPY_INT || typenum == NPY_LONG ? CV_32S : typenum == NPY_FLOAT ? CV_32F : typenum == NPY_DOUBLE ? CV_64F : -1; if( type < 0 ) { failmsg("%s data type = %d is not supported", name, typenum); return false; } int ndims = PyArray_NDIM(o); if(ndims >= CV_MAX_DIM) { failmsg("%s dimensionality (=%d) is too high", name, ndims); return false; } int size[CV_MAX_DIM+1]; size_t step[CV_MAX_DIM+1], elemsize = CV_ELEM_SIZE1(type); const npy_intp* _sizes = PyArray_DIMS(o); const npy_intp* _strides = PyArray_STRIDES(o); bool transposed = false; for(int i = 0; i < ndims; i++) { size[i] = (int)_sizes[i]; step[i] = (size_t)_strides[i]; } if( ndims == 0 || step[ndims-1] > elemsize ) { size[ndims] = 1; step[ndims] = elemsize; ndims++; } if( ndims >= 2 && step[0] < step[1] ) { std::swap(size[0], size[1]); std::swap(step[0], step[1]); transposed = true; } if( ndims == 3 && size[2] <= CV_CN_MAX && step[1] == elemsize*size[2] ) { ndims--; type |= CV_MAKETYPE(0, size[2]); } if( ndims > 2 && !allowND ) { failmsg("%s has more than 2 dimensions", name); return false; } m = Mat(ndims, size, type, PyArray_DATA(o), step); if( m.data ) { m.refcount = refcountFromPyObject(o); m.addref(); // protect the original numpy array from deallocation // (since Mat destructor will decrement the reference counter) }; m.allocator = &g_numpyAllocator; if( transposed ) { Mat tmp; tmp.allocator = &g_numpyAllocator; transpose(m, tmp); m = tmp; } return true; } static PyObject* pyopencv_from(const Mat& m) { if( !m.data ) Py_RETURN_NONE; Mat temp, *p = (Mat*)&m; if(!p->refcount || p->allocator != &g_numpyAllocator) { temp.allocator = &g_numpyAllocator; m.copyTo(temp); p = &temp; } p->addref(); return pyObjectFromRefcount(p->refcount); } My python test program: import pysomemodule # My python wrapped library. import cv2 def main(): myobj = pysomemodule.ABC("faces.train") # Create python object. This works. image = cv2.imread('61.jpg') processedImage = myobj.doSomething(image) cv2.imshow("test", processedImage) cv2.waitKey() if __name__ == "__main__": main()

  • Simple way to implement computer-go board in Java

    - by codingbear
    I want to make a simple Go board to design an Computer Go game. In a go game, you lie a "stone" (white or black) on a position where horizontal and vertical lines intersect. What are some simple ways to restrict users from placing their stones in other locations? Maybe I'm just not seeing a simple solution. EDIT I guess I should rephrase my question better: I want to know how to do the background image of Go board, so that I can lie my stones on the intersection of the horizontal and the vertical lines. I was thinking about getting a just regular Go board image, and when I'm actually rendering stones, I find right position of pixels to lie stones. However, that solution did not seem to be the best solution, since I need to worry about size of stone images and think about proportionality when I either expand or shrink the board window.

  • Passing a SAFEARRAY from C# to COM

    - by SlavaGu
    I use 3rd party COM to find faces in a picture. One of the methods has the following signature, from SDK: long FindMultipleFaces( IUnknown* pIDibImage, VARIANTARG* FacePositionArray ); Parameters: pIDibImage[in] - The image to search. FacePositionArray[out]- The array of FacePosition2 objects into which face information is placed. This array is in a safe array (VARIANT) of type VT_UNKNOWN. The size of the array dictates the maximum number of faces for which to search. which translates into the following C# method signature (from metadata): int FindMultipleFaces(object pIDibImage, ref object pIFacePositions); Being optimistic I call it the following way but get an exception that the memory is corrupt. The exception is thrown only when a face is present in the image. FacePosition2[] facePositions = new FacePosition2[10]; object positions = facePositions; int faceCount = FaceLocator.FindMultipleFaces(dibImage, ref positions); What's the right way to pass SAFEARRAY to unmanaged code?

  • Removing a specific XML node in TIBCO BusinessWorks

    - by sangretu
    I have a "global variable" XML schema in TIBCO BusinessWorks. It's simpler than it looks - basically just a single repeatable node. Image: Tibco globals. (old URL redacted) Various processes in the system can update this list. Checking to see if they are listed is easy: $GetVariable/subscriber-list/subscriber = $_processContext/ns:ProcessContext/ProcessId Adding themselves to the list is pretty easy too, using a Set Variable activity (see bottom half of image) But how can a process remove itself from the list? I'm sure there's a type of mapping I can use to filter out the node I want and let the rest through?

  • C# Confusing Results from Performance Test

    - by aip.cd.aish
    I am currently working on an image processing application. The application captures images from a webcam and then does some processing on it. The app needs to be real time responsive (ideally < 50ms to process each request). I have been doing some timing tests on the code I have and I found something very interesting (see below). clearLog(); log("Log cleared"); camera.QueryFrame(); camera.QueryFrame(); log("Camera buffer cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); Each time the log is called the time since the beginning of the processing is displayed. Here is my log output: [3 ms]Log cleared [41 ms]Camera buffer cleared [41 ms]Sx: 589 Sy: 414 [112 ms]Camera output acuired for processing The timings are computed using a StopWatch from System.Diagonostics. QUESTION 1 I find this slightly interesting, since when the same method is called twice it executes in ~40ms and when it is called once the next time it took longer (~70ms). Assigning the value can't really be taking that long right? QUESTION 2 Also the timing for each step recorded above varies from time to time. The values for some steps are sometimes as low as 0ms and sometimes as high as 100ms. Though most of the numbers seem to be relatively consistent. I guess this may be because the CPU was used by some other process in the mean time? (If this is for some other reason, please let me know) Is there some way to ensure that when this function runs, it gets the highest priority? So that the speed test results will be consistently low (in terms of time). EDIT I change the code to remove the two blank query frames from above, so the code is now: clearLog(); log("Log cleared"); Sensor s = t.val; log("Sx: " + S.X + " Sy: " + S.Y); Image<Bgr, Byte> cameraImage = camera.QueryFrame(); log("Camera output acuired for processing"); The timing results are now: [2 ms]Log cleared [3 ms]Sx: 589 Sy: 414 [5 ms]Camera output acuired for processing The next steps now take longer (sometimes, the next step jumps to after 20-30ms, while the next step was previously almost instantaneous). I am guessing this is due to the CPU scheduling. Is there someway I can ensure the CPU does not get scheduled to do something else while it is running through this code?

  • Nice shadow effect in text (UISegmentedControl)

    - by Matthias
    Hi, I would like to bring some color to the texts of my UISegmentedControl. So, I've searched a bit about this topic, but it seems to be not possible out-of-the-box. But I found this nice blog post (link text), how to build an image out of a custom text and then assign it to the segemented control. Works fine, but the text in these created images do not have this nice little shadow effect as the original ones. So, does anyone know, how to create such a shadow effect? I guess, Apple does the same (building an image for the text) with the standard segmenented control. Thanks for your help. Regards Matthias

  • MkMapView setRegion animation prevents touch events on Annotation Views

    - by Vlad Gurovich
    Hi there! We have a MKmapView with a bunch of Image Annotation where each Image annotation responds to touch by overriding these methods of AnnotationView subclass: -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event; -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event Our map region is updated using [MkMapView setRegion:animated:] whenever the new location is received and is far enough from the old location to make a difference. What I noticed is that if we set animated flag to YES the touches on our annotation are rarely detected(probably due to the fact that main thread is busy animating between two map regions. When we set animated flag to NO, everything is fine, but map transition may(or may not) become jerky. The question I have is whether this is an expected behavior of animated flag of [MkMapView setRegion:animated] function or whether there is a workaround for this issue. Thanks in advance

  • Oracle E-Business Suite (WebADI) integration with Oracle Open Office

    - by Harald Behnke
    Another highlight of the new Oracle Open Office Release 3.3 enterprise features is the Oracle E-Business Suite Release 12.1 (WebADI) integration. The WebADI integration in Oracle Open Office for Windows allows you to bring your Oracle E-Business Suite data into an Oracle Open Office Calc spreadsheet, where familiar data entry and modeling techniques can be used to complete your E-Business Suite tasks. You can create formatted spreadsheets on your desktop that allow you to download, view, edit, and create Oracle E-Business Suite data. Use data entry shortcuts (such as copying and pasting or dragging and dropping ranges of cells), or Calc's Open Document Format (ODF V1.2) compliant spreadsheet formulas, to calculate amounts to save time. You can combine speed and accuracy by invoking lists of values for fields within the spreadsheet. After editing the spreadsheet, you can use WebADI's validation functionality to validate the data before uploading it to the Oracle E-Business Suite. Validation messages are returned to the spreadsheet, allowing you to identify and correct invalid. This video shows a hands-on demonstration of the Oracle E-Business Suite integration: Read more about the Oracle Open Office enterprise features.

  • UIScrollView ImageView with pins on top

    - by Koppo
    To all, I have a UIScrollView which has a UIImageView. I want to show pins on this imageView. When I add pins as subviews of the ImageView everything is great except for when you zoom the scale transform happens on the pins also. I don't want this behavior and want my pins to stay the same. So I choose to add the Pins to another view which sits on top of the ImageView and is also a subview of the UIScrollView. The idea here if you will imagine is to have a layer which hovers over the map and won't scale yet show pins over where I plot them. The pin when added to the layer view don't cale if the ImageView scales. However the issue then bceomes the position of the pins doesn't match the original origin x/y as the ImageView has had a scale transform. Basically this is a custom map of a place with Pins. I am trying to have the Pins float over and not zoom in and out over my ImageView yet remember where I placed them when the zoom happens. Some code scrollView = [[UIScrollView alloc] initWithFrame:viewRect]; scrollView.delegate = self; scrollView.pagingEnabled = NO; scrollView.scrollsToTop = NO; [scrollView setBackgroundColor:[UIColor clearColor]]; scrollView.clipsToBounds = YES; // default is NO, we want to restrict drawing within our scrollview scrollView.bounces = YES; scrollView.autoresizingMask = UIViewAutoresizingFlexibleHeight; scrollView.indicatorStyle = UIScrollViewIndicatorStyleWhite; imageViewMap = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]]; imageViewMap.userInteractionEnabled = YES; viewRect = CGRectMake(0,0,imageViewMap.image.size.width,imageViewMap.image.size.height); //viewRect = CGRectMake(0,0,2976,3928); [scrollView addSubview:imageViewMap]; [scrollView setContentSize:CGSizeMake(viewRect.size.width, viewRect.size.height)]; iconsView = [[UIView alloc] initWithFrame:imageViewMap.frame]; [scrollView addSubview:iconsView]; Code to add Pin later on some event. [iconsView addSubview:pinIcon]; I am stuck in trying tp figure out how to to get my pins to hover on the map without moving when the scale happens. Thanks

  • jQuery selective hover

    - by Vitor
    Hello everyone, I'm trying to do a simple task with jQuery: I have a list of words which, when hovered, should fadeIn its corresponding image. For example: <a href="#" class="yellow">Yellow</a> <a href="#" class="blue">Blue</a> <a href="#" class="green">Green</a> <img src="yellow.jpg" class="yellow"> <img src="blue.jpg" class="blue"> <img src="green.jpg" class="green"> I'm currently doing it this way for each link/image: $('a.yellow').hover( function () { $('img.yellow').fadeIn('fast'); }, function () { $('img.yellow').fadeOut('fast'); }); The method above works fine, but as I'm still learning, I guess there's a better way to do that instead of repeating functions. Can anyone give me some light here? How can I improve this code?

  • Linear layout and custom dialog

    The button doesn't show in this layout(code below),image and textview are shown. I tried using relative layout but that doesn't help either.

  • Switching website DNS with minimal downtime

    - by Gavin
    I need to change my domain's DNS, but here in Thailand the ISPs don't follow any standards for renewing their cache of records, so it can take the full two days. I have a new website with about 1,000 members currently who are sending messages and uploading photos. I don't want both sites on the old and new server running at the same time because then I'd have to manually merge the database and transfer uploaded photos. It would be a huge pain. Both servers also a unique URL from my host, e.g. website12345.hostingcompany.com (old host) and website67890.hostingcompany.com (new host). I don't have much experience with this, but I think what I can do is on www.mysite.com, use .htaccess to do a masked redirect to the new server's URL (website67890.hostingcompany.com). Is it possible to do this and keep all URLs being masked? For example, www.mysite.com/profile/username will actually be loading website12345.hostingcompany.com/profile/username. From Google searches it sounds like this is possible, but I don't understand why this is possible due to security issues, since what's keeping people from masking their site to URLs like facebook.com? I could really use some advice here! Thanks!

  • How to speed up file transfer to/from Ubuntu Server 11.10 (wifi)

    - by Alexander
    I've been searching AU & elsewhere for the last day and a half. Haven't found an answer so I joined AU to ask for help. I'm hoping someone can point me in the right direction. Ubuntu Server 11.10 Samba VSFTPD Windows 7 PC 2 MacBook Pro - Snow Leopard/Lion 1 iMac - Lion Wireless LAN using DLink DIR-655 Link Speed: 195 Mbit/s on Mac - 54Mbps on Windows ISP Connection: Cable - 20 down/3 up No Domain Controller. All machines are members of the same workgroup. No matter how I connect I can't get better than about 700K transfer rate up/down. Mac/PC, SMB/ftp, Domain Name/Local IP I've tried different user accounts and using different folders, different volumes on the server. Nothing seems to make a difference. 700K up/down. Period. Any suggestions would be greatly appreciated. Thanks, Alexander EDIT: Using sftp now and uploading seems to peak at 980k. After about 5 minutes into a 650MB file, downloading is at 1072k and climbing about 500b/s every ten seconds. If any of that matters... I was expecting a lot faster than 1Mb tx rate. Am I off base here? EDIT: From all I've read so far, perhaps the speed isn't that bad. I only installed Ubuntu out of boredom this past weekend. The trouble is, I like it. Guess it's time to ditch the wifi and run some Cat 5.

I try with the code I am using on a UIViewController, but the view comes over all the contents of the table view, and if I add the background view in the cellForRowAtIndexPath-method, it is not showing at all. Anyone done this before or have an idea on how it can be done?

  • Drawing performance with CGImageCreateWithJPEGDataProvider?

    - by Rnegi
    I've actually curious about this for the iPhone. I am getting an MJPEG stream from a server and trying to render it natively on the iphone (without the use of safari class). Reasons for this is because the safari class while CAN render MJPEG natively, does not do so at the framerate I would like. So I tried drawing it natively, but I've come up with performance issues, namely a syncing issue between what I'm getting from the server and what I am able to draw onto the screen of the phone. (There should be a little lag, but the drift gets really bad, which is what I want to avoid). So I have a connection set up to my server and I do get the JPEGS. It's just data I insert into a NSMutableArray buffer CFMutableDataRef _t_data_ref = (CFMutableDataRef)[_buffer_array objectAtIndex:0]; //CGDataProviderRef imgDataProvider = CGDataProviderCreateWithCFData (_cf_buffer_data); CGDataProviderRef imgDataProvider = CGDataProviderCreateWithCFData(_t_data_ref); CGImageRef image = CGImageCreateWithJPEGDataProvider(imgDataProvider, NULL, true, kCGRenderingIntentDefault); CGImageRef imgRef = image; CGContextDrawImage(context, CGRectMake(0, 17, 380, 285), imgRef); CGImageRelease(image); CGDataProviderRelease(imgDataProvider); please note this is the gist of my code, but it should summarize what I am trying to accomplish with regards to drawing. Also in order to get the framerate in sync, I had to detach a separate thread that sleeps X seconds and calls [self setNeedsDisplay]. NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; // Top-level pool while(1) { //[NSThread sleepForTimeInterval:TIMER_REFRESH_VALUE]; //sleep(unsigned int ); usleep(MICRO_REFRESH_VALUE); if ([_buffer_array count] > 10) { //NSLog(@"stuff %d", [_buffer_array count]); //[self setNeedsDisplay]; [self performSelectorOnMainThread:@selector(setNeedsDisplay) withObject:nil waitUntilDone:NO]; } } [pool release]; // Release the objects in the pool. My buffer of jpeg data actually fills up quite quick, but I can't seem to actually consume what i'm getting at the same rate, actually much slower. Are there any documents that can describe what kind of performance tuning I can do to make it go faster when rendering the JPEG to the screen? Or am I kind of stuck here? Thanks!

  • Any way to simulate MouseOver in WPF

    - by jpierson
    I'm working on a link control in WPF which fits the text with icon links case in the Windows UX Guide. What I want is to have some text within a hyperlink that appears to the right of some image. In my case I started off by using a TextBlock that contained a Hyperlink which then contained my image and some text. <TextBlock> <Hyperlink> <Rectangle Height="16" Width="16" Fill="{StaticResource MyIconBrush}" Stretch="UniformToFill" VerticalAlignment="Center" HorizontalAlignment="Left" /> <Run>My link text</Run> </Hyperlink> </TextBlock> The problem with this however was that the image being taller than my text produced an effect where the text was aligned to the bottom. Unfortunately I haven't found any way to control the vertical alignment within the TextBlock or within the Hyperlink so I've resorted to attempting an alternative layout where the Hyperlink and the Rectangle that represent my vector icon are separated in order to get them to align properly like shown below. <TextBlock> <Hyperlink> <StackPanel Orientation="Horizontal"> <Rectangle Height="16" Width="16" Fill="{StaticResource MyIconBrush}" Stretch="UniformToFill" VerticalAlignment="Center" HorizontalAlignment="Left" /> <TextBlock VerticalAlignment="Center"><Hyperlink>My link text<Hyperlink></TextBlock> </StackPanel> </Hyperlink> </TextBlock> The problem with this however is that now that my Icon and my Hyperlink are separated I don't get my MouseOver appearance of my link when I the mouse is over my icon and vise-versa. So this got me to thinking, how do I simulate MouseOver for a given control such with a checkbox where you get the MouseOver effect on the box when you actually mouse over it's associated text. I know in the HTML world the label element has a for attribute that can be used to specify which control it is labeling which will basically do what I'm looking for. Also I can imagine that in other scenarios it may be nice to have a label that when you mouse over shows a corresponding text box as if the mouse is over it and possibly when clicked focus is given to the corresponding text box as well. For now though I'm interested mainly in how to to get a label or label like element in WPF to act as a proxy for a given control in terms of it's MouseOver state. Also I would like to do this purely in XAML if possible.

  • SVN Export or Recursively Remove .SVN Folders

    - by Ben Griswold
    I shared this script with a coworker yesterday. It doesn’t do much; it recursively deletes .svn folders from a source tree.  It comes in handy if you want to share your codebase or you get in a terrible spot with SVN and you just want to start all over. Just blow away all svn artifacts and use your mulligan. It’s true. You can nearly get the same result using the SVN export command which copies your source sans the .svn folders to an alternate location.  The catch is an export only includes those files/folders which exist under version control.  If you want a clean copy of your source – versioned or not – export just might not do. The contents of the .cmd file include the following: for /f "tokens=* delims=" %%i in (’dir /s /b /a:d *.svn’) do ( rd /s /q "%%i" ) Just download and drop the unzipped “SVN Cleanup.cmd” file into the root of the project, execute and away you go.  If you search around enough, I know you can find similar scripts and approaches elsewhere, but I’m still uploading my script for completeness and future reference.

  • OpenCV rotation solution?

    - by sundowatch
    I am using those codes for rotation transforming an image, but it doesn't work. Waht is the problem? IplImage *src = cvLoadImage("image.jpg",1), *dst = cvCloneImage(src); CvMat *rotation_mat = cvCreateMat(2,3,CV_32FC1); CvPoint2D32f center = cvPoint2D32f(src->width/2 ,src->height/2); cvZero(dst); double angle = -50.0, scale = 0.6; cv2DRotationMatrix(center, angle, scale, rotation_mat); cvWarpAffine(src, dst, rotation_mat); cvNamedWindow("rotation"); cvShowImage("rotation",dst); cvWaitKey(0); cvReleaseMat(&rotation_mat); cvReleaseImage(&src); cvReleaseImage(&dst); cvDestroyAllWindows(); return 0;
