  • NSArray in NSArray do not return the image I want

    - by Tibi
    Hi there, I've got a code snippet here that I can't make working. NSUInteger i; //NSMutableArray *textures = [[NSMutableArray alloc] initWithCapacity:kNumTextures]; //NSMutableArray *texturesHighlighted = [[NSMutableArray alloc] initWithCapacity:kNumTextures]; NSMutableArray *textures= [[NSMutableArray alloc] init]; for (i = 1; i <= kNumTextures; i++) { NSString *imageName = [NSString stringWithFormat:@"texture%d.png", i]; NSString *imageNameHighlighted = [NSString stringWithFormat:@"texture%d_select.png", i]; UIImage *image = [UIImage imageNamed:imageName]; UIImage *imageHighlighted = [UIImage imageNamed:imageNameHighlighted]; //NSArray *pics = [[NSArray alloc] initWithObjects:(UIImage)image,(UIImage)imageHighlighted,nil]; NSArray *pics = [NSArray arrayWithObjects:image,imageHighlighted,nil]; [textures addObject:pics]; [pics release]; } //select randomly the position of the picture that will be represented twice on the board NSInteger randomTexture = arc4random()%([textures count]+1); //extract image corresponding to the randomly selected index //remove corresponding pictures from textures array NSArray *coupleTexture = [textures objectAtIndex:randomTexture]; [textures removeObjectAtIndex:randomTexture]; //create the image array containing 1 couple + all other pictures NSMutableArray *texturesBoard = [[NSMutableArray alloc] initWithCapacity:kNumPotatoes]; [texturesBoard addObject:coupleTexture]; [texturesBoard addObject:coupleTexture]; [coupleTexture release]; NSArray *pics = [[NSArray alloc] init]; for (pics in textures) { [texturesBoard addObject:pics]; } [pics release]; //shuffle the textures //[texturesBoard shuffledMutableArray]; //Array with masks NSMutableArray *masks= [[NSMutableArray alloc] init]; for (i = 1; i <= kNumMasks; i++) { NSString *maskName = [NSString stringWithFormat:@"mask%d.png", i]; UIImage *mask = [UIImage imageNamed:maskName]; //NSArray *pics = [[NSArray alloc] initWithObjects:mask,nil]; [masks addObject:mask]; //[pics release]; [maskName release]; [mask release]; } //Now mask all images in texturesBoard NSMutableArray *list = [[NSMutableArray alloc] init]; for (i = 0; i <= kNumMasks-1; i++) { //take on image couple from textures NSArray *imgArray = [texturesBoard objectAtIndex:i]; UIImage *mask = [masks objectAtIndex:i]; //mask it with the mask un the array at corresponding index UIImage *img1 =(UIImage *) [imgArray objectAtIndex:0]; UIImage *img2 =(UIImage *) [imgArray objectAtIndex:1]; UIImage *picsMasked = [self maskImage:(UIImage *)img1 withMask:(UIImage *)mask]; UIImage *picsHighlightedMasked = [self maskImage:(UIImage *)img2 withMask:(UIImage *)mask]; //Init image with highlighted status TapDetectingImageView *imageView = [[TapDetectingImageView alloc] initWithImage:picsMasked imageHighlighted:picsHighlightedMasked]; [list addObject:imageView]; } The problem here is that : img1 and img2, are not images but rather NSArray with multiple entries. Ican't figure why... dos any fresh spirit here could provide me with some clue to fix. maaany thanks.

  • Interactive Data Language, IDL: Does anybody care?

    - by Alex
    Anyone use a language called Interactive Data Language, IDL? It is popular with scientists. I think it is a poor language because it is proprietary (every terminal running it has to have an expensive license purchased) and it has minimal support (try searching for IDL, the language, right now on stack) . I am trying to convince my colleagues to stop using it and learn C/C++/Python/Fortran/Java/Ruby. Does anybody know about or even care about IDL enough to have opinions on it? What do you think of it? Should I tell my colleagues to stop wasting their time on it now? How can I convince them? Edit: People are getting the impression that I don't know or use IDL. Also, I said IDL has minimal support which is true in one sense, so I must clarify that the scientific libraries are indeed large. I use IDL all the time, but this is exactly the problem: I am only using IDL because colleagues use it. There is a file format IDL uses, the .sav, which can only be opened in IDL. So I must use IDL to work with this data and transfer the data back to colleagues, but I know I would be more efficient in another language. This is like someone sending you a microsoft word file in an email attachment and if you don't understand how wrong that is then you probably write too many words not enough code and you bought microsoft word. Edit: As an alternative to IDL Python is popular. Here is a list of The Pros of IDL (and the cons) from AstroBetter: Pros of IDL Mature many numerical and astronomical libraries available Wide astronomical user base Numerical aspect well integrated with language itself Many local users with deep experience Faster for small arrays Easier installation Good, unified documentation Standard GUI run/debug tool (IDLDE) Single widget system (no angst about which to choose or learn) SAVE/RESTORE capability Use of keyword arguments as flags more convenient Cons of IDL Narrow applicability, not well suited to general programming Slower for large arrays Array functionality less powerful Table support poor Limited ability to extend using C or Fortran, such extensions hard to distribute and support Expensive, sometimes problem collaborating with others that don’t have or can’t afford licenses. Closed source (only RSI can fix bugs) Very awkward to integrate with IRAF tasks Memory management more awkward Single widget system (useless if working within another framework) Plotting: Awkward support for symbols and math text Many font systems, portability issues (v5.1 alleviates somewhat) not as flexible or as extensible plot windows not intrinsically interactive (e.g., pan & zoom) Pros of Python Very general and powerful programming language, yet easy to learn. Strong, but optional, Object Oriented programming support Very large user and developer community, very extensive and broad library base Very extensible with C, C++, or Fortran, portable distribution mechanisms available Free; non-restrictive license; Open Source Becoming the standard scripting language for astronomy Easy to use with IRAF tasks Basis of STScI application efforts More general array capabilities Faster for large arrays, better support for memory mapping Many books and on-line documentation resources available (for the language and its libraries) Better support for table structures Plotting framework (matplotlib) more extensible and general Better font support and portability (only one way to do it too) Usable within many windowing frameworks (GTK, Tk, WX, Qt…) Standard plotting functionality independent of framework used plots are embeddable within other GUIs more powerful image handling (multiple simultaneous LUTS, optional resampling/rescaling, alpha blending, etc) Support for many widget systems Strong local influence over capabilities being developed for Python Cons of Python More items to install separately Not as well accepted in astronomical community (but support clearly growing) Scientific libraries not as mature: Documentation not as complete, not as unified Not as deep in astronomical libraries and utilities Not all IDL numerical library functions have corresponding functionality in Python Some numeric constructs not quite as consistent with language (or slightly less convenient than IDL) Array indexing convention “backwards” Small array performance slower No standard GUI run/debug tool Support for many widget systems (angst regarding which to choose) Current lack of function equivalent to SAVE/RESTORE in IDL matplotlib does not yet have equivalents for all IDL 2-D plotting capability (e.g., surface plots) Use of keyword arguments used as flags less convenient Plotting: comparatively immature, still much development going on missing some plot type (e.g., surface) 3-d capability requires VTK (though matplotlib has some basic 3-d capability)

  • unsigned char* buffer (FreeType2 Bitmap) to System::Drawing::Bitmap.

    - by Dennis Roche
    Hi, I'm trying to convert a FreeType2 bitmap to a System::Drawing::Bitmap in C++/CLI. FT_Bitmap has a unsigned char* buffer that contains the data to write. I have got somewhat working save it disk as a *.tga, but when saving as *.bmp it renders incorrectly. I believe that the size of byte[] is incorrect and that my data is truncated. Any hints/tips/ideas on what is going on here would be greatly appreciated. Links to articles explaining byte layout and pixel formats etc. would be helpful. Thanks!! C++/CLI code. FT_Bitmap *bitmap = &face->glyph->bitmap; int width = (face->bitmap->metrics.width / 64); int height = (face->bitmap->metrics.height / 64); // must be aligned on a 32 bit boundary or 4 bytes int depth = 8; int stride = ((width * depth + 31) & ~31) >> 3; int bytes = (int)(stride * height); // as *.tga void *buffer = bytes ? malloc(bytes) : NULL; if (buffer) { memset(buffer, 0, bytes); for (int i = 0; i < glyph->rows; ++i) memcpy((char *)buffer + (i * width), glyph->buffer + (i * glyph->pitch), glyph->pitch); WriteTGA("Test.tga", buffer, width, height); } // as *.bmp array<Byte>^ values = gcnew array<Byte>(bytes); Marshal::Copy((IntPtr)glyph->buffer, values, 0, bytes); Bitmap^ systemBitmap = gcnew Bitmap(width, height, PixelFormat::Format24bppRgb); // create bitmap data, lock pixels to be written. BitmapData^ bitmapData = systemBitmap->LockBits(Rectangle(0, 0, width, height), ImageLockMode::WriteOnly, bitmap->PixelFormat); Marshal::Copy(values, 0, bitmapData->Scan0, bytes); systemBitmap->UnlockBits(bitmapData); systemBitmap->Save("Test.bmp"); Reference, FT_Bitmap typedef struct FT_Bitmap_ { int rows; int width; int pitch; unsigned char* buffer; short num_grays; char pixel_mode; char palette_mode; void* palette; } FT_Bitmap; Reference, WriteTGA bool WriteTGA(const char *filename, void *pxl, uint16 width, uint16 height) { FILE *fp = NULL; fopen_s(&fp, filename, "wb"); if (fp) { TGAHeader header; memset(&header, 0, sizeof(TGAHeader)); header.imageType = 3; header.width = width; header.height = height; header.depth = 8; header.descriptor = 0x20; fwrite(&header, sizeof(header), 1, fp); fwrite(pxl, sizeof(uint8) * width * height, 1, fp); fclose(fp); return true; } return false; } Update FT_Bitmap *bitmap = &face->glyph->bitmap; // stride must be aligned on a 32 bit boundary or 4 bytes int depth = 8; int stride = ((width * depth + 31) & ~31) >> 3; int bytes = (int)(stride * height); target = gcnew Bitmap(width, height, PixelFormat::Format8bppIndexed); // create bitmap data, lock pixels to be written.

  • Managing highly repetitive code and documentation in Java

    - by polygenelubricants
    Highly repetitive code is generally a bad thing, and there are design patterns that can help minimize this. However, sometimes it's simply inevitable due to the constraints of the language itself. Take the following example from java.util.Arrays: /** * Assigns the specified long value to each element of the specified * range of the specified array of longs. The range to be filled * extends from index <tt>fromIndex</tt>, inclusive, to index * <tt>toIndex</tt>, exclusive. (If <tt>fromIndex==toIndex</tt>, the * range to be filled is empty.) * * @param a the array to be filled * @param fromIndex the index of the first element (inclusive) to be * filled with the specified value * @param toIndex the index of the last element (exclusive) to be * filled with the specified value * @param val the value to be stored in all elements of the array * @throws IllegalArgumentException if <tt>fromIndex &gt; toIndex</tt> * @throws ArrayIndexOutOfBoundsException if <tt>fromIndex &lt; 0</tt> or * <tt>toIndex &gt; a.length</tt> */ public static void fill(long[] a, int fromIndex, int toIndex, long val) { rangeCheck(a.length, fromIndex, toIndex); for (int i=fromIndex; i<toIndex; i++) a[i] = val; } The above snippet appears in the source code 8 times, with very little variation in the documentation/method signature but exactly the same method body, one for each of the root array types int[], short[], char[], byte[], boolean[], double[], float[], and Object[]. I believe that unless one resorts to reflection (which is an entirely different subject in itself), this repetition is inevitable. I understand that as a utility class, such high concentration of repetitive Java code is highly atypical, but even with the best practice, repetition does happen! Refactoring doesn't always work because it's not always possible (the obvious case is when the repetition is in the documentation). Obviously maintaining this source code is a nightmare. A slight typo in the documentation, or a minor bug in the implementation, is multiplied by however many repetitions was made. In fact, the best example happens to involve this exact class: Google Research Blog - Extra, Extra - Read All About It: Nearly All Binary Searches and Mergesorts are Broken (by Joshua Bloch, Software Engineer) The bug is a surprisingly subtle one, occurring in what many thought to be just a simple and straightforward algorithm. // int mid =(low + high) / 2; // the bug int mid = (low + high) >>> 1; // the fix The above line appears 11 times in the source code! So my questions are: How are these kinds of repetitive Java code/documentation handled in practice? How are they developed, maintained, and tested? Do you start with "the original", and make it as mature as possible, and then copy and paste as necessary and hope you didn't make a mistake? And if you did make a mistake in the original, then just fix it everywhere, unless you're comfortable with deleting the copies and repeating the whole replication process? And you apply this same process for the testing code as well? Would Java benefit from some sort of limited-use source code preprocessing for this kind of thing? Perhaps Sun has their own preprocessor to help write, maintain, document and test these kind of repetitive library code? A comment requested another example, so I pulled this one from Google Collections: com.google.common.base.Predicates lines 276-310 (AndPredicate) vs lines 312-346 (OrPredicate). The source for these two classes are identical, except for: AndPredicate vs OrPredicate (each appears 5 times in its class) "And(" vs Or(" (in the respective toString() methods) #and vs #or (in the @see Javadoc comments) true vs false (in apply; ! can be rewritten out of the expression) -1 /* all bits on */ vs 0 /* all bits off */ in hashCode() &= vs |= in hashCode()

  • Optimal storage of data structure for fast lookup and persistence

    - by Mikael Svenson
    Scenario I have the following methods: public void AddItemSecurity(int itemId, int[] userIds) public int[] GetValidItemIds(int userId) Initially I'm thinking storage on the form: itemId -> userId, userId, userId and userId -> itemId, itemId, itemId AddItemSecurity is based on how I get data from a third party API, GetValidItemIds is how I want to use it at runtime. There are potentially 2000 users and 10 million items. Item id's are on the form: 2007123456, 2010001234 (10 digits where first four represent the year). AddItemSecurity does not have to perform super fast, but GetValidIds needs to be subsecond. Also, if there is an update on an existing itemId I need to remove that itemId for users no longer in the list. I'm trying to think about how I should store this in an optimal fashion. Preferably on disk (with caching), but I want the code maintainable and clean. If the item id's had started at 0, I thought about creating a byte array the length of MaxItemId / 8 for each user, and set a true/false bit if the item was present or not. That would limit the array length to little over 1mb per user and give fast lookups as well as an easy way to update the list per user. By persisting this as Memory Mapped Files with the .Net 4 framework I think I would get decent caching as well (if the machine has enough RAM) without implementing caching logic myself. Parsing the id, stripping out the year, and store an array per year could be a solution. The ItemId - UserId[] list can be serialized directly to disk and read/write with a normal FileStream in order to persist the list and diff it when there are changes. Each time a new user is added all the lists have to updated as well, but this can be done nightly. Question Should I continue to try out this approach, or are there other paths which should be explored as well? I'm thinking SQL server will not perform fast enough, and it would give an overhead (at least if it's hosted on a different server), but my assumptions might be wrong. Any thought or insights on the matter is appreciated. And I want to try to solve it without adding too much hardware :) [Update 2010-03-31] I have now tested with SQL server 2008 under the following conditions. Table with two columns (userid,itemid) both are Int Clustered index on the two columns Added ~800.000 items for 180 users - Total of 144 million rows Allocated 4gb ram for SQL server Dual Core 2.66ghz laptop SSD disk Use a SqlDataReader to read all itemid's into a List Loop over all users If I run one thread it averages on 0.2 seconds. When I add a second thread it goes up to 0.4 seconds, which is still ok. From there on the results are decreasing. Adding a third thread brings alot of the queries up to 2 seonds. A forth thread, up to 4 seconds, a fifth spikes some of the queries up to 50 seconds. The CPU is roofing while this is going on, even on one thread. My test app takes some due to the speedy loop, and sql the rest. Which leads me to the conclusion that it won't scale very well. At least not on my tested hardware. Are there ways to optimize the database, say storing an array of int's per user instead of one record per item. But this makes it harder to remove items.

  • Reading email address from contacts fails with weird memory issue - Solved

    - by CapsicumDreams
    Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount > 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on? Solution: It turned out that I wasn't storing the ABRecordRef personDealingWith var correctly. I'm still not sure how to do that properly, but instead of having the functionality in another routine (performed later), I'm now doing the grunt-work in the delegate method, and using the derived results at my leisure. The new (working) routine: - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person { // as soon as they select someone, return personDealingWithFullName = (NSString *)ABRecordCopyCompositeName(person); personDealingWithFirstName = (NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty); // construct array of emails [personDealingWithEmails removeAllObjects]; ABMutableMultiValueRef multi = ABRecordCopyValue(person, kABPersonEmailProperty); if (ABMultiValueGetCount(multi) > 0) { // collect all emails in array for (CFIndex i = 0; i < ABMultiValueGetCount(multi); i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [personDealingWithEmails addObject:(NSString *)emailRef]; CFRelease(emailRef); } } CFRelease(multi); return NO; }

  • JAVA BubbleSort Output Plotting

    I'm not sure how to plot the output I get with my run time results for BubbleSort. Here's the thing: I've written a working BubbleSort algorithm that does exactly as it should. But I wish to plot the output, to show the following: Best Case, Worst Case, Average Case ... How would I go about plotting it on a graph? Here is the code: public class BubbleSort { static double bestTime = 10000000, worstTime = 0; public static void main(String[] args) { int BubArray[] = new int[]{13981, 6793, 2662, 10986, 733, ... #1000 integers}; System.out.println("Unsorted List Before Bubble Sort"); for(int a = 0; a < BubArray.length; a++){ System.out.print(BubArray[a] + " "); } System.out.println("\n Bubble Sort Execution ..."); for(int i=0; i<10000;i++) { bubbleSortTimeTaken(BubArray, i); } int itrs = bubbleSort(BubArray); System.out.println(""); System.out.println("Array After Bubble Sort"); System.out.println("Moves Taken for Sort : " + itrs + " Moves."); System.out.println("BestTime: " + bestTime + " WorstTime: " + worstTime); System.out.print("Sorted Array: \n"); for(int a = 0; a < BubArray.length; a++){ System.out.print(BubArray[a] + " "); } } private static int bubbleSort(int[] BubArray) { int z = BubArray.length; int temp = 0; int itrs = 0; for(int a = 0; a < z; a++){ for(int x=1; x < (z-a); x++){ if(BubArray[x-1] > BubArray[x]){ temp = BubArray[x-1]; BubArray[x-1] = BubArray[x]; BubArray[x] = temp; } itrs++; } } return itrs; } public static void bubbleSortTimeTaken(int[] BubArray, int n) { long startTime = System.nanoTime(); bubbleSort(BubArray); double timeTaken = (System.nanoTime() - startTime)/1000000d; if (timeTaken > 0) { worstTime = timeTaken; } else if (timeTaken < bestTime) { bestTime = timeTaken; } System.out.println(n + "," + timeTaken); } } The output are as the following ( execution number, time (nano/10^6): Unsorted List Before Bubble Sort 13981 6793 2662 .... #1000 integers Bubble Sort Execution ... 0, 18.319891 1, 4.728978 2, 3.670697 3, 3.648922 4, 4.161576 5, 3.824369 .... 9995, 4.331423 9996, 3.692473 9997, 3.709893 9998, 6.16055 9999, 4.32209 Array After Bubble Sort Moves Taken for Sort : 541320 Moves.

Any help would be appreciated, thanks.

  • php soapclient responds as 'null' but xml response is ok using __getLastResponse

    - by Roger S
    I'm looking for help with a php soapclient call: The call is to a remote panel and I want to pull off the log data. There are various services published via the WSDL and I am able to use several with no issues. Here's the list: array(12) { [0]=> string(77) "GetGPTimerChannelsResponse GetGPTimerChannels(GetGPTimerChannels $parameters)" [1]=> string(74) "GetGPTimerChannelResponse GetGPTimerChannel(GetGPTimerChannel $parameters)" [2]=> string(74) "SetGPTimerChannelResponse SetGPTimerChannel(SetGPTimerChannel $parameters)" [3]=> string(47) "GetSlaveResponse GetSlave(GetSlave $parameters)" [4]=> string(71) "GetLogDataInlineResponse GetLogDataInline(GetLogDataInline $parameters)" [5]=> string(71) "GetLogItemInlineResponse GetLogItemInline(GetLogItemInline $parameters)" [6]=> string(59) "GetAlarmListResponse GetAlarmList(GetAlarmList $parameters)" [7]=> string(50) "GetSyslogResponse GetSyslog(GetSyslog $parameters)" [8]=> string(47) "SetSlaveResponse SetSlave(SetSlave $parameters)" [9]=> string(53) "GetVersionResponse GetVersion(GetVersion $parameters)" [10]=> string(53) "GetTDBInfoResponse GetTDBInfo(GetTDBInfo $parameters)" [11]=> string(53) "GetLogItemResponse GetLogItem(GetLogItem $parameters)" } I am trying to use the GetLogDataInline service which requires four parameters - these I'm passing as an array and all seems OK when doing the connection (the request/response takes around 30 seconds to process). When I look at a var_dump / print_r of the result, it returns NULL, whereas when I do a call to the __getLastResponse all of the data I need to populate my local database is there.

  • matplotlib and python multithread file processing

    - by Napseis
    I have a large number of files to process. I have written a script that get, sort and plot the datas I want. So far, so good. I have tested it and it gives the desired result. Then I wanted to do this using multithreading. I have looked into the doc and examples on the internet, and using one thread in my program works fine. But when I use more, at some point I get random matplotlib error, and I suspect some conflict there, even though I use a function with names for the plots, and iI can't see where the problem could be.

  • How color attributes work in VBO?

    - by Jayesh
    I am coding to OpenGL ES 2.0 (Webgl). I am using VBOs to draw primitives. I have vertex array, color array and array of indices. I have looked at sample codes, books and tutorial, but one thing I don't get - if color is defined per vertex how does it affect the polygonal surfaces adjacent to those vertices? (I am a newbie to OpenGL(ES)) I will explain with an example. I have a cube to draw. From what I read in OpenGLES book, the color is defined as an vertex attribute. In that case, if I want to draw 6 faces of the cube with 6 different colors how should I define the colors. The source of my confusion is: each vertex is common to 3 faces, then how will it help defining a color per vertex? (Or should the color be defined per index?). The fact that we need to subdivide these faces into triangles, makes it harder for me to understand how this relationship works. The same confusion goes for edges. Instead of drawing triangles, let's say I want to draw edges using LINES primitives. Each edge of different color. How am I supposed to define color attributes in that case? I have seen few working examples. Specifically this tutorial: http://learningwebgl.com/blog/?p=370 I see how color array is defined in the above example to draw a cube with 6 different colored faces, but I don't understand why is defined that way. (Why is each color copied 4 times into unpackedColors for instance?) Can someone explain how color attributes work in VBO? [The link above seems inaccessible, so I will post the relevant code here] cubeVertexPositionBuffer = gl.createBuffer(); gl.bindBuffer(gl.ARRAY_BUFFER, cubeVertexPositionBuffer); vertices = [ // Front face -1.0, -1.0, 1.0, 1.0, -1.0, 1.0, 1.0, 1.0, 1.0, -1.0, 1.0, 1.0, // Back face -1.0, -1.0, -1.0, -1.0, 1.0, -1.0, 1.0, 1.0, -1.0, 1.0, -1.0, -1.0, // Top face -1.0, 1.0, -1.0, -1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0, -1.0, // Bottom face -1.0, -1.0, -1.0, 1.0, -1.0, -1.0, 1.0, -1.0, 1.0, -1.0, -1.0, 1.0, // Right face 1.0, -1.0, -1.0, 1.0, 1.0, -1.0, 1.0, 1.0, 1.0, 1.0, -1.0, 1.0, // Left face -1.0, -1.0, -1.0, -1.0, -1.0, 1.0, -1.0, 1.0, 1.0, -1.0, 1.0, -1.0, ]; gl.bufferData(gl.ARRAY_BUFFER, new WebGLFloatArray(vertices), gl.STATIC_DRAW); cubeVertexPositionBuffer.itemSize = 3; cubeVertexPositionBuffer.numItems = 24; cubeVertexColorBuffer = gl.createBuffer(); gl.bindBuffer(gl.ARRAY_BUFFER, cubeVertexColorBuffer); var colors = [ [1.0, 0.0, 0.0, 1.0], // Front face [1.0, 1.0, 0.0, 1.0], // Back face [0.0, 1.0, 0.0, 1.0], // Top face [1.0, 0.5, 0.5, 1.0], // Bottom face [1.0, 0.0, 1.0, 1.0], // Right face [0.0, 0.0, 1.0, 1.0], // Left face ]; var unpackedColors = [] for (var i in colors) { var color = colors[i]; for (var j=0; j < 4; j++) { unpackedColors = unpackedColors.concat(color); } } gl.bufferData(gl.ARRAY_BUFFER, new WebGLFloatArray(unpackedColors), gl.STATIC_DRAW); cubeVertexColorBuffer.itemSize = 4; cubeVertexColorBuffer.numItems = 24; cubeVertexIndexBuffer = gl.createBuffer(); gl.bindBuffer(gl.ELEMENT_ARRAY_BUFFER, cubeVertexIndexBuffer); var cubeVertexIndices = [ 0, 1, 2, 0, 2, 3, // Front face 4, 5, 6, 4, 6, 7, // Back face 8, 9, 10, 8, 10, 11, // Top face 12, 13, 14, 12, 14, 15, // Bottom face 16, 17, 18, 16, 18, 19, // Right face 20, 21, 22, 20, 22, 23 // Left face ] gl.bufferData(gl.ELEMENT_ARRAY_BUFFER, new WebGLUnsignedShortArray(cubeVertexIndices), gl.STATIC_DRAW); cubeVertexIndexBuffer.itemSize = 1; cubeVertexIndexBuffer.numItems = 36;

  • How can I implement the Gale-Shapley stable marriage algorithm in Perl?

    - by srk
    Problem : We have equal number of men and women.each men has a preference score toward each woman. So do the woman for each man. each of the men and women have certain interests. Based on the interest we calculate the preference scores. So initially we have an input in a file having x columns. First column is the person(men/woman) id. id are nothing but 0.. n numbers.(first half are men and next half woman) the remaining x-1 columns will have the interests. these are integers too. now using this n by x-1 matrix... we have come up with a n by n/2 matrix. the new matrix has all men and woman as their rows and scores for opposite sex in columns. We have to sort the scores in descending order, also we need to know the id of person related to the scores after sorting. So here i wanted to use hash table. once we get the scores we need to make up pairs.. for which we need to follow some rules. My trouble is with the second matrix of n by n/2 that needs to give information of which man/woman has how much preference on a woman/man. I need these scores sorted so that i know who is the first preferred woman/man, 2nd preferred and so on for a man/woman. I hope to get good suggestions on the data structures i use.. I prefer php or perl. Thank you in advance Hey guys this is not an home work. This a little modified version of stable marriage algorithm. I have working solution. I am only working on optimizing my code. more info: It is very similar to stable marriage problem but here we need to calculate the scores based on the interests they share. So i have implemented it as the way you see in the wiki page http://en.wikipedia.org/wiki/Stable_marriage_problem. my problem is not solving the problem. i solved it and can run it. I am just trying to have a better solution. so i am asking suggestions on the type of data structure to use. Conceptually I tried using an array of hashes. where the array index give the person id and the hash in it gives the id's <= score's in sorted manner. I initially start with an array of hashes. now i sort the hashes on values, but i could not store the sorted hashes back in an array.So just stored the keys after sorting and used these to get the values from my initial unsorted hashes. Can we store the hashes after sorting ? Can you suggest a better structure ?

  • jQuery .live fireing multiple times!

    - by cstrzelc
    Greetings Guru's, This is a little hard to explain, but I'll give it a shot. I have a quick question regarding to the .live() function in JQuery. I'm going to simplify the example here. I have a page "index.php" that has a container "#display_files_container" which is populated with anchor links that are generated dynamically by a different page "process.php". The links are loaded into that same <div> when those links are selected based on the attributes of that link. See Examples: INDEX.PHP <html> <head><title>index.php</title> <!-- this function below loads process.php and passes it the dirid variable via post. I then use this post variable inside of process.php to pull other links from the database --> <script language="text/javascript"> $('.directory').live("click", function() { $('#display_files_container').load('plugins/project_files/process.php', {dirid: $(this).attr('dirid')}); }); </script> </head> <?php /*This code initial populates the link array so we have the first links populated before the users clicks for the first time*/ some code to fetch the $current_directory_list array from the database initially.... >? <body> <div id='display_files_container'> <?php /*Cycle through the array and echo out all the links which have been pulled from DB*/ for($i=0;$i<$current_directory_count;$i++) { echo "<a href='#' class='directory' dirid='".$current_directory_list[$i]['id']." '>".$current_directory_list[$i]['directory_name']. "</a> "; } ?> </div> </body> </html> PROCESS.PHP this file includes code to populate the $current_directory_list[] array from the database based on the post variable "$_POST['dirid']" that was sent from the .click() method in index.php. It then echo's the results out and we display them in the #display_files_container container. When you click on those links the process repeats. This works..... you can click though the directory tree and it loads the new links every time. However, it seems to want to .load() the process.php file many times over for one click. The number of times process.php is loaded seems to increase the more the links are clicked. So for example you can click on a link and firebug reports that process.php was loaded 23 times..... Eventually I would imagine I would record a stackoverflow. Please let me know if you have any ideas. Are there any ways that I can assure that .live() loads the process.php file only once? Thanks, -cs

  • CakeDC Users Plugin - I Can't Send Emails

    - by JimBadger
    I apologise for the rambling nature of this question, please bear with me and I'll provide all the extra info needed for you to stop me going mad from failing at something that looks inherently very straightforward... I've just installed CakePHP 2.2, and the first thing I've done is add the cakeDC Users plugin. It's all working, apart from sending an email verification when a user registers. I've tried so many combinations of different things in email.php, that I have now utterly got my knickers in a twist. Whatever I do, when the verification email should be sent, all I get is: No connection could be made because the target machine actively refused it. My email.php currently looks like this: class EmailConfig { public $default = array( 'transport' => 'Smtp', 'from' => '[email protected]', //'charset' => 'utf-8', //'headerCharset' => 'utf-8', ); public $smtp = array( 'transport' => 'Smtp', 'from' => array('Blah <[email protected]>' => 'Chimp'), 'host' => 'ssl://smtp.gmail.com', 'port' => 465, 'timeout' => 30, 'username' => '[email protected]', 'password' => 'secret', 'client' => null, 'log' => false, //'charset' => 'utf-8', //'headerCharset' => 'utf-8', ); public $fast = array( 'from' => '[email protected]', 'sender' => null, 'to' => null, 'cc' => null, 'bcc' => null, 'replyTo' => null, 'readReceipt' => null, 'returnPath' => null, 'messageId' => true, 'subject' => null, 'message' => null, 'headers' => null, 'viewRender' => null, 'template' => false, 'layout' => false, 'viewVars' => null, 'attachments' => null, 'emailFormat' => null, 'transport' => 'Smtp', 'host' => 'blah.net', 'port' => 25, 'timeout' => 30, 'username' => 'user', 'password' => 'secret', 'client' => null, 'log' => true, //'charset' => 'utf-8', //'headerCharset' => 'utf-8', ); } How do I get cakeDC Users plugin to just send a non-SMTP email? Or do I have to use, for example, my Gmail details? But, if I do have to go down the SMTP route, what is wrong with the above? Other info: I'm using the latest version of XAMPP and my PHP install is ssl enabled.

  • PHP returning part of the code document

    - by The.Anti.9
    I have a PHP page that does a couple of different things depending on what action is set to in the GET data. Depending, it is supposed to return some JSON, but instead of doing anything it is supposed to it returns the bottom half of the code document itself, starting in the middle of the line. Heres the snippit from where it starts: ... } elseif ($_GET['action'] == 'addtop') { if (!isset($_GET['pname']) || !isset($_GET['url']) || !isset($_GET['artist']) || !isset($_GET['album']) || !isset($_GET['file'])) { die('Error: Incomplete data!'); } if (!file_exists($_GET['pname'].".txt")) { die('Error: No such playlist!'); } $plist = json_decode(file_get_contents($_GET['pname'].".txt"), true); $fh = fopen($_GET['pname'].".txt", 'w') or die('Could not open playlist!'); array_push($plist, array("artist" => $_GET['artist'], "album" => $_GET['album'], "file" => $_GET['file'], "url" => $_GET['url'])); fwrite($fh,json_encode($plist)); } elseif ($_GET['action'] == 'delfromp') { ... And here is what I get when I go to the page: $_GET['artist'], "album" = $_GET['album'], "file" = $_GET['file'], "url" = $_GET['url'])); fwrite($fh,json_encode($plist)); } elseif ($_GET['action'] == 'delfromp') { if (!isset($_GET['pname']) || !isset($_GET['id'])) { die('Error: Incomplete data!'); } if (!file_exists($_GET['pname'].".txt")) { die('Error: No such playlist!'); } $plist = json_decode(file_get_contents($_GET['pname'].".txt"), true); $fh = fopen($_GET['pname'].".txt", 'w') or die('Could not open playlist!'); unset($plist[$_GET['id']]); $plist = array_values($plist); fwrite($fh,json_encode($plist)); } elseif ($_GET['action'] == 'readp') { if (!file_exists($_GET['pname'].".txt")) { die('Error: No such playlist!'); } $plist = json_decode(file_get_contents($_GET['pname'].".txt"), true); $arr = array("entries" = $plist); $json = json_encode($arr); echo $json; } elseif ($_GET['action'] == 'getps') { $plists = array(); if ($handle = opendir('Playlists')) { while (false !== ($playlist = readdir($handle))) { if ($playlist != "." && $playlist != "..") { array_push($plists, substr($playlist, 0, strripos($playlist, '.')-1)); } } } else { die('Error: Can\'T open playlists!'); } $arr = array("entries"=$plists); $json = json_encode($arr); echo $json; } else { die('Error: No such action!'); } ? It starts in the middle of the array_push(... line. I really can't think of what it is doing. Theres no echos anywhere around it. Any ideas?

  • How to get the selected option value of a drop down box in PHP code

    - by Angeline Aarthi
    I have a dropdown box which lists a set of logos,like flower,butterfly etc. <p class="title1">Logo</p> <select name="logoMenu" class="select" size="7"> <?php foreach($logos as $logo):?> <option id="<?php echo $logo['Subproperty']['id'];?>" value="<?php echo $logo['Subproperty']['values'];?>"><?php echo $logo['Subproperty']['values'];?> </option> <?php endforeach;?> </select> Suppose If I select the logo 'Flower' from the drop down box, I want the flower pic to be displayed in a div.This is the div that I have to display the pictures. <div id="theme_logos" class="float_left spaceleft" style="display:none;"> <?php foreach($defaultLogos as $logo): //if($logo['Subproperty']['values']==clicked option value){?> <img height="50" width="50" src="/FormBuilder/app/webroot/img/themes/<?php echo $logo['Subproperty']['images'];?>" class="float_left user_profile_image user_profile_image" alt="Default50"/> <?php endforeach;?> </div> The problem with this code is that it displaya all the pictures found in the table. Because im My controller code, I give only the property id as that of 'Logo',but do not give which logo. $this->set('defaultLogos',$this->Subproperty->find('all',array('conditions'=>array('Subproperty.property_id'=>1,'Subproperty.values'=>"Flower")))); Here I have hard coded as 'flower' so that I get the flower picture alone.. If I select the logo from the drop down box, how to pass that selected value to the controller code? Or if I get the selected logo name thro' jquery,how to use that value in the if condition inside the for each loop? someone help me out with this.. I'm using CakePHP framework. $("#logoMenu option").click(function(){ selectedLogo=$(this).attr("value"); $('#subproperty_id').val($(this).attr("id")); if(selectedLogo=="Your logo"){ $("#themes_upload").show(); } else{ alert(selectedLogo); $("#themes_upload").hide(); $("#theme_logos").show(); } }); EDIT Now I have tried an ajax post where I pass the selected logo to the same action of the controller. I get the value when I alert the passed value in the success function of the ajax function. I the picture doesn't appear. $("#logoMenu option").click(function(){ selectedLogo=$(this).attr("value"); $('#subproperty_id').val($(this).attr("id")); if(selectedLogo=="Your logo"){ $("#themes_upload").show(); } else{ alert(selectedLogo); $.ajax({ type: "POST", url: "http://localhost/FormBuilder/index.php/themes/themes/", async: false, data: "selectedLogo="+selectedLogo, success: function(msg){ alert( "Data Saved: " + msg); } }); $("#themes_upload").hide(); $("#theme_logos").show(); } }); function themes(){ $this->set('themes',$this->Theme->find('all')); $logo=$this->params['form']['selectedLogo']; echo "logo:".$logo; $this->set('defaultLogos',$this->Subproperty->find('all',array('conditions'=>array('Subproperty.property_id'=>1,'Subproperty.values'=>$logo)))); } But when I trry to display the img in the page,it doesn't appear. Is it because the div show command is after the ajax request?

  • When my UIViewController accesses an NSArray in my AppDelegate from an IBAction it crashes the progr

    - by JasonClark
    I have a couple UIViewControllers that I am trying to access an array inside my AppDelegate. When I use an IBAction UIButton and in that method I access my AppDelegate my program dies silently. Nothing in output or the debugger, it just stops. If I run it several times I can see that it is failing to access the array properly. To investigate this problem I created a very basic app. In my AppDelegate.h I declared and set properties for the array #import <UIKit/UIKit.h> @class MyViewController; @interface MyAppDelegate : NSObject <UIApplicationDelegate> { UIWindow *window; MyViewController *viewController; NSArray *images; } @property (nonatomic, retain) NSArray *images; @property (nonatomic, retain) IBOutlet UIWindow *window; @property (nonatomic, retain) IBOutlet MyViewController *viewController;` In the AppDelegate.m I synthesised and initialized the NSArray (Also made sure the images were added to the Resources folder). @synthesize images; - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { images = [NSArray arrayWithObjects: [[NSBundle mainBundle] pathForResource:@"bamboo_nw" ofType:@"jpg"], ..... nil]; NSLog(@"init images size:%i",[images count]); [window addSubview:viewController.view]; [window makeKeyAndVisible]; return YES; } In my UIViewController.h I added class, imported header file, declared, and set properties for my AppDelegate pointer. #import <UIKit/UIKit.h> #import "MyAppDelegate.h" @class MyAppDelegate; @interface MyViewController : UIViewController { MyAppDelegate *mainDelegate; IBOutlet UIButton mybutton; } @property (nonatomic, retain) MyAppDelegate mainDelegate; @property (nonatomic, retain) UIButton *mybutton; -(IBAction) doSomething;` In my UIViewController.m I synthesize and assign my AppDelegate. I set up an IBAction that will log the same count of the NSArray from the AppDelegate. #import "MyViewController.h" #import "MyAppDelegate.h" @implementation MyViewController @synthesize mybutton; - (void)viewDidLoad { mainDelegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate]; NSLog(@"vdl images size:%i",[mainDelegate.images count]); [super viewDidLoad]; } -(IBAction) doSomething { NSLog(@"ds images size:%i",[mainDelegate.images count]); } I print the size of the NSArray in the AppDelegate when I create it, in the ViewController when I first assign my AppDelegate pointer, and then as a result of my IBAction. I find that everytime I hit the button the program dies. On the third time I hit the button, I saw that it ran my IBAction but printed my array size as 1 instead of 8. Am I missing something? Also, why don't I get stack traces or anything, the debugger just dies silently? Thanks in advance for any help! Debugger Console output for 3 runs: [Session started at 2010-05-10 06:21:32 -0700.] 2010-05-10 06:21:44.865 My[59695:207] init images size:8 2010-05-10 06:21:47.246 My[59695:207] vdl images size:8 [Session started at 2010-05-10 06:22:15 -0700.] 2010-05-10 06:22:18.920 My[59704:207] init images size:8 2010-05-10 06:22:19.043 My[59704:207] vdl images size:8 [Session started at 2010-05-10 06:22:23 -0700.] 2010-05-10 06:22:25.966 My[59707:207] init images size:8 2010-05-10 06:22:26.017 My[59707:207] vdl images size:8 2010-05-10 06:22:27.814 My[59707:207] ds images size:1

  • Yii, Generate unquie ids one each tr element of CGridView

    - by Snow_Mac
    I have a CDbActiveRecord setup and I have a instance of the CGridView class setup as a widget. Basically my end game is I need a table, but each row to contain the primary key of the row associated with the Active Record. Such as: <tr id="123"> <td> Column value 1 </td> <td> Col 2 </td> <td> Col 3 </td> </tr> That's the specific of the row that I'm looking for. Here's the code I've got so far to produce a table. (The json variable is set because this is inside a controller and the widget is returned as json.) // get the content id for the version list $contentID_v = Yii::app()->request->getParam("id"); // setup the criteria to fetch related items $versionCdbCriteria = new CDbCriteria; $versionCdbCriteria->compare("contentID",$contentID_v); // setting up the active data provider for the version $vActiveDP = new CActiveDataProvider("FactsheetcontentVersion", array( "criteria" => $versionCdbCriteria, 'pagination' => array('PageSize' => $this->paginationSize), 'keyAttribute'=>'vID', )); $json_data .= $this->widget('zii.widgets.grid.CGridView', array( 'dataProvider' => $vActiveDP, 'columns' => array( 'title', 'created', 'createdBy' ), 'showTableOnEmpty' => 'false', ),true); This is what it produces for my active record. <div class="grid-view" id="yw0"> <div class="summary">Displaying 1-1 of 1 result(s).</div> <table class="items"><thead> <tr><th id="yw0_c0">Factsheettitle</th> <th id="yw0_c1"><a href="jq/work/admin/index.php?r=factsheetManager/Editor &amp;id=25601&amp;getV=true&amp;_=1341694154760&amp;FactsheetcontentVersion_sort=created">Created</a> </th> <th id="yw0_c2"><a href="jq/work/admin/index.php?r=factsheetManager/ Editor&amp;id=25601&amp;getV=true&amp;_=1341694154760&amp;FactsheetcontentVersion_sort=createdBy">Created By</a> </th> </tr></thead> <tbody><tr class="odd"><td>Distribution</td><td>0000-00-00 00:00:00</td><td>NULL</td></tr></tbody> </table> <div title="jq/work/admin/index.php?r=factsheetManager/Editor&amp;id=12&amp;id=25601&amp;getV=true&amp;_=1341694154760" style="display:none" class="keys"><span>8</span></div> </div>

  • Parallel processing via multithreading in Java

    - by Robz
    There are certain algorithms whose running time can decrease significantly when one divides up a task and gets each part done in parallel. One of these algorithms is merge sort, where a list is divided into infinitesimally smaller parts and then recombined in a sorted order. I decided to do an experiment to test whether or not I could I increase the speed of this sort by using multiple threads. I am running the following functions in Java on a Quad-Core Dell with Windows Vista. One function (the control case) is simply recursive: // x is an array of N elements in random order public int[] mergeSort(int[] x) { if (x.length == 1) return x; // Dividing the array in half int[] a = new int[x.length/2]; int[] b = new int[x.length/2+((x.length%2 == 1)?1:0)]; for(int i = 0; i < x.length/2; i++) a[i] = x[i]; for(int i = 0; i < x.length/2+((x.length%2 == 1)?1:0); i++) b[i] = x[i+x.length/2]; // Sending them off to continue being divided mergeSort(a); mergeSort(b); // Recombining the two arrays int ia = 0, ib = 0, i = 0; while(ia != a.length || ib != b.length) { if (ia == a.length) { x[i] = b[ib]; ib++; } else if (ib == b.length) { x[i] = a[ia]; ia++; } else if (a[ia] < b[ib]) { x[i] = a[ia]; ia++; } else { x[i] = b[ib]; ib++; } i++; } return x; } The other is in the 'run' function of a class that extends thread, and recursively creates two new threads each time it is called: public class Merger extends Thread { int[] x; boolean finished; public Merger(int[] x) { this.x = x; } public void run() { if (x.length == 1) { finished = true; return; } // Divide the array in half int[] a = new int[x.length/2]; int[] b = new int[x.length/2+((x.length%2 == 1)?1:0)]; for(int i = 0; i < x.length/2; i++) a[i] = x[i]; for(int i = 0; i < x.length/2+((x.length%2 == 1)?1:0); i++) b[i] = x[i+x.length/2]; // Begin two threads to continue to divide the array Merger ma = new Merger(a); ma.run(); Merger mb = new Merger(b); mb.run(); // Wait for the two other threads to finish while(!ma.finished || !mb.finished) ; // Recombine the two arrays int ia = 0, ib = 0, i = 0; while(ia != a.length || ib != b.length) { if (ia == a.length) { x[i] = b[ib]; ib++; } else if (ib == b.length) { x[i] = a[ia]; ia++; } else if (a[ia] < b[ib]) { x[i] = a[ia]; ia++; } else { x[i] = b[ib]; ib++; } i++; } finished = true; } } It turns out that function that does not use multithreading actually runs faster. Why? Does the operating system and the java virtual machine not "communicate" effectively enough to place the different threads on different cores? Or am I missing something obvious?

  • JSON Paring - How to show second Level ListView

    - by Sophie
    I am parsing JSON data into ListView, and successfully parsed first level of JSON in MainActivity.java, where i am showing list of Main Locations, like: Inner Locations Outer Locations Now i want whenever i do tap on Inner Locations then in SecondActivity it should show Delhi and NCR in a List, same goes for Outer Locations as well, in this case whenever user do tap need to show USA JSON look like: { "all": [ { "title": "Inner Locations", "maps": [ { "title": "Delhi", "markers": [ { "name": "Connaught Place", "latitude": 28.632777800000000000, "longitude": 77.219722199999980000 }, { "name": "Lajpat Nagar", "latitude": 28.565617900000000000, "longitude": 77.243389100000060000 } ] }, { "title": "NCR", "markers": [ { "name": "Gurgaon", "latitude": 28.440658300000000000, "longitude": 76.987347699999990000 }, { "name": "Noida", "latitude": 28.570000000000000000, "longitude": 77.319999999999940000 } ] } ] }, { "title": "Outer Locations", "maps": [ { "title": "United States", "markers": [ { "name": "Virgin Islands", "latitude": 18.335765000000000000, "longitude": -64.896335000000020000 }, { "name": "Vegas", "latitude": 36.114646000000000000, "longitude": -115.172816000000010000 } ] } ] } ] } Note: But whenever i do tap on any of the ListItem in first activity, not getting any list in SecondActivity, why ?

  • data not reloading into tableview from core data on minor update

    - by Martin KS
    I've got a basic photo album application, on the first view a list of albums is displayed with a subtitle showing how many images are in each album. I've got everything working to add albums, and add images to albums. The problem is that the image count lines are accurate whenever the app loads, but I can't get them to update during execution. The following viewdidload correctly populates all lines of the tableview when the app loads: - (void)viewDidLoad { [super viewDidLoad]; // Set the title. self.title = @"Photo albums"; // Configure the add and edit buttons. self.navigationItem.leftBarButtonItem = self.editButtonItem; addButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAdd target:self action:@selector(addAlbum)]; addButton.enabled = YES; self.navigationItem.rightBarButtonItem = addButton; /* Fetch existing albums. Create a fetch request; find the Album entity and assign it to the request; add a sort descriptor; then execute the fetch. */ NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Album" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; // Order the albums by name. NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"albumName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; // Execute the fetch -- create a mutable copy of the result. NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults == nil) { // Handle the error. } LocationsAppDelegate *mainDelegate = (LocationsAppDelegate *)[[UIApplication sharedApplication] delegate]; // Set master albums array to the mutable array, then clean up. [mainDelegate setAlbumsArray:mutableFetchResults]; [mutableFetchResults release]; [request release]; } But when I run similar code inside viewdidappear, nothing happens: { /* Fetch existing albums. Create a fetch request; find the Album entity and assign it to the request; add a sort descriptor; then execute the fetch. */ NSFetchRequest *request = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Album" inManagedObjectContext:managedObjectContext]; [request setEntity:entity]; // Order the albums by creation date, most recent first. NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"albumName" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [request setSortDescriptors:sortDescriptors]; [sortDescriptor release]; [sortDescriptors release]; // Execute the fetch -- create a mutable copy of the result. NSError *error = nil; NSMutableArray *mutableFetchResults = [[managedObjectContext executeFetchRequest:request error:&error] mutableCopy]; if (mutableFetchResults == nil) { // Handle the error. } LocationsAppDelegate *mainDelegate = (LocationsAppDelegate *)[[UIApplication sharedApplication] delegate]; // Set master albums array to the mutable array, then clean up. [mainDelegate setAlbumsArray:mutableFetchResults]; [self.tableView reloadData]; [mutableFetchResults release]; [request release]; } Apologies if I've missed the answer to this question elsewhere, but what am I missing?

  • extensible database design: automatic ALTER TABLE or serialize() field BLOB ?

    - by mario
    I want an adaptable database scheme. But still use a simple table data gateway in my application, where I just pass an $data[] array for storing. The basic columns are settled in the initial table scheme. There will however arise a couple of meta fields later (ca 10-20). I want some flexibility there and not adapt the database manually each time, or -worse- change the application logic just because of new fields. So now there are two options which seem workable yet not overkill. But I'm not sure about the scalability or database drawbacks. (1) Automatic ALTER TABLE. Whenever the $data array is to be saved, the keys are compared against the current database columns. New columns get defined before the $data is INSERTed into the table. Actually seems simple enough in test code: function save($data, $table="forum") { // columns if ($new_fields = array_diff(array_keys($data), known_fields($table))) { extend_schema($table, $new_fields, $data); } // save $columns = implode("`, `", array_keys($data)); $qm = str_repeat(",?", count(array_keys($data)) - 1); echo ("INSERT INTO `$table` (`$columns`) VALUES (?$qm);"); function known_fields($table) { return unserialize(@file_get_contents("db:$table")) ?: array("id"); function extend_schema($table, $new_fields, $data) { foreach ($new_fields as $field) { echo("ALTER TABLE `$table` ADD COLUMN `$field` VARCHAR;"); Since it is mostly meta information fields, adding them just as VARCHAR seems sufficient. Nobody will query by them anyway. So the database is really just used as storage here. However, while I might want to add a lot of new $data fields on the go, they will not always be populated. (2) serialize() fields into BLOB. Any new/extraneous meta fields could be opaque to the database. Simply sorting out the virtual fields from the real database columns is simple. And the meta fields can just be serialize()d into a blob/text field then: function ext_save($data, $table="forum") { $db_fields = array("id", "content", "flags", "ext"); // disjoin foreach (array_diff(array_keys($data),$db_fields) as $key) { $data["ext"][$key] = $data[$key]; unset($data[$key]); } $data["ext"] = serialize($data["ext"]); Unserializing and unpacking this 'ext' column on read queries is a minor overhead. The advantage is that there won't be any sparsely filled columns in the database, so I guess it's compacter and faster than the AUTO ALTER TABLE approach. Of course, this method prevents ever using one of the new fields in a WHERE or GROUP BY clause. But I think none of the possible meta fields (user_agent, author_ip, author_img, votes, hits, last_modified, ..) would/should ever be used there anyway. So I currently prefer the 'ext' blob approach, even if it's a one-way ticket. How are such columns called usually? (looking for examples/doc) Would you use XML serialization for (very theoretical) in-database queries? The adapting table scheme seems a "cleaner" interface, even if most columns might remain empty then. How does that impact speed? How many such sparse VARCHAR fields can MySQL/innodb stomach? But most importantly: Is there any standard implementation for this? A pseudo ORM with automatic ALTER TABLE tricks? Storing a simple column list seems workable, but something like pdo::getColumnMeta would be more robust.
