  • Detecting syllables in a word

    - by user50705
    I need to find a fairly efficient way to detect syllables in a word. E.g., invisible - in-vi-sib-le There are some syllabification rules that could be used: V CV VC CVC CCV CCCV CVCC *where V is a vowel and C is a consonant. e.g., pronunciation (5 Pro-nun-ci-a-tion; CV-CVC-CV-V-CVC) I've tried few methods, among which were using regex (which helps only if you want to count syllables) or hard coded rule definition (a brute force approach which proves to be very inefficient) and finally using a finite state automata (which did not result with anything useful). The purpose of my application is to create a dictionary of all syllables in a given language. This dictionary will later be used for spell checking applications (using Bayesian classifiers) and text to speech synthesis. I would appreciate if one could give me tips on an alternate way to solve this problem besides my previous approaches. I work in Java, but any tip in C/C++, C#, Python, Perl... would work for me.

  • How to actually use ZeroClipboard in jQuery?

    - by Martti Laine
    Hello I just can't get this thing. How is ZeroClipboard supposed to work? Why does it need to move the flash-element over the copied text? I've read this thing: http://code.google.com/p/zeroclipboard/wiki/Instructions Can someone provide me a short snippet, which makes it possible to copy a text in variable to users clipboard, when user clicks a link. Is this even possible? I don't care, if it doesn't work on all browsers (IE6 for example). I'm using jQuery. Martti Laine

  • What could cause a button on a UIActionSheet to "miss" on touches?

    - by Alex Gosselin
    I have a UIActionSheet as follows: UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:[NSString stringWithFormat: @"Cancel New %@? Changes will be lost.", [creator propertyName]] delegate:self cancelButtonTitle:@"Stay Here" destructiveButtonTitle:@"Discard and Close" otherButtonTitles:@"Save and Close", nil]; [sheet showInView:self.view]; [sheet release]; It creates the action sheet, The buttons display, the Destructive button is on top, cancel button is on the bottom, other button (save and close) shows up in the middle, the top two buttons, (destructive and other) work fine, but the bottom button has a gap, so it is farther down than the other buttons. For some reason though, in order to press the button I need to touch where it would be if there was no gap. Touching the actual button doesn't work. Sorry if this isn't super clear, has anyone encountered something like this? I don't like to whip out the "I found a bug" card too fast, maybe I'm doing something wrong here.

  • What is the proper way to create a recursive entity in the Entity Framework?

    - by Orion Adrian
    I'm currently using VS 2010 RC, and I'm trying to create a model that contains a recursive self-referencing entity. Currently when I import the entity from the model I get an error indicating that the parent property cannot be part of the association because it's set to 'Computed' or 'Identity', though I'm not sure why it does it that way. I've been hand-editing the file to get around that error, but then the model simply doesn't work. What is the proper way to get recursive entities to work in the Entity Framework. CREATE TABLE [dbo].[Appointments]( [AppointmentId] [int] IDENTITY(1,1) NOT NULL, [Description] [nvarchar](1024) NULL, [Start] [datetime] NOT NULL, [End] [datetime] NOT NULL, [Username] [varchar](50) NOT NULL, [RecurrenceRule] [nvarchar](1024) NULL, [RecurrenceState] [varchar](20) NULL, [RecurrenceParentId] [int] NULL, [Annotations] [nvarchar](50) NULL, [Application] [nvarchar](100) NOT NULL, CONSTRAINT [PK_Appointments] PRIMARY KEY CLUSTERED ( [AppointmentId] ASC ) ) GO ALTER TABLE [dbo].[Appointments] WITH CHECK ADD CONSTRAINT [FK_Appointments_ParentAppointments] FOREIGN KEY([RecurrenceParentId]) REFERENCES [dbo].[Appointments] ([AppointmentId]) GO ALTER TABLE [dbo].[Appointments] CHECK CONSTRAINT [FK_Appointments_ParentAppointments] GO

  • Use API or SQL to detect new Support Tickets?

    - by David Powers
    I currently work for a company that uses Kayako for their support system. They sell an extra program called Insta Alert that plays a sound when a new ticket is submitted. I use WHMCS for my own company, and would like to develop something to work with it that does the same thing. Here is the WHMCS API... http://wiki.whmcs.com/API:Functions I am wondering if it would make more sense from a remote C++ application to use the API or just check the MySQL database for new tickets? This is not really something im overly familiar with (I usually make mods) but it doesn't seem overly difficult. I just want some assistance in choosing the best approach.

  • Image Viewer application, Image processing with Dispaly Data.

    - by Harsha
    Hello All, I am working on Image Viewer application and planning to build in WPF. My Image size are usually larger than 3000x3500. After searching for week, I got sample code from MSDN. But it is written in ATL COM. So I am planning to work and build the Image viewer as follows: After reading the Image I will scale down to my viewer size, viwer is around 1000x1000. Lets call this Image Data as Display Data. Once displaying this data, I will work only this Display data. For all Image processing operation, I will use this display data and when user choose to save the image, I will apply all the operation to original Image data. My question is, Is is ok to use Display data for showing and initial image processing operations.

  • Import and Export for CSV are both broken in Mathematica

    - by dreeves
    Consider the following 2 by 2 array: x = {{"a b c", "1,2,3"}, {"i \"comma-heart\" you", "i \",heart\" u, too"}} If we Export that to CSV and then Import it again we don't get the same thing back: Import[Export["tmp.csv", d]] Looking at tmp.csv it's clear that the Export didn't work, since the quotes are not escaped properly. According to the RFC which I presume is summarized correctly on Wikipedia's entry on CSV, the right way to export the above array is as follows: a b c, "1,2,3" "i ""heart"" you", "i "",heart"" u, too" Importing the above does not yield the original array either. So Import is broken as well. I've reported these bugs to [email protected] but I'm wondering if others have workarounds in the meantime. One workaround is to just use TSV instead of CSV. I tested the above with TSV and it seems to work (even with tabs embedded in the entries of the array).

  • Easiest way to find the correct kademlia bucket

    - by Martin
    In the Kademlia protocol node IDs are 160 bit numbers. Nodes are stored in buckets, bucket 0 stores all the nodes which have the same ID as this node except for the very last bit, bucket 1 stores all the nodes which have the same ID as this node except for the last 2 bits, and so on for all 160 buckets. What's the fastest way to find which bucket I should put a new node into? I have my buckets simply stored in an array, and need a method like so: Bucket[] buckets; //array with 160 items public Bucket GetBucket(Int160 myId, Int160 otherId) { //some stuff goes here } The obvious approach is to work down from the most significant bit, comparing bit by bit until I find a difference, I'm hoping there is a better approach based around clever bit twiddling. Practical note: My Int160 is stored in a byte array with 20 items, solutions which work well with that kind of structure will be preferred.

  • Sort and display directory list alphabetically using opendir() in php

    - by felixthehat
    Hi there, php noob here - I've cobbled together this script to display a list of images from a folder with opendir, but I can't work out how (or where) to sort the array alphabetically <?php // opens images folder if ($handle = opendir('Images')) { while (false !== ($file = readdir($handle))) { // strips files extensions $crap = array(".jpg", ".jpeg", ".JPG", ".JPEG", ".png", ".PNG", ".gif", ".GIF", ".bmp", ".BMP", "_", "-"); $newstring = str_replace($crap, " ", $file ); //asort($file, SORT_NUMERIC); - doesnt work :( // hides folders, writes out ul of images and thumbnails from two folders if ($file != "." && $file != ".." && $file != "index.php" && $file != "Thumbnails") { echo "<li><a href=\"Images/$file\" class=\"thickbox\" rel=\"gallery\" title=\"$newstring\"><img src=\"Images/Thumbnails/$file\" alt=\"$newstring\" width=\"300\" </a></li>\n";} } closedir($handle); } ?> Any advice or pointers would be much appreciated!

  • ImageCaptureCore documentation

    - by Marc Rochkind
    There are a few overviews in the OS X 10.6 docs that I access via XCode, and a bunch of examples, but the actual reference docs seem to be absent. I was able to figure things out by reading the inline comments in the header files (e.g., ICCameraDevice.h), which looks like the source for the XCode docs. Is there a way to install these docs? The biggest problem with the overview writeups and the examples is that they assume you have a GUI. The whole point of ImageCaptureCore, vs. ImageKit, as I understand it is that you don't have a GUI, or want to have your own (my case). Anyone else have a good time figuring out how these APIs work? Way too much work! --Marc

  • load a pickle file from a zipfile

    - by eric.frederich
    For some reason I cannot get cPickle.load to work on the file-type object returned by ZipFile.open(). If I call read() on the file-type object returned by ZipFile.open() I can use cPickle.loads though. Example .... import zipfile import cPickle # the data we want to store some_data = {1: 'one', 2: 'two', 3: 'three'} # # create a zipped pickle file # zf = zipfile.ZipFile('zipped_pickle.zip', 'w', zipfile.ZIP_DEFLATED) zf.writestr('data.pkl', cPickle.dumps(some_data)) zf.close() # # cPickle.loads works # zf = zipfile.ZipFile('zipped_pickle.zip', 'r') sd1 = cPickle.loads(zf.open('data.pkl').read()) zf.close() # # cPickle.load doesn't work # zf = zipfile.ZipFile('zipped_pickle.zip', 'r') sd2 = cPickle.load(zf.open('data.pkl')) zf.close() Note: I don't want to zip just the pickle file but many files of other types. This is just an example.

  • PredicateBuilder "And" Method not working

    - by mikemurf22
    I have downloaded the predicate builder and am having a difficult time getting it to work with the entity framework. Here is my code: v_OrderDetail is the entity var context = new OrdersEntities(); Expression<Func<v_OrderDetail,bool>> whereClause = w => true; var predicate = PredicateBuilder.True<v_OrderDetail>(); predicate.And(w => w.Status == "Work"); var results = context.v_OrderDetail.AsExpandable().Where(predicate); When I look at the results I get back every order. The And predicate doesn't seem to take. When I look at the predicate.parameters.count it only shows 1. I'm not sure, but I would expect it to show 2 after I add the second one. Any help is greatly appreciated.

  • latex: curly braces outside math

    - by basweber
    Hi, I am producing some latex beamer slides (but I think it is not a beamer specific question per se). I have the following: \begin{itemize} \item Issue1 \item Issue2 \item Issue3 \end{itemize} now I want to have a right curly brace (i.e. '}') behind the items spreading over issue1 and issue2. And of course I want to write something behind that curly brace I a perfect world I would write something like: \begin{itemize} \left . \item Issue1 \item Issue2 \right \\} One and Two are cool \item Issue3 \end{itemize} This does not work because I am not in a math environment and I can not put the whole snippet inside a math environment because itemize would not work in that case. Is their a clean solution or a hack to produce my desired result? Regards, Bastian.

  • How to export scrubyt extractor?

    - by robintw
    I've written a scrubyt extractor based on the 'learning' technique - that is, specifying the current text on the page and getting it to work out the XPath expressions itself. However, I now want to export the extractor so that it can be used even when the page has changed. The documentation for scrubyt seems to be all over the place now, but from what I can find I should be able to put the line extractor.export(__FILE__) and it should work. It doesn't - I just get an error saying that there is the wrong number of arguments for export, it should have 0. I've tried it without any arguments and it still fails. I would ask on the scrubyt forum, but it seems like no-one's been there for ages! Any ideas what to do here?

  • Logging from symfony's model layer

    - by naag
    I'm currently working on a project with symfony 1.4 and Doctrine 1.2. I'm looking for a proper way to do logging from the model layer. In some model classes I use the record hook postSave() to create a ZIP file using exec() (since PHP zip doesn't provide for storage method 'Stored'). To be sure that everythings works fine I check the return code and log an error if something goes wrong. My first naive approach was to do it like this: if ($returnCode != 0) { sfContext::getInstance()->getLogger()->debug(...); } As you know, this doesn't work so well because sfContext belongs to the controller layer and shouldn't be used from the model layer. My next try was to use the model's constructor to pass in an sfLogger instance, but this doesn't work due to Doctrine 1.2 reserving the constructor for internal use (Doctrine 1.2 Documentation). I'm looking forward for your suggestions!

  • Write wave files to memory in Java

    - by Cliff
    I'm trying to figure out why my servlet code creates wave files with improper headers. I use: AudioSystem.write( new AudioInputStream( new ByteArrayInputStream(memoryBytes), new AudioFormat(22000, 16, 1, true,false), memoryBytes.length ), AudioFileFormat.Type.WAVE, servletOutputStream ); taking a byte array from memory containing raw PCM samples and a servlet output stream that gets returned to the client. In the result I get a normal wave file but with zeros in the chunk size fields. Is the API broken? I would think that the size could be filled in using the size passed in the audio input stream. But now, after typing this out I'm thinking its not making this info available to the outer write() method on AudioSystem. It seems like the AudioSystem.write call needs a size parameter unless it is able to pull the size from the stream... which wouldn't work with an arbitrary sized stream. Does anyone know how to make this example work?

  • merging UIImagePickerController image with cameraOverlayView

    - by GameDev
    Im really in the need for some help and advice. Spent the last week on this and have now just become frustrated as i cant get it to work! Basically, im trying to merge two images into one image to display/save. First the user picks an image from album, it goes to edit image screen where user can move and scale the image. On this screen is an overlay image (320x480) for the person to align there eyes in. Once aligned I want to save this image (edited and overlay) into one and pass the image onto my next screen. It works fine when the image is filling the edit/crop box, but when the image is widescreen with top and bottom not filling the box, then when i save the image the coords of the overlay dont get saved correctly! Heres my code, ive tried various ways of doing this but have failed at every attempt :( - (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Access the cropped image from info dictionary UIImage *image = [info objectForKey:@"UIImagePickerControllerEditedImage"]; // Combine image with overlay before saving!! image = [self addOverlayToImage:image]; overlayGraphicView.image = nil; // Take the picture image to the post picture view controller postPictureView = [[PostPictureViewController alloc] init:image Company:companyName withLink:buyButtonLink]; [picker pushViewController:postPictureView animated:YES]; [picker release],picker = nil; } The problem is that the image picked (originalImage) could be of any height, my overlayImage is however always 320x480, its almost all transparent with just two eye images in center which i want to save over the original images eyes! - (UIImage*) addOverlayToImage:(UIImage*)originalImage { CGRect cgRect =[[UIScreen mainScreen] bounds]; CGSize size = cgRect.size; UIGraphicsBeginImageContext(size); [originalImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage* overlayImage = [UIImage imageNamed:overlayGraphicName]; [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage *finalImage = UIGraphicsGetImageFromCurrentImageContext(); [finalImage retain]; UIGraphicsEndImageContext(); return finalImage; } I wish there was just an easy way to take a screenshot of whatever is in the edit crop box :( Please if someone could help me with this ASAP as I need to finish this in 1-2 days time! Thank you. EDIT:- I should also mention that with this I get the correct center of the screen and placement of the overlay on my next screen: [(UIImage *)overlayImage drawInRect:CGRectMake(0, 0, size.width, size.height)]; However, I am unable to work out the correct position of the main image especially as the height is different for every image if not fullscreen! I tried this to center it into the correct position but it doesnt work: [originalImage drawInRect:CGRectMake(0,(size.height/2 - originalImage.size.height/2), originalImage.size.width, originalImage.size.height)];

  • Windows Azure worker roles: One big job or many small jobs?

    - by Ryan Elkins
    Is there any inherent advantage when using multiple workers to process pieces of procedural code versus processing the entire load? In other words, if my workflow looks like this: Get work from queue0 and do A Store result from A in queue1 Get result from queue 1 and do B Store result from B in queue2 Get result from queue2 and do C Is there an inherent advantage to using 3 workers who each do the entire process themselves versus 3 workers that each do a part of the work (Worker 1 does 1 & 2, worker 2 does 3 & 4, worker 3 does 5). If we only care about working being done (finished with step 5) it would seem that it scales the same way (once you're using at least 3 workers). Maybe the big job is better because workers with that setup have less bottleneck issues?

  • asp:Menu Not working on webhost

    - by Brian
    I'm using Visual Studio Web Express 2008 to develop an ASP.Net website. I have a master page that every page inherits from and on that master page I have the asp:menu control. On my local machine the menu control works just fine. The javascript is emitted and the links work as well. However, when I upload it to my webhost service provider, the javascript is not emitted and my links do not work. I'm getting a feeling that my service provider really doesn't know much about .Net as they suggested that I make sure that I upload the .js files which isn't necessary. Does anyone have any suggestions that I can give them? They're asking me what requirements are needed. It seems to me that something is not setup on their server properly but according to them, they have .Net 3.5 SP1 installed.

  • HttpClient response handler always returns closed stream

    - by Alex Ciminian
    I'm new to Java development so please bear with me. Also, I hope I'm not the champion of tl;dr :). I'm using HttpClient to make requests over Http (duh!) and I'd gotten it to work for a simple servlet that receives an URL as a query string parameter. I realized that my code could use some refactoring, so I decided to make my own HttpResponseHandler, to clean up the code, make it reusable and improve exception handling. I currently have something like this: public class HttpResponseHandler implements ResponseHandler<InputStream>{ public InputStream handleResponse(HttpResponse response) throws ClientProtocolException, IOException { int statusCode = response.getStatusLine().getStatusCode(); InputStream in = null; if (statusCode != HttpStatus.SC_OK) { throw new HttpResponseException(statusCode, null); } else { HttpEntity entity = response.getEntity(); if (entity != null) { in = entity.getContent(); // This works // for (int i;(i = in.read()) >= 0;) System.out.print((char)i); } } return in; } } And in the method where I make the actual request: HttpClient httpclient = new DefaultHttpClient(); HttpGet httpget = new HttpGet(target); ResponseHandler<InputStream> httpResponseHandler = new HttpResponseHandler(); try { InputStream in = httpclient.execute(httpget, httpResponseHandler); // This doesn't work // for (int i;(i = in.read()) >= 0;) System.out.print((char)i); return in; } catch (HttpResponseException e) { throw new HttpResponseException(e.getStatusCode(), null); } The problem is that the input stream returned from the handler is closed. I don't have any idea why, but I've checked it with the prints in my code (and no, I haven't used them both at the same time :). While the first print works, the other one gives a closed stream error. I need InputStreams, because all my other methods expect an InputStream and not a String. Also, I want to be able to retrieve images (or maybe other types of files), not just text files. I can work around this pretty easily by giving up on the response handler (I have a working implementation that doesn't use it), but I'm pretty curious about the following: Why does it do what it does? How do I open the stream, if something closes it? What's the right way to do this, anyway :)? I've checked the docs and I couldn't find anything useful regarding this issue. To save you a bit of Googling, here's the Javadoc and here's the HttpClient tutorial (Section 1.1.8 - Response handlers). Thanks, Alex

  • XML databinding to TreeView (or Tab control), bind attribute based on different attribute

    - by Number8
    Hello, I have some xml: <Test> <thing location="home" status="good"/> <thing location=work" status="bad"/> <thing location="mountains" status="good"/> </Test> The leaves on the TreeView are the values of the status attribute; the nodes will be the value of the location attribute. +--bad ¦.....+--work +--good .......+--home .......+--mountains Currently, I populate the TreeView (or Tab control) manually, iterating through the xml, adding the nodes to the appropriate leaf. Can this be done via databinding? I'm guessing a Converter will be involved... Thanks for any advice.

  • Is this an example of polymorphism?

    - by computer-science-student
    I'm working on a homework assignment (a project), for which one criterion is that I must make use of polymorphism in a way which noticeably improves the overall quality or functionality of my code. I made a Hash Table which looks like this: public class HashTable<E extends Hashable>{ ... } where Hashable is an interface I made that has a hash() function. I know that using generics this way improves the quality of my code, since now HashTable can work with pretty much any type I want (instead of just ints or Strings for example). But I'm not sure if it demonstrates polymorphism. I think it does, because E can be any type that implements Hashable. In other words HashTable is a class which can work with (practically) any type. But I'm not quite sure - is that polymorphism? Perhaps can I get some clarification as to what exactly polymorphism is? Thanks in advance!

  • Recommendation for serial communications in Access 2007

    - by bglenn
    I need to communicate with a bar code scanner connected over a serial port in Microsoft Access. In older versions of Access I was able to use a wrapper around MSCOMM32.ocx that no longer seems to work. I can't use wedge communication because I need to use ACK/NACK which is only supported through the RS232 interface and I need to send messages to the scanner, which is also only supported through the RS232 interface. Are there any controls in widespread use that support serial communication in Access 2007? EDIT: In case anyone comes across this, the newest version of MSCOMM32.ocx (I believe dated 3/09) still works fine as of this writing. It is older versions of MSCOMM32.ocx that do not work.
