• Quickest and easiest way to implement speech to text conversion for a small speech subset.

  - by sgtpeppers

  Hi, I want to implement a system that receives speech through a microphone on my Mac OS x. I know arbitrary speech recognition is close to impossible without training the system so I'm willing to restrict it to 10 simple sentences. It must recognize with a high degree of accuracy which of these 10 sentences are being spoken, generate the text and add an entry to a remote MySQL database. With these being the architecture of the system I want to implement, could anyone give me an overview of what would be the best way to go about implementing this system? I'm looking for ideas like open source libraries to minimize the coding as this is just a prototype application for a demonstration. Basically I'm looking for a quick and easy solution. Thanks!

• Do you have any tips for comments code to keep them in step with the code?

  - by Rob Wells

  G'day, I've read both of Steve McConnell's excellent Code Complete books "Code Complete" and "Code Complete 2" and was wondering if people have any other suggestions for commenting code. My commenting mantra could be summed up by the basic idea of expressing "what the code below cannot say". While enjoying this interesting blog post by Jeff about commenting I was still left wondering "When coding, when do you feel a comment is required?" Edit: Oops. Seems to be a duplicate of this question http://stackoverflow.com/questions/121945/how-do-you-like-your-comments so sorry for the noise. Thanks to my, seemingly, SO shadow for pointing it out - wouldn't have thought I was that interesting. Now off to read the original post and see if it is relevant. Edit: I meant to emphasise the best appraoch to ensure that your comments will stay in step with the code. Maybe expressing an intent rather than the mechansim for instance.

• Social Gold API Integration Help Wanted

  - by xotyc

  Hi, Where can I find someone who is experienced in Social Gold API Integration with a private social networking website (as opposed to Facebook or others)? My network in built on the NING.com platform. Hope that's not seen as a negative thing. I need to integrate Social Gold virtual currency but have no knowledge of API coding etc. I understand this will only take less than an hour to do but I need someone who knows what they're doing and who will be 100% ethical in their work. Thanks, RB

• Best practice for making code portable for domains, subdomains or directores

  - by Duopixel

  I recently coded something where it wasn't known if the end code would reside in a subdomain (http://user.domain.com/) or in a subdomain (http://domain.com/user), and I was lost as to the best practice for these unknown scenarios. I could thinks of a couple: Use absolute paths (/css/styles.css) and modrewrite if it ends up being /user Have a settings file and declare a variable with the path (<? php echo $domain . "/css/styles" ?>) Use relative paths (../css/styles.css). What is the best way to handle this?

• Twisted Python getPage

  - by David Dixon II

  I tried to get support on this but I am TOTALLY confused. Here's my code: from twisted.internet import reactor from twisted.web.client import getPage from twisted.web.error import Error from twisted.internet.defer import DeferredList from sys import argv class GrabPage: def __init__(self, page): self.page = page def start(self, *args): if args == (): # We apparently don't need authentication for this d1 = getPage(self.page) else: if len(args) == 2: # We have our login information d1 = getPage(self.page, headers={"Authorization": " ".join(args)}) else: raise Exception('Missing parameters') d1.addCallback(self.pageCallback) dl = DeferredList([d1]) d1.addErrback(self.errorHandler) dl.addCallback(self.listCallback) def errorHandler(self,result): # Bad thingy! pass def pageCallback(self, result): return result def listCallback(self, result): print result a = GrabPage('http://www.google.com') data = a.start() # Not the HTML I wish to get the HTML out which is given to pageCallback when start() is called. This has been a pita for me. Ty! And sorry for my sucky coding.

• VIM: created syntax not showing up?

  - by joxnas

  HI people I recently changed to VIM for coding in C. I'd like to hightlight the operators +-<=& ... etc I searched in google how should i do it, and i found the answer in this website: I was suppose to do something like: syntax match Operadores /[][><()&!|+*={}-]/ hi Operadores guifg=#000000 gui=BOLD Those characters were supposed to appear as black, bold characters. However, that doesn't happen when I open my .C files. However, if I create a newfile, (where there the C syntax doesn't show up), I am able to see the black, bolded operators. How can i correct this situation, and why is this happening (it seams like if my syntax is beeing overwrided by the C syntax). I'm using gvim, and this is my vimrc: colorscheme nicotine set smartindent set number set guifont=Inconsolata\ Medium\ 11 set numberwidth=5 noremap j jzz noremap k kzz Thanks, any help is appreciated. (And dont forget I'm a novice in VIM, and ..sorry for my English)

• Design view disappeared from Interface Builder

  - by skywalker168

  All of a sudden, the visual design window disappeared from my Interface Builder. It is a regular UIView, has some UIImageView, UILabel, and UIButtons on it. When I open IB, I can see the document window (with File's Owner, First Responder and View in it), Library and Inspector, but the visual design window disappeared. Double click on "View" in the document window doesn't do anything. If I go to List mode, I can see all the components on the view, but just can no longer find the visual design window. All other XIB can open just fine, only this XIB lost its design window. First I thought maybe it was hidden somewhere on the screen. Tried all kinds of things, even rebooting the computer, but nothing helped. Can anyone help? Thanks in advance! By the way, I'm running SDK 3.2 Beta 3.

• jquery slider breaks on page refrsh

  - by Nik

  I have a jquery content slider on a site I'm developing. I am having a strange problem that seems to be across all browsers and that is the slider slides the wrong distance if the page is refreshed via the refresh button. To re-create the problem please follow these steps - click this link http://www.aus-media.com/dev/site_BYS/index.html then click on the 'About Bikram Yoga' menu item at the bottom. Click on the 'more' and 'back' tabs on this page and you will notice it works fine. Then refresh the page by clicking the refresh button and try the more and back buttons again. I'm a bit of a javascript newby so I'm lost to why it's doing this. Any help would be great. Thanks Nik

• How to avoid code duplication for one-off methods with a slightly different signature

  - by Sean

  I am wrapping a number of functions from a vender API in C#. Each of the wrapping functions will fit the pattern: public IEnumerator<IValues> GetAggregateValues(string pointID, DateTime startDate, DateTime endDate, TimeSpan period) { // Validate Data // Break up Requesting Time-Span // Make Requests // Read Results (through another method call } 5 of the 6 requests are aggregate data pulls and have the same signature, so it makes sense to put them in one method and pass the aggregate type to avoid duplication of code. The 6th method however follows the exact same pattern with the same result-set, but is not an aggregate, so no time period is passed to the function (changing the signature). Is there an elegant way to handle this kind of situation without coding a one-off function to handle the non-aggregate request?

• Does it make sense to have more than one UDP Datagram socket on standby? Are "simultaneous" packets

  - by Gubatron

  I'm coding a networking application on Android. I'm thinking of having a single UDP port and Datagram socket that receives all the datagrams that are sent to it and then have different processing queues for these messages. I'm doubting if I should have a second or third UDP socket on standby. Some messages will be very short (100bytes or so), but others will have to transfer files. My concern is, will the Android kernel drop the small messages if it's too busy handling the bigger ones? Update "The latter function calls sock_queue_rcv_skb() (in sock.h), which queues the UDP packet on the socket's receive buffer. If no more space is left on the buffer, the packet is discarded. Filtering also is performed by this function, which calls sk_filter() just like TCP did. Finally, data_ready() is called, and UDP packet reception is completed."

• ASP.NET MVC: Is it "wrong" to use HTTP 500 via an AJAX request to return invalid form content?

  - by Daniel Schaffer

  Here's the situation: I've got two partial views. One has a form. What needs to happen is when the form is posted via an AJAX request, if the operation succeeds, the area with the second partial is repopulated with the content. However, if the posted data was invalid, the original partial is repopulated with an error message. I'm using jQuery and the ajaxForm plugin to handle the form posts and responses. Would it be "wrong"/bad coding/wtf-worthy to conditionally use $.html() to replace the content in one area when it's a 200, and a different area if it's a 500? To me, this idea smells, but I'm not sure how else to accomplish the goal.

• Perl references not returning correct values

  - by martincarlin87

  Hi, this is my first time asking a question here so apologies if I am not following any conventions correctly. I encountered a bug in some Perl code that basically lost any parameters in the URL after the first name-value pair and the solution was to use the URI::Escape function on the URL. After this change I decided to move code that does this to a Perl module (Utils.pm) so that any future changes only need to be made once in this file, rather than have to update every file that uses it. The problem I seem to have is that the user, passwd and priv variables don't seem to return the correct values - the system still allows you to sign in but it can't identify your name or the privileges that you have. Below is a link to a pastebin of the code I believe to be relevant to the problem. I believe it is to do with the references but any changes I make just break the page! If anyone has any ideas I would greatly appreciate the help. http://pastebin.com/tqGfGutW

• XCode 3.2 does not mark unit test assert failures in the editor

  - by Cliff

  I've been off in Java land for about a month or so and now, upon returning to XCode I feel lost. I've upgraded 1st to 3.1.2 then recently to 3.2 and also got a new Mac with Snow Leopard so I'm not exactly sure when the problem surfaced. I just know that I used to get little red bubbles in my unit test next to the failing asserts and that no longer seems to happen. Is there a way to restore this? I've been trying to use Apple's own SenTesting framework instead of GoogleTools for mac like I used to. Should I revert to Google Tools? Does anyone have an answer?

• Preserve images in Excel headers using Apache POI

  - by ddm

  I am trying to generate Excel reports using Apache POI 3.6 (latest). Since POI has limited support for header and footer generation (text only), I decided to start from a blank excel file with the header already prepared and fill the Excel cells using POI (cf. question 714172). Unfortunately, when opening the workbook with POI and writing it immediately to disk (without any cell manpulation), the header seems to be lost. Here is the code I used to test this behavior: public final class ExcelWorkbookCreator { public static void main(String[] args) { FileOutputStream outputStream = null; try { outputStream = new FileOutputStream(new File("dump.xls")); InputStream inputStream = ExcelWorkbookCreator.class.getResourceAsStream("report_template.xls"); HSSFWorkbook workbook = new HSSFWorkbook(inputStream, true); workbook.write(outputStream); } catch (Exception exception) { throw new RuntimeException(exception); } finally { if (outputStream != null) { try { outputStream.close(); } catch (IOException exception) { // Nothing much to do } } } } }

• How to make a web browser with tabbed browsing with vb 2008?

  - by felixd68

  I've tried multiple times to create a web browser with tabbed browsing. I know that I have to use "tab control". I have succeeded in creating a semi-tabbed browsing. People are able to add new tabs, but the webbrowser component only appears in one tab page. Coding: Form1_Load: Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Dim Browse As New WebBrowser TabControl1.TabPages.Add(1, "TabPage" & i) TabControl1.SelectTab(1 - 1) Browse.Name = "wb" Browse.Dock = DockStyle.Fill TabControl1.SelectedTab.Controls.Add(Browse) i = i + 1 End Sub Web Browser Component Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) url.Text = e.Url.ToString() 'your url text box will show the actual url of the page after the page is fully loaded url.Text = e.Url.ToString Me.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).DocumentTitle & " - Webbrowser's name" TabControl1.SelectedTab.Text = CType(TabControl1.SelectedTab.Controls.Item(0), WebBrowser).DocumentTitle End Sub

If someone already looking this topic? PS: the reason why I'm asking and not coding my self is time, I need to get this method quick. Thank you, all success solutions from my side will be posted here for others.

• Can somebody explain in a few sentences how these technologies relate: Flex, Flash, Air, ActionScrip

  - by SimpaCar

  I've read about each of these but I still don't understand how they all inter-operate, which are competing technologies, or even really what each of them is distinctly. Flash, Air, Flex... Are these all "containers"/JVM-like runtime environments, in which ActionScript code runs? SWF,FLV,AIR... Are these competing file formats which a Flash, Air or Flex runtime environment executes? ActionScript is a C-like language which compiles to SWF, FLV or AIR files? Sorry, with all the marketing around these terms, some of which are used interchangeably, I am quite lost. Suppose I wanted to write an AIR application... what would that entail? Writing ActionScript, compiling it to a SWF, and then installing the AIR runtime to execute it? How's that different than Flash? If I want to play AIR applications do I need a separate AIR runtime or does Flash execute AIR apps?

• Developing Mobile App (Iphone,Blackberry,Android) for an existing website

  - by soodos

  Hey Guys I have a website and am planning to develop a mobile version of it for the iphone, blackberry and android. My website is a social network built on PHP Zend framework. Now all these mobile apps are going to be having the same functionality like the website. I am little ignorant about this - but from a high level I understand that all these mobile apps should not have to write any backend logic. For every functionality - they will simply make a web service API call to interact with the backend. So does that mean, for every functionality I need to create a web service method. Can the existing code be re used - I'm a little lost - Can someone shed some light on this matter or point me in the right direction (like some articles) Thanks

• How to "kill" background worker completely?

  - by Ken Hung

  Hi All, I am writing a windows application that runs a sequence of digital IO actions repeatedly. This sequence of actions starts when the user click a "START" button, and it is done by a background worker in backgroundWorker1_DoWork(). However, there are occasions when I get the "This backgroundworker is currently busy......." error message. I am thinking of implementing the following in the code, by using a while loop to "kill" the background worker before starting another sequence of action: if (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); while (backgroundWorker1.IsBusy == true) { backgroundWorker1.CancelAsync(); } backgroundWorker1.Dispose(); } backgroundWorker1.RunWorkerAsync(); I think my main concern is, will the backgroundWorker1 be "killed" eventually? If it will, will it take a long time to complete it? Will this coding get me into an infinite loop?

• Mixin or Trait implementation in AS3?

  - by Brian Heylin

  I'm looking for ideas on how to implement a Mixin/Trait style system in AS3. I want to be able to compose a number of classes together into a single object. Of course this is not a language level feature of AS3, but I'm hoping that there is maybe some way to do this using prototype based techniques or maybe some bytecode hacking that I believe AsMock uses to implement it's functionality. An existing Java example is Qi4J where the user define interfaces that the Qi4j framework implements based on metadata tags and coding by convention. Has anyone any ideas on how to get the Mixin/Trait concept working within AS3?

• Native Mouse events with Flash and Selenium

  - by Dan at Demand

  I understand that Selenium does not support Flash, but it is my understanding that I should be able to do some simplistic testing of Flash by using Selenium's built in native mouse support and doing mouse up/down events based on coordinates. Is this correct? I can't seem to get it working. I'm trying to test on this page: http://mandy-mania.blogspot.com/2010/04/sneak-peek-of-final-season-of-lost-dvd.html and all I'm trying to do is click on the flash object so it plays the video. I've tried all sorts of commands, MouseOver, MouseDown, MouseDownAt, MouseUp, MouseUpAt, etc. So, I'm wondering if this just theoretically doesn't work or if I'm just doing something wrong. The xpath I'm using is //object[@id='player'], although I've tried a number of different combinations. And yes, I've also tried just the straight click command. Any suggestions? Thanks!

• C# Operator Overloading post-fix increment

  - by Victor

  I'm coding a date class and am having trouble with the post-fix increment (the prefix increment seems fine). Here is the sample code: public class date { int year, month, day; public date(int d, int m, int y) { day = d; month = m; year = y; } static public date operator ++(date d) { return d.Next(d); } } The method "Next(date d)" takes a date and returns tomorrows date (I left it out for brevity). I'm to young in C# to understand why the prefix is fine but postfix increment does nothing. But remember in C++ we would have to have two methods instead of just one - for prefix and postfix increments. Also no errors or warnings on compile.

• Table and Column names causing problems

  - by craig

  I have an issue when the T4 linq templates generate the classes for my MySql db using subsonic 3. It looks like one of our table names "operator" is causing problems in the Context.cs generated class. In the following line of code in Context.cs Visual Studio sees <operator> as a c# operator and generates a compilation error of "Type expected" public Query<operator> operators { get; set; } Is there anyway I can work around this without having to rename my database table and column names? For example hard coding something in Settings.ttinclude to use or map different names to specific db tables and columns?

• Where to get MSDN Help Viewer for 2010 like earlier MSDN with Index, Tree and one window?

  - by Akash Kava

  I upgraded to Visual Studio 2010 RC, and I remember filling one big form for MSDN help improvement campaign and I was wondering I will get to see a Help Viewer like MSDN included in Visual Studio 2008, which included One Program (Not IE), Index and the way to view preferred language setting. Google results shows that there were headlines that Microsoft Help Viewer released for 2010 RC, but where is it? is it the same one which opens in IE and has absolute difficult way to view it? Current MSDN opening in IE is so inconvenient, there is no index, there is no grouping of content, like I typed search for TextBox and it showed up for ASP.NET, WinForms and I got lost to find out the reference in multiple pages for search results.
