• Keeping iPhone application in sync with GWT application.

  - by Reflog

  Hi, I'm working on an iPhone application that should work in offline and online modes. In it's online mode it's supposed to feed all the information the user enters to a webservice backed by GWT/GAE. In it's offline mode it's supposed to store the information locally, and when connection is available sync it up to the web service. Currently my plan is as follows: Provide a connection between an app and a webservice using Protobuffers for efficient over-the-wire communication Work with local DB using Core Data Poll the network status, and when available sync the database and keep some sort of local-db-to-remote-db key synchronization. The question is - am I in the right direction? Are the standard patterns for implementing this? Maybe someone can point me to an open-source application that works in a similar fashion? I am really new to iPhone coding, and would be very glad to hear any suggestions. Thanks

• When/Why ( if ever ) should i think about doing Generic Programming/Meta Programming

  - by hotadvice

  Hi there IMHO to me OOPS, design patterns make sense and i have been able to apply them practically. But when it comes to "generic programming /meta programming" of the Modern C++ kind, i am left confused. -- Is it a new programming/design paradigm ? -- Is it just limited to "library development"? If not, What design/coding situations call for using meta programming/generic programming. -- Does using templates mean i am doing generic programming? I have googled a lot on this topic but do not grasp the BIG PICTURE fully. Also see this post. After reading dicussions here under, up till now, I am sure ( might still not be correct): a) Generic programming and meta programming are two different concepts.

• Scaling up an image

  - by codefail

  How do I fulfill the condition "returns the entire scaled up image" If I am coding this correctly, scaleColor handles individual colors, getRed handles the red, etc. I am multiplying this by the input, numTimes, which will create a new image that is scaled up it. This scaled up (increase size) is to be returned. This is what I have. Image Image::scaleUp(int numTimes) const { for (int x = 0; x < width; x++) { for (int y = 0; y < height; y++) { pixelData[x][y].scaleColor(pixelData[x][y].scaleRed(pixelData[x][y].getRed()*numTimes)); pixelData[x][y].scaleColor(pixelData[x][y].scaleGreen(pixelData[x][y].getGreen()*numTimes)); pixelData[x][y].scaleColor(pixelData[x][y].scaleBlue(pixelData[x][y].getBlue()*numTimes)); } } //return Image(); }

• Relative Paths, etc. on an Apache server

  - by Matt H.

  I'm really stuck here. I have 2 issues at once: First, my site is stored (both on local development and on live server), in a subdirectory.. as I'm working on multiple sites. i.e. /Sites/www.mysite.com/(site files here) When I'm referring to files in my web pages, I want to refer to, say, my /images directory without hard-coding every occurrence as /www.mysite.com/images/myfile.jpg Is there a way to simply redefine how the leading "/" gets interpreted by the server? Question two, concerning PHP mod_rewrite I have this set of rewrite rules. The objective is to turn www.mysite.com/faq into www.mysite.com/index.php?page="faq" RewriteEngine On RewriteCond %{REQUEST_URI} !mysite.com RewriteRule (.*) mysite.com/$1 RewriteRule ^([a-zA-Z0-9_-]+)$ /mysite.com/index.php?site=$1 RewriteRule ^([a-zA-Z0-9_-]+)/$ /mysite.com/index.php?site=$1 I don't have a problem when a url gets passed in the 2nd-to-last format (as the example above). However, if the trailing "/" is added: www.mysite.com/faq/, my external script references break: (such as src=js/script.js)...

• Bulding an multi-platform SWT application using Ant

  - by Mridang Agarwalla

  I'm writing an SWT application which can be used on Windows (32/64 bit) and Mac OSX (32/64 bit). Apart from the JRE I rely on the SWT library found here. I can find four versions of the SWT library depending upon my target platforms (as mentioned above). When building my application, how can I compile using the correct SWT Jar? If possible, I'd like to try and avoid hard-coding the Jar version, platform and architecture. The SWT Jars are named like this: swt-win32-x86_64.jar swt-win32-x86_32.jar swt-macosx-x86_32.jar swt-macosx-x86_64.jar (My project will be an open source project. I'd like people to be able to download the source and build it and therefore I've thought of including all the four versions of the SWT Jars in the source distribution. I hope this is the correct approach of publishing code relying on third-part libraries.) Thanks everyone.

• Does replacing statements by expressions using the C++ comma operator could allow more compiler opti

  - by Gabriel Cuvillier

  The C++ comma operator is used to chain individual expressions, yielding the value of the last executed expression as the result. For example the skeleton code (6 statements, 6 expressions): step1; step2; if (condition) step3; return step4; else return step5; May be rewritten to: (1 statement, 6 expressions) return step1, step2, condition? step3, step4 : step5; I noticed that it is not possible to perform step-by-step debugging of such code, as the expression chain seems to be executed as a whole. Does it means that the compiler is able to perform special optimizations which are not possible with the traditional statement approach (specially if the steps are const or inline)? Note: I'm not talking about the coding style merit of that way of expressing sequence of expressions! Just about the possible optimisations allowed by replacing statements by expressions.

• Inline javascript performance.

  - by Geromey

  I know it is better coding practice to avoid inline javascript like: <img id="the_image" onclick="do_this(true);return false;"/> I am thinking about switching this kind of stuff for bound jquery click events like: $("#the_image").bind("click",function(){ do_this(true); return false; }); Will I lose any performance if I bind a ton of click events? I am not worried about the time it takes to initially bind the events, but the response times between clicking and it happening. I bet if there is a difference, it is negligible, but I will have a ton of functions bound. I'm wondering if browsers treat the onclick attribute the same way as a bound event. Thanks

• SVN Attribution Plugin?

  - by Rosarch

  I'm using SVN with Google Code Project Hosting for a school project. As the codebase increases in size, I often find myself wondering questions like: "who originally checked in this line of code?" "who has been checking in the most code recently?" "Of the final product, how much of it was written by Person X?" "Which coder is best at adhering to the coding conventions?" Is there any plugin available to do this? (If not, I would be interested in developing one myself. Any ideas on where to get started on that?) We're using Visual Studio 2008 with the AnkhSVN plugin.

• Do the UI first with SketchFlow - Do I concern about the UI look?

  - by stacker

  There is no questions: UI-First Software Development. But what does it takes to do the UI first? I started to build a website, a complicated one, and know I start to concern about the UI. Instead to start coding html+css, I decided to start with SkecthFlow. now, I'm very confused. Do I want to build a exact sketch? meaning to think about colors, fonts make sure that the button will look like a web link... etc, or just build the application sketch flow? meaning put a textboxes and buttons. Do I need to implement every thing in SketchFlow first? I'm looking for best practice.

• Where to split a string literal

  - by quinmars

  Every time I have to split a long string literal into two (or more) pieces, because it does not fit into a single line, I have to decide if I split the text before or after a space. For example: const char * long_text1 = "This is a long text, which does not fit " "in one line"; /* or */ const char * long_text2 = "This is a long text, which does not fit" " in one line"; I tend to use the first way, but I do not have a real reason for it. So I wonder is there any advantage to favor one of them? I know this questions tend to be coding style question, but that's not my intend. I only want to know if there is a convincing reason why one of those two ways might be preferable.

• Payment Gateway Question

  - by Sphynx

  Hi, My question is not exactly about coding, and I'm not sure if I can ask it here. Nevertheless, it's somewhat related to the payment integration process. I'm going to establish a service, and deliver it through a website. When you accept payments through PayPal, they display your actual name to every client, and I'm not that comfortable with such lack of privacy. Is there any way around that? Perhaps an alternative payment gateway that doesn't display your personal info to everyone? Any suggestions welcome! Thanks

• Constant Expected "{" before ")" token

  I've got a little problem. I am applying some changes to an iOS program i wrote, but I've struck a problem. I constantly get a "Expected '{' before ')' token" warning, but my coding skills aren't good enough to find the problem. A little help would greatly be appreciated. #import "Search.h" #import "RootViewController.h" //button - (IBAction)buttonPressed)sender{ RootViewController *newview = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil]; [UIView beginAnimations:nil context:NULL]; [UIView setAnimationDuration:0.5]; [UIView setAnimationTransition:UIViewAnimationTransitionFl ipFromRight forView:self.view cache:YES]; [self.view addSubview:newview.view]; [UIView commitAnimations]; @implementation Search @end

• Typecasting a floating value or using the math.h floor* functions?

  - by nobody

  Hi, I am coding up an implementation of Interpolation Search in C. The question is actually rather simple, I need to use the floating operations to do linear interpolation to find the correct index which will eventually be an integer result. In particular my probe index is: t = i + floor((((k-low)/(high-low)) * (j-i))); where, i,j,k,t are unsigned ints, and high,low are doubles. Would this be equivalent to: t = i + (unsigned int)(((k-low)/(high-low)) * (j-i)); Is there any reason I would actually want to use math.h floor* functions over just a simple (int) typecast?

• Exception of Binding form data to object

  - by Captain Kidd

  I'm practising Spring MVC.But fail to populate command object in Controller when I use spring standard tag. For example: "form:input path="password"" But I perfectly do this with HTML standard tag. Like: "input type="text" name="password"" I wonder the way how to use Spring tag binding data. In addition, I think configuration and coding is right in my sample. protected ModelAndView onSubmit(HttpServletRequest request, HttpServletResponse response, Object command, BindException errors) throws Exception { UserFormBean b = (UserFormBean)command; System.out.println("s"); return super.onSubmit(request, response, command, errors); } <form:form commandName="command" action="/SpringFrame/register.html"> <form:input path="password"/> <!-- <input type="text" name="password"/> --> <input type="submit"/> </form:form>

• How do I use Mercurial?

  - by Derek

  I'm assuming Mercurial is for having an updated website and it archiving the old stuff? Easy to test things and such? My question is, how exactly should I get started and can somebody give me a crash course in using Mercurial and using the following techs below: Notepad++ for coding FTP PHP/MySQL Jquery & other js libraries I use windows and would like to keep things fairly simple. I'm developing 1 website currently and want some kind of CVS system in place. Or should I just stick to my current edit file in notepad++ and upload via ftp method and make a backup copy of everything every once and a while? Any thoughts? EDIT: I'm doing http://bugtracker.gttools.com/public/wiki/bluehost/Mercurial right now in order to try and 'install' it.

• Dot Net Nuke app_offline randomly being generated

  - by chelfers

  We have had multiple DNN sites running for quite a few months now without any issues. Twice in the last 3 days our sites have gone offline by the addition of the app_offline.htm file in the root dir. There is only one developer with access to the sites at a coding / directory viewing level and the file is generated at weird times times when he is NOT accessing our network. We are not publishing anything to the server ( and have not published any .net code in days ), upgrading, changing code, or even modifying content. Has anyone run into this issue?

• [grails] attaching multiple files to a domain class

  - by Emyr

  I've seen various Grails plugins which allow easier handling of file uploads, however these tend only to support a single file per form-submit. I'd like a multi-attach form where as soon as you pick one file, an extra field and button is added using JS (various sites do it like this). Do you know of any good plugins which provide elegant uploading of multiple files without excessive coding? A progress bar either per-file of for the whole process would also be very nice. I don't know to what extent I can allow GORM to handle a java.io.File field (or in this case a Collection<File>).

• Condensing multiple else if statements, referencing them from a table?

  - by Haskella

  Hi I'm about to type some 500 else if statements into my code (PHP) which have the exact same coding each: if (color=White); rgb = 255-255-255; print rgb; else if (color=Black); rgb = 0-0-0; print rgb; else if (color=Red); rgb = 255-0-0; print rgb; else if (color=Blue); rgb = 0-0-255; print rgb; [the list keeps going] I also (luckily) have a table that displays the color in the first column and rgb value in the next column for 500 of them... how do I use this to save time typing all those else if statements? Some how I have to reference the table file (made in excel, I'm guessing I'll have to save it as .csv?)

• How do I display data in a table and allow users to copy selected data?

  - by cfouche

  Hi I have a long list of data that I want to display in table format to users. The data changes when the user performs certain actions in my app, but it is not directly editable. So the user can create a reasonably big table of data, but he can't change individual cells' values. However, I do want the data to be copy-able. So I want it to be possible for the user to select some or all of the cells, and do a ctrl-C to copy the data to his clipboard, and then a ctrl-V to paste the data to an external text editor. At the moment, I'm displaying the data in a ListView with a GridView and this works perfectly, except that GridView doesn't allow one to copy data. What other options can I try? Ours is a WPF app, coding in c#.

• What has bigger priority: opacity or z-index in browsers?

  - by MartyIX

  Hi, I'm coding a "popup window" in javascript and I've come across an interesting thing: http://img91.imageshack.us/img91/4761/error01cropped.png - the navy square under the popup window is visible even though I would expect it to be hidden. The popup was added after the square so it should be on the top. CSS opacity property of the navy square is 0.3 (from what I've tried it seems that every number from the interval (0,1) would yield the same result) if I change it to 1 then it behaves as expected (i.e. the part of the square under the popup is hidden). I've tried to use z-index property and set 10 for square and 100 for the popup but it doesn't change anything. What am I missing? Why is the part of square displayed? Thanks for help!
