• Replacing text with a link in jQuery

  - by Eli

  I'm trying to replace a small part of text in a large HTML document with my own element which I create on the fly. The text may be a huge bulk of text, html, images, what-ever, and what I want is to find the first (or all) the position of a certain string, and replace it with an element that I create using $('< span'). Using simple text.replace('the string', $('< span')); doesn't do the trick (I'm left with [object Object] and not the actual < span that I want. The reason I don't just inject direct HTML is because I want to retain all the binds that are related to the object I'm creating. and doing a replace with a custom ID, and then attaching binds to the ID after the HTML has been altered, seems a bit dirty. Thanks for the help! :)

• Payment Gateways for Mid-Sized Business?

  - by Eric

  My company is a bit unhappy with the support we've been getting from Cybersource and we're about to embark on a billing re-write so we're taking the opportunity to look at other gateways. Anyone have any positive or negative experiences they'd like to share? I'd rather not hear about small website gateways like paypal, we run tens of thousands of transactions and millions a year. If you know, I'd love to hear how much you're paying in transaction/gateway fees too. We're primarily a .NET shop if you'd like to speak to a particular API. Gateway must support the big 4 credit cards (mc, visa, disc, amex) and ACH. Thanks in advance for the help from the hive mind. :)

• What is the most efficient method to find x contiguous values of y in an array?

  - by Alec

  Running my app through callgrind revealed that this line dwarfed everything else by a factor of about 10,000. I'm probably going to redesign around it, but it got me wondering; Is there a better way to do it? Here's what I'm doing at the moment: int i = 1; while ( ( (*(buffer++) == 0xffffffff && ++i) || (i = 1) ) && i < desiredLength + 1 && buffer < bufferEnd ); It's looking for the offset of the first chunk of desiredLength 0xffffffff values in a 32 bit unsigned int array. It's significantly faster than any implementations I could come up with involving an inner loop. But it's still too damn slow.

• Simple user control for conditionally rendering nested HTML

  - by Goyuix

  What I would like to do, is be able to pass two attributes to a user control, a ListName and a Permission, like so: <uc:check id="uc" List="Shared Documents" Permission="OpenItems" runat="server"> <!-- have some HTML content here that is rendered if the permission is true --> </uc:check> Then in the actual check user control, have something similar to: <%@ Control language="C#" ClassName="check" %> <% // determine permission magic placeholder if (DoesUserHavePermissions(perm)) { // render nested HTML content } else { // abort rendering as to not show nested HTML content } %> I have read the page on creating a templated control on MSDN, and while that would work - it really seems to be a bit overkill for what I am trying to do. Is there a control that already renders content based on a boolean expression or a simpler template example? http://msdn.microsoft.com/en-us/library/36574bf6.aspx

• interface as a method parameter in Java

  - by PeterYu

  Hi all, I had an interview days ago and was thrown a question like this. Q: Reverse a linked list. Following code is given: public class ReverseList { interface NodeList { int getItem(); NodeList nextNode(); } void reverse(NodeList node) { } public static void main(String[] args) { } } I was confused because I did not know an interface object could be used as a method parameter. The interviewer explained a little bit but I am still not sure about this. Could somebody enlighten me?

• UITableViewController setting delegates and datasource

  - by the_great_monkey

  Hi iOS gurus, I'm a little bit confused about UITableViewController... As far as I concern they are typically the delegate and datasource of the UITableView (although it can be made such that they are different). However in some cases, like when embedding a UITableViewController in a UITabBarViewController in Interface Builder, we initiate our table view controller in IB. Therefore in my understanding, the default initialiser is being called. But in this case, I have this piece of code: @interface Settings : UITableViewController { } And in the IB I see that the delegate and datasource of the UITableView is hooked up to this class. My question is, why is it that we don't need to explicitly say that it is following: @interface Settings : UITableViewController <UITableViewDelegate, UITableViewDataSource> { } And in the .m file: - (void)viewDidLoad { [super viewDidLoad]; [tableView setDelegate:self]; [tableView setDataSource:self]; } I have indeed stumbled upon some cases where I have to explicitly code the above a few times to make something work. Although it is still a mystery for me as of why it is needed...

• Animation on single UIWebView

  - by Shri

  I have searched quite a bit(sample one, Sample two) but cant seem to get the correct answer. I have a webview on my XYZ view controller class. When i press on a button, it takes an URL from an array and re-loads the same webview. Now I need to do the flip book animation on it. Same webview should be reloaded. That is the webview should rotate around its own axis 180/360 degree while the loading of next url is going on. Is this possible?

• Data format for content heavy iPhone app - Plist or XML?

  - by Toby

  Hello, I'm building an iPhone app that is essentially a book, it will be bundled with a lot of text-heavy content. I considered bundling the data as XML and load it when the application starts but the XML would contain a lot of nested structures and be a bit of a pain to parse. Would it be better to use a plist? I'm concerned about memory usage and plists are loaded entirely into memory - can they be parsed in chunks? Is there a maximum size to a plist and how efficient are they? I'm not sure how big the bundled content is going to be yet but I should imagine it could be anywhere from 500k to 4MB. Thanks in advance.

• VIM: Columnvise Increment inside and outside?

  - by hhh

  By outside, I want solutions that does not use Vim's scripting hacks but try to reuse certain basic *ix tools. Inside Vim stuff asks for solutions to get the column-increment with inside stuff such as scripting. 1 1 1 2 1 3 1 ---> 4 1 5 1 6 . . . . Vim has a script that does column-vise icrementing here. It has gathered about 50/50 ups and down, perhaps tasting a bit reinventing-the-wheel. How do you column-increment stuff in Vim without using such script? Then the other question is, how do you column-increment stuff without/outside Vim? Most elegant, reusable and preferrably-small wins the race!

• m and s keys do not work over vnc connection to ubuntu server

  - by Don

  I'm new at setting a lot of this up, so bear with me. I installed Ubuntu 10.4 server on a 64 bit machine. Then I added vnc so I could manage it while it's racked. I start the server, SSH to it, and run vncserver :1 At this point, all keys work fine. Next I exit out of the SSH session and fire up my client vnc app. I connect via the IP :1, enter my password, and everything seems to be fine. Now when I enter a terminal (through the vnc connection) I cannot type lowercase "s" or "m" (upper case works). I've tried on two different pc's running the vnc client, but it's the same. I also installed the latest updates from Ubuntu as of today. Thanks for any help.

• Google App Engine dev_appserver can't find PIL (I've installed it)

  - by goggin13

  I recently upgraded my Google App Engine launcher on my Mac, running OSX 10.5.8, and afterwards my projects that work with images stopped working locally. It seems to be the same problem that I had when first using GAE locally to work with images, before I installed PIL. Here is the error I get: SystemError: Parent module 'PIL' not loaded I have PIL installed. When I run python normally, I can access it and work with it as expected. I also checked to ensure that dev_appserver.py was running the same version of Python. If I open the interpreter and type sys.version I get this back: 2.5 (r25:51918, Sep 19 2006, 08:49:13) [GCC 4.0.1 (Apple Computer, Inc. build 5341)] This is identical to what I get when I display the sys.version from my projects running through dev_appserver. Any thoughts on why dev_appserver can't find the PIL module? I have been banging my head against this for a bit. Thank you!

• how do you find the exact variable of a null pointer exception

  - by OVERTONE

  I've been at this one for a bit now. I've got a null pointer exception so im guessing somethings not been initialized. AdminMessages.inbox1.setText(messageRsetArray[0]); thats my code where its targetting. but i cant find what inside it hasnt been initiazed. AdminMessages is a class which contains a JTextField called inbox1, messageRsetArray is an array which has taken variables from an array. also inbox1 is static. i coulndt get the getters and setter to work. i know its bad practice though.

• Full stack framework for Java

  - by Jonathan Barbero

  Hello everyone, I'm looking for a full stack framework (from persistency to view generation (CRUD)) for Java. I don't have experience with Rails style frameworks, like Grails, but I worked a lot with Hibernate, Struts, Spring ... I prefer a framework that let you naturally modify the business domain design with the less effort ( i.e. writing the sql querys to modify the tables and constrains, change the view pages, etc ... ). I was looking a bit about this topic, I saw Naked Objects for example but its development has stopped. So, I want to hear about your experience. Thanks in advance.

• How to use all the cores in Windows 7?

  - by Anon

  I am not sure if this belongs to Stackoverflow or Superuser but I thought I would ask here. I have a console based application written in C which currently takes about an hour to terminate in Windows 7 64-bit OS. The task manager reports that the application is using only 25% of the available CPU. I would like to reduce the run time by increasing cpu usage. Is there any way to let the application use all four cores (the laptop has Core i5) instead of just one? I am assuming that task manager reports 25% because only one core is allocated to the program.

• Yet Another Simple Retain Count Question

  - by yar

  [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected). Some guidance would help, thanks! Is it correct to not release?

• What's the best way to replace the first letter of a string in Java?

  - by froadie

  I'm trying to convert the first letter of a string to lowercase. I know there's a capitalize method, but I want to accomplish the opposite. This is the code I used: value.substring(0,1).toLowerCase() + value.substring(1) Effective, but feels a bit manual. Are there any other ways to do it? Any better ways? Any Java string functions that do it for you? I was thinking of using something like a replace function, but Java's replace doesn't accept an index as a parameter. You have to pass the actual character/substring. Another way I can think of doing it is something like: value.replaceFirst(value.charAt(0), value.charAt(0).toLowerCase()) Except that replaceFirst expects 2 strings, so the value.charAt(0)s would probably need to be replaced with value.substring(0,1)s. Is this any better? Does it matter? Is there any standard way to do this?

• Controlling a browser from Python

  - by Noio

  I am looking for a way to control a browser from Python, i.e. fill out form fields and submit them, possibly call JS functions. I've looked around a bit, but as far as I could see PyWebKitGtk only lets you show the browser as a GUI element, not interface with it. Is there a way to do this easily? I wrote my program logic in Python, and I would hate to port it to JS. Besides that, even if I'd use pure JS "bookmarklets", those wouldn't be able to read/write to my local filesystem, would they? P.S. to quell your suspicions, I'm not trying to automatically fill out forum account creation forms or something similarly spammious, though the task is technically similar. I need to crawl/scrape sites for my research project.

• generating function arguments in java

  - by aloishis89

  I'm very new to java and am working on my first Android app. I am using the webview demo as a template. I am trying to generate a random integer between 1 and 12 and then call a certain javascript function based on the result. Here's what I have: int number = 1 + (int)(Math.random() * ((12 - 1) + 1)); number = (int) Math.floor(number); String nextQuote = "javascript:wave" + number + "()"; mWebView.loadUrl(nextQuote); So mWebView.loadUrl(nextQuote) will be the same as something like mWebView.loadUrl("javascript:wave1()") I just want to know if what I have here is correct and will work the way I think it will. The application isn't responding as expected and I suspect this bit of code is the culprit.

• Python editor/IDE for OS X

  - by TheJuice

  As a (reasonably) new Python programmer, what IDEs or editors would you recommend for Python programming on OS X and why (i.e. what features/capabilities/workflow techniques really help)? I've used Xcode and played a bit with TextMate but I can't really say that either have really hit the spot for me (although TextMate's code completion is pretty neat, I think i've been spoilt with code-completion facilities provided by editors for statically-typed languages so maybe i'm subconsciously comparing apples and oranges) I'm looking to increase my efficacy with Python and any tips would be appreciated. I know people have asked similar questions for Python IDEs in general but I am specifically concentrating on OS X and the 'Mac way'. If Xcode or TextMate are thought highly of, perhaps some suggestions as to how I could get the most benefit from the tools would help.

• using helper methods in a view in rails 3

  - by Frida777

  Hello everyone, there is something that is disturbing me a bit about rails 3. i am trying to upgrade my application from rails 2 to rails 3. i followed all the steps necessary to do and things were working well for me till now except one thing: i have a helper method that is defined differently in different helpers, for example it is defined in the application_helper in one way and the same method defined in a different way in the homepage_helper, and defined differently in another helper, let's say video_helper, in addition to that, it is used in a shared view that is used throughout the application, now if i am in the homepage, i want this function to get called from the homepage_helper and if i am in the video page, the function must be called from the video_helper, based on the concept of convention in rails, this worked perfectly in rails 2 but in rails 3, the function is always called from the last helper, alphabetically ordered, that is in the example, video_helper. How can i fix this? Kindly advice. Appreciate all the help.

• Getting a "summary" of a webpage

  - by MattiasK

  I have something of a a hairy problem, I'd like to generate a couple of paragraphs of "description" of a given url, normally the start of an article. The Meta description field is one way to go but it isn't always good or set properly. It's fair to say it's a bit problematic to accomplish this from the screenscraped HTML. I had a general idea that perhaps one could scan the HTML for the first "appropriate" segment but it's hard to say what that is, perhaps something like the first paragraph containing a certain amount of text... Anyone have any good ideas? :) It doesn't have to be foolproof

• JavaScript QR Code Reader - can it be done? Or, Remote Service?

  - by Myk

  I'm doing a bit of preliminary research on an upcoming project and I have a quick question that I figure I'll throw up here while I look elsewhere, in case anyone has any experience with this. The question is simple: is it possible to read a QR code using JavaScript? Is there a remote service to which I can pass a bitmap object from a camera and do it that way? Are there currently any libraries that allow this? The project is going to be deployed to various mobile devices and we'd like to try to use Appcelerator to make it work. I know Appcelerator does expose the Camera API on its host devices, but whatever we do with it has to be able to parse QR codes. Is this something that can be done? Thanks in advance! myk

• Accordion table cell - How to dynamically expand/contract uitableviewcell?

  - by s.newave

  Hi, I am trying create an accordion type of uitableviewcell that, when the user selects the cell, it expands to display a detailed info view inline similar to how the digg app works. I initially tried replacing the current tablecell with a customcell in cellForRowAtIndex however the animation looks a bit choppy as you can see the cell being replaced and overall the effect doesnt work to well. If you look at the digg app and others who have done this it seems that they arent replacing the current cell but instead perhaps adding a subview to the cell? The original cell however doesnt seem to animate at all and only the new view accordions into the table. Does anyone have any ideas how to accomplish a similar effect?

• Can I use Blender to create 3D wall image viewer application under Linux?

  - by sgon00

  Hi, Is that possible to use Blender to create Cooliris-like 3D wall image viewer application under Linux? I don't see many people use Blender (BGE) to create desktop application, so I am wondering if this is possible. People normally use Blender for modeling/movie and game engine. I can not find a good way to create 3D application in Linux so far. I was thinking about pyQT+opengl. But I feel that is hard to do. No robust and easy-to-use qt+opengl toolkit available from my research. I know a little bit of Blender, that's why I am asking if Blender is an alternative solution. (python is preferred) The image viewer doesn't have to be windowed. It can be full screen, like a game?. I would like to add many cool effects into this application. Hopefully cooler than Cooliris which is written in flash. Thanks a lot.
