    - by Max Fraser
    I am trying to use the goTo function to rotate between images, here is my basic JS: <script type="text/javascript" charset="utf-8"> $.jQTouch(); $(function () { $('.touch').live('swipe', function (event, info) { alert('called' + info.direction); var id = $(this).parent().next().attr("id"); alert(id); $.jQTouch.goTo(id, 'slide'); }); }); </script> This works great up until I get to the $.jQTouch.goTo(id, 'slide'); line and then I get the following error: $.jQTouch.goTo is not a function How do I access this goTo function?

  • Simple object creation with DIY-DI?

    - by Runcible
    I recently ran across this great article by Chad Perry entitled "DIY-DI" or "Do-It-Yourself Dependency Injection". I'm in a position where I'm not yet ready to use a IoC framework, but I want to head in that direction. It seems like DIY-DI is a good first step. However, after reading the article, I'm still a little confused about object creation. Here's a simple example: Using manual constructor dependency injection (not DIY-DI), this is how one must construct a Hotel object: PowerGrid powerGrid; // only one in the entire application WaterSupply waterSupply; // only one in the entire application Staff staff; Rooms rooms; Hotel hotel(staff, rooms, powerGrid, waterSupply); Creating all of these dependency objects makes it difficult to construct the Hotel object in isolation, which means that writing unit tests for Hotel will be difficult. Does using DIY-DI make it easier? What advantage does DIY-DI provide over manual constructor dependency injection?

  • Problem With HTML5 Application Cache Whitelist - Won't Ignore Items

    - by Ryan Donnelly
    I'm trying to use HTML5 Application Cache to speed some things up on an iPhone webapp. It works great for storing images, css and JS, but the problem is that it also tries to store the HTML. I haven't been able to get it to ignore the html and stop storing it in the cache. From what I've read, I have to "whitelist" the files and directories that I want to load no matter what. I've tried listing the files I want cached explicitly, and I've tried adding a series of things under the "NETWORK:" heading. I've tried * / /* http://mysite.com http://mysite.com/ http://mysite.com/* None of them seem to work. Is there any way to ignore HTML files by MIME-Type or anything? Any advice would be appreciated. Ryan P.S. Of course, my site is not mysite.com..I just used that for simplicity.

  • Why is there no music streaming API service?

    - by Chad Johnson
    Apple has decided to kill lala.com. I loved that site. Now, everyone has to go back to paying $0.89+ for songs from Amazon, iTunes, etc. Lame. Rhapsody would be great, except there are no clients for Mac or Linux. They do have a web interface, buy it is nothing compared to lala's web 2.0y interface. What I just don't understand is, why is there no music API streaming service out there? Basically, developers could hook the service into any desktop or web app, and then users of the app could pay $x a month (like with Rhapsody) and play any amount of music, so long as their subscription is active. Why not? Lala streamed music to web browsers, so surely it could be as secure as lala is (was), preventing music theft.

  • To be effective on your home projects is it better using the same technologies used at work?

    - by systempuntoout
    To be more productive and effective, is it better to start developing an home project using the same technologies used at work? I'm not talking about a simple hello world web page but an home project with all bells and whistles that one day, maybe, you could sell on internet. This dilemma is often subject of flames between me and a friend. He thinks that if you want to make a great home-made project you need to use the same technologies used daily at work staying in the same scope too; for example, a c++ computer game programmer should develope an home-made c++ game. I'm pretty sure that developing using the same technologies used at work can be more productive at beginning, but surely less exciting and stimulating of working with other languages\ides\libraries out of your daily job. What's your opinion about that?

  • Why is my iPhone SDK 3.2 iPad code showing a white screen?

    - by Anthony Glyadchenko
    I'm trying to get a UISplitViewController working with an iPad app. I have the table view controller linked up under the Master pane and a plain UIView under the Detail view. I also have [window addSubview:splitView.view]; in my code. For some reason I just get a white screen even though the table view controller code is properly coded and linked under my nib. Any help would be great! Thanks! Here's where you can find the code: http://drop.io/s28bu4t/asset/mydevice-hd-zip

Any help would be great. Thanks.

  • Editing remote files over SSH, using TextMate?

    - by Zachary Burt
    I LOVE using TextMate on my MacBook. It's great. Unfortunately, I want to edit some files directly on my dev server, since it's difficult to recreate the environment locally. I'm using Git, so one alternative is to just edit locally, git commit, git push, and then git merge, but that's kind of complicated every time I want to make a simple change. I'd rather just ... use another solution. One thing I tried is mounting a hard drive via MacFusion, and then loading that in an editor. But that's so freaking laggy/slow! Has anyone cooked up a better solution?

  • Setting up DomainKeys/DKIM in a PHP-based SMTP client

    - by Alex
    It looks like there are some great libraries out there to do DomainKeys signing of emails on C#/.NET, but I'm having a really hard time finding the same kind of support for PHP. Maybe I'm not looking in the right place? The only one I found is http://php-dkim.sourceforge.net/; it looks incredibly hacky and supports PHP4 only. Considering how popular PHP is, and how critical DomainKeys are for email classification as non-spam, I'd expect better tools; do you know of any? Any other tricks you'd recommend?

  • Printing elements out of list

    - by chavanak
    Hi, I have a certain check to be done and if the check satisfies, I want the result to be printed. Below is the code: import string import codecs import sys y=sys.argv[1] list_1=[] f=1.0 x=0.05 write_in = open ("new_file.txt", "w") write_in_1 = open ("new_file_1.txt", "w") ligand_file=open( y, "r" ) #Open the receptor.txt file ligand_lines=ligand_file.readlines() # Read all the lines into the array ligand_lines=map( string.strip, ligand_lines ) #Remove the newline character from all the pdb file names ligand_file.close() ligand_file=open( "unique_count_c_from_ac.txt", "r" ) #Open the receptor.txt file ligand_lines_1=ligand_file.readlines() # Read all the lines into the array ligand_lines_1=map( string.strip, ligand_lines_1 ) #Remove the newline character from all the pdb file names ligand_file.close() s=[] for i in ligand_lines: for j in ligand_lines_1: j = j.split() if i == j[1]: print j The above code works great but when I print j, it prints like ['351', '342'] but I am expecting to get 351 342 (with one space in between). Since it is more of a python question, I have not included the input files (basically they are just numbers). Can anyone help me? Cheers, Chavanak

  • What's the best way to customize / add pages to the admin generator?

    - by Guillaume Flandre
    I'm using Symfony 1.4 and Doctrine. My application's backend was built using Symfony's admin generator. It works great when I want to display basic stuff. But tehre's not a lot of documentation on how to enhance it and add new pages. Let's take an example: I want to list published items on one page and to-be-published items on another one. I've used several ways to that in my application but can't figure out what the best way is: playing with filters and then modify templates depending on where you are? creating another module calling a different table_method? some other technique I don't know about? What's the best practice here? How do you guys usually do to customize your admin?

  • Adjusting ComboBox DropDown Width in C#

    - by Jim Fell
    Hello. I have this code that adjusts the width of a comboBox drop-down: private void comboBox_DropDown(object sender, EventArgs e) { ComboBox senderComboBox = (ComboBox)sender; int width = senderComboBox.DropDownWidth; Graphics g = senderComboBox.CreateGraphics(); Font font = senderComboBox.Font; int vertScrollBarWidth = (senderComboBox.Items.Count > senderComboBox.MaxDropDownItems) ? SystemInformation.VerticalScrollBarWidth : 0; int newWidth; foreach (string s in ((ComboBox)sender).Items) { newWidth = (int)g.MeasureString(s, font).Width + vertScrollBarWidth; if (width < newWidth) { width = newWidth; } } senderComboBox.DropDownWidth = width; } It works great, except it expands the width of the drop-down to the right, whereas I would prefer it to expand to the left because the comboBox is located on the right side of my form. Any thoughts or suggestions you may have would be appreciated. Thanks.

  • Rails 3 - Nested layouts - LocalJumpError

    - by Art Shayderov
    Hi Nested layouts do not work in Rails 3. After I hit this I tried Rails Guides Example on a blank project (both ruby 1.9.1 and 1.8.7). LocalJumpError no block given on line <%= yield :stylesheets %. If you remove this line you will get the same error on the next yield statement. Could someone fix(patch) this? It's probably just a matter of calling block_given? in the right place. That would be great. Thanks Added on 4/3: Rails 3 beta 2 released. Problem fixed.

  • Is it possible to drag windows between workspaces when using Compiz?

    - by Mike Stone
    When I used Metacity, I could drag windows between workspaces using the small icon view of my workspaces. I recently started using Compiz for all the cool desktop effects, however this drag and drop feature isn't working. I use the cube effect for switching workspaces, but I noticed the wall effect doesn't allow it either. Is this just a missing feature from Compiz or is there a setting somewhere that I can enable it? I know that I can enable dragging windows across edges to the next workspace, and the expose feature to drag windows between workspaces. However, the drag and drop on the icon view is really powerful, and I would love to have it back along with all the great Compiz special effects.

  • Reading Excel spreadsheets with Delphi

    - by Bruce McGee
    I need to read from and write to Excel spreadsheets using Delphi 2010. Nothing fancy. Just reading and writing values from specific cells and ranges on different sheets. Needs to work without having Excel installed and support Excel 2007. Some things I've looked at: I've tried using ADO, which works OK for selecting everything in an entire sheet, but I haven't had much luck reading specific cells or ranges. NativeExcel looked promising, but it doesn't seem to be in active development, and they don't respond to e-mails. Axolot has a couple of products. The main product seems to be very functional, but is pricey. They have a lite version, but it doesn't support Delphi 2010. Any recommendations? Free would be great, but I'm open to a commercial solution as long as it's reliable and well supported.

  • Checking a checkbox node programmatically with jsTree

    - by Raj
    In a tree built with jsTree, I have the text within the <a> tag sitting in a variable. I would like to check that node. How can I do so? I am currently finding that node, using jQuery, and altering its class. However, this does not repair the parent node by making the parent undetermined in its class. I tried doing $('.colors').jstree("checkbox_repair"), but that didn't seem to do anything. It would be great if someone could actually answer both those questions, since they are related to the same problem. Here is a jsFiddle, illustrating the issue-- http://jsfiddle.net/thapar/5XAjU/

  • What's the best BDD framework for working with ASP.NET MVC 2 + C# 4?

    - by Soul_Master
    I just heard about BDD when I watch video of Scott Guthrie in Sweden. One of listener asked question to Scott about How VS2010 and ASP.NET MVC do to support BDD. After that, I search about BDD (Behavior Driven Development) that focus on specification more than unit testing when compares with TDD (Test Driven Development). I found some framework that work with Ruby and Java. But I do not any famous framework for .NET. Please suggest me about BDD framework and summary PROs/CONs of it. PS. Suggested BDD framework must work great on .NET 4, C# 4.0 and ASP.NET MVC 2. Thanks,

    - by Oded
    Looking back at my career and life as a programmer, there were plenty of different ways I improved my programming skills - reading code, writing code, reading books, listening to podcasts, watching screencasts and more. My question is: What is the most effective thing you have done that improved your programming skills? What would you recommend to others that want to improve? I do expect varied answers here and no single "one size fits all" answer - I would like to know what worked for different people. Edit: Wow - what great answers! Keep 'em coming people!!!

  • Collaborative Filtering Program: What to do for a Pearson Score When There Isn't Enough Data

    - by Mike
    I'm building a recommendation engine using collaborative filtering. For similarity scores, I use a Pearson correlation. This is great most of the time, but sometimes I have users that only share a 1 or 2 fields. For example: User 1{ a: 4 b: 2 } User 2{ a: 4 b: 3 } Since this is only 2 data points, a Pearson correlation would always be 1 (a straight line or perfect correlation). This obviously isn't what I want, so what value should I use instead? I could just throw away all instances like this (give a correlation of 0), but my data is really sparse right now and I don't want to lose anything. Is there any similarity score I could use that would fit in with the rest of my similarity scores (all Pearson)?

  • Restlet/Jackson works differently when object implements Serializable

    - by ravyoli
    I am sending an object with some primitive fields using Restlet with Jackson converter. Up until now it worked great. But then I needed my object to implement Serializable, because I need to store it in memcache of GAE. For some reason - when the class implements Serializable, things stop working. Restlet sends a different string representation from before, and I can't even print that string in the server. I tried printing its byte value, char-by-char and the first numbers are: 0xfffd 0xfffd 0x0000 0x0005 0x0073 0x0072 Thanks a lot!

  • ASP.net Error in Design Mode

    - by stringo0
    I just switched to VS 2010, and upgraded a previous project. I'm getting the following error on a page in design mode for 2 controls: Error Creating Control - ObjectName Object reference not set to an instance of an object. One of them is a simple label, and the other is a ajax update panel. Other pages look fine. When I build and test the app, the page renders fine in the browser and functions fine - the label functions as expected and the content in the update panel works as expected. Any ideas why I'm getting this error? I tried some of the google results to no avail. It'd be great to get this out of the way. Thanks!

  • Would a Socket Connection Outperform an Intarvaled Database Sweep and Requests?

    - by Jascha
    I'm building a small chat application to add to an existing framework. There will only be 20-50 users MAX at any one time. I was wondering if I could get away with updating a cache file containing (semi) live chat data for whichever users happen to be chatting just by performing timed queries and regular AJAX refreshes for new data as opposed to learning how to open and maintain a socket connection. I'm sure there are existing chat plug-ins out there. But I just had a hell of a time installing one and I could see building the whole damn thing taking just as much time as plugging one in. Am I off to a bad start? Thanks in advance -J (p.s. this is a semi closed network behind a php login so security isn't a great concern)

  • jQuery Delay Question

I'm just trying to accomplish haveing the .removeClass("under") delayed by a second or two when the mouse un-hovers. I don't want to delay the slideUp. Any ideas?
