• Play Video on Safari iTouch

  - by dave cohen

  I have a web site that opens iframe for video on page, page uses ajax to pull in videos from selected menu. As expected and understood, on iTouch after selecting video it shows a play button, which brings up video in another screen. However, when the video completes, it returns browser to page prior to one where video was played from. Sequence: - open Page1 - go to Page2 which offers videos to play, in iframe - play video - video completes, returns to Page1, not Page2!! Only happens on iTouch, so must be issue with how control is returned on video completion. Any suggestions? If this is not a known problem, I can work up example (currently, need account on site). Thanks Dave

• Wix Bootstrapper - difficulty detecting if software is already installed c++ redistributable, sql server ce 3.5 sp2

  - by gdeck

  I apologize if this is answered elsewhere. So far (thanks to a post from Rob Mensching), my code will detect .NET 4.0 if it's installed and it'll pass right over it. I'm not able to correctly detect Microsoft Visual C++ 2010 x86 Redistributable OR Microsoft SQL Server Compact 3.5 Service Pack 2. My code is below. I'm learning, so I would appreciate as much constructive criticism as possible. <!--Search for .NET 4.0--> <util:RegistrySearch Id="NETFRAMEWORK40" Root="HKLM" Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full" Value="Install" Variable="NETFRAMEWORK40" Result="value"/> <!--Search for Microsoft Visual C++ 2010 x86 Redistributable--> <util:RegistrySearch Id="SearchForCPP2010X86" Root="HKLM" Key="SOFTWARE\Microsoft\VisualStudio\10.0\VC\VCRedist\x86" Value="Install" Variable="CPP2010Redist" Result="exists"/> <!--Search for Microsoft SQL Server Compact 3.5 Service Pack 2--> <util:RegistrySearch Id="SearchForSQLSvrCE35SP2" Root="HKLM" Key="SOFTWARE\Microsoft\Microsoft SQL Server Compact Edition\v3.5\ENU" Value="Install" Variable="SQLSvrCE35SP2" Result="exists"/> <Chain> <!-- Install .Net 4 Full --> <PackageGroupRef Id="Net4Full"/> <!-- Install Microsoft Visual C++ 2010 x86 Redistributable --> <PackageGroupRef Id="MSVisCPP2010x86Redist"/> <!-- Install Microsoft SQL Server Compact 3.5 Service Pack 2 --> <PackageGroupRef Id="SQLExpressCE"/> </Chain> <!--Install .NET 4.0--> <PackageGroup Id="Net4Full"> <ExePackage Id="Net4Full" Name="Microsoft .NET Framework 4.0 Setup" Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" SourceFile="BootstrapperLibrary\dotNetFx40_Full_setup.exe" DetectCondition="NETFRAMEWORK40"/> </PackageGroup> <!--Install Microsoft Visual C++ 2010 x86 Redistributable--> <PackageGroup Id="MSVisCPP2010x86Redist"> <ExePackage Id="MSVisCPP2010x86Redis" Name="Microsoft Visual C++ 2010 x86 Redistributable " Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" SourceFile="BootstrapperLibrary\vcredist_x86.exe" DetectCondition="CPP2010Redist"/> </PackageGroup> <!--Install Microsoft SQL Server Compact 3.5 Service Pack 2--> <PackageGroup Id="SQLExpressCE"> <ExePackage Id="SQLExpressCE" Name="Microsoft SQL Server Compact 3.5 Service Pack 2 Setup" Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" SourceFile="BootstrapperLibrary\SSCERuntime-ENU.exe"/> </PackageGroup>

• Sign in as different user when using Integrated Windows Authentication

  - by Sam

  I have restricted access to a site by using Integrated Windows Authentication and turning off anonymous access. This way I can then show them their real name (from looking up on Active Directory and using the server variable LOGON_USER) and do other related Active Directory tasks. How can I then prompt again for their user credentials, through a 'sign in as other user' link , showing the browser prompt (like you would get on a browser like Chrome or Firefox, or if the site was not in the 'Intranet' zone in IE) rather than a Web Form? Since SharePoint offers this functionality, I assume there is a way to do this through code, but I don't know what code can do this (using C#). I can send a 401 header which makes the prompt appear, but how do you then confirm if they are logged in?

• Build a JavaScript wrapper for a rails-generated XML API?

  - by Thor Thurn

  I am working with a large website written in Ruby on Rails. Thanks to the support for REST in Rails 2, the site's business logic is all accessible via a consistent XML API. Now I want to be able to easily write one or more JavaScript frontends to the site that interact with the generated Rails XML API. Ideally, an automated wrapper for the API could be created in JavaScript, since this would minimize the effort required in writing XML processing code for the more than 500 API functions. How, then, can I automatically generate a wrapper around a given XML API in JavaScript so that it's more pleasant to work with? I've worked with solutions of this nature for Java that generate classes and methods to wrap an API, so my current thinking is that I want something of that nature for JavaScript. I'd be open to an alternative take on the problem, though.

• Mono - Uri class

  - by Jonathan.Peppers

  I am making an HttpWebRequest at a url similar to this: "http://mysite.com/search?query=my+search+string" Problem is, the Uri class escapes it with %, and the site I'm making the request against can't handle the escaped characters. (I have no control to fix the site) So tried this [Obsolete] constructor: new Uri(myUriString, true); But it did not seem to make any difference, when debugging, my Uri still got escaped. I am running this on a Mac with Mono, but I have not tried it on standard .Net on Windows to see if it has the same behavior. Is there another way to get around this issue?

• A code using SharePoint classes doesn't run on systems not having SharePoint installed

  - by Manish

  I have a window application which uses SP classes to create a site. I works fine on a system having Windows Server 2003 R2 with sharepoint installed. But it doesn't work on a system having XP installed and SharePoint not installed. The fact is that both of these systems are on a intranet. So I assumed that the NON-SP system would be able to run the code and create a site on the system having SP installed if all the required parameters (like serverLocation, domain, username, password) are provided. I did copied the DLLs to these NON-SP system and referenced them to build the project: Microsoft.SharePoint.dll microsoft.sharepoint.portal.dll Microsoft.SharePoint.Publishing.dll But this too didn't worked. What am I missing? Is my assumption wrong?

• Autocomplete server-side implementation

  - by toluju

  What is a fast and efficient way to implement the server-side component for an autocomplete feature in an html input box? I am writing a service to autocomplete user queries in our web interface's main search box, and the completions are displayed in an ajax-powered dropdown. The data we are running queries against is simply a large table of concepts our system knows about, which matches roughly with the set of wikipedia page titles. For this service obviously speed is of utmost importance, as responsiveness of the web page is important to the user experience. The current implementation simply loads all concepts into memory in a sorted set, and performs a simple log(n) lookup on a user keystroke. The tailset is then used to provide additional matches beyond the closest match. The problem with this solution is that it does not scale. It currently is running up against the VM heap space limit (I've set -Xmx2g, which is about the most we can push on our 32 bit machines), and this prevents us from expanding our concept table or adding more functionality. Switching to 64-bit VMs on machines with more memory isn't an immediate option. I've been hesitant to start working on a disk-based solution as I am concerned that disk seek time will kill performance. Are there possible solutions that will let me scale better, either entirely in memory or with some fast disk-backed implementations? Edits: @Gandalf: For our use case it is important the the autocompletion is comprehensive and isn't just extra help for the user. As for what we are completing, it is a list of concept-type pairs. For example, possible entries are [("Microsoft", "Software Company"), ("Jeff Atwood", "Programmer"), ("StackOverflow.com", "Website")]. We are using Lucene for the full search once a user selects an item from the autocomplete list, but I am not yet sure Lucene would work well for the autocomplete itself. @Glen: No databases are being used here. When I'm talking about a table I just mean the structured representation of my data. @Jason Day: My original implementation to this problem was to use a Trie, but the memory bloat with that was actually worse than the sorted set due to needing a large number of object references. I'll read on the ternary search trees to see if it could be of use.

• Learning Algorithms and Data Structures Fundamentals

  - by valya

  Can you recommend me a book or (better!) a site with many hard problems and exercises about data structures? I'm already answering project Euler questions, but these questions are about interesting, but uncommon algorithms. I hardly used even a simple tree. Maybe there is a site with exercises like: hey, you need to calculate this: ... . Do it using a tree. Now do it using a zipper. Upload your C (Haskell, Lisp, even Pascal or Fortress go) solution. Oh, your solution is so slow! Self-education is very hard then you trying to learn very common, fundamental things. How can I help myself with them without attending to courses or whatever?

• Preserve data in .net mvc

  - by Wei Ma

  I am implementing a search module with result page support paging. The example provided by NerdDinner passes pagenumber as a parameter for the Index action, and the action uses the pagenumber to perform a query each time the user hit a different page number. My problem is that my search take many more criteria such as price, material, model number etc. than just simple pagenumber. Therefore, I would like to preserve the criteria after users' first submission, so that I only have to pass the pagenumber back and forth. Using ViewData is not possible because ViewData get cleared once it is sent to the View. Is there any good way to preserve the criteria data as I wish?

• UISearchDisplayController's full-screen background intercepts touch events in iOS 7

  - by tba

  I have a UITableview that doesn't take up the whole screen (screenshot). Everything worked fine in iOS 6. But in iOS 7, when the user searches, the search result table takes up the whole view (screenshot). To fix this, I tried setting the frame manually as described in this answer. The appearance is now correct (screenshot), but now the "<" button in the top left doesn't receive tap events when the search results table is displayed. It seems the searchResultsTableView is adding a full-screen background view that is intercepting touch events. To prove this, I added this code to didShowSearchResultsTableView: controller.searchResultsTableView.superview.backgroundColor = [UIColor blueColor];` This screenshot confirms my hypothesis. How can I fix this to allow the "<" button to receive tap events? I want to avoid modifying controller.searchResultsTableView.superview so that my change doesn't break in future versions of iOS. And what change in iOS 7 caused this behavior to start happening?

• Cookie questions in Java

  - by user220201

  Hi, How do I differentiate between multiple cookies set through my site? I am setting two kinds of cookies one to see if the user has visited the site or not and an other one for authentication. How do I differentiate between these two? I get both of them when someone accesses a page after authentication. Do I add extra information to the Cookie Value or is there some other way? I understand the setName() function will change the name (from jsessionid) for every cookie from then on. Am I correct? Pav

• Develop an classic UI or be bold with a newer design?

  - by DeanMc

  Forgive me if this is the wrong place but I am curious as to how other programmers feel about this topic: I am currently working on my portfolio site, it is being designed and built in silverlight 4. I initially started off with a typical stylised e-folio theme much like a standard website in terms of layout and flow. As I work more in the concept stages something has struck me. Am I trying to shoe-horn yesterday into today? What I am talking about is UI expectations. I'm all for clean user interfaces but that does not mean they should not take advantage of new concepts in presentation right? If you where to develop a site in silverlight as your own portfolio piece would you stick to the tried and tested "website" feel or would you try to come up with a UI that is intuitive and complements the technology? I feel that UI discussions are all the more important now that all forms of web development are allowing better methods to engage the user.

• Override transparency color when converting transparent PNG to JPG

  - by Alexander Malfait

  I'm using Dragonfly to generate thumbnail images in a Rails app. I'm serving all picture images as JPG's. Now the client is uploading transparent PNG files, like this one: http://www.ibanez.co.jp/products/images/eg2010/ART120_TRF_12_02.png Dragonfly uses RMagick to convert these images to JPG. The problem is that it converts the PNG images to JPG with a black background, and my site's design requires a white background. I've tried to override it like this: encoded_image = Magick::Image.from_blob(image.data).first if encoded_image.format.downcase == format image # do nothing else encoded_image.format = format encoded_image.background_color = "white" encoded_image.transparent_color = "white" encoded_image.to_blob end But the produced JPG images still contain a black background. Does anyone know how to beat RMagick into using a white background when converting the transparent layer? I know I could just serve as PNG, but then the images are 10 times as large, and the site is already pretty bandwidth heavy.

• Must See Conference Videos for Python/Django Developers

  - by Koobz

  There's lots of good conference videos online regarding Python and Django development. Instead of watching ST:TNG at the computer, I figure it'd more productive to hone my knowledge . Fire away with some of your most inspiring and educational Python, Django, or simply programming related talks. Provide an explanation of why you found the talk useful. Examples: James Bennet on Re-usable Apps - Got me to take a serious look at django apps. Put together a fairly robust site in two days afterwards with django-cms, django-photologue, django-contact-form. Good advice on when your app is crossing boundaries and why it's good to err on the site of 'make it a separate app.'

• Encrypt text using a number

  - by Adam Matan

  Project Euler I have recently begun to solve some of the Project Euler riddles. I found the discussion forum in the site a bit frustrating (most of the discussions are closed and poorly-threaded), So I have decided to publish my Python solutions on launchpad for discussion. The problem is that it seems quite unethical to publish these solutions, as it would let other people gain reputation without doing the programming work, which the site deeply discourages. My Encryption problem I want to encrypt my answers so that only those who have already solved the riddles can see my code. The logical key would be the answer to the riddle, which is always numeric. In order to prevent brute-force attacks on my answers, I want to find an encryption algorithm that takes a significantly long time (few seconds) to run. Do you know any such algorithm? I would fancy a Python package, which I can attach to the code, over an external program that might have portability issues. Thanks, Adam

• How to make .NET WebForm Routing work with Authorization

  - by jakmas

  I have routes that are being registered from the database into an asp.net website (non MVC). The routes register fine, they all work when I am logged in. What I am trying to do is create a landing page based on some route data: Page is [site]/landing/dell The route looks like: "landing/{client}" and it routes to my page Login.aspx, in there I get the client out of the route, then display some custom brand data based on the value. In my web.config, I have my authentication mode set to forms, with my loginUrl = "Login.aspx" When the user does not have the authorization cookie, it redirects the user to: [site]/Login.aspx?ReturnUrl=%2flanding%2fdell instead of keeping the route url, and displaying the correct data. The IIS server actually does not even process the route at all, just sends the user to the Login.aspx page. I have tried several additions to my web.config: etc, and many variations, but nothing seems to work. Ideas anyone? I assume this is a common issue, and it is just not well documented.

• Wordpress podcasting with youtube video hosting

  - by Salim Fadhley

  I'm trying to build a site based on Wordpress for a client. Eventually it will be used to publish videos which could be hosted locally, but to reduce costs it would be nicer if we could host all our videos on somewhere like YouTube or Vimeo. I'm looking for a plugin or a way of hacking an existing plugin in order to achieve this. The idea is that when we list a new item on the site, users of iTunes / iPod and any other (more) standards compliant podcatcher should be able to view the video. Ideally I'd like to get away without writing a single line of code, but that may not be possible. The best solution for me is the one which requires the least amount of work!

• Specifying different page base classes for different directories in your web.config file

  - by gbinflames

  I have a website (coded in vb.net) with an "admin" section (the admin section being a folder in the actual site)... So in every page of the site I'm using my own custom class as the page base (which has been set in the web.config file) but I want to inherit from different class for the files in the "admin" folder... Is there any way to inherit different classes for pages in different folders using the web.config or some other equally as global method? (meaning some other way than inheriting on a per page basis.)

• Apache 13 permission denied in user's home directory

  - by Dave

  Hi, My friend's website was working fine until he moved the document root from /var/www/xxx to /home/user/xxx Apache give 13 permission denied error messages when we try to access the site via a web browser. The site is configured as a virtual directory. All the Apache configurations were unchanged (except for the directory change). We tried to chmod 777 /home/user/xxx, chown apache /home/user/xxx. But they didn't work. Is there some kind of security feature set on the user's home directories? The server OS is CentOS (Godaddy VPS). Any help is appreciated! Thanks!

• c++ class member functions selected by traits

  - by Jive Dadson

  I am reluctant to say I can't figure this out, but I can't figure this out. I've googled and searched stackoverflow, and come up empty. The abstract, and possibly overly vague form of the question is, how can I use the traits-pattern to instantiate non-virtual member functions? The question came up while modernizing a set of multivariate function optimizers that I wrote more than 10 years ago. The optimizers all operate by selecting a straight-line path through the parameter space away from the current best point (the "update"), then finding a better point on that line (the "line search"), then testing for the "done" condition, and if not done, iterating. There are different methods for doing the update, the line-search, and conceivably for the done test, and other things. Mix and match. Different update formulae require different state-variable data. For example, the LMQN update requires a vector, and the BFGS update requires a matrix. If evaluating gradients is cheap, the line-search should do so. If not, it should use function evaluations only. Some methods require more accurate line-searches than others. Those are just some examples. The original version instatiates several of the combinations by means of virtual functions. Some traits are selected by setting mode bits. Yuck. It would be trivial to define the traits with #define's and the member functions with #ifdef's and macros. But that's so twenty years ago. It bugs me that I cannot figure out a whiz-bang modern way. If there were only one trait that varied, I could use the curiously recurring template pattern. But I see no way to extend that to arbitrary combinations of traits. I tried doing it using boost::enable_if, etc.. The specialized state info was easy. I managed to get the functions done, but only by resorting to non-friend external functions that have the this-pointer as a parameter. I never even figured out how to make the functions friends, much less member functions. Perhaps tag-dispatch is the key. I haven't gotten very deeply into that. Surely it's possible, right? If so, what is best practice?

• Internet Explorer to Firefox javascript migration library - does one exist?

  - by Brad

  I am working on a legacy ASP.NET web site that is highly dependent on Internet Explorer. I would like to migrate it to non-IE browsers. I know there are a large amount of differences (as detailed at quirksmode.org, etc.), so I'm searching for a javascript library that can help minimize the amount of source I'd have to change. I'm hoping that my lack of success in finding such a beast so far means that I'm just a bad google-er, and not that I'm just going to have to slog through coming up with replacements/workarounds for all of IE's proprietary functionality that this site currently uses (it uses quite a bit). Any help you can provide will be greatly appreciated. Thanks!
