• Django openid authentication with google

  - by Zayatzz

  Hello I am looking into authenticating via google. I dont understand how it works:http://code.google.com/apis/accounts/docs/OpenID.html#Samples If i do that 2nd request by entering the data as one url with params into browser i get back XML file. Should i not get back sample response nr3? Can somebody explain this to me? The problem is, that im trying to sort through some third party app that uses google openid authentication and its not recieving authenticated users e-mail back, like in sample response 3. Alan PS i have read through similar questions and their responses and gone through pages like: http://stackoverflow.com/questions/353880/how-does-openid-authentication-works http://www.windley.com/archives/2006/04/how_does_openid.shtml http://tinisles.blogspot.com/2008/02/how-does-openid-work.html http://openid.net/pres/protocolflow-1.1.png etc..

• How to create an aspect on class, that is not a bean using Spring AOP?

  - by Ula Krukar

  Hello, I work on an legacy application, where Spring AOP (namely ProxyFactoryBean) is used. I need to add an aspect around a method of a certain class. This class is not a bean however. The AspecjJ pointcut expression would be like this: execution(* xyz.package.Class.method()) I created a MethodInterceptor and AspectJExpressionPointcut, but I don't know how make those two work together. EDIT: I do not have source code for this class, it is a 3rd party library. The instances of this class are not created by me, neither in source code, nor in spring configuration as beans. It is used internally by the library. Any help appreciated.

• How to troubleshoot dependencies not copying.

  - by AngryHacker

  I have an EXE project A, which references a class library project B (all in the same solution). Project B has a reference to about 10 3rd party DLLs (from DevExpress). All the referenced assemblies have Copy Local set to true. When I build the entire solution, the resulting DLL from project B is copied into the bin/debug of project A. However, none of the dependencies of project B get copied. I looked in the Output window during compile and all looks good. There aren't any errors. How do I troubleshoot this?

• Using XPath to access comments a flat hierachy

  - by Sebastian

  I have a given XML document (structure can not be changed) and want to get the comments that are written above the nodes. The document looks like this: <!--Some comment here--> <attribute name="Title">Book A</attribute> <attribute name="Author"> <value>Joe Doe</value> <value>John Miller</value> </attribute> <!--Some comment here--> <attribute name="Code">1</attribute> So comments are optional, but if there is one, I want to get the comment above each attribute. Using /*/comment()[n] would give me comment n, but for n=2 I would naturally get the comment of the third attribute, so there is no connection between attributes and comments Any ideas? Thanks

• AVDs that exist do not get listed in the "Target Tab"

  - by Abhi

  I am using emulator Android 2.1 with Eclipse. For few days I had the emulator working ... was able to debug... I had 2 AVDs created and was using one of them. Earlier today I had to move my classes to a different package. Ever since I did that the configuration that I had has disappeared . So now I had to create configuration - I select Android Application and then click New - gave it a name TestPrjCfg - when I go to the "Target" tab - I see "No AVD available" but when I click manager I see two AVDs listed. I tired refresh in the "Target" tab - the existing AVDs do not show up. I used the Manager and created a third AVD that did not help either. Please let me know what am I missing here? What should I do so that the existing AVDs showup in the "Target" tab- Thank you for the time and effort abhi

• How to print non-ASCII characters in Python

  - by Roman

  I have a problem when I'm printing (or writing to a file) the non-ASCII characters in Python. I've resolved it by overriding the str method in my own objects, and making "x.encode('utf-8')" inside it, where x is a property inside the object. But, if I receive a third-party object, and I make "str(object)", and this object has a non-ASCII character inside, it will fail. So the question is: is there any way to tell the str method that the object has an UTF-8 codification, generically? I'm working with Python 2.5.4.

• Problem with eastern european characters when scraping data from the European Parliaments Website

  - by Thomas Jensen

  Dear Experts I am trying to scrape a lot of data from the European Parliament website for a research project. Ther first step is the create a list if all parliamentarians, however due to the many Eastern European names and the accents they use i get a lot of missing entries. Here is an example of what is giving me troubles (notice the accents at the end of the family name): ANDRIKIENE, Laima Liucija Group of the European People's Party (Christian Democrats) So far I have been using PyParser and the following code: parser_names name = Word(alphanums + alphas8bit) begin, end = map(Suppress, "<") names = begin + ZeroOrMore(name) + "," + ZeroOrMore(name) + end for name in names.searchString(page): print(name) However this does not catch the name from the html above. Any advice in how to proceed? Best, Thomas

• Get and Set a Single Cookie with Node.js HTTP Server

  - by Corey Hart

  I want to be able to set a single cookie, and read that single cookie with each request made to the nodejs server instance. Can it be done in a few lines of code, without the need to pull in a third party lib? var http = require('http'); http.createServer(function (request, response) { response.writeHead(200, {'Content-Type': 'text/plain'}); response.end('Hello World\n'); }).listen(8124); console.log('Server running at http://127.0.0.1:8124/'); Just trying to take the above code directly from nodejs.org, and work a cookie into it.

• Is there a way to declare a variable that implements multiple interfaces in .Net?

  - by Bryan Anderson

  Similar to this Java question. I would like to specify that a variable implements multiple interfaces. For instance private {IFirstInterface, ISecondInterface} _foo; public void SetFoo({IFirstInterface, ISecondInterface} value) { _foo = value; } Requirements: I don't have the ability to add an interface to most type that would be passed in to Foo. So I can't create a third interface that inherits from IFirstInterface and ISecondInterface. I would like to avoid making the containing class generic if possible because the type of Foo doesn't have much to do with the class and the user isn't likely to know it at compile time. I need to use foo to access methods in both interfaces at a later time. I would like to do this in a compiler safe way, i.e. no trying to cast to the interface just before trying to use it. If foo does not implement both interfaces quite a bit of functionality won't work properly. Is this possible?

• SSRS Passing values between list and subreport

  - by mjmcloug

  So this is like my third SSRS question and I've only been looking at it for a day :S This question may be a little sketchy as I'm still not up with the terminology. Basically I have a list that is bound to a "Select" of SiteId's. Inside this list I have a sub report. The idea is to pass these SiteId's into the sub report one at a time to generate a report for each site Id. But I can't figure out the expression required to pass this value in? Way off the mark? or is there an answer to this question

• Simple Python Challenge: Fastest Bitwise XOR on Data Buffers

  - by user213060

  Challenge: Perform a bitwise XOR on two equal sized buffers. The buffers will be required to be the python str type since this is traditionally the type for data buffers in python. Return the resultant value as a str. Do this as fast as possible. The inputs are two 1 megabyte (2**20 byte) strings. The challenge is to substantially beat my inefficient algorithm using python or existing third party python modules (relaxed rules: or create your own module.) Marginal increases are useless. from os import urandom from numpy import frombuffer,bitwise_xor,byte def slow_xor(aa,bb): a=frombuffer(aa,dtype=byte) b=frombuffer(bb,dtype=byte) c=bitwise_xor(a,b) r=c.tostring() return r aa=urandom(2**20) bb=urandom(2**20) def test_it(): for x in xrange(1000): slow_xor(aa,bb)

• Trouble with using ActiveX control in .net windows application

  - by alex dee

  C#, visual studio 2005 I have several 3rd party activeX control. I need to use them in my .net windows application. These controls are graphical. I created a wrapper with aximp.exe for them. But it seems that something wrong. When I call some methods of wrapped activeX control == targetinvocativeexception occured. Or visual studio writes "you are attempting to write or read protected memory". I know that something wrong. But what is exactly wrong - i don't know. I find out about method CreateControl() or STAthread attribute. but it doesn't help me. What is the common problem and common solution for my type of problem ? These activex control from big and trusted company, other developers work with them.

• network drive file sharing

  - by Linc

  For the better part of 10 years + we have relied on various network mapped drives to allow file sharing. One drive letter for sharing files between teams, a seperate file share for the entire organization, a third for personal use etc. I would like to move away from this and am trying to decide if an ECM/Sharepoint type solution, or home grown app, is worth the cost and the way to go? Or if we should simply remain relying on login scripts/mapped drives for file sharing due to its relative simplicity? Does anyone have any exeperience within their own organization or thoughts on this? Thanks.

• Checking if iframe is ready to be written to

  - by Bilal Aslam

  A 3rd party script on my web page creates an iframe. I need to know when this iframe is ready, so I can manipulate its DOM. I can think of a hacky approach: repeatedly try to modify the iFrame's DOM, and return success when a change we make sticks between two attempts. For this to work, I would prefer a property I can check on the iframe repeatedly. Is there an alternative, cross-browser evented approach to knowing that the iframe is ready? E.g. can we redefine the onLoad function to call into our code (but I don't know if I can do this, since I didn't create the iframe).

• Render a partial from a task in Symfony 1.4

  - by Cryo

  I'm trying to render a partial in a Symfony task and having no luck. I found docs in 1.1 that say to just call get_partial() but apparently that's no longer readily available in 1.4. I tried loading the helper manually with sfLoader::getHelpers('Partial'); but I get "Class sfLoader not found". Any help would be greatly appreciated. For reference what I'm trying to do is generate an HTML file called 'header.html' from my global header partial used in all of my layouts for inclusion in a third-party forum I'm integrating (Simple Machines/SMF).

• Create an application that will expire after a trial period.

  - by robUK

  Hello, C# 2008 SP1 I am writing an application that I want to give to a select number of customers. What is the best solution to use so that after the trail period (1 month) the application will no longer work. I was thinking that if they are interested in purchasing the software I will give them a license key or something, to unlock the application. I am have a very limited budget as I am working on my own. So is there any free 3rd party products that does this? Many thanks for any advice,

• How do I blur (ios7 style) a section of an image in a UITableViewCell?

  - by George McKibbin

  I've got a UIImageView that takes up the whole cell and shows an image. I'd like to blur the bottom third of the view in the iOS7 style (we're targeting iOS7). There will be a label over the blurred part. The issue seems to be that I can't "screenshot" the UIImageView right as I am setting up the cell in tableView:cellForRowAtIndexPath: as it hasn't loaded yet. Although i've even tried setting up a timer for a 0.1 second delay and that also doesn't work. I've tried the stuff on http://damir.me/posts/ios7-blurring-techniques I've tried https://github.com/justinmfischer/7blur I'd like to use the new screenshotting API drawViewHierarchyInRect:afterScreenUpdates: I'd also like to use apple's sample code UIImage+ImageEffects The only thing that has worked so far has been to just put a UIToolbar in but the performance is really slow. I don't need dynamic updates. I've managed to get the following effect a few times but it has just tinted the view and hasn't actually blurred anything so I'm a bit confused.

• Rails can't render polymorphic associations to XML?

  - by ambertch

  When I render XML with an :include clause for a polymorphic association I have, it doesn't work. I end up with the XML returning the object pointers instead of the actual objects, like: <posts> #<Comment:0x102ed1540>#<Comment:0x102ecaa38>#<Comment:0x102ec7fe0>#<Comment:0x102ec3cd8> </posts> Yet as_json works! When I render JSON with :include clause, the associations are rendered correctly and I get something like: posts":[ {"type":"Comment","created_at":"2010-04-20T23:02:30-07:00","id":7,"content":"fourth comment"}, {"type":"Comment","created_at":"2010-04-20T23:02:26-07:00","id":6,"content":"third comment"}] My current workaround is using XML builder, but I'm not too comfortable with that in the long run. Does anyone happen to know about this issue? I'm kind of in a catch-22 because while XML doesn't render the associations, as_json doesn't render in a kosher json format (returns an array rather than a list of hashes as proper json should) and the deserializer I'm using on the client side would require modification to parse the json correctly.

• How to fake Azure Table Storage in .NET for Unit Testing?

  - by Erick T

  I am working on a system that uses Azure Table Storage. In other systems (e.g., SQL, File based, etc), I can write a fake that allows me to test my data persistence logic. However, I can't see an easy way to create a fake for the Azure Table Service. I could create a new IIS project that behaves the same way, but that isn't a good way to write a unit test, it is more of an integration test. Any thoughts on how to unit test data access code that uses the Azure Table Storage client? Thanks, Erick

• Android question. Is there a link to a simple example of changing the screen brightness for an activ

  - by John

  There are apparently at least three different techniques for changing screen brightness in the Android OS. Two of them no longer work post-cupcake and the third accepted technique evidently has a bug. I would like to increase screen brightness at the start of a one-view activity then turn the brightness back to the user setting at the end of the activity. No buttons, no second view or second activity. Just a maxed brightness at start and a return to original brightness setting at the end of the activity. The examples of the current technique using WindowManager.LayoutParams that I have located range from 2 lines of code WindowManager.LayoutParams lp = getWindow().getAttributes(); lp.screenBrightness = 100 / 100.0f; getWindow().setAttributes(lp); to several pages of source code and numerous activities. Is there a simple example of maxing the screen brightness at start that someone can provide a link to? Thank you for reading my question.

• EF problem with entity re-ordering and uniqueness constraint

  - by wpfwannabe

  I am using Entity Framework and I've come to an interesting stumbling block. Let's say there is a db table "Item" with "sequence" column of type int (and others of course). Column "sequence" must be unique and it is used for (re)ordering of items. EF maps this table to "Item" class with "sequence" int property. Now let's say I want to swap position of two items by mutually exchanging each other's sequence number. Upon calling SaveChanges() EF throws an exception complaining about "sequence" uniqueness. It probably generates two UPDATEs and the first one probably fails. I assume that plain SQL solution to this issue is using a third UPDATE to introduce a unique sequence value in the process but I am stuck with EF. Any thoughts?

• can I see all SQL statements sent over an ODBC connection?

  - by Dave Cameron

  I'm working with a third-party application that uses ODBC to connect to, and alter, a database. During certain failure modes, the end-results are not what I expect. To understand it better, I'd like some way of inspecting all the statements sent to the database. Is there a way to do this with ODBC? I know with JDBC I could use http://www.p6spy.com/ to see all statements sent, for example when debugging hibernate. p6spy is a "proxy" driver that records commands sent and forwards them on to the real JDBC driver. Another possibility might be a protocol sniffer that would capture statements over the wire. Although, I'm unsure if ODBC includes a standard wire protocol, or only specifieds the API. Does anyone know of existing tools that would allow me to do either of these things? Alternatively, is there another approach I could take?

• Deploying only changed part of a website with git to ftp (svn2web for git)

  - by Elazar Leibovich

  I'm having a website with many big images file. The source (as well as the images) is maintained with git. I wish to deploy that via ftp to a bluehost-like cheap server. I do not wish to deploy all the website each time (so that I won't have to upload too many unchanged files over and over), but to do roughly the following: In a git repository, mark the last deployed revision with a tag "deployed". When I say "deploy revision X", find out which files has changed between revision X and revision tagged as deploy, and upload just them. It is similar in spirit to svn2web. But I want that for DVCS. Mercurial alternative will be considered. It's a pretty simple script to write, but I'd rather not to reinvent the wheel if there's some similar script on the web. Capistrano and fab seems to know only how to push the whole revision, in their SCM integration. So I don't think I can currently use them.

• grails metaprogramming

  - by Don

  Hi, My understanding is that there are two obvious places in a Grails app where one can do meta-programming: The init closure of Bootstrap.groovy The doWithDynamicMethods closure of a plugin The meta-programming I'm referring to here should be visible throughout the metaprogramming, typical examples include adding (or replacing) methods of 3rd party classes. String.metaClass.myCustomMethod = { /* implementation omitted */ } The disadvantage of (1), is that the metaprogramming won't be applied when the application is dynamically reloaded. The disadvantage of (2) is that I need to create and maintain an entire plugin just for the sake of a little metaprogramming. Is there a better place to do this kind of metaprogramming? Thanks, Don

• inherit properties and then change some on particular site (css)

  - by Radek

  I have three menus on this test web site. I am learning css and trying all the menus inherit all properties from menu class. The second one looks different and is not clickable. I am happy with the 3rd one, just want to make it horizontal and change its position bit. Could somebody tell me why the second menu is not click-able? how I can make the third menu vertical? I thought that display: block; for li of the 3rd menu would do the trick but I do not know the css path for that li.
