  • How do i style a JSON feed in my view?

    - by stephenmurdoch
    My rails app gets the following JSON feed from mixcloud and sticks the results into my index page At the moment when I do this, the entire contents of my feed are displayed unformatted in one big blob of scary looking text (without the curly JSON brackets) I only want to display specific values from the feed in the view. From the feed in question lets say for simplicity that I just wanted to display all values with a key of "url" In case I'm doing something wrong here's my code: # podcast controller def index # I'm using a class method to get the feed @feed = Podcast.feed end # podcast model def self.feed feed = JSON.parse(open("http://api.mixcloud.com/alivefrommaryhill/feed").read) end # index.html.haml .feed = @feed I can't figure out how to style the results and display only certain items from the feed. Is my approach wrong?

  • Android MapView with High Res tiles?

    - by Nemi
    I have created a simple map app that shows the local garage sales in my town. It was simple enough to create and I parse out the Google Maps (html) xml doc that the local paper uses on their google maps mashup on their website. I have noticed that the Map Tiles used in the MapView class are not as high-res as the tiles used in the real Android Google Maps app (I have a Droid). I have searched the docs and google, but I cannot find any info on this. Actually, I can't even find anyone mentioning this, which surprises me and makes me think I am missing something simple. Is this a case of Google making the APIs available, but at a lower quality, or am I missing some setting that enables higher quality map tiles?

  • GQL, Aggregation and Order By

    - by Koran
    Hi, How can GQL support ORDER BY when it does not support aggregation? The question is - if say the result of the query is more than 1000, does ORDER BY return fully ordered list or only the first 1000 items which is then ordered? To explain the question more: is conceptually MIN() same as query.orderby('asc').fetch(1)? If it is properly ordering the list, then how can it not provide COUNT(), since to properly order the list, GQL possibly has to parse through the whole list - in which case, COUNT() is not an issue at all? Or is item indexed and kept in some type of tree so that it does not need to parse it all the time?

  • russian characters not accepted in php / phpmyadmin ?

    - by Bob Deckx
    I have a website in 3 languages: english, dutch and russian. There's a little CMS where the user can update the text on the website. everything works good, except for the russian text.. If I enter any russian text in the form in the CMS, I get "????" in the phpmyadmin database and on the website. I am completely new to charsets, it's the first time I am building a website in a language that is not supported like in this case.. Could someone please tell me what's the problem here? and what I have to do to make this work in russian language?

  • What's wrong with my markdown syntax? Broken in stackoverflow and bluecloth...

    - by nfm
    I just wrote some markdown and it doesn't seem to render correctly. Is it legal syntax to have an ordered list, followed by newlines, then followed by an unordered list? Or is this a bug in bluecloth? For example: 1. One 2. Two 3. Three * Apple * Banana * Carrot Bluecloth creates a single <ul> and nests apple, banana and carrot as <li>'s under it. Stackoverflow's post editor (wmd?) does this too. Am I just doing it wrong? Surely this is a common usage case...

  • How to call superconstructor in a neat way

    - by sandis
    So here is my code: public MyClass (int y) { super(y,x,x); //some code } My problem is that in this case i want to generate a 'x' and sent to the super constructor. However the call to the superconstructor must be the first line in this constructor. Of course I could do something like this: int x; { x = generateX(); } But this feels ugly, and then the code will run no matter what constructor I use, which feels not so nice. Right now I am consider encapsulating my whole object in another object that only calculates x and then starts this object. Is this the best approach?

  • correct way to turn EAR module into OSGI bundle

    - by Osw
    Greetings to all! There is a necessity to turn part of EAR (namely - war) into OSGI bundle and retain it's interoperability. Glassfish 3.0.1 already has osgi-web-container module and I succeeded to deploy standalone OSGI war. But in case of of ex-enterprise war it looks a bit difficult to me. What do I do with EJB calls from inside future OSGI war? Is it enough to replace @EJB injections with true JNDI lookups? What about APIs and libraries shared across EAR? I could split and rearrange them, but still I will have at least one jar needed by both EAR and OSGI war. Duplicate, make it as OSGI-bundle itself and make it available to ear somehow, place it GF domain's library path? Any other ideas, advices which could make that hybrid working? Many thanks in advance, Osw

  • PostgreSQL - select only when specific multiple apperance in column

    - by Horse SMith
    I'm using PostgreSQL. I have a table with 3 fields person, recipe and ingredient person = creator of the recipe recipe = the recipe ingredient = one of the ingredients in the recipe I want to create a query which results in every person who whenever has added carrot to a recipe, the person must also have added salt to the same recipe. More than one person can have created the recipe, in which case the person who added the ingredient will be credited for adding the ingredient. Sometimes the ingredient is used more than once, even by the same person. If this the table: person1, rec1, carrot person1, rec1, salt person1, rec1, salt person1, rec2, salt person1, rec2, pepper person2, rec1, carrot person2, rec1, salt person2, rec2, carrot person2, rec2, pepper person3, rec1, sugar person3, rec1, carrot Then I want this result: person1 Because this person is the only one who whenever has added carrot also have added salt.

  • XNA 2d camera with arbitrary zoom center

    - by blooop
    I have a working 2D camera in XNA with these guts: ms = Mouse.GetState(); msv = new Vector2(ms.X, ms.Y); //screenspace mouse vecor pos = new Vector2(0, 0); //camera center of view zoom_center = cursor; //I would like to be able to define the zoom center in world coords offset = new Vector2(scrnwidth / 2, scrnheight / 2); transmatrix = Matrix.CreateTranslation(-pos.X, -pos.Y, 0) * Matrix.CreateScale(scale, scale, 1) * Matrix.CreateTranslation(offset.X, offset.Y, 0); inverse = Matrix.Invert(transmatrix); cursor = Vector2.Transform(msv, inverse); //the mouse position in world coords I can move the camera position around and change the zoom level (with other code that I have not pasted here for brevity). The camera always zooms around the center of the screen, but I would like to be able to zoom about an arbitrary zoom point (the cursor in this case), like the indie game dyson http://www.youtube.com/watch?v=YiwjjCMqnpg&feature=player_detailpage#t=144s I have tried all the combinations that make sense to me, but am completely stuck.

  • C# dealing with invalid user input

    - by Zka
    Have a simple console app where user is asked for several values to input. Input is read via console.readline(). Ex Name: Fred //string Lastname: Ashcloud //string Age: 28 //int I would like to make sure that int and double types are entered and if the user enters garbage, lets him repeat the procedure. Example, if the user enters "28 years old" where age expects int the app will crash. What is the best way to check for these inputs? Right now I can only think of: while (!Int32.TryParse(text, out number)) { Console.WriteLine("Error write only numbers"); text = Console.ReadLine(); } Is there any other way to do this? try catch statements if one wants to give a more detailed feedback to the user? How in that case?

  • Debugging maven junit tests with filtered resources?

    - by hstoerr
    We are using filtered testResources in JUnit-tests that are usually executed by the maven surefire plugin. That is, the pom contains a section <build> <testResources> <testResource> <directory>src/test/resources</directory> <filtering>true</filtering> </testResource> </testResources> ... How can I run such JUnit-tests in the debugger? If I execute the tests in eclipse the tests fail since the test resources are not filtered. If the filtered test resources would be written somewhere into the target directory, I could just use this as an additional source path - but this is not the case. If I try to run the maven build in eclipse with Debug As / maven test , the build does not stop in the breakpoints. Any other ideas?

  • Replace input type=file by an image

    - by nikospkrk
    Hi, Like a lot of people, I'd like to customize the ugly input type=file, and I know that it can't be done without some hacks and/or javascript. But, the thing is that in my case the upload file buttons are just for uploading images (jpeg|jpg|png|gif), so I was wondering if I could use a "clickable" image which would act exactly as an input type file (show the dialog box, and same $_FILE on submitted page). I found some workaround here, and this interesting one too (but does not work on Chrome =/). What do you guys do when you want to add some style to your file buttons? If you have any point of view about it, just hit the answer button ;) Cheers, Nicolas

  • No Carbon Human-Interface-Toolbox in OSX 64-bit binaries?

    - by yairchu
    I get the impression that Carbon Human Interface Toolbox does not work in 64-bit binaries. Apple's documentation says: The Carbon Help Manager is not available to 64-bit applications. ... The Control Manager is not available to 64-bit applications. ... The Data Browser is not available to 64-bit applications. ... I just want to verify that: There is no work-around around this. If this is simply the case. Why don't Apple's documentation simply state it as such?

  • alternative to check, whether a value is in a set

    - by stanleyxu2005
    Hi All, I have the following code. It looks ugly, if the value equals to one of the following value then do something. var Value: Word; begin Value := 30000; if (Value = 30000) or (Value = 40000) or (Value = 1) then do_something; end; I want to refactor the code as follows: var Value: Word; begin Value := 30000; if (Value in [1, 30000, 40000]) then // Does not work do_something; end; However, the refactored code does not work. I assume that a valid set in Delphi accepts only elements with type byte. If there any good alternative to refactor my original code (besides using case)?

  • Rails gems and plugins usage in Netbeans

    - by LearnRails
    Hi, I am working with rails 2.3 with netbeans 6.5.1 on vista. I want to install more plugins from Git in netbeans like shoulda, cucumber etc. I have these questions: 1) I do not have much knowledge of Git. Is it necessary to install Git to make use of the Git plugins in netbeans? Are gems and plugins dependant on each other? 2) In case Git is needed and I do install msysgit , for example I can use the command ruby script/plugin install http://github.com/thoughtbot/shoulda.git/ to install shoulda plugin. How to make netbeans use this plugin or how to include this plugin in netbeans? 3) Is RubyMine a better IDE for Rails than Netbeans in terms of more gems and plugins availability? Thanks

  • Disallow private constructor invocation in friend function

    - by user2907032
    Is there any way to not allow private construction in friend function, In case we do have private constructor with friend function in our class. Only Static method should be responsible for object creation and other than this compiler should flash error message #include <iostream> #include <memory> using namespace std; class a { public: void see () { cout<<"Motimaa"; } static a& getinstance() { static a instance; return instance; } private: a() {}; friend void access(); }; void access () { a obj; obj.see();//still friend function can access } int main() { a::getinstance().see(); access(); return 1; }

  • one primary key column foreign key to 2 other table columns.How to resolve data entry issue.

    - by Rohit
    I have a requirement according to which I have to create a central Login system.We have 2 things Corporate and Brand each represented by tables "Corporate" and "Brand". When a corporate gets registered,corporateID is given,When a user under that corporate gets registered there is a table corporateuser in which corporateID is a foreign key and CorporateUserID is a primary key.Similarly in the case of a brand. So we have CorporateUserId and BrandUserID. Now i have a table called RegisteredUsers in which i want to have corporate as well as brand users.UserID is a primary key in this table which is a foreign key to both corporateuser as well as Branduser. now when i enter a corporateuser,I do an entry to corporateuser as well as RegisteredUsers.When i enter CorporateUserID in userID for RegisteredUsers.It gives foreign key violation error. I fully understand this error.How can i achieve this.This requirement is very rigid.Please tell a workaround

  • Nested svn repositories

    - by singles
    I got a "Project A" in repository. But in that project I'm using a library, which is hosted on Google Code. There is my question: is there any way, to have that library files "hooked" to Google Code SVN, and simultaneously my project in my repo (it's parent to that library), so I can commit library files into my repository when I decide, that outer project revision is ok? I've tried to do checkout in the library folder, files were downloaded from Google's Code repository. But I that case wasn't able to add them to my repository - they weren't visible in "Add" window.

  • Updating rows using "in" operator in "where" clause

    - by doublep
    Hi. I stumbled upon SQL behavior I don't understand. I needed to update several rows in a table at once; started with just finding them: SELECT * FROM some_table WHERE field1 IN (SELECT ...) This returned a selection of about 60 rows. Now I was pretty confident I got the subquery right, so I modified the first part only: UPDATE some_table SET field2 = some_value WHERE field1 IN (SELECT ...) In other words, this was exactly as the first query after the WHERE. However, it resulted in 0 rows updated, whereas I would expect those 60. Note that the statement above would change field2, i.e. I verified that some_value was not present in the selected rows. The subquery was a modestly complicated SQL piece with 2 (different) tables, 1 view, joins and its own WHERE clause. In case this matters, it happened with Oracle Database 10g. So, the question is, why UPDATE didn't touch the rows returned by SELECT?

  • Documenting and defining content types for a CMS or similar project

    - by Rimian
    I'm writing up some documentation on a Drupal project and my task is to define the content types and their attributes. The intended audience is project managers and developers. So it could be a high level document that gives an overview of the system. (I think that's how I describe it: high level rather than high detail) At the moment I'm using open office and bullet points but it seems like an amateurish method when I need to describe details that could be useful for a developer (me). Something like UML would describe detail but is probably more complicated than I need right now and could be too technical for others on the team. Are there any universal methods or templates that I can use to describe information in this case?

  • Redirects in RoR: Which one to use out of redirect_to and head :moved_permanently?

    - by scrr
    Hello, we are making a website that takes a generated incoming link and forwards the user who is clicking on it to another website while saving a record of the action in our DB. I guess it's basically what ad-services like AdSense do. However, what is the best way to redirect the user? I think html-meta-tag-redirects are out of question. So what other options are there? head :moved_permanently, :location => "http://www.domain.com/" This one is a 301-redirect. The next one is a 302: redirect_to "http://www.domain.com" Are there any others? And which is best to use for our case? The links are highly-dynamic and change all the time. We want to make sure we don't violate any existing standards and of course we don't want search-engines to tag us as spammers (which we are not, btw). Thanks!

  • Get the highest odds from the last update

    - by Frankie Yale
    I have these tables in a PostgreSQL database: bookmakers ----------------------- | id | name | ----------------------- | 1 | Unibet | ----------------------- | 2 | 888 | ----------------------- odds --------------------------------------------------------------------- | id | odds_type | odds_index | bookmaker_id | created_at | --------------------------------------------------------------------- | 1 | 1 | 1.55 | 1 | 2012-06-02 10:30 | --------------------------------------------------------------------- | 2 | 2 | 3.22 | 2 | 2012-06-02 10:30 | --------------------------------------------------------------------- | 3 | X | 3.00 | 1 | 2012-06-02 10:30 | --------------------------------------------------------------------- | 4 | 2 | 1.25 | 1 | 2012-05-27 09:30 | --------------------------------------------------------------------- | 5 | 1 | 2.30 | 2 | 2012-05-27 09:30 | --------------------------------------------------------------------- | 6 | X | 2.00 | 2 | 2012-05-27 09:30 | --------------------------------------------------------------------- What I am trying to query is the following: Give me the 1/X/2 odds from the latest update (created_at) from ALL bookmakers and from that last update, give me the highest odds for each odds_type ('1', '2', 'X'). On my website I display them as: Best odds right now: 1 | X | 2 -------------------- 2.30 | 3.00 | 3.22 I have to first get the latest, because the odds from the update from yesterday are no longer valid. Then from that last update, I have - in this case - 2 odds from 2 different bookmakers, so I need to get the best one for type '1','2','X'. Pseudo SQL would be something like: SELECT MAX(odds_index) WHERE odds_type = '1' ORDER BY created_at DESC, odds_index DESC But that doesn't work, because I would always get the latest odds (and not the highest/best from those latest) I hope I'm making sense.

  • Accessing identical web services using the same client

    - by Krt_Malta
    Hi. I have some web services and I am creating a web client using ws-import. When creating the client I have this line: MyServiceService service = new MyServiceService(); It works fine as it is. I have the same web services running on another server and I was wondering if I could access them using the same client. Is it possible to change the wsdl url of the client? Ctrl-Space in Eclipse gives me 2 parameters which I can enter into MyServiceService which are URL arg0 and Qname arg1. Is this what I'm looking for? And if this is the case what should I put in Qname since I didn't find any Javadoc associated and didn't find it on google neither Thanks and regards, Krt_Malta

  • printing menu in terminal and choosing an option, how to?

    - by carlos
    I'm a haskell beginner. I'm trying to make a program that shows a menu through terminal and ask user to introduce an option. Here is the code: main :: IO () main = do putStrLn "0 <- quit" putStrLn "1 <- Hello" putStr "Choose an option: " c <- getChar case c of '0' -> return () '1' -> putChar '\n' >> putStrLn "Hello World" >> main When I use this module in the ghci interpreter everything works like it's suposed to do. But if i compile this with: ghc hello.hs and run it in the terminal, it doesn't display the line "Choose an option:" before ask for a char to be introduced. I think this may be caused because of haskell lazy nature and I don't know how to fix it. Any ideas?
