  • CI controller function is ignored

    - by den-javamaniac
    Hi. I'm trying to pass through a CI tutorial (writing a simple forum) and I can't make a controller function called. To be more specific I have this in a controller: function __construct() { parent::Controller(); $this->load->helper('url'); } function index() { $data['title'] = "Wlcome to Gossip"; $data['heading'] = "Welcome to Gossip"; $data['query'] = $this->db->get('topic')->result(); $this->load->view('welcome', $data); } function topic() { echo 'testing...'; } and when I'm trying to access the /index.php/forum/topic/ uri it just prints out my index() function. Can any one point out what may cause the problem?

  • SVN user guidelines

    - by Oliver Moran
    I have been tasked with writing a set of user guidelines for SVN for developers in my company. The guidelines are to be solely from a user perspective (e.g. commit comments, when to commit) and not from an administrative perspective (e.g. when to tag, how to structure). An administrative guideline will be written in a separate document. We are an app development house involved also in embedded development. So our developers range from HTML5 and Flash to Java and C. Some of our coding involves forking very large (millions of files) code bases. Other parts involve us engaging in ground-up development. Are there any best practices for use of SVN from a user (i.e. grunt developer) perspective?

  • Pulling .live() functionality out of jQuery

    - by Daniel
    I am writing a Firefox Add-On that currently is depending on jQuery for the following things: Selectors Animations A special .live("focus") hail-mary event-catching maneuver that happens to work with jQuery 1.4.2 (but not 1.4.4) jQuery isn't well suited for functioning inside XUL, and it's a miracle we've gotten this far with it. We're trying to remove the jQuery requirements, the first two are easy (animations are simple, and we can use .querySelector() instead of jQuery), but the .live has proven impossible to do on our own. I've tried reading the source code, but I haven't been able to piece it apart. What is the jQuery .live function doing? There's clearly a lot more going on than document.addEventListener("focus"/"focusin",function_to_pick_apart_events). What else is going on here?

  • Wierd characters in exported csv files when converting

    - by Ahue
    Hey guys, I came across a problem I cannot solve on my own concerning the downloadable csv formatted trends data files from Google Insights for Search. I'm to lazy to reformat the files I4S gives me manually what means: Extracting the section with the actual trends data and reformatting the columns so that I can use it with a modelling program I do for school. So I wrote a tiny script the should do the work for me: Taking a file, do some magic and give me a new file in proper format. What it's supposed to do is reading the file contents, extracting the trends section, splitting it by newlines, splitting each line and then reorder the columns and maybe reformat them. When looking at a untouched I4S csv file it looks normal containing CR LF caracters at line breaks (maybe thats only because I'm using Windows). When just reading the contents and then writing them to a new file using the script wierd asian characters appear between CR and LF. I tried the script with a manually written similar looking file and even tried a csv file from Google Trends and it works fine. I use Python and the script (snippet) I used for the following example looks like this: # Read from an input file file = open(file,"r") contents = file.read() file.close() cfile = open("m.log","w+") cfile.write(contents) cfile.close() Has anybody an idea why those characters appear??? Thank you for you help! I'll give you and example: First few lines of I4S csv file: Web Search Interest: foobar Worldwide; 2004 - present Interest over time Week foobar 2004-01-04 - 2004-01-10 44 2004-01-11 - 2004-01-17 44 2004-01-18 - 2004-01-24 37 2004-01-25 - 2004-01-31 40 2004-02-01 - 2004-02-07 49 2004-02-08 - 2004-02-14 51 2004-02-15 - 2004-02-21 45 2004-02-22 - 2004-02-28 61 2004-02-29 - 2004-03-06 51 2004-03-07 - 2004-03-13 48 2004-03-14 - 2004-03-20 50 2004-03-21 - 2004-03-27 56 2004-03-28 - 2004-04-03 59 Output file when reading and writing contents: Web Search Interest: foobar ??????????? ? ? ? ????????? ????????? ???? ??????

  • Replace the callback for a GtkItem created from a GtkItemFactoryEntry

    - by rampion
    I'm writing a plugin that's modifying an existing UI. One thing I want to do is change what an existing menu item does. This is all using the Gtk library. The menu item (a GtkItem) is created from a GtkItemFactoryEntry (which is out of my control), and has its current behaviour defined by the callback in the GtkItemFactoryEntry. I can get handle on the menu item using gtk_item_factory_get_widget() and attach further actions to the menu item using gtk_signal_connect(), but I can't seem to disconnect the original callback using gtk_signal_disconnect() or gtk_signal_disconnect_by_func(). Is there any way I can remove or replace the original callback?

  • In python, how do I drag and drop 1 or more files onto my script as arguments with absolute path? (f

    - by chromejs10
    I am writing a simple Python script with no GUI. I want to be able to drag and drop multiple files onto my python script and have access to their absolute paths inside of the script. How do I do this in Mac, Linux, and windows? For times sake, just Mac will be fine for now. I've googled this question and only found one related one but it was too confusing. I am currently running Mac OS X Snow Leopard. Any help is much appreciated. Thanks!

  • Get selected items from explorer using C# .NET 3.5

    - by ghawkes
    I am writing a .NET 3.5 WPF application in C#. This application needs to be able to get the selected items out of Windows explorer when it is in the foreground. I already have the code working that handles a global Windows hotkey and then checks to see if the foreground IntPtr is from explorer. If so, I am able to obtain the System.Diagnostics.Process object that maps to explorer. At this point, I would like to obtain the list of selected items from explorer. Perhaps there is a Windows API function that I could pinvoke to do this? Thank you, G

  • What do you do when you hate programming?

    - by Vimvq1987
    Don't know where to ask this question. It's likely to be closed, I know. I got a hard work. Tried to code, tried to search, tried to ask. Got nothing. It make me terribly tired, and some way, I feel that in this moment, I hate programming. Some said that hard works improve yourself, yes, but not impossible-works. Is there sometimes that you hate programming? Is there sometimes that you feel so tired of writing code? How do you overcome those times?

  • How do you get 100% code coverage with guards in Haskell?

    - by dan_waterworth
    I'm trying to get (and prove) 100% test coverage for some code I'm writing in Haskell using HPC. However if I write something like this: fac n | n > 0 = n * (fac (n - 1)) | otherwise = 1 Then the second expression of the guard statement has always True tagged to it. What is the easiest way to overcome this in the general case? edit: Just to clarify. This code: fac n = if n > 0 then n * (fac (n - 1)) else 1 Works fine with HPC, (running it gives 100% code coverage). I'm basically suffering from this problem: http://hackage.haskell.org/trac/ghc/ticket/3175

  • jUnit same exception in different cases

    - by coubeatczech
    Hi, I'm writing a jUnit test for a constructor that parses a String and then check numerous things. When there's wrong data, for every thing, some IllegalArgumentException with different message is thrown. So I would like to write tests for it, but how can i recognize what error was thrown? This is how can I do it: @Test(expected=IllegalArgumentException.class) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); } and this is how I would like to be, but I don't know if it is possible to write it somehow: @Test(expected=IllegalArgumentException.class("error1")) public void testRodneCisloRok(){ new RodneCislo("891415",dopocitej("891415")); }

  • Have my UIPickerView having the same behavior than the keyboard.

    - by camilo
    Hi. So I have a UITableView where one of its rows is a UITextView. When the user is writing something to UITextView (using the keyboard) the user can scroll the tableview and select another cell. Everything works. When the user selects another cell, a datePicker appears, and the user can select a given date. I want the user to be able to scroll the tableView the same way like when the keyboard is on the screen. The problem here is that when I scroll with the picker, the table bounces back to the previous position (with some cells hidden by the picker). I assume that this happens because I add the picker to the main window, as a subview... but I'm honestly not sure... Where (and how) should I add my picker so that it "appears" where the keyboard appears? Not sure I was clear... Thanks a lot.

  • Ruby: Streaming large AWS S3 object freezes

    - by Peter
    Hi, I am using the ruby aws/s3 library to retrieve files from Amazon S3. I stream an object and write it to file as per the documentation (with debug every 100 chunks to confirm progress) This works for small files, but randomly freezes downloading large (150MB) files on VPS Ubuntu. Fetching the same files (150MB) from my mac on a much slower connection works just fine. When it hangs there is no error thrown and the last line of debug output is the 'Finished chunk'. I've seen it write between 100 and 10,000 chunks before freezing. Anyone come across this or have ideas on what the cause might be? Thanks The code that hangs: i=1 open(local_file, 'w') do |f| AWS::S3::S3Object.value(key, @s3_bucket) do |chunk| puts("Writing chunk #{i}") f.write chunk.read_body puts("Finished chunk #{i}") i=i+1 end end

  • int vs const int&

    - by Valdo
    I've noticed that I usually use constant references as return values or arguments. I think the reason is that it works almost the same as using non-reference in the code. But it definitely takes more space and function declarations become longer. I'm OK with such code but I think some people my find it a bad programming style. What do you think? Is it worth writing const int& over int? I think it's optimized by the compiler anyway, so maybe I'm just wasting my time coding it, a?

  • Delete files in C# that windows does not want me to delete?

    - by user315881
    At my company, we are writing a script to take care of simple tasks that we usually would do by hand. I am using c# to delete profiles in c:\documents and settings\, except a few. These will simply be left alone. The problem is that even with code that sets the files to normal and marks the admin user as an owner, they won't delete. They say that the quick launch folder has access denied. I am using a recursive permissions change method and I know that it works. Same thing with file attributes. Why won't it work? How do I fix this?

  • How can I modify the application file of an application that is currently running (on Linux)?

    - by Hach-Que
    I have an application running called AppFS. This application has an ext2 filesystem just attached to the end of the file (it's positioned so that the application binary exists in a 1MB spacing area, followed by the ext2 data). Now I've got FUSE embedded in the program and I've managed to extract the filesystem out of the application data into a temporary file so that FUSE can mount / use it. The problem I have now is writing the temporary file back into the application file. I get "Text file busy" presumably because the application has locked itself and won't let writes occur. Is there a way I can force the file to become unlocked so I can write data to it? (It's important to note that I'm not changing the application binary area - just rewriting the ext2 component.) It needs to be unlocked without requiring root permissions (unlocked by the same user who started the application).

  • concurrent doubly-linked list (1 writer, n-readers)

    - by Arne
    Hi guys, I am back in the field of programming for my Diploma-thesis now and stumbled over the following issue: I need to implement a thread-safe doubly-linked list for one thread writing the list at any position (delete, insert, mutate node data) and one to many threads traversing and reading the list. I am well aware that mutexes can be used to serialize access to the list, still I presume that a naive lock around any write operation will be less than optimal. I am wondering whether there are better variants. (I am well aware that 'optimal' has not much of a practical meaning as long as no exact measure/profiling are available but this is an academic thesis after all..) I am very gratefull for code-samples as well as references to academic granted these have at least a tiny bit of practical relevance. Thanks at lot

  • Is there a way to get a reference to all the paragraphs or headings in a web page in JavaScript?

    - by mattbd
    I'm writing a simple Greasemonkey script to strip out all the images, headings and paragraphs from a web page (it's because someone wants to use images of several popular websites with the images and text removed in a presentation about branding of websites). I've figured out how to do so with images by using a for loop and the document.images array like this: var i = 0; var imglngth = document.images.length; for(i=0;i<imglngth;i++) { document.images[i].style.display="none"; } However, I don't believe there's an object representing paragraphs or headers. Any suggestions as to how I could implement this?

  • C++ operator[] syntax.

    - by Lanissum
    Just a quick syntax question. I'm writing a map class (for school). If I define the following operator overload: template<typename Key, typename Val> class Map {... Val* operator[](Key k); What happens when a user writes: Map<int,int> myMap; map[10] = 3; Doing something like that will only overwrite a temporary copy of the [null] pointer at Key k. Is it even possible to do: map[10] = 3; printf("%i\n", map[10]); with the same operator overload?

  • Singly-Linked Lists insert_back and isIncreasing

    - by rezivor
    I just finished writing a program that I can add, remove or print objects to a list, but I am having difficulty implementing two more functions that is insert_back, which inserts a value to the end of a list. Also,I have to modify the representation of a List and alter whatever methods are necessary to make insert_back run in constant time: O(1). This new operation should have the signature: void List::insert_back( const Object& data ); Also, isIncreasing, For example, for a list containing head-() (11) (8) (15) (3), isIncreasing() should return false. However, it would return true when working on a list containing head- () (7) (9) (15). This new operation should have the signature: bool List::isIncreasing() const; Thank you

  • Highlighting current and previous stars on mouseover

    - by mpet
    I'm trying to make simple five star rating system using Twitter Bootstrap 3 i jQuery. For now, I'm trying to set .hover() and .mouseout() events using counter by writing this code that doesn't work: var i; for (i = 1; i <= 5; i++) { $('#overall_rating_' + i).hover(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star-empty").addClass("glyphicon-star"); }); $('#overall_rating_' + i).mouseout(function(){ $('#overall_rating_' + i).removeClass("glyphicon-star").addClass("glyphicon-star-empty"); }); } Trying to highlight current and previous stars on mouseover. The code is not complete, it would be accompanied by additional sub-counters, but this part doesn't work for now. Any better methods are welcome. What's broken here?

  • Sort objects and polymorphism

    - by ritmbo
    Suppose I have a class A. And B and C are child of A. Class A has a generic algorithm for sorting arrays of type A, so that I could use it for B and C without writing again the algorithm for each. In the algorithm, sometimes I have to swap. The problem is that I can only see the objects as type A, and if I do: A aux = array[i] array[i] = array[j] array[j] = aux I think I have a problem. Because array[i], maybe its of type B, and aux is of type A, so I think I'm losing information. I'm sure u understand this situation... how can I sort a generic array of objects using a father method algorithm?

  • Rails: What's the suggested approach to retrieve xml from an outside source

    - by Syrahn
    Rails newbie (though long time programmer) here. I'm writing an test app that retrieves data from several outside sources (think Twitter, RSS feeds, etc.) and under certain circumstances, it stores that data in a db (or presents it to the user). The data model and the views are trivial. What I'm having difficulty with is making the actual xml HTTP call to the outside source and deserialize the xml response so I can query/use it in my controller/helper. What library/gem should I use to accomplish this? I tried looking this up around the net, but only came up with some article from 2006 which, knowing how fast Rails has developed, might well be completely deprecated. Your help is much appreciated.

  • Why is the GUID structure declared the way it is?

    - by alabamasucks
    In rpc.h, the GUID structure is declared as follows: typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; BYTE Data[8]; } GUID; I understand Data1, Data2, and Data3. They define the first, second, and third sets of hex digits when writing out a GUID (XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXX). What I never understood was why the last 2 groups were declared together in the same byte array. Wouldn't this have made more sense (and been easier to code against)? typedef struct _GUID { DWORD Data1; WORD Data2; WORD Data3; WORD Data4; BYTE Data5[6]; } GUID; Anyone know why it is declared this way?

  • What's some simple F# code that generates the .tail IL instruction?

    - by kld2010
    I'd like to see the .tail IL instruction, but the simple recursive functions using tail calls that I've been writing are apparently optimized into loops. I'm actually guessing on this, as I'm not entirely sure what a loop looks like in Reflector. I definitely don't see any .tail opcodes though. I have "Generate tail calls" checked in my project's properties. I've also tried both Debug and Release builds in Reflector. The code I used is from Programming F# by Chris Smith, page 190: let factorial x = // Keep track of both x and an accumulator value (acc) let rec tailRecursiveFactorial x acc = if x <= 1 then acc else tailRecursiveFactorial (x - 1) (acc * x) tailRecursiveFactorial x 1 Can anyone suggest some simple F# code which will indeed generate .tail?
