  • Cocoa Basic HTTP Authentication : Advice Needed..

    - by Kristiaan
    Hello all, im looking to read the contents of a webpage that is secured with a user name and password. this is a mac OS X application NOT an iphone app so most of the things i have read on here or been suggested to read do not seem to work. Also i am a total beginner with Xcode and Obj C i was told to have a look at a website that provided sample code to http auth however so far i have had little luck in getting this working. below is the main code for the button press in my application, there is also another unit called Base64 below that has some code in i had to change to even get it compiling (no idea if what i changed is correct mind you). NSURL *url = [NSURL URLWithString:@"my URL"]; NSString *userName = @"UN"; NSString *password = @"PW"; NSError *myError = nil; // create a plaintext string in the format username:password NSMutableString *loginString = (NSMutableString*)[@"" stringByAppendingFormat:@"%@:%@", userName, password]; // employ the Base64 encoding above to encode the authentication tokens char *encodedLoginData = [base64 encode:[loginString dataUsingEncoding:NSUTF8StringEncoding]]; // create the contents of the header NSString *authHeader = [@"Basic " stringByAppendingFormat:@"%@", [NSString stringWithCString:encodedLoginData length:strlen(encodedLoginData)]]; //NSString *authHeader = [@"Basic " stringByAppendingFormat:@"%@", loginString];//[NSString stringWithString:loginString length:strlen(loginString)]]; NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL: url cachePolicy: NSURLRequestReloadIgnoringCacheData timeoutInterval: 3]; // add the header to the request. Here's the $$$!!! [request addValue:authHeader forHTTPHeaderField:@"Authorization"]; // perform the reqeust NSURLResponse *response; NSData *data = [NSURLConnection sendSynchronousRequest: request returningResponse: &response error: &myError]; //*error = myError; // POW, here's the content of the webserver's response. NSString *result = [NSString stringWithCString:[data bytes] length:[data length]]; [myTextView setString:result]; code from the BASE64 file #import "base64.h" static char *alphabet = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+-"; @implementation Base64 +(char *)encode:(NSData *)plainText { // create an adequately sized buffer for the output. every 3 bytes // become four basically with padding to the next largest integer // divisible by four. char * encodedText = malloc((((([plainText length] % 3) + [plainText length]) / 3) * 4) + 1); char* inputBuffer = malloc([plainText length]); inputBuffer = (char *)[plainText bytes]; int i; int j = 0; // encode, this expands every 3 bytes to 4 for(i = 0; i < [plainText length]; i += 3) { encodedText[j++] = alphabet[(inputBuffer[i] & 0xFC) >> 2]; encodedText[j++] = alphabet[((inputBuffer[i] & 0x03) << 4) | ((inputBuffer[i + 1] & 0xF0) >> 4)]; if(i + 1 >= [plainText length]) // padding encodedText[j++] = '='; else encodedText[j++] = alphabet[((inputBuffer[i + 1] & 0x0F) << 2) | ((inputBuffer[i + 2] & 0xC0) >> 6)]; if(i + 2 >= [plainText length]) // padding encodedText[j++] = '='; else encodedText[j++] = alphabet[inputBuffer[i + 2] & 0x3F]; } // terminate the string encodedText[j] = 0; return encodedText;//outputBuffer; } @end when executing the code it stops on the following line with a EXC_BAD_ACCESS ?!?!? NSString *authHeader = [@"Basic " stringByAppendingFormat:@"%@", [NSString stringWithCString:encodedLoginData length:strlen(encodedLoginData)]]; any help would be appreciated as i am a little clueless on this problem, not being very literate with Cocoa, objective c, xcode is only adding fuel to this fire for me.

  • Graphviz DOT arange Nodes in circles

    - by Ivo Wetzel
    OK here's my problem, I'm generating a graph of a python module, including all the files with their functions/methods/classes. I want to arrange it so, that nodes gather in circles around their parent nodes, currently everything is on one gargantuan horizontal row, which makes the thing 50k pixels wide and also let's the svg converter fail(only renders about the half of the graph). I went trough the docs(http://www.graphviz.org/doc/info/attrs.html) but couldn't find anything that seems to do the trick. So the question is: Is there a simple way to do this or do I have to layout the whole thing by myself? :/

  • Scipy sparse... arrays?

    - by spitzanator
    Hey, folks. So, I'm doing some Kmeans classification using numpy arrays that are quite sparse-- lots and lots of zeroes. I figured that I'd use scipy's 'sparse' package to reduce the storage overhead, but I'm a little confused about how to create arrays, not matrices. I've gone through this tutorial on how to create sparse matrices: http://www.scipy.org/SciPy_Tutorial#head-c60163f2fd2bab79edd94be43682414f18b90df7 To mimic an array, I just create a 1xN matrix, but as you may guess, Asp.dot(Bsp) doesn't quite work because you can't multiply two 1xN matrices. I'd have to transpose each array to Nx1, and that's pretty lame, since I'd be doing it for every dot-product calculation. Next up, I tried to create an NxN matrix where column 1 == row 1 (such that you can multiply two matrices and just take the top-left corner as the dot product), but that turned out to be really inefficient. I'd love to use scipy's sparse package as a magic replacement for numpy's array(), but as yet, I'm not really sure what to do. Any advice? Thank you very much!

  • How can I undo my last git add/commit ?

    - by dan
    I edited a file and did: git add file.py git commit -m 'fixed bug' I then edited another file and performed a minor bug fix. I don't want two commits, one after the other, showing 'bug fix'. I want one commit with 'bug fixes'. How can I undo the last add/commit and change the first commit message? I was looking at the git reset, git revert, git undo commands but I don't want to screw up my repo with a guess EDIT: Found out how to do it: http://www.gitready.com/advanced/2009/02/10/squashing-commits-with-rebase.html

  • Wordpress Template HTML CSS Layout Confusion

  • Programmatically generate video or animated GIF in Python?

    - by FogleBird
    I have a series of images that I want to create a video from. Ideally I could specify a frame duration for each frame but a fixed frame rate would be fine too. I'm doing this in wxPython, so I can render to a wxDC or I can save the images to files, like PNG. Is there a Python library that will allow me to create either a video (AVI, MPG, etc) or an animated GIF from these frames? Edit: I've already tried PIL and it doesn't seem to work. Can someone correct me with this conclusion or suggest another toolkit? This link seems to backup my conclusion regarding PIL: http://www.somethinkodd.com/oddthinking/2005/12/06/python-imaging-library-pil-and-animated-gifs/

  • JSF : able to do mass update but unable to update a single row in a datatable

    - by nash
    I have a simple data object: Car. I am showing the properties of Car objects in a JSF datatable. If i display the properties using inputText tags, i am able to get the modified values in the managed bean. However i just want a single row editable. So have placed a edit button in a separate column and inputText and outputText for every property of Car. the edit button just toggles the rendering of inputText and outputText. Plus i placed a update button in a separate column which is used to save the updated values. However on clicking the update button, i still get the old values instead of the modified values. Here is the complete code: public class Car { int id; String brand; String color; public Car(int id, String brand, String color) { this.id = id; this.brand = brand; this.color = color; } //getters and setters of id, brand, color } Here is the managed bean: import java.util.ArrayList; import java.util.List; import javax.faces.bean.ManagedBean; import javax.faces.bean.RequestScoped; import javax.faces.component.UIData; @ManagedBean(name = "CarTree") @RequestScoped public class CarTree { int editableRowId; List<Car> carList; private UIData myTable; public CarTree() { carList = new ArrayList<Car>(); carList.add(new Car(1, "jaguar", "grey")); carList.add(new Car(2, "ferari", "red")); carList.add(new Car(3, "camri", "steel")); } public String update() { System.out.println("updating..."); //below statments print old values, was expecting modified values System.out.println("new car brand is:" + ((Car) myTable.getRowData()).brand); System.out.println("new car color is:" + ((Car) myTable.getRowData()).color); //how to get modified row values in this method?? return null; } public int getEditableRowId() { return editableRowId; } public void setEditableRowId(int editableRowId) { this.editableRowId = editableRowId; } public UIData getMyTable() { return myTable; } public void setMyTable(UIData myTable) { this.myTable = myTable; } public List<Car> getCars() { return carList; } public void setCars(List<Car> carList) { this.carList = carList; } } here is the JSF 2 page: <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form id="carForm" prependId="false"> <h:dataTable id="dt" binding="#{CarTree.myTable}" value="#{CarTree.cars}" var="car" > <h:column> <h:outputText value="#{car.id}" /> </h:column> <h:column> <h:outputText value="#{car.brand}" rendered="#{CarTree.editableRowId != car.id}"/> <h:inputText value="#{car.brand}" rendered="#{CarTree.editableRowId == car.id}"/> </h:column> <h:column> <h:outputText value="#{car.color}" rendered="#{CarTree.editableRowId != car.id}"/> <h:inputText value="#{car.color}" rendered="#{CarTree.editableRowId == car.id}"/> </h:column> <h:column> <h:commandButton value="edit"> <f:setPropertyActionListener target="#{CarTree.editableRowId}" value="#{car.id}" /> </h:commandButton> </h:column> <h:column> <h:commandButton value="update" action="#{CarTree.update}"/> </h:column> </h:dataTable> </h:form> </h:body> </html> However if i just keep the inputText tags and remove the rendered attributes, i get the modified values in the update method. How can i get the modified values for the single row edit?

  • Adding functionality to any TextReader

    - by strager
    I have a Location class which represents a location somewhere in a stream. (The class isn't coupled to any specific stream.) The location information will be used to match tokens to location in the input in my parser, to allow for nicer error reporting to the user. I want to add location tracking to a TextReader instance. This way, while reading tokens, I can grab the location (which is updated by the TextReader as data is read) and give it to the token during the tokenization process. I am looking for a good approach on accomplishing this goal. I have come up with several designs. Manual location tracking Every time I need to read from the TextReader, I call AdvanceString on the Location object of the tokenizer with the data read. Advantages Very simple. No class bloat. No need to rewrite the TextReader methods. Disadvantages Couples location tracking logic to tokenization process. Easy to forget to track something (though unit testing helps with this). Bloats existing code. Plain TextReader wrapper Create a LocatedTextReaderWrapper class which surrounds each method call, tracking a Location property. Example: public class LocatedTextReaderWrapper : TextReader { private TextReader source; public Location Location { get; set; } public LocatedTextReaderWrapper(TextReader source) : this(source, new Location()) { } public LocatedTextReaderWrapper(TextReader source, Location location) { this.Location = location; this.source = source; } public override int Read(char[] buffer, int index, int count) { int ret = this.source.Read(buffer, index, count); if(ret >= 0) { this.location.AdvanceString(string.Concat(buffer.Skip(index).Take(count))); } return ret; } // etc. } Advantages Tokenization doesn't know about Location tracking. Disadvantages User needs to create and dispose a LocatedTextReaderWrapper instance, in addition to their TextReader instance. Doesn't allow different types of tracking or different location trackers to be added without layers of wrappers. Event-based TextReader wrapper Like LocatedTextReaderWrapper, but decouples it from the Location object raising an event whenever data is read. Advantages Can be reused for other types of tracking. Tokenization doesn't know about Location tracking or other tracking. Can have multiple, independent Location objects (or other methods of tracking) tracking at once. Disadvantages Requires boilerplate code to enable location tracking. User needs to create and dispose the wrapper instance, in addition to their TextReader instance. Aspect-orientated approach Use AOP to perform like the event-based wrapper approach. Advantages Can be reused for other types of tracking. Tokenization doesn't know about Location tracking or other tracking. No need to rewrite the TextReader methods. Disadvantages Requires external dependencies, which I want to avoid. I am looking for the best approach in my situation. I would like to: Not bloat the tokenizer methods with location tracking. Not require heavy initialization in user code. Not have any/much boilerplate/duplicated code. (Perhaps) not couple the TextReader with the Location class. Any insight into this problem and possible solutions or adjustments are welcome. Thanks! (For those who want a specific question: What is the best way to wrap the functionality of a TextReader?) I have implemented the "Plain TextReader wrapper" and "Event-based TextReader wrapper" approaches and am displeased with both, for reasons mentioned in their disadvantages.

  • ASP.NET treeview populate child nodes. How can I avoid a postback to server?

    - by mas_oz2k1
    I am trying to test populate on demand for a treeview. I follow the procedure from these links: http://msdn.microsoft.com/en-us/library/e8z5184w.aspx But the treeview still make a postback to the server if I expanded one of the tree nodes (If you put a breakpoint in the first line of Page_load event), thus refreshing the whole page. I am using VS2005 and Asp.net 2.0 (but the same issue occurs in VS2008) My simple test page markup is: <%@ Page Language="C#" AutoEventWireup="true" CodeFile="aspTreeview.aspx.cs" Inherits="aspTreeview" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title>Untitled Page</title> </head> <body> <form id="form1" runat="server"> <div> <table> <tr> <td style="height: 80%; width: 45%;"> <asp:Panel ID="Panel1" runat="server" BorderColor="#0033CC" BorderStyle="Solid" ScrollBars="Both"> <asp:TreeView ID="TreeView1" runat="server" ShowLines="True" PopulateNodesFromClient="True" EnableClientScript="True" NodeWrap="True" ontreenodepopulate="TreeView1_TreeNodePopulate" ExpandDepth="0"> </asp:TreeView> </asp:Panel> </td> <td style="width: 10%; height: 80%;" > <div> <asp:Button ID="Button1" runat="server" Text="->" onclick="Button1_Click" /> </div> <div> <asp:Button ID="Button2" runat="server" Text="<-" /> </div> </td> <td style="width: 136px; height: 80%"> <asp:Panel ID="Panel2" runat="server" BorderColor="Lime" BorderStyle="Solid"> <asp:TreeView ID="TreeView2" runat="server" ShowLines="True" ExpandDepth="0"> </asp:TreeView> </asp:Panel> </td> </tr> <tr> <td> </td> <td> </td> <td style="width: 136px"> </td> </tr> </table> </div> </form> </body> </html> The code behind is: protected void Page_Load(object sender, EventArgs e) { Debug.WriteLine("Page_Load started."); if (!IsPostBack) { if (Request.Browser.SupportsCallback) Debug.WriteLine("Browser supports callback scripts."); for (int i = 0; i < 3; i++) { TreeNode node = new TreeNode("ENTRY " + i.ToString()); node.Value = i.ToString(); node.PopulateOnDemand = true; node.Expanded = false; TreeView1.Nodes.Add(node); } } Debug.WriteLine("Page_Load finished."); } protected void TreeView1_TreeNodePopulate(object sender, TreeNodeEventArgs e) { TreeNode targetNode = e.Node; for (int j = 0; j < 4200; j++) { TreeNode subnode = new TreeNode(String.Format("Sub ENTRY {0} {1}", targetNode.Value, j)); subnode.PopulateOnDemand = true; subnode.Expanded = false; targetNode.ChildNodes.Add(subnode); } }

  • Are there any code libraries that validate/convert blog comments to XHTML strict?

    - by Matthew James Taylor
    I am working on a website in PHP where people can make comments similar to a blog, and I only want particular tags to be allowed. Are there any pre-built libraries that process comments and produce valid XHTML Strict code? I would need to do this in JavaScript so I can generate a live preview like Stack Overflow, plus in PHP before saving it to a MySQL database. The allowed HTML tags will be: strong, em, blockquote, and links (rel=nofollow not required) One way would be to allow people to directly enter the HTML into the comment field but I would prefer to use a simple mark up something like this (can be different - this is an example): *strong* _em_ [blockquote] http://www.link.com I want line breaks to be converted to <br />. Are there any code libraries that do the above?

  • Hover text at mouse created from firefox toolbar add-on

    - by c-square
    Hi all, I'm creating a firefox add-on, and I have a situation where if someone clicks on a specific item in my toolbarbutton menupopup, I want to display some text to appear beside the mouse for a couple seconds. I don't mean mouseover text, because when they click on the item, the I close the menupopup. I mean something like what's shown at this site: http://www.kingsquare.nl/cursormessage The normal way of doing this would be with javascript and a div that would have the text I want to show. Unfortunately, I've discovered that the toolbarbutton can't have an effect on the main window, which is where I'd need to place the div to show. I've tried getting JQuery to work and haven't been successful either. Any help would be greatly appreciated. Thanks!

  • Eclispe RCP SWT menus for Windows and Mac OS

    - by Raven
    Hi, how do I configure an Eclipse RCP command style menu to match the different menu structures on Windows and on Mac OS? Mac OS X menu example http://images.apple.com/macosx/refinements/images/services_menu_20090902.jpg Windows menu example http://www.flamingpear.com/images/psp8menu.gif In the example you see, the differences in the menu structures. For example has the Mac in its application menu the preference command, the about command and the exit command. These are under Windows usally in the file menu and the about command is found in the help menu. Is there a "standard" way of doing it with RCP programs? It should somehow be possible because Eclipse itself does it. But I can not figure out how.

  • need to align part of list item to right of li - using CSS3 Jquery column-layout

    - by Brad
    Using this jquery script to acheive CSS3 3-columns, to display a list of members alphabetically. I need it to display this way, which is does: A D B E C F Here is what I am using http://www.csscripting.com/css-multi-column/example6.php? (using this js file http://www.csscripting.com/js/v1.0beta/css3-multi-column.js) To the right of each member, it has their phone extension, which I want to float to the right, so it easy to read. I tried putting the phone extension within a div and span and when I do that, it tends to screw up at the last item in each column, by placing the person's name correctly, but their extension is the very first item in the next column. Screenshot: http://cl.ly/fq4 of what it is doing HTML Code: <div class="Article3Col"> <ul> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> <li>Doe, John <div style="float:right;"> 8317 </div> </li> <li>Doe, Sally <div style="float:right;"> 8729 </div> </li> </ul> </div> CSS: .Article3Col { column-count:3; } Any help is appreciated.

  • CurvyCorners in Wordpress Theme only rounds some corners in IE - what am I doing wrong?

    - by user346602
    Hi, I'm implementing the CurvyCorners script on a blog I'm developing. The script works in IE on some parts of the blog, but not others. I've used the following code to add it to the functions.php file (as suggested by someone smarter than me): function load_curvy_corners() { wp_enqueue_script('curvycorners', get_bloginfo('stylesheet_directory') .'/scripts /curvycorners.src.js','','',true); } add_action('init', 'load_curvy_corners'); Here is the site I'm working on: http://www.bellissimafashions.com/blog/ The container and logo area appear rounded in IE, but the navigation area is still square and seems to take awhile to load now. I don't know if this has something to do with the fact the theme I'm using (Pure II by beathemes) has placed the left side in the footer.php?

  • How to test a project with multiple python versions in a sequential way?

    - by ecolell
    I am developing a python adapter to interact with a 3rd party website, without any json or xml api (http://www.class.noaa.gov/). I have a problem when Travis CI run multiple python tests (of the The Travis CI Build Matrix) concurrently. The project is on GitHub at ecolell/noaaclass and the .travis.yml file is: language: python python: - "2.6" - "2.7" - "3.2" - "3.3" install: - "make deploy" script: "make test-coverage-travis-ci" #nosetests after_success: - "make test-coveralls" Specifically, I have a problem when at least 2 python versions were running their unit tests at the same time, because they use the same account of a website. Is there any option to specify to The Build Matrix the execution of each python version in a secuential way? Or maybe, Is there a better way to do this?

  • Don't understand the typing of Scala's delimited continuations (A @cps[B,C])

    - by jkff
    I'm struggling to understand what precisely does it mean when a value has type A @cps[B,C] and what types of this form should I assign to my values when using the delimited continuations facility. I've looked at some sources: http://lamp.epfl.ch/~rompf/continuations-icfp09.pdf http://www.scala-lang.org/node/2096 http://dcsobral.blogspot.com/2009/07/delimited-continuations-explained-in.html http://blog.richdougherty.com/2009/02/delimited-continuations-in-scala_24.html but they didn't give me much intuition into this. In the last link, the author tries to give an explicit explanation, but it is not clear enough anyway. The A here represents the output of the computation, which is also the input to its continuation. The B represents the return type of that continuation, and the C represents its "final" return type—because shift can do further processing to the returned value and change its type. I don't understand the difference between "output of the computation", "return type of the continuation" and "final return type of the continuation". They sound like synonyms.

  • 100% height on nested table cell in IE

    - by James Cooper
    I want a nested table to expand to the height of the enclosing cell. This works as expected in Firefox/Chrome/Safari, but not in IE7 or IE8. Please see the example here: http://www.bitmechanic.com/heightDemo.html The DOCTYPE is relevant. While the demo above validates as HTML 4.01 Strict, it does not render properly in IE7. If I remove the DOCTYPE entirely, or set it to HTML 3.2, it renders properly in IE. Any suggestions on how to get this to render in 4.01 (strict or loose)? The actual web site is a bit more complicated -- changing the DOCTYPE will cause all sorts of other problems. We're struggling to understand the (presumed) IE bug here and how to work around it. thanks -- James
