• Comparing Clojure books

  - by Michiel Borkent

  Currently there is (afaik) one completed Clojure book available: Programming Clojure by Stuart Halloway. Two are being written and partially available at Manning: The Joy of Clojure by Fogus and Houser Clojure in Action by Amit Rathore Another one is about to be published in May: Practical Clojure (The Definitive Guide) by Luke Van der Hart Are these books more or less the same and meant as a general introduction to Clojure? Does it make sense to buy them all, or is there a risk of having three very similar books? Will there be books that go into more specialized areas of Clojure and targetted for 'intermediate' or 'advanced' Clojure programmers?

• 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?

• Javascript draw dynamic line

  - by Ranch

  Hello, I'm looking for Javascript code for letting the user draw a line (on an image). Just as the line tool in Photoshop (for example): The user clicks on the image, drags the mouse (while the line between the start point and the mouse point is dynamically drawn on mouse drag). I would also need a callable function to send the page the start and end coordinates. I've found this very nice script for area selection: http://www.defusion.org.uk/code/javascript-image-cropper-ui-using-prototype-scriptaculous/ and I've found many script for drawing lines (and other shapes in JS), but could not find what I'm looking for. Thanks

• How can I use jQuery to match a string inside the current URL of the window I am in?

  - by Jannis

  Hi, I have used the excellent gskinner.com/RegExr/ tool to test my string matching regex but I cannot figure out how to implement this into my jQuery file to return true or false. The code I have is as follows: ^(http:)\/\/(.+\.)?(stackoverflow)\. on a url such as http://stackoverflow.com/questions/ask this would match (according to RegExr) http://stackoverflow. So this is great because I want to try matching the current window.location to that string, but the issue I am having is that this jQuery/js script does not work: var url = window.location; if ( url.match( /^(http:)\/\/(.+\.)?(stackoverflow)\./ ) ) { alert('this works'); }; Any ideas on what I am doing wrong here? Thanks for reading. Jannis

• WCF to WCF communication 401, HttpClient

  - by youwhut

  I have a WCF REST service that needs to communicate with another WCF REST service. There are three websites: Default Web Site Website1 Website2 If I set up both services in Default Web Site and connect to the other (using HttpClient) using the URI http://localhost/service then everything is okay. The desired set-up is to move these two services to separate websites and rather than using the URI http://localhost/service, accessing the service via http://website1.domain.com/service still using HttpClient. I received the exception: System.ArgumentOutOfRangeException: Unauthorized (401) is not one of the following: OK (200), Created (201), Accepted (202), NonAuthoritativeInformation (203), NoContent (204), ResetContent (205), PartialContent (206) I can see this is a 401, but what is going on here? Thanks

• jquery input-validation (number characters and decimal places).

  - by Cesar Lopez

  I have several javascript functions to validate the input data in textbox, so it will limit the user to type into the textbox a range of numbers (eg. from 0 to 500) an x amount of decimals (eg. 1 or 2 or 3 ....). I am having some issues with the javascript functions because they are three separate functions and the alerts get a bit mixed up. I was wondering if there is a jquery function that will make it neat, effective and simple. Thanks.

• Clear default values using onsubmit

  - by Thomas

  I need to clear the default values from input fields using js, but all of my attempts so far have failed to target and clear the fields. I was hoping to use onSubmit to excute a function to clear all default values (if the user has not changed them) before the form is submitted. <form method='get' class='custom_search widget custom_search_custom_fields__search' onSubmit='clearDefaults' action='http://www.example.com' > <input name='cs-Price-2' id='cs-Price-2' class='short_form' value='Min. Price' /> <input name='cs-Price-3' id='cs-Price-3' class='short_form' value='Max Price' /> <input type='submit' name='search' class='formbutton' value=''/> </form> How would you accomplish this?

• Getter/setter on javascript array?

  - by Martin Hansen

  Is there a way to get a get/set behaviour on an array? I imagine something like this: var arr = ['one', 'two', 'three']; var _arr = new Array(); for (var i=0; i < arr.length; i++) { arr[i].defineGetter('value', function(index) { //Do something return _arr[index]; }); arr[i].defineSetter('value', function(index, val) { //Do something _arr[index] = val; }); };

• Why does calling the YUI Datatable showCellEditor not display the editor?

  - by t-boy

  Clicking on the second cell (any row) in the datatable causes the cell editor to display. But, I am trying to display the cell editor from code. The code looks like the following: var firstEl = oDataTable.getFirstTdEl(rowIndex); var secondCell = oDataTable.getNextTdEl(firstEl); oDataTable.showCellEditor(secondCell); When I debug into the datatable.js code (either with a click or from the code above) it follows the same path through the showCellEditor function but the above code will not display the editor. I am using YUI version 2.8.0r4.

• Can't access web service when connected to the network :: HTTP 407

  - by Ian

  Hi All, I have a console application that communicates with a web service. Both of them are on the same machine. When I am accessing the web service with the LAN disabled, it connects without a problem. But if the LAN is enabled and connected to our office network, I receive this error: "HTTP 407 Proxy Authentication required - The ISA Server requires authorization to fulfill the request. Access to the Web Proxy service is denied." We've been hunting the source of the problem for three days now. We have tried everything that we can think of. Any ideas what's causing the problem? Additional notes: - The machine is in a Workgroup setup but with DNS suffix (computer.local). When accessing the web service, we type the address as "http://machine.computer.local/service.asmx" I talked to the IT guys and they said that we don't have an ISA server installed There is no "proxy" set in IE. The machine is in mint condition.

• How to recognize touch events and control a script object inside UIWebView?

  - by Markus S.

  Situation: I have an UIView with an UIWebView in it. When the viewDidLoad the Javascript Object inside the UIWebView is called (Microsoft Seadragon AJAX JS). For your Understanding: Seadragon loads a specified megapixel image(JPEG) and in a Desktop Browser like Firefox i can Zoom into the image and I can drag the crop for example from the middle to the left. In the iPhone Simulator (for iPad) only the Zooming Function is working on one single tap but when i try to drag the crop (with left mouse button click and holding it) I'm dragging the whole UIWebView but not the crop of course! Is that feature which the simulator isn't able to handle or what's yout solutin guys? Special Thanks!! P.S.: It's a bit jiggling when the zooming function of Seadragon is called. Is that authentic to the real performance of the iPad or does the simulator not have the power as the iPad has?

• InfoPath Repeating Group with Data from SharePoint and User Input

  - by 0x808080

  I have a series of questions which are pulled from a SharePoint list and loaded into a repeating section. The section has three elements, the Question # (from SharePoint), and Question itself (from SharePoint), and a drop down box Yes/No (NOT from SharePoint)... The repeating group portion works just fine, it is pulling all Question # and Questions from the SharePoint site, but I cannot bind the drop down box (yes/no) to any sort of local data source in order to record the information. Essentially what I have is a dynamically generated form which pulls questions off a SharePoint and a user will answer Yes or No for each question. I cannot associate the Yes/No drop down with anything because it resides within a Repeating section... Thanks for any help!

• Tricky compiler behavior

  - by Neeraj

  Simple java code snippet. It has three classes. After compiling the code please delete A.class and then execute the code. Code still runs, why its not checking whether the byte code of A exists or not? class A { static { System.out.println("In the class A"); } public A() { } } class B { private A a = null; static { System.out.println("In the class B"); } public B() { a = new A(); } } public class ExampleLinkage { static { System.out.println("In the class A"); } public ExampleLinkage(String str) { } public static void main(String args[]) { try { System.out.println("In the main method of ExampleLinkage"); Class.forName("com.bt.rtti.B"); } catch(Exception e) { e.printStackTrace(); } } }

• To subclass or not to subclass

  - by poulenc

  I have three objects; Action, Issue and Risk. These all contain a nunber of common variables/attributes (for example: Description, title, Due date, Raised by etc.) and some specific fields (risk has probability). The question is: Should I create 3 separate classes Action, Risk and Issue each containing the repeat fields. Create a parent class "Abstract_Item" containing these fields and operations on them and then have Action, Risk and Issue subclass Abstract_Item. This would adhere to DRY principal.

• Javascript top variable in IE8

  - by Jim Rootham

  I am trying to reference a javascript function in a .js file loaded in my main page from an iframe using the 'top' variable. It works in FF, Safari, and IE6 but not in IE8. The snippet is (assigned to onmouseover): top.set_image(this, 'images/login_h.png') Where set_image is my function. The error is "Object does not support this function" Also, I have been looking for the definition of top. I can't find it in the ECMAScript specification or the w3schools site and Google is unhelpful (who'da thunk top was a common word?).

• Problems with animateAlong in IE7

  - by Andrei

  Hi there, I'm having trouble making a simple shape move along a path in IE7 (the only version of IE I tried, actually). The following code works fine in chrome and firefox, but not IE. I couldn't find an obvious reason, has anybody seen something similar? canvas.path(rPath.path).attr("stroke", "blue"); var circle = canvas.circle(rPath.startX, rPath.startY, 5); circle.animateAlong(rPath.path, 3000, true); My rPath variable has the path and the starting point coordinates. Microsoft script debugger points to this line as the one where the code breaks: os.left != (t = x - left + "px") && (os.left = t); (line 2131 inside the uncompressed raphael.js script file, inside Element[proto].setBox = function (params, cx, cy) {...}) Any ideas? Any experience (good or bad) with raphael's animateAlong in IE7? TIA, Andrei

• C/C++/Assembly Programatically detect if hyper-threading is active on Windows, Mac and Linux

  - by HTASSCPP

  I can already correctly detect the number of logical processors correctly on all three of these platforms. To be able to detect the number of physical processors/cores correctly I'll have to detect if hyperthreading is supported AND active (or enabled if you prefer) and if so divide the number of logical processors by 2 to determine the number of physical processors. Perphaps I should provide an example: A quad core Intel CPU's with hyperthreading enabled has 4 physical cores, yet 8 logical processors (hyperthreading creates 4 more logical processors). So my current function would detect 8 instead of the desired 4. My question therefore is if there is a way to detect whether hyperthreading is supported AND ENABLED?

• which web services stacks are supported on JBoss AS 5?

  - by Marina

  Hi, I've been trying to find this info in JBoss docs/forums/WIKIs - but could not get a concise answer to this question: Which web services stacks are supported (or you can make work on) in JBoss 5? I have a huge legacy app using Axis 1 web services which is running fine on WLS9.2. Now I have to migrate it to JBoss 5 and I have to decide whether I can leave Axis1 web services as is (at least for the time being, to get the app working on JBoss at all), or if I have to upgrade web services to Axis 2 or CXF. So, given the three options, Axis 1, Axis 2 and CXF - what does support for them look like on JBoss 5? Any gotchas, pain points, words of wisdom from experience? :)

• Displaying the selected item differently in ComboBox

  - by David Brunelle

  I have a combo box in which I set up an ItemTemplate that looks something like this: <ComboBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Piece.NoPiece}" Width="50" /> <TextBlock Text="{Binding Piece.Description}" Width="170" /> <TextBlock Text="{Binding Piece.Categorie.NomCategorie}" /> </StackPanel> </DataTemplate> </ComboBox.ItemTemplate> As you can see, I got three columns that let the user see different piece of information. However, I would like the selected item in the combo to display only the second column. In other word, is there a way to have an ItemTemplate that displays items in a different manner when you scroll down versus when it's closed and you only see the selection?

• AS3 Font embedding problem in ComboBox on a loaded movie clip

  - by Arafat

  Hi all, I have three movie clips, say, LoaderMC, ChildMC1, and ChildMC2. ChildMC1 has TLFTextfields in it with embedded fonts. ChildMC2 has both TLFTextfields as well as combo boxes.(with embedded fonts) When I compile those movieclips separately, I can view the combo box texts without any problem. If I load the ChildMC1 and ChildMC2 into the LoaderMC, the texts doesn't appear at all on both TLFtextfields and Combo Boxes. I tried embedding the fonts in the LoaderMC, then, TLFTextfields was able to show the texts but still the ComboBoxes couldn't display the text. If I don't embed the fonts in the combo box, I can able to view the texts. What could be the problem? I read an article which says, "No one has completely understood the font embedding in flash AS3, we just have to do trial and error, to get it done" I don't know how far it is true, but in my case it seems, I should agree! Please help me...

• Why does calling glMatrixMode(GL_PROJECTION) give me EXC_BAD_ACCESS in an iPhone app?

  - by MrDatabase

  I have an iphone app where I call these three functions in appDidFinishLaunching: glMatrixMode(GL_PROJECTION); glOrthof(0, rect.size.width, 0, rect.size.height, -1, 1); glMatrixMode(GL_MODELVIEW); When stepping through with the debugger I get EXC BAD ACCESS when I execute the first line. Any ideas why this is happening? Btw I have another application where I do the same thing and it works fine. So I've tried to duplicate everything in that app (#imports, adding OpenGLES framework, etc) but now I'm just stuck.

• Recommended Visual Studio config for referencing an assembly created with ILMerge

  - by Daniel Schaffer

  I have a solution in Visual Studio with 5 projects. They are: Foo.Core: Core functionality Foo.Api: Generated code built on top of core Foo.Web: Web-specific extensions Foo.Web.Mvc: MVC-specific extensions Newtonsoft.Json: 3rd party library I want to use ILMerge to merge Foo.Core, Foo.Api and Newtonsoft.Json into a single assembly, called Foo. That's the easy part. The problem I'm running into is that Foo.Web and Foo.Web.Mvc both need to reference all three of the merged assemblies. If I reference the original assemblies, they will have invalid references after I do the ILMerge. If I reference the ILMerged assembly, I have to reference a debug assembly and then change it before I package everything up, which doesn't seem ideal. I've tried creating a project called Foo, which references the 3 merged assemblies and replaces its own output with the ILmerged assembly, but that doesn't seem to work at all. Is there a reliable way to do this?

• Is there any JavaScript Library to intelligently truncate strings?

  - by j0ker

  I need to truncate strings in a side menu to make the fit into a div without a linebreak. The divs have a fixed width. I'm looking for a library to do that for me. If a string is too long to fit into the div, it should be truncated like: <div>This string is too long</div> == <div>This string is...ong</div> As you can see, the string is not only truncated by an ellipsis but the last three letters are also visible. This is meant to increase readability. The truncation should not care about spaces. Does anyone know of a library that includes such functionality? We're mainly using jQuery throughout the project. Thanks in advance!
