• Hibernate: OutOfMemoryError persisting Blob when printing log message

  - by paul

  I have a Hibernate Entity: @Entity class Foo { //... @Lob public byte[] getBytes() { return bytes; } //.... } My VM is configured with a maximum heap size of 512 MB. When I try to persist an object which has a 75 MB large object, I get an OutOfMemoryError. The names of the methods in the stack trace (StringBuilder, ByteArrayBlobType.toLoggableString, pretty.Printer.toString) suggest that hibernate is trying to write a very large log message that contains my object. Am I correct about why hibernate is using so much memory? What is the simplest way to work around this problem? java.lang.OutOfMemoryError: Java heap space at java.lang.AbstractStringBuilder.<init>(AbstractStringBuilder.java:44) at java.lang.StringBuilder.<init>(StringBuilder.java:81) at org.hibernate.type.ByteArrayBlobType.toString(ByteArrayBlobType.java:117) at org.hibernate.type.ByteArrayBlobType.toLoggableString(ByteArrayBlobType.java:127) at org.hibernate.pretty.Printer.toString(Printer.java:53) at org.hibernate.pretty.Printer.toString(Printer.java:90) at org.hibernate.event.def.AbstractFlushingEventListener.flushEverythingToExecutions(AbstractFlushingEventListener.java:97) at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:26) at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1000) at org.jboss.seam.persistence.HibernateSessionProxy.flush(HibernateSessionProxy.java:181)

• model not showing up in django admin.

  - by Zayatzz

  Hi. I have ceated several django apps and stuffs for my own fund and so far everything has been working fine. Now i just created new project (django 1.2.1) and have run into trouble from 1st moments. I created new app - game and new model Game. i created admin.py and put related stuff into it. Ran syncdb and went to check into admin. Model did not show up there. I proceeded to check and doublecheck and read through previous similar threads: http://stackoverflow.com/questions/1839927/registered-models-do-not-show-up-in-admin http://stackoverflow.com/questions/1694259/django-app-not-showing-up-in-admin-interface But as far as i can tell, they dont help me either. Perhaps someone else can point this out for me. models.py in game app: # -*- coding: utf-8 -*- from django.db import models class Game(models.Model): type = models.IntegerField(blank=False, null=False, default=1) teamone = models.CharField(max_length=100, blank=False, null=False) teamtwo = models.CharField(max_length=100, blank=False, null=False) gametime = models.DateTimeField(blank=False, null=False) admin.py in game app: # -*- coding: utf-8 -*- from jalka.game.models import Game from django.contrib import admin class GameAdmin(admin.ModelAdmin): list_display = ['type', 'teamone', 'teamtwo', 'gametime'] admin.site.register(Game, GameAdmin) project settings.py: MIDDLEWARE_CLASSES = ( 'django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', ) ROOT_URLCONF = 'jalka.urls' TEMPLATE_DIRS = ( "/home/projects/jalka/templates/" ) INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.messages', 'django.contrib.admin', 'game', ) urls.py: from django.conf.urls.defaults import * # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', # Example: # (r'^jalka/', include('jalka.foo.urls')), (r'^admin/', include(admin.site.urls)), ) Alan.

• C# mvc2 client side form validation with xval, prevent post

  - by Rob

  I'm using xval to use client side validation in my asp.net mvc2 webapplication. Despite the errors it's giving when i enter text in a nummeric field it still tries to post the form to the database. The incorrect values are being replaced by 0 and saved to the database. But instead it shouldn't even be possible to try and submit the form. Can anyone help me out here? I've set the attributes as below; [Property] [ShowColumnInCrud(true, label = "FromPriceInCents")] [Required] //[Range(1, Int32.MaxValue)] public virtual Int32 FromPriceInCents{ get; set; } The controller catching the request looks as below; I'm getting no errors in this part. [AcceptVerbs(HttpVerbs.Post)] [Transaction] [ValidateInput(false)] public override ActionResult Create() { //some foo happens } My view looks like below; <div class="label"><label for="Price">FromPrice</label></div> <div class="field"> <%= Html.TextBox("FromPriceInCents")%> <%= Html.ValidationMessage("product.FromPriceInCents")%></div> And at the end of the view i have the following rule which in html code generates the correct validation rules <%= Html.ClientSideValidation<Product>("Product") %> I hope someone can helps me out with this issue, thanks in advance!

• Finding duplicate rows in SQL Server

  - by xtine

  I have a SQL Server database of organizations, and there are many duplicate rows. I want to run a select statement to grab all of these and the amount of dupes, but also return the ids that are associated with each organization. A statement like: SELECT orgName, COUNT(*) AS dupes FROM organizations GROUP BY orgName HAVING (COUNT(*) > 1) Will return something like orgName | dupes ABC Corp | 7 Foo Federation | 5 Widget Company | 2 But I'd also like to grab the IDs of them. Is there any way to do this? Maybe like a orgName | dupeCount | id ABC Corp | 1 | 34 ABC Corp | 2 | 5 ... Widget Company | 1 | 10 Widget Company | 2 | 2 The reason being that there is also a separate table of users that link to these organizations, and I would like to unify them (therefore remove dupes so the users link to the same organization instead of dupe orgs). But I would like part manually so I don't screw anything up, but I would still need a statement returning the IDs of all the dupe orgs so I can go through the list of users. Any help would be greatly appreciated. Thanks :)

• docs/examples on libxml2 type system?

  - by Wang

  I'm reading through the libxml2 API and examples on xmlsoft.com and having some real difficulty wrapping my head around the type system. For example, the _xmlAttribute struct has an xmlChar* field called name. This obviously refers to the name of the attribute (e.g., "bar" for the struct tied to the element <foo bar='baz' />). The _xmlAttribute struct also has a field called value, which I would expect to be "baz", except the type is xmlNodePtr. Um, what? I guess I could write up some test code and examine the memory in gdb, but there has to be an easier way. Has anyone written up examples of the data structures generated by a libxml2 parser? I'm looking for an English prose text, not generated documentation, that will walk me through the various types and the values they take when parsing some example bit of XML. Bonus points if it presents only the subset of libxml2 needed to read and write a config file---no namespaces or XPath or even modifying an existing document, just parse some XML, access the data, and then write it out again.

• Median Filter a bi-level image with JAI

  - by Mark

  I'd like to apply a Median Filter to a bi-level image and output a bi-level image. The JAI median filter seems to output an RGB image, which I'm having trouble downconverting back to bi-level. Currently I can't even get the image back into gray color-space, my code looks like this: BufferedImage src; // contains a bi-level image ParameterBlock pb = new ParameterBlock(); pb.addSource(src); pb.add(MedianFilterDescriptor.MEDIAN_MASK_SQUARE); pb.add(3); RenderedOp result = JAI.create("MedianFilter", pb); ParameterBlock pb2 = new ParameterBlock(); pb2.addSource(result); pb2.add(new double[][]{{0.33, 0.34, 0.33, 0}}); RenderedOp grayResult = JAI.create("BandCombine", pb2); BufferedImage foo = grayResult.getAsBufferedImage(); This code hangs on the grayResult line and appears not to return. I assume that I'll eventually need to call the "Binarize" operation in JAI. Edit: Actually, the code appears to be stalling once I call getAsBufferedImage(), but returns nearly instantly when the second operation ("BandCombine") is removed. Is there a better way to keep the Median Filtering in the source color domain? If not, how do I downconvert back to binary?

• Twitter Bootstrap 3 top nav dropdown covered by subnav bar

  - by Aaron Qian

  I'm creating a Twitter Bootstrap main nav and sub nav with a drop down menu on the main nav. The problem is that I can never get the drop down menu to be shown above the sub nav. Here is the HTML: <div class="mainnav navbar navbar-fixed-top navbar-inverse"> <div class="navbar-inner"> <div class="container"> <ul class="nav"> <li class="dropdown"> <a href="#" class="dropdown-toggle" data-toggle="dropdown"> Settings </a> <ul class="dropdown-menu"> <li><a>test 1</a></li> <li><a>test 2</a></li> </ul> </li> </ul> </div> </div> </div> <div class="subnav navbar navbar-fixed-top"> <div class="navbar-inner"> <div class="container"> <ul class="nav"> <li><a>foo</a></li> <li><a>bar</a></li> </ul> </div> </div> </div> CSS: .subnav { top: 40px; } .mainnav .dropdown-menu { // how can I show this menu above the subnav??? }

• Validation using JAXB and Stax to marshal XML document

  - by bajafresh4life

  I have created an XML schema (foo.xsd) and used xjc to create my binding classes for JAXB. Let's say the root element is "collection" and I am writing N "document" objects, which are complex types. Because I plan to write out large XML files, I am using Stax to write out the "collection" root element, and JAXB to marshal document subtrees using Marshaller.marshal(JAXBElement, XMLEventWriter). This is the approach recommended by jaxb's unofficial user's guide: https://jaxb.dev.java.net/guide/Different_ways_of_marshalling.html#Marshalling_into_a_subtree My question is, how can I validate the XML while it's being marshalled? If I bind a schema to the JAXB marshaller (using Marshaller.setSchema()), I get validation errors because I am only marshalling a subtree (it's complaining that it's not seeing the "collection" root element"). I suppose what I really want to do is bind a schema to the Stax XMLEventWriter or something like that. Any comments on this overall approach would be helpful. Basically I want to be able to use JAXB to marshal and unmarshal large XML documents without running out of memory, so if there's a better way to do this let me know.

• Parallel WCF calls to multiple servers

  - by gregmac

  I have a WCF service (the same one) running on multiple servers, and I'd like to call all instances in parallel from a single client. I'm using ChannelFactory and the interface (contract) to call the service. Each service has a local <endpoint> client defined in the .config file. What I'm trying to do is build some kind of generic framework to avoid code duplication. For example a synchronous call in a single thread looks something like this: Dim remoteName As String = "endpointName1" Dim svcProxy As ChannelFactory(Of IMyService) = New ChannelFactory(Of IMyService)(remoteName) Try svcProxy.Open() Dim svc As IMyService = svcProxy.CreateChannel() nodeResult = svc.TestRemote("foo") Finally svcProxy.Close() End Try The part I'm having difficulty with is how to specify and actually invoke the actual remote method (eg "TestRemote") without having to duplicate the above code, and all the thread-related stuff that invokes that, for each method. In the end, I'd like to be able to write code along the lines of (consider this psuedo code): Dim results as Dictionary(Of Node, ExpectedReturnType) results = ParallelInvoke(IMyService.SomeMethod, parameter1, parameter2) where ParallelInvoke() will take the method as an argument, as well as the parameters (paramArray or object() .. whatever) and then go run the request on each remote node, block until they all return an answer or timeout, and then return the results into a Dictionary with the key as the node, and the value as whatever value it returned. I can then (depending on the method) pick out the single value I need, or aggregate all the values from each server together, etc. I'm pretty sure I can do this using reflection and InvokeMember(), but that requires passing the method as a string (which can lead to errors like calling a non-existing method that can't be caught at compile time), so I'd like to see if there is a cleaner way to do this. Thanks

• Change namespace Prefix WCF Envelope

  - by activebiz

  I was wondering is there anyway to change the namespace prefix for the WCF SOAP request? As you can see in the example below, The Envelope has namespace "http://www.w3.org/2005/08/addressing" with prefix 'a'. I want to change this to 'foo'. How can I do that. Note I dont have control over service code I can only create proxy class from the WSDL . <s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://schemas.xmlsoap.org/soap/envelope/"> <s:Header> <a:Action s:mustUnderstand="1">http://www.starstandards.org/webservices/2005/10/transport/operations/MyAction</a:Action> <h:payloadManifest xmlns="http://www.starstandards.org/webservices/2005/10/transport" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:h="http://www.starstandards.org/webservices/2005/10/transport"> <manifest contentID="Content0" namespaceURI="http://www.starstandard.org/STAR/5" element="TESTMETHOD" version="5.2.4"></manifest> </h:payloadManifest> <h:Identity xmlns="urn:xxx/xxx/" xmlns:h="urn:xxx/xxx"> <SiteCode>XXXXXX</SiteCode> </h:Identity> <a:To>urn:xxx/xxx/Method1</a:To> <MessageID xmlns="http://www.w3.org/2005/08/addressing">XXXXX</MessageID> <a:ReplyTo> <a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address> </a:ReplyTo> </s:Header> Many thanks

• How do I remove accents from characters in a PHP string?

  - by georgebrock

  I'm attempting to remove accents from characters in PHP string as the first step to making the string usable in a URL. I'm using the following code: $input = "Fóø Bår"; setlocale(LC_ALL, "en_US.utf8"); $output = iconv("utf-8", "ascii//TRANSLIT", $input); print($output); The output I would expect would be something like this: F'oo Bar However, instead of the accented characters being transliterated they are replaced with question marks: F?? B?r Everything I can find online indicates that setting the locale will fix this problem, however I'm already doing this. I've already checked the following details: The locale I am setting is supported by the server (included in the list produced by locale -a) The source and target encodings (UTF-8 and ASCII) are supported by the server's version of iconv (included in the list produced by iconv -l) The input string is UTF-8 encoded (verified using PHP's mb_check_encoding function, as suggested in the answer by mercator) The call to setlocale is successful (it returns 'en_US.utf8' rather than FALSE) The cause of the problem: The server is using the wrong implementation of iconv. It has the glibc version instead of the required libiconv version. Note that the iconv function on some systems may not work as you expect. In such case, it'd be a good idea to install the GNU libiconv library. It will most likely end up with more consistent results. – PHP manual's introduction to iconv Details about the iconv implementation that is used by PHP are included in the output of the phpinfo function. (I'm not able to re-compile PHP with the correct iconv library on the server I'm working with for this project so the answer I've accepted below is the one that was most useful for removing accents without iconv support.)

• VS Solution and Mercurial repository layout for a c# project with plugins and external libraries.

  - by Joviee

  I'm developing a project in .NET (using C# to be more specific). Using Visual Studio as an IDE. Using Mercurial for version control. I'll be using some third-party libraries: ThirdParty.Foo.dll ThirdParty.Bar.dll ThirdParty.Baz.dll And some in-house libraries: Company.A Company.B Company.C Company.D (References third party libraries) Company.E (References Company.A) The project itself will have the following components: Project.Core Project.DataModel (references in-house/third-party libraries) Project.GUI (references Core, DataModel, and in-house/third-party libraries) Project.PluginOne (references Core, DataModel, and in-house/third-party libraries) Project.PluginTwo (references Core, DataModel, and in-house/third-party libraries) * can be an arbitrary number of plugins * I'm quite new to Mercurial, so I don't really know the best way to structure my repositories for a project like this, with a lot of interconnected components. The in-house libraries are fairly distinct, so I would say that each one of them should have its own repository. However, some of them use functionality provided by others. How should these dependencies be managed? The project plug-ins should be distinct from eachother, so I'd imagine that each would have its own repository. How should the dependencies on the in-house/third-party libraries and the rest of the project (Project.DataModel and Project.Core) be managed, with regards to the solution layout and the repository layout? So basically, for a project like this, what are the best way of structuring: (a) my visual studio solutions (b) my source control repository/repositories

• Simulating aspects of static-typing in a duck-typed language

  - by Mike

  In my current job I'm building a suite of Perl scripts that depend heavily on objects. (using Perl's bless() on a Hash to get as close to OO as possible) Now, for lack of a better way of putting this, most programmers at my company aren't very smart. Worse, they don't like reading documentation and seem to have a problem understanding other people's code. Cowboy coding is the game here. Whenever they encounter a problem and try to fix it, they come up with a horrendous solution that actually solves nothing and usually makes it worse. This results in me, frankly, not trusting them with code written in duck typed language. As an example, I see too many problems with them not getting an explicit error for misusing objects. For instance, if type A has member foo, and they do something like, instance->goo, they aren't going to see the problem immediately. It will return a null/undefined value, and they will probably waste an hour finding the cause. Then end up changing something else because they didn't properly identify the original problem. So I'm brainstorming for a way to keep my scripting language (its rapid development is an advantage) but give an explicit error message when an an object isn't used properly. I realize that since there isn't a compile stage or static typing, the error will have to be at run time. I'm fine with this, so long as the user gets a very explicit notice saying "this object doesn't have X" As part of my solution, I don't want it to be required that they check if a method/variable exists before trying to use it. Even though my work is in Perl, I think this can be language agnostic.

• Delegates in .NET: how are they constructed ?

  - by Saulius

  While inspecting delegates in C# and .NET in general, I noticed some interesting facts: Creating a delegate in C# creates a class derived from MulticastDelegate with a constructor: .method public hidebysig specialname rtspecialname instance void .ctor(object 'object', native int 'method') runtime managed { } Meaning that it expects the instance and a pointer to the method. Yet the syntax of constructing a delegate in C# suggests that it has a constructor new MyDelegate(int () target) where I can recognise int () as a function instance (int *target() would be a function pointer in C++). So obviously the C# compiler picks out the correct method from the method group defined by the function name and constructs the delegate. So the first question would be, where does the C# compiler (or Visual Studio, to be precise) pick this constructor signature from ? I did not notice any special attributes or something that would make a distinction. Is this some sort of compiler/visualstudio magic ? If not, is the T (args) target construction valid in C# ? I did not manage to get anything with it to compile, e.g.: int () target = MyMethod; is invalid, so is doing anything with MyMetod, e.g. calling .ToString() on it (well this does make some sense, since that is technically a method group, but I imagine it should be possible to explicitly pick out a method by casting, e.g. (int())MyFunction. So is all of this purely compiler magic ? Looking at the construction through reflector reveals yet another syntax: Func CS$1$0000 = new Func(null, (IntPtr) Foo); This is consistent with the disassembled constructor signature, yet this does not compile! One final interesting note is that the classes Delegate and MulticastDelegate have yet another sets of constructors: .method family hidebysig specialname rtspecialname instance void .ctor(class System.Type target, string 'method') cil managed Where does the transition from an instance and method pointer to a type and a string method name occur ? Can this be explained by the runtime managed keywords in the custom delegate constructor signature, i.e. does the runtime do it's job here ?

• Ascii Bytes Array To Int32 or Double

  - by Michael Covelli

  I'm re-writing alibrary with a mandate to make it totally allocation free. The goal is to have 0 collections after the app's startup phase is done. Previously, there were a lot of calls like this: Int32 foo = Int32.Parse(ASCIIEncoding.ASCII.GetString(bytes, start, length)); Which I believe is allocating a string. I couldn't find a C# library function that would do the same thing automatically. I looked at the BitConverter class, but it looks like that is only if your Int32 is encoded with the actual bytes that represent it. Here, I have an array of bytes representing Ascii characters that represent an Int32. Here's what I did public static Int32 AsciiBytesToInt32(byte[] bytes, int start, int length) { Int32 Temp = 0; Int32 Result = 0; Int32 j = 1; for (int i = start + length - 1; i >= start; i--) { Temp = ((Int32)bytes[i]) - 48; if (Temp < 0 || Temp > 9) { throw new Exception("Bytes In AsciiBytesToInt32 Are Not An Int32"); } Result += Temp * j; j *= 10; } return Result; } Does anyone know of a C# library function that already does this in a more optimal way? Or an improvement to make the above run faster (its going to be called millions of times during the day probably). Thanks!

• Mapping a child collection without indexing based on database primary key or using bag

  - by Colin Bowern

  I have a existing parent-child relationship I am trying to map in Fluent Nhibernate: [RatingCollection] -- [Rating] Rating Collection has: ID (database generated ID) Code Name Rating has: ID (database generated id) Rating Collection ID Code Name I have been trying to figure out which permutation of HasMany makes sense here. What I have right now: HasMany<Rating>(x => x.Ratings) .WithTableName("Rating") .KeyColumnNames.Add("RatingCollectionId") .Component(c => { c.Map(x => x.Code); c.Map(x => x.Name); ); It works from a CRUD perspective but because it's a bag it ends up deleting the rating contents any time I try to do a simple update / insert to the Ratings property. What I want is an indexed collection but not using the database generated ID (which is in the six digit range right now). Any thoughts on how I could get a zero-based indexed collection (so I can go entity.Ratings[0].Name = "foo") which would allow me to modify the collection without deleting/reinserting it all when persisting?

• SDL_image/C++ OpenGL Program: IMG_Load() produces fuzzy images

  - by Kami

  I'm trying to load an image file and use it as a texture for a cube. I'm using SDL_image to do that. I used this image because I've found it in various file formats (tga, tif, jpg, png, bmp) The code : SDL_Surface * texture; //load an image to an SDL surface (i.e. a buffer) texture = IMG_Load("/Users/Foo/Code/xcode/test/lena.bmp"); if(texture == NULL){ printf("bad image\n"); exit(1); } //create an OpenGL texture object glGenTextures(1, &textureObjOpenGLlogo); //select the texture object you need glBindTexture(GL_TEXTURE_2D, textureObjOpenGLlogo); //define the parameters of that texture object //how the texture should wrap in s direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT); //how the texture should wrap in t direction glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT); //how the texture lookup should be interpolated when the face is smaller than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); //how the texture lookup should be interpolated when the face is bigger than the texture glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR); //send the texture image to the graphic card glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, texture->w, texture->h, 0, GL_RGB, GL_UNSIGNED_BYTE, texture-> pixels); //clean the SDL surface SDL_FreeSurface(texture); The code compiles without errors or warnings ! I've tired all the files formats but this always produces that ugly result : I'm using : SDL_image 1.2.9 & SDL 1.2.14 with XCode 3.2 under 10.6.2 Does anyone knows how to fix this ?

• Background image in a JFrame.

  - by thepandaatemyface

  Hi, This question has been asked a lot but everywhere the answers fall short. I can get a JFrame to display a background image just fine by extending JPanel and overriding paintComponent, like so: class BackgroundPanel extends JPanel { private ImageIcon imageIcon; public BackgroundPanel() { this.imageIcon = Icons.getIcon("foo"); } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); g.drawImage(imageIcon.getImage(), 0,0,imageIcon.getIconWidth(),imageIcon.getIconHeight(),this); } } But now, how do you add a component on top of that background? When I go JFrame w = new JFrame() ; Container cp = w.getContentPane(); cp.setLayout(null); BackgroundPanel bg = new BackgroundPanel(); cp.add(bg); JPanel b = new JPanel(); b.setSize(new Dimension(30, 40)); b.setBackground(Color.red); cp.add(b); w.pack() w.setVisible(true) It shows the little red square (or any other component) and not the background, but when I remove cp.setLayout(null);, the background shows up but not my other component. I'm guessing this has something to do with the paintComponent not being called by the null LayoutManager, but I'm not at all familiar with how LayoutManagers work (this is a project for college and the assignment specifically says not to use a LayoutManager) When i make the image the background has to display null (and so, transparant (??)) the red square shows up so it might be that the background is actually above my other components) Does anyone anyone have any ideas? Thanks

• Evaluation of environment variables in command run by Java's Runtime.exec()

  - by Tom Duckering

  Hi, I have a scenarios where I have a Java "agent" that runs on a couple of platforms (specifically Windows, Solaris & AIX). I'd like to factor out the differences in filesystem structure by using environment variables in the command line I execute. As far as I can tell there is no way to get the Runtime.exec() method to resolve/evaluate any environment variables referenced in the command String (or array of Strings). I know that if push comes to shove I can write some code to pre-process the command String(s) and resolve enviroment variables by hand (using getEnv() etc). However I'm wondering if there is a smarter way to do this since I'm sure I'm not the only person wanting to do this and I'm sure there are pitfalls in "knocking up" my own implementation. Your guidance and suggestions are most welcome. edit: I would like to refer to environment variables in the command string using some consistent notation such as $VAR and/or %VAR%. Not fussed which. edit: To be clear I'd like to be able to execute a command such as: perl $SCRIPT_ROOT/somePerlScript.pl args on Windows and Unix hosts using Runtime.exec(). I specify the command in config file that describes a list of jobs to run and it has to be able to work cross platform, hence my thought that an environment variable would be useful to factor out the filesystem differences (/home/username/scripts vs C:\foo\scripts). Hope that helps clarify it. Thanks. Tom

• Regex to remove conditional comments

  - by cnu

  I want a regex which can match conditional comments in a HTML source page so I can remove only those. I want to preserve the regular comments. I would also like to avoid using the .*? notation if possible. The text is foo <!--[if IE]> <style type="text/css"> ul.menu ul li{ font-size: 10px; font-weight:normal; padding-top:0px; } </style> <![endif]--> bar and I want to remove everything in <!--[if IE]> and <![endif]--> EDIT: It is because of BeautifulSoup I want to remove these tags. BeautifulSoup fails to parse and gives an incomplete source EDIT2: [if IE] isn't the only condition. There are lots more and I don't have any list of all possible combinations. EDIT3: Vinko Vrsalovic's solution works, but the actual problem why beautifulsoup failed was because of a rogue comment within the conditional comment. Like <!--[if lt IE 7.]> <script defer type="text/javascript" src="pngfix_253168.js"></script><!--png fix for IE--> <![endif]--> Notice the <!--png fix for IE--> comment? Though my problem was solve, I would love to get a regex solution for this.

• Get the accordion style for non-accordion elements

  - by SK.

  Hi, I am completely new in jQuery UI's CSS styles so please bear with me. I have to make a list of contact people. <div id="accordion"> <h3><a href="#">George Foo</a></h3> <div> some information </div> <h3><a href="#">Michelle Bar</a></h3> <div> some information </div> <h3><a href="#">Bill Wind</a></h3> <div> some information </div> </div> At first, I thought using the accordion style. However, usage showed me that opening more than one contact might be interesting as well. So I read the note on the bottom of the accordion page to use this instead of accordion: From page: jQuery(document).ready(function(){ $('.accordion .head').click(function() { $(this).next().toggle('slow'); return false; }).next().hide(); }); My problem is that it doesn't look like accordion (smoothness style). I suppose I am not putting the accordion and head class at the right place, but as of now the names look like default links. How can I have the same look for the headers as the accordion effect, without using accordion? I tried searching around but from what I found that specific problem is not much discussed. Thanks.

• Add incremental numbers at the end of a string in a loop in Javascript.

  - by Kyle Sevenoaks

  This Javascript is part of a Foreach loop. var stickytooltip={ tooltipoffsets: [20, -30], //additional x and y offset from mouse cursor for tooltips fadeinspeed: 200, //duration of fade effect in milliseconds rightclickstick: false, //sticky tooltip when user right clicks over the triggering element (apart from pressing "s" key) ? stickybordercolors: ["#0a5692", "#0a5692"], //border color of tooltip depending on sticky state stickynotice: ["Press \"s\"", "or right click", "to sticky box"], //customize tooltip status message stickynotice2: "Click outside this box to hide it", //customize tooltip status message //***** NO NEED TO EDIT BEYOND HERE isdocked: false, positiontooltip:function($, $tooltip, e){ var x=e.pageX+this.tooltipoffsets[0], y=e.pageY+this.tooltipoffsets[1] var tipw=$tooltip.outerWidth(), tiph=$tooltip.outerHeight(), x=(x+tipw>$(document).scrollLeft()+$(window).width())? x-tipw-(stickytooltip.tooltipoffsets[0]*2) : x y=(y+tiph>$(document).scrollTop()+$(window).height())? $(document).scrollTop()+$(window).height()-tiph-10 : y $tooltip.css({left:x, top:y}) }, showbox:function($, $tooltip, e){ $tooltip.fadeIn(this.fadeinspeed) this.positiontooltip($, $tooltip, e) }, hidebox:function($, $tooltip){ if (!this.isdocked){ $tooltip.stop(false, true).hide() $tooltip.css({borderColor:'black'}).find('.stickystatus:eq(0)').css({background:this.stickybordercolors[0]}).html(this.stickynotice) } }, docktooltip:function($, $tooltip, e){ this.isdocked=true $tooltip.css({borderColor:'darkred'}).find('.stickystatus:eq(0)').css({background:this.stickybordercolors[1]}).html(this.stickynotice) }, init:function(targetselector, tipid){ jQuery(document).ready(function($){ var $targets=$(targetselector) var $tooltip=$('#'+tipid).appendTo(document.body) if ($targets.length==0) return var $alltips=$tooltip.find('div.atip') if (!stickytooltip.rightclickstick) stickytooltip.stickynotice[1]='' stickytooltip.stickynotice=stickytooltip.stickynotice.join(' ') stickytooltip.hidebox($, $tooltip) $targets.bind('mouseenter', function(e){ $alltips.hide().filter('#'+$(this).attr('data-tooltip')).show() stickytooltip.showbox($, $tooltip, e) }) $targets.bind('mouseleave', function(e){ stickytooltip.hidebox($, $tooltip) }) $targets.bind('mousemove', function(e){ if (!stickytooltip.isdocked){ stickytooltip.positiontooltip($, $tooltip, e) } }) $tooltip.bind("mouseenter", function(){ stickytooltip.hidebox($, $tooltip) }) $tooltip.bind("click", function(e){ e.stopPropagation() }) $(this).bind("click", function(e){ if (e.button==0){ stickytooltip.isdocked=false stickytooltip.hidebox($, $tooltip) } }) $(this).bind("contextmenu", function(e){ if (stickytooltip.rightclickstick && $(e.target).parents().andSelf().filter(targetselector).length==1){ //if oncontextmenu over a target element stickytooltip.docktooltip($, $tooltip, e) return false } }) $(this).bind('keypress', function(e){ var keyunicode=e.charCode || e.keyCode if (keyunicode==115){ //if "s" key was pressed stickytooltip.docktooltip($, $tooltip, e) } }) }) //end dom ready } } //stickytooltip.init("targetElementSelector", "tooltipcontainer") stickytooltip.init("*[data-tooltip]", "mystickytooltip") I need to just add some code to the end of "mystickytooltip" to add 1, 2, 3, 4 each time it loops. My JS-foo is nonexistant, please help :)

• Using {% url ??? %} in django templates

  - by user563247

  I have looked a lot on google for answers of how to use the 'url' tag in templates only to find many responses saying 'You just insert it into your template and point it at the view you want the url for'. Well no joy for me :( I have tried every permutation possible and have resorted to posting here as a last resort. So here it is. My urls.py looks like this: from django.conf.urls.defaults import * from login.views import * from mainapp.views import * import settings # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', # Example: # (r'^weclaim/', include('weclaim.foo.urls')), (r'^login/', login_view), (r'^logout/', logout_view), ('^$', main_view), # Uncomment the admin/doc line below and add 'django.contrib.admindocs' # to INSTALLED_APPS to enable admin documentation: # (r'^admin/doc/', include('django.contrib.admindocs.urls')), # Uncomment the next line to enable the admin: (r'^admin/', include(admin.site.urls)), #(r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': '/home/arthur/Software/django/weclaim/templates/static'}), (r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}), ) My 'views.py' in my 'login' directory looks like: from django.shortcuts import render_to_response, redirect from django.template import RequestContext from django.contrib import auth def login_view(request): if request.method == 'POST': uname = request.POST.get('username', '') psword = request.POST.get('password', '') user = auth.authenticate(username=uname, password=psword) # if the user logs in and is active if user is not None and user.is_active: auth.login(request, user) return render_to_response('main/main.html', {}, context_instance=RequestContext(request)) #return redirect(main_view) else: return render_to_response('loginpage.html', {'box_width': '402', 'login_failed': '1',}, context_instance=RequestContext(request)) else: return render_to_response('loginpage.html', {'box_width': '400',}, context_instance=RequestContext(request)) def logout_view(request): auth.logout(request) return render_to_response('loginpage.html', {'box_width': '402', 'logged_out': '1',}, context_instance=RequestContext(request)) and finally the main.html to which the login_view points looks like: <html> <body> test! <a href="{% url logout_view %}">logout</a> </body> </html> So why do I get 'NoReverseMatch' every time? *(on a slightly different note I had to use 'context_instance=RequestContext(request)' at the end of all my render-to-response's because otherwise it would not recognise {{ MEDIA_URL }} in my templates and I couldn't reference any css or js files. I'm not to sure why this is. Doesn't seem right to me)*
