  • Completely bizarre Firefox CSS bug

    - by Jason
    I've been doing front end development for a long time, and I have NEVER come across a bug like this before... Save the following HTML to a file and view it in Firefox (mine is 3.6.3): <html xmlns="http://www.w3.org/1999/xhtml"> <head> <style type="text/css"> body { font-family: Helvetica, Sans-Serif;} h2 {font-weight: normal;} </style> </head> <body> <h2>Some normal text <strong>some bold text</strong> weird huh?</h2> </body> </html> If you don't want to give it a shot the output is like your cat walked across your keyboard while character map was turned on, except in the strong tags. I feel like this may be a font issue? When I get rid of font-weight: normal it goes back to normal, but I don't want everything to be bolded in my h2... Anyone have any ideas? More importantly, is anyone able to reproduce this?? Thanks.

  • How to Use XSLT to Replace Coordinate Separator With List of Tuples?

    - by kuloch
    I have a space-separated list of coordinate tuples. Each tuple consists of a space-separated list of 2-dimensional coordinates. E.g. "1.1 2.8 1.2 2.9" represents a line from POINT(1.1 2.8) to POINT(1.2 2.9). I need this to instead be "1.1,2.8 1.2,2.9". How would I use XSLT to perform the replacement of space-to-comma between pairs of numbers? I have the "string(gml:LinearRing/gml:posList)". This is being used on a Java Web Service that spits out GML 3.1.1 features with geometries. The service supports optional KML output, by using XSLT to transform the GML document into a KML document (at least, the chunks deemed "important"). I am locked into XSLT 1.0, so regex from XSLT 2.0 is not an option. I am aware that GML uses lat/lon while KML uses lon/lat. That's being handled before XSLT, though it would be nice to have that also done with XSLT.

  • [Python] name 'OptionGroup' is not defined

    - by Cawas
    Ok, so I made this rookie mistake below, but in my defense I was led to it thanks to how the help about this subject is on python docs, which states how to use optparse. It is actually an error under the gigantic tutorial section. In contrast and to my offense, I may be one of the very few stupid people who can't read very well and pay close attention on what I do. But since this took me so long to discover, I wanted to "document" it here: Python 2.6.1 (r261:67515, Feb 11 2010, 00:51:29) >>> from optparse import OptionParser >>> outputGroup = OptionGroup(parser, 'Output handling') Traceback (most recent call last): File "<stdin>", line 1, in <module> NameError: name 'OptionGroup' is not defined This is strictly done with examples found on the docs, and you can't find anything about it anywhere, be it that long long docs page, google or stackoverflow. Plus, reading optparse.py shows OptionGroup is there, so that adds to the confusion. I bet it will take less than 1 minute for someone to spot my error. For that I'll only add proper tags and / or modify the title later on. :)

  • SharePoint Designer Workflow: Unruly 'Collect User Data' Action

    - by Jeremy
    I'm a student in a SharePoint class online. This problem has riddled everyone I've discussed it with, including the teacher. There seems to be some sort of problem when I create a workflow with the collect data action. I can create workflows that send e-mails and use the other actions just fine. What could be causing this problem? My reproduction steps are simple: Create a new Site Collection with the Blank Site template. Create a new Custom List. In SharePoint Designer, start a new workflow on the Custom List. Add the collect data action to the workflow. Set the user to the one that created the task. Set the data to anything. A single check box, a string, Choice, doesn't matter. Leave the output variable as default. Mystery error appears! When the Check Workflow button is pressed, nothing happens. No message box appears at all. The warning icon in the Steps panel merely points out that there are some errors, it isn't specific as to what they are. Additionally, when I click on the data object again after it's been created, it doesn't populate the form with the old values. It goes back to the default name with no fields. So there's definitely something going wrong here. I've narrowed the problem down to the data object, but I don't know what to do about it. The workflow acts like normal for other activities. For example, delete the Collect Data action and add a Send Email one instead and it compiles and runs successfully.

  • How can I remove certain characters from inside angle-brackets, leaving the characters outside alone

    - by Iain Fraser
    Edit: To be clear, please understand that I am not using Regex to parse the html, that's crazy talk! I'm simply wanting to clean up a messy string of html so it will parse Edit #2: I should also point out that the control character I'm using is a special unicode character - it's not something that would ever be used in a proper tag under any normal circumstances Suppose I have a string of html that contains a bunch of control characters and I want to remove the control characters from inside tags only, leaving the characters outside the tags alone. For example Here the control character is the numeral "1". Input The quick 1<strong>orange</strong> lemming <sp11a1n 1class1='jumpe111r'11>jumps over</span> 1the idle 1frog Desired Output The quick 1<strong>orange</strong> lemming <span class='jumper'>jumps over</span> 1the idle 1frog So far I can match tags which contain the control character but I can't remove them in one regex. I guess I could perform another regex on my matches, but I'd really like to know if there's a better way. My regex Bear in mind this one only matches tags which contain the control character. <(([^>])*?`([^>])*?)*?> Thanks very much for your time and consideration. Iain Fraser

  • C++ Returning a Reference

    - by Devil Jin
    Consider the following code where I am returning double& and a string&. The thing works fine in the case of a double but not in the case of a string. Why is this difference in the behavior? In both the cases compiler does not even throws the Warning: returning address of local variable or temporary as I am returning a reference. #include <iostream> #include <string> using namespace std; double &getDouble(){ double h = 46.5; double &hours = h; return hours; } string &getString(){ string str = "Devil Jin"; string &refStr = str; return refStr; } int main(){ double d = getDouble(); cout << "Double = " << d << endl; string str = getString(); cout << "String = " << str.c_str() << endl; return 0; } Output: $ ./a.exe Double = 46.5 String =

  • db:migrate creates sequences but doesn't alter table?

    - by RewbieNewbie
    Hello, I have a migration that creates a postres sequence for auto incrementing a primary identifier, and then executes a statement for altering the column and specifying the default value: execute 'CREATE SEQUENCE "ServiceAvailability_ID_seq";' execute <<-SQL ALTER TABLE "ServiceAvailability" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceAvailability_ID_seq'); SQL If I run db:migrate everything seems to work, in that no errors are returned, however, if I run the rails application I get: Mnull value in column "ID" violates not-null constraint I have discovered by executing the sql statement in the migration manually, that this error is because the alter statement isn't working, or isn't being executed. If I manually execute the following statement: CREATE SEQUENCE "ServiceAvailability_ID_seq; I get: error : ERROR: relation "serviceavailability_id_seq" already exists Which means the migration successfully created the sequence! However, if I manually run: ALTER TABLE "ServiceProvider" ALTER COLUMN "ID" set DEFAULT NEXTVAL('ServiceProvider_ID_seq'); SQL It runs successfully and creates the default NEXTVAL. So the question is, why is the migration file creating the sequence with the first execute statement, but not altering the table in the second execute? (Remembering, no errors are output on running db:migrate) Thank you and apologies for tl:dr

  • Java : HTTP POST Request

    I have to do a http post request to a web-service for authenticating the user with username and password. The Web-service guy gave me following information to construct HTTP Post request.

  • Static variable for communication among like-typed objects

    - by Dan Ray
    I have a method that asynchronously downloads images. If the images are related to an array of objects (a common use-case in the app I'm building), I want to cache them. The idea is, I pass in an index number (based on the indexPath.row of the table I'm making by way through), and I stash the image in a static NSMutableArray, keyed on the row of the table I'm dealing with. Thusly: @implementation ImageDownloader ... @synthesize cacheIndex; static NSMutableArray *imageCache; -(void)startDownloadWithImageView:(UIImageView *)imageView andImageURL:(NSURL *)url withCacheIndex:(NSInteger)index { self.theImageView = imageView; self.cacheIndex = index; NSLog(@"Called to download %@ for imageview %@", url, self.theImageView); if ([imageCache objectAtIndex:index]) { NSLog(@"We have this image cached--using that instead"); self.theImageView.image = [imageCache objectAtIndex:index]; return; } self.activeDownload = [NSMutableData data]; NSURLConnection *conn = [[NSURLConnection alloc] initWithRequest:[NSURLRequest requestWithURL:url] delegate:self]; self.imageConnection = conn; [conn release]; } //build up the incoming data in self.activeDownload with calls to didReceiveData... - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSLog(@"Finished downloading."); UIImage *image = [[UIImage alloc] initWithData:self.activeDownload]; self.theImageView.image = image; NSLog(@"Caching %@ for %d", self.theImageView.image, self.cacheIndex); [imageCache insertObject:image atIndex:self.cacheIndex]; NSLog(@"Cache now has %d items", [imageCache count]); [image release]; } My index is getting through okay, I can see that by my NSLog output. But even after my insertObject: atIndex: call, [imageCache count] never leaves zero. This is my first foray into static variables, so I presume I'm doing something wrong. (The above code is heavily pruned to show only the main thing of what's going on, so bear that in mind as you look at it.)

  • Correctly encode characters in a PHP mail form ("I'm" turns to be "I\'m")

    - by Peanuts
    Hello guys, I'm testing a PHP mail form, a very barebones one, found here: <?php if(isset($_POST['submit'])) { //The form has been submitted, prep a nice thank you message $output = '<h3>Thanks for your message</h3>'; //Deal with the email $to = '[email protected]'; $subject = 'you have a mail'; $contactname = strip_tags($_POST['contactname']); $adress = strip_tags($_POST['adress']); $contactemail = strip_tags($_POST['contactemail']); $textmessage = strip_tags($_POST['textmessage']); $boundary =md5(date('r', time())); $headers = "From: My Site\r\nReply-To: [email protected]"; $message = "Name: ".$contactname."\n"; $message .= "Adress: ".$adress."\n"; $message .= "E-mail: ".$contactemail."\n"; $message .= "Message: ".$textmessage."\n"; mail($to, $subject, $message, $headers); } ?> The problem is I'm receiving an unwanted slash "\" everytime I write a single or a double quote in my message, so "I'm" appear as "I\'m" in my mailbox. I know it have to do with the way PHP distinguishes code quotes from only lecture quotes, but I wouldn't know what to add in my form to get it properly running. Any help is appreciated,

  • Form not sending full data

    - by gAMBOOKa
    I have a form with over 50 input fields. The input fields are divided into 5 jquery jabs within the form container. Here's a sample of what it looks like: <form action="admin/save" method="post" enctype="multipart/form-data"> <input type="hidden" name="type" value="department" /> <input type="hidden" name="id" value="21" /> <div id="tabs"> <ul> <li><a href="#tab-1">Tab 1</a><li> <li><a href="#tab-2">Tab 2</a><li> <li><a href="#tab-3">Tab 3</a><li> </ul> <div id="tab-1"> <label>Name</label> <input type="text" name="user-name" /> </div> <div id="tab-2"> <label>Address</label> <input type="text" name="user-address" /> </div> <div id="tab-3"> <label>Phone</label> <input type="text" name="user-phone" /> </div> </div> <input type="submit" value="Send" /> </form> I'm using PHP's Kohana framework, so admin maps to a controller, and save maps to the method action_save. When I output the $_POST variables in action_save, only 'type' and 'id' show up, all the other fields don't seem to submit their data. What could I be doing wrong?

  • How to access a superclass's class attributes in Python?

    - by Brecht Machiels
    Have a look at the following code: class A(object): defaults = {'a': 1} def __getattr__(self, name): print('A.__getattr__') return self.get_default(name) @classmethod def get_default(cls, name): # some debug output print('A.get_default({}) - {}'.format(name, cls)) try: print(super(cls, cls).defaults) # as expected except AttributeError: #except for the base object class, of course pass # the actual function body try: return cls.defaults[name] except KeyError: return super(cls, cls).get_default(name) # infinite recursion #return cls.__mro__[1].get_default(name) # this works, though class B(A): defaults = {'b': 2} class C(B): defaults = {'c': 3} c = C() print('c.a =', c.a) I have a hierarchy of classes each with its own dictionary containing some default values. If an instance of a class doesn't have a particular attribute, a default value for it should be returned instead. If no default value for the attribute is contained in the current class's defaults dictionary, the superclass's defaults dictionary should be searched. I'm trying to implement this using the recursive class method get_default. The program gets stuck in an infinite recursion, unfortunately. My understanding of super() is obviously lacking. By accessing __mro__, I can get it to work properly though, but I'm not sure this is a proper solution. I have the feeling the answer is somewhere in this article, but I haven't been able to find it yet. Perhaps I need to resort to using a metaclass?

  • categorize a set of phrases into a set of similar phrases

    - by Dingo
    I have a few apps that generate textual tracing information (logs) to log files. The tracing information is the typical printf() style - i.e. there are a lot of log entries that are similar (same format argument to printf), but differ where the format string had parameters. What would be an algorithm (url, books, articles, ...) that will allow me to analyze the log entries and categorize them into several bins/containers, where each bin has one associated format? Essentially, what I would like is to transform the raw log entries into (formatA, arg0 ... argN) instances, where formatA is shared among many log entries. The formatA does not have to be the exact format used to generate the entry (even more so if this makes the algo simpler). Most of the literature and web-info I found deals with exact matching, a max substring matching, or a k-difference (with k known/fixed ahead of time). Also, it focuses on matching a pair of (long) strings, or a single bin output (one match among all input). My case is somewhat different, since I have to discover what represents a (good-enough) match (generally a sequence of discontinuous strings), and then categorize each input entries to one of the discovered matches. Lastly, I'm not looking for a perfect algorithm, but something simple/easy to maintain. Thanks!

  • [Java] Nested methods vs "piped" methods, which is better?

    - by Michael Mao
    Hi: Since uni, I've programming in Java for 3 years, although I am not fully dedicated to this language, I have spent quite some time in it, nevertheless. I understand both ways, just curious which style do you prefer. public class Test{ public static void main(String[] args) { System.out.println(getAgent().getAgentName()); } private static Agent getAgent() { return new Agent(); }} class Agent{ private String getAgentName() { return "John Smith"; }} I am pretty happy with nested method calls such like the following public class Test{ public static void main(String[] args) { getAgentName(getAgent()); } private static void getAgentName(Agent agent) { System.out.println(agent.getName()); } private static Agent getAgent() { return new Agent(); }} class Agent { public String getName(){ return "John Smith"; }} They have identical output I saw "John Smith" twice. I wonder, if one way of doing this has better performance or other advantages over the other. Personally I prefer the latter, since for nested methods I can certainly tell which starts first, and which is after. The above code is but a sample, The code that I am working with now is much more complicated, a bit like a maze... So switching between the two styles often blows my head in no time.

  • WPF DataBinding to standard CLR properties in code-behind

    - by nukefusion
    Hi everyone, Just learning WPF databinding and have a gap in my understanding. I've seen a few similar questions on StackOverflow, but I'm still struggling in determining what I have done wrong. I have a simple Person class with a Firstname and Surname property (standard CLR properties). I also have a standard CLR property on my Window class that exposes an instance of Person. I've then got some XAML, with two methods of binding. The first works, the second doesn't. Can anybody help me to understand why the second method fails? There's no binding error message in the Output log. <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="clr-namespace:WpfApplication1" Title="Window1" Height="300" Width="300" DataContext="{Binding RelativeSource={RelativeSource Self}, Path=MyPerson}"> <StackPanel> <Label>My Person</Label> <WrapPanel> <Label>First Name:</Label> <Label Content="{Binding RelativeSource={RelativeSource AncestorType=Window, Mode=FindAncestor}, Path=MyPerson.FirstName}"></Label> </WrapPanel> <WrapPanel> <Label>Last Name:</Label> <Label Content="{Binding MyPerson.Surname}"></Label> </WrapPanel> </StackPanel> Edit: Ok, thanks so far. I've changed the second expression to: <Label Content="{Binding Surname}"></Label> I still can't get it to work though!

  • What's a good Java API for creating Word documents?

    - by Bill James
    I have a new app I'll be working on where I have to generate a Word document that contains tables, graphs, a table of contents and text. What's a good API to use for this? How sure are you that it supports graphs, ToCs, and tables? What are some hidden gotcha's in using them? Some clarifications: I can't output a PDF, they want a Word doc. They're using MS Word 2003 (or 2007), not OpenOffice Application is running on *nix app-server It'd be nice if I could start with a template doc and just fill in some spaces with tables, graphs, etc. Thanks for the help. Edit: Several good answers below, each with their own faults as far as my current situation. Hard to pick a "final answer" from them. Think I'll leave it open, and hope for better solutions to be created. Edit: The OpenOffice UNO project does seem to be closest to what I asked for. While POI is certainly more mainstream, it's too immature for what I want.

  • How can I create a horizontal table in a single foreach loop in MVC?

    - by GenericTypeTea
    Is there any way, in ASP.Net MVC, to condense the following code to a single foreach loop? <table class="table"> <tr> <td> Name </td> <% foreach (var item in Model) { %> <td> <%= item.Name %> </td> <% } %> </tr> <tr> <td> Item </td> <% foreach (var item in Model) { %> <td> <%= item.Company %> </td> <% } %> </tr> </table> Where model is a simple object: public class SomeObject { public virtual Name {get;set;} public virtual Company {get;set;} } This would output a table as follows: Name | Bob | Sam | Bill | Steve | Company | Builder | Fireman | MS | Apple | I know I could probably use an extension method to write out each row, but is it possible to build all rows using a single iteration over the model? This is a follow on from this question as I'm unhappy with my accepted answer and cannot believe I've provided the best solution.

  • SSH traffic over openvpn freezes under weird circumstances

    - by user289581
    I have an openvpn (version 2.1_rc15 at both ends) connection setup between two gentoo boxes using shared keys. it works fine for the most part. I use mysql, http, ftp, scp over the vpn with no problems. But when I ssh from the client to the server over the vpn, weird things happen. I can login, i can execute some commands. But if i try to run an ncurses application like top, or i try to cat a file, the connection will stall and I'll have to sever the ssh session. I can, for example, execute "echo blah; echo .; echo blah" and it will output the three lines of text over the ssh session fine. But if i execute "cat /etc/motd" the session will freeze the moment I press enter. While it seems like a terminal emulation problem it makes no sense why using the vpn would affect the ability for ssh to render things correctly. I am at a loss to explain why everything else works, including scp, but ssh just breaks over the vpn. Any thoughts ?

  • How can I build the Boost.Python example on Ubuntu 9.10?

    - by Gatlin
    I am using Ubuntu 9.10 beta, whose repositories contain boost 1.38. I would like to build the hello-world example. I followed the instructions here (http://www.boost.org/doc/libs/1%5F40%5F0/libs/python/doc/tutorial/doc/html/python/hello.html), found the example project, and issued the "bjam" command. I have installed bjam and boost-build.

As a side question, if I were to just willy-nilly start a project in an arbitrary directory, how would I write my jamroot?

  • How to change attribute on Scala XML Element

    - by Dave
    I have an XML file that I would like to map some attributes of in with a script. For example: <a> <b attr1 = "100" attr2 = "50"> </a> might have attributes scaled by a factor of two: <a> <b attr1 = "200" attr2 = "100"> </a> This page has a suggestion for adding attributes but doesn't detail a way to map a current attribute with a function (this way would make that very hard): http://www.scalaclass.com/book/export/html/1 What I've come up with is to manually create the XML (non-scala) linked-list... something like: // a typical match case for running thru XML elements: case Elem(prefix, e, attributes, scope, children @ _*) => { var newAttribs = attributes for(attr <- newAttribs) attr.key match { case "attr1" => newAttribs = attribs.append(new UnprefixedAttribute("attr1", (attr.value.head.text.toFloat * 2.0f).toString, attr.next)) case "attr2" => newAttribs = attribs.append(new UnprefixedAttribute("attr2", (attr.value.head.text.toFloat * 2.0f).toString, attr.next)) case _ => } Elem(prefix, e, newAttribs, scope, updateSubNode(children) : _*) // set new attribs and process the child elements } Its hideous, wordy, and needlessly re-orders the attributes in the output, which is bad for my current project due to some bad client code. Is there a scala-esque way to do this?

Output $VAR1 = { 'department' => { 'content' => 'Operations', 'role' => 'manager' }, 'name' => 'John Doe', 'sex' => 'M', 'age' => '43' }; How do I do, if I only want to get the role value. For this example I need to get Role = manager. Any advice or reference link is highly appreciated.

  • How to run the HelloWorld ODE from the browser?

    - by tikky
    I develop a simple hello world project by using Eclipse IDE. I can run it from the IDE (Web Services - Test with Web Services Explorer). From that it work perfectly, but if I try to access the http://localhost:8080/ode/processes/HelloWorld/ It gives some exceptions. org.apache.axis2.AxisFault: The endpoint reference (EPR) for the Operation not found is /ode/processes/HelloWorld/ and the WSA Action = null at org.apache.axis2.engine.DispatchPhase.checkPostConditions(DispatchPhase.java:86) at org.apache.axis2.engine.Phase.invoke(Phase.java:308) at org.apache.axis2.engine.AxisEngine.invoke(AxisEngine.java:212) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:132) at org.apache.axis2.transport.http.util.RESTUtil.invokeAxisEngine(RESTUtil.java:125) at org.apache.axis2.transport.http.util.RESTUtil.processURLRequest(RESTUtil.java:119) at org.apache.axis2.transport.http.AxisServlet$RestRequestProcessor.processURLRequest(AxisServlet.java:799) at org.apache.axis2.transport.http.AxisServlet.doGet(AxisServlet.java:242) at org.apache.ode.axis2.hooks.ODEAxisServlet.doGet(ODEAxisServlet.java:62) at javax.servlet.http.HttpServlet.service(HttpServlet.java:617) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:845) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Thread.java:729) What may be the issue and how to develop it as, input values through the web browser and get the output from it. Thank you.

  • Question about effective logging in C#

    - by MartyIX
    I've written a simple class for debugging and I call the method Debugger.WriteLine(...) in my code like this: Debugger.WriteLine("[Draw]", "InProgress", "[x,y] = " + x.ToString("0.00") + ", " + y.ToString("0.00") + "; pos = " + lastPosX.ToString() + "x" + lastPosY.ToString() + " -> " + posX.ToString() + "x" + posY.ToString() + "; SS = " + squareSize.ToString() + "; MST = " + startTime.ToString("0.000") + "; Time = " + time.ToString() + phase.ToString(".0000") + "; progress = " + progress.ToString("0.000") + "; step = " + step.ToString() + "; TimeMovementEnd = " + UI.MovementEndTime.ToString()); The body of the procedure Debugger.WriteLine is compiled only in Debug mode (directives #if, #endif). What makes me worry is that I often need ToString() in Debugger.WriteLine call which is costly because it creates still new strings (for changing number for example). How to solve this problem? A few points/questions about debugging/tracing: I don't want to wrap every Debugger.WriteLine in an IF statement or to use preprocessor directives in order to leave out debugging methods because it would inevitable lead to a not very readable code and it requires too much typing. I don't want to use any framework for tracing/debugging. I want to try to program it myself. Are Trace methods (http://msdn.microsoft.com/en-us/library/system.diagnostics.trace.aspx) left out if compiling in release mode? If it is so is it possible that my methods would behave similarly? http://msdn.microsoft.com/en-us/library/fht0f5be.aspx output = String.Format("You are now {0} years old.", years); Which seems nice. Is it a solution for my problem with ToString()?
