  • Insert multiple line breaks into a JavaScript string (regex) (CodeMirror)

    - by PJH
    I have a few strings and I would like to insert some line breaks into them at certain points. I figured out a few of the logistics but as a whole I can't seem to crack this problem, probably because I have limited experience with regex. Basically I have a long string of XML tags that is all on one line. I want to add line breaks at certain points to get the data more formatted and looking nice. I am using CodeMirror to display this data on a webpage but for some reason its all on line #1. So I need to go from something like this: <Sample><Name></Name><PhoneNumber><AreaCode></AreaCode><Number></Number></PhoneNumber></Sample> To something like this: <Sample> <Name></Name> <PhoneNumber> <AreaCode></AreaCode> <Number></Number> </PhoneNumber> </Sample> CodeMirror will take care of the rest of the formatting all I need to do is insert the line breaks in the right spot using regex or a loop of some sort. The Tags will or can change so I am guessing regex has to be used. I have had success inserting line breaks with \n and &#xD but can't seem to get regex to detect the proper locations. Any help would be greatly appreciated. Thanks. UPDATE I overlooked this but the brackets are in fact being sent as < and > So example tag would look like: &lt;PhoneNumber&gt; or &lt;/PhoneNumber&gt; So basically need to insert a \n after every &gt; that is a closing tag or a beginning tag that contains children tags.

  • Why is iPdb not displaying STOUT after my input?

    - by BryanWheelock
    I can't figure out why ipdb is not displaying stout properly. I'm trying to debug why a test is failing and so I attempt to use ipdb debugger. For some reason my Input seems to be accepted, but the STOUT is not displayed until I (c)ontinue. Is this something broken in ipdb? It makes it very difficult to debug a program. Below is an example ipdb session, notice how I attempt to display the values of the attributes with: user.is_authenticated() user_profile.reputation user.is_superuser The results are not displayed until 'begin captured stdout ' In [13]: !python manage.py test Creating test database... < SNIP remove loading tables nosetests ...E.. /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or user.is_authenticated() user_profile.reputation user.is_superuser c F /Users/Bryan/work/APP/forum/auth.py(93)can_retag_questions() 92 import ipdb; ipdb.set_trace() ---> 93 return user.is_authenticated() and ( 94 RETAG_OTHER_QUESTIONS <= user_profile.reputation < EDIT_OTHER_POSTS or c .....EE......

    Its already too long i am struggling with this issue. After searching a lot I decided to post a question here. What my app does Captures photo Uploads the photo on the wall of the page Displays the facebook page wall in a UIWebview after upload is complete Everything was working as expected 4 days back :) Suddenly something went wrong :( Code NSString *facebookPageURL =@"https://m.facebook.com/pages/<myPageName>/<myPageID>?v=wall" UIWebView *webView = [[UIWebView alloc] initWithFrame:kAppFrame]; [webView setUserInteractionEnabled:NO]; [webView setBackgroundColor:[UIColor clearColor]]; webView.delegate = self; [webView setHidden: YES]; NSURL *url = [NSURL URLWithString:[facebookPageURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] relativeToURL:[NSURL URLWithString:@"http://login.facebook.com"]]; NSMutableURLRequest *request = nil; if(url) request = [NSMutableURLRequest requestWithURL:url]; [webView loadRequest:request]; [self.view addSubview:webView]; [webView reload]; [self.view bringSubviewToFront:webView]; webView = nil; Scenario If I open the url facebookPageURL in Safari in iOS Simulator it works well If I open the url in any browser on Mac it works well In webView I see a white screen If I change the facebookPageURL to remove ?v=wall to ?v=info I am stil able to see the page.(not blank screen atleast).

  • When should I be cautious using about data binding in .NET?

    - by Ben McCormack
    I just started working on a small team of .NET programmers about a month ago and recently got in a discussion with our team lead regarding why we don't use databinding at all in our code. Every time we work with a data grid, we iterate through a data table and populate the grid row by row; the code usually looks something like this: Dim dt as DataTable = FuncLib.GetData("spGetTheData ...") Dim i As Integer For i = 0 To dt.Rows.Length - 1 '(not sure why we do not use a for each here)' gridRow = grid.Rows.Add() gridRow(constantProductID).Value = dt("ProductID").Value gridRow(constantProductDesc).Value = dt("ProductDescription").Value Next '(I am probably missing something in the code, but that is basically it)' Our team lead was saying that he got burned using data binding when working with Sheridan Grid controls, VB6, and ADO recordsets back in the nineties. He's not sure what the exact problem was, but he remembers that binding didn't work as expected and caused him some major problems. Since then, they haven't trusted data binding and load the data for all their controls by hand. The reason the conversation even came up was because I found data binding to be very simple and really liked separating the data presentation (in this case, the data grid) from the in-memory data source (in this case, the data table). "Loading" the data row by row into the grid seemed to break this distinction. I also observed that with the advent of XAML in WPF and Silverlight, data-binding seems like a must-have in order to be able to cleanly wire up a designer's XAML code with your data. When should I be cautious of using data-binding in .NET?

  • 'echo' or drop out of 'programming' write HTML then start PHP code again

    - by thecoshman
    For the most part, when I want to display some HTML code to be actually rendered I would use a 'close PHP' tag, write the HTML, then open the PHP again. eg <?php // some php code ?> <p>HTML that I want displayed</p> <?php // more php code ?> But I have seen lots of people who would just use echo instead, so they would have done the above something like <?php // some php code echo("<p>HTML that I want displayed</p>"); // more php code ?> Is their any performance hit for dropping out and back in like that? I would assume not as the PHP engine would have to process the entire file either way. What about when you use the echo function in the way that dose not look like a function, eg echo "<p>HTML that I want displayed</p>" I would hope that this is purely a matter of taste, but I would like to know if I was missing out on something. I personally find the first way preferable (dropping out of PHP then back in) as it helps draw a clear distinction between PHP and HTML and also lets you make use of code highlighting and hinting for your HTML, which is always handy.

  • PHP-REGEX: accented letters matches non-accented ones, and visceversa. How to achive it?

    - by Lightworker
    I want to do the typical higlight code. So I have something like: $valor = preg_replace("/(".$_REQUEST['txt_search'].")/iu", "<span style='background-color:yellow; font-weight:bold;'>\\1</span>", $valor); Now, the request word could be something like "josé". And with it, I want "jose" or "JOSÉ" or "José" or ... highlighted too. With this expression, if I write "josé", it matches "josé" and "JOSÉ" (and all the case variants). It always matches the accented variants only. If I search "jose", it matches "JOSE", "jose", "Jose"... but not the accented ones. So I've partially what I want, cause I have case insensitive on accented and non-accented separately. I need it fully combined, wich means accent (unicode) insensitive, so I can search "jose", and highlight "josé", "josÉ", "José", "JOSE", "JOSÉ", "JoSé", ... I don't want to do a replace of accents on the word, cause when I print it on screen I need to see the real word as it comes. Any ideas? Thanks!

  • jQuery eval of ajax inline script not throwing errors

    - by Josh
    http://stackoverflow.com/questions/606794/debugging-ajax-code-with-firebug This question is quite similar, though old and without real answers. I'm currently putting together an app that has scripts that get loaded in with an ajax request. An example: var main = _main.get(); main.load( someurl ); Where someurl is a page that contains an inline script element: <script type="text/javascript"> $(document).ready( function(){ var activities = new activities(); activities.init(); }); </script> jQuery will do a line by line eval of js that lives in inline script tags. The problem is, I get no errors or any information whatsoever in firebug when something goes awry. Does anyone have a good solution for this? Or a better practice for loading pages which contain javascript functionality? Edit: A little progress... so at the top of the page that is being loaded in via ajax, I have another script that was being included like this: <script type="text/javascript" src="javascript/pages/activities.js"></script> When I moved the inline $(document).ready() code in the page to the end of this included file, instead, syntax errors were now properly getting thrown. As an aside, I threw a console.log() into the inline script tag, and it was being logged just fine. I also tried removing the $(document).ready() altogether, and also switching it out for a $(window).load() event. No difference. May have something to do with the inline scripts dependency on the included activities.js, I guess. :: shakes head :: javascript can be a nightmare.

  • What's a good way of building up a String where you specific start and end locations?

    - by Michael Campbell
    (java 1.5) I have a need to build up a String, in pieces. I'm given a set of (sub)strings, each with a start and end point of where they belong in the final string. Was wondering if there were some canonical way of doing this. This isn't homework, and I can use any licensable OSS, such as jakarta commons-lang StringUtils etc. My company has a solution using a CharBuffer, and I'm content to leave it as is (and add some unit tests, of which there are none (?!)) but the code is fairly hideous and I would like something easier to read. As I said this isn't homework, and I don't need a complete solution, just some pointers to libraries or java classes that might give me some insight. The String.Format didn't seem QUITE right... I would have to honor inputs too long and too short, etc. Substrings would be overlaid in the order they appear (in case of overlap). As an example of input, I might have something like: String:start:end FO:0:3 (string shorter than field) BAR:4:5 (String larger than field) BLEH:5:9 (String overlays previous field) I'd want to end up with FO BBLEH 01234567890

  • How can I place validating constraints on my method input parameters?

    - by rcampbell
    Here is the typical way of accomplishing this goal: public void myContractualMethod(final String x, final Set<String> y) { if ((x == null) || (x.isEmpty())) { throw new IllegalArgumentException("x cannot be null or empty"); } if (y == null) { throw new IllegalArgumentException("y cannot be null"); } // Now I can actually start writing purposeful // code to accomplish the goal of this method I think this solution is ugly. Your methods quickly fill up with boilerplate code checking the valid input parameters contract, obscuring the heart of the method. Here's what I'd like to have: public void myContractualMethod(@NotNull @NotEmpty final String x, @NotNull final Set<String> y) { // Now I have a clean method body that isn't obscured by // contract checking If those annotations look like JSR 303/Bean Validation Spec, it's because I borrowed them. Unfortunitely they don't seem to work this way; they are intended for annotating instance variables, then running the object through a validator. Which of the many Java design-by-contract frameworks provide the closest functionality to my "like to have" example? The exceptions that get thrown should be runtime exceptions (like IllegalArgumentExceptions) so encapsulation isn't broken.

  • x86_64 printf segfault after brk call

    - by gmb11
    While i was trying do use brk (int 0x80 with 45 in %rax) to implement a simple memory manager program in assembly and print the blocks in order, i kept getting segfault. After a while i could only reproduce the error, but have no idea why is this happening: .section .data helloworld: .ascii "hello world" .section .text .globl _start _start: push %rbp mov %rsp, %rbp movq $45, %rax movq $0, %rbx #brk(0) should just return the current break of the programm int $0x80 #incq %rax #segfault #addq $1, %rax #segfault movq $0, %rax #works fine? #addq $1, %rax #segfault again? movq $helloworld, %rdi call printf movq $1, %rax #exit int $0x80 In the example here, if the commented lines are uncommented, i have a segfault, but some commands (like de movq $0, %rax) work just fine. In my other program, the first couple printf work, but the third crashes... Looking for other questions, i heard that printf sometimes allocates some memory, and that the brk shouldn't be used, because in this case it corrupts the heap or something... I'm very confused, does anyone know something about that? EDIT: I've just found out that for printf to work you need %rax=0.

  • GLSL shader render to texture not saving alpha value

    - by quadelirus
    I am rendering to a texture using a GLSL shader and then sending that texture as input to a second shader. For the first texture I am using RGB channels to send color data to the second GLSL shader, but I want to use the alpha channel to send a floating point number that the second shader will use as part of its program. The problem is that when I read the texture in the second shader the alpha value is always 1.0. I tested this in the following way: at the end of the first shader I did this: gl_FragColor(r, g, b, 0.1); and then in the second texture I read the value of the first texture using something along the lines of vec4 f = texture2D(previous_tex, pos); if (f.a != 1.0) { gl_FragColor = vec4(0.0, 0.0, 0.0, 1.0); return; } No pixels in my output are black, whereas if I change the above code to read gl_FragColor(r, g, 0.1, 1.0); //Notice I'm now sending 0.1 for blue and in the second shader vec4 f = texture2D(previous_tex, pos); if (f.b != 1.0) { gl_FragColor = vec4(0.0, 0.0, 0.0, 1.0); return; } All the appropriate pixels are black. This means that for some reason when I set the alpha value to something other than 1.0 in the first shader and render to a texture, it is still seen as being 1.0 by the second shader. Before I render to texture I glDisable(GL_BLEND); It seems pretty clear to me that the problem has to do with OpenGL handling alpha values in some way that isn't obvious to me since I can use the blue channel in the way I want, and figured someone out there will instantly see the problem.

  • Rest WebService error handling.

    - by Pratik
    Hi there, I am using RestWebservice for few basic operations , like creating/searching. The request xml looks something like this <customer> <name/> ..... </customer> For a successful operation I return the same customer XML with extra fields populated in it(eg. systemId etc which we blank in the request) . with Response.Status=2000 For an unsuccessful operation i return something like this with different error codes . e.g Response.Status = 422(Unprocessable entity) Response.Status= 500(Internal Server Error) and few others.. <errors> <error> An exception occurred while creating the customer</error> <error> blah argument is not valid.</error> </errors> Now i am not sure , whether this is the correct way of sending the errors to the client. Maybe it should be present in the header of the response. I will really appreciate any help. Thanks!

  • calloc v/s malloc and time efficiency

    - by yCalleecharan
    Hi, I've read with interest the post "c difference between malloc and calloc". I'm using malloc in my code and would like to know what difference I'll have using calloc instead. My present (pseudo)code with malloc: Scenario 1 int main() { allocate large arrays with malloc INITIALIZE ALL ARRAY ELEMENTS TO ZERO for loop //say 1000 times do something and write results to arrays end for loop FREE ARRAYS with free command } //end main If I use calloc instead of malloc, then I'll have: Scenario2 int main() { for loop //say 1000 times ALLOCATION OF ARRAYS WITH CALLOC do something and write results to arrays FREE ARRAYS with free command end for loop } //end main I have three questions: Which of the scenarios is more efficient if the arrays are very large? Which of the scenarios will be more time efficient if the arrays are very large? In both scenarios,I'm just writing to arrays in the sense that for any given iteration in the for loop, I'm writing each array sequentially from the first element to the last element. The important question: If I'm using malloc as in scenario 1, then is it necessary that I initialize the elements to zero? Say with malloc I have array z = [garbage1, garbage2, garbage 3]. For each iteration, I'm writing elements sequentially i.e. in the first iteration I get z =[some_result, garbage2, garbage3], in the second iteration I get in the first iteration I get z =[some_result, another_result, garbage3] and so on, then do I need specifically to initialize my arrays after malloc?

  • Knowing the selections made on a 'multichooser' box in a mechanical turk hit (using Command Line Too

    - by gveda
    Hi All, I am new to Amazon Mechanical Turk, and wanted to create a hit with a qualification task. I am using the command line tools interface. One of the questions in my qualification task involves users selecting a number of options. I use a 'multichooser' selection type. Now I want to grade the responses based on the selections, where each selection has a different score. So for example, s1 has a score of 5, s2 of 10, s3 of 6, and so on. If the user selects s1 and s3, he/she gets a score of 11. Unfortunately, doing something like the following does not work: <AnswerOption> <SelectionIdentifier>s1</SelectionIdentifier> <AnswerScore>5</AnswerScore> </AnswerOption> <AnswerOption> <SelectionIdentifier>s2</SelectionIdentifier> <AnswerScore>10</AnswerScore> </AnswerOption> <AnswerOption> <SelectionIdentifier>s3</SelectionIdentifier> <AnswerScore>6</AnswerScore> </AnswerOption> If I do this, when I select multiple things, I get a score of 0. If I select only one option, say s1, then I get the appropriate score. Can you please help me on how to go about this? I could ask the same question 5 times with the same options, but then users might choose the same answer multiple times - something I wish to avoid. Thanks! Gaurav

  • Base Href vs. .htaccess RewriteBase

    - by Wayne
    Normally I use <base href="http://domain.com/" /><!--[if ie]></base><![endif]--> I haven't tried much with RewriteBase, I normally get confused and keep changing it till it works. Which method would be best, I obviously find the best solution because the links stay the same so that no links are broken most of the time when attaching a css file, e.g. http://domain.com/css/main.css It just always stay the same when accessing to sub-directories. Although, when I don't use the tag, and I access to a sub directory, it breaks the css links when I use <link href="css/main.css" rel="stylesheet" type="text/css" /> As my PHP documents would include the header, <?php include("include/global_header.php"); ?> If I do that without the I would have to use: <link href="../css/main.css" rel="stylesheet" type="text/css" /> Which can break when accessing to a sub-directory. So... does the RewriteBase work the same as the ? Your thoughts.

  • Returning from dll (Asynchronous sockets)

    - by Juha
    I am trying to do a simple http-server in (c++) dll-file that I can use from managed (C#) application with P/Invoke. I was trying to do this with asynchronous functions (WSAAsyncSelect() and stuff), so that I could manage server by calling functions inside dll whenever needed and after that it would return to my main program. Now I'm not sure if that is even possible. It seems that "main function" in dll, the function that starts the server, has to include message loop or something and since it's a loop, it doesn't return from dll ever. Could I somehow do this message stuff in my managed application and call some function in dll when there is something to do? Or is it even possible to do this stuff in one thred? I would really like to avoid all concurrency stuff. The dll looks now basicly the same as here, main function is the one that I call from managed C# program and would like to return to there after calling the function. http://www.winsocketdotnetworkprogramming.com/winsock2programming/winsock2advancediomethod5b.html I'm quite noob in windows programming, and never even heard of this message-queue or message-loop.

  • Dojo DataGrid, programmatic creation

    - by djna
    I'm trying to create a DataGrid dynamically. Declarative creation is working fine: A source of data: <span dojoType="dojo.data.ItemFileReadStore" jsId="theStore" url="dataonly001.json"> </span> a simple layout: <script type="text/javascript" > var layout = [ { field: 'custId', name: 'Id', } // more items elided ... ]; </script> The grid: <body class="tundra" id="mainbody"> <div id="grid" dojoType="dojox.grid.DataGrid" store="theStore" structure="layout" autoWidth="true" ></div> </body> And I get the grid displayed nicely. Instead, I want to create the grid dynamically. For the sake of figuring out what's broken I've tried to use exactly the same layout and store, removing just teh grid declaration and adding this script: <script type="text/javascript" djConfig="parseOnLoad: true, debugAtAllCosts: true"> dojo.addOnLoad(function(){ // initialise and lay out home page console.log("Have a store:" + theStore); console.log("Have a structure:" + layout); var grid = new dojox.grid.DataGrid({ id:"grid", store : theStore, clientSort : "true", structure : layout }); grid.startup(); dojo.place(grid.domNode, dojo.body(), "first"); }); </script> The effect that I get is a completely empty rectangle is displayed. Using FireBug I can see that the DataGrid widget is created but that it has no rows or columns. So my guess is that the datastore or layout are not being passed correctly. However, it does appear that at the point of creation the values of theStore and layout are correct. Suggestions please, or indeed a working example of a programmic grid might solve the problem.

  • Bash and regex problem : check for tokens entered into a Coke vending machine

    - by Michael Mao
    Hi all: Here is a "challenge question" I've got from Linux system programming lecture. Any of the following strings will give you a Coke if you kick: L = { aaaa, aab, aba, baa, bb, aaaa"a", aaaa"b", aab"a", … ab"b"a, ba"b"a, ab"bbbbbb"a, ... } The letters shown in wrapped double quotes indicate coins that would have fallen through (but those strings are still part of the language in this example). Exercise (a bit hard) show this is the language of a regular expression And this is what I've got so far : #!/usr/bin/bash echo "A bottle of Coke costs you 40 cents" echo -e "Please enter tokens (a = 10 cents, b = 20 cents) in a sequence like 'abba' :\c" read tokens #if [ $tokens = aaaa ]||[ $tokens = aab ]||[ $tokens = bb ] #then # echo "Good! now a coke is yours!" #else echo "Thanks for your money, byebye!" if [[ $token =~ 'aaaa|aab|bb' ]] then echo "Good! now a coke is yours!" else echo "Thanks for your money, byebye!" fi Sadly it doesn't work... always outputs "Thanks for your money, byebye!" I believe something is wrong with syntax... We didn't provided with any good reference book and the only instruction from the professor was to consult "anything you find useful online" and "research the problem yourself" :( I know how could I do it in any programming language such as Java, but get it done with bash script + regex seems not "a bit hard" but in fact "too hard" for anyone with little knowledge on something advanced as "lookahead"(is this the terminology ?) I don't know if there is a way to express the following concept in the language of regex: Valid entry would consist of exactly one of the three components : aaaa, aab and bb, regardless of order, followed by an arbitrary sequence of a or b's So this is what is should be like : (a{4}Ua{2}bUb{2})(aUb)* where the content in first braces is order irrelevant. Thanks a lot in advance for any hints and/or tips :)

  • WPF compile error "IDictionary must have a Key attribute"

    - by the empirical programmer
    I've created control styles I want to use among multiple xaml pages in my WPF app. To do this I created a Resources.xaml and added the styles there. Then in my pages I add this code <Grid.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="pack://application:,,,/SampleEventTask;component/Resources.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Grid.Resources> On two pages this works fine, but on the 3rd page I get a compile error that says: All objects added to an IDictionary must have a Key attribute or some other type of key associated with them. If I add a key to this, as such ResourceDictionary x:Key="x", then the compile error goes but on running the app it errors finding the style. I can make the compile error go away and have the app run by just moving original (no key specified) "ResourceDictionary" xaml from the top level Grid into a contained Grid on that page. But I don't understand what is going on here. Any suggestions as to what the problem is, I'm just missing something or doing something incorrectly. Is there a better way to share styles? thanks

Over time I can transfer jobs from one instance to another by switching them to a readonly mode on the source instance, spinning them up on the target instance, and then spinning the original down on the source instance. If I have too many jobs then I can tell Azure to spin up extra role instance, and use them for new jobs. Conversely if my load drops (e.g. during the night) then I can consolidate outstanding jobs to a few machines and tell Azure to give me fewer instances. The trouble is that (as I understand it) Azure provides no mechanism to allow me to decide which instance to stop. Thus I cannot know which servers to consolidate onto, and some of my jobs will die when their instance stops, causing delays for users while I restart those jobs on surviving instances. Idea 1: I decide which instance to stop, and return from its Run(). I then tell Azure to reduce my instance count by one, and hope it concludes that the broken instance is a good candidate. Has anyone tried anything like this? Idea 2: I predefine a whole bunch of different worker roles, with identical contents. I can individually stop and start them by switching their instance count from zero to one, and back again. I think this idea would work, but I don't like it because it seems to go against the natural Azure way of doing things, and because it involves me in a lot of extra bookkeeping to manage the extra worker roles. Idea 3: Live with it. Any better ideas?

  • Sweave/R - Automatically generating an appendix that contains all the model summaries/plots/data pro

    - by John Horton
    I like the idea of making research available at multiple levels of detail i.e., abstract for the casually curious, full text for the more interested, and finally the data and code for those working in the same area/trying to reproduce your results. In between the actual text and the data/code level, I'd like to insert another layer. Namely, I'd like to create a kind of automatically generated appendix that contains the full regression output, diagnostic plots, exploratory graphs data profiles etc. from the analysis, regardless of whether those plots/regressions etc. made it into the final paper. One idea I had was to write a script that would examine the .Rnw file and automatically: Profile all data sets that are loaded (sort of like the Hmisc(?) package) Summarize all regressions - i.e., run summary(model) for all models Present all plots (regardless of whether they made it in the final version) The idea is to make this kind of a low-effort, push-button sort of thing as opposed to a formal appendix written like the rest of a paper. What I'm looking for is some ideas on how to do this in R in a relatively simple way. My hunch is that there is some way of going through the namespace, figuring out what something is and then dumping into a PDF. Thoughts? Does something like this already exist?

  • Trouble creating a Java policy server for a simple Flash app

    - by simonwulf
    I'm trying to create a simple Flash chat application for educational purposes, but I'm stuck trying to send a policy file from my Java server to the Flash app (after several hours of googling with little luck). The policy file request reaches the server that sends a harcoded policy xml back to the app, but the Flash app doesn't seem to react to it at all until it gives me a security sandbox error. I'm loading the policy file using the following code in the client: Security.loadPolicyFile("xmlsocket://myhostname:" + PORT); The server recognizes the request as "<policy-file-request/" and responds by sending the following xml string to the client: public static final String POLICY_XML = "<?xml version=\"1.0\"?>" + "<cross-domain-policy>" + "<allow-access-from domain=\"*\" to-ports=\"*\" />" + "</cross-domain-policy>"; The code used to send it looks like this: try { _dataOut.write(PolicyServer.POLICY_XML + (char)0x00); _dataOut.flush(); System.out.println("Policy sent to client: " + PolicyServer.POLICY_XML); } catch (Exception e) { trace(e); } Did I mess something up with the xml or is there something else I might have overlooked?

  • CSS Parser - Insert mtimes

    - by brad
    What command line tool can I use to automatically insert mtimes into urls in my css files for the purposes of breaking the cache? /* before */ .example { background: url(example.jpg); } /* after */ .example { background: url(example.jpg?1271298451); } Also, I would like this tool to spit out the latest mtime as the css files mtime. (If the css file is still cached then the new urls will not get to the client.) In searching the web, I have found very few tools that can do this. I am even considering rolling my own, but have found very little in the way of css parsers that are actively maintained. A candidate should be: fast (I don't want to wait 30 seconds on deployment) command line accessible (something like "cat foo.css bar.css | cssmtime out.css") What I've found so Far yui compressor - initially I thought I would extend the yui compressor to do this, but found that it is implemented as a bunch of regex's and not a parser. csstidy - last release was in 2007 and development has been suspended, but does have an option for inserting mtimes (also written in php, something I have no experience in) cssutils - python sac implementation - seems to be actively maintained, but also seems like overkill for my needs. Also, written in python which I have experience with csspool - ruby sac implementation - I don't know much ruby, but would like to learn other sac implementations - There are several java implementations, and a c implementation neither of which I know much about What's your experience? Have you used any of these libraries? Was the experience positive? Would you recommend I go with them for my purposes?

  • C#/Java: Proper Implementation of CompareTo when Equals tests reference identity

    - by Paul A Jungwirth
    I believe this question applies equally well to C# as to Java, because both require that {c,C}ompareTo be consistent with {e,E}quals: Suppose I want my equals() method to be the same as a reference check, i.e.: public bool equals(Object o) { return this == o; } In that case, how do I implement compareTo(Object o) (or its generic equivalent)? Part of it is easy, but I'm not sure about the other part: public int compareTo(Object o) { if (! (o instanceof MyClass)) return false; MyClass other = (MyClass)o; if (this == other) { return 0; } else { int c = foo.CompareTo(other.foo) if (c == 0) { // what here? } else { return c; } } } I can't just blindly return 1 or -1, because the solution should adhere to the normal requirements of compareTo. I can check all the instance fields, but if they are all equal, I'd still like compareTo to return a value other than 0. It should be true that a.compareTo(b) == -(b.compareTo(a)), and the ordering should stay consistent as long as the objects' state doesn't change. I don't care about ordering across invocations of the virtual machine, however. This makes me think that I could use something like memory address, if I could get at it. Then again, maybe that won't work, because the Garbage Collector could decide to move my objects around. hashCode is another idea, but I'd like something that will be always unique, not just mostly unique. Any ideas?
