  • Server Emulator Design Pattern

    - by adisembiring
    I wanna build server socket emulator, but I want implement some design pattern there. I will described my case study that I have simplified like these: My Server Socket will always listen client socket. While some request message come from the client socket, the server emulator will response the client through the socket. the response is response code. '00' will describe request message processed successfully, and another response code expect '00' will describe there are some error while processing the message request. IN the server there are some UI, this UI contain check response parameter such as. response code timeout interval While the server want to response the client message, the response code taken from input parameter response form UI check the timeout interval, it will create sleep thread and the interval taken from timeout interval input from UI. I have implement the function, but I create it in one class. I feel it so sucks. Can you suggest me what class / interface that I must create to refactor my code.

  • "Anagram solver" based on statistics rather than a dictionary/table?

    - by James M.
    My problem is conceptually similar to solving anagrams, except I can't just use a dictionary lookup. I am trying to find plausible words rather than real words. I have created an N-gram model (for now, N=2) based on the letters in a bunch of text. Now, given a random sequence of letters, I would like to permute them into the most likely sequence according to the transition probabilities. I thought I would need the Viterbi algorithm when I started this, but as I look deeper, the Viterbi algorithm optimizes a sequence of hidden random variables based on the observed output. I am trying to optimize the output sequence. Is there a well-known algorithm for this that I can read about? Or am I on the right track with Viterbi and I'm just not seeing how to apply it?

  • Error when trying to refer to a field by name

    I am getting an error (document.my_formm.fieldName.value is null or not an object) from the below code: <html> <head> <title>(Type a title for your page here)</title> <script language=JavaScript> function check_length(my_formm,fieldName) { alert(fieldName); alert(document.my_formm.fieldName.value); } </script> </head> <body> <form name=my_form method=post> <input type="text" onChange=check_length("my_form","my_text"); name=my_text rows=4 cols=30 value=""> <br> <input size=1 value=50 name=text_num> Characters Left </form> </body> </html>

  • All Permutations of a string when corresponding characters are not in the same place

    - by r20rock
    I need all possible permutations of a given string such that no character should remain at the same place as in the input string. Eg. : for input "ask" Output: all possible permutaions like "ksa", "kas"... such that 'a' is not in the 1st position , 's' is not in the 2nd positions and so on... in any permutation. I only need the count of such possible permutations I can do this by generating all permutations and filtering them but I need a very efficient way of doing this. All characters in the string are "UNIQUE" Preferred language C++.

  • Conversion of DOM element selection code to jQuery

    - by Tom McDonnell
    I have a large Javascript codebase to convert to jQuery. The code is structured such that DOM elements are created in Javascript (using a library called DomBuilder), and saved to variables if they will be needed later, before being added to the DOM. Eg. var inputs = { submitConfirm: INPUT({type: 'button', value: 'Submit'}), submitCancel : INPUT({type: 'button', value: 'Cancel'}) }; document.appendChild(inputs.submitConfirm); Then later for example... inputs.submitCancel.style.display = 'none'; inputs.submitCancel.addEventListener('click', onClickSubmitCancel, false); My problem is that jQuery seems to lack a way of manipulating DOM elements directly, as opposed to selecting them first (with for example $('#submitCancel'). Can anyone suggest a way to directly translate the last two Javascript lines given above to use jQuery, given that the DOM elements are already available, and so do not need to be selected?

  • How to access private static target field in aspect in AspectJ?

    - by LihO
    I have a simple class Main with private static int x and an aspect that should output the old value of x before it is reassigned: public class Main { private static int x; public static void main(String[] args) { foo(7); } public static void foo(int y) { x = y; } } and MonitorX.aj: public aspect MonitorX { before() : set(static int Main.x){ System.out.println(Main.x); } } which doesn't work since I can't access private x using Main.x. I've also tried: before(int t) : set(static int Main.x) && target(t){ System.out.println(t); } which doesn't work either (nothing is outputted, if I try to output string, it seems that the aspect isn't invoked at all). However printing out the new value that is being assigned works: before(int newVal) : set(static int Main.x) && args(newVal){ System.out.println(newVal); } What am I missing?

  • Connect to an existing process

    - by user360807
    Hole thing is happening on the mac os x. Let's assume that I've opened an program by clicking on an .app icon. It's a python program with GUI which has a separate process that waits for a user input. But as I've opened it by clickin .app icon I dont have access to it's input as I would have if I opened it in Terminal. And the question is: How can I connect new Terminal window to this running program? I tried pipes but I'm not sure how to use them correctly. My guess was to find PID of the app that is running and then pipe to this program by giving a PID. But I have no idea how to do it. I hope you were able to understand what's the problem. Sorry for my weak english :)

  • Floated DIVs not flowing properly

    - by NightMICU
    Hi everyone, I am working on a photo gallery, each thumbnail is in its own DIV and floated to the left in a containing DIV. It has been displaying properly up until vertical thumbnails entered the equation. Now, when the next row should start, the first item of the following row is to the left of the last vertical DIV (thumbnail), rather than flush to the left of the containing DIV. Here is the CSS: #galleryBox { width: 650px; background: #fff; margin: auto; padding: 10px; text-align: center; overflow: auto; } .item { display: block; margin: 10px; padding: 20px 5px 5px 5px; float: left; background: url('/images/content_bottom.png') repeat-x scroll bottom #828282; } and the HTML: <div id="galleryBox" class="ui-corner-all"> <div id="file" class="ui-corner-all"> <form name="uploadPhoto" id="uploadPhoto" method="post" action="" enctype="multipart/form-data"> <p><label for="photo">Photo:</label><input type="file" name="photo" id="photo"/></p> <p><label for="caption">Caption: <small>Optional</small></label><input type="text" id="caption" name="caption"/></p> <p align="center"><input type="submit" value="Upload" name="send" id="send" class="addButton ui-state-default ui-corner-all"/></p> </form> <a name="thumbs"></a> </div> <div class="item ui-corner-all"> <a href="http://tapp-essexvfd.org/gallery/photos/201004211802.jpg" class="lightbox" title="test1"> <img src="http://tapp-essexvfd.org/gallery/photos/thumbs/201004211802_thumb.jpg" alt="test1"/></a><br/> <p><span class="label">test1</span></p> </div> <div class="item ui-corner-all"> <a href="http://tapp-essexvfd.org/gallery/photos/201004211803.jpg" class="lightbox" title="test3"> <img src="http://tapp-essexvfd.org/gallery/photos/thumbs/201004211803_thumb.jpg" alt="test3"/></a><br/> <p><span class="label">test3</span></p> </div> </div>

  • What is the best data structure and algorithm for comparing a list of strings?

    - by Chiraag E Sehar
    I want to find the longest possible sequence of words that match the following rules: Each word can be used at most once All words are Strings Two strings sa and sb can be concatenated if the LAST two characters of sa matches the first two characters of sb. In the case of concatenation, it is performed by overlapping those characters. For example: sa = "torino" sb = "novara" sa concat sb = "torinovara" For example, I have the following input file, "input.txt": novara torino vercelli ravenna napoli liverno messania noviligure roma And, the output of the above file according to the above rules should be: torino novara ravenna napoli livorno noviligure since the longest possible concatenation is: torinovaravennapolivornovilligure Can anyone please help me out with this? What would be the best data structure for this?

  • Prolog - Finding the current directory, relative directory for 'tell' predicate

    - by Bharat
    I'm having trouble trying to figure out how to get prolog to spit out a text file where I want it to. I'm currently doing a bunch of operations and then using tell('output.txt') to record the output. Now the problem is that when I do this, it creates this file in the SWI \bin\ folder. I was wondering if there's a way to make it create this file in the directory containing the actual .pl file. So even if the file was moved (and it will be), the text file gets created right where the source file is. Long story short, is there a way to get the location of the source file once the source file has been consulted? Many Thanks!

  • Why does my Perl regular expression only find the last occurrence?

    - by scharan
    I have the following input to a Perl script and I wish to get the first occurrence of NAME="..." strings in each of the <table>...</table> structures. The entire file is read into a single string and the regex acts on that input. However, the regex always returns the last occurrence of NAME="..." strings.

Basically I want to get the details from FILE 1 and compare with FILE2 (master list) . Example : A1 in FILE2 was not available in FILE1 , so in output file we have “-“ for 1st three fields and rest from FILE2 . Now, we have A11 and we got the detail in FILE1. So we write details of A11 from both File 1 & 2

  • Entity Aspect (in Spring)

    - by niklassaers
    Hi guys, I'm having a bit of a problem defining my aspects. I've got a bunch of entities that I'd like to profile the get-methods in, so I've written the following pointcut and method @Pointcut("execution(* tld.myproject.data.entities.*.get*()") public void getEntityProperty() {} @Around("getEntityProperty()") public Object profileGetEntityProperty(ProceedingJoinPoint pjp) throws Throwable { long start = System.currentTimeMillis(); String name = pjp.getSignature().getName(); Object output = pjp.proceed(); long elapsedTime = System.currentTimeMillis() - start; if(elapsedTime > 100) System.err.println("profileGetEntityProperty: Entity method " + name + " execution time: " + elapsedTime + " ms."); return output; } I've got weaving turned on in my configuration, and aspects weaving into the business layer work just fine. Is my pointcut correctly written? Or is there something about entities that make them non-weavable? (my entity is prefixed with @Entity before the class definition) Cheers Nik

  • How to hide editor-label for public property when calling EditorFor(...)?

    - by FreshCode
    When calling Html.EditorFor(m => m), where m is a public class with public properties, a hidden input and a label are displayed for properties with the [HiddenInput] attribute. How can I hide the label without making it private or creating an editor template? Example public class User { [HiddenInput] public Guid ID { get; set; } // should not be displayed in editor template public string Name { get; set; } // should be editable } Undesired result for ID property by EditorFor(...) with label <div class="editor-label"> <label for="ID">ID</label> <!-- Why is this here? --> </div> <div class="editor-field"> <input id="ID" name="ID" type="hidden" value=""> </div>

  • jQuery Validation using the class instead of the name value

    - by Matt
    Hi, I'd like to validate a form using the jquery validate plugin, but I'm unable to use the 'name' value within the html - as this is a field also used by the server app. Specifically, I need to limit the number of checkboxes checked from a group. (Maximum of 3.) All of the examples I have seen, use the name attribute of each element. What I'd like to do is use the class instead, and then declare a rule for that. html This works: <input class="checkBox" type="checkbox" id="i0000zxthy" name="salutation" value="1" /> This doesn't work, but is what I'm aiming for: <input class="checkBox" type="checkbox" id="i0000zxthy" name="i0000zxthy" value="1" /> javascript: var validator = $(".formToValidate").validate({ rules:{ "salutation":{ required:true, }, "checkBox":{ required:true, minlength:3 } } }); Is it possible to do this - is there a way of targeting the class instead of the name within the rules options? Or do I have to add a custom method? Cheers, Matt

  • How to use > in an xargs command?

    - by jesse
    I want to find a bash command that will let me grep every file in a directory and write the output of that grep to a separate file. My guess would have been to do something like this ls -1 | xargs -I{} "grep ABC '{}' > '{}'.out" but, as far as I know, xargs doesn't like the double-quotes. If I remove the double-quotes, however, then the command redirects the output of the entire command to a single file called '{}'.out instead of to a series of individual files. Does anyone know of a way to do this using xargs? I just used this grep scenario as an example to illustrate my problem with xargs so any solutions that don't use xargs aren't as applicable for me.

  • String.fromCharCode & CharacterSets

    - by jAndy
    Hi Folks, I recently tried to mirror some input within input(text) fields. Using String.fromCharCode(event.which) for instance, translates all 'standard' characters correctly. Well it translates them all to uppercase, but that you can easily catch by looking up the shift key aswell. My Problem is, it can't translate characters like dots, commas, questionmarks etc. First guess was that I have to define a character encoding set, but that does not seem to help. Maybe it'm completly off? Kind Regards --Andy

  • Possible to add javascript to Zend_Form_Element_Radio?

    Ultimately, I'd like my Zend Form to render this HTML: <p>Do you have any documents to upload?</p> <p>Yes <input type="radio" value="Yes" name="uploadChoice" onClick="showTable()">&nbsp;&nbsp;No <input type="radio" value="No" name="uploadChoice" onClick="hideTable()" checked></p> Here's what I have in my Zend_Form: //create radio buttons $uploadQuestion = new Zend_Form_Element_Radio('upLoadQuestion'); $uploadQuestion->setLabel('Do you have any documents to upload?') ->addMultiOptions(array( 'yes' => 'Yes', 'no' => 'No' )) ->setSeparator(' '); The problem I'm running into is how to add the onClick="showTable()" and onClick="hideTable()" elements to their respective radio buttons. In the alternative, I could rework the javascript and add something like onClick="toggleTable()" to the radio buttons if I can't add something different to each of the radio buttons. But, will Zend let me do that?
