  • Is there a simpler way to convert a byte array to a 2-byte-size hexadecimal string?

    - by Tom Brito
    Is there a simpler way of implement this? Or a implemented method in JDK or other lib? /** * Convert a byte array to 2-byte-size hexadecimal String. */ public static String to2DigitsHex(byte[] bytes) { String hexData = ""; for (int i = 0; i < bytes.length; i++) { int intV = bytes[i] & 0xFF; // positive int String hexV = Integer.toHexString(intV); if (hexV.length() < 2) { hexV = "0" + hexV; } hexData += hexV; } return hexData; } public static void main(String[] args) { System.out.println(to2DigitsHex(new byte[] {8, 10, 12})); } the output is: "08 0A 0C" (without the spaces)

  • Mapping Hilbert values to 3D points

    - by Alexander Gladysh
    I have a set of Hilbert values (length from the start of the Hilbert curve to the given point). What is the best way to convert these values to 3D points? Original Hilbert curve was not in 3D, so I guess I have to pick by myself the Hilbert curve rank I need. I do have total curve length though (that is, the maximum value in the set). Perhaps there is an existing implementation? Some library that would allow me to work with Hilbert curve / values? Language does not matter much.

  • I am totally unable to add a fileTree (JQuery fileTree addon) to my asp.net page

    - by Gadgetsan
    okay, so i have an asp.net (C#) application and i want to add a list of file and folders on the page, so i figured i should use JQuery fileTree (http://abeautifulsite.net/2008/03/jquery-file-tree/#download) but now i am totally unable to display the file list. I initialise the page this way: Site.Master: <link rel="stylesheet" type="text/css" href="../../Content/superfish.css" media="screen"> <link href="../../Content/jqueryFileTree.css" rel="stylesheet" type="text/css" /> <script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> <script src="../../Scripts/jquery.easing.1.3.js" type="text/javascript"></script> <script src="../../Scripts/jqueryFileTree.js" type="text/javascript"></script> <script src="../../Scripts/JqueryUI/js/jquery-ui-1.8.1.custom.min.js" type="text/javascript"></script> <script type="text/javascript" src="../../Scripts/jquery.dataTables.js"></script> <script type="text/javascript" src="../../Scripts/superfish.js"></script> <script type="text/javascript"> $(document).ready(function() { test = $('#fileTree').fileTree({script: "jqueryFileTree.aspx" }, function(file) { openFile(file); }); $("button").button(); oTable = $('#data').dataTable({ "bJQueryUI": true, "sPaginationType": "full_numbers", "bSort": true }); }); </script> and in the page, i put my div this way: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> Documents but i'm positive that jqueryFileTree.aspx is never "called" because if i return this page in my controller, it shows the list of files/folder correctly, so it's also not a problem with my aspx connector... Also i checked, on the JS console, it gives no error and there is nothing more in the page source code i've been trying to solve this all day without success so your help is apreciated

  • Change DIV background color for all inputs in form

    - by Erik
    I have a form with 20 input fields. Each input field is inside a DIV I have a script that changes the background color of the DIV via keyup function along with two other DIV tags. Rather than duplicating the script 20 times for each DIV and Input, is it possible to re-write the script to do all DIV's and their Inputs? <script> $(document).ready(function(){ $("#id").keyup(function() { if($("#id").val().length > 0) $("#in1, #nu1, #lw1, #id").css("background-color", "#2F2F2F").css("color", "#FFF"); else { if($("#id").val().length == 0) $("#in1, #nu1, #lw1, #id").css("background-color", "#E8E8E8").css("color", "#000"); } }); }); </script>

  • How to remove not required Elements from generated XML via jaxb

    - by Dangling Piyush
    I want to know if there is anyway for removing not required elements from generated xml using jaxb.I have my xsd element definition as follows. <xsd:element name="Title" maxOccurs="1" minOccurs="0"> <xsd:annotation> <xsd:documentation> A name given to the digital record. </xsd:documentation> </xsd:annotation> <xsd:simpleType> <xsd:restriction base="xsd:string"> <xsd:minLength value="1"></xsd:minLength> </xsd:restriction> </xsd:simpleType> </xsd:element> As you can see it is not a mandatory element because minOccurs="0" But if it is not empty the length should be 1. <xsd:minLength value="1"></xsd:minLength> At the time of marshalling if I left the Title field blank it is throwing the SAXException because of min-length restriction. So what I want to do is to remove the whole occurrence of <Title/> from generated XML.Right now i have removed the min-length restriction so it is adding the <Title> element as EMPTY <Title></Title> But I do not want it like this.Any help is appreciated.I am using jaxb 2.0 for Marshalling. UPDATE: Following is my variable definiton : private JAXBContext jaxbContext; private Unmarshaller unmarshaller; private SchemaFactory factory; private Schema schema; private Marshaller marshaller; Marshalling code. jaxbContext = JAXBContext.newInstance(ERecordType.class); marshaller = jaxbContext.createMarshaller(); factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); schema = factory.newSchema((new File(xsdLocation))); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); ERecordType e = new ERecordType(); e.setCataloging(rc); /** * Validate Against Schema. */ marshaller.setSchema(schema); /** * Marshal will throw an exception if XML not validated against * schema. */ marshaller.marshal(e, System.out);

  • What should the standard be for ReSTful URLS?

    - by gargantaun
    Since I can't find a chuffing job, I've been reading up on ReST and creating web services. The way I've interpreted it, the future is all about creating a web service for all your data before you build the web app. Which seems like a good idea. However, there seems to be a lot of contradictory thoughts on what the best scheme is for ReSTful URLs. Some people advocate simple pretty urls http://api.myapp.com/resource/1 In addition, some people like to add the API version to the url like so http://api.myapp.com/v1/resource/1 And to make things even more confusing, some people advocate adding the content-type to get requests http://api.myapp.com/v1/resource/1.xml http://api.myapp.com/v1/resource/1.json http://api.myapp.com/v1/resource/1.txt Whereas others think the content-type should be sent in the HTTP header. Soooooooo.... That's a lot of variation, which has left me unsure of what the best URL scheme is. I personally see the merits of the most comprehensive URL that includes a version number, resource locator and content-type, but I'm new to this so I could be wrong. On the other hand, you could argue that you should do "whatever works best for you". But that doesn't really fit with the ReST mentality as far as I can tell since the aim is to have a standard. And since a lot of you people will have more experience than me with ReST, I thought I'd ask for some guidance. So, with all that in mind... What should the standard be for ReSTful URLS?

  • Passing IDisposable objects through constructor chains

    - by Matt Enright
    I've got a small hierarchy of objects that in general gets constructed from data in a Stream, but for some particular subclasses, can be synthesized from a simpler argument list. In chaining the constructors from the subclasses, I'm running into an issue with ensuring the disposal of the synthesized stream that the base class constructor needs. Its not escaped me that the use of IDisposable objects this way is possibly just dirty pool (plz advise?) for reasons I've not considered, but, this issue aside, it seems fairly straightforward (and good encapsulation). Codes: abstract class Node { protected Node (Stream raw) { // calculate/generate some base class properties } } class FilesystemNode : Node { public FilesystemNode (FileStream fs) : base (fs) { // all good here; disposing of fs not our responsibility } } class CompositeNode : Node { public CompositeNode (IEnumerable some_stuff) : base (GenerateRaw (some_stuff)) { // rogue stream from GenerateRaw now loose in the wild! } static Stream GenerateRaw (IEnumerable some_stuff) { var content = new MemoryStream (); // molest elements of some_stuff into proper format, write to stream content.Seek (0, SeekOrigin.Begin); return content; } } I realize that not disposing of a MemoryStream is not exactly a world-stopping case of bad CLR citizenship, but it still gives me the heebie-jeebies (not to mention that I may not always be using a MemoryStream for other subtypes). It's not in scope, so I can't explicitly Dispose () it later in the constructor, and adding a using statement in GenerateRaw () is self-defeating since I need the stream returned. Is there a better way to do this? Preemptive strikes: yes, the properties calculated in the Node constructor should be part of the base class, and should not be calculated by (or accessible in) the subclasses I won't require that a stream be passed into CompositeNode (its format should be irrelevant to the caller) The previous iteration had the value calculation in the base class as a separate protected method, which I then just called at the end of each subtype constructor, moved the body of GenerateRaw () into a using statement in the body of the CompositeNode constructor. But the repetition of requiring that call for each constructor and not being able to guarantee that it be run for every subtype ever (a Node is not a Node, semantically, without these properties initialized) gave me heebie-jeebies far worse than the (potential) resource leak here does.

  • Problem in finalizing the link list in C#

    - by Yasin
    My code was almost finished that a maddening bug came up! when i nullify the last node to finalize the link list , it actually dumps all the links and make the first node link Null ! when i trace it , its working totally fine creating the list in the loop but after the loop is done that happens and it destroys the rest of the link by doing so, and i don't understand why something so obvious is becoming problematic! (last line) struct poly { public int coef; public int pow; public poly* link;} ; poly* start ; poly* start2; poly* p; poly* second; poly* result; poly* ptr; poly* start3; poly* q; poly* q2; private void button1_Click(object sender, EventArgs e) { string holder = ""; IntPtr newP = Marshal.AllocHGlobal(sizeof(poly)); q = (poly*)newP.ToPointer(); start = q; int i = 0; while (this.textBox1.Text[i] != ',') { holder += this.textBox1.Text[i]; i++; } q->coef = int.Parse(holder); i++; holder = ""; while (this.textBox1.Text[i] != ';') { holder += this.textBox1.Text[i]; i++; } q->pow = int.Parse(holder); holder = ""; p = start; //creation of the first node finished! i++; for (; i < this.textBox1.Text.Length; i++) { newP = Marshal.AllocHGlobal(sizeof(poly)); poly* test = (poly*)newP.ToPointer(); while (this.textBox1.Text[i] != ',') { holder += this.textBox1.Text[i]; i++; } test->coef = int.Parse(holder); holder = ""; i++; while (this.textBox1.Text[i] != ';' && i < this.textBox1.Text.Length - 1) { holder += this.textBox1.Text[i]; if (i < this.textBox1.Text.Length - 1) i++; } test->pow = int.Parse(holder); holder = ""; p->link = test; //the addresses are correct and the list is complete } p->link = null; //only the first node exists now with a null link! }

  • Jquery problem - cant expand the row above in a table

    - by apg1985
    Hi People, What I cant figure out is how I would toggle a row in a table using the one below it. So say I have a table with 2 rows the first contains content and the one below contains a button, when the page loads the content row is hidden and when you click the button it toggles the content row on and off. In the example the first table works but the second does not, I need the second one to work. <!DOCTYPE HTML> <html> <head> <title>Testing Horizontal Accordion</title> <script type="text/javascript" src="jquery.js"></script> <script type="text/javascript"> $(document).ready(function() { $(".sectionhead").toggle( function() { $(this).next("tr").hide(); }, function() { $(this).next("tr").show(); } ) }); </script> </head> <body> <table> <tr class="sectionhead"><td></td></tr> <tr class="child"><td>child</td></tr> </table> <br> <table> <tr class="child"><td>child</td></tr> <tr class="sectionhead"><td></td></tr> </table> </body> </html>

  • How to make active services highly available?

    - by Jader Dias
    I know that with Network Load Balancing and Failover Clusteringwe can make passive services highly available. But what about active apps? Example: One of my apps retrieves some content from a external resource in a fixed interval. I have imagined the following scenarios: Run it in a single machine. Problem: if this instance falls, the content won't be retrieved Run it in each machine of the cluster. Problem: the content will be retrieved multiple times Have it in each machine of the cluster, but run it only in one of them. Each instance will have to check some sort of common resource to decide whether it its turn to do the task or not. When I was thinking about the solution #3 I have wondered what should be the common resource. I have thought of creating a table in the database, where we could use it to get a global lock. Is this the best solution? How does people usually do this? By the way it's a C# .NET WCF app running on Windows Server 2008

  • DocumentFragment not appending in IE

    - by bmwbzz
    I have a select list which, when changed, pulls data via ajax and dynamically creates select lists. Then based on the data used to create the select lists (a type), I pull more data via ajax if i don't have it already and create the options for the select list and store them in a fragment. Then I append that fragment to the select list. This is zippy in FF3 and Chrome but either doesn't append the options at all or takes a long time (minutes) to append the options in IE7. Note: I am also using jQuery. code from the success callback which creates the select lists: blockDiv.empty(); var contentItemTypes = new Array(); selectLists = new Array(); for (var post in msg) { if (post != undefined) { var div = fragment.cloneNode(true); //deep copy var nameDiv = $(div.firstChild); nameDiv.text(msg[post].Name); blockDiv[0].appendChild(div); var allSelectLists = blockDiv.find('.editor-field select'); var selectList = $(allSelectLists[allSelectLists.length - 1]); var blockId = msg[post].ID; var elId = 'PageContentItem.' + blockId; selectList.attr('id', elId); selectList.attr('name', elId); var contentItemTypeId = msg[post].ContentItemTypeId; selectList.attr('cit', contentItemTypeId); if (contentItems[contentItemTypeId] != null || contentItems[contentItemTypeId] != undefined) { contentItems[contentItemTypeId] = null; } selectLists[post] = selectList; } } var firstContentTypeId = selectLists[0].attr('cit'); getContentItems(firstContentTypeId, setContentItemsForList, 0); code to get the items for the options in the select lists. function getContentItems(contentTypeId, callback, callbackParam) { if (contentItems[contentTypeId] != null || contentItems[contentTypeId] != undefined) { callback(contentTypeId, callbackParam); return; } contentItems[contentTypeId] = document.createDocumentFragment(); Q.ajax({ type: "POST", url: "/CMS/ContentItem/ListByContentType/" + contentTypeId, data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", error: function(xhr, msg, e) { var err = eval("(" + xhr.responseText + ")"); alert(err.ExceptionType + " ***** " + err.Message + " ***** " + err.StackTrace); }, success: function(msg) { var li; for (var post in msg) { if (post != undefined) { li = $('<option value="' + msg[post].ID + '">' + msg[post].Description + '</option>'); contentItems[contentTypeId].appendChild(li[0]); } } callback(contentTypeId, callbackParam); } }); } function setContentItemsForList(contentTypeId, selectIndex) { if (selectIndex < selectLists.length) { var items = contentItems[contentTypeId].cloneNode(true); selectLists[selectIndex].append($(items.childNodes)); selectIndex++; if (selectIndex < selectLists.length) { var nextContentTypeId = selectLists[selectIndex].attr('cit'); getContentItems(nextContentTypeId, setContentItemsForList, selectIndex); } } }

  • How can I safely raise events in an AsyncCallback?

    - by cyclotis04
    I'm writing a wrapper class around a TcpClient which raises an event when data arrives. I'm using BeginRead and EndRead, but when the parent form handles the event, it's not running on the UI thread. I do I need to use delegates and pass the context into the callback? I thought that callbacks were a way to avoid this... void ReadCallback(IAsyncResult ar) { int length = _tcpClient.GetStream().EndRead(ar); _stringBuilder.Append(ByteArrayToString(_buffer, length)); BeginRead(); OnStringArrival(EventArgs.Empty); }

  • Trying to find a PHP5 API-based embeddable CMS

    - by StrangeElement
    I've been making the rounds for a CMS that I can use as an API, in a sort of "embedded" mode. I mean by this that I don't want the CMS to do any logic or presentation. I want it to be used as an API, which I can then use within an existing site. I don't want to be tied to the architecture of the CMS. A good example of this is NC-CMS (http://www.nconsulting.ca/nc-cms/). All it needs is an include at the top, then wherever editable content is desired it's only a function call with a unique label. It's also perfect in the sense that it allows to differentiate between small strings (like titles, labels) and texts (which require a rich-text editor). It's the only CMS I found that fits this description, but it is a little too light as it does not handle site structure. I need to be able to allow my client to add pages, choosing an existing template for the layout. A minimal back-end is required. Wordpress also fits some requirements in that it handles only content editing and allows freedom for the themes by letting them call the content where and how they want it. But it is article-based and backwards, in that it embeds sites (as themes) within its structure, rather than being embeddable in sites like NC. It's funny how checking out all the CMS out there, almost all of them claim that most CMS are not self-sufficient, that they do not handle application logic, while (almost) every single on I found with only one exception do so. Many are mostly article-based blog engines, which does not fit my need. I would appreciate any CMS that fits the general description.

  • Flash AS3 button eventlistener array bug

    - by Tyler Pepper
    Hi there, this is my first time posting a question here. I have an array of 12 buttons on a timeline that when first visiting that part of the timeline, get a CLICK eventlistener added to them using a for loop. All of them work perfectly at that point. When you click one it plays a frame label inside the specific movieClip and reveals a bio on the corresponding person with a close button and removes the CLICK eventlisteners for each button, again using a for loop. The close button plays a closing animation, and then the timeline goes back to the first frame (the one with the 12 buttons on it) and the CLICK eventlisteners are re-added, but now only the first 9 buttons of the array work. There are no output errors and the code to re-add the eventlisteners is exactly the same as the first time that works. I am completely at a loss and am wondering if anyone else has run into this problem. All of my buttons are named correctly, there are absolutely no output errors (I've used the debug module) and I made sure the array with the buttons in it is outputting all 12 at the moment the close button is clicked to add the eventlisteners back. for (var q = 0; q < ackBoDBtnArray.length; q++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[q]].addEventListener(MouseEvent.CLICK, showBio); } private function showBio(eo:MouseEvent):void { trace("show the bio"); bodVar = ackBoDBtnArray.getIndex(eo.target.name); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDPgArray[bodVar]); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.addEventListener(MouseEvent.CLICK, hideBio); for (var r = 0; r < ackBoDBtnArray.length; r++){ contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].mouseEnabled = false; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[r]].removeEventListener(MouseEvent.CLICK, showBio); } } private function hideBio(eo:MouseEvent):void { trace("hide it!"); contentArea_mc.acknowledgements_mc.BoD_mc.closeBio_btn.removeEventListener(MouseEvent.CLICK, hideBio); contentArea_mc.acknowledgements_mc.BoD_mc.gotoAndPlay(ackBoDClosePgArray[bodVar]); for (var s = 0; s < ackBoDBtnArray.length; s++){ trace(ackBoDBtnArray[s]); contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].mouseEnabled = true; contentArea_mc.acknowledgements_mc.BoD_mc[ackBoDBtnArray[s]].addEventListener(MouseEvent.CLICK, showBio); } Thanks in advance for any help and insight you can provide...I have a slight feeling that its something that may be obvious to another set of eyes...haha.

  • JQuery validation - how to set the title attribute to the error message

    - by JK
    In JQuery validation the default behavior on an error is to create a label like so: <label for="FirstName" generated="true" class="error">This field is required.</label> Is it possible to change it so that it will output this instead (with a title attribute set to the error message)? <label for="FirstName" generated="true" class="error" title="This field is required.">This field is required.</label> I've tried the highlight method, but the label has not been created yet: $("#form").validate({ highlight: function (element, errorClass) { var label = $("label[for=" + element.id + "]"); // but label doesn't exist yet so this doesnt work if (label && label.length > 0) { // label.length is always 0 label.attr('title', label.text()); } } });

  • How to get compatibility between C# and SQL2k8 AES Encryption?

    - by Victor Rodrigues
    I have an AES encryption being made on two columns: one of these columns is stored at a SQL Server 2000 database; the other is stored at a SQL Server 2008 database. As the first column's database (2000) doesn't have native functionality for encryption / decryption, we've decided to do the cryptography logic at application level, with .NET classes, for both. But as the second column's database (2008) allow this kind of functionality, we'd like to make the data migration using the database functions to be faster, since the data migration in SQL 2k is much smaller than this second and it will last more than 50 hours because of being made at application level. My problem started at this point: using the same key, I didn't achieve the same result when encrypting a value, neither the same result size. Below we have the full logic in both sides.. Of course I'm not showing the key, but everything else is the same: private byte[] RijndaelEncrypt(byte[] clearData, byte[] Key) { var memoryStream = new MemoryStream(); Rijndael algorithm = Rijndael.Create(); algorithm.Key = Key; algorithm.IV = InitializationVector; var criptoStream = new CryptoStream(memoryStream, algorithm.CreateEncryptor(), CryptoStreamMode.Write); criptoStream.Write(clearData, 0, clearData.Length); criptoStream.Close(); byte[] encryptedData = memoryStream.ToArray(); return encryptedData; } private byte[] RijndaelDecrypt(byte[] cipherData, byte[] Key) { var memoryStream = new MemoryStream(); Rijndael algorithm = Rijndael.Create(); algorithm.Key = Key; algorithm.IV = InitializationVector; var criptoStream = new CryptoStream(memoryStream, algorithm.CreateDecryptor(), CryptoStreamMode.Write); criptoStream.Write(cipherData, 0, cipherData.Length); criptoStream.Close(); byte[] decryptedData = memoryStream.ToArray(); return decryptedData; } This is the SQL Code sample: open symmetric key columnKey decryption by password = N'{pwd!!i_ll_not_show_it_here}' declare @enc varchar(max) set @enc = dbo.VarBinarytoBase64(EncryptByKey(Key_GUID('columnKey'), 'blablabla')) select LEN(@enc), @enc This varbinaryToBase64 is a tested sql function we use to convert varbinary to the same format we use to store strings in the .net application. The result in C# is: eg0wgTeR3noWYgvdmpzTKijkdtTsdvnvKzh+uhyN3Lo= The same result in SQL2k8 is: AI0zI7D77EmqgTQrdgMBHAEAAACyACXb+P3HvctA0yBduAuwPS4Ah3AB4Dbdj2KBGC1Dk4b8GEbtXs5fINzvusp8FRBknF15Br2xI1CqP0Qb/M4w I just didn't get yet what I'm doing wrong. Do you have any ideas? EDIT: One point I think is crucial: I have one Initialization Vector at my C# code, 16 bytes. This IV is not set at SQL symmetric key, could I do this? But even not filling the IV in C#, I get very different results, both in content and length.

  • Background-image won't change using jquery in IE6

    - by slav
    There is a panel on my page with no default background-image css. On load it is set with jquery to an initial image, waits for 10 seconds then loads a random image out of some predetermined images. There are previous and next buttons which allow you to cycle through the images. In ie6 the initial image loads and then a random image also loads after 10 seconds, however pressing prev/next causes the background to become white and the images aren't loaded. With alerts I was able to find that it's still keeping track of the position and url of the image it's supposed to load, but just won't load it. Here is the code below. <script type="text/javascript"> var facts = new Array(); var position; $(document).ready(function() { <xsl:for-each select="$currentPage/ancestor-or-self::node[@level=1]/../node[@nodeName='Fun Fact Folder']/node"> facts[<xsl:value-of select="position()" />] = '<xsl:value-of select="." />'; </xsl:for-each> if(window.location.pathname == "/homepage.aspx" || window.location.pathname == "/") { $(".fun_facts_bg").css("background-image", "url(images/fun_fact_homepage.JPG)"); setTimeout("randomFact()",10000); } else { randomFact(); } }); function randomFact() { $("a.previous_button").css("display", "block"); $("a.next_button").css("display", "block"); position = Math.ceil(Math.random() * (facts.length - 1)); changeFact(0); } function changeFact(increment) { position = checkPosition(position, increment); $(".fun_facts_bg").css("background-image", "url(" + facts[position] + ")"); } <xsl:text disable-output-escaping="yes">&lt;!--//--&gt;&lt;![CDATA[//&gt;&lt;!-- function checkPosition(currentPos, increment) { currentPos = currentPos + increment; if (currentPos &gt; facts.length - 1) { currentPos = 1; } else if (currentPos &lt; 1) { currentPos = facts.length - 1; } return currentPos; } //--&gt;&lt;!]]&gt;</xsl:text> </script> <a class="previous_button" href="javascript:void(0);" onclick="changeFact(-1);"> <a class="next_button" href="javascript:void(0);" onclick="changeFact(1);">

  • Ruby Built In Method to Create Multidimensional Array From Single Dimensioned Array

    - by Ell
    If I have an array like this: [0, 1, 2, 3, 4, 5], is there a built in method to create this: [[0, 1, 2], [3, 4, 5]] given a width of 3? If there is no built in method, how could I improve on this? def multi_to_single(array, width) return [].tap{|md_array| (array.length.to_f / width).ceil.times {|y| row = (array[(y*width), width]) md_array.push( row + Array.new(width - row.length)) } } end I feel like I have missed something obvious because I haven't programmed ruby in a while! Thanks in advance, ell. EDIT: It needs to be in the core library, so no ruby on rails or anything.

  • Javascript + Firebug : "cannot access optimized closure" What does it mean?

    - by interstar
    I just got the following error in a piece of javascript (in Firefox 3.5, with Firebug running) cannot access optimized closure I know, superficially, what caused the error. I had a line options.length() instead of options.length Fixing this bug, made the message go away. But I'm curious. What does this mean? What is an optimized closure? Is optimizing an enclosure something that the javascript interpretter does automatically? What does it do?

  • java get file paths

    - by user283188
    hey everybody, I have a jsp page which contains the code which prints all files in a given directory and their file paths. The code is if (dir.isDirectory()) { File[] dirs = dir.listFiles(); for (File f : dirs) { if (f.isDirectory() && !f.isHidden()) { File files[] = f.listFiles(); for (File d : files) { if (d.isFile() && !d.isHidden()) { System.out.println(d.getName()+ d.getParent() + (d.length()/1024)); } } } if (f.isFile() && !f.isHidden()) { System.out.println(f.getName()+ f.getParent() + (f.length()/1024)); } } } The problem is that it prints the complete file path, which when accessed from tomcat is invalid. For example, the code spits out the following path: /usr/local/tomcat/sites/web_tech/images/scores/blah.jpg and I want it to only print the path up to /images ie /images/scores/blah.jpg I know I could just mess around with an actual string, ie splitting it or string matching, but is there an easier way to do it? Thanks
