• Setting up Apache directory root behavior

  - by Corey

  I'm running Apache on a Windows machine for local testing and I'm new to it. Currently, if I navigate to localhost/ in a web browser, it will display an index.html page if one exists. Otherwise, it will display the directory listing. How can I make it so that navigating to a root directory will display more than index.html? What I need is so that if either: index.html, index.htm, or index.php exist, it will navigate to one of those. How can I disable showing directory roots? I would like it to return a 403 Forbidden error if no index page exists.

• Help with DB Structure, vOD site

  - by Chud37

  I have a video on demand style site that hosts series of videos under different modules. However with the way I have designed the database it is proving to be very slow. I have asked this question before and someone suggested indexing, but i cannot seem to get my head around it. But I would like someone to help with the structure of the database here to see if it can be improved. The core table is Videos: ID bigint(20) (primary key, auto-increment) pID text airdate text title text subject mediumtext url mediumtext mID int(11) vID int(11) sID int(11) pID is a unique 5 digit string to each video that is a shorthand identifier. Airdate is the TS, (stored in text format, right there maybe I should change that to TIMESTAMP AUTO UPDATE), title is self explanatory, subject is self explanatory, url is the hard link on the site to the video, mID is joined to another table for the module title, vID is joined to another table for the language of the video, (english, russian, etc) and sID is the summary for the module, a paragraph stored in an external database. The slowest part of the website is the logging part of it. I store the data in another table called 'Hits': id mediumint(10) (primary key, auto-increment) progID text ts int(10) Again, here (this was all made a while ago) but my Timestamp (ts) is an INT instead of ON UPDATE CURRENT TIMESTAMP, which I guess it should be. However This table is now 47,492 rows long and the script that I wrote to process it is very very slow, so slow in fact that it times out. A row is added to this table each time a user clicks 'Play' on the website and then so the progID is the same as the pID, and it logs the php time() timestamp in ts. Basically I load the entire database of 'Hits' into an array and count the hits in each day using the TS column. I am guessing (i'm quite slow at all this, but I had no idea this would happen when I built the thing) that this is possibly the worst way to go about this. So my questions are as follows: Is there a better way of structuring the 'Videos' table, is so, what do you suggest? Is there a better way of structuring 'hits', if so, please help/tell me! Or is it the fact that my tables are fine and the PHP coding is crappy?

• A look at an example of anti-spam algorithm

  - by pragmaticCamel

  What is a good approach to an anti-spam algorithm for a website similar to reddit? Their anti-spam algorithm seems awfully broken (banning on words in the title and doing a horrible job for that matter). Considering a post spam because it has the word 'spam' in the title is really not a wise choice. Anyway, how can one approach such problem ? Are there any tools that help in such cases? Also, what are the /technical/ reasons behind reddit's choice not using reCAPTCHA on every post submission? It seems like a much better solution than what they have right now. Since reddit is basically a community-driven website why not give such power to the communities' trusted members?

• NGINX Document Location

  - by GLaDOS

  I want to be able to access a given url, example.com/str. The problem is that the php file that I want to connect to is in a directory of /str/public/. In my nginx logs, I see that it is trying to connect to /str/public/str/index.php. Is there any way to remove that last 'str' in the document request? Below is my location directive in sites-available/default: location /str { root /usr/share/nginx/html/str/public/; index index.php index.html index.htm; location ~ ^/str/(.+\.php)$ { try_files $uri = 404; root /usr/share/nginx/html/str/public/; fastcgi_pass unix:/var/run/php5-fpm.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } } Thank you all so much in advance.

• help me being the next zuckerberg [closed]

  - by Kraken

  I really expect someone to help me with my problem as stated below. I started learning website making by having tutorials from w3schools.com but after doing taking the HTML tutorials I don't think I really can do anything with it. Maybe I don't know everything about HTML yet. I know the online tutorials are not enough but what I need you guys to tell me is that how can I learn making some nice websites. I have vacations for two months now and I think it would be the best time for me to learn making websites as I really love to be a website developer. Now I would like to start from the scratch. I know some C language (though I know it will not help me). So tell me from where shall I learn HTML and what all things shall I learn after that and in what order. If you can also help me with the material (let it be books or online tutorials). But I would like to know how can I gain confidence that I can make some websites as just learning online tutorials doesn't help me much. I also tried some video tutorials but in that too, they will just tell me some of the functions and not all. So what am I supposed to do.. just know a limited functions as they want me to know in video tutorials or do something else.

• google chrome window resizes when click 12.04 kde

  - by user37805

  All windows work fine but maximized G. Chrome window starts moving whenever I click under title bar without moving the cursor, but I don't want to move the windows, just to focus. Under the title bar is next to the tabs, on the blue part. This is annoying. It goes from maximized to moving windows function, with the cross instead of the pointer, only with single steady click. Using KDE 4.8.4, kubuntu 12.04. Something like this http://code.google.com/p/chromium/issues/detail?id=37013. How to solve this?

• Simple jquery ajax call leaks memory in ie.

  - by Thomas Lane

  I created a web page that makes an ajax call every second. In Internet Explorer 7, it leaks memory badly (20MB in about 15 minutes). The program is very simple. It just runs a javascript function that makes an ajax call. The server returns an empty string, and the javascript does nothing with it. I use setTimout to run the function every second, and I'm using Drip to watch the thing. Here is the source: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout('testJunk()',1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){} }); setTimeout('testJunk()',1000) } </script> </head> <body> Why is memory usage going up? </body> </html> Anyone have an idea how to plug this leak? I have a real application that updates a large table this way, but left unattended will eat up Gigabytes of memory. Okay, so after some good suggestions, I modified the code to: <html> <head> <script type="text/javascript" src="http://www.google.com/jsapi"></script> <script type="text/javascript"> google.load('jquery', '1.4.2'); google.load('jqueryui', '1.7.2'); </script> <script type="text/javascript"> setTimeout(testJunk,1000); function testJunk() { $.ajax({ url: 'http://xxxxxxxxxxxxxx/test', // The url returns an empty string dataType: 'html', success: function(data){setTimeout(testJunk,1000)} }); } </script> </head> <body> Why is memory usage going up? </body> </html> It didn't seem to make any difference though. I'm not doing anything with the DOM, and if I comment out the ajax call, the memory leak stops. So it looks like the leak is entirely in the ajax call. Does jquery ajax inherently create some sort of circular reference, and if so, how can I free it? By the way, it doesn't leak in Firefox. Someone suggested running the test in another VM and see if the results are the same. Rather than setting up another VM, I found a laptop that was running XP Home with IE8. It exhibits the same problem. I tried some older versions of jquery and got better results, but the problem didn't go away entirely until I abandoned ajax in jquery and went with more traditional (and ugly) ajax.

• Python unicode Decode Error SUDs

  - by PylonsN00b

  OK so I have # -*- coding: utf-8 -*- at the top of my script and it worked for being able to pull data from the database that had funny chars(Ñ ,Õ,é,—,–,’,…) in it and store that data into variables...but I have run into other problems, see I pull my data, organize it, and then dump it into a variables like so: title = product[1] Where product[1] is from my database result set Then I load it up for Suds like so: array_of_inventory_item_submit = ca_client_inventory.factory.create('ArrayOfInventoryItemSubmit') for product in products: inventory_item_submit = ca_client_inventory.factory.create('InventoryItemSubmit') inventory_item_list = get_item_list(product) inventory_item_submit = [inventory_item_list] array_of_inventory_item_submit.InventoryItemSubmit.append(inventory_item_submit) #Call that service baby! ca_client_inventory.service.SynchInventoryItemList(accountID, array_of_inventory_item_submit) Where get_item_list sets product[1] to title and (including a whole bunch of other nodes): inventory_item_submit.Title = title So everything runs fine until I call ca_client_inventory.service.SynchInventoryItemList that contains array_of_inventory_item_submit which contains the title w/ the funky char...here is the error: Traceback (most recent call last): File "upload_all_inventory_ebay.py", line 421, in <module> ca_client_inventory.service.SynchInventoryItemList(accountID, array_of_inventory_item_submit) File "build/bdist.macosx-10.6-i386/egg/suds/client.py", line 539, in __call__ File "build/bdist.macosx-10.6-i386/egg/suds/client.py", line 592, in invoke File "build/bdist.macosx-10.6-i386/egg/suds/bindings/binding.py", line 118, in get_message File "build/bdist.macosx-10.6-i386/egg/suds/bindings/document.py", line 63, in bodycontent File "build/bdist.macosx-10.6-i386/egg/suds/bindings/document.py", line 105, in mkparam File "build/bdist.macosx-10.6-i386/egg/suds/bindings/binding.py", line 260, in mkparam File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 62, in process File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 243, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 298, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 298, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 243, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 182, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/core.py", line 75, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 102, in append File "build/bdist.macosx-10.6-i386/egg/suds/mx/appender.py", line 198, in append File "build/bdist.macosx-10.6-i386/egg/suds/sax/element.py", line 251, in setText File "build/bdist.macosx-10.6-i386/egg/suds/sax/text.py", line 43, in __new__ UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 116: ordinal not in range(128) Now what? My guess is my script can take in these funky chars because I have # -*- coding: utf-8 -*- at the top but Suds does NOT have that at the top of its files. Do I really want to go and change the Suds files...we all know this is the least desired last possible solution...what can I do?

• Debugging matchit plugin in vim (under Cygwin)

  - by system PAUSE

  The "matchit" plugin for vim is supposed to allow you to use the % key to jump between matching start/end tags when editing HTML, as well as /* and */ comment delimiters when editing other kinds of code. I've followed the exact instructions in ":help matchit", but % still doesn't work for me. It seems silly to ask "Why doesn't this work?" so instead I'm asking How can I diagnose the problem? Pointers to references are welcome, but specific vim-plugin-debugging techniques are preferred.

• ASP.NET MVC jquery.UI dialog - How to validate the dialog's input on server and return error?

  - by Rick

  I am using jQuery1.4.2, ASP.NET MVC 2 and jQuery.UI-1.8. I am creating a data input dialog which works OK when all the data is valid, but I want to validate the input data on the server and return an error to the dialog describing the error and I am not quite sure how to do that and keep the dialog open. The dialog is opened when a link is clicked. The solution may be to try to bypass more of the MVC framework's default binding that handles the submit button clicks and creates the expected ProfilePermission object and calls the Controller's AddPermission POST Action method, but I was hoping there may be an easier way without have to write more jquery/javascript code to handle the button clicks and pass the data to the server. My script code looks like $("#dialog").dialog({ modal: true, position: ['center', 180], width: 500, height: 130, autoOpen: false }); $(".addPermissionDialog").click(function (event) { event.preventDefault(); $("#dialog").dialog('open'); return false; }); My View <div id="dialog" title="Add Permission"> <%: Html.ValidationSummary("") %> <% using (Html.BeginForm("AddPermission", "Profile")) { %> <%: Html.Hidden("PersonId") %> <%: Html.Hidden("ProfileId") %> <div class="editor-label"> <label for="PersonName">User Name:</label> <%: Html.TextBox("PersonName")%> <label for="PermissionType">Permission:</label> <select name="PermissionTypeId" id="PermissionTypeId" > <option value="2">Edit</option> <option value="3">View</option> </select> </div> <br /> <p> <input type="submit" name="saveButton" value="Add Permission" /> <input type="submit" id="cancelButton" name="cancelButton" value="Cancel" /> <script type="text/javascript"> document.getElementById("cancelButton").disableValidation = true; </script> </p> <% } %> </div> <br /> <p> <%: Html.ActionLink("Add Permission", "AddPermission", new { profileId = Model.First().ProfileId }, new { @class = "addPermissionDialog" })%> </p> My Controller action [AcceptVerbs("Post")] [HandleError] public ActionResult AddPermission(string cancelButton, ProfilePermission profilePermission) { ViewData["Controller"] = controllerName; ViewData["CurrentCategory"] = "AddPermission"; ViewData["ProfileId"] = profilePermission.ProfileId; PermissionTypes permission = repository.GetAccessRights(profilePermission.ProfileId); if (permission == PermissionTypes.View || permission == PermissionTypes.None) { ViewData["Message"] = "You do not have access rights (Edit or Owner permissions) to this profile"; return View("Error"); } // If cancel return to previous page if (cancelButton != null) { return RedirectToAction("ManagePermissions", new { profileId = profilePermission.ProfileId }); } if (ModelState.IsValid) { repository.SavePermission(profilePermission); return RedirectToAction("ManagePermissions", new { profileId = profilePermission.ProfileId }); } // IF YOU GET HERE THERE WAS AN ERROR return PartialView(profilePermission); // The desire is to redisplay the dialog with error message }

• Perl CGI that sends a temporary loading page to client then later sends the actual results page

  - by Kurt W. Leucht

  I've wasted at least a half day of my company's time searching the Internet for an answer and I'm getting wrapped around the axle here. I can't figure out the difference between all the different technology choices (long polling, ajax streaming, comet, XMPP, etc.) and I can't get a simple hello world example working on my PC. I am running Apache 2.2 and ActivePerl 5.10.0. JavaScript is completely acceptable for this solution. All I want to do is write a simple Perl CGI script that when accessed, it immediately returns some HTML that tells the user to wait or maybe sends an animated GIF. Then without any user intervention (no mouse clicks or anything) I want the CGI script to at some time later replace the wait message or the animated GIF with the actual HTML results from their query. I know this is simple stuff and websites do it all the time, but I can't find a single working example that I can cut and paste onto my machine that will work. Here is my simple Hello World example that I've compiled from various Internet sources, but it doesn't seem to work. When I refresh this CGI URL in my web browser it prints nothing for 5 seconds, then it prints the PLEASE BE PATIENT web page, but not the results web page. What am I doing wrong? #!C:\Perl\bin\perl.exe use CGI; use CGI::Carp qw/fatalsToBrowser warningsToBrowser/; sub Create_HTML { my $html = <<EOHTML; <html> <head> <meta http-equiv="pragma" content="no-cache" /> <meta http-equiv="expires" content="-1" /> <script type="text/javascript" > var xmlhttp=false; /*@cc_on @*/ /*@if (@_jscript_version >= 5) // JScript gives us Conditional compilation, we can cope with old IE versions. // and security blocked creation of the objects. try { xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); } catch (E) { xmlhttp = false; } } @end @*/ if (!xmlhttp && typeof XMLHttpRequest!='undefined') { try { xmlhttp = new XMLHttpRequest(); } catch (e) { xmlhttp=false; } } if (!xmlhttp && window.createRequest) { try { xmlhttp = window.createRequest(); } catch (e) { xmlhttp=false; } } </script> <title>Ajax Streaming Connection Demo</title> </head> <body> Some header text. <p> <div id="response">PLEASE BE PATIENT</div> <p> Some footer text. </body> </html> EOHTML return $html; } my $cgi = new CGI; print $cgi->header; print Create_HTML(); sleep(5); print "<script type=\"text/javascript\">\n"; print "\$('response').innerHTML = 'Here are your results!';\n"; print "</script>\n";

• Validation Summary for Lists using Data Annotations with MVC

  - by David Liddle

  I currently use a custom method to display validation error messages for lists but would like to replace this system for using with Data Annotations. In summary on validation of my form, I want to display "*" next to each input that is incorrect and also provide a Validation Summary at the bottom that relates each error message to the particular item in the list. e.g. say if validation failed on the 2nd list item on a Name input box and the 4th item on an Address input box the validation summary would display [2] Name is invalid [4] Address is invalid Please ignore if there are mistakes in the code below. I'm just writing this as an example. The code below shows how I was able to do it using my custom version of adding model errors but was wondering how to do this using Data Annotations? //Domain Object public class MyObject { public int ID { get; set; } public string Name { get; set; } public string Address { get; set; } public bool IsValid { get { return (GetRuleViolations().Count() == 0); } } public void IEnumerable<RuleViolation> GetRuleViolations() { if (String.IsNullOrEmpty(Name)) yield return new RuleViolation(ID, "Name", "Name is invalid"); if (String.IsNullOrEmpty(Address)) yield return new RuleViolation(ID, "Address", "Address is invalid"); yield break; } } //Rule Violation public class RuleViolation { public int ID { get; private set; } public string PropertyName { get; private set; } public string ErrorMessage { get; private set; } } //View <% for (int i = 0; i < 5; i++) { %> <p> <%= Html.Hidden("myObjects[" + i + "].ID", i) %> Name: <%= Html.TextBox("myObjects[" + i + "].Name") %> <br /> <%= Html.ValidationMessage("myObjects[" + i + "].Name", "*")<br /> Address: <%= Html.TextBox("myObjects[" + i + "].Address") %> <%= Html.ValidationMessage("myObjects[" + i + "].Address", "*")<br /> </p> <% } %> <p><%= Html.ValidationSummary() %> //Controller public ActionResult MyAction(IList<MyObject> myObjects) { foreach (MyObject o in myObjects) { if (!o.IsValid) ModelState.AddModelErrors(o.GetRuleViolations(), o.GetType().Name); } if (!Model.IsValid) { return View(); } } public static class ModelStateExtensions { public static void AddModelError(this ModelStateDictionary modelState, RuleViolation issue, string name) { string key = String.Format("{0}[{1}].{2}", name, issue.ID, issue.PropertyName); string error = String.Format("[{0}] {1}", (issue.ID + 1), issue.ErrorMessage); //above line determines the [ID] ErrorMessage to be //displayed in the Validation Summary modelState.AddModelError(key, error); }

• "Access is denied" JavaScript error when trying to access the document object of a programmatically-

  - by Bungle

  I have project in which I need to create an <iframe> element using JavaScript and append it to the DOM. After that, I need to insert some content into the <iframe>. It's a widget that will be embedded in third-party websites. I don't set the "src" attribute of the <iframe> since I don't want to load a page; rather, it is used to isolate/sandbox the content that I insert into it so that I don't run into CSS or JavaScript conflicts with the parent page. I'm using JSONP to load some HTML content from a server and insert it in this <iframe>. I have this working fine, with one serious exception - if the document.domain property is set in the parent page (which it may be in certain environments in which this widget is deployed), Internet Explorer (probably all versions, but I've confirmed in 6, 7, and 8) gives me an "Access is denied" error when I try to access the document object of this <iframe> I've created. It doesn't happen in any other browsers I've tested in (all major modern ones). This makes some sense, since I'm aware that Internet Explorer requires you to set the document.domain of all windows/frames that will communicate with each other to the same value. However, I'm not aware of any way to set this value on a document that I can't access. Is anyone aware of a way to do this - somehow set the document.domain property of this dynamically created <iframe>? Or am I not looking at it from the right angle - is there another way to achieve what I'm going for without running into this problem? I do need to use an <iframe> in any case, as the isolated/sandboxed window is crucial to the functionality of this widget. Here's my test code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <title>Document.domain Test</title> <script type="text/javascript"> document.domain = 'onespot.com'; // set the page's document.domain </script> </head> <body> <p>This is a paragraph above the &lt;iframe&gt;.</p> <div id="placeholder"></div> <p>This is a paragraph below the &lt;iframe&gt;.</p> <script type="text/javascript"> var iframe = document.createElement('iframe'), doc; // create <iframe> element document.getElementById('placeholder').appendChild(iframe); // append <iframe> element to the placeholder element setTimeout(function() { // set a timeout to give browsers a chance to recognize the <iframe> doc = iframe.contentWindow || iframe.contentDocument; // get a handle on the <iframe> document alert(doc); if (doc.document) { // HEREIN LIES THE PROBLEM doc = doc.document; } doc.body.innerHTML = '<h1>Hello!</h1>'; // add an element }, 10); </script> </body> </html> I've hosted it at: http://troy.onespot.com/static/access_denied.html As you'll see if you load this page in IE, at the point that I call alert(), I do have a handle on the window object of the <iframe>; I just can't get any deeper, into its document object. Thanks very much for any help or suggestions! I'll be indebted to whomever can help me find a solution to this.

• On REST: WADL or not IDL, is the following approach right ?

  - by redben

  This question is a bit long, please bear with me. In REST, i think we should not need WADL or any IDL. But rather something that would implicitly cover its concept. The way I think about it is when we (humans) surf the Web, when we go to a web site for the first time, we don't know what services it provides. You discover those on the html home page (or a sitemap page in a help section) or maybe just the main menu on the home page. If you make an analogy, the homepage or site map to us humans is what WSDL is to WS-* or what WADL could be to a REST service. Only that its just like any other html content. I think that in REST the following is a good way to do things, respecting the HATEOS paradigm. Have a top level (or default) resource that lists links to your other resources. For a library example, say RestLibrary.com/ it could be something like: <root xmlns:lib="http://librarystandards.com/libraryml"> <resource class="lib:book"> <link type="application/vnd.libraryml+xml" template="mylib.com/book/{isbn}" /> <link type="application/vnd.libraryml+xml" rel="add" href="mylib.com/book" method="POST" /> <link type="application/vnd.libraryml+xml" rel="update" template="mylib.com/book/{isbn}" method="PUT" /> </resource> <resource class="lib:bookList"> <link template="mylib.com/book?keywords={keywords}" type="application/vnd.openlibrary+xml" rel="search" /> </resource> </root> Note that it is assumed that the media type "application/vnd.libraryml+xml" is a defined standard or (may be just proprietary vocabulary) named libraryml. Also, the client should be able to understand this "homepage" resource (elements root, resource and link). This is the part that could be used instead of WADL : an Abstract vocabulary that should be understandable by any client. You could use an existing standard like Atom for example. But the main idea is to have an abstract vocabulary understandable by any client. Why not WADL then ? well wadl is only for service discovery. The idea here is to have an light abstract vocabulary that would serve as a base for hypermedia. A "root" vocabulary. Like in owl we have owl:thing...etc Now if the client knows the "libraryml" standard it can follow the links to the things it understands (after parsing the media type properties and xmlns). If not, it just won't. When i can't understand how to deal with something in REST architecture i tend to see how we Humans do it in the Web. In the Web, we have the Generic language that is HTML that enables site builders to deliver any specific content, regardless of its meaning to the client (the user), Browsers understand HTML but not the "meaning" of its content. It is the user that understands the (domain specific) content. If i go to say QuantumPhysics.org, my browser can render the home page (it is just html after all) and i can read the home page. If i understand quantum then fine i can continue browsing. If i don't i just get out (unless i want to learn the hardway :) ) In the RetsLibrary.com example the client app is just like me+my browser on QuantumPhysics.org. the media type "application/vnd.libraryml+xml" is quantum physics (knowledge). http is http in both examples. Now HTML of QuantumPhysics.org is in RestLibrary.com is XML + that tiny little abstract vocabulary (root resource and link, that you could replace with something like Atom). So does this approach have any value ? don't we need a root tiny hyper-vocabulary so we can succeed with hypermedia and the "initial URI" concept ? edit Yeah why not RDF as the root vocabulary !

• ASP.NET resseting SessionID cookie when cookie expiration date is set

  - by Sergej Andrejev

  I have two pages: Default.aspx and WebForm1.aspx. One of these pages stores a session variable which works fine until I add code which ads expiration date to SessionID cookie. What happens is: Open default.aspx Set-Cookie ASP.NET_SessionId=14jhsdfq23jkh13jkh12k1; expires=Fri, 19-Mar-2010 07:31:47 GMT; path=/ Click on link to open WebForm1.aspx No cookies set Click on link to open Default.aspx (Cookie is reset) Set-Cookie ASP.NET_SessionId=; expires=Fri, 19-Mar-2010 07:31:47 GMT; path=/ So the question would be how should I set SessionID cookie expiration date correctly? Default.aspx.cs using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication1 { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { lnk.Click += new EventHandler(lnk_Click); Session["t"] = Guid.NewGuid(); Response.Cookies["ASP.NET_SessionId"].Expires = DateTime.Now.AddDays(2); } void lnk_Click(object sender, EventArgs e) { Response.Redirect("WebForm1.aspx"); } } } Default.aspx <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication1._Default" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:LinkButton runat="server" ID="lnk" Text=">>>" /> </div> </form> </body> </html> WebForm1.aspx.cs using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication1 { public partial class WebForm1 : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { lnk.Click += new EventHandler(lnk_Click); } void lnk_Click(object sender, EventArgs e) { Response.Redirect("Default.aspx"); } } } WebForm1.aspx <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication1.WebForm1" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" > <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> <asp:LinkButton runat="server" ID="lnk" Text=">>>" /> </div> </form> </body> </html>

Please could someone help me in constructing a proper unordered list based on my depth,itemid coulumns? Thanks.

• JS: using 'var me = this' to reference an object instead of using a global array

  The example below, is just an example, I know that I don't need an object to show an alert box when user clicks on div blocks, but it's just a simple example to explain a situation that frequently happens when writing JS code. In the example below I use a globally visible array of objects to keep a reference to each new created HelloObject, in this way events called when clicking on a div block can use the reference in the arry to call the HelloObject's public function hello(). 1st have a look at the code: <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html><head><meta http-equiv="Content-Type" content="text/html; charset=windows-1252"> <title>Test </title> <script type="text/javascript"> /***************************************************** Just a cross browser append event function, don't need to understand this one to answer my question *****************************************************/ function AppendEvent(html_element, event_name, event_function) {if(html_element) {if(html_element.attachEvent) html_element.attachEvent("on" + event_name, event_function); else if(html_element.addEventListener) html_element.addEventListener(event_name, event_function, false); }} /****************************************************** Just a test object ******************************************************/ var helloobjs = []; var HelloObject = function HelloObject(div_container) { //Adding this object in helloobjs array var id = helloobjs.length; helloobjs[id] = this; //Appending click event to show the hello window AppendEvent(div_container, 'click', function() { helloobjs[id].hello(); //THIS WORKS! }); /***************************************************/ this.hello = function() { alert('hello'); } } </script> </head><body> <div id="one">click me</div> <div id="two">click me</div> <script type="text/javascript"> var t = new HelloObject(document.getElementById('one')); var t = new HelloObject(document.getElementById('two')); </script> </body></html> In order to achive the same result I could simply replace the code //Appending click event to show the hello window AppendEvent(div_container, 'click', function() { helloobjs[id].hello(); //THIS WORKS! }); with this code: //Appending click event to show the hello window var me = this; AppendEvent(div_container, 'click', function() { me.hello(); //THIS WORKS TOO AND THE GLOBAL helloobjs ARRAY BECOMES SUPEFLOUS! }); thus would make the helloobjs array superflous. My question is: does this 2nd option in your opinion create memoy leaks on IE or strange cicular references that might lead to browsers going slow or to break??? I don't know how to explain, but coming from a background as a C/C++ coder, doing in this 2nd way sounds like a some sort of circular reference that might break memory at some point. I also read on internet about the IE closures memory leak issue http://jibbering.com/faq/faq_notes/closures.html (I don't know if it was fixed in IE7 and if yes, I hope it does not come out again in IE8). Thanks
