  • Will PHP Die In Web Page Development World?

    - by Morgan Cheng
    I know that PHP is still the most popular web programming language in the world. This question just want to bring some of my concerns about PHP. PHP is naturally bound to C10K problem. Since PHP (generally run in Apache) cannot be event-driven or asynchronous, each HTTP request will occupy at least one thread or process. This makes it resistant to be more scalable. Currently, a lot of web sites (like Facebook) with high performance and scalability still depends on PHP in their front end servers. I suppose it is due to legacy reason. Is it possible that PHP will be replaced by language more suitable for C10K?

  • C#: Why only integral enums?

    - by JamesBrownIsDead
    I've been writing C# for seven years now, and I keep wondering, why do enums have to be of an integral type? Wouldn't it be nice to do something like: enum ErrorMessage { NotFound: "Could not find", BadRequest: "Malformed request" } Is this a language design choice, or are there fundamental incompatibilities on a compiler, CLR, or IL level? Do other languages have enums with string or complex (i.e. object) types? What languages? (I'm aware of workarounds; my question is, why are they needed?) EDIT: "workarounds" = attributes or static classes with consts :)

  • Django paging object has issues with Postgresql QuerySets

    - by pivotal
    I have some django code that runs fine on a SQLite database or on a MySQL database, but it runs into problems with Postgres, and it's making me crazy that no one has has this issue before. I think it may also be related to the way querysets are evaluated by the pager. In a view I have: def index(request, page=1): latest_posts = Post.objects.all().order_by('-pub_date') paginator = Paginator(latest_posts, 5) try: posts = paginator.page(page) except (EmptyPage, InvalidPage): posts = paginator.page(paginator.num_pages) return render_to_response('blog/index.html', {'posts' : posts}) And inside the template: {% for post in posts.object_list %} {# some rendering jazz #} {% endfor %} This works fine with SQLite, but Postgres gives me: Caught TypeError while rendering: 'NoneType' object is not callable To further complicate things, when I switch the Queryset call to: latest_posts = Post.objects.all() Everything works great. I've tried re-reading the documentation, but found nothing, although I admit I'm a bit clouded by frustration at this point. What am I missing? Thanks in advance.

  • How can I quickly set up a RESTful site using PHP without a Framework?

    - by Sanoj
    I would like to quickly set up a RESTful site using PHP without learning a PHP Framework. I would like to use a single .htaccess-file in Apache (no mod_rewrite) or a single rule using Nginx, so I easyli can change web server without changing my code. So I want to direct all requests to a single PHP-file, and that file takes care of the RESTful-handling and call the right PHP-file. In example: The user request http://mysite.com/test The server sends all requests to rest.php The rest.php call test.php (maybe with a querystring). If this can be done, is there a free PHP-script that works like my rest.php? or how can I do this PHP-script?

  • Form character encoding problems with special characters

    - by Enrique
    Hello I have a jsp with an html form. I set the content type like this: <%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1" %> When I send special characters like á é í ó ú they are saved correctly in the database. My table charset is utf-8. I want to change iso-8859 to utf-8 like this to standardize my application and accept more special characters: <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8" %> but when I change it to utf-8 the special characters á é í ó ú are not saved correctly in the databse. When I try to save á it is saved as á In the server side I'm using Spring MVC. I'm getting the text field value like this: String strField = ServletRequestUtils.getStringParameter(request, "field");

  • How to enable reading non-ascii characters in Servlets

    - by Daziplqa
    How to make the servlet accept non-ascii (Arabian, chines, etc) characters passed from JSPs? I've tried to add the following to top of JSPs: <%@page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> And to add the following in each post/get method in the servlet: request.setCharacterEncoding("UTF-8"); response.setCharacterEncoding("UTF-8"); I've tried to add a Filter that executes the above two statements instead of in the servlet. To be quite honest, these was working in the past, but now it doesn't work anymore. I am using tomcat 5.0.28/6.x.x on JDK1.6 on both Win & Linux boxes.

  • Keeping connection to APNs open on App Engine using Modules in Go

    - by user3727820
    I'm trying to implement iOS push notifications for a messageboard app I've written (so like notification for new message ect. ect.) but have no real idea where to start. Alot the current documentation seems to be out of date in regard to keeping persistent TLS connections open to the APNs from App Engine and links to articles about depreciated backends I'm using the Go runtime and just keep getting stuck. For instance, the creation of the socket connection to APNs requires a Context which can only be got from a HTTP request, but architecturally this doesn't seem to make a lot of sense because ideally the socket remains open regardless. Is there any clearer guides around that I'm missing or right now is it a better idea to setup a separate VPS or compute instance to handle it?

  • Multiple ASP.Net Controls On One Page

    - by Duracell
    We have created a User Control for ASP.Net. At any one time, a user's profile page could contain between one and infinity of these controls. The Control.ascx file contains quite a bit of javascript. When the control is rendered by .Net to HTML, you notice that it prints the javascript for each control. This was expected. I'd like to reduce the amount of HTML output by the server to increase page load times. Normally, you could just move the javascript to an external file and then you only need one extra HTTP request which will serve for all controls. But what about instances in the javascript where we have something like document.getElementById('<%= txtTextBox.ClientID %'); How would the javascript know which user control work with? Has anyone done something like this, or is the solution staring me in the face?

  • URL of the website calling Restlet API

    - by Christopher McCann
    I have a Restlet API and the methods exposed on it are called by a PHP web app. This web app is accessible by several domain names and depending on the domain certain aspects of the app are changed (look and feel, content etc). Is there a way for Restlet to determine the URL of the calling web app? I have used getReference() but all I can get is the (internal) IP address of the calling web server (not the domain name). My only other alternative is to pass the URL of the web app with every request to the API but it would be cleaner if Restlet already knew. Thanks

  • How to store the result of a JSP in a string?

    - by Spines
    I want to store the result of a JSP in a string. For example, I want to be able to call a function like: String result = ProcessJsp("/jspfile.jsp"); Also, this must be rather efficient. Making a url request to the jsp and then storing it would definitely be too slow. How could I do this? Here are my thoughts on how to do this, though I'm not sure if it would work, and I'm hoping there is something simpler: Do RequestDispatcher("/jspfile.jsp").include(hreq, hresp), but instead of putting the real HttpResponse object in there, you put your own where the getWriter() method returns something that writes to your String or a memory buffer, etc.

  • Github svn interface

    - by Fabio
    I recently moved a project on github and I still use this library in some svn projects as external. However I can't get github svn interface working at this time. If I run svn list http://svn.github.com/fabn/zle.git I obtain this error svn: Server sent unexpected return value (500 Internal Server Error) in response to PROPFIND request for '/fabn/zle.git/!svn/bc/0' If I run the same command using a fork of my project the list (and also the checkout) goes fine and i obtain what I need (this is the command svn list http://svn.github.com/JellyBelly/zle.git) Is there anything I can do to resolve this issue or it's a github problem?

Is anyone knows what can cause this problem? the new checksum in other packets is calculated as it should be.. but in the HTTP packet it doesn't..

  • how do i use a .dat file as a model for an entity in minecraft?

    - by user1835502
    the entity does not have to do anything, just stand there like a statue, or it doesn't have to be an entity at all, just so the .dat file renders in minecraft i saw this http://pastebin.com/jP4diLJ9 in a java file that came with a .exe, and in the .exe you can choose one of the .dat files and it will show you it as a model, i also asked on minecraft forums and someone said it was possible but i have no idea how maybe has something to do with this try { FileOutputStream fileoutputstream = new FileOutputStream("./Models/"+id+".dat"); fileoutputstream.write(b, 0, b.length); fileoutputstream.close(); } catch(Throwable _ex) {} or if(i 0) {//grabs all models System.out.println("Sending request for Model: "+i); addRequest( 7, i); byte b[] = pack.unpack(download().buffer); if(pack.unpacked) { savemodel(i,b); System.out.println("Model Saved"); }else{ System.out.println("Model Grabbing Complete"); break;

    Hello All, I am developing a web application using Struts 1.2.7 I want to print a list of integers using the tag.

The code sample is as follows: <logic:iterate name="intList" id="integer" > <bean:write name="integer" /> <logic:iterate /> Here intList is a List of int(s) passed as a request attribute to the jsp page under consideration.

  • Kohana v3, escape illegal characters?

    - by Dom
    Quick question, does Kohana (version 3) automatically escape data that is passed into ORM::factory..... (and everywhere else that has to do with the database)? For example: $thread = ORM::factory('thread', $this->request->param('id')); Would the data passed in the second argument be auto-escaped before it goes in the SQL query or do I have to manually do it? Probably a stupid question and it's better to be safe than sorry, but yeah... I usually do manually escape the data, but I want to know if Kohana does this for me? Thanks

  • Using java class HttpsURLConnection

    - by KB22
    Hi all, I have a small piece of code which basically impements a HTTP-Client, i.e. it POSTS request and works with re RESPONSE. As long as HTTP is concenerned everthing work well. For some reason I now have to support HTTPS too. So here is briefly what I do in order to get a connection opened: URL url = new URL(serverAddress); HttpsURLConnection httpsConn = (HttpsURLConnection) url.openConnection(); This fails, stating: sun.net.www.protocol.https.HttpsURLConnectionImpl cannot be cast to com.sun.net.ssl.HttpsURLConnection I guess this is kinda trivial, but I just don't get what I'm doing wrong in this one... Googled it, and the code just looks right - not? any ideas are appreciated! thanks, K

  • Is there a better way to serially submit multiple AJAX requests?

    - by friedo
    I have a page with multiple forms that I submit via Ajax POSTs serially. At first, I tried using synchronous XHR requests, but this causes the browser to lock up for the duration of the request, and breaks my DOM-manipulation effects, which is unacceptable. So the pattern I ended up using is basically this: var fcount = 0; // incremented for each form to be submitted function submit_form( num ) { var fdata = { ... }; // data from form # num $.ajax( { async: true, url: '/index.cgi', data: fdata, type: 'POST', success: function() { if ( num < fcount ) { submit_form( ++num ); } } } ); } $( '#submit_form_btn' ).click( function() { submit_form( 1 ) } ); The recursion strikes me as a bit of an ugly solution to what is essentially an iterative problem. Is there a cleaner or more elegant way that this could be handled?

  • Replacing delimiter characters in file path

    - by salvationishere
    I'm developing a C# web application in VS 2008. I let the user select an input file and then I store the file path in a string variable. However, it stores this path as "C:\\folder\\...". So my question is how do I convert this file path into single "\"? To clarify more, this is my code in context. Currently it is entering the If Directory does not Exist section. protected void btnAppend_Click(object sender, EventArgs e) { string fullpath = Page.Request.PhysicalPath; fullpath.Replace('\\', '\'); if (!Directory.Exists(fullpath)) { string msg = "<h1>The upload path doesn't exist: {0}</h1>";

  • What's a good way to detect wrap-around in a fixed-width message counter?

    - by Kristo
    I'm writing a client application to communicate with a server program via UDP. The client periodically makes requests for data and needs to use the most recent server response. The request message has a 16-bit unsigned counter field that is echoed by the server so I can pair requests with server responses. Since it's UDP, I have to handle the case where server responses arrive out of order (or don't arrive at all). Naively, that means holding on to the highest message counter seen so far and dropping any incoming message with a lower number. But that will fail as soon as we pass 65535 messages and the counter wraps back to zero. Is there a good way to detect (with reasonable probability) that, for example, message 5 actually comes after message 65,000? The implementation language is C++.

  • DNS Lookup in simple C#/asp.net ajax call is extremely slow

    - by Ryan
    I'm running this out of the VS 2008 debugger on Windows 7, running .Net 3.5. The idea was to make all ajax requests with jQuery only, rather than .net, following some tutorials online. Default.aspx - HTML page, jquery triggers method in Default.aspx.cs http://pastebin.com/pxBvKA2H Default.aspx.cs - C# Webform, just defines a GetDate fuction, which only returns a string for now (trying to eliminate any possible issues) (can only post one hyperlink...) pastebin.com/pnHn50hu The ajax query takes longer than it should. Profiling with firebug revealed that it took 1.03 ms. 1s DNS Lookup | 26ms Waiting | 1ms Receiving EDIT: It continues to take the same set of times if you continue to click and resubmit the request. Is there anything I can do to cut down on the DNS Lookup time / what did I do wrong? Thanks for any help.

  • Display/Hide part of a list

    - by superexsl
    Hi I have an (unordered)list (generated by a repeater) of items. However, I'd like to show the first three items, and have the rest hidden by the main content div. When a button is pressed, I would like the list's div to expand, pushing the main content div down and showing the rest of the list. I was thinking of using slideDown(), but that closes the entire div ( and I would like to show the first 3 items of the list). What would be the best way to achieve an effect like this? Is there a plugin that can easily show X items of a list and the display the rest upon request? Thanks
