    android webview client-server android-webview server-side
    To be succinct, I want to know how android webview works underneath the covers. I’ve scoured the Internet and cannot find an article or resource which discusses the innerworkings of the webview class. It essentially is an emulator for viewing web pages in the browser, right? Does that mean it employs a strict client-server relationship, a la the Android browser, or is it more complicated than that?Is there any reason a web page will display perfectly in the Android browser, yet produce server

    java ruby-on-rails server-side
    After building 5 Rails websites and having to Deal with Rails 2.3, 3.0 and 3.1 version differences, installation hassles and unexpected memory spikes with Ruby and other gotchas, I’ve decided to make the move to Java Backend Web Development using Spring. I’m aware that there is a world of difference between the two and JSP development isn’t a next step after Rails development, but my major points are that:a) Java is a much more mature, faster and efficient programming language compared to Ruby.

    node.js server-side bots
    I made a bot (https://github.com/JBader89/PlugBot) for a social music site, and I’d like to have it running 24/7. I used node.js to create and run it, so I was wondering if there’s a way to use node.js to make it run continually?

    I am working on a registration page for my website, but I keep getting a syntax error no matter what I do. If I remove the entire statement, it leaves me alone but I can’t then do what I want. Here is the code:<?php $user=$pass=$mail=$name=””; $registered=true; $user = $_GET[“user”]; $file = fopen(“sparkapps_files/users.dat”,”r+”) or fopen (“sparkapps_files/users.dat”,”x+”); if (strlen($user)< “4”) {echo “Username too short!

    ruby server-side erb middleman embedded-ruby
    I have a static site generated using the excellent Middleman. It has been running happily on an Apache server. I now need to add some embedded Ruby to one of the pages (Ruby that must be evaluated at runtime, not during Middleman’s build phase). I won’t go into what form this code takes, but for this question please assume that it has to be embedded Ruby.So what are my options?

    gwt properties server-side
    I have a file variables.properties in my GWT application inside the war folder. The file contains a jdbc string, username and password, hence I would not like to see it on the client side in any way.My question: Is variables.properties somehow integrated into client side code at runtime when placed inside the war folder or is it safe to place it there?If it is not, where should I put it? I read the file with this code:variables = new Properties(); BufferedInputStream stream = new BufferedInputSt

    asp.net apache windows-server-2003 server-side
    I’ve heard of ASP.NET compiled DLLs which only works on Windows Server, but I would like to know if there are any other compiled server side languages?, maybe even ones for Apache server?Installation of the runtime shouldn’t be a problem because I will have physical access to the Unix/Windows servers, but if it is a CGI plugin its an added benefit since I can install it using only FTP.

    I have a drop down list and it has values through 2 to 12. and two text boxes are being displayed. What I want is when user change the dropdown’s value, text boxes should be generated according to the count. Should I do this on server side? I think it would be more better if done on client side. Please help me with code samples. Thank you in advance.

    server-side sniffing
    Netcraft is able to get statistics for millions of sites what web technology (PHP, ASP.NET, Java Servlet etc.) they are using on their servers. I was wondering how they do that from the outside and whether there is some script that can be used to check the server side technology for a random site?

    ajax server-side business-logic
    A typical stack for a web application is a database, a server with server-side code, and a user with a browser with HTML/CSS/JavaScript.Before extensive AJAX, MVC in which the controller was the server-side code rulled. A server had to route answer requests for Dynamic web pages (i.e. templated html solutions like JSP and ASP). The server to coordinate the calls to the database and decide which dynamic page to use to answer the page request. The result of all of this is that server ended up c

    architecture applications cross-platform server-side
    We consider a server app development – heavily loaded with messing with big data streams. An app will be running on one powerful server. A server app will be developed in form of crossplatform application – working on Windows, Mac OS X and Linux. So same code, many platforms for stand alone server architecture. We wonder what are the benefits of distributing applications not only over threads but over processes as well, for programmers and server end users?Some people said to me that even having

It will require 4 pieces (Marionette/Backbone only, you will still need the web service replying to sessions requests) to effectively work. I created a Gists for anyone to look at. Feel free to update the gists and I’ll pull the code, granted that it’s free of bugs.I use jQuery, require.js, text require.js plugin, handlebars and moment.js. main.js includes all hooks for using handlebars to load the template from dis

Right now, no results are being shown (I get the “No records found.” message). Can’t seem to find an answer on the web. The call to alert() shows the correct numbers, so I know something is being returned from the server. I suspect the issue is in jobsCallback or handleDataReturnPayload but am stuck from there. Any
