  • Is there an alternative Skype client?

    - by Joseph
    I love Ubuntu, but one thing I think is a pain is skype for it. It's outdated, buggy and generally just not as smooth as a lot of the other Ubuntu software. Is there an alternative for it? I'm not speaking about another IM like AIM or Live Messenger. Put another piece of software like the native app that comes with Ubuntu, that allows me to sign into Skype as well? Or is there perhaps a plugin for the native Ubuntu chat app that allows Skype contacts, calling etc. etc.

  • Error opening .wmv file

    - by Dcm1405
    I tried to open a .wmv file in Thunderbird. I was asked to download files in order to have it accessible. At the end of the installation An error occurred - Location not found. error message displayed with just the OK button available. Now when I press the Play button just the error message displays so I am not sure which packages need to be installed/uninstalled. I have installed Ubuntu 12.04 (32-bit) with open-jdk-7. Error was generated when installing: GStreamer ffmpeg video plugin It seemed that it took a while to have the process completing all steps of the download / install before the error message displayed.

  • Methods to Validate User Supplied Data

    - by clifgray
    I am working on a website where users record data from certain locations and they input an address to tag that location with a GPS coordinate. Pretty frequently those locations are tagged more than a mile away from the actual location and I am trying to implement a few ways to validate the data. Right now I am thinkiing of: having a tag of location pages for other users to say "incorrect location" so I can go one by one and fix it letting users with a decent amount of experience (reputation) edit the location GPS coordinates making the location be validated by a mod before it goes live and they make sure it is a good location Are these reasonable? I know the first will take a lot of my time and I would love some suggestions.

  • how to reinstall ubuntu 12.04 after dual boot installation fails with windows 7

    - by Rini
    I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio s series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/ Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD. Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error. There is only one partition which corresponds to windows 7 but I don't know whether the Ubuntu is still there or probably corrupted. So, how to repair it or again install ubuntu ? Please suggest what I should do now? Thanks in advance. R Shukla

  • The JavaOne 2012 Sunday Technical Keynote

    - by Janice J. Heiss
    At the JavaOne 2012 Sunday Technical Keynote, held at the Masonic Auditorium, Mark Reinhold, Chief Architect, Java Platform Group, stated that they were going to do things a bit differently--"rather than 20 minutes of SE, and 20 minutes of FX, and 20 minutes of EE, we're going to mix it up a little," he said. "For much of it, we're going to be showing a single application, to show off some of the great work that's been done in the last year, and how Java can scale well--from the cloud all the way down to some very small embedded devices, and how JavaFX scales right along with it."Richard Bair and Jasper Potts from the JavaFX team demonstrated a JavaOne schedule builder application with impressive navigation, animation, pop-overs, and transitions. They noted that the application runs seamlessly on either Windows or Macs, running Java 7. They then ran the same application on an Ubuntu Linux machine--"it just works," said Blair.The JavaFX duo next put the recently released JavaFX Scene Builder through its paces -- dragging and dropping various image assets to build the application's UI, then fine tuning a CSS file for the finished look and feel. Among many other new features, in the past six months, JavaFX has released support for H.264 and HTTP live streaming, "so you can get all the real media playing inside your JavaFX application," said Bair. And in their developer preview builds of JavaFX 8, they've now split the rendering thread from the UI thread, to better take advantage of multi-core architectures.Next, Brian Goetz, Java Language Architect, explored language and library features planned for Java SE 8, including Lambda expressions and better parallel libraries. These feature changes both simplify code and free-up libraries to more effectively use parallelism. "It's currently still a lot of work to convert an application from serial to parallel," noted Goetz.Reinhold had previously boasted of Java scaling down to "small embedded devices," so Blair and Potts next ran their schedule builder application on a small embedded PandaBoard system with an OMAP4 chip set. Connected to a touch screen, the embedded board ran the same JavaFX application previously seen on the desktop systems, but now running on Java SE Embedded. (The systems can be seen and tried at four of the nearby JavaOne hotels.) Bob Vandette, Java Embedded Architect, then displayed a $25 Rasberry Pi ARM-based system running Java SE Embedded, noting the even greater need for the platform independence of Java in such highly varied embedded processor spaces. Reinhold and Vandetta discussed Project Jigsaw, the planned modularization of the Java SE platform, and its deferral from the Java 8 release to Java 9. Reinhold demonstrated the promise of Jigsaw by running a modularized demo version of the earlier schedule builder application on the resource constrained Rasberry Pi system--although the demo gods were not smiling down, and the application ultimately crashed.Reinhold urged developers to become involved in the Java 8 development process--getting the weekly builds, trying out their current code, and trying out the new features:http://openjdk.java.net/projects/jdk8http://openjdk.java.net/projects/jdk8/spechttp://jdk8.java.netFrom there, Arun Gupta explored Java EE. The primary themes of Java EE 7, Gupta stated, will be greater productivity, and HTML 5 functionality (WebSocket, JSON, and HTML 5 forms). Part of the planned productivity increase of the release will come from a reduction in writing boilerplate code--through the widespread use of dependency injection in the platform, along with default data sources and default connection factories. Gupta noted the inclusion of JAX-RS in the web profile, the changes and improvements found in JMS 2.0, as well as enhancements to Java EE 7 in terms of JPA 2.1 and EJB 3.2. GlassFish 4 is the reference implementation of Java EE 7, and currently includes WebSocket, JSON, JAX-RS 2.0, JMS 2.0, and more. The final release is targeted for Q2, 2013. Looking forward to Java EE 8, Gupta explored how the platform will provide multi-tenancy for applications, modularity based on Jigsaw, and cloud architecture. Meanwhile, Project Avatar is the group's incubator project for designing an end-to-end framework for building HTML 5 applications. Santiago Pericas-Geertsen joined Gupta to demonstrate their "Angry Bids" auction/live-bid/chat application using many of the enhancements of Java EE 7, along with an Avatar HTML 5 infrastructure, and running on the GlassFish reference implementation.Finally, Gupta covered Project Easel, an advanced tooling capability in NetBeans for HTML5. John Ceccarelli, NetBeans Engineering Director, joined Gupta to demonstrate creating an HTML 5 project from within NetBeans--formatting the project for both desktop and smartphone implementations. Ceccarelli noted that NetBeans 7.3 beta will be released later this week, and will include support for creating such HTML 5 project types. Gupta directed conference attendees to: http://glassfish.org/javaone2012 for everything about Java EE and GlassFish at JavaOne 2012.

  • Moving from local machine to group web development environment

    - by Djave
    I'm a freelancer who currently creates websites locally using something like MAMP to test websites locally before pushing them live with FTP. I'm looking at taking on my first employee, and I would need to be able to work on websites with them simultaneously. Can anyone explain or provide links to some good documentation on team workflow, or some key phrases I should be googling to get started on my set up? Unlike a lot of the stackoverflow community I've never worked in a dev team, large or small as I'm self taught so just need to know where to start. At present I'm thinking I need an extra computer to use as a server, then use Git or some such to version control files on that computer, as well as installing apache on it so it can be viewed by any computers in my current home network. Is this heading down the right track?

  • Is it safe to resize root partition?

    - by binW
    My HDD is partitioned into two equal sized partitions. First is being used for Windows and Second for Ubuntu. Everything is working fine. But now I want to remove Windows and use the disk completely for Ubuntu. I can easily boot from live cd and use GParted to delete Windows partition and then expand Ubuntu partition to use the whole hard disk. But I want to know if its safe i.e Will resizing Ubuntu partition change any thing else like the partition UUID or any thing else? Do I need to reinstall grub after resizing the root partition? It would be great if some one who has already done this can give their advice here.

  • Pls help Installation has ruined laptop

    - by user287694
    Hi this was my time using Linux. So I installed Ubuntu from Windows 7 via USB. After booting into Ubuntu I proceeded to do a full install over windows. This seemed to be going fine but at the point where I was to sign up to Ubuntu one it froze. After awhile maybe 30 mins I realised nothing was going to happen, so I restarted. Now after the bios options bit passes all I get is a prompt flashing at the top left of a black screen. I have tried booting up via USB option but nothing happens, I have tried this 6 or 7 times with fresh usb each time and also with lubuntu. I'm not sure if I have correctly made a live usb obviously I believe I have been but being new I can't guarantee this. Can anyone help me get some functional out of my laptop. Thanks Ben

  • Three Hidden Extensibility Gems in ASP.NET 4

    ASP.NET 4 introduces a few new extensibility APIs that live the hermit lifestyle away from the public eye. Theyre not exactly hidden - they are well documented on MSDN - but they arent well publicized. Its about time we shine a spotlight on them. PreApplicationStartMethodAttribute This new attribute allows you to have code run way early in the ASP.NET pipeline as an application starts up. I mean way early, even before Application_Start. This happens to also be before code in your App_code folder...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

    Provisioning my Oracle database instance to AWS EC2 RDB was easy. Just a few clicks! However, getting my connection to my Oracle cloud database was not as easy. A couple things that are not obvious (using Oracle SQL Developer): 1. Need to set up a database security group. 2. Need to use end point for the host name.

  • SEO optimisation problems after Google Panda [on hold]

    - by Daniel West
    I am currently trying to improve a website's SEO after it took quite a hit from the Google Panda upgrades. What are the main things I need to look at improving when trying to improve its ranking in Google? I have already made sure that the pages validate to W3C Standards, minimized css and js and done the obvious meta tags and header optimization but this hasn't made any difference yet. It could possibly be a content issue as the pages currently read much like a brochure and there were some pages with just a video and no text content on them which is also an issue. I've added a rel="nofollow" attribute to the links to these pages although i'm told this doesn't really work anymore. If anyone has any ideas let me know. Cheers!

  • Creating a remote management interface

    - by Johnny Mopp
    I'm looking for info on creating a remote management interface for our software. This is not anything illicit. Our software is for live TV production and once they go on-air we can't access the PC (usually through LogMeIn). I would like to be able to upload/download files and issue commands to our software. The commands would be software specific like "load this file" or "run this script" or "return this value" etc. A socket connection is preferred but the problem is most of our PCs are behind firewalls and NAT servers. I'm not sure where to start. I think HTTP tunneling is the way to go but am wondering if there are other options or recommendations. Also, assume our clients are not willing to open up ports for security reasons. Thanks.

  • Using the jQuery UI Library in a MVC 3 Application to Build a Dialog Form

    - by ChrisD
    Using a simulated dialog window is a nice way to handle inline data editing. The jQuery UI has a UI widget for a dialog window that makes it easy to get up and running with it in your application. With the release of ASP.NET MVC 3, Microsoft included the jQuery UI scripts and files in the MVC 3 project templates for Visual Studio. With the release of the MVC 3 Tools Update, Microsoft implemented the inclusion of those with NuGet as packages. That means we can get up and running using the latest version of the jQuery UI with minimal effort. To the code! Another that might interested you about JQuery Mobile and ASP.NET MVC 3 with C#. If you are starting with a new MVC 3 application and have the Tools Update then you are a NuGet update and a <link> and <script> tag away from adding the jQuery UI to your project. If you are using an existing MVC project you can still get the jQuery UI library added to your project via NuGet and then add the link and script tags. Assuming that you have pulled down the latest version (at the time of this publish it was 1.8.13) you can add the following link and script tags to your <head> tag: < link href = "@Url.Content(" ~ / Content / themes / base / jquery . ui . all . css ")" rel = "Stylesheet" type = "text/css" /> < script src = "@Url.Content(" ~ / Scripts / jquery-ui-1 . 8 . 13 . min . js ")" type = "text/javascript" ></ script > The jQuery UI library relies upon the CSS scripts and some image files to handle rendering of its widgets (you can choose a different theme or role your own if you like). Adding these to the stock _Layout.cshtml file results in the following markup: <!DOCTYPE html> < html > < head >     < meta charset = "utf-8" />     < title > @ViewBag.Title </ title >     < link href = "@Url.Content(" ~ / Content / Site . css ")" rel = "stylesheet" type = "text/css" />     <link href="@Url.Content("~/Content/themes/base/jquery.ui.all.css")" rel="Stylesheet" type="text/css" />     <script src="@Url.Content("~/Scripts/jquery-1.5.1.min.js")" type="text/javascript"></script>     <script src="@Url.Content("~/Scripts/modernizr-1.7.min . js ")" type = "text/javascript" ></ script >     < script src = "@Url.Content(" ~ / Scripts / jquery-ui-1 . 8 . 13 . min . js ")" type = "text/javascript" ></ script > </ head > < body >     @RenderBody() </ body > </ html > Our example will involve building a list of notes with an id, title and description. Each note can be edited and new notes can be added. The user will never have to leave the single page of notes to manage the note data. The add and edit forms will be delivered in a jQuery UI dialog widget and the note list content will get reloaded via an AJAX call after each change to the list. To begin, we need to craft a model and a data management class. We will do this so we can simulate data storage and get a feel for the workflow of the user experience. The first class named Note will have properties to represent our data model. namespace Website . Models {     public class Note     {         public int Id { get ; set ; }         public string Title { get ; set ; }         public string Body { get ; set ; }     } } The second class named NoteManager will be used to set up our simulated data storage and provide methods for querying and updating the data. We will take a look at the class content as a whole and then walk through each method after. using System . Collections . ObjectModel ; using System . Linq ; using System . Web ; namespace Website . Models {     public class NoteManager     {         public Collection < Note > Notes         {             get             {                 if ( HttpRuntime . Cache [ "Notes" ] == null )                     this . loadInitialData ();                 return ( Collection < Note >) HttpRuntime . Cache [ "Notes" ];             }         }         private void loadInitialData ()         {             var notes = new Collection < Note >();             notes .

Cache [ "Notes" ] = notes ;         }         public Collection < Note > GetAll ()         {             return Notes ;         }         public Note GetById ( int id )         {             return Notes . Where ( i => i . Id == id ). FirstOrDefault ();         }         public int Save ( Note item )         {             if ( item . Id <= 0 )                 return saveAsNew ( item );             var existingNote = Notes . Where ( i => i . Id == item . Id ). FirstOrDefault ();             existingNote . Title = item . Title ;             existingNote . Body = item . Body ;             return existingNote . Id ;         }         private int saveAsNew ( Note item )         {             item . Id = Notes . Count + 1 ;             Notes . Add ( item );             return item . Id ;         }     } } The class has a property named Notes that is read only and handles instantiating a collection of Note objects in the runtime cache if it doesn't exist, and then returns the collection from the cache. This property is there to give us a simulated storage so that we didn't have to add a full blown database (beyond the scope of this post). The private method loadInitialData handles pre-filling the collection of Note objects with some initial data and stuffs them into the cache. Both of these chunks of code would be refactored out with a move to a real means of data storage. The GetAll and GetById methods access our simulated data storage to return all of our notes or a specific note by id. The Save method takes in a Note object, checks to see if it has an Id less than or equal to zero (we assume that an Id that is not greater than zero represents a note that is new) and if so, calls the private method saveAsNew . If the Note item sent in has an Id , the code finds that Note in the simulated storage, updates the Title and Description , and returns the Id value. The saveAsNew method sets the Id , adds it to the simulated storage, and returns the Id value. The increment of the Id is simulated here by getting the current count of the note collection and adding 1 to it. The setting of the Id is the only other chunk of code that would be refactored out when moving to a different data storage approach. With our model and data manager code in place we can turn our attention to the controller and views. We can do all of our work in a single controller. If we use a HomeController , we can add an action method named Index that will return our main view. An action method named List will get all of our Note objects from our manager and return a partial view. We will use some jQuery to make an AJAX call to that action method and update our main view with the partial view content returned. Since the jQuery AJAX call will cache the call to the content in Internet Explorer by default (a setting in jQuery), we will decorate the List, Create and Edit action methods with the OutputCache attribute and a duration of 0. This will send the no-cache flag back in the header of the content to the browser and jQuery will pick that up and not cache the AJAX call. The Create action method instantiates a new Note model object and returns a partial view, specifying the NoteForm.cshtml view file and passing in the model. The NoteForm view is used for the add and edit functionality. The Edit action method takes in the Id of the note to be edited, loads the Note model object based on that Id , and does the same return of the partial view as the Create method. The Save method takes in the posted Note object and sends it to the manager to save. It is decorated with the HttpPost attribute to ensure that it will only be available via a POST. It returns a Json object with a property named Success that can be used by the UX to verify everything went well (we won't use that in our example). Both the add and edit actions in the UX will post to the Save action method, allowing us to reduce the amount of unique jQuery we need to write in our view. The contents of the HomeController.cs file: using System . Web . Mvc ; using Website . Models ; namespace Website . Controllers {     public class HomeController : Controller     {         public ActionResult Index ()         {             return View ();         }         [ OutputCache ( Duration = 0 )]         public ActionResult List ()         {             var manager = new NoteManager ();             var model = manager . GetAll ();             return PartialView ( model );         }         [ OutputCache ( Duration = 0 )]         public ActionResult Create ()         {             var model = new Note ();             return PartialView ( "NoteForm" , model );         }         [ OutputCache ( Duration = 0 )]         public ActionResult Edit ( int id )         {             var manager = new NoteManager ();             var model = manager . GetById ( id );             return PartialView ( "NoteForm" , model );         }         [ HttpPost ]         public JsonResult Save ( Note note )         {             var manager = new NoteManager ();             var noteId = manager . Save ( note );             return Json ( new { Success = noteId > 0 });         }     } } The view for the note form, NoteForm.cshtml , looks like so: @model Website . Models . Note @using ( Html . BeginForm ( "Save" , "Home" , FormMethod . Post , new { id = "NoteForm" })) { @Html . Hidden ( "Id" ) < label class = "Title" >     < span > Title < /span><br / >     @Html . TextBox ( "Title" ) < /label> <label class="Body">     <span>Body</ span >< br />     @Html . TextArea ( "Body" ) < /label> } It is a strongly typed view for our Note model class. We give the <form> element an id attribute so that we can reference it via jQuery. The <label> and <span> tags give our UX some structure that we can style with some CSS. The List.cshtml view is used to render out a <ul> element with all of our notes. @model IEnumerable < Website . Models . Note > < ul class = "NotesList" >     @foreach ( var note in Model )     {     < li >         @note . Title < br />         @note . Body < br />         < span class = "EditLink ButtonLink" noteid = "@note.Id" > Edit < /span>     </ li >     } < /ul> This view is strongly typed as well. It includes a <span> tag that we will use as an edit button. We add a custom attribute named noteid to the <span> tag that we can use in our jQuery to identify the Id of the note object we want to edit. The view, Index.cshtml , contains a bit of html block structure and all of our jQuery logic code. @ {     ViewBag . Title = "Index" ; } < h2 > Notes < /h2> <div id="NoteListBlock"></ div > < span class = "AddLink ButtonLink" > Add New Note < /span> <div id="NoteDialog" title="" class="Hidden"></ div > < script type = "text/javascript" >     $ ( function () {         $ ( "#NoteDialog" ). dialog ({             autoOpen : false , width : 400 , height : 330 , modal : true ,             buttons : {                 "Save" : function () {                     $ . post ( "/Home/Save" ,                         $ ( "#NoteForm" ). serialize (),                         function () {                             $ ( "#NoteDialog" ). dialog ( "close" );                             LoadList ();                         });                 },                 Cancel : function () { $ ( this ). dialog ( "close" ); }             }         });         $ ( ".EditLink" ). live ( "click" , function () {             var id = $ ( this ). attr ( "noteid" );             $ ( "#NoteDialog" ). html ( "" )                 . dialog ( "option" , "title" , "Edit Note" )                 . load ( "/Home/Edit/" + id , function () { $ ( "#NoteDialog" ). dialog ( "open" ); });         });         $ ( ".AddLink" ). click ( function () {             $ ( "#NoteDialog" ). html ( "" )                 . dialog ( "option" , "title" , "Add Note" )                 . load ( "/Home/Create" , function () { $ ( "#NoteDialog" ). dialog ( "open" ); });         });         LoadList ();     });     function LoadList () {         $ ( "#NoteListBlock" ). load ( "/Home/List" );     } < /script> The <div> tag with the id attribute of "NoteListBlock" is used as a container target for the load of the partial view content of our List action method. It starts out empty and will get loaded with content via jQuery once the DOM is loaded. The <div> tag with the id attribute of "NoteDialog" is the element for our dialog widget. The jQuery UI library will use the title attribute for the text in the dialog widget top header bar. We start out with it empty here and will dynamically change the text via jQuery based on the request to either add or edit a note. This <div> tag is given a CSS class named "Hidden" that will set the display:none style on the element. Since our call to the jQuery UI method to make the element a dialog widget will occur in the jQuery document ready code block, the end user will see the <div> element rendered in their browser as the page renders and then it will hide after that jQuery call. Adding the display:hidden to the <div> element via CSS will ensure that it is never rendered until the user triggers the request to open the dialog. The jQuery document load block contains the setup for the dialog node, click event bindings for the edit and add links, and a call to a JavaScript function called LoadList that handles the AJAX call to the List action method. The .dialog() method is called on the "NoteDialog" <div> element and the options are set for the dialog widget. The buttons option defines 2 buttons and their click actions. The first is the "Save" button (the text in quotations is used as the text for the button) that will do an AJAX post to our Save action method and send the serialized form data from the note form (targeted with the id attribute "NoteForm"). Upon completion it will close the dialog widget and call the LoadList to update the UX without a redirect. The "Cancel" button simply closes the dialog widget. The .live() method handles binding a function to the "click" event on all elements with the CSS class named EditLink . We use the .live() method because it will catch and bind our function to elements even as the DOM changes. Since we will be constantly changing the note list as we add and edit we want to ensure that the edit links get wired up with click events. The function for the click event on the edit links gets the noteid attribute and stores it in a local variable. Then it clears out the HTML in the dialog element (to ensure a fresh start), calls the .dialog() method and sets the "title" option (this sets the title attribute value), and then calls the .load() AJAX method to hit our Edit action method and inject the returned content into the "NoteDialog" <div> element. Once the .load() method is complete it opens the dialog widget. The click event binding for the add link is similar to the edit, only we don't need to get the id value and we load the Create action method. This binding is done via the .click() method because it will only be bound on the initial load of the page. The add button will always exist. Finally, we toss in some CSS in the Content/Site.css file to style our form and the add/edit links. . ButtonLink { color : Blue ; cursor : pointer ; } . ButtonLink : hover { text - decoration : underline ; } . Hidden { display : none ; } #NoteForm label { display:block; margin-bottom:6px; } #NoteForm label > span { font-weight:bold; } #NoteForm input[type=text] { width:350px; } #NoteForm textarea { width:350px; height:80px; } With all of our code in place we can do an F5 and see our list of notes: If we click on an edit link we will get the dialog widget with the correct note data loaded: And if we click on the add new note link we will get the dialog widget with the empty form: The end result of our solution tree for our sample:

  • Support for 15,000 Partitions in SQL Server 2008 SP2 and SQL Server 2008 R2 SP1

    In SQL Server 2008 and SQL Server 2008 R2, the number of partitions on tables and indexes is limited to 1,000. This paper discusses how SQL Server 2008 SP2 and SQL Server 2008 R2 SP1 address this limitation by providing an option to increase the limit to 15,000 partitions. It describes how support for 15,000 partitions can be enabled and disabled on a database. It also talks about performance characteristics, certain limitations associated with this support, known issues, and their workarounds. This support is targeted to enterprise customers and ISVs with large-scale decision support or data warehouse requirements.

  • Packard Bell Easynote NJ65 not saving gamma Setup.

    - by Pablo Gomez
    Hi. There seems to be a issue with the Easynote range of PB laptops. Since Ubuntu 10.10 does not use a Xorg.conf file to save your gamma / resolution /brightness setting, everytime I turn on my laptop I have to open up a terminal window and use the x-gamma command to set it up to my personal preference. Is there a way to create a configuration file which can save that into the system everytime I load up the OS? When I used to have a Compaq Presario (an F564LA with integrated nVIDIA graphics), I could save a config. file into the system which loaded up everything on startup To those who don't know the spec's for a NJ65 laptop, I'll provide them Processor: Intel® Pentium Dual Core @ 2.2 GHZ Video: Integrated Intel® GMA 4500MHD graphics HDD: 320GB SATA RAM: 2GB DDR2

  • Why is Silverlight so unstable? [closed]

    - by 0101
    I have never programmed in Silverlight, but I hate it. The reason is that I need it to watch videos on one of the site I watch, but like every other day I need to update the plugin. Why is Silverlight so unstable ??? they just can't get it right and I have to update that plugin all the time. P.S. I'm now thinking of somehow hacking that video stream and bypass the silverlight(so I could just throw it away). P.S. Its not updated like any other FF plugin, because its special and you need to download an exe ... pathethic.

  • Tomorrow's web development: What's the bearing?

    - by pex
    I just read a wonderful article about headaches web developers have to live with nowadays. Several questions from that article busied me for some time as well. Now I am wondering whether I missed something, whether there are approaches other than Sproutcore or Cappucino to combine the eternal detached worlds of backend and frontend. How to only write validations once? How to collect business logic in only one model? Are we heading toward a combination of CouchDB Views, NodeJS and minimalistic client-side scripts including plenty of XHR requests? Or shall we follow the direction of handling everything except the database on client side? Is everything about JavaScript? I simply ask for approaches of setting up the next web application, for best practices and promising new technologies and frameworks.
