• Sound stopped working

  - by Brian West

  I ran through the troubleshooting at https://help.ubuntu.com/community/SoundTroubleshooting It did not play the test sound, and it also does not play sounds during speaker-test. It does play sounds when I adjust my volume on my computer (using pommed). It worked just the other day, but this is the first time I've tested it since last night, when I put it to pm-suspend-hybrid and it half-woke up (the backlight came on, but it didn't fully wake up), then went back, then half-woke again, but was frozen like that. I had to do a manual reboot of the machine when that happened. Now my sound doesn't work, except for adjusting the volume (where the little "beep" sound plays). During the troubleshooting, it recognized my sound card, the sound modules, and the sound card's installation. I've tried removing ~/.pulse, but to no avail. Also, if it's any help, pulseaudio is running, but pulseaudio --check returns nothing, which the manpage suggests indicates an error. Edit: I should probably clarify that the wake up from the suspend-hybrid was not provoked in any way. I was laying in bed when I noticed my room was brighter suddenly, so I got up to check on it.

• Cannot copy MP3 files from a CD

  - by MountainX

  I purchased a set of spoken word audio CD's that have MP3 and FLAC audio files; I think they also play as regular audio CD's because I see a CDA directory and .cda files. But I'm only interested in playing the MP3 files by copying them to my phone. Dolphin file manager shows all the files on the CD. However, it will not copy any of them to my hard drive, which is what my goal is. Dolphin shows no error, but the copy progress is zero. Amarok will play the files but not easily. I only tried the flac files. To play a file, I click the file in Dolphin, then I have to cancel a job using KDE's notification system, then Amarok proceeds to copy the file to a tmp directory which takes a long time, then it finally plays. kb3 will rip the audio, but I would prefer to copy the files directly from the CD. Since Dolphin would not copy the files, I thought I would try the terminal, but I can't get that to work either. mount -t auto -o ro /dev/sr0 /mnt/temp that gives the error: wrong fs type, bad option, bad superblock, etc. I get the same error using -t iso9660 and -t udf. so I started troubleshooting: ~$ wodim --devices wodim: Overview of accessible drives (1 found) : ------------------------------------------------------------------------- 0 dev='/dev/sg1' rwrw-- : 'MATSHITA' 'DVD-RAM UJ8A0AS' ------------------------------------------------------------------------- /dev/sg1 is not a block device sudo file -s /dev/sr0 ERROR: cannot read /dev/sr0 (input/output error) sudo file -s /dev/sg1 just hangs How can I copy these files to my computer hard disk?

• Friday Fun: Abduction

  - by Mysticgeek

  Finally another Friday has arrived and it’s time to waste the afternoon on company time playing a flash game. Today we take a look at a fun game called Abduction.

Here is the tutorial that you can play first to get the hang of it. While you’re abducting hillbillies, they throw pitch forks and other objects at your craft so you need to avoid them.   The game has several levels to keep you distracted until quitting time.

• mpd conflicting with other applications -- taking control of pulse?

  - by Jamie Schembri

  Simple explanation If mpd is playing and sound attempts to play through another application, x, sound from x will not be output. If sound from another application, x, is playing and mpd then attempts to play, no sound will be output from mpd whilst sound from x continues to play. Details I first noticed this problem with Flash, and this continues to be the most common scenario. I posted a question about this before realising it was not strictly Flash-related, but instead is something to do with mpd. My biggest frustration comes from trying to get mpd working again, as I can't seem to pin down any method. Sometimes pulseaudio -k seems to help, other times sudo /etc/init.d/mpd restart, others killing Chromium (due to Flash) with SIGTERM. Most of the time it's a combination of the above. I think this might be because I run mpd as another user and use pulseaudio. It is not run as root or current user. Also, mpd is compiled with pulse support. I have tried numerous things, however I honestly couldn't recite what, as it has been some time since. I'd rather not go poking around without some direction, but I'd be really happy to fix this problem once and for all. mpd.conf Simplified by removing comments/blank lines. music_directory "/var/lib/mpd/music" playlist_directory "/var/lib/mpd/playlists" db_file "/var/lib/mpd/tag_cache" log_file "/var/log/mpd/mpd.log" pid_file "/var/run/mpd/pid" state_file "/var/lib/mpd/state" user "mpd" bind_to_address "wilson" input { plugin "curl" } audio_output { type "pulse" name "My Pulse Output" } filesystem_charset "UTF-8" id3v1_encoding "UTF-8" Question For the sake of keeping this a question: does anyone know what is causing this, or how to fix it?

• MMORPG design for time-limited players

  - by Philipp

  I believe that there is a significant market of players who would enjoy the exploration and interaction aspects of MMORPGs, but simply don't have the time for the endless grinding marathons which are part of the average MMORPG. MMORPGs are all about interaction between players. But when different players have different amounts of time to invest into a game, those with less time to spend will soon lack behind their power-leveling friends and won't be able to interact with them anymore. One way to solve this would be to limit the progress a player can achieve per day, so that it simply doesn't make sense to play more than one or two hours a day. But even the busiest casual players sometimes like to spend a whole sunday afternoon playing a video game. Just stopping them after two hours would be really frustrating. It also creates a pressure to use the daily progress limit every day, because otherwise the player would feel like wasting something. This pressure would be detrimental for casual gamers. What else could be done to level the playing field between those players who play 40+ hours a week and those who can't play more than 10?

• Synchronous vs. asynchronous for publish subscribe communication between JavaScript objects

  - by natlee75

  I implemented the publish subscribe pattern in a JavaScript module to be used by entirely client-side oriented JavaScript objects. This module has nothing to do with client-server communications in any way, shape or form. My question is whether it's better for the publish method in such a module to be synchronous or asynchronous, and why. As a very simplified example let's say I'm building a custom UI for an HTML5 video player widget: One of my modules is the "video" module that contains the VIDEO element and handles the various features and events associated with that element. This would probably have a namespace something like "widgets.player.video." Another is the "controls" module that has the various buttons - play, pause, volume, scrub, fullscreen, etc. This might have a namespace along the lines of "widgets.player.controls." These two modules are children of a parent "player" module ("widgets.player" ??), and as such would have no inherent knowledge of each other when instantiated as children of the "player" object. The "controls" elements would obviously need to be able to effect some changes on the video (click "Play" and the video should play), and vice versa (video's "timeUpdate" event fires and the visual display of the current time in the controls should update). I could tightly couple these modules and pass references to each other, but I'd rather take a more loosely coupled approach by setting up a pubsub type module that both can subscribe to and publish from. SO (thanks for bearing with me) in this kind of a scenario is there an advantage one way or another for synchronous publication versus asynchronous publication? I've seen some solutions posted online that allow for either/or with a boolean flag whereas others automatically do it asynchronously. I haven't personally seen an implementation that just automatically goes with synchronous publication... is this because there's no advantage to it? I know that I can accomplish this with features provided by jQuery, but it seems that there may be too much overhead involved here. The publish subscribe pattern can be implemented with relatively lightweight code designed specifically for this particular purpose so I'd rather go with that then a more general purpose eventing system like jQuery's (which I'll use for more general eventing needs :-).

• Complexity of defense AI

  - by Fredrik Johansson

  I have a non-released game, and currently it's only possible to play with another human being. As the game rules are made up by me, I think it would be great if new players could learn basic game play by playing against an AI opponent. I mean it's not like Tennis, where the majority knows at least the fundamental rules. On the other hand, I'm a bit concerned that this AI implementation can be quite complex. I hope you can help me with an complexity estimation. I've tried to summarize the gameplay below. Is this defense AI very hard to do? Basic Defense Game Play Player Defender can move within his land, i.e. inside a random, non-convex, polygon. This land will also contain obstacles modeled as polygons, that Defender has to move around. Player Attacker has also a land, modeled as another such polygon. Assume that Defender shall defend against Attacker. Attacker will then throw a thingy towards Defender's land. To be rewarded, Attacker wants to hit Defender's land, and Defender will want to strike away the thingy from his land before it stops to prevent Attacker from scoring. To feint Defender, Attacker might run around within his land before the throw, and based on these attacker movements Defender shall then continuously move to the best defense position within his land.

• XboxMP Helps You Find Multiplayer Games for the Xbox

  - by Jason Fitzpatrick

  Searching for the perfect versus or cooperative Xbox multiplayer game can be challenging–the game publisher says it plays four but what exactly does that mean? XboxMP catalogs games with detailed breakdowns of what the multiplayer experience actually entails. You can search first generation Xbox games, Xbox 360 games, and Xbox Live Arcade games with a variety of detailed criteria including the number of players it supports for local, system link, and online play (it may be a deal breaker, for example, that the only way to play the game with 4 players is to have two Xboxes or an Xbox live account). In addition to the multiplayer game data each game listing also includes addition information about the general game play including peripheral support and other features. Hit up the link below to check it out and, for more help finding multiplayer cooperative games, make sure to check out previously reviewed Co-Optimus.

• Stop animation playing automatically

  - by Starkers

  I've created an animation to animate a swinging mace. To do this I select the mace object in the scene pane, open the animation pane, and key it at a certain position at 0:00. I'm prompted to save this animation in my assets folder, which I do, as maceswing I then rotate the mace, move the slider through time and key it in a different position. I move the slider through time again, move the object to the original position and key it. There are now three things in my assets folder: maceswing appears to be my animation, but I have no idea what Mace Mace 1 and Mace 2 are. (I've been mucking around trying to get this working so it's possible Mace 1 and Mace 2 are just duplicates of Mace. I still want to know what they are though) When I play my game, the mace is constantly swinging, even though I didn't apply maceswing to it. I can't stop it. People say there's some kind of tick box to stop it constantly animating but I can't find it. My mace object only has an Animator component: Unticking this component doesn't stop the animation playing so I have no idea where the animation is coming from. Or what the Animator component actually does. I don't want this animation constantly playing. I only want it to play once when someone clicks a certain button: var Mace : Transform; if(Input.GetButtonDown('Fire1')){ Mace.animation.Play('maceswing'); }; Upon clicking the 'Fire1' button, I get this error: MissingComponentException: There is no 'Animation' attached to the "Mace" game object, but a script is trying to access it. You probably need to add a Animation to the game object "Mace". Or your script needs to check if the component is attached before using it. There is no 'Animation' attached to the "Mace" game object, and yet I can see it swinging away constantly. Infact I can't stop it! So what's causing the animation if the game object doesn't have an 'Animation' attached to it?

• Why can't I boot from portable HD?

  - by user11239

  I've been trying to get Ubuntu 10.04-LTS 32-bit desktop installed onto a 250GB FreeAgent Go drive from Seagate. I've been able to install onto a USB flash drive and boot successfully from this. I have installed Ubuntu onto the jump drive using Universal USB Installer, and this was a total success in terms of getting Ubuntu to run off a flash drive. I was unable to accomplish this with the portable HDD. I then, following instructions, attempted to install the OS onto the HDD once booted up from the flash drive. After installing the OS on the HDD, the computer would simply not load the OS when the HDD medium was selected for booting from. However, as there is no System-> Preferences-> Removable Drives and Media I could not complete this step. Is this vital? How do I do this under Ubuntu 10.04? I have formmated the MBR on the HDD and repeated the above, still with no success. I have also browsed some forums that mention there may be something related to spin-up speeds, but nothing explained in detail the issue or how to solve it, and I'm not familiar enough with system booting to understand if this could be an issue. Basically, what I'm trying to do is get Ubuntu to boot off the HDD, I've attempted several things, and the result is, after selecting the HDD from BIOS, the OS never starts booting (after waiting upwards of ten minutes). I just have a white cursor blinking. I can always get it to boot from the jump drive. Related question

• why doesn't my computer resume after sleeping overnight?

  - by bamdad

  i'm having a weird, weird bug that's been haunting me since 11.10. if i listen to music or watch a video and my computer automatically goes to sleep at night, it won't properly resume in the morning. otherwise, suspend and resume works just fine. what happens is that the wi-fi and bluetooth indicator (that turns from white to orange when suspending) stays orange, the display doesn't turn on, and the only option i have is to hard reset the machine. here's what i've tried so far: installing (and uninstalling and reinstalling) laptop-mode-tools switching the proprietary wireless driver (broadcom-wl) to the open source one (brcmsmac & bcma) and back unloading (and blacklisting) all bluetooth modules (rfcomm, btusb, bnep, bluetooth) and stopping (# stop bluetooth) and disabling (# echo 'manual' /etc/init/bluetooth.override) the bluetooth service creating a custom pm sleep action as suggested here: http://ubuntuforums.org/showthread.php?p=11926504 not watching youtube / any stuff that uses flash before going to sleep (i have flashblock, and i checked $ ps aux | grep flash) because i suspected flash to be the culprit trying out different versions of fglrx (the one from the repos, then installing the latest one from amd's site via generated .deb files, then back to the official ones) none of these worked. i remember back in the days of 10.04, there was a gconf key called network sleep: i thought about disabling that, since re-enabling the wireless card seems to be the problem (according to the indicator led), but the option appears to be missing from gnome 3 (unity-2d, whatever). does anyone have any ideas? thanks, bamdad

• How can I get my first-person character in Unity to move to a ledge with an animation?

  - by BallzOfSteel

  I'm trying to get this to happen: The character walks up to a large crate, the player presses a button, and an animation starts playing where the character climbs up on to the crate. (all in first person view). So far I tried this with normal "First Person Controller" Prefab in Unity. My code so far: function OnTriggerStay(other : Collider){ if(other.tag == "GrabZone"){ if(Input.GetKeyDown("e")){ animation.Play("JumpToLedge"); } } } However when i use this on The FPC it will always play from the position the animation is created on. I also tried to create an empty game object, placing the FPC in there. Gives same effect. I also tried just animating the graphics of the FPC alone. This seems to work but since the Character Controller itself is not animated that stays onthe ground. So the whole FPC wont work anymore. Is there anyway i could let this animation play on the local position the player is on at that time? Or can you think of any other logical solution for a grab and climb?

• cannot boot ubuntu 13.10 with my usb, Can i change the kernal on my laptop to run it?

  Currently i am running 12.04 and looking for an upgrade to 13.10 I first tried a bootable 64bit usb and failed. With the message saying "Kernal requires an x86-64 CPU but only detected an I686 CPU Unable to boot please use a kernal appropriate for your CPU" then tried 32bit and same message came up.

• how do I fix 12.04 which has crashed after the latest update

  - by user70261

  I added a new drive to my system because the old one was full and stopped. I installed 12.04 at the same time, onto the new drive using a flash disk while off line. The system performs fine on 12.04 from the flash disk and it booted from the new drive OK and I was able to recover all my old data. The updater suggested that I update, so I went ahead and did so. At the end of which it wanted to reboot. I went ahead but on reboot I get to the log in prompt and then the whole system crashes. It tries to recover and then performs a bug report during which it tells me that a whole bunch of files are out of date (these would be the new ones I just updated!) and the screen goes black. Game over. I've tried to reboot several times ... same result. I can boot off the flash drive OK. How do I restore the system I had before the update, without over writing all my hard earned recovered data? Or how do I identify the "new updates" that are causing me grief?

• scalacheck/scalatest not found: how to add it in sbt/scala?

  - by Pavel Reich

  I've installed typesafe-stack from http://typesafe.com/stack/download on my ubuntu12, than I created a play project (g8 typesafehub/play-scala) and now I want to add scalatest or scalacheck to my project. So my_app/project/plugins.sbt has the following lines: // The Typesafe repository resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/" // Use the Play sbt plugin for Play projects addSbtPlugin("play" % "sbt-plugin" % "2.0.1") Then I added scalatest using addSbtPlugin: addSbtPlugin("org.scalatest" %% "scalatest" % "2.0.M1" % "test") and now it fails with the following message when I run 'sbt test' [info] Resolving org.scalatest#scalatest;2.0.M1 ... [warn] module not found: org.scalatest#scalatest;2.0.M1 [warn] ==== typesafe-ivy-releases: tried [warn] http://repo.typesafe.com/typesafe/ivy-releases/org.scalatest/scalatest/scala_2.9.1/sbt_0.11.3/2.0.M1/ivys/ivy.xml [warn] ==== local: tried [warn] ~/.ivy2/local/org.scalatest/scalatest/scala_2.9.1/sbt_0.11.3/2.0.M1/ivys/ivy.xml [warn] ==== Typesafe repository: tried [warn] http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1_0.11.3/2.0.M1/scalatest-2.0.M1.pom [warn] ==== typesafe-ivy-releases: tried [warn] http://repo.typesafe.com/typesafe/ivy- releases/org.scalatest/scalatest/scala_2.9.1/sbt_0.11.3/2.0.M1/ivys/ivy.xml [warn] ==== public: tried [warn] http://repo1.maven.org/maven2/org/scalatest/scalatest_2.9.1_0.11.3/2.0.M1/scalatest-2.0.M1.pom What I don't understand: why does it use this http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1_0.11.3/2.0.M1/scalatest-2.0.M1.pom URL instead of the real one http://repo.typesafe.com/typesafe/releases/org/scalatest/scalatest_2.9.1/2.0.M1/scalatest_2.9.1-2.0.M1.pom? Quite the same problem I have with scalacheck: it also tries to download using sbt-version specific artifactId whereas the repository has only scala-version specific. What am I doing wrong? I understand there must be a switch in sbt somewhere, not to use sbt-version as part of the artifact URL? I also tried using this in my plugins.sbt libraryDependencies += "org.scalatest" %% "scalatest" % "2.0.M1" % "test" but looks like it is completely ignored by sbt and scalatest.jar hasn't appeared in the classpath: my_app/test/AppTest.scala:1: object scalatest is not a member of package org [error] import org.scalatest.FunSuite because the output of sbt clean && sbt test has lots of Resolving org.easytesting#fest-util;1.1.6 or just another library, but nothing about scalatest. I use scala 2.9.1 and sbt 0.11.3, trying to use scalatest 2.0.M1 and 1.8; scalacheck: resolvers ++= Seq( "snapshots" at "http://oss.sonatype.org/content/repositories/snapshots", "releases" at "http://oss.sonatype.org/content/repositories/releases" ) libraryDependencies ++= Seq( "org.scalacheck" %% "scalacheck" % "1.9" % "test" ) With the same outcome, i.e. it uses the sbtVersion specific POM URL, which doesn't exist. What am I doing wrong? Thanks.

• Animating gradient displays line artifacts in ActionScript

  - by TheDarkIn1978

  i've programatically created a simple gradient (blue to red) sprite rect using my own basic class called GradientRect, but moving or animation the sprite exhibits line artifacts. when the sprite is rotating, it kind of resembles bad reception of an old television set. i'm almost certain the cause is because each line slice of the gradient is vector so there are gaps between the lines - this is visible when the sprite is zoomed in. var colorPickerRect:GradientRect = new GradientRect(200, 200, 0x0000FF, 0xFF0000); addChild(colorPickerRect); colorPickerRect.cacheAsBitmap = true; colorPickerRect.x = colorPickerRect.y = 100; colorPickerRect.addEventListener(Event.ENTER_FRAME, rotate); function rotate(evt:Event):void { evt.target.rotation += 1; } ________________________ //CLASS PACKAGE package { import flash.display.CapsStyle; import flash.display.GradientType; import flash.display.LineScaleMode; import flash.display.Sprite; import flash.geom.Matrix; public class GradientRect extends Sprite { public function GradientRect(gradientRectWidth:Number, gradientRectHeight:Number, ...leftToRightColors) { init(gradientRectWidth, gradientRectHeight, leftToRightColors); } private function init(gradientRectWidth:Number, gradientRectHeight:Number, leftToRightColors:Array):void { var leftToRightAlphas:Array = new Array(); var leftToRightRatios:Array = new Array(); var leftToRightPartition:Number = 255 / (leftToRightColors.length - 1); var pixelColor:Number; var i:int; //Push arrays for (i = 0; i < leftToRightColors.length; i++) { leftToRightAlphas.push(1); leftToRightRatios.push(i * leftToRightPartition); } //Graphics matrix and lineStyle var leftToRightColorsMatrix:Matrix = new Matrix(); leftToRightColorsMatrix.createGradientBox(gradientRectWidth, 1); graphics.lineStyle(1, 0, 1, false, LineScaleMode.NONE, CapsStyle.NONE); for (i = 0; i < gradientRectWidth; i++) { graphics.lineGradientStyle(GradientType.LINEAR, leftToRightColors, leftToRightAlphas, leftToRightRatios, leftToRightColorsMatrix); graphics.moveTo(i, 0); graphics.lineTo(i, gradientRectHeight); } } } } how can i solve this problem?

• Stubbing a before_filter with RSpec

  - by TheDelChop

  Guys, I'm having trouble understanding why I can't seem to stub this controller method :load_user, since all of my tests fail if I change the actual implementation of :load_user to not return and instance of @user. Can anybody see why my stub (controller.stub!(:load_user).and_return(@user)) seems to fail to actually get called when RSpec makes a request to the controller? require 'spec_helper' describe TasksController do before(:each) do @user = Factory(:user) sign_in @user @task = Factory(:task) User.stub_chain(:where, :first).and_return(@user) controller.stub!(:load_user).and_return(@user) end #GET Index describe "GET Index" do before(:each) do @tasks = 7.times{Factory(:task, :user = @user)} @user.stub!(:tasks).and_return(@tasks) end it "should should find all of the tasks owned by a user" do @user.should_receive(:tasks).and_return(@tasks) get :index, :user_id = @user.id end it "should assign all of the user's tasks to the view" do get :index, :user_id = @user.id assigns[:tasks].should be(@tasks) end end #GET New describe "GET New" do before(:each) do @user.stub_chain(:tasks, :new).and_return(@task) end it "should return a new Task" do @user.tasks.should_receive(:new).and_return(@task) get :new, :user_id = @user.id end end #POST Create describe "POST Create" do before(:each) do @user.stub_chain(:tasks, :new).and_return(@task) end it "should create a new task" do @user.tasks.should_receive(:new).and_return(@task) post :create, :user_id = @user.id, :task = @task.to_s end it "saves the task" do @task.should_receive(:save) post :create, :user_id = @user.id, :task = @task end context "when the task is saved successfully" do before(:each) do @task.stub!(:save).and_return(true) end it "should set the flash[:notice] message to 'Task Added Successfully'"do post :create, :user_id = @user.id, :task = @task flash[:notice].should == "Task Added Successfully!" end it "should redirect to the user's task page" do post :create, :user_id = @user.id, :task = @task response.should redirect_to(user_tasks_path(@user.id)) end end context "when the task isn't saved successfully" do before(:each) do @task.stub(:save).and_return(false) end it "should return to the 'Create New Task' page do" do post :create, :user_id = @user.id, :task = @task response.should render_template('new') end end end it "should attempt to authenticate and load the user who owns the tasks" do context "when the tasks belong to the currently logged in user" do it "should set the user instance variable to the currently logged in user" do pending end end context "when the tasks belong to another user" do it "should set the flash[:notice] to 'Sorry but you can't view other people's tasks.'" do pending end it "should redirect to the home page" do pending end end end end class TasksController < ApplicationController before_filter :load_user def index @tasks = @user.tasks end def new @task = @user.tasks.new end def create @task = @user.tasks.new if @task.save flash[:notice] = "Task Added Successfully!" redirect_to user_tasks_path(@user.id) else render :action => 'new' end end private def load_user if current_user.id == params[:user_id].to_i @user = User.where(:id => params[:user_id]).first else flash[:notice] = "Sorry but you can't view other people's tasks." redirect_to root_path end end end Can anybody see why my stub doesnt' work? Like I said, my tests only pass if I make sure that load_user works, if not, all my tests fail which makes my think that RSpec isn't using the stub I created. Thanks, Joe

• A standard event messaging system with AJAX?

  - by Gutzofter

  Is there any standards or messaging framework for AJAX? Right now I have a single page that loads content using Ajax. Because I had a complex form for data entry as part of my content, I need to validate certain events that can occur in my form. So after some adjustments driven by my tests: asyncShould("search customer list click", 3, function() { stop(1000); $('#content').show(); var forCustomerList = newCustomerListRequest(); var forShipAndCharge = newShipAndChargeRequest(forCustomerList); forCustomerList.page = '../../vt/' + forCustomerList.page; forShipAndCharge.page = 'helpers/helper.php'; forShipAndCharge.data = { 'action': 'shipAndCharge', 'DB': '11001' }; var originalComplete = forShipAndCharge.complete; forShipAndCharge.complete = function(xhr, status) { originalComplete(xhr, status); ok($('#customer_edit').is(":visible"), 'Shows customer editor'); $('#search').click(); ok($('#customer_list').is(":visible"), 'Shows customer list'); ok($('#customer_edit').is(":hidden"), 'Does not show customer editor'); start(); }; testController.getContent(forShipAndCharge); }); Here is the controller for getting content: getContent: function (request) { $.ajax({ type: 'GET', url: request.page, dataType: 'json', data: request.data, async: request.async, success: request.success, complete: request.complete }); }, And here is the request event: function newShipAndChargeRequest(serverRequest) { var that = { serverRequest: serverRequest, page: 'nodes/orders/sc.php', data: 'customer_id=-1', complete: errorHandler, success: function(msg) { shipAndChargeHandler(msg); initWhenCustomer(that.serverRequest); }, async: true }; return that; } And here is a success handler: function shipAndChargeHandler(msg) { $('.contentContainer').html(msg.html); if (msg.status == 'flash') { flash(msg.flash); } } And on my server side I end up with a JSON structure that looks like this: $message['status'] = 'success'; $message['data'] = array(); $message['flash'] = ''; $message['html'] = ''; echo json_encode($message); So now loading content consists of two parts: HTML, this is the presentation of the form. DATA, this is any data that needs be loaded for the form FLASH, any validation or server errors STATUS tells client what happened on server. My question is: Is this a valid way to handle event messaging on the client-side or am I going down a path of heartache and pain?

• Silverlight Cream for December 12, 2010 -- #1008

  - by Dave Campbell

  In this Issue: Michael Washington, Samuel Jack, Alfred Astort(-2-), Nokola(-2-), Avi Pilosof, Chris Klug, Pete Brown, Laurent Bugnion(-2-), and Jaime Rodriguez(-2-, -3-). Above the Fold: Silverlight: "Sharing resources and styles between projects in Silverlight" Chris Klug WP7: "Windows Phone Application Performance at Silverlight Firestarter" Jaime Rodriguez Training: "Silverlight View Model (MVVM) - A Play In One Act" Michael Washington Shoutouts: Koen Zwikstra announced the availability of the first Silverlight Spy 4 Preview 1 Gavin Wignall announced the Launch of Festive game built with Silverlight 4, hosted on Azure ... free to play. From SilverlightCream.com: Silverlight View Model (MVVM) - A Play In One Act Michael Washington has an interesting take on writing a blog post with this 'play' version of Silverlight View Models and Expression Blend with a heaping dose of Behaviors added in for flavoring. Build a Windows Phone Game in 3 days – Day 1 Samuel Jack is attempting to build a WP7 game in 3 days including downloading the tools and an XNA book... interesting to see where he's headed wth this venture. 4 of 10 - Make sure your finger can hit the target and text is legible Continuing with a series of tips from the folks reviewing apps for the marketplace via Alfred Astort is this number 4 -- touch target size and legible text. 5 of 10 - Give feedback on touch and progress within your UI Alfred Astort's number 5 is also up, and continues the touch discussion with this tip about giving the user feedback on their touch. Fantasia Painter Released for Windows Phone 7 + Tips Nokola took the release of his Fantasia Painter on WP& as an opportunity not only to blog about the fact that we can go buy it, but has a blog full of hints and tips that he gathered while working on it. Games for Windows Phone 7 Resources: Reducing Load Times, RPG Kit; Other Nokola also blogged about the release of the new games education pack, and gives up the cursor he uses in his videos after being asked... The simplest way to do design-time ViewModels with MVVM and Blend. Avi Pilosof attacks the design-time ViewModel issue in Blend with a 'no code' solution. Sharing resources and styles between projects in Silverlight Chris Klug is talking about sharing resources and styles across a large Silverlight project... near and dear to my heart at this moment. Dynamically Generating Controls in WPF and Silverlight Pete Brown has a post up that's generated some interest... creating controls at runtime... and he's demonstrating several different ways for both Silverlight and WPF #twitter for Windows Phone 7 protips (#wp7) Laurent Bugnion was posting these great tips for Twitter for WP7 and rolled all 16 of them up into a blog post... check them and the app out... Increasing touch surface (#wp7dev) Laurent Bugnion's most current post should be of great interest to WP7 devs... providing more touch surface for your user's fat fingers, err, I mean their fat fingerings :) ... great information and samples ... and interesting it is a fail point as listed by Alfred Astort above. Windows Phone Application Performance at Silverlight Firestarter This material from Jaime Rodriguez actually hit prior to his Firestarter presentation, but should be required reading for anyone doing a WP7 app... great Performance tips from the trenches... slide deck, cheat-sheet, and code. UpdateSourceTrigger on Windows Phone data bindings Another post from Jaime Rodriguez actually went through a couple revisions already.. how about a WP7 TextBox that fires notifications to the ViewModel when the text changes? ... would you like a behavior with that? Details on the Push Notification app limits Jaime Rodriguez has yet another required reading post up on Push Notification limits ... what it really entails and how you can be a good WP7 citizen by the way you program your app. Stay in the 'Light!
