• Force download through markup or JS

  - by mschoening

  Lets assume I have a file on a CDN (Cloud Files from Rackspace) and a static html page with a link to that file. Is there any way I can force download this file (to prevent it from opening in the browser -- for mp3s for example)? We could make our server read the file and set the corresponding header to: header("Content-Type: application/force-download") but we have about 5 million downloads per month so we would rather let the CDN take care of that. Any ideas?

• ls hangs for a certain directory

  There is a particular directory (/var/www), that when I run ls (with or without some options), the command hangs and never completes. There is only about 10-15 files and directories in /var/www. Mostly just text files. Here is some investigative info: [me@server www]$ df . Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg_dev-lv_root 50G 19G 29G 40% / [me@server www]$ df -i .

• Ajax, Lizard Brain Web Design, JSF, Struts, JavaScript, Mobile Web, Flash, jQuery, GWT, Harmony at I

  - by Kim Won

  Great Indian Developer Summit 2010 – India's Biggest Polyglot Conference and Workshops for IT Software Professionals Bangalore, April 9, 2010: The GIDS.Web Conference and Workshops has announced the complete program of over 30 sessions on how browser and rich web technologies such as AJAX, DHTML, Mashups, Web 2.0, Enterprise 2.0 technologies, and Rich UI technologies are making money and gaining market-share for some of the leading businesses in the world. The GIDS.Web track at Great Indian Developer Summit takes place 21 and 23 April 2010, at the Indian Institute of Science in Bangalore. As one of the longest running independent developer conferences in India, GIDS.Web at the Great Indian Developer Summit 2010 is uniquely positioned to provide a blend of practical, pragmatic and immediately applicable knowledge and a glimpse of the future of technology. During 21 and 23 April 2010, GIDS.Web offers a multi-track conference, workshops, expo show floor, and networking opportunities. The first keynote at GIDS.Web is led by the leading Java EE and Ajax developer, speaker, and author Marty Hall. The best of India's Java and RIA programmers have learnt the subject from Marty's seminal books Core Servlets and JavaServer Pages (first and second editions), More Servlets and JavaServer Pages, and Core Web Programming (first and second editions) from Prentice Hall and Sun Microsystems Press. Marty's keynote address is a comparison of approaches to building rich Internet applications with Ajax. Marty says Ajax development is difficult, and there are several fundamentally different strategies to building Ajaxified Web applications. The keynote address will survey the three most important of these approaches: using an Ajax-enabled JavaScript library such as jQuery, Prototype, Scriptaculous, Dojo, or Ext/JS; using a Web framework such as JSF 2.0 or Struts 2 that has integrated Ajax support; using the Google Web Toolkit (GWT) to build "pure Java" Ajax applications. The talk will compare and contrast these three approaches, discussing the types of applications that fit best for each option. Over the course of the summit Marty will conduct several more sessions on "Choosing an Ajax/JavaScript Toolkit: A Comparison of the Most Popular JavaScript Libraries", "Pure Java Ajax: An Overview of GWT 2.0", "Integrated Ajax Support in JSF 2.0" and "Ajax Support in the Prototype JavaScript Library". The second keynote by the head of Adobe's Flash initiative in India, Ramesh Srinivasaraghavan, explores the state of art in web application development and identify trends that could transform the way we create and use web applications. The talk explains how the Adobe Flash Platform has fuelled this revolution with an integrated set of technologies for delivering the most compelling applications, content and video to the widest possible audience. The Director of Forum Nokia will explain how cloud computing coupled with mobile applications enable consumers to have access to powerful services and improved user experiences never before thought possible. IEEE's 2010 President-Elect Sorel Reisman's afternoon address steps to improve the IT profession in India.

• How to monitor and maintain my grails application in live/production environment?

  - by fabien7474

  It is the first time I have ever launched live a website (with Grails web framework under Amazon EC2 platform and Cloud Foundry) and I realized quickly that I am not ready for monitoring and maintening correctly my application in production mode (fortunately the website is accessible to a very limited number of users) . The issues I have faced so far are: Cannot change my views. I need to redeploy my application I have no monitoring. I don't know who is connected, when do they sign in / sign out... Redploying my application (upload WAR + deploy) takes at least 30 minutes. I don't know how to restart my Tomcat server without a redeploy through Cloud Foundry ! ... So, my question is very simple: What tools (including grails plugins) and methods can you recommend me for taking me out from my current blindness?

• Best Application for storing code snippets

  - by Konrad

  Hi all, Just wondering if you can point me in the direction of a simple, fast program which stores code snippets. I have been using a local wiki up to now, but I find it a little annoying at times. Ideally I would like this application to be portable - i.e. it could run off of a USB stick on multiple machines with no installation. What do you guys use? EDIT: I would prefer a solution that was decoupled from the IDE and stored locally, not in the cloud. EDIT 2: Thanks for all the replies thus far, but I am still awaiting a non cloud / web based portable solution. Anyone else care to weigh in? :)

• Easiest solution to sync an offline (local desktop application) database with a central server and multiple pc's?

  - by tyfius

  I have a desktop application which uses a local database. (This can be SQLite, SqlCe, PostgreSQL or any other database I will be able to install locally, I haven't decided which one to use yet.) The plan is to achieve the following: A user can subscribe to some kind of cloud service. If he does his local database should be synced with the online database (one for all users, or one per user, whatever the easiest solution is) so he will be able to sync his local database data between multiple PC's, can access his data online. (Much like dropbox does for files.) What is the best, easiest (and preferably cheapest) solution to achieve this? I am looking into DataObjects.net but I can't find much documentation about their Sync feature. Or, are there other alternatives? For example, I start with some kind of cloud service which allows local caching and use the local caching for users who do not subscribe to the service. Any pointers, tips or experiences are welcome.

• TCP 30 small packets per second polutes connection with server

  - by Denis Ermolin

  I'm testing connection with flash client and cloud server(boost::asio for software) over TCP connection. My connection with server already is really poor - 120 ms ping in average. I found when i start to send packets with 2 bytes size (without tcp header) with speed 30 packets/s ping grow to 170-200 average. I think that it's really bad and my bad connection and bad cloud provider is reason for this high ping without any load. What do you think? (I tested my software and can compute about 50k packets/s so software is not a problem).

  I have been doing some reading and have come to the understanding that if you wish to use a launchConfig with Ubuntu you will need to install the cfn-init file yourself which I have done: "Properties" : { "KeyName" : { "Ref" : "KeyName" }, "SpotPrice" : "0.05", "ImageId" : { "Fn::FindInMap" : [ "AWSRegionArch2AMI", { "Ref" : "AWS::Region" }, { "Fn::FindInMap" : [ "AWSInstanceType2Arch", { "Ref" : "InstanceType" }, "Arch" ] } ] }, "SecurityGroups" : [ { "Ref" : "InstanceSecurityGroup" } ], "InstanceType" : { "Ref" : "InstanceType" }, "UserData" : { "Fn::Base64" : { "Fn::Join" : ["", [ "#!/bin/bash\n", "apt-get -y install python-setuptools\n", "easy_install https://s3.amazonaws.com/cloudformation-examples/aws-cfn-bootstrap-1.0-6.tar.gz\n", "cfn-init ", " --stack ", { "Ref" : "AWS::StackName" }, " --resource LaunchConfig ", " --configset ALL", " --access-key ", { "Ref" : "WorkerKeys" }, " --secret-key ", {"Fn::GetAtt": ["WorkerKeys", "SecretAccessKey"]}, " --region ", { "Ref" : "AWS::Region" }, " || error_exit 'Failed to run cfn-init'\n" ]]}} But I have a problem with this setup that I cannot seem to get a decent answer to. I keep getting this error in the logs: Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[DEBUG]: config-scripts-per-once already ran once Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[DEBUG]: handling scripts-per-boot with freq=None and args=[] Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[DEBUG]: handling scripts-per-instance with freq=None and args=[] Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[DEBUG]: handling scripts-user with freq=None and args=[] Jun 15 12:02:34 ip-0 [CLOUDINIT] cc_scripts_user.py[WARNING]: failed to run-parts in /var/lib/cloud/instance/scripts Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[WARNING]: Traceback (most recent call last):#012 File "/usr/lib/python2.7/dist-packages/cloudinit/CloudConfig/__init__.py", line 117, in run_cc_modules#012 cc.handle(name, run_args, freq=freq)#012 File "/usr/lib/python2.7/dist-packages/cloudinit/CloudConfig/__init__.py", line 78, in handle#012 [name, self.cfg, self.cloud, cloudinit.log, args])#012 File "/usr/lib/python2.7/dist-packages/cloudinit/__init__.py", line 326, in sem_and_run#012 func(*args)#012 File "/usr/lib/python2.7/dist-packages/cloudinit/CloudConfig/cc_scripts_user.py", line 31, in handle#012 util.runparts(runparts_path)#012 File "/usr/lib/python2.7/dist-packages/cloudinit/util.py", line 223, in runparts#012 raise RuntimeError('runparts: %i failures' % failed)#012RuntimeError: runparts: 1 failures Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[ERROR]: config handling of scripts-user, None, [] failed Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[DEBUG]: handling keys-to-console with freq=None and args=[] Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[DEBUG]: handling phone-home with freq=None and args=[] Jun 15 12:02:34 ip-0 [CLOUDINIT] __init__.py[DEBUG]: handling final-message with freq=None and args=[] Jun 15 12:02:34 ip-0 [CLOUDINIT] cloud-init-cfg[ERROR]: errors running cloud_config [final]: ['scripts-user'] I have absolutely no idea what scripts-user means and Google is not helping much here either. I can, when I ssh into the server, see that it runs the userdata script since I can access cfn-init as a command whereas I cannot in the original AMI the instance is made from. However I have a launchConfig: "Comment" : "Install a simple PHP application", "AWS::CloudFormation::Init" : { "configSets" : { "ALL" : ["WorkerRole"] }, "WorkerRole" : { "files" : { "/etc/cron.d/worker.cron" : { "content" : "*/1 * * * * ubuntu /home/ubuntu/worker_cron.php &> /home/ubuntu/worker.log\n", "mode" : "000644", "owner" : "root", "group" : "root" }, "/home/ubuntu/worker_cron.php" : { "content" : { "Fn::Join" : ["", [ "#!/usr/bin/env php", "<?php", "define('ROOT', dirname(__FILE__));", "const AWS_KEY = \"", { "Ref" : "WorkerKeys" }, "\";", "const AWS_SECRET = \"", { "Fn::GetAtt": ["WorkerKeys", "SecretAccessKey"]}, "\";", "const QUEUE = \"", { "Ref" : "InputQueue" }, "\";", "exec('git clone x '.ROOT.'/worker');", "if(!file_exists(ROOT.'/worker/worker_despatcher.php')){", "echo 'git not downloaded right';", "exit();", "}", "echo 'git downloaded';", "include_once ROOT.'/worker/worker_despatcher.php';" ]]}, "mode" : "000755", "owner" : "ubuntu", "group" : "ubuntu" } } } } Which does not seem to run at all. I have checked for the files existance in my home directory and it's not there. I have checked for the cronjob entry and it's not there either. I cannot, after reading through the documentation, seem to see what's potentially wrong with my code. Any thoughts on why this is not working? Am I missing something blatant?

• The Oracle Enterprise Linux Software and Hardware Ecosystem

  - by sergio.leunissen

  It's been nearly four years since we launched the Unbreakable Linux support program and with it the free Oracle Enterprise Linux software. Since then, we've built up an extensive ecosystem of hardware and software partners. Oracle works directly with these vendors to ensure joint customers can run Oracle Enterprise Linux. As Oracle Enterprise Linux is fully--both source and binary--compatible with Red Hat Enterprise Linux (RHEL), there is minimal work involved for software and hardware vendors to test their products with it. We develop our software on Oracle Enterprise Linux and perform full certification testing on Oracle Enterprise Linux as well. Due to the compatibility between Oracle Enterprise Linux and RHEL, Oracle also certifies its software for use on RHEL, without any additional testing. Oracle Enterprise Linux tracks RHEL by publishing freely downloadable installation media on edelivery.oracle.com/linux and updates, bug fixes and security errata on Unbreakable Linux Network (ULN). At the same time, Oracle's Linux kernel team is shaping the future of enterprise Linux distributions by developing technologies and features that matter to customers who deploy Linux in the data center, including file systems, memory management, high performance computing, data integrity and virtualization. All this work is contributed to the Linux and Xen communities. The list below is a sample of the partners who have certified their products with Oracle Enterprise Linux.

• Node.js Adventure - Host Node.js on Windows Azure Worker Role

  - by Shaun

  In my previous post I demonstrated about how to develop and deploy a Node.js application on Windows Azure Web Site (a.k.a. WAWS). WAWS is a new feature in Windows Azure platform. Since it’s low-cost, and it provides IIS and IISNode components so that we can host our Node.js application though Git, FTP and WebMatrix without any configuration and component installation. But sometimes we need to use the Windows Azure Cloud Service (a.k.a. WACS) and host our Node.js on worker role. Below are some benefits of using worker role. - WAWS leverages IIS and IISNode to host Node.js application, which runs in x86 WOW mode. It reduces the performance comparing with x64 in some cases. - WACS worker role does not need IIS, hence there’s no restriction of IIS, such as 8000 concurrent requests limitation. - WACS provides more flexibility and controls to the developers. For example, we can RDP to the virtual machines of our worker role instances. - WACS provides the service configuration features which can be changed when the role is running. - WACS provides more scaling capability than WAWS. In WAWS we can have at most 3 reserved instances per web site while in WACS we can have up to 20 instances in a subscription. - Since when using WACS worker role we starts the node by ourselves in a process, we can control the input, output and error stream. We can also control the version of Node.js.   Run Node.js in Worker Role Node.js can be started by just having its execution file. This means in Windows Azure, we can have a worker role with the “node.exe” and the Node.js source files, then start it in Run method of the worker role entry class. Let’s create a new windows azure project in Visual Studio and add a new worker role. Since we need our worker role execute the “node.exe” with our application code we need to add the “node.exe” into our project. Right click on the worker role project and add an existing item. By default the Node.js will be installed in the “Program Files\nodejs” folder so we can navigate there and add the “node.exe”. Then we need to create the entry code of Node.js. In WAWS the entry file must be named “server.js”, which is because it’s hosted by IIS and IISNode and IISNode only accept “server.js”. But here as we control everything we can choose any files as the entry code. For example, I created a new JavaScript file named “index.js” in project root. Since we created a C# Windows Azure project we cannot create a JavaScript file from the context menu “Add new item”. We have to create a text file, and then rename it to JavaScript extension. After we added these two files we should set their “Copy to Output Directory” property to “Copy Always”, or “Copy if Newer”. Otherwise they will not be involved in the package when deployed. Let’s paste a very simple Node.js code in the “index.js” as below. As you can see I created a web server listening at port 12345. 1: var http = require("http"); 2: var port = 12345; 3:  4: http.createServer(function (req, res) { 5: res.writeHead(200, { "Content-Type": "text/plain" }); 6: res.end("Hello World\n"); 7: }).listen(port); 8:  9: console.log("Server running at port %d", port); Then we need to start “node.exe” with this file when our worker role was started. This can be done in its Run method. I found the Node.js and entry JavaScript file name, and then create a new process to run it. Our worker role will wait for the process to be exited. If everything is OK once our web server was opened the process will be there listening for incoming requests, and should not be terminated. The code in worker role would be like this. 1: public override void Run() 2: { 3: // This is a sample worker implementation. Replace with your logic. 4: Trace.WriteLine("NodejsHost entry point called", "Information"); 5:  6: // retrieve the node.exe and entry node.js source code file name. 7: var node = Environment.ExpandEnvironmentVariables(@"%RoleRoot%\approot\node.exe"); 8: var js = "index.js"; 9:  10: // prepare the process starting of node.exe 11: var info = new ProcessStartInfo(node, js) 12: { 13: CreateNoWindow = false, 14: ErrorDialog = true, 15: WindowStyle = ProcessWindowStyle.Normal, 16: UseShellExecute = false, 17: WorkingDirectory = Environment.ExpandEnvironmentVariables(@"%RoleRoot%\approot") 18: }; 19: Trace.WriteLine(string.Format("{0} {1}", node, js), "Information"); 20:  21: // start the node.exe with entry code and wait for exit 22: var process = Process.Start(info); 23: process.WaitForExit(); 24: } Then we can run it locally. In the computer emulator UI the worker role started and it executed the Node.js, then Node.js windows appeared. Open the browser to verify the website hosted by our worker role. Next let’s deploy it to azure. But we need some additional steps. First, we need to create an input endpoint. By default there’s no endpoint defined in a worker role. So we will open the role property window in Visual Studio, create a new input TCP endpoint to the port we want our website to use. In this case I will use 80. Even though we created a web server we should add a TCP endpoint of the worker role, since Node.js always listen on TCP instead of HTTP. And then changed the “index.js”, let our web server listen on 80. 1: var http = require("http"); 2: var port = 80; 3:  4: http.createServer(function (req, res) { 5: res.writeHead(200, { "Content-Type": "text/plain" }); 6: res.end("Hello World\n"); 7: }).listen(port); 8:  9: console.log("Server running at port %d", port); Then publish it to Windows Azure. And then in browser we can see our Node.js website was running on WACS worker role. We may encounter an error if we tried to run our Node.js website on 80 port at local emulator. This is because the compute emulator registered 80 and map the 80 endpoint to 81. But our Node.js cannot detect this operation. So when it tried to listen on 80 it will failed since 80 have been used.   Use NPM Modules When we are using WAWS to host Node.js, we can simply install modules we need, and then just publish or upload all files to WAWS. But if we are using WACS worker role, we have to do some extra steps to make the modules work. Assuming that we plan to use “express” in our application. Firstly of all we should download and install this module through NPM command. But after the install finished, they are just in the disk but not included in the worker role project. If we deploy the worker role right now the module will not be packaged and uploaded to azure. Hence we need to add them to the project. On solution explorer window click the “Show all files” button, select the “node_modules” folder and in the context menu select “Include In Project”. But that not enough. We also need to make all files in this module to “Copy always” or “Copy if newer”, so that they can be uploaded to azure with the “node.exe” and “index.js”. This is painful step since there might be many files in a module. So I created a small tool which can update a C# project file, make its all items as “Copy always”. The code is very simple. 1: static void Main(string[] args) 2: { 3: if (args.Length < 1) 4: { 5: Console.WriteLine("Usage: copyallalways [project file]"); 6: return; 7: } 8:  9: var proj = args[0]; 10: File.Copy(proj, string.Format("{0}.bak", proj)); 11:  12: var xml = new XmlDocument(); 13: xml.Load(proj); 14: var nsManager = new XmlNamespaceManager(xml.NameTable); 15: nsManager.AddNamespace("pf", "http://schemas.microsoft.com/developer/msbuild/2003"); 16:  17: // add the output setting to copy always 18: var contentNodes = xml.SelectNodes("//pf:Project/pf:ItemGroup/pf:Content", nsManager); 19: UpdateNodes(contentNodes, xml, nsManager); 20: var noneNodes = xml.SelectNodes("//pf:Project/pf:ItemGroup/pf:None", nsManager); 21: UpdateNodes(noneNodes, xml, nsManager); 22: xml.Save(proj); 23:  24: // remove the namespace attributes 25: var content = xml.InnerXml.Replace("<CopyToOutputDirectory xmlns=\"\">", "<CopyToOutputDirectory>"); 26: xml.LoadXml(content); 27: xml.Save(proj); 28: } 29:  30: static void UpdateNodes(XmlNodeList nodes, XmlDocument xml, XmlNamespaceManager nsManager) 31: { 32: foreach (XmlNode node in nodes) 33: { 34: var copyToOutputDirectoryNode = node.SelectSingleNode("pf:CopyToOutputDirectory", nsManager); 35: if (copyToOutputDirectoryNode == null) 36: { 37: var n = xml.CreateNode(XmlNodeType.Element, "CopyToOutputDirectory", null); 38: n.InnerText = "Always"; 39: node.AppendChild(n); 40: } 41: else 42: { 43: if (string.Compare(copyToOutputDirectoryNode.InnerText, "Always", true) != 0) 44: { 45: copyToOutputDirectoryNode.InnerText = "Always"; 46: } 47: } 48: } 49: } Please be careful when use this tool. I created only for demo so do not use it directly in a production environment. Unload the worker role project, execute this tool with the worker role project file name as the command line argument, it will set all items as “Copy always”. Then reload this worker role project. Now let’s change the “index.js” to use express. 1: var express = require("express"); 2: var app = express(); 3:  4: var port = 80; 5:  6: app.configure(function () { 7: }); 8:  9: app.get("/", function (req, res) { 10: res.send("Hello Node.js!"); 11: }); 12:  13: app.get("/User/:id", function (req, res) { 14: var id = req.params.id; 15: res.json({ 16: "id": id, 17: "name": "user " + id, 18: "company": "IGT" 19: }); 20: }); 21:  22: app.listen(port); Finally let’s publish it and have a look in browser.   Use Windows Azure SQL Database We can use Windows Azure SQL Database (a.k.a. WACD) from Node.js as well on worker role hosting. Since we can control the version of Node.js, here we can use x64 version of “node-sqlserver” now. This is better than if we host Node.js on WAWS since it only support x86. Just install the “node-sqlserver” module from NPM, copy the “sqlserver.node” from “Build\Release” folder to “Lib” folder. Include them in worker role project and run my tool to make them to “Copy always”. Finally update the “index.js” to use WASD. 1: var express = require("express"); 2: var sql = require("node-sqlserver"); 3:  4: var connectionString = "Driver={SQL Server Native Client 10.0};Server=tcp:{SERVER NAME}.database.windows.net,1433;Database={DATABASE NAME};Uid={LOGIN}@{SERVER NAME};Pwd={PASSWORD};Encrypt=yes;Connection Timeout=30;"; 5: var port = 80; 6:  7: var app = express(); 8:  9: app.configure(function () { 10: app.use(express.bodyParser()); 11: }); 12:  13: app.get("/", function (req, res) { 14: sql.open(connectionString, function (err, conn) { 15: if (err) { 16: console.log(err); 17: res.send(500, "Cannot open connection."); 18: } 19: else { 20: conn.queryRaw("SELECT * FROM [Resource]", function (err, results) { 21: if (err) { 22: console.log(err); 23: res.send(500, "Cannot retrieve records."); 24: } 25: else { 26: res.json(results); 27: } 28: }); 29: } 30: }); 31: }); 32:  33: app.get("/text/:key/:culture", function (req, res) { 34: sql.open(connectionString, function (err, conn) { 35: if (err) { 36: console.log(err); 37: res.send(500, "Cannot open connection."); 38: } 39: else { 40: var key = req.params.key; 41: var culture = req.params.culture; 42: var command = "SELECT * FROM [Resource] WHERE [Key] = '" + key + "' AND [Culture] = '" + culture + "'"; 43: conn.queryRaw(command, function (err, results) { 44: if (err) { 45: console.log(err); 46: res.send(500, "Cannot retrieve records."); 47: } 48: else { 49: res.json(results); 50: } 51: }); 52: } 53: }); 54: }); 55:  56: app.get("/sproc/:key/:culture", function (req, res) { 57: sql.open(connectionString, function (err, conn) { 58: if (err) { 59: console.log(err); 60: res.send(500, "Cannot open connection."); 61: } 62: else { 63: var key = req.params.key; 64: var culture = req.params.culture; 65: var command = "EXEC GetItem '" + key + "', '" + culture + "'"; 66: conn.queryRaw(command, function (err, results) { 67: if (err) { 68: console.log(err); 69: res.send(500, "Cannot retrieve records."); 70: } 71: else { 72: res.json(results); 73: } 74: }); 75: } 76: }); 77: }); 78:  79: app.post("/new", function (req, res) { 80: var key = req.body.key; 81: var culture = req.body.culture; 82: var val = req.body.val; 83:  84: sql.open(connectionString, function (err, conn) { 85: if (err) { 86: console.log(err); 87: res.send(500, "Cannot open connection."); 88: } 89: else { 90: var command = "INSERT INTO [Resource] VALUES ('" + key + "', '" + culture + "', N'" + val + "')"; 91: conn.queryRaw(command, function (err, results) { 92: if (err) { 93: console.log(err); 94: res.send(500, "Cannot retrieve records."); 95: } 96: else { 97: res.send(200, "Inserted Successful"); 98: } 99: }); 100: } 101: }); 102: }); 103:  104: app.listen(port); Publish to azure and now we can see our Node.js is working with WASD through x64 version “node-sqlserver”.   Summary In this post I demonstrated how to host our Node.js in Windows Azure Cloud Service worker role. By using worker role we can control the version of Node.js, as well as the entry code. And it’s possible to do some pre jobs before the Node.js application started. It also removed the IIS and IISNode limitation. I personally recommended to use worker role as our Node.js hosting. But there are some problem if you use the approach I mentioned here. The first one is, we need to set all JavaScript files and module files as “Copy always” or “Copy if newer” manually. The second one is, in this way we cannot retrieve the cloud service configuration information. For example, we defined the endpoint in worker role property but we also specified the listening port in Node.js hardcoded. It should be changed that our Node.js can retrieve the endpoint. But I can tell you it won’t be working here. In the next post I will describe another way to execute the “node.exe” and Node.js application, so that we can get the cloud service configuration in Node.js. I will also demonstrate how to use Windows Azure Storage from Node.js by using the Windows Azure Node.js SDK.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

• Silverlight Cream for April 02, 2010 -- #828

  - by Dave Campbell

  In this Issue: Phil Middlemiss, Robert Kozak, Kathleen Dollard, Avi Pilosof, Nokola, Jeff Wilcox, David Anson, Timmy Kokke, Tim Greenfield, and Josh Smith. Shoutout: SmartyP has additional info up on his WP7 Pivot app: Preview of My Current Windows Phone 7 Pivot Work From SilverlightCream.com: A Chrome and Glass Theme - Part I Phil Middlemiss is starting a tutorial series on building a new theme for Silverlight, in this first one we define some gradients and color resources... good stuff Phil Intercepting INotifyPropertyChanged This is Robert Kozak's first post on this blog, but it's a good one about INotifyPropertyChanged and MVVM and has a solution in the post with lots of code and discussion. How do I Display Data of Complex Bound Criteria in Horizontal Lists in Silverlight? Kathleen Dollard's latest article in Visual Studio magazine is in answer to a question about displaying a list of complex bound criteria including data, child data, and photos, and displaying them horizontally one at a time. Very nice-looking result, and all the code. Windows Phone: Frame/Page navigation and transitions using the TransitioningContentControl Avi Pilosof discusses the built-in (boring) navigation on WP7, and then shows using the TransitionContentControl from the Toolkit to apply transitions to the navigation. EasyPainter: Cloud Turbulence and Particle Buzz Nokola returns with a couple more effects for EasyPainter: Cloud Turbulence and Particle Buzz ... check out the example screenshots, then go grab the code. Property change notifications for multithreaded Silverlight applications Jeff Wilcox is discussing the need for getting change notifications to always happen on the UI thread in multi-threaded apps... great diagrams to see what's going on. Tip: The default value of a DependencyProperty is shared by all instances of the class that registers it David Anson has a tip up about setting the default value of a DependencyProperty, and the consequence that may have depending upon the type. Building a “real” extension for Expression Blend Timmy Kokke's code is WPF, but the subject is near and dear to us all, Timmy has a real-world Expression Blend extension up... a search for controls in the Objects and Timelines pane ... and even if that doesn't interest you... it's the source to a Blend extension! XPath support in Silverlight 4 + XPathPad Tim Greenfield not only talks about XPath in SL4RC, but he has produced a tool, XPathPad, and provided the source... if you've used XPath, you either are a higher thinker than me(not a big stretch), or you need this :) Using a Service Locator to Work with MessageBoxes in an MVVM Application Josh Smith posted about a question that comes up a lot: showing a messagebox from a ViewModel object. This might not work for custom message boxes or unit testing. This post covers the Unit Testing aspect. Stay in the 'Light!
