  • NASA’s can alert you when Space Station is visible from your backyard

    - by Gopinath
    NASA’s International Space Station(ISS) is the third most brightest object visible in the sky after Sun and Moon. If we know exactly when to look up, we will be able to spot Space Station with naked eye and it looks like bright star moving.  On the occasion of 12th anniversary of astronauts living in space station, NASA started a free services dubbed as Spot The Station, that alerts you when Space Station is visible from your backyard. Those who sign up with the free service by providing location details will get an email & text alerts couple of hours in advance so that they can have a glimpse of space station. Here is a sample alert sent to registered users SpotTheStation! Time: Wed Apr 25 7:45 PM, Visible: 4 min, Max Height: 66 degrees, Appears: WSW, Disappears NE. The space station is typically visible right at early morning or evenings when moon is the only one brightest star visible in the sky. The service is available world wide and almost 90 percent of the population on earth would be able to see clearly without using any fancy equipment. Follow the link spotthestation.nasa.gov to register for alerts. Flickr cc image: slideshow bob

  • Talking JavaOne with Rock Star Simon Ritter

    - by Janice J. Heiss
    Oracle’s Java Technology Evangelist Simon Ritter is well known at JavaOne for his quirky and fun-loving sessions, which, this year include: CON4644 -- “JavaFX Extreme GUI Makeover” (with Angela Caicedo on how to improve UIs in JavaFX) CON5352 -- “Building JavaFX Interfaces for the Real World” (Kinect gesture tracking and mind reading) CON5348 -- “Do You Like Coffee with Your Dessert?” (Some cool demos of Java of the Raspberry Pi) CON6375 -- “Custom JavaFX Charts: (How to extend JavaFX Chart controls with some interesting things) I recently asked Ritter about the significance of the Raspberry Pi, the topic of one of his sessions that consists of a credit card-sized single-board computer developed in the UK with the intention of stimulating the teaching of basic computer science in schools. “I don't think there's one definitive thing that makes the RP significant,” observed Ritter, “but a combination of things that really makes it stand out. First, it's the cost: $35 for what is effectively a completely usable computer. OK, so you have to add a power supply, SD card for storage and maybe a screen, keyboard and mouse, but this is still way cheaper than a typical PC. The choice of an ARM processor is also significant, as it avoids problems like cooling (no heat sink or fan) and can use a USB power brick.  Combine these two things with the immense groundswell of community support and it provides a fantastic platform for teaching young and old alike about computing, which is the real goal of the project.”He informed me that he’ll be at the Raspberry Pi meetup on Saturday (not part of JavaOne). Check out the details here.JavaFX InterfacesWhen I asked about how JavaFX can interface with the real world, he said that there are many ways. “JavaFX provides you with a simple set of programming interfaces that can create complex, cool and compelling user interfaces,” explained Ritter. “Because it's just Java code you can combine JavaFX with any other Java library to provide data to display and control the interface. What I've done for my session is look at some of the possible ways of doing this using some of the amazing hardware that's available today at very low cost. The Kinect sensor has added a new dimension to gaming in terms of interaction; there's a Java API to access this so you can easily collect skeleton tracking data from it. Some clever people have also written libraries that can track gestures like swipes, circles, pushes, and so on. We use these to control parts of the UI. I've also experimented with a Neurosky EEG sensor that can in some ways ‘read your mind’ (well, at least measure some of the brain functions like attention and meditation).  I've written a Java library for this that I include as a way of controlling the UI. We're not quite at the stage of just thinking a command though!” Here Comes Java EmbeddedAnd what, from Ritter’s perspective, is the most exciting thing happening in the world of Java today? “I think it's seeing just how Java continues to become more and more pervasive,” he said. “One of the areas that is growing rapidly is embedded systems.  We've talked about the ‘Internet of things’ for many years; now it's finally becoming a reality. With the ability of more and more devices to include processing, storage and networking we need an easy way to write code for them that's reliable, has high performance, and is secure. Java fits all these requirements. With Java Embedded being a conference within a conference, I'm very excited about the possibilities of Java in this space.”Check out Ritter’s sessions or say hi if you run into him.

  • LLBLGen Pro and JSON serialization

    - by FransBouma
    I accidentally removed a reply from my previous blogpost, and as this blog-engine here at weblogs.asp.net is apparently falling apart, I can't re-add it as it thought it would be wise to disable comment controls on all posts, except new ones. So I'll post the reply here as a quote and reply on it. 'Steven' asks: What would the future be for LLBLGen Pro to support JSON for serialization? Would it be worth the effort for a LLBLGenPro user to bother creating some code templates to produce additional JSON serializable classes? Or just create some basic POCO classes which could be used for exchange of client/server data and use DTO to map these back to LLBGenPro ones? If I understand the work around, it is at the expense of losing xml serialization. Well, as described in the previous post, to enable JSON serialization, you can do that with a couple of lines and some attribute assignments. However, indeed, the attributes might make the XML serialization not working, as described in the previous blogpost. This is the case if the service you're using serializes objects using the DataContract serializer: this serializer will give up to serialize the entity objects to XML as the entity objects implement IXmlSerializable and this is a no-go area for the DataContract serializer. However, if your service doesn't use a DataContract serializer, or you serialize the objects manually to Xml using an xml serializer, you're fine. When you want to switch to Xml serializing again, instead of JSON in WebApi, and you have decorated the entity classes with the data-contract attributes, you can switch off the DataContract serializer, by setting a global configuration setting: var xml = GlobalConfiguration.Configuration.Formatters.XmlFormatter; xml.UseXmlSerializer = true; This will make the WebApi use the XmlSerializer, and run the normal IXmlSerializable interface implementation.

  • How to get over “Did I lock the door?” syndrome

    - by Boonei
    I am person who always asks myself  ”Did I lock the house door?”,  And I do ask that question when I have almost reached office. I don’t have a bad memory or I am not a “forget it all after a min person”. Infact I have a fantastic memory of things. This problem has been haunting me for a very long time. My wife used to always have a angry face after we had get down from the car. Because after we have walked for about 20 yards I would run back to the car to check if I had locked the car, you see this problem exists for all locked objects. This happens everyday all round the year. Now a days I don’t have the problem ! I did not get the solution from any doctor or any book that that talks about my inner mind. It was a practical advice given by my aunt….. When I told her that I had this problem, she smiled and said its very very easy to get around this. I was stunned. The solution she gave me was simple. After I had locked the door, should hold the lock and look at it for 5 sec and say to myself   “I have locked the door”. Believe me it works like a charm. The reason why it works is my aunt goes to explain, that your mind always thinks twice of important things that we do on our daily life and raises doubts after sometime. The only way to stop is it by looking at it, holding it and telling yourself that its ok and its done. This holds good for all the things that you generally doubt like, did I turn off the AC?, did I turn off the lights in the house when I left?. Just look at it for 5 sec, hold it tell yourself its done. You will not look back.

  • Dude, what’s up with POP Forums vNext?

    - by Jeff
    Yeah, it has been awhile. I posted v9.2 back in January, about five months ago. That’s a real change from the release pace I had there for awhile. Let me explain what’s going on. First off, in the interim, I re-launched CoasterBuzz, which required a lot of my attention for about two of those months. That’s a good thing though, because that site is just about the best test bed I could ask for. The other thing is that I committed to make the next version use ASP.NET MVC 4, which is now at the RC stage. I didn’t think much about when they’d hit their RTW point, but RC is good enough for me. To that end, there is enough change in the next version that I recently decided to make it a major version upgrade, and finish up the loose ends and science projects to make it whole. Here’s what’s in store… Mobile views: I sat on this or a long time. Originally, I was going to use jQuery Mobile, and waited and waited for a new release, but in the end, decided against using it. Sometimes buttons would unexplainably not work, I felt like I was fighting it at times, and the CSS just felt too heavy. I rolled my own mobile sugar at a fraction of the size, and I think you’ll find it easy to modify. And it’s Metro-y, of course! Re-do of background services: A number of things run in the background, and I did quite a bit of “reimagining” of that code. It’s the weirdness of running services in a Web site context, because so many folks can’t run a bona fide service on their host’s box. The biggest change here is that these service no longer start up by default. You’ll need to call a new method from global.asax called PopForumsActivation.StartServices(). This is also a precursor to running the app in a Web farm (new data layer and caching is the second part of that). I learned about this the hard way when I had three apps using the forum library code but only one was actually the forum. The services were all running three times as often with race conditions and hits on the same data. That was particularly bad for e-mail. CSS clean up: It’s still not ideal, but it’s getting better. That’s one of those things that comes with integrating to a real site… you discover all of the dumb things you did. The mobile CSS is particularly easier to live with. Bug fixes: There are a whole lot of them. Most were minor, but it’s feeling pretty solid now. So that’s where I am. I’m going to call it v10.0, and I’m going to really put forth some effort toward finishing the mobile experience and getting through the remaining bugs. The roadmap beyond that will likely not be feature oriented, but rather work on some other things, like making it run in Azure, perhaps using SQL CE, a better install experience, etc. As usual, I’ll post the latest here. Stay tuned!

  • Integrate Microsoft Translator into your ASP.Net application

    - by sreejukg
    In this article I am going to explain how easily you can integrate the Microsoft translator API to your ASP.Net application. Why we need a translation API? Once you published a website, you are opening a channel to the global audience. So making the web content available only in one language doesn’t cover all your audience. Especially when you are offering products/services it is important to provide contents in multiple languages. Users will be more comfortable when they see the content in their native language. How to achieve this, hiring translators and translate the content to all your user’s languages will cost you lot of money, and it is not a one time job, you need to translate the contents on the go. What is the alternative, we need to look for machine translation. Thankfully there are some translator engines available that gives you API level access, so that automatically you can translate the content and display to the user. Microsoft Translator API is an excellent set of web service APIs that allows developers to use the machine translation technology in their own applications. The Microsoft Translator API is offered through Windows Azure market place. In order to access the data services published in Windows Azure market place, you need to have an account. The registration process is simple, and it is common for all the services offered through the market place. Last year I had written an article about Bing Search API, where I covered the registration process. You can refer the article here. http://weblogs.asp.net/sreejukg/archive/2012/07/04/integrate-bing-search-api-to-asp-net-application.aspx Once you registered with Windows market place, you will get your APP ID. Now you can visit the Microsoft Translator page and click on the sign up button. http://datamarket.azure.com/dataset/bing/microsofttranslator As you can see, there are several options available for you to subscribe. There is a free version available, great. Click on the sign up button under the package that suits you. Clicking on the sign up button will bring the sign up form, where you need to agree on the terms and conditions and go ahead. You need to have a windows live account in order to sign up for any service available in Windows Azure market place. Once you signed up successfully, you will receive the thank you page. You can download the C# class library from here so that the integration can be made without writing much code. The C# file name is TranslatorContainer.cs. At any point of time, you can visit https://datamarket.azure.com/account/datasets to see the applications you are subscribed to. Click on the Use link next to each service will give you the details of the application. You need to not the primary account key and URL of the service to use in your application. Now let us start our ASP.Net project. I have created an empty ASP.Net web application using Visual Studio 2010 and named it Translator Sample, any name could work. By default, the web application in solution explorer looks as follows. Now right click the project and select Add -> Existing Item and then browse to the TranslatorContainer.cs. Now let us create a page where user enter some data and perform the translation. I have added a new web form to the project with name Translate.aspx. I have placed one textbox control for user to type the text to translate, the dropdown list to select the target language, a label to display the translated text and a button to perform the translation. For the dropdown list I have selected some languages supported by Microsoft translator. You can get all the supported languages with their codes from the below link. http://msdn.microsoft.com/en-us/library/hh456380.aspx The form looks as below in the design surface of Visual Studio. All the class libraries in the windows market place requires reference to System.Data.Services.Client, let us add the reference. You can find the documentation of how to use the downloaded class library from the below link. http://msdn.microsoft.com/en-us/library/gg312154.aspx Let us evaluate the translatorContainer.cs file. You can refer the code and it is self-explanatory. Note the namespace name used (Microsoft), you need to add the namespace reference to your page. I have added the following event for the translate button. The code is self-explanatory. You are creating an object of TranslatorContainer class by passing the translation service URL. Now you need to set credentials for your Translator container object, which will be your account key. The TranslatorContainer support a method that accept a text input, source language and destination language and returns DataServiceQuery<Translation>. Let us see this working, I just ran the application and entered Good Morning in the Textbox. Selected target language and see the output as follows. It is easy to build great translator applications using Microsoft translator API, and there is a reasonable amount of translation you can perform in your application for free. For enterprises, you can subscribe to the appropriate package and make your application multi-lingual.

  • Launch Webcast Q&A: Oracle WebCenter Suite 11g - The Platform for the Modern User Experience

    - by howard.beader(at)oracle.com
    Did you have a chance to watch the Oracle WebCenter Suite 11g Launch Webcast yet? Andy MacMillan presented some great information on the webcast and answered quite a few of your questions in the Q&A session as well. For your reading pleasure we have captured a number of the questions and answers and they are summarized below: Question: Can you tell me what should our Portal strategy be for integrating and extending our Oracle enterprise applications? Answer: We recommend that you look at this in two steps, the first would be to ensure that you have a good understanding of our common user experience architecture. Internally our product teams at Oracle are already investing in this quite heavily today for Fusion Applications and this is driving natural convergence from a UX strategy standpoint. The second step would be to look at how best to componentize the back office applications so that the business users across your organization can take advantage of these -- don't make it just about putting a new skin on top of what you already have from an application standpoint, instead look at how best to embed the social computing capabilities as part of the solution for your business users. Question: We are currently using the BEA WebLogic Portal now, should we stay on WLP or should we be looking at moving to WebCenter or when should we move to WebCenter? Answer: Our strategy has been called "Continue & Converge", this theme means that you can continue to use WebLogic or Plumtree portals until your organization is ready to move to WebCenter and in the mean time you can continue to deploy what you need to in your organization of WLP or WCI Portals with the full support of Oracle. In addition WebCenter Services can be leveraged for social computing to complement what you are already doing today and enable your organization to take advantage of some of the latest and greatest social computing capabilities. We have migration scripts and conversion capabilities available as well as programs where Oracle can help you evaluate your options to decide how best to move forward. WebCenter provides the best of the best capabilities and will enable you to take advantage of new capabilities that may not exist in your current portal today. In the end though it's up to you as a customer as to when you want to make the transition to Oracle WebCenter Suite. Question: Can you tell me how is Oracle leveraging WebCenter internally and for its Application and Middleware product UX strategies? Answer: Internally, Oracle is leveraging WebCenter for our employees and thus far we are seeing significant updates with our users taking advantage of the business activity streams, team spaces and collaboration capabilities. From a product strategy standpoint, our product teams are taking advantage of the common user experience architecture and leveraging WebCenter to provide social and collaborative capabilities to the Oracle Applications and providing new types of composite applications with what is coming with Fusion Applications. WebCenter also provides a common user experience across all the products in the Oracle Fusion Middleware family as well. Question: Our organization is currently using SharePoint, but we are also an Oracle Applications customer, how should we be thinking about WebCenter as we move forward? Answer: Great question. Typically, we are seeing organizations using SharePoint for its core use cases of small team collaboration and file server replacement. WebCenter can connect to SharePoint as a content source to feed into WebCenter quite easily and it leverages the robust Oracle ECM product under WebCenter as well. In addition, SharePoint team sites can be connected to WebCenter utilizing our SharePoint connector. With Oracle WebCenter though, we are really targeting business users and enterprise applications, thus affecting positive change on the processes that drive the business to improve productivity across your organization. Question: Are organizations today using WebCenter as a Web platform for externally facing public websites? Answer: Yes, we are seeing a convergence around web content management and portal types of websites with customers converting them from just broadcasting content to making it a much richer personalized experience and also exposing back-office applications as well. Web Content Management capabilities are already embedded in WebCenter so that organizations can take advantage now of the benefits a personalized web experience provides for your customers. This is simply a short summary of a few of the questions addressed on the webcast, please tune in now to learn more about Oracle WebCenter, the user experience platform for the enterprise and the web! The Oracle WebCenter Suite 11g Launch Webcast can be found here

  • Thoughts on the new JavaFX by Jim Connors

    - by Jacob Lehrbaum
    First, a brief editorial if I may.  The upcoming JavaFX 2.0 platform has been getting overwhelmingly positive reaction from the community so far.  While the public sentiment seems to be cautiously optimistic, I've heard nothing but positive reactions from everyone that I've spoken to about the platform.   In fact, many of the early adopters of JavaFX have told us directly that they are very encouraged about the direction the platform is taking.One such early adopter is Oracle's own Jim Connors.  As his day job, Jim is a principal sales consultant (basically an engineer that supports Oracle's sales efforts) in the New York area.  However, Jim also co-wrote a book with Jim Clarke and Eric Bruno on JavaFX and has spoken and conducted training sessions at events like the New York Java Developer Day, the Java Road Trip, and other events.In his thoughtful editorial, Jim discusses some of the reasons why he believes the new directions Oracle is taking JavaFX make sense, including:Better developer toolsLower barriers to adoption -> better accessibility to existing Java developersImproved performanceMore flexibility (ability to use other dynamic languages, etc)To read more about Jim's thoughts on the new JavaFX, check out his blog.  Or if you want to learn more about the JavaFX platform, pick up a copy of his book.  And if you still want to use JavaFX Script, you can check out Project Visage

  • Devoxx 2011 Trip Report + Pictures

    - by arungupta
    3350 attendees from 40 countries lived in "paradise" for 5 days last week. This paradise had 170+ rock star speakers delivering 200+ hours of technical content in about 150 sessions. And it truly was a paradise with a clear differentiation from other Java conferences. There were several Oracle speakers at the paradise covering the entire gamut of Java platform. I delivered a Java EE 6 hands-on lab (new content), showcased Java EE 7 and GlassFish 4.0 early work at the keynote, and participated in a panel to talk about Contexts and Dependency Injection. The demo in the keynote showed how to deploy a Java EE application in a managed environment. The demo showed a Conference Planner application that can be used by conference organizers to display sessions, tracks, and speaker information. This same application can be deployed and display data from JavaOne 2011 or Devoxx 2011 based upon the SQL chosen for database initialization. If javaone-sf-2011.sql is chosen for datbase initialization then the application looks like as shown: If devoxx-2011.sql is chosen then the application looks like as shown: And of course, clicking on Tracks, Speakers, Sessions shows you information from the respective conference. The complete source code for the application and detailed instructions are availaable at glassfish.org/javaone2011. In short: Download the sample app and unzip Download GlassFish build b05. Download platform-specific Load Balancer template Run "bin/install.sh" to configure GlassFish Pick javaone-sf-2011.sql or devoxx-2011.sql for database initialization You can also watch the application in action in this video: A breaking news shared at the conference was that Devoxx France is coming from April 18- 20 and 75% of the talks will be in French. Stay tuned for more details on that. I'm sure Antonio and gang will put up a great show out there! Just a tip for the first timers to Devoxx ... A bus leaves from Brussels airport to Antwerp city center between 4am - 11pm at the top of every hour, takes about 45 minutes, and costs 10 euros (only cash). Take a tram #6 (going towards Luchtbal) from Astrid station (next to the city center) and get off at the last station for Metropolis. It takes about 15 minutes. Purchase a day pass at the station using kiosks (much cheaper) or you can buy in the bus as well (about double the price). Either way, cash only. Here are a few pictures captured from the event: And the complete album here: Thank you Stephan for giving me an opportunity to speak at my first Devoxx. I hope to be back next year, just in time for Java EE 7 going final!

  • A debugging experience with "highly compatible" ASP.NET 4.5

    - by Jeff
    I have to admit that I will pretty much upgrade software for no reason other than being on the latest version. I won't do it if it's super expensive (Adobe gets money from me about once every three or four years at best), but particularly with frameworks and stuff generally available as part of my MSDN subscription, I'll be bleeding edge. CoasterBuzz was running on the MVC 4 framework pretty much as soon as they did a "go live" license for it. I didn't really jump in head-first with Windows 8 and Visual Studio 2012, in part because I just wasn't interested in doing the reinstalls for each new version. Turns out there weren't that many revisions anyway. But when the final versions were released a week and a half ago, I jumped in. I saw on one of the Microsoft sites that .Net 4.5 was a "highly compatible in-place update" to the framework. Good enough for me. I was obviously running it by default in Windows 8, and installed it on my production server. I suppose it's "highly compatible," except when it isn't. Three of my sites are running with various flavors of the MVC version of POP Forums. All of them stopped working under ASP.NET 4.5. It was not immediately obvious what the problem might be beyond an exception indicating that there were no repository classes registered with Ninject, which I use for dependency injection in the forums. This was made all the more weird by the fact that it ran fine locally in the dev Web host. My first instinct was to spin up a Windows Server VM on my local box and put the remote debugger on it. (Side note: running multiple VM's on a Retina MacBook Pro with 16 gigs of RAM is pretty much the most awesome thing ever. I can't believe this computer is for real, and not a 50-pound tower under my desk.) What might have been going on in IIS that doesn't happen in Visual Studio? In the debugging process, I realized that I might be looking in the wrong place. POP Forums creates a Ninject container using a method called from a PreApplicationStartMethod attribute, and at that time registers a module (what Ninject uses to map interfaces to implementations) that maps all of the core dependencies. It also creates an instance of an HttpModule that originally hosted the "services" (search indexing, mailer, etc.), but now just records errors. That's all well and good, but the actual repository mapping, where data is actually read or persisted, happens in Application_Start() in global.asax. The idea there is that you can swap out the SqlSingleWebServer repos for something tuned for multiple servers, Oracle or something else. Of course, if I used something like StructureMap, which does convention-based mapping for dependency injection (a class implementing ISettingsRepository called SettingsRepository is automagically mapped), I wouldn't have to worry about it. In any case, the HttpModule, being instantiated before Application_Start() gets to run, would throw because there was no repo mapped where it could get settings from the database. This makes total sense. The fix is sort of a hack, where I don't setup the innards of the HttpModule until a call to its BeginRequest is made. I say it's a hack, because its primary function, logging exceptions, won't work until the app has warmed up. Still, this brings up an interesting question about the race condition, and what changed in 4.5 when it's running in IIS. In ASP.NET 4, it would appear that the code called via the PreApplicationStartMethod was either failing silently, and running again later, or it was getting to that code after Application_Start was called. In any case, weird thing. The real pain point I'm experiencing now is a bug in MVC 4 that is extremely serious because it renders the mobile/alternate view functionality very much broken.

  • Writing C# Code Using SOLID Principles

    - by bipinjoshi
    Most of the modern programming languages including C# support objected oriented programming. Features such as encapsulation, inheritance, overloading and polymorphism are code level features. Using these features is just one part of the story. Equally important is to apply some object oriented design principles while writing your C# code. SOLID principles is a set of five such principles--namely Single Responsibility Principle, Open/Closed Principle, Liskov Substitution Principle, Interface Segregation Principle and Dependency Inversion Principle. Applying these time proven principles make your code structured, neat and easy to maintain. This article discusses SOLID principles and also illustrates how they can be applied to your C# code.http://www.binaryintellect.net/articles/7f857089-68f5-4d76-a3b7-57b898b6f4a8.aspx

  • Goodby jQuery Templates, Hello JsRender

    - by SGWellens
    A funny thing happened on my way to the jQuery website, I blinked and a feature was dropped: jQuery Templates have been discontinued. The new pretender to the throne is JsRender. jQuery Templates looked pretty useful when they first came out. Several articles were written about them but I stayed away because being on the bleeding edge of technology is not a productive place to be. I wanted to wait until it stabilized…in retrospect, it was a serendipitous decision. This time however, I threw all caution to the wind and took a close look at JSRender. Why? Maybe I'm having a midlife crisis; I'll go motorcycle shopping tomorrow. Caveat, here is a message from the site: Warning: JsRender is not yet Beta, and there may be frequent changes to APIs and features in the coming period. Fair enough, we've been warned. The first thing we need is some data to render. Below is some JSON formatted data. Typically this will come from an asynchronous call to a web service. For simplicity, I hard coded a variable:     var Golfers = [         { ID: "1", "Name": "Bobby Jones", "Birthday": "1902-03-17" },         { ID: "2", "Name": "Sam Snead", "Birthday": "1912-05-27" },         { ID: "3", "Name": "Tiger Woods", "Birthday": "1975-12-30" }         ]; We also need some templates, I created two. Note: The script blocks have the id property set. They are needed so JsRender can locate them.     <script id="GolferTemplate1" type="text/html">         {{=ID}}: <b>{{=Name}}</b> <i>{{=Birthday}}</i> <br />     </script>       <script id="GolferTemplate2" type="text/html">         <tr>             <td>{{=ID}}</td>             <td><b>{{=Name}}</b></td>             <td><i>{{=Birthday}}</i> </td>         </tr>     </script> Including the correct JavaScript files is trivial:     <script src="Scripts/jquery-1.7.js" type="text/javascript"></script>     <script src="Scripts/jsrender.js" type="text/javascript"></script> Of course we need some place to render the output:     <div id="GolferDiv"></div><br />     <table id="GolferTable"></table> The code is also trivial:     function Test()     {         $("#GolferDiv").html($("#GolferTemplate1").render(Golfers));         $("#GolferTable").html($("#GolferTemplate2").render(Golfers));           // you can inspect the rendered html if there are poblems.         // var html = $("#GolferTemplate2").render(Golfers);     } And here's what it looks like with some random CSS formatting that I had laying around.    Not bad, I hope JsRender lasts longer than jQuery Templates. One final warning, a lot of jQuery code is ugly, butt-ugly. If you do look inside the jQuery files, you may want to cover your keyboard with some plastic in case you get vertigo and blow chunks. I hope someone finds this useful. Steve Wellens CodeProject

  • Microsoft Sql Server driver for Nodejs - Part 2

    - by chanderdhall
    Nodejs, Sql server and Json response with Rest This post is part 2 of Microsoft Sql Server driver for Node js.In this post we will look at the JSON responses from the Microsoft Sql Server driver for Node js. Pre-requisites: If you have read the Part 1 of the series, you should be good. We will be using a framework for Rest within Nodejs - Restify, but that would need no prior learning. Restify: Restify is a simple node module for building RESTful services. It is slimmer than Express. Express is a complete module that has all what you need to create a full-blown browser app. However, Restify does not have additional overhead of templating, rendering etc that would be needed if your app has views. So, as the name suggests it's an awesome framework for building RESTful services and is very light-weight. Set up - You can continue with the same directory or project structure we had in the previous post, or can start a new one. Install restify using npm and you are good to go. npm install restify Go to Server.js and include Restify in your solution. Then create the server object using restify.CreateServer() - SLICK - ha? var restify = require('restify'); var server = restify.createServer(); server.listen(8080, function () { console.log('%s listening at %s', server.name, server.url); }); Then make sure you provide a port for the Server to listen at. The call back function is optional but helps you for debugging purposes. Once you are done, save the file and then go to the command prompt and hit 'node server.js' and you should see the following:   To test the server, go to your browser and type the address 'http://localhost:8080/' and oops you will see an error.   Why is that? - Well because we haven't defined any routes. Let's go ahead and create a route. To begin with I'd like to return whatever is typed in the url after my name and the following code should do it. server.get('/ChanderDhall/:status', function respond(req, res, next) { res.end("hello " + req.params.name + "") }); You can also avoid writing call backs inline. Something like this. function respond(req, res, next) { res.end("Chander Dhall " + req.params.name + ""); } server.get('/hello/:name', respond); Now if you go ahead and type http://localhost:8080/ChanderDhall/LovesNode you will get the response 'Chander Dhall loves node'. NOTE: Make sure your url has the right case as it's case-sensitive. You could have also typed it in as 'server.get('/chanderdhall/:name', respond);' Stored procedure: We've talked a lot about Restify now, but keep in mind the post is about being able to use Sql server with Node and return JSON. To see this in action, let's go ahead and create another route to a list of Employees from a stored procedure. server.get('/Employees', Employees); The following code will return a JSON response.  function Employees(req, res, next) { res.header("Content-Type: application/json"); //Need to specify the Content-Type which is //JSON in our case. sql.open(conn_str, function (err, conn) { if (err) { //Logs an error console.log("Error opening the database connection!"); return; } console.log("before query!"); conn.queryRaw("exec sp_GetEmployees", function (err, results) { if (err) { //Connection is open but an error occurs whileWhat else can be done? May be create a formatter or may be even come up with a hypermedia type but that may upset some pragmatists. Well, that's going to be a totally different discussion and is really not part of this series. Summary: We've discussed how to execute a stored procedure using Microsoft Sql Server driver for Node. Also, we have discussed how to format and send out a clean JSON to the app calling this API.

  • ORM Profiler v1.1 has been released!

    - by FransBouma
    We've released ORM Profiler v1.1, which has the following new features: Real time profiling A real time viewer (RTV) has been added, which gives insight in the activity as it is received by the client, in two views: a chronological connection overview and an activity graph overview. This RTV allows the user to directly record to a snapshot using record buttons, pause the view, mark a range to create a snapshot from that range, and view graphs about the # of connection open actions and # of commands per second. The RTV has a 'range' in which it keeps live data and auto-cleans data that's older than this range. Screenshot of the activity graphs part of the real-time viewer: Low-level activity tab A new tab has been added to the Application tabs: the Low-level activity tab. This tab shows the main activity as it has been received over the named pipe. It can help to get insight in the chronological activity without the grouping over connections, so multiple connections at the same time per thread are easier to spot. Clicking a command will sync the rest of the application tabs, clicking a row will show the details below the splitter bar, as it is done with the other application tabs as well. Default application name in interceptor When an empty string or null is passed for application name to the Initialize method of the interceptor, the AppDomain's friendly name is used instead. Copy call stack to clipboard A call stack viewed in a grid in various parts of the UI is now copyable to the clipboard by clicking a button. Enable/Disable interceptor from the config file It's now possible to enable/disable the interceptor Initialization from the application's config file, using: Code: <appSettings> <add key="ORMProfilerEnabled" value="true"/> </appSettings> if value is true, the interceptor's Initialize method will proceed. If the value is false, the interceptor's Initialize method will not proceed and initialization won't be performed, meaning no interception will take place. If the setting is absent, or misconfigured, the Initialize method will proceed as normal and perform the initialization. Stored procedure calls for select databases are now properly displayed as a call For the databases: SQL Server, Oracle, DB2, Sybase ASA, Sybase ASE and Informix a stored procedure call is displayed as an execute/call statement and copy to clipboard works as-is. I'm especially happy with the new real-time profiling feature in ORM Profiler, which is the flagship feature for this release: it offers a completely new way to use the profiler, namely directly during debugging: you can immediately see what's going on without the necessity of a snapshot. The activity graph feature combined with the auto-cleanup of older data, allows you to keep the profiler open for a long period of time and see any spike of activity on the profiled application.

  • @CodeStock 2012 Review: Rob Gillen ( @argodev ) - Anatomy of a Buffer Overflow Attack

    Anatomy of a Buffer Overflow AttackSpeaker: Rob GillenTwitter: @argodevBlog: rob.gillenfamily.net Honestly, this talk was over my head due to my lack of knowledge of low level programming, and I think that most of the other attendees would agree. However I did get the basic concepts that we was trying to get across. Fortunately most high level programming languages handle most of the low level concerns regarding preventing buffer overflow attacks. What I got from this talk was to validate all input data from external sources.

  • Willy Rotstein on Analytics and Social Media in Retail

    - by sarah.taylor(at)oracle.com
    Recently I came across a presentation from Dan Zarrella on "The Science of Retweets. (http://www.slideshare.net/HubSpot/the-science-of-retweets-with-dan-zarrella). It is an insightful, fact-based analysis of how tweets propagate and what makes them successful. The analysis is of course very interesting for those of us interested Tweeting. However, what really caught my attention is how well it illustrates, form a very different angle, some of the issues I am discussing with retailers these days. In particular the opportunities that e-commerce and social media open to those retailers with the appetite and vision to tackle the associated analytical challenges. And these challenges are of course not straightforward.   In his presentation Dan introduces the concept of Observability, I haven't had the opportunity to discuss with Dan his specific definition for the term. However, in practical retail terms, I would say that it means that through social media (and other web channels such as search) we can analyze and track processes by measuring Indicators that were not measurable before. The focus is in identifying patterns across a large number of consumers rather than what a particular individual "Likes".   The potential impact for retailers is huge. It opens the opportunity to monitor changes in consumer preference  and plan the business accordingly. And you can do this almost "real time" rather than through infrequent surveys that provide a "rear view" picture of your consumer behaviour. For instance, you could envision identifying when a particular set of fashion styles are breaking out from the pack, and commit a re-buy. Or you could monitor when the preference for a specific mobile device has declined and hence markdowns should be considered; or how demand for a specific ready-made food typically flows across regions and manage the inventory accordingly. Search, blogging, website and store data may need to be considered in identifying these trends. The data volumes involved are huge (check Andrea Morgan's recent post on "Big Data" in retail) but so are the benefits. As Andrea says, for the first time we can start getting insight into "Why" the business is performing in a certain way rather than just reporting on what is happening. And it is not just about the data volumes. Tackling the challenge also calls for integrated planning systems that can bring data and insight into the context of the Decision Making process Buyers, Merchandisers and Supply Chain managers are following. I strongly believe that only when data and process come together you can move from the anecdotal to systematically improving business performance.   I would love to hear your opinions on these trends and where you think Retail is heading to exploit these topics - please email me: [email protected]

  • Importing data from text file to specific columns using BULK INSERT

    - by Dinesh Asanka
    Bulk insert is much faster than using other techniques such as  SSIS. However, when you are using bulk insert you can’t insert to specific columns. If, for example, there are five columns in a table you should have five values for each record in the text file you are importing from. This is an issue when you are expecting default values to be inserted into tables. Let us say you have table as below: In this table, you are expecting ID, Status and CreatedDate to be updated automatically, so your text file may only have   FirstName  LastName  values as below: Dinesh,Asanka Saman,Liyanage Ruwan,Silva Susantha,Bathige Jude,Peires Sanjeewa,Jayawickrama If you use bulk insert to this table like follows, You will be returned an error: Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 1 (ID). To avoid this you will need to create a view with the columns you are expecting to fill and use bulk insert against it. If you check the table now, you will see table with values in the text file and the default values.
