  • Security Issues with Single Page Apps

    - by Stephen.Walther
    Last week, I was asked to do a code review of a Single Page App built using the ASP.NET Web API, Durandal, and Knockout (good stuff!). In particular, I was asked to investigate whether there any special security issues associated with building a Single Page App which are not present in the case of a traditional server-side ASP.NET application. In this blog entry, I discuss two areas in which you need to exercise extra caution when building a Single Page App. I discuss how Single Page Apps are extra vulnerable to both Cross-Site Scripting (XSS) attacks and Cross-Site Request Forgery (CSRF) attacks. This goal of this blog post is NOT to persuade you to avoid writing Single Page Apps. I’m a big fan of Single Page Apps. Instead, the goal is to ensure that you are fully aware of some of the security issues related to Single Page Apps and ensure that you know how to guard against them. Cross-Site Scripting (XSS) Attacks According to WhiteHat Security, over 65% of public websites are open to XSS attacks. That’s bad. By taking advantage of XSS holes in a website, a hacker can steal your credit cards, passwords, or bank account information. Any website that redisplays untrusted information is open to XSS attacks. Let me give you a simple example. Imagine that you want to display the name of the current user on a page. To do this, you create the following server-side ASP.NET page located at http://MajorBank.com/SomePage.aspx: <%@Page Language="C#" %> <html> <head> <title>Some Page</title> </head> <body> Welcome <%= Request["username"] %> </body> </html> Nothing fancy here. Notice that the page displays the current username by using Request[“username”]. Using Request[“username”] displays the username regardless of whether the username is present in a cookie, a form field, or a query string variable. Unfortunately, by using Request[“username”] to redisplay untrusted information, you have now opened your website to XSS attacks. Here’s how. Imagine that an evil hacker creates the following link on another website (hackers.com): <a href="/SomePage.aspx?username=<script src=Evil.js></script>">Visit MajorBank</a> Notice that the link includes a query string variable named username and the value of the username variable is an HTML <SCRIPT> tag which points to a JavaScript file named Evil.js. When anyone clicks on the link, the <SCRIPT> tag will be injected into SomePage.aspx and the Evil.js script will be loaded and executed. What can a hacker do in the Evil.js script? Anything the hacker wants. For example, the hacker could display a popup dialog on the MajorBank.com site which asks the user to enter their password. The script could then post the password back to hackers.com and now the evil hacker has your secret password. ASP.NET Web Forms and ASP.NET MVC have two automatic safeguards against this type of attack: Request Validation and Automatic HTML Encoding. Protecting Coming In (Request Validation) In a server-side ASP.NET app, you are protected against the XSS attack described above by a feature named Request Validation. If you attempt to submit “potentially dangerous” content — such as a JavaScript <SCRIPT> tag — in a form field or query string variable then you get an exception. Unfortunately, Request Validation only applies to server-side apps. Request Validation does not help in the case of a Single Page App. In particular, the ASP.NET Web API does not pay attention to Request Validation. You can post any content you want – including <SCRIPT> tags – to an ASP.NET Web API action. For example, the following HTML page contains a form. When you submit the form, the form data is submitted to an ASP.NET Web API controller on the server using an Ajax request: <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> </head> <body> <form data-bind="submit:submit"> <div> <label> User Name: <input data-bind="value:user.userName" /> </label> </div> <div> <label> Email: <input data-bind="value:user.email" /> </label> </div> <div> <input type="submit" value="Submit" /> </div> </form> <script src="Scripts/jquery-1.7.1.js"></script> <script src="Scripts/knockout-2.1.0.js"></script> <script> var viewModel = { user: { userName: ko.observable(), email: ko.observable() }, submit: function () { $.post("/api/users", ko.toJS(this.user)); } }; ko.applyBindings(viewModel); </script> </body> </html> The form above is using Knockout to bind the form fields to a view model. When you submit the form, the view model is submitted to an ASP.NET Web API action on the server. Here’s the server-side ASP.NET Web API controller and model class: public class UsersController : ApiController { public HttpResponseMessage Post(UserViewModel user) { var userName = user.UserName; return Request.CreateResponse(HttpStatusCode.OK); } } public class UserViewModel { public string UserName { get; set; } public string Email { get; set; } } If you submit the HTML form, you don’t get an error. The “potentially dangerous” content is passed to the server without any exception being thrown. In the screenshot below, you can see that I was able to post a username form field with the value “<script>alert(‘boo’)</script”. So what this means is that you do not get automatic Request Validation in the case of a Single Page App. You need to be extra careful in a Single Page App about ensuring that you do not display untrusted content because you don’t have the Request Validation safety net which you have in a traditional server-side ASP.NET app. Protecting Going Out (Automatic HTML Encoding) Server-side ASP.NET also protects you from XSS attacks when you render content. By default, all content rendered by the razor view engine is HTML encoded. For example, the following razor view displays the text “<b>Hello!</b>” instead of the text “Hello!” in bold: @{ var message = "<b>Hello!</b>"; } @message   If you don’t want to render content as HTML encoded in razor then you need to take the extra step of using the @Html.Raw() helper. In a Web Form page, if you use <%: %> instead of <%= %> then you get automatic HTML Encoding: <%@ Page Language="C#" %> <% var message = "<b>Hello!</b>"; %> <%: message %> This automatic HTML Encoding will prevent many types of XSS attacks. It prevents <script> tags from being rendered and only allows &lt;script&gt; tags to be rendered which are useless for executing JavaScript. (This automatic HTML encoding does not protect you from all forms of XSS attacks. For example, you can assign the value “javascript:alert(‘evil’)” to the Hyperlink control’s NavigateUrl property and execute the JavaScript). The situation with Knockout is more complicated. If you use the Knockout TEXT binding then you get HTML encoded content. On the other hand, if you use the HTML binding then you do not: <!-- This JavaScript DOES NOT execute --> <div data-bind="text:someProp"></div> <!-- This Javacript DOES execute --> <div data-bind="html:someProp"></div> <script src="Scripts/jquery-1.7.1.js"></script> <script src="Scripts/knockout-2.1.0.js"></script> <script> var viewModel = { someProp : "<script>alert('Evil!')<" + "/script>" }; ko.applyBindings(viewModel); </script>   So, in the page above, the DIV element which uses the TEXT binding is safe from XSS attacks. According to the Knockout documentation: “Since this binding sets your text value using a text node, it’s safe to set any string value without risking HTML or script injection.” Just like server-side HTML encoding, Knockout does not protect you from all types of XSS attacks. For example, there is nothing in Knockout which prevents you from binding JavaScript to a hyperlink like this: <a data-bind="attr:{href:homePageUrl}">Go</a> <script src="Scripts/jquery-1.7.1.min.js"></script> <script src="Scripts/knockout-2.1.0.js"></script> <script> var viewModel = { homePageUrl: "javascript:alert('evil!')" }; ko.applyBindings(viewModel); </script> In the page above, the value “javascript:alert(‘evil’)” is bound to the HREF attribute using Knockout. When you click the link, the JavaScript executes. Cross-Site Request Forgery (CSRF) Attacks Cross-Site Request Forgery (CSRF) attacks rely on the fact that a session cookie does not expire until you close your browser. In particular, if you visit and login to MajorBank.com and then you navigate to Hackers.com then you will still be authenticated against MajorBank.com even after you navigate to Hackers.com. Because MajorBank.com cannot tell whether a request is coming from MajorBank.com or Hackers.com, Hackers.com can submit requests to MajorBank.com pretending to be you. For example, Hackers.com can post an HTML form from Hackers.com to MajorBank.com and change your email address at MajorBank.com. Hackers.com can post a form to MajorBank.com using your authentication cookie. After your email address has been changed, by using a password reset page at MajorBank.com, a hacker can access your bank account. To prevent CSRF attacks, you need some mechanism for detecting whether a request is coming from a page loaded from your website or whether the request is coming from some other website. The recommended way of preventing Cross-Site Request Forgery attacks is to use the “Synchronizer Token Pattern” as described here: https://www.owasp.org/index.php/Cross-Site_Request_Forgery_%28CSRF%29_Prevention_Cheat_Sheet When using the Synchronizer Token Pattern, you include a hidden input field which contains a random token whenever you display an HTML form. When the user opens the form, you add a cookie to the user’s browser with the same random token. When the user posts the form, you verify that the hidden form token and the cookie token match. Preventing Cross-Site Request Forgery Attacks with ASP.NET MVC ASP.NET gives you a helper and an action filter which you can use to thwart Cross-Site Request Forgery attacks. For example, the following razor form for creating a product shows how you use the @Html.AntiForgeryToken() helper: @model MvcApplication2.Models.Product <h2>Create Product</h2> @using (Html.BeginForm()) { @Html.AntiForgeryToken(); <div> @Html.LabelFor( p => p.Name, "Product Name:") @Html.TextBoxFor( p => p.Name) </div> <div> @Html.LabelFor( p => p.Price, "Product Price:") @Html.TextBoxFor( p => p.Price) </div> <input type="submit" /> } The @Html.AntiForgeryToken() helper generates a random token and assigns a serialized version of the same random token to both a cookie and a hidden form field. (Actually, if you dive into the source code, the AntiForgeryToken() does something a little more complex because it takes advantage of a user’s identity when generating the token). Here’s what the hidden form field looks like: <input name=”__RequestVerificationToken” type=”hidden” value=”NqqZGAmlDHh6fPTNR_mti3nYGUDgpIkCiJHnEEL59S7FNToyyeSo7v4AfzF2i67Cv0qTB1TgmZcqiVtgdkW2NnXgEcBc-iBts0x6WAIShtM1″ /> And here’s what the cookie looks like using the Google Chrome developer toolbar: You use the [ValidateAntiForgeryToken] action filter on the controller action which is the recipient of the form post to validate that the token in the hidden form field matches the token in the cookie. If the tokens don’t match then validation fails and you can’t post the form: public ActionResult Create() { return View(); } [ValidateAntiForgeryToken] [HttpPost] public ActionResult Create(Product productToCreate) { if (ModelState.IsValid) { // save product to db return RedirectToAction("Index"); } return View(); } How does this all work? Let’s imagine that a hacker has copied the Create Product page from MajorBank.com to Hackers.com – the hacker grabs the HTML source and places it at Hackers.com. Now, imagine that the hacker trick you into submitting the Create Product form from Hackers.com to MajorBank.com. You’ll get the following exception: The Cross-Site Request Forgery attack is blocked because the anti-forgery token included in the Create Product form at Hackers.com won’t match the anti-forgery token stored in the cookie in your browser. The tokens were generated at different times for different users so the attack fails. Preventing Cross-Site Request Forgery Attacks with a Single Page App In a Single Page App, you can’t prevent Cross-Site Request Forgery attacks using the same method as a server-side ASP.NET MVC app. In a Single Page App, HTML forms are not generated on the server. Instead, in a Single Page App, forms are loaded dynamically in the browser. Phil Haack has a blog post on this topic where he discusses passing the anti-forgery token in an Ajax header instead of a hidden form field. He also describes how you can create a custom anti-forgery token attribute to compare the token in the Ajax header and the token in the cookie. See: http://haacked.com/archive/2011/10/10/preventing-csrf-with-ajax.aspx Also, take a look at Johan’s update to Phil Haack’s original post: http://johan.driessen.se/posts/Updated-Anti-XSRF-Validation-for-ASP.NET-MVC-4-RC (Other server frameworks such as Rails and Django do something similar. For example, Rails uses an X-CSRF-Token to prevent CSRF attacks which you generate on the server – see http://excid3.com/blog/rails-tip-2-include-csrf-token-with-every-ajax-request/#.UTFtgDDkvL8 ). For example, if you are creating a Durandal app, then you can use the following razor view for your one and only server-side page: @{ Layout = null; } <!DOCTYPE html> <html> <head> <title>Index</title> </head> <body> @Html.AntiForgeryToken() <div id="applicationHost"> Loading app.... </div> @Scripts.Render("~/scripts/vendor") <script type="text/javascript" src="~/App/durandal/amd/require.js" data-main="/App/main"></script> </body> </html> Notice that this page includes a call to @Html.AntiForgeryToken() to generate the anti-forgery token. Then, whenever you make an Ajax request in the Durandal app, you can retrieve the anti-forgery token from the razor view and pass the token as a header: var csrfToken = $("input[name='__RequestVerificationToken']").val(); $.ajax({ headers: { __RequestVerificationToken: csrfToken }, type: "POST", dataType: "json", contentType: 'application/json; charset=utf-8', url: "/api/products", data: JSON.stringify({ name: "Milk", price: 2.33 }), statusCode: { 200: function () { alert("Success!"); } } }); Use the following code to create an action filter which you can use to match the header and cookie tokens: using System.Linq; using System.Net.Http; using System.Web.Helpers; using System.Web.Http.Controllers; namespace MvcApplication2.Infrastructure { public class ValidateAjaxAntiForgeryToken : System.Web.Http.AuthorizeAttribute { protected override bool IsAuthorized(HttpActionContext actionContext) { var headerToken = actionContext .Request .Headers .GetValues("__RequestVerificationToken") .FirstOrDefault(); ; var cookieToken = actionContext .Request .Headers .GetCookies() .Select(c => c[AntiForgeryConfig.CookieName]) .FirstOrDefault(); // check for missing cookie or header if (cookieToken == null || headerToken == null) { return false; } // ensure that the cookie matches the header try { AntiForgery.Validate(cookieToken.Value, headerToken); } catch { return false; } return base.IsAuthorized(actionContext); } } } Notice that the action filter derives from the base AuthorizeAttribute. The ValidateAjaxAntiForgeryToken only works when the user is authenticated and it will not work for anonymous requests. Add the action filter to your ASP.NET Web API controller actions like this: [ValidateAjaxAntiForgeryToken] public HttpResponseMessage PostProduct(Product productToCreate) { // add product to db return Request.CreateResponse(HttpStatusCode.OK); } After you complete these steps, it won’t be possible for a hacker to pretend to be you at Hackers.com and submit a form to MajorBank.com. The header token used in the Ajax request won’t travel to Hackers.com. This approach works, but I am not entirely happy with it. The one thing that I don’t like about this approach is that it creates a hard dependency on using razor. Your single page in your Single Page App must be generated from a server-side razor view. A better solution would be to generate the anti-forgery token in JavaScript. Unfortunately, until all browsers support a way to generate cryptographically strong random numbers – for example, by supporting the window.crypto.getRandomValues() method — there is no good way to generate anti-forgery tokens in JavaScript. So, at least right now, the best solution for generating the tokens is the server-side solution with the (regrettable) dependency on razor. Conclusion The goal of this blog entry was to explore some ways in which you need to handle security differently in the case of a Single Page App than in the case of a traditional server app. In particular, I focused on how to prevent Cross-Site Scripting and Cross-Site Request Forgery attacks in the case of a Single Page App. I want to emphasize that I am not suggesting that Single Page Apps are inherently less secure than server-side apps. Whatever type of web application you build – regardless of whether it is a Single Page App, an ASP.NET MVC app, an ASP.NET Web Forms app, or a Rails app – you must constantly guard against security vulnerabilities.

  • Windows 8 Will be Here Tomorrow; but Should Silverlight be Gone Today?

    - by andrewbrust
    The software industry lives within an interesting paradox. IT in the enterprise moves slowly and cautiously, upgrading only when safe and necessary.  IT interests intentionally live in the past.  On the other hand, developers, and Independent Software Vendors (ISVs) not only want to use the latest and greatest technologies, but this constituency prides itself on gauging tech’s future, and basing its present-day strategy upon it.  Normally, we as an industry manage this paradox with a shrug of the shoulder and musings along the lines of “it takes all kinds.”  Different subcultures have different tendencies.  So be it. Microsoft, with its Windows operating system (OS), can’t take such a laissez-faire view of the world though.  Redmond relies on IT to deploy Windows and (at the very least) influence its procurement, but it also relies on developers to build software for Windows, especially software that has a dependency on features in new versions of the OS.  It must indulge and nourish developers’ fetish for an early birthing of the next generation of software, even as it acknowledges the IT reality that the next wave will arrive on-schedule in Redmond and will travel very slowly to end users. With the move to Windows 8, and the corresponding shift in application development models, this paradox is certainly in place. On the one hand, the next version of Windows is widely expected sometime in 2012, and its full-scale deployment will likely push into 2014 or even later.  Meanwhile, there’s a technology that runs on today’s Windows 7, will continue to run in the desktop mode of Windows 8 (the next version’s codename), and provides absolutely the best architectural bridge to the Windows 8 Metro-style application development stack.  That technology is Silverlight.  And given what we now know about Windows 8, one might think, as I do, that Microsoft ecosystem developers should be flocking to it. But because developers are trying to get a jump on the future, and since many of them believe the impending v5.0 release of Silverlight will be the technology’s last, not everyone is flocking to it; in fact some are fleeing from it.  Is this sensible?  Is it not unprecedented?  What options does it lead to?  What’s the right way to think about the situation? Is v5.0 really the last major version of the technology called Silverlight?  We don’t know.  But Scott Guthrie, the “father” and champion of the technology, left the Developer Division of Microsoft months ago to work on the Windows Azure team, and he took his people with him.  John Papa, who was a very influential Redmond-based evangelist for Silverlight (and is a Visual Studio Magazine author), left Microsoft completely.  About a year ago, when initial suspicion of Silverlight’s demise reached significant magnitude, Papa interviewed Guthrie on video and their discussion served to dispel developers’ fears; but now they’ve moved on. So read into that what you will and let’s suppose, for the sake of argument, speculation that Silverlight’s days of major revision and iteration are over now is correct.  Let’s assume the shine and glimmer has dimmed.  Let’s assume that any Silverlight application written today, and that therefore any investment of financial and human resources made in Silverlight development today, is destined for rework and extra investment in a few years, if the application’s platform needs to stay current. Is this really so different from any technology investment we make?  Every framework, language, runtime and operating system is subject to change, to improvement, to flux and, yes, to obsolescence.  What differs from project to project, is how near-term that obsolescence is and how disruptive the change will be.  The shift from .NET 1.1. to 2.0 was incremental.  Some of the further changes were too.  But the switch from Windows Forms to WPF was major, and the change from ASP.NET Web Services (asmx) to Windows Communication Foundation (WCF) was downright fundamental. Meanwhile, the transition to the .NET development model for Windows 8 Metro-style applications is actually quite gentle.  The finer points of this subject are covered nicely in Magenic’s excellent white paper “Assessing the Windows 8 Development Platform.” As the authors of that paper (including Rocky Lhotka)  point out, Silverlight code won’t just “port” to Windows 8.  And, no, Silverlight user interfaces won’t either; Metro always supports XAML, but that relationship is not commutative.  But the concepts, the syntax, the architecture and developers’ skills map from Silverlight to Windows 8 Metro and the Windows Runtime (WinRT) very nicely.  That’s not a coincidence.  It’s not an accident.  This is a protected transition.  It’s not a slap in the face. There are few things that are unnerving about this transition, which make it seem markedly different from others: The assumed end of the road for Silverlight is something many think they can see.  Instead of being ignorant of the technology’s expiration date, we believe we know it.  If ignorance is bliss, it would seem our situation lacks it. The new technology involving WinRT and Metro involves a name change from Silverlight. .NET, which underlies both Silverlight and the XAML approach to WinRT development, has just about reached 10 years of age.  That’s equivalent to 80 in human years, or so many fear. My take is that the combination of these three factors has contributed to what for many is a psychologically compelling case that Silverlight should be abandoned today and HTML 5 (the agnostic kind, not the Windows RT variety) should be embraced in its stead.  I understand the logic behind that.  I appreciate the preemptive, proactive, vigilant conscientiousness involved in its calculus.  But for a great many scenarios, I don’t agree with it.  HTML 5 clients, no matter how impressive their interactivity and the emulation of native application interfaces they present may be, are still second-class clients.  They are getting better, especially when hardware acceleration and fast processors are involved.  But they still lag.  They still feel like they’re emulating something, like they’re prototypes, like they’re not comfortable in their own skins.  They are based on compromise, and they feel compromised too. HTML 5/JavaScript development tools are getting better, and will get better still, but they are not as productive as tools for other environments, like Flash, like Silverlight or even more primitive tooling for iOS or Android.  HTML’s roots as a document markup language, rather than an application interface, create a disconnect that impedes productivity.  I do not necessarily think that problem is insurmountable, but it’s here today. If you’re building line-of-business applications, you need a first-class client and you need productivity.  Lack of productivity increases your costs and worsens your backlog.  A second class client will erode user satisfaction, which is never good.  Worse yet, this erosion will be inconspicuous, rather than easily identified and diagnosed, because the inferiority of an HTML 5 client over a native one is hard to identify and, notably, doing so at this juncture in the industry is unpopular.  Why would you fault a technology that everyone believes is revolutionary?  Instead, user disenchantment will remain latent and yet will add to the malaise caused by slower development. If you’re an ISV and you’re coveting the reach of running multi-platform, it’s a different story.  You’ve likely wanted to move to HTML 5 already, and the uncertainty around Silverlight may be the only remaining momentum or pretext you need to make the shift.  You’re deploying many more copies of your application than a line-of-business developer is anyway; this makes the economic hit from lower productivity less impactful, and the wider potential installed base might even make it profitable. But no matter who you are, it’s important to take stock of the situation and do it accurately.  Continued, but merely incremental changes in a development model lead to conservatism and general lack of innovation in the underlying platform.  Periods of stability and equilibrium are necessary, but permanence in that equilibrium leads to loss of platform relevance, market share and utility.  Arguably, that’s already happened to Windows.  The change Windows 8 brings is necessary and overdue.  The marked changes in using .NET if we’re to build applications for the new OS are inevitable.  We will ultimately benefit from the change, and what we can reasonably hope for in the interim is a migration path for our code and skills that is navigable, logical and conceptually comfortable. That path takes us to a place called WinRT, rather than a place called Silverlight.  But considering everything that is changing for the good, the number of disruptive changes is impressively minimal.  The name may be changing, and there may even be some significance to that in terms of Microsoft’s internal management of products and technologies.  But as the consumer, you should care about the ingredients, not the name.  Turkish coffee and Greek coffee are much the same. Although you’ll find plenty of interested parties who will find the names significant, drinkers of the beverage should enjoy either one.  It’s all coffee, it’s all sweet, and you can tell your fortune from the grounds that are left at the end.  Back on the software side, it’s all XAML, and C# or VB .NET, and you can make your fortune from the product that comes out at the end.  Coffee drinkers wouldn’t switch to tea.  Why should XAML developers switch to HTML?

  • JCP.Next - Early Adopters of JCP 2.8

    - by Heather VanCura
    JCP.Next is a series of three JSRs (JSR 348, JSR 355 and JSR 358), to be defined through the JCP process itself, with the JCP Executive Committee serving as the Expert Group. The proposed JSRs will modify the JCP's processes  - the Process Document and Java Specification Participation Agreement (JSPA) and will apply to all new JSRs for all Java platforms.   The first - JCP.next.1, or more formally JSR 348, Towards a new version of the Java Community Process - was completed and put into effect in October 2011 as JCP 2.8. This focused on a small number of simple but important changes to make our process more transparent and to enable broader participation. We're already seeing the benefits of these changes as new and existing JSRs adopt the new requirements. The second - JSR 355, Executive Committee Merge, is also Final. You can read the JCP 2.9 Process Document .  As part of the JSR 355 Final Release, the JCP Executive Committee published revisions to the JCP Process Document (version 2.9) and the EC Standing Rules (version 2.2).  The changes went into effect following the 2012 EC Elections in November. The third JSR 358, A major revision of the Java Community Process was submitted in June 2012.  This JSR will modify the Java Specification Participation Agreement (JSPA) as well as the Process Document, and will tackle a large number of complex issues, many of them postponed from JSR 348. For these reasons, the JCP EC (acting as the Expert Group for this JSR), expects to spend a considerable amount of time working on. The JSPA is defined by the JCP as "a one-year, renewable agreement between the Member and Oracle. The success of the Java community depends upon an open and transparent JCP program.  JSR 358, A major revision of the Java Community Process, is now in process and can be followed on java.net. The following JSRs and Spec Leads were the early adopters of JCP 2.8, who voluntarily migrated their JSRs from JCP 2.x to JCP 2.8 or above.  More candidates for 2012 JCP Star Spec Leads! JSR 236, Concurrency Utilities for Java EE (Anthony Lai/Oracle), migrated April 2012 JSR 308, Annotations on Java Types (Michael Ernst, Alex Buckley/Oracle), migrated September 2012 JSR 335, Lambda Expressions for the Java Programming Language (Brian Goetz/Oracle), migrated October 2012 JSR 337, Java SE 8 Release Contents (Mark Reinhold/Oracle) – EG Formation, migrated September 2012 JSR 338, Java Persistence 2.1 (Linda DeMichiel/Oracle), migrated January 2012 JSR 339, JAX-RS 2.0: The Java API for RESTful Web Services (Santiago Pericas-Geertsen, Marek Potociar/Oracle), migrated July 2012 JSR 340, Java Servlet 3.1 Specification (Shing Wai Chan, Rajiv Mordani/Oracle), migrated August 2012 JSR 341, Expression Language 3.0 (Kin-man Chung/Oracle), migrated August 2012 JSR 343, Java Message Service 2.0 (Nigel Deakin/Oracle), migrated March 2012 JSR 344, JavaServer Faces 2.2 (Ed Burns/Oracle), migrated September 2012 JSR 345, Enterprise JavaBeans 3.2 (Marina Vatkina/Oracle), migrated February 2012 JSR 346, Contexts and Dependency Injection for Java EE 1.1 (Pete Muir/RedHat) – migrated December 2011

  • Difference between Website and Web Application in ASP.NET

    - by SAMIR BHOGAYTA
    Web site in Visual Studio 2005: A web site is just a group of all files in a folder and sub folders. There is no project file. All files under the specific folder - including your word documents, text files, images etc are part of the web site. You have to deploy all files including source files (unless you pre compile them) to the server. Files are compiled dynamically during run time. To create a "web site", you need to use the menu File New Website You will have the option to choose either one of the following location types: # File System - Allows you to choose a folder to put all the files. # Http - Allows you to choose a virtual directory to put the files. # FTP - Allows you to choose an ftp location. In any of the above cases, no project file is created automatically. Visual Studio considers all files under the folder are part of the web site. There will be no single assembly created and you will nto see a "Bin" folder. The benefits of this model is, you do not need a project file or virtual directory to open a project. It is very handy when you share or download code from the internet. You just need to copy the downloaded code into a folder and you are ready to go! Web Application Project in Visual Studio 2005: Microsoft introduced the "web site" concept where all files under a web site are part of the site, hoping that the development community is going to love that. In fact, this is very usefull to share code. However, they did not consider millions of existing web applications where people are comfortable with the "project" based application. Also, there were lot of web applications where several un wanted files were kept under the web site folder. So, the new model did not work well for them. When people started screaming, Microsoft came up with the answer. On April 7, 2006, they announced "Visual Studio 2005 Web Application Projects" as an Add-On to Visual Studio 2005. This Add-On will allow you to create and use web applications just like the way it used to be in Visual Studio 2003. The Visual Studio 2005 Web Application Project model uses the same project, build and compilation method as the Visual Studio .NET 2003 web project model. All code files within the project are compiled into a single assembly that is built and copied in the Bin directory. All files contained within the project are defined within a project file (as well as the assembly references and other project meta-data settings). Files under the web's file-system root that are not defined in the project file are not considered part of the web project.

  • The Work Order Printing Challenge

    - by celine.beck
    One of the biggest concerns we've heard from maintenance practitioners is the ability to print and batch print work order details along with its accompanying attachments. Indeed, maintenance workers traditionally rely on work order packets to complete their job. A standard work order packet can include a variety of information like equipment documentation, operating instructions, checklists, end-of-task feedback forms and the likes. Now, the problem is that most Asset Lifecycle Management applications do not provide a simple and efficient solution for process printing with document attachments. Work order forms can be easily printed but attachments are usually left out of the printing process. This sounds like a minor problem, but when you are processing high volume of work orders on a regular basis, this inconvenience can result in important inefficiencies. In order to print work order and its related attachments, maintenance personnel need to print the work order details and then go back to the work order and open each individual attachment using the proper authoring application to view and print each document. The printed output is collated into a work order packet. The AutoVue Document Print Service products that were just released in April 2010 aim at helping organizations address the work order printing challenge. Customers and partners can leverage the AutoVue Document Print Services to build a complete printing solution that complements their existing print server solution with AutoVue's document- and platform-agnostic document print services. The idea is to leverage AutoVue's printing services to invoke printing either programmatically or manually directly from within the work order management application, and efficiently process the printing of complete work order packets, including all types of attachments, from office files to more advanced engineering documents like 2D CAD drawings. Oracle partners like MIPRO Consulting, specialists in PeopleSoft implementations, have already expressed interest in the AutoVue Document Print Service products for their ability to offer print services to the PeopleSoft ALM suite, so that customers are able to print packages of documents for maintenance personnel. For more information on the subject, please consult MIPRO Consulting's article entitled Unsung Value: Primavera and AutoVue Integration into PeopleSoft posted on their blog. The blog post entitled Introducing AutoVue Document Print Service provides additional information on how the solution works. We would also love to hear what your thoughts are on the topic, so please do not hesitate to post your comments/feedback on our blog.

  • CodeStock 2012 Review: Michael Eaton( @mjeaton ) - 3 Simple Things for Increased Productivity

    3 Simple Things for Increased ProductivitySpeaker: Michael EatonTwitter: @mjeatonBlog: http://mjeaton.net/blog This was the first time I had seen Michael Eaton speak but have hear a lot of really good things about his speaking abilities. Needless to say I was really looking forward to his session. He basically addressed the topic of distractions and how they can decrease or increase your productivity as a developer. He makes the case that in order to become more productive you must block/limit all distractions. For example, he covered his top distractions as a developer. Top Distractions Social Media(Twitter, Reddit, Facebook) Wiki sites Phone Email Video Games Coworkers, Friends, Family Michael stated that he uses various types of music to help him block out these distractions in order for him to get into his coding zone. While he states that music works for him, he also notes that he knows of others that cannot really work with music. I have to say I am in the latter group because I require a quiet environment in order to work. A few session attendees also recommended listening to really loud white noise or music in another language other than your own. This allows for less focus to be placed on words being sung compared to the rhythmic beats being played. I have to say that I have not tried these suggestions yet but will in the near future. However, distractions can be very beneficial to productivity in that they give your mind a chance to relax and not think about the issues at hand. He spoke highly of taking vacations, and setting boundaries at work so that develops prevent the problem of burnout. One way he suggested that developer’s combat distractions is to use the Pomodoro technique. In his example he selects one task to do for 20 minutes and he can only do that task during that time. He ignores all other distractions until this task or time limit is complete. After it is completed he allows himself to relax and distract himself for another 5- 10 minutes before his next Pomodoro. This allows him to stay completely focused on a task and when the time is up he can then focus on other things.

  • The Jack LaLanne School of Sysadmins

    - by rickramsey
    Two of my childhood heroes were Tarzan and Jack LaLanne. Tarzan was an obvious choice: what boy wouldn't want to spend his days bungee jumping through the jungle with his own pack of gorillas? Jack Lalanne had a disturbing habit of wearing stretch pants, but he was so damn fit for an old guy that you couldn't help but be impressed. Especially back then, when nobody knew what a dumb bell was, much less Cross-Fit. Here's what he did to celebrate his 70th birthday. Sooner or later we all face a choice in our careers: surrender to the life of a has-been like Bruce Sprinsteen's baseball player or become an unstoppable sysadmin like Jack Lalanne. If you'd rather keep on fighting like Jack, give these resources a look. Brian Bream's blog provides specific suggestions for keeping your skills up to date. The video interviews describe the types of technologies that are challenging what you used to know. Blog: The Old School Sysadmin - A Dying Breed? by Brian Bream "The sysadmin role has been far too dependent on performing repetitive tasks and working in a reactionary mode ... the sysadmin must grow a much larger skill set to be successful. Don’t grow vertically in one technology, grow horizontally amongst many technologies." Just one of the suggestions Brian Bream provides in this excellent blog post. Video: Freeing the Sysadmin From Repetitive Tasks Interview with Marshall Choy Marshall Choy, Director of Optimized Solutions at Oracle was once a sysadmin. And a Solaris engineer. He explains what optimized solutions are, how they are developed and tested, how they handle patching, and how these vertically integrated systems impact the job and duties of a sysadmin. Video: The Oracle Database Appliance Interview with Bob Thome Bob Thome, Senior Director of Product Management, explains what makes the Database Appliance simple, reliable, and affordable, and how it could change the economies and processes of the data center. Video: Why Pinellas County Chose Oracle Exalytics Interview with Gautham Gautham (pronounced like Batman's Gotham) recently led an effort to refresh the Pinellas County hardware systems. He'll explain what they were looking for, why they chose Oracle Exalytics, how they became convinced it was the right decision, and how it changed the way they managed their data center. Video: DTrace for System Administrators Interview with Brendan Gregg This video interview will give you an idea of some of the value-add tasks you can perform when you are freed from the reactive mode that Brian Bream describes in his blog.

  • Oracle and Eloqua Welcome Compendium’s Content Marketing

    - by Mike Stiles
    Yesterday, Oracle announced its acquisition of Compendium, a cloud-based content marketing provider that helps companies plan, produce and deliver engaging content across multiple channels throughout their customers' lifecycle. Why? Because every part of the above paragraph speaks to where modern marketing is and where it’s headed. Customers have now been empowered, thanks to the Internet and particularly social, with access to almost limitless amounts of information about companies and products. This includes the especially influential voices of friends and objective acquaintances that have experience with the product or brand. With mobile, this info is available instantly in the palm of their hand. All of this research and influence mind you, is taking place long before a prospect will ever engage with the brand itself or one of its sales reps. So how does a brand effectively insert itself into these conversations and this flow of the customer journey? Now, more than ever, marketers must deliver relevant and engaging content across multiple channels and throughout the entire customer journey to be useful, helpful, and influential. Compendium has a data-driven content marketing platform that lines up relevant content with customer data and personas so brands can accelerate the conversion of prospects. Now think about combining that with the Oracle Eloqua Marketing Cloud, part of Oracle's comprehensive CX solution. Marketers will be able to automate content delivery across channels by aligning persona-based content with customers' digital body language. Better customer engagement, improved sales lead quality, better return on marketing investment, and higher customer loyalty. Now we’re talking. Does data-driven content marketing have an impact? Compendium customer CVENT is a SaaS company specializing in meetings management tech. They wanted to increase leads & ad performance on their blog and dramatically increase their content. They also wanted to manage the creation, workflow, promotion and distribution of that content. With Compendium, CVENT created over 9,000 content elements, and sales-ready leads grew 325%. So Oracle Eloqua helps you target audiences, know buyers, and automate multi-channel marketing campaigns. Compendium lets you plan, publish, manage and measure content across content types and channels. Now kick it up yet another notch with Oracle’s Analytics, Big Data and Social solutions, and you’re using your marketing dollars to reach the right people in the right place at the right time with the right content. And as if that weren’t enough, your customers will love you for it. @mikestiles

  • Generate DROP statements for all extended properties

    - by jamiet
    This evening I have been attempting to migrate an existing on-premise database to SQL Azure using the wizard that is built-in to SQL Server Management Studio (SSMS). When I did so I received the following error: The following objects are not supported = [MS_Description] = Extended Property Evidently databases containing extended properties can not be migrated using this particular wizard so I set about removing all of the extended properties – unfortunately there were over a thousand of them so I needed a better way than simply deleting each and every one of them manually. I found a couple of resources online that went some way toward this: Drop all extended properties in a MSSQL database by Angelo Hongens Modifying and deleting extended properties by Adam Aspin Unfortunately neither provided a script that exactly suited my needs. Angelo’s covered extended properties on tables and columns however I had other objects that had extended properties on them. Adam’s looked more complete but when I ran it I got an error: Msg 468, Level 16, State 9, Line 78 Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation. So, both great resources but I wasn’t able to use either on their own to get rid of all of my extended properties. Hence, I combined the excellent work that Angelo and Adam had provided in order to manufacture my own script which did successfully manage to generate calls to sp_dropextendedproperty for all of my extended properties. If you think you might be able to make use of such a script then feel free to download it from https://skydrive.live.com/redir.aspx?cid=550f681dad532637&resid=550F681DAD532637!16707&parid=550F681DAD532637!16706&authkey=!APxPIQCatzC7BQ8. This script will remove extended properties on tables, columns, check constraints, default constraints, views, sprocs, foreign keys, primary keys, table triggers, UDF parameters, sproc parameters, databases, schemas, database files and filegroups. If you have any object types with extended properties on them that are not in that list then consult Adam’s aforementioned article – it should prove very useful. I repeat here the message that I have placed at the top of the script: /* This script will generate calls to sp_dropextendedproperty for every extended property that exists in your database. Actually, a caveat: I don't promise that it will catch each and every extended property that exists, but I'm confident it will catch most of them! It is based on this: http://blog.hongens.nl/2010/02/25/drop-all-extended-properties-in-a-mssql-database/ by Angelo Hongens. Also had lots of help from this: http://www.sqlservercentral.com/articles/Metadata/72609/ by Adam Aspin Adam actually provides a script at that link to do something very similar but when I ran it I got an error: Msg 468, Level 16, State 9, Line 78 Cannot resolve the collation conflict between "Latin1_General_100_CS_AS" and "Latin1_General_CI_AS" in the equal to operation. So I put together this version instead. Use at your own risk. Jamie Thomson 2012-03-25 */ Hope this is useful to someone! @Jamiet

  • Fluid VS Responsive Website Development Questions

    - by Aditya P
    As I understand these form the basis for targeting a wide array of devices based on the browser size, given it would be a time consuming to generate different layouts targeting different/specific devices and their resolutions. Questions: Firstly right to the jargon, is there any actual difference between the two or do they mean the same? Is it safe to classify the current development mainly a html5/css3 based one? What popular frameworks are available to easily implement this? What testing methods used in this regard? What are the most common compatibility issues in terms of different browser types? I understand there are methods like this http://css-tricks.com/resolution-specific-stylesheets/ which does this come under?. Are there any external browser detection methods besides the API calls specific to the browser that are employed in this regard? Points of interest [Prior Research before asking these questions] Why shouldn't "responsive" web design be a consideration? Responsive Web Design Tips, Best Practices and Dynamic Image Scaling Techniques A recent list of tutorials 30 Responsive Web Design and Development Tutorials by Eric Shafer on May 14, 2012 Update Ive been reading that the basic point of designing content for different layouts to facilitate a responsive web design is to present the most relevant information. now obviously between the smallest screen width and the highest we are missing out on design elements. I gather from here http://flashsolver.com/2012/03/24/5-top-commercial-responsive-web-designs/ The top of the line design layouts (widths) are desktop layout (980px) tablet layout (768px) smartphone layout – landscape (480px) smartphone layout – portrait (320px) Also we have a popular responsive website testing site http://resizemybrowser.com/ which lists different screen resolutions. I've also come across this while trying to find out the optimal highest layout size to account for http://stackoverflow.com/questions/10538599/default-web-page-width-1024px-or-980px which brings to light seemingly that 1366x768 is a popular web resolution. Is it safe to assume that just accounting for proper scaling from width 980px onwards to the maximum size would be sufficient to accommodate this? given we aren't presenting any new information for the new size. Does it make sense to have additional information ( which conflicts with purpose of responsive web design) to utilize the top size and beyond?

  • Introducing the New Face of Fusion Applications

    - by mvaughan
    By Misha Vaughan and Kathy Miedema, Oracle Applications User Experience At OpenWorld 2012, the Oracle Applications User Experience (UX) team unveiled the new face of Fusion Applications. You may have seen it in sessions presented by Chris Leone, Anthony Lye, Jeremy Ashley or others, or you may have gotten a look on the demogrounds. This screenshot shows the new Oracle Fusion Applications entry experience.Why are we delivering a new face for Fusion Applications? Because, says Ashley, the vice president of the Oracle Applications User Experience team, we want to provide a simple, modern, productive way for users to complete their top quick-entry tasks. The idea is to provide a clear, productive user experience that is backed by the full functionality of Fusion Applications. The first release of the new face of Fusion focuses on three types of users. It provides a fully functional gateway to Fusion Applications for: New and casual users who need quick access to self-service tasks Professional users who need fast access to quick-entry, high-volume tasks Users who are looking for a way to quickly brand their portal for employees The new face of Fusion allows users to move easily from navigation to action, Ashley said, and it has been designed for any device -- Mac, PC, iPad, Android, SmartBoard -- in the browser. The Oracle Fusion Applications Employee Directory. How did we build it? The new face of Fusion essentially is a custom shell, developed by the Apps UX team, and a set of page templates that embodies a simple design aesthetic. It’s repeatable, providing consistency across its pages, and requires little to zero training. More specifically, the new face of Fusion has been built on ADF. The Applications UX team created pages in JDeveloper using local tasks flows bound to existing view objects. Three new components were commissioned from ADF, and existing Fusion components were re-skinned to deliver a simple, modern user experience. It really is that simple – and to prove that point, we’ve been sharing our story around the new face of Fusion on several Oracle channels such as this one. Want to know more? Check the VoX blog for our favorite highlights from OpenWorld, which included demos of the new face of Fusion. And take a look at these posts from Ace Directors Debra Lilley, and Floyd Teter. Special mention to Floyd for the first screen shot credit. Also a nod to Wilfred vander Deijl for capturing the demo to share as part 1 and part 2. We will also be hitting upcoming user group conferences with our demos, and you can always reach out to one of our Fusion User Experience Advocates for a look.

  • ASP.NET ViewState Tips and Tricks #2

    - by João Angelo
    If you need to store complex types in ViewState DO implement IStateManager to control view state persistence and reduce its size. By default a serializable object will be fully stored in view state using BinaryFormatter. A quick comparison for a complex type with two integers and one string property produces the following results measured using ASP.NET tracing: BinaryFormatter: 328 bytes in view state IStateManager: 28 bytes in view state BinaryFormatter sample code: // DO NOT [Serializable] public class Info { public int Id { get; set; } public string Name { get; set; } public int Age { get; set; } } public class ExampleControl : WebControl { protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (!this.Page.IsPostBack) { this.User = new Info { Id = 1, Name = "John Doe", Age = 27 }; } } public Info User { get { object o = this.ViewState["Example_User"]; if (o == null) return null; return (Info)o; } set { this.ViewState["Example_User"] = value; } } } IStateManager sample code: // DO public class Info : IStateManager { public int Id { get; set; } public string Name { get; set; } public int Age { get; set; } private bool isTrackingViewState; bool IStateManager.IsTrackingViewState { get { return this.isTrackingViewState; } } void IStateManager.LoadViewState(object state) { var triplet = (Triplet)state; this.Id = (int)triplet.First; this.Name = (string)triplet.Second; this.Age = (int)triplet.Third; } object IStateManager.SaveViewState() { return new Triplet(this.Id, this.Name, this.Age); } void IStateManager.TrackViewState() { this.isTrackingViewState = true; } } public class ExampleControl : WebControl { protected override void OnLoad(EventArgs e) { base.OnLoad(e); if (!this.Page.IsPostBack) { this.User = new Info { Id = 1, Name = "John Doe", Age = 27 }; } } public Info User { get; set; } protected override object SaveViewState() { return new Pair( ((IStateManager)this.User).SaveViewState(), base.SaveViewState()); } protected override void LoadViewState(object savedState) { if (savedState != null) { var pair = (Pair)savedState; this.User = new Info(); ((IStateManager)this.User).LoadViewState(pair.First); base.LoadViewState(pair.Second); } } }

  • Just another web startup - platform comparison

    - by Holland
    I'm looking to do a web startup which involves something along the lines of an ecommerce site, yet a little more in depth than that. While it's something that I would rather not go into detail with in terms of the initial idea, I can specify (on a basic level) what would be required of the website. If you have any observations or opinions derived from personal experience, which relate to what you see here, I'd appreciate it if you could share these. Paypal's API interaction (definitely). From what I've read about their API, integration with it into their website is VERY expensive, so I'd probably hold off on that until I've (hopefully) generated money and write my own simple credit-card interaction system. SQL Backend (obviously) PostgreSQL seems like a pretty good choice, as from what I've read, it's structure is a bit more "object-oriented" than, say, MySQL. Then again, I've used MySQL before and haven't had much problem with it whatsoever. Would it be worth learning PostgreSQL for this purpose? Java or .Net implementation (Preferably Mono, so I can use .Net while hosting the website using Apache). The reason for this is because, frankly, while I know PHP is a great platform to develop websites with, I hate developing with it. Before someone chimes in and flames me for saying that, note that I have nothing against the language, I just don't like it for my purposes. While Mono may be good to go with, I'm aware that ASP.Net MVC 3 hasn't been released for Mono yet, which may be a pain to work with, without their Razor syntax. Ontop of that, it seems Java is completely FULL of class libraries which deal with web development, that can be downloaded from the web. If anyone has any experience with these, I'd appreciate if that were posted. From what I've read about Spring and Struts2, they seem to be the best out there - especially since they're (AFAIK) MVC. I've considered Python and Django, which do seem REALLY nice, but I don't know much Python, and I'd rather start with something that I already know (language-wise; not framework-wise) than dive into learning a language AND a new framework. I'd REALLY like to be able to host my website via Apache, rather than using Windows Server or anything like that, as, frankly, I hate their setup. I'm not dissing it in any way, shape, or form, I'm just saying I dislike it. <3 terminal config. If there is a good reason to with Windows Server, however, I'd be willing to learn it. C# has a lot of things that Java appears not to have, including Delegates, unsigned types, and LINQ. Is there anything that Java has which can counter these?

  • How can I get my progress reviewed as a solo junior developer

    - by Oliver Hyde
    I am currently working for a 2 person company, as the solo primary developer. My boss gets the clients, mocks up some png design templates and hands them over to me. This system has been working fine and i'm really enjoying it. The types of projects I work on are for small - medium sized businesses and they usually want a CMS system. Developed from scratch i'll build a customised backend for the client to add/edit/remove categories, tags, products etc and then output them to the front end according to the design template handed to me. As time has gone on, the projects have increased in complexity, with shopping cart / ordering features and other common e-commerce type features. Again, this system has been working fine and i'm really enjoying it. My issue is my personal development as a programmer. I spend a lot of my spare time reading programming blogs, checking through stackexchange, reading suggested programming books (currently on 'The Pragmatic Programmer', really good so far), doing brain exercises (lumosity.com and khanacademy math problems), doing lots of physical exercise and other personal development type activities. I can't help but feel though, that I'm missing out on feedback, critique. My boss is great and never holds back on praise in regards to my work, but he unfortunately is either to busy to check my code, or to be honest, I don't think it's one of his specialties and so can't provide feedback. I want to know what i'm doing wrong and what i'm doing right. Should I be putting that much logic in the controller, am I modulating my code enough etc. So what I have done is developed a little 'Family Budgeting' app and tried to do it as cleanly and effectively as I currently know how. What i'm wanting to know is, is there somewhere I can submit this app, and have some seasoned developers provide feedback. It's not just a subsection of my code like 'codereview.stackexchange' appears to require, it's my entire workflow that I want critiqued. I know this is a lot to ask, and I expect the main advice given will be to look for a job within a team, which is certainly something I will look into later down the track, but for now I want to persist with my current employment situation, but just don't want to develop too many bad habits. Let me know if I can provide any further information to help clarify, or if this isn't the right place for this type of question I apologise in advance. Didn't want to use reddit as I felt this community fosters more well thought out responses.

  • New Pluralsight Course: HTML5 Canvas Fundamentals

    - by dwahlin
      I just finished up a new course for Pluralsight titled HTML5 Canvas Fundamentals that I had a blast putting together. It’s all about the client and involves a lot of pixel manipulation and graphics creation which is challenging and fun at the same time. The goal of the course is to walk you through the fundamentals, start a gradual jog into the API functions, and then start sprinting as you learn how to build a business chart canvas application from scratch that uses many of the available APIs . It’s fun stuff and very useful in a variety of scenarios including Web (desktop or mobile) and even Windows 8 Metro applications. Here’s a sample video from the course that talks about building a simple bar chart using the HTML5 Canvas:   Additional details about the course are shown next.   HTML5 Canvas Fundamentals The HTML5 Canvas provides a powerful way to render graphics, charts, and other types of visual data without relying on plugins such as Flash or Silverlight. In this course you’ll be introduced to key features available in the canvas API and see how they can be used to render shapes, text, video, images, and more. You’ll also learn how to work with gradients, perform animations, transform shapes, and build a custom charting application from scratch. If you’re looking to learn more about using the HTML5 Canvas in your Web applications then this course will break down the learning curve and give you a great start!    Getting Started with the HTML5 Canvas Introduction HTML5 Canvas Usage Scenarios Demo: Game Demos Demo: Engaging Applications Demo: Charting HTML5 Canvas Fundamentals Hello World Demo Overview of the Canvas API Demo: Canvas API Documentation Summary    Drawing with the HTML5 Canvas Introduction Drawing Rectangles and Ellipses Demo: Simple Bar Chart Demo: Simple Bar Chart with Transforms Demo: Drawing Circles Demo: Using arcTo() Drawing Lines and Paths Demo: Drawing Lines Demo: Simple Line Chart Demo: Using bezierCurveTo() Demo: Using quadraticCurveTo() Drawing Text Demo: Filling, Stroking, and Measuring Text Demo: Using Canvas Transforms with Text Drawing Images Demo: Using Image Functions Drawing Videos Demo: Syncing Video with a Canvas Summary    Manipulating Pixels  Introduction Rendering Gradients Demo: Creating Linear Gradients Demo: Creating Radial Gradients Using Transforms Demo: Getting Started with Transform Functions Demo: Using transform() and and setTransform() Accessing Pixels Demo: Creating Pixels Dynamically Demo: Grayscale Pixels Animation Fundamentals Demo: Getting Started with Animation Demo: Using Gradients, Transforms, and Animations Summary    Building a Custom Data Chart Introduction Creating the CanvasChart Object Creating the CanvasChart Shell Code Rendering Text and Gradients Rendering Data Points Text and Guide Lines Connecting Data Point Lines Rendering Data Points Adding Animation Adding Overlays and Interactivity Summary     Related Courses:

  • Freshen the RTS genre

    - by William Michael Thorley
    This isn't really a question, but a request for feedback. RPS (Rock, Paper, Scissors) RTS (Real Time Strategy) Demo version is out: The game is simple. It is an RTS. Why has it been made? Many if not most RTS’s are about economy and large numbers of unit types. The genre hasn’t actually developed the gameplay drastically from the very first RTS’s produced, some lesson have been learned, but the games are really very similar to how they have always been. RPS brings new gameplay to the RTS genre. Through three means: • New combat mechanics: RPS has two unique modes (as well as the old favourite) of resolving weapon fire. These change how combat happens, and make application of the correct units vital to success. From this comes the requirement to run Intel on your enemies. • Fixed Resource Economy: Each player has a fixed amount of energy, This means that there is a definite end to the game. You can attrition your enemy and try to outlast them, or try to outspend your opponent and destroy them. There is a limit to how fast ships can be built, through the generation of construction blocks, but energy is the fast limit on economy. • Game Modes: Game modes add victory conditions and new game pieces. The game is overseen by a controller which literally runs the game. Games are no longer line them up, gun them down. This means that new tactics must be played making skirmish games fresh with novel tactics without adding huge amounts of new game units to learn. I’ve produced RPS from the ground. I will be running a kickstarter in the near future, but right now I want feedback and input from the game developing community. Regarding the concepts, where RPS is going, the game modes, the combat mechanics. How it plays. RPS will give fresh gameplay to the genre so it must be right. It works over the internet or a LAN and supports single player games. Get it. Play it. Tell me about your games. Thank you Demo: https://dl.dropbox.com/u/51850113/RPS%20Playtest.zip Tutorials: https://dl.dropbox.com/u/51850113/RPSGamePlay.zip

  • Use of Business Parameters in BPM12c

    - by Abhishek Mittal-Oracle
    With the release of BPM12c, a new feature to use Business Parameters is introduced through which we can define a business parameter which will behave as a global variable which can be used within BPM project. Business Administrator can be the one responsible to modify the business parameters value dynamically at run-time which may bring change in BPM process flow where it is used.This feature was a part of BPM10g product and was extensively used. In BPM11g, this feature is not present currently.Business Parameters can be defined in 2 ways:1. Using Jdev to define business parameters, and 2. Using BPM workspace to define business parameters.It is important to note that business parameters need to be mapped with a valid organisation unit defined in a BPM project. If the same is not handled, exceptions like 'BPM-70702' will be thrown by BPM Engine. This is because business parameters work along with organisation defined in a BPM project.At the same time, we can use same business parameter across different organisation units with different values. Business Parameters in BPM12c has this capability to handle multiple values with different organisation units defined in a single BPM project. This enables business to re-use same business parameters defined in a BPM project across different organisations.Business parameters can be defined using the below data types:1. int2. string 3. boolean4. double While defining an business parameter, it is mandatory to provide a default value. Below are the steps to define a business parameter in Jdev: Step 1:  Open 'Organization' and click on 'Business Parameters' tab.Step 2:  Click on '+' button.Step 3: Add business parameter name, type and provide default value(mandatory).Step 4: Click on 'OK' button.Step 5: Business parameter is defined. Below are the steps to define a business parameter in BPM workspace: Step 1: Login to BPM workspace using admin-username and password.Step 2: Click on 'Administration' on the right top side of workspace.Step 3: Click on 'Business Parameters' in the left navigation panel under 'Organization'. Step 4:  Click on '+' button.Step 5: Add business parameter name, type and provide default value(mandatory).Step 6: Click on 'OK' button.Step 7: Business parameter is defined. Note: As told earlier in the blog, it is necessary to define and map a valid organization ID with predefined variable 'organizationalUnit' under data associations in an BPM process before the business parameter is used. I have created one sample PoC demonstrating the use of Business Parameters in BPM12c and it can be found here.

  • Language Club

    - by Ben Griswold
    We started a language club at work this week.  Thus far, we have a collective interest in a number of languages: Python, Ruby, F#, Erlang, Objective-C, Scala, Clojure, Haskell and Go. There are more but these 9 received the most votes. During the first few meetings we are going to determine which language we should tackle first. To help make our selection, each member will provide a quick overview of their favored language by answering the following set of questions: Why are you interested in learning “your” language(s). (There’s lots of work, I’m an MS shill, It’s hip and  fun, etc) What type of language is it?  (OO, dynamic, functional, procedural, declarative, etc) What types of problems is your language best suited to solve?  (Algorithms over big data, rapid application development, modeling, merely academic, etc) Can you provide examples of where/how it is being used?  If it isn’t being used, why not?  (Erlang was invented at Ericsson to provide an extremely fault tolerant, concurrent system.) Quick history – Who created/sponsored the language?  When was it created?  Is it currently active? Does the language have hardware support (an attempt was made at one point to create processor instruction sets specific to Prolog), or can it run as an interpreted language inside another language (like Ruby in the JVM)? Are there facilities for programs written in this language to communicate with other languages?  How does this affect its utility? Does the language have a IDE tool support?  (Think Eclipse or Visual Studio) How well is the language supported in terms of books, community and documentation? What’s the number one things which differentiates the language from others?  (i.e. Why is it cool?) How is the language applicability to us as consultants?  What would the impact be of using the language in terms of cost, maintainability, personnel costs, etc.? What’s the number one things which differentiates the language from others?  (i.e. Why is it cool?) This should provide an decent introduction into nearly a dozen languages and give us enough context to decide which single language deserves our undivided attention for the weeks to come.  Stay tuned for the winner…

  • Enhance Your Browsing with Hyperwords in Firefox

    - by Asian Angel
    While browsing it is easy to find information that you would like to know more about, convert, or translate. The Hyperwords extension provides access to these types of resources and more in Firefox. Using Hyperwords Once the extension has finished installing you will be presented with a demo video that will let you learn more about how Hyperwords works. For our first example we chose to look for more information concerning “WASP-12b” using Wikipedia. Notice the small bluish circle on the lower right of the highlighted term…it is the default access for the Hyperwords menu (access by hovering mouse over it). If you hover over the the Wikipedia (or other) link you can access the information in a scrollable popup window. Or if you prefer click on the link to view the information in a new tab. Choose the style that best suits your needs. Hyperwords is extremely useful for quick unit conversions. Suppose you want to share a news story that you have found while browsing. Highlight the title, access Hyperwords, and choose your preferred sharing source. You may need to authorize access for Hyperwords to post to your account. Once you have authorized access you can start sharing those links very easily. This is just a small sampling of Hyperwords many useful features. Preferences Hyperwords has a nice set of preferences available to help you customize it. Alter the menu popup style, add or remove menu entries, and modify other functions for Hyperwords. Conclusion Hyperwords makes a nice addition to Firefox for anyone needing quick access to search, reference, translation, and other services while browsing.

  • Scan Your Thumb Drive for Viruses from the AutoPlay Dialog

    - by Mysticgeek
    It’s always a good idea to scan someone’s flash drive for viruses when you use it on your PC. Today we look at how to use Microsoft Security Essentials to scan thumb drives via the AutoPlay dialog. Editor Note: This technique was created by our friend Ramesh Srinivasan from the winhelponline tech blog. If you haven’t done so already, download and install Microsoft Security Essentials (link below), which has earned the How-To Geek official endorsement. Next download the mseautoplay.zip (link below). Unzip the file to view its contents. Then move the msescan.vbs script file into the Windows directory. Next double-click on the mseautoplay.reg file… Click Yes to the warning dialog window asking if you’re sure you want to add to the registry. After it’s added you’ll get a confirmation message…click OK. Now when you pop in a thumb drive, when AutoPlay comes up you will have the options to scan it with MSE first. MSE starts the scan of the thumb drive…   You can use this to scan any removable media. Here is an example of the ability to scan a DVD with MSE before opening any files. You can also go into Control Panel and set it as a default option of AutoPlay. Open Control Panel, View by Large icons, and click on AutoPlay. Notice that now when you go to change the default options for different types of media, Scanning with MSE is now included in the dropdown lists. Remove Settings If you want to remove the MSE AutoPlay Handler, Ramesh was kind enough to create an undo registry file. Double-click on undo.reg from the original MSE AutoPlay folder and click yes to the message to remove the setting.   Then you will need to go into the Windows directory and manually delete the msescan.vbs script file. This is an awesome trick which will allow you to scan your thumb drives and other removable media from the AutoPlay dialog. We tested it out on XP, Vista, and Windows 7 and it works perfectly on each one.

  • The Red Gate Guide to SQL Server Team based Development Free e-book

    - by Mladen Prajdic
    After about 6 months of work, the new book I've coauthored with Grant Fritchey (Blog|Twitter), Phil Factor (Blog|Twitter) and Alex Kuznetsov (Blog|Twitter) is out. They're all smart folks I talk to online and this book is packed with good ideas backed by years of experience. The book contains a good deal of information about things you need to think of when doing any kind of multi person database development. Although it's meant for SQL Server, the principles can be applied to any database platform out there. In the book you will find information on: writing readable code, documenting code, source control and change management, deploying code between environments, unit testing, reusing code, searching and refactoring your code base. I've written chapter 5 about Database testing and chapter 11 about SQL Refactoring. In the database testing chapter (chapter 5) I cover why you should test your database, why it is a good idea to have a database access interface composed of stored procedures, views and user defined functions, what and how to test. I talk about how there are many testing methods like black and white box testing, unit and integration testing, error and stress testing and why and how you should do all those. Sometimes you have to convince management to go for testing in the development lifecycle so I give some pointers and tips how to do that. Testing databases is a bit different from testing object oriented code in a way that to have independent unit tests you need to rollback your code after each test. The chapter shows you ways to do this and also how to avoid it. At the end I show how to test various database objects and how to test access to them. In the SQL Refactoring chapter (chapter 11) I cover why refactor and where to even begin refactoring. I also who you a way to achieve a set based mindset to solve SQL problems which is crucial to good SQL set based programming and a few commonly seen problems to refactor. These problems include: using functions on columns in the where clause, SELECT * problems, long stored procedure with many input parameters, one subquery per condition in the select statement, cursors are good for anything problem, using too large data types everywhere and using your data in code for business logic anti-pattern. You can read more about it and download it here: The Red Gate Guide to SQL Server Team-based Development Hope you like it and send me feedback if you wish too.
