  • How to Create a Cinemagraph; Still Photos with Moving Elements

    - by Jason Fitzpatrick
    Cinemagraphs, still photos with moving elements, are quite a trend in photography circles. Unlike jerky animated GIFs, they’re much more fluid and subtle. Learn how to make them with this tutorial. At Photojojo! they have a detailed tutorial outlining how to create a cinemagraph that covers the planning and execution of your image. If you’ve never heard of the process before it’s pretty neat. You take a series of photographs and then, using image editing tools, mask off only the parts of the photo you want to move (like the eyes in the photos sample seen here). Then you blend the photos together and create an animated GIF where in only the small portion of the image actually moves. This is quite different than the jerky animated GIFs that result when people try to turn full motion video into an animation. Hit up the link below to see how you can create your own cinemagraphs.

  • Real Life Pixar Lamp Can’t Get Enough Of Human Interaction

    - by Jason Fitzpatrick
    This curious lamp, powered by an Arduino board and servo motors, is just as playful as the on-screen counterpart that inspired its creation. The New Zealand Herald reports on the creation of the lamp, seen in action in the video above: The project is a collaborative effort by Victoria University students Shanshan Zhou, Adam Ben-Gur and Joss Doggett, who met in a Physical Computing class. The lamp’s movements are informed by a webcam with an algorithm working behind it. Robotics and facial recognition technology enable the lamp to search for faces in the images from its webcam. When it spots a face, it follows as if trying to maintain eye contact.

  • Develop an iPad app with MonoTouch, C#, and .NET.

    - by Wallym
    Article url: http://www.devproconnections.com/article/mobile-development/ipad-ios-app-monotouch-143636 Since its release in March 2010, the iPad has taken the world by storm. Each new iPad release has launched the device further and further into our lives. Here are some interesting facts that we have seen over the past few years along with some market share analysis:The school that my teenagers attend here in Knoxville, Tennessee, was the first school in the United States to integrate the iPad into its teaching program and its curriculum. Many schools have since followed suit.There are a healthy number of applications in a variety of market segments. In fact, there is a market for iPad point-of-sale systems.The iPad is a popular device and growing more so each day. comScore states that one in four smartphone owners also owns a tablet. We also know that the iPad comprises 68 percent of the tablet market.eMarketer recently issued a report stating that the number of iPad users is expected to grow by 90 percent in the US in 2012.No matter how you slice the data, tablet usage is growing, and the iPad is currently leading the pack. The question for .NET developers is "How can I get me some of that?" Xamarin's MonoTouch offers help, by providing the means for .NET developers to leverage their C# and .NET coding skills to develop iPad applications. MonoTouch has supported the iPad since the initial release of the iOS 3.2 beta SDK all the way up to the most recent iOS SDK, which supports the iPad. In this article, we'll look at targeting the iPad and how we can take advantage of iPad-specific features in our iOS applications written with MonoTouch.I hope you enjoy the article and you find it helpful.

  • Electric Dreams: Picking Out a Vintage 1980s Computer [Video]

    - by Jason Fitzpatrick
    What if you had to pick out a 1980s era computer for use in your home today? BBC show Electric Dreams walks us through the history with a “time traveling” family. Electric Dreams is a show based on the novel premise that an average British family is starting, technologically speaking, in the 1970s and progressing over a month to the year 2000–restricted each step of the way to using technology available only in the era they are emulating. In the above video clip they’ve reached 1982 and visit the National Museum of Computing to pick out a vintage computer. It’s interesting to see the kids interact with the computer and experience programming for, presumably, the first time. Have a vintage computer memory (mine is programming on a Timex Sinclair); let’s hear about it in the comments.

  • SOA Suite 11gR1 Patch Set 2 (PS2) released today!

    - by Demed L'Her
      We just released this morning SOA Suite 11gR1 Patch Set 2 (PS2)! You can download it as usual from: OTN (main platforms only) eDelivery (all platforms)   11gR1 PS2 is delivered as a sparse installer, that is to say that it is meant to be applied on the latest full release (11gR1 PS1). The good part is that it’s great for existing PS1 users who simply need to apply the patch and run the patch assistant – the not so good part is that new users will first need to download PS1. What’s in that release? Bug fixes of course but also several significant new features. Here is a short selection of the most significant features in PS2: Spring component (for native Java extensibility and integration) SOA Partitions (to organize and manage your composites) Direct Binding (for transactional invocations to and from Oracle Service Bus) HTTP binding (for those of you trying to do away with SOAP and looking for simple GET and POST) Resequencer (for ordering out-of-order messages) WS Atomic Transactions (WS-AT) support (for propagation of transactions across heterogeneous environments) Check out the complete list of new features in PS2 for more (including links to the documentation for the above)! But maybe even more importantly we are also releasing Oracle Service Bus 11gR1 and BPM Suite 11gR1 at the same time – all on the same base platform (WebLogic Server 10.3.3)! (NB: it might take a while for all pages and caches to be updated with the new content so if you don’t find what you need today, try again soon!)   Technorati Tags: ps1,11gr1ps2,new release,oracle soa suite,oracle

Achim Sack, a fan of hardware hacking and time lapse photography, created a super tiny interval timer that works with Nikon, Canon, and Pentax DSLRs. Plug it in, snap a shot between 0.4 seconds and 18 minutes to set the interval and then leave it be. As long as you have space on the memory card and power left in the battery the camera will keep snapping pictures.

  • Oracle Enterprise Manager 11g is Here!

    - by chung.wu
    We hope that you enjoyed the launch event. If you missed it, you may still watch it via our on demand webcast, which is being produced and will be posted very shortly. 11gR1 is a major release of Oracle Enterprise Manager, and as one would expect from a big release, there are many new capabilities that appeal to a broad set of audience. Before going into the laundry list of new features, let's talk about the key themes for this release to put things in perspective. First, this release is about Business Driven Application Management. The traditional paradigm of component centric systems management simply cannot satisfy the management needs of modern distributed applications, as they do not provide adequate visibility of whether these applications are truly meeting the service level expectations of the business users. Business Driven Application Management helps IT manage applications according to the needs of the business users so that valuable IT resources can be better focused to help deliver better business results. To support Business Driven Application Management, 11gR1 builds on the work that we started in 10g to provide better support for user experience management. This capability helps IT better understand how users use applications and the experience that the applications provide so that IT can take actions to help end users get their work done more effectively. In addition, this release also delivers improved business transaction management capabilities to make it faster and easier to understand and troubleshoot transaction problems that impact end user experience. Second, this release includes strengthened Integrated Application-to-Disk Management. Every component of an application environment, from the application logic to the application server, to database, host machines and storage devices, etc... can affect end user experience. After user experience improvement needs are identified, IT needs tools that can be used do deep dive diagnostics for each of the application environment component, analyze configurations and deploy changes. Enterprise Manager 11gR1 extends coverage of key application environment components to include full support for Oracle Database 11gR2, Exadata V2, and Fusion Middleware 11g. For composite and Java application management, two key pieces of technologies, JVM Diagnostic and Composite Application Monitoring and Modeler, are now fully integrated into Enterprise Manager so there is no need to install and maintain separate tools. In addition, we have delivered the first set of integration between Enterprise Manager Grid Control and Enterprise Manager Ops Center so that hardware level events can be centrally monitored via Grid Control. Finally, this release delivers Integrated Systems Management and Support for customers of Oracle technologies. Traditionally, systems management tools and tech support were separate silos. When problems occur, administrators used internally deployed tools to try to solve the problems themselves. If they couldn't fix the problems, then they would use some sort of support website to get help from the vendor's support staff. Oracle Enterprise Manager 11g integrates problem diagnostic and remediation workflow. Administrators can use Oracle Enterprise Manager's various diagnostic tools to begin the troubleshooting process. They can also use the integrated access to My Oracle Support to look up solutions and download software patches. If further help is needed, administrators can open service requests from right within Oracle Enterprise Manager and track status update. Oracle's support staff, using Enterprise Manager's configuration management capabilities, can collect important configuration information about customer environments in order to expedite problem resolution. This tight integration between Oracle Enterprise Manager and My Oracle Support helps Oracle customers achieve a Superior Ownership Experience for their Oracle products. So there you have it. This is a brief 50,000 feet overview of Oracle Enterprise Manager 11g. We know you are hungry for the details. We are going to write about it in the coming days and weeks. For those of you that absolutely can't wait to find out more, you may download our software to try it out today. In fact, for the first time ever, the initial release of Oracle Enterprise Manager is available for both 32 and 64 bit Linux. Additional O/S ports will arrive in the coming weeks. Please stay tuned on the Oracle Enterprise Manager blog for additional updates.

  • New <%: %> Syntax for HTML Encoding Output in ASP.NET 4 (and ASP.NET MVC 2)

    - by ScottGu
    [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] This is the nineteenth in a series of blog posts I’m doing on the upcoming VS 2010 and .NET 4 release. Today’s post covers a small, but very useful, new syntax feature being introduced with ASP.NET 4 – which is the ability to automatically HTML encode output within code nuggets.  This helps protect your applications and sites against cross-site script injection (XSS) and HTML injection attacks, and enables you to do so using a nice concise syntax. HTML Encoding Cross-site script injection (XSS) and HTML encoding attacks are two of the most common security issues that plague web-sites and applications.  They occur when hackers find a way to inject client-side script or HTML markup into web-pages that are then viewed by other visitors to a site.  This can be used to both vandalize a site, as well as enable hackers to run client-script code that steals cookie data and/or exploits a user’s identity on a site to do bad things. One way to help mitigate against cross-site scripting attacks is to make sure that rendered output is HTML encoded within a page.  This helps ensures that any content that might have been input/modified by an end-user cannot be output back onto a page containing tags like <script> or <img> elements.  ASP.NET applications (especially those using ASP.NET MVC) often rely on using <%= %> code-nugget expressions to render output.  Developers today often use the Server.HtmlEncode() or HttpUtility.Encode() helper methods within these expressions to HTML encode the output before it is rendered.  This can be done using code like below: While this works fine, there are two downsides of it: It is a little verbose Developers often forget to call the HtmlEncode method New <%: %> Code Nugget Syntax With ASP.NET 4 we are introducing a new code expression syntax (<%:  %>) that renders output like <%= %> blocks do – but which also automatically HTML encodes it before doing so.  This eliminates the need to explicitly HTML encode content like we did in the example above.  Instead you can just write the more concise code below to accomplish the same thing: We chose the <%: %> syntax so that it would be easy to quickly replace existing instances of <%= %> code blocks.  It also enables you to easily search your code-base for <%= %> elements to find and verify any cases where you are not using HTML encoding within your application to ensure that you have the correct behavior. Avoiding Double Encoding While HTML encoding content is often a good best practice, there are times when the content you are outputting is meant to be HTML or is already encoded – in which case you don’t want to HTML encode it again.  ASP.NET 4 introduces a new IHtmlString interface (along with a concrete implementation: HtmlString) that you can implement on types to indicate that its value is already properly encoded (or otherwise examined) for displaying as HTML, and that therefore the value should not be HTML-encoded again.  The <%: %> code-nugget syntax checks for the presence of the IHtmlString interface and will not HTML encode the output of the code expression if its value implements this interface.  This allows developers to avoid having to decide on a per-case basis whether to use <%= %> or <%: %> code-nuggets.  Instead you can always use <%: %> code nuggets, and then have any properties or data-types that are already HTML encoded implement the IHtmlString interface. Using ASP.NET MVC HTML Helper Methods with <%: %> For a practical example of where this HTML encoding escape mechanism is useful, consider scenarios where you use HTML helper methods with ASP.NET MVC.  These helper methods typically return HTML.  For example: the Html.TextBox() helper method returns markup like <input type=”text”/>.  With ASP.NET MVC 2 these helper methods now by default return HtmlString types – which indicates that the returned string content is safe for rendering and should not be encoded by <%: %> nuggets.  This allows you to use these methods within both <%= %> code nugget blocks: As well as within <%: %> code nugget blocks: In both cases above the HTML content returned from the helper method will be rendered to the client as HTML – and the <%: %> code nugget will avoid double-encoding it. This enables you to default to always using <%: %> code nuggets instead of <%= %> code blocks within your applications.  If you want to be really hardcore you can even create a build rule that searches your application looking for <%= %> usages and flags any cases it finds as an error to enforce that HTML encoding always takes place. Scaffolding ASP.NET MVC 2 Views When you use VS 2010 (or the free Visual Web Developer 2010 Express) you’ll find that the views that are scaffolded using the “Add View” dialog now by default always use <%: %> blocks when outputting any content.  For example, below I’ve scaffolded a simple “Edit” view for an article object.  Note the three usages of <%: %> code nuggets for the label, textbox, and validation message (all output with HTML helper methods): Summary The new <%: %> syntax provides a concise way to automatically HTML encode content and then render it as output.  It allows you to make your code a little less verbose, and to easily check/verify that you are always HTML encoding content throughout your site.  This can help protect your applications against cross-site script injection (XSS) and HTML injection attacks.  Hope this helps, Scott
