JavaOne 2012 Sunday Strategy Keynote

- by Janice J. Heiss

At the Sunday Strategy Keynote, held at the Masonic Auditorium, Hasan Rizvi, EVP, Middleware and Java Development, stated that the theme for this year's JavaOne is: “Make the future Java”-- meaning that Java continues in its role as the most popular, complete, productive, secure, and innovative development platform. But it also means, he qualified, the process by which we make the future Java -- an open, transparent, collaborative, and community-driven evolution. "Many of you have bet your businesses and your careers on Java, and we have bet our business on Java," he said.Rizvi detailed the three factors they consider critical to the success of Java--technology innovation, community participation, and Oracle's leadership/stewardship. He offered a scorecard in these three realms over the past year--with OS X and Linux ARM support on Java SE, open sourcing of JavaFX by the end of the year, the release of Java Embedded Suite 7.0 middleware platform, and multiple releases on the Java EE side. The JCP process continues, with new JSR activity, and JUGs show a 25% increase in participation since last year. Oracle, meanwhile, continues its commitment to both technology and community development/outreach--with four regional JavaOne conferences last year in various part of the world, as well as the release of Java Magazine, with over 120,000 current subscribers. Georges Saab, VP Development, Java SE, next reviewed features of Java SE 7--the first major revision to the platform under Oracle's stewardship, which has included near-monthly update releases offering hundreds of fixes, performance enhancements, and new features. Saab indicated that developers, ISVs, and hosting providers have all been rapid adopters of the platform. He also noted that Oracle's entire Fusion middleware stack is supported on SE 7. The supported platforms for SE 7 has also increased--from Windows, Linux, and Solaris, to OS X, Linux ARM, and the emerging ARM micro-server market. "In the last year, we've added as many new platforms for Java, as were added in the previous decade," said Saab.Saab also explored the upcoming JDK 8 release--including Project Lambda, Project Nashorn (a modern implementation of JavaScript running on the JVM), and others. He noted that Nashorn functionality had already been used internally in NetBeans 7.3, and announced that they were planning to contribute the implementation to OpenJDK. Nandini Ramani, VP Development, Java Client, ME and Card, discussed the latest news pertaining to JavaFX 2.0--releases on Windows, OS X, and Linux, release of the FX Scene Builder tool, the JavaFX WebView component in NetBeans 7.3, and an OpenJFX project in OpenJDK. Nandini announced, as of Sunday, the availability for download of JavaFX on Linux ARM (developer preview), as well as Scene Builder on Linux. She noted that for next year's JDK 8 release, JavaFX will offer 3D, as well as third-party component integration. Avinder Brar, Senior Software Engineer, Navis, and Dierk König, Canoo Fellow, next took the stage and demonstrated all that JavaFX offers, with a feature-rich, animation-rich, real-time cargo management application that employs Canoo's just open-sourced Dolphin technology.Saab also explored Java SE 9 and beyond--Jigsaw modularity, Penrose Project for interoperability with OSGi, improved multi-tenancy for Java in the cloud, and Project Sumatra. Phil Rogers, HSA Foundation President and AMD Corporate Fellow, explored heterogeneous computing platforms that combine the CPU and the parallel processor of the GPU into a single piece of silicon and shared memory—a hardware technology driven by such advanced functionalities as HD video, face recognition, and cloud workloads. Project Sumatra is an OpenJDK project targeted at bringing Java to such heterogeneous platforms--with hardware and software experts working together to modify the JVM for these advanced applications and platforms.Ramani next discussed the latest with Java in the embedded space--"the Internet of things" and M2M--declaring this to be "the next IT revolution," with Java as the ideal technology for the ecosystem. Last week, Oracle released Java ME Embedded 3.2 (for micro-contollers and low-power devices), and Java Embedded Suite 7.0 (a middleware stack based on Java SE 7). Axel Hansmann, VP Strategy and Marketing, Cinterion, explored his company's use of Java in M2M, and their new release of EHS5, the world's smallest 3G-capable M2M module, running Java ME Embedded. Hansmaan explained that Java offers them the ability to create a "simple to use, scalable, coherent, end-to-end layer" for such diverse edge devices.Marc Brule, Chief Financial Office, Royal Canadian Mint, also explored the fascinating use-case of JavaCard in his country's MintChip e-cash technology--deployable on smartphones, USB device, computer, tablet, or cloud. In parting, Ramani encouraged developers to download the latest releases of Java Embedded, and try them out.Cameron Purdy, VP, Fusion Middleware Development and Java EE, summarized the latest developments and announcements in the Enterprise space--greater developer productivity in Java EE6 (with more on the way in EE 7), portability between platforms, vendors, and even cloud-to-cloud portability. The earliest version of the Java EE 7 SDK is now available for download--in GlassFish 4--with WebSocket support, better JSON support, and more. The final release is scheduled for April of 2013. Nicole Otto, Senior Director, Consumer Digital Technology, Nike, explored her company's Java technology driven enterprise ecosystem for all things sports, including the NikeFuel accelerometer wrist band. Looking beyond Java EE 7, Purdy mentioned NoSQL database functionality for EE 8, the concurrency utilities (possibly in EE 7), some of the Avatar projects in EE 7, some in EE 8, multi-tenancy for the cloud, supporting SaaS applications, and more.Rizvi ended by introducing Dr. Robert Ballard, oceanographer and National Geographic Explorer in Residence--part of Oracle's philanthropic relationship with the National Geographic Society to fund K-12 education around ocean science and conservation. Ballard is best known for having discovered the wreckage of the Titanic. He offered a fascinating video and overview of the cutting edge technology used in such deep-sea explorations, noting that in his early days, high-bandwidth exploration meant that you’d go down in a submarine and "stick your face up against the window." Now, it's a remotely operated, technology telepresence--"I think of my Hercules vehicle as my equivalent of a Na'vi. When I go beneath the sea, I actually send my spirit." Using high bandwidth satellite links, such amazing explorations can now occur via smartphone, laptop, or whatever platform. Ballard’s team regularly offers live feeds and programming out to schools and the world, spanning 188 countries--with embedding educators as part of the expeditions. It's technology at its finest, inspiring the next-generation of scientists and explorers!

Career guidance/advice for Junior-level Software Engineer [closed]

- by John Do

I have quite a few questions on my mind, so please bare with me. Please don't feel obligated to answer all of them, any as you choose will do. I'd appreciate if you could share some insight on any of these. Before I begin, some context: I currently have almost two years of professional experience as a Software Engineer, mainly developing software in Java. At this point, I feel that I have reached the peak in my career growth at the current company I am at and therefore I am looking for a new job, ideally again, as a Software Engineer. I have been interviewing for the past few months casually but have not had luck with companies I have a passion for. So, in no particular order - 1) In general, what are your thoughts on having graduate degrees in CS / Software Engineering. How much does it influence a salary increase, and do you think it's beneficial when working on real-world problems? I get the sense that a graduate degree in the field is trivial unless you really have a passion for research. 2) In general, in professional practice, how often had you have to write your own data structures and "complex" algorithms from scratch? In my own work, I have found myself relying mainly on third-party frameworks and the Java standard library to implement solutions as per business requirements. What are your thoughts on this? 3) In terms of resume, I feel the most ambivalent here. I want to be able to "blemish" my resume to a certain extent so that it stands out from others', but at the same time I do not want to over-exagerate my abilities. How do you strike a balance here? For example: I say that I am proficient in Java with data structures and algorithms. This is obviously a subjective and relative statement. I've taken the classes in my undergrad, and I've applied it in my work experience. What I feel as "prociency" can be seen as junior-level to others. How do you know what to say? Most of the time, recruiters (with no technical background) will be looking for keywords that stand out. This leads me to my next question (4). 4) Just from interviewing for the past few months (and getting plenty of rejections), I've come to realize that I may not be as proficient in data structures and algorithms as I thought I was. Do you think it's a good idea to remove the "proficient in java/data structure and algorithms"? I feel that being too hoenst on the resume will impede me from scoring opportunities to even have an interview with top-notch companies. What are your thoughts? 5) What is the absolute "must-have" knowledge going into a technical interview? I've been practicing several algorithmic and data sturcture problems now, and I feel that my abilities to solve arbitrary problems efficiently has not gotten significantly better. Do you think these abilities are something innate - it's either you have in you, or you don't? How can you teach yourself to learn, if you will? 6) How easy is it to go from industry/function to the next? I work mainly with backend technologies and I'm now interested in working with the frontend, i.e javascript,jquery,php or even mobile development. In your own experience, how did you not get pidgeon holed in your career? I feel that the choices you make now ultimately decide your future. As cliche as it sounds, I think it may be true. Here's what I mean: you've worked mainly as a backend engineer, people are interested in you doing the same thing since you've already accumulated experience in that function. How do get experience in a new function if people won't accept you because you don't already have it? It's a catch 22, you see... Are side projects the only real way to help you move from one function to another that you're truly interested in? For example: I could start writing my own mobile applications, even though I've worked mainly on the backend. Thanks so much for the long read. As a relatively new engineer to the real world, I am very humble and would like those who are experienced to shed some light. Thank you so much.

Dealing with "I-am-cool-and-you-are-dumb" manager [closed]

- by Software Guy

I have been working with a software company for about 6 months now. I like the projects I work on there and I really like all the people there except for 1 guy. That guy is technically smart, and he is a co-founder of the company. He is an okay guy in person (the kind you wouldn't want to care about much) but things get tricky when he is your manager. In general I am all okay but there are times when I feel I am not being treated fairly: He doesn't give much thought to when he makes mistakes and when I do something similar, he is super critical. Recently he went as far as to say "I am not sure if I can trust you with this feature". The detais of this specific case are this: I was working on this feature, and I was already a couple of hours over my normal working hours, and then I decided to stop and continue tomorrow. We use git, and I like to commit changes locally and only push when I feel they are ready. This manager insists that I push all the changes to the central repo (in case my hard drive crashes). So I push the change, and the ticket is marked as "to be tested". Next day I come in, he sits next to me and starts complaining and says that I posted above. I really didn't know what to say, I tried to explain to him that the ticket is still being worked upon but he didn't seem to listen. He interrupts me in-between when I am coding, which I do not mind, but when I do that same, his face turns like this :| and reacts as if his work was super important and I am just wasting his time. He asks me to accumulate all questions, and then ask him altogether which is not always possible, as you need a clarification before you can continue on a feature implementation. And when I am coding, he talks on the phone with his customers next to me (when he can go to the meeting room with his laptop) and doesn't care. He made me switch to a whole new IDE (from Netbeans to a commercial IDE costing a lot of money) for a really tiny feature (which I later found out was in Netbeans as well!). I didn't make a big deal out of it as I am equally comfortable working with this new IDE, but I couldn't get the science behind his obsession. He said this feature makes sure that if any method is updated by a programmer, the IDE will turn the method name to red in places where it is used. I told him that I do not have a problem since I always search for method usage in the project and make sure its updated. IDEs even have refactoring features for exactly that, but... I recently implemented a feature for a project, and I was happy about it and considering him a senior, I asked him his comments about the implementation quality.. he thought long and hard, made a few funny faces, and when he couldn't find anything, he said "ummm, your program will crash if JS is disabled" - he was wrong, since I had made sure it would work fine with default values even if JS was disabled. I told him that and then he said "oh okay". BUT, the funny thing is, a few days back, he implemented something and I objected with "But that would not run if JS is disabled" and his response was "We don't have to care about people who disable JS" :-/ Once he asked me to investigate if there was a way to modify a CMS generated menu programmatically by extending the CMS, I did my research and told him that the only was is to inject a menu item using JavaScript / jQuery and his reaction was "ah that's ugly, and hacky, not acceptable" and two days later, I see that feature implemented in the same way as I had suggested. The point is, his reaction was not respectful at all, even if what I proposed was hacky, he should be respectful, that I know what's hacky and if I am suggesting something hacky, there must be a reason for it. There are plenty of other reasons / examples where I feel I am not being treated fairly. I want your advice as to what is it that I am doing wrong and how to deal with such a situation. The other guys in the team are actually very good people, and I do not want to leave the job either (although I could, if I want to). All I want is respect and equal treatment. I have thought about talking to this guy in a face to face meeting, but that worries me that his attitude might get worse and make things more difficult for me (since he doesn't seem to be the guy who thinks he can be wrong too). I am also considering talking to the other co-founder but I am not sure how he will take it (as both founders have been friends forever). Thanks for reading the long message, I really appreciate your help.

Making your ASP.NET/HTML Websites Indic aware – accepting Tamil, Telugu, Kannada, Hindi and ot

- by Harish Ranganathan

Its been a month since I wrote my last post. Much of work has been happening around planning for Tech Ed India, the upcoming Virtual TechDays this week as well as our Developer content at the Great Indian Developer Summit 2010. Its going to be one exciting period starting this week and I am glad I would be able to meet a lot of folks who have written to me personally that they would like to catch up at Tech Ed India. For now, I had a chance to meet the Microsoft India Development Centre team that worked on the Microsoft Indic Language Input Tool (erstwhile Akshara). The team updated me that they have also released the scripts so that the Indic input feature can be encapsulated into your own websites. For example, if you are having a web page where you collect user information, you can pretty much make your site indic aware i.e. accept inputs in Tamil, Telugu, Kannada, Hindi etc., All you would need to include would be a bunch of scripts onto your web pages and you are ready to make it, like I said, “indic aware” I have built a sample web page that accepts First Name, Last Name, Address and an additional field. When it comes to accepting indic, sometimes, you may want to avoid the indic input in certain fields and accept it in English. You can specify the MicrosoftILITWebAttach="false" attribute to the Text Boxes and Text Areas (TextMode=”Multiline” in ASP.NET) so that the particular field automatically switches over to English input. Similarly, the moment you specify that the TextMode=”Password” to make it as a password field, it automatically ignores all indic recognition and shows the masked dots for the words entered. Note that, this is, when we are going for the Opt-out mode, where we are specifying that by default all the input controls would need indic awareness and we would specify for those controls where it is not required. The other mode is Opt-in mode where you would need to add a different property to the script definition i.e. attachMode=”optin” . When we do this, we need to explicitly add the MicrosoftILITWebAttach="true" attribute for every control where we need indic input. I have created a sample web page which accepts First Name, Last Name, Address and an additional input field to demonstrate the “Opt-out”. You can copy paste this into any of your web pages to check it <form id="form1" runat="server">  <input type="hidden" id="MicrosoftILITWebEmbedInfo" attachMode="optout" value="" /> <script type="text/javascript" src="http://ilit.microsoft.com/bookmarklet/script/Tamil.js" defer="defer"></script> <div> <h2> Welcome to the Registration Page </h2> <p> First Name: <asp:TextBox runat="server" ID="txtFirstName" /> <br /> <br /> Last Name: <asp:TextBox runat="server" ID="txtLastName" /> <br /> <br /> Password: <asp:TextBox runat="server" ID="txtPassword" TextMode="Password" /> <br /> <br /> Address: <asp:TextBox runat="server" ID="txtAddress" TextMode="MultiLine" Height="100" Width="200" /> <br /> <br /> English Text: <asp:TextBox ID="txtEnglishText" runat="server" MicrosoftILITWebAttach="false" /> </p> <p>  <a style="text-decoration: none" href="http://go.microsoft.com/fwlink/?LinkID=184205&clcid=0x409"><img style="border: 0px" alt="Transliteration by Microsoft" src="http://ilit.microsoft.com/bookmarklet/images/attribution.png"></a> </p> </div> </form> If you note the code snippet above, I have included the scripts in the top with the attachMode set to “optout” and for the last TextBox, I have mentioned the MicrosoftILITWebAttach="false” attribute to make it accept English input. Additionally, you also need to add the “Microsoft Indic Language Input Tool attribution image” to your web page as a courtesy to the team that developed this feature. It would basically add a image saying “Transliteration by Microsoft” similar to a Copy Right image. You can see the screen shot below where I have typed it in Tamil. In that you will notice that the password field behaves as expected and the last field accepts English Text. You can also notice the icon that comes in the first textbox that indicates that, the field is going to accept indic text. This sample is using Tamil, but you can pretty much do it for Hindi, Telugu, Kannada, Marathi, Bengali etc., The website for getting the Indic script and other instructions is http://specials.msn.co.in/ilit/WebEmbed.aspx?language=Tamil You can replace the querystring value “Tamil” to other languages as mentioned above to get the respective script. This also works for plain HTML based websites and doesn’t necessarily need you to use ASP.NET to achieve the functionality. Note that, this form is not completely localized. This is transliterated. You can add label controls for FirstName, LastName indication etc., and use the Visual Studio tools to localize and get those values from resource files. In the resource files, you can enter the text in different languages to make this a truly localized page. If you just want to download the Indic Tool Desktop version (that can be used for typing in Word, Excel, pretty much any input area), you can download it from http://specials.msn.co.in/ilit/ In the same page, there is also a web version where you can type and get text then and there if you dont want to install the desktop version. So, go ahead, download / use them in your websites and enjoy the power of Indic. Cheers !!!

XmlWriter and lower ASCII characters

- by Rick Strahl

Ran into an interesting problem today on my CodePaste.net site: The main RSS and ATOM feeds on the site were broken because one code snippet on the site contained a lower ASCII character (CHR(3)). I don't think this was done on purpose but it was enough to make the feeds fail. After quite a bit of debugging and throwing in a custom error handler into my actual feed generation code that just spit out the raw error instead of running it through the ASP.NET MVC and my own error pipeline I found the actual error. The lovely base exception and error trace I got looked like this: Error: '', hexadecimal value 0x03, is an invalid character. at System.Xml.XmlUtf8RawTextWriter.InvalidXmlChar(Int32 ch, Byte* pDst, Boolean entitize)at System.Xml.XmlUtf8RawTextWriter.WriteElementTextBlock(Char* pSrc, Char* pSrcEnd)at System.Xml.XmlUtf8RawTextWriter.WriteString(String text)at System.Xml.XmlWellFormedWriter.WriteString(String text)at System.Xml.XmlWriter.WriteElementString(String localName, String ns, String value)at System.ServiceModel.Syndication.Rss20FeedFormatter.WriteItemContents(XmlWriter writer, SyndicationItem item, Uri feedBaseUri)at System.ServiceModel.Syndication.Rss20FeedFormatter.WriteItem(XmlWriter writer, SyndicationItem item, Uri feedBaseUri)at System.ServiceModel.Syndication.Rss20FeedFormatter.WriteItems(XmlWriter writer, IEnumerable`1 items, Uri feedBaseUri)at System.ServiceModel.Syndication.Rss20FeedFormatter.WriteFeed(XmlWriter writer)at System.ServiceModel.Syndication.Rss20FeedFormatter.WriteTo(XmlWriter writer)at CodePasteMvc.Controllers.ApiControllerBase.GetFeed(Object instance) in C:\Projects2010\CodePaste\CodePasteMvc\Controllers\ApiControllerBase.cs:line 131 XML doesn't like extended ASCII Characters It turns out the issue is that XML in general does not deal well with lower ASCII characters. According to the XML spec it looks like any characters below 0x09 are invalid. If you generate an XML document in .NET with an embedded  entity (as mine did to create the error above), you tend to get an XML document error when displaying it in a viewer. For example, here's what the result of my feed output looks like with the invalid character embedded inside of Chrome which displays RSS feeds as raw XML by default: Other browsers show similar error messages. The nice thing about Chrome is that you can actually view source and jump down to see the line that causes the error which allowed me to track down the actual message that failed. If you create an XML document that contains a 0x03 character the XML writer fails outright with the error: '', hexadecimal value 0x03, is an invalid character. The good news is that this behavior is overridable so XML output can at least be created by using the XmlSettings object when configuring the XmlWriter instance. In my RSS configuration code this looks something like this:MemoryStream ms = new MemoryStream(); var settings = new XmlWriterSettings() { CheckCharacters = false }; XmlWriter writer = XmlWriter.Create(ms,settings); and voila the feed now generates. Now generally this is probably NOT a good idea, because as mentioned above these characters are illegal and if you view a raw XML document you'll get validation errors. Luckily though most RSS feed readers however don't care and happily accept and display the feed correctly, which is good because it got me over an embarrassing hump until I figured out a better solution. How to handle extended Characters? I was glad to get the feed fixed for the time being, but now I was still stuck with an interesting dilemma. CodePaste.net accepts user input for code snippets and those code snippets can contain just about anything. This means that ASP.NET's standard request filtering cannot be applied to this content. The code content displayed is encoded before display so for the HTML end the CHR(3) input is not really an issue. While invisible characters are hardly useful in user input it's not uncommon that odd characters show up in code snippets. You know the old fat fingering that happens when you're in the middle of a coding session and those invisible characters do end up sometimes in code editors and then end up pasted into the HTML textbox for pasting as a Codepaste.net snippet. The question is how to filter this text? Looking back at the XML Charset Spec it looks like all characters below 0x20 (space) except for 0x09 (tab), 0x0A (LF), 0x0D (CR) are illegal. So applying the following filter with a RegEx should work to remove invalid characters:string code = Regex.Replace(item.Code, @"[\u0000-\u0008,\u000B,\u000C,\u000E-\u001F]", ""); Applying this RegEx to the code snippet (and title) eliminates the problems and the feed renders cleanly.© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET XML Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

A Visual Studio Release Grows in Brooklyn

- by andrewbrust

Yesterday, Microsoft held its flagship launch event for Office 2010 in Manhattan. Today, the Redmond software company is holding a local launch event for Visual Studio (VS) 2010, in Brooklyn. How come information workers get the 212 treatment and developers are relegated to 718? Well, here’s the thing: the Brooklyn Marriott is actually a great place for an event, but you need some intimate knowledge of New York City to know that. NBC’s Studio 8H, where the Office launch was held yesterday (and from where SNL is broadcast) is a pretty small venue, but you’d need some inside knowledge to recognize that. Likewise, while Office 2010 is a product whose value is apparent. Appreciating VS 2010’s value takes a bit more savvy. Setting aside its year-based designation, this release of VS, counting the old Visual Basic releases, is the 10th version of the product. How can a developer audience get excited about an integrated development environment when it reaches double-digit version numbers? Well, it can be tough. Luckily, Microsoft sent Jay Schmelzer, a Group Program Manager from the Visual Studio team in Redmond, to come tell the Brooklyn audience why they should be excited. Turns out there’s a lot of reasons. Support fro SharePoint development is a big one. In previous versions of VS, that support has been anemic, at best. Shortage of SharePoint developers is a huge issue in the industry, and this should help. There’s also built in support for Windows Azure (Microsoft’s cloud platform) and, through a download, support for the forthcoming Windows Phone 7 platform. ASP.NET MVC, a “close-to-the-metal” Web development option that does away with the Web Forms abstraction layer, has a first-class presence in VS. So too does jQuery, the Open Source environment that makes JavaScript development a breeze. The jQuery support is so good that Microsoft now contributes to that Open Source project and offers IntelliSense support for it in the code editor. Speaking of the VS code editor, it now supports multi-monitor setups, zoom-in, and block selection. If you’re not a developer, this may sound confusing and minute. I’ll just say that for people who are developers these are little things that really contribute to productivity, and that translates into lower development costs. The really cool demo, though, was around Visual Studio 2010’s new debugging features. This stuff is hard to showcase, but I believe it’s truly breakthrough technology: imagine being able to step backwards in time to see what might have caused a bug. Cool? Now imagine being able to do that, even if you weren’t the tester and weren’t present while the testing was being done. Then imagine being able to see a video screen capture of what the tester was doing with your app when the bug occurred. VS 2010 allows all that. This could be the demise of the IWOMM (“it works on my machine”) syndrome. After the keynote, I asked Schmelzer if any of Microsoft’s competitors have debugging tools that come close to VS 2010’s. His answer was an earnest “we don’t think so.” If that’s true, that’s a big deal, and a huge advantage for developer teams who adopt it. It will make software development much cheaper and more efficient. Kind of like holding a launch event at the Brooklyn Marriott instead of 30 Rock in Manhattan! VS 2010 (version 10) and Office 2010 (version 14) aren’t the only new product versions Microsoft is releasing right now. There’s also SQL Server 2008 R2 (version 10.5), Exchange 2010 (version 8, I believe), SharePoint 2010 (version 4) and, of course, Windows 7. With so many new versions at such levels of maturity, I think it’s fair to say Microsoft has reached middle-age. How does a company stave off a potential mid-life crisis, especially when with young Turks like Google coming along and competing so fiercely? Hard to say. But if focusing on core value, including value that’s hard to play into a sexy demo, is part oft the answer, then Microsoft’s doing OK. And if some new tricks, like Windows Phone 7, can gain some traction, that might round things out nicely. Are the legacy products old tricks, or are they revised classics? I honestly don’t know, because it’s the market’s prerogative to pass that judgement. I can say this though: based on today’s show, I think Microsoft’s been doing its homework.

Click event is working in general browsers butt that is needed for iOS and Android, useFastClick is (touch + mouse click). Moreover if you have this event alot in your project you can turn useFastClick off in mobileinit event: $(document).bind("mobileinit", function () { $.mobile.useFastClick = false; }); vclick event is needed to support touch events to make the page changes to happen faster, and to perform the URL hiding. So you need to change something like this $('btnShow').live("click", function (evt) { To : $('btnShow').live("vclick", function (evt) { For more information : http://jquerymobile.com/test/docs/api/globalconfig.html Here you can find full example in this case : <!DOCTYPE ><html xmlns="http://www.w3.org/1999/xhtml"><head> <link rel="stylesheet" href="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.css" /> <script src="http://code.jquery.com/jquery-1.6.1.min.js"></script> <script src="http://code.jquery.com/mobile/1.0b1/jquery.mobile-1.0b1.min.js"></script> <script type="text/javascript"> //Here you need to use vclick instead of click event $('ul[id="MylistView"] a').live("vclick", function (evt) { alert('list click'); }); </script> <title></title></head><body> <div id="FirstPage" data-role="page" data-theme="b"> <div data-role="header"> <h1> Page Title</h1> </div> <div data-role="content"> <ul id="MylistView" data-role="listview" data-theme="g"> <li><a href="#SecondPage">Acura</a></li> <li><a href="#SecondPage">Audi</a></li> <li><a href="#SecondPage">BMW</a></li> </ul> </div> <div data-role="footer"> <h4> Page Footer</h4> </div> </div> <div id="SecondPage" data-role="page" data-theme="b" > <div data-role="header" > <h1> Page Title</h1> </div> Second Page <div data-role="footer"> <h4> Page Footer</h4> </div> </div></body></html> Hope that helps.

Are IE9 really good ?

- by anirudha

IE9 started a campaign for kill IE6 from the core because they know that IE6 is a big trouble or problem for them for promote 9 version of IE. so they started a campaign for killing IE6. next time they kill IE 7 , 8,9 whenever they found this old version have a big problem for them to promote next version of IE. Why they not make a update system who automatically update the browser and tell user to restart and update goes installed in the user system. well IE9 should learn from all other that they have very well design auto-update system who never give user in trouble that your browser goes old. Chrome and Firefox both update themselves and say user restart to enjoy another good version. in IE6 a big problem is that updates. no one sure that they installed new version of IE6 without any hassles and update goes install without any problem because they really know or care about “you need this to install this and this for this” so they thing “why I update IE whenever I am unsure that my browser goes update and I have no problem again” so they do nothing because their work done with no problem because common person used high profile application who work even in IE6. so they do nothing. IE6 countdown website have designed a banner for warn or force user to upgrade to next version of IE. well there is no good reason for put the banner on website some of reason are:- Windows 7 comes with pre-installed IE8 and Vista comes with upgrade version them IE6 so that is sure that you force a user who have Windows XP [luna] and if they want to upgrade IE then they can get IE8 not version 9 because IE9 is design for Windows 7 or Vista Service pack 2. so What is the use of update when user still have a outdate version too because IE8 is old version and not have any capability of HTML5 so forcing user by using the banner have no sense. I am not know why they all listed on website put the banner on their own website. it’s good that you offer user what they want instead of giving them a outdate version of IE again. My means to give a user list of browser they can try to enhance their browser experience instead of only IE. IE9 build upon WPF and they spent more time on using WPF in IE instead of making user experience browser. many thing is designed wrongly in IE first thing is tabs. the tabs in chrome are bigger and easily to move and same in Firefox even not have smooth tabbing. IE have same tabbing as chrome have but leak a point that it’s too small. if you really want to move then sometime they create a problem that they going elsewhere from the current instance of IE. Chrome have a big buttons, tabs and menu to enhance browser experience and Firefox have a good feature that you can make them bigger or small. you can put the icon for add-ons on the toolbar for easily use but IE have no relation with customization so we never can thinking about that. When chrome provide lot’s of extensions and a webstore for browser application and same feature in Firefox can be seen then there is no plugin in IE. really you can see their IE addons Website where no plugin listed for web development. even in the category or tag. as a response from many blog there is new for developer that new version of IE9 developer tool. well IE9 have three new tabs a blogger tell on their blog. when I trying them I found many thing but I still unable to edit the Css from the HTML tab and no plugin I found I can get to enhance IE9 web development. something more other provide never IE9 give me like personas , customization , browser extension or any other they used to tell a small thing customization . IE9 still have some problem with JavaScript that when I use Firefox and chrome and logout in both then my cookie is deleted but in IE it’s not done. it’s show me that IE9 still have different from other not for good thing even some bad thing too. When I trying to read a article that is written in Hindi using Unicode font I found that they show many thing misspelled. there is three Sha in Hindi but they all goes wrong in IE. the misprint thing is not that the writing for the articles goes wrong. it’s problem or browser to rendering a font. the Firefox and chrome not give me this problem even opera render the font in italic style by decrease the font-size but all those work perfect. in Pwn2Own the apple’s safari and IE9 both are hacked. this is a awesome news for whose who thing that open-source is lose in Security and close-source is highly-secured software. well this is not a good parameter for talking about software. it’s should depend how much application tested and used. because more testing and more use of application make them better. I appreciate IE to making their new version 9 and good luck for them. there is a another matter that I personally found nothing on them.

Navigate Quickly with JustCode and Ctrl+Click

Ctrl + Click is a widely used shortcut for Go To Definition in many development environments but not in Visual Studio. We, the JustCode team, find it really useful so we added it to Visual Studio. But we didn't stop there - we improved it even further. Read on to find the details. With JustCode you get an enhanced Go To Definition. By default you can execute it in the Visual Studio editor using one of the following shortcuts: Middle Click, Ctrl+Left Click, F12, Ctrl+Enter, Ctrl+B. The first usage of this feature is not much different from the default Visual Studio Go To Definition command use it where a member, type, method, property, etc is used to navigate to the definition of that item. For example, if you have this method: public void Start() { lion = new Lion(); lion.Roar(); } If you hold Ctrl and click on the usage of the lion you will go to the lion member definition. If you hold Ctrl and click on the Lion you will go to the Lion class definition. What we added is the ability to easily find all the usages of the item you just navigated to. For example: public class Lion { public void Roar() { Console.WriteLine("Rhaaaar"); } } If you hold Ctrl and click on the Lion definition you will see all the usages of the Lion type; if you click on the Roar method definition you will see all the usages of the Roar method: And if there is only one usage you will get automatically to that usage. In the examples I use C#, but it works also in VB.NET, JavaScript, ASP.NET and XAML. Why we like this feature? Let me first start with how the Ctrl+Click (or Go To Definition command) is used. We noticed that developers use it especially in what we call "code browsing sessions". In simple words this is when you browse around the code looking for a bug, just reading the code or searching for something. Sounds familiar? In our experience when you go to the definition of some item you often want to know more about it and the first thing you need is to find its usages. With JustCode this is just one click away. Why Ctrl+Click/Middle Click over F12/Ctrl+Enter/Ctrl+B? Actually you can use all of them. But during these "code browsing sessions" we noticed that most developers use the mouse. So the mouse is already in use and pressing Ctrl+Click (or the Middle Click) is so natural. During heavy coding sessions or if you are a keyboard type developer F12 (or any of the other keyboard shortcuts) is the key. We really use heavily this feature not only in our team but in the whole company. It saves us a bit of time many times a day. And it adds up. We hope you will like it too. Your feedback is more than welcome for us. P.S. If you dont want JustCode to capture the Ctrl+Click and the Middle Click in the editor, you can change that in JustCode->Options->General in the Navigation group. Keyboard shortcuts can be reassigned using the Visual Studio keyboard shortcuts editor.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

How to Point sprite's direction towards Mouse or an Object [duplicate]

- by Irfan Dahir

This question already has an answer here: Rotating To Face a Point 1 answer I need some help with rotating sprites towards the mouse. I'm currently using the library allegro 5.XX. The rotation of the sprite works but it's constantly inaccurate. It's always a few angles off from the mouse to the left. Can anyone please help me with this? Thank you. P.S I got help with the rotating function from here: http://www.gamefromscratch.com/post/2012/11/18/GameDev-math-recipes-Rotating-to-face-a-point.aspx Although it's by javascript, the maths function is the same. And also, by placing: if(angle < 0) { angle = 360 - (-angle); } doesn't fix it. The Code: #include <allegro5\allegro.h> #include <allegro5\allegro_image.h> #include "math.h" int main(void) { int width = 640; int height = 480; bool exit = false; int shipW = 0; int shipH = 0; ALLEGRO_DISPLAY *display = NULL; ALLEGRO_EVENT_QUEUE *event_queue = NULL; ALLEGRO_BITMAP *ship = NULL; if(!al_init()) return -1; display = al_create_display(width, height); if(!display) return -1; al_install_keyboard(); al_install_mouse(); al_init_image_addon(); al_set_new_bitmap_flags(ALLEGRO_MIN_LINEAR | ALLEGRO_MAG_LINEAR); //smoother rotate ship = al_load_bitmap("ship.bmp"); shipH = al_get_bitmap_height(ship); shipW = al_get_bitmap_width(ship); int shipx = width/2 - shipW/2; int shipy = height/2 - shipH/2; int mx = width/2; int my = height/2; al_set_mouse_xy(display, mx, my); event_queue = al_create_event_queue(); al_register_event_source(event_queue, al_get_mouse_event_source()); al_register_event_source(event_queue, al_get_keyboard_event_source()); //al_hide_mouse_cursor(display); float angle; while(!exit) { ALLEGRO_EVENT ev; al_wait_for_event(event_queue, &ev); if(ev.type == ALLEGRO_EVENT_KEY_UP) { switch(ev.keyboard.keycode) { case ALLEGRO_KEY_ESCAPE: exit = true; break; /*case ALLEGRO_KEY_LEFT: degree -= 10; break; case ALLEGRO_KEY_RIGHT: degree += 10; break;*/ case ALLEGRO_KEY_W: shipy -=10; break; case ALLEGRO_KEY_S: shipy +=10; break; case ALLEGRO_KEY_A: shipx -=10; break; case ALLEGRO_KEY_D: shipx += 10; break; } }else if(ev.type == ALLEGRO_EVENT_MOUSE_AXES) { mx = ev.mouse.x; my = ev.mouse.y; angle = atan2(my - shipy, mx - shipx); } // al_draw_bitmap(ship,shipx, shipy, 0); //al_draw_rotated_bitmap(ship, shipW/2, shipH/2, shipx, shipy, degree * 3.142/180,0); al_draw_rotated_bitmap(ship, shipW/2, shipH/2, shipx, shipy,angle, 0); //I directly placed the angle because the allegro library calculates radians, and if i multiplied it by 180/3. 142 the rotation would go hawire, not would, it actually did. al_flip_display(); al_clear_to_color(al_map_rgb(0,0,0)); } al_destroy_bitmap(ship); al_destroy_event_queue(event_queue); al_destroy_display(display); return 0; } EDIT: This was marked duplicate by a moderator. I'd like to say that this isn't the same as that. I'm a total beginner at game programming, I had a view at that other topic and I had difficulty understanding it. Please understand this, thank you. :/ Also, while I was making a print of what the angle is I got this... Here is a screenshot:http://img34.imageshack.us/img34/7396/fzuq.jpg Which is weird because aren't angles supposed to be 360 degrees only?

What's New in SGD 5.1?

- by Fat Bloke

Oracle announced the latest version of Secure Global Desktop (SGD) this week with 3 major themes: Support for Android devices; Support for Desktop Chrome clients; Support for Oracle Unified Directory. I'll talk about the new features in a moment, but a bit of context first: Oracle SGD - what, how and why? Oracle Secure Global Desktop is Oracle's secure remote access product which allows users on almost any device, to access almost any type application which is hosted in the data center, from almost any location. And it does this by sitting on the edge of the datacenter, between the user and the applications: This is actually a really smart environment for an increasing number of use cases where: Users need mobility of location AND device (i.e. work from anywhere); IT needs to ensure security of applications and data (of course!) The application requires an end-user environment which can't be guaranteed and IT may not own the client platform (e.g. BYOD, working from home, partners or contractors). Oracle has a a specific interest in this of course. As the leading supplier of enterprise applications, many of Oracle's customers, and indeed Oracle itself, fit these criteria. So, as an IT guy rolling out an application to your employees, if one of your apps absolutely needs, say, IE10 with Java 6 update 32, how can you be sure that the user population has this, especially when they're using their own devices? In the SGD model you, the IT guy, can set up, say, a Windows Server running the exact environment required, and then use SGD to publish this app, without needing to worry any further about the device the end user is using. What's new? So back to SGD 5.1 and what is new there: Android devices Since we introduced our support for iPad tablets in SGD 5.0 we've had a big demand from customers to extend this to Android tablets too, and so we're pleased to announce that 5.1 supports Android 4.x tablets such as Nexus 7 and 10, and the Galaxy Tab. Here's how it works, with screenshots from my Nexus 7: Simply point your browser to the SGD server URL and login; The workspace is the list of apps that the admin has deemed ok for you to run. You click on an application to run it (here's Excel and Oracle E-Business Suite): There's an extended on-screen keyboard (extended because desktop apps need keys that don't appear on a tablet keyboard such as ctrl, WIndow key, etc) and touch gestures can be mapped to desktop events (such as tap and hold to right click) All in all a pretty nice implementation for Android tablet users. Desktop Chrome Browsers SGD has always been designed around using a browser to access your applications. But traditionally, this has involved using Java to deliver the SGD client component. With HTML5 and Javascript engines becoming so powerful, we thought we'd see how well a pure web client could perform with desktop apps. And the answer was, surprisingly well. So with this release we now offer this additional way of working, which can be enabled by a simple bit of configuration. Here's a Linux desktop running in a tab in Chrome. And if you resize the browser window, the Linux desktop is resized by SGD too. Very cool! Oracle Unified Directory As I mentioned above, a lot of Oracle users already benefit from SGD. And a lot of Oracle customers use Oracle Unified Directory as their Enterprise and Carrier grade user directory. So it makes a lot of sense that SGD now supports this LDAP directory for both Authentication and as a means to determine which users get which applications, e.g. publish the engineering app to the guys in the Development group, but give everyone E-Business Suite to let them do their expenses. Summary With new devices, and faster 4G networking becoming more prevalent, the pressure for businesses to move to a increasingly mobile enterprise is stronger than ever. SGD is good for users, and even better for IT. By offering the user the ability to work from anywhere, and IT the control and security they need, everyone wins with SGD. To try this for yourself, download SGD 5.1 (look under Desktop Virtualization Products) from the Oracle Software Delivery Cloud or if you're an existing customer, get it from My Oracle Support. -FB

ControlTemplate Exception: "XamlParseException: Cannot find a Resource with the Name/Key"

- by akaphenom

If I move the application resources to a UserControl resources everythgin runs groovy. I still don't understand why. I noticed that my application object MyApp did more than inherit from Application it loaded an XAML for the main template and connected all the plumbing. So I decided to create a user control to remove the template from the applciation (thinking there may be an even order issue not allowing my resource to be found). namespace Module1 type Template() as this = //inherit UriUserControl("/FSSilverlightApp;component/template.xaml", "") inherit UriUserControl("/FSSilverlightApp;component/templateSimple.xaml", "") do Application.LoadComponent(this, base.uri) let siteTemplate : Grid = (this.Content :?> FrameworkElement) ? siteTemplate let nav : Frame = siteTemplate ? contentFrame let pages : UriUserControl array = [| new Module1.Page1() :> UriUserControl ; new Module1.Page2() :> UriUserControl ; new Module1.Page3() :> UriUserControl ; new Module1.Page4() :> UriUserControl ; new Module1.Page5() :> UriUserControl ; |] do nav.Navigate((pages.[0] :> INamedUriProvider).Uri) |> ignore type MyApp() as this = inherit Application() do Application.LoadComponent(this, new System.Uri("/FSSilverlightApp;component/App.xaml", System.UriKind.Relative)) do System.Windows.Browser.HtmlPage.Plugin.Focus() this.RootVisual <- new Template() ; // test code to check for the existance of the ControlTemplate - it exists let a = Application.Current.Resources.MergedDictionaries let b = a.[0] let c = b.Count let d : ControlTemplate = downcast c.["TransitioningFrame"] () "/FSSilverlightApp;component/templateSimple.xaml" <UserControl x:Class="Module1.Template" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" > <Grid HorizontalAlignment="Center" Background="White" Name="siteTemplate"> <StackPanel Grid.Row="3" Grid.Column="2" Name="mainPanel">  <navigation:Frame Name="contentFrame" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Template="{StaticResource TransitioningFrame}"/> </StackPanel> </Grid> </UserControl> "/FSSilverlightApp;component/App.xaml" <Application xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" x:Class="Module1.MyApp"> <Application.Resources> <ResourceDictionary> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/FSSilverlightApp;component/TransitioningFrame.xaml" /> </ResourceDictionary.MergedDictionaries> </ResourceDictionary> </Application.Resources> </Application> "/FSSilverlightApp;component/TransitioningFrame.xaml" <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:navigation="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Navigation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ControlTemplate x:Key="TransitioningFrame" TargetType="navigation:Frame"> <Border Background="Olive" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="5" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <ContentPresenter Cursor="{TemplateBinding Cursor}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" Content="{TemplateBinding Content}"/> </Border> </ControlTemplate> </ResourceDictionary> Unfortunately that did not work.

SOLVED: deploying applications that use LINQ to Entities.

HI COMUNITY!!!! I want to use L2E since it s very convenient to my company's apps, I created a demo project, the demo does run on every machine but when I, lets say, press a button that has some code that uses the entity I get this error: specified store provider cannot be found in the configuration, or is not valid. note that I get this error only on machines that does not have VS2008 installed, on these machines (the ones with VS2008) the demo works well. any advice is appreciated.

HELP: deploying applications that use LINQ to Entities.

- by Luiscencio

HI COMUNITY!!!! I want to use L2E since it s very convenient to my company's apps, I created a demo project, the demo does run on every machine but when I, lets say, press a button that has some code that uses the entity I get this error: specified store provider cannot be found in the configuration, or is not valid. note that I get this error only on machines that does not have VS2008 installed, on these machines (the ones with VS2008) the demo works well. any advice is appreciated. I am using MySql server with Mysql Conector 6.3 and the model is created with ADO.Net entitiy model. EDIT here is the complete error trace: See the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box. ************** Exception Text ************** System.ArgumentException: The specified store provider cannot be found in the configuration, or is not valid. ---> System.ArgumentException: Unable to find the requested .Net Framework Data Provider.

Bogus InvalidOperationException (in a DataServiceRequestException)

- by Andrei Rinea

I am having a hard time with ADO.NET Data Services (formerly code-named Astoria) as it gives me a bogus exception when I try to insert a new entity from the silverlight client and trying in a clean project (the same code) doesn't. In both cases, however, data is correctly inserted into the database. Using Fiddler (an HTTP debugger I could see that there is no problem in the HTTP communication as I will show later in this question. The code : var ctx = new MyProject123Entities(new Uri("http://andreiri/MyProject.Data/Data.svc")); var i = new Zone() { Data = DateTime.Now, IdElement = 1 }; ctx.AddToZone(i); i.StareZone = new StareZone() { IdStareZone = 1 }; ctx.AttachTo("StareZone", i.StareZone); ctx.SetLink(i, "StareZone", i.StareZone); i.TipZone = new TipZone() { IdTipZone = 1 }; ctx.AttachTo("TipZone", i.TipZone); ctx.SetLink(i, "TipZone", i.TipZone); i.User = new User() { IdUser = 2 }; ctx.AttachTo("User", i.User); ctx.SetLink(i, "User", i.User); ctx.BeginSaveChanges(r =] ctx.EndSaveChanges(r), null); when run the last line (ctx.EndSaveChanges(r)) will throw the following exception : System.Data.Services.Client.DataServiceRequestException was unhandled by user code Message="An error occurred while processing this request."

Programming an Android Button to update EditText views

- by bergler77

Ok guys, I have a button in android that i'm trying to use to update 8 EditText Views with different random numbers. Everything works up until I click the button. It appears I am missing a resource according to the debugger, but I'm not sure what. I've tried several different ways of implementing the button. Here is what I have after looking at several posts. import java.util.Random; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; public class MyCharNewChar extends MyCharActivity { private OnClickListener randomButtonListener = new OnClickListener(){ public void onClick(View v) { //Button creates a set of random numbers and updates the values //of the EditText views. Random rand = new Random(); int STR = 1 + rand.nextInt(12); int AGI = 1 + rand.nextInt(12); int DEX = 1 + rand.nextInt(12); int WIS = 1 + rand.nextInt(12); int INT = 1 + rand.nextInt(12); int CON = 1 + rand.nextInt(12); int HP = 1 + rand.nextInt(20); int AC = 1 + rand.nextInt(6); EditText str = (EditText) findViewById(R.id.str); str.setText(STR); EditText agi = (EditText) findViewById(R.id.agi); agi.setText(AGI); EditText dex = (EditText) findViewById(R.id.dex); dex.setText(DEX); EditText wis = (EditText) findViewById(R.id.wis); wis.setText(WIS); EditText intel = (EditText) findViewById(R.id.intel); intel.setText(INT); EditText con = (EditText) findViewById(R.id.con); con.setText(CON); EditText hp = (EditText) findViewById(R.id.baseHP); hp.setText(HP); EditText ac = (EditText) findViewById(R.id.baseAC); ac.setText(AC); } }; @Override public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.newchar); Button randomButton = (Button) findViewById(R.id.randomButton); randomButton.setOnClickListener(randomButtonListener); } } Here is the xml: <?xml version="1.0" encoding="utf-8"?> <LinearLayout

Content Container Overlaps Menu?

- by Harold

I'm currently working on a Joomla template using CSS divs. I have a header set up with our logo image in a div floated to the left, an adspace floated to the right, and the menu bar on the bottom. My content is divided into three div columns that are contained in "container.": the left column is floated left, the center is not floated, and the right is floated to the right. The problem is the "container" for the three content divs is overlapping the menu, as you can see in this image: http://www.ndpstudentcouncil.org/images/shot1.png Here's the HTML code: > <body> <div id="backdrop"> <div > id="wrapper"> <div id="header"> > <div id="topimage"> </div> > <div id="adspace1"><jdoc:include > type="modules" name="Ad Space #1" /> > This will be the location for our > "newsflash" items. </div> > > <div id="ddtopmenubar" > class="mattblackmenu"> > <ul> > <li><a href="http://www.ndpstudentcouncil.org">Home</a></li> > <li><a href="http://www.dynamicdrive.com/new.htm" rel="ddsubmenu1">DHTML</a></li> > <li><a href="http://www.dynamicdrive.com/style/" > rel="ddsubmenu2">CSS</a></li> > <li><a href="http://www.dynamicdrive.com/forums/">Forums</a></li> > <li><a href="http://tools.dynamicdrive.com/" > rel="ddsubmenu3">Web Tools</a></li> > </ul> > <script type="text/javascript" src="js/ddlevelsmenu.js"> > ddlevelsmenu.setup("ddtopmenubar", "topbar") > //ddlevelsmenu.setup("mainmenuid", > "topbar|sidebar") > </script> > <ul id="ddsubmenu1" class="ddsubmenustyle"> > <li><a href="#">Item 1a</a></li> > <li><a href="#">Item 2a</a></li> > <li><a href="#">Item Folder 3a</a> > <ul> > <li><a href="#">Sub Item 3.1a</a></li> > </ul> > </li> > <li><a href="#">Item 4a</a></li> > <li><a href="#">Item Folder 5a</a> > <ul> > <li><a href="#">Sub Item 5.1a</a></li> > <li><a href="#">Item Folder 5.2a</a> > <ul> > <li><a href="#">Sub Item 5.2.1a</a></li> > <li><a href="#">Sub Item 5.2.2a</a></li> > </ul> > </li> > </ul> > </a> > </li> > <li><a href="#">Item 6a</a></li> > </ul> </div> </div> > <div id="container"> <script language="javascript"> > matchHeight=function(){ > var divs,contDivs,maxHeight,divHeight,d; > // get all <div> elements in the document > divs=document.getElementsByTagName('div'); > contDivs=[]; > // initialize maximum height value > maxHeight=0; > // iterate over all <div> elements in the document > for(var i=0;i<divs.length;i++){ > // make collection with <div> elements with class attribute > 'container' > if(/\bcontainer\b/.test(divs[i].className)){ > d=divs[i]; > contDivs[contDivs.length]=d; > // determine height for <div> element > if(d.offsetHeight){ > divHeight=d.offsetHeight; > } > else if(d.style.pixelHeight){ > divHeight=d.style.pixelHeight; > } > // calculate maximum height > maxHeight=Math.max(maxHeight,divHeight); > } > } > // assign maximum height value to all of container <div> elements > for(var i=0;i<contDivs.length;i++){ > contDivs[i].style.height=maxHeight; > } > } > // execute function when page loads > window.onload=function(){ > if(document.getElementsByTagName){ > matchHeight(); > } > } > </script> <div id="left"> > <jdoc:include type="modules" name="left" /> </div> <div > id="middle"> > <jdoc:include type="component" /> </div> <div id="right"> > <jdoc:include type="modules" name="right" /> > </div> > </div> > <div id="footer" class="clear"><jdoc:include > type="modules" name="footer" /> > © 2010 NDP Student Council<br > />Website Development Subcommitee > </div> </div> </div> </body> The CSS: > #backdrop { width:100%; height:100%; background: #FFFFFF > url(../images/gradient.jpg) repeat-x; > } > > #wrapper { margin:auto; width:95%; height:95%; border-right:thick solid > black; border-bottom:thick solid > black; border-top:thick solid black; > border-left:thick solid black; > background-color:white; } > > #header { height:131px; width:100%; background-color: #FFFFFF; > border-bottom:thick solid black; } > > #topimage { float:left; height:131px; width:63%; > background-image: > url("../images/ndps2.png"); > background-repeat:no-repeat; } > > #adspace1 { float:right; width:27%; height:131px; } > > #container { clear:both; } > #left{ width:20%; float:left; padding:5px; text-align:center; } > > #middle{ width:60%; padding:5px; text-align:center; } > > #right{ float:right; width:20%; padding:5px; text-align:right; } > #footer { border-top:thick solid black; width:100%; > text-align:center; } .clear { > clear:both; } Here is the CSS for the menu itself, which is from DynamicDrive.com: > .mattblackmenu ul{ margin: 0; padding: > 0; font: bold 12px Verdana; > list-style-type: none; border-bottom: > 1px solid gray; background: #414141; > overflow: hidden; width: 100%; > clear:both; } > > .mattblackmenu li{ display: inline; > margin: 0; } > > .mattblackmenu li a{ float: left; > display: block; text-decoration: none; > margin: 0; padding: 6px 8px; /*padding > inside each tab*/ border-right: 1px > solid white; /*right divider between > tabs*/ color: white; background: > #414141; Thanks for the help!

Problem with updating data in asp .NET MVC 2 application

- by Bojan

Hello everyone, i am just getting started with asp .NET MVC 2 applications and i stumbled upon a problem. I'm having trouble updating my tables. The debugger doesn't report any error, it just doesn't do anything... I hope some can help me out. Thank you for your time. This is my controller code... public ActionResult Edit(int id) { var supplierToEdit = (from c in _entities.SupplierSet where c.SupplierId == id select c).FirstOrDefault(); return View(supplierToEdit); } // // POST: /Supplier/Edit/5 [AcceptVerbs(HttpVerbs.Post)] public ActionResult Edit(Supplier supplierToEdit) { if (!ModelState.IsValid) return View(); try { var originalSupplier = (from c in _entities.SupplierSet where c.SupplierId == supplierToEdit.SupplierId select c).FirstOrDefault(); _entities.ApplyPropertyChanges(originalSupplier.EntityKey.EntitySetName, supplierToEdit); _entities.SaveChanges(); // TODO: Add update logic here return RedirectToAction("Index"); } catch { return View(); } } This is my View ... <h2>Edit</h2> <% using (Html.BeginForm()) {%> <%= Html.ValidationSummary(true) %> <fieldset> <legend>Fields</legend> <div class="editor-label"> <%= Html.LabelFor(model => model.CompanyName) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.CompanyName) %> <%= Html.ValidationMessageFor(model => model.CompanyName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.ContactName) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.ContactName) %> <%= Html.ValidationMessageFor(model => model.ContactName) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.ContactTitle) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.ContactTitle) %> <%= Html.ValidationMessageFor(model => model.ContactTitle) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Address) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Address) %> <%= Html.ValidationMessageFor(model => model.Address) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.City) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.City) %> <%= Html.ValidationMessageFor(model => model.City) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.PostalCode) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.PostalCode) %> <%= Html.ValidationMessageFor(model => model.PostalCode) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Country) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Country) %> <%= Html.ValidationMessageFor(model => model.Country) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Telephone) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Telephone) %> <%= Html.ValidationMessageFor(model => model.Telephone) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.Fax) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.Fax) %> <%= Html.ValidationMessageFor(model => model.Fax) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.HomePage) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.HomePage) %> <%= Html.ValidationMessageFor(model => model.HomePage) %> </div> <p> <input type="submit" value="Save" /> </p> </fieldset> <% } %> <div> <%= Html.ActionLink("Back to List", "Index") %> </div>

Array sorting efficiency... Beginner need advice

- by SoleSoft

I'll start by saying I am very much a beginner programmer, this is essentially my first real project outside of using learning material. I've been making a 'Simon Says' style game (the game where you repeat the pattern generated by the computer) using C# and XNA, the actual game is complete and working fine but while creating it, I wanted to also create a 'top 10' scoreboard. The scoreboard would record player name, level (how many 'rounds' they've completed) and combo (how many buttons presses they got correct), the scoreboard would then be sorted by combo score. This led me to XML, the first time using it, and I eventually got to the point of having an XML file that recorded the top 10 scores. The XML file is managed within a scoreboard class, which is also responsible for adding new scores and sorting scores. Which gets me to the point... I'd like some feedback on the way I've gone about sorting the score list and how I could have done it better, I have no other way to gain feedback =(. I know .NET features Array.Sort() but I wasn't too sure of how to use it as it's not just a single array that needs to be sorted. When a new score needs to be entered into the scoreboard, the player name and level also have to be added. These are stored within an 'array of arrays' (10 = for 'top 10' scores) scoreboardComboData = new int[10]; // Combo scoreboardTextData = new string[2][]; scoreboardTextData[0] = new string[10]; // Name scoreboardTextData[1] = new string[10]; // Level as string The scoreboard class works as follows: - Checks to see if 'scoreboard.xml' exists, if not it creates it - Initialises above arrays and adds any player data from scoreboard.xml, from previous run - when AddScore(name, level, combo) is called the sort begins - Another method can also be called that populates the XML file with above array data The sort checks to see if the new score (combo) is less than or equal to any recorded scores within the scoreboardComboData array (if it's greater than a score, it moves onto the next element). If so, it moves all scores below the score it is less than or equal to down one element, essentially removing the last score and then places the new score within the element below the score it is less than or equal to. If the score is greater than all recorded scores, it moves all scores down one and inserts the new score within the first element. If it's the only score, it simply adds it to the first element. When a new score is added, the Name and Level data is also added to their relevant arrays, in the same way. What a tongue twister. Below is the AddScore method, I've added comments in the hope that it makes things clearer O_o. You can get the actual source file HERE. Below the method is an example of the quickest way to add a score to follow through with a debugger. public static void AddScore(string name, string level, int combo) { // If the scoreboard has not yet been filled, this adds another 'active' // array element each time a new score is added. The actual array size is // defined within PopulateScoreBoard() (set to 10 - for 'top 10' if (totalScores < scoreboardComboData.Length) totalScores++; // Does the scoreboard even need sorting? if (totalScores > 1) { for (int i = totalScores - 1; i > - 1; i--) { // Check to see if score (combo) is greater than score stored in // array if (combo > scoreboardComboData[i] && i != 0) { // If so continue to next element continue; } // Check to see if score (combo) is less or equal to element 'i' // score && that the element is not the last in the // array, if so the score does not need to be added to the scoreboard else if (combo <= scoreboardComboData[i] && i != scoreboardComboData.Length - 1) { // If the score is lower than element 'i' and greater than the last // element within the array, it needs to be added to the scoreboard. This is achieved // by moving each element under element 'i' down an element. The new score is then inserted // into the array under element 'i' for (int j = totalScores - 1; j > i; j--) { // Name and level data are moved down in their relevant arrays scoreboardTextData[0][j] = scoreboardTextData[0][j - 1]; scoreboardTextData[1][j] = scoreboardTextData[1][j - 1]; // Score (combo) data is moved down in relevant array scoreboardComboData[j] = scoreboardComboData[j - 1]; } // The new Name, level and score (combo) data is inserted into the relevant array under element 'i' scoreboardTextData[0][i + 1] = name; scoreboardTextData[1][i + 1] = level; scoreboardComboData[i + 1] = combo; break; } // If the method gets the this point, it means that the score is greater than all scores within // the array and therefore cannot be added in the above way. As it is not less than any score within // the array. else if (i == 0) { // All Names, levels and scores are moved down within their relevant arrays for (int j = totalScores - 1; j != 0; j--) { scoreboardTextData[0][j] = scoreboardTextData[0][j - 1]; scoreboardTextData[1][j] = scoreboardTextData[1][j - 1]; scoreboardComboData[j] = scoreboardComboData[j - 1]; } // The new number 1 top name, level and score, are added into the first element // within each of their relevant arrays. scoreboardTextData[0][0] = name; scoreboardTextData[1][0] = level; scoreboardComboData[0] = combo; break; } // If the methods get to this point, the combo score is not high enough // to be on the top10 score list and therefore needs to break break; } } // As totalScores < 1, the current score is the first to be added. Therefore no checks need to be made // and the Name, Level and combo data can be entered directly into the first element of their relevant // array. else { scoreboardTextData[0][0] = name; scoreboardTextData[1][0] = level; scoreboardComboData[0] = combo; } } } Example for adding score: private static void Initialize() { scoreboardDoc = new XmlDocument(); if (!File.Exists("Scoreboard.xml")) GenerateXML("Scoreboard.xml"); PopulateScoreBoard("Scoreboard.xml"); // ADD TEST SCORES HERE! AddScore("EXAMPLE", "10", 100); AddScore("EXAMPLE2", "24", 999); PopulateXML("Scoreboard.xml"); } In it's current state the source file is just used for testing, initialize is called within main and PopulateScoreBoard handles the majority of other initialising, so nothing else is needed, except to add a test score. I thank you for your time!

Trying to Understand PLSQL Function

- by Rachel

I am new to PLSQL and I have this huge plsql function which am trying to understand and am having hard time understanding the flow and so I would really appreciate if anyone can run me through the big pieces so that I can understand the flow. Guidance would be highly appreciated.

Problems with with A* algorithm

- by V_Programmer

I'm trying to implement the A* algorithm in Java. I followed this tutorial,in particular, this pseudocode: http://theory.stanford.edu/~amitp/GameProgramming/ImplementationNotes.html The problem is my code doesn't work. It goes into an infinite loop. I really don't know why this happens... I suspect that the problem are in F = G + H function implemented in Graph constructors. I suspect I am not calculate the neighbor F correclty. Here's my code: List<Graph> open; List<Graph> close; private void createRouteAStar(Unit u) { open = new ArrayList<Graph>(); close = new ArrayList<Graph>(); u.ai_route_endX = 11; u.ai_route_endY = 5; List<Graph> neigh; int index; int i; boolean finish = false; Graph current; int cost; Graph start = new Graph(u.xMap, u.yMap, 0, ManhattanDistance(u.xMap, u.yMap, u.ai_route_endX, u.ai_route_endY)); open.add(start); current = start; while(!finish) { index = findLowerF(); current = new Graph(open, index); System.out.println(current.x); System.out.println(current.y); if (current.x == u.ai_route_endX && current.y == u.ai_route_endY) { finish = true; } else { close.add(current); neigh = current.getNeighbors(); for (i = 0; i < neigh.size(); i++) { cost = current.g + ManhattanDistance(current.x, current.y, neigh.get(i).x, neigh.get(i).y); if (open.contains(neigh.get(i)) && cost < neigh.get(i).g) { open.remove(open.indexOf(neigh)); } else if (close.contains(neigh.get(i)) && cost < neigh.get(i).g) { close.remove(close.indexOf(neigh)); } else if (!open.contains(neigh.get(i)) && !close.contains(neigh.get(i))) { neigh.get(i).g = cost; neigh.get(i).f = cost + ManhattanDistance(neigh.get(i).x, neigh.get(i).y, u.ai_route_endX, u.ai_route_endY); neigh.get(i).setParent(current); open.add(neigh.get(i)); } } } } System.out.println("step"); for (i=0; i < close.size(); i++) { if (close.get(i).parent != null) { System.out.println(i); System.out.println(close.get(i).parent.x); System.out.println(close.get(i).parent.y); } } } private int findLowerF() { int i; int min = 10000; int minIndex = -1; for (i=0; i < open.size(); i++) { if (open.get(i).f < min) { min = open.get(i).f; minIndex = i; System.out.println("min"); System.out.println(min); } } return minIndex; } private int ManhattanDistance(int ax, int ay, int bx, int by) { return Math.abs(ax-bx) + Math.abs(ay-by); } And, as I've said. I suspect that the Graph class has the main problem. However I've not been able to detect and fix it. public class Graph { int x, y; int f,g,h; Graph parent; public Graph(int x, int y, int g, int h) { this.x = x; this.y = y; this.g = g; this.h = h; this.f = g + h; } public Graph(List<Graph> list, int index) { this.x = list.get(index).x; this.y = list.get(index).y; this.g = list.get(index).g; this.h = list.get(index).h; this.f = list.get(index).f; this.parent = list.get(index).parent; } public Graph(Graph gp) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = gp.f; } public Graph(Graph gp, Graph parent) { this.x = gp.x; this.y = gp.y; this.g = gp.g; this.h = gp.h; this.f = g + h; this.parent = parent; } public List<Graph> getNeighbors() { List<Graph> aux = new ArrayList<Graph>(); aux.add(new Graph(x+1, y, g,h)); aux.add(new Graph(x-1, y, g,h)); aux.add(new Graph(x, y+1, g,h)); aux.add(new Graph(x, y-1, g,h)); return aux; } public void setParent(Graph g) { parent = g; } } Little Edit: Using the System.out and the Debugger I discovered that the program ALWAYS is check the same "current" graph, (15,8) which is the (u.xMap, u.yMap) position. Looks like it keeps forever in the first step.

Using a mounted NTFS share with nginx

- by Hoff

I have set up a local testing VM with Ubuntu Server 12.04 LTS and the LEMP stack. It's kind of an unconventional setup because instead of having all my PHP scripts on the local machine, I've mounted an NTFS share as the document root because I do my development on Windows. I had everything working perfectly up until this morning, now I keep getting a dreaded 'File not found.' error. I am almost certain this must be somehow permission related, because if I copy my site over to /var/www, nginx and php-fpm have no problems serving my PHP scripts. What I can't figure out is why all of a sudden (after a reboot of the server), no PHP files will be served but instead just the 'File not found.' error. Static files work fine, so I think it's PHP that is causing the headache. Both nginx and php-fpm are configured to run as the user www-data: root@ubuntu-server:~# ps aux | grep 'nginx\|php-fpm' root 1095 0.0 0.0 5816 792 ?

When I examine the error log of nginx, it's filled with a bunch of lines that look like the following: 2012/09/08 11:22:36 [error] 1096#0: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.0.199, server: , request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "192.168.0.123" 2012/09/08 11:22:39 [error] 1096#0: *1 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 192.168.0.199, server: , request: "GET /apc.php HTTP/1.1", upstream: "fastcgi://unix:/var/run/php5-fpm.sock:", host: "192.168.0.123" It's bizarre that this was working previously and now all of sudden PHP is complaining that it can't "find" the scripts on the share. Does anybody know why this is happening? EDIT I tried editing php-fpm.conf and changing chdir to the following: chdir = /mnt/webfiles When I try and restart the php-fpm service, I get the error: Starting php-fpm [08-Sep-2012 14:20:55] ERROR: [pool www] the chdir path '/mnt/webfiles' does not exist or is not a directory This is a total load of bullshit because this directory DOES exist and is mounted! Any ls commands to list that directory work perfectly. Why the hell can't PHP-FPM see this directory?!
