  • Using runtime checking of code contracts in Visual Studio 2010

    - by DigiMortal
    In my last posting about code contracts I introduced how to check input parameters of randomizer using static contracts checking. But you can also compile code contracts to your assemblies and use them also in runtime. In this posting I will show you simple example about runtime checking of code contracts. NB! If you want to play with code and try out things described here feel free to download example solution. if you are speaker and want to use this solution as a part of your sessions then feel free to do so, but don’t forget to refer me and this blog as source of this solution. And please let me know about your session. As a speaker I am very interested about it. :) To see how code contracts are checked at runtime we have to enable runtime checking from project properties. Make sure you have checked the box “Perform Runtime Contract Checking” and make sure you select “Full” from dropdown. These parts are in red box on the screenshot below. Visual Studio 2010 settings for code contracts. Runtime Checking is turned on and checks are made only in public surface. Click on image to see it at original size.  Save project settings. Then compile code and run it. As soon as code execution hits the call to GetRandomFromRangeContracted() exception is thrown. If you are not currently playing with solution referred above take a look at the following screenshot. Visual Studio 2010 runtime checking of code contracts. Exception of type ContractException is thrown when contract is violated. Click on image to see it at original size.  The exact type of exception is ContractException and it is defined in System.Diagnostics.Contracts.__ContractsRuntime namespace. In our example the message of exception is following: "Precondition failed: min < max  Min must be less than max" Besides the description we inserted for the case contract violation the message also contains violated contract type. In this case the type of contract is Precondition. Conclusion Using runtime checking of code contracts enables you to take code contracts with your code and have them checked every time when your methods are called. This way you can assure that all conditions are met to run method or exception is thrown and calling system has to handle the situation.

  • Securing WebSocket applications on Glassfish

    - by Pavel Bucek
    Today we are going to cover deploying secured WebSocket applications on Glassfish and access to these services using WebSocket Client API. WebSocket server application setup Our server endpoint might look as simple as this: @ServerEndpoint("/echo") public class EchoEndpoint { @OnMessage   public String echo(String message) {     return message + " (from your server)";   } } Everything else must be configured on container level. We can start with enabling SSL, which will require web.xml to be added to your project. For starters, it might look as following: <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee">   <security-constraint>     <web-resource-collection>       <web-resource-name>Protected resource</web-resource-name>       <url-pattern>/*</url-pattern>       <http-method>GET</http-method>     </web-resource-collection>     <!-- https -->     <user-data-constraint>       <transport-guarantee>CONFIDENTIAL</transport-guarantee>     </user-data-constraint>   </security-constraint> </web-app> This is minimal web.xml for this task - web-resource-collection just defines URL pattern and HTTP method(s) we want to put a constraint on and user-data-constraint defines that constraint, which is in our case transport-guarantee. More information about these properties and security settings for web application can be found in Oracle Java EE 7 Tutorial. I have some simple webpage attached as well, so I can test my endpoint right away. You can find it (along with complete project) in Tyrus workspace: [webpage] [whole project]. After deploying this application to Glassfish Application Server, you should be able to hit it using your favorite browser. URL where my application resides is https://localhost:8181/sample-echo-https/ (may be different, depends on other configuration). My browser warns me about untrusted certificate (I use what freshly built Glassfish provides - self signed certificates) and after adding an exception for this site, I can see my webpage and I am able to securely connect to wss://localhost:8181/sample-echo-https/echo. WebSocket client Already mentioned demo application also contains test client, but execution of this is skipped for normal build. Reason for this is that Glassfish uses these self-signed "random" untrusted certificates and you are (in most cases) not able to connect to these services without any additional settings. Creating test WebSocket client is actually quite similar to server side, only difference is that you have to somewhere create client container and invoke connect with some additional info. Java API for WebSocket allows you to use annotated and programmatic way to construct endpoints. Server side shows the annotated case, so let's see how the programmatic approach will look. final WebSocketContainer client = ContainerProvider.getWebSocketContainer(); client.connectToServer(new Endpoint() {   @Override   public void onOpen(Session session, EndpointConfig EndpointConfig) {     try {       // register message handler - will just print out the       // received message on standard output.       session.addMessageHandler(new MessageHandler.Whole<String>() {       @Override         public void onMessage(String message) {          System.out.println("### Received: " + message);         }       });       // send a message       session.getBasicRemote().sendText("Do or do not, there is no try.");     } catch (IOException e) {       // do nothing     }   } }, ClientEndpointConfig.Builder.create().build(),    URI.create("wss://localhost:8181/sample-echo-https/echo")); This client should work with some secured endpoint with valid certificated signed by some trusted certificate authority (you can try that with wss://echo.websocket.org). Accessing our Glassfish instance will require some additional settings. You can tell Java which certificated you trust by adding -Djavax.net.ssl.trustStore property (and few others in case you are using linked sample). Complete command line when you are testing your service might need to look somewhat like: mvn clean test -Djavax.net.ssl.trustStore=$AS_MAIN/domains/domain1/config/cacerts.jks\ -Djavax.net.ssl.trustStorePassword=changeit -Dtyrus.test.host=localhost\ -DskipTests=false Where AS_MAIN points to your Glassfish instance. Note: you might need to setup keyStore and trustStore per client instead of per JVM; there is a way how to do it, but it is Tyrus proprietary feature: http://tyrus.java.net/documentation/1.2.1/user-guide.html#d0e1128. And that's it! Now nobody is able to "hear" what you are sending to or receiving from your WebSocket endpoint. There is always room for improvement, so the next step you might want to take is introduce some authentication mechanism (like HTTP Basic or Digest). This topic is more about container configuration so I'm not going to go into details, but there is one thing worth mentioning: to access services which require authorization, you might need to put this additional information to HTTP headers of first (Upgrade) request (there is not (yet) any direct support even for these fundamental mechanisms, user need to register Configurator and add headers in beforeRequest method invocation). I filed related feature request as TYRUS-228; feel free to comment/vote if you need this functionality.

  • Business Strategy - Google Case Study

    Business strategy defined by SMBTN.com is a term used in business planning that implies a careful selection and application of resources to obtain a competitive advantage in anticipation of future events or trends. In more general terms business strategy is positioning a company so that it has the greatest competitive advantage over others in the markets and industries that they participate in. This process involves making corporate decisions regarding which markets to provide goods and services, pricing, acceptable quality levels, and how to interact with others in the marketplace. The primary objective of business strategy is to create and increase value for all of its shareholders and stakeholders through the creation of customer value. According to InformationWeek.com, Google has a distinctive technology advantage over its competitors like Microsoft, eBay, Amazon, Yahoo. Google utilizes custom high-performance systems which are cost efficient because they can scale to extreme workloads. This hardware allows for a huge cost advantage over its competitors. In addition, InformationWeek.com interviewed Stephen Arnold who stated that Google’s programmers are 50%-100% more productive compared to programmers working for their competitors.  He based this theory on Google’s competitors having to spend up to four times as much just to keep up. In addition to Google’s technological advantage, they also have developed a decentralized management schema where employees report directly to multiple managers and team project leaders. This allows for the responsibility of the technology department to be shared amongst multiple senior level engineers and removes the need for a singular department head to oversee the activities of the department.  This is a unique approach from the standard management style. Typically a department head like a CIO or CTO would oversee the department’s global initiatives and business functionality.  This would then be passed down and administered through middle management and implemented by programmers, business analyst, network administrators and Database administrators. It goes without saying that an IT professional’s responsibilities would be directed by Google’s technological advantage and management strategy.  Simply because they work within the department, and would have to design, develop, and support the high-performance systems and would have to report multiple managers and project leaders on a regular basis. Since Google was established and driven by new and immerging technology, all other departments would be directly impacted by the technology department.  In fact, they would have to cater to the technology department since it is a huge driving for in the success of Google.

  • Use CSS Selectors with HtmlUnit

    - by kerry
    HtmlUnit is a great library for performing web integration tests in Java.  But sometimes node traversal can be somewhat cumbersome. Fear not fellow automated tester (good for you!).  I found a great little project on Github that will allow you to query your document for elements via css selectors similar to jQuery. The project is located at https://github.com/chrsan/css-selectors.  You can use Maven to build it, or download 1.0.2 here.  Beware.  I will not be updating this link so I suggest you download the latest code. In any case, you can use it like so: // from HtmlUnit getting started final WebClient webClient = new WebClient(); final HtmlPage page = webClient.getPage("http://htmlunit.sourceforge.net"); final DOMNodeSelector cssSelector = new DOMNodeSelector(page.getDocumentElement()); final Set elements = cssSelector.querySelectorAll("div.section h2"); final Node first = elements.iterator().next(); assertThat(first.getTextContent(), equalTo("HtmlUnit")); The only problem here is that the querySelectAll returns a Set<Node>.  Not HtmlElement like we may want in some cases.   However, if you were to reflect on the Set, you would find that it is indeed a Set of HtmlElement objects. Typically, I like to create a base class for my web tests.  Just for fun, I am using the $ method similar to jQuery. public class WebTestBase { protected WebClient webClient; protected HtmlPage htmlPage; protected void goTo(final String url){ return (HtmlPage)webClient.getPage(url); } protected List $(final String cssSelector) { final DOMNodeSelector cssSelector = new DOMNodeSelector(htmlPage.getDocumentElement()); final Set nodes = cssSelector.querySelectorAll("div.section h2"); // for some reason Set cannot be cast to Set? final List elements = new ArrayList(nodes.size()); for (final Node node : nodes) { elements.add((HtmlElement)node); } return elements; } } Now we can write tests like this: public class LoginWebTest extends WebTestBase { @Test public void login_page_has_instructions() throws Exception { goTo(baseUrl + "/login") assertThat( $("p.instructions").size(), equalTo(1) ); } }

  • Can't load vector font in Nuclex Framework

    - by ProgrammerAtWork
    I've been trying to get this to work for the last 2 hours and I'm not getting what I'm doing wrong... I've added Nuclex.TrueTypeImporter to my references in my content and I've added Nuclex.Fonts & Nuclex.Graphics in my main project. I've put Arial-24-Vector.spritefont & Lindsey.spritefont in the root of my content directory. _spriteFont = Content.Load<SpriteFont>("Lindsey"); // works _testFont = Content.Load<VectorFont>("Arial-24-Vector"); // crashes I get this error on the _testFont line: File contains Microsoft.Xna.Framework.Graphics.SpriteFont but trying to load as Nuclex.Fonts.VectorFont. So I've searched around and by the looks of it it has something to do with the content importer & the content processor. For the content importer I have no new choices, so I leave it as it is, Sprite Font Description - XNA Framework for content processor and I select Vector Font - Nuclex Framework And then I try to run it. _testFont = Content.Load<VectorFont>("Arial-24-Vector"); // crashes again I get the following error Error loading "Arial-24-Vector". It does work if I load a sprite, so it's not a pathing problem. I've checked the samples, they do work, but I think they also use a different version of the XNA framework because in my version the "Content" class starts with a capital letter. I'm at a loss, so I ask here. Edit: Something super weird is going on. I've just added the following two lines to a method inside FreeTypeFontProcessor::FreeTypeFontProcessor( Microsoft::Xna::Framework::Content::Pipeline::Graphics::FontDescription ^fontDescription, FontHinter hinter, just to check if code would even get there: System::Console::WriteLine("I AM HEEREEE"); System::Console::ReadLine(); So, I compile it, put it in my project, I run it and... it works! What the hell?? This is weird because I've downloaded the binaries, they didn't work, I've compiled the binaries myself. didn't work either, but now I make a small change to the code and it works? _. So, now I remove the two lines, compile it again and it works again. Someone care to elaborate what is going on? Probably some weird caching problem!

  • WPF Control Toolkits Comparison for LOB Apps

    In preparation for a new WPF project Ive been researching options for WPF Control toolkits.  While we want a lot of the benefits of WPF, the application is a fairly typical line of business application (LOB).  So were not focused on things like media and animations, but instead a simple, solid, intuitive, and modern user interface that allows for well architected separation of business logic and presentation layers. While WPF is mature, it hasnt lived the long life that Winforms has yet, so there is still a lot of room for third party and community control toolkits to fill the gaps between the controls that ship with the Framework.  There are two such gaps I was concerned about.  As this is an LOB app, we have needs for presenting lots of data and not surprisingly much of it is in grid format with the need for high performance, grouping, inline editing, aggregation, printing and exporting and things that weve been doing with LOB apps for a long time.  In addition we want a dashboard style for the UI in which the user can rearrange and shrink and grow tiles that house the content and functionality.  From a cost perspective, building these types of well performing controls from scratch doesnt make sense.  So I evaluated what you get from the .NET Framework along with a few different options for control toolkits.  I tried to be fairly thorough, but know that this isnt a detailed benchmarking comparison or intense evaluation.  Its just meant to be a feature set comparison to be used when thinking about building an LOB app in WPF.  I tried to list important feature differences and notes based on my experience with the trial versions and what I found in documentation and reference materials and samples.  Ive also listed the importance of the controls based on how I think they are needed in LOB apps.  There are several toolkits available, but given I dont have unlimited time, I picked just a few.  Maybe Ill add on more later.  The toolkits I compared are: Teleriks RadControls for WPF since I had heard some good things about Telerik Infragistics NetAdvantage WPF since both I and the customer have some experience with the vendors tools WPF Toolkit on codeplex since many of my colleagues have used it Blacklight codeplex project which had WPF support for the Tile View control  (with Release 4.3 WPF is not going to be supported in favor of focusing only on SilverLight controls, so I dropped that from the comparison) Click Here to Download the WPF Control Toolkits Comparison Hopefully this helps someone out there.  Feel free to post a comment on your experiences or if you think something I listed is incorrect or missing.  Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • Evaluating Scrum - is it okay to have people with multiple roles in a Scrum team?

    - by Wayne M
    I'm evaluating some Agile-style methodologies for possible introduction to my team. With Scrum, is it allowable to have the same person perform multiple roles? We have a small team of four developers and a web designer; we don't really have a lead (I fulfill this role), QA testers or business analysts, and all of our development tasks come from the CIO. Automated testing is seen as a total waste of time, and everything focuses on speed and not quality. What will happen is the CIO will come up with a development task (whether a feature or a bug) and give it to a developer (not to the whole team, to an individual, often in private or out of the blue) who is then expected to get it completed. The CIO doesn't gather requirements beyond the initial idea (and this has bitten us before as we'll implement something only to find out that none of the end users can use the feature, because they weren't consulted or even informed about it before we developed it, and in a panic we'll be told to revert the change) but requires say in/approval of everything that we do. First things first, is a Scrum style something to consider to introduce some standards and practices? From reading, Scrum seems to rely on a bit more trust and communication and focuses more on project management than on development, which is something we are completely devoid of as we don't have any semblance of project management at present. Second, if it can work is it unreasonable for someone, let's say myself, to act as both ScrumMaster and a developer? Or for a developer to also be the Product Owner (although chances are this will be the CIO, who isn't a developer)? I realize the Scrum Master and the Product Owner should be different people but at the same time I don't think we have anyone who has the qualities of a Product Owner (chances are it would turn into a "I need all these stories, I don't care how but get it done" type of deal and/or any freeze would be unfrozen on a whim). It seems to me that I might need to pick and choose pieces of Scrum/XP/Lean to compensate for how things are done currently, as it's highly unlikely that the mentality can be changed; for instance Pair Programming would never fly (seen as a waste, you get half the tasks done if you need two people for everything), TDD would be a hard sell, but short cycles would be welcomed.

  • How To: Spell Check InfoPath web form in SharePoint 2010

    - by Jeremy Ramos
    Originally posted on: http://geekswithblogs.net/JeremyRamos/archive/2013/11/07/how-to-spell-check-infopath-web-form-in-sharepoint-2010.aspxThis is a sequel to my 2011 post about How To: Spell Check InfoPath Web Form in SharePoint. This time I will share how I managed to achieve Spell Checking in SharePoint 2010. This time round, we have changed our Online Forms strategy to use Custom lists instead of Form Libraries. I thought everything will be smooth sailing as we are using all OOTB features. So, we customised a Custom list form using InfoPath and added a few Rich Text Boxes (Spell Check is a requirement for this specific project). All is good in the InfoPath client including the Spell Checker so, happy days, I published straight away.Here comes the surprises now. I browsed to my Custom List and clicked Add New Item. This launched my Form in a modal dialog format. I went to my Rich Text Boxes to check the spell checker, and voila, it's disabled!I tried hacking the FormServer.aspx and the CustomSpellCheckEntirePage.js again but the new FormServer.aspx behaves differently than of MOSS 2007's. I searched for answers in many blogs to no avail. Often ending up being linked to my old blog post. I also tried placing the spell check javascript into a Content Editor Webpart of the Item's New Form and Edit form. It is launching the Spell Check dialog but it's not spellchecking the page correctly.At this point, I decided I needed to get my project across ASAP so enough with experimentations and logged a ticket with Microsoft Premier Support.On a call with the Support Engineer, I browsed through the Custom List and to the item to demonstrate my problem. Suddenly, the Spell Check tab in the toolbar is now Enabled! Surprised? Not much, it's Microsoft!Anyway, to cut my story short, here is a summary of my solution:Navigate to your Custom ListIn the Ribbon Toolbar, navigate to List > Customize List > Form Web Parts > Content Type Forms > (Item) New Form. This will display the newifs.aspx which is the page displayed when Add New Item is clicked. This page, just like any other SharePoint page, contains webparts. In this case, we have the InfoPath Form Web Part.Add a Content Editor Web Part (CEWP) on top of the InfoPath Form Web Part. (A blank CEWP would do for this example)Navigate to Page and click Stop EditingClick Add New Item again and navigate to a Rich Text box. Tadah! The Spell Check tab is now enabled!Do the same steps for the (Item) Edit Form to enable Spell Checks when editing an item.This "no code" solution discovered purely by accident!

  • viable part-time career in IT/programming?

    - by Rider
    Hi, I'd like to ask for some career advice from you people. Is there a viable job/career that can be done in programming/IT for the long term? Right now, I am thinking about website (PHP?) developer path. My background: I have a degree in computer science and have been a programmer/system analyst for almost 10 years. Lately I took a big break from programming and studied for a B.arch. degree (yes architecture), only to discover that architecture offers zero (0) jobs where I'm from, for 3 years already (and no, I am not going to move and the grass in not greener in other places). I have never been particularly interested in programming, in fact I was bored by it. But I was always quite good at both programming and system analysis, and very valued by practically all my employers. On the other hand, I have never been valued or offered a good job in any other field (although I can do many things, like design, architecture, translations, documentation, teaching, etc etc.) I guess the human component has been always more important for me in programming jobs - I value all the good people I worked with, but not projects. However, I have about zero skills or desire to be a project manager. I also have close to zero skills for selling myself. I like it best when I can do "my thing", have my niche, have an ownership of some project. Right now my career perspective is to do part time programming and to part time teach yoga. I have already started the yoga teaching part. Do you think that part time programming is viable? And what niche works best for that? I have considered web development, QA, or software development in a company like I did before. However, my fear is that when you do programming part-time, you get the most boring coding work, only to see your colleagues move to more interesting projects and up their respective career ladders. I also fear that part-timers are not especially needed either. And, since I don't share much enthusiasm at programming, I'd rather not be around young programmers boiling with geeky enthusiasm about coding, but rather QA mindset with people from different backgrounds and life paths might work better for me. Thanks for any advice, --Rider

  • CAPTCHA blocking for my scraping script?

    - by Surabhil Sergy
    I am working on a scraping project which involves getting web data and parsing them for further use. I have been working using PHP and CURL to make scraping scripts which crawls web data and I make use of either PHP Dom or Simple HTML DOM Parser library for these kinds of projects. On a recent project I encountered some challenges; initially I found the target website blocked my server IP such that the server could not make any successful requests to the site. Understanding these issues as common I bought a set of private proxies and tried to make request calls using them. Though this could get successful response, I noticed the script is getting some kind of blocks after 2-3 continuous requests. On printing and checking the response I could see a pop-up asking for CAPTCHA validation. I could not see any captcha characters to be entered and it also shows an error “input error: invalid referrer”. On examining the source I could see some Google recaptcha scripts within. I’m stuck at this point and I m not able to execute my script. My script is used for gathering data and it needs to go through a large number of pages periodically over the site. But in the current scenario I am not able to proceed with my script. I could see there are some options to overcome these captcha issues and scraping these kinds of sites too are common. I have been checking my script performance and responses over last two months. I could see during first month I was able to execute very large number of requests from a single IP and I was able to get results. Later I get an IP block and used private proxies which could get me some results. Later I am facing now with the captcha trouble. I would appreciate any help or suggestions in this regard. (Often in this kind of questions I used to get a first comment as, ‘Have you asked for prior permission from the target?’ .I haven’t ,but I know there are many sites doing so to get the details out of sites and target sites may not often give access to them. I respect the legality and scraping etiquettes but I would like to know at what point I stuck and how could I overcome that! ) I could provide any supporting information if needed.
