  • Telesharp – An Application Repository for .NET applications

    - by cibrax
    A year ago, we released SO-Aware as our first product in Tellago Studios. SO-Aware represented a new way to manage web services and all the related artifacts like configuration, tests or monitoring data in the Microsoft stack. It was based on the idea of using a lightweight SOA governance approach with a central repository exposed through RESTful services. At that point, we thought the same idea could be extended to enterprise applications in general by providing a generic repository for many of the runtime or design time artifacts generated during the development like configuration, application description or topology (a high level view of the components that made up a system), logging information or binaries. It took us several months to give a form to that idea and implement it as a product, but it is finally here and I am very proud to announce the release today under the name of “TeleSharp”. Telesharp provides in a nutshell the following features, 1. Configure your application topology in a central repository. Application topology in this context means that you can decompose your application and describe it in terms of components and how they interact each other. For example, you can tell that the CRM system is made up of a couple of WCF services and a ASP.NET MVC front end. 2. Centralize configuration for your applications and components.  You can import existing .NET configuration sections into the repository and associate them to the different components. In addition, environment overrides are supported for the configuration sections. We provide tooling and extensions in Visual Studio for managing all the configuration, and a set of powershell commands for automating the configuration deployment. 3. Browse all the assemblies and types remotely in your application servers in a web browser using an interface similar to any of the existing .NET reflection tools. You can easily determine this way whether the server is running the correct version of your applications. 4. Centralize logging and exception management into the repository. You get different reports and a pivot viewer experience for browsing all the different logging information generated by your applications. In addition, TeleSharp provides different providers for pushing the logging information to the central repository using well-known frameworks like ELMAH, Log4Net, EntLib or even Windows ETW.  The central repository itself is implemented as a set of OData services that any application can easily consume using regular Http. You can read more details in this introductory post If you think this product can be a good fit in your organization, you can request a trial version in our Tellago Studios website.

  • Apache - create multiple aliases

    - by mc3mcintyre
    I'm trying to setup two websites on my Apache server. One is www.domain.com and the other is test.domain.com. Currently, my 000-default.conf file reads as follows: <VirtualHost www:80> # The ServerName directive sets the request scheme, hostname and port that # the server uses to identify itself. This is used when creating # redirection URLs. In the context of virtual hosts, the ServerName # specifies what hostname must appear in the request's Host: header to # match this virtual host. For the default virtual host (this file) this # value is not decisive as it is used as a last resort host regardless. # However, you must set it for any further virtual host explicitly. #ServerName www.domain.com #ServerAlias www ServerAdmin [email protected] DocumentRoot /var/www/domain.com/ # Available loglevels: trace8, ..., trace1, debug, info, notice, warn, # error, crit, alert, emerg. # It is also possible to configure the loglevel for particular # modules, e.g. #LogLevel info ssl:warn ErrorLog ${APACHE_LOG_DIR}/domain.error.log CustomLog ${APACHE_LOG_DIR}/domain.access.log combined UseCanonicalName on allow from all Options +Indexes # For most configuration files from conf-available/, which are # enabled or disabled at a global level, it is possible to # include a line for only one particular virtual host. For example the # following line enables the CGI configuration for this host only # after it has been globally disabled with "a2disconf". #Include conf-available/serve-cgi-bin.conf </VirtualHost> <VirtualHost test:80> DocumentRoot "/var/www/domain.com/test/" ServerName test.domain.com ServerAdmin [email protected] ErrorLog ${APACHE_LOG_DIR}/test.domain.error.log CustomLog ${APACHE_LOG_DIR}/test.domain.access.log combined UseCanonicalName on allow from all Options +Indexes </VirtualHost> # vim: syntax=apache ts=4 sw=4 sts=4 sr noet As is, when I use a browser to go to the www location, it show me a directory listing. However, if I remove the www:80 on Line 1 and replace it with *:80, it correctly displays the webpage. I don't understand why. Can anyone help me configure this 000-default.conf file so that www goes to "/var/www/domain.com" and that test goes to "/var/www/domain.com/test"? Thank you.

  • Tomcat Manager Application and HTTP 404 Error

    - by David
    I am trying to set up the admin application for a Tomcat 6.0.24 instance. None of the searches I've done turn up anything I can use. I am using this configuration for Apache 2.2.14: Alias /manager /usr/share/tomcat6-admin/manager <Directory "/usr/share/tomcat6-admin/manager"> Options Indexes FollowSymLinks AllowOverride None allow from all </Directory> ProxyPass /manager ajp://localhost:8009/manager In the tomcat-users.xml I have this: <tomcat-users> <role rolename="tomcat"/> <role rolename="admin"/> <role rolename="operator"/> <role rolename="manager"/> <user username="admin" password="nopasswordforyou" roles="admin,tomcat,manager"/> <user username="operator" password="nevermind" roles="operator"/> </tomcat-users> I found the docs that suggested I needed manager-gui role installed and defined, but that appears to be Tomcat 7, not Tomcat 6. The manager.xml is the default provided with Ubuntu Lucid Lynx 10.04: <Context path="/manager" docBase="/usr/share/tomcat6-admin/manager" antiResourceLocking="false" privileged="true" /> If I access /manager from a web browser, I get a 404 error from Tomcat: "requested resource not available." If I access /manager/images I get the same thing. If I access /manager/401.jsp I get the actual page. In addition, the server.xml has not only the usual Realm (UserDatabaseRealm) but also one for MySQL authentication (JDBCRealm). Investigating this showed that the role of manager was not present there for the user admin; I fixed that by doing: INSERT USER_ROLE_DB SET USER_NAME='admin', ROLE_NAME='manager'; I restarted Tomcat, although I suspect that was overkill. No change. I don't see any errors in catalina.out or in localhost.* log files. What am I missing? What is the interaction between the different realms? How do I get the manager application working?

  • Gauging Maturity of your BPM Strategy - part 1 / 2

    - by Sanjeev Sharma
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} In this post I will discuss the essence of maturity assessment and the business imperative for doing the same in the context of BPM. Social psychology purports that an individual progresses from being a beginner to an expert in a given activity or task along four stages of self-awareness: Unconscious Incompetence where the individual does not understand or know how to do something and does not necessarily recognize the deficit and may even deny the usefulness of the skill. Conscious Incompetence where the individual recognizes the deficit, as well as the value of a new skill in addressing the deficit. Conscious Competence where the individual understands or knows how to do something but demonstrating the skill requires explicit concentration. Unconscious Competence where the individual has had so much practice with a skill that it has become "second nature" and serves as a basis of developing other complementary skills. We can extend the above thinking to an organization as a whole by measuring an organization’s level of competence in a specific area or capability, as an aggregate of the competence levels of individuals it is comprised of. After all organizations too like individuals, evolve through experience, develop “memory” and capabilities that are shaped through a constant cycle of learning, un-learning and re-learning. Hence the key to organizational success lies in developing these capabilities to enable execution of its strategy in-line with the external environment i.e. demand, competition, economy etc. However developing a capability merits establishing a base line in order to Assess the magnitude of improvement from past investments Identify gaps and short-comings Prioritize future investments in the right areas A maturity assessment is essentially an organizational self-awareness check that is aimed at depicting the “as-is” snapshot of an existing capability in-order to guide future investments to develop that capability in-line with business goals. This effectively is the essence of a maturity Organizational capabilities stem through its architecture, routines, culture and intellectual resources that are implicitly and explicitly embedded in its business processes. Given that business processes underpin realization of organizational capabilities, is what has prompted business transformation and process management efforts. Thus, the BPM capability of an organization needs to be measured on an on-going basis to ensure delivery of its planned benefits. In my next post I will describe Oracle’s BPM Maturity assessment methodology.

  • Is anyone doing "real" TDD with Visual-C++, and if yes, how do they do it?

    - by Martin
    Test Driven Development implies writing the test before the code and following a certain cycle: Write Test Check Test (run) Write Production Code Check Test (run) Clean up Production Code Check test (run) As far as I'm concerned, this is only possible if your development solution allows you to very quickly switch between the production and test code, and to execute the test for a certain production code part extremely quickly. Now, while there exist lots of Unit Testing Frameworks for C++ (I'm using Bost.Test atm.) it does seem that there doesn't really exist any decent (for native C++) Visual Studio (Plugin) solution that makes the TDD cycle bearable regardless of framework used. "Bearable" means that it's a one-click action to run a test for a certain cpp file without having to manually set up a separate testing project etc. "Bearable" also means that a simple test starts (linking!) and runs very quickly. So, what tools (plugins) and techniques are out there that make the TDD cycle possible for native C++ development with Visual Studio? Note: I'm fine with free or "commercial" tools. Please: No framework recommendations. (Unless the framework has a dedicated Visual Studio plugin and you want to recommend the plugin.) Edit Note: The answers so far have provided links on how to integrate a Unit Testing framework into Visual Studio. The resources more or less describe how to get the UT framework to compile and get your first Tests running. This is not what this question is about. I'm of the opinion that to really work productively, having the Unit Tests in a manually maintained(!), separate vcproj from your production classes will add so much overhead that TDD "isn't possible". As far as I am aware, you do not add extra "projects" to a Java or C# thing to enable Unit Tests and TDD, and for a good reason. This should be possible with C++ given the right tools, but it seems (this question is about) that there are very little tools for TDD/C++/VS. Googling around, I've found one tool, VisualAssert, that seems to aim in the right direction. However, afaiks, it doesn't seem to be in widespread use (compared to CppUnit, Boost.Test etc.). Edit: I would like to add a comment to the context for this question. I think it does a good summary of outlining (part of) the problem: (comment by Billy ONeal) Visual Studio does not use "build scripts" that are reasonably editable by the user. One project produces one binary. Moreover, Java has the property that Java never builds a complete binary -- the binary you build is just a ZIP of the class files. Therefore it's possible to compile separately then JAR together manually (using e.g. 7z). C++ and C# both actually link their binaries, so generally speaking you can't write a script like that. The closest you can get is to compile everything separately and then do two linkings (one for production, one for testing).

  • JS closures - Passing a function to a child, how should the shared object be accessed

    - by slicedtoad
    I have a design and am wondering what the appropriate way to access variables is. I'll demonstrate with this example since I can't seem to describe it better than the title. Term is an object representing a bunch of time data (a repeating duration of time defined by a bunch of attributes) Term has some print functionality but does not implement the print functions itself, rather they are passed in as anonymous functions by the parent. This would be similar to how shaders can be passed to a renderer rather than defined by the renderer. A container (let's call it Box) has a Schedule object that can understand and use Term objects. Box creates Term objects and passes them to Schedule as required. Box also defines the print functions stored in Term. A print function usually takes an argument and uses it to return a string based on that argument and Term's internal data. Sometime the print function could also use data stored in Schedule, though. I'm calling this data shared. So, the question is, what is the best way to access this shared data. I have a lot of options since JS has closures and I'm not familiar enough to know if I should be using them or avoiding them in this case. Options: Create a local "reference" (term used lightly) to the shared data (data is not a primitive) when defining the print function by accessing the shared data through Schedule from Box. Example: var schedule = function(){ var sched = Schedule(); var t1 = Term( function(x){ // Term.print() return (x + sched.data).format(); }); }; Bind it to Term explicitly. (Pass it in Term's constructor or something). Or bind it in Sched after Box passes it. And then access it as an attribute of Term. Pass it in at the same time x is passed to the print function, (from sched). This is the most familiar way for my but it doesn't feel right given JS's closure ability. Do something weird like bind some context and arguments to print. I'm hoping the correct answer isn't purely subjective. If it is, then I guess the answer is just "do whatever works". But I feel like there are some significant differences between the approaches that could have a large impact when stretched beyond my small example.

  • Correct use of VAO's in OpenGL ES2 for iOS?

    - by sak
    I'm migrating to OpenGL ES2 for one of my iOS projects, and I'm having trouble to get any geometry to render successfully. Here's where I'm setting up the VAO rendering: void bindVAO(int vertexCount, struct Vertex* vertexData, GLushort* indexData, GLuint* vaoId, GLuint* indexId){ //generate the VAO & bind glGenVertexArraysOES(1, vaoId); glBindVertexArrayOES(*vaoId); GLuint positionBufferId; //generate the VBO & bind glGenBuffers(1, &positionBufferId); glBindBuffer(GL_ARRAY_BUFFER, positionBufferId); //populate the buffer data glBufferData(GL_ARRAY_BUFFER, vertexCount, vertexData, GL_STATIC_DRAW); //size of verte position GLsizei posTypeSize = sizeof(kPositionVertexType); glVertexAttribPointer(kVertexPositionAttributeLocation, kVertexSize, kPositionVertexTypeEnum, GL_FALSE, sizeof(struct Vertex), (void*)offsetof(struct Vertex, position)); glEnableVertexAttribArray(kVertexPositionAttributeLocation); //create & bind index information glGenBuffers(1, indexId); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, *indexId); glBufferData(GL_ELEMENT_ARRAY_BUFFER, vertexCount, indexData, GL_STATIC_DRAW); //restore default state glBindVertexArrayOES(0); glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, 0); glBindBuffer(GL_ARRAY_BUFFER, 0); } And here's the rendering step: //bind the frame buffer for drawing glBindFramebuffer(GL_FRAMEBUFFER, outputFrameBuffer); glClear(GL_COLOR_BUFFER_BIT); //use the shader program glUseProgram(program); glClearColor(0.4, 0.5, 0.6, 0.5); float aspect = fabsf(320.0 / 480.0); GLKMatrix4 projectionMatrix = GLKMatrix4MakePerspective(GLKMathDegreesToRadians(65.0f), aspect, 0.1f, 100.0f); GLKMatrix4 modelViewMatrix = GLKMatrix4MakeTranslation(0.0f, 0.0f, -1.0f); GLKMatrix4 mvpMatrix = GLKMatrix4Multiply(projectionMatrix, modelViewMatrix); //glUniformMatrix4fv(projectionMatrixUniformLocation, 1, GL_FALSE, projectionMatrix.m); glUniformMatrix4fv(modelViewMatrixUniformLocation, 1, GL_FALSE, mvpMatrix.m); glBindVertexArrayOES(vaoId); glDrawElements(GL_TRIANGLE_FAN, kVertexCount, GL_FLOAT, &indexId); //bind the color buffer glBindRenderbuffer(GL_RENDERBUFFER, colorRenderBuffer); [context presentRenderbuffer:GL_RENDERBUFFER]; The screen is rendering the color passed to glClearColor correctly, but not the shape passed into bindVAO. Is my VAO being built correctly? Thanks!

  • How Big Data and Social Won the Election

    - by Mike Stiles
    The story of big data’s influence on the outcome of the US Presidential election is worth a good look, because a) it’s a harbinger of things to come, and b) it’s an example of similar successes available to any enterprise seriously resourcing integrated big data, modeling, and data-driven execution on all assets, including social. Obama campaign manager Jim Messina fielded a data and analytics brain trust 5 times larger than 2008. At that time, there were numerous databases from various sources, few of them talking to each other. This time, the mission was to be metrics-centered and measure everything measurable, and in context with all the other data. Big data showed them exactly what they needed to know and told them what to do about it. It showed them women 40-49 on the west coast would donate big money if they got to eat with George Clooney. Women on the east coast would pony up to hang out with Sarah Jessica Parker. Extensive daily modeling showed them what kinds of email appeals, from who, and to whom, would prove most successful in raising cash, recruiting volunteers, and getting out the vote. Swing state voters were profiled and approached with more customized targeting that at any time in history. Ads were purchased on specific shows watched by the targets, increasing efficiency 14% over traditional media buys. For all the criticism of the candidate’s focus on appearing on comedy and entertainment shows, and local radio morning shows, that’s where the data sent them to reach the voters most likely to turn out for them. And then there was social. Again, more than in any other election, Facebook was used for virtual, highly efficient door-to-door canvasing. Facebook fans got pictures of friends in swing states and were asked to encourage them to act. Using that approach, 1 in 5 peer-to-peer appeals led to the desired action. Assumptions, gut, intuition, campaign experience, all took a backseat to strategy shifts solidly backed up by data. Zeroing in on demographics likely to back the President and tracking their mood daily literally changed the voter landscape. The Romney team watched Obama voters appear seemingly out of thin air. One Obama campaign aide said, “We ran the election 66,000 times every night.” Which brings us to your organization. If you’re starting to feel like the battle-cry of “but this is the way we’ve always done it” is starting to put you in an extremely vulnerable position, you’re right. Social has become a key communication tool of the 21st century. Failing to use it, or failing to invest in a deep understanding of who your customers and prospects are so the content you post there will achieve desired actions and results, will leave you waking up one morning wondering, “What happened?”@mikestilesPhoto stock.xchng

  • Which is the most practical way to add functionality to this piece of code?

    - by Adam Arold
    I'm writing an open source library which handles hexagonal grids. It mainly revolves around the HexagonalGrid and the Hexagon class. There is a HexagonalGridBuilder class which builds the grid which contains Hexagon objects. What I'm trying to achieve is to enable the user to add arbitrary data to each Hexagon. The interface looks like this: public interface Hexagon extends Serializable { // ... other methods not important in this context <T> void setSatelliteData(T data); <T> T getSatelliteData(); } So far so good. I'm writing another class however named HexagonalGridCalculator which adds some fancy pieces of computation to the library like calculating the shortest path between two Hexagons or calculating the line of sight around a Hexagon. My problem is that for those I need the user to supply some data for the Hexagon objects like the cost of passing through a Hexagon, or a boolean flag indicating whether the object is transparent/passable or not. My question is how should I implement this? My first idea was to write an interface like this: public interface HexagonData { void setTransparent(boolean isTransparent); void setPassable(boolean isPassable); void setPassageCost(int cost); } and make the user implement it but then it came to my mind that if I add any other functionality later all code will break for those who are using the old interface. So my next idea is to add annotations like @PassageCost, @IsTransparent and @IsPassable which can be added to fields and when I'm doing the computation I can look for the annotations in the satelliteData supplied by the user. This looks flexible enough if I take into account the possibility of later changes but it uses reflection. I have no benchmark of the costs of using annotations so I'm a bit in the dark here. I think that in 90-95% of the cases the efficiency is not important since most users wont't use a grid where this is significant but I can imagine someone trying to create a grid with a size of 5.000.000.000 X 5.000.000.000. So which path should I start walking on? Or are there some better alternatives? Note: These ideas are not implemented yet so I did not pay too much attention to good names.

Type “speed” into the quick find bar and look for the Speed Dial State entry. Change the 1 to 2 and click save. You will see the following message concerning the changes…click OK. Next type “search” into the quick find bar and look for the Speed Dial Search Type entry. Remove all of the text in the blank and click save. Once again you will see a message about the latest change that you have made. At this point you may need to restart Opera for both changes to take full effect. There will be a noticeable difference in how the Speed Dial page looks afterwards and is much cleaner without the Search bar and text field. You will also still be able to access the right click context menu just like before. Conclusion If you have been looking to get a cleaner and less cluttered Speed Dial page in Opera, then these two little hacks will get the job done!

  • Power Your Cloud with Oracle Fusion Middleware

    - by user753488
    Introducing the biggest and most strategic event for Fusion Middleware this year: Power your Cloud with Oracle Fusion Middleware. Running in over 50 cities across the globe, this event is aimed at Architects, IT Managers, and technical leaders like you who are using Fusion Middleware or trying to learn more about middleware in the context of Cloud computing. Join us for a special kickoff on Wednesday, June 29th in Chicago for the first event in North America. This event features an exclusive keynote from Rick Schultz, VP of Technology Product Marketing. Cloud is certainly all the rage. But what can we make of it? According to Alex Andrianopoulos, Vice President Product Marketing for Fusion Middleware states, “Not since Java was unveiled have we seen something so transformative hit the industry. The promised benefits of Cloud are many, significant, and deliver value to both IT organizations as well as the Line of Business. The benefits range from lower data center costs, to significantly reduced environmental impact, to the ability to capture more of the opportunities that market present through increased agility in resource deployment and dramatically reduced time to market.” With an ROI so promising, why isn’t everyone on Cloud already? It’s a question a lot of IT managers are struggling with. While the promised benefits of Cloud computing can be immense, achieving them requires much more than the adoption of a new architecture, or the virtualization of servers, or the outsourcing of some or all of the IT resources. These may be useful steps towards moving to a Cloud computing blueprint, but on their own do not deliver Cloud computing and its associated benefits to the enterprise. This is exactly what we’ll be addressing in the event series, ways you can leverage Complete, Open and Integrated capabilities of Oracle Fusion Middleware today to get one step closer to Cloud. Whether you’re: Leveraging Exalogic Elastic Cloud to consolidate your applications Improving agility with Oracle SOA to generate a foundation for shared data services Securing and managing your Cloud using Oracle Identity Management and Oracle Enterprise Manager Migrating from mainframe to Cloud using Oracle Tuxedo, Coherence and GoldenGate Building applications in the Cloud swiftly and easier with Oracle’s WebCenter Suite Join us for the first of its kind event in Chicago this week by registering now, or find an event near you.

  • Reporting on common code smells : A POC

    - by Dave Ballantyne
    Over the past few blog entries, I’ve been looking at parsing TSQL scripts in a variety of ways for a variety of tasks.  In my last entry ‘How to prevent ‘Select *’ : The elegant way’, I looked at parsing SQL to report upon uses of SELECT *.  The obvious question leading on from this is, “Great, what about other code smells ?”  Well, using the language service parser to do that was turning out to be a bit of a hard job,  sure I was getting tokens but no real context.  I wasn't even being told when an end of statement had been reached. One of the other parsing options available from Microsoft is exposed in the assembly ‘Microsoft.SqlServer.TransactSql.ScriptDom’,  this is ,I believe, installed with the client development tools with SQLServer.  It is much more feature rich than the original parser I had used and breaks a TSQL script into intuitive classes for analysis. So, what sort of smells can I now find using it ?  Well, for an opening gambit quite a nice little list. Use of NOLOCK Set of READ UNCOMMITTED Use of SELECT * Insert without column references Explicit datatype conversion on Sargs Cross server selects Non use of two-part naming convention Table and Query hint usage Changes in set options Use of single line comments Use of ordinal column positions in ORDER BY clause Now, lets not argue the point that “It depends” as smells on some of these, but as an academic exercise it is quite interesting.  The code is available from this link :https://www.dropbox.com/s/rfk32sou4fzl2cw/TSQLDomTest.zip  All the usual disclaimers apply to this code, I cannot be held responsible for anything ranging from mild annoyance through to universe destruction due to the use of this code or examples. The zip file contains a powershell script and my test cases.  The assembly used requires .Net 4 to run, which means that you will need powershell 3 ( though im running through PowerGUI and all works ok ) .  The code searches for all .sql files in the folder hierarchy for the workingpath,  you can override this if you want by simply changing the $Folder variable, and processes each in turn for the smells.  Feedback is not great at the moment, all it does is output to an xml file (Smells.xml) the offset position and a description of the smell found. Right now, I am interested in your feedback.  What do you think ?  Is this (or should it be) more than an academic exercise ?  Can tooling such as this be used as some form of code quality measure ?  Does it Work ? Do you have a case listed above which is not being reported ? Do you have a case that you would love to be reported ? Let me know , please mailto: [email protected]. Thanks

  • We've completed the first iteration

    - by CliveT
    There are a lot of features in C# that are implemented by the compiler and not by the underlying platform. One such feature is a lambda expression. Since local variables cannot be accessed once the current method activation finishes, the compiler has to go out of its way to generate a new class which acts as a home for any variable whose lifetime needs to be extended past the activation of the procedure. Take the following example:     Random generator = new Random();     Func func = () = generator.Next(10); In this case, the compiler generates a new class called c_DisplayClass1 which is marked with the CompilerGenerated attribute. [CompilerGenerated] private sealed class c__DisplayClass1 {     // Fields     public Random generator;     // Methods     public int b__0()     {         return this.generator.Next(10);     } } Two quick comments on this: (i)    A display was the means that compilers for languages like Algol recorded the various lexical contours of the nested procedure activations on the stack. I imagine that this is what has led to the name. (ii)    It is a shame that the same attribute is used to mark all compiler generated classes as it makes it hard to figure out what they are being used for. Indeed, you could imagine optimisations that the runtime could perform if it knew that classes corresponded to certain high level concepts. We can see that the local variable generator has been turned into a field in the class, and the body of the lambda expression has been turned into a method of the new class. The code that builds the Func object simply constructs an instance of this class and initialises the fields to their initial values.     c__DisplayClass1 class2 = new c__DisplayClass1();     class2.generator = new Random();     Func func = new Func(class2.b__0); Reflector already contains code to spot this pattern of code and reproduce the form containing the lambda expression, so this is example is correctly decompiled. The use of compiler generated code is even more spectacular in the case of iterators. C# introduced the idea of a method that could automatically store its state between calls, so that it can pick up where it left off. The code can express the logical flow with yield return and yield break denoting places where the method should return a particular value and be prepared to resume.         {             yield return 1;             yield return 2;             yield return 3;         } Of course, there was already a .NET pattern for expressing the idea of returning a sequence of values with the computation proceeding lazily (in the sense that the work for the next value is executed on demand). This is expressed by the IEnumerable interface with its Current property for fetching the current value and the MoveNext method for forcing the computation of the next value. The sequence is terminated when this method returns false. The C# compiler links these two ideas together so that an IEnumerator returning method using the yield keyword causes the compiler to produce the implementation of an Iterator. Take the following piece of code.         IEnumerable GetItems()         {             yield return 1;             yield return 2;             yield return 3;         } The compiler implements this by defining a new class that implements a state machine. This has an integer state that records which yield point we should go to if we are resumed. It also has a field that records the Current value of the enumerator and a field for recording the thread. This latter value is used for optimising the creation of iterator instances. [CompilerGenerated] private sealed class d__0 : IEnumerable, IEnumerable, IEnumerator, IEnumerator, IDisposable {     // Fields     private int 1__state;     private int 2__current;     public Program 4__this;     private int l__initialThreadId; The body gets converted into the code to construct and initialize this new class. private IEnumerable GetItems() {     d__0 d__ = new d__0(-2);     d__.4__this = this;     return d__; } When the class is constructed we set the state, which was passed through as -2 and the current thread. public d__0(int 1__state) {     this.1__state = 1__state;     this.l__initialThreadId = Thread.CurrentThread.ManagedThreadId; } The state needs to be set to 0 to represent a valid enumerator and this is done in the GetEnumerator method which optimises for the usual case where the returned enumerator is only used once. IEnumerator IEnumerable.GetEnumerator() {     if ((Thread.CurrentThread.ManagedThreadId == this.l__initialThreadId)               && (this.1__state == -2))     {         this.1__state = 0;         return this;     } The state machine itself is implemented inside the MoveNext method. private bool MoveNext() {     switch (this.1__state)     {         case 0:             this.1__state = -1;             this.2__current = 1;             this.1__state = 1;             return true;         case 1:             this.1__state = -1;             this.2__current = 2;             this.1__state = 2;             return true;         case 2:             this.1__state = -1;             this.2__current = 3;             this.1__state = 3;             return true;         case 3:             this.1__state = -1;             break;     }     return false; } At each stage, the current value of the state is used to determine how far we got, and then we generate the next value which we return after recording the next state. Finally we return false from the MoveNext to signify the end of the sequence. Of course, that example was really simple. The original method body didn't have any local variables. Any local variables need to live between the calls to MoveNext and so they need to be transformed into fields in much the same way that we did in the case of the lambda expression. More complicated MoveNext methods are required to deal with resources that need to be disposed when the iterator finishes, and sometimes the compiler uses a temporary variable to hold the return value. Why all of this explanation? We've implemented the de-compilation of iterators in the current EAP version of Reflector (7). This contrasts with previous version where all you could do was look at the MoveNext method and try to figure out the control flow. There's a fair amount of things we have to do. We have to spot the use of a CompilerGenerated class which implements the Enumerator pattern. We need to go to the class and figure out the fields corresponding to the local variables. We then need to go to the MoveNext method and try to break it into the various possible states and spot the state transitions. We can then take these pieces and put them back together into an object model that uses yield return to show the transition points. After that Reflector can carry on optimising using its usual optimisations. The pattern matching is currently a little too sensitive to changes in the code generation, and we only do a limited analysis of the MoveNext method to determine use of the compiler generated fields. In some ways, it is a pity that iterators are compiled away and there is no metadata that reflects the original intent. Without it, we are always going to dependent on our knowledge of the compiler's implementation. For example, we have noticed that the Async CTP changes the way that iterators are code generated, so we'll have to do some more work to support that. However, with that warning in place, we seem to do a reasonable job of decompiling the iterators that are built into the framework. Hopefully, the EAP will give us a chance to find examples where we don't spot the pattern correctly or regenerate the wrong code, and we can improve things. Please give it a go, and report any problems.

  • Is Cygwin or Windows Command Prompt preferable for getting a consistent terminal experience for development?

    - by Paul Hazen
    The question: Which is better, installing cygwin or one of its cousins on all my windows machines to have a consistent terminal experience across all my development machines, or becoming well trained in the skill of mentally switching from linux terminal to windows command prompt? Systems I use: OSX Lion on a Macbook Air Windows 8 on a desktop Windows 7 on the same desktop Fedora 16 on the same desktop What I'm trying to accomplish Configure an entirely consistent (or consistent enough) terminal experience across all my machines. "enough" in this context is clearly subjective. Please be clear in your answer why the configuration you suggest is consistent enough. One more thing to keep in mind: While I do write a lot of code intended to run on Windows (actually code that runs on Windows Phone which necessitates a windows machine), I also write a lot of Java code, and prefer to do so in vim. I test a local repo in Java on my windows machine, and push to another test machine running ubuntu later in the development stage. When I push to the ubuntu machine, I'm exclusively in terminal, since I'm accessing it via SSH. Summary, with more accurate question: Is there a good way to accomplish what I'm trying to do, or is it better to get accustomed to remembering different commands based on the system I'm on? Which (if either) is considered "best practice" by the development community? Alternatively, for a consistent development experience, would it be better to write all my code SSHed into another machine, and move things to windows for compile / build only when I needed to? That seems like too much work... but could be a solution. Update: While there are insightful responses below, I have yet to hear an answer that talks about why any given solution is superior. Cygwin/GnuWin32 is certainly a way to accomplish a similar experience on all platforms, but since I'm just learning all things command line, I don't want to set myself up to do a lot of relearning/unlearning in the future. Cygwin/GnuWin32 has its peculiarities I would imagine, and being aware of how that set up works on Windows is a learning curve. Additionally, using Cygwin/GnuWin32 robs me of learning the benefits of PowerShell. As a newcomer to working in a command line, which path should I choose to minimize having to relearn/unlearn things in the future? or as my first paragraph poses: [is it better to use Cygwin] ...or [become] well trained in the skill of mentally switching from linux terminal to windows command prompt?

  • A brief note for customers running SOA Suite on AIX platforms

    - by christian
    When running Oracle SOA Suite with IBM JVMs on the AIX platform, we have seen performance slowdowns and/or memory leaks. On occasion, we have even encountered some OutOfMemoryError conditions and the concomittant Java coredump. If you are experiencing this issue, the resolution may be to configure -Dsun.reflect.inflationThreshold=0 in your JVM startup parameters. https://www.ibm.com/developerworks/java/library/j-nativememory-aix/ contains a detailed discussion of the IBM AIX JVM memory model, but I will summarize my interpretation and understanding of it in the context of SOA Suite, below. Java ClassLoaders on IBM JVMs are allocated a native memory area into which they are anticipated to map such things as jars loaded from the filesystem. This is an excellent memory optimization, as the file can be loaded into memory once and then shared amongst many JVMs on the same host, allowing for excellent horizontal scalability on AIX hosts. However, Java ClassLoaders are not used exclusively for loading files from disk. A performance optimization by the Oracle Java language developers enables reflectively accessed data to optimize from a JNI call into Java bytecodes which are then amenable to hotspot optimizations, amongst other things. This performance optimization is called inflation, and it is executed by generating a sun.reflect.DelegatingClassLoader instance dynamically to inject the Java bytecode into the virtual machine. It is generally considered an excellent optimization. However, it interacts very negatively with the native memory area allocated by the IBM JVM, effectively locking out memory that could otherwise be used by the Java process. SOA Suite and WebLogic are both very large users of reflection code. They reflectively use many code paths in their operation, generating lots of DelegatingClassLoaders in normal operation. The IBM JVM slowdown and subsequent OutOfMemoryError are as a direct result of the Java memory consumed by the DelegatingClassLoader instances generated by SOA Suite and WebLogic. Java garbage collection runs more frequently to try and keep memory available, until it can no longer do so and throws OutOfMemoryError. The setting sun.reflect.inflationThreshold=0 disables this optimization entirely, never allowing the JVM to generate the optimized reflection code. IBM JVMs are susceptible to this issue primarily because all Java ClassLoaders have this native memory allocation, which is shared with the regular Java heap. Oracle JVMs don't automatically give all ClassLoaders a native memory area, and my understanding is that jar files are never mapped completely from shared memory in the same way as IBM does it. This results in different behaviour characteristics on IBM vs Oracle JVMs.

  • What are the drawbacks of sending XML to browsers and let them apply XSLT?

    - by MainMa
    Context Working as a freelance developer, I often made websites completely based on XSLT. In other words, on every request, an XML file is generated, containing everything we need to know about the page content: the name of the user currently logged in, the top menu entries, if this menu is dynamic/configurable, the text to display in a specific area of the page, etc. Then XSL process (caches, etc.) it to HTML/XHTML page to send to the browser. It has a good point to make it easier to create small-scale websites, especially with PHP. It is a sort of template engine, but which I prefer to other template engines because it's much more powerful than most of template engines, and because I know it better and like it. It is also possible, when need, to give an access to raw XML data on demand for an automated access, without the need to create separate APIs. Of course, it will fail completely on any medium-scale or large-scale website, since, even with good caching techniques, XSL still degrades overall website performance and requires more CPU serverside. Question Modern browsers have the ability to take an XML file and to transform it with an associated XSL file declared in XML like <?xml-stylesheet href="demo.xslt" type="text/xsl"?>. Firefox 3 can do it. Internet Explorer 8 can do it too. It means that it is possible to migrate XSL processing from the server to the client side for 50% of users (according on browser statistics on several websites where I may want to implement this). It means that those 50% of users will receive only the XML file at each request, thus reducing their and server's bandwidth (XML file being much shorter than its processed HTML analog), and reducing server's CPU usage. What are the drawbacks of this technique? I thought about several ones, but it doesn't apply in this situation: Difficult implementation and the need to choose, based on the browser request, when to send raw XML and when to transform it to HTML instead. Obviously, the system will not be much more difficult then the actual one. The only change to make is to add XSL file link to every XML, and to add a browser check. More IO and bandwidth usage, since the XSLT file will be downloaded by the browsers, instead of being cached by the server. I don't think it will be a problem, since XSLT file will be cached by the browsers (like images, or CSS, or JavaScript files are cached actually). Possibly some problems on client side, like maybe problems when saving a page in some browsers. Difficulty to debug code: it is impossible to obtain an HTML source the browser is actually using, since the only displayed source is the downloaded XML. On the other hand, I rarely go look at HTML code on client side, and in most cases, it is unusable directly (whitespace being removed).

  • Why is Double.Parse so slow?

    - by alexhildyard
    I was recently investigating a bottleneck in one of my applications, which read a CSV file from disk using a TextReader a line at a time, split the tokens, called Double.Parse on each one, then shunted the results into an object list. I was surprised to find it was actually the Double.Parse which seemed to be taking up most of the time.Googling turned up this, which is a little unfocused in places but throws out some excellent ideas:It makes more sense to work with binary format directly, rather than coerce strings into doublesThere is a significant performance improvement in composing doubles directly from the byte stream via long intermediariesString.Split is inefficient on fixed length recordsIn fact it turned out that my problem was more insidious and also more mundane -- a simple case of bad data in, bad data out. Since I had been serialising my Doubles as strings, when I inadvertently divided by zero and produced a "NaN", this of course was serialised as well without error. And because I was reading in using Double.Parse, these "NaN" fields were also (correctly) populating real Double objects without error. The issue is that Double.Parse("NaN") is incredibly slow. In fact, it is of the order of 2000x slower than parsing a valid double. For example, the code below gave me results of 357ms to parse 1000 NaNs, versus 15ms to parse 100,000 valid doubles.            const int invalid_iterations = 1000;            const int valid_iterations = invalid_iterations * 100;            const string invalid_string = "NaN";            const string valid_string = "3.14159265";            DateTime start = DateTime.Now;                        for (int i = 0; i < invalid_iterations; i++)            {                double invalid_double = Double.Parse(invalid_string);            }            Console.WriteLine(String.Format("{0} iterations of invalid double, time taken (ms): {1}",                invalid_iterations,                ((TimeSpan)DateTime.Now.Subtract(start)).Milliseconds            ));            start = DateTime.Now;            for (int i = 0; i < valid_iterations; i++)            {                double valid_double = Double.Parse(valid_string);            }            Console.WriteLine(String.Format("{0} iterations of valid double, time taken (ms): {1}",                valid_iterations,                ((TimeSpan)DateTime.Now.Subtract(start)).Milliseconds            )); I think the moral is to look at the context -- specifically the data -- as well as the code itself. Once I had corrected my data, the performance of Double.Parse was perfectly acceptable, and while clearly it could have been improved, it was now sufficient to my needs.

  • System freezes while not in use, how do I fix this?

    - by PHLAK
    Bare with me, the following is a bit winded. I have Ubuntu 10.10 Desktop 64-bit installed on my laptop and up until a few weeks ago it has been running great. Then one day, while I was not using the laptop it froze. I was logged in as my user but had locked the screen locked and closed the lid. I didn't notice that it had frozen until I opened the lid and wiggled the mouse to try and log in. The screen remained black and I got no response. I immediately tried Alt + F2, F3, F4, etc. but got no response. The only thing I could do was hold the power button to power off the machine. The freezing has happened as quickly as within 10-20 minutes of the system being logged off and lid closed and as long as 4-6 hours. My machine is NOT configured to go into standby when plugged in and this has happened both on AC power and battery. Troubleshooting I have performed: I uninstalled programs I knew that I had installed between when it was working fine and having problems. Those programs were CrashPlan, Shutter and Conky. After uninstalling ALL of these programs the freezing still occurs. Next, I decided to SSH into the machine from my desktop and leave an htop and tail of the syslog running. Here are screenshots of the last thing shown on both when the system froze: htop, syslog Here is a dump of my syslog after another freeze. The freeze happened at 9:14 and I didn't notice it until about 10 minutes later and rebooted, hence the 10 minute gap from 9:14 to 9:24. In the above syslog dump I noticed a lot of NVRM: os_raise_smp_barrier(), invalid context! and upon investigating that message learned it was from the proprietary Nvidia driver I had installed. Thinking this could be part of the problem I uninstalled the Nvidia driver and reverted to using the Nouveau driver. The computer still froze after a few hours. Lastly, thinking the problem could be caused by overheating I used compressed air to blow out any dust in the CPU vents and all other openings on the laptop. None of the above troubleshooting has helped and the freezing still occurs. What other steps can I take to troubleshoot and/or fix this problem? Note: Yesterday X started to eat up a lot of CPU power and eventually froze my system while I was forwarding an X session over SSH (from another PC to my laptop). I'm unsure if this is related or not as it doesn't match any of the symptoms of the problem above. Aside from this, the system has never frozen while in use, even under heavy load. EDIT: I just ran Memtest86+ and it made it through two passes without any errors. Just eliminating possible causes here.

  • Why won't my vertex buffer render in GLFW3?

    - by sm81095
    I have started to try to learn OpenGL, and I decided to use GLFW to assist in window creation. The problem is, since GLFW3 is so new, there are no tutorials on it or how to use it with modern OpenGL (3.3, specifically). Using the GLFW3 tutorial found on the website, which uses older OpenGL rendering (glBegin(GL_TRIANGLES), glVertex3f(), and such), I can get a triangle to render to the screen. The problem is, using new OpenGL, I can't get the same triangle to render to the screen. I am new to OpenGL, and GLFW3 is new to most people, so I may be completely missing something obvious, but here is my code: static const GLuint g_vertex_buffer_data[] = { -1.0f, -1.0f, 0.0f, 1.0f, -1.0f, 0.0f, 0.0f, 1.0f, 0.0f }; int main(void) { GLFWwindow* window; if(!glfwInit()) { fprintf(stderr, "Failed to initialize GLFW."); return -1; } glfwWindowHint(GLFW_SAMPLES, 4); glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3); glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3); glfwWindowHint(GLFW_OPENGL_FORWARD_COMPAT, GL_TRUE); glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE); window = glfwCreateWindow(800, 600, "Test Window", NULL, NULL); if(!window) { glfwTerminate(); fprintf(stderr, "Failed to create a GLFW window"); return -1; } glfwMakeContextCurrent(window); glewExperimental = GL_TRUE; GLenum err = glewInit(); if(err != GLEW_OK) { glfwTerminate(); fprintf(stderr, "Failed to initialize GLEW"); fprintf(stderr, (char*)glewGetErrorString(err)); return -1; } GLuint VertexArrayID; glGenVertexArrays(1, &VertexArrayID); glBindVertexArray(VertexArrayID); GLuint programID = LoadShaders("SimpleVertexShader.glsl", "SimpleFragmentShader.glsl"); GLuint vertexBuffer; glGenBuffers(1, &vertexBuffer); glBindBuffer(GL_ARRAY_BUFFER, vertexBuffer); glBufferData(GL_ARRAY_BUFFER, sizeof(g_vertex_buffer_data), g_vertex_buffer_data, GL_STATIC_DRAW); while(!glfwWindowShouldClose(window)) { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); glUseProgram(programID); glEnableVertexAttribArray(0); glBindBuffer(GL_ARRAY_BUFFER, vertexBuffer); glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 0, (void*)0); glDrawArrays(GL_TRIANGLES, 0, 3); glDisableVertexAttribArray(0); glfwSwapBuffers(window); glfwPollEvents(); } glDeleteBuffers(1, &vertexBuffer); glDeleteProgram(programID); glfwDestroyWindow(window); glfwTerminate(); exit(EXIT_SUCCESS); } I know it is not my shaders, they are super simple and I've checked them against GLFW 2.7 so I know that they work. I'm assuming that I've missed something crucial to using the OpenGL context with GLFW3, so any help locating the problem would be greatly appreciated.

  • C# Dev - I've tried Lisps, but I don't get it.

    - by Jonathan Mitchem
    After a few months of learning about and playing with lisps, both CL and a bit of Clojure, I'm still not seeing a compelling reason to write anything in it instead of C#. I would really like some compelling reasons, or for someone to point out that I'm missing something really big. The strengths of a Lisp (per my research): Compact, expressive notation - More so than C#, yes... but I seem to be able to express those ideas in C# too. Implicit support for functional programming - C# with LINQ extension methods: mapcar = .Select( lambda ) mapcan = .Select( lambda ).Aggregate( (a,b) = a.Union(b) ) car/first = .First() cdr/rest = .Skip(1) .... etc. Lambda and higher-order function support - C# has this, and the syntax is arguably simpler: "(lambda (x) ( body ))" versus "x = ( body )" "#(" with "%", "%1", "%2" is nice in Clojure Method dispatch separated from the objects - C# has this through extension methods Multimethod dispatch - C# does not have this natively, but I could implement it as a function call in a few hours Code is Data (and Macros) - Maybe I haven't "gotten" macros, but I haven't seen a single example where the idea of a macro couldn't be implemented as a function; it doesn't change the "language", but I'm not sure that's a strength DSLs - Can only do it through function composition... but it works Untyped "exploratory" programming - for structs/classes, C#'s autoproperties and "object" work quite well, and you can easily escalate into stronger typing as you go along Runs on non-Windows hardware - Yeah, so? Outside of college, I've only known one person who doesn't run Windows at home, or at least a VM of Windows on *nix/Mac. (Then again, maybe this is more important than I thought and I've just been brainwashed...) The REPL for bottom-up design - Ok, I admit this is really really nice, and I miss it in C#. Things I'm missing in a Lisp (due to a mix of C#, .NET, Visual Studio, Resharper): Namespaces. Even with static methods, I like to tie them to a "class" to categorize their context (Clojure seems to have this, CL doesn't seem to.) Great compile and design-time support the type system allows me to determine "correctness" of the datastructures I pass around anything misspelled is underlined realtime; I don't have to wait until runtime to know code improvements (such as using an FP approach instead of an imperative one) are autosuggested GUI development tools: WinForms and WPF (I know Clojure has access to the Java GUI libraries, but they're entirely foreign to me.) GUI Debugging tools: breakpoints, step-in, step-over, value inspectors (text, xml, custom), watches, debug-by-thread, conditional breakpoints, call-stack window with the ability to jump to the code at any level in the stack (To be fair, my stint with Emacs+Slime seemed to provide some of this, but I'm partial to the VS GUI-driven approach) I really like the hype surrounding Lisps and I gave it a chance. But is there anything I can do in a Lisp that I can't do as well in C#? It might be a bit more verbose in C#, but I also have autocomplete. What am I missing? Why should I use Clojure/CL?

  • Behaviour Trees with irregular updates

    - by Robominister
    I'm interested in behaviour trees that aren't iterated every game tick, but every so often. (Edit: the tree could specify how many frames within the main game loop to wait before running its tick function again). Every theoretical implementation I have seen of behaviour trees talks of the tree search being carried out every game update - which seems necessary, because a leaf node (eg a behaviour, like 'return to base') needs to be constantly checked to see if is still running, failed or completed. Can anyone suggest how I might start implementing a tree that isnt run every tick, or point me in the direction of good material specific to this case (I am struggling to find anything)? My thoughts so far: action leaf nodes (when they start) must only push some kind of action object onto a list for an entity, rather than directly calling any code that makes the entity do something. The list of actions for the entity would be run every frame (update any that need to run, pop any that have completed from the list). the return state from a given action must be fed back into the tree, so that when we run the tree iteration again (and reach the same action leaf node - so the tree has so far determined that we ought to still be trying this action) - that the action has completed, or is still running etc. If my actual action code is running from an action list on an entity, then I possibly need to cancel previously running actions in the list - i am thinking that I can just delete the entire stack of queued up actions. I've seen the idea of ActionLists which block lower priority actions when a higher priority one is added, but this seems like very close logic to behaviour trees, and I dont want to be duplicating behaviour. This leaves me with some questions 1) How would I feed the action return state back into the tree? Its obvious I need to store some information relating to 'currently executing actions' on the entity, and check that in the tree tick, but I can't imagine how. 2) Does having a seperate behaviour tree (for deciding behaviour) and action list (for carrying out actual queued up actions) sound like a reasonable approach? 3) Is the approach of updating a behaviour tree irregularly actually used by anyone? It seems like a nice idea for budgeting ai search time when you have a lot of ai entities to process. (Edit) - I am also thinking about storing a single instance of a given behaviour tree in memory, and providing it by reference to any entity that uses it. So any information about what action was last selected for execution on an entity must be stored in a data context relative to the entity (which the tree can check). (I am probably answering my own questions as i go!) I hope I have expressed my questions adequately! Thanks in advance for any help :)

  • Office 2010 Professional Plus (Top 10 reasons to upgrade)

    - by mbcrump
    Being a huge nerd, I decided that I would go ahead and upgrade to the latest and greatest office. That being, Office 2010 Professional Plus. The biggest concern that I had was loosing all my mail settings from Outlook 2007. Thankfully, it upgrade gracefully and worked like a charm. So lets start this top 10 list. 1) You can upgrade without fear of loosing all your stuff! As you can tell by the screenshot below, you can select what you want to do. I selected to remove all previous versions.    2) Outlook conversations: Just like GMail, you can now group emails by conversations. This is simply awesome and a must have. 3) The ability to ignore conversations. If you are on a email thread that has nothing to do with you. Simply “ignore” the conversation and all emails go into the deleted folder. 4) Quick Steps, do you send an email to the same team member or group constantly. With quick steps, its just one click away. 5) Spell check in the Subject line! 6)  Easier Screenshots, built in just click the button. No more ALT-Printscreen for those that are not aware of the awesome SnagIT 10 that's out. 7) Open in protected view. When you open a document from an email attachment, it lets you know the file may be unsafe. You can click a button to enable editing. This is great for preventing macros.       8) Excel has always had a variety of charts and graphs available to visually depict data and trends. With Excel 2010, though, Microsoft has added a new feature called Sparklines, which allows you to place a mini-graph or trend line in a single cell. The Sparklines are a cool way to quickly and simply add a visual element without having to go through the effort of inserting a graph or chart that overwhelms the worksheet. 9) Contact actions. If you hover over a name in the form or fields on an email, you get a popup giving you several actions you can perform on the person such as adding them to your Outlook contacts, scheduling a meeting, viewing their stored contact information if they are already in your contacts, sending an instant message or even starting a telephone call. 10) Windows 7 Task Bar Context Menu – I love the jumplist. I don’t know how much that I would actually use it but it just rocks.

  • design a model for a system of dependent variables

    - by dbaseman
    I'm dealing with a modeling system (financial) that has dozens of variables. Some of the variables are independent, and function as inputs to the system; most of them are calculated from other variables (independent and calculated) in the system. What I'm looking for is a clean, elegant way to: define the function of each dependent variable in the system trigger a re-calculation, whenever a variable changes, of the variables that depend on it A naive way to do this would be to write a single class that implements INotifyPropertyChanged, and uses a massive case statement that lists out all the variable names x1, x2, ... xn on which others depend, and, whenever a variable xi changes, triggers a recalculation of each of that variable's dependencies. I feel that this naive approach is flawed, and that there must be a cleaner way. I started down the path of defining a CalculationManager<TModel> class, which would be used (in a simple example) something like as follows: public class Model : INotifyPropertyChanged { private CalculationManager<Model> _calculationManager = new CalculationManager<Model>(); // each setter triggers a "PropertyChanged" event public double? Height { get; set; } public double? Weight { get; set; } public double? BMI { get; set; } public Model() { _calculationManager.DefineDependency<double?>( forProperty: model => model.BMI, usingCalculation: (height, weight) => weight / Math.Pow(height, 2), withInputs: model => model.Height, model.Weight); } // INotifyPropertyChanged implementation here } I won't reproduce CalculationManager<TModel> here, but the basic idea is that it sets up a dependency map, listens for PropertyChanged events, and updates dependent properties as needed. I still feel that I'm missing something major here, and that this isn't the right approach: the (mis)use of INotifyPropertyChanged seems to me like a code smell the withInputs parameter is defined as params Expression<Func<TModel, T>>[] args, which means that the argument list of usingCalculation is not checked at compile time the argument list (weight, height) is redundantly defined in both usingCalculation and withInputs I am sure that this kind of system of dependent variables must be common in computational mathematics, physics, finance, and other fields. Does someone know of an established set of ideas that deal with what I'm grasping at here? Would this be a suitable application for a functional language like F#? Edit More context: The model currently exists in an Excel spreadsheet, and is being migrated to a C# application. It is run on-demand, and the variables can be modified by the user from the application's UI. Its purpose is to retrieve variables that the business is interested in, given current inputs from the markets, and model parameters set by the business.
