  • Enterprise Process Maps: A Process Picture worth a Million Words

    - by raul.goycoolea
    p { margin-bottom: 0.08in; }h1 { margin-top: 0.33in; margin-bottom: 0in; color: rgb(54, 95, 145); page-break-inside: avoid; }h1.western { font-family: "Cambria",serif; font-size: 14pt; }h1.cjk { font-family: "DejaVu Sans"; font-size: 14pt; }h1.ctl { font-size: 14pt; } Getting Started with Business Transformations A well-known proverb states that "A picture is worth a thousand words." In relation to Business Process Management (BPM), a credible analyst might have a few questions. What if the picture was taken from some particular angle, like directly overhead? What if it was taken from only an inch away or a mile away? What if the photographer did not focus the camera correctly? Does the value of the picture depend on who is looking at it? Enterprise Process Maps are analogous in this sense of relative value. Every BPM project (holistic BPM kick-off, enterprise system implementation, Service-oriented Architecture, business process transformation, corporate performance management, etc.) should be begin with a clear understanding of the business environment, from the biggest picture representations down to the lowest level required or desired for the particular project type, scope and objectives. The Enterprise Process Map serves as an entry point for the process architecture and is defined: the single highest level of process mapping for an organization. It is constructed and evaluated during the Strategy Phase of the Business Process Management Lifecycle. (see Figure 1) Fig. 1: Business Process Management Lifecycle Many organizations view such maps as visual abstractions, constructed for the single purpose of process categorization. This, in turn, results in a lesser focus on the inherent intricacies of the Enterprise Process view, which are explored in the course of this paper. With the main focus of a large scale process documentation effort usually underlying an ERP or other system implementation, it is common for the work to be driven by the desire to "get to the details," and to the type of modeling that will derive near-term tangible results. For instance, a project in American Pharmaceutical Company X is driven by the Director of IT. With 120+ systems in place, and a lack of standardized processes across the United States, he and the VP of IT have decided to embark on a long-term ERP implementation. At the forethought of both are questions, such as: How does my application architecture map to the business? What are each application's functionalities, and where do the business processes utilize them? Where can we retire legacy systems? Well-developed BPM methodologies prescribe numerous model types to capture such information and allow for thorough analysis in these areas. Process to application maps, Event Driven Process Chains, etc. provide this level of detail and facilitate the completion of such project-specific questions. These models and such analysis are appropriately carried out at a relatively low level of process detail. (see figure 2) Fig. 2: The Level Concept, Generic Process HierarchySome of the questions remaining are ones of documentation longevity, the continuation of BPM practice in the organization, process governance and ownership, process transparency and clarity in business process objectives and strategy. The Level Concept in Brief Figure 2 shows a generic, four-level process hierarchy depicting the breakdown of a "Process Area" into progressively more detailed process classifications. The number of levels and the names of these levels are flexible, and can be fit to the standards of the organization's chosen terminology or any other chosen reference model that makes logical sense for both short and long term process description. It is at Level 1 (in this case the Process Area level), that the Enterprise Process Map is created. This map and its contained objects become the foundation for a top-down approach to subsequent mapping, object relationship development, and analysis of the organization's processes and its supporting infrastructure. Additionally, this picture serves as a communication device, at an executive level, describing the design of the business in its service to a customer. It seems, then, imperative that the process development effort, and this map, start off on the right foot. Figuring out just what that right foot is, however, is critical and trend-setting in an evolving organization. Key Considerations Enterprise Process Maps are usually not as living and breathing as other process maps. Just as it would be an extremely difficult task to change the foundation of the Sears Tower or a city plan for the entire city of Chicago, the Enterprise Process view of an organization usually remains unchanged once developed (unless, of course, an organization is at a stage where it is capable of true, high-level process innovation). Regardless, the Enterprise Process map is a key first step, and one that must be taken in a precise way. What makes this groundwork solid depends on not only the materials used to construct it (process areas), but also the layout plan and knowledge base of what will be built (the entire process architecture). It seems reasonable that care and consideration are required to create this critical high level map... but what are the important factors? Does the process modeler need to worry about how many process areas there are? About who is looking at it? Should he only use the color pink because it's his boss' favorite color? Interestingly, and perhaps surprisingly, these are all valid considerations that may just require a bit of structure. Below are Three Key Factors to consider when building an Enterprise Process Map: Company Strategic Focus Process Categorization: Customer is Core End-to-end versus Functional Processes Company Strategic Focus As mentioned above, the Enterprise Process Map is created during the Strategy Phase of the Business Process Management Lifecycle. From Oracle Business Process Management methodology for business transformation, it is apparent that business processes exist for the purpose of achieving the strategic objectives of an organization. In a prescribed, top-down approach to process development, it must be ensured that each process fulfills its objectives, and in an aggregated manner, drives fulfillment of the strategic objectives of the company, whether for particular business segments or in a broader sense. This is a crucial point, as the strategic messages of the company must therefore resound in its process maps, in particular one that spans the processes of the complete business: the Enterprise Process Map. One simple example from Company X is shown below (see figure 3). Fig. 3: Company X Enterprise Process Map In reviewing Company X's Enterprise Process Map, one can immediately begin to understand the general strategic mindset of the organization. It shows that Company X is focused on its customers, defining 10 of its process areas belonging to customer-focused categories. Additionally, the organization views these end-customer-oriented process areas as part of customer-fulfilling value chains, while support process areas do not provide as much contiguous value. However, by including both support and strategic process categorizations, it becomes apparent that all processes are considered vital to the success of the customer-oriented focus processes. Below is an example from Company Y (see figure 4). Fig. 4: Company Y Enterprise Process Map Company Y, although also a customer-oriented company, sends a differently focused message with its depiction of the Enterprise Process Map. Along the top of the map is the company's product tree, overarching the process areas, which when executed deliver the products themselves. This indicates one strategic objective of excellence in product quality. Additionally, the view represents a less linear value chain, with strong overlaps of the various process areas. Marketing and quality management are seen as a key support processes, as they span the process lifecycle. Often, companies may incorporate graphics, logos and symbols representing customers and suppliers, and other objects to truly send the strategic message to the business. Other times, Enterprise Process Maps may show high level of responsibility to organizational units, or the application types that support the process areas. It is possible that hundreds of formats and focuses can be applied to an Enterprise Process Map. What is of vital importance, however, is which formats and focuses are chosen to truly represent the direction of the company, and serve as a driver for focusing the business on the strategic objectives set forth in that right. Process Categorization: Customer is Core In the previous two examples, processes were grouped using differing categories and techniques. Company X showed one support and three customer process categorizations using encompassing chevron objects; Customer Y achieved a less distinct categorization using a gradual color scheme. Either way, and in general, modeling of the process areas becomes even more valuable and easily understood within the context of business categorization, be it strategic or otherwise. But how one categorizes their processes is typically more complex than simply choosing object shapes and colors. Previously, it was stated that the ideal is a prescribed top-down approach to developing processes, to make certain linkages all the way back up to corporate strategy. But what about external influences? What forces push and pull corporate strategy? Industry maturity, product lifecycle, market profitability, competition, etc. can all drive the critical success factors of a particular business segment, or the company as a whole, in addition to previous corporate strategy. This may seem to be turning into a discussion of theory, but that is far from the case. In fact, in years of recent study and evolution of the way businesses operate, cross-industry and across the globe, one invariable has surfaced with such strength to make it undeniable in the game plan of any strategy fit for survival. That constant is the customer. Many of a company's critical success factors, in any business segment, relate to the customer: customer retention, satisfaction, loyalty, etc. Businesses serve customers, and so do a business's processes, mapped or unmapped. The most effective way to categorize processes is in a manner that visualizes convergence to what is core for a company. It is the value chain, beginning with the customer in mind, and ending with the fulfillment of that customer, that becomes the core or the centerpiece of the Enterprise Process Map. (See figure 5) Fig. 5: Company Z Enterprise Process Map Company Z has what may be viewed as several different perspectives or "cuts" baked into their Enterprise Process Map. It has divided its processes into three main categories (top, middle, and bottom) of Management Processes, the Core Value Chain and Supporting Processes. The Core category begins with Corporate Marketing (which contains the activities of beginning to engage customers) and ends with Customer Service Management. Within the value chain, this company has divided into the focus areas of their two primary business lines, Foods and Beverages. Does this mean that areas, such as Strategy, Information Management or Project Management are not as important as those in the Core category? No! In some cases, though, depending on the organization's understanding of high-level BPM concepts, use of category names, such as "Core," "Management" or "Support," can be a touchy subject. What is important to understand, is that no matter the nomenclature chosen, the Core processes are those that drive directly to customer value, Support processes are those which make the Core processes possible to execute, and Management Processes are those which steer and influence the Core. Some common terms for these three basic categorizations are Core, Customer Fulfillment, Customer Relationship Management, Governing, Controlling, Enabling, Support, etc. End-to-end versus Functional Processes Every high and low level of process: function, task, activity, process/work step (whatever an organization calls it), should add value to the flow of business in an organization. Suppose that within the process "Deliver package," there is a documented task titled "Stop for ice cream." It doesn't take a process expert to deduce the room for improvement. Though stopping for ice cream may create gain for the one person performing it, it likely benefits neither the organization nor, more importantly, the customer. In most cases, "Stop for ice cream" wouldn't make it past the first pass of To-Be process development. What would make the cut, however, would be a flow of tasks that, each having their own value add, build up to greater and greater levels of process objective. In this case, those tasks would combine to achieve a status of "package delivered." Figure 3 shows a simple example: Just as the package can only be delivered (outcome of the process) without first being retrieved, loaded, and the travel destination reached (outcomes of the process steps), some higher level of process "Play Practical Joke" (e.g., main process or process area) cannot be completed until a package is delivered. It seems that isolated or functionally separated processes, such as "Deliver Package" (shown in Figure 6), are necessary, but are always part of a bigger value chain. Each of these individual processes must be analyzed within the context of that value chain in order to ensure successful end-to-end process performance. For example, this company's "Create Joke Package" process could be operating flawlessly and efficiently, but if a joke is never developed, it cannot be created, so the end-to-end process breaks. Fig. 6: End to End Process Construction That being recognized, it is clear that processes must be viewed as end-to-end, customer-to-customer, and in the context of company strategy. But as can also be seen from the previous example, these vital end-to-end processes cannot be built without the functionally oriented building blocks. Without one, the other cannot be had, or at least not in a complete and organized fashion. As it turns out, but not discussed in depth here, the process modeling effort, BPM organizational development, and comprehensive coverage cannot be fully realized without a semi-functional, process-oriented approach. Then, an Enterprise Process Map should be concerned with both views, the building blocks, and access points to the business-critical end-to-end processes, which they construct. Without the functional building blocks, all streams of work needed for any business transformation would be lost mess of process disorganization. End-to-end views are essential for utilization in optimization in context, understanding customer impacts, base-lining all project phases and aligning objectives. Including both views on an Enterprise Process Map allows management to understand the functional orientation of the company's processes, while still providing access to end-to-end processes, which are most valuable to them. (See figures 7 and 8). Fig. 7: Simplified Enterprise Process Map with end-to-end Access Point The above examples show two unique ways to achieve a successful Enterprise Process Map. The first example is a simple map that shows a high level set of process areas and a separate section with the end-to-end processes of concern for the organization. This particular map is filtered to show just one vital end-to-end process for a project-specific focus. Fig. 8: Detailed Enterprise Process Map showing connected Functional Processes The second example shows a more complex arrangement and categorization of functional processes (the names of each process area has been removed). The end-to-end perspective is achieved at this level through the connections (interfaces at lower levels) between these functional process areas. An important point to note is that the organization of these two views of the Enterprise Process Map is dependent, in large part, on the orientation of its audience, and the complexity of the landscape at the highest level. If both are not apparent, the Enterprise Process Map is missing an opportunity to serve as a holistic, high-level view. Conclusion In the world of BPM, and specifically regarding Enterprise Process Maps, a picture can be worth as many words as the thought and effort that is put into it. Enterprise Process Maps alone cannot change an organization, but they serve more purposes than initially meet the eye, and therefore must be designed in a way that enables a BPM mindset, business process understanding and business transformation efforts. Every Enterprise Process Map will and should be different when looking across organizations. Its design will be driven by company strategy, a level of customer focus, and functional versus end-to-end orientations. This high-level description of the considerations of the Enterprise Process Maps is not a prescriptive "how to" guide. However, a company attempting to create one may not have the practical BPM experience to truly explore its options or impacts to the coming work of business process transformation. The biggest takeaway is that process modeling, at all levels, is a science and an art, and art is open to interpretation. It is critical that the modeler of the highest level of process mapping be a cognoscente of the message he is delivering and the factors at hand. Without sufficient focus on the design of the Enterprise Process Map, an entire BPM effort may suffer. For additional information please check: Oracle Business Process Management.

  • "Could not load file or assembly 'XXX.YYY' or one of its dependencies. The system cannot find the file specified."

    - by Niall Collins
    I have a .net visual studio solution with a number of projects (class libraries and a web application). I did some refractoring which moved files between projects, created new projects, deleted ones not being used and renamed some existing projects. The solution builds without an issue but when I run the web application, the following exception occurs: "Could not load file or assembly 'XXX.YYY' or one of its dependencies. The system cannot find the file specified." The project called XXX.YYY which was deleted in the refractoring outputed a dll called XXX.YYY. But this isnt used anywhere in the application. I deleted the web applications obj directory and bin folder and rebuild but it still occurs. Anyone have any ideas when this might be occurring, any tips??

  • Recent ImageMagick on CentOS 6.3

    - by organicveggie
    I'm having a terrible time trying to get a recent version of ImageMagick installed on a CentOS 6.3 x86_64 server. First, I downloaded the RPM from the ImageMagick site and tried to install it. That failed due to missing dependencies: error: Failed dependencies: libHalf.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libIex.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libIlmImf.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libImath.so.4()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 libltdl.so.3()(64bit) is needed by ImageMagick-6.8.0-4.x86_64 I have libtool-ltdl installed, but that includes libltdl.so.7, not libltdl.so.4. I have a similar problem with libHalf, libIex, libIlmImf and libImath. Typically, you can install OpenEXR to get those dependencies. Unfortunately, CentOS 6.3 includes OpenEXR 1.6.1, which includes ilmbase-devel 1.0.1. And that release of ilmbase-devel includes newer versions of those dependencies: libHalf.so.6 libIex.so.6 libIlmImf.so.6 libImath.so.6 I next tried following the instructions for installing ImageMagick from source. No luck there either. I get a build error: RPM build errors: File not found by glob: /home/sean/rpmbuild/BUILDROOT/ImageMagick-6.8.0-4.x86_64/usr/lib64/ImageMagick-6.8.0/modules-Q16/coders/djvu.* I even re-ran configure to explicitly exclude djvu and I still get the same error. At this point, I'm pulling my hair out. What's the easiest way to get a relatively recent version of ImageMagick ( 6.7) installed on CentOS 6.3? Does someone offer RPMs with dependencies somewhere?

  • What is a good method to solve cabal install problems?

    - by sp3ctum
    I've used the cabal package manager for Haskell programs to install libraries and new projects that I've cloned from some repositories. More often than not, I keep running into problems. Most projects make installing them seem super easy, but in my case that's not always true - sometimes they are very hard to get running. Some are so hard, in fact, that I've lost interest in the project solely because of not being able to install it. So instead of complaining, I'd like to ask what I should do to better this situation. I'd like to use my most recent problem as an example. I'm interested in trying out the Gitit project. It's a promising looking personal wiki that runs on various version control systems. So here's what I've done: Clone from Github run cabal install in the project directory like I'm told on the project install page: mika@eka:~/git/gitit$ ls BLUETRIP-LICENSE CHANGES HCAR-gitit.tex LICENSE Network README.markdown RELANN-0.6.1 Setup.lhs TANGOICONS YUI-LICENSE data expireGititCache.hs gitit.cabal gitit.hs plugins mika@eka:~/git/gitit$ cabal install Resolving dependencies... cabal: cannot configure happstack-server-7.0.7. It requires base64-bytestring ==1.0.* For the dependency on base64-bytestring ==1.0.* there are these packages: base64-bytestring-1.0.0.0. However none of them are available. base64-bytestring-1.0.0.0 was excluded because gitit-0.10 requires base64-bytestring ==0.1.* mika@eka:~/git/gitit$ So now I'm thinking: well, I'll install happstack-server on its own, maybe that will work: mika@eka:~/git/gitit$ cabal install happstack-server Resolving dependencies... Warning: happstack-server.cabal: Ignoring unknown section type: test-suite Configuring happstack-server-7.0.7... cabal: At least the following dependencies are missing: blaze-html ==0.5.*, hslogger >=1.0.2, monad-control ==0.3.*, network >=2.2.3, sendfile >=0.7.1 && <0.8, system-filepath >=0.3.1, text >=0.10 && <0.12, threads >=0.5, transformers-base ==0.4.* cabal: Error: some packages failed to install: happstack-server-7.0.7 failed during the configure step. The exception was: ExitFailure 1 So looks like there are some dependencies missing. But isn't installing these dependencies the whole point of using cabal in the first place? What should I do? File bug reports (to which project?), install the dependencies manually or something else? Bonus points for explaining what causes these kinds of problems.

  • Uninstall last n of ports/packages

    - by Radio
    While compiling some port, I realized that it depends on 1000+ of other ports and will install forever until I die or my disk is full (my hdd is really small). I interrupted make install clean. How do I uninstall and clean those dependencies which have already been built and installed? (there are at least 100+ of them) pkg_cutleaves wont work in this case, since the main port wasn't registered yet. Please help. FreeBSD 9.0-RELEASE amd64 EDIT: Another way to ask this question: How can I see all dependencies for a non-registered port, and all subdependencies for those dependencies, independent with previously installed ports or their [sub]dependencies?

  • deploying a Python application from a PHP developer

    - by user1218776
    I'm a little confused on the deployment process for Python. Let's say you create a brand new project with virtualenv source bin/activate pip install a few libraries write a simple hello world app pip freeze the dependencies When I deploy this code into a machine, do I need first make sure the machine is sourced before installing dependencies? I don't mean to sound like a total noob but in the PHP world, I don't have to worry about this because it's already part of the project. All the dependencies are registered with the autoloader in place. The steps would be: rsync the files (or any other method) source bin/activate pip install the dependencies from the pip freeze output file It feels awkward, or just wrong and very error prone. What are the correct steps to make? I've searched around but it seems many tutorials/articles make an assumption that anyone reading the article has past python experience (imo).

    I started a rails application from scratch, using Rails 2.3.5, and installed oauth-plugin. The installation was done by running script/plugin install git://github.com/pelle/oauth-plugin.git.

  • Back to Basics: When does a .NET Assembly Dependency get loaded

    - by Rick Strahl
    When we work on typical day to day applications, it's easy to forget some of the core features of the .NET framework. For me personally it's been a long time since I've learned about some of the underlying CLR system level services even though I rely on them on a daily basis. I often think only about high level application constructs and/or high level framework functionality, but the low level stuff is often just taken for granted. Over the last week at DevConnections I had all sorts of low level discussions with other developers about the inner workings of this or that technology (especially in light of my Low Level ASP.NET Architecture talk and the Razor Hosting talk). One topic that came up a couple of times and ended up a point of confusion even amongst some seasoned developers (including some folks from Microsoft <snicker>) is when assemblies actually load into a .NET process. There are a number of different ways that assemblies are loaded in .NET. When you create a typical project assemblies usually come from: The Assembly reference list of the top level 'executable' project The Assembly references of referenced projects Dynamically loaded at runtime via AppDomain/Reflection loading In addition .NET automatically loads mscorlib (most of the System namespace) the boot process that hosts the .NET runtime in EXE apps, or some other kind of runtime hosting environment (runtime hosting in servers like IIS, SQL Server or COM Interop). In hosting environments the runtime host may also pre-load a bunch of assemblies on its own (for example the ASP.NET host requires all sorts of assemblies just to run itself, before ever routing into your user specific code). Assembly Loading The most obvious source of loaded assemblies is the top level application's assembly reference list. You can add assembly references to a top level application and those assembly references are then available to the application. In a nutshell, referenced assemblies are not immediately loaded - they are loaded on the fly as needed. So regardless of whether you have an assembly reference in a top level project, or a dependent assembly assemblies typically load on an as needed basis, unless explicitly loaded by user code. The same is true of dependent assemblies. To check this out I ran a simple test: I have a utility assembly Westwind.Utilities which is a general purpose library that can work in any type of project. Due to a couple of small requirements for encoding and a logging piece that allows logging Web content (dependency on HttpContext.Current) this utility library has a dependency on System.Web. Now System.Web is a pretty large assembly and generally you'd want to avoid adding it to a non-Web project if it can be helped. So I created a Console Application that loads my utility library: You can see that the top level Console app a reference to Westwind.Utilities and System.Data (beyond the core .NET libs). The Westwind.Utilities project on the other hand has quite a few dependencies including System.Web. I then add a main program that accesses only a simple utillity method in the Westwind.Utilities library that doesn't require any of the classes that access System.Web: static void Main(string[] args) { Console.WriteLine(StringUtils.NewStringId()); Console.ReadLine(); } StringUtils.NewStringId() calls into Westwind.Utilities, but it doesn't rely on System.Web. Any guesses what the assembly list looks like when I stop the code on the ReadLine() command? I'll wait here while you think about it… … … So, when I stop on ReadLine() and then fire up Process Explorer and check the assembly list I get: We can see here that .NET has not actually loaded any of the dependencies of the Westwind.Utilities assembly. Also not loaded is the top level System.Data reference even though it's in the dependent assembly list of the top level project. Since this particular function I called only uses core System functionality (contained in mscorlib) there's in fact nothing else loaded beyond the main application and my Westwind.Utilities assembly that contains the method accessed. None of the dependencies of Westwind.Utilities loaded. If you were to open the assembly in a disassembler like Reflector or ILSpy, you would however see all the compiled in dependencies. The referenced assemblies are in the dependency list and they are loadable, but they are not immediately loaded by the application. In other words the C# compiler and .NET linker are smart enough to figure out the dependencies based on the code that actually is referenced from your application and any dependencies cascading down into the dependencies from your top level application into the referenced assemblies. In the example above the usage requirement is pretty obvious since I'm only calling a single static method and then exiting the app, but in more complex applications these dependency relationships become very complicated - however it's all taken care of by the compiler and linker figuring out what types and members are actually referenced and including only those assemblies that are in fact referenced in your code or required by any of your dependencies. The good news here is: That if you are referencing an assembly that has a dependency on something like System.Web in a few places that are not actually accessed by any of your code or any dependent assembly code that you are calling, that assembly is never loaded into memory! Some Hosting Environments pre-load Assemblies The load behavior can vary however. In Console and desktop applications we have full control over assembly loading so we see the core CLR behavior. However other environments like ASP.NET for example will preload referenced assemblies explicitly as part of the startup process - primarily to minimize load conflicts. Specifically ASP.NET pre-loads all assemblies referenced in the assembly list and the /bin folder. So in Web applications it definitely pays to minimize your top level assemblies if they are not used. Understanding when Assemblies Load To clarify and see it actually happen what I described in the first example , let's look at a couple of other scenarios. To see assemblies loading at runtime in real time lets create a utility function to print out loaded assemblies to the console: public static void PrintAssemblies() { var assemblies = AppDomain.CurrentDomain.GetAssemblies(); foreach (var assembly in assemblies) { Console.WriteLine(assembly.GetName()); } } Now let's look at the first scenario where I have class method that references internally uses System.Web. In the first scenario lets add a method to my main program like this: static void Main(string[] args) { Console.WriteLine(StringUtils.NewStringId()); Console.ReadLine(); PrintAssemblies(); } public static void WebLogEntry() { var entry = new WebLogEntry(); entry.UpdateFromRequest(); Console.WriteLine(entry.QueryString); } UpdateFromWebRequest() internally accesses HttpContext.Current to read some information of the ASP.NET Request object so it clearly needs a reference System.Web to work. In this first example, the method that holds the calling code is never called, but exists as a static method that can potentially be called externally at some point. What do you think will happen here with the assembly loading? Will System.Web load in this example? No - it doesn't. Because the WebLogEntry() method is never called by the mainline application (or anywhere else) System.Web is not loaded. .NET dynamically loads assemblies as code that needs it is called. No code references the WebLogEntry() method and so System.Web is never loaded. Next, let's add the call to this method, which should trigger System.Web to be loaded because a dependency exists. Let's change the code to: static void Main(string[] args) { Console.WriteLine(StringUtils.NewStringId()); Console.WriteLine("--- Before:"); PrintAssemblies(); WebLogEntry(); Console.WriteLine("--- After:"); PrintAssemblies(); Console.ReadLine(); } public static void WebLogEntry() { var entry = new WebLogEntry(); entry.UpdateFromRequest(); Console.WriteLine(entry.QueryString); } Looking at the code now, when do you think System.Web will be loaded? Will the before list include it? Yup System.Web gets loaded, but only after it's actually referenced. In fact, just until before the call to UpdateFromRequest() System.Web is not loaded - it only loads when the method is actually called and requires the reference in the executing code. Moral of the Story So what have we learned - or maybe remembered again? Dependent Assembly References are not pre-loaded when an application starts (by default) Dependent Assemblies that are not referenced by executing code are never loaded Dependent Assemblies are just in time loaded when first referenced in code All of this is nothing new - .NET has always worked like this. But it's good to have a refresher now and then and go through the exercise of seeing it work in action. It's not one of those things we think about everyday, and as I found out last week, I couldn't remember exactly how it worked since it's been so long since I've learned about this. And apparently I'm not the only one as several other people I had discussions with in relation to loaded assemblies also didn't recall exactly what should happen or assumed incorrectly that just having a reference automatically loads the assembly. The moral of the story for me is: Trying at all costs to eliminate an assembly reference from a component is not quite as important as it's often made out to be. For example, the Westwind.Utilities module described above has a logging component, including a Web specific logging entry that supports pulling information from the active HTTP Context. Adding that feature requires a reference to System.Web. Should I worry about this in the scope of this library? Probably not, because if I don't use that one class of nearly a hundred, System.Web never gets pulled into the parent process. IOW, System.Web only loads when I use that specific feature and if I am, well I clearly have to be running in a Web environment anyway to use it realistically. The alternative would be considerably uglier: Pulling out the WebLogEntry class and sticking it into another assembly and breaking up the logging code. In this case - definitely not worth it. So, .NET definitely goes through some pretty nifty optimizations to ensure that it loads only what it needs and in most cases you can just rely on .NET to do the right thing. Sometimes though assembly loading can go wrong (especially when signed and versioned local assemblies are involved), but that's subject for a whole other post…© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET  CSharp   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); })();

  • How to install rgdal on Ubuntu 12.10?

    - by radek
    I'm strugling to install rgdal library on Ubuntu 12.10. Installation from within R results in error: Error: gdal-config not found The gdal-config script distributed with GDAL could not be found. If you have not installed the GDAL libraries, you can download the source from http://www.gdal.org/ If you have installed the GDAL libraries, then make sure that gdal-config is in your path. Try typing gdal-config at a shell prompt and see if it runs. If not, use: --configure-args='--with-gdal-config=/usr/local/bin/gdal-config' with appropriate values for your installation. ERROR: configuration failed for package ‘rgdal’ * removing ‘/home/rdk/R/x86_64-pc-linux-gnu-library/2.15/rgdal’ Warning in install.packages : installation of package ‘rgdal’ had non-zero exit status R-sig-Geo, this two SE questions and other websites pointed me to the requirements of libgdal1-dev. But when I tried sudo apt-get install libgdal1-dev I end up with another error message Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

  • LINQ to Twitter Maintenance Feedback

    - by Joe Mayo
    Originally posted on: http://geekswithblogs.net/WinAZ/archive/2013/06/16/linq-to-twitter-maintenance-feedback.aspxIt’s always fun to receive positive feedback on your work. If you receive a sufficient amount of positive feedback, you know you’re doing something right. Sometimes, people provide negative feedback too. There are a couple ways to handle it: come back fighting or engage for clarification. The way you handle the negative feedback depends on what your goals are. Feedback Approaches If you know the feedback is incorrect and you need to promote your idea or product, you might want to come back fighting. The feedback might just be comments by a troll or competitor wanting to spread FUD. However, this could be the totally wrong approach if you misjudge the source and intentions of the feedback. In a lot of cases, feedback is a golden opportunity. Sometimes, a problem exists that you either don’t know about or don’t realize the true impact of the problem. If you decide to come back fighting, you might loose the opportunity to learn something new. However, if you engage the person providing the feedback, looking for clarification, you might learn something very important. Negative feedback and it’s clarification can lead to the collection of useful and actionable data. In my case, something that prompted this blog post, I noticed someone who tweeted a negative comment about LINQ to Twitter. Normally, any less than stellar comments are usually from folks that need help – so I help if I can. This was different. I was like “Don’t use LINQ to Twitter”. This is an open source project, the comment didn’t come from a competing project, and  sounded more like an expression of frustration. So I engaged. Not only did the person respond, but I got some decent quality feedback. What’s also interesting is a couple other side conversations sprouted on the subject, which gave me more useful data. LINQ to Twitter Thread Actions Essentially, this particular issue centered around maintenance. There are actually several sub-issues at play here: dependencies, error handling, debugging, and visibility. I’ll describe each one and my interpretation. Dependencies Dependencies are where a library has references to other libraries. This means that when you build your application, you need DLLs for the entire dependency graph for your application. There are several potential problems with this that include more libraries for configuration management, potential versioning mismatches, and lack of cross-platform support. In the early days of LINQ to Twitter, I allowed developers to contribute and add dependencies, but it became very problematic (for reasons stated). It was like a ball and chain that kept me from moving forward. So, I refactored and pulled other open-source into my project to eliminate external dependencies. This lets me fix the code in my project without relying on someone else to upgrade or fix their DLL. The motivation for this was from early negative feedback that translated as important data and acted on it. Today, LINQ to Twitter has zero dependencies. Note: Rejecting good code from community members who worked hard to make your project better is a painful experience in itself. I have to point out that any contribution was not in vain because they had a positive influence on my subsequent refactoring that resulted in a better developer experience. Error Handling Error handling has been a problem in the past. I have this combination of supporting both synchronous and asynchronous (APM) processing that can be complex at times. Within the last 6 months, I did a fair amount of refactoring to detect errors and process them properly. I also refactored TwitterQueryException so it includes important data from Twitter. During this refactoring, I’ve made breaking changes that I felt would improve the development experience (small things like renaming a callback property to Exception, rather than Error). I think the async error handling is much better than it was a year ago. For all the work I’ve done, there is more to do. I think that a combination of more error handling support, e.g. improving semantics, and education through documentation and samples will improve the error handling story. Because of what I’ve done so far, it isn’t bad, but I see opportunities for improvement. Debugging Debugging can be painful. Here’s why: you have multiple layers of technology to navigate and figure out where the real problem is – Twitter API, Security, HTTP, LINQ to Twitter, and application. You can probably add your own nuances to that list, but the point is that debugging in this environment can be complex. I think that my plans for error handling will contribute to making the debugging process easier. However, there’s more I can do in the way of documentation and guidance. Some of the questions to be answered revolve around when something goes wrong, how does the developer figure out that there is a problem, what the problem is, and what to do about it. One example that has gone a long way to helping LINQ to Twitter developers is the 401 FAQ. A 401 Unauthorized is the error that the Twitter API returns when a use isn’t able to authenticate and is one of the most difficult problems faced by LINQ to Twitter developers. What I did was read guidance from Twitter and collect techniques from my own development and actions helping other developers to compile an extensive list of reasons for the 401 and ways to fix the problem. At one time, over half of the questions I answered in the forums were to help solve 401 issues. After publishing the 401 FAQ, I rarely get a 401 question and it’s because the person didn’t know about the FAQ. If the person is too lazy to read the FAQ, that’s not my issue, but the results in support issues have been dramatic. I think debugging can benefit from the education and documentation approach, but I’m always open to suggestions on whatever else I can do. Visibility Visibility is a nuance of the error handling/debugging discussion but is deeply rooted in comfort and control. The questions to ask in this area are what is happening as my code runs and how testable is the code. In support of these areas, LINQ to Twitter does have logging and TwitterContext properties that help see what’s happening on requests. The logging functionality allows any developer to connect a TextWriter to the Log property of TwitterContext to see what’s happening. Further, TwitterContext has a Headers property to see the headers Twitter returns and a RawResults property to show the Json string Twitter returns. From a testing perspective, I’ve been able to write hundreds of unit tests, over 600 when this post is published, and growing. If you write your own library, you have full control over all of these aspects. The tradeoff here is that while you have access to the LINQ to Twitter source code and modify it for all the visibility, LINQ to Twitter *will* change (which is good) and you will have to figure out how to merge that with your changes (which is hard). The fact is that this is a limitation of any 3rd party library, not just LINQ to Twitter. So, it’s a design decision where the tradeoff is between control and productivity. That said, there are things I can do with LINQ to Twitter to make the visibility story more compelling. I think there are opportunities to improve diagnostics. This would be a ton of work because it would need to provide multi-level logging that can be tuned for production and support any logging provider you want to attach. I’ve considered approaches such as how the new Semantic Logging application block connects to Windows Error Reporting as a potential target. Whatever I do would need to be extensible without creating native external dependencies. e.g. how many 3rd party libraries force a dependency on a logging framework that you don’t use. So, this won’t be an easy feat, but I believe it can be part of the roadmap. I think that a lot of developers are unaware of existing visibility features, so the first step would be to provide more documentation and guidance. My thought are that this would lead to more feedback that will help improve this area. Summary Recent feedback highlights some of items that are important to LINQ to Twitter developers, such as dependencies, error handling, debugging, and visibility. I know that there are maintenance issues that have been problems for LINQ to Twitter developers in the past. I’ve done a lot of work in this area, such as improving error handling, adding visibility features, and providing extensive API documentation. That said, there is more to be done to make LINQ to Twitter the best Twitter API experience available for .NET developers and I welcome anyone’s thoughts on what I’ve written here or new improvements. @JoeMayo

  • How you can extend Tasklists in Fusion Applications

    - by Elie Wazen
    In this post we describe the process of modifying and extending a Tasklist available in the Regional Area of a Fusion Applications UI Shell. This is particularly useful to Customers who would like to expose Setup Tasks (generally available in the Fusion Setup Manager application) in the various functional pillars workareas. Oracle Composer, the tool used to implement such extensions allows changes to be made at runtime. The example provided in this document is for an Oracle Fusion Financials page. Let us examine the case of a customer role who requires access to both, a workarea and its associated functional tasks, and to an FSM (setup) task.  Both of these tasks represent ADF Taskflows but each is accessible from a different page.  We will show how an FSM task is added to a Functional tasklist and made accessible to a user from within a single workarea, eliminating the need to navigate between the FSM application and the Functional workarea where transactions are conducted. In general, tasks in Fusion Applications are grouped in two ways: Setup tasks are grouped in tasklists available to implementers in the Functional Setup Manager (FSM). These Tasks are accessed by implementation users and in general do not represent daily operational tasks that fit into a functional business process and were consequently included in the FSM application. For these tasks, the primary organizing principle is precedence between tasks. If task "Manage Suppliers" has prerequisites, those tasks must precede it in a tasklist. Task Lists are organized to efficiently implement an offering. Tasks frequently performed as part of business process flows are made available as links in the tasklist of their corresponding menu workarea. The primary organizing principle in the menu and task pane entries is to group tasks that are generally accessed together. Customizing a tasklist thus becomes required for business scenarios where a task packaged under FSM as a setup task, is for a particular customer a regular maintenance task that is accessed for record updates or creation as part of normal operational activities and where the frequency of this access merits the inclusion of that task in the related operational tasklist A user with the role of maintaining Journals in General Ledger is also responsible for maintaining Chart of Accounts Mappings.  In the Fusion Financials Product Family, Manage Journals is a task available from within the Journals Menu whereas Chart of Accounts Mapping is available via FSM under the Define Chart of Accounts tasklist Figure 1. The Manage Chart of Accounts Mapping Task in FSM Figure 2. The Manage Journals Task in the Task Pane of the Journals Workarea Our goal is to simplify cross task navigation and allow the user to access both tasks from a single tasklist on a single page without having to navigate to FSM for the Mapping task and to the Journals workarea for the Manage task. To accomplish that, we use Oracle Composer to customize  the Journals tasklist by adding to it the Mapping task. Identify the Taskflow name and path of the FSM Task The first step in our process is to identify the underlying taskflow for the Manage Chart of Accounts Mappings task. We select to Setup and Maintenance from the Navigator to launch the FSM Application, and we query the task from Manage Tasklists and Tasks Figure 3. Task Details including Taskflow path The Manage Chart of Accounts Mapping Task Taskflow is: /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/coaMappings/ui/flow /CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow We copy that value and use it later as a parameter to our new task in the customized Journals Tasklist. Customize the Journals Page A user with Administration privileges can start the run time customization directly from the Administration Menu of the Global Area.  This customization is done at the Site level and once implemented becomes available to all users with access to the Journals Workarea. Figure 4.  Customization Menu The Oracle Composer Window is displayed in the same browser and the Hierarchy of the page component is displayed and available for modification. Figure 5.  Oracle Composer In the composer Window select the PanelFormLayout node and click on the Edit Button.  Note that the selected component is simultaneously highlighted in the lower pane in the browser. In the Properties popup window, select the Tasks List and Task Properties Tab, where the user finds the hierarchy of the Tasklist and is able to Edit nodes or create new ones. src="https://blogs.oracle.com/FunctionalArchitecture/resource/TL5.jpg" Figure 6.  The Tasklist in edit mode Add a Child Task to the Tasklist In the Edit Window the user will now create a child node at the desired level in the hierarchy by selecting the immediate parent node and clicking on the insert node button.  This process requires four values to be set as described in Table 1 below. Parameter Value How to Determine the Value Focus View Id /JournalEntryPage This is the Focus View ID of the UI Shell where the Tasklist we want to customize is.  A simple way to determine this value is to copy it from any of the Standard tasks on the Tasklist Label COA Mapping This is the Display name of the Task as it will appear in the Tasklist Task Type dynamicMain If the value is dynamicMain, the page contains a new link in the Regional Area. When you click the link, a new tab with the loaded task opens Taskflowid /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/ coaMappings/ui/flow/ CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow This is the Taskflow path we retrieved from the Task Definition in FSM earlier in the process Table 1.  Parameters and Values for the Task to be added to the customized Tasklist Figure 7.   The parameters window of the newly added Task   Access the FSM Task from the Journals Workarea Once the FSM task is added and its parameters defined, the user saves the record, closes the Composer making the new task immediately available to users with access to the Journals workarea (Refer to Figure 8 below). Figure 8.   The COA Mapping Task is now visible and can be invoked from the Journals Workarea   Additional Considerations If a Task Flow is part of a product that is deployed on the same app server as the Tasklist workarea then that task flow can be added to a customized tasklist in that workarea. Otherwise that task flow can be invoked from its parent product’s workarea tasklist by selecting that workarea from the Navigator menu. For Example The following Taskflows  belong respectively to the Subledger Accounting, and to the General Ledger Products.  /WEB-INF/oracle/apps/financials/subledgerAccounting/accountingMethodSetup/mappingSets/ui/flow/MappingSetFlow.xml#MappingSetFlow /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/coaMappings/ui/flow/CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow Since both the Subledger Accounting and General Ledger products are part of the LedgerApp J2EE Applicaton and are both deployed on the General Ledger Cluster Server (Figure 8 below), the user can add both of the above taskflows to the  tasklist in the  /JournalEntryPage FocusVIewID Workarea. Note:  both FSM Taskflows and Functional Taskflows can be added to the Tasklists as described in this document Figure 8.   The Topology of the Fusion Financials Product Family. Note that SubLedger Accounting and General Ledger are both deployed on the Ledger App Conclusion In this document we have shown how an administrative user can edit the Tasklist in the Regional Area of a Fusion Apps page using Oracle Composer. This is useful for cases where tasks packaged in different workareas are frequently accessed by the same user. By making these tasks available from the same page, we minimize the number of steps in the navigation the user has to do to perform their transactions and queries in Fusion Apps.  The example explained above showed that tasks classified as Setup tasks, meaning made accessible to implementation users from the FSM module can be added to the workarea of their respective Fusion application. This eliminates the need to navigate to FSM to access tasks that are both setup and regular maintenance tasks.

  • Database Table Prefixes

    - by DoctorMick
    We're having a few discussions at work around the naming of our database tables. We're working on a large application with approx 100 database tables (ok, so it isn't that large), most of which can be categorized in to different functional area, and we're trying to work out the best way of naming/organizing these within an Oracle database. The three current options are: Create the different functional areas in separate schemas. Create everything in the same schema but prefix the tables with the functional area Create everything in the same schema with no prefixes We have various pro's and con's around each one but I'd be interested to hear everyone's opinions on what the best solution is.

  • Can't install wine (or ia32-libs) in Ubuntu 12.10 64 bit

    - by carestad
    As already pointed out here, people seems to have issues with installing wine in the latest version of Ubuntu. I'm suspecting this only happens with 64 bit users. For example, when trying to install wine, wine1.4, wine1.4:i386, wine1.5, wine1.5:i386, ia32-libs or ia32-libs:i386 with apt-get, I get a lot of dependency errors. Doing a sudo apt-get -f install doesn't seem to do the trick, neither does using aptitude. The errors I get is normally that the packages depend on some :i386 package, but installing those manually doesn't work either because they also have dependency issues (isn't APT supposed to do this automatically?!). I also downloaded CrossOver today and tried installing the .deb manually, but the dependency issues show up there as well. When running sudo apt-get -f install after trying to install the CrossOver .deb, apt-get wants to purge the following packages: ia32-crossover intel-gpu-tools libdrm-nouveau2 libgl1-mesa-dri libva-x11-1 ubuntu-desktop vlc xorg xserver-xorg-video-ati xserver-xorg-video-intel xserver-xorg-video-modesetting xserver-xorg-video-openchrome xserver-xorg-video-radeon xserver-xorg-video-vmware What I've tried so far (and didn't work): Installing synaptic, reloading my repositories, searching for ia32 and installing ia32-libs. Using Ubuntu Software Center to install Wine and ia32-libs. Using apt-get and aptitude to install all the differend varieties of the wine packages, both with and without the :i386 and -amd64 suffixes in package names. Disabling the universe and multiverse repos, run a sudo apt-get update and then re-enable them again. Boot a newly downloaded Ubuntu 12.10 x64 live USB and try to install all the different packages there. What I haven't tried (yet): Boot a newly downloaded Ubuntu 12.10 x32 image and try to install wine there (I'm just guessing that will work). Reinstall Ubuntu.

  • F# for the C# Programmer

    - by mbcrump
    Are you a C# Programmer and can’t make it past a day without seeing or hearing someone mention F#?  Today, I’m going to walk you through your first F# application and give you a brief introduction to the language. Sit back this will only take about 20 minutes. Introduction Microsoft's F# programming language is a functional language for the .NET framework that was originally developed at Microsoft Research Cambridge by Don Syme. In October 2007, the senior vice president of the developer division at Microsoft announced that F# was being officially productized to become a fully supported .NET language and professional developers were hired to create a team of around ten people to build the product version. In September 2008, Microsoft released the first Community Technology Preview (CTP), an official beta release, of the F# distribution . In December 2008, Microsoft announced that the success of this CTP had encouraged them to escalate F# and it is now will now be shipped as one of the core languages in Visual Studio 2010 , alongside C++, C# 4.0 and VB. The F# programming language incorporates many state-of-the-art features from programming language research and ossifies them in an industrial strength implementation that promises to revolutionize interactive, parallel and concurrent programming. Advantages of F# F# is the world's first language to combine all of the following features: Type inference: types are inferred by the compiler and generic definitions are created automatically. Algebraic data types: a succinct way to represent trees. Pattern matching: a comprehensible and efficient way to dissect data structures. Active patterns: pattern matching over foreign data structures. Interactive sessions: as easy to use as Python and Mathematica. High performance JIT compilation to native code: as fast as C#. Rich data structures: lists and arrays built into the language with syntactic support. Functional programming: first-class functions and tail calls. Expressive static type system: finds bugs during compilation and provides machine-verified documentation. Sequence expressions: interrogate huge data sets efficiently. Asynchronous workflows: syntactic support for monadic style concurrent programming with cancellations. Industrial-strength IDE support: multithreaded debugging, and graphical throwback of inferred types and documentation. Commerce friendly design and a viable commercial market. Lets try a short program in C# then F# to understand the differences. Using C#: Create a variable and output the value to the console window: Sample Program. using System;   namespace ConsoleApplication9 {     class Program     {         static void Main(string[] args)         {             var a = 2;             Console.WriteLine(a);             Console.ReadLine();         }     } } A breeze right? 14 Lines of code. We could have condensed it a bit by removing the “using” statment and tossing the namespace. But this is the typical C# program. Using F#: Create a variable and output the value to the console window: To start, open Visual Studio 2010 or Visual Studio 2008. Note: If using VS2008, then please download the SDK first before getting started. If you are using VS2010 then you are already setup and ready to go. So, click File-> New Project –> Other Languages –> Visual F# –> Windows –> F# Application. You will get the screen below. Go ahead and enter a name and click OK. Now, you will notice that the Solution Explorer contains the following: Double click the Program.fs and enter the following information. Hit F5 and it should run successfully. Sample Program. open System let a = 2        Console.WriteLine a As Shown below: Hmm, what? F# did the same thing in 3 lines of code. Show me the interactive evaluation that I keep hearing about. The F# development environment for Visual Studio 2010 provides two different modes of execution for F# code: Batch compilation to a .NET executable or DLL. (This was accomplished above). Interactive evaluation. (Demo is below) The interactive session provides a > prompt, requires a double semicolon ;; identifier at the end of a code snippet to force evaluation, and returns the names (if any) and types of resulting definitions and values. To access the F# prompt, in VS2010 Goto View –> Other Window then F# Interactive. Once you have the interactive window type in the following expression: 2+3;; as shown in the screenshot below: I hope this guide helps you get started with the language, please check out the following books for further information. F# Books for further reading   Foundations of F# Author: Robert Pickering An introduction to functional programming with F#. Including many samples, this book walks through the features of the F# language and libraries, and covers many of the .NET Framework features which can be leveraged with F#.       Functional Programming for the Real World: With Examples in F# and C# Authors: Tomas Petricek and Jon Skeet An introduction to functional programming for existing C# developers written by Tomas Petricek and Jon Skeet. This book explains the core principles using both C# and F#, shows how to use functional ideas when designing .NET applications and presents practical examples such as design of domain specific language, development of multi-core applications and programming of reactive applications.
