  • Do you think functional language is good for applications that have a lot of business rules but very

    - by StackUnderflow
    I am convinced that functional programming is an excellent choice when it comes to applications that require a lot of computation (data mining, AI, nlp etc). But is it wise to use functional programming for a typical enterprise application where there are a lot of business rules but not much in terms of computation? Please disregard the fact that there are very few people using functional programming and that it's kind of tough. Thanks

  • Class-Level Model Validation with EF Code First and ASP.NET MVC 3

    - by ScottGu
    Earlier this week the data team released the CTP5 build of the new Entity Framework Code-First library.  In my blog post a few days ago I talked about a few of the improvements introduced with the new CTP5 build.  Automatic support for enforcing DataAnnotation validation attributes on models was one of the improvements I discussed.  It provides a pretty easy way to enable property-level validation logic within your model layer. You can apply validation attributes like [Required], [Range], and [RegularExpression] – all of which are built-into .NET 4 – to your model classes in order to enforce that the model properties are valid before they are persisted to a database.  You can also create your own custom validation attributes (like this cool [CreditCard] validator) and have them be automatically enforced by EF Code First as well.  This provides a really easy way to validate property values on your models.  I showed some code samples of this in action in my previous post. Class-Level Model Validation using IValidatableObject DataAnnotation attributes provides an easy way to validate individual property values on your model classes.  Several people have asked - “Does EF Code First also support a way to implement class-level validation methods on model objects, for validation rules than need to span multiple property values?”  It does – and one easy way you can enable this is by implementing the IValidatableObject interface on your model classes. IValidatableObject.Validate() Method Below is an example of using the IValidatableObject interface (which is built-into .NET 4 within the System.ComponentModel.DataAnnotations namespace) to implement two custom validation rules on a Product model class.  The two rules ensure that: New units can’t be ordered if the Product is in a discontinued state New units can’t be ordered if there are already more than 100 units in stock We will enforce these business rules by implementing the IValidatableObject interface on our Product class, and by implementing its Validate() method like so: The IValidatableObject.Validate() method can apply validation rules that span across multiple properties, and can yield back multiple validation errors. Each ValidationResult returned can supply both an error message as well as an optional list of property names that caused the violation (which is useful when displaying error messages within UI). Automatic Validation Enforcement EF Code-First (starting with CTP5) now automatically invokes the Validate() method when a model object that implements the IValidatableObject interface is saved.  You do not need to write any code to cause this to happen – this support is now enabled by default. This new support means that the below code – which violates one of our above business rules – will automatically throw an exception (and abort the transaction) when we call the “SaveChanges()” method on our Northwind DbContext: In addition to reactively handling validation exceptions, EF Code First also allows you to proactively check for validation errors.  Starting with CTP5, you can call the “GetValidationErrors()” method on the DbContext base class to retrieve a list of validation errors within the model objects you are working with.  GetValidationErrors() will return a list of all validation errors – regardless of whether they are generated via DataAnnotation attributes or by an IValidatableObject.Validate() implementation.  Below is an example of proactively using the GetValidationErrors() method to check (and handle) errors before trying to call SaveChanges(): ASP.NET MVC 3 and IValidatableObject ASP.NET MVC 2 included support for automatically honoring and enforcing DataAnnotation attributes on model objects that are used with ASP.NET MVC’s model binding infrastructure.  ASP.NET MVC 3 goes further and also honors the IValidatableObject interface.  This combined support for model validation makes it easy to display appropriate error messages within forms when validation errors occur.  To see this in action, let’s consider a simple Create form that allows users to create a new Product: We can implement the above Create functionality using a ProductsController class that has two “Create” action methods like below: The first Create() method implements a version of the /Products/Create URL that handles HTTP-GET requests - and displays the HTML form to fill-out.  The second Create() method implements a version of the /Products/Create URL that handles HTTP-POST requests - and which takes the posted form data, ensures that is is valid, and if it is valid saves it in the database.  If there are validation issues it redisplays the form with the posted values.  The razor view template of our “Create” view (which renders the form) looks like below: One of the nice things about the above Controller + View implementation is that we did not write any validation logic within it.  The validation logic and business rules are instead implemented entirely within our model layer, and the ProductsController simply checks whether it is valid (by calling the ModelState.IsValid helper method) to determine whether to try and save the changes or redisplay the form with errors. The Html.ValidationMessageFor() helper method calls within our view simply display the error messages our Product model’s DataAnnotations and IValidatableObject.Validate() method returned.  We can see the above scenario in action by filling out invalid data within the form and attempting to submit it: Notice above how when we hit the “Create” button we got an error message.  This was because we ticked the “Discontinued” checkbox while also entering a value for the UnitsOnOrder (and so violated one of our business rules).  You might ask – how did ASP.NET MVC know to highlight and display the error message next to the UnitsOnOrder textbox?  It did this because ASP.NET MVC 3 now honors the IValidatableObject interface when performing model binding, and will retrieve the error messages from validation failures with it. The business rule within our Product model class indicated that the “UnitsOnOrder” property should be highlighted when the business rule we hit was violated: Our Html.ValidationMessageFor() helper method knew to display the business rule error message (next to the UnitsOnOrder edit box) because of the above property name hint we supplied: Keeping things DRY ASP.NET MVC and EF Code First enables you to keep your validation and business rules in one place (within your model layer), and avoid having it creep into your Controllers and Views.  Keeping the validation logic in the model layer helps ensure that you do not duplicate validation/business logic as you add more Controllers and Views to your application.  It allows you to quickly change your business rules/validation logic in one single place (within your model layer) – and have all controllers/views across your application immediately reflect it.  This help keep your application code clean and easily maintainable, and makes it much easier to evolve and update your application in the future. Summary EF Code First (starting with CTP5) now has built-in support for both DataAnnotations and the IValidatableObject interface.  This allows you to easily add validation and business rules to your models, and have EF automatically ensure that they are enforced anytime someone tries to persist changes of them to a database.  ASP.NET MVC 3 also now supports both DataAnnotations and IValidatableObject as well, which makes it even easier to use them with your EF Code First model layer – and then have the controllers/views within your web layer automatically honor and support them as well.  This makes it easy to build clean and highly maintainable applications. You don’t have to use DataAnnotations or IValidatableObject to perform your validation/business logic.  You can always roll your own custom validation architecture and/or use other more advanced validation frameworks/patterns if you want.  But for a lot of applications this built-in support will probably be sufficient – and provide a highly productive way to build solutions. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Windows explorer locks files

    - by John Prince
    I'm using Office 2010 & Windows 7 Home Premium 64-bit. My problem starts when I attempt to save e-mail messages to my PC that I have received via Outlook (my ISP is Comcast). I'm using the default .msg file extension option when I attempt to save these e-mails. The resultant files are locked and do not show the normal "envelope" icon. Instead, it’s a “blank page” icon with the right upper corner folded in. These files refuse to open either by double clicking on them or right clicking and trying to open them with Outlook. And when I return to Outlook, I discover that Outlook is now hung up and I have to close it via the Task Manager. To make matters worse, I’ve also discovered that every e-mail message that I've saved on my PC over the years has also somehow become locked and their original "envelope" icon has been replaced with the "blank page" icon. I found and installed an application called LockHunter. As a result, when I right click on a saved and locked e-mail message, I’ve given an option to find out what's locking it. Each time I'm told that the culprit is Windows explorer.exe. When I unlock the file the normal envelope icon is sometimes displayed (but not always) but at least the file can then be opened. But the file is still “squirrely” as it can’t be moved or saved to a folder until it’s unlocked again. On this second attempt, LockHunter says it’s now locked by Outlook.exe. By the way, I don't have this issue when I save Word, Excel & PowerPoint files; only with Outlook. I've exhausted every remedy that I can think of including: making sure that the file and folder options are checked to always show icons and not thumbnails; running the Windows 7 & Office 2010 repair options which find nothing amiss; running a complete system scan with Windows Malicious Software Removal Tool with negative results; verifying that Outlook is the default for opening e-mails; updating all of my applications via Secunia Personal Software Inspector; uninstalling every application that I felt was unnecessary; doing a registry cleanup via CC Cleaner; having Windows Security Essentials always on (it did find one Java Trojan recently which was quarantined and then deleted); uninstalling a bunch of non-Microsoft shell extensions; and deactivating all of the Outlook Add-ins and then re-activating each one. None of this solves the problem. I’d welcome any advice on how to resolve this.

  • Creating floppy drive special devices under Quantal

    - by JCCyC
    First, I'd like for the various special devices for different floppy capacities (like /dev/fd0u720 etc.) to be available. I tried to adapt some udev rules I found online. I tried this, which I saved as /etc/udev/rules.d/70-persistent-floppy.rules: # change floppy device ownership and permissions # default permissions are 640, which prevents group users from having write access # first fix primary devices (/dev/fd0, /dev/fd1, etc.) # also change group ownership from disk to floppy SUBSYSTEM=="block", KERNEL=="fd[0-9]*", GROUP="floppy", MODE="0660" # next recreate secondary devices (/dev/fd0u720, /dev/fd0u1440, etc.) SUBSYSTEM=="block", KERNEL=="fd[0-9]*", ACTION=="add", RUN+="create_floppy_devices -c -t $attr{cmos} -m %M -M 0660 -G floppy $root/%k" But to no avail. It seems the create_floppy_devices script isn't provided with 12.10. How do I obtain it? Second: I'm using MATE, and whenever I log in I get a message box saying it tried to mount the drive but failed. How do I disable this? Third (which is probably related to the second): Whenever there's a disk in the drive, the motor won't stop spinning. If I do a mdir of it, after it returns, the motor stops, and then starts again. I suspect there's some process in MATE doing this. UPDATE: For CentOS 6 (who does have a create_floppy_devices program) the following rules file worked. Saved as /etc/udev/rules.d/98-floppy.rules: # change floppy device ownership and permissions # default permissions are 640, which prevents group users from having write access # first fix primary devices (/dev/fd0, /dev/fd1, etc.) # also change group ownership from disk to floppy KERNEL=="fd[0-9]*", GROUP="floppy", MODE="0660" # next recreate secondary devices (/dev/fd0u720, /dev/fd0u1440, etc.) # drive A: is type 4 (1.44MB) - add other lines for other drives KERNEL=="fd0*", ACTION=="add", RUN+="/lib/udev/create_floppy_devices -c -t 4 -m %M -M 0660 -G floppy $root/%k"

  • Why are .NET app.config load rules different for win2k3?

    - by Dan
    ...and are there any other caveat for other platforms? I create an app.config for a win forms project, for example Application.exe. By default I expect that at runtime my application is going to look for a file called Application.exe.config. But there seem to be exceptions to this, for example in a Windows Server 2003 environment an app will look for Application.config. The full path of the config file being searched for is different in Windows Server 2003, why is this? Where is the definition for these cosmic app.config loading rules?

  • What are the rules for Javascript's automatic semicolon insertion?

    - by T.R.
    Well, first I should probably ask if this is browser dependent. I've read that if an invalid token is found, but the section of code is valid until that invalid token, a semicolon is inserted before the token if it is preceded by a line break. However, the common example cited for bugs caused by semicolon insertion is: return _a+b; which doesn't seem to follow this rule, since _a would be a valid token. On the other hand, breaking up call chains works as expected: $('#myButton') .click(function(){alert("Hello!")}); Does anyone have a more in-depth description of the rules?

  • What are some best practises and "rules of thumb" for creating database indexes?

    - by Ash
    I have an app, which cycles through a huge number of records in a database table and performs a number of SQL and .Net operations on records within that database (currently I am using Castle.ActiveRecord on PostgreSQL). I added some basic btree indexes on a couple of the feilds, and as you would expect, the peformance of the SQL operations increased substantially. Wanting to make the most of dbms performance I want to make some better educated choices about what I should index on all my projects. I understand that there is a detrement to performance when doing inserts (as the database needs to update the index, as well as the data), but what suggestions and best practices should I consider with creating database indexes? How do I best select the feilds/combination of fields for a set of database indexes (rules of thumb)? Also, how do I best select which index to use as a clustered index? And when it comes to the access method, under what conditions should I use a btree over a hash or a gist or a gin (what are they anyway?).

  • What are the precise rules/PHP function for encoding strings into POST arrays?

    - by AlexeyMK
    Greetings, Just getting into PHP web development. I've got an HTML form where a user checks some series of dynamically-generated checkboxes, and submits via POST. On the PHP side, I want to check which of the check-boxes were clicked. I have an array $full_list, and am doing something like $selected_checkboxes = array_filter($full_list, function($item) { array_key_exists($item, $_POST); } I run into problems when a list item is named, for example "Peanut Butter", since in the POST array it is named "Peanut_Butter". I could certainly just str_replace " " with "_" before checking array_key_exists, but I imagine that there is a more fundamental encoding problem here; specifically, I'm not sure of exactly what layer transforms normal strings in HTML Forms (value="Peanut Butter") into "Peanut_Butter". So: what layer is responsible for this conversion? Is it the browser? what are the exact conversion rules, and is there a PHP function out there that will replicate that exact conversion? Thanks!

  • How to name an event handler of a private variable in Vb.Net following FxCop rules and Vb.Net standa

    - by SoMoS
    Hello, On one side, in Vb.Net when you add an event handler to an object the created method is named: <NameOfTheObject>_<NameOfTheMethod>. As I like to have consistent syntax I always follow this rule when creating event handlers by hand. On the other side when I create private variables I prefix them with m_ as this is a common thing used by the community, in C# people use to put _ at the beginning of a variable but this is no CLS compliant. At the end, when I create event handlers for events raised by private variables I end with Subs like m_myVariable_MyEvent. Code Analysis (Fx Cop) is complainig about this way of naming because the method does not start with uppercase and because the _, so the question is: What naming standards do you follow when creating event handlers by hand that follow the Fxcop rules if any? Thanks in advance.

  • CakePHP: Same model, set up per form validation rules?

    - by mwaterous
    I have a single model in CakePHP that has multiple forms on different pages of the site that I would like to validate differently even where the field name is the same - I have discovered that you can set 'on' to create|update which has been a handy discovery but I am wondering if there is any other way of explicitly declaring rules based on the form that was submitted? Just to rephrase for clarity, form a and form b contain fields of the same name, but if form a is submitted the fields in question should be validated differently than if they were submitted from form b. Possible?

  • Doesn’t <asp:A runat=”server” B=”someValue” … /> syntax violate one of the basic rules in C# languag

    - by AspOnMyNet
    Assuming server control of type A has a protected member M, then we are also able to access A.M via declaring control tag A on some aspx page: <asp:A runat=”server” M=”someValue” … /> But isn’t one of the rules in C# that protected members of class A can only be accessed from A and from classes derived from A? So doesn’t the ability to access member A.M via <asp:A M=”someValue” … /> syntax violate this rule, since we are basically accessing A.M from a class ( which is automatically generated aspx class ) not derived from A?!

  • How to learn programming language (syntax rules, etc.) and remember easily? [closed]

    - by user239522
    I'm new to programming, and I always have a so call difficulty, that is, I always tend to forget the thing (syntax, rules, name, definition or anyting) of a programming language I've learnt. And I personally do feel that the way I learn it is wrong. Here is my method. Everyday I will spend approximately 1 or 2 hours on a programming e-book. I just follow the syllabus and teaching inside the books, of course I have try to code myself, alter the code inside the book, and did the exercises available. But everytime right after I finish a chapter and advanced myself to third or fourth chapter, I will forgot something I learnt in the first chapter. Is it the method I use wrong? Does learning through reading and coding not enough? Do I need to everytime make a small note (mind map for example) of things I've learnt by hand writing? Or do I sometime need to try coding using a pencil and a book, but not a computer?

  • Autoscaling in a modern world&hellip;. Part 3

    - by Steve Loethen
    The Wasabi Hands on Labs give you a good look at the basic mechanics, but I don’t find the setup too practical.  Using a local console application to host the Autoscaler and rules files is probably the (IMHO) least likely architecture.  Far more common would be hosting in a service on premise (if you want to have the Autoscaler local) or most likely, host it in a Azure role of it’s own.  I chose to go the Azure route. First step was to get the rules.xml and the services.xml files into the cloud.  I tend to be a “one step at a time” sort of guy, so running the console application with the rules sitting in a Azure hosted set of blobs seemed to be the logical first step.  Here are the steps: 1) Create a container in the storage account you wish to use.  Name does not matter, you will get a chance to set the container name (as well as the file names) in the app.config 2) Copy the two files from where you created them to your  container.  I used the same files I had locally.  I made the container public to eliminate security issues, but in the final application, a bit of security needs to be applied (one problem at a time).  The content type was set to text/xml.  I found one reference claiming the importance of this step, and it makes sense. 3) Adjust the app.config to set the location of the files.  This will let you set all the storage account and key information needed to reach into the cloud form your console application.  The sections of your app.config will look like this: <rulesStores> <add name="Blob Rules Store" type="Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.Rules.Configuration.BlobXmlFileRulesStore, Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling, Version=5.0.1118.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" blobContainerName="[ContainerName]" blobName="rules.xml" storageAccount="DefaultEndpointsProtocol=https;AccountName=[StorageAccount];AccountKey=[AccountKey]" monitoringRate="00:00:30" certificateThumbprint="" certificateStoreLocation="LocalMachine" checkCertificateValidity="false" /> </rulesStores> <serviceInformationStores> <add name="Blob Service Information Store" type="Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling.ServiceModel.Configuration.BlobXmlFileServiceInformationStore, Microsoft.Practices.EnterpriseLibrary.WindowsAzure.Autoscaling, Version=5.0.1118.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" blobContainerName="[ContainerName]" blobName="services.xml" storageAccount="DefaultEndpointsProtocol=https;AccountName=[StorageAccount];AccountKey=[AccountKey]" monitoringRate="00:00:30" certificateThumbprint="" certificateStoreLocation="LocalMachine" checkCertificateValidity="false" /> </serviceInformationStores> Once I had the files up in the sky, I renamed the local copies to just to make my self feel better about the application using the correct set of rules and services.  Deploy the web role to the cloud.  Once it is up and running, start the console application.  You should find the application scales up and down in response to the buttons on the web site.  Tune in next time for moving the hosting of the Autoscaler to a worker role, discussions on getting the logging information into diagnostics into storage, and a set of discussions about certs and how they play a role.

  • NDepend 4.0 Released

    - by Anthony Trudeau
    Last week version 4.0 of NDepend was released.  NDepend is a Visual Studio add-in designed for intense code analysis with the goal of high quality code.  A month ago I wrapped up my evaluation of the previous version of NDepend. The new version contains many minor changes, several bug fixes, and adds about 50 new code rules.  The version also adds support for Visual Studio 11, .NET Framework 4.5, and SilverLight 5.0.  But, the biggest change was the shift from CQL to CQLinq. Introducing CQLinq The latest version replaces the CQL rules language with CQLinq (CQL is still an option although the editor is buried).  As you might guess CQLinq is a flavor of Linq designed specifically for the code rules. The best way to illustrate the differences is with an example.  I used the following CQL example in Part 3 of my review: WARN IF Count > 0 IN SELECT TYPES WHERE IsInterface AND !NameLike “I” This same query looks like this when implemented in CQLinq: warnif count > 0 from t in Types where t.IsInterface == true && !t.NameLike(“I”) select t I like the syntax and it is a natural fit, but I found writing the queries frustrating in the Queries and Rules Edit window.  The Queries and Rules Edit window replaces the CQL Query Edit window.  The new editor has the same style of Intellisense as the previous editor.  However, it has a few annoyances.  The error indicator is a red block.  It has the tendency of obscuring your cursor.  Additionally, writing CQLing queries is like writing plain old Linq queries, so the fact that the editor uses Enter to select from Intellisense instead of Tab is jarring.  These issues can be an obstacle to writing queries quickly.CQLinq makes it possible to write rules that weren't possible before.  Additionally, a JustMyCode domain is now possible making it easy to eliminate generated code from the analysis.Should you Buy? I recommend NDepend overall.  It has some rough points for me that I have detailed in my earlier evaluation (starting here).  But, it’s definitely worth the money.  The bigger question is: should I pay for the upgrade to 4.0?  At this point I’m on the fence, but I would go for it if you need support for Visual Studio 2011, .NET Framework 4.5, or Silverlight 5.0; or if you need one of the many rules that weren't possible before CQLinq. Disclaimer: Patrick Smacchia contacted me about reviewing NDepend. I received a free license in return for sharing my experiences and talking about the capabilities of the add-in on this site. There is no expectation of a positive review elicited from the author of NDepend. Resources: NDepend Release Notes

  • The Politics of Junk Filtering

    - by mikef
    If the national postal service, such as the Royal Mail in the UK, were to go through your letters and throw away all the stuff it considered to be junk instead of delivering it to you, you might be rather pleased until you discovered that it took a too liberal decision about what was junk. Catalogs you'd asked for? Junk! Requests from charities? Who needs them! Parcels from competing carriers? Toss them away! The possibility for abuse for an agency that was in a monopolistic position is just too scary to tolerate. After all, the postal service could charge 'consultancy fees' to any sender who wanted to guarantee that his stuff got delivered, or they could even farm this out to other companies. Because Microsoft Outlook is just about the only email client used by the international business community in the west, its' SPAM filter is the final arbiter as to what gets read. My Outlook 2007, set to the default settings, junks all the perfectly innocent email newsletters that I subscribe to. Whereas Google Mail, Yahoo, and LIVE are all pretty accurate in detecting spam, Outlook makes all sorts of silly mistakes. The documentation speaks techno-babble about 'advanced heuristics', but the result boils down to an inaccurate mess. The more that Microsoft fiddles with it, the stickier the mess. To make matters worse, it still lets through obvious spam. The filter is occasionally updated along with other automatic 'security' updates you opt for automatic updates. As an editor for a popular online publication that provides a newsletter service, this is an obvious source of frustration. We follow all the best-practices we know about. We ensure that it is a trivial task to opt out of receiving it. We format the newsletter to the requirements of the Service Providers. We follow up, and resolve, every complaint. As a result, it gets delivered. It is galling to discover that, after all that effort, Outlook then often judges the contents to be junk on a whim, so you don't get to see it. A few days ago, Microsoft published the PST file format specification, under pressure from a European Union interoperability investigation by ECIS (the European Committee for Interoperable Systems). The objective was that other applications could then access existing PST files so as to migrate from existing Outlook installations to other solutions. Joaquín Almunia, the current competition commissioner, should now turn his attention to the more subtle problems of Microsoft Outlook. The Junk problem seems to have come from clumsy implementation of client-side spam filtering rather than from deliberate exploitation of a monopoly on the desktop email client for businesses, but it is a growing problem nonetheless.

  • It it possible to have multiple ReWrite rules that all do the same Action, for an IIS7.5 webserver?

    I've got rewrite module working great for my IIS7.5 site. Now, I wish to add a number of urls that all goto an HTTP 410-Gone status. Eg. <rule name="Old Site = image1" patternSyntax="ExactMatch" stopProcessing="true"> <match url="image/loading_large.gif"/> <match url="image/aaa.gif"/> <match url="image/bbb.gif"/> <match url="image/ccc.gif"/> <action type="CustomResponse" statusCode="410" statusReason="Gone" statusDescription="The requested resource is no longer available" /> </rule> but that's invalid - the website doesn't start saying there's a rewrite config error. Is there another way I can do this? I don't particularly want define a single URL and ACTION for each url.

  • Fail2Ban adds iptable rules but they are not working?

    - by EApubs
    Fail2Ban just blocked my IP for 3 SSH attempts. It added the iptables rule and I can see it using the "sudo iptables -L -n" command. But I can still access the site and login through SSH! What might be the problem? Is it because im using CloudFlare? I have set Nginx to write the real IPs to the access logs instead of the Cloud Flare IP. Isn't it enough?
