• ASPNET WebAPI REST Guidance

  - by JoshReuben

  ASP.NET Web API is an ideal platform for building RESTful applications on the .NET Framework. While I may be more partial to NodeJS these days, there is no denying that WebAPI is a well engineered framework. What follows is my investigation of how to leverage WebAPI to construct a RESTful frontend API.   The Advantages of REST Methodology over SOAP Simpler API for CRUD ops Standardize Development methodology - consistent and intuitive Standards based à client interop Wide industry adoption, Ease of use à easy to add new devs Avoid service method signature blowout Smaller payloads than SOAP Stateless à no session data means multi-tenant scalability Cache-ability Testability   General RESTful API Design Overview · utilize HTTP Protocol - Usage of HTTP methods for CRUD, standard HTTP response codes, common HTTP headers and Mime Types · Resources are mapped to URLs, actions are mapped to verbs and the rest goes in the headers. · keep the API semantic, resource-centric – A RESTful, resource-oriented service exposes a URI for every piece of data the client might want to operate on. A REST-RPC Hybrid exposes a URI for every operation the client might perform: one URI to fetch a piece of data, a different URI to delete that same data. utilize Uri to specify CRUD op, version, language, output format: http://api.MyApp.com/{ver}/{lang}/{resource_type}/{resource_id}.{output_format}?{key&filters} · entity CRUD operations are matched to HTTP methods: · Create - POST / PUT · Read – GET - cacheable · Update – PUT · Delete - DELETE · Use Uris to represent a hierarchies - Resources in RESTful URLs are often chained · Statelessness allows for idempotency – apply an op multiple times without changing the result. POST is non-idempotent, the rest are idempotent (if DELETE flags records instead of deleting them). · Cache indication - Leverage HTTP headers to label cacheable content and indicate the permitted duration of cache · PUT vs POST - The client uses PUT when it determines which URI (Id key) the new resource should have. The client uses POST when the server determines they key. PUT takes a second param – the id. POST creates a new resource. The server assigns the URI for the new object and returns this URI as part of the response message. Note: The PUT method replaces the entire entity. That is, the client is expected to send a complete representation of the updated product. If you want to support partial updates, the PATCH method is preferred DELETE deletes a resource at a specified URI – typically takes an id param · Leverage Common HTTP Response Codes in response headers 200 OK: Success 201 Created - Used on POST request when creating a new resource. 304 Not Modified: no new data to return. 400 Bad Request: Invalid Request. 401 Unauthorized: Authentication. 403 Forbidden: Authorization 404 Not Found – entity does not exist. 406 Not Acceptable – bad params. 409 Conflict - For POST / PUT requests if the resource already exists. 500 Internal Server Error 503 Service Unavailable · Leverage uncommon HTTP Verbs to reduce payload sizes HEAD - retrieves just the resource meta-information. OPTIONS returns the actions supported for the specified resource. PATCH - partial modification of a resource. · When using PUT, POST or PATCH, send the data as a document in the body of the request. Don't use query parameters to alter state. · Utilize Headers for content negotiation, caching, authorization, throttling o Content Negotiation – choose representation (e.g. JSON or XML and version), language & compression. Signal via RequestHeader.Accept & ResponseHeader.Content-Type Accept: application/json;version=1.0 Accept-Language: en-US Accept-Charset: UTF-8 Accept-Encoding: gzip o Caching - ResponseHeader: Expires (absolute expiry time) or Cache-Control (relative expiry time) o Authorization - basic HTTP authentication uses the RequestHeader.Authorization to specify a base64 encoded string "username:password". can be used in combination with SSL/TLS (HTTPS) and leverage OAuth2 3rd party token-claims authorization. Authorization: Basic sQJlaTp5ZWFslylnaNZ= o Rate Limiting - Not currently part of HTTP so specify non-standard headers prefixed with X- in the ResponseHeader. X-RateLimit-Limit: 10000 X-RateLimit-Remaining: 9990 · HATEOAS Methodology - Hypermedia As The Engine Of Application State – leverage API as a state machine where resources are states and the transitions between states are links between resources and are included in their representation (hypermedia) – get API metadata signatures from the response Link header - in a truly REST based architecture any URL, except the initial URL, can be changed, even to other servers, without worrying about the client. · error responses - Do not just send back a 200 OK with every response. Response should consist of HTTP error status code (JQuery has automated support for this), A human readable message , A Link to a meaningful state transition , & the original data payload that was problematic. · the URIs will typically map to a server-side controller and a method name specified by the type of request method. Stuff all your calls into just four methods is not as crazy as it sounds. · Scoping - Path variables look like you’re traversing a hierarchy, and query variables look like you’re passing arguments into an algorithm · Mapping URIs to Controllers - have one controller for each resource is not a rule – can consolidate - route requests to the appropriate controller and action method · Keep URls Consistent - Sometimes it’s tempting to just shorten our URIs. not recommend this as this can cause confusion · Join Naming – for m-m entity relations there may be multiple hierarchy traversal paths · Routing – useful level of indirection for versioning, server backend mocking in development ASPNET WebAPI Considerations ASPNET WebAPI implements a lot (but not all) RESTful API design considerations as part of its infrastructure and via its coding convention. Overview When developing an API there are basically three main steps: 1. Plan out your URIs 2. Setup return values and response codes for your URIs 3. Implement a framework for your API.   Design · Leverage Models MVC folder · Repositories – support IoC for tests, abstraction · Create DTO classes – a level of indirection decouples & allows swap out · Self links can be generated using the UrlHelper · Use IQueryable to support projections across the wire · Models can support restful navigation properties – ICollection<T> · async mechanism for long running ops - return a response with a ticket – the client can then poll or be pushed the final result later. · Design for testability - Test using HttpClient , JQuery ( $.getJSON , $.each) , fiddler, browser debug. Leverage IDependencyResolver – IoC wrapper for mocking · Easy debugging - IE F12 developer tools: Network tab, Request Headers tab     Routing · HTTP request method is matched to the method name. (This rule applies only to GET, POST, PUT, and DELETE requests.) · {id}, if present, is matched to a method parameter named id. · Query parameters are matched to parameter names when possible · Done in config via Routes.MapHttpRoute – similar to MVC routing · Can alternatively: o decorate controller action methods with HttpDelete, HttpGet, HttpHead,HttpOptions, HttpPatch, HttpPost, or HttpPut., + the ActionAttribute o use AcceptVerbsAttribute to support other HTTP verbs: e.g. PATCH, HEAD o use NonActionAttribute to prevent a method from getting invoked as an action · route table Uris can support placeholders (via curly braces{}) – these can support default values and constraints, and optional values · The framework selects the first route in the route table that matches the URI. Response customization · Response code: By default, the Web API framework sets the response status code to 200 (OK). But according to the HTTP/1.1 protocol, when a POST request results in the creation of a resource, the server should reply with status 201 (Created). Non Get methods should return HttpResponseMessage · Location: When the server creates a resource, it should include the URI of the new resource in the Location header of the response. public HttpResponseMessage PostProduct(Product item) {     item = repository.Add(item);     var response = Request.CreateResponse<Product>(HttpStatusCode.Created, item);     string uri = Url.Link("DefaultApi", new { id = item.Id });     response.Headers.Location = new Uri(uri);     return response; } Validation · Decorate Models / DTOs with System.ComponentModel.DataAnnotations properties RequiredAttribute, RangeAttribute. · Check payloads using ModelState.IsValid · Under posting – leave out values in JSON payload à JSON formatter assigns a default value. Use with RequiredAttribute · Over-posting - if model has RO properties à use DTO instead of model · Can hook into pipeline by deriving from ActionFilterAttribute & overriding OnActionExecuting Config · Done in App_Start folder > WebApiConfig.cs – static Register method: HttpConfiguration param: The HttpConfiguration object contains the following members. Member Description DependencyResolver Enables dependency injection for controllers. Filters Action filters – e.g. exception filters. Formatters Media-type formatters. by default contains JsonFormatter, XmlFormatter IncludeErrorDetailPolicy Specifies whether the server should include error details, such as exception messages and stack traces, in HTTP response messages. Initializer A function that performs final initialization of the HttpConfiguration. MessageHandlers HTTP message handlers - plug into pipeline ParameterBindingRules A collection of rules for binding parameters on controller actions. Properties A generic property bag. Routes The collection of routes. Services The collection of services. · Configure JsonFormatter for circular references to support links: PreserveReferencesHandling.Objects Documentation generation · create a help page for a web API, by using the ApiExplorer class. · The ApiExplorer class provides descriptive information about the APIs exposed by a web API as an ApiDescription collection · create the help page as an MVC view public ILookup<string, ApiDescription> GetApis()         {             return _explorer.ApiDescriptions.ToLookup(                 api => api.ActionDescriptor.ControllerDescriptor.ControllerName); · provide documentation for your APIs by implementing the IDocumentationProvider interface. Documentation strings can come from any source that you like – e.g. extract XML comments or define custom attributes to apply to the controller [ApiDoc("Gets a product by ID.")] [ApiParameterDoc("id", "The ID of the product.")] public HttpResponseMessage Get(int id) · GlobalConfiguration.Configuration.Services – add the documentation Provider · To hide an API from the ApiExplorer, add the ApiExplorerSettingsAttribute Plugging into the Message Handler pipeline · Plug into request / response pipeline – derive from DelegatingHandler and override theSendAsync method – e.g. for logging error codes, adding a custom response header · Can be applied globally or to a specific route Exception Handling · Throw HttpResponseException on method failures – specify HttpStatusCode enum value – examine this enum, as its values map well to typical op problems · Exception filters – derive from ExceptionFilterAttribute & override OnException. Apply on Controller or action methods, or add to global HttpConfiguration.Filters collection · HttpError object provides a consistent way to return error information in the HttpResponseException response body. · For model validation, you can pass the model state to CreateErrorResponse, to include the validation errors in the response public HttpResponseMessage PostProduct(Product item) {     if (!ModelState.IsValid)     {         return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState); Cookie Management · Cookie header in request and Set-Cookie headers in a response - Collection of CookieState objects · Specify Expiry, max-age resp.Headers.AddCookies(new CookieHeaderValue[] { cookie }); Internet Media Types, formatters and serialization · Defaults to application/json · Request Accept header and response Content-Type header · determines how Web API serializes and deserializes the HTTP message body. There is built-in support for XML, JSON, and form-urlencoded data · customizable formatters can be inserted into the pipeline · POCO serialization is opt out via JsonIgnoreAttribute, or use DataMemberAttribute for optin · JSON serializer leverages NewtonSoft Json.NET · loosely structured JSON objects are serialzed as JObject which derives from Dynamic · to handle circular references in json: json.SerializerSettings.PreserveReferencesHandling =    PreserveReferencesHandling.All à {"$ref":"1"}. · To preserve object references in XML [DataContract(IsReference=true)] · Content negotiation Accept: Which media types are acceptable for the response, such as “application/json,” “application/xml,” or a custom media type such as "application/vnd.example+xml" Accept-Charset: Which character sets are acceptable, such as UTF-8 or ISO 8859-1. Accept-Encoding: Which content encodings are acceptable, such as gzip. Accept-Language: The preferred natural language, such as “en-us”. o Web API uses the Accept and Accept-Charset headers. (At this time, there is no built-in support for Accept-Encoding or Accept-Language.) · Controller methods can take JSON representations of DTOs as params – auto-deserialization · Typical JQuery GET request: function find() {     var id = $('#prodId').val();     $.getJSON("api/products/" + id,         function (data) {             var str = data.Name + ': $' + data.Price;             $('#product').text(str);         })     .fail(         function (jqXHR, textStatus, err) {             $('#product').text('Error: ' + err);         }); }            · Typical GET response: HTTP/1.1 200 OK Server: ASP.NET Development Server/10.0.0.0 Date: Mon, 18 Jun 2012 04:30:33 GMT X-AspNet-Version: 4.0.30319 Cache-Control: no-cache Pragma: no-cache Expires: -1 Content-Type: application/json; charset=utf-8 Content-Length: 175 Connection: Close [{"Id":1,"Name":"TomatoSoup","Price":1.39,"ActualCost":0.99},{"Id":2,"Name":"Hammer", "Price":16.99,"ActualCost":10.00},{"Id":3,"Name":"Yo yo","Price":6.99,"ActualCost": 2.05}] True OData support · Leverage Query Options $filter, $orderby, $top and $skip to shape the results of controller actions annotated with the [Queryable]attribute. [Queryable]  public IQueryable<Supplier> GetSuppliers()  · Query: ~/Suppliers?$filter=Name eq ‘Microsoft’ · Applies the following selection filter on the server: GetSuppliers().Where(s => s.Name == “Microsoft”)  · Will pass the result to the formatter. · true support for the OData format is still limited - no support for creates, updates, deletes, $metadata and code generation etc · vnext: ability to configure how EditLinks, SelfLinks and Ids are generated Self Hosting no dependency on ASPNET or IIS: using (var server = new HttpSelfHostServer(config)) {     server.OpenAsync().Wait(); Tracing · tracability tools, metrics – e.g. send to nagios · use your choice of tracing/logging library, whether that is ETW,NLog, log4net, or simply System.Diagnostics.Trace. · To collect traces, implement the ITraceWriter interface public class SimpleTracer : ITraceWriter {     public void Trace(HttpRequestMessage request, string category, TraceLevel level,         Action<TraceRecord> traceAction)     {         TraceRecord rec = new TraceRecord(request, category, level);         traceAction(rec);         WriteTrace(rec); · register the service with config · programmatically trace – has helper extension methods: Configuration.Services.GetTraceWriter().Info( · Performance tracing - pipeline writes traces at the beginning and end of an operation - TraceRecord class includes aTimeStamp property, Kind property set to TraceKind.Begin / End Security · Roles class methods: RoleExists, AddUserToRole · WebSecurity class methods: UserExists, .CreateUserAndAccount · Request.IsAuthenticated · Leverage HTTP 401 (Unauthorized) response · [AuthorizeAttribute(Roles="Administrator")] – can be applied to Controller or its action methods · See section in WebApi document on "Claim-based-security for ASP.NET Web APIs using DotNetOpenAuth" – adapt this to STS.--> Web API Host exposes secured Web APIs which can only be accessed by presenting a valid token issued by the trusted issuer. http://zamd.net/2012/05/04/claim-based-security-for-asp-net-web-apis-using-dotnetopenauth/ · Use MVC membership provider infrastructure and add a DelegatingHandler child class to the WebAPI pipeline - http://stackoverflow.com/questions/11535075/asp-net-mvc-4-web-api-authentication-with-membership-provider - this will perform the login actions · Then use AuthorizeAttribute on controllers and methods for role mapping- http://sixgun.wordpress.com/2012/02/29/asp-net-web-api-basic-authentication/ · Alternate option here is to rely on MVC App : http://forums.asp.net/t/1831767.aspx/1

• Using telerik radGrid - how to set the Date format for autogenerated column in edit mode

  - by Mark Breen

  Hello All, Using VS2008, and Telerik radGrid version 2010.1.519.35 I have a about 50 DNN modules using telerik radgrid and I need to display my dates in dd/mm/yy format. It is possible to do this easily in view mode, but when I switch to edit mode, it is more of a struggle. I can write a snippit of code to reformat the displayed date values to dd/mm/yy, but for inserts the user must enter mm/dd/yy. IOW, I need to change the culture of the form to en-GB culture. In my DotnetNuke App, I have made a change to the web.config, but it still assumes en-US format. I am not sure whether I need to set this at web.config level, page level or at the column within the control. I am struggling with this for a month or more and any help would be appriciated, thanks Mark Breen Ireland BMW R80GS 1987

• Fluent NHibernate Map Enum as Lookup Table

  - by Jaimal Chohan

  I have the following (simplified) public enum Level { Bronze, Silver, Gold } public class Member { public virtual Level MembershipLevel { get; set; } } public class MemberMap : ClassMap<Member> { Map(x => x.MembershipLevel); } This creates a table with a column called MembershipLevel with the value as the Enum string value. What I want is for the entire Enum to be created as a lookup table, with the Membe table referencing this with the integer value as the FK. Also, I want to do this without bas***izing my model. Any ideas? [And I want time machine] [With 2 cup holders]

• any real MVC library in PHP (for GUI apps)

  - by mario

  I'm wondering if there are any abstraction frameworks for one of the PHP gui libraries. We have PHP-GTK, a PHP/Tk interface, and seemingly also PHP-QT. (Not tried any.) I know that writing against the raw Gtk+ interface in Python is just bearable, and it therefore seems not very enticing for PHP. I assume it's the same for Qt, and Tk is pretty low-level too. So I'm looking for something that provides a nicer object structure atop any of the three. Primarily TreeViews are always a chore and php-gtk callbacks are weird in PHP, so I'd like a simplification for that. If it eases adding the GUI/View atop my business logic without much control code, that might already help. And so since GUI apps are an area where MVC or MVP would actually make sense, I'd like to know if any library for that exists. Btw, recently rediscovered PHP interface preprocessor, but that's rather low-level and just provides a simple widget/interface abstraction for Gtk/ncurses/pdf/xhtml output.

• System calls on Windows

  - by b-gen-jack-o-neill

  Hi, I just want to ask, I know that standart system calls in Linux are done by int instruction pointing into Interrupt Vector Table. I assume this is similiar on Windows. But, how do you call some higher-level specific system routines? Such as how do you tell Windows to create a window? I know this is handled by the code in the dll, but what actually happend at assembler-instruction level? Does the routine in dll calls software interrupt by int instruction, or is there any different approach to handle this? Thanks.

  - by sah302

  I know this is almost duplicate of : http://stackoverflow.com/questions/1269706/the-error-login-failed-for-user-nt-authority-iusr-in-asp-net-and-sql-server-2 and http://stackoverflow.com/questions/97594/login-failed-for-user-username-system-data-sqlclient-sqlexception-with-linq-i but some things don't add up compared to other appliations on my server and I am not sure why. Boxes being used: Web Box SQL Box SQL Test Box My Application: I've got aASP.NET Web Application, which references a class library that uses LINQ-to-SQL. Connection string set up properly in the class library. As per http://stackoverflow.com/questions/97594/login-failed-for-user-username-system-data-sqlclient-sqlexception-with-linq-i I also added this connection string to the Web Application. The connection string uses SQL credentials as so (in both web app and class library): <add name="Namespace.My.MySettings.ConnectionStringProduction" connectionString="Data Source=(SQL Test Box);Initial Catalog=(db name);Persist Security Info=True;User ID=ID;Password=Password" providerName="System.Data.SqlClient" /> This connection confirmed as working via adding it to server explorer. This is the connection string my .dbml file is using. The problem: I get the following error: System.Data.SqlClient.SqlException: Login failed for user 'DOMAIN\MACHINENAME$'. Now referencing this http://stackoverflow.com/questions/1269706/the-error-login-failed-for-user-nt-authority-iusr-in-asp-net-and-sql-server-2 it says that's really the local network service and using any other non-domain name will not work. But I am confused because I've checked both SQL Box and SQL Test Box SQL Management Studio and both have NT AUTHORITY/NETWORK SERVICE under Security - Logins, at the database level, that isn't listed under Security - Users, but at the database level Security - Users I have the user displayed in the connection string. At NTFS level on web server, the permissions have NETWORK SERVICE has full control. The reason why I am confused is because I have many other web applications on my Web Server, that reference databases on both SQL Box and SQL Test Box, and they all work. But I cannot find a difference between them and my current application, other than I am using a class library. Will that matter? Checking NTFS permissions, setup of Security Logins at the server and databases levels, connection string and method of connecting (SQL Server credentials), and IIS application pool and other folder options, are all the same. Why do these applications work without adding the machinename$ to the permissions of either of my SQL boxes? But that is what the one link is telling me to do to fix this problem.

• Stepping over method without symbols - How to step into?

  - by joedotnot

  Using Visual Studio 2008 SP1 and a VB.NET project; I have some code which i cannot step into. The Immediate Window shows the message "Stepping over method without symbols 'Some.Namespace.Here'" How can i make sure the method always has symbols?! I need to step into every line of code. I am pressing F8 (which is "Step Into" in VS2008, from memory i think it used to be F11 in VS2005). This debugger stuff has always confused me: At the Solution level Property Pages i see a configuration dropdown with 4 values: Active (Debug), Debug, Release, All Configurations. - currently set to "Active (Debug)" At the Project level, i see a configuration dropdown with 2 values: Debug, Release. - currently set to "Debug"

• WebClient vs. HttpWebRequest/HttpWebResponse

  - by Dan

  It seems to me that most of what can be accomplished with HttpWebRequest/Response can also be accomplished with the WebClient class. I read somewhere that WebClient is a high-level wrapper for WebRequest/Response. So far, I can't see anything that can be accomplished with HttpWebRequest/Response that can not be accomplished with WebClient, nor where HttpWebRequest/Response will give you more "fine-grained" control. When should I use WebClient and when HttpWebRequest/Response? (Obviously, HttpWebRequest/Response are HTTP specific.) If HttpWebRequest/Response are lower level then WebClient, what can I accomplish with HttpWebRequest/Response that I cannot accomplish with WebClient?

• MySQL Interview Questions

  - by Campbell

  Hi, I've been asked to screen some candidates for a MySQL DBA / Developer position for a role that requires an enterprise level skill set. I myself am a SQL Server person so I know what I would be looking for from that point of view with regards to scalability / design etc but is there anything specific I should be asking with regards to MySQL? I would ideally like to ask them about enterprise level features of MySQL that they would typically only use when working on a big database. Need to separate out the enterprise developers from the home / small website kind of guys. Thanks.

• Log4r : logger inheritance, yaml configuration, alternatives ?

  - by devlearn

  Hello, I'm pretty new to ruby environments and I was looking for a nice logging framework to use it my ruby and rails applications. In my previous experiences I have successfully used log4j and log4p (the perl port) and was expecting the same level of usability (and maturity) with log4r. However I must say that there are a number of things that are not clear at all in the log4r framework. 1 Logger Inheritance The logger inheritance does not seem to be managed at all ! If I declare a logger named 'myapp' and then try to get a logger name 'myapp::engine', the lookup will end with a NameError. I would expect that the framework returns the root logger according to the naming scheme and to use the 'myapp' logger. Q1 : Of course I can work around this and manage the names by myself with a lookup method, however is there a cleaner way to do this without any extra coding ? 2 YAML configuration Second thing that confuses me is the yaml configuration. On the log4r site there are literally no information about this system, the doc links forward to missing pages, so all the info I can find about is contained in the examples directory of the gem. I was pretty confused with the fact that the yaml configuration must contain the pre_config section, and that I need to define my own levels. If I remove the pre_config secion, or replace all the “custom” levels by the standard ones ( debug, info, warn, fatal ) , the example will throw the following error : log4r/yamlconfigurator.rb:68:in `decode_yaml': Log level must be in 0..7 (ArgumentError) So there seems to be no way of using a simple file where we only declare the loggers and appenders for the framework. Q2 : I realy think that I missed something and that must be a way of providing a simple yaml conf file. Do you have any examples of such an usage ? 3 Variables substitution in XML file Q3 : The Yaml configuration system seems to provide such a feature however I was unable to find a similar feature with XML files. Any ideas ? 4 Alternatives ? I must say that I'm very disappointed by the feature level and the maturity of log4r compared to the log4j and other log4j ports. I run into this framework with a solid background of logging APIs in other languages and find myself working around in all kinds just to make 'basic things' running in a “real world application”. By that I mean a complex application composed of several gems, console/scripting apps, and a rails web front end where the configuration must be mutualized and where we make intensive usage of namespaces and inheritance. I've run several searches in order to find something more suitable or mature, but did not find anything similar. Q4 : Do you guys know any (serious) alternatives to log4r framework that could be used in a enterprise class app ? Thanks reading all of this ! I'd really appreciate any pointers, Kind Regards,

• Display Image over map layer in GeoServer

  - by iririr

  Hi I am newbie when it comes to GeoServer and trying to figure out if there is an easy way to display images on top of map layer. A background: In my application, based on a search criteria, some polygons are drawn on the map. Each polygon has a corresponding image (in TIFF format) that is stored somewhere. I want to load the image on top of the map when the user zooms in to a certain zoom level. I know this can be done using openLayers but since my images are in TIFF format, (openLayers is not able to render TIFF images as far as i know) i have to convert them to .PNG first which would be very slow considering the number of images i have. Hence I was wondering whether it would be possible to create a image layer that would retrieve an image of a certain polygon at a certain zoom level. If so, could anyone point me to an example or give me an idea on whether this is possible. I am using spring 2.5, tomcat 5, java 1.6 and geoserver 2.0 Thanks.

• SQL Server: Database stuck in "Restoring" state

  - by Ian Boyd

  i backed up a data: BACKUP DATABASE MyDatabase TO DISK = 'MyDatabase.bak' WITH INIT --overwrite existing And then tried to restore it: RESTORE DATABASE MyDatabase FROM DISK = 'MyDatabase.bak' WITH REPLACE --force restore over specified database And now the database is stuck in the restoring state. Some people have theorized that it's because there was no log file in the backup, and it needed to be rolled forward using: RESTORE DATABASE MyDatabase WITH RECOVERY Except that, of course, fails: Msg 4333, Level 16, State 1, Line 1 The database cannot be recovered because the log was not restored. Msg 3013, Level 16, State 1, Line 1 RESTORE DATABASE is terminating abnormally. And exactly what you want in a catastrophic situation is a restore that won't work. The backup contains both a data and log file: RESTORE FILELISTONLY FROM DISK = 'MyDatabase.bak' Logical Name PhysicalName ============= =============== MyDatabase C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase.mdf MyDatabase_log C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabase_log.LDF

• Getting Started with UDK

  - by Sean Edwards

  I've been trying for a couple of days now to learn UDK, but I seem to be stuck at making that leap to understanding how everything works together. I understand the syntax, that's all well and good, and I pretty much get how classes and .ini files interact. As for the API, I have the entire reference as pretty decent Doxygen-style HTML output. What I'm looking for is a sort of intermediate tutorial on game creation from scratch (as opposed to modding UT3 itself), more advanced than just learning language syntax, but not yet to the level of going through the API step by step. I'm looking for some guide to the structure of the internals - how GameInfo and PlayerController interact, where Pawn comes in, etc. - a way to visualize the big picture. Does anyone have a particular favorite intermediate-level tutorials (or set of tutorials) that they used when first learning UDK?

• CakePHP: shortcomings with indirectly associated models

  - by Dan

  I'm having some issues with dealing with indirectly associated models in cakephp. My current model setup is as follows: Deliveries hasOne License License belongsTo Delivery License hasAndBelongsToMany Product (and vice-versa) License hasAndBelongsToMany ProductOption (and vice-versa) I'm trying to save information about ALL of these models inside ONE form. The shortcomings I'm running into are the following: The form helper only seems able to see the field type one level deep. saveAll() only seems able to save records one level deep (for multiple model forms). I'm searching everywhere for the solutions to these issues, but since I'm new to CakePHP, I'm not sure what the newest methods or "correct" methods are for dealing with these issues. Any advice is much appreciated. Thank you all! EDIT: I've posted code to my failed attempt here: http://bin.cakephp.org/saved/58501

• What are modern and old compilers written in?

  - by ulum

  As a compiler, other than an interpreter, only needs to translate the input and not run it the performance of itself should be not that problematic as with an interpreter. Therefore, you wouldn't write an interpreter in, let's say Ruby or PHP because it would be far too slow. However, what about compilers? If you would write a compiler in a scripting language maybe even featuring rapid development you could possibly cut the source code and initial development time by halv, at least I think so. To be sure: With scripting language I mean interpreted languages having typical features that make programming faster, easier and more enjoyable for the programmer, usually at least. Examples: PHP, Ruby, Python, maybe JavaScript though that may be an odd choice for a compiler What are compilers normally written in? As I suppose you will respond with something low-level like C, C++ or even Assembler, why? Are there compilers written in scripting languages? What are the (dis)advantages of using low or high level programming languages for compiler writing?

• Hibernate list operation question

  - by Sumit Kishore

  I'm working on a utility to update a list of entities in a database as a group. The database contains a list of entities. The result of the update is a new list. The API accepts this new list. The update may end up modifying some of the entities in the list, creating new ones and deleting some. So at the entity level, I may have to do any of an insert, delete or update operation. But it's always true that the final list in the database will be the same as the list passed down to the API. Is there in Hibernate a way to treat this operation at the list level, that is, tell Hibernate to persist this list of entities, and let it take care of which need to be created, updated or deleted? There is no entity/table representing this list, btw. Just the entities themselves in a table.

• Books about the philosophy of software development

  - by anon

  The first time I read The Mythical Man Month, I found the book utterly boring, a waste of my time, and thought it was written by some management guru that never wrote a line of code. A few years later, I realized Fred Brooks won the Turing award. Some years after that, after a few large development projects, I started understanding what he was talking about. Are there any other books about software development on a meta/philosophical level—not in the sense of design patterns, templates, or even lisp macros—but at a level where ideas are expressed without code?

• *Client* scalability for large numbers of remote web service calls

  - by Yuriy

  Hey Guys, I was wondering if you could share best practices and common mistakes when it comes to making large numbers of time-sensitive web service calls. In my case, I have a SOAP and an XML-RPC based web service to which I'm constantly making calls. I predict that this will soon become an issue as the number of calls per second will grow. On a higher level, I was thinking of batching those calls and submitting those to the web services every 100 ms. Could you share what else works? On a lower level side of the things, I use Apache Xml-Rpc client and standard javax.xml.soap.* packages for my client implementations. Are you aware of any client scalability related tricks/tips/warnings with these packages? Thanks in advance Yuriy

• Just quick: How do you call a mutator from within a constructor in the same class?

  - by Blockhead

  For a homework assignment the instructions state (within Undergrad class): You do NOT need to include a default constructor, but you must write a full parameterized constructor (it takes 4 arguments) -- this constructor calls the parent class parameterized constructor and the mutator for year level. Because Undergrad extends Student, then Student is my parent class, right? I just can't quite figure out how I'm to use my year level mutator (which is just the simplest of methods) to assign my "year" attribute. public void setYear(int inYear) { year = inYear; } public Student(String inName, String inID, int inCredits) { name = inName; id = inID; credits = inCredits; } public Undergrad(String inName, String inID, int inCredits,int inYear) { super(inName, inID, inCredits); year = inYear; } I keep missing assignments because I spend too much time on these small specific points of the homework so just asking for a little help. I swear it's the wording that throws me off on these assignments almost as often as just learning the material itself.

So, can someone please help me with this? Thanks in Advance, Akash P:S I am not in a position to change the db architecture :(

• How can I use a custom ValidationAttribute to ensure two properties match?

  - by Brandon Linton

  We're using xVal and the standard DataAnnotationsValidationRunner described here to collect validation errors from our domain objects and view models in ASP.NET MVC. I'd like to have a way to have that validation runner identify when two properties don't match through the use of custom DataAnnotations. Right now I'm forced into doing it outside of the runner, this way: if (!(model.FieldOne == model.FieldTwo)) errors.Add(new ErrorInfo("FieldTwo", "FieldOne must match FieldTwo", model.FieldTwo)); My question is: can this be done using property-level validation attributes, or am I forced into using class-level attributes (in which case, I'd have to modify the runner...and my follow up question would be how best to retrieve them in that case). Thanks!
