  • Grails Detect if a Plugin is Installed

    - by Scott Warren
    Is there a way in Grails to Detect that a plugin is installed. For example I need to know if the "Acegi" plugin is installed. If it is then I can run different Code. If the plugin is not installed (which is a viable option) then I can run different code. Thanks in Advance.

  • Facebook-WordPress comment/feedback integration

    - by warren
    Currently I have my Facebook profile automatically republish blog posts from a WordPress instance. What I would like to be able to do, however, is to also have comments posted to either the blog of Facebook show up on the other in the appropriate location. Is there a way to do this with the Facebook API?

  • Macro to improve callback registration readability

    - by Warren Seine
    I'm trying to write a macro to make a specific usage of callbacks in C++ easier. All my callbacks are member functions and will take this as first argument and a second one whose type inherits from a common base class. The usual way to go is: register_callback(boost::bind(&my_class::member_function, this, _1)); I'd love to write: register_callback(HANDLER(member_function)); Note that it will always be used within the same class. Even if typeof is considered as a bad practice, it sounds like a pretty solution to the lack of __class__ macro to get the current class name. The following code works: typedef typeof(*this) CLASS; boost::bind(& CLASS :: member_function, this, _1)(my_argument); but I can't use this code in a macro which will be given as argument to register_callback. I've tried: #define HANDLER(FUN) \ boost::bind(& typeof(*this) :: member_function, this, _1); which doesn't work for reasons I don't understand. Quoting GCC documentation: A typeof-construct can be used anywhere a typedef name could be used. My compiler is GCC 4.4, and even if I'd prefer something standard, GCC-specific solutions are accepted.

  • Selecting items from events, as evenly spaced as possible

    - by Matt Warren
    If I have an event that happens 15 times a second (numbered 1 - 15), but I only want to process it 3 times I can choose [1], [6] and [11],. It's important that the events I process are as evenly spaced as possible and take into account wrap-around, i.e. the events are continuous 13, 14, 15, 1, 2, 3 etc. If I want 4 items the best I can do is [1], [5], [9] & [13]. Is there a general algorithm that will calculate which events I need to process given the total number of events (total) and the number to process (processAmount).

  • Can I move the order of XCode, Cocoa, and User Templates around in XCode 3.1?

    - by Warren P
    I followed the other questions on StackOverflow and made custom User Templates. Instead of replacing the factory default Cocoa class template, I have to pick a new user template. The order that is shown in XCode's New File dialog box is: iPhone templates first (great if you mostly do iphone development) Second the User templates Third the default Mac OS templates. I want my user stuff first, Mac OS templates second, and I want to bury iPhone templates in third and last place. The sort is obviously not alphabetical. And you can't drag/drop reorder. (At least not in xcode 3.1.3)? From stackoverflow

  • How to 'insert if not exists' in MySQL?

    - by warren
    I started by googling, and found this article which talks about mutex tables. I have a table with ~14 million records. If I want to add more data in the same format, is there a way to ensure the record I want to insert does not already exist without using a pair of queries (ie, one query to check and one to insert is the result set is empty)? Does a unique constraint on a field guarantee the insert will fail if it's already there? It seems that with merely a constraint, when I issue the insert via php, the script croaks.

  • Delphi component you can't live without?

    - by Warren P
    Most delphi developers have a list of delphi components they wouldn't live without. Not including anything that ships with Delphi (standard VCL or included third-party software like Rave or Indy), what are the components you can't live without, be they commercial or open-source? I will refrain from adding my own answers unless this becomes a community wiki. One component name, or product name, per answer please. Please vote up on components and do not post duplicates.

  • Exemplars of large document-centric applications with COM/XPCOM/.NET interfaces.

    - by Warren P
    I am looking for exemplars (design examples) showing the use of interfaces (aka 'protocols' for you smalltalkers) to design a document management architecture in a large Word Processor, Spreadsheet, vector graphic or publishing package, or office-productivity (non-database) application with support for as many of the following as possible: any open source project, will be ideal, and language of implementation is unimportant since I am looking for design examples, however an object oriented language with support for "interfaces" is a must. I know at least a dozen languages, and I'm willing to study any application's source. use of "interface" could loosely be applied to either XPCOM or COM interfaces, or .NET interfaces, or even the use of pure-virtual (virtual+abstract) base-classes for OOP languages that lack the ability to declare an interface distinct from a class. I am mostly looking for a robust, thorough and flexible implementation for a document, IDocument, various document views (IDocumentView), and whatever operations make sense in that case. I am particular interested in cases where the product in question is a real-world product. For example, if anybody familiar with OpenOffice can tell me if the code contains a good sample design. I am looking for design documentation that outlines the design of the interfaces for such an application. So for example, if the openoffice spreadsheet has such an interface design, then that might be the best case, because it is a widely used real-world design, with millions of users, rather than a textbook example, which is minimal, and contrived. I know that the Mozilla platform uses XPCOM, and its design is heavily "interface" oriented, but I am looking more for a "word processor" or "spreadsheet" type of document design, rather than a web-browser. I am particularly interested in the interfaces used to access to data and meta-data such as markup (attributes like bold, and italics, and font size), and the ability to search and look up named entities within a document.

  • Force an object to be allocated on the heap

    - by Warren Seine
    A C++ class I'm writing uses shared_from_this() to return a valid boost::shared_ptr<>. Besides, I don't want to manage memory for this kind of object. At the moment, I'm not restricting the way the user allocates the object, which causes an error if shared_from_this() is called on a stack-allocated object. I'd like to force the object to be allocated with new and managed by a smart pointer, no matter how the user declares it. I thought it could be done through a proxy or an overloaded new operator, but I can't find a proper way of doing that. Is there a common design pattern for such usage? If it's not possible, how can I test it at compile time?

  • Typedef equivalence in function arguments

    - by Warren Seine
    Hi guys, The question is kind of hard to ask without an example so here it is: #include <vector> struct O { }; struct C { template <typename T> void function1(void (C::*callback)(const O*)); template <typename T> void function2(void (C::*callback)(const typename T::value_type)); void print(const O*); }; int main() { C c; c.function1< std::vector<O*> >(&C::print); // Success. c.function2< std::vector<O*> >(&C::print); // Fail. } The error that I am given is: error: no matching function for call to ‘C::function2(void (C::*)(const O*))’. Basically, the only difference between calls is that in function2, I'm more generic since I use the typedef std::vector<O*>::value_type which should resolve to O*, hence similar to function1. I'm using G++ 4.2.1 (I know it's old), but Comeau confirms I'm wrong. Why does the compilation fail?

  • does a git repository have its own local value for core.autocrlf that overrides the global one?

    - by Warren P
    As per this question, I understand that core.autocrlf=true in git will cause CRLF to LF translations. However when I type : git config core.autocrlf I see: false However, when I stage modified files that are already in the repo, I still get these warnings: Warning: CRLF will be replaced by LF in File1.X. The file will have its original line endings in your working directory. My guess is that the repo copy of the file is already set to "autocrlf=true". Questions: A. How do I query whether a file or git repo is already forcing AutoCrlf? B. How do I turn it autocrlf off?

  • An Array returned by a model association is not an Array?

    - by Warren
    We have a model association that looks something like this: class Example < ActiveRecord::Base has_many :others, :order => 'others.rank' end The rank column is an integer type. The details of these particular models are not really important though as we have found the same problem with other has_many associations between other models. We have also added to the Enumerable module: module Enumerable def method_missing(name) super unless name.to_s[0..7] == 'collect_' method = name.to_s[8..-1] collect{|element| element.send(method)} end end This adds a collect_id method that we can use to get an array of record ids from an array of ActiveRecord objects. So if we use a normal ActiveRecord find :all, we get a nice array which we can then use collect_id on but if we use Example.others.collect_id, we get NoMethodError: undefined method `collect_id' for #<Class:0x2aaaac0060a0> Example.others.class returns "Array" so is it lying or confused? Our solution thus far has been to use it this way: Example.others.to_a.collect_id This works but this seems a bit strange. Why would you have to do that? We are on Ruby 1.8.7 and Rails 2.3.4

  • How to access property in sub method after it runs?

    - by Warren
    I'm having a hard time working this one out but I think it should be pretty simple. Basically, I have this method which talks to a webservice and I need to return some data from the sub method, the "authCode". What am I doing wrong? How can I get the authCode out of the manager, or can I create a block or something to to ensure that the manager block runs first? Am I even using the right words - blocks, sub methods??? Please help :) - (NSString *)getAuthCodeEXAMPLE { __block NSString *returnString = @"nothing yet!"; NSURL *baseURL = [NSURL URLWithString:BaseURLString]; NSDictionary *parametersGetAuthCode = @{@"req": @"getauth"}; AFHTTPSessionManager *manager = [[AFHTTPSessionManager alloc] initWithBaseURL:baseURL]; manager.responseSerializer = [AFJSONResponseSerializer serializer]; [manager POST:APIscript parameters:parametersGetAuthCode success:^(NSURLSessionDataTask *task, id responseObject) { if ([task.response isKindOfClass:[NSHTTPURLResponse class]]) { NSHTTPURLResponse *r = (NSHTTPURLResponse *)task.response; if ([r statusCode] == 200) { self.returnedData = responseObject; NSString *authCode = [self.returnedData authcode]; NSLog(@"Authcode: %@", authCode); returnString = authCode; } } } failure:^(NSURLSessionDataTask *task, NSError *error) { UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error" message:[error localizedDescription] delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil]; [alertView show]; }]; //this currently returns "nothing yet!" return returnString; }

  • Best way to randomly select rows *per* column in SQL Server

    - by LesterDove
    A search of SO yields many results describing how to select random rows of data from a database table. My requirement is a bit different, though, in that I'd like to select individual columns from across random rows in the most efficient/random/interesting way possible. To better illustrate: I have a large Customers table, and from that I'd like to generate a bunch of fictitious demo Customer records that aren't real people. I'm thinking of just querying randomly from the Customers table, and then randomly pairing FirstNames with LastNames, Address, City, State, etc. So if this is my real Customer data (simplified): FirstName LastName State ========================== Sally Simpson SD Will Warren WI Mike Malone MN Kelly Kline KS Then I'd generate several records that look like this: FirstName LastName State ========================== Sally Warren MN Kelly Malone SD Etc. My initial approach works, but it lacks the elegance that I'm hoping the final answer will provide. (I'm particularly unhappy with the repetitiveness of the subqueries, and the fact that this solution requires a known/fixed number of fields and therefore isn't reusable.) SELECT FirstName = (SELECT TOP 1 FirstName FROM Customer ORDER BY newid()), LastName= (SELECT TOP 1 LastNameFROM Customer ORDER BY newid()), State = (SELECT TOP 1 State FROM Customer ORDER BY newid()) Thanks!

  • Google App Engine - Spring Security Issue (java.security.AccessControlException)

    - by Taylor L
    I'm currently getting the AccessControlException below when I deploy to app engine (I don't see it when I run in my local environment). I'm using GAE 1.3.1, Spring 3.0.1, and Spring Security 3.0.2. Any ideas how to get around this issue?

  • Entity Framework with MySQL - Timeout Expired while Generating Model

    - by Nathan Taylor
    I've constructed a database in MySQL and I am attempting to map it out with Entity Framework, but I start running into "GenerateSSDLException"s whenever I try to add more than about 20 tables to the EF context. An exception of type 'Microsoft.Data.Entity.Design.VisualStudio.ModelWizard.Engine.ModelBuilderEngine+GenerateSSDLException' occurred while attempting to update from the database. The exception message is: 'An error occurred while executing the command definition. See the inner exception for details.' Fatal error encountered during command execution. Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. There's nothing special about the affected tables, and it's never the same table(s), it's just that after a certain (unspecific) number of tables have been added, the context can no longer be updated without the "Timeout expired" error. Sometimes it's only one table left over, and sometimes it's three; results are pretty unpredictable. Furthermore, the variance in the number of tables which can be added before the error indicates to me that perhaps the problem lies in the size of the query being generated to update the context which includes both the existing table definitions, and also the new tables that are being added to it. Essentially, the SQL query is getting too large and it's failing to execute for some reason. If I generate the model with EdmGen2 it works without any errors, but the generated EDMX file cannot be updated within Visual Studio without producing the aforementioned exception. In all likelihood the source of this problem lies in the tool within Visual Studio given that EdmGen2 works fine, but I'm hoping that perhaps others could offer some advice on how to approach this very unique issue, because it seems like I'm not the only person experiencing it. One suggestion a colleague offered was maintaining two separate EBMX files with some table crossover, but that seems like a pretty ugly fix in my opinion. I suppose this is what I get for trying to use "new technology". :(

  • ELMAH - Filtering 404 Errors

    - by Nathan Taylor
    I am attempting to configure ELMAH to filter 404 errors and I am running into difficulties with the XML-provided filter rules in my Web.config file. I followed the tutorial here and here and added an <is-type binding="BaseException" type="System.IO.FileNotFoundException" /> declaration under my <test><or>... declaration, but that completely failed. When I tested it locally I stuck a breakpoint in protected void ErrorLog_Filtering() {} of the Global.asax found that the System.Web.HttpException that gets fired by ASP.NET for a 404 doesn't have a base type of System.IO.FileNotFound, but rather it is simply a System.Web.HttpException. Next I decided to try a <regex binding="BaseException.Message" pattern="The file '/[^']+' does not exist" /> in the hopes that any exception matching the pattern "The file '/foo.ext' does not exist" would get filtered, but that too having no effect. As a last resort I tried <is-type binding="BaseException" type="System.Exception" />, and even that is entirely disregarded. I'm inclined to think there's a configuration error with ELMAH, but I fail to see any. Am I missing something blatantly obvious? Here's the relevant stuff from my web.config: <configuration> <configSections> <sectionGroup name="elmah"> <section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah"/> <section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah"/> <section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah"/> <section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah" /> </sectionGroup> </configSections> <elmah> <errorFilter> <test> <or> <equal binding="HttpStatusCode" value="404" type="Int32" /> <regex binding="BaseException.Message" pattern="The file '/[^']+' does not exist" /> </or> </test> </errorFilter> <errorLog type="Elmah.XmlFileErrorLog, Elmah" logPath="~/App_Data/logs/elmah" /> </elmah> <system.web> <httpModules> <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah"/> <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah"/> </httpModules> </system.web> <system.webServer> <modules> <add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah"/> <add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" /> </modules> </system.webServer> </configuration>
