  • How to edit resharper's action list

    - by Gerard
    In Resharper I edited the inspection severity of the 'use var keyword when possible' to ''do not show'. But when I select a certain word in the code file, Resharper still shows a pencil with an Action list in the left border with the action 'use var'. Where can I edit the actions that should be shown? I cannot find this option.

  • solve a classic map-reduce problem with opencl?

    - by liuliu
    I am trying to parallel a classic map-reduce problem (which can parallel well with MPI) with OpenCL, namely, the AMD implementation. But the result bothers me. Let me brief about the problem first. There are two type of data that flow into the system: the feature set (30 parameters for each) and the sample set (9000+ dimensions for each). It is a classic map-reduce problem in the sense that I need to calculate the score of every feature on every sample (Map). And then, sum up the overall score for every feature (Reduce). There are around 10k features and 30k samples. I tried different ways to solve the problem. First, I tried to decompose the problem by features. The problem is that the score calculation consists of random memory access (pick some of the 9000+ dimensions and do plus/subtraction calculations). Since I cannot coalesce memory access, it costs. Then, I tried to decompose the problem by samples. The problem is that to sum up overall score, all threads are competing for few score variables. It keeps overwriting the score which turns out to be incorrect. (I cannot carry out individual score first and sum up later because it requires 10k * 30k * 4 bytes). The first method I tried gives me the same performance on i7 860 CPU with 8 threads. However, I don't think the problem is unsolvable: it is remarkably similar to ray tracing problem (for which you carry out calculation that millions of rays against millions of triangles). Any ideas?

  • AutoMapper How To Map Object A To Object B Differently Depending On Context

    - by IanT8
    Calling all AutoMapper gurus! I'd like to be able to map object A to object B differently depending on context at runtime. In particular, I'd like to ignore certain properties in one mapping case, and have all properties mapped in another case. What I'm experiencing is that Mapper.CreateMap can be called successfully in the different mapping cases however, once CreateMap is called, the map for a particular pair of types is set and is not subsequently changed by succeeding CreateMap calls which might describe the mapping differently. I found a blog post which advocates Mapper.Reset() to get round the problem, however, the static nature of the Mapper class means that it is only a matter of time before a collision and crash occur. Is there a way to do this? What I think I need is to call Mapper.CreateMap once per appdomain, and later, be able to call Mapper.Map with hints about which properties should be included / excluded. Right now, I'm thinking about changing the source code by writing a non-static mapping class that holds the mapping config instance based. Poor performance, but thread safe. What are my options. What can be done? Automapper seems so promising.

  • AndEngine VS Android's Canvas VS OpenGLES - For rendering a 2D indoor vector map

    - by Orchestrator
    This is a big issue for me I'm trying to figure out for a long time already. I'm working on an application that should include a 2D vector indoor map in it. The map will be drawn out from an .svg file that will specify all the data of the lines, curved lines (path) and rectangles that should be drawn. My main requirement from the map are Support touch events to detect where exactly the finger is touching. Great image quality especially when considering the drawings of curved and diagonal lines (anti-aliasing) Optional but very nice to have - Built in ability to zoom, pan and rotate. So far I tried AndEngine and Android's canvas. With AndEngine I had troubles with implementing anti-aliasing for rendering smooth diagonal lines or drawing curved lines, and as far as I understand, this is not an easy thing to implement in AndEngine. Though I have to mention that AndEngine's ability to zoom in and pan with the camera instead of modifying the objects on the screen was really nice to have. I also had some little experience with the built in Android's Canvas, mainly with viewing simple bitmaps, but I'm not sure if it supports all of these things, and especially if it would provide smooth results. Last but no least, there's the option of just plain OpenGLES 1 or 2, that as far as I understand, with enough work should be able to support all the features I require. However it seems like something that would be hard to implement. And I've never programmed in OpenGL or anything like it, but I'm willing very much to learn. To sum it all up, I need a platform that would provide me with the ability to do the 3 things I mentioned before, but also very important - To allow me to implement this feature as fast as possible. Any kind of answer or suggestion would be very much welcomed as I'm very eager to solve this problem! Thanks!

  • How to capture page with google map?

    - by Max
    I have a UIComponent with Google map in the continer. I need to capture this container for making a preview. My integration looks like the following: <mx:UIComponent id="mapContainer" width="410" height="300" /> googleMap = new Map(); mapContainer.addChild(googleMap); But if I do("this" - is my UIComponent) var bmd:BitmapData = new BitmapData(this.width, this.height, true, 0x00ffffff); bmd.draw(this); I see the following: An ActionScript error has occurred: SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: http://localhost/ cannot access http://mt1.google.com/vt/lyrs=m@121&hl=en&src=api&x=1&y=1&z=1&s=Gali. No policy files granted access. at flash.display::BitmapData/draw() I now, that I can to add it host to allowed on the custom client. But I need to have working system on any computer ) I've tried to hide it: templateGoogleMapRenderer.mapContainer.setVisible(false); templateGoogleMapRenderer.mapContainer.includeInLayout = false; But it was unsuccessfully. May be I can override some method in my UIComponent, that flex use during BitmapData/draw() ? Capture with hidden map is success result for me )

  • Finding unreachable sections of a 2D map

    - by dada
    I don't want you to solve this problem for me, i just want to ask for some ideas. This is the input below, and it represents a map. The 'x' represents land, and the dots - water. So with the 'x' you can represent 'islands' on the map. xxx.x...xxxxx xxxx....x...x ........x.x.x ..xxxxx.x...x ..x...x.xxx.x ..x.x.x...x.. ..x...x...xxx ...xxxxxx.... x............ As you can see, there are some islands which are closed, i.e. if some boat is inside its territory, it won't be able to get out, for ex: ..xxxxx. ..x...x. ..x.x.x. ..x...x. ..xxxxx. And there are some open islands which is possible to get out of them, ex: .xxxxx .x...x .x.x.x .xxx.x The problem is this: For a given NxM map like those above, calculate howm any of the islands are open, and how many are closed. I repeat: I don't want you to solve it, just need some sugestions, ideas for solving. thanks

  • Using map/reduce for mapping the properties in a collection

    - by And
    Update: follow-up to MongoDB Get names of all keys in collection. As pointed out by Kristina, one can use Mongodb 's map/reduce to list the keys in a collection: db.things.insert( { type : ['dog', 'cat'] } ); db.things.insert( { egg : ['cat'] } ); db.things.insert( { type : [] }); db.things.insert( { hello : [] } ); mr = db.runCommand({"mapreduce" : "things", "map" : function() { for (var key in this) { emit(key, null); } }, "reduce" : function(key, stuff) { return null; }}) db[mr.result].distinct("_id") //output: [ "_id", "egg", "hello", "type" ] As long as we want to get only the keys located at the first level of depth, this works fine. However, it will fail retrieving those keys that are located at deeper levels. If we add a new record: db.things.insert({foo: {bar: {baaar: true}}}) And we run again the map-reduce +distinct snippet above, we will get: [ "_id", "egg", "foo", "hello", "type" ] But we will not get the bar and the baaar keys, which are nested down in the data structure. The question is: how do I retrieve all keys, no matter their level of depth? Ideally, I would actually like the script to walk down to all level of depth, producing an output such as: ["_id","egg","foo","foo.bar","foo.bar.baaar","hello","type"] Thank you in advance!

  • Java map with values limited by key's type parameter

    - by Ashley Mercer
    Is there a way in Java to have a map where the type parameter of a value is tied to the type parameter of a key? What I want to write is something like the following: public class Foo { // This declaration won't compile - what should it be? private static Map<Class<T>, T> defaultValues; // These two methods are just fine public static <T> void setDefaultValue(Class<T> clazz, T value) { defaultValues.put(clazz, value); } public static <T> T getDefaultValue(Class<T> clazz) { return defaultValues.get(clazz); } } That is, I can store any default value against a Class object, provided the value's type matches that of the Class object. I don't see why this shouldn't be allowed since I can ensure when setting/getting values that the types are correct. EDIT: Thanks to cletus for his answer. I don't actually need the type parameters on the map itself since I can ensure consistency in the methods which get/set values, even if it means using some slightly ugly casts.

  • Serializing and deserializing a map with key as string

    - by Grace K
    Hi! I am intending to serialize and deserialize a hashmap whose key is a string. From Josh Bloch's Effective Java, I understand the following. P.222 "For example, consider the case of a harsh table. The physical representation is a sequence of hash buckets containing key-value entries. Which bucket an entry is placed in is a function of the hash code of the key, which is not, in general guaranteed to be the same from JVM implementation to JVM implementation. In fact, it isn't even guranteed to be the same from run to run on the same JVM implementation. Therefore accepting the default serialized form for a hash table would constitute a serious bug. Serializing and deserializing the hash table could yield an object whose invariants were seriously corrupt." My questions are: 1) In general, would overriding the equals and hashcode of the key class of the map resolve this issue and the map can be correctly restored? 2) If my key is a String and the String class is already overriding the hashCode() method, would I still have problem described above. (I am seeing a bug which makes me think this is probably still a problem even though the key is String with overriding hashCode.) 3)Previously, I get around this issue by serializing an array of entries (key, value) and when deserializing I would reconstruct the map. I am wondering if there is a better approach. 4) If the answers to question 1 and 2 are that I still can't be guaranteed. Could someone explain why? If the hashCodes are the same would they go to the same buckets across JVMs? Thanks, Grace

  • Interactive World Map, highlight countries on mouseover

    - by BrenGG
    I need to create an interactive world map on the front page of a site, the view portal will be about 650x200 pixels. The interactivity would include the following, mouse-over a country would highlight (the countries are will literally be filled with "red" for example) that country and display the countries' name (preferably text in a div), I will also be linking the highlighting event with a that will highlight a country when selected. I am having a difficult time finding a suitable solution, I refuse to use or learn a proprietry technology such as flash so it is not an option. I created a simple mockup using openlayers and a custom map image but the countries' markers load too slowly in IE6. Also svg seems too large, as I tried to use RaphaelJS, but abondoned it when I realised the world map data is 1.2mb which is totally un acceptable for the front page of a site.. I am really at a loss on how I am going to do this, my last resort is to manually create 250+ (however many countries there are) pngs and apply mouseover events to hotspots in the image... but this is probably going to be a dead end too.. desperately seeking a solution, any helpful comments will be appreciated!

  • Refactoring routes - serving different layouts

    - by dmclark
    As a Rails NOOB, I started with a routes.rb of: ActionController::Routing::Routes.draw do |map| map.resources :events map.connect 'affiliates/list', :controller => "affiliates", :action => "list" map.connect 'affiliates/regenerate_thumb/:id', :controller => "affiliates", :action => "regenerate_thumb" map.connect 'affiliates/state/:id.:format', :controller => "affiliates", :action => "find_by_state" map.connect 'affiliates/getfeed', :controller => "affiliates", :action => "feed" map.resources :affiliates, :has_many => :events map.connect ":controller/:action" map.connect '', :controller => "affiliates" map.connect ":controller/:action/:id" map.connect ":controller/:action/:id/:format" end and i'm trying to tighten it up. and I've gotten as far as: ActionController::Routing::Routes.draw do |map| map.resources :events, :only => "index" map.resources :affiliates do |affiliates| affiliates.resources :has_many => :events affiliates.resources :collection => { :list => :get, :regenerate_thumb => "regenerate_thumb" } end # map.connect 'affiliates/regenerate_thumb/:id', :controller => "affiliates", :action => "regenerate_thumb" map.connect 'affiliates/state/:id.:format', :controller => "affiliates", :action => "find_by_state" map.connect 'affiliates/getfeed', :controller => "affiliates", :action => "feed" map.root :affiliates end what is confusing to me is routes vs parameters.. For example, I realized that the only difference between list and index is HOW it is rendered, rather than WHAT is rendered. Having a different action (as I do now) feels wrong but I can't figure out he right way. Thanks

  • How to Map Two Tables To One Class in Fluent NHibernate

    - by Richard Nagle
    I am having a problem with fluent nhiberbate mapping two tables to one class. I have the following database schema: TABLE dbo.LocationName ( LocationId INT PRIMARY KEY, LanguageId INT PRIMARY KEY, Name VARCHAR(200) ) TABLE dbo.Language ( LanguageId INT PRIMARY KEY, Locale CHAR(5) ) And want to build the following class definition: public class LocationName { public virtual int LocationId { get; private set; } public virtual int LanguageId { get; private set; } public virtual string Name { get; set; } public virtual string Locale { get; set; } } Here is my mapping class: public LocalisedNameMap() { WithTable("LocationName"); UseCompositeId() .WithKeyProperty(x => x.LanguageId) .WithKeyProperty(x => x.LocationId); Map(x => x.Name); WithTable("Language", lang => { lang.WithKeyColumn("LanguageId"); lang.Map(x => x.Locale); }); } The problem is with the mapping of the Locale field being from another table, and in particular that the keys between those tables don't match. Whenever I run the application with this mapping I get the following error on startup: Foreign key (FK7FC009CCEEA10EEE:Language [LanguageId])) must have same number of columns as the referenced primary key (LocationName [LanguageId, LocationId]) How do I tell nHibernate to map from LocationName to Language using only the LanguageId field?

  • How to copy_if from map to vector?

    - by VJo
    I'd like to copy values that match a predicate (equal ints) from a map<string,int> to a vector<int>. This is what I tried: #include <map> #include <vector> #include <algorithm> int main() { std::vector< int > v; std::map< std::string, int > m; m[ "1" ] = 1; m[ "2" ] = 2; m[ "3" ] = 3; m[ "4" ] = 4; m[ "5" ] = 5; std::copy_if( m.begin(), m.end(), v.begin(), [] ( const std::pair< std::string,int > &it ) { return ( 0 == ( it.second % 2 ) ); } ); } The error message from g++ 4.6.1 is : error: cannot convert 'std::pair<const std::basic_string<char>, int>' to 'int' in assignment Is there a way to adjust the example to do the above copy?

  • Default update detailViewController, HELP.

    - by DrBeak1
    I've created an app that allows users to add information (from an addViewController), which is then displayed in a UITableView on the rootViewController. When the user taps the tableViewCell the detailViewController then displays, you guessed it, more details regarding the inputted user information. What I'm trying to accomplish is to setup an editViewController that will allow users to edit information they've already submitted. Currently, I'm trying to auto-populate the editViewController with the information that was previously submitted by the user (after which they can press save and update the info). However, I'm getting stuck trying to perform this auto-populating and I'm not sure this is even the best route to accomplish this. Here is the edit method that is called to load the editViewController from the detailViewController. -(IBAction)editDetails:(id)sender { editViewController *evc = [[editViewController alloc] initWithNibName:@"editViewController" bundle:nil]; rootViewController *rvc = [[rootViewController alloc] init]; UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:evc]; [[self navigationController] presentModalViewController:navigationController animated:YES]; ///For Style NSInteger styleCount = [[rvc scoreTypeArray] count]; NSInteger styleRows = [rvc.scoreTypeArray objectAtIndex:indexPath.row]; ///HERE I GET AN ERROR MESSAGE SAYING THAT indexPath IS NOT DEFINED ///For Date NSInteger count = [[rvc dateArray] count]; NSInteger rows = [[rvc indexPath] row]; ///AND HERE I GET A WARNING MESSAGE SAYING rootViewController MAY NOT RESPOND TO INDEX PATH, AND OF COURSE IT DOESN'T WORK [[evc dateField] setText:[NSString stringWithFormat:@"%@", [[evc dateArray] objectAtIndex:(count-1-rows)]]]; [[evc styleField] setText:[NSString stringWithFormat:@"%@", [[rvc scoresArray] objectAtIndex:(styleCount-1-styleRows)]]]; [navigationController release]; [evc release]; [rvc release];} So here I'm trying to load the information from a saved array that is declared in my rootViewController. Any thoughts any body? Please and thank you : )

  • jquery multiple select x rails edit action

    - by VP
    Hi, i'm using the JQUERY multiselectable plugin. Because it's get one select box and transform it in two, where you can move one selected option to another select box. The problem is that i'm facing some problems with the edit action. When i load the form, the selected values (that are saved in my model) are not being populated in the "selected" select box. There is anybody with a good idea about how to "automatically" move the selected values in my database from the "available to be selected" to "selected" options? For now i'm doing something like <%= select "product", :option_ids, options_for_select(Option.all.map { |opt| [opt.description, opt.id]}), {},{:multiple=> true,:class=>'multiselect'} %> Here i can see already the problem. I could just use as options_for_select just all options - the options that are already choosed in my model. The problem is how to update the select box with this information?

  • Updating resources in SharpDX - why can I not map a dynamic texture?

    - by sebf
    I am trying to map a Texture2D resource in DirectX11 via SharpDX. The resource is declared as a ShaderResource, with Default usage and the 'Write' CPU flag specified. My call however fails with a generic exception from SharpDX: _Parent.Context.MapSubresource(_Resource, 0, SharpDX.Direct3D11.MapMode.Write, SharpDX.Direct3D11.MapFlags.None, out stream); I see from this question that it is supported. The MSDN docs and this other question hint that instead of using Context.MapSubresource() I should be using Texture2D.Map(), however, the DirectX11 Texture2D class does not define Map() (though it does for the DX10 equivalent). If I call the above with MapMode.WriteDiscard, the call succeeds but in this case the previous content of the texture is lost, which is no good when I only want to update a section of it. Has the Map() method been removed in DirectX11 or am I looking in the wrong place? Is the MapSubresource() method unsuitable or am I using it wrong?

  • Unity: Is there a way to edit a Skin file?

    - by Roberto
    My project has multiple skins and sometimes we have to deal with skins with many custom styles. Editing them in the editor is difficult, for instance, I cannot delete one style that is not the last one without deleting the ones after it. Would there be a way to edit a file that represents this skin? Could I edit a skin file if I use Text in the Asset Serialization Mode (Unity Pro)? If not, is there something in the Unity Store to help me better edit skins?

  • Stop map from scrolling but let player still move?

    - by ChocoMan
    I have a basic method of scrolling around on a map (moving the map instead of the player), but at when the player gets to a certain proximity to the edge, how do you stop the map from scrolling, but still allow the player to move around until it is away from that proximity? I'm not looking for any code. Just a suggestion so that I can implement it myself. I can see it visually (creating 4 boxed intersecting boundaries for the player to enter), but not sure how to come about stopping and resuming the scrolling of the map.

  • Google Maps API: Premier License or excess map loads?

    - by j0nes
    I am currently looking for a way on how to deal with the Google Maps API usage limits. I am planning a redesign of our page that will probably get around 2 million map loads per month. This will surely break the usage limit of 750000 map loads per month available in the free version. If we pay for excess map loads, this means we would have to pay 5000$ per month. The other option would be to use a Premier license, however there is very few information available on the usage limits for this and the price. I have filled the request form to get a custom offer from Google, but I did not get any response yet. Can anyone of the Premier license holders tell me which option will be cheaper for my usage pattern, paying for Premier license or paying for excess map loads?

  • Is there a size limit when using UICollectionView as tiled map for iOS game?

    - by Alexander Winn
    I'm working on a turn-based strategy game for iOS, (picture Civilization 2 as an example), and I'm considering using a UICollectionView as my game map. Each cell would be a tile, and I could use the "didSelectCell" method to handle player interaction with each tile. Here's my question: I know that UICollectionViewCells are dequeued and reused by the OS, so does that mean that the map could support an effectively infinitely-large map, so long as only a few cells are onscreen at a time? However many cells were onscreen would be held in memory, and obviously the data source would take up some memory, but would my offscreen map be limited to a certain size or could it be enormous so long as the number of cells visible at any one time wasn't too much for the device to handle? Basically, is there any memory weight to offscreen cells, or do only visible cells have any impact?
