• Instantiating and referencing models in MVC

  - by fig-gnuton

  In MVC, should each model be a globally accessible singleton accessible to any view/controller? Or should the models be singletons that are dependency injected into any component that requires them? Or should a new model instance be created for each component that needs one, in which case events would be used to propagate changes across model instances of the same class?

• PHP: SUBMIT Type vs IMAGE Type

  - by sebb

  I have noticed that when using a SUBMIT type its name attribute gets passed via POST , while an IMAGE type button do not have this data sent, can any one clear this up for me?

• Windsor OnCreated for all components

  - by jeffn825

  Hi, How would I go about globally intercepting the creation/resolution of all instances by my container? I know I can do this individually with OnCreated on a per-component basis, but I want to do this globally for all objects resolved by the container. Thanks.

• How to free static member variable in C++?

  - by user299831

  Can anybody explain how to free memory of a static member Variable? In my understanding it can only be freed if all the instances of the class are destroyed. I am a little bit helpless at this point... Some Code to explain it: class ball { private: static SDL_Surface *ball_image; }; //FIXME: how to free static Variable? SDL_Surface* ball::ball_image = SDL_LoadBMP("ball.bmp");

• Why should Java ThreadLocal variables be static

  - by kellyfj

  I was reading that JavaDoc for Threadlocal here http://java.sun.com/j2se/1.5.0/docs/api/java/lang/ThreadLocal.html and it says "ThreadLocal instances are typically private static fields in classes that wish to associate state with a thread (e.g., a user ID or Transaction ID). " But my question is why did they choose to make it static (typically) - it makes it a bit confusing to have "per thread" state but its static?

• C#. Where struct methods code kept in memory?

  - by maxima120

  It is somewhat known where .NET keeps value types in memory (mostly in stack but could be in heap in certain circumstances etc)... My question is - where is the code of the struct? If I have say 16 byte of data fields in the struct and a massive computation method in it - I am presuming that 16 byte will be copied in stack and the method code is stored somewhere else and is shared for all instances of the struct. Are these presumptions correct?

• Amazon Elastic MapReduce: the number of launched map task

  - by S.N

  Hi, In the "syslog" for a MapReduce job flow step, I see the following: Job Counters Launched reduce tasks=4 Launched map tasks=39 Does the number of launched map tasks include failed tasks? I am using NLineInputFormat class as input format to manage the number of map tasks. However, I get slightly different numbers for exact same input occasionally, or depending on the number of instances (10, 15, and 20). Can anyone tell me why I am seeing different number of tasks launched?

• Support for multiple repositories using Buildbot

  - by Kiffin

  Currently Buildbot does not support multiple repositories. If one desires to have this then separate instances of Buildbot need to be run. Still I'm curious if anyone has come up with a creative workaround to get this feature working anyway.

• Are methods also serialized along with the data members in C#?

  - by Shaza

  Hey all, The title is obvious, I need to know if methods are serialized along with object instances in C#, I know that they don't in Java but I'm a little new to C#. If they don't, do I have to put the original class with the byte stream(serialized object) in one package when sending it to another PC? Can the original class be like a DLL file?

• How to connect to local database via website?

  - by Carlo

  Hi I have a website used by clients for reporting purposes and would like to give clients the option of my website reading their local database directly (instead of them providing data in a file format). In most instances their database would be SQL Express setup on their localhost. How can I connect to a clients local SQL server via my website, using asp.net / javascript etc? If the client provides their connection string properties, localhost would just refer to my server's localhost... Thanks

• Google App Engine - Is there a way to get some sort of current time that would be consistent across

  - by Spines

  If I call new Date() it will get the current time for the machine my app is running on. I'm assuming that the machines on the Google App Engine do not all have their time synchronized. Is there a way to get a time that would be consistent across instances of my app that may be running on different machines?

  Each input field in the CKEditor dialogs are renamed with a unique number, but the number changes depending on what options are visible.

• How do I debug a Unity Container "Resolve"?

  - by willem

  I'm using the MS Unity container to do dependency injection, but a "Resolve" is returning unexpected results. Is there an way I can debug this resolution? It would be great if I could view what Types/Instances are registered in the container, but I can't see where this is stored when using QuickWatch. It would also be useful if I could get the container to output some debug Traces. Any suggestions?
