  • Image not loading from cache after it's loaded in an iframe

    - by Amir
    I'm loading an image in an iframe and then (once the iframe is loaded) loading the image on the page. But most browsers seem to be loading the image twice. Why isn't the img tag being loading from the cache? Something like this: var loader = $('<iframe />').appendTo('body')[0]; loader.onload = function() { $('body').append('<img src="' + imgsrc + '" />'); }; loader.src = imgsrc; http://jsfiddle.net/amirshim/na3UA/ I'm using fiddler2 to see the network traffic. In case you want to know why I want to do this, check out this question

  • What applications is Python optimal for?

    - by Alan
    I'm already a professional J2EE developer by day, and Rails developer by night. I'm planning on adding Python to my list of skills. I'm already convinced a language is just a tool, so I'm not interested in a religious war. I agree with the Pragmatic Programmers that learning one language/year is a good thing for your professional development So, in your considered opinion, what kinds of applications does Python hit the sweet spot? And why? What advantages does it have, and why do these advantages outweigh the costs in adopting Python? ADD: I also plan on learning a pure functional language like Scheme.

  • DDEX Firebird editing queries duplicates columns in Visual Studio 2008

    - by A Bothe
    Hello everybody! I don't know if some of you also has experienced it but when I edit a query in Visual Studio (it uses DDEX 2.0.5 for accessing the Firebird 2.5 database), it duplicates some of the columns. What's really interesting is the fact that only System.Boolean columns are duplicated: Originally, there was only ,for instance, a 'PRO_DELETED' field... Now I wanted to sort my results by this field - I had to change the select statement in the so-called QueryBuilder by adding "ORDER BY PRO_DELETED" ...After clicking OK it somehow created a new column (!?) called 'PRO_DELETED1' My question is: Why does DDEX add such a new row to the column view and why can't I access the original PRO_DELETED field anymore? Thanks in advance!

  • thread management in nbody code of cuda-sdk

    - by xnov
    When I read the nbody code in Cuda-SDK, I went through some lines in the code and I found that it is a little bit different than their paper in GPUGems3 "Fast N-Body Simulation with CUDA". My questions are: First, why the blockIdx.x is still involved in loading memory from global to share memory as written in the following code? for (int tile = blockIdx.y; tile < numTiles + blockIdx.y; tile++) { sharedPos[threadIdx.x+blockDim.x*threadIdx.y] = multithreadBodies ? positions[WRAP(blockIdx.x + q * tile + threadIdx.y, gridDim.x) * p + threadIdx.x] : //this line positions[WRAP(blockIdx.x + tile, gridDim.x) * p + threadIdx.x]; //this line __syncthreads(); // This is the "tile_calculation" function from the GPUG3 article. acc = gravitation(bodyPos, acc); __syncthreads(); } isn't it supposed to be like this according to paper? I wonder why sharedPos[threadIdx.x+blockDim.x*threadIdx.y] = multithreadBodies ? positions[WRAP(q * tile + threadIdx.y, gridDim.x) * p + threadIdx.x] : positions[WRAP(tile, gridDim.x) * p + threadIdx.x]; Second, in the multiple threads per body why the threadIdx.x is still involved? Isn't it supposed to be a fix value or not involving at all because the sum only due to threadIdx.y if (multithreadBodies) { SX_SUM(threadIdx.x, threadIdx.y).x = acc.x; //this line SX_SUM(threadIdx.x, threadIdx.y).y = acc.y; //this line SX_SUM(threadIdx.x, threadIdx.y).z = acc.z; //this line __syncthreads(); // Save the result in global memory for the integration step if (threadIdx.y == 0) { for (int i = 1; i < blockDim.y; i++) { acc.x += SX_SUM(threadIdx.x,i).x; //this line acc.y += SX_SUM(threadIdx.x,i).y; //this line acc.z += SX_SUM(threadIdx.x,i).z; //this line } } } Can anyone explain this to me? Is it some kind of optimization for faster code?

  • visual studio 2010 add reference version missing

    - by Noel
    In VS2008 when I add a reference to a dll e.g log4Net I get the following in csproj <Reference Include="log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=1b44e1d426115821, processorArchitecture=MSIL"> <SpecificVersion>False</SpecificVersion> <HintPath>..\..\lib\log4net\log4net.dll</HintPath> </Reference> In VS2010 when I add a reference to a dll for the first time e.g log4Net I get the following in csproj (i.e no version number etc) <Reference Include="log4net"> <HintPath>..\..\lib\log4net\log4net.dll</HintPath> </Reference> If I remove reference and add a second time the same details as in VS2008 is there (Version etc) Anyone know why version number etc not present the first time I add a reference and why it is present on secound time reference added?

  • javascript singleton question

    - by Shawn
    I just read a few threads on the discussion of singleton design in javascript. I'm 100% new to the Design Pattern stuff but as I see since a Singleton by definition won't have the need to be instantiated, conceptually if it's not to be instantiated, in my opinion it doesn't have to be treated like conventional objects which are created from a blueprint(classes). So my wonder is why not just think of a singleton just as something statically available that is wrapped in some sort of scope and that should be all. From the threads I saw, most of them make a singleton though traditional javascript new function(){} followed by making a pseudo constructor. Well I just think an object literal is enough enough: var singleton = { dothis: function(){}, dothat: function(){} } right? Or anybody got better insights? [update] : Again my point is why don't people just use a simpler way to make singletons in javascript as I showed in the second snippet, if there's an absolute reason please tell me. I'm usually afraid of this kind of situation that I simplify things to much :D

  • Impersonating a user in wrong domain doesn't throw exception

    - by Rita
    I've used the common impersonation code and it worked just fine, until I inserted random 'dggdgsdg' in domain - and it worked nonetheless... if (LogonUser(Username, Domain, Password, Logon32LogonInteractive, Logon32ProviderDefault, ref existingTokenHandle) && DuplicateToken(existingTokenHandle, (int)SecurityImpersonationLevel.SecurityDelegation, ref duplicateTokenHandle)) { Identity = new WindowsIdentity(duplicateTokenHandle); ImpersonationContext = Identity.Impersonate(); } else { throw new Win32Exception(Marshal.GetLastWin32Error()); } I used some TestUser on my domain, and it worked. I then switched domain, to random nonsense 'werwerhrg', and it impersonated the TestUser on my domain! Why? I would expect an exception to be thrown, why on earth is it working?

  • C++ - Resources in static library question

    - by HardCoder1986
    Hello! This isn't a duplicate of http://stackoverflow.com/questions/531502/vc-resources-in-a-static-library because it didn't help :) I have a static library with TWO .rc files in it's project. When I build my project using the Debug configuration, I retrieve the following error (MSVS2008): fatal error LNK1241: resource file res_yyy.res already specified Note, that this happens only in Debug and Release library builds without any troubles. The command line for Resources page in project configuration looks the same for every build: /fo"...(Path here)/Debug/project_name.res" /fo"...(Path here)/Release/project_name.res" and I can't understand what's the trouble. Any ideas? UPDATE I don't know why this happens, but when I turn "Use Link-Time Code Generation" option on the problem goes away. Could somebody explain why does this happen? I feel like MS-compiler is doing something really strange here. Thanks.

  • Using enums or a set of classes when I know I have a finite set of different options?

    - by devoured elysium
    Let's say I have defined the following class: public abstract class Event { public DateTime Time { get; protected set; } protected Event(DateTime time) { Time = time; } } What would you prefer between this: public class AsleepEvent : Event { public AsleepEvent(DateTime time) : base(time) { } } public class AwakeEvent : Event { public AwakeEvent(DateTime time) : base(time) { } } and this: public enum StateEventType { NowAwake, NowAsleep } public class StateEvent : Event { protected StateEventType stateType; public MealEvent(DateTime time, StateEventType stateType) : base(time) { stateType = stateType; } } and why? I am generally more inclined to the first option, but I can't explain why. Is it totally the same or are any advantages in using one instead of the other? Maybe with the first method its easier to add more "states", altough in this case I am 100% sure I will only want two states: now awake, and now asleep (they signal the moments when one awakes and one falls asleep).

  • How to connect 2 mysql tables with 2 connection string

    - by denonth
    Hi all I need to connect 2 tables from 2 mysql databases that have 2 different connection strings and each is on the different server. I have this query: cmd = new MySqlCommand(String.Format("INSERT INTO {0} (a,b,c,d) SELECT (a,b,c,d) FROM {1}", ConfigSettings.ReadSetting("main_table"), ConfigSettings.ReadSetting("main_table")), con); So both table have the same columns. Thats why I have only one ConfigSettings.ReadSetting("main_table") for both of them as they are same. I have 2 connection strings and each is pointing to their server: con.ConnectionString = ConfigurationManager.ConnectionStrings["con1"].ConnectionString; con2.ConnectionString = ConfigurationManager.ConnectionStrings["con2"].ConnectionString; How to make this cmd to be workking with 2 different connection strings and with the same name for the table. Table name will change that's why it is saved in config.

  • Strange behavior of Switch Case statement in Java

    - by supernova
    I understand that Java switch case are designed this way but why is this behavior in Java int x = 1; switch(x){ case 1: System.out.println(1); case 2: System.out.println(2); case 3: System.out.println(3); default: System.out.println("default"); } output : 1 2 3 default My question is why case 2 and 3 are executed? I know I omitted break statement but x was never 2 or 3 but case 2 and case 3 still executes?

  • Unable to bind with any property of UserControl

    - by Agha Khan
    I looked your answer where I was also using this.DataContext=this. I am unable to convince myself why I have to remove it? But I did In my UserControl control I have 6 int properties (RedCount, GreenCount …) I am using .NET 3.5 and basically I wanted to use StringFormat with Binding. In my xaml file I have 6 Labels with I would like to bind, and I did what exactly you told in last reply. For some strange reasons it didn’t work. I don't know why it does not work. I placed break point in converter where I never hit it. This imples Binding failed.

  • Cached Jquery selector behavior that I do not understand

    - by gaoshan88
    Given the following code why am I getting different values for a and b? I would have thought they would return the same thing: (function() { var a = $('#foo'); var Test = function(){ console.log(a); //outputs 'jQuery()' var b = $('#foo'); console.log(b); //outputs 'jQuery(select#foo)' which is what I want }; })(); This question stems from me trying to stick frequently used selectors into vars. Originally I was doing it in each method (like I did with var b in the above example) but then I found I needed to use the selectors in multiple methods so I moved the assignment out to be available (or so I thought) to all of the methods in that anonymous function. As you can see, it does not work. Why is this?

  • How can I determine which dependency would cause a C++ compilation unit to be rebuilt?

    - by Seb Rose
    I have a legacy C++ application with a deep graph of #includes. Changes to any header file often cause recompiles of seemingly unrelated source files. The application is built using a Visual Studio 2005 solution (sln) file. Can MSBUILD be invoked in a way that it reports which dependency(ies) are causing a source file to be recompiled? Is there any other tool that might be able to help? NOTE: I'm only looking for a tool to tell me why a file would be rebuilt, not some restrospective magic telling me why it was rebuilt.

  • SQL Express as a main DB

    - by JD
    Hi everyone, Does anyone out there use SQL Express 2008 R2 in a production environment? I am looking at hosting a Windows VPS as a server for a client software product I have developed. Clients connect to the server, send their data to a service running on the server, and the service updates the database. I'm trying to keep running costs down, and whilst I have a license for SQL Developer I obviously can't use this in a production environment. Would it be wise/possible to use SQL Express 2008, and if so why/why not? Thanks, JD

    Here's a weird one. I'm developing a responsive site here: http://74.209.178.54:3000/index.html There are three pages built so far: the home page, the "Why" page, and the "Pricing" page. The Home and Why pages are just fine on my iPhone 4. The "Pricing" page is really blurry. And I don't just mean the images are blurry - absolutely everything is blurry: text, borders, backgrounds... Has anyone seen this before? Do you know what's happening?
