  • What's the purpose of having a separate "operator new[]" ?

    - by sharptooth
    Looks like operator new and operator new[] have exactly the same signature: void* operator new( size_t size ); void* operator new[]( size_t size ); and do exactly the same: either return a pointer to a big enough block of raw (not initialized in any way) memory or throw an exception. Also operator new is called internally when I create an object with new and operator new[] - when I create an array of objects with new[]. Still the above two special functions are called by C++ internally in exactly the same manner and I don't se how the two calls can have different meanings. What's the purpose of having two different functions with exactly the same signatures and exactly the same behavior?

  • Chaining multiple MapReduce jobs in Hadoop.

    - by Niels Basjes
    In many real-life situations where you apply MapReduce, the final algorithms end up being several MapReduce steps. I.e. Map1 , Reduce1 , Map2 , Reduce2 , etc. So you have the output from the last reduce that is needed as the input for the next map. The intermediate data is something you (in general) do not want to keep once the pipeline has been successfully completed. Also because this intermediate data is in general some data structure (like a 'map' or a 'set') you don't want to put too much effort in writing and reading these key-value pairs. What is the recommended way of doing that in Hadoop? Is there a (simple) example that shows how to handle this intermediate data in the correct way, including the cleanup afterward? Thanks.

  • MySQL: Copy a field to another table

    - by harpax
    I have a table posts that could look like this: id | title | body | created | .. ------------------------------------------- I would like to use the boolean search feature that is offered by a MyISAM Table, but the posts table is InnoDB. So I created another table 'post_contents' that looks like this: post_id | body -------------------- That table is already filled with some contents and I can use the boolean search. However, I need to move the title field in the post_contents table as well and then copy the existing title-data to the new field. I know about the INSERT .. SELECT syntax, but I don't seem to be able to create the correct query.

  • Hot to: user AutoCompleteExtender in a UserControl (ascx) and place the ServiceMethod on its code-be

    - by Shimmy
    Hi! I created a AutoCompleteExtender on a TextBox that resides on a UserControl (Control.ascx file). I don't want to create a separate class for the web method, i rather placing it in the code file (Control.ascx.cs) itself. Is there a way? I have successfully tried once ago placing the method on the same page but it was a page, and if ServicePath property is not set it's automatically refered to the page so it worked, now since it's a user control it doesn't even when I explicitly specify the path.

  • If you have an application localized in pt-br and pt-pt, what language you should choose if the syst

    - by Sorin Sbarnea
    If you have an application localized in pt-br and pt-pt, what language you should choose if the system is reporting only pt code (generic Portuguese)? This question is independent of the nature of the application, desktop, mobile or browser based. Let's assume you are not able to get region information from another source and you have to choose one language as the default one. The question does apply as well for more case including: * pt-pt and pt-br * en-us and en-gb * fr-fr and fr-CA * zh-cn, zh-tw, .... - in fact in this case I know that zh can be used as predominant language for Simplified Chinese where full code is zh-hans. For zh-tw, zh-hant-tw, zh-hk, zh-mo the proper code (canonical) should be zh-hant. In fact the question can be extended to: How to I determine the predominant languages for a specified meta-language? I need a solution that will include at least Portuguese, English and French.

  • CPU Benchmark - Set Load, usage spikes

    - by iulianchira
    I need a CPU benchmark to test the performance impact of various power management policies. I must be able to set the load (e.g. to get a relatively steady load of 20%-30%-60%) and to simulate usage spikes (set frequency of spikes). I would also like it to be scriptable so as to be able to change benchmark settings in an indirect manner.

  • Configure Mouse Buttons for "Administrator"/Elevated privileges

    - by Zhaph - Ben Duguid
    I am, for better or worse, an administrator on my Windows 7 machine. However, even then, I still need to run certain programs "as Administrator" - for example, Visual Studio 2008 when working with local IIS sites. I also like to have the extra buttons on my IntelliMouse Optical doing non-standard things, like representing Ctrl and Shift. However, when in VS running as administrator, these settings aren't picked up, just like my mapped drives aren't picked up - I would understand this if I was logging in as a different user, supplying credentials, etc, but I'm not, I'm just pressing "Yes" at the UAC prompt. Normally, I'd just right click the item in the start menu and select "Run as administrator", but that's not an option on the context menu for either the Microsoft IntelliPoint Mouse application that appears under "Programs", nor the "Mouse" control panel item. Running the control panel as administrator also doesn't seem to help. So has any one got any suggestions on how I can configure my mouse buttons for the elevated version of me that Visual Studio is running as?

  • System.DirectoryServices.AccountManagement not working on the server

    - by mlsteeves
    I am using System.DirectoryServices.AccountManagement to find the logged-in user's AD entry. It is working great in the VS2008 WebDev server on developers machines. But when we installed the code on the development server (windows server 2008), we get an access error. Both the developer's machine and the development server are members of the same domain. We have Impersonation turned on, so we are connecting to AD with the same user credentials. What are we missing here? Why is it working on the developer's machine, but not the development server? The actual exception that we were receiving was "An operations error occurred".
