  • SQL Server insert slow

    - by andrew007
    Hi, I have two servers where I installed SQL Server 2008 Production: RAID 1 on SCSI disks Test: IDE disk When I try to execute a script with about 35.000 inserts, on the test server I need 30 sec and instead on the production server more than 2 min! Does anybody know why such difference? I mean, the DB is configured in the same way and the production server has also a RAID config, a better processor and memory... THANKS!

  • Why NullPointerException is a runtime exception and RemoteException not?

    - by Tom Brito
    A possible reason because a NullPointerException is a runtime exception is because every method can throw it, so every method would need to have a "throws NullPointerException", and would be ugly. But this happens with RemoteException. And a possible reason because RemoteException is not a runtime exception, is to tell it client to treat the exception. But every method in a remote environment need throws it, so there is no difference of throwing NullPointerException. Speculations? Was I clear?

  • Is there a way to bypass the jQuery error handler?

    - by oravecz
    If my Ajax call returns a successful result, but while processing the result I cause an exception, the error handler fires. This seems counter intuitive to me as I think the error handler should only fire when an error occurs as a result of making the Ajax call or via a server-side error. I am trying to use the Ajax function in a unit test so I would like to tell the difference between the two different failure scenarios.

  • Localization of attribute values in .NET

    - by Alex Angas
    How can I localize/internationalize attribute values in .NET? My specific example is for ASP.NET web parts such as WebDisplayName, WebDescription, etc. where I inherit from the base class that uses these attributes. Also, is there any difference to doing this with attributes declared in my own classes? Thanks!

  • Why would it be necessary to subclass from object in Python?

    - by rmh
    I've been using Python for quite a while now, and I'm still unsure as to why you would subclass from object. What is the difference between this: class MyClass(): pass And this: class MyClass(object): pass As far as I understand, object is the base class for all classes and the subclassing is implied. Do you get anything from explicitly subclassing from it? What is the most "Pythonic" thing to do?

  • GNU Emacs is crashing with -nw

    - by Jack
    When I run emacs with -nw option, the emacs really open, but I can't do more nothing. As if the user input is blocked and no keyboard signal is received and/or interpreted. I've tried run without load .emacs file and some other behaviors: emacs -nw -Q --no-desktop --debug-ini foo.c But makes no difference and strangely the GUI-version(using Gtk) is working fine. My gnu-emacs version is GNU Emacs 23.3.1 Any help to help to fix it is very appreciated.

  • What about buffering FileInputStream?

    - by Pregzt
    I have a piece of code that reads hell of a lot (hundreds of thousand) of relatively small files (couple of KB) from the local file system in a loop. For each file there is a java.io.FileInputStream created to read the content. The process its very slow and take ages. Do you think that wrapping the FIS into java.io.BufferedInputStream would make a significant difference?

  • Objective-C memory management issue

    - by Toby Wilson
    I've created a graphing application that calls a web service. The user can zoom & move around the graph, and the program occasionally makes a decision to call the web service for more data accordingly. This is achieved by the following process: The graph has a render loop which constantly renders the graph, and some decision logic which adds web service call information to a stack. A seperate thread takes the most recent web service call information from the stack, and uses it to make the web service call. The other objects on the stack get binned. The idea of this is to reduce the number of web service calls to only those appropriate, and only one at a time. Right, with the long story out of the way (for which I apologise), here is my memory management problem: The graph has persistant (and suitably locked) NSDate* objects for the currently displayed start & end times of the graph. These are passed into the initialisers for my web service request objects. The web service call objects then retain the dates. After the web service calls have been made (or binned if they were out of date), they release the NSDate*. The graph itself releases and reallocates new NSDates* on the 'touches ended' event. If there is only one web service call object on the stack when removeAllObjects is called, EXC_BAD_ACCESS occurs in the web service call object's deallocation method when it attempts to release the date objects (even though they appear to exist and are in scope in the debugger). If, however, I comment out the release messages from the destructor, no memory leak occurs for one object on the stack being released, but memory leaks occur if there are more than one object on the stack. I have absolutely no idea what is going wrong. It doesn't make a difference what storage symantics I use for the web service call objects dates as they are assigned in the initialiser and then only read (so for correctness' sake are set to readonly). It also doesn't seem to make a difference if I retain or copy the dates in the initialiser (though anything else obviously falls out of scope or is unwantedly released elsewhere and causes a crash). I'm sorry this explanation is long winded, I hope it's sufficiently clear but I'm not gambling on that either I'm afraid. Major big thanks to anyone that can help, even suggest anything I may have missed?

  • How can I change my JLabel to look like a table cell with Substance?

    - by DR
    I have a custom TableCellRenderer which returns a JLabel as the renderer component. Naturally the table cell now looks like a label and no longer like a table cell, which makes a difference especially when using Substance. Is it possible to modify the label so that the LaF renders it like an ordinary table cell? The best I could do was setting the background color of the label, but the borders and transition effets are missing.

  • Static variables in C and C++

    - by Naveen
    Is there any difference between a variable declared as static outside any function between C and C++. I read that static means file scope and the variables will not be accessible outside the file. I also read that in C, global variables are static . So does that mean that global variables in C can not be accessed in another file?

  • Confused about Base class libary and Framework Class Library

    - by n0vic3c0d3r
    Is ADO.NET and ASP.NET a part of Base Class Library? The information given in wikipedia looks ambiguous to me. In the figure, it is shown as a separate block. What is the difference between Base Class Library(BCL) and Framework Class Library(FCL)? Is FCL as a part of .NET Framework? If so why is FCL not shown in the figure as part of .NET framework? Got confused!!

  • C: performance of assignments, binary operations, et cetera...

    - by Shinka
    I've heard many things about performance in C; casting is slow compared to normal assignments, functional call is slow, binary operation are much faster than normal operations, et cetera... I'm sure some of those things are specific to the architecture, and compiler optimization might make a huge difference, but I would like to see a chart to get a general idea what I should do and what I should avoid to write high-performance programs. Is there such a chart (or a website, a book, anything) ?

  • Two method for linking a object using GCC ?

    - by bluewater
    I've known that I should use -l option for liking objects using GCC. that is gcc -o test test.c -L./ -lmy But I found that "gcc -o test2 test.c libmy.so" is working, too. When I use readelf for those two executable I can't find any difference. Then why people use -l option for linking objects? Does it have any advantage?
