Upon examination I find that there is a bunch of unused space in certain tables. I don't do many physical deletes, so I don't think that its just deleted records. DBCC SHRINK doesn't make the file smaller. But, if I dump the table to a new, empty database, the size goes down about 80%. Instead of the 7gb I have in this table in the current database, I end up with about 1.5gb in the fresh database. Its as if sql server is allocating too much memory. Anyone encountered this before? I'd like to be able to shrink the table by removing unused allocated space without having to create a whole new database.

This thing works flawless, unless the service is running on a machine with in the UTC +1 (or +2)timezone. On the response, when in this timezone, my browser's ajax request just hangs until timeout. The DateTime properties are not explicitly initialized before sending the response. What could be causing this? Does initialization matter (my tests say no, but im using DateTime.MinValue as a initial value)?
Although I am using the [MSDN JSONP example][1] for cross domain requests, for same origin I am using just standard WCF bindings and endpoints which return json.

Now, I have since discovered that MySQL was running without a root password (!!) and openly bound to the external IP address (Obviously, I have locked this down now). However, the only root level user in MySQL was `'root'@'localhost'` and `'root'@'127.0.0.1'`, both of which should only have been accessible locally.
So, my question is this:
**Is there a way of spoofing a connection to MySQL so that it will allow connection to the 'root'@'localhost' user from a remote IP address, WITHOUT running any other exploit locally?**

A little background: We've just had our PBX system hacked.

According to [cudaMemcpy documentation][1], this function, can produce 4 differents error codes: "cudaSuccess", "cudaErrorInvalidValue", "cudaErrorInvalidDevicePointer" and "cudaErrorInvalidMemcpyDirection".
However, I get the following error: "cudaErrorLaunchFailure": "An exception occurred on the device while executing a kernel. Common causes include dereferencing an invalid device pointer and accessing out of bounds shared memory. The device cannot be used untilcudaThreadExit() is called. All existing device memory allocations are invalid and must be reconstructed if the program is to continue using CUDA."
Does anybody have any idea about why am I getting this error¿?
What am I doing wrong¿?
Does it make sense, to copy data CPU-->GPU after previous kernel callings ¿? The problem is that, I have to copy that data here at each step because it may change in each "while" step.
Thaks a lot in advance!!

What is the generally accepted usage of a Forms constructor vs it's Form.Load event? With other classes I would do all initialization in the constructor. Yet in in VS when you double click on a Form it jumps you to an event handler for the Form.Load event not the constructor. This leads me to believe that it's preferable to do all the initialization after the Load event instead of the constructor.

Suppose you have a program that is performing some operation on user-supplied information (such as a search string) that changes as the user types it. Suppose that you want to show the user the most relevant information for what they've typed at any given time.
If threads were really abortable, we could simply have one thread running based on the last-changed search string, and cancel any previous threads that were in progress.
Now the generally accepted best practice for doing this today is to use a delay timer as the user types, which waits for .5 to 1 second before initiating the operation. I hope it's obvious enough that this isn't an *ideal* solution, theoretically speaking (any kind of artificial delay imposes an artificial bottleneck that can never be overcome, even if it is only 0.5 seconds).
Furthermore, today's best practice goes on to state that any subsequent operations should wait for the previous one to complete before executing. In a world where we can't abort operations, this makes sense, but again, theoretically speaking this is far from ideal. Imagine the user types a single character and pauses just long enough for the operation to begin. Suppose that this operation takes 10 seconds to execute. The user is now forced to wait an unacceptable amount of time before the results of his/her query are visible.
An (unideal) workaround to this would be to have multiple operations executing concurrently, presuming it is safe to do so, but this would still result in significantly reduced performance.
So I'm just wondering people's thoughts on this, specific to .NET at least, and whether there are any new developments in this area since I last researched it that I should know about (parallel libraries perhaps?). I'd also be curious to know if any other languages/frameworks can handle this sort of fine-grained control of operations better than .NET can.

But the thing is that , before i advance myself to it , i still have a few question that need any expert's help on previous stuff.Actually it's about datatype.
<b>A.)Character Type</b>
1.) I extract the following italize sentences from the book C primer Plus 5th ed.
<i>Somewhat oddly , C treats character constans as type `int` rather than `char`.For example on an ASCII system with a 32-bit `int and an 8-bit `char` , the code
char grade = 'B';
represent 'B' as the numerical value 66 stored in a 32-bit unit , `grade` winds up with 66 stored ub ab 8-bit unit.This characteristic of character constants makes it possible to define a character constant such as `'FATE'` , with four separate 8-bit ASCII codes stored in a 32-bit unit.However , attempting to assign such a character constant to a `char` variable results in only the last 8 bits being used , so the variable gets the value 'E'.</i>
<br />
2.) So the next thing i did after reading this was of course , follow what it mentions , that is i try store the word `FATE` on a variable with char type name `grade` and try to compile and see what it'll be stored using `printf()` , but instead of getting the character `'E'` printed out , what I get is `'F'`.
3.)Does this mean there's some mistake in the book??OR there's someting i misunderstood??
4.)From the above sentences , there's a line says C treats character constants as type `int`.So to try it out , i assign a number bigger than 255 , let's say 356 to the `char` type.
5.)Since 356 is within the range of 32-bit `int`(i'm running windows 7) , therefore i expect it would print out 356 when i use `%d` specifier.
6.)But instead of printing 356 , it gives me 100 , which is the last 8-bits value.
7.)Why this happen??I thought `char` == `int` == 32-bits??(**Although it does mention before char is only a byte).
<br />
<br />
<br />
<b>B.)Int and Floating Type</b>
1.)I understand when a number stores in variable in `short` type is pass to variadic function or any implicit prototype function ,it'll be automatically promoted to `int` type.
2.)This also happen to floating point type , when a floating-point number with `float` type is passed , it'll be converted to `double` type , that is why there's no specifier for the `float` type but instead there's only `%f` for `double and `%Lf` for long double.
3.)But why there's a specifier for `short` type although it is also promoted but not `float` type??Why don't they just give a specifier for `float` type with a modifier like `%hf` or something??Is there anything logical or technical behind this??
<br/>
<br />
Throughout the guidance of stackoverflow communities , I started to learn more , so i wanted to say thanks from the bottom of my heart to you guys.

If this matters, my focus is only on any relation assembly and syntax may have to Linux/BSD and the C language. | linux | bsd | c | assembly | null | 04/01/2012 03:38:54 | not constructive | AT&T vs Intel Syntax and Limitations?

To me, Intel syntax is much easier to read. If I go traipsing through assembly forest concentrating only on Intel syntax, will I miss anything? Is there any reason I would want to switch to AT&T (outside of being able to read others' AT&T assembly)? My first clue is that gdb uses AT&T by default.

E.g. I've got gm10 android tablet pc with android 2.2 on it. It works not so good.
E.g.: I can't even log in skype. I can't even install apps from android market. I can't view flash, i can't, i can't.
Hardware seems to be well supported.
So, my questions:
Is there any chance to get it working fine?
Is it possible to install android 2.3 or android 3.* on it? Will it support the hardware? Where can i get needed drivers? Can I get them from the currently installed android 2.2?
Can I make it forget my e-mail address?
Where is android.git.kernel.org? I can't get access to it.
(i have another tablet pc as well and i want to install new android on it as well, so it is a common question) | android | install | tablet | tablet-pc | null | 09/08/2011 19:59:25 | off topic | Install Android on a device

Can anybody tell me whether it's possible to install android on a tablet pc?
E.g. I've got gm10 android tablet pc with android 2.2 on it. It works not so good.
E.g.: I can't even log in skype. I can't even install apps from android market. I can't view flash, i can't, i can't.
Hardware seems to be well supported.
So, my questions:
Is there any chance to get it working fine?
Is it possible to install android 2.3 or android 3.* on it? Will it support the hardware? Where can i get needed drivers? Can I get them from the currently installed android 2.2?
Can I make it forget my e-mail address?
Where is android.git.kernel.org? I can't get access to it.

We are implementing a payment system on Azure.
When ever account balance is updated in the SQL-azure, we need to make sure that the value is 100% correct.
But we have multiple webroles running, thus they would be able to service two requests concurrently from different customers, that would potentially update current balance for one single product. Thus both instances may read the old amount from database at the same time, then both add the purchase to the old value and the both store the new amount in the database. Who ever saves first will have it's change overwritten. :-(
Thus we need to implement a critical section around all updates to account balance in the database. But how to do that in Azure? Guides suggest to use Azure storage queues for inter process communication. :-)
They ensure that the message does not get deleted from the queue until it has been processed.
Even if a process crash, then we are sure that the message will be processed by the next process. (as Azure guarantee to launch a new process if something hang)
I thought about running a singleton worker role to service requests on the queue. But Azure does not guarantee good uptime when you don't run minimum two instances in parallel. Also when I deploy new versions to Azure, I would have to stop the running instance before I can start a new one. Our application cannot accept that the "critical section worker role" does not process messages on the queue within 2 seconds.
Thus we would need multiple worker roles to guarantee sufficient small down time. In which case we are back to the same problem of implementing critical sections across multiple instances in Azure.
Note: If update transaction has not completed before 2 seconds, then we should role it back and start over.
Any idea how to implement critical section across instances in Azure would be deeply appreciated. | multithreading | azure | queue | null | null | null | open | How to implement critical section in Azure

After further testing it seems that `(~a)` becomes an `int` rather than `unsigned char`. This is why the `1`'s get shifted in.

Over a period of years I have maintained a set of window services that do database functions. I am not revamping the services and I am reviewing the prior strategy for several reasons.
The main one is the complexity and lack of documentation on how to create/install and uninstall a windows service. As the code-base of the service changes you would expect to be able to re-install a new version of the same service. But after some bad experiences I have found myself turning off the service, replacing the files and restarting it. Because the re-install process is very unreliable. And on occasion you will find yourself with a service that is neither fully installed nor fully uninstalled, and it has to be forcefully removed via registry edits.
What I would like to do this time around is install a service wrapper that won't ever change, which in turn invokes a console application. I could potentially even invoke more than one console apps depending on the situation. After some research I found this question [here in stackoverflow](http://stackoverflow.com/questions/1369236/how-to-run-console-application-from-windows-service). Which I don't think resolves the issue of creating windows services.
I also found [srvany.exe](http://support.microsoft.com/kb/137890) which is a really old solution by microsoft. And [RunAsService](http://runasservice.com/) which I would like to get some experiences from before running it on the servers, since I can't find the code-base. But the features of RunAsService do seem close to what I would like to have even if I end up developing one myself for sake of security.

We are considering rolling our own solution, primarily because of cost issues. A central storage server running linux so we have a choice of SAN/NAS options. Something like [this with 5+ PCI slots](http://www.siliconmechanics.com/i36487/2U-storage-server.php)

This gives us the ability to scale to 100+TB for under $35k, which is 1/3 of the cost we're looking at for a solution from Dell, EMC, Sun or HP

public static IUnityContainer ContainerHolder { get; set; }
IUnityContainer IContainerAccessor.Container
{
get { return ContainerHolder; }
}
ContainerHolder, holds the container instance across application and Container property allows access to this property in each session.

public static class UnityLocator

private static IUnityContainer Container
{
get

return ((IContainerAccessor)HttpContext.Current.ApplicationInstance).Container;
}
}
}
Everything works fine!
Now, I'd like to configure my Unit tests to run.
How could I do that?! global.ascx doesn't exist there obviously so I thought I should create a BaseTest class and let all my tests inherit it. then at the constructor of this BaseTest class, I build up my instances. Is it the right way to do it?

The gist is that it is anathema to go "lock yourself in a room" and perform a development task or project for long periods of time. The best practice would be to have a team (at least another person) with you, [commit early and commit often][2], do your work iteratively, etc. etc.
This has become relevant to me because I have an upcoming "internal" project for a [small travel agency business][3], owned and operated by my wife, and we can't afford to hire anyone for it (other than myself of course). The plans/specs that I've drawn up are a little ambitious, but now I'm beginning to doubt if I could pull it off in less than a year if at all.
My question now is, for those of you who have had *no other choice* but to do it all alone (e.g., people who have done successful one-man-projects, or people who are one-man IT departments), what best practices have you found so that you are able to:
- Produce high quality software
- Focus on your tasks and not get distracted or derailed in your work (especially in work-at-home gigs)
- Manage your time
- QA/test your software efficiently
- Maintain best practices in software development like source control, iterative development, etc.
I am particularly interested in people who have done work-at-home setups, as this is where I would likely do my work. I have to mention that we do have a 3 year old around the house, although we have hired a nanny to assist us with her, so that should be taken into account.
I'd love to hear your thoughts.

So why is the precedence not defined to have `++x++` automatically expand to `(++x)++` rather than `++(x++)`?

I've included the intro of the script in a simple page of mine. The script basically writes different things to a string based on logic and echoes the string at the end. Sometimes it echoes a form and when you click on submit, the script runs again and based on the new logic echoes different text that displays fine inside my page where it is included in place of the earlier form. (The 3rd party script included in my page also has some includes of its own.)
My problem is that rather than have it echo some of the things it echoes, notably error os success messages, on occasion I would like to have it redirect to another page on my site.
I've done this successfully with other pages of mine. I include a script in a page that writes some header type code. Based on certain parameters or actions by the user that recall the script, the include may redirect to itself or another page. The only thing I have to make sure is that there are no spaces or text written in the course of the include prior to the redirect.
However working with this third party script, although I think I've removed all the white space, it is not letting me redirect. The error message sites the code written in my page that includes the 3rd party script. Here is the msg:
Warning: Cannot modify header information - headers already sent by (output started at /blah blah/stepone.php:5).
Step one is my simple page that calls the 3rd party script.
Am I right that an include can redirect in response to a user action even if there is some text currently displayed? Should I just be checking the third party scripts for white space or is there some structural thing I may be doing wrong.
The 3rd party scripts are too large to put in here otherwise I would put them in.
Thanks.

g.setColor(Color.red);
g.fillOval(x, y, 5, 5);
}
