Is there a tool to find the difference between two databases.
Both the schema and the actual data are pretty much the same, but not 100%. Do you know a tool that can help to succinctly describe the changes.
I'm wondering what the difference is between the following two modules
# First Example
module Parent
module Child
end
end
and
# Second Example
module Parent::Child
end
Using the 2nd method, it appears as though the Parent module must be previously defined, otherwise I get an 'uninitialized constant' error
Given this, what is the preferred way of defining modules such as this and then adding nested children with regards to syntax and file structure (ie. folders etc). Reference to a Rails way would be greatly appreciated.
Are these two examples for all intents and purposes equivalent?
I would like to know, what is the difference between two statements, these may be simple
String ss="myname";
char[] charArray = ss.toCharArray();
for ( char character : charArray )
{
System.out.println( +character );//Statements are here what does plus refers here:
System.out.println( character ); //Statements are here:
}
I got the output for the code no errors but little doubt on how it works? What happens here?
If you would down vote let me know the reason please ,
Thanks in advance

Considerring two DIVs A and B, which A includes B, and CSS:
A { margin-left: -2000px; }
B { margin-left: 2000px; }
with this CSS, position of B is no difference to its situation with no CSS, i want to know will there be a performance decrease when rendering? Compare to the case of no CSS.
Here's an example of the type of background image I'm talking about...
Clearly, there's a pattern in it. My question is, if this were an iPad app and the background image was twice the size, would there be any significant benefits to taking advantage of this pattern by tiling the image? Or would it really make no difference in terms of performance and just be easier to load the entire image into a UIImageView?
Thanks in advance for all your wisdom!
Hi,

I have 2 integer fields that represent dates in the YYYYMMDD format. What is the best way to subtract 2 of these fields to get the correct # of days between them?
For instance, if I take the difference between 20100511 and 20100428 I would like the result to be 13 and not 83. I know I need to convert the integer fields into date formats but everything I have tried either throws an exception or doesn't work correctly.
What am I missing? Answers in vb.net please
hello.
In general (or from your experience), is there difference in performance between for and while loops?
What if they are doubly/triply nested?
Is vectorization (SSE) affected by loop variant in g++ or Intel compilers?
Thank you
According to Wikipedia NoSQL article, there are a lot of NoSQL implementations.

i can thought that it will open a shell, execute the parameter (shell command) and return the result in a scalar.
But, execute 'system' function in a perl script is faster than a shell command.
It will call this command in C?
If yes, what's the difference between
rmdir foo
and
system('rmdir foo');
Thanks,
I'd like to know the best/easiest way to get a visual diff of a file given 2 revisions in Mercurial.
ie: I'd like to visualize the difference between revision 3 and revision 12, etc.
Can someone explain this to me? In particular the difference between:
http://github.com/whymirror/greg and http://piumarta.com/software/peg/
The former being a re-entrant version of the later.
Hi,

In Visual Studio, I always use Ctrl+Tab and Ctrl+Shift+Tab to navigate between documents. I see that Eclipse has Ctrl+F6 to navigate between editors, but this isn't nearly the same behavior. The difference being, pressing it once and then again will get you moving back and forth between two files, whereas in VS, it will cause you to navigate forward based on the tab order in the editor. Any ideas on how I can replicate VS's behavior?
Hello...,
I have little bit confusion regarding apache tomcat installation.
So, I would like to know that whats the difference between the .zip and the .exe tomcat ?
Thanks in advance...
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?
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!
I cannot find any complete description about LL(*) parser, such as ANTLR, on Internet.
I'm wondering what is the difference between an LL(k) parser and an LL(*) one and why they can't support left-recusrive grammars despite their flexibility.
