I have been coming across these two words more often but i didn't see much difference in these? I mean want to know are they used interchangeably or there are some differences in those two?
Thanks.
Here's a phrase that I heard a lot throughout high school and university computer science classes:
"That's not an issue for modern JVMs."
Usually this would come up in discussions about overall performance or optimization strategies. It was always treated as a kind of magical final answer, though, as if it makes issues no longer worth thinking about. And that just leads me to wonder: what are the differences between the prototypical "modern JVM" and older JVMs, really?
What is the meaning of "parallel software" and what are the differences between "parallel software" and "regular software"?
What are its advantages and disadvantages?
Does writing "parallel software" require a specific hardware or programming language ?
I consider myself quite fluent in PHP and am rather familiar with nearly all of the important aspects and uses, as well as its pratfalls. This in mind, I think the major problem in taking on Perl is going to be with the syntax. Aside from this (a minor hindrance, really, as I'm rather sold on the fact that Perl's is far more readable), what are some key differences you think I should make myself aware of prior to taking on the language?
Hello all
I am looking for compare utility similar for "win merge" or "beyond compare" .
That in addition for gui comparison will have api that i will be able to run on my files via my code and see if the files are the same or not and also use it in gui mode to show graphically the differences .
Any recommendations ?
thanks
Qt is a nice framework which allows people to develop something once and it will works for the 3 main OSes.
But from times to times, there is some differences in the layout: placing some widgets does not have the same behavior as in windows or linux.
Did you observe weird behavior ? on which Widgets ? how did you corrected this ?
Thanks for sharing
I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority.
The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one.
Has anyone done a performance comparison between any of these?
Am surprised there's 3 different forms: RawConfigParser, SafeConfigParser and ConfigParser. I read the differences but why isn't everyone using SafeConfigParser, since it seems, well, safe? I can understand that in the case for Python 2 that the other two were kept for backward compatibility.
When the c++ compiler generates very similar assembler code for a reference and pointer, why is using references preferred (and considered safer) compared to pointers?
I did see
Difference between pointer variable and reference variable in C++ which discusses the differences between them.
EDIT-1:
I was looking at the assembler code generated by g++ for this small program:
int main(int argc, char* argv[])
{
int a;
int &ra = a;
int *pa = &a;
}
I have some nested datastructures, each something like:
[ ('foo', [ {'a':1, 'b':2},
{'a':3.3, 'b':7} ]),
('bar', [ {'a':4, 'd':'efg', 'e':False} ]) ]
I need to compare these structures, to see if there are any differences. Short of writing a function to explicitly walk the structure, is there an existing library or method of doing this kind of recursive comparison?
Are there any ways to determine what the differences in databases are that affect a SSIS package load performance ?
I've got a package which loads and does various bits of processing on ~100k records on my laptop database in about 5 minutes
Try the same package and same data on the test server, which is a reasonable box in both CPU and memory, and it's still running ... about 1 hour so far :-(
Checked the package with a small set of data, and it ran through Ok
Hi Guys,
a bit of a vague question but I am looking for pointers as to how can I generate String diff vectors in C++. The scenario is such that given a paragraph I want to store the various differences(Edit, cut copy paste etc.) it goes through in a draft mode to review Audit history.
Any hints in this regard will be really appreciated.
Is there any differences between ": file" and " file"?

What differences are there between the top level architectures of Cobol and Java?
What are the styles and cultures that programmers adopt in these two languages?
How can one best port from Cobol to Java?
I'm looking for an explanation of the different functionality in versions of a application called VMAC (Verix blah blah blah), also called "comm server", which is used on Verifone payment terminals. I've got terminals with versions 1.7 and 3.3 of VMAC, and I'm unaware of the differences.
If someone is a Verifone expert, it would be helpful to know how much of the communication with the processing host vs the merchant services provider's application.
Can anyone answer me what are the differences of
Session.Query
Session.Linq and
Session.QueryOver
What I'm really interested in:
What would be supported in the future versions.
What should I start to use in a clean project.
Please tell me your thoughts about these three...
Thanks,
Zoltán
I'm curious - does the listing of assemblies in the Add Reference dialog vary depending on the version of the .Net framework used for the selected project. If they do differ, I'd love to know where the differences lie. Thanks!
What are the similarities and the differences between Haskell's TypeClasses and Go's Interfaces? What are the relative merits / demerits of the two approaches?
MSDN says that you should use structs when you need lightweight objects. Are there any other scenarios when a struct is preferable over a class?
Edit:
Some people have forgotten that:
1. structs can have methods!
2. structs have no inheritance capabilites.
Another Edit:
I understand the technical differences, I just don't have a good feel for WHEN to use a struct.
Apart from performance concerns, should web-based applications be built differently according to the number of (concurrent) users? If so, what are the main differences for (say) 4, 40, 400 and 4000 users?
I'm particularly interested in how logging, error handling, design patterns etc. would be be used according to the number of concurrent users.
I am an experienced C/C++/C# programmer who has just gotten into VB.NET. I generally use CType (and CInt, CBool, CStr) for casts because it is less characters and was the first way of casting which I was exposed to, but I am aware of DirectCast and TryCast as well.
Simply, are there any differences (effect of cast, performance, etc.) between DirectCast and CType? I understand the idea of TryCast.
I'm new to SSRS. We'll have two slightly different chunks of XML in a single row of an SQL Server database table. In an SSRS report we'll want to show only the differences between the XML chunks. I don't know how to do this, but I suspect the XML Type in SQLServer 2005 might be useful, or XSLT transformations in SSRS. Could anyone point me in the right direction?
