The man page of epoll_ctl() says about EPOLLPRI:
There is urgent data available for
read(2) operations.
How exactly is "urgent data" defined and who decides which data has priority?
Hi,
I've read apple's Objective-C doc and am curious about using @synthesize. I've seen classes with a long list of @synthesizes and I've seen classes with one @synthesize then a long comma-separated list of ivars. So what's the difference between:
@synthesize ivar1;
@synthesize ivar2;
@synthesize ivar3;
and
@synthesize ivar1, ivar2, ivar3;
????
Hello,
I've recently read a lot about software (mostly scientific/math and encryption related) that moves part of their calculation onto the GPU which causes a 100-1000 (!) fold increase in speed for supported operations.
Is there a library, API or other way to run something on the GPU via C#? I'm thinking of simple Pi calculation. I have a GeForce 8800 GTX if that's relevant at all (would prefer card independent solution though).
Any hints are appreciated!
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?
Howdy, having a little trouble here.
I have domain.co.uk setting a session. When I click on a link on domain.co.uk to go to sub.domain.co.uk the session is not being read.
I have altered session.cookie_domain to .domain.co.uk not still not working. Is there anything else that needs changing?

i wonder what the difference between a library and a plugin is?
if a component creates a database (maybe comes with a .sql file or creates through a method) could it still be a library or is it called a plugin or module?
cause i am creating a address book component and it provides methods to insert and read records in database. i don't know if i should put it in library folder or plugin folder.
please shed a light on this.
thanks
In dojo, one cannot call a overidden superclass method outside of the same method in the derived class (for which there is this.inherited(), other than that one can call using class_name.function_name.apply). This feature is no longer there because of some refactoring and dojo guys are not going to put it back because they are not convinced about a good enough case for this. Please read this mail thread for details. Isn't there a good enough case for this functionality? Why or why not?
I am pretty proficient with C, and freeing memory in C is a must.
However, I'm starting a new C++ project, and I've heard some things about how you don't need to free memory using shared pointers and other things.
Where should I read about this? Is this a valuable replacement for proper delete C++ functionality? How does it work?
Right now I am going through MIT's introduction to Computer Science course via OpenCourseWare. As a part of this course I am learning the Python Language.
I've read a lot of things about the benefits of learning C. Before I dig any deeper into Python I wonder if I will be hindered or helped by learning Python first.
Do you think that I will develop any bad habits or anything like that from Python?
Hi I'm building an app in rails that needs to convert a twitter id into the twitter username. This is the code that pulls the id.
url = 'http://twitter.com/' + params[:username]
buffer = open(url, 'UserAgent' = 'irb').read
@vouched_user_twitter_id = buffer[/\d+(?=.rss)/]
How do I use that number to pull the username once i no longer have params.
Thanks!

I'm trying to implement my own IRC client as a personal proejct and I realized I needed a way to read and write from the socket at the same time. I realized I could have a reading thread which reads from the socket in the background and puts data in a queue and I could have another thread which writes data from a queue to the socket. However I have no idea on how to start with multithreaded programing or how to do it with c++. Where do I go from here?
I read in a file with a few numbers using a scanner, and then split them using the split method. My main issue is if there is a method that can just give me ranges, probably in the math class. The numbers are currently in an array, and I wanna move those numbers and there ranges into a two-dimensional array. Could anyone give me some tips or tricks to go about that?
Hello!
How do I know that I can safely upgrade Boost Serialization Library on a production system without breaking compatibility with the existing data ? Is there any test that I should perform in order to be sure that all data stored in the binary format by previous version of the library will be successfully read by the new one ? Does Boost Serialization library itself guarantee some sort of compatibility between versions ?
Is there a way to get the current version of ASP.NET MVC in code? Reflecting on MVC assemblies is needed? Any new IIS server variables? Some property to read in HTTP context?
in asp.net mvc , if i shove a dictionary or an array of objects in ViewData and read that in my view compared to creating a view model class that has that same data structure, is there a performance difference or other consideration or should i expect the same response time?
I am extremely confused as to how a JButton works. I have read over the oracle documents of the JButton, but I have failed to see how a JButton can have an actionlistener added to it. I have really always wondered how things like JFrames and all that can have things like .addMouseListener and all that. Can anyone explain how a JButton can have an actionListener added to it like the .addActionListener(...) syntax?
What does it mean to have fetchBatchSize to be the same as fetchLimit, say both are set to be 5. My understanding is that, with the fetchLimit, then only 5 records will be in the fetch result set; and additionally with the fetchBatchSize, only the ids/identities of the records will be read to the memory, and then the full records won't be retrieved until they are accessed. Is that a correct understanding?
I've read this question and the answers, but what isn't clear to me is WHO creates the "changes that do not appear in any parent".
Is it the git merge algorithm screwing up?
Or is it because the user has to manually adjust the conflicts to get the thing to build, introducing new code which wasn't in either parent?
Im using a code editor codepress in all of my textareas, but no textarea return a value. I think the different name and id is the problem. Example:
<textarea name="content_text" rows="20" cols="50" class="codepress sql" id="myCpWindow"></textarea>
I have read somewhere in here to use a hidden input to transfer the textarea's value, but i cant do it myself!

I am developing a game with Unity 3D and want to use custom code to get strings in the various languages I will be supporting. I've read articles about using the Android "res/values-xx/" directories (such as this page: http://developer.android.com/training/basics/supporting-devices/languages.html). If I do not store my translated strings in this way is there a downside? My main concern is whether the Google Play store may not know what languages my app is localized for.
i would like to use this syntax to update a table in access based on data from a txtfile.
fenton in his comments on this answer:
http://stackoverflow.com/questions/2992168/read-text-file-line-by-line-and-insert-update-values-in-table/2992337#2992337
said that this is possible and i would like to see the exact syntax please
Say I have a simple object such as
class Something
{
public int SomeInt { get; set; }
}
I have read that using immutable objects are faster and a better means of using business objects? If this is so, should i strive to make all my objects as such:
class ImmutableSomething
{
public int SomeInt { get { return m_someInt; } }
private int m_someInt = 0;
public void ChangeSomeInt(int newValue)
{
m_someInt = newvalue;
}
}
What do you reckon?
