Is it possible to override the to_sentence method just for one model in my rails application?
More generally, how do I modify methods for an Array of my models?

Hi,
I have resize images exceeding a max size. Methods I tried so far are not good enough :-(
System.Drawing.Image.GetThumbnailImage generates very poor quality images in general.
Playing with options like this one I can generate better images in quality but heavier than the original one.
Probably the second option (or something similar) is the best option and I would need to resize using the proper options.
Any advice?
Dear all,
I've recently been playing with Hadoop. I have a six node cluster up and running - with HDFS, and having run a number of MapRed jobs. So far, so good. However I'm now looking to do this more systematically and with a larger number of nodes. Our base system is Ubuntu and the current setup has been administered using apt (to install the correct java runtime) and ssh/scp (to propagate out the various conf files). This is clearly not scalable over time.
Does anyone have any experience of good systems for administering (possibly slightly heterogenous: different disk sizes, different numbers of cpus on each node) hadoop clusters automagically? I would consider diskless boot - but imagine that with a large cluster, getting the cluster up and running might be bottle-necked on the machine serving the OS. Or some form of distributed debian apt to keep the machines native environment synchronised? And how do people successfully manage the conf files over a number of (potentially heterogenous) machines?
Thanks very much in advance,
Alex
I write a python class which makes asynchronous method calls using D-Bus. When my reply_handler is called, it stores data in list. This list can be used by another class methods at the same time. Is it safe or I can use only synchronized data structures like Queue class?
I have this list

Anytime you click on an image extra content appears . I have tryed several css methods but i cant get the images to remain in their position and get the text to go underneath . Anyone has a solution ?
I need to divide a scene in to two layers. So that I can write same methods for two layers.
So I may get two functionalities. But can I make that ? Is there a possibility in cocos2d?
Thank You

I have a domain blah.com that was aquired a while back by my company foo.com. I set up a two way trust between the two domains, but now I want to move their servers into our forest, while keeping the domain name of blah.com.
Is this possible?
What things do I need to consider when doing this?
I know I can't move the domain from its forest into our forest.
blah.com is a 2003 native domain/forest
foo.com is a 2008R2 domain/2003 forest.
To use methods of a class I need to instantiate a class. At the moment the class has not constructor (so I want to write it). But than I have realized that the constructor should do nothing (I do need to specify values of fields).
In this context I have a question if it is OK to write constructor which does nothing. For example:
public Point() {
}

Does anyone know of a good (read: quick to code) method for converting DTOs to View Models or mapping DTO members to View Model members? Lately I've been finding myself writing many conversion and helper methods but this is a very arduous and tedious task. Moreover, it will often needs to be done twice (DTO - View Model, View Model - DTO).
Is there a methodology, technique, or technology which would allow me to do this more quickly and efficiently?

I have a big table with vertical scroll bar.
I would like to scroll to a specific line in this table using jQuery/Javascript.
Should I look for plug-ins for this task, or there are built-in methods ?
Here is a little example to play with.
Thanks a lot !

I have tried updating my VGA driver but its doesn't helping me much.
Is there any way to solve this problem ?
1if i want to replace monitor what maximum resolution should i buy ?
2if i want to upgrade(graphics card/motherboard) my desktop what is the minimum configuration to support the current system.
Thanks in advance
As someone who is interested in learning more about the security side of technology, I ask you all the following questions:
How is it that crackers crack software? What techniques are used to do so? I would imagine that the cracking methods depend upon the language the software is written in, right? Aside from using something like cloud-based security for SaaS ((software as a service) which isn't always an option), what choices does one have to prevent their software from being compromised?
I woudl like to know how to use a System.Collections.Hashtable in F#. The reason it is a Hashtable is because I am referencing C# assemblies.

- Get value from key
I have not been able to find anything useful in google about this. Any help would be appreciated.
Thanks
I'm using GitHub for code and Heroku for the deployment platform for my rails app.
I don't want to have sensitive data under Git. Such data include database file settings (database.yml) and some other files that have secret API keys.
When I deploy to heroku, how can I deal with files that are not under revision control.
When I use Capistrano, I can write some hook methods, but I don't know what to do with Heroku.

I recently ran across several objects implemented to handle events with a hard coded mapping using this pattern:
public void handleEvent(Event event)
{
if(event.getCode() == SOME_STATIC_EVENT)
doSomething(event);
if(event.getCode() == ANOTHER_STATIC_EVENT)
doSomethingElse(event);
}
where doSomething functions are implemented as methods of the same class.
In hopes of striving for looser coupling, how would you suggest abstracting out this pattern? Also, what's the best approach for mapping 0..N functions to a fired event?
I have a small network with a single LinkSys router connected to broadband in US via Comcast. I have a VPN proxy server account that I can use with a standard Windows connection, allowing me to have a geographic IP fingerprint in Europe, this is useful for a number of purposes.
I want to setup a 2nd router that automatically connects via VPN to this proxy service, so any hardware that is connected to router 2 looks as though it is originating network requests in Europe, and any hardware connected to my main router has normal Comcast traffic (all requests are originating from USA).
My 2nd router is a LinkSys WRT54G2, I'm having trouble getting this configured. Question, is what I'm trying to do even feasible? Should the WRT54G2 be able to do this with native functionality? Would flashing it with DD-WRT allow me to achieve my objectives?
I have 2 lists in my program one that store objects of type student and another one which stores objects of type marks.
I have 3 methods one that inputs the details of the students, one that inputs the marks and one to view student details and their marks. My question is how I can use a hash table to get the Id of a student and then use it to input the marks and then how to retrieve both the student details and their marks altogether.
Please help me if you can.
I am doing some input/output between a c++ and a python program (only floating point values) python has a nice feature of converting floating point values to hex-numbers and back as you can see in this link:
http://docs.python.org/library/stdtypes.html#additional-methods-on-float
Is there an easy way in C++ to to something similar? and convert the python output back to C++ double/float? This way I would not have the problem of rounding errors when exchanging data between the two processes...
thx for the answers!
