After years of coding all of a sudden I got a paper on "Authorization in instant messengers" to write. While creating a messenger and the authorization system isn't that big a deal, what can be written about it? It needs to be around 50 pages :/

If someone could help me out with creating the "framework" of that paper that I could fill with data, it would be great.


PM me if you feel you could do the whole thing. I'm sure we can reach an agreement. ]]> Computer Science mashimaro http://www.daniweb.com/forums/showthread.php?t=201795 Sat, 04 Jul 2009 17:39:32 GMT What is evolutionary computing? where can find more information on this.

In many OOP languages "this"(or something similar) is used to point to current object. But i think its an object by itself. Here is what i found" polymorphic object which can point in different times to different object`s types"
I like to get some more information about this maybe some science article.

I have found 2 approaches in Object Oriented programming:

1. Creating a "master" class that contains all classes, and creating a method for each operation. (With this approach you only have to pass the "master" class throughout different GUI screens)
2. Using only the classes you need in the GUI (Then you have to see you pass through the appropriate classes)

I find that both approaches have their pro's and con's.
Using only the necessery classes fits my idea of OO better, but I'm not sure cause, well, as said, using a master class has it's advantages too.

If necessary I'll try to give some more specific pro's and con's, but I'll leave it to this for now.

What do you all think about this?

Thx in advance

I have some questions
1-Is an API just a set of functions that let you do sth easier that using the things that make up the API,directly?If yes so and API must be able to be compiled in every IDE but you can see that Qt's API needs its own IDE to be compiled?
2-How language independent APIs work?Does it mean that with having the API,you can use it in any language?
3-From the definition of ABI in wikipedia,I understood that they are used to make the communication between softwares easier.Is it right?If yes,how can I implement that?

I joined a company on 1st of June and I am going to get my 1st month salary. And the one responsible for this to happen is my sister. She after finishing her BE-computer science from one of the reputed colleges in Tamil Nadu,INDIA joined a customer support services and she took the burden of my family's poor fiscal condition. She is still working there with no willing to work. Her aim is to become a developer. Now I can support my family and I want my sister's dream to come true. I want to know which course in which training institute will help here to reach her goal. I want your help to figure out a course that covers programming languages and technologies that are used now and will be used predominantly in future and a perfect IT training institute that provide 1st class training and placements. The major reason going for an IT training institute is to find her a developer job within 3-6 months. So please advise me a course that falls inside this time limit and a Training institute in Chennai. I suggested my sister to do a course that covers JAVA and WEB technologies since next generation will be ruled by internet and do it in NIIT. I am not confident of my suggestion to my sister since I am a fresher to IT industry I am not that sure of the future. So help me to show my sister a right direction. ]]> Computer Science auhuman http://www.daniweb.com/forums/showthread.php?t=200703 Tue, 30 Jun 2009 12:33:14 GMT I have a final project coming up....I have been thinking of ideas about e-learning with voip, a house security system with electric power monitor, and an inventory and sales system with travel logs through sms.

Is there any possibility that result will be equal something other then 2 afterwards?

If you want a more concrete example I ask this question because of a project I'm working on. Basically I'm simulating a network of neurons and I want to distribute the neurons among multiple threads so it runs faster.

Every thread is responsible for it's own group of neurons and at each time step of the simulation all threads calculate the voltage of their neurons and see if any neurons have exceeded a threshold, then they run into a barrier and wait for all the threads to catch up.

Then the voltages of any neurons connect to the neurons that exceeded the threshold are then added to or subtracted from depending on the strength of the connection. It's this step I worry about because two threads could try to change the voltage of the same neuron at the same time. I think I know a way around this but I wondered if things are fine the way they are, since the threads are adding or subtracting values as opposed to assigning values.

After this the threads run into the same barrier as before and wait for each other before starting the next time step. ]]> Computer Science OffbeatPatriot http://www.daniweb.com/forums/showthread.php?t=200270 Sat, 27 Jun 2009 21:19:57 GMT There is a computer with 1 GB of physical memory and a triple layered mapping system (The top layer table consists of one page).
