Without using sequence generator How can we generate sequences in informatica mapping ?
Thanks
Well, like others said, I would have preferred to get a specific question on why you are trying to avoid sequence generator. Having said that, if i open myself to "the idea of an alternate" to sequence generator, some things do come to mind
If you have a relatively simplistic mapping, you can embed a oracle/db sequence.nextval call hidden in the source qualifier.
you can embed db/sequence call in a sql tranformation too. But know that it would be anti-performant.
you will be able to achieve a sequence generator behaviour using a persistent variable too, but there are limitations and downsides.
So, again, depending upon what you are trying to do and where you are getting stuck, you might want to repost/edit your question.. and perhaps get a more direct answer.

I am working on C++ on Linux.
I need to remove some duplicated code in two functions.
One function is for computing and another one is for logging.
There are some code that are duplicated in logging(), which is much longer than computing().
The duplicated code is distributed in logging() separately, which means that they are not just copy and paste from computing().
I need to figure out the duplicated part line by line, remove them and then replace the necessary results by passing them as parameters from computing() to logging.
Are there some efficient ways to handle this ?
Look at the functions side by side, identify common blocks of code, then factor these common blocks out into separate methods/functions.
It might not be worth merging them. If you really have to, though, perhaps one common function with an extra bool do_logging parameter.

I want to make a program that gets the information of a family including their names, SSN etc. I'm facing with two problems, firstly, what is the best data structure for this purpose,secondly, how should i get the information from the user, i mean when I'm getting info of father,i should determine his children, here is the problem.
how to connect his children to himself?
If it were me, I'd create a few different parallel arrays.
You're going to need to find out the algorithms for search through the arrays.
You're going to need to find out how to match them up together using the same index once the search finds a match. The index will probably be needed to be returned by reference to make things easier.
How to connect the children to the father maybe harder...
I don't know much about Binary Trees, we never talked about those in class. But that maybe the answer you're looking for. Sorry I couldn't be of more help. It's Christmas and it's 3AM lol. Good luck.

I am thinking which technology is needed for making copy of this web service: http://dziswieczorem.pl/
Does someone know any almoust-ready solution (especially for map-things) implemented in django?
Or maybe could anyone give me tips in which technology it would be easier to implement something like that?
To be more concrete:
Is there some ready template containing world map like on page that I wrote about above? I also need a chat feature.
For the map functionality, you may get some benefit from django-gmapi, but I've never tried it so I don't know if it's exactly what you want or not.
As far as chat, there seem to be a few options here that you could consider: http://www.djangopackages.com/grids/g/chat/

I am reading some introduction of an ancient Chinese game called Mahjong (a bit like poker but far more complicated). I have been spending couple days in writing a program to determine if a given hand is a win hand or not. Do anyone have any idea or know where can I find the free code for that? I only need the part to determine win/lose, I am not looking for the entire project. Thanks.
There is this cool Python library that can be used for scoring of a Mahjong hand given a situation. I know you are working in C++, but since python is highly readable, even to non-python coders, maybe you'll be able to copy/paste and edit the relevant part so you'll be able to use them.
Hope that helps you in some way.

Here's what I am trying to accomplish.
I want program1 to create a shared memory segment where I store various arrays.
Then, I want program2 to read in the arrays and modify them.
This sounds pretty simple, but for some reason, I cannot find a single example online that shows how this is done. Every example I have found uses a single program (e.g the initialize, read and write are both done by program1).
If somebody can provide an example here, I'm sure this would be hugely beneficial for pretty much everybody that wants to use IPC in C++.
Boost.Interprocess has a guide for the impatient.
