I need to use segregated free lists for a homework assignment and I was wondering if the STL or some other library had these already written so I don't have to reinvent the wheel?
I don't think STL has anything, but it looks like the Boost library might have it, http://www.boost.org/doc/libs/1_38_0/libs/pool/doc/interfaces/simple_segregated_storage.html
The STL implementations I've used support an allocator as a template parameter, which you could use to make a container use your segregated free list, but you'd still be writing your own.

how can I view the functions for the classes of the BOOST c++ library? I can't find them.....and I don't how I'd use anything from them if I don't know what I can use....
For STL there is http://www.cplusplus.com/
and example for STL vector:
http://www.cplusplus.com/reference/vector/vector/
for boost there is http://www.boost.org/doc
an example for boost vector

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 recently got interested in lockless programming and attempted to write implement a fixed-size mostly-lockless vector (github link). While it works, I'd love to get some feedback from more experienced people if my logic looks buggy or suspicious.
Are there any standard techniques that are particularly useful when testing out lockless data structures?
std::vector is lockless. In general, any good vector implementation will be lockless, because the granularity of a vector is too low for locks to be of any use.

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.

As you know, C++ allows multiple inheritance. But, would it be a good programming approach to use multiple inheritance or it should be avoided?
Thanks.
In general, it's not needed and can make your code more complex.
But there are cases where it's useful. As long as it's useful and isn't causing your code to become unmanageable, I see no reason to avoid it.
