There's lots of ways of representing a hierarchical data structure in a
relational database. These range from the trivially easy to implement in
PHP (adjacency list; each node has an ID and a ParentID) to the fairly
nightmarish (Tropashko's nested intervals).
In starting this thread I'm not looking for a primer on any of these
methods, which Google will happily provide; I'm looking to create a list of
PHP implementations of any such...

I am a basically a life-long Win32 C programmer specializing in high-end
winsock servers.
Before I dive into portable C++ programming, I wanted to code up an example
of what I thought would be a workable Collection template library. The idea
is to design API's that operate on interfaces, and provide
multi-implementations to that "single" API. C++ Interfaces and
Implementations, seems to behave like Win32 COM objects?

Seperate compilation (that's what it's called, right?) seems to be
quite popular, so I decided to get some info about it, and (d'oh) use
it...
But it's whole structure seems weird to me...
Here's what I think of how it is (from what I've read):

Suppose there is a 10,000 lines header file that wildly mixes definitions
(the interface) and implementations. Other code that includes this header
file takes hours to compile, and it's impossible to compile a shared
library from the header file, of course.
Is there a tool that takes this header file, and cuts out the
implementations, writing them into a separate .cc file? It would
automatically create a clean separation of interface and...

What is the purpose of a free standing implementation of C? stdio.h
isn't even included. I've only used hosted implentation.

Hi,
We see that C is a bit liberal towards non-standard syntax,
for e.g. when i tried
<printf("string1", "string2 %d", v1);> in Dev-C++, it printed string1
and no error was raised, is this the mistake of standard or the
implementation (Dev-C++).
I was under the impression that the implementations could have been
better by implementing proper rules and adhering to the standard (ANSI
C) at the same time, for e.g., in the above case i was...

This may be in the category of bush-league rudimentary, but I am quite
perplexed on this and diligent Googling has not provided me with a
clear straight answer--perhaps I don't know how to ask the quesion.
I have begun to familiarize myself here with the gcc compiler in a
win32 environment, in the form of MinGW using both Dev C++ and MSYS as
interfaces.
I have recompiled some old math code that uses long double types
throughout and...

I'm just beginning to learn C programming, after working for a while
with high-level languages. I am wondering if there is a standard set of
implementations for things like hash maps and linked lists that can be
used by C programmers. I took a look at the GNU C Library, but I saw
functions, not data structures. Do C programmers come up with their own
data structures, or is there a standard set that I can use?
Thanks for the help.

Some faster Python implementations are under development.
JPython has been around for a while, and PyPy and ShedSkin
continue to move forward. It's worth thinking about what slows
down Python implementations.
It isn't the dynamism, really. As others have pointed out
in the Python literature, most of the time, the more elaborate
dynamic features aren't being used for any given variable or
object. If code has something like "x = 1.0",...

Some recent posts got me thinking about how one might have dealt with
simplistic malloc() implementations which might return NULL for a 64K
request but might accept two 32K requests or four 16K requests. (I'm
assuming, perhaps incorrectly, that quality modern implementations
will coalesce free space as necessary and if possible to satisfy
requests.) I came up with the following (compilable but untested)
first cut at code to try a...
