In an interview at http://acmqueue.com/modules.php?name=Content&pa=showpage&pid=273
Alan Kay said something I really liked, and I think it applies
equally well to Python as well as the languages mentioned:
I characterized one way of looking at languages in this
way: a lot of them are either the agglutination of features
or they're a crystallization of style. Languages such as
APL, Lisp, and Smalltalk are what you might call style...

Hi all,
I'm trying to write a special adaptor iterator for my program. I have
*almost* succeeded, though it fails under some circumstances.
See the for-loop in main().
Any pointers/help would be muchly appreciated.
Apologies for the long post - I couldn't find a shorter way to

If I were to design my own container and its iterators, I understand
that I need to provide both "iterator" and "const_iterator" so that
begin() and end() return appropriate ones depending on the
"constantness" of the container object. I also note that is it done
through overloading begin() and end() like below:
iterator begin();
const_iterator begin() const;
So it seems to me that I need to have two separate iterator classes

Hi all,
I tried looking this up in the sgi docs but it didn't provide any concrete
answer to what I'm looking for. Basically, is there any difference between
using ::iterator for a container vs using ::pointer?
I did a quick experiment and replaced all the ::iterator in my code with
::pointer and it seems to work the same. What I'm think is on the surface
they're the same but perhaps there're some subtle differences beneath the...

I am trying to write an iterator for a std::set that allows the
iterator target to be modified. Here is some relvant code:
template <class Set> // Set is an instance of std::set<>
class Iterator
{
public :
typedef typename Set::value_type T;
typedef typename Set::iterator SetIterator;
Iterator(Set& container, const SetIterator& it);

is the following code standard? (cleanly compiles under g++-4.0.2):

int main() {
int arr = {1, 2, 3};

Hi, there
Assume that I have three vectors x,y and z that has the same number of
elements. Can I use a common iterator for these three.
I did it with iterx, itery and iterz but the thing I wondered was: in a
for loop you can write array elements by using the same index such as;
for (int i = 0 ; i!=10; ++i )
cout << x << y << z << endl; Bu

Ok, this should be fairly easy for most of you (at least I hope so),
but not for me:
Let us say we have got the following elements:
std::vector<Entry> models; //Entry is a struct
std::vector<Entry>::iterator modelIterator;
In a method, I am currently writing, I need to get a pointer to an
entry in the vector.. I thought of the following:

I'm sure this is not a new idea, but I have never heard about it
before. I'm wondering if this could work:
Assume that you have a common base class and a bunch of classes
derived from it, and you want to make a deque which can contain any
objects of any of those types. Normally what you would have to do is to
make a deque or vector of pointers of the base class type and then
allocate each object dynamically with 'new' and store the...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp
Here is the code in...

Overview:
Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

Hello
I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
