Hello,
I am beginning to work on a fairly large project and I'm considering to use python for most of the coding, but I need to make sure first that it is reliable enough.
I need to make sure that I won't have surprises when my program runs on different real-world systems. So far I wrote a little script with python using urllib, and on one computer it failed completely because of a problem in getting the proxies (in my opinion this is a...

I did it.
I proposed python as the main language for our next CAD/CAM
software because I think that it has all the potential needed
for it. I'm not sure yet if the decision will get through, but
something I'll need in this case is some experience-based set
of rules about how to use python in this context.
For example... is defining readonly attributes in classes
worth the hassle ? Does duck-typing scale well in complex

Hi,
I am trying to execute some code compiled by g++ on Linux and have
found that after some time, the program allocates a huge amount of
swap space (250MB on my machine which has 512MB physical) and (700MB
on another server with 1GB physical RAM).
I have used vmstat to trend the amount of swap and observed that the
memory is not being "thrashed" and there is simply a large amount of
data that has been swapped out. This still slows...

Hello,
Say I have 1000 text files and each is a list of 32768 integers.
I have written a C program to read this data into a large matrix. I am
using fopen in combination with fscanf to read the data in. However, it
takes about 20 seconds to complete and I wonder if there is a faster way.
For example, I found that I could use 'fread' to read the data into a
string that looks like this:

Currently our desktop application is a large VC++ 7.1, Unmanaged, MFC
application.
We are going to be re-architecting our application and we are considering
rewriting it using C-Sharp.
So far, we have written a few pieces of our program in C# that get called
through a managed DLL. But they are used infrequently so the impact on
performance has been minimal. We wrote these pieces in C# because it was
easier to do in the short amount of...

OK, I don't know if this is Off-Topic for the group(s), because "QT" isn't
"Pure C++", and Slackware is a distro, but those guys are sharp. :-)
And I've crossposted to sci.electroncs.design because I can. ;-P
Anyways, I want to crow about what I've done. I've been dabbling, kind of
poking away at the QT tutorials, but when I get to the "Now, write some
C++ to make it all go", I kinda hit a railroad crossing. ;-) So, I

How does C++ safely open and read very large files? For example, say I
have 1GB of physical memory and I open a 4GB file and attempt to read
it like so:

#include <fstream>

using namespace std;

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...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.

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...
