there seems to be a maximum size (in px) for images created with
imagecreatetruecolor (somewhere between 4000 px and 4500 px). if the
image is bigger than that size, the browser doesn't display it but
reports errors in the image.
is this maximum size inbuilt into php?
or
does it depend on my server config and if yes how can i read it?

What is the maximum size of an array? I tried to edit an extremely large
array for a magic square, for example, array, and when I ran the
program, it would not display the array. I changed the array to 105 by 105
and it worked fine. Does anybody know what the problem is and how I could
possibly get around it?

Dear,
C++ is currently a dominant programming lanaguage to solve
Combinatorial Optimization problems. Will other languages be able to
compete with C++ in this field?
Could you suggest some C++ libraries for Combinatorial Optimization?
It is probably that a library will address a certain problem, e.g.
Max-Cut, TSP etc., that would already be fine.
Thanks and warm regards,

the following C++ program seems to yield a segmentation fault

I am trying to build a Pyrex module on Mac OS X version 10.3.9 (don't
know which big cat that is). It already builds fine on Mandrake Linux
and Windows XP. I have one source file where gcc hangs if given an
optimization setting of -O2 or -O3, but a level of -O works fine.
Can anybody suggest an approach to debugging this? I'm comfortable on
Linux but I can't find my way out of a paper bag on a Mac.
Also, is there a Pyrex or distutils...

Hello,
does a String in C# have a maximum length?
I tried to write a ToString Method of my class containing a hashtable.
At the beginning of the method i defined a String "ret".
In every iteration of my hashtable I add the content with ret += "...".
After some time my programm crashes.

Hi all,
I'm getting an OutOfMemoryException when I initialize a byte array in
C# like this:
Byte test = new Byte;
I'm using ASP.NET 2.0. In ASP.Net 1.1 it works fine. So what am I doing
wrong?

The task is to solve a constrained optimization problem in C/C++.
Computational
Time is of high priority. One approach can be to use ready functions
in a "free ware" Optimization Library (if available). If any one of
you have any idea about such library please inform me. I am dealing
with Constrained Optimization for the first time so please guide me
How I should solve this problem. I will appreciate suggestions from
you.

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

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,...

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. I'm particularly interested in Zigbee because I've heard it does some...

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
Now, this would greatly impact the work of software developers. The idea...

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
