Hi,
I have a c++ program that creates hundreds of thousands of objects.
Eventually, we would like to be able to create millions, but memory is
limiting us. For example, 125,000 objects currently takes up 286 megs of
memory.
This leads to a couple questions...
First, do accessor functions take up space? Are there certain tricks that I

Given A, B and C
I would like to calculate the sum of each entry:
A=B+C for each i,j
The easiest way is to use for-loop, but I think the performance is not good.
Is it possible to find out some faster way to do that?
Thanks.

Hi,
I've read that the if/else statement, or get/set accessor, can be
compiled inline by the C# compiler if they are small enough.
Have you seen any documentation that 'summarized' all thoses
optimizations tricks? I would like to be aware of all tips and trick
that should be used as good programming habits that make any software
coding optimized. I remember that in VB6 there was a lot of
optimization tips.

Hi!
I have a canvas. In this canvas I need to paste 512 8x8 bitmaps every 1/10 of a second. Currently I use something like this : canvas.create_image(posx, posy, image=img). However, Tkinter is apparently much to slow to do this. Is there any obvious optimization tricks im missing out on?

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,...

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....

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...
