Hi,
Does anybody know where this term comes from?
"First-class object" means "something passable as an argument in a
function call", but I fail to see the connection with "object class"
or with "first-class airplane ticket". I just find the name a bit
strange. Also, if there are first-class objects, what would the
second-class objects or economy/tourist class objects be? :)

I have an Entry widget inside a Frame. The Frame contains other
widgets as well. I have bound the <Key> event to the Frame, but I
don't want the Frame to receive the event when the Entry widget has
focus.
So, I bound the <Key> event to the Entry widget (bound to method
a_key()). This works, except that both the Entry and Frame widgets get
the event. This also forces me to implement event handlers, which is
fine for the Frame since...

I am using a table to store temporary information. The application
frequently empties and reloads the data in the table from a table bound to
the table. The problem is, the app grows like crazy. I watched a 4MB app
grow to 987MB in one session earlier. I am hoping that someone might offer
a better method of doing this. Questions:
I am emptying the table with "DELETE FROM TempTable". Is there another
method of doing it that might...

Hello, I'm using tiny MCE plugin on my oscommerce and it is inserting my website URL when I use insert image function in the emails.
The goal is: Make it send the email with the URL http://mghospedagem.com/images/controlpanel.jpg
instead of
http://mghospedagem.comhttp://mghospedagem.com/images/controlpanel.jpg
As u see, there's the website URL before the image URL.

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....
Now, this would greatly impact the work of software developers. The idea...

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...
