Hello
Evidently is possible to have a negative time interval:
clapidus=> select interval '-1';
interval
-----------
-01:00:00
However, there seems to be no provision to get the absolute value in such

I'm trying to compute the absolute value of an integer using only bitwise
operators...
int x;
sscanf( "%d", &x );
printf( "%d\n", (x^((~((x>>31)&1))+1)) + ((x>>31)&1) );
That works, but it assumes 32 bit integers. Is there a portable/standard way
to do this? Or are ANSI integers always 32 bits? If not, is using
sizeof(int) * 8 - 1 as the shift value an acceptable alternative?

Hi all.
Here is a problem. I want to sort a form by absolute value. Let's say, if I have a field named "theSum", I'd like to set the form OrderBy property to "Abs()". If I use "Advanced filtering\sorting" from "Records" menu, it works just fine, and OrderBy proprty becomes "Abs()". But when I do the same thing manually or programmatically, it doesn't work.
So I cannot figure out what is the trick here and how to make this work.

I really don't understand how something like..
#define abs(x) (((x) < 0) ? -(x) : (x))
could cause a possible overflow.

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,...

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...

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...
