This query is odd, it seems to be taking over a second according to my
log_duration logs and according to psql's \timing numbers. However explain
analyze says it's running in about a third of a second.
What would cause this? Is it some kind of postgresql.conf configuration
failure? I have the same query running fine on a different machine.

I am updating a utility to capture serial port data that was originally
developed as a DOS app using the outportb() and inportb() routines. I am
trying to re-work it as a Win32 app using Borland C++ 5.02, but am finding
that outportb() and inportb() are not available for a Win32 target. There
is no fancy flowcontrol or packet protocols being used, just simply
capturing incoming serial data.
What is available to me for such simple...

function a() { }
typeof a //returns 'function'

Hello, I am new to C and I am new to English. I not sure what palindromes mean. I don't know exactly what my teacher wants me to do. If someone could explain it to me in a different way that would be great. I know its sorta long, but maybe you only have to few the first few paragraphs.
Problem:
Write a program in C that generates number palindromes using the algorithm below (see 3. on the next page) and allows the user to try this...

I've compared some open-source javascript editors, and found different
techniques for constructing the code. Two examples:
CodePress.run = function() {
new CodePress(t);
}
CodePress = function(obj) {
self.initialize = function() {}
self.toggleLineNumbers = function() {}

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...
