I have a database of zipcodes with latitude and longitude. I also have the
method of calculating the distance between two zipcodes. What I want to
know is if there is an efficient algorithm for obtaining the zip codes
within a specified distance of the first zipcode without having to retrieve
and calculate for every record in the database.

Hi,
I needed a method to determine if a point was on a line segment in 2D. So I

which turned out to be incorrect and incomplete but by modifieing it would
still be usuable.
The first method was this piece of text:

I am just trying to decide whether to split my code and uses code behind. I
did it with one of my pages and found it was quite a bit of trouble.
I know that most people (and books and articles) like it because you can

I must create a routine that finds tokens in small, arbitrary VB code
snippets. For example, it might have to find all occurrences of
{Formula}
I was thinking that using regular expressions might be a neat way to solve
this, but I am new to them. Can anyone give me a hint here?
The catch is, it must only find tokens that are not quoted and not
commented; examples follow

In this code, I tried to kill my thread object by setting a variable on it
to False.
Inside the run method of my thread object, it checks a different
variable.
I've already rewritten this code to use semaphores, but I'm just curious
what is going on.
Here's the code:

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...
