I have successfully created a zip code radius search, but the performance is
unacceptable.
I have two tables. The first is 52K zip codes w/lat and long. The second is
3K national business addresses.
Using the zip code 10010, it takes almost 60 seconds to return 122
businesses within a 25 mile radius. This slowdown is almost entirely due to
the query radius distance formula.

I am trying to find a software that can find distance between two ZIP codes.
I think most of them do it by having the longtitude and latidute of each ZIP,
and substract. But this gives the air distance. Where can I find software that
find the ground distance (like in Mapquest).
Thanks,
Joe

I am trying to use the haversine function to find the distance between
two points on a sphere, specifically two zip codes in my database. I'm
neither horribly familiar with SQL syntax nor math equations :), so I
was hoping I could get some help. Below is what I'm using and it is,
as best as I can figure, the correct formula. It is not however,
giving me correct results. Some are close, others don't seem right at
all. Any ideas?

I used some of the excellent resources from DITHERING.COM for help in my
groveling newbie attempts to cough up working form validation....
I cut and pasted bits of code to check USA ZIP codes and CANADIAN POSTAL
codes, and merged them into one function that I called validCode. The
<form> tag has an onSubmit call to a general form-checker that works fine to
make sure all fields are filled. But within the form is a ZIP/POSTAL CODE
field,...

I am trying to make mailing labels. The zip/postal codes are 9 digits
(ex: 40601-0223) I ran a query and put in the input mask
00000/-9999;;_ and it works but when I make the mailing labels and it
pulls in the data the dash is missing (Ex: 406010223). Does anyone
know how I can get the dash to follow to the labels? I tried using
the wizard and I also built them manually. Any suggestions would be
appreciated.
Thank you,

Hello all,
I'm unable to figure out how to process the zip codes with regexes.
We have a custom component that takes a find pattern, a replace
pattern, and the input value, and will output the processed result
string. At the moment we're trying to clean up some zip code data
that has the following inconsistencies, for example:
99d999
99999d

Hello -
I need either a cheap tool or code & DB that calculates, eg. within 50-mile
radius of a zip code.
Anyone have any suggestions?

Hi
I want to add functionality to my site so that customers can type in a
postcode and we can tell them the "nearest store" in our database.
I have noticed there are loads of sites on the net that offer this
service but some of the them are small back bedroom sites. Do they
really pay for the expensive postcode data or is there an alternative
method you can use with some additional coding??

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...
