I'm just rewriting some backend management pages, in fact rewriting the
whole database too. One of these pages has a simple HTML form to edit
existing rows. I don't want to populate the form beforehand with all
existing data. I just want to check which of the 20 fields have changed and
update the data accordingly.
Before (I wrote the script years ago, forgive me!), I just had a check
whether any data in each field and each had its own...

The Python slice type has one method 'indices', and reportedly:
This method takes a single integer argument /length/ and
computes information about the extended slice that the slice
object would describe if applied to a sequence of length
items. It returns a tuple of three integers; respectively
these are the /start/ and /stop/ indices and the /step/ or
stride length of the slice. Missing or out-of-bounds indices
are handled in a manner...

What's the best (i.e. fastest) way to find out if an array contains a given
value? Other than looping, the only way I know to do it is to use an
associative array/hash instead....
Is there a better/faster way?
I.e if I have a list of names, what's the best way to find out if the aray
contains "jane"?

Hi,
first hello, I am new to the list, and I guess my question will show
that clearly.
I want to use some vector operations (at the moment altivec) in
existing code. It is a raytracing-based application, and for now, I
would like to replace the operations on my data type vect3 (which is a
float array) by operations on a vector float. The vect3 is simply a
typedef to an array of floats so far.

I would like to know if there's a quick "Linq" way to find the index
of an array having a particular value. I can do this the long way by
sequential iteration, but would like to know if there's a shortcut.
Specifically, you have an Array, say an array of Ints. You have a
maximum value, i.e. int someValue = Array.Max(); and you would like to
know which ith cell of the Array holds this value.
How to do this without iterating the entire...

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...

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...
