Hi,
I am trying to come up with a way to develop all n-length permutations of a
given list of values. The short function below seems to work, but I can't
help thinking there's a better way. Not being a computer scientist, I find
recursive functions to be frightening and unnatural. I'd appreciate if
anyone can tell me the pythonic idiom to accomplish this.
Thanks for your help,

Hi, I am trying to find all lists of length x with elements a, b, and c.
To this end, I have created the class below, but it is not quite working and
I am having trouble figuring out what to change. Does anyone have any
insight?
class c:
def __init__(self):
self.traits = 4 # number of list elements
self.types = 3 # elements can be 0, 1, or 2

My first layout. I've got 2 divs, side by side, wrapped in a centered
div with a border. I don't want to use a float to get the
aforementioned divs to work side by side, so to get this to work, I
used a negative margin on the second div that was wrapped. Tried
absolute positioning, but that appropriately separates the second div
from the normal flow so the wrapper div doesn't keyline properly around
it. Is this the proper way to do this or...

I have a set of X items, but want permutations of length Y (X > Y). I
am aware of the permutation functions in <algorithm>, but I don't
believe this will do what I want. Is there a way, either through the
STL or some other library to do this, or do I need to write my own
code?

Does STL contain algorithms which generate (enable to generate) exponents, permutations, arrangements, and combinations for any

I have noticed that if a user closes a form via pressing return (either
while the OK button has focus or if AcceptButton is set to OK for the form)
then the "ENTER" keypress event fires ON THE CALLING FORM! This is very bad
for me, because in my application, Form1 responds to an ENTER keypress by
calling Form2. If the user closes Form2 via an ENTER, then Form1 just
reopens it again, kind of trapping the user in Form2 (they can still close...

I can't make this script work properly. I've gone as far as I can with
it and the rest is out of my ability. I can do some html editing but
I'm lost in the Java world. The script at the bottom of the html page
controls the form fields that are required. It doesn't function like
it's supposed to and I can leave all the fields blank and it still
submits the form. Also I can't get it to transfer the file in the
upload section. The file name...

What you have to implement
You have a message that can be sent on a port. Before sending the message you have to encode the
message to ASCII or Unicode as hexadecimal. Sending the message over the network as a continuous
string stream is quite simple. The recipient simply has to decode the hexadecimal string and will know
what the message is.
The problem must now be expanded as follows. Split the message in two and send it over the network...

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...
