New to Python... trying to figure out how to count the objects in a list
and then map the count to the objects or convert the list to a dict... I
think the latter would be better as I need a number associated with each
entry. Any pointers?
Also, does this bit of code look to be truely random?
def random_number_gen():
winner =
winner.append(random.sample(xrange(100000), 1))

I am using method 'a' below to pick 25 names from a pool of 225. A
co-worker is using method 'b' by running it 25 times and throwing out
the winning name (names are associated with numbers) after each run and
then re-counting the list and doing it all over again.
My boss thinks that 'b' is somehow less fair than 'a', but the only
thing I see wrong with it is that it is really inefficient and ugly as
it's doing manually what 'a' does...

Dear cpp-ians,
I want to apply a stratified sampling on an image. Following simplified
example will explain my problem.
The original image I with nrows and ncols is now a vector V of length
(nrow x ncol) and every element of the vector contians its pixel value.
vector float V ;

I'm using radnom selection in ms access to select certain number of
questions for the exam. i have two versions of the report:
- one without marked answers
- one with marked answers
the problem is when i generate the reports one after another, i don't
get the same selection of questions. Does anyone knows how to generate
two parallel reports that would give the same random selection?

I want to randomly select some files from a source directory & copy them to
a target folder for testing. How can I select files from the source
directory randomly?
I have thought about getting a count of the total files in the folder & then
using a random number generator to select files based on count. Is there
another more efficient way of doing this, something that doesn't involve
generating a random number?
thanks!

I need the random.sample functionality where the population grows up to
long int items. Do you know how could I get this same functionality in
another way? thanks in advance.

does
x.sort(cmp = lambda x,y : cmp(random.random(),0.5))
pick a random shuffle of x with uniform distribution ?
Intuitively, assuming list.sort() does a minimal number of comparisons to
achieve the sort, I'd say the answer is yes. But I don't feel quite confortable
with the intuition... can anyone think of a more solid argumentation ?

I need to implement a "random selection" algorithm which takes a list
of as input. Each of the (obj, prob) represents how
likely an object, "obj", should be selected based on its probability
of
"prob".To simplify the problem, assuming "prob" are integers, and the
sum of all "prob" equals 100. For example,
items =
The algorithm will take a number "N", and a list as

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...

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...
