hi folks
i need help in designing my mongoDB schema
So there is a user modal with basic user info (name ,email,password)
Now i need to make another modal called batches including info like (batch name,no of users)
I am getting confused on how i relate them like
i also have to maintain the plan that perticular user has taken eg 30days or 9days etc
A user can take multiple batches and have different plans according to the batches

[idle dew]

HEY!

should i upgrade to win11 ?

[tribal ore]

probably not

[idle dew]

any particular reasons?

[tribal ore]

i mean... first of all it looks kinda bad (tho its just my opinion), from what i understood many things changed, rather than relearning windows i'd say learning another os would be cooler (or just staying with windows 10), i see it as shady (primarily bc its proprietary and i see everything as shady) but umm.. yeh thats it... also.. why yes lol

[red hare]

still need help?

[red hare]

does it output anny error code?

[static smelt]

hi, i need help with the implementation of a minimax algorithm
more specifically, how do you store the move with the best evaluation?

[red hare]

wikipedia explains this pretty well

https://en.wikipedia.org/wiki/Minimax

[vale aspen]

anybody work in MySQL Workbench

[static smelt]

sorry, it's not the theory i dont understand, it's specifically the way the move is chosen from a list of moves after finding the best score

[red hare]

Just set the current move to the best move found

and let the algorithm run

updating the current move as you go

[static smelt]

hi, sorry, how would i go about traversing back to the parent node of the best move?

[red hare]

keep the best move stored in a variable

so that way you have a current_best and a alltime_best

so that way you never lose the best option you found

[static smelt]

hi dude, im using engineAnswer as alltime_best and bestMove as current_best but im still unsure of where to put the lines of code to store them

the recursion is messing with my head

[red hare]

What's the issue with that code?

Oh wait

You need to compare the moves in the end

You only want to update the all time best move if it's worse than the best move found

The way you are doing it, it will always update to the best move found regardless of what the best all time move is

Is this intended?

[static smelt]

no, it's what i have tried and failed

[red hare]

well you just need to add a line of code that compares both moves

[static smelt]

where would this be?

[red hare]

would look something like this:

(pseudocode)
// after the for each loop
if(eval_move(AllTimeBest) < eval_move(currentBest)) {
  AllTimeBest = currentBest;
}

this would replace the line you have after the for each loop that assigns the move to the all time best

[static smelt]

ok, i'll try this, i appreciate the help greatly

Hey guys anyone familiar with python’s basics?
I’m in desperate need for a helpp

Q1
“Write a python code to get a sub list that contains even numbered index values of a given list. Assume that L= [5,10,15,20,25,30], output should be: [5,15,25]. the code should works with other lists too, for example, if L=[3,5,8,13,18,21,23,25,29] your code should generate [3,8,18,23,29] as output. “

Q2
“Suppose you’re given a tuple by the user, in the first input line. This tuple should contain only integers. The user has forgotten one of them and used a “?” string in place of it. After remembering the value of this integer, in the second line of the input he enters a two tuple. The first number is the index of the “?” And the the second is the integer value that is going to be substituted in place of “?”
You’re expected to fix the original tuple with this later information and print corrected tuple

Sample run:
Enter your tuple: (1,2,”?”,4,5)
Enter your index and missing number: (2,3)
Your tuple is now: (1,2,3,4,5)

[remote elbow]

yes sure

I'd like to ask how I could put the paragraph higher

it doesn't matter in which sequence I put paragraph btw

PS: I'm new, so please don't be too harsh on my code😅

[strange zodiac]

For me I would put all your 2 divs into 1 div

In your css I would use the attribute display: flex

Name that new div like container or something

With display flex you will be using other attributes like align-items and justify-content

[remote elbow]

you can give avatar class a property of display:block; (in your css code)

[nimble sparrow]

thanks a lot!

both of you

[potent scroll]

@rotund pond i wrote something like this, i hope it will be helpful
Q1:
numbers_list = [1,2,3,5,8,11,10,7,9,20,6]
even_numbers = []

for number in numbers_list:
if number % 2 == 0:
even_numbers.append(number)

print(f"Even numbers: {even_numbers}")

Q2:
my_tuple = input("Enter your tuple: ")
my_tuple = my_tuple.split(" ")

print("Your tuple:", my_tuple)

edit_num = input("Enter your index and missing number: ")
edit_num = edit_num.split(" ")

my_tuple[int(edit_num[0])] = int(edit_num[1])

print("Your tuple is now:", my_tuple)

That’ll also definitely helps; I really do appreciate it!!

[open solstice]

It depends on what you wanna do, but in practice it'll be fine yeah

god I hate frontend

[idle dew]

Well, I'm pretty interested in programming softwares, apps etc.

[void halo]

So Python is a great language to learn in general. But when it comes to this response of "I am interested in programming software's, apps, etc.." there is a lot more questions that you need to personally answer here. Like for example, I work as a AI Research Engineer so I use Python as my everyday language currently. But in my previous role I was a Backend SWE so knowing a programming language was good but knowing JavaScript was critically important as that was the language that I was going to be using for my day to day work developing API's.

All in all, learning any programming will set you apartment from the rest of the pack. But ensuring you know where your programming interest aligns and learning the languages associated with said interested I believe is critically if not the most important of them all. So for you if you want to do apps, a question that needs to be answered is what type of apps would you like to work. Would you like to work with ioS or android apps?

Again I just want to make it clear that Python is still a good first language but also think about your long term goal as Python will get your foot into the door but than from there where would you like to go is my point.

[fickle creek]

is there anyone who can help me installing kali linux in win10

i have seen options like vmware , wsl , dual boot .
dont have much knowledge about that . but want to try linux

also it would be very much helpful if there is anyone doing animation works
i would like to get the resources , i am pretty much interested in that side . but not sure where to get the infos or resources as youtube stuffs are pretty scattered

[nova basin]

depends and i would say find ur own language. if u like and easy to understand python then go on.

[idle dew]

depends on what you want to do tho. I would recommend you check the University course details and then learn the language they would teach before hand

I am studying CS now and we r learning 2 languages: C and Java. I am learning python too (self-study)

if you want to do data science or math or something then yeah i’d recommend you do Python.

[open solstice]

I personally recommend starting with java

[idle dew]

could anyone help me with my mac?

[open solstice]

it's better to mention the problem

[idle dew]

oh thanks a lot but i've already fix it

[small python]

IMO the answer is no, if you want to study CS or any other major related (Software Engineering, Computer engineering, etc) avoid python as your first approach to a PL. Python is amazing and it offers a lot of widely used features that makes everyone life better, BUT it also makes you feel that PLs are easy bc it is at a quite high level of abstraction that is hard to find in any other PL. If you want to learn seriously a PL start with C or C++, when you feel comfortable with whatever of those you can learn then Python, Java, Go, Swift, Haskell, almost anything because you have a solid base. That's it and good luck!

[idle dew]

So basically, just so you guys know, the specialised substances (they might help) of my high school are as follows : PC software
Programming, Web applications, Operating system, Computer networks, Application software, Office software, Multimedia, Graphic Design, Economy, IT specialization

And tbh, I really want to know if it makes sense or if its worth it to study any PL before high school

[small python]

it makes sense to me, but learning is always valuable, no matter what

IT is based on curiosity and learning skills so you never going to end that journey bc technology is always reinvented itself

or this https://man7.org/linux/man-pages/man1/type.1p.html

[thin hound]

A good start into programming? Yes. A good start for computer science? No, but with the caveat that it is a good tool to find motivation to get into CS, but it will allow you to develop a bunch of bad habits, and doesn't give you much understanding of what is going on under the hood. It depends on what your goals are.

[slate mantle]

I have a basic question about the for loop in python can somebody help?

[quartz lantern]

maybe

[slate mantle]

https://youtu.be/rfscVS0vtbw?t=10705

so I'm currently learning python from this guy on youtube and on this section he was writing a simple code that turns every vowel into "g".

what is confusing me is that he didn't give the variable "translation" the value of the variable "phrase", yet the code still worked and I'm not sure why?

I assumed it would be something like

if letter in "AEIOUaeiou":
translation = phrase + "g"

[open solstice]

if you do that, when it hits inside the if statement the output would be ''To be or not to beg'', and the previous value of translation will be gone

basically what he does is updating the string assigned to translation

it works like
"T" is not in the list, so translation = translation + letter => "" + T = "T"
"o" is in the list, so translation = translation + "g" => "T" + "g" = "Tg"

and so on

[slate mantle]

ohhhhhhhhhhhhh

that makes sense thanks. I previously ignored what was happening under else for some reason😂

[open solstice]

no worries

it's better to think line by line with an example when you don't understand something

[slate mantle]

that makes sense, it's just ever since he started explaining functions I got confused for a bit

Hey, does anyone use the languages scheme

[flint olive]

This video will answer your questions!

[cyan jungle]

THANKS GUYS

[tepid salmon]

start small. First watch some videos about how to start, then google a bit. If it's okay for you, take a course on Coursera or on another platform or continue with youtube channels (Hackersploit is a great one to start!). But rather than only focusing cybersecurity materials, learn one of c programming languages, java and etc. You need to think on objective, 3rd person side. I think that's pretty much it to give you boost to start. Don't search too much. Just focus on starting and eventually you will start to guide your own roadmap. Good luck!

Hey. So I am gonna be taking data structures and need some advice..

[steady mason]

How can i print s to show me numerical values as answer? Like fx [0, 5] and [0, 10]?

[silver notch]

I think from what I remember from Jupyter you should execute everything in one box

I mean every “box” is running indipendently and based on results from before

So if you ask to print s it obviously shows you what is the value memorized in the kernel from before

I don’t know how I can explain well cause I have lost hand with python and jupyter but

Used Jupyter a few years ago in my Operation Research lab

[open solstice]

what are the sizes of aDeck and bDeck?

when you initialize them

[thin hound]

I don't think this for-loop alone should cause any segfaults, the logic seems good

assuming you initialize aCount and bCount to 0

sure

yeah, that's a headscratcher
I don't know a lot of C++, only C, but I can't find the error. I'd suggest printing aCount and bCount to make sure they really are 0, and you could also try to do the for-loop only up to 50 or something, and check if you still get a segfault, as cases like these often are off-by-one errors. Also, I'd try to compile in debug mode if you haven't already, and your compiler supports it.

you could even extend the size of aDeck and bDeck to 27, and if that works, it's an off-by-one error

[open solstice]

this thing gives me assembly headache

at which line do you get the error

debug it line by line

[thin hound]

i suppose you could try

int foo = aDeck[aCount];
deck[i] = foo;

and see which line throws the fault, which would tell you if the fault arises from reading from aDeck, or writing to deck, which potentially could help

hey, so i have an exercise in which i have to use a function to present the multiplication table of 3 numbers introduced however after that appears in the console my code asks for another number where it says "Insira um número" and i dnt want that to appear, ive tried to use a if to make it not appear but its not working and its starting to drive me crazy lol can anyone help?

[odd lily]

guys i need someone to write my programming project. do you know any websites where i can hire somebody?

[sharp vine]

has anyone used slurm to schedule jobs on linux/unix kernels?

or anyone have experience with unix in general?

[thin hound]

If you need to do Console.Write and Readline 3 times, you should try to only do it inside the loop. You can use this logic:

static void Menu()
{
  int numero;
  for(int i = 0; i < 3; i++)
  {
    // 1. Print "insert number"
    // 2. Readline()
    // 3. Print table
  }
}

There are basically n integers in the array, and each integer needs (typically) 4 bytes. So the number of bytes is logically enough, 4 times the number of entries. The solution you found is good

[quiet vault]

thank you! its kinda late but i will try it tmrw : )

[frank garnet]

macbook air m1 vs thinkpad t14 r5 both base variants

[open solstice]

what are you gonna use it for

[frank garnet]

im starting with data science ug degree

for college purposes

[idle dew]

Helooou, I am a computer science student trying to focus on making different projects for my portfolio. The only thing is that I don't want to work on them by myself so I'm looking for people who are interested in working on programming projects with me 😊 if someone is interested just message me, thaaanks : ))

[open solstice]

hmm

I think you should first look for laptop reqs in your uni/programme

if they both are fine with reqs, and if you are only going to use it for college, then both will be fine, it's just your choice

but i'd personally go with mac

because I like the design and usability, they both have pros and cons in some areas of computational sciences, but they both are like equal imo

unless you are going to use linux (but it's not a problem anymore because there's docker), because it's harder to use that stuff in m1

other than that I heard m1 chip has some problems with computer graphics area but that just what I heard so keep that in mind

they solved them all with m1x tho, so if you have money m1x one would be a better choice

[idle dew]

max or pro?

or is it no difference

for uni student

[open solstice]

I think they both are okay (max is deffo okay, but i'm not 100% sure about pro but probable it's okay)

[open solstice]

oh you are asking in general

they both will be fine

[idle dew]

bro but they are so expensive

[open solstice]

yeah lol

that's apple thing

m1 is also fine as I said

you can do all of the things with m1, but as I said ppl had some problems in the computer graphics course

[idle dew]

yea vms are the main issue

and m1 is kinda buggy, m2 should be really good though

[open solstice]

also if you are not (going to) study a computational area, m1 is perfect

[open solstice]

i personally don't use mac, so idk, but m2 should be better ofc

[open solstice]

yep, but there's docker

[idle dew]

oh really, but u said u prefer it

then why go to windows

[open solstice]

last year my school said they don't prefer m1 chips, because there was no way to use vm, so I bought my current laptop and after that docker solved the issue

[idle dew]

what laptop?

if i may ask

[open solstice]

and my school said it's ok to use m1 now

im debating that or the 13 inch pro or air next year

well 13 inch xps

[open solstice]

it's a hard choice

both specs are really good

[idle dew]

the xps displays tho

[open solstice]

and design is very good at both

yeah screen of xps is cool

I don't have 4k one because it was 200euros more and it decreases the battery life

[idle dew]

@unkempt ocean discrod is back

[idle dew]

on 13 inch there is no difference in 4k or uhd

i just dont want touch

i have ipad pro and it i sreally good

i also have intel mac but its pretty muc dead now so i need a new comp

[open solstice]

I had the same issue

[open solstice]

Touch screen is not worth it imo

So yeah

That’s the reason of the lower battery life

[idle dew]

exactly

but it looks so sleek

do u have black or white

[open solstice]

Black

[idle dew]

yep good choice

im thinking of that as well

can i ask if u prefer android or ios @open solstice

[open solstice]

ios

[open solstice]

the other one is more expensive for no reason, and I think this one looks better lol

[idle dew]

but i don't know if i am doing it correctly

[west lichen]

hey do you know what caused the display problem for me ?

i explained it above

[open solstice]

sorry 😦

[open solstice]

I think it's 7n^2+5n+2

3n+2 for the first loop

[west lichen]

ehh ok no problem

😎 👍

[open solstice]

3n^2+2n for the inner loop

[crisp cypress]

there is no such answer ;/

[open solstice]

and 4n^2 for the if statements

[open solstice]

dammnn

weird

[crisp cypress]

ye

[open solstice]

what's the exact question

[crisp cypress]

How many dominant operations this code will perform

"licz < x" is dominant operation

so there are 2 dominant operations

[west lichen]

are you using vs code studio ?

virtual code studio *

[open solstice]

ooooh dominant operations

[crisp cypress]

visual Studio Code ?

[west lichen]

ye

[open solstice]

then i'd say the answer is 4n^2+2n

but wait

no

[crisp cypress]

can u explain this?

[crisp cypress]

yes

[open solstice]

I assume dominant operations mean best case

but it's still weird

hmmm

[west lichen]

ohh ok

😎 👍

[crisp cypress]

look there are 2 dominant operations "if (licz < 500) ..." and "if (licz > 30)" and we must count how many times they will be executed depending on "n"

[open solstice]

I am confused with the term dominant operations

[open solstice]

ohhh

then it's 4n^2

[crisp cypress]

why

[open solstice]

they are inside of a loop inside of a loop

so 1 operation will take n^2 in that area

[crisp cypress]

but, the second loop have "j<i" not j<n"

[open solstice]

comparison is 1 operation, printing is 1 operation, so 2 operations for 1 if statement

[open solstice]

damn i missed that

hmm

Hi Im currently at my last year of High school and just wondering if I should take Computer Science or Computer Engineering does anyone has any experience with those courses? Im currently still confused on what course should I take

[open solstice]

It depends on what you want, computer engineering is like a substudy of electrical engineering, mixed between computer science and electrical engineering

in computer science, you are focused on the software side, while in computer engineering you also learn some hardware stuff

physics is needed for ce and it's not needed for cs

If you have acrobat you can use create PDF tool and upload the dwg file. If not try using any online converter.

You can use Plot option as well in autocad

[wheat silo]

Do you mean like this?

[wheat silo]

so it shows the formula not the value?

The color you can change it by using the table design - quick style, it will follow the color format when you dropdown or enter

[wheat silo]

I did this by select 2 rows 2 column cells - go to insert - select table, fill the number in the row 2 column 1, fill the formula in the row 2 column 2 then enter (by this next row will be automatically formatted by the color I use and the value shows), dropdown will show the same result as this

Since no value on the column 1, the values returns zeros

I hope I didn't misunderstand you

Check your bios maybe?

[versed spoke]

#include<math.h>
using namespace std;
int main ()

int i = 1, j, r;
float num;
char hex[50];
cout << " Enter a decimal number : ";
cin >> num;
long temp = num*pow(8,8);
while (temp != 0)
{
r = temp % 8;
if (r < 10)
hex[i++] = r + '0';
else
hex[i++] = r + 'A';
temp = temp / 8;
}
cout << "\nOctal equivalent of " << num << " is : ";
for (j = i; j > 0; j--)
cout<<hex[j];
return 0;
}

main problem is that I don't know how to put fraction after the first digit is shown.

[fallow sinew]

`int main()
{
int userInput;

//Loops through the recursion method until the user inputs 0
while (1)
{
    
    printf("Value: ");
    scanf("%d", &userInput);
    if (userInput < 0) //This is the line that needs help
        {
            return 0;
        }
    if (userInput == 0) 
    {
    printf("Fibonacci number %d is %d\n", userInput, fib(userInput));
    return 0;
    }
    printf("Fibonacci number %d is %d\n", userInput, fib(userInput));
}
return 0;

}`

how would i make it so that it ignores the user's input if they input a value that's less than 0 and continues through the loop prompting the user

for example the console will display: "Value: " then user inputs '-1', then it ignores that input and continues to prompt the user, "Value: " until a number <=0 is put into the console

[storm pine]

do
{
printf("Value: ");
scanf("%d", &userInput);
}while (userInput<0)

you can change it to that

[dusky igloo]

not entirely. There will be occasions that some websites require you to access through a computer only. Some tasks can be done faster on a laptop too, but there are tasks that are the other way around, i guess.

[dusky igloo]

you can do all your daily tasks on an iPad, but a laptop might do a better job at managing your resources, like files and data. But if you're subscribed to iCloud storage, that should deal with it for you.

I have seen some videos about programming and want to learn it (not like getting degree) . Can anyone tell me where to start first and recommend some yt channels or playlists regarding it. and if I learn programming what type of things can I do with that knowledge.

[abstract sequoia]

I don't recommend using yt to learn programming tbh

there are good free websites like codecademy and others

[idle dew]

I have seen some videos regarding programming in a channel called freeCodeCamp.org but couldn't decide where to start

like what should I learn first

?

[abstract sequoia]

I don't think that really matters

personally, started off with js

[idle dew]

like I will learn javascript first ok

then what will that knowledge help me to do ?

[abstract sequoia]

web dev

[idle dew]

ok and will it help me for game dev ?

ok so different game engine uses different language I get it now

thanks @drowsy dagger and @abstract sequoia for the help

[left arrow]

i would kinda disagree with that youtube is a bad learning resource, i've learned so much from it :)

sure, there's tutorial hell and stuff like that, but if usef correctly (as a side resource) it's really helpful!

good luck on your programming journey @idle dew !

unity is great if you want to learn game development. when i started out, i picked unity after month of learning python. i think unity's a good place to start out, but be careful of tutorial hell. it basically means that you can't create stuff yourself, and you can only implement stuff using tutorials or by copying other peoples code

in the beginning it's understandable and totally fine to follow along tutorials, but you should be able to do really simple programming projects after a while by yourself :)

i don't have enough knowledge of unreal to tell about that

[idle dew]

OK got it and thank you

[left arrow]

yes, but unity's c# differs a bit from "real" c#. :)

[idle dew]

ok

[left arrow]

and also, good luck on learning programming!! remember, it'll take time, enjoying the journey is sometimes the most important thing here

[idle dew]

👍

[left arrow]

also, if you have interest in doing other projects than gamedev, i would recommend that you watch this video. it basically explains what I try to say in a much better way :) https://www.youtube.com/watch?v=nBaCRp9UzDw

i'm sorry if it's not allowed to share links, i'll delete this then.

also, i'm not saying you shouldn't use unity. it's a good engine if you want to make games.

otherwise i would recommend to learn programming with a language. it's much easier to switch to a game engine from example python or c++ than vice versa :)

Anyone good with Java?? I need to find a way to get how long in hours minutes and seconds (hh:mm:ss) have passed between to dates

I need to store the dates as some type of object that keeps the date and time

[open solstice]

it's not that important, the algorithm is good if when you divide from the pivot point number of elements in the left and right sides are close, but we can't select the best pivot without searching for all, and we can't do that because it won't be efficient

so there is nothing to do about it

but in the time complexity sense it is important because time complexity will be different with a good pivot and a bad pivot

but there's nothing to do to choose the best pivot

[open solstice]

I don't really understand your question

but from what I understand you have to create a class called date or something which has the properties of a date

[open solstice]

btw best case is O(nlog(n)) and worst case is O(n^2)

Are they properties of an object?

Or are you gonna store them in pairs

hi

how can i center my card in bootstrap 5

[open solstice]

As I said you can use split method to take the hour minute second, in this case the split operator should be “:”, the example use would be, if you store the date in a String s,

String[] arr = s.split(“:”);

Therefore hour is at index 0, minute is at index 1 and second is at index 2, but they are in string foem so when you want to do mathematical operations, you have to use ParseInt or Integer.valueOf

For the math part you can change everything to seconds and do the subtraction

Then by using % and / operator check how many minutes and hours and minutes and seconds are there

For example if there are 65 seconds, if you use / operator with 60, you get 65/60 which is 1, which will give you the minute part, and when you use % with 60, you get 65%60 and this will give you 5, which is the second part, so you get 1 minute and 5 seconds

[scarlet ferry]

What problem u got?

[azure timber]

#given length of survey list,states in country,month,survey rating list

return country number and survey rating of state at given month.(1 state takes 1 month to survey)

#output: country number and state rating

conditons:
#start with country with lowest rating
#finish one country first

example
length_survey_list=9

states in country=3

month number=6

survey_list=[1,2,1,2,3,4,5,2,1]

output:
country -> 3
state rating->5

explanation:
country 1 -> [1,1,2] (sorted to pick state with lowest rating if same then check next index)

country 2 ->[2,3,4]

country 3-> [1,2,5]

first country 1 is picked because second rating is smaller than country 3

therefore first country one is traversed then we move to country 3
on sixth month we are on 3 country and state with rating 5
this is our output.

hint or psedocode would be helpful thanks

#[[1,2,4][1,1,3][2,4,5]]
group=input1//input2
ll=[]
for i in range(0,input1,group):
input4[i:i+group]=sorted(input4[i:i+group])
ll.append(sorted(input4[i:i+group]))
print(ll)
print(input4)
print(min(ll))
print(ll.index(min(ll)))

while input3>1:
    idx=ll.index(min(ll))
    for i in range(input2):
        if input3==1:
            print(idx,ll[idx][i])
            break
        else:
         ll[idx][i]=999
         input3-=1

main()

some print statements are redundant but helps in understanding what i did

[thin hound]

If I understand your question correctly, it's pretty much just

def and_gate(a, b):
  return bool(a and b)
def or_gate(a, b):
  return bool(a or b)
def xor_gate(a, b):
  return a is not b

I would recommend having the inputs be boolean types (alternatively you could use the integers 0 and 1 instead in which case you might want to convert the output to int as well, by using int()).

[thin hound]

You might not be linking the math library https://stackoverflow.com/questions/12824134/undefined-reference-to-pow-in-c-despite-including-math-h

[thick sedge]

Yes thats exactly what I was thinking of, thank you!!
Do you happen to how to make truth tables as well?

[thin hound]

That would be a bit more involved
You should then make a function that takes a list of gate-functions as argument, and then makes a truth table for each:

def truthtable(list_of_functions):
  print("Func. name | 0,0   | 0,1   | 1,0   | 1,1")
  for fn in list_of_functions:
    print('{0: <10}'.format(fn.__name__) + f" | {fn(0,0)} | {fn(0,1)} | {fn(1,0)} | {fn(1,1)}")

so you'd do

truthtable([and_gate, or_gate, xor_gate])

[thick sedge]

I see! Thank youuu ^^ much appreciated

[potent scroll]

for element in list3_1:
    list3_2.append("Dr." + element )

@random spoke for each element in list1, "Dr." we add it and add it to list2

[potent scroll]

my_list = [("Dr."+ element) for element  in list3_1]```
or you can use list comprehension and you can do it in one line

One-to-Many: when a row on one table is related to one or more rows in another table.
A primary key column value from one table’s row is referenced by one or more rows in another table.

for example:

from this relationship:

• One pet owner can have many pets
• While a pet can only have one owner (just for example purposes)

One-to-One: when one row on one table is directly related to a single row in another table.
The primary key may be the same on both tables.

for example:

Many-to-Many: when a row in one table can be associated with one or more rows in another table and vice-versa.

for example we will be using the same pet and owner tables but add a new rule: A pet can now have more than one owner

we don't want to add columns to the pet table for each owner.
We see a NULL whenever a pet does not have an owner. The more owner columns, the more NULLs.

hey guys quick question

so this is my code

  public static void Main() {
    int n = 5;
    var s = "";
    for (int i = n; i <= n && i > 0; i--) {  
      for(int j = n; j <= n && j > 0; j--) {  
      s += j;
      }

    s += "\n";
    }
  }
}```
and i want s to be``` "54321\n4321\n321\n21\n1\n"```
but now its ```
"54321\n54321\n54321\n54321\n54321\n"```
does anyone know how to fix this? this is in c# btw

[strange zodiac]

on your nested for loop it should be for(int j = i; j <= i && j > 0; j--)

[idle dew]

ahhhh thank you sooo muchh

[strange zodiac]

tbh you dont need that int n = 5

but ig its good that you have it there so you only have to change the value once then 2 times in your for loop

[idle dew]

Ahh yea well im new to coding and this is my first time coding with c# so im really just doing whatever honestly but thanks alot man

[strange zodiac]

no problem

[idle dew]

you really helped me out 🙂

[strange zodiac]

id act say keep the int n = 5;

in the future you might want to see 6 instead of 5 - possibly 10, 20

you can easily do that by changing the n value instead of replacing the n in your for loop with 6

[idle dew]

hmm yea ur right its easier to change now

[strange zodiac]

the way I was taught was that you have to create a third table (JOINER TABLE) that will reference the PK on both sides

2 options on the kind of table you want: you can choose whatever works best in your ERD

should have done this on a thread but hope it helps

The best way to start learning any language or framework is learn from their origin website. You can find any docs you want in those websites
https://www.javascript.com/

[scenic oriole]

or yt lol, it can be more beginner friendly

people who are new to programming have trouble sometimes navigating through documentation sometimes, but youtube videos always have really good explanations esp the introduction ones

I'm Planning to Deploy my Node Js Back-end and MongoDb Database, I also need File Storage system to handle file upload, based on the above conditions, whichs AWS products should I use?

[lime rain]

Checkout "Simplify" for the backend, it will help you if you need a kind of CD, if you just want something not that serious I would use EC2 machine and install node on it.
About mongo, search for "document-db" that's mongo.
I hadn't messed with file storgae but I think "S3" is the product you're searching

[outer coral]

oh ok, for production level, how much money do I need to Prepare ?

money*

[lime rain]

EC2 is just a machine aws is providing to you and you can connect to it using ssh and do what you want

[lime rain]

Ahm, it's hard to estimate due to the fact that I don't know your needs, you can check the docs for pricing.
But overall I was surprised with the prices when I checked

What do you consider as "production"

If you think you will need multiple instances I would checkout kuberenets on top of AWS, but I didn't get a chance to mess with that

[outer coral]

I'm Currently Planning on an E-commerce for a University level National Competition at my country,

[lime rain]

Allot of users and traffic?

[lime rain]

It's one lf those terms that people misuse allot, for your use case it will be enough to say that when the document is loaded by the browser internally it's represented as DOM which is a tree where each element in the HTML page is represented as a "node". A node can have inner nodes (e.g 'div' inside 'div')

If you're interested in the more abstract term you can read https://www.w3.org/TR/REC-DOM-Level-1/introduction.html

[outer coral]

prob less than 1000

users/day

but if its actually win the competition expecting those Traffic to be higher

[outer coral]

cause it will be funded and used by the government

[lime rain]

I would have gone with a kubernetes solution in that scale, so you will be able to scale up your application easily

[outer coral]

ok thanks, really appreciate your help

[lime rain]

Sure 🙂

[idle dew]

TYSM!!!!

[thin hound]

I'm not familiar with all the terminology of the question, but wouldn't it just beP(W="table") = P(Y=[class containing the word "table"]) * P(C_1 = "t" | Y = [class conta...]) * P(C_2 = "a" | Y = [...]) * ... * P(C_5 = "e" | Y = [...])

[idle dew]

To understand what is DOM, you need to know why is DOM
DOM reference for Document -> Object -> Model. But why is DOM? Why isn't OMD or MOD
Look at the picture, you can see the root is Document. Why is Document in the root? If you watch closly in each html file, you will find the <!DOCTYPE> in first html code. But why we need the <!DOCTYPE> in html file? To define the website that you can run smoothie in every version of each website (Chrome, Firefox, IE)
Second is object. Why is object? Every function in JS need an object to return a value. Example to run function runMusic(), you need to create an object called var musicPlaylist = [ { id = 1, name: '||Never gonna give you up||' } ] then map it in the function to run it
The last one is model. Why is model? Now you have a run music function, but how can you put it in website for user to use it? Make a button. function runMusic() { return ( <button type='submit' onClick=''>Play music</button> ) }
That's how i understand about DOM in html. If you're still confuse it, i'll explain shortly
|| Define website -> Create back-end -> Create front-end ||

[pastel kraken]

the DOM sounds complecated but its simple...simpler than trying to understand the monstrosity called js

reactjs is good js library for web development too, but if you want to master js and reactjs. you need to forget everything about OOP and focus on Function Prgramming

because it's retarded

it's a god tier language but it's so bad to implement

Hey if you do have a basic idea of machine learning and/or NLP sentiment analysis would not be too much of an issue .
If you're looking for something more basic you could simply just implement an ANN from scratch or check out CNNs for image recognition tasks.

What's the ideal cpu temperature for any laptop?
Ig my laptop has heating issues...whenever I watch lectures on it the temperature of my cpu goes to around 80°C....is it normal? If not please suggest me some ways to prevent it.

[red hare]

Try opening it up and cleaning the vents

Probably they are dusty

use compressed air and hold the vents while you do it so they dont rotate backwards, it could damage them

you can also apply thermal paste of the cpu

helps dissipate the heat

I don't really understand your question

[thin hound]

It has to do with how you are calling show(). You need to consider the call-graph of your function. Only after your function is recursing (ie. after you have called s() for the last time), should you call show(). That means you can remove your call to show() in s(), and add a helper function s_helper(), which calls s() once, and then calls show(). The helper function would look like this:

def helper_s(A, B, C, n):
  s(A, B, C, n)
  dessin.show()

First Normal Form (1NF):
  consider:
    - all attributes contain an atomic piece of information
      > complex attributes need to be broken into their own separate columns
    - there exists a primary key [PK]
    - There are no repeating groups
      > columns containing sets of values will need to be move into their own table(s)

from the CD table you have there you would focus on the 2 and 3 point

• there is no complex attributes
• you can set a PK
• there will be repeating groups so you will need to move that whole section on its own

you will have two tables (CD and TRACKS)

on your tracks table it will need to have its own PK so it would either be a composite or surrogate Key

its a good way to start lmk when you finish 1NF

[amber mountain]

can you illustrate it?

just like in the picture?

[strange zodiac]

the table is all you need honestly - idk how to illustrate that without giving the answer away

from what i have said

what is the PK of CD
