What should i do now

[unborn talon]

ahh, going to do some guessing here but standard cmos features

um did you check your computer supports UEFI booting?

[fluid jewel]

No. Its legacy but i want to convert UEFI firmware for Virtual Setup

[unborn talon]

virtual setup?

[fluid jewel]

Yeah. I want to learn Android Programming but my pc didnt support VT so i have to setup in bios

[unborn talon]

what pc is it?

[fluid jewel]

Dell

[unborn talon]

what specific model

[fluid jewel]

Legacy

[unborn talon]

no like is it a dell latitude 2210 or a dell optiplex 790 or something

[fluid jewel]

I only know that come from 1984-2008 award software. Hardly to remember which is dell latitude or optiplex

[dusk cape]

hey

[fluid jewel]

But there anything i can do to fix my pc bro

[unborn talon]

Dig around bios for a setting that lets you boot uefi instead of legacy. There’s a chance your bios doesn’t support uefi though…

[fluid jewel]

Its still legacy. Im tried to convert but failed like first pic and now my pc cant start windows

[unborn talon]

Yeah it didn’t fail to convert. It succeeded

[fluid jewel]

Well but i cant find anything similiar with uefi setting. So hopeless

My keyboard stil not working tho

[unborn talon]

yeah i dont know sorry

[fluid jewel]

Its ok, thanks for your jelp tho

[rich canyon]

Do you have another computer?

Maybe you can connect your hard drive to the other computer copy your data

And install a fresh windows

@fluid jewel

[fluid jewel]

No. I only have 2 laptop but all of them are Mac

[rich canyon]

You can read NTFS formatted disk in Macos

[unborn talon]

you might need a sata to usb or something of the sort

[fluid jewel]

How do i do that bro

[fluid jewel]

Neither of them i have tho

[rich canyon]

https://www.howtogeek.com/236055/how-to-write-to-ntfs-drives-on-a-mac/

I think but I don't own a mac

https://discussions.apple.com/thread/251337359

[fluid jewel]

Ok ill read it. Tks for your help

[rich canyon]

Your welcome

I hope you can fix it.

Or do you have an empty disk?

Then you can also do a fresh install on that one

Copy the data over

And move back to your primary disk

[unborn talon]

Oh. If you have a usb you could boot windows 10 installer potentially and convert it back to legacy maybe?

[inner tiger]

Hi can anyone explain how this is D, I tried tracing the code and got 256

[wooden kindle]

It's a recursion problem

[wheat swallow]

4* 3 * 2 *1 *1 its the factorial function of n

[wooden kindle]

And the function has the logic for factorial calculation

[wooden kindle]

Yea exactly

[inner tiger]

got it! thanks!, yeah I should've taken a closer look and realized it was a factorial function formula

[worn moth]

anyone else use anki with cs?

[worn moth]

a good way to visualize these is writing down the statements and what there output should be in like a chart if you cant solve it in your head

like:
rose(4) = rose(3) * 4
rose(3) = rose(2) * 3
rose (2) = rose(1) * 2
rose(1) = 1 * 1

then going back up and filling in the numbers:

rose(2) = 1 * 2 = 2
rose(3) = 2 * 3 = 6
rose(4) = 6 * 4 = 24

24 final answer

[dusk cape]

I am not able to connect nodeJS to MySQL database (workbench) if anyone know how to connect please help me.

[unborn talon]

what os

[lunar nymph]

Windows

[unborn talon]

i might be wrong, but isn't mysql workbench just a client, and not the mysql server. so maybe the mysql server isn't running?

[lunar nymph]

created a local host

[versed condor]

Hello. I have a question regarding creating an environment in gym, Python. Is it absolutely necessary for the action_space and observation_space to be the minimum size?

[wooden kindle]

I'm trying to check for a state value within a setInterval , but the if check isn't doing anything.

[spare ocean]

whats your code?

[wooden kindle]

How do I send it. Just paste it here?

[spare ocean]

yep

[wooden kindle]

const handleStartStop = () => {
    if (intervalId) {
      clearInterval(intervalId);
      setIntervalId(null);
    } else {
      const sessionInterval = setInterval(() => {
        if (sessionLen > 0) {
          setSessionLen((prevSesLen) => prevSesLen - 1);
        } else {
          console.log(sessionNo);
          console.log(sessionType);
          if (sessionNo < 4) {
            if (sessionType === "Focus") {
              setSessionType("Short-Break");
              setSessionLen(() => shortBreakTime * 60);
            } else if (sessionType === "Short-Break") {
              setSessionType("Focus");
              setSessionLen(() => focusTime * 60);
            }
          } else if (sessionNo === 4) {
            setSessionType("Long-Break");
            setSessionLen(() => longBreakTime * 60);
          } else {
            clearInterval(sessionInterval);
          }
        }
      }, 100);
      setIntervalId(sessionInterval);
    }
  };

@spare ocean

[unborn talon]

oh, i think you might have a problem where setinterval doesn't get an up to date copy of state

[wooden kindle]

yeah

what do you think is causing it?

[unborn talon]

dan abramov writes about it

https://overreacted.io/making-setinterval-declarative-with-react-hooks/#just-show-me-the-code

[spare ocean]

if I'm not mistaken, clearInterval takes the interval ID, try assigning the interval to a variable or problem not here?

[wooden kindle]

yeah the problem is still here. im reading the article. The problem is with state within the setInterval. clearInterval is working fine.

[pure zealot]

Hey guys any experienced editors

I need help

Ill dm u

if thats not important ill check it in editor soon

[wooden kindle]

thank you.

Hey guys

Anyone

[unborn talon]

ive got it working in a code sandbox, my logic around changing between sessions is wildly wrong though

[wooden kindle]

can i see it?

[unborn talon]

ill dm you a link, its pretty thrown together 😂

[idle dew]

Hey guys i was thinking about buying myself a tablet in order to getting more organized in my studys. Annyone can recommand me anny devices? I was thinking about getting a Samsung galaxy tab s6 Lite with 64GB . It costs 269Euros which sounds affordable for me . I know IPads are very reccomended by a lot of students but i need to keep it Budget friendly 😛

thoughts?

[spare ocean]

can i get all setState hooks pls

[wooden kindle]

https://github.com/AnilSeervi/react-projects@spare ocean

[spare ocean]

so your expected output: 1, 'focus'?

[wooden kindle]

@spare ocean yeah when sessionLen become zero I want it to enter the if check
But it doesn't

[idle dew]

Building a pc is easy but making it fucking work is hard for some reason

[spare ocean]

As I understood in the interval, you will not remember the state in any way, this should be done in the useEffect hook, and the function itself clears \ starts the interval via handleStartStop

[wooden kindle]

Oh I see so that's why it wasn't holding the state.

[unborn talon]

What’s wrong?

[idle dew]

who knows about packet tracer?

[sudden trout]

anyone wanna do a group of programers where everyone can work together and create a program?

[hallow mist]

sounds like a hackathon

[sudden trout]

yeah but more virtual

[unborn talon]

like create a pomodoro timer?

[sudden trout]

and not like a one time thing something like you do as a programming group

[sudden trout]

lol

[unborn talon]

its what 乇urus is doing

[idle dew]

Yes sure , it depends the most on myself . the only thing is , so far i always worked with paper and pen . But since i entered medical school , i cant work with the same efficiency as in High school so i thought about changing my way of taking notes and to compress all the stuff i write down on one tablet .

[idle dew]

Oh my bad I thought you were a middle school-er

Well with my experience, I would suggest you buy an iPad for the following reasons

Reliability
Good cross platform along with a mac
No crashes
Good apps such as goodnotes
apple pencil support

Are you from India?

And more easy to use back up system

don't want your work to get deleted due to a technical issue

@idle dew I beieve you on this one 🙂 IPads are very simple to use and work really great , the only problem is the price and i never used apple products before so compatibility would be a problem. I ordered the samsung galxy tab s6 lite now and i hope it will do fine

and Also an iPad lasts longer than your average android phone

[idle dew]

I only have an Air 4 and it's fine

You can also get student discounts too

[idle dew]

No i always save my work on a cloud this wont happen. I live in germany btw

if you buy from apple official store

The thing is my android tab glitches and crashes so frequently it was so frustrating @idle dew

Have you seen the basic iPad model?

Also apple care is such a peace of mind

I broke my screen and they fixed it without drama

has anyone here worked on Yara?

[gleaming dragon]

Im having an issue at the moment with an easy code, it says it can't find a symbol in my code but it told me to write the EXACT thing it wrote..

[gleaming dragon]

So when you are coding, are you expected to know some strings or something like that???

Because I been looking at the same code for a few minutes now and I honestly have no clue what I am suppose to do!

[strange zodiac]

can you share your code?

[gleaming dragon]

Codewars

8kyu
Multiplication table for numbers

This is what I am looking at

[rich forge]

what is the error?

[gleaming dragon]

Me ....

I don't know what I am doing

Test it to see what it was but this is what I get

I'm trying to understand this but no matter how hard I look or where I look I just don't understand it. For example

class Kata {
public static String multiTable(int num) {
return ""; // good luck
}
}

I start with that, it doesnt tell me if I have to add to it, if there is something I have to use from that, then I have some "sample tests" below it and its even more complicated and is so frustating that I am trying my best to keep my cool.

[strange zodiac]

you will be adding code to that function to get the results located on the left

how you do it to get the results is up to you

the sample is just an example of what you can do with the function

[gleaming dragon]

So for me to do something with the results I need to add something cool, what exactly do I need to add not quite sure, do I need some special code in order to get the results? Is the answer literally on my face and I am to blind to see it?

[strange zodiac]

you have to figure that out since its a coding challenge if i am correct

so you have to think things through creating variables, doing some math to get the results

[gleaming dragon]

doing math is not hard for me, but no one has explained, teached or at least display how to create a variable... I am new to coding, and it feels like I needed some sort special training just so I can get start on a code that for anybody else seems like it was very easy

[strange zodiac]

ahh

its Java right?

[gleaming dragon]

Right

[rich forge]

there are a lot of great sites/videos to start learning how to do all those things.

[strange zodiac]

for the basic syntax

{variable type} {name of the variable} = {value};

for example you want to create an integer

int number = 1;

for types of variables https://www.w3schools.com/java/java_variables.asp

or other websites

but i would look at videos first before diving into coding challenges

[gleaming dragon]

Videos on youtube or codewars?

[rich forge]

I have never used codewars, i usualy look on youtube

[strange zodiac]

codeacademy, udemy, etc.

freecodecamp as well

[gleaming dragon]

Alright

[strange zodiac]

yeah since you are still new. you need to at least get the core fundamentals down. I have never used codewars and it looks like you are using the knowledge you already have to solve challenges and what not

[fair fossil]

How was this resolved (it's asked to find Norton equivalent)

[unborn talon]

does anyone want to form some coding challenge group? (leetcode, hackerrank etc)

[steady forge]

anyone studying electrical and electronics?

we can make a seperate channel or ask the admin to make a separate section for us

someone tried adding a channel before they dont want to but try your luck

[ashen wharf]

yo guys if i have a function in python that return a boolean and a set, is it possible to use only the set output?

returns*

[upbeat mountain]

is the boolean in the set?

[ashen wharf]

no, for a bit of context it returns a boolean and then a set

'return False and Population_set'

btw i changed the 'and' with a ','

[upbeat mountain]

an du want it to only return the set output

?

[ashen wharf]

Not really, i need both the boolean and the set

but in different cases

[jade sandal]

you can say a, b = func()

and b will be the set

and a will be the boolean

if you return as a tuple

[ashen wharf]

that should work!

Thanks!

i use leetcode and hackerearth .. codeforces sometimes

[unborn talon]

ive just started working through Top Interview Questions on leetcode

which is mostly me looking at the question and going lolwut

[polar flint]

you become better by starting that way 🙂

lets have a 100 days of code challenge.. maybe 5 leetcode questions per day.. 2 easy 2 medium 1 hard or 3 easy 2 medium

[unborn talon]

the monthly challenges?

[polar flint]

the leetcode monthly challenge? thats fine too

[unborn talon]

oh, i misread you sorry; i thought you were saying leet code had an 100 days of code challenge 😂

[unborn talon]

yeah lets do this!

[polar flint]

how do we go about it?? make a new group??

[unborn talon]

i was hoping we could get a "coding" channel created but ive just read someone wanted an electrical one and couldnt get it

[buoyant dew]

anyone knows the best way to populate databases? I was thinking about using a python script

[upbeat mountain]

sql?

[unborn talon]

what format is the data in?

[buoyant dew]

mysql

something like this

but like at least 1k lines of data

[unborn talon]

If you’re dealing with tabular data, read it in from a csv in python and execute sql

[buoyant dew]

testing a webapp

im not, I would need to make it random

i dont have the data yet

[unborn talon]

Oh if you’re generating random data then yeah. Python random vars into sql

https://www.w3schools.com/python/python_mysql_insert.asp like this

Unless you’re using an ORM then just use that lol

[mystic crater]

btw you can just do

INSERT INTO table
(col1, col2, col3)
VALUES
(X, Y, Z),
(A, B, C),
(D, E, F);

[onyx rose]

im stufying this tomorrow if i get it ill help you

[buoyant dew]

I mean its not super random, because I need to match users ID to their name and not insert duplicate date

im making it a script that writes to a txt doc i guess

[onyx rose]

Make sure u learn thevinin before and after u just got to use the converstion.

[buoyant dew]

my idea was to do something like a class User

class User:
  def __init__(self, id, username, mail, passwd, location, firstName, lastName, country, birthDay, address, phoneNum, type)
  ...

but i need to populate that class before writing it to the txt file

[fair fossil]

@onyx rose Ok but it's very difficult, don't sweat it, you might not get it as well, I'm going to skip the excercise for now

[pearl cedar]

Not sure if this is helpful, but if you're writing a class anyways, maybe using SQLAlchemy's declarative base will be helpful (I think this is what xanderle meant by an ORM). https://docs.sqlalchemy.org/en/13/orm/extensions/declarative/basic_use.html. Basically something like this:

Base = declarative_base()
class User(Base):
  __tablename__ = 'user'
  id = Column(Integer, primary_key=True)
  .... # define all columns

# insert using session:
engine = create_engine('<mysqlenginstring>')
Session = sessionmaker(engine)
session = Session()
session.add(User(id, username, ...)) # insert a new row
session.commit()

I have interest in coding so going to learn python anyone have tips for me?

[regal quartz]

It's good to have some idea of what you're actually gonna use it for

A lot of people do these "learn to code" type things but don't end up really remembering or understanding it because they don't get to apply it to anything

[idle dew]

Start small, watch videos covering the basics. Go to websites which have practice problems. Practice, practice and practice. Eventually, you'll start to do projects and it'll expand your knowledge as you go along.

[lofty folio]

I've also tried getting to learn Python, but sometimes it can be so hard to setup my IDE.

any programmers with data structs and algos experience in here ? i got a tough assignment and i wanted advice

[unborn talon]

probably be easier to just ask

[gleaming trail]

i need to make a simulator that captures the spread of covid through a given population size. We are given 3 different files of 2 million Persons. Each person visits other ppl periodically every 1-7 days.

the population starts with a given number of ppl that have covid 1-10

my question is, what data structure should i use ?

i was thinking hash table or btree

but splay also seems logical

any insight ?

ping me if anyone thinks of something

[peak viper]

Does anyone draw with Siemens NX 12 often and can help me with a problem?

[unborn talon]

to me it seems like a graph problem but ¯_(ツ)_/¯

[gleaming trail]

youre right bro we gotta find the shortest path for each person that interacts with each other. im just wondering what structure i should pair it with cause i need to store the 2 million Persons

but for sure graphs thanks 💯

[unborn talon]

whats your worry about the 2 million? processing time?

ahh, so when you say a hash table you're thinking you can instantly look up a person and see if they're infected or not?

[gleaming trail]

yes my bad i forgot to explain, we have to beat my professors runtime 💀

so i need a structure with a crazy good time complexity

[unborn talon]

hows the data presented?

is it a 2d array or are you given a graph + how do you determine if someone is infected or not

[gleaming trail]

we're given a file with
First line format: <population>,<number of starting people>, <first starter ID>, <second starter ID> …

All succeeding lines have the format:
<Person ID#>, <# people visited>,<first person visited ID#>,<frequency of visits to first person>,<second person
visited ID#>,<frequency of visits to second person> …

so its essentially an array to begin with

we are given the ids of the ppl infected

but theres also a catch

you cant give someone else the virus for the first 3 days you have it

[unborn talon]

what language are you doing it in?

[gleaming trail]

CPP

oh shoot one more thing

[unborn talon]

and is frequency of visits an int or an array?

[gleaming trail]

no STL

frequency is int but

but it could be organized into array

[unborn talon]

like how do you tell if someone visits someone else in an iteration

[gleaming trail]

we're given <frequency of visits to x person> and frequency is randomly set to 1-7

[unborn talon]

b-tree and a queue for the sound of it then

[gleaming trail]

so every 1-7 days it will iterate

[gleaming trail]

oh YOO my partner and i were considering btrees

thanks man that sounds solid

and a queue to set frequencies back in order i see

genius dude ty

[unborn talon]

ah, like the queue stores infected ids, so you can just pop them off and add them to a different queue for the next iteration

[gleaming trail]

ohhh i see so the btree would just hold all the Person objects right

and chances are the same leaf node accessed holds the person being met

improving the number of cache hits right ?

which would overall make the program much more efficient

[unborn talon]

i was thinking a b-tree because of the access time? you could also do an avl tree

imo do it with whatever tree, benchmark it, swap the tree for a splay tree. benchmark it

you should just be sneaky and multi thread it

[gleaming trail]

bro youre so knowledgeable and helpful honestly thanks so much, just curious, howd you learn?

[unborn talon]

wat. the b-tree and splay tree were your ideas. my only addition was using a queue to track infected

[idle dew]

Glad to help

[gleaming trail]

Hi , I'm new to coding in general, one of our first assignments was to build a payroll program. However, I can't seem to figure out what I'm doing wrong, and for example, if I input (50,20,n) I get 1100.00 instead of 902.00. Any help would be appreciated!

STANDARD_WORK_WEEK = 40
TAX_RATE = 18
OVERTIME_FACTOR = 1.5

all_data = True

hours_worked = float(input("How many hours worked?"))
hourly_wage = float(input("Hourly wage?"))
tax_status = input("Exempt from taxes?")

if hours_worked <= 40:
    normal_pay = hours_worked * hourly_wage
    ot_pay = 0
elif hours_worked > 40:
    normal_pay = 40 * hourly_wage
    ot_pay = (hours_worked - 40) * hourly_wage * OVERTIME_FACTOR

else: all_data = True

gross_earnings = normal_pay + ot_pay

if (tax_status == 'y' or 'Y'):
    TAX_RATE = 0
else:
    TAX_RATE = 18 

net_earnings = gross_earnings - (TAX_RATE / 100) * gross_earnings

print("Net wage is " + "$ " + "{0:.2f}".format(float(net_earnings)))```

ah had a hunch that it was

[versed imp]

Um i'd definitely do some print statements towards the end, print your gross earning and your net earning @normal ether

oh i figured it out, you dont have a proper boolean condition in your if statement for your tax_status

the reason why the if statement is seen as true here is because your boolean condition is "or 'Y' "

In Python, characters can be converted to their ascii values, and in the concepts of falsy and truesy values for python, 0 is seen as false and any number that is not 0 is seen as true

therefore 'Y' is seen as an ascii value that is something NOT 0, and makes your if statement true

something like this should help @normal ether

[normal ether]

thank you so much dude i really appreciate it

[versed imp]

yea np 😊

How I can make 2 computers exchange data/connect if they arent using wifi but they can be really close range?

[grim vale]

like a network storage?

or are the computers offline & not connecting to a network at all

[grim vale]

also to jump on this point, @normal ether I would highly recommend having print statement in every single conditional expression, it helps track what is working & what isn't during testing, you can see how far your program runs before facing problems, or just to check if the conditional is working

even something as simple as print("Gets to checkpoint 1", print("Gets to checkpoint 2") etc

nothing fancy, just any sort of indication the conditional works

[young stump]

Hi I'm new to python, our teacher is asking us to make a for loop, that would print the sum of an array of numbers and also output a string with an equation with the numbers in the range. So for example, the input/output should look like this Starting number?:10 Ending number?:20 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 165

All I really have so far is ```py
starting_number = int(input("Starting number?"))
ending_number = int(input("Ending number?"))

for x in range(starting_number, ending_number):
print(x+x)

Also, we aren't allowed to use functions like sum or .join or any string manipulation, only basic iteration

[versed imp]

Hi! So you could have a variable called sum, and as you print the numbers out, you keep track of the sum being added up. At the end, you'll print all your numbers out with a '+' operator and then you can print a statement for the final value of the variable sum. Hope that helps!

[young stump]

Thank you so much man I really appreciate it that really helps

Is someone here who work with matlab?

[versed imp]

In order to exchange data, you need a medium. If they are close by, the medium or the method you would use is Bluetooth or NFC depending on what you wanted to communicate given that the 2 computers have bluetooth modules. If they're far away, chances are you will have to use some form of a network whether its wifi or ethernet.

Hi, I have a question for coding a class-based Tetris game in Python (using the turtle, time, and random libraries). Is there a way to pass a list of lists that I initialize in a class for a tetrimino tile to a method within my playing board class? I want to add multiple list of lists (for each tetrimino tile) to a list within the add_tetrimino method, so that I can randomly make a choice of what tetrimino I will add to a grid that I drew on a turtle window.

windows manager

[wooden heart]

i dont have windows on my pc

[wooden heart]

oh sorry my bad

i refer to it as desktop environment

i run XFCE

[bitter tiger]

Yeah, they're a little bit different

I run i3, it's a tiling wm so i can increase my productivity

[bitter tiger]

As far as i know, James use this on his laptop too

Maybe it is just the matter of taste, I don't like the way you have to configure bspwm, with awesome it's just a lua script and I already familiar with this language

[small python]

uname -r is more efficient to guess what os he was running

sorry for the delay hahaha

[small python]

also when you are using a tiling window manager like wm you aren't using any DE

because of this

[bitter tiger]

the whole point of that was checking os (uname -o) and not kernel version (uname -r) lol

[bitter tiger]

Wait, that diagram is cool but I'm not sure that it'sright. You still need and X Server with i3, right?
I found this link, and it seems pretty straightforward https://www.reddit.com/r/archlinux/comments/77qkbm/does_i3_require_xorg/

[unborn talon]

you dont get a full desktop env, you just get something light ontop of x

[small python]

Yeah I got it, but in some cases you can guess the distro by the kernel 'cause some distros use custom kernels, and the os of every single distro always have been GNU/Linux

[small python]

I3 is a wm right ? So it is necessary to use a display server, I guess i3 always use X but there could another wm that use other display servers for example Wayland

[small python]

That's right, is what you get when you install BSD by default

[unborn talon]

just to clarify, a desktop env is everything from system menus to task bars to a file explorer. (gnome/kde)
a window manager, manages windows. it puts the windows decorations on and lets you move them around (awesomewm/openbox)
a tiling manager, manages windows as tiles... go figure (i3/bspwm)

[small python]

That's right

Yo I've been confused on one part of this pretty easy assignment for python, the goal is to create a program that calculates the sum of a range of numbers, and then output a string with an equation with the numbers in the range. And u can't use the sum function or .join or any string manipulation. So like this Starting number?:10 Ending number?:20 10 + 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 + 20 = 165
Whenever anyone has time some help would be appreciated 🙏

[pearl cedar]

Here is one way to do this:
You can initialize a variable as the starting number ( i = 10). You need to initialize one variable to keep track of the total ( total = 0) and one variable to keep track of the string you're going to print at the end (message = '').

Then implement the rest using a while loop. Within the while loop, have one line of code which adds to the total, and one line of code which adds to the string, and finally, one line of code which adds to i

I don't use java a lot
But seems to me that this syntax ('0' || '1' ||...) will not work, java does not recognize that you are trying to compare a character with each of these characters.

You may be able to do compare equality like this:
if (input.charAt(i)=='0') || (input.charAt(i)=='1') || ....
Alternatively, I suggest checking whether your input character is within a character array.

[thorny rock]

the bigger the m the more accurate you go

although it would be hard to get infinity on a computer lol

you just make for loop and iterate over this until you are satisfied with the answer, simple numerical method of summing previous chunks to the next one

@unborn ferry

n=1;
m = 1000;
PI=0;
for n=0:m
    PI=PI+4*(((-1)^n)/(2*n+1));
end

something like this

you can always plot it to grasp it so you add a vector of zeros and you add the current value of pi to the next element

and ofc don't forget matlab arrays start from 1

so there might be a little error in my code, I have uninstalled this app

every control theory and other theoretical bullshit is so rarely used you'll forget it, except the PLC's, softstarters, inverters, Eplan, spider, and PID

[thorny rock]

and I am talking about automation / control engineer job, it closely resembles electrical engineering job and basically when you will land a job you learn everything from the beginning

plus most of the time you'll begin with low-paid job because you need to learn how to make all of those control cabinets

IF you'll land a job of course

about AI / ML... I didn't try to get a job in this field but you need to know how to operate on big data and it is really close to data scientist from what I have heard so you need to know how data analyst works, so basically you might start with spreadsheets and excel lol

other field you can try is making embedded systems if you're fluent with C

[tacit kite]

Not sure excel will get you far. R is a good start in data analysis, even though many have shifted to python, for instance

[dusky stone]

If you are deeply interested in mechatronics then i suggest go on and do some courses on those. One i would suggest is autonomous mobile robots by eth zurich on edX. Other than that you'll find a lot of theoretical knowledge on some coursera courses.
Try learning some softwares like ROS which helps a lot in these fields. Have a combined knowledge of coding, electronics and mechanical stuff. It helps a lot in such courses. Have a deep knowledge in linear algebra. If you are solely interested in the coding part then start learning machine learning and interact on bigdata. Rest assured you'll do good on what the professors are teaching and how much efforts you out in them.
Even ill be doing my post grad in the same field soon, so i have fresh knowledge on the same. Feel free to contact me if you need any help. cheers mate 🙂

does anyone have a good way to make large decision tables, I need a table 2^11

This will take forever by hand and is going to hid mistakes

I tried to look up a generator but they all seem alittle cluncky

[jolly crow]

hello! i have a question regarding python language. so i have been going through my exercises for my final and i was wondering is counter the number of times the loop will be doing?

for example I had one of them this way:

and the other :

the counter time changes so it refers to how many times I want the loop to go?

[verbal wraith]

In this case, not exactly

Here it seems like you are establishing a constraint on the counter which allows the loop to terminate eventually

Which is "counter<10"

How many times the loop runs depends on the initial value of the counter variable

[jolly crow]

ohhh yes so the variable put in this case is to stop the loop at a certain point?

[verbal wraith]

Yes

There are many ways to write a loop

[jolly crow]

thank you so much!!

I want to run C++ code in Ubuntu which has SFML graphics library
how do i get to run or add the paths? i am lost

any help?

[verbal wraith]

Welcome, it's best if you think of loops as code which repeats until a condition is met, that really helps simplify thinking

[verbal wraith]

This article specifies some flags you need to compile code with SFML

Not really a school question, but I tried dual booting linux via usb and it didn’t work: tried multiple usb sticks, two pc’s, and I did it by downloading the iso and putting it into both rufus and yumi (one by one not both at the same time)

Btw also tried fat, fat32 and ntfs

Does anyone have tips or things I can try?

[hidden badge]

imo, It's better to install the OS directly onto the hardware instead of using a live usb

[verbal wraith]

Can you define the problem you ran into

Just saying it didn't work doesn't help us

Maybe some screenshots

If you have

[wispy pollen]

Yeah I could try, do you have a yt tutorial or smth?

[wispy pollen]

Well I have booted ubuntu before and it worked just fine, now I downloaded BunsenLabs and yumi/rufus doesn't even show up

it shows in the list with devices in the boot section but then it tries to boot up from it, fails, and boots up windows

[verbal wraith]

Hmmm

Did you disable bios safe mode

[hidden badge]

What's your main OS and disk space?

[verbal wraith]

Safe booting mode*

[wispy pollen]

I havent done it on purpose but I could look into that, thanks!

[verbal wraith]

I think that's required if you wanna boot from a live usb to install the OS

What I'm doing a fresh install (I use arch btw), I partition my disk as follows : 512MB FAT32 for EFI partition, 2GB for swap partition, 30GB EXT4 for Root Parition and finally 69GB EXT4 (nice) for home partiton. Here's a video which pretty much sums up a basic install though I would recommend, as a beggininer, you skip the BSPWM installation part and install a fully fledged desktop environment like KDE Plasma for example. https://www.youtube.com/watch?v=yiouCwLtzHo

[unborn talon]

Swap will depends on stuff. Don’t just copy someone else’s swap

Also you can install bspwm and kde 👀

[honest hamlet]

I had this issue when I tried dual booting a live usb drive contain a flavour of Tails Linux. You need to disable legacy mode and enable uefi mode in the boot windows settings. You can find the boot settings by clicking F12 or whatever shortcut key it displays on the screen. Then disable legacy mode and safe boot option, enable uefi mode. Things should work fine then.

[deft summit]

any other windows to linux beginners having trouble. Ive downloaded Manjaro xcfe twice and each time i get past the dl i run into some weird inexplicable problem. I want to get a mac like dock and when i used the sudo command

1. I cant see my password. i know it hides it on purpose but it indicated that i was typing it before (at least i think)
2. It must not be typing at all because i use the same password for login and admin and it keeps saying wrong password but i know its right

[dusty dove]

Where exactly are you stick?

Maybe your password is just wrong. Typing without feedback is hard when you're not used to it.

Do you get any error messages?

[deft summit]

no it just said wrong password i checked to make sure caps wasnt on or anything

[dusty dove]

Maybe you set it incorrectly. Or you are using the wrong user name.

Is it a graphical UI or just text?

Anyone have recommendations on a foundational data structures & algorithm course or learning material? A little background: I've done CS50 and the Princeton Algorithms 1 course by sedgewick. I'm looking for something less complicated (less mathy) but will give me the strong fundamentals as I progress towards Leet Code, CITC, etc. I'm currently able to implement some basic data structures from scratch and explain use cases (Hash Tables, Heaps, Linked Lists, etc). Thank you in advance!

[verbal wraith]

There are two courses - one course by Stanford which is paid and one by Princeton

both on coursera

there's also an algorithmic toolbox course

[sterile robin]

thank you for your reply, I'll look into those courses. To clarify, is it another Princeton course aside from the one I mentioned?

Nope, same

Any Mac specialist here who can help me find out who manufactured the display of my MacBook air 2019? I had an LG display, but it got replaced so I would like to find out if I have a Samsung display now

[latent folio]

Are you looking for OOP sorta data structures? Like data-access objects, business objects, factories etc?

I have a good book, I learnt from (if I can find it)

[sterile robin]

I'm looking for a resource that will give me a foundation going into technical interviews, software engineering, competitive programming. Excuse my lack of familiarity with the concepts you described but I don't believe I'm looking for that but if you have an opinion on it I would be interested. Some more background: I currently am working with JavaScript, Java, Rust, Bash (in order of proficency). I have interviews for roles surrounding Full Stack Developer and Backend Developer.

[latent folio]

A lot of people are a fan of https://www.amazon.co.uk/Cracking-Coding-Interview-6th-Programming/dp/0984782850 for coding interviews, it's a lot of computer science-y algorithms. Also, I use https://www.hackerrank.com/ every now and then but that's mostly technical questions to improve your experience of using the algorithms. Best of luck!

I know some people use that book for prep for big 4 interviews

[sterile robin]

I'm currently working my way through that book and love it! I've just read online that the book may not be enough, especially for those without a CS background. Thank you so much for your help! I could just be overthinking and should just keep hitting the books hehe

[latent folio]

https://www.amazon.co.uk/Clean-Code-Handbook-Software-Craftsmanship/dp/0132350882/ is also a good book, I use it all the time and has improved my code massively but probably not hugely useful in an interview

[latent folio]

I've got that book and it's just collecting dust on my shelf, need to get back on it 😞

[blissful musk]

I strongly suggest just brute forcing your way into leetcode as quickly as possible. It sucks at first but you will progress like 100x as quickly. Just look at people's solutions in the comments and try to understand how they work. It is super hard to learn algorithms and data structures on your own without practicing. It will take literally years longer

If you are still at the phase where you like to learn from learning resources rather than solving problems, it will be near impossible to land a job. It takes time to get the mindset shift unless you get an internship or just force yourself to start

[sterile robin]

hehe I'm the same with the Rust book. Except it collects dust on the web 😅

[sterile robin]

Thanks for your suggestion! I think I will do both and work my way in leetcode and CITC. I definitely don't want to be stuck in course/tutorial hell at this stage in my journey so thank you for that.

[blissful musk]

I was stuck in it for a long time before I got super lucky with an internship. Remember, you don't learn things in order to do them, you learn things by doing them. This is especially true in programming because it's all patterns. The more patterns you've used, the better engineer you are.

To put it in perspective, people use leetcode to learn to code. So as long as you know if/else and functions you should be good to go

[latent folio]

Never a truer word, it is very practical

[normal ether]

Hi for an assignment I have to make a program that calculates the sum of a range of numbers, and outputs a string with an equation with the numbers in the range. We can't use any string manipulation and if the first number is greater than the second number it should say invalid. So far I have this:

starting_number = int(input("Starting number?"))
ending_number = int(input("Ending number?"))

sum = 0
expression = ''

if (starting_number < ending_number):
    print('invalid')

for x in range(starting_number, ending_number + 1):
    sum = sum+x
    expression = expression+str(x)

equation = expression  + '=' + str(sum)

print(equation)```

But when I run it, it shows invalid anyways, and also it doesn't output the string properly, it looks like this

Ending number?25
invalid
202122232425=135```
Sorry I'm really new to python

How do I fix the string, and also the if statement?

[pastel onyx]

Idk if you guys can see this but there are block whenever I see something with a black /grey screen and this is really annoying do you guys have any fixes for this

[vernal bridge]

1. you've got the wrong comparing sign, change it to 'starting_number > ending_number'

2. add 'else' before for loop

3. for adding white spaces, you can add after str(x) + ' '

[verbal wraith]

I think the first one was based on standard graph flow algos

was still reading the second one when it vanished in front of my eyes

[gleaming trail]

yep i planned on doin a depth first search for the first one to find max flow recursively from the bottom up and keep record of optimal path so O(V+E)

second one was how you would test for k-colorability in a graph

particulary a bipartite graph

[verbal wraith]

Yeah i forget

does a two colorable always have to be bitpartite

[gleaming trail]

yep

[verbal wraith]

i know bipartite is two colorable

not sure about the inverse

[gleaming trail]

u wanna think about it or should i share my answer ?

[verbal wraith]

nah, i was just trying to remember if this is true or not

i know how to check for bipartite

[gleaming trail]

ah ic ic good stuff. these are basic interview questions so def good if u can create these algos

[verbal wraith]

can you send me those prompts anyway

seemed nice

[echo rivet]

can anyone tellme whats going on here

[glacial leaf]

n is a variable that hold the input casted as an integer.

don't know what's going on with a and b.

h is initialized as zero and so is i.

line 8 is a for loop

• = is what we use to increment

i + = 1 means the value of i is incremented by 1

as far as i know, u need to initialize x. idk how you put for x in a[:n] when u haven't initialized it but maybe there's smth i'm missing

print (h%2) means print the value of h modulus 2. so like...when h is divided by 2, what's the remainer? that's what it's gonna print

h+ = int(x)**int(b[i]). so += is an increment.

I've never seen an increment that doesn't look like line 10

but that's cuz im a beginner

[echo rivet]

wow tysm

sorry that i can't help you with lines 2, 3 and 9. i admit to my shortcomings.

I learned react about 3 years ago and i dont remember i single thing

[neat apex]

I'm guessing it's python, and I have 10 minutes to burn, so let's do this. 🙂
General purpose :
gets as input: amount of variables aka n, list of numbers aka a separated by spaces, list of numbers aka b separated by spaces.
goal: to calculate for each item in a aka x x to the power of corresponding item in b aka b[i] add all of them up, and then check if sum is divided by two
line breakdown

1. waiting for an input from the user input() and converts it to an integer(int)
2. inputs() always returns a string containing everything the user wrote until the line break(when the user presses enter) so if the user wrote for example "1 2 3 4 5 6" is a string containing numbers, but we want to operate on each number and not a string, so we split it. the split() function get a string, and returns a list of string, for example "10 20".split(" ") will return ["10", "20"]
3. same as line two
4. initiate h to be 0
5. initiate i to be zero
6. a is a list, so for x in a[:n] means: for each item in a, until the N-th item, do the following
   9)as we discussed in line two, each item in a and b is a string so we convert it to int int(x) int(b[i]) (b[i] mean the I-th item in the list b).
   next the * * just mean to the power of (3* *2 is 9)
   h+= is the same as h=h+ whatever
   10)we increment i by 1 to get the next item in b
7. % returns the remainder of dividing the left hand operand by right hand operand
   __a more readble code __

amount_of_items = int(input())
base_numbers = input().split(' ')  # no need to write the sep, as it's the first arg of the function anyway
exponent_numbers = input().split(' ')  # no need to write the sep, as it's the first arg of the function anyway

sum_of_powers = 0
index = 0
for base in base_numbers[:amount_of_items]:
    sum_of_powers += int(base) ** int(exponent_numbers[index])
    index += 1

print(sum_of_powers % 2)

Now is this ipad safe

[gleaming trail]

<@&717391911132069929> what is this sus link bruh 💀

[gleaming trail]

yeah i see what u mean; i didnt go too in depth i just basically laid out how i would run a critical path analysis to find the latest/quickest path to get everyone there

keep in mind this question should be answered in about 30 minutes so u dont have to be too specific

ill send what i put exactly in a bit

i think its reasonable

[verbal wraith]

So here's what I got

Directed graph, no cycles

Basically a tree

[gleaming trail]

i see, how r u sorting the tree tho ?

based on adjacency list of dependent batallion ?

[verbal wraith]

I thought a BFS should be ideal if we want the setup to be fastest

Since the lower nodes are dependent on the upper nodes

Didn't really give it a lot of deep thought since it's a bit vague but this is what I got

What'd you make of it

[verbal wraith]

There will definitely be a root battalion which doesn't depend on any other battalion otherwise there will be circular redundancy

So I thought running a BFS from that root should be ideal

[gleaming trail]

i feel like it could work but i feel like u could make it even faster. honestly that sounds like a pretty solid algo tho. i would just talk about the fact only 500 battalions can be transported a little more

[verbal wraith]

Yeah yeah, I'm sure my idea would use a little more thought

What's yours

[gleaming trail]

i split it up into two parts

i basically set up an event node graph

from there i used topographical sort to set up the path based on dependencies to one another

using critical path analysis i found the optimal timing to ensure all battalions were at their best potential at time of war ie no time wasted sitting around

i connected the ships 1-501, 2-502 to assure no time was wasted and only 2 trips were used

this is O(V+E) for the sort

[verbal wraith]

Ah okay yours does seem more thought out

[gleaming trail]

yeah we're studying graphs rn lolll

[verbal wraith]

I still think that this would give the same time for the completion of the setup

Since the bottleneck are the lowermost nodes

Still, a nice solution

[willow owl]

Hi! what link are you referring to?

[gleaming trail]

yep i see ur point the main problem is deploying the dependent battalions last

[gleaming trail]

omg i thought u deleted it the person alrdy did i guess lmAOO

it was "get discord nitro and GTA cheats" with a bit.ly link
