In what time for n=1000000

[modest wolf]

its this one int rev_num = 0;
while (num > 0) {
rev_num = rev_num * 10 + num % 10;
num = num / 10;
}

mah brain just stop when it come to math based

[spare bronze]

Oh I wasn't referring to that problem

I meant the one above that

I was so confused

[modest wolf]

oh ok my bad

[spare bronze]

Yeah I was thinking wait what it's not that quick of a problem.

[glad wyvern]

something like this ig

the is_prime function is very optimsed

not sure if it can be optimized even further tho

[spare bronze]

Just implement a timer quickly and let's test

[glad wyvern]

for n ??

lets try it for n = 1000

[spare bronze]

I'm not at my pc so only have a screen of a particular n

[glad wyvern]

hmm

one sec

i know you can do some timer thing using python

[spare bronze]

Yeah something like time.instant then stop and get the difference in times

[glad wyvern]

ye

[spare bronze]

It says it's explicit my terminal screenshots

Wut

[glad wyvern]

[spare bronze]

Nah

I crop it

It works now

[glad wyvern]

yea thats the reaosn

[glad wyvern]

oooooooooo

one sec

[spare bronze]

It's just a picture from the 80s

[glad wyvern]

lemme convert it in ms

[spare bronze]

And microseconds

[glad wyvern]

not sure what unit it is in

[spare bronze]

N=1e6

[glad wyvern]

man python is so dumb

but its fast

as in to implement

not in performance

better now

[spare bronze]

Cool

[glad wyvern]

its way less than that tho

ig

[spare bronze]

Its hard in python

[glad wyvern]

2377 ms is like 2.3 sec

there is no way it is that long

[spare bronze]

Very clean code though

[glad wyvern]

arigato

the is_prime algo is pretty famous

also as python is slow as snail it is really important to write efficient things in to else it will be a mess lol

btw what terminal are you using

looks sick

[spare bronze]

Yeah I was opting for a slightly more over the top method. After the competition I wanted to make it crazy fast. But someone could probably shave a few milliseconds here and there off my total In C or Cpp. Can't wait to see if other people have a go.

[spare bronze]

[glad wyvern]

tomorrow i will try it in c

you didnt ask the question?

and ik it says python but he doesent explain what he wants to do

[idle dew]

nvm man geez

[spare bronze]

Nah im confused

idk what you mean

can you explain

@idle dew

Im not that fast

[idle dew]

i meant

they approached in dm so i asked them to ask in this channel because i couldn't help so that's why i thought i could answer python there

and there is also still no question or?

[proud flax]

[neon inlet]

hi man

will she told ya

like u see those wave functions

i want someone to graph them to me in python language

[neon inlet]

like a script to graph them so they look like this ...

[idle dew]

im not sure if im right but do you think u could use matplotlib

[neon inlet]

actually they offered only python, i'm a physicist i study alot of stuff , programming was the hardest thing for me to understand it needs a huge concentration it's not really for me so i face struggles with it

nd now i gotta translate physics into scripts maan this is so damn hard ngl

[modest belfry]

yes

[idle dew]

ahh it's okay and matplotlib is btw only a library in python so you can use it

[idle dew]

damn thanks

[proud flax]

use a quantum computer

[idle dew]

w

[neon inlet]

do u know how ?

[modest belfry]

You can use it for the graph, but to make it, you need to describe the functions well for the program

[idle dew]

yes yes

[neon inlet]

L i'm stuck on normal computer already

[neon inlet]

do u know how ?

[proud flax]

search online

i’m sure there’s tons of people who have plotted these equations before

[modest belfry]

yup

[neon inlet]

show me or do me the script !!

i'll try it

[idle dew]

https://physicspython.wordpress.com/tag/potential-barrier/

[neon inlet]

i'm using pycharm ..

[idle dew]

i found this but im not sure how much of a help this is

[neon inlet]

yeah it's related to quantum tunneling

what is that holly

[modest belfry]

It is usually used when the question is either very difficult or must be written with this.
Otherwise, use the simulator.
writing code will not help u

[neon inlet]

i don't get u man

[modest belfry]

thank u😂

[neon inlet]

this is hella bad hh

[proud flax]

that is not even remotely related to your question

[neon inlet]

ikk

https://www.youtube.com/watch?v=EMq_QbyghMU

this is literally the video that explains what i need to graph

The Quantum Barrier Potential

wait is possible using plot The Quantum Barrier Potential python in chat gbt !!

does anyone can try it ??

[astral plank]

Do you use Jupyter notebook? You can test the code from ChatGPT in that

[neon inlet]

show me how it's done sir ?

[astral plank]

I'm not a sir but what exactly do you know about python? Have you even touched a script yourself?

You basically write in ChatGPT "Plot The Quantum Barrier Potential in python". It should write a script for you (although ChatGPT's coding abilities need lots of work). Then, you just copy the script and paste it in Google Colab if you don't know how to start up a Jupyter notebook server.

Anyway, I just did it. This is the output.

(I've 0 physics knowledge, I'm only a programmer so I can't tell if it's what you want)

[neon inlet]

nah it's a sin and co function written in euler form

it's a wave so yea

hey everyone, i have a problem i'm trying to do an alarm that makes a sound with a python program, but the problem is i can't download the playsound option

[spare bronze]

What operating system are you on.

[spare bronze]

Oh yes I can!

[uncut quartz]

visual studio

[spare bronze]

what operating system?

win/linux/mac

[uncut quartz]

oh my bad 😅 windows

[spare bronze]

Ok so

https://docs.python.org/3/library/winsound.html

Does it have to run on other os s ?

I have a cli timer that has a alarm both in python and in rust.

[uncut quartz]

i'm sorry i didn't understand

[spare bronze]

Is it only running on windows or does it have to be able to run on other operating systems.

[uncut quartz]

only windows

[spare bronze]

OK cool so winsound is your best bet

however if you want custom sounds

use the following

[uncut quartz]

ok thank you

[spare bronze]

one sec

import os 
beep_sound = "beeping.mp3"
os.system(beep_sound)

This doesn't work on windows I realise but (if you want it on linux)

One sec let me hop on windows and just quickly check the other thing i pasted workds

from pydub import AudioSegment
from pydub.playback import play

beep_sound = "beeping.mp3"
sound = AudioSegment.from_file(beep_sound, format="mp3")
play(sound)

(pretty sure something like this would work)

[idle dew]

I suggest to call a professional as well I built a pc for my friend and he was able to afford rtx and all of that stuff I selected the components but told him to call a professional as well

Thermal paste is like tricky too much or too less it’s hard to understand and like I guess dryer does the work sometimes but some cases it has not

The cooling problem might be with components

I recommend calling the company of the product as for warranty and fixing

[idle dew]

all good, the water cooler is dead, I have researched that the Enermax Aquafusion likes to get clogged and it already happened multiple times after 1-2 years to multiple people. I had mine for almost 3 years so Im still happy with that lifetime. I have put a stock amd fan cooler that I got back in the day with the cpu and it runs fine 35-45 celsius while surfing, youtube, discord and around 65 celsius on full load for a longer period of time. After the benchmark test, it cools immediately back to 40 celsius 👍

if you want to update it to windows 10, can't you just install windows 10 on a usb/external drive and boot it?

Hey can anyone explain the meaning of tautology in computers

it says if the result of any logical statement is always true or 1 for all input its is called tautology

but how can the result of any variable be ALWAYS true😭😭😭😭😭😭

[ember scaffold]

Cal Newport’s latest article talks about this

Look up “What Kind of Mind Does ChatGPT Have?”

[astral plank]

"All chickens lay eggs". This is a tautology because it's true in every scenario. Same with a variable in a scenario. For example, you have a variable weather=sunny, then your if statement involving that variable can be weather=sunny || !weather=sunny. This is also a tautology. If weather=sunny, the first condition is true, and therefore the statement is true. If weather=rainy, it's not sunny (duh) which makes the second condition true and again the statement is true. So no matter what the variable's value is, the statement is always true. Does this make sense?

yessssss it does make senseee nowww!!!

thank you soo muchhh!!!! <333333

I am working on a react app and I am getting a fetch error. I checked with postman and it is working so I am not sure what I am missing. I have been working on this all day T.T Can anyone help???

[severe bison]

I'm sorry to hear that you're experiencing difficulties with your React app. Fetch errors can be frustrating, but let's try to troubleshoot the issue.

First, it's important to determine what kind of error you're encountering. You can do this by checking the response that you receive from the server. If the server responds with an error code (e.g. 404, 500), then the issue is likely related to the server-side code. If the server responds with a successful response code (e.g. 200), then the issue may be related to your client-side code.

If the issue is related to the client-side code, there are a few things that you can try:

• Check the URL: Make sure that the URL that you're trying to fetch is correct and matches the endpoint on the server.
• Check the headers: Make sure that the headers that you're sending in the request match the headers that are expected by the server. This can include things like authentication tokens, content types, and accept headers.
• Check the request body: If you're sending data in the request body, make sure that it's formatted correctly and matches the expected data format on the server.
• Check for CORS issues: If the server is on a different domain than your client-side code, you may need to enable CORS (Cross-Origin Resource Sharing) on the server.
• Check for network issues: Check that you have a stable internet connection and that there are no network issues that could be preventing the request from reaching the server.

If none of these steps resolve the issue, you may need to consult the documentation for the library that you're using to make the fetch request, or seek further assistance from the community.

[hot falcon]

can anyone help me understand what the % means in java code

if (number % 2 == 0) {
System.out.println(number + " is even.");

[zealous thorn]

modulo operator

returns the remainder when 2 integers are divided

e.g., 55%13 = 3

[gray mesa]

I need to draw a huffman tree using those frequencies/characters. i’ve seen trees with multiple pairs of sibling nodes on the same level, but idk when I’m supposed to do that

[open solstice]

you basically start with leaf nodes, select the 2 letters with lowest frequency, put them to leaves, create a parent node for them and give the frequency of the sum of their children, then add the parent to the list you have with it's frequency, and do the process over and over

[gray mesa]

I get that part, but how do huffman trees end up with more than 2 nodes per level 🤔 i've seen many examples like that

[open solstice]

it's about the frequency of the parent

if the parent doesn't have the lowest frequency, you basically have to create some other leaves on the same level

[gray mesa]

OHHHH. this makes so much more sense now, thank you

there is a panda.concat() function so that solves the merge thingy . and the you can just plot a simple graph setting one axis as temp and one axis as date

Check out "Dissecting Minecraft" by LogicalGeekBoy on YouTube, cool playlist about redstone

But personally how I learned Minecraft redstone was through just trial and error

I looked up tutorials on redstone stuff I wanted to build, followed the tutorial, and eventually learned something new from that

If I came across something that was foreign to me I would research on it and watch videos about it

After all that I learned enough to make my own stuff

completely forgot how redstone works though because of academics

i was very into minecraft during summer 💀

[craggy stream]

hi guys, i'm new here and i'm searching for a good laptop. what brand is the laptop he uses in the videos? and what laptop do you recomend for university?

Hi, I already have an existing ERD but I don't know how to make it to diagram. Can someone help me?

[tame violet]

Has anyone tried rendering a decision tree based on the training data of 922509 instances with graphviz? My teacher asks me to visualize the tree with graphviz but when I execute this code, it stucks forever at g.render()

dot_data = export_graphviz(tree, filled=True, rounded=True,
                               feature_names=['S1', 'C1', 'S2', 'C2', 'S3', 'C3', 'S4', 'C4', 'S5', 'C5'],
                               class_names=['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'], impurity=False, out_file="tree.dot")
    with open("tree.dot") as f:
        dot_graph = f.read()
    g = graphviz.Source(dot_graph)
    g.render()

anyone know of any good android emulators for mac? everything ive tried isnt compatible with the m1 chip

[frank geyser]

Blue stacks maybe?

[upbeat bloom]

not compatible

its okay though i gave up

[zealous thorn]

android studio?

[upbeat bloom]

i tried but it took too much effort to navigate

[zealous thorn]

lmao

what do you need the emulator for

[upbeat bloom]

sims freeplay

the greatest game of the 21st century

[zealous thorn]

is there a stark difference between sims freeplay and any other sims game

[upbeat bloom]

yes sims freeplay is a lot worse

but its a lot simpler since its old which is good news for me

its mostly just a nostalgia thing i used to be addicted to it so its just cute to play again

[zealous thorn]

are you sure bluestacks doesn't work?

https://www.laptopmag.com/news/macbooks-with-m1-can-run-android-apps-with-this-software-what-you-need-to-know

[upbeat bloom]

yeah i tried

also i googled it and it said its not compatible so thats weird

[zealous thorn]

i guess you will have to do without sims freeplay

[upbeat bloom]

no its fine i have it on my ipad

:3

[idle dew]

nox app player, genymotion, LD Player app, MEMU Player

[zealous thorn]

?????

[idle dew]

you should try nox app player

[upbeat bloom]

i did, it got stuck on 99% when downloading and i couldnt figure out how to fix the issue

[zealous thorn]

⏰

[idle dew]

99% issues are shit

[frank geyser]

Weird bluestacks doesn’t work

[zealous thorn]

bluestacks doesn't work but my stack is blue 💯 💰 💸 :benjamin_franklin:

[zealous thorn]

no it came from identity fraud

remember those north korean hackers that stole 1bill from bangladesh

it was actually me 😳

[frank geyser]

[zealous thorn]

did you end up trying those questions

[frank geyser]

Chinese North Korean hacker

nah I just ended up playing valorant til 1 with my friends

We played a comp game that went like 6 or 7 overtimes

[zealous thorn]

c9 vs faze

[frank geyser]

Took forever

[zealous thorn]

would you be on team na or team europe 🤔

[frank geyser]

Europe lmao

Europe cracked at esports

[zealous thorn]

faze > c9??

uncle sam would be disappointed

[frank geyser]

Faze bad

[zealous thorn]

faze was eu 🤦

[frank geyser]

They still bad

[idle dew]

what about fnatic?

[frank geyser]

They annoying

[idle dew]

anyone know a service or something people can use to manage teams and monitor their progress on stuff. - and like share data etc

like make a peer to peer network kinda

[dapper niche]

trello, asana, jira, etc. something like those?

[amber mountain]

which schema is better? the start schema or snowflake schema?

[idle dew]

Slack and Github probably

[eager olive]

always found trello to be very easy to use

[jade summit]

I think GitHub has a good kanban board for group projects. Jira is good for organizations

[idle dew]

thanks

[dapper niche]

I'm surprised there's no e/mechical engineering or computer science channels. They all get lumped into tech-related?

I mean those are basically #science-help lmao

[graceful trail]

does anyone know if Onyx Boox tablets work in America if you buy them off AliExpress

[hot fable]

it will work but you might have to change the language localization

[graceful trail]

okie thank you sir

[old breach]

can anyone help me with this question? Theory of computation has been really challenging me :''D What does overlapping mean exactly?

[median cloak]

Hi guys,i bought a thinkpad x220 for 40 euros (8gb ram, i5 2620M, HDD 320gb). Is it a good deal?

[spare bronze]

Depends if it turns on 🙂

[median cloak]

it works

[fallen timber]

In the context of pattern recognition and the specific problem of detecting a sequence "1001" in a given input string, "overlap" refers to when two instances of the target pattern share some common characters.

For example, consider the input string "11001001". If we were looking for the "1001" sequence without considering overlap, we would find two instances of the pattern:

The first instance starts at the 2nd character and ends at the 5th character: 1(1001)001
The second instance starts at the 5th character and ends at the 8th character: 11(1001)
Notice that the two instances share common characters (the '0' at the 5th position and the '1' at the 6th position). In this case, we say that the two instances of the "1001" sequence "overlap".

When we design a DFA to detect the "1001" sequence without overlap, it means that the automaton will only recognize non-overlapping instances of the pattern. In the example above, it would recognize the first "1001" sequence, and then reset its state, ignoring the overlapping instance.

[lapis perch]

Does anyone here use notion? Because when I use headings in Notion [I'm specifically using the "mono" font] heading 1 & 3 uses serif instead of mono. is it just me or everybody?

[burnt forge]

does anyone know any good extra curricular activities i could do to beef up my personal statement. I want to major in computer engineering like James

[nova basin]

I don't think there's specific extra curricular activities tht help with what major you take but "All work and no play makes Jack a dull boy". Practice your logic thinking more by playing sudoku, chess, etc. Any sport or routine that helps keep you fit already good. Again, this just an opinion.

[burnt forge]

ok thank you

[graceful trail]

nah it's a bug and I have no idea when they'll fix it

[graceful trail]

cyber defense team

[burnt forge]

huh? could you explain a bit more please

[graceful trail]

yeah

idk where you are but in America some schools have a team where they do cyber capture the flag on networks and OSs and stuff

its lihe the thing that cybersecurity nerds do in school

but it looks good to be well rounded in engineering and in that type of thing as well

[burnt forge]

Yeah but tbh im not insanely smart but i would be interested if it was mainly learning about cybersecurity

[dapper niche]

there are volunteer/charitable organizations where they specifically have volunteers that work on software. https://www.developforgood.org/ (not an endorsement, just an example that I googled). Also don't know how personal statements are critiqued, just an idea for you to consider

[burnt forge]

ah ok tysm

[brave wagon]

Anyone familiar with machine learning here
I needed some help as i want to learn ml but i am so confused reading so many ways to start it on internet
if someone can tell me what i should focus on if i am starting out machine learning

[dapper niche]

there's a few free online courses from universities using python. why not start there?

[brave wagon]

it would be nice if you can suggest me some...

[brave wagon]

cause everyone just teaches the high level stuff and do not explain it in detail

[dapper niche]

sorry I don't have personal experience with any of the courses, but that's what I would do -- take one course and then see where I would want to expand on next

[brave wagon]

sure i will.. thanks

[azure pivot]

does anyone know on how activity diagram work?

[soft horizon]

in uml?

[lost gull]

@keen girder @trim rock is this possible?

[trim rock]

Yea

What help do you need tho?

You can mill at step intervals or at 45 degree angles

[lost gull]

one angle is 32 and other is around 40-ish

but important question will the tool break

is not

i can just make g code go from point a to b etc.

or i could mill out square part and then work on sides

[trim rock]

What you milling?

[lost gull]

aluminium

[trim rock]

What is the size of the thing?

If its above ~5 cm deep then do a-b

Or else the bit will break fron lateral stress

[wheat vector]

theres a React course im taking online. its really hard to pay attention to. i start the vid and i just get bored

one time it was playing and 2 secs in I ended up playing games on my phone

[azure pivot]

yes

[soft horizon]

It basically shows the flow of activities than occur in a system depending on what the actor does

[azure pivot]

so, let say that i want to make an activity diagram about payment in club memberships. Where it can use third party payment like paypal, visa and etc.

so is there like 4 actors in that diagram?

user, admin/staff, system and third party payment?

or the third party payment is like inside the system?

[lost gull]

sorry my internet went out

[soft horizon]

Yes

[lost gull]

200x50x50

aka x 200 y 50 z 50

depth of this channel is 25 width is 60

[soft horizon]

also if the admin/staff perform nothing during the payment process then no need to consider them as actors

They also come under the third party

[azure pivot]

they can view the payment and make a membership cards for the user

after the payment has been confirmed

[soft horizon]

viewing in usually not considered as an activity in activity diagram

if they are making the membership card then yes they are actors

[azure pivot]

so the admin/staff is more of like verify the payment data?

and also manage the payment?

[azure pivot]

or they can only do this?

[soft horizon]

Yeah both verify and manage

[azure pivot]

manage the payment data?

[trim rock]

Mm or cm?

[soft horizon]

Yes they can make changes to the database where the payment histories are stored

[azure pivot]

ahh yeah you're right

thanks a lot!

[soft horizon]

anytime 🙂

[lost gull]

mm

[trim rock]

Yee just make the bit go layer by layer from a to b. Working on the sides will lead to the bit breaking

Or if you rich buy a fancy bit and go crazy

[dapper niche]

If you're asking for help, my advice is to find a project that you're excited to build and then when you're viewing educational materials, keep thinking about how what you're learning applies to the problems you're trying to solve in your project. The best way to learn software development is to find something you're excited to build, in my opinion.

[lost gull]

@trim rock can you help me think of any other way to make this shape

[trim rock]

Divide the volume the be milled into layers and then mill it layer by layer

Like how 3d printing workes but u mill

[lost gull]

ik i mill 2mm at once

i will just end the work with 1mm cutter so it can be as fine as possible

[trim rock]

Oke

[trim rock]

Wait cutter wat?

[lost gull]

this things

[wheat vector]

i dont really get excited to build projects. i was more so talking about staying focused on online courses

[dapper niche]

right, I meant if you could relate your online courses to something that you're interested in (for example, an exciting software project), it'll help you keep focused. There's usually a way to relate something uninteresting to something you're interested in.

[wheat vector]

im interested in getting a job in tech

so i could use the things i learn from the course and use them for my portfolio

[dapper niche]

that sounds like a good idea. I would recommend keeping specifics in mind of what you might want in your portfolio so that things from the course will catch your attention

and in general, if you are struggling to do something uninteresting, maybe challenge yourself to do 5 minutes instead of 2. Then increase as you get better, like strength building. Make it harder to get distracted (put your phone somewhere far, etc.)

[lost gull]

@trim rock its finally done

[hoary anchor]

anyone know what the ereaders are that james recommends?

[wheat vector]

okay thank you

[dapper niche]

he uses the hisense touch and a variety of boox readers

[hoary anchor]

easy thank you sm

[trim rock]

Oh a ball bit

[trim rock]

Oke how did it go?

[dusty basalt]

anyone here use mobiussync (https://www.mobiussync.com/) on their ipad? wondering about the safety and ease of use since i have a windows laptop and an ipad

[misty ibex]

heyy guys

can someone please recommend me a habit track and a pomodo timer?

[dusty basalt]

ticktick

[misty ibex]

Im tired of testing strange apps that looks unfinished

its been so long that im in this search hahahha

[misty ibex]

im going to try it, ty

[dusty basalt]

from the top of my head theres also focus to-do but idk if it has a habit tracker

[misty ibex]

i prefer cron in this way, because they are doing an integration with notion and i use notion every day

but ty anyway man

maybe one named "resulvity" its paid, but its really cheap and looks good

to pomodoro

is that "forest" good 4 free or its paid too?

[dusty basalt]

depends on what device ur on

it's free on android paid on ios

there's a free extension too for browser

[lost gull]

i just need to make more documentation but everything is el ok

[desert cipher]

hey, has anyone ever tried to upload a django project to vercel?

i'm getting this warning:
WARN! Due to builds existing in your configuration file, the Build and Development Settings defined in your Project Settings will not apply. Learn More: https://vercel.link/unused-build-settings
and i have no clue what's wrong

[slender mulch]

https://github.com/thgh/vercel-sapper/issues/61

[slender mulch]

i found this in the git repo for vercel

i think this is an issue other people faced too

see if you can find any resolves in the issues section here

[misty ibex]

im searching to a pomodoro timer 4 desktop and chrome extesion or app. Its is being more hard than i thought ahahha

none have all the config, they are simple imcomplete

the only problem in ticktick to me is that sometimes i have to do other things and if i do so i lost my actual track, i cant just track an unfinished cycle

[misty ibex]

i finally found it hahahahah its simple but works perfectly 🥹

[dusty basalt]

i mean u can just use a discord bot like pomobot or pomomo

or set up ur own timer even

oh w8 what did h u find

[misty ibex]

pomodoro-tracker

[dusty basalt]

yooo

[misty ibex]

its true haha i never put discord on options but its a really good tool too

I mean, Midjourney is here

[twilit anchor]

Question, why are people using Visual Studio Code and not Visual Studio? Genuine question

[dusty basalt]

imo vscode starts up quicker and was easier to set up

i think vs is closer to an ide and vscode is closer to a text editor

correct me if im wrong

[dapper niche]

there's a bunch of different answers...definitely something better to google. one main difference is the licensing scheme and plugins

[heavy garden]

If you work in a solution with hundreds of thousands of line, VS is a bit slow to boot

[unkempt ore]

just go vim

[compact bay]

Hello guys I just weanted to ask for ppls opinion about the project that am planning to make, I wanna make a portrait img of my mom but the details is made of code (dosent have to work tho) but they should all form my mothers face

can u guys tell me if this is possible?

its kinda like art but its a bunch of code group together to form an img

PLEASE DM ME if u guys can help or have time I WOULD REALLY MEAN ALOT thank you in advance

[dapper niche]

yea, what you're looking to do is something very similar to something like "jpg to ascii" <= I recommend googling that

the issue you'll have is that the code needs to be verbose, otherwise the whitespace will not be able to "draw" anything...unless you handle drawing in the whitespace in some other manner. It just depends on what code you're using. For example, if you're using minified JavaScript and line wrap it, it'll just be a ton of seemingly random characters that you can use...but technically, it'll be code

[compact bay]

line wrap or minfield should do

[dapper niche]

you'll have to look for a tool that will allow you to do custom text, but if you can't find one, are you going to build one yourself?

[stuck breach]

Hey guys so I'd like to get into photography / videography and i managed to find a usedSony Alpha A6300 in excellent condition at €544, what do camera-savy peeps think? is it a good starting camera?

[winged oxide]

I'm reapplying to go to Uni for either Computer Engineering or Computer Science (depends on which of them I get into) after having studied Computer Engineering once before and it not working out due to me moving to a new city during Covid and struggling there extremely when it came to mental health. Essentially wasted 3 years there doing nothing and racked up an insane amount of education loan, but now I'm reapplying to try to study again, because even though I didn't learn a whole lot academically, I learnt a lot through the experiences I had there and now I'm eager to throw myself back into studying.

But there is still a while before I need to go back to school (doesn't start until August) so right now I'm just working, and depending on when I finish work, I try to sit down with some coding courses and crank out some modules here and there. I did the C# modules on Microsoft Learn and it has now helped me a lot in gaining basic knowledge about writing and formatting text in C#, but there was not much else it taught me.

So I'm looking for either a C# course that builds upon what I've already learnt or a Java course for beginners, preferably free because I'm STRAPPED AF for cash right now

[winged oxide]

I have a Gen 4 iPad with a Retina screen that's not in use and I want to use it for something, but I don't know what to use it for, any recommendations?

[frank geyser]

Use it to take notes and organize them

[dapper niche]

I'm actually very experienced in C# and dotnet. I won't recommend a course for you because you can find them easily if you google, and I haven't done them myself, so I wouldn't know which to recommend. However, I'll give you some other food for thought:

1 - See if you can get a C# book online or in the library. Sounds like you have some of the basic basics and just need to fill in some details. This will help you a likely help you a little with your first classes. This is 100% what I would do myself if I can endure the potential boredom.

2 - Learning a language more is not that likely to give you a boost in starting CS, IMO, but it depends on your school's curriculum and schedule. I would look at the schedule for your school and see what topics you'll cover during your time there. Then, I would see how I would cover it by learning C# more. Chances are that you'll have to do something completely different to cover those topics, but maybe C# will provide an environment for you to investigate those topics. Feel free to ask about those specific topics and we can see if there's a way to get a head start on covering them.

[dapper niche]

3 - Leetcode. There are curated lists of problems out there. This will be a very difficult way to learn because you haven't done the coursework, but it'll be very valuable. Try to tackle the "easy" level questions and look up the solutions to them and learn. This will get you experience leveling your logic writing and code reading skills.

4 - If you're more interested in learning software development and not concerned with how well it will get you a head start in school, start learning some widely used components/types of technology, and you can do all these in C#/.NET. Learn how to read from a file and write to a file. Learn how to create and host a Web API (it's literally called Web API in .NET). Learn how to create and host a basic SQL database and perform basic queries -- you can use SQLite to skip a lot of the other setup steps. Learn to host a web front end (HTML/CSS/JavaScript.) This section is the most professionally relevant and will allow you to discover what you're most interested in and give you a foundation to start building your own personal projects.

5 - If you're into gaming, you can do learn Unity because it heavily uses C# and you can leverage your passions to keep you going.

[winged oxide]

This is a ton of great information, thank you sooooo much❤️❤️

[winged oxide]

I'm thinking of using it to take notes but I'm worried about the lag, the reason the iPad is not in use anymore is because of it becoming slow and unreliable for the use it was put through, which technically wasn't a lot

[dapper niche]

maybe try a factory reset. doesn't sound normal for it to slow down significantly

[exotic coral]

Hey anyone here familiar with html coding?

I am trying to produce a hoverable dropdown menu in Husbpot email, but I am experiencing trouble with it

I tried the following code:

<div class="dropdown">
<button>HubSpot Resources</button>
<div class="dropdown-content">
<a href="https://blog.hubspot.com/">Blog</a>
<a href="https://academy.hubspot.com/">Academy</a>
<a href="https://www.youtube.com/user/hubspot">YouTube</a>
</div>
</div>

But instead of a dropdown menu I get this

[winged oxide]

Hmmmm, any note taking apps you recommend? Ans also something to note take with as in a stylus or something? I don't know if the Apple Pencil is supported or if I have the budget for it lol

[unkempt ore]

yes because int temp is not a pointer var

[dapper niche]

your links are malformed. The end quotation is in the wrong spot, unless discord just mangled it.

putting * before the pointer variable dereferences it and returns the value. It's not due to temp not being a pointer var, but due to the * in front of p1

[winged oxide]

I'm thinking of using an iPad 4 for notetaking at the Uni I will get into in August, it's a bit slow so I might factory reset it, but the Apple Pencil won't support it so what do you recommend me using as a stylus for it? And what notetaking apps would you guys recommend?

[loud marsh]

notability is the best note taking app, it only downsides that it have a yearly subscription (maybe 10$ depends on where you live)
there's some other great free apps (the default one, Microsoft OneNote, LiquidText)

[winged oxide]

did not know it was subscription based, for fuck sake

it seems like they might have a education plan where if your school is eligible, you can get the app for free, i'll try and contact them and see

[loud marsh]

its free but after some time you cannot highlight stuff and there are some limitation in the free subscription

[loud marsh]

try that it might work, worked for me with other apps

[winged oxide]

seems like goodnotes is something a lot of users of notability migrated to after notability introduced their new subscription model, might take a look at that

[winged oxide]

it's just a bit difficult to know if it's available for free or not for me because of me not being enrolled in an university yet, I'll experiment and see tho

[loud marsh]

it looks like a good app ! might move to it lol XD

[winged oxide]

if you do, please tell me how it is, DMs are open:-)

[loud marsh]

Will do :D

[spice pivot]

i use goodnotes and i think its great! there is a one-time fee but it does everything i need it to :))

[winged oxide]

We have now moved up to a iPad gen 5, which also was just laying around lol, screen is semi fucked (it works and the touch works fine, but it just scrolls on it's own sometimes and the home button is a little bit pressed in) but I might just buy a new screen and possibly a new button and fix it up and see if it works

[winged oxide]

Good to hear, will look into it, I assume you use a Apple Pencil

[spice pivot]

yeah, my ipad broke recently so i made an investment and got the new ipad & apple pencil

[winged oxide]

Which iPad did you use before?

[spice pivot]

if you have the funds available i would definitely recommend, the new apple pencil is so cool - you can double tap to swap between pen & eraser which i use all the time

[spice pivot]

i had my brothers old 6th generation, but one day it just stopped turning on lmao

i took it to my local apple store and they said there was nothing they could do

[winged oxide]

I would love to, but when I move to wherever I get my uni place I need to work to support myself financially, and after using it on both rent and food, I don't know much I'll have left to use for personal stuff

[spice pivot]

yeah of course i understand completely

[winged oxide]

But if it had apple care, most likely they would have moved heaven and earth to fix it

[spice pivot]

im hopefully going to be in the same position in september so im quite lucky that this happened over summer so i have the tech ready for uni

[spice pivot]

ofc 😂

[winged oxide]

What are you bringing into uni when it comes to tech? I'm working right now so I need to start buying stuff that I'm thinking of bringing

[spice pivot]

im quite a big tech person so ill probably be bringing quite a bit more than most 😭 but i have a laptop and an ipad that i currently use for college, im gonna bring them both and see which one suits my course more

and also potentially a monitor if my mum doesnt need it for work

but i really dont think anyone needs that much :) im just a bit extra aha

[winged oxide]

I had a laptop and monitor only, and then I ended up buying a whole ass desktop and a second monitor, so I came back home with a desktop pc, two monitors, a router and a WHOLE BUNCH of wires

My dad was pissed lmfao

[spice pivot]

also one thing i would suggest is not buying stuff before you go! if you've got enough money rn, i recommend putting it aside for once you start

because its hard for you to know what you'll use

[winged oxide]

Smart, I have stuff already I think, I'll bring one of the two monitors, an external wireless mouse I already have and that should be enough I think

[spice pivot]

its probably better off waiting until you get there then figuring out what works best for the course youre gonna be doing

[spice pivot]

haha thats so funny

i have so many wires that ive filled my extension cord so i have to swap around the wires that i need

[spice pivot]

sounds good :))

[winged oxide]

I think that's smarter on my front, both financially and just generally for the amount of stuff to bring over there regardless

[winged oxide]

I did this too....with a 10 input extension cord

[spice pivot]

omg 😭

[winged oxide]

I was a fiend at my previous place

[spice pivot]

aha clearly

[dapper niche]

outside of hardware, highly recommend getting a system where your documents are sync'd and accessible from any device. hopefully, this handles backup as well so that you never accidentally lose important data/documents

[winged oxide]

Like software based? Any recommendations? I have a windows laptop and might possibly use an iPad for notetaking, if everything for the iPad is fixed that is, in terms of the screen, Touch ID and acquiring a good stylus

[dapper niche]

there's a ton out there, but I know dropbox used to be really popular

[winged oxide]

Keyword: used to, it's a subscription plan now and I'd rather make my own webserver to store my docs with drives I have laying around rather than pay for it, but before it comes to that I'll search around

[dapper niche]

You can still get a free account: https://www.dropbox.com/basic

another alternative if you are willing to start learning git (really useful in the industry) is use github

[winged oxide]

Feel like the free one will fill up quick since it's only 2 gb, but maybe not if I just have it for notes

[dapper niche]

yea as long as you don't have games or large videos in there, it should be enough

[twilit anchor]

Google drive gives you 15gb for free

[blissful matrix]

Hey, does anyone here have some experience with the Samsung Galaxy Buds 2 and Buds 2 Pro? Can't decide, which one to buy

[unreal bridge]

sus:)

[winged oxide]

Whichever one you have the budget for tbh, I've really tried using earphones for a while but none of the ones I've tried sit in my ear (and I've tried tens and tens of pairs, both wired and wireless), so with this situation, using a wireless one, the chance of me losing one or both is huge so I've just stayed away from them altogether and only use over ears. But I've heard solid things about both from my friend who bought and used both tho

[winged oxide]

true, I'll look into sorting out my existing google drive and see if I can make it work for my notetakings

[terse harness]

if u have spare pc and drives lying around just setup like a network drive. kinda like a home server, and then learn some network and vpn to ur server from anywhere else outside to access ur files

[winged oxide]

so like my own personal cloud? from what I've heard this doesn't require a ton of resources and and there are a ton of guides out there to set this up easily, I'l look into it, this might be the way I'll go tbh, and plus I've always wanted to try and do this once, maybe with a raspberry pi or something, but I'll defo look into what the best and most practical way to set up this for me will be

[terse harness]

u can run it completely off a raspberry pi if u wanted to. it depends on the scale of your server / setup

i personally use wireguard, samba and zfs on a linux server that sits in my closet

[winged oxide]

i bought a desktop gaming PC on which I tinkered with Fedora Linux through VM to possibly fully convert to Fedora on my laptop possibly (it was fun, but I didn't get too far unfortunately), but I've been thinking about fully diving into learning Linux, which distro are you using? And how long did it take to setup your server?

[twilit anchor]

That's a thing?

That's amazing!

[neon dock]

would it be possible to mod a cd player by taking the guts of a nice cd player/speaker and putting them into the housing of a less nice cd player

this is my idea

[twilit anchor]

How would one be capable of doing it?

[glad wyvern]

yeah it would defo be possible

but if you want it to be sturdy then u would be required to 3dp many blockers

[dapper niche]

is this the nice one or the not nice one?

[neon dock]

this is a not nice one, i think it was originally made for children

but how funny would it be to have a sleeper cd player

with hello kitty housing

[dapper niche]

why CD player, though?

maybe just put a bluetooth speaker in there

[neon dock]

getting into cds and physical media lately

bluetooth could be an addition

but it would be awesome if i could make it play cds

[dapper niche]

yea, I really like this idea

wow, it's not cheap!

Hello! Do anyone have advices on programming interviews? I am a 2nd year soft.eng student and currently my school changed their marking system to have a programming coding interview at the end of every assignment - students have 30 mins to solve 2 relevant coding interview questions. I do not know how I should prepare, hence seeking help.

[wheat heart]

Anyone know how to wipe all my drives from bios, I was running Linux and I wanted to go back to windows and everything broke 💀. I’ve been trying to figure out how to just clean wipe both of my drives but Linux won’t let me since it’s installed on one of them

I’ve tired installing windows onto the drive but it still won’t let me (windows installation media)

and I went to bios(msi) and I can’t find where to do it

[dapper niche]

is it a mock interview where you interact with the interviewer, ask questions, and work together? or is it just you solving a "whiteboard problem" on your own?

[dapper niche]

boot windows installer or portable linux install running from a USB thumb drive is an option. Then, access the disk utilities from there

[wheat heart]

I tired that but ima do it again when I get home

[dapper niche]

you would also go into bios and change your boot sequence to USB first so that it doesn't try to boot from the installed drives

[wheat heart]

I got to the installation media and disk management but it wouldn’t let me format my ssd

[dapper niche]

what was the error?

[wheat heart]

I got it working

i used diskpart in the command prompt of the instlation media and just cleaned all my drives

[dapper niche]

nice

[wheat heart]

thx for help

solving whiteboard problems on my own

[idle dew]

Anyone use VIM here ?? I need a help

[dapper niche]

look up neetcode. there's a 150 curated questions of leetcode problems with video solutions. that's how I would prepare for whiteboarding interviews in general, but for one administered by school...they would have to be asking you about problems on topics that they covered specifically. Maybe they can tell you more about what to expect? Either way, some of the primary skills in general will probably be...

• identify what the problem and what category of problem it is. then, determine the category of solution.

• exam the test cases that they give you (if any). Come up with your own test cases. A test case would be something like "if the input is [0, 2, -1], what would I expect the output to be?"

• come up with a high level solution as a description or pseudocode. Run your test cases through this potential solution.

• Write the code and then run the test cases again through this.

For actual interviews, though, you would do some other things because you can communicate with the interviewer.

for real interviews, I recommend this: https://www.youtube.com/watch?v=DIR_rxusO8Q

Hi tech newbie here.
I have:

• Laptop A
• Laptop B
• Monitor C

It looks like the laptops have 1 HDMI port, while the monitor has 2 HDMI ports
I want to make Laptop A my main device
Laptop B and Monitor C will be my external displays.
How do i achieve this? how many HDMI cables do I need? Will I need a HDMI to USB converter?

[dapper niche]

if you have windows, you can use an HDMI cable from laptop A to monitor and configure it to extend your desktop. Then, use windows wireless display to use a separate computer (laptop b) as a monitor. However, there will be some latency.

[exotic gazelle]

awh, do you think its possible to do without wireless connections?

[dapper niche]

I'm not sure, it's worth a try. otherwise google something like "use laptop as second monitor -wireless"

[exotic gazelle]

oki thank youu

[winged oxide]

From the laptop's start menu, select Settings. Choose the system and then Projecting to this PC. Now on the primary device (desktop), use windows+P and click Connect to a wireless display link showing at the bottom. Quote is from IndiaTimes.com

sorry in advance for the long text, but to sum it up i have a very large dataset about Australia weather, and i want to create 2 graphs:

1. a graph that compares the average rate of wind gust speed of 5 different cities throughout the years 2010-2017.
2. graph that compares the average rate of temperature rises of those same cities throughout the years 2010-2017.

i think the best options are to create a line plot or an area plot, but the coding part and filtering the data is where i'm having trouble

who knows how to change ip adress and etc?

like who is the pro in this local area network and etc.

in addition will there occur problems regarding to the change?

[soft horizon]

What code did you write for this?

DM me the dataset

[proper hound]

ggplot(filtered_data, aes(x = Year, y = WindGustSpeed, color = Location))

• geom_line(size = 5) 
  

• labs(x = "Year", y = "Average Wind Gust Speed", color = "Location") 
  

• scale_color_manual(values = c("Sydney" = "red", "Albury" = "blue", "Brisbane" = "green", "Penrith" = "orange", "Melbourne" = "purple"))

[dapper niche]

the most basic thing to try would be to download any software or drivers from your laptop manufacturer's site. Otherwise, maybe the touchpad got disabled accidentally somehow, so I would check to see if there is a way to have done that and then undo it

[placid grail]

Only advice is practice
Try to learn thing by thing even if you cant see improvement right away

Do tutorials on youtube as well as some quizzes and stuff online

Many platform offer help like w3schools and more

[hardy gate]

thanks for your advice

I will try but I scared

[placid grail]

Don't be, if you are scared u will never learn

U have to accept and be open about it

Dw u will do just fine

Python is an easy language don't let it scare you

[hardy gate]

Okey, I just worrying about the days will not enough to be successful because I have only 8 days left

[placid grail]

I mean what happend happend

Focus on whats now and whats comming

8 days are good to start learning

Everyday learn something new

Like i said if u say you wont do it, u will believe it and u won't

Be open abt it

People can do crazy stuff in 8 days il tell u that from experience

The hardest part is the start

[hardy gate]

Okey I will do it. And, after the exam I will write here. (: I'am motivated thanks for your time

[hardy gate]

the hardest part of the programming exams is the mental part imo

if you are not stressed during the exam you'll do better

if you have questions just put them here

worrying won't get you closer to your goal. Turn that anxiety into action! Python is an extremely popular language. There are resources everywhere. You should be able to find answers to anything that you need very easily.

Hi everyone im barely beginning to learn some code and I was following my prof video and when they typed their "else" it did not underline red and mine did. As far as I could tell there were no differences between our code and it will not let me save until I fix 😦

[dapper niche]

line 45 has an opening brace, but it should go on line 44

the code that you have effectively written is an IF statement without braces. When you do that, only the immediately line after is part of the IF statement. Then, when you have braces starting on line 45, that is just a regular scoped section of code. Therefore, on line 48, it detects that it is not immediately following an IF statement, and the error is thrown.

To debug these issues in the future, I recommend deleting lines of code until it works. Then, start adding lines back one at a time until it doesn't work.

[idle dew]

Thank you so much! I will definitely begin to implement this form of proof reading myself in the future.

[idle dew]

Is is this because of the break that I have or would the break not matter? Like if the bracket was on either side of the break

[dapper niche]

the break does not matter. it is purely because you have a statement right after the IF conditional on line 43

[idle dew]

Ok gotcha thank you very much!

[dapper niche]

you can verify this by just deleting line 44, then everything will work

np, this kind of thing will be second nature to you soon 🙂

Hi! today I will enter an exam for python but i did not understand the classes and object oriented programming can anyone have suggestion
?

[brazen walrus]

Classes are blueprints for your objects (similar to real life: like a blueprint of a house). Objects are instances of a class (similar to real life: like actual houses that is already built according to bluebrint).

OOP is just way of programming where you store your data in Classes, and classes methods/functions is basically your logic.

class: House
def open_window():
print("opened")

There are 3 topics in OOP: encapsulation, inheritance and polymorphism
Encapsulation means we don't expose data/logic to other classes unless we need (like private/public functions)
Inheritance means child classes can inherit functionality from parent.

Check here: https://pythonnumericalmethods.berkeley.edu/notebooks/chapter07.03-Inheritance-Encapsulation-and-Polymorphism.html#:~:text=There are three more important,common operation in different ways.

All of those topics apply to any language that can be written in OOP way, including python.

[hardy gate]

thanks really !! can I ask questions about the classes ?

[brazen walrus]

of course, i might not answer immediatly though because my study sessions are 06:30 - 08:30 GMT+2 daily

[hardy gate]

thankss

[dapper niche]

The problem with CS education is very often that they present many concepts and paradigms without being able to teach the student why these paradigms exist in the first place. They might tell you how to use OOP and perhaps a few details on the behaviors, but the student is often unable to get a feel for it since these techniques were created to handle large software products developed by large teams while the student only writes small snippets of code.

What I'm trying to get across here is be aware of the techniques being taught to you while also being aware that you won't have the context for most of it. OOP and other paradigms are all about structuring and organizing code for human beings. It has virtually no functional purpose to a computer at the hardware level. As you progress in your studies, try to keep that in mind -- "how does this organize code or information better for humans?"

[dapper niche]

probably a little more fair and accurate to say "the challenge with CS education"

[thick falcon]

Does anyone have envato Pro? I urgently need to download 2 tempates

[dapper niche]

WEMips is not machine learning. It's a simulator/emulator for the MIPS assembly language. Can't answer your question about hex and ascii because MIPS doesn't do that without someone having written a program to do that. Since we don't have the source code to said program, we can't explain it. As for slicing...have you tried googling it? What questions do you have about it?

[idle dew]

No clues.whats going on?

Nice. uhm let me make more research about them both and get back at you. tysm for clarifying the Mips being assembly message part.

hey does anyone know how to send an email once someone presses a button on a wesbite. im using node.js and js and html ...?

[dapper niche]

if you mean it opens their mail client or web mail client to send the email, then you just create a mail to link or form post. Otherwise, you need to set up a mail server...y'all need to try googling this stuff before asking. It's an important life skill.

[idle dew]

so what have to show by your github link , any contribution

[brazen walrus]

1. In the frontend (html) it is by using "mailto" tag, it will open mail client for the user. But they still has to type everything and send from their mail client like Apple Mail.

2.If you want the backend (server) to send an email, so a user only types something in the webform and backend sends an email, then you will need something like AWS SES (Simple Email Service) on your backend. It will use SMTP protocol under the hood and send email to the emails you whitelisted.

Here how I do it (this is only the final snippet) in my python backend:

    response = config().ses_client.send_email(
        Destination=destination,
        Message=message,
        Source=source,
    )

3. If you want to write your own solution from scratch, it will be a ton of work, and besides, most email providers will put it directly to spam because it is unknown sender from unknown server.

So in the end just go with 1. It is just one-liner.
e.g.
<div><a href="mailto<YOUR EMAIL here"><YOUR EMAIL here></a></div>

        int c = scan.nextInt();

        System.out.println("The equation: (" + a + "x^2) + " + b + "x + " + c + " = 0");

        //find discriminant
        double d = pow(b, 2) - (4 * a * c);

        if(d > 0){
            double x1 = ((-b) + sqrt(d)) / (2 * a);
            double x2 = ((-b) - sqrt(d)) / (2 * a);

            System.out.println("x = " + x1 + ", x = " + x2);
        }
        else if(d == 0){
            double x = (-b) / (2 * a);

            System.out.println("x = " + x);
        }
        else if(d < 0) {
            try {
                double x1 = ((-b) + sqrt(d)) / (2 * a);
                double x2 = ((-b) - sqrt(d)) / (2 * a);

                System.out.println("x = " + x1 + ", x = " + x2);
            } catch (Exception e) {
                System.out.println("NoRealRootsException");
                // it did not show any sign of exception. it shows NaN. how to catch that?
            }
        }
    }
}

I'm struggling with catching exception part.

[fleet pilot]

I have a question, why are trying to get x1 and x2 in d < 0 when you already have it in d > 0?

You didn't get an exception, maybe cause it didn't catch as it already had a value

so maybe use a subclass for getting that exception

Also I would remove the redunant code by:

try {
if (discriminant < 0) {
throw new NoRealRootsException('No equation has no real roots')// NoRealRoots can replace with a subclass of an exception
} else {
double x1 = (-b + sqrt(d)) / (2 * a);
double x2 = (-b - sqrt(d)) / (2 * a);
System.out.println("x = " + x1 + ", x = " + x2);
}
} catch (NoRealRootsException e) {
System.out.println("NoRealRootsException: " + e.getMessage());
}

Maybe this would help

@fleet pilot
can you give me hint on this one:

throw new NoRealRootsException('No equation has no real roots')// NoRealRoots can replace with a subclass of an exception

I'm new to Exception handling

[fleet pilot]

Exception handling where you had it is a great start

however the issue is that your code recognizes NaN as a value

so we can create a subclass of the exception with our own exception

so for the new subclass

class NoRealRootsException extends Exception {
public NoRealRootsException(String message) {
super(message); //superclass constructor
}
}

Once we push it to a superclass, the exception is initialized with the error message

The more I think about it, try to remove getting the x1 and x2 when d < 0

[stiff storm]

here's my modified code.

import java.util.Scanner;
import static java.lang.Math.pow;
import static java.lang.Math.sqrt;

/*
Write a Java program to calculate a quadratic equation. If the equation has no real roots,
the program should catch the NoRealRootsException and print a message to the user.
If the has real roots output within console.
 */
class NoRealRootsException extends Exception {
    public NoRealRootsException(String message) {
        super(message); //superclass constructor
    }
}
public class Main {
    public static void main(String[] args) {
        Scanner scan = new Scanner(System.in);

        //ask user to input the equation
        System.out.println("Standard form of quadratic equation: (ax^2) + bx + c = 0");

        System.out.println("Enter the coefficient 'a': ");
        int a = scan.nextInt();

        System.out.println("Enter the coefficient 'b': ");
        int b = scan.nextInt();

        System.out.println("Enter the coefficient 'c': ");
        int c = scan.nextInt();

        System.out.println("The equation: (" + a + "x^2) + " + b + "x + " + c + " = 0");

        //find discriminant
        double d = pow(b, 2) - (4 * a * c);

        try {
            if (d < 0) {
                throw new NoRealRootsException("No equation has no real roots");// NoRealRoots can replace with a subclass of an exception
            } else {
                double x1 = (-b + sqrt(d)) / (2 * a);
                double x2 = (-b - sqrt(d)) / (2 * a);
                System.out.println("x = " + x1 + ", x = " + x2);
            }
        } catch (NoRealRootsException e) {
            System.out.println("NoRealRootsException: " + e.getMessage());
        }

    }
}

and this is the output:

it suppose to show sth like this right?

[fleet pilot]

For this equation, we know there isn't any real roots. So we are correct there.

So far it looks good, just try with other cases

ensure that it looks good

[stiff storm]

it looks good

thank you for your help @fleet pilot

I'm still trying to wrap my head around java and OOP. This kind of exercise make me quite confused.

[fleet pilot]

@stiff storm I actually think you can do without the exception subclass by just reducing to an Exception

I learned about OOP in java with some websites online

Here's a website that explains some OOPs concept well: https://www.w3schools.com/java/java_oop.asp

[stiff storm]

Thank you for the site. I'll check it out. I'm falling behind in class so I use this website to learn java: https://www.mooc.fi/en/

Thanks again for the help. Tho, i might need you again for my second exercise

i'll try to do it myself first

[fleet pilot]

what gmt are you in

I'm gmt -4, so I'm not able to stay online as long

[stiff storm]

mine is GMT +07:00

[fleet pilot]

If you get stuck, people later on can help you if I don't respond. If not, I can help out if need be later

I'll be signing off

[stiff storm]

sure

thanks again

[fleet pilot]

no problem, happy to be of service
