I think HVAC tech might go to a community college, for instance.

I don't think that's a career that uses an associate's degree - I think it's just a certificate program

not positive, though - it's admittedly outside my area of expertise.

Tig Notaro had a standup special where she performed topless for most of it. After a double mastectomy, she didn't have nipples or breast tissue anymore, so it was fine, apparently! Very, very weird standards.

we'll see who's laughing when the world eventually switches to dozenal (the superior system)

well

only for length rlly

volume is base 2 in imperial units

length is more or less base 12

[static trout]

how

[teal storm]

with base 2 for fractions of an inch

[static trout]

oh imperial

i was thinking of metric

[teal storm]

until you get to thou at which point it's back to decimal

lol

volume being base 2 is very pleasing to me as a CS person tbh

happy today

yes but tomorrow is now today

How to use Stack Overflow:

1. Create your question with your account
2. On a second account give a wrong answer with a confident language
3. Wait for the right answer along with offenses to the wrong answer
   hmm interesting

[thick widget]

"so i have this problem in my code, "

[thick widget]

most of the time you dont need to even ask, someone's already asked your question years ahead of you

[pale mesa]

and then someone will update the answers a few years later, which is a plus

[cursive agate]

unless you are using a new language

or a new library

[sinful frost]

why people do import math , then math.sqrt

isn't it kinda bad to import all math library just for one function

isnt from math import sqrt would be better

[sick olive]

@sinful frost but the whole module runs for both ways

wdym ?

when u import math u have all the names available in the math

u aren't polluting anything unless if u did something from math import *

Good

[pale mesa]

any idea?

this is a past year paper btw, not an exam i am currently sitting for

i cant think of anything else other than insertion into an array being O(n)

[stone gyro]

Consider the complexity of checking whether a name is in it, too

ah, that's an advantage though

they basically want you to make up two ways linked lists are better than arrays, which is a... tall order

[solid prawn]

but finding the spot for inserrtion would still be O(n)

[stone gyro]

O(1) insertion at the front and, uhh, that's it? I can't think of a second advantage

[solid prawn]

yeahh

merging two of them is O(1)

though youd lose sorted order if you did that, which is probably not an advantage in this specific case

they just want one advantage tho

[oak hemlock]

Meow

[solid prawn]

a fine meow to you too

[sick olive]

https://tenor.com/view/dude-im-just-learning-stan-marsh-south-park-s6e3-asspen-gif-22107474

[pale mesa]

any idea on what would part (c) be?

i cant come up with similarities between bst and linkedlist and arrays

[solid prawn]

hmm are BSTs balanced by definition

i forgor

if they are, then you get log(n) search and log(n) insertion

[pale mesa]

i think we can assume they meant a balanced BST because of (d) asking for balacing bst stuff

[pale mesa]

which doesnt seem to have advantages of an array ._.

i guess it comes in the middle?

[solid prawn]

log(n) insertion is an advantage over arrays
log(n) search is an advantage over linked lists

[pale mesa]

ahhh i see, while we are at this, is inserting into a linked list always O(1)?

i heard someone said inserting at the end becomes O(n)

[stone gyro]

Inserting at the end is O(1) if it's a doubly-linked one

it's insertion anywhere in the middle that's O(n) always

[pale mesa]

thats due to the need to traverse the linked list to insert in the middle right?

[plucky onyx]

Connected... Good Day to ALL - I see some talks about optimisation / optimal algorithms ? it's my theme 🙂

[pale mesa]

my lecturer gave me this really confusing notes

which says it is O(1), but i thought it should be O(n)

[stone gyro]

yup

[lean pebble]

Truly optimal algorithm is to post a job titled "Software Engineer" and undercut levels.fyi by 20%

[novel hull]

Depends on whether you take reaching the point in the list as part of the insertion

Because technically, given a doubly-linked list's node, you can insert an item before or after it in O(1)

[pale mesa]

ahh... so traversal itself is O(n), but from then on since u have an determined point, the insertion itself is O(1)?

[novel hull]

Yeah, since it's just a bunch of pointer assignments

Traversing the list is O(n), because you need to find each consecutive element to move further

[pale mesa]

so when comparing time complexity for insertion into an array and a linkedlist, is it safe to say that linkedlist is slightly faster since it is O(1)?

[novel hull]

While with arrays it's just pointer arithmetic, which allows you to, for example, perform binary search

[novel hull]

I assume that's what they want you to answer, yeah

Though I guess it would be worth mentioning in your answer (since it's a freeform question, from what I can see) that insertion is only O(1) if you are already given a node

[plucky onyx]

wrong.... :))) truly optimal algorithm (in this / your) context - to put large SELL order on GOLD and get huge profit tomorrow morning.... right now its possible to trade cryptos.... but don't want to go that way - relaxing till tomorrow :)))))

[stone gyro]

what

[lean pebble]

ah yes increasing number of )

it generates confidence

[novel hull]

Traversing the list to reach a node in the middle will be O(n), though still cheaper than inserting into the middle (or the beginning, which is the worst case scenario) of an array

[novel hull]

assert dominance

press ) repeatedly

[lean pebble]

AssertionError

[pale mesa]

inserting into the middle of an array is O(n) because it has to create a larger block in memory, and copy its contents over iirc?

[novel hull]

!e ```py
dominance = False

assert dominance

[obtuse swallow]

@novel hull :x: Your eval job has completed with return code 1.

001 | Traceback (most recent call last):
002 |   File "<string>", line 3, in <module>
003 | AssertionError

[novel hull]

Yeah, because the contents are contiguous you'll have to copy each shifted element to the right (which is O(n) if you're inserting in the beginning) and potentially reallocate the array if you're out of memory

[quasi cape]

wait , why not inserting at last

[novel hull]

Wym? Inserting into the end of an array, or the end of a doubly-linked list?

[quasi cape]

array

[novel hull]

Inserting at the end of an array is cheap(er) because you don't have to shift any elements

[quasi cape]

ah , so the expensiveness is inversely proportional to the index where we are

[stone gyro]

yeah, n-i operations to insert at i

[plucky onyx]

Pure theorists / TERRORISTS :))))) size of your array / lists in elements ? element type ? hardware you are working on ? :)))

[novel hull]

Yeah, the closer you are to the beginning of the array, the more elements you'll have to shift

Inserting at index 0 will force you to shift the entire array

Given you're using an amortized array, that is. I think if you're reallocating on each insertion there's little additional cost, but you have a bigger problem on your hands

[pale mesa]

aight, imma take some time to digest this. thank you for the help! (i dont want to tag all of yall so i hope yall will see this e.e)

[plucky onyx]

list = [ ['data1', deleted = False], ['data2', deleted = False], ['data3', deleted = False], ]

list[1]['deleted'] = True; ....... ; list[1]['data3']; list[1][deleted] = False;

something that way need to correct this - no insertion - just mark element as deleted, then mark it as undeleted when it gets new (inserted) value and append to end of list if no deleted elements found

[stone gyro]

At the cost of O(n) element access

and in fact, insertion and deletion is still O(n) I believe, since you'll have to find the i-th non-deleted element somehow

[plucky onyx]

yes, to find DELETED !!!!! element just linear search, if deleted elements at begining - faster then O(n) .... if sort this array time to time..... to make them first.... :)))

sort by deletion attribute / flag 🙂

[novel hull]

@pale mesa Here's some images, I hope they are informative more than confusing, hah

[plucky onyx]

How funny theorists / mathematicans are 🙂 - array/list performance depends on low-level software implementations, performance of low level software depends on hardware implementation for example I'm now on Intel Celeron 2 core with 1Mb L2 cache.... only but Xeon processors have about 40Mb cache.... so if your list/array completely resides in this 40Mb cache...... it very very very fast on 2.4GHz 🙂

[novel hull]

:)

[cursive agate]

🤔

[novel hull]

Apparently big-O notation for time complexity doesn't apply to CPU cache

[cursive agate]

🤔

dont mind me im thinking

[plucky onyx]

Why ? I mean difference if your entire datatset is in cache or partially in cache and partially in memory - so you get mem access cycles - wich much slower than data fetched from CPU cache

[plucky onyx]

thats great 🙂 waiting for results :))))

[novel hull]

That reminds me of that one meme about messaging a brand account with "👀" and then responding with "Just lookin'" when they ask if they can help you

[hearty prawn]

that's the tutorial i used lmfao

wanna know something cool?

objects and variables, as far as I know are only free'd once process ends

[stone gyro]

if your list/array completely resides in this 40Mb cache
The O notation is about asymptotic complexity - time as the array size goes to infinity, so this case doesn't matter.

[hearty prawn]

therefore with enough varaibles you can crash your PC

[stone gyro]

Similarly for all the hardware differences. They won't change asymptotic complexity.

[cursive agate]

im just wondering what you mean by your statement

because Big O notation -/-> what cache your CPU has. hmm so yeah it does not matter.

[plucky onyx]

ok, got it, thanks, but mathematicans are still very very funny 🙂 🙂 🙂 is any measure of closiness to infinity ? so how close am I to infinity ? close about 10% to infinity or about 98% I am close to infinity ....:)

[cursive agate]

are u a mathematician?

[plucky onyx]

no I'm pure programmer 🙂

[cursive agate]

yeah

[stone gyro]

meh, I wouldn't say "doesn't promise anything"

making a language was cool and all but tf do i do now

[stone gyro]

I mean, I'm reminded of that GTA 5 online loading bug, which ended up being caused by, apparently, rockstar programmers being hacks who implemented an O(n^2) JSON dict parsing algorithm, and this is used to parse megabytes worth of JSON every launch, which takes minutes. 😔

[plucky onyx]

It's still there. I tried this last time.

Yeah I'm aware

I was wondering if it'd audibly error or just silently noop

I guess the exception would be raised if I didn't use os.system but rather remove

Hm

I don't think there is a way to break out of NsJAIL

Unless you turn it off but for that I need to get it running on my local machine, which didn't work last time I tried.

@obtuse swallow is hosted on Linode servers, maybe they have the locations on their site

[plucky onyx]

so next question to this GREAT thing - if google auth for python preinstalled here or can be installed - than I can read here file from my google drive an process it - and show my processed data to community and allow to play with it

[sick olive]

but it's read only, so nothing can be done

!e
import datetime
print(datetime.datetime.tzinfo())

[plucky onyx]

my drive is read / write - so all changes can be saved back to my google drive shared file

[sick olive]

!e

[plucky onyx]

i can make shared folder on my google drive and we can play with files there from right here

[sick olive]

!e

[sick olive]

yea

but again I don't think u can access system cmds

If you want to test out the bot, may I suggest using #bot-commands instead of ot0?

does that work

zip(*item) transposes the iterable

thoughts on cash-app vs paypal?

[oak hemlock]

in what regard?

[sick olive]

which is better, not only in pros and cons but with personal experiences

[pale mesa]

not american enough to try out cash app

[sick olive]

same

[pale mesa]

but paypal works for me. the transaction fees are abit irritating sometimes but i never had issues with it

[sick olive]

nah i've hated paypal recently, they block your account for literally anything

i have money locked in there since march

[oak hemlock]

probably definitely PayPal

I can't imagine CashApp being better in many regards tbh

It's a lot harder to get away with things on PayPal, plus it's used by a lot more online retailers

[pale mesa]

cashapp feels more casual to me

[sick olive]

surprised no one has created a payment app which solves the problems paypal has

[oak hemlock]

and what's that?

[sick olive]

money transfers

[oak hemlock]

uh

what are you using PayPal for if not to transfer money?

[sick olive]

i mean they make money transfers so painful

[oak hemlock]

hm... not in my experience

[pale mesa]

ey? i thought u just enter the email and then its one click away

[oak hemlock]

yeah lol

[sick olive]

yeah i'm just waiting for strike to come to the uk

[clear root]

tbh, everytime I wanted to give a friend money, I just did it through a bank

or even online retail

[neat glen]

it's called future

[oak hemlock]

I've used many different things in the past lol

[pale mesa]

if u want really safe ways just do wire transfers haha

[oak hemlock]

PayPal, CashApp, Venmo, crypto

unfortunately everyone just uses their own things

[sick olive]

i would use crypto for international payments. since it's not managed by governments or anything and it's an online currency, there's no fees

[pale mesa]

my country is real small and our banks have their own standardized payment protocol

[neat glen]

just use cash ._.

[pale mesa]

so its easy to transfer money directly from banks

[clear root]

there are fees for crypto

[sick olive]

not with strike

[vast marlin]

type help in #help-grapes

[clear root]

they are just smaller than alternatives for international transfers

[deep heath]

'protects'? Lol, no. Because it has it's own bubble and its worts is based solely on demand

[sick olive]

bitcoin lightning network resolves those issues

[still pike]

huh...?

[deep heath]

Gold is inflation-proof. Swiss Frank used to be inflation-proof because it used to be covered with gold

[sick olive]

yeah i should've worded that better

[deep heath]

Crypto is basically gambling that the hype will continue and you can sell your coins late at the higher price (because demand)

[clear root]

at the same time, buying voting rights for a financial system seems a bit dystopian

[sick olive]

best to use bitcoin because of it's lightning network

[deep heath]

Didn't Revolut market themself as easy payment and transfer in any currency? They were quite loud a few months back, now I don't really see their ads

And I'm salty at how Revolut's recruiter just ghosted me when I asked for its antidiscrimination policies. They just said 'we have it' but when I asked some detailed questions, I got ghosted. And when I finally said after a month or two that the silence speaks more about their real inclusivity than their declarations, I just got told the position is closed now. Not even sorry, if I recall correctly

[sick olive]

can't believe revolut charges you just to make an atm withdrawal

yeah we're definitely moving towards a cashless economy

especially since covid

[deep heath]

It's actually common in banks to do that...?

[sick olive]

^

[deep heath]

And since Revolut doesn't have their own ATMs, then they don't really have any way of providing withdrawals without any fees

It depends. My bank makes my card and all withdrawals free if I fulfill some stuff.
Some banks have fees for ATMs belonging to different organisations

[sick olive]

which country do you live in, if you don't mind me asking?

[deep heath]

And every bank has a fee for withdrawal in other countries - and Revolut's cards aren't really based in any country, so it's just logical they keep their money virtual

[eternal trail]

Some banks have fees for ATMs belonging to different organisations
same here, but only if you withdraw over x times a day or something

I think it's 2 withdrawals per day

[deep heath]

Poland. And Bank Millennium (which is originally from Portugal, as Millennium BCP or just BCP)

[sick olive]

i'm switching to them from halifax soon

monzo has to have the worst security i've seen 😂

[thick widget]

i hold it pretty much everyday

[neat glen]

why is mspaint lagging on this size, is it too large?

[deep heath]

In my case it's about those requirements that also make the card free. For student/young adult account (which I still have, I guess they will convert me next year or they forgot? XD) it's about card usage only (card-present transaction druign a month). For full account it's also about earning (getting inbound transfers) of x amount during a month. So I don't even remember what the fees are, at all XD

I also decided to keep my business account there as I formally need one and there are no fees when you have personal with them as well

Although I don't keep a card for it

[thick widget]

id reckon it is

[deep heath]

Nfc payment from my bank app + BLIK when I can't be arsed to log in on bank webpage to confirm online payment or type card info because we 3DSecure and I'd need to confirm on the app anyway

https://en.m.wikipedia.org/wiki/Blik

Blik also allows for making cardless withdrawals, so I don't carry a card with me at all

[sick olive]

how does that work? do you get a code or something that you can scan at an atm?

[deep heath]

6-digit code, 2 minute lifespan. You type it in. Then I guess the ATM/blik website (for online payments, I use it for shipping all the time) makes some request and checks for active blik codes (I guess it must be centralised so they know which bank to ask? or if I select my bank as payment option, I get blik or normal login, so they just check their own)... Then bank app prompts you to confirm payment (with info how much, to whom, and device details like OS and browser). Type in your PIN and you're done

Blik also allows for easy transfers to phone numbers (you register in your bank app your phone number and it's used as shorthand for your account number)

[sick olive]

oh alright

[static trout]

we have something like that too
a lot of them actually
Paytm, Google Pay, etc etc (there are a lot)
the only reason they can coexist is because UPI exists - it allows transactions from any app - that's 1 thing that the government did nicely

except it doesnt withdraw from your account

it's like a seperate mini-bank you charge with money at your convenience and you can make payments from there

[deep heath]

Google Pay is using your card linked to Google to pay for stuff, including NFC payments. I use it for uber

While blik is integrated by banks themselves

And not a separate account to prepaid or linked service that charges your card

Blik was launched in February 2015 by Polski Standard Płatności, an alliance of six Polish banks,[4] itself a member of the European Mobile Payment Systems Association. The number of participating banks has grown since. Blik had 7 million users and processed 424 million transactions in 2020.[5]

[deep heath]

My partner recently became annoyed because they have their card saved in eg train ticket system... But now the train system implements 3DSecure and they would need to log in to the bank anyway (log in + text message code) to confirm the card payment. And I just use blik XD

🤷‍♂️

[static trout]

struct ColorCode(u8);

impl ColorCode {
    fn new(foreground: Color, background: Color) -> ColorCode {
        ColorCode((background as u8) << 4 | (foreground as u8))
    }
}

(background as u8) << 4 | (foreground as u8) what does this statement do? thanks

[dusty aspen]

eww imagine not using named struct fields

[tepid echo]

kinda confusing yea

[onyx ice]

Hmmm interesting spelling you have there

[static trout]

HEY I TOOK IT FROM A TUTORIAL OK

rest assured anything going in my code will be "colour"ed.

[dusty aspen]

| is or, as u8 converts whatever background and foreground are to u8 (since they're operating as c-like enums I think), and I have no idea what << is

[tepid echo]

@onyx ice this name is great

[static trout]

yup, the tutorial does mention a c-style enum

[tepid echo]

are you bald bearded btw

[dusty aspen]

Here's an example of C-like enums (and it uses color, not colour!!!) https://doc.rust-lang.org/rust-by-example/custom_types/enum/c_like.html

[onyx ice]

Thanks! I am bald, bearded and currently proofing some bread. Now I just need to sing about it like a bard

[tepid echo]

lol ok

[novel hull]

<< is bitshift to the left, I assume

Which is basically equal to multiplying by 2 ** n

[static trout]

https://os.phil-opp.com/vga-text-mode/
just take a look at this link

[dusty aspen]

Yeah you're right https://doc.rust-lang.org/reference/tokens.html#punctuation

[tepid echo]

good to know!

I've never really understand bit manipulations

[novel hull]

Bitshifting to the right is the same, except you're dividing and rounding down

[dusty aspen]

don't we all, don't we all

[novel hull]

They're pretty simple actually

[static trout]

aaaaaa i get it now

[tepid echo]

I mean, I've never tried to understand them lol

didn't need them

[dusty aspen]

it's great yeah

[tepid echo]

they're fast aren't they

[novel hull]

& is masking, you're checking if something is present
| is inserting, you're forcing a bit to be 1
^ is removing, you're forcing a bit to be 0

You can store a lot more info using integer masks

[static trout]

so we need to write 1 byte (8 bits)
so we are shifting the background u8 to the side and adding the foreground u8 using a insert

i got it thank you
i just needed to know that's a bitshift

[tepid echo]

    #include <iostream>
     
    using namespace std;
     
    int main() {
      string a, b;
      cin >> a >> b;
      int sum1=0, sum2=0;
      for(int i = 0; i < a.size(); i++) {
        sum1 += (int)tolower(a[i], locale());
        sum2 += (int)tolower(b[i], locale());
      }
      if(sum1 > sum2)
        cout << 1;
      else if(sum1 == sum2)
        cout << 0;
      else
        cout << -1;
    }``` why tf this code failed at test 5 :/

[serene dagger]

yooo drop it on SoundCloud

[tepid echo]

great

[obtuse swallow]

@sick olive :white_check_mark: Your eval job has completed with return code 0.

[static trout]

ColorCode((background as u8) << 4 | (foreground as u8))

one question about this

[tepid echo]

so what's the point of it

[static trout]

because ColorCode is a u8

and the inputs are u8

wont it overflow?

aboo will say: Hi :D

[dusty aspen]

ColorCode isn't a u8, it's being used as a C-style enum

[ocean walrus]

Bit shifting left is sort of like multiplying a value by two, or multiples of two

[static trout]

struct ColorCode(u8);

[unreal zenith]

should i use pycharm or vscode?

[static trout]

isnt it based on u8 anyway

[tepid echo]

hm

[tepid echo]

emacs

[ocean walrus]

Depends

What do you prefer? Both will provide you great experiences

[dusty aspen]

... nvm, it's a struct with an u8 value, oops

[static trout]

that's what im telling

[unreal zenith]

i like both, I like having liveshare and github closely integrated which is why I use vscode, also it's pretty light on resources

[static trout]

wont it overflow

[unreal zenith]

but also pycharm installs every package for a project into the project folder so it can run everywhere which I like

[onyx ice]

I like VS Code (and Vim for quick things)

[unreal zenith]

vim scares me

[novel hull]

I'm pycharm gang

[onyx ice]

Nah, just get through vim tutor once and use it a few times, should be good to go from there

[novel hull]

Though VSC is pretty good also, I use it for go

[unreal zenith]

graphic design is my passion

[dusty aspen]

See this https://doc.rust-lang.org/book/ch03-02-data-types.html#integer-overflow

In debug mode, it overflows. In release mode, it does two complement wrapping.

[sick olive]

its that simple?

[static trout]

oh i see

wait nvm i just realized overflow isnt a problem

because the Color enum has values only upto 15

in other words, just a u4

[novel hull]

And two of those fit nicely into a u8

[static trout]

yes

"Now it appears the backlash was so extreme the tech giant decided to quietly scrap the new move just days after it announced the change. "

[novel hull]

Who could've seen that coming

[solid prawn]

i didnt

didnt think they would listen to community feedback that is

[sinful lark]

yeah i was pretty certain they were not gonna 180 on this

[static trout]

Since the field ordering in default structs is undefined in Rust, we need the repr(C) attribute. It guarantees that the struct's fields are laid out exactly like in a C struct and thus guarantees the correct field ordering.
would someone please explain what difference does it make

[pseudo pivot]

guys what would be better to learn css (advanced) or typescript? 🤣

[narrow prawn]

can someone help me out, im tryna revise for a paper. i forgot what computational thinking is

[dusty aspen]

Depends. Do you want to learn how to style things better or to have a more pleasant experience with JavaScript?

also, what constitutes as advanced CSS? The syntax of CSS is rather simple, and memorizing all the possible properties is a lost cause.

[pseudo pivot]

ofc will focus on styling and transition

[narrow prawn]

css is actually alot better for programing game mechanics, but like dawn said above time with java is more on the side of typescript

really depends on the purpose

[dusty aspen]

Uhh, what does CSS have to do with mechanics? It's for styling.

[pseudo pivot]

i know java and js atleast as much as i need them

just a bit weak in css

[narrow prawn]

then go for typescript, since u know alot abt java its going to be alot easier for u 2 learn

[dusty aspen]

Uh, typescript has nothing to do with java, besides the fact that they're both statically typed

[pseudo pivot]

^

[narrow prawn]

just the generic components, like abstraction and decomposition

[sick olive]

has anyone here heard of web3 before? if so, do you think its a good or bad idea. do not search it up.

[hollow holly]

web3io?

The smart contracts thing?

[sick olive]

im trying to get as close to an objective view on cryptocurrencys and stuff as possible.

to do so im trying to see how many people even know what web3 is, and of those who do, how many think its good and how many think its bad.

[cursive agate]

advance css is becoming a god in memorization

[sinful lark]

anyone have a ELI5 explanation for race condition and data race?

[magic tendon]

two pieces of code tries to modify the same data at the same time, causing the state to not make any sense anymore

for example, you have a count.txt file that is incremented by a script after ten seconds for some reason

[dusty aspen]

it can also happen with one piece reading and another writing at the same time, right? Or is that fine?

[tepid echo]

do you guys directly search on stackoverflow or you just google it

[dusty aspen]

google, always

[sinful lark]

I see.. So is that a race condition?

[tepid echo]

i think verbose directly search on stackoverflow

iirc

[pliant canyon]

ay but if two pieces of code read data it should be fine ri?

[magic tendon]

with open("count.txt") as f:
    count = f.read()

time.sleep(10)

with open("count.txt", "w") as f:
    count = f.write(count + 1)

If I launch two of those at a 20s interval, it should work fine, right?

[sinful lark]

yeah

[magic tendon]

yep, there are all kind of different problems that lead to a race condition

[hollow holly]

A real-life example of a data race, kind of (credit to gobble for this) ,would be deja-vu

your brain is trying to read memories while also writing, hence why you feel like you've been there before

[deep heath]

Reading doesn't change the state, content, so it's safe

[pliant canyon]

nice

[magic tendon]

now what if I launch two of those at a 1s interval?

[teal storm]

well the C compiler expects the fields in a struct to be laid out in a certain way (namely, in the order in which they are defined, + alignment) so if they aren't laid out like that then the C code and the Rust code will be accessing the wrong data
like for example let's say i had a struct like this:

struct Thing {
    uint64_t a;
    uint16_t b;
}

now the C compiler will assume that a comes before b but then maybe the rust compiler puts b before a, and then in your rust code you assign a = 1 b = 0 and then you pass it to the c code but the C code expects a to be before b so it reads b = 1 a = 0

[sinful lark]

hmm... um would it still be okay since its on a single thread?

[magic tendon]

nah, you launch that script at the same time, and you assume your OS is smart enough to have multitasking

[sinful lark]

so what would happen during a 1s interval exactly?

[magic tendon]

lemme just make you a timeline

[sinful lark]

alright

[teal storm]

web3 is cryptobros putting blockchain in places where it makes no sense

[sick olive]

"cryptocurrency is a solution looking for a problem"
thats the best thing ive heard on my research honestly

[teal storm]

no reading and writing at the same time is a race condition still because the data that is read is fucked up

[dusty aspen]

nicky replied to a message about 2 readings, no writes

[deep heath]

[teal storm]

yeah that's more or less accurate
and to the extent that i am interested in crypto, im only interested in the eco-friendly non-gpu-market-hyperinflating variety like nano, bitcoin is a no

[teal storm]

ah i misread

[teal storm]

i thought it was a reply to this

brain moment

[deep heath]

Well, without context (with missing reply) my message is wrong, I don't blame you :)

[sick olive]

now even if cryptocurrency works as solution to problems like big tech having all our data, its more of a trade the anything. in return we get free services, youtube, google docs, practically unlimited storage. cryptocurrency doesnt give any benefits in return. and, big tech are beginning to invest in crypto because of web3/metaverse. the best way of making money off that is nfts. its no coincidence that discord is beginning to implement nfts. theyr'e not going to sell our data. instead, they're now going to discretely make everything pay to win. we've literally just replaced one trade off with another.

[magic tendon]

@sinful lark

[static trout]

ah i see

thank you!

[magic tendon]

they both read n and write n + 1, because the first process didn't have time to write to the file before the second process could read it

so despite launching two processes, the file has only been incremented by 1

[sinful lark]

ahh i see

[deep heath]

A note: it doesn't even need sleep, even normal break between two operations can result in something doing something else in the middle

[teal storm]

NFT is a pyramid scheme

[magic tendon]

yup yup

[sinful lark]

so what is the best way to avoid this race condition

[teal storm]

mutex

how do mutex work

mutex or use rust

or both uwu

[magic tendon]

some form of locking

[deep heath]

Atomic operations in lower level

[sinful lark]

oh lol

[teal storm]

which ones

[sinful lark]

so this mutex will lock the portion of the thread until the first task finishes?

[deep heath]

C has atomic ops. I remmeber using it years ago

[sinful lark]

or do they work in parallel

[teal storm]

i was thinking abt how to do it and i had an idea to have like a boolean flag that says if it's locked but writing to that boolean flag is not an atomic operation

[deep heath]

It's literally like a flag. But its check/writing True and False (lock and unlock) are atomic and don't have this downtime where something else can happen

[teal storm]

or more specifically, checking it and then writing to it is not an atomic operation

[sinful lark]

ahh okay i see

[deep heath]

https://en.cppreference.com/w/cpp/atomic/atomic idk if I did it in C or C++ those years ago but here's cpp's atomic

[sinful lark]

thank you

cpp standard library so big, ive never even heard of this lol

[sick olive]

imagine using libraries or modules in anything or for anything smh

[deep heath]

Mutex libs already implement it, atomic is useful to understand stuff but using it is annoying
https://en.cppreference.com/w/cpp/thread/mutex

[sinful lark]

so what is the difference between atomic vs mutex?

[sick olive]

seriously i try to avoid modules 99% of the time

[deep heath]

lock in mutex lib is literally 'wait here until you can lock', try_lock is one check only

There are also semaphores which are kinda like... Not flag mutex but value mutex. They allow for a set number of locks at the same time

[sinful lark]

so will mutex lock slow down whatever you are doing?

[deep heath]

Well, it sleeps until you can acquire the lock

[sinful lark]

ah, and as for an atomic operation, there is no locking involved

[deep heath]

Atomic only means that something is one operation. In case of mutex it's checking state of mutex and changing the state. So there's no chance that someone else will do anything in this sleep/pause part (Ak's diagram, after which I said the sleep can also be just normal time between two operations) @sinful lark

Race condition can also block you if you do more than one mutex at once (eg one for each resource)
Because let's say one threat locks mutex A and then mutex B. And the other tries them as well... but in opposite order.
And it can happen that thread1 locks A, thread2 locks B... And they wait for each other's release which doesn't happen

That's why you should always lock from the same 'direction' so you don't lock yourself out

[sinful lark]

oh interesting.. thank you for the explanation. I am gonna play around with std::mutex and atomic now.

also thanks @magic tendon for the detailed timeline

[deep heath]

Lol, staff at the cat cafe realised the tip box has money. I overheard one member telling the other "I got a heart attack" XD

[sinful lark]

no thanks im already unintelligible enough

[sinful lark]

the area of new york city i live in is literally Dhaka 2.0 🤣

too crowded and i dont like it, thats why im moving out after next semester

[safe ravine]

My parents would only speak Bengali to me before I started school

When I did my mum wanted to hear me speaking English and I was shy to speak it then gradually I did and it turned into me speaking only english.

[pseudo pivot]

Ah Bengali nice

I am one too

[sinful lark]

it was the opposite for me lol, they were worried i was gonna forget bangla lmao

[teal storm]

i still don't understand cuz checking the state of the lock and then changing it is fundamentally not an atomic operation

[oak hemlock]

I would guess the answer to this is yes

[pliant canyon]

handle that player movement 😩

[oak hemlock]

tbh I have yet to conquer C# naming schemes

everything is just PascalCase

[pliant canyon]

yes

[sinful lark]

thisThat this_that ThisThat

[oak hemlock]

someone thought that was a good idea apparently

[pliant canyon]

it does look wird

[sinful lark]

i prefer snake case for everything i use. regardless of language. Bad practice most likely

[oak hemlock]

yeah

I'm trying to "fit in" but it feels so cursed

[sinful lark]

yeah i feel u lol

[oak hemlock]

classes are PascalCase, methods are PascalCase, functions... aren't?

[sinful lark]

anyways i didnt know c# naming convention was pascal case. always though it was camel case

[oak hemlock]

maybe I'm crazy, actually

functions might be PascalCase

[pliant canyon]

there are no functions

[oak hemlock]

then what do you call methods that aren't bound to a class?

[pliant canyon]

non existent

[sinful lark]

isnt procedure also a function

[oak hemlock]

Rider calls them "Local functions"

[sinful lark]

class functions = methods and anything outside of a class i call them functions

[sick olive]

a procedure just performs a task, a function does a task then returns a value

[pliant canyon]

yea but u cant have functions outside a class in c#

[oak hemlock]

This isn't true anymore

[sick olive]

i know a kid who uses scratch. their naming scheme was essentially iphone case. Lower case first letter of the first word, and then uppercase first letter of the second word, then lowercase.

[pliant canyon]

c# 8?

[sick olive]

tIsiPhoneCase

[oak hemlock]

idk the specifics tbh

[pliant canyon]

the one where u dont need public static void main(string[] args) {}

[sinful lark]

yup. i forgot where i saw it before... Maybe when i was playing around with assembly i heard it

[sinful lark]

Procedures or subroutines are very important in assembly language, as the assembly language programs tend to be large in size. Procedures are identified by a name. Following this name, the body of the procedure is described which performs a well-defined job. End of the procedure is indicated by a return statement.

[pliant canyon]

yea that

thats just a convenience thing

how far can u go without making a program class

with a main method

[oak hemlock]

Rider calls it a local function, though

[tepid echo]

I like the theme

[pliant canyon]

damn rider

i guess rider is right

[tepid echo]

but tell me, why java 🥲

[oak hemlock]

it's just Material Dracula

[sinful lark]

what would be the opposite of local function
