that just returns that flag

I confused with FusedStream
FusedStream has a method that says if it's done
This trait should be implemented by all iterators that behave this way
Iterator::fuse has a specialisation for FusedStreams

implement Clone

let token = self.lexer.lex_token();
if token.kind == TokenKind::EOF {
self.exhausted = true;

Some(token)

else {
if internet() == true:
try:
translate msg

Thank you very much.

So, not concurrent?

But you're saying it's on a single OS thread.
Doesn't concurrent basically need two threads and would switch back and forth real fast?

concurrency:

B starts
A finishes
B finishes
vocal basin
asyncio achieves that without OS threads

Two threads.
tasks not threads

asyncio allows tasks be executed non-sequentially within a thread

yeah lol
vocal basin
the proper is:
A starts
B starts
A finishes
vocal basin
the proper is:
A starts
B starts
A finishes
(this sequence is enough to demonstrate concurrency)
frozen owl
and you'll have to keep polling until b finishes?
frozen owl
since technically an async func would return a future on its own?
vocal basin
wait, no, actually B being able to finish after A finishes there is somewhat important
so that one is not strictly contained within the other
because
AAAAAAAAAAA

there B might be just a subcall of A

@vocal basin is math.ceil or __ceil__ better? Or are they the same?

Doesn't matter, you joined barely 3 days ago

it has been 3 days
primal shadow

stoic chasm
and ive been here 3 days
primal shadow
nope
stoic chasm
like there are a span of 3 days ive been here
primal shadow
you joined on wednesday

ive also been here the last 3 days

3 days there means 72 hours

You joined 2 days ago, on the 28th
today is the 30th
why is this so complicated?
you joiend 2 days ago
stoic chasm
ive been here for several hundred hours
primal shadow
that's great
stoic chasm
why does that matter
stoic chasm
yea i dont have any clue what that has to do with it
primal shadow
it checks when you joined, has it been 72 hours? no? not 3 days
really simple stuff

go join your country's discord where it is relaxed if we're too not relaxed here
there's rules for a reason

take more than 3 days time and relax as much as you want

keeps VC happy
stoic chasm
no it keeps it an in-group
primal shadow
lol

primal shadow
because joining is such a... tedious exclusive tasak
primal shadow
that is comical, an in group? Yes, the people who have spent a few days in teh server and sent messages
so uh... people who want to spend time here get to speak
stoic chasm
I spent several months and 2000+ msgs
primal shadow
not really an 'in-group' by most definitions since it's so easy to get in
cool ,then you elft
stoic chasm
why is leaving to be punished
primal shadow
you've got the message count
stoic chasm
i also have the time
vocal basin
oh wait I remember who this is
what a 🦜 reference
primal shadow
if I burn my passport, why can't I have a new one immediately?
primal shadow
not consecutive though
stoic chasm
the ship it as soon as its lost
verbal zenith
I remember them too
primal shadow
the ship it as soon as its lost
No, you need to file paperwork, wait for things
stoic chasm
i have done it
primal shadow
nothing is immediate
that's great, but you elft
lost your permission, soon you can get it back
stoic chasm
yes usually 2-3 days
stoic chasm
i know this because my passport was destroyed and i got a new one the next monday
primal shadow
that's how long you have to wait after joining this server before yo uapss the time requirement to get VC
vocal basin
@whole bear tl;dr: this person likes to argue dumb stuff without any backing reasoning, as many people have had to deal with previously
verbal zenith
Question, are you arguing with us because you believe we will issue you permissions to talk, or because the principle annoys you?
vocal basin
since you asked for explanation
stoic chasm
you lied
thats it

why allow for a broken thing

What the actual fuck? 72 consecutive hours from joining must be had

why is that so hard to comprehend?

why am i not to be taken seriously
imagine being a troll and begging for attention at the same time

You must be in the discord for more than 3 days from your most recent join date. That's the only fact we need, what else do you want?

how do you get it to do that

How do you get it to not do that?

you have compact mode on

My best guess is you changed a setting
I did not
Discord has always shown members in role colors for me across all my devices
stoic chasm
it does it on my phone

i want to be able to understand why the rules exist as they do
Rules exist as a way to establish order, fairness, and predictability within societies, organizations, and various systems. They are shaped by a combination of factors, including human behavior, cultural norms, historical precedents, ethical considerations, and practical needs. Here are some reasons why rules exist the way they do:
1. **Maintaining Order:** Rules help prevent chaos by setting clear expectations for behavior, which is essential for any group or society to function smoothly. Without rules, there would be no agreed-upon standards, leading to conflict and disorder.
2. **Promoting Fairness and Justice:** Rules aim to ensure that everyone is treated equally and fairly. They are designed to prevent discrimination, favoritism, and unjust practices, creating a level playing field for all.
3. **Protecting Rights and Safety:** Many rules are established to protect the rights, safety, and well-being of individuals and communities. For example, traffic laws exist to prevent accidents and injuries, while laws against theft protect property rights.
4. **Reflecting Cultural and Ethical Values:** Rules often reflect the moral and ethical beliefs of a society or organization. They encode what is considered right and wrong, acceptable and unacceptable, based on shared values.
5. **Ensuring Functionality and Efficiency:** In organizations and systems, rules are necessary to ensure that processes run efficiently and effectively. For instance, rules in a workplace might govern how tasks are completed or how decisions are made to maximize productivity.
6. **Encouraging Accountability:** Rules establish clear responsibilities and consequences, holding individuals and entities accountable for their actions. This helps in preventing abuse of power and ensuring that people adhere to agreed-upon standards.
7. **Adapting to Change:** Rules can evolve over time to address new challenges, technologies, and social changes. This adaptability helps societies and organizations remain relevant and effective in a changing world.
8. **Providing Predictability:** By setting expectations, rules create a predictable environment where people know what to expect and how to behave, reducing uncertainty and confusion.
Rules are not static; they evolve in response to changing circumstances, challenges, and collective learning, ensuring that they remain relevant and effective.
Rules provide structure and order in society. They help establish clear expectations for behavior and promote fairness and safety for everyone.

Added in version 3.4.
Source code: Lib/pathlib.py
This module offers classes representing filesystem paths with semantics appropriate for different operating systems. Path classes are divided between pure paths, which provide purely computational operations without I/O, and concrete paths, which inherit from pure paths but also provide I/O operations.
If you’ve never used this module before or just aren’t sure which class is right for your task, Path is most likely what you need. It instantiates a concrete path for the platform the code is running on.
Pure paths are useful in some special cases; for example:
primal shadow
wise cargoBOT
Lib/pathlib.py lines 343 to 351
def __new__(cls, *args, **kwargs):
"""Construct a PurePath from one or several strings and or existing
PurePath objects. The strings and path objects are combined so as
to yield a canonicalized path, which is incorporated into the
new PurePath object.
"""
if cls is PurePath:
cls = PureWindowsPath if os.name == 'nt' else PurePosixPath
return object.__new__(cls)```note: __init__ is called even if you return an object which has been __init__ed before
primal shadow

vocal basin
AI can solve it in quite compact manner

sure it will have questionable semantics
but it will work and be safe from the outside

and unlike C++, there are no hundreds of inadequate weird edge cases like std::vector specialisation
