i've actually had a crippling sore throat and accompanying cough for two days or so of barely being awake or able to sleep

Also, is it satchel style, pods from one of those machines, those beans in a glass jar kind, or something else?

And how the hell do I have 4 followers on Google maps?

Like really, it's Google maps - a platform where you really wouldn't expect followers.

caird coinheringaahing

@lyxal I know this isn't what you mean, but for some reason, I imagine this as 4 people who just follow you around but through Google maps

like, you walk from your flat to a local coffee shop, and Gary in Montana just walks along with you in Google street view

cant think of any more words

I did not solve Semantle #57 in any amount of guesses. My first guess has a similarity of 1.15. My first word in the top 1000 didn't happen because I quit on turn 26.

@AidenChow because I can tell that if I kept on going with semantle, it would become tedious and painful rather than being fun. It just isn't my kind of game it seems

I solved Semantle #57 in 113 guesses. My first guess had a similarity of 16.67. My first word in the top 1000 was at guess #52. My penultimate guess had a similarity of 42.87 (924/1000). semantle.novalis.org

@RadvylfPrograms but who's going to donate if they know your aim isn't directly actionable?

Radvylf Programs

It's directly actionable if we have enough money

We just need to buy a really long bungee cord, a helicopter, and an amateur radio kit

lyxal

But how are you going to get the nukes?

They don't just sell them at Walmart you know.

Radvylf Programs

We don't need to. We bungee down from the helicopter as the president walks by, take the relevant paperwork, and use the radio to send out official orders to launch the nukes.

lyxal

@RadvylfPrograms but why would the president have the relevant paperwork handy?

Radvylf Programs

Nuclear football

The nuclear football (also known as the atomic football, the president's emergency satchel, the Presidential Emergency Satchel, the button, the black box, or just the football) is a briefcase, the contents of which are to be used by the President of the United States to authorize a nuclear attack while away from fixed command centers, such as the White House Situation Room or the Presidential Emergency Operations Center. It functions as a mobile hub in the strategic defense system of the United States. It is held by an aide-de-camp. == Contents == In his 1980 book Breaking Cover, Bill Gulley, the...

Radvylf Programs

High altitude helicopter. Above 60k feet they won't see or hear it.

They'll see you jumping out idiot

You can have your helicopter as high as you want

Radvylf Programs

Pfft, I'd be at terminal velocity

And what if they move out of the way of your reach?

Radvylf Programs

They'd only have a fraction of a second to do so

lyxal

You're going about this all wrong. Physical action has too many risks

Radvylf Programs

I think you overestimate how much time people spend staring at the sky above them.

And how quickly people can react to someone dropping from 100 km/h from directly above them.

lyxal

What if you miss your target?

What if it's a decoy?

That's why I maintain that physical action isn't the right approach

Bureaucracy is the key

Radvylf Programs

The two lock eyes, knowing they only have seconds to be with each other. It's love at first sight. Biden tries to wrap his arms around the mysterious stranger, to be taken back to the helicopter, but before he can manage this the stored mechanical energy in the bungee cord tears the two away from each other. Biden sits down on a bench nearby, knowing they'd never see each other again.

it's a list comprehension

it's more l for l in [2*int(v[1]/2)]

it binds l twice

@UnrelatedString I still don't understand why it iterates over singleton lists

Unrelated String

i don't eithert

lyxal

04:42

@RadvylfPrograms mostly when filtering by a predicate

which is different to the use case here

because something like

(str): lambda: int(
        "".join([char for char in lhs if char in "0123456789"] or "0")
    ),

is more sane than that answer

Unrelated String

because in this case there is no filtering

lyxal

so my best guess is scoping

Radvylf Programs

It seemed to not change anything when I removed it in TIO

yeah it might be like
the way it's evaluated the second `l` might use itself instead of the original
