here's some of Matt Parker's terrible python code (but golfed to save me typing): b = [x for x in a]

which I believe can be written b = a[:]

@Neil can you believe ive written that code myself

i wrote it to convert a generator to a list

Generators 🤣

Love those and how they don't share any methods or types with lists

Meaning if you want to use both generators and lists in a project in the same way, you have to write a wrapper class

Great fun

TREE(n) asks for largest possible length of a sequence under a given condition, and increases fast but still computable. Any such function that is finite but uncomputable? Try be not so "trivial"(IDK how to define trivial)

Do you think they'll:

A) Never get back to me
B) Quote me an absurdly high price compared to resellers

(none of the resellers have the 5G option)

I don't even really need mobile broadband on a laptop, the idea of it is just so cool that I can't resist it if the laptop supports it as a config option

I wouldn't be surprised if I could add in the 5G later somehow, maybe it's M.2, but I can find literally no info online

Actually yeah I'd be shocked if it wasn't an M.2 module

which I could totally add myself

Unrelated String

3:15 PM

yeahh

rydwolf

you know something I realized

when you use SSH, and the latency feels almost nonexistent, that's a packet going back and forth every keystroke. there's no reason the web can't be that fast

and if you navigate to something like motherfucking website that's just plain HTML, it is that fast

like you click the google result and it's instantaenous

Ginger

I resent the implication that websites which aren't plain HTML are necessarily slow :p

~~I think you're biased by poorly designed college websites~~

rydwolf

No, I just mean that that's the absolute baseline for the fastest a website can be, all else being equal

CSS and well-written JS won't slow down the first paint that much

Ginger

ah

rydwolf

but modern frameworks, fonts, unnecessary AJAX, all that stuff definitely can

oh and ads and analytics

Ginger

@rydwolf Yeah ads is the main one

Did you see that viral Twitter story (I saw it copied to Tumblr) where someone set up a pi-hole to block all ads network-wide and suddenly everything loaded faster?

rydwolf

yeah

It does read as kinda overexaggerated though

...would anyone happen to know of a Firefox extension that does nothing but make visited links globally not change color? No idea how to search for one

Trying to combat my reflex to do most of my browsing in private windows since, surprise surprise, browsing history can be helpful, but having these hideous purple links peppered all over Wikipedia is making it a little hard

rydwolf

You could make a userstyle that does something like this:

a:visited {
    color: unset;
}

idk if that's how unset works

Unrelated String

I am finding some extensions that let you change the visited-link color, but no evidence that they can uniformly change them to the same color as unvisited links regardless of how those are styled

Ooooh, thanks

RubenVerg

@rydwolf no, that makes it the default text color

Unrelated String

So I just make a userscript that injects that into the CSS of everything?

Oh :(

RubenVerg

i don't think there's a way to say "color if it were to be not visited" in css

rydwolf

4:06 PM

ah, it seems to do tgat yeah

Unrelated String

So you'd have to programmatically edit the existing styles for it I suppose

rydwolf

Is it specifically wikipedia you care about, or also other sites?

Unrelated String

Everywhere

rydwolf

An extension like that might exist for security reasons

Unrelated String

It definitely bugs me the worst on Wikipedia though so just having something scoped to there to turn the purple links blue ought to be fine

rydwolf

4:08 PM

Side-channel attacks that read browser history using :visited styling are pretty common

Unrelated String

Ahahahaha

rydwolf

They prevent any obvious means of doing it by limiting the styling changes to color and text-decoration and stuff, but much subtler things like timing attacks have been found

Unrelated String

And the closest I've found from that are... an extension that selectively nukes individual URLs from your history, and an extension that globally enables visited link coloring on sites that don't have it

🙃

rydwolf

You could maybe do something super janky with ::after?

using JS for this seems kinda nuclear but it might be the only option

Maybe iterating through document.styleSheets and nuking any blocks that use :visited?

Not sure if that's something possible or not

Unrelated String

Less nuclear than a non-JS-based extension of some sort :P

Ooh yeah that could be possible

wait fuck even the actual extension in Firefox are in JS

😭

rydwolf

4:18 PM

Looks like it is actually possible to use deleteRule to delete a styling rule, and selectorText with a regex to test for :visited

Unrelated String

That sounds promising

rydwolf

You'd just have to somehow listen for new stylesheets, maybe with a mutation observer on head

Unrelated String

D:

rydwolf

Not sure if that captures every method of injecting stylesheets tho

Unrelated String

And I assume the same dynamic content caveat would apply to, like, trying to just cover everything with rules capturing every link in the most specific terms possible

rydwolf

4:21 PM

Wait you mean like, just specifying your own link styles to cover up any existing ones?

That would work if you used !important, since .style styles are the only things which override it, and can't depend on the :visited status

But making the override link color work for different background colors would be difficult

RubenVerg

i'm confused, does layout.css.visited_links_enabled in about:config not work?

i'm guessing you already tried because it's the first result

Unrelated String

Yeah, my idea was to still respect however unvisited links are styled

@RubenVerg Ooooooooh that sounds very promising LMAO

Did not occur to me that there would just be a straight up setting for it, even though I assume I'm not the only one to find those bothersome

rydwolf

I'd imagine the security issues is another big reason the setting exists

RubenVerg

did you not write "firefox disable visited link color" in your favorite search engine

Unrelated String

IT WORKS

Thank you so much

@RubenVerg I searched the addons :P

Did consider searching "how to" after the addons didn't turn up anything but that was still only on the premise that I would get better addon results

@rydwolf IIRC most browsers will ignore :visited styles when using e.g. getcomputedstyle, but there's probably ways around it

rydwolf

Unless something goes terribly wrong, like a side channel in SVG rendering, there are not ways around it

It's a very known vector for attacks so plenty of attention is paid to preventing it being exploited

emanresu A

Ah okayy

@rydwolf What kind of attacks?

Heard there were shots fired a few hours ago but only recently that they confirmed it was an actual assassination attempt

But third time's the charm is all I'm saying

Bbrk24

Honestly I'd feel a lot worse about a successful assassination if it occurred before the election

because then the republicans can use the martyr argument

rydwolf

That's true, I think Trump is probably a bit of a Hitler right now, in the sense that (well in addition to all the other senses) he's more damaging to his cause to keep alive than dead

I think this is a talking point that gets a little overexaggerated, but the media and the left are definitely better than they used to be at letting Trump shoot himself in the foot
