Yeah I’m on voyager too and home stopped working for me at the same time as this hidden community issue. Home and All are literally the same feed now. Curious if these issues are related.

Lol it refused to post this reply until I logged out then back in, whereupon the issue was fixed. Guess that answers that.

I’ve tried to hide all the moes but it feels sisyphean. I hide cyber moe, military moe, office moe… but the next day someone is going to start taco moe and I will see a half naked girl with cheese hair and a lettuce bra. There is no escape.

Hmm… the first three are the reals, but the last one is the rationals. Am I reading that right?

I live in Washington state and I’m pretty certain the sales tax here is 10% (slightly higher than your maximum figure of 9.56%). It’s a pretty well known trick here that you can account for tax just by decimal shifting and adding (ex: 5.29$ without would be 5.29$ + 0.529$ ~= 5.81$ with tax). Is that 9.56% an “in practice” figure that accounts for rounding down? I’m curious where you read it.

I wouldn’t say that it’d be strictly impossible, however if it can be done then it would come at a considerable cost to useability, versatility, etc.

One adjacent concept that comes to mind is the use of the :visited CSS tag to extract a user’s browsing habits. I remember seeing a demonstration of this where an “are you human” captcha was shown but the choice of image in each box was controlled by the :visited tag. I can’t find that post, but this medium article demonstrates a similer concept. There are mitigations to this luckily, but a fullproof solution would be to remove the tag’s functionality altogether, which would make certain websites (like the one we’re on right now!) much more inconvenient to use.

It seems trivial to me for a website to detect user behaviors that indicate the use of an adblocker. For example, if a request for a page is immediately followed by a request for a video on that page, rather than after 5-60 seconds, then they’re likey using an adblocker. If there is an ad placed between two paragaphs in an article, but two distant paragraphs are visible at the same time, it is more likely (although not guaranteed) that they are using an adblocker. If a user triggers an abnormal amount of those heuristics then they get flagged as an adblocking user.

I agree pretty strongly with this generally. The farside has a way of having jokes that are so simple on it’s face that I’m left thinking “surely I’ve missed something?” Usually it turns out that no, in fact, I got the joke and was just vastly underwhelmed.

For whatever reason I found this one to be mildly funny. Couldn’t tell you why. Perhaps it’s the idea that the people who built the atomic bomb weren’t that smart after all?

I’m no biologist, but I’m pretty sure that this photo I took a while back has a lot of lichen:

That flakey & coral-looking stuff growing on the branches should be lichen.

Uganda ain’t blue enough!

I honestly assumed I was colorblind in one eye (I am diagnosed, at least)

The thing that finally got businesses to finally get off IE wasn’t from the browser being worse than every other option. Heck, it wasn’t even because it was a decrepit piece of software that lost it’s former market dominance (and if anything businesses see that as a positive, not a negative).

What finally did that was microsoft saying there won’t be any security updates. That’s what finally got them off their ass; subtly threatening them with data breaches, exploits, etc. if they continue to use it. I don’t see google doing this anytime soon, at least not without a “sequel” like microsoft had with edge.

Surprised TOEM isn’t on your list, given the premise is pretty much exactly what you describe. Last I checked it comes up on the first page or something if you sort steam by highest rated.

Lunacid might also be a good game. I think it fits your criteria for me, but that might just be for me.

I dunno, having two primes sum to a power of two is undeniably powerful in my experience. The number of times a calculation goes from tedious to trivial from this sum is incalculable. The lowest I’d put it is A.

Isn’t the Weierstrass function a counterexample to the premise? Wait no, I misread. It’s the converse.

I have mine set up with a bunch of categories that are sorted with a prepended 3-digit number. Allows me to have different sections of category without it getting mixed up. ex:

010 S
011 A+
012 A
013 A-
014 B+
etc...

When I read the problem description I expected the input to also be 2 digit numbers. When I looked at it I just had to say “huh.”

Second part I think you definitely have to do in reverse (edit: if you are doing a linear search for the answer), as that allows you to nope out as soon as you find a match, whereas with doing it forward you have to keep checking just in case.

Oh yeah, I misspoke, gonna edit.

hmm, my code keeps getting truncated at for y in .., anyone have any idea why? Maybe the “<” right after that confuses a parser somewhere?

Did this in Odin

Here’s a tip: if you are using a language / standard library that doesn’t have a set, you can mimic it with a map from your key to a nullary (in this case an empty struct)
