Study math for long enough and you will likely have cursed Pythagoras's name, or said "praise be to Pythagoras" if you're a bit of a fan of triangles.

But while Pythagoras was an important historical figure in the development of mathematics, he did not figure out the equation most associated with him (a2 + b2 = c2). In fact, there is an ancient Babylonian tablet (by the catchy name of IM 67118) which uses the Pythagorean theorem to solve the length of a diagonal inside a rectangle. The tablet, likely used for teaching, dates from 1770 BCE – centuries before Pythagoras was born in around 570 BCE.

Cool stuff but god damn I miss RedditIsFun showing me what links are before I opened them. I'm currently in bed next to my sleeping wife and that video was suddenly very loud.

Sync for Lemmy also shows a preview of the YT video.

RiF transplant (I used sync for reddit early on in my redditing)

It's been nice

I used RiF for 9 years. I miss it too. But I'm using Sync for lemmy and it shows me the full link and that it's from YouTube. Maybe check it out.

Is there a paid version of it? I'm only using free apps because I'm literally so poor dirt is offering to help me, and when there's two versions of an app they usually make the free one pretty bad on purpose to get you to buy the full version.

The only difference is that the paid one doesn't have ads. I don't know what's going on, but my free version doesn't have ads either.

Last I checked, if you deny GDPR / ad personalization thingy under Settings -> Privacy, ads are not shown (There is a box, but it is blank with text "Sponsored content").

Certain views did not show ads as well.

I'm using Voyager and have never seen a single ad. Out of curiosity do you have AdGuard on your device or something else that would catch ads before you see them?

I use Small Cards layout and it looks like there's a bug (it's not a bug, it's a feature) where it won't show ads in this layout. It will in other layouts.

That's a bit of a bummer, I don't use card view, I always use the most condensed option I can.

I recommend urlcheck from fdroid. Shows you the url and plenty of other features like removing tracking parameters

Rookie move. Always, always, always check phone volume before clicking any link.

Connect for Lemmy does that, and it also has a UI rather similar to RIF. As another RIF refugee, this is by far my favourite Lemmy frontend

For iPhone users, you can press a long click to preview. I’m using Voyager as a PWA and so far it’s better than all the native apps I’ve tried. I don’t really use Lemmy on the desktop because the url isn’t muscle memory yet.

I'm on Jerboa on Android, I seem to get that option too. Thanks for the tip!

Same here, Voyager is the best so far and they’re updating it constantly plus it’s the most like Apollo which was my favorite. Don’t know about the preview button, thanks for the tip

Weird I'm using Voyager on Android and don't think it does that, but I'm loving URLcheck as recommended by another guy.

It's an iOS feature, I'm pretty sure. Works on just about any hyperlink I think, I just sell the things though. I don't actually use them.

I set up a do not disturb schedule on my phone to avoid that. My apologies. I usually put what I'm linking to somewhere in the text (e.g. Wikipedia or YouTube).

Oddly enough my DND is supposed to be on schedule right now as well and it still played. 😂

I just posted a news article in the dungeons & dragons community (DND) and your comment was very confusing for a second. Check to see if your DND covers media. Android separates alarm, notification, and media volume levels again. (Assuming you're an android user.)
