Hello Tildes,

I am currently taking DSA in college and struggling a lot with the math and algorithms. Recently had to solve Karatsuba questions and I don't even know what I wrote down on the paper. I have been trying to look for videos on this and only really came away with a vague understanding.

What I've noticed is that I struggle with solving the math part of the questions.

For example: "Describe a divide and conquer algorithm to compute the square
of an n-digit integer in O(n log3 5) time, by reducing to the squaring of five [n/3]-digit
integers"

I have zero clue how I am supposed to understand the latter half of the question. It makes no sense to me beyond I am supposed to be multiplying squared numbers. How do I even begin to turn this into an algorithm? What is the solution even supposed to look like?

Needless to say, I've struggled with math my entire life and I've been trying for years to be decent with it, and I have nothing to show for it.

So, do you have any recommendations that could simplify the math needed for DSA? Videos are preferred but I will textbook recommendations as well.

Thank you, and have a good day!

situation: Watch video until the end, and want to get back to "home" with as little drama/clicking as possible.

Current process:

• hit the tiny ass'd "x" at the top right to close the suggestions overlay (usually after several attempts)
• drag the video position back 30+ seconds so that the "up next" overlay is no longer obscuring the minimize video carat in the upper left.
• hit the tiny ass'd minimize video carat (usually after several attempts)

I keep wishing there was just a 'go back to home screen' option available at the end of videos that I'm just missing.

Youtube has become rather broken of late. The nagware popup complaining about my ad blocker can no longer be removed. I don't want ads and I certainly aren't going to pay. So far, I download the videos via Jdownloader. Is there a less bothersome way? How do you go about it?

With the Youtube adblock debacle going on, and my account on Firefox+Ublock getting the dreaded popup, I was trying out the Piped alternative frontends for Youtube. If you're unaware, this is basically lets you browse Youtube without using the actual Youtube site or your Google account, and there's no ads. Whenever this adblock issue comes up, everyone starts pushing other frontends like Piped as the solution. There's also a dedicated bot that automatically replies with the Piped link when anyone posts a Youtube link on Lemmy. People seem to think very highly of this site! The simping for it can be very strong.

I tried using the main instance, https://piped.video, but it was laggy! Completely, unusably slow. I've also had it crash whenever I try to watch certain videos. I heard there were other instances that would have less users and less pressure on the servers, so I tried out the other public instances. One of them worked great for a couple days, now it just stopped loading videos all of a sudden. All the other instances I've tried either don't load videos, or the domain is down.

Are they cracking down on Piped now, or are all these instances just not good and you need to self-host to get anything out of Piped? Are there any other alternative frontends that you've liked?

Youtube is flooding with very hot models all doing some pilates and yoga claiming you'll get big gains in no time at all.

I'm looking for a sincere, honest and non-flashy 20 to 30 min video that works both my core and bum region.

Hopefully some of you have had the time to dig through all of the weeds.

I've always been a bit of a privacy enthousiast. Have had everything blocked that Google and by extension YouTube wants to scrape off you. This means I've also blocked my view history.

Recently YouTube started giving out a warning on the homepage that you have blocked your view history, that you can change it in your privacy settings and that it helps them serve you better content. What it also means is that your homepage is just one big popup to guilt trip you into sharing your data. The homepage won't show any suggested content anymore.

While it is in their interest to do so and since they are a company wanting to make money it is understandable. Nevertheless it seems harsh from going to see content that you might like to only seeing a big warning sign right now.

What are you experiences with this?

I absolutely adore both, it has such a relaxing animation style and soundtrack. Kind of an embarrassing guilty pleasure as a guy.
The soundtrack is partially by the artist Baths who is also incredible. And I just saw its been released sometime recently!
Anyways please leave your thoughts about the show, I hope it gets another season, which is likely since they were partially acquired by Toho studios
