How Data Structures & Algorithms are Actually Used

[@fknight]

Alright, so NVIDIA and I are giving away an RTX 4090 signed by NVIDIA CEO, Jensen Huang, as well as 5 DLI credits. If you'd like to enter, all you have to do is: - Register virtually to GTC 2024 at this link (it's free): nvda.ws/3kEyefH - Attend a GTC session, take a screenshot of it, and fill out this form with the screenshot and contact info (in case you win): forms.gle/cJ7xS9VrvzH52Anu9 That's it. Good luck!!

this comment says "1h ago" maybe you should teach them devs in google how to develop

THANK YOU VERY MUCH FOR THIS! Finally someone who not only talks about DS&Algos, but also shows where and how it is used in real projects! For a world with more of this!

[@BrahimDriouch-oz6uv]

This is the kind of content we need as self taught apsiring developers and hobbyist. We have watched a lot of videos and tutorials but we need to see the real world use cases. Thank you.

[@wellingtonmusicas3144]

I've watched countless video about data structure and your video is by far the best, because it not only show what is data structure, but also how it is applied on real-world structure work. Thank you very much.

[@deenpc_life]

dangg your video editor deserves some raise ! or maybe you're the video editor

[@samatech8853]

Thanks for clearing my thought for me

[@arsnakehert]

Who follows who in a social network is a great example of a graph, if you have junction table representing a "follows" relation it is pretty much an adjacency list representation of a graph, where the foreign keys are "pointers" to the nodes which are user rows

[@hirookenji]

I was watching one of your videos 8 months ago and explored your channel to check about your new content and hey, this guy is a whole new person.

[@TANCEUS]

your videos are so helpful ❤

Even though I didn't understand it all. I still enjoyed watching it and learnt something cool.

[@ahmadghalioun7310]

For retriving data from the database you can use indexes to improve speed. Never heard that data structure or algorithms is useful for such use case!! Cool project by the way . Working on something similar.

[@theghost9362]

3:32 hey I have a question , why didn't you sort the data in the DB instead of doing it in the front-end, is it costly for the DB ? or is it faster that way ?

[@JoaoPedro-qt7dc]

Good question. He sorts by the created_at desc, so it is sorting the data in the DB, and then sorting again in the front-end by the vote count. I suppose that he does so because sorting by created_at date at db is the most common case, so when used the function is used in other places (the home page?), it does not need to be sorted in the front-end. In this case, as he was in the most upvoted posts page, it makes sense to reorder again. Also, he is not paginating the query made, which is kinda weird, because it will bring the whole table, a no-no. Maybe I missed something because I'm not very familiar with that ORM, so if that is the case, please ignore this statement. * It makes sense, but is debatable. Why is that so? Because you are reordering two times. Maybe it is pre-optimization, but a better approach here would be to sort by created_at desc by default, but also have parameters in the function to customize the order by. That way, the reordering only happens in the DB and does not need to occur again in the front-end. **Every approach has its advantages and drawbacks. Maybe the benefit of reordering only once at DB is not worth it because of the trade for complexity in the code. Example: sanity check the passed parameter, map parameters to table columns, how would you handle if you had to order by more than one column, creating indexes in the table so the order by is efficient, etc. If you want to deliver a MVP faster, sticking with his method is a better fit because you don't have to trouble yourself with that kind of thing early on, so this can be refactored latter on.

[@RealBillcollector]

hey bro, tell me if you found the video

[@maguilecutty]

This is great content! The problem with modern development - in particularly JS and Python is that they are abstracted from the actual algos that happen underneath them ie ur eg with sort. I started with Java 22 years ago - left it for 15 years and when I came back to programming and started learnign JS it confused the f*** out of me cause I couldnt see the magic happening under the hood - like where are these things happening? Am i missing something? i think every programmer should start with somethin like Go or some other mid teir language and learn these fundamentals - but its hard to make people how much they will regret not learning them until they are mid-adv level and they ahve no choice to...meh

[@ridabrahim7604]

i'm still confused about the use of many data structures, i made a web app for my final project and created news feed but really all i did is query the database and the return value was dictionaries stored in a list and i didn't order them after loading them, i ordered them by publishing date from the query itself, i just feel like some things aren't used as we new programmers think it's often used, video on my account click me to see what I'm talking about

[@centripetal6157]

Data Structures are all about ordering and arranging data in different ways... Depending on how you want to display or store data - you could have used different methods. In your case, you were storing the news feeds by date - which is essentially stored in a list (array?) in the database. If you wanted to store data in a different way, you could have depending on the app type and the amount of users using it...

[@ridabrahim7604]

@@centripetal6157 i was storing the data in database and when i select the data it comes back as a list of dictionaries, my query also brings the data in order from the database table before i even load it to list of dictionaries, this is good ( i think ) because I'm not giving any sorting possibilities for the user, it's just get data, load it to list and loop over it to display it

Apropo - for all u beginner-intermediates reading this - go learn a mid level language like go where at least a large part of the magic languages like JS do is abstracted or you will regret it later when u go to ur mid/senior level job int and have to do algos. Youll thank me in spade beleive me!
