For people disagreeing on the stack grown upwards (address) in the animation. As someone else commented: "Growing downwards is a convention from when computers had small memories and the stack was placed at the end of the data segment... nowadays the stack can be anywhere, but the convention stuck on, at the end of the day it makes no difference".

there is severe lack of educational material on youtube that teach conceptual subject of software and programming, I'm glad I found your channel keep up the good work my friend !

Code salesman: **Slaps roof of stack** "This bad boy can fit so much data in it."

People who explain complex things in this simple way are considered a rare coin. You have gained a large number of subscribers with only three videos. Please continue, perhaps this channel will achieve great success.

Only 3 minutes in, but I've had dreams of a youtuber with such a beautiful and minimalistic style that doesn't just go over brief basics. Thank you! Edit: It's so deeply upsetting that the best and most interesting learning channels get such little attention

These are some of the fundamentals that should be covered on any software development educational setting, specially when they're presented in such a visual fashion. Thank you for making this.

Masterly done, the best video about the stack. A gem. Unfortunely not all people are made to teach.

Thank you dearly for going over everything you did. Please don't ever feel pressured to summarize or assume the viewer knows, if everybody assumes that everybody already knows (as much of the programming world seems to do) information becomes insular and difficult to access. You're doing an amazing public service.

This was the PERFECT length and complexity for an introduction to this topic! Concise, yet doesnt presuppose a ton of knowledge, while also not delving into a bunch of side comments on details/scenarios that do nothing but stroke the creator's ego while confusing the audience :) JUST enough to know where the OS fits, types of memory, stack size constraints, etc., to understand the implications on performance and utilization, while still focusing solely on the stack itself. It leaves the viewer with tons of questions to learn more, but few to no questions about the content presented here. Bravo!

It's just great! I watched other videos about the stack, understood how it works, but there were a lot of questions, and in this video you just visualized everything perfectly and explained it! I'm really looking forward to a video about a heap

I really appreciate how considerable you are for mobile viewers. Many programming youtubers just show their computer screen and the letters of the code become miniscule

Incredible video! As a 4th year CS major, I haven’t seen such a detailed and intuitive description of the stack in any of my classes. Looking forward to the heap video!

This channel is GOLD 🔥! Now I know what the Cache, Swap etc is. True gold! Please keep making these videos ❤

This was such an amazing video. I really believe the way this video articulated each point and built up to the answer. The pace was also great. Please keep up these sort of educational low level videos!

I'm mainly only receptive to video educational content and I found yours to specifically resonate with my learning style. Earned a sub, well done.

I’ve always been interested in programming on a conceptual level, but never really had the time or resources to research them myself (I’m just a hobbyist, who’s learning in my free-time). Your videos are very fun and interesting to me and I feel like I’m learning a lot from them. I’m very excited to see more in the future!

Good educational and informative video, as always, nice job!

Best video I’ve seen in a while. Perfect blend between programming and hardware information.

I've been looking for some explanation like this for years, so I could understand some concepts which didn't live my mind for all that time. And this channel just appeared in my recommendations. Thanks for very informative video.

Dude, finding your channel was awesome. As a chemist who likes to code the repetitive homework stuff, learning these concepts is very nice insight. Thaaaaanks!

i really like how elaborately you explain these concepts, as someone just getting into systems programming, your videos are really helpful to me

Amazingly done. I finally understand what on earth the stack even means. Why its so fast is secondary. Thank you for this !

This UKpostsr is cracked mannn let’s go!!! Such a beautiful presentation of knowledge, thanks man! Keep doing what you doing brother 💪❤❤❤❤

More videos please! Your method keeps me from being overwhelmed.

Great vid! I have always wondered why I can't add to an array, this makes it perfectly clear to me

Great video, thanks for sharing this knowledge.

I incidentally did happen to know all of these things already, but you still get a like from me! The visuals are excellent and the topics are some of my favourite. I look forward to more like these!

This was such a great video. I learned this sort of stuff in university, but i always find it tough to brush up on outside of that environment. This was thorough, entertaining, and not bogged down by hardware specific implementation details. Subbed and looking forward to all of your future work 👍

wow i got recommended this video and damn it makes it so easy to understand with animations man THANK YOU!

Your clear explanations and diagrams in video are very intuitive! I have comprehend a lot of things than my university experience.. appreciate that!!!

I think this is the first video I've ever seen from this channel. Really liked it.

I love your teaching style and sense of humo...

Excellent work, pure content with simple description and impressive animation. You hit the point with every sentence. I'm looking forward to the "heap"

Excellent, as an embedded software dev, these kind of videos are a rare gem. Keep em coming

Wow this was awesome! In all of the discussions on stacks and heaps I have heard online and in university I’ve never heard anybody explained that the CPU has a stack register. I can believe I didn’t know that. Makes a lot more sense why the access is so fast.

I'm learning about memory allocation in c++. (self taught). I have watched numerous videos on stack / heap. They are all very confusing and the fact that you did this so well in such a short time is of great value to me. I know have a understanding of whether i want to choose stack or heap. I also understand why i would use the smallest primitive type possible so that the cache is not wasted. Very greatful. Thankyou

That was the best explanation of memory stack I have ever seen.

Your upload schedule is amazing. Keep up the good work.

I don't know what I'm doing but it's probably right cuz i got this video in my algorithm. I can't believe how low the subscribers are on this channel when the quality of your content is so high. The minimalistic style of animation is also a huge relief as compared to others who focus more on the animation than the explanation. This was a breeze of fresh air. Excited for the video about heap!!

This is a very well-made video about stacks. Nicely done. 5 gold stars for you.

What a concise explanation accompanied by a very intuitive graphics! Kudos to you! Please continue delivering this kind of high quality videos 😊

Your style of explaining is quite comfortable to follow and easy to understand. Keep making these videos. Already subbed !

Thank u for sharing this much brilliant knowledge. I’ve learned a lot from this video. Appriciate it 🥰

if teaching something an art, you are the artist. I speak python and now a days learning c++ just for fun and your videos explain a lot of things here.

Great video, you are doing a great job explaining low level concepts in a very digestable way. I am excited to see your next videos

You have earned my subscription, that was a better crash course than my SOEN classes

Best low level content on this platform. No question

This was a really cool well explained video. Please do more of these!

Exceptionally Great explaination with examples. Keep teaching stuff like this.

Best video ever! Keep this awesome channel growing!

Very eloquent and detailed explanation. I liked the animation too. Keep it up!

this is some phenomenal explaination, i think its even better than my uni courses, well done, looking forward for more videos from you

waaaaaaauw!!!!! neighter in university nor in any other place nobody explains that how stack works and how processor cache works. you're awesome bro.

Thank you very much~ I totally love this video. I finally make myself clearly understand these foundation knowledge;) I have been told again and again that allocating in stack is faster than in heap but no one try to tell me why before you XD. Thanks thanks thanks~

Another amazing video, thank you for your time and effort!❤

Great animations and concepts; brief, but thorough!

This is great. Easy to understand and follow.

Your style of teaching is good. By starting with a misinformed premise, then correcting it, using it as cure against "this is why we don't just do that". This is typically the reason why I don't understand many concepts, not just in compsci. "why doesnt it just do *this*" and then I can't accept the information given to me because I think it is wrong information. This is important, because the way we learn is by building a tower of understanding using smaller blocks. If any of those blocks are wrong or misinformed, then the whole tower will fall down.

Thanks a lot for going into such detail. This video was so well crafted, definitely subbing. I was curious if you have any recommendations for other resources which go into systems concepts that you’d recommend

Can't wait for the Heap video!! This was great

This has got to be one of the best videos I've watched on UKposts concerning the art. Thank you so much. Do you have any book recommendations? Edit: And I hesitated to watch when it was recommended to me 3 days ago. Fast forward now I'm subscribed!

This is amazing, looking forward to learn more about optimisation and security

The stack usually grows downward from before the kernel, giving it plenty of space, and reducing the chance of a stack overflow. Theoretically, you could get the stack to loop back around, but even then, data grows upwards from right after the kernel, so you would have to fill your stack a lot, so that it loops around (I have seen examples where that is 524,288 memory locations, and that’s for a raspberry pi), and then have so many files that it is feasible that the stack will overwrite one.

This channel is like a breath of fresh air for someone like me who's trying to learn Rust but hasn't studied CS formally or been properly exposed to the fundamentals. I'm not a bootcamp graduate, I'm just a self-taught frontend dev who's trying to break into systems-level development. Keep up the great work ❤

Loved this video. Great explaination, high video quality and a wonderful illustration!

Amazing video and the visuals were really on point. Thanks!

holy.. i knew everything you said in this video but maaan.. that animation! love the video, sub clicked! teaching in a visualized way is the best!

Hi George, love your videos. Thanks for this good work!

My new favorite channel. ❤

Very concise and logical pill of knowledge on topic with nice and clear animations. Very good job! Level of expected prior knowledge ideal for topic. Againg great job sir! No need to excuse for simplifications, level is exacat how should be for this form and topic.

the best explanation i have ever listened

Great video! Liked after hearing the proper use of the word “datum” at 8:28. 😉

i am eagerly waitin for more your content, after working 9 years in the industry as app and web developer, I want to dive in low level programming, but only two channels I got which are educational, you and low level programming. keep posting

Most of this stuff I already knew. But I was always concerned about knowledge holes. The way you explain things in your heap video and ESPECIALLY this one reassured me of the things I knew, explained things I never questioned just enough to allow me to piece the rest together by myself and explain things I didn't know before so well I could just pick them up without issue. If I had to suggest one thing it would be to make followup episodes on topics to explain more advanced concepts. Like in which direction does the stack grow and why? How do function calls store data on the stack to return? What are stack cookies and how do they contribute to security against buffer overflows? How does malloc organize the heap? Stuff like that for example. You don't see this often on UKposts at all. Take my sub! If I had the money I would become a member without second thought.

awesome video, just like the last one. please do make a video about the heap and virtual memory. thank you, stay well

Great video, great explanation. I didnt know anything about this and i learnt a lot.

You boy this is dope as f# , please continue making videos it makes me excited for computer science

Superb video, thank you so much, love from India 🇮🇳🇮🇳🇮🇳

This video is great also for those who already understands the concepts, because they always struggles to explain memory management of OS due to its complexity.

Dude wtf this is so good, please dont stop doing this

I love this content, great job!!!

Although I know the topic, it's interesting to watch this video. I like visualisations. Thanks, waiting for heap!

Great video! Really clear information and I like your humor lol

Thanks for the knowledge!

If my lecturer had taught computer architecture like this, i would have really loved this subject :3

Phenomenal video, wow, thank you!

While the computer voice is a bit strange at first, the video is definitely pure gold. honestly, it's awesome to see such great content on youtube, definitely keep up the good work! btw, it'd be awesome if you could add the sources to the description :D

This is great I was struggling to understand stack vs heap

Very good video, the only point missing is why their is padding and memory alignment. The answer is that it is still cache related, but it's a little more complex so understandable it was not mentioned.

Love this. Thank you!

This is a fantastic video. Thank you! Subscribed!

How much background work and knowledge does it take to explain it so neatly? It's pretty amazing.

Thanks a lot for a such complex and usuful subject.

Great video. Love to see more!

This is very educational, the type of knowledge that I am not taught. Please do a video about the CPU

Peak of computer science knowledge explanations.

Today I understand why use stacks or how memory allocation works 🎉 your video is best it😊

i love this style of video!

Keep it up man, i love the low level stuff

hey your explantions are so good... please speak about virtual memory too in a next video ... thank you so much for making such amazing content and keep continuing doing the good work.. cheers
