I very rarely watch tutorials but the arm segment made this video worth watching.

Not only appreciating the low-level information in the tutorial, but also loving the SE: Lain production aesthetics!

I just discovered this channel, the visuals are super neat! The computers in the background, the Windows XP task bar and the window border around the web cam, wow!

Oh man, there are so many callouts to Serial Experiments: Lain in your staging/setting! Long time since I watched it, I love it!

The amount of effort and dedication you put in editing these videos is commendable👏 Great tutorial as always!

Thank you Laurie you have a rare talent - a thoroughly clear teaching approach. You provide just enough explanation of the reasoning, process and context without overloading the topic. Enjoying the low level assembly language perspective.

Never subscribed to a channel so fast! What a really cool style of video, with clear, helpful explanations. Good up the good work :D

What a wonderful gem of a video! Love the technical deep dive and the graphic design!

Current C++ core guidelines actually recommend against directly using new and delete in favor of smart pointers. std::make_unique and std::make_shared are the way to go. I also get that it's important to understand new and delete. Hats off to you for doing memory management in assembly!

I really hope this channel takes off. You put a ton of effort into your content!

@LaurieWired Thank you for this instrutive demo. I feel at home in the atmosphere you create in these videos, even though my house has never looked like this.

This channel was one of my best discoveries

Wonderful video. I love the comparisons between C & C++ and ASM. These are my types of video, contrast and comparison!

I like that you use the universal answer to everything for the content of the memory.

Thank you Laurie. I love that you run through the C version, being that it is the foundation of most modern memory allocation. The ASM version is absolute candy. Assembler is a dying art. More than ever becoming the domain of a very limited few. A simple clean run through the basics of a controversial and complex topic. 🥳🤓🤠

Incredible tutorial Laurie. This is so important for anyone working with dynamic memory. This is something I would recommend coding along on the Pi.

This my first video of yours I’ve found (thank you algorithm!) and I absolutely love your style. You’re an excellent presenter and the thematic aspects of an old Apple style GUI is charming without being repetitive. Instant subscribe! One small piece of feedback, the dark blue text on a black background was really hard for me to read with my color blindness, just a small thing but wanted to mention it.

I am relatively new to your content, but after several videos I want to say you are so easy to follow and understand, and interesting to watch as well with your videography and set. Your video and sound are great, and your presentation skill/presence is spot on. I hope to see you on stage one of these days at a tech conference if that is in your plans!

This channel is really impressive. You seem to have everything down somehow - you know a ton about the subject matter, your presenting is brilliant and you can distil your knowledge down, the video style and presentation is fantastic, and so is the cinematography. Really everything is brilliant, and it's clear you're still improving (e.g. I looked through the channel and your thumbnails have gotten way better over the past several months - I love this one and the recursion one). Can't believe I haven't seen your videos sooner. Looks like the algorithm has latched onto them though as I'm getting suggested a bunch recently.

Love the lain vibes Absoluetly a treasure of a show. Also, love the walk through thank you for making this walk through

Great series! I wanted to learn ARM assembly in my spare time and your videos are bite-sized and friendly to newbies

Perfect. Nowadays people do not have any idea about low level. Congratulations for bringing up your knowledge.

the production value is sick, cudos to that for the effort.

ohhh the Lain like intro has made me your biggest fan. Really enjoyed this tutorial and your knowledge. Hope to see more, especially around ARM based ASM. ^_^

Niche af but this is the best KZfaq video on memory allocation techniques I've ever seen by a country mile. Seriously, this is an amazing video and you should be proud.

this video is really great. very neatly explained and the speaker is fantastic

The effor to create the vfx for those videos are something to marvel on its own... What impresses me is that the content is even greater. I know my way around 6502 asm and seeing this made me want to do arm asm just because...

What a brilliant video, and it sure brings back memories *no pun intended* :-) I started with 68k ASM back in the 80's on the Amiga and continued learning C/C++.

Let's all love Lain!

Great video! Especially the assembly section. In my (albeit limited) experience, it often helps to allocate memory in terms of pages rather than individual bytes. The page size is definitely not a consistent or constant standard value that you can simply hardcode in your programs. Effects of page size (fragmentation or page faults) are super apparent when deploying anything large-ish scale (say PostgreSQL db) on your ARM device. If you insist on doing everything in assembly, make sure your program adjusts for this variability in page size when compiling and makes it so that certain variables are "aligned" well for faster access. Your C compiler will most likely already handle all of this better than you without you even realizing it which is why in my opinion, programming in C is a "safer" bet for performance, readability and your own sanity.

Thank you for the course. It was very helpful!

Just came across these videos. They are awesome!!!

Thank you! Crystal clear explanation :) Learned a lot!

Really nice video! loved the editing.

started learning C recently, very helpful. appreciate it :)

Great vid it is really enjoyable to watch and learn!

Excellent as usual!

A very useful lesson (in different languages!) and very beautifully told!

I didn’t expect this to be a good tutorial. You proved me wrong. Damn this is actually really good

I already knew how to manage dynamic memory in C, so I had a leg up, but those were all better examples than I can remember seeing anywhere else outside of Kernighan and Ritchie! I tried to learn C++ when I was 12, but the syntax seemed needlessly exotic, so I've avoided it since. Your example was clear enough that I finally see the utility though, for example, in its string formatting. I've also kinda' sorta' wanted to learn assembly for 25+ years, but put it off because it also seemed so tedious, but that was such a well motivated example that I have a real itch to try my hand with it in earnest now! Awesome channel-keep up the great work 🙌

amazing video from wired, thanks!

I also have to agree with most of you folks. This video edition is amazing! And thanks for the ARM part. I never saw an ASM code for ARM before. It's quite different!

My God, I love this channel

Heads up for anyone working in C, you don't need to worry about casting the return value of malloc. Unlike in C++, void* will implicitly cast to other pointer types without throwing an invalid conversion error. This just maintains symmetry with casting *to* void* which is implicit in both C and C++. It's ultimately a stylistic decision whether to keep the explicit casts even though they're redundant, but my understanding of what idiomatic C looks like involves just letting the language cast void* for you in basically every situation.

very dank editing.

Thank you for the lesson, your voice is incredibly clear and melodic.

the lain editing i love it!

just found your channel. very high quality content! I think I saw your presentation at Defcon last year (one of the few I managed to attend :D)

I am so glad the “serial lane experiment” is used in all your videos.

This is solid af. subbed. thanks.

Great video on low level programming, especially when explaining programming and memory allocation in parallel. Its even better than codeacademy and other tuturials that I've seen

My fav channel! ❤

Excellent! Thanks for this!

I love your channel, been wanting to learn arm assembly

Excellent video (and it also reminds me the number of memory allocation mess I did as an enthusiastic Z-80 assembly coder back in the days :D)

Great Video! Thanks

Thanks for the video. I learnt a lot about the French revolutuon.

Python enters the chat. "Memory what?" Python leaves the chat. 😁 Love your videos. Keep up the awesome and inspiring work. I'm digging deep into C++. It's pretty interesting.

Incredible thanks to keep it real !

I thought try catch was generally frowned upon. Thanks for the great info. Sick background btw

You were able to make a c/c++/ASM vídeo look modern and appealing. I love the "résistance hacker" aesthethic of it, that is the feel low level gives me. As for the content itself I'm still a student so I cannot opine on it, I'm just watching and trying to learn from it.

That's the cutest channel ever, loved it ^^

Hi, novice here. Thank you for posting this. I was wanting to learn more about safe memory usage but since I'm trying to teach myself this stuff, I had no clue how it actually works.

Wow, this was the most compact in depth video I have every seen, amazing. Thank you. What I don't get is why are you reassigning #-1 to r0 in alloc_failed, isn't it already #-1 in the first place?

Just discovered your channel. Excellent video.

Your opening of lain ❤, I love it

love watching videos on assembly. I'd love to learn more (mainly so I can confidently step through shared libraries while debugging) but I don't really know what a fun assembly project would look like...

Wow, the preswntation actually looks cool!

Great video!!

Beautiful teacher - thanks

Interesting to see that ASM malloc code including the explanations :) And this 90's transmission style is pleasant to watch. Dang I feel old when thinking about it 😅 Last time I've seen OS windows look similar was when Win 3.1 - Win98 have been around ...

Such an “ancient” reference to Serial Experiments Lain at the title animation! 🤘

Awesome intro!! One of my fav. miniseries. How did you get the whisper?

I see there are *a few* lain references in this whole channel, and I'm all for it

I love it, good tutorial. To visualize what is going on, it would be good to do it in debugging mode and look at what is happening in the memory.

Really enjoyable 😊

no idea who you are but the algorithm has blessed you. Subbed. Cool seeing code girls more often get recognized.

Just want to mention that the new in c++ is an override op, which means there’s a second usage for it, replacement new. You can place your data to a specific pre-allocated memory address. It’s a good way to do something like memory pool to avoid fragment/performance issues happen on traditional c++ new. (But be sure to do profiling because modern compile/OS may help you on this kind of things)

In the university I thought assembly was hard but with time, I began using... like it and is very easy... with it I learned to read all type code c,c++,html.

Props for good lighting technique.

lain mentioned! busy learning julia and data science rn but bookmarking this for later.

Thanks for showing the ARM assembly memory allocation example. KZfaq is lacking in good ARM assembly memory resources. I fumbled my way through doing ARM memory allocation using the brk syscall. Now I know where to go if I want to use mmap

awesome video Laurie, im learning so much from your work. Uhh can someone help me understand though, with the arm assembly example - was this emulated in the raspberry pi or on other hardware ? and in what OS is she editing the code and running the arm example?

Just as a best practice tip: always set your pointers to null after dealloc/free.

C++: Understandable. C: Ok. Thats fine. ARM V7 ASSEMBLY: "My God, my God, why have you forsaken me?"

Great channel, very good stuff. What operating system are you running?? super interesting!!

Very good , usefull information

Nice overview of code types 😊😊

Несмотря на то, что я знаю и английский и C, и C++, и немного Ассемблер, я ничего не понял, но получил массу эстетического удовольствия 😂❤ Присоединяюсь комментатором, которые пишут perfect.

I’ve been trying to pick up a bit of assembly recently. x86 rather than arm, but the philosophy is still useful. Compliment on the production and presentation btw. The videos look great! My first computer was a 90s Mac so it feels right at home and you use it to draw the eye to relevant information.

oh such nostalgia I love you I love c++

It's quite interesting to look in the assembly generated by the C++ and C programs as well. If you want to go low level with C++ you can use placemet new. It's used to allocate a usefull chunk of memory, like the page you allocated in the ASM version. At a later point you can decide which datatypes you actually want and you can do fast addr+sizeof(dt) shananigans.

Nice video. will have to watch again. Newbie on the watch!

The ASM version of you looks so happy!

hi there Laurie. that was a very nice explanation. I'd love to see some videos about Linux ELF objects both pie and non-pie. like, actually opening a binary, seeing the addresses, checking out the .plt etc. I haven't seen a yt video go that deep.

masterclass !

this video was recommended to me today because i'm usually playing tech videos in the background i completely forgot you work in security i was like "wtf...omg, laurie!?", hope you're doing well

Thanks for the videos. I'm only on my second semester of computer science and find a lot of this to be confusing, though I'm learning a little bit I think. Some day I'll be able to read and write assembly proficiently too.

Keep this up!! Love the video aesthetic. What do you use to create the VFX?

I hope this channel encourages more people to coding! I think if it gives a nice example to lookup to for girls to get into the field. You go and enjoy the coding people!
