Thanks, I enjoyed the video, I think that Real Time Operating Systems deserves also a video, and the Fair Scheduler in Linux too.

Please explain device drivers.

Damn, I’m glad I don’t have to deal with this vastly inefficient type of memory.

@coredumped can yu tell wht app use for the circuits or is it avid edit?

wow it's detail and perfect tanks?

a micro controller is better reduce human error while logic gates or pure transitor good for simple parts of circuit it can still be useful for microcontroller because logic gates are more power efficient but not cost effective on large scale

this definently more effort by using AI voice but at least its clear and well edited voice

0:55 Where is the *ASYNC AWAIT EXPLAINED IN 100 SECONDS* video?

hi brow, What software do you use to speak with text to speech? I'm from South America too

I wish this video had existed for me when I was first learning about IPC several years ago!

Then there's Read/WriteProcessMemory :)

Would love a Mach version of this! I know the Unix process model is so ubiquitous, but Mach's concept of Task, Thread, and Virtual Memory that processes can be composed of is super cool IMO.

Another thing with dynamically typed languages, is that they're great for making quick and dirty scripts or smaller programs, but the second a project gains any size, it becomes hell because by default you don't know what the types of values are being passed around into functions, so you either have to guess, or read up how every function you try to use works. Not to mention it makes LSPs less than stellar because it has no idea what types of values a function expects. Or what methods are attached to a class instance etc. Yes i know that JS has TypeScript to alleviate that issue, but imagine that we had to make a while wrapper on top of a language to deal with that problem.

Very good introduction

Hi, how do you make the animations? Which Software?

nice video！

Love your content

2024 IPC in Rust ...

In regards with consuming the messages by a server process, a video on reactor vs proactor model would be nice.

Is this the same for communicating with IO? (Memory Mapped IO vs Port Mapped IO)

Great video as always core dumped. Thank you for the content. I actually think I past my exams easier thanks to your channel. Regarding the performance, the communication is definitely much slower as you said. I had chance to work on a super computer with ~2000 cores. It is multiple machines w NUMA architecture, connected together over ethernet. Any communication would be extremely costly since over-ethernet networking, typically handled through southbridge, will be much slower than Memory Access, through northbridge. And of course the wait time by the OS contributes to the performance cost of communication. None the less, communication is inevitable on the way to scalability, so efficient communication it is.

goated channel

A video about CPU Pipeline someday, maybe?

I did OS during covid, and I passed even without knowing what a process is. Just crammed for the whole exam. Great visuals, now I am understanding

😢can we have lora signal instead of clock I think no

I wonder, if heap can be extended into the swap file, why can't the same be done with stack? That would avoid stack overflow errors when a lot of memory needs to be used.

Outstanding 👍👍👍👍

These vids are insanely good, you helped me a lot!

amazing explanation...Congrats

Excellent!

A note on the swap memory, it's not used as normal memory like RAM, but as a temporary space to hold less used data to make space for more important data on RAM, but since the CPU can only work with RAM, that data will have to be moved back to RAM eventually swapping with other data (hence the name). You really don't want to be forced to use swap, since the system will be constantly moving data to and from the swap wasting resources (though still better than crashing from running out of memory)

This man cleaned my soul.. Thank you so much for this video , we all needed this

Copy cut repair paste

9:51 , why i feel this is an open hole for malicious code to execute right there ?

Thanks!

This is so good for my soul, please please make more videos you explain so elegant and so simple it's mind blowing

Elegant and simple

best video i ever watch about the heap <3

This is so good! Thank you!!

14:41 that is assuming we need to preserve the order of the elements, which is not always the case. If order is not important to us, we could fill the gap with the last element of the array, making it an 0(1) operation.

As a beginning programmer, I don't care if it takes 15ms or <1ms to execute my code. If my monitor takes more time to show that there's been a change in speed than the actual speedup, it makes exactly 0 difference to me. What does matter is that someone who knows basic math can get incredibly slow code to do simple calculations without worrying if the variable type is the best. That feeling of having power over a computer instead of it overpowering you is incredible! If I'm designing an application, I will write it in a lower level language to get the performance I need. If I'm trying to get the computer to output 2 + 2, I do not need to know whether it's an integer, unsigned integer, or a floating point value in hardware. The respect I have for people who actually care if their code is 700 KB or 7 MB is astronomical because they are so much smarter than I am and can make real change. However, I just want the screen to say "Hello <my name>". If a language will baby me enough to let me do that without thinking about what it "really means" in the CPU and memory, I will choose that every time. Is it a skill issue? Yes, it is and I don't care.

I thought CPU process handling was very elegant, but just copying all the data is just disgusting. I feel cheated.

9:45Imagine you explode a rocket because yoy forget to add a extra byte

0:19 You just had to do that didn't you? x, y = 0.0 and x2, y2 = 0f64 Flexing knowledge

bro youre awesome, thank you very much for the explanation!!

5:10 to be pedantic OSes with memory protection (i.e SEGFAULTS) mostly act only when unallocated memory is written to not read from. I experimented with this on windows before on both the stack and heap memory address spaces, funny enough the stack had little to no SEGFAULT upon tests due to the fact that C/C++ allocates variables on the stack for a function at the beginning regardless of the scope which it is defined in. Also windows was not the right OS to test this out as most of the time the preferred action is too terminate the process without an error message leaving me to manually catch the SEGFAULT signal and output an error message

The Question here is that we as a software developers do we just need to learn about thoes topics in a basic way know what that do and why , or not knowing them will effect our job ? I mean the web dev backend & machine learning
