How? How to create shared memory IPC calls?

I stumbled upon your videos just yesterday. Wish you made them a decade ago-they would have cleared all the questions I had about OS, CPU internals, and how bits drive hardware and software. I'm really excited because your videos explain the most sophisticated stuff about CPU/OS in such a simple way, and that too with great and simpler visuals. Truly amazing work! Thanks a lot, man!

excellent

Bro had Prime's 2 Idiots 1 Keyboard up ☠😆 Amazing Video

gem

This was a great video explaining how DRAM works! 🫡 It's not within the scope of this video per se, but this also helps explain why DRAM has timing/latency values. A capacitor can't charge/discharge instantaneously so you have to wait a certain period of time for them do to that. And if you don't wait long enough, the voltage values are probably not within tolerance.

Absolutely outstanding. Keep up the great work. Perhaps the best content I've come across that has explained things concisely and effectively!

9:24 so the system calls or function like open() are implemented in the library we use with our programme and only the interuppt part of system calls is what switches to os interrupt handler , then it means the system calls are implemented by the user or library and not provided by the operating system ?

Yes another BRILLIANT video. Thank you George.❤

no college curriculum can emulate videos like these

Man I didn't know that flip flops worked because of the inverter delay. Awesome

The animations are actually amazing - great work. Really informative and familar if you're used to working with FPGAs.

2:25 tldr stRt

This control unit is Hardwired in RISC and Microprogrammed control unit in CISC

I used to kind of try to explain the difference between device drivers and user software like games to explain the Crowdstrike issue - and it kinda worked. But now, I'll just point them to this awesome explanation video. Well done, George!!!

Even with the four year IT training having hanndled electronics 1 and 2 I couldn't understand this till now just within 13 min

Man I love this channel. Great content. Very informative

13:19 And the HAL makes sure it isn't even more stupid.

early

I remember, in the late 80's there was a Modula2 compiler for MSDOS including the source code for the PROCESS module and the source for an timer interrupt handler (written in M2) acting as scheduler for the process queue. That was quite useful to understand how multitasking works under the hood and what issues need to be solved when synchronization between processes becomes important . Unfortunately I don't remember what exact M2 version that was.

but doesnt all that switching introduce a lot of delay??

This is awsome, lets make this channel go Viral

What a gem of a channel. Also, a question: why do the constant values need to be stored separately from instructions?

the modern family part had me rolling. dude dont worry most of the science channels are presented with accents and we would understand you more than the broken english americans use

Oh, my god. It all finally clicks now. So, multiple Python exes with different text files are being used, and in some cases, the main.py or whatever data is being used. Wow, I think I understand now. Thank you!

Mach is pronounced like "mock"

These videos are absolutely incredible - can you please make one where you describe how virtual machines relate to their host operating systems, and contrast that with how containers work, with animations of the address space? I'm wondering if virtual NICs are implemented any different than what's presented in this video.

What would prevent the user code to call that interrupt?

your text to speech is very annoying

TTS, and an elementary presentation. But it's clearly explained.

thanks for the video great explanation

Thank you! I just learned something new today. 😁😁😁😁

Thanks for this great video, easy to understand, well put together. Waiting for Threads specific video - concurrency,locks, synchronization. When is it going to get released ?

I remember programing on the DEC Alpha back in the early 90's, one of the first 64 bit processeors, the manual mentioned to use natural size processor uses for numbers as that is what it fetches in. If one make the size smaller ( for some size worry) the cpu fetches in the full size and then has and then cut down to size the programmer suggested. More instructions being executed. For most apps it slows things down as more processing is required to downsize to the programmer suggested. So making it smaller is not always optimal.

your videos are brilliant

Make a video about 'stream' concept, how it abstracts away how data is exchanged from various sources. In programming languages they use streams assuming people know what it's, but only by coding something with them i understood how they work.

holly smokes, i love this channel. thank you sir

u're the best ! thx !

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

report for AI

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 :)
