nice train example!

This is the finest video on GOT, PLT topics. Thanks for your efforts.

Really appreciate the clarification on the server side of the two different fd's. I think that was muddy in my head and now with the diagram and your explaining the difference, it all makes more sense!\

Gemini 1.5 Pro: This lecture is about memory mapping (mmap) and its role in virtual memory. The speaker, Chris Kanich, explains that memory mapping is a technique that allows a process to access a file as if it were directly mapped into its memory address space. This means that the process can read and write to the file using normal memory access instructions, without having to explicitly call read or write system calls. [1,2] One of the benefits of memory mapping is that it can improve the efficiency of memory access. When a process reads from a file using traditional read system calls, the data must be copied from the kernel address space to the user address space. This copying can be time-consuming. With memory mapping, the data is already in the process's address space, so there is no need to copy it. [1,2] Another benefit of memory mapping is that it can simplify the process of sharing memory between processes. Two processes can map the same file into their respective address spaces, and any changes made by one process will be immediately visible to the other. This can be useful for things like shared libraries, which can be mapped into the address space of multiple processes at the same time. [2] The lecture also discusses the concept of copy-on-write (COW). COW is a technique that allows multiple processes to share a read-only page of memory. The first process to write to the page will cause a page fault, and the kernel will create a private copy of the page for the writing process. This means that the original page can still be shared by other processes, and the writing process will not affect them. [2] Overall, memory mapping is a powerful technique that can improve the efficiency of memory access and simplify the process of sharing memory between processes.

Great explanation Chris. Keep uploading.

I've been doing packet decodes from packet decoders where first introduced (really before Ethernet was invented) and have read and watched seemingly countless examples of tutorials on this subject. This is easily the best one anywhere.

I'm soo in love with your way of teaching this is so unteresting !

Great lecture! I'm wondering why is spawning subprocesses for ulimit and wc here?

Thank you. Please keep sharing!

This is probably the most in-depth (and clear) explanation of sockets I've seen yet. Thank you very very much.

Hello, Is the entire playlist here on your channel?

great video.this video clicked the javascript event loop for me.

Thank you for making these lectures FREE!!

I really wish you didnt waffle on about a separate topic for 3 minutes in the middle

I have few words: crystal clear

Wanted to add in another thank you for all of your videos. They're really helpful for teaching myself material that I never had the opportunity to take classes for in college :)

It is also worthwhile to test that the system does what the documentation seems to imply it should do. Try mmap on a large file using different flags, see what happens when the file is cashed in main memory.

Finally I found a channel that was looking for a long time. Thank you 🙏

Good video

Every word of this video is gold! Good job explaining it.

what is the name of the book please ?

atomic?

thanks for this.

Thanks

Thank you!

This is the gold mine I have it. Kudos to the instructor. ❤it

So good.

For anyone wondering, he's using the example coming from Computer System: A Programmers Perspective !

this is so good

Beautiful & Unbelievable, how on earth you made it so simple !!!!

nice explanation man, keep up the analogies! <3

Another way to fix compilation error of multiple definition of `x', one can add `extern` to `int x` in weaklibrary.c. e.g., `extern int x`.

simply the best 👏🏾

When someone on KZbin compress your 4 hour lecture into 20mns :D

chris you are a talented teacher, you should learn all areas of ECE and make lectures for all topics!

Thank you so much for sharing!

Very good. keep going. Thanks.

Nicee

This is a TCP/ICP socket instead of a Unix Domain socket?

By far the BEST Video

Thanks 😊

Very well explained. Thank you so much!

bind(), listen() and accept() looks similar, what are the cases they're not used together?

Thanks, Im looking for multiplexes, reading about it because my touchpad laptop is not working and seems kernel multiplex is root cause. :D, nice video, way you explain is awesome. Do you post your videos for free or has paid content as well?

By Far the Best Explanation Ever for Socket File Descriptor in UNIX...❤️❤️

Great video, I really like the analogies it helps a lot !

Which book are you referring for all these quality videos?
