Linux System Programming Techniques & Concepts (Udemy.com)

The course content is very easy to follow. I learned about how malloc and free functions work under the hood, which was always a mystery to me. The theoretical knowledge about stack, heap and virtual memory, blowed my mind. I had no idea about this even though I have been coding in c for so long. The course really made me intreseted in linux OS and now I am venturing into other topics related to this. Overall this course will take you a level above in programming and you will get to understand the working of C on linux OS.

(1) The coding style the instructor adopt is kinda weird and quite different from K&R style. (2) I don't think iterative macro (or iterator macro) is something worth mentioning. In addition, it's confusing. There's almost no info on this if you google it and the most recent thread discussing this on Stackoverflow is about 10 years ago. (3) And the course would be better if the accent of the instructor could improve.

so good so far , you must be aware of data structure before enrolling in this course , you will learn a lot of techniques for me he made his promise to take my programing skill to the next step and that what happen with me , so thank you Abhishek for your effort and to make such great courses available to us. i already purchased all of his courses, meet you in the next course , heap memory manager while(Abhishek){ courses->next; }

The instructor was very good at simply explaining low-level topics. Most of the assignments were well-thought-out, but a couple in the paging section could have used some more examples to teach the procedures on calculating memory size. Overall a great course for intermediate programmers already familiar with the C programming language that want to learn more about Linux.

Yet another incredible course by CSEPracticals. The instructor's knowledge is *vast* - definitely my favorite instructor on Udemy now. Seriously, if you want to understand how C and programming in general works under the hood, take this course. I really enjoyed that this course was more theory-heavy than the others. Lots of valuable information such as how malloc / calloc / realloc and heap memory works, how memory mapping and paging works, 36 bit vs 64 bit, etc. The theory is accompanied by tons of analogies, illustrations, and examples along the way. There's a LOT of information in here that you will absolutely need to know for interviews and professional software development. Excellent stuff!

Thanks for offering this course, got a better understanding over programming concepts and memory management. In demand paging, you mentioned CPU will locate the swapped out page, could you add how it will adding? In Multithreaded process you mentioned about stack, what does the stack pointer points to since it has to manage process's stack as well as thread stack

When I started this course I was skeptical about the ability to explain all the topics that are listed in the Course Content. But, I changed my mind after a while. Yes, this course might suffer from, let's say, low quality slides and pure sound but if you follow instructor carefully you we see that the value of the course is the information and the simple explanation of a quite "hard to understand" topics. I've had some background in OS area before I started this course and wanted to brush up my knowlege, and must say I found lots of valuable things that filled the gaps I had in understanding the way OS processes works. It is actually can be applied to the Windows OS as well. Thank you guys!

El inglés no es mi primera lengua y aún así se puede seguir el curso sin problema: la dicción y el ritmo son impecables. No puedo aún valorar cómo se va a abordar por el profesor el salto conceptual que necesariamente se va a tener que producir entre los primeros módulos, más básicos, y el tratamiento de la memoria: memoria virtual-física, paginación, stack-heap. Será interesante.

A truly amazing course with a very deep dive into the Linux system. But it went to deep into memory management instead of covering other important aspects like package managers, pthreads, sockets and files/resource which would have been more suitable to this course and would have been helpful in creating some useful Linux application. Good Content... But some things could have been compromised like paging and other mentioned topics could have been explained along with a little project.

Great course with useful content. I completed all of this course before leaving a review and can recommend it for anybody interested in furthering their understanding of the internals of the Linux OS and C programming. I'm a native English speaker and didn't have any problems understanding the instructor. The explanations are clear and often covered from different angles to help your learning with good diagrams. There are also optional assignments to do as part of the course which I highly recommend to do. One thing to be aware of is I was following along with this course on a very recent 64bit Linux distro and what wasn't covered in the lectures were some of the optimisations that occur at the OS level. For example, I wrote a small c program and looked at how it looked and changed in memory - this didn't marry up with what I was seeing/learning in (albeit just a small section) the videos probably for 2 reasons. The first is most of the emphasis on this course refers to 32 bit OS's (though I'm not sure if there are any huge differences with what is covered in this course for 64 bit systems) and the second is it may have made the lessons too complex and is probably a whole course in itself. So I had to do a bit of googling around to help me understand what I was seeing. It's not meant as a negative point at all - just something to be aware of. I've also bought another course from this instructor which I am looking forward to starting.
