Linux System Programming Techniques & अवधारणाओं

Linux System Programming Techniques & अवधारणाओं

कीमत: $19.99

There are already innumerable courses/tutorials on internet/Udemy which teaches almost every aspect of C programming language. All those courses sound same, talk same and deliver more or less same knowledge. How is this course different from others ?

The intention of this course is to make you ready for System programming Technical interviews, interview levelfrom Beginner to Intermediate. यह कोर्स के लिए है (भविष्य) डेवलपर्स, not for testers or System Administrators.

I choose to create this course to fill the gap between novice/beginner and intermediate/Advanced Programmers. This course assumes that you are at-least above average in programming (in any programming language, but preferable in C/C++) – know memory allocations, all kinds of loops, function calls, pointers etc. इस कोर्स में, I won’t teach C/C++ (there are already many courses on it online), but would teach programming techniques and low-level details regarding how C program works behind the scenesAll topics very important from interview point of view. My Target is to grow this course into Linux/C Bible.

अभी तक, I always feel, you need to outsmart your fellow colleagues in this era of stiff competition, और इसलिए, I tried this attempt to present you the wisdom and knowledge which is of utmost importance for a programmer. I have seen though students could write good C/C++ programs, yet they lack the clarity on how one should write better organized, Manageable, extensible and programmable codes in the form of libraries. उदाहरण के लिए, Students too good in competitive programming, yet do not know how to write a simple Makefile, reason being, Academics do not teach and students do not care to learn.

इस कोर्स में, I will cover the topics related to creating Linux System Libraries (रिहाई 1) with Advanced language-agnostic Programming Concepts (रिहाई 2) which can be well applied if you happen to become a programmer in other languages tomorrow.

The Concepts like बहु सूत्रण, Thread-Synchronization, Socket Programming, IPCs etc demands a separate course on each topic altogether. वर्तमान में, I have a course on IPC, pls check it out. These topics are out of scope for this course.

The Course shall be delivered into two Releases :

Release 1 Building and Managing a Library: This covers basics regarding how one should create and organize his code as a Library.

Release 2 Memory Management Concepts: This covers Advance concepts on Linux Memory Management specifically. Please check Table of Contents for more info.

Why you should *NOT* do this course?

1. Please Excuse this course if you are the ultimate beginner in C programming !!

2. There is no point of doing this course if you don’t like hitting the keyboard, and lazy enough to watch lecture VDOs only

3. If you want everything cooked and served on your plate.

Course Pre-requisite :

  • Above Beginners Level in C/C++ programming

  • Good to have basic OS knowledge

  • Zeal to excel and Code

कोई तृतीय पक्ष पुस्तकालय नहीं

आप जो भी तर्क लागू करते हैं, आपको इसे स्क्रैच से लागू करने की आवश्यकता है. Like all my other courses, this course do not suggest taking help of any third party library to get the jobs done. बाहरी पुस्तकालयों का उपयोग पाठ्यक्रम के उद्देश्य को पूरी तरह से पराजित करता है.

चेतावनी: This course has auto system-generated subtitles which may not be perfect. Please disable subtitles as per your convenience.

क्यू. What are the frequently asked questions by interviewers in a technical round when someone writes C/C++/System Programming language on their resume?

उत्तर : If i am interviewer, what questions i would ask depends on his no of years of experience in C.

1–3 yrs of experience — I would have asked:

  1. Double pointers

  2. design a Macro to return the size of the structure

  3. Two Dimensional Arrays, passing and returning arrays from a fn

  4. Different stages of C program compilation

  5. how fork() works

  6. What are various ways to debug memory corruptions.

  7. various IPCs

  8. Heap and Stack memory-based Question

4–6 yrs of experienceI would have asked:

  1. How memory is allocated by the OS

  2. Internal and external fragmentation, what can be done to avoid it

  3. System calls, strace()

  4. Trade-of of one IPC over other

  5. various ways to communicate with kernel and comparison

  11. Thread Synchronization

  12. Heap and Stack memory based Question

7+ yrs of experienceI would have asked

  1. Have you designed any system module to solve any problem

  2. Design thread library 0 what functionalities would you incorporate in and how ?

  3. What are Dos and Dont’s for writing a robust and flexible library

  4. How to write generic code in C

  5. Various ways to implement timers in C, and comparison of approaches

  6. How Interrupts work ?

  7. IPCs and comparison

  8. How would you convert a C code to C++ and vice versa

  9. How to write a tool to detect memory leaks, Or garbage collection

  10. Design your own memory allocation tool. Why would you write your own memory allocation scheme ?

  11. When to go for Multi-process design over Multi-threaded design and vice versa

  12. How ValGrind tool works

If you analyze the pattern,

Candidate with 1–3 yrs of experience, I would chose to ask more of a direct and straightforward Questions.

Candidate with 4–6 yrs of experience, I would chose to ask more advanced technical C Question plus some comparison of approaches based Questions

Candidate with 7+ yrs of experience, I would chose to ask more of a design and Analysis based Question.

ध्यान दें कि, since Question pertains to C and System Programming, so i have not mentioned Data structures and Algorithms.
