Course Overview
Data Structure & Algorithm to Schedule future events, Linux System Programming, Operating systems, C/C++ programming
O Ghosh !! I just cannot shout-out more how important TIMERS are in almost all applications or projects. Timers are used to schedule events to be triggered or fired in future. How have you been doing this till now ?
Timers Use case Scenarios :
1. Firing One time future Event : Delete something after 100 seconds
2. Firing Repeated Regular future Events : Send packet to machine X after every 5 seconds
3. Periodic Waits : Try something 5 times at an interval of 3 seconds
How would you design a timer ? PET Question for interview. So better prepare for it.
About this Course This is short project based course, yet important course to cover Data Structures and Algorithms involved in designing efficient timers. We shall be using C as a programming language, but you are free to use your favorite programming language. This course is Programming language agnostic.
Course Pre-requisite
If you can code in any programming language, that suffice.
You should familiar with basic data structures such as linked list and function pointers.
Basics of Multi-threading
Also, Please just do not sit and watch my codes. Write your own codes, even if it is same as mine !
No Third Party libraries
Whatever logic you implement, you need to implement it from scratch. This course do not suggest taking help of any third party library to get the jobs done. Use of external libraries completely defeats the purpose of the course. However, it is recommended to use third party libraries for commonly used data structures such as linked lists/Trees/Queues etc which saves a lot of time implementing these data structures.

As expected, added timer API into my learning space. Thank you, Abhishek Sir.

This course thus far has reinforced my understanding of Posix Timers, and made me aware of the Exponential Backoff type timers. I am pleased to also now be learning material new to me relating to a design that is scalable to a very large number of events, in which each timed event does not require its own timer thread, which cannot scale on a single machine which naturally has limits on the total number of threads that can be running simultaneously.
