In this video, Harkirat takes you through some advanced Backend concepts.
Specifically, he dives deep into the Websocket protocol and how it is used in real time communication
Well, what a coincidence, I today made a socket related program in python and I was reading about it and your video came up. NICE!
You really teach me to get out of the tutorial hell and how to Stop comparing yourself with others and everything that a person needs to become a humble and kind person thanks harkirat to play an important role in changing my mind set❤❤
Did you join the course already
@@shuaibushehu6205Nope
That "i apologize for white screen" was personal.😂😂
Everytime I am watching new videos, you are increasing my confidence and also increasing my interest towards you and cohort 2..
Egarly waiting for the first class....
do you purchse it ?
Brother, you're amazing,, keep teaching❤ thank you🙏
I bought the course
Nd so pumped up
Harkirat, Server-Sent Events (SSE) is not an inferior or obsolete technology; in fact, we actively utilize it in our project. The key distinction between SSE and WebSockets lies in their communication nature. While WebSockets enable bidirectional communication, allowing data to flow both ways between the client and server, SSE operates unidirectionally. In SSE, only the server can push data to the client.
Additionally, there's an important aspect of WebRTC that you didn't cover. In WebRTC, we can establish a server just to facilitate connections among clients. Once this initial setup is complete, the server's role can be diminished, and clients can continue communicating directly. This means that after the WebRTC server has fulfilled its purpose, it can be removed from the communication path while clients maintain seamless interaction. This highlights the flexibility and efficiency of WebRTC, allowing for direct Peer-2-Peer communication without the need for intermediation. We use it extensively in our IOT projects.
Just purchased the 0-100 cohort, was speculating a lot but did the right thing ig. Hope to be there, attending meetings from office throughout the world!
when is the cohort going to start
@@onkarsathe4102nd Dec 2023
Sir, as you said that classes will be 2 days a week (i.e) 24 days in 3 months for 0-1 course, is this number of days is enough to teach or you will also upload offline videos(recorded videos other that live recording)...?
This video was so eye-opening, thank you for sharing.
Hi Harkirat,
as you have shared the roadmap to full stack , can you share the same for the AI as well?
Hello Harkirat, is it okay to authenticate the user with each message, or is it sufficient to do so when the socket connection is initially established in a chat application?
Nice

Hey I was planning to buy the 0 -100 cohort but im confused as to how the lectures would commence because you seem to have given three options and you cannot teach live simultaneously. So can someone please help explain how the classes will take place and at what time?
Dude just look at the timings... 0-1 will be for the first 3 months and 1-100 for the next two months
Is two day a week enough to master the techno..?
Please keep course price discount for 3-4 days more. My payment got stuck in process which will be refunded in 2-3 days

Bhaiya what will be the duration of the full course 0-100? Please answer🙏🏻
5-6 months
7 month

You can connect simply, he paas the localhost url on browser,
But I don't know why he use ws library instead of the socket io
@@gauravbathla8666 how can a server on the internet access my computer's localhost??
Cant buy the recorded version of 1st cohort?????
You can on the website
Hi, Harikat... I'm doing my graduation online on Data science. I'm in my first year and literally have zero idea on programming. I've taken the 0-100 devs course. Can i expect looking for part time jobs or freelancing if i manage to consistently learn and finish your course?
How is the course?
@@itzme1398 Hasn't started yet
@@novaorionis where are these videos coming from? I though they are part of the course
@@shuaibushehu6205 No. These videos are from previous cohort.
The cohort course is useless.
Atleast that's my point of view.
Arey Bhaiya, are you going to upload the entire season 1 gradually?... 2-3 videos were enough for the preview I guess!
Jealous if he uploads everything?
Bruh, this is just the 3rd video of the preview!
@@extremeweirdness1528send me the link bro

What if some hacker keep sending large number of dummy packets to my webSocket, due to which some client's packets amy keep dropping due to queue size? how this thing is checked!?
@harkirat1 ???
What a dumb question, first of all websocket uses tcp connection so no packets will be dropped and second thing every websocket connection is independent of each other so you can check if any connection is sending too many packets
i didnt knew that time that web sockets uses tcp protocol over network.@@yashsolanki3665
Are the classes live for cohort 2 ?
I want to be a part of it but I thought classes start from 2nd dec ?
Is this from cohort 1?
This is from cohort 1
Cohort 2 will be live

In the description its mentioned its an advance concept so how is this video a preview for the upcoming cohort ?? Is this preview for 0-1 or 1-100 joinees ???

Harkirat bhaiya, the cost of 3700 is too high for me to afford for the 1-100 cohort. Can you please consider lowering the price

If you already know 0-1 then you should know that it's considerably less. 0-1 is enough to land a job. Then you might be able to afford the rest.
