The 80/20 rule, or Pareto principle, can be applied to DAU (Daily Active Users) to explain user behavior. It means that around 80% of the activity on the platform might be driven by just 20% of the users. This helps us identify the most engaged users and focus on features or improvements that cater to them, ensuring that the majority of the value comes from the efforts targeting this highly active user group.

@@GeekySanjay don't think it would be applicable for messaging platforms, it's more suitable for photo sharing or content sharing platforms like RUclips , linkedin , instagram, twitter etc

The 80/20 rule can still apply to messaging platforms like WhatsApp. While 20% of users actively send most messages or share content, 80% might only read or respond occasionally. It’s just a different type of 'content' compared to platforms like Instagram or RUclips where we can apply 80/20/1 in social media

@@GeekySanjay respectfully disagree , i still feel whatsapp/ messaging systems are both read and write heavy, anyways it depends on the interviewers.

Glad it was helpful!

Thank you for your comment. You are right, a live interview would be more helpful. However, I made this video to assist others in preparing for interviews, and I simply want to avoid copyright issues by sharing the original video but i will try othor solution to avoid it.

Great suggestion! I am also thinking the same. soon i will share a video on it.

Sure thing!. i will create soon

No, it is not necessary to add a website to obtain the payment key. As you can see, I developed it locally only.

@@GeekySanjay When I try to get those API keys, it asks me website, even in the test mode I'm not able to get those keys. I raised help request they told me add a website to get those keys.

you can use localhost or 127.0.0.1 to refer to your local machine

@@GeekySanjay I tried that too , but they are rejecting it while verifying the website

@@udhaya8489 let's connect on gmeet I want to see what is the issue

Glad it helped!

Yes, you are correct. It was added incorrectly. It should be a many-to-many (M:M) relationship. To handle this, you can create an additional table, GroupExpense, with the following columns: group_expense_id, group_id, and expense_id.

Hi Varun, Thanks for the suggestion. I already added the index in Google Docs, but the outlines are not being exported when I save it as a PDF. I'm trying to figure this out as soon as possible.

You are welcome. Keep watching.

I'm glad to hear that you found the tutorial helpful! Regarding the error message you're encountering, "the id provided does not exist, BAD REQUEST," it may be related to Regarding the issue of Visa test cards not working with the Razorpay test environment, it's a common problem faced by developers. Please attempt using the test card number "4718 6091 0820 4366" and inform me of the results. If you encounter any further issues, please share your Git repository with me at shubh24i@gmail.com

@@GeekySanjay hello Sanjay. Actually the error got resolved, not by using the test cards, but using the real cards number, with random cvv and expiry dates. That trick worked. Even the other payment modes started working then. Thanks for response anyways!
