Boyer-Moore Voting Algorithm: If you have a stream of data and you wish to find element that occurs the most in constant space.

Many applications of this can be found in real world: Voting systems, Stream processing, etc.

As IIT goes international, it reminds me of Raghuram Rajan's 2006 interview with Shekhar Gupta.

@visvishwa_ That's right, because of such things I prefer and suggest to use `for` loops where possible.

[solodynamo @solodynamo]

`range` in Go can be tricky; prefer `for` always.

Code review excerpt:

```go
nums := []int{1, 2, 3, 4}
for _, num := range nums[1:] {
print(num)
}
// prints 1 2 3
```
It is so easy to overlook this but there is a reason we have code reviews.

Does anyone know whether a similar service to the one provided by https://t.co/VRG8QP6EMA, which reveals the last transaction price and the per square foot price for properties, exists for the Delhi NCR region?

IMO quite valuable to not trust brokers and over pay in the process

@Franc0Fernand0 BFS can also be applied to achieve topological sorting.

@icgee Some points to add:
1. We can still pay by cash in buses, you enter drop location, put your notes in a machine and spare change comes out with a ticket.

2. If not credit/debit card, there is EZ-link card which can be used for commuting.

3. There r officers who inspect tickets.

@debarghya_das Another thing, Apple Pay works offline. They store your credentials on your device chip unlike gpay.

KKR in IPL is lot like us as investors. We buy stocks, don't understand their value, cash out when we feel its the high.
My case: $NVDA
KKR: Pat Cummins, Suryakumar Yadav, Glenn Maxwell, and Shubman Gill

In India, if someone forgets their PAN card number without linking it anywhere, there is no way to know about it!!
You have to go through some brokers to retrieve it and pay a lot in the process. 😕
Bonus: pan card is needed in insurance, so you cannot even live peacefully!

DynamoDB: UpdateItem will still consume the full amount of provisioned throughput (the larger of the "before" and "after" item sizes).
This is quite dumb on AWS side or I am missing something.
Just call it Upsert if WCUs are same. Why have UpdateItem and PutItem as separate fn😐

Mom: "India" is being renamed to "Bharat"?
Me: Hmm, I'm not sure.
Mom: Will we have to go through another currency exchange process? Our bank notes have the name "India" on them.
Me: 😆

Shared my version of the domain takeover security vulnerability with my team Featuring Jack and Elon. 🔥

Teaching using real world characters sticks.

Catchy title but it's basically "siloing" within an AZ and handling AZs failover. But informative and something very important for resiliency. Hope to practically implement this and play around.

@solodynamo FYI. We are working on providing a more straight forward request number metric.

Playing around with AWS AppSync. It tracks total no of requests metric with name "4XXError". Took me hours to find such basic metric 😆

PII method detection API in GCP is called "Cloud Data Loss Prevention (DLP) API". Who said naming is solved problem in Software Engineering?

[solodynamo @solodynamo]

It's good to have light jokes during an incident.

Engineer 1: Someone suggested DB is the issue. We need to spin up a new DB cluster.

Engineer2: Are we sure its DB? suggesting is 1 thing, showing is another, I just want to make sure we aren’t going full-speed in neutral 🤣
