Great Talk

Best talk of rubyconf 2024

How would you scale redis in this case?

Learning experience for the next year - will try not to turn my head back too much XD Awesome vid btw!

Please explain at 27:45 why is GRPC more advanced give us stats what part of GRPC indeed were helpful for your use-case (was it multiplexing ?)

I previously built a similar system but never gave it a formal name. In my implementation, I had numerous delivery fleet members continuously publishing their geo-coordinates. The admin panel needed to live-track these fleet members within specific radius boundaries. For instance, an operator working from Financial District, Hyderabad, would only see fleet members within their designated 3km radius and could assign tasks accordingly (with additional proprietary features). Initially, I established WebSocket connections between the admin frontend and the fleet tracking microservice to receive real-time geo-location updates. However, scaling challenges emerged when the admin frontend microservice needed to connect to multiple fleet tracking backend services simultaneously. The key challenge was determining how each fleet tracking microservice would know which geo-coordinate updates to send to which frontend client. I resolved this by implementing a Kafka queue system where geo-coordinates were published, and the respective fleet tracking microservices would subscribe only to the selected driver's coordinates as chosen by the frontend. While I didn't formalize this into an open-source standard, it's satisfying to see that I solved a similar architectural challenge about two years ago.

Doesn't having more Redis Nodes slow down Pub Sub ?

I made a mistake with MongoDB. Phil Eaton pointed it out that the default write concern "majority" actually implies "j: true" which means data is synchronized (i.e. fsync-ed) before returning a success to a client.

Very informative session for a Rails developer. Thank you

Great talk

Great session 👍👍👍

the issue is not exclusive to go, unsafe concurrency is feature of every language i know of except rust. that's one of rust's selling points

Thank you for putting it together and posting it here. Fantastic presentation. I find knowing the historical context immensely helpful when trying to understand the current way of doing things, e.g. jsbundling-rails, cssbundling-rails, or importmaps in 2024 (and something else in 2028), so I really appreciate this.

Great speech

Bar far the most wonderful and informative video I've watched through months. Each sentence was conveying lots of useful and valuable information. Thank you!

*promo sm*

Lots to improve upon, but a good start nonetheless, if I do say so myself.

Very nice speech Niharika 👍

Really great. I am proud of you.

Cool ... nice stuff Shri

Keep।it up😊

This is an added value for a software engineer who have more skills on Formal Method with using proof assistant programming language such as Coq, Agda, Isabelle HOL, Lean, Idris, etc. or formal specification language such as TLA+, Dafny, Alloy, F#, Z3, etc. Thanks a lot for this great presentation.

What a great introduction to formal specifications and how you can use it with Go! Really loved how to explained the deadlock example <3

Amazing presentation

Wonderful. Raghav .God bless you.❤🎉
