I'm beyond excited for this - meet your heroes! Come meet mine! @jorandirkgreef and team's docs about their philosophy of engineering resonated a lot with me, a lighthouse of inspiration and rigor amidst a storm of "good enough" - I can't wait to learn, again, in-person!

Bengaluru Systems will be hosting Team @TigerBeetleDB for the Bengaluru leg of the 1000x World Tour! Come hang out with us on 6th December and learn from some of the most amazing, category-defining Engineers we know - @jorandirkgreef, @amodm, and @chaitybhandari 🚀see you there!



This is the first major release I've been a part of @couchbase - super pumped to see it go live!

Couchbase’s breakthrough vector technology delivers billion-scale performance with high recall accuracy and millisecond latency. With the introduction of three distinct vector indexing and retrieval capabilities that support a variety of diverse vector workloads, Couchbase 8.0…

This sounds like such a fun, learning-rich course - wish I had the chance to do something like this during my undergrad!

This is how I was taught C++ at ITMO University: 1. Implement my own 'printf' in pure Assembly 2. Implement Big Integer class with CoW and SOO 3. Implement the QuickHull algorithm 4. Learn Type Erasure and implement my own std::function 5. Implement Persistent Binary Search Tree…



Be there!

The CFP for our 12th meetup (happening this saturday - 27th September, IRL) is open - we are also looking for a venue, so please reach out if you would like to host Bengaluru Systems! hasgeek.com/bengalurusyste…



Congratulations to everyone @useblacksmith!!! Y'all are doing some really cool stuff.

We’ve raised our $10M Series A, led by Google Ventures. Meet Blacksmith.



Go @PrathameshD_8 🔥 Can't wait to see what you end up building

1/ Prathamesh (@PrathameshD_8) is interested in AI safety and has worked on adversarial ML and distributed systems. Over the next 6 weeks, he’s building a language model for Tulu, a low-resource language with sparse data and an ancient script spoken by 15–20 lakh people.

It makes me so happy that we get to spread awareness about such awesome work being done to empower women and girls by @Aarti_for_Girls, via our platform at Bengaluru Systems - big ups to @MadhavJivrajani for making this happen, what a wonderful way to get the word out!

We tried to do something a little different for swag in this edition of the meetup. While we usually have stickers, this time we also had these wonderful tote bags with our logo on them, created by the amazingly skilled artisans at @Aarti_for_Girls.

This was so much fun!

We had our previous meetup on the 6th of September 2025 at the @Razorpay office in Koramangala. Here's a small breakdown of all the lightning talks that happened - including but not limited to, io_uring, talking about why @TigerBeetleDB is so cool, Nix, Torrents, and Raft 👇

Important to note that this can happen between two close layers of abstraction too (i.e. benchmark harness and service, testing framework and code, etc) It's very important to take a close look under the hood to realize what's going on!

Tomorrow's meetup will be at the @Razorpay office in Koramangala, where we'll be bringing back our beloved Lightning Talk format ⚡️ More details here - hasgeek.com/bengalurusyste… See you folks tomorrow - let's discuss systems!


Live on the @BengaluruSys discord today: @MOVNTDQ walks us through how LiquidCache (VLDB 2026) - a pushdown cache on object storage systems for cloud-native OLAP workloads - works, and why object storage is the future of next-generation workloads and databases.

Ok, well it's a good thing I posted because this makes so much more sense - look at the hot gas just above the tail of the booster.
