MapReduce is one of the foundational paradigms of Big Data processing, pioneered by Google! In this blog post, I review the original paper, and add some diagrams to make it easy to understand! https://t.co/uTjW2haduD

What a fantastic day this has been - I got to host @jorandirkgreef and @chaitybhandari in namma bengaluru on behalf of @BengaluruSys, got to see the 1000x talk live, and learnt so, so, so much about life and engineering from @amodm, Joran, and Chaitanya :D thank you, folks!
Thank you @AnirudhRowjee @amodm and all our friends @BengaluruSys for having us in Bengaluru! And @chaitybhandari for flying halfway across the world to join me on tour. An incredibly special day. 1000x BLR!

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 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

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.

The whole point of this exercise was to be different, as the product really is something fantastically different- it's *supposed* to go against the grain and *not* be just another icon on your dock. You are *supposed* to stop and stare. Sad to see so many people missing the point

I loved this. we need to bring soul and character back to products. Such a refreshing tribute to the early days of the internet, and executed so, so well. Also the idea of model personalities (a la six thinking hats) - what a fantastic idea! Props to the folks at @areatechnology_
Brand exploration for OpenAI with Sam Altman, February 2023 Two logo concepts – Circle and Monogram – alongside broader exploration for ChatGPT across brand and product. More details and link below.

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!

You already have a good idea of what the output looks like Bonus points if you do it in a more systems-y language to learn it Scope for expansion is infinite

Writing your own SSG is one of the best gateway projects into systems Well scoped, you've already got a reference You'll learn 1. File IO (Direct/Buffered/Unbuffered) 2. In-memory indices (content tags, lists, etc) 3. Filesystem APIs 4. Parallelizing rendering per file 1/n
[WIP] Calling it Garlic (It's written in go + inspo from @AnirudhRowjee 's Saaru)

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.
