# Meeting Minutes May 2025 We started at 3:15 PM since we waited for people to join. We had around 30 attendees. We started with introductions; we had a lot of first-time attendees.
## First Talk ### Elasticsearch Madhav Kumar went in-depth into Elasticsearch internals. He explained various techniques used in search to tokenize words. He spoke about tokenizers and how they work: - N-gram - Edge N-gram He also ran some demos. ### Build, Dissect Packets Rengaraj started with an introduction to the Scapy framework. - He had a spelling mistake in the title. - He compared the OSI layer with Scapy APIs. - He went on to create IP layer packets. - He went on to explain how to stack layers of a packet: Eth/IP/UDP or TCP/DNS - He created packets and sent them over the network. ### Networking Tea Break Before the tea break, we called for volunteers to introduce themselves and share their areas of expertise to enable meaningful networking during the break. ### Optimizing Python: From Slow to Go Guru gave an excellent talk on how we can improve Python processing time when using: - Threads - Multiprocessing - Concurrency - asyncio - subinterpreters An important takeaway is that subinterpreters—something I had never heard of— have been in Python since version 1.5. ## Lightning Talks * Abhishek started by showing various AI model performances and left us with the question: when an AI model reaches 100% accuracy, what is going to happen? * Vijay gave a talk on Sentence Transformers, which he learned about while prototyping an AI-based voice control system (I think). - He showed how words are clustered. - He showed how sentences can be clustered. During Vijay's talk, I thought: it’s a steep learning curve. * Shreyas gave a talk on how he used AI as a partner rather than just a Q&A tool. He showed a structured one-page prompt designed so that AI asks questions instead of only responding to human prompts. This way, AI becomes a partner rather than a threat. # Thanks With that, the Chennaipy May meetup concluded. Rengaraj thanked: - All the volunteers behind the scenes - IMSc and Prof. Amirtanshu for the venue and continued support - All the speakers - The timekeeper We finally took a group photo. I saw a lot of people hadn't left the campus until 6 PM. They were discussing things all the way until they exited the gate.
