Talk Details

  • From Prompt to Production: GenAI and Python Functions for AWS Infrastructure by Suraj

    Suraj demonstrated how organizations can use Crossplane, a Kubernetes-native Infrastructure-as-Code (IaC) platform, to deploy artifacts directly to production. He compared a sample Terraform JSON configuration with its Crossplane YAML equivalent and showed how infrastructure changes—specifically updates to an AWS S3 bucket—can be managed through Crossplane. The workflow involved generating a pull request to GitHub, and upon approval, the changes were automatically propagated to production using ArgoCD.

  • Next-Gen CPython by Guru Vigneshwaran

    Guru guided the audience through the next-generation enhancements in CPython focusing on performance, concurrency and production operability. He explored how incremental garbage collection and a just-in-time (JIT) compiler are being introduced to reduce pause-times and boost throughput. He also covered annotation libraries (“Annotationlib”), multiple interpreter support and other runtime layers, along with zero-overhead debugging facilities and advanced async I/O introspection capabilities. Throughout the talk, both theoretical concepts and practical demonstrations were used to show how CPython’s internals are evolving to meet modern scalable use-cases.

  • Embedded Graphics & Game programming using OpenGL by Praveen

    Praveen explained the differences between CPU vs GPU workloads, various stages in graphics rendering pipeline and in OpenGL ES library in detail. OpenGL ES library is leveraged by the Embedded Systems, Computer and Mobile devices. He did a walkthrough of sample Python code and graphics definition in C program. He introduces the Vulkan, which is a next generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs used in PCs, consoles, mobile phones and embedded platforms. 3D Graphics Rendering Pipeline

  • HTTP3 QUIC by Rengaraj

    HTTP/3 is the latest evolution of the Hypertext Transfer Protocol, designed to improve the performance, reliability, and security of web communications. Unlike its predecessors that relied on TCP (Transmission Control Protocol), HTTP/3 is built on QUIC, a modern transport protocol developed by Google and standardized by the IETF. QUIC uses UDP (User Datagram Protocol) to enable faster connection establishment and reduced latency through features like 0-RTT handshakes and built-in encryption equivalent to TLS 1.3. It also addresses the “head-of-line blocking” issue seen in HTTP/2 by allowing multiple data streams to be delivered independently, ensuring that packet loss on one stream doesn’t delay others. As a result, HTTP/3 delivers smoother, faster web experiences, particularly useful for mobile networks and applications requiring real-time responsiveness.

  • Google AppScript by Arockiaraj

    Arockiaraj demonstrated an event management usecase where he automated meeting invite creation by populating the meeting date/time, meeting link, description and feedback document attachment automation by pulling the data from various Google spreadsheets and documents using AppScript.
