*Micropython on ESP32 - Pravin Raghul*
Micro python is both space and compute optimized equivalent of cpython
interpreter that can be used in embedded devices.
Micro Python aims to bridge the gap for providing python programmability to
embedded devices which are typically resource constrained.

Speaker used minicom program to login to the ESP board.
Adafruit ampy is used to execute python modules on ESP32
Precompiling python module with mpy-cross tool will help in boosting
performance while lowering footprint in RAM of the device.
Some of the other techniques to achieve perf boost by use of native code
emitter, viper code emitter were explained.

*Tiny MLOPs - Soham Chatterjee*
Challenges in running ML at edge devices in IOT environment.
How things are done TinyML world compared to ML at datacenter servers
MLOPS stands for Machine Learning + Operations which deals with the
discipline of deploying, monitoring and maintaining ML pipelines in edge
devices.

How to identify elements from screen using openCV framework.
OCR is used to identify the captions on the UI elements.
Demo of automated testing of graphical calculator app.
Problems faced in OCR library for reading single characters as OCR
softwares are usually programmed to read large texts

*API testing with jmeter - Thangaselvi*
Talked about Apache Jmeter, Pros and Cons of using this tool for
performance testing
Demoed accessing google.com page with Jmeter
Jmeter tool has options to add pre-processor and post processor steps to
perform certain useful functions
