Intro to bash
Bash (Bourne Again SHell) is a widely-used Unix shell and command language that enables efficient interaction with the operating system through scripting and command-line interfaces. It allows users to automate tasks, manage files and processes, and execute system commands seamlessly. Bash provides a rich set of features for scripting and automation, including file manipulation, process control, text processing, and system integration, making it a foundational tool for developers, system administrators, and power users across a wide range of environments.
Time: 04:50 PM - 06:00 PM
Into to Ngnix
Nginx is an open-source web server software known for its high performance and efficiency. It is used on websites to handle server load and as a reverse proxy. In this session, we will cover how Nginx works.
Time: 04:50 PM - 06:00 PM
Intro to Control System
A control system governs and directs the behaviour of devices or processes through control loops. Its scope ranges from a residential thermostat regulating a fan to complex industrial systems that monitor and control machinery and large‑scale processes. In this session, we will be looking into the overview of what is control system is and its potential applications.
Time: 04:50 PM - 06:00 PM
Introduction to PID Controller
A PID (Proportional-Integral-Derivative) controller is one of the most fundamental and widely used components in control systems. It continuously calculates an error value and applies corrections to bring the system to the desired state. From balancing robots to cruise control in vehicles, PID controllers are everywhere. In this session, we will explore the basic structure of a PID controller, understand the role of each term, and discuss its practical applications in real-world systems. This talk aims to provide a beginner-friendly overview of how PID control works and why it's so effective in both simple and complex automation tasks.
Time: 04:50 PM - 06:00 PM

Time: 04:00 PM - 05:00 PM
Room Cooling Systems (ACs) Optimization
Abstract:
The presentation covered the evolution and optimization of the CSE@IITB server room cooling systems, highlighting challenges and solutions. It detailed the historical timeline. Issues like overcooling, condensation damage to high-value servers, and unstable temperature control were discussed, along with system failures due to poor maintenance, muddy chilled water, and actuator malfunctions. To address these problems, a custom-built control system using Linux, ESP32 microcontrollers, and PID-based regulation was implemented, improving stability. Future plans include better humidity control, direct PCIe-based I2C communication, and improved power monitoring integration for enhanced efficiency.

Are computer systems secure?
Abstract:
Computer architecture breakthroughs over the past two decades have revolutionized how computer performance is measured. Caching, out-of-order execution, and speculative execution have been integrated into almost every modern processor, speeding up computers beyond imagination. The very same ideas and philosophies, however, have opened up new avenues for wholly different classes of vulnerabilities. In this talk, we shall consider the coupling of performance gain and security damage. We will take a close look at how microarchitectural features expose systems to side-channel attacks. Techniques such as Flush+Reload and Spectre that exploit design flaws to retrieve sensitive information from victim processes will be discussed. Through examining the vulnerabilities and their exploitation, we will learn about the performance-security trade-off and the efforts made in this dimension towards building a secure system.
