Hackers Toolbox: Command-Line Data Wrangling

🗓 Tuesday, 12 Sep, 6.30pm-8.30pm
📍 Seminar Room 15 @ SoC (COM3 01-25)

Sign up here!

Machine Learning, AI, ChatGPT, Data Visualisation - these latest trends are all powered by a single entity: Data. But in order to get there, we need to first learn how we can obtain data that makes sense to us.

In this week’s session, we will be learning how we can clean, organise and transform raw data into a structured and usable format, all through the Unix command line. On top of that, we will see how data wrangling is employed in Visa 🤩, offering a glimpse into its real-world application within an industry system. 

Please ensure you have access to a POSIX-compatible shell, such as Bash.
If you are on macOS or a Linux distribution, you are set;
if you use Windows, consider installing Windows Subsystem for Linux (WSL) or Ubuntu in VirtualBox.

1) From an Idea to a Product: How I Made My First Indie App
Have you thought of building your product before? Like many mobile developers, my first app was a weather app, built when I was a sophomore-student, but it’s probably pretty different from the one you use.

I will share some stories about my different roles in projects, and my continued love for making indie products.

2) From Zero to Thousands: Building a Tech Startup for DevOps and SREs and Joining Grafana
Learn the journey of building a tech startup for modern Incident Response Management, and how it eventually became part of Grafana Labs: an industry-leading observability company with millions of users. Discover the technologies chosen, challenges faced, and the stages of growth, to thousands of users.

Online Algorithms Made Easy
The world around us is constantly changing and at Jane Street we're receiving new data at a rate faster than ever before. When running complicated models that contain many parameters, reacting to a change in a single parameter by restarting the entire model is impractical. Jane Street makes use of ideas from research into self-adjusting computation in order to turn static models into models that can be partially recomputed in an efficient way. This talk will introduce self-adjusting computations and show how it can be used to make online algorithms easy to run and update efficiently.

Lester Tan is a software engineer at Jane Street. He graduated with a degree in Computer Science from NUS, and is currently working in the Singapore office.
