Hackerschool Week 4: Intro to Shell & Vim

🗓️ Tuesday, 3 February 6.30pm
📍 SR13 @ COM3-01-22
🧁 Refreshments will be served!

Shell and Vim are two essential tools for working efficiently in a Unix-based environment (and both are commonly encountered by 2030s students!)

We’ll start with an introduction to the shell, covering basic navigation, file management, and common commands to help you get comfortable working in a terminal.

After that, we’ll move on to an introduction to Vim, where you’ll learn core concepts, essential keybindings, and tips to make editing code and text less intimidating (and more productive).

Beginners welcome!

Keeping State Straight in Distributed Systems

At Jane Street, we rely heavily on inter-process communication and real-time message passing to drive many of our most critical systems, including those that ingest market data and implement trading strategies.

As we scale up the number of components, however, it becomes increasingly difficult to reason about the consistency and correctness of the overall system.

In this talk, we explore how transaction logs, state machine replication, and control flow inversion have allowed us to structure our applications in a way that lets us reliably deal with data races and process failures.

Speakers Profile🎙

Shi-Jie is currently a software engineer at Jane Street Singapore, attached to the International ETFs trading desk. He graduated as valedictorian with a double degree in Mathematics and Computer Science from NUS in 2017.

See you there! 👋
