ChatGPT's Advanced Data Analysis and Code Execution - Experiments

Recently, I learned that ChatGPT now allows advanced data analysis, which includes executing code (Python or possibly others). This feature is available to registered users via GPT-4o, albeit with limitations.

I quickly tried running system commands using this functionality, and here are the results:

It clearly shows that system commands can be executed through Python code in a sandboxed environment.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

Hi:

perl -e 'print "hello world!\n"'

A simple filter:

perl -ne 'print if /REGEX/'
