1. PyMOTW 3 - Performance Analysis

• Python 3 Module of the Week (PyMOTW 3)
• Written by Doug Hellmann; same format as PyMOTW but now focused on Python 3
• Recently covered profiling / performance analysis with profile, cProfile, and pstats
  • Python 2 - https://pymotw.com/2/profile/

3. On Python being slow

• Yes, Python is Slow, and I Don’t Care – Hacker Noon
• You can write code faster more quickly in Python and developer time is more expensive than CPU time
• Python is usually not the bottleneck, but when things are slow you have options (profile, optimize, swap interpreter, etc)

4. Hashing

• A Quick Introduction: Hashing – Hacker Noon
• Fingerprinting static content for caching on the web

5. Wedding automation

• Wedding at Scale: How I Used Twilio, Python and Google to Automate My Wedding
