I started the month writing about long-lived systems

• Long-lived Computational Systems
• Gerry Sussman on Biological Systems

But mostly, I wrote about how I think about personal finance:

• The Day I Learned About Personal Finance
• My Second Lesson in Personal Finance
• My Third Lesson in Personal Finance: Optionality

The first post is about savings rate, so I made a spreadsheet and python script to help understand the effect I was describing

• Very Simple Net Worth Estimator
• The Net Worth Spreadsheet Documentation
• The Net Worth Spreadsheet in Vanilla Python
• Adding Market Data to the Net Worth Spreadsheet
• Using Market Data in the Python Net Worth Estimator
• How I Used the Net Worth Estimator

The second lesson was about increasing income, and I wrote two posts following up on that

• How Programmers Can Beat the Market
• Beating the Market Addendum: Taxes

Finally, I wanted to say a few words about excessive saving

• The Downside of Saving

And, I continued releasing Podcast episodes about writing

• Write While True Episode 8: Lower the Bar
• Write While True Episode 9: Deprivation
• Write While True Episode 10: Finding My Why
• Write While True Episode 11: Quantity and Quality

I’m doing a lot with SpriteKit and making tutorials on App-o-Mat as I go.
