mtlynch.io

• Wrote “Get xkcd Cartoons at 2x Resolution”

Refactoring English

• Worked with two freelance blog editing clients.
• Continued working on “The Software Essays that Shaped Me”
• Worked on setting up custom emails to customers after they purchase.
  • This is surprisingly hard with Stripe purchase links!
  • The only way I could figure out how to do it was to spin up a server running custom code and point to it from Stripe’s webhooks.
• Doubled my prices for freelance editing
  • Single blog post: $200 -> $400
  • High-level review: $250 -> $500
  • I feel like I’ve learned what I need from freelance clients, so I’m trying to reduce the number I take on.
  • I’m planning to offer some deal like you get an 80% discount if you finish the book, so I can see how well people learn from the book.

streamablize

• Support ad-hoc trimming the start/end of a video

zarchiver

zarchiver is a file archiving tool I’m writing to practice Zig. It’s basically me implementing my own zip file format.

• Serialized the file signature
• Added a file format version
• Implemented a mock implementation of std.Io.Random

Misc

• Suggested unit tests for the Roku Jellyfin client
• Visited friends in NJ
