13 min - Day 59: CodingEveryDamnDay. Working with... Swift Playgrounds, Learn to Code 2, Coda, Harry.
Discussion:
- Writing code is a complex problem solving process that needs to be exercised as often as possible.
- I’m going to implement a new habit of writing or modifying at least 1 line of code every day.
- I expect this will not be as straightforward as it sounds.
- Will likely require reading a decent amount of code first as a pre-requisite to making any modifications.
Progress Update:
- Crafting the leaderboard in Coda
- Video editing workflow set up
- Re-organising the Handstander Project in Coda - ticking off all the old questions and tasks.

9 min - Day 51: I am now a subject domain expert in a very specific niche. Working with... Taking some down-time.
Discussion:
- Talking to Felix, an experienced ML programmer who has worked in robotics, I realised I am no longer a beginner when it comes to training AI models, and I am approaching expertise when it comes to training an action classifier for an iOS app.
Progress Update:
- Completed a data set for ideal handstand conditions of just over 20 videos. Tested the model in ideal scenarios, and it performs decently well on all of them. It’s probably time to build the logic layer now and implement that into the app for further testing.
- Developer program still pending.
- Learned that apps auto delete themselves from your phone after 7 days if you have not paid for the developer program.
