My repo of Today I Learned posts. Inspired by simonw/til.
Now: July 2024: At some point this month, I set a goal to write a TIL every work day. I haven't stuck to that, but I am averaging several per week, and I'm pleased with the cadence. But even trying to post every day, I am still not capturing everything I've learned.
Since this repo has a few stars ⭐ (hi everyone), I want to take a moment to set expectations.
- I write TILs quickly, usually in under 10 minutes.
- Usually, there isn't any editing other than light proofreading.
- I really enjoy it! Highly recommend a public TIL repo as a personal practice.
- Sometimes I share them on Mastodon, but not always.
- It's good, low-stakes writing practice.
- It helps remind me that beginnerhood is perpetual.
- I have a few of my own TILs that I consult really regularly. Nothing beats copying and pasting your own stuff forever.
- Sometimes, the TILs get picked up by Django News, and that's neat!
- Other people are aware of what I am working on, and then ask for help related to those things. Feels great to help people.
- It provides a neat fossil record of the kinds of things I've worked on over the course of my career.
- I have a repo full of markdown that's easy to clone and run parsing experiments on.
