Something that interested me this week

I finished up Blogvent where I write everyday with this post about styling markdown blockquotes, and this one about making a "nature documentary" about a developer at the end of the year. I also posted this about the GitHub Podcast, too. You can check out my Blogvent wrap-up post as well to see all of them from this month!

I'm personally pretty cool with 2025 ending. It was a year of big ups (I had a baby!) and big downs (personal things, the state of the world, etc etc etc), and... I'll probably blog about it. I'm ready for a new year.

All this being said, thank you for reading this newsletter and being a part of this little corner on the internet. It makes my day when I hear people actually read my words, genuinely, and I'm grateful for you!

I WILL SEE YOU NEXT YEAR! Heheheheheh.
