Try to limit your blogs to technical learnings, though we do not stop you from blogging on any other non-technical learnings as well.
You could blog about your learnings in Python, Machine Learning, Pandas, Vi, Linux, Cloud, or anything else that you are working with
Here are some suggestions for the categories you can blog about :
TIL (Today I Learnt)
Write atleast 4 to 5 lines about what new thing you learnt today
Give a scenario where it helped to add more value
Discovery
Your experience about something you tried on your own
Could be a do-it-yourself kit, or building up a setup on your own, or a mini-project work
Tutorial
Step wise details about a teaching a topic of your choice
You could write one chapter per week if required
Challenge
Use this blog to post your daily/weekly progress on the challenges you are pursuing
Example : 100 days of coding, 60 days of Pandas
That's awesome !!!
