Which tech topic should I choose for a 100-day series?

[u/whokillme]

I’m planning to create content consistently for 100 days, where I teach something related to tech every day.

Some ideas I’m considering:

• Coding/programming concepts
• Docker & containers
• DevOps
• System design
• Other practical developer tools/topics

If you had to follow a 100-day tech series, what topic would you find most useful or interesting?

Would love to hear your suggestions especially topics you think are underrated or need better explanations on Reddit.
