Many of these depends on your traffic, but some ideas I've seen:

- Sell weekly/monthly sponsorships directly (https://daringfireball.net).

- Write an ebook about a topic you are an expert in.

- Curated job posts if you are blogging about a niche.

- Affiliate links for products / services.

I'm not sure regular display ads would work well for a tech audience just because of the amount of ad blockers you'll encounter.
