Best affiliate program for Linux users?

I'm new to all this. I have a website where most of my content is Linux-related. So tutorials, distros, news etc. I already use AdSense. I've tried using networks like BuySellAds but there was little success. Most of my users are tech-savvy so they use AdBlockers or don't click on ads at all, so AdSense doesn't really work well.

I'm looking for affiliate programs that I can use throughout my site. So what affiliate programs would you recommend when your target audience are Linux users? This basically means very tech-savvy, interested in software, open source etc.

I'm already using some hosting affiliate programs like the one from DigitalOcean and Linode for Linux servers.

I get about 100K visitors per month, US, UK, and India. Most of my visitors are from Desktop.

Sorry if this isn't the right category for this thread, but it is a newbie question I guess.
