With my OpenBSD developer hat on, getting new hardware in the hands of developers is really important, many of us are hacking on 5-10 year old thinkpads that need replacing.

The OpenBSD foundation is ~23% away from its fundraising goal for 2026, which helps support developer hackathons and project infrastructure, etc.

Shamelessly, if I may add a personal plea, in addition to funding the open source projects you use, if you can, please do consider directly supporting individual contributors/developers personally who work on those projects, many are volunteers and even a small monthly contribution could mean the difference.
