Bryan Johnson has implied on several occasions that the interventions contained in his Blueprint supplements might cost as much or more if purchased individually. The supplements industry does not have a good track record here, but Bryan seems very earnest. It takes quite a bit of work to verify something like this, but it has stuck in the back of my head for several months, so I finally decided to validate this claim.

There are a few places in the world where you can reliably see these animals, and one of the most highly rated is Socorro Island, Mexico. I booked a trip with Nautilus, a liveaboard dive boat operator that is considered one of the best in the region. The trip was nine days in total, with five days of planned diving. It ended up being a really incredible adventure that I’d like to share here.

Integrating Miri into Continuous Integration (CI) workflows can significantly improve the quality of a Rust codebase by catching errors early in the development process. This can be especially important if your codebase requires the use of unsafe blocks of Rust code which may prevent the Rust compiler from catching bugs that you would normally expect it to.

In this post, I will share my experiences with configuring and using Cachepot, a tool which wraps the Rust compiler and automatically caches build artifacts using a variety of cloud storage options. This creates a cache which can be shared amongst teams, used in ephemeral CI/CD environments, and even used for distributed builds.

Designing these pipelines involves balancing a number of factors including cost, complexity, ergonomics, and rigor. In this post I will describe several of these iterations, lessons learned, and share my most recent solution in detail.
