Fighting Climate Change

At Our Electrification Journey, I share many details of electrifying our home (heat pump HVAC, induction stove, heat pump water heater, etc) to help make it easier for others, too.

I’m a certified Rewiring America Electrification Coach and a member of a local coaches group so I can better support those in my community who are interested in electrifying.

Making our communities better

I volunteer with a non-profit supporting our local library and donate to many other non-profits (including KQED, Meals on Wheels, and our local food bank).

I helped the co-founder of Stack Overflow and Discourse improve access to the American Dream by designing and launching a $50MM Guaranteed Minimum Income study in partnership with GiveDirectly by giving more than a thousand households $1,500 per month for 16 months to spend on food, business, rent, or whatever they need most.

    Major Components Load Center This is where everything comes together: PV, Battery, Home, and Grid (via the Tesla Gateway).

  • Home Electricity Fundamentals

    Electrical Energy Fundamentals While energy generally flows in one direction through the network of wires in your home — from the grid, towards your outlets — they don’t have to. You could plug a generator into any outlet in your home (but don’t do this, it’s dangerous) and energy flows “backwards” from that outlet to…


  • Reader-augmented Writing

    Words gave us the ability to effectively share ideas and knowledge, and writing allowed those words to spread further and be carried across time. The printing press accelerated that spread, and electronic mediums allowed even more people to share ideas more quickly. Yet articles and books — even e-books — are still largely static and…


  • Containerized Passenger Transportation

    Getting someone from point-A to point-B will often — even in the distant future — involve a variety of methods of transport. For example, getting someone from their home in San Francisco to an office in Los Angeles might primarily (the majority of the distance) be served by something like high-speed rail or Hyperloop. However,…


  • HTTP Status Codes 401 Unauthorized and 403 Forbidden for Authentication and Authorization (and OAuth)

    When a client requests a resource from an HTTP server and it’s not allowed to access that resource, the client needs to know enough about why in order to present the right message or options to the user. Basically, we need to know whether the user can do something about it or not. HTTP status…
