  • To explain how HAproxy and competing tools solve this:

    Two servers are prepared to be the single reverse proxy, but one is active. They constantly communicate with a “heartbeat”. When the active one fails to send a heartbeat, the secondary executes the steps to become the active primary. When the primary’s heart starts beating again, it becomes active again.

    So there can be a few seconds of downtime, but the failover is automatic.






  • Part of the app resides on the GitHub infrastructure, where GitHub stores, processes and displays results. So their costs are not zero.

    But GitHub could take a “tax the rich” approach to pricing by charging enterprise customers more for self-hostingand leave it free for others.

    A lot of open source is funded like that— most funding for a project comes from a very few companies and everything else uses it free or for very low donations or costs.













  • Imagine a beach of infinite length with one lemonade stand on it.

    Where do you open a second lemonade stand to maximize sales if people will buy from the closet stand?

    The answer: next to the first stand. Everyone to the left of your stand will find you are the best option and everyone to the right will choose the other.

    This model explains why two political parties along a spectrum can end up not too different from each other in an attempt to capture the most votes.
