Unfortunately gas stations don't actually make much money from selling you fuel. Most of the money is made from the attached convenience stores.

Almost two decades ago, I worked at a network service provider who had as a customer a company that provided the technology for serving those gas pump ads.

At each gas station they had a VSAT, a router and of course the digital signage boxes on each pump.

They fed the ads to thousands of pumps via a single T1 to HughesNet in Atlanta. They'd multicast the ads, and have a local cache at each pump that would receive the stream, cache it and serve it.

It was one of the most elegant setups I've ever seen, and should serve as a case study in multicast for efficient bandwidth utilization across an expensive data transmission medium.

If you want to see doctrings in action, take a look at Salt (https://saltproject.io/). They're used to build all the module documentation (https://docs.saltproject.io/en/latest/py-modindex.html) using sphinx and they won't accept new modules without them.

I second that. Chamberlain's/Liftmaster's MyQ app grows more ad-infested by the day and the RatGDO gives you local control (no cloud required)

Yup, specifically a base64 image encoded inside a Markdown document.

This can probably be accomplished with Tasker. Tasker can definitely disable the screen timeout, and my guess can lock the phone as well.
