Tulip Creative Computer is a small, cheap, open source PC for making music and more (available for $59, but you can also build your own)

5. Srpen 2024 v 16:18

The Tulip Creative Computer is an open source computer designed for making music or coding simple games or other applications. It’s not exactly the most powerful little computer money can buy, but it doesn’t take a lot of money to buy one: you can pick up a pre-built Tulip system for $59 or build your own […]

The hot water took too long to come out of the tap. That is what I was trying to solve. I did not intend to discover that, for a while there, water heaters like mine may have been open to anybody. That, with some API tinkering and an email address, a bad actor could possibly set its temperature or make it run constantly. That’s just how it happened.

Let’s take a step back. My wife and I moved into a new home last year. It had a Rinnai tankless water heater tucked into a utility closet in the garage. The builder and home inspector didn't say much about it, just to run a yearly cleaning cycle on it.

Because it doesn’t keep a big tank of water heated and ready to be delivered to any house tap, tankless water heaters save energy—up to 34 percent, according to the Department of Energy. But they're also, by default, slower. Opening a tap triggers the exchanger, heats up the water (with natural gas, in my case), and the device has to push it through the line to where it's needed.
