INSERT INTO visits (ip, hits)
VALUES ('127.0.0.1', 1)
ON CONFLICT(ip) DO UPDATE SET hits = hits + 1;

Stubbing a class method with Sinon.js
...ensor.prototype.
sinon.stub(Sensor, "sample_pressure", function() {return 0})
is essentially the same as this:
Sensor["sample_pressure"] = function() {return 0};
but it is smart enough to see that Sensor["sample_pressure"] doesn't exist.
So what you would want to do is something like these:

Does uninstalling a package with “pip” also remove the dependent packages?

Java Round up Any Number
... correct function to call. I'm guessing a is an int, which would make a / 100 perform integer arithmetic. Try Math.ceil(a / 100.0) instead.

System.out.println(Math.ceil(a / 100));
System.out.println(a / 100.0);
