Calculating the Dewpoint in Ruby

I needed this today; maybe it will help someone else.

humidity should be 0-100 temp_c is a float

l = Math.log(humidity / 100.0)
m = 17.27 * temp_c 
n = 237.3 + temp_c 
b = (l + (m / n)) / 17.27
dewpoint_c = (237.3 * b) / (1 - b)

Getting to orbit is tremendously harder than going to a high altitude, but the payoff isn’t just one of magnitude, it’s one of kind. There are things you can do in orbit that you simply cannot do by jumping to the edge of space and falling back.

For those of us doing Knowledge work, the need for us to get above our worlds for extended periods of time is crucial to doing what we need to do.

The Case for Optimism

These days it’s trendy to be pessimistic. Every time we sign into Facebook our friends (or moms) are telling us about how crime is up, incomes are down, morality is on the way out, Zika virus is about to infect us all, and if that doesn’t kill us, Islamic Terrorism definitely will.
