It was gusting at 33kts.
33kt/hr * 1.15mi/kt * 1.609km/mi ~= 61km/hr.
The weather app was right. Just different units.

There was an interesting problem about qanats and excavation cost minimization in the 2015 ICPC World Finals problem set.

You can probably get away with undergraduate degree graduation year as a rough proxy for age.
age(grad_year) ~= (2016 - grad_year) + 22

You generally don't know if you've reached a suitable maxima, which is why it is good to run a nondeterministic optimizer a few times (if computation power allows) and see if there are any reliable parameters form there.
There are also somewhat better-than-random strategies such as Bayesian optimization and particle swarm optimization that can help you to search more efficiently.

Is there any way to set tcpKeepAlive=true, ssl=true, and specify a sslrootcert (for Redshift use)?

CART forms the basis of the decision trees used by scikit-learn's implementation of random forests [1]. CART may be old, but definitely not outdated.
