ErikDeBruijn / seed-split.py
Created September 21, 2017 21:11
seed spitting
# ==== The dilemma: security versus access ====
# Nervous writing down your valuable seed phrase on a piece of paper?
# But worried that if you don't, you might lose access?
#
# ==== The easy (risky) way out ====
# Very commonly, people split their seed phrase in x equal parts, however,
# THIS IS VERY INSECURE. An attacker that obtains even one split has
# significantly easier job of compromising your key and steal to your
# crypto assets/currencies.

ErikDeBruijn / tesla-finish-charge-at.js
Last active January 29, 2016 22:35
A little script to finish charging my car just before I want to leave
#!/usr/bin/node
/*
This script does four things for Tesla Model S owners:
- it helps increase battery longevity
- saves money if your utility charges night-time power differently
- gives you a more pleasant start of your drive
- preheats for you in the morning, no need to open up the App.
How?
You tell it when it should complete its charge and what percentage.
