Store All Files in the Cloud

It is rediculious to me that people still store files locally on their computer outside of a cloud-backed storage folder or tool.

Stop Centralizing Resources, Use Links Instead

When docs, code, resources are scattered around on various team shares, repros, etc and a new team starts up, one of the first things they think about is "hey! we should have all the docs/code in ONE place!". But there's a REASON code/files/docs are in different stores. Because that organization makes sense too.

Install Mongoose OS mos CLI Tool on Raspberry Pi RPi

I enjoy seeing how little my dev environment can actually be to accomplish cool stuff. Currently I'm using a terminal app on my iPhone to remote into a RPi0w connected to an ESP8266 dev board to code and program the ESP8266 'from my iphone'. Mongoose OS is a fantastic OS for the ESPxx family line, with it's super easy interface and tons of built-in support into the OS (configuration, common IoT platforms, event-driven javascript, libraries, etc).

// Connect card reader cable to ESP32 pins:
// DATA (yellow) = 15, PRESENT (orange) = 14, STROBE (green) = 32
// 
// I'm using Adafruit HUZZAH32 ESP32 Feather Board, but any ESP32 should work
// And the Magtek 21050071 card reader, which reads the 2nd card track only (encoded in 5 bits)
// Double check your card reader, which track(s) it reads, because track #1 is encoded differently
