Proposal for a date system overhaul

The Problem

FullCalendar was initially designed without much notion of timezones. By default, it ignores timezone offsets in the dates it receives.

The original assumption was that if you received a date from Brussels, say "2013-09-01T12:00:00+02:00", which is noon, it would display as noon in every timezone.

However, FullCalendar shoehorns this value into a local date. With the same example, if you were in San Francisco, it internally stores the date as "2013-09-01T12:00:00-08:00". This is bad for two reasons:

Methods for installing Node.js on Raspberry Pi

Setting Up Node.js On Raspberry Pi

There are several ways that you can set up Node.js on a Raspberry Pi when running Raspbian/Rapberry Pi OS. Depending on your needs, the version of the RPi that you're using, and how you like to manage installs, you have a lot of options.

Node.js from source

Do not do this if you can avoid it, it's super slow. If you insist on doing it and have the time, you can start at https://nodejs.org. But really, don't do this.

If you have tons of time on your hands, don't need Node anytime soon, and insist on building from source for some reason, here's a guide you can try out that covers building Node.js on an ARMv6 Raspberry Pi.

Side note: unless you have a need for the latest and greatest features, I recommend developing using the most recent Long Term Support (LTS) version of Node available, especially for anything you plan to put into production for any length of time.

DW3000 "missing manual" notes

Overall

The DW3000 is an exciting part, available as a convenient Arduino-shield eval board with good distribution. HOWEVER, this is NOT a "maker friendly" part with SparkFun or Adafruit type tutorials and examples! It is a sophisticated radio that can be the heart of a positioning system, but you have to do quite a lot of heavy lifting to get there.

For basic use, the older-but-still-good DW1000 may be a better choice; interface libraries are available for Arduino and Raspberry Pi. Or look into packaged location-system vendors, like Estimote, Pozyx, Ubitrack and many others
