(NB: adapted from this Ask Ubuntu thread -- tested to work on Ubuntu 16.04 LTS through Ubuntu 22.04 LTS (Jammy).

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.

TL;DR

Install open-vm-tools and run:

sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).
