One-line Tree in Python

Using Python's built-in defaultdict we can easily define a tree data structure:

def tree(): return defaultdict(tree)

That's it!

Installing OpenBSD 7.3-current on a VisionFive2

Here are some concise instructions for getting OpenBSD 7.3-current running on a StarFive VisionFive 2 (v1.3B, though from other reports referenced below, it sounds like the v1.2 boards can also be made to work).

You will need:

An SD card of at least 1GB
An eMMC module attached to the board (though see below for a variation that should work to install directly to sd card)
Internet access
A USB TTL serial adapter that supports 3.3V (some of these support multiple voltages, but if yours only supports other voltages and not 3.3 it will either not work or damage your board!)

	# Converts any integer into a base [BASE] number. I have chosen 62
	# as it is meant to represent the integers using all the alphanumeric
	# characters, [no special characters] = {0..9}, {A..Z}, {a..z}
	#
	# I plan on using this to shorten the representation of possibly long ids,
	# a la url shortenters

	# IMPORTANT!
	# At the moment this script is forged only for Debian ( tested on 8.x release ).
	# Although my efforts were put on building this also on Arch Linux or Alpine, at the moment only Debian seems to be able to build it.
	# Also, not sure why these instructions where nowhere on the internet, therefore I leave them here for whoever need them.
