#TL;DR For printing integers, using your own method (see print.c) to print out each decimal digits into a fixed buffer uses about 90% less time than using a format print function such as snprintf.

#setup

# print.c is the source code used for testing.
# to compile the source for print method M
# If M is between 1 and 12, it uses a particular format string to print
# Otherwise, the customized unsigned int print function is used to print one integer (result is equivalent to method 6)

Iowa Liquor Sales dataset via Socrata/data.iowa.gov

(preliminary exploration)

The state of Iowa has released an 800MB+ dataset of more than 3 million rows showing weekly liquor sales, broken down by liquor category, vendor, and product name, e.g. STRAIGHT BOURBON WHISKIES, Jim Beam Brands, Maker's Mark

This dataset contains the spirits purchase information of Iowa Class “E” liquor licensees by product and date of purchase from January 1, 2014 to current. The dataset can be used to analyze total spirits sales in Iowa of individual products at the store level.

You can view the dataset via Socrata

Grundsituation:
Es gibt einen Community-Mesh-Prefix (z.B. /18)
Der Prefix ist in Blöcke von z.B. 4 Adressen unterteilt (ein /18 ergibt 4096 Blöcke a 4 Adressen)
Knoten multicasten periodisch Listen ihrer reservierten Blöcke, um Konflikte zu erkennen
Jeder Knoten hat irgendeinen Identifier (untere 8 Byte der IPv6-Adresse?)
Jeder Knoten unterhält eine Liste der Blöcke mit zuständigen Knoten
Situation: Ein Knoten braucht neue Adressen (z.B. auch nach Boot)
1. Der Knoten wählt zufällig einen der Blöcke aus (gegebenfalls unter Ausschluss schon bekannter von anderen Knoten verwendeter Blöcke)
1. Der Knoten fragt mehrmals per Multicast im Mesh, ob der Block schon verwendet wird

	This script uses Github's API V3 with Basic Authentication to export issues from
	a repository. The script saves a json file with all of the information from the
	API for issues, comments, and events (on the issues), downloads all of the
	images attached to issues, and generates a markdown file that can be rendered
	into a basic HTML page crudely mimicking Github's issue page. If the gfm module
	is available, the script will go ahead and render it itself.

	In the end, you'll be left with a folder containing a raw .json file (which you
	can use to extract information for your needs, or to import it somewhere else),
