Zebras and Lasers: A crash course on barcodes with Python

Fun & People, Novice
8/18/2018 | 4:40 PM-5:10 PM | Robertson

Description

Factory automation and logistics are industries full of software and full of technologies that seem simple but aren't. This talk is a Python-filled deep dive into the surprisingly complex world of the humble barcode, a true workhorse at the interface between software and the physical world. There will be shipping labels, sidewalk mosaics and even DNA!

Abstract

Because software is nothing but electrons in a box, writing code that deals with tangible objects in the physical world is tricky. To make things easier to identify by software, we have sprinkled our world with machine-readable artifacts like RFID tags and magstripes. The most popular such tag is the barcode, clocking in at an estimated 5 billion barcode reads per day!

Despite being the ubiquitous interface between the worlds of hardware and software, barcodes rarely get much attention from engineers on either side of software/hardware divide. Only few barcode connoisseurs geek out about the nuanced benefits of the many different barcode symbologies and hundreds of industry-specific data encodings. This talk is a guided tour through the wonderful world of barcodes, curated especially for Pythonistas.

I will start with a live demo of how to read a barcode with nothing but pen, paper, and a few list comprehensions, followed by a brief barcoding theory 101. After we’ve seen the nuts and bolts, I will go over a brief survey of the packages and tools for generating and reading barcodes that are available to Python developers. We’ll finish with a few application examples, ranging from interesting to mischievous.

Warning: There might be lasers (but probably no zebras).
