Using Python 3 + Google Cloud Vision API's OCR to extract text from photos and scanned documents

Just a quickie test in Python 3 (using Requests) to see if Google Cloud Vision can be used to effectively OCR a scanned data table and preserve its structure, in the way that products such as ABBYY FineReader can OCR an image and provide Excel-ready output.

The short answer: No. While Cloud Vision provides bounding polygon coordinates in its output, it doesn't provide it at the word or region level, which would be needed to then calculate the data delimiters.

On the other hand, the OCR quality is pretty good, if you just need to identify text anywhere in an image, without regards to its physical coordinates. I've included two examples:

Idiomatic React Testing Patterns

Testing React components seems simple at first. Then you need to test something that isn't a pure interaction and things seem to break down. These 4 patterns should help you write readable, flexible tests for the type of component you are testing.

Setup

I recommend doing all setup in the most functional way possible. If you can avoid it, don't set variables in a beforeEach. This will help ensure tests are isolated and make things a bit easier to reason about. I use a pattern that gives great defaults for each test example but allows every example to override props when needed:

Notes on the setup

Update 2023/03/02: Using Pop!_OS 22.04 LTS. Just install and enjoy, not much to say about, it just works.

Update 2020/05/19: I'm using PopOS 20.04. Works great!!

NOTE: At the moment Dell G3 series doesn't officially support Ubuntu 18.04.

Add sorting to your product taxon page in Spree

So in following @berkes 'Add sorting to your product page in Spree' guide, I tried to repeat with my taxons controller. However there was no difference in order, despite the scopes being applied.

Another commenter Adam shared my frustration: 'How would I make this work for taxons as well? Everything I try doesn't work'.

After a little bit of research, I figured it out.

TL;DR
