The current kernel/drivers of Fedora 24 do not support the Wifi chip used on my Mac Book Pro. Proprietary Broadcom drivers are packaged and available in the rpmfusion repo.

Verify that your card is a Broadcom using: lspci -vnn -d 14e4:

Sample output:

02:00.0 Network controller [0280]: Broadcom Corporation BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03)

Install

Install the rpmfusion repo, note only "nonfree" is required, as the Broadcom Driver is proprietry: http://rpmfusion.org/

Using 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:

####### 1. A low-resolution photo of road signs

	#!/bin/bash
	yum install -y aws-cli
	cd /home/ec2-user/
	aws s3 cp 's3://aws-codedeploy-us-east-1/latest/codedeploy-agent.noarch.rpm' . --region us-east-1
	yum -y install codedeploy-agent.noarch.rpm

	<!--
	This disables app transport security and allows non-HTTPS requests.
	Note: it is not recommended to use non-HTTPS requests for sensitive data. A better
	approach is to fix the non-secure resources. However, this patch will work in a pinch.

	To apply the fix in your Ionic/Cordova app, edit the file located here:

	platforms/ios/MyApp/MyApp-Info.plist

	And add this XML right before the end of the file inside of the last </dict> entry:

	#! /usr/bin/env python
	# See http://preshing.com/20130115/view-your-filesystem-history-using-python
	import optparse
	import os
	import fnmatch
	import time

	# Parse options
	parser = optparse.OptionParser(usage='Usage: %prog [options] path [path2 ...]')
	parser.add_option('-g', action='store', type='long', dest='secs', default=10,
