Writing React.js is fun... But being able to draw React components, design responsive layouts and create entire app flows visually can be even more fun! (Especially for those non-coder members of your team who think ECMAScript 6 is a skin disease. They should see the light of React too.)

In this lightning talk, we'll give you a world premiere sneak peek at React Studio (www.reactstudio.com), a GUI tool built specifically for React. We'll explain how React's functional design makes it a great fit for visual tools. Also we will show how React Studio's plugin approach makes it a really powerful meta-programming system. Want to switch your app from Redux to Alt.js or vice versa? Just swap the state plugin and export again! That's just one of the joys of using a visual system for your Reactified visual design.

Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

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:
