    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:

                Ruby memory analysis over time
              
          
    Finding a Ruby memory leak using a time analysis

When developing a program in Ruby, you may sometimes encounter a memory leak.
For a while now, Ruby has a facility to gather information about what objects are laying around:
ObjectSpace.
There are several approaches one can take to debug a leak. This discusses a time-based approach, where
a full memory dump is generated every, say, 5 minutes, during a time that the memory leak is showing up.
Afterwards, one can look at all the objects, and find out which ones are staying around, causing the

    Better Jasmine Tests With this

On the Refinery29 Mobile Web Team, codenamed "Bicycle", all of our unit tests are written using Jasmine, an awesome BDD library written by Pivotal Labs. We recently switched how we set up data for tests from declaring and assigning to closures, to assigning properties to each test case's this object, and we've seen some awesome benefits from doing such.
The old way

Up until recently, a typical unit test for us looked something like this:
