Started with me trying to resolve this error:

import requests
requests.get('https://www.salesforce.com')

SSLError('bad handshake', Error([('SSL routines', 'SSL23_GET_SERVER_HELLO', 'sslv3 alert handshake failure')]

And I believe this is the cause as per https://github.com/superfell/Beatbox:

rob-murray

columns_that_make_record_distinct = [:some_id, :another_name]
distinct_ids = Model.select("MIN(id) as id").group(columns_that_make_record_distinct).map(&:id)

duplicate_records = Model.where.not(id: distinct_ids)

Moving to ES6 from CoffeeScript

I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.

In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.

While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.

Punctuation

Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

How to setup Heroku Hostname SSL with GoDaddy SSL Certificate and Zerigo DNS
Heroku recently added an exciting new 'Hostname SSL' option.  This option offers the broad compatibility of IP-based SSL, but at 1/5 the price ($20 / month at the time of this writing).  
 
The following tutorial explains how to use Heroku's new 'Hostname SSL' option on your Heroku project.  Before we begin, let's list what we're using here:

    * Heroku Hostname SSL
    * GoDaddy Standard SSL Certificate
    * Zerigo DNS
