Example of how to use COPY FROM from Ruby with the 'pg' library. The last two edits are demonstrating the error case and the successful case.
#!/usr/bin/env ruby
require 'pg'
require 'stringio'
$stderr.puts "Opening database connection ..."
conn = PGconn.connect( :dbname => 'test' )
conn.exec( <<END_SQL )
DROP TABLE IF EXISTS logs;
Hi David,
I came across your profile online and wanted to reach out about Development
Opportunities here at Groupon. The company is growing, and we're always
looking for folks with solid skills that can make positive contribution to
our continued success. Any chance you'd be open to a quick conversation
about opportunities, or for any possible networking potential? If so, let me
know when you're free and we can set up a time to chat. Also, if you are
interested, it would be great if you could forward a current resume over
that I can take a look at. I look forward to hearing back from you! Please
let me know if you have any questions.

How is git commit sha1 formed

Ok, I geeked out, and this is probably more information than you need. But it completely answers the question. Sorry. ☺

Locally, I'm at this commit:

$ git show
commit d6cd1e2bd19e03a81132a23b2025920577f84e37
Author: jnthn <[email protected]>
Date:   Sun Apr 15 16:35:03 2012 +0200

When I added FIRST/NEXT/LAST, it was idiomatic but not quite so fast. This makes it faster. Another little bit of masak++'s program.

Am I doing it wrong?

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

How to migrate a DB on heroku to another plan

Recently, I had a staging database on Heroku that was running on the Ronin database (which was originally the lowest-sized DB you could get at Heroku). Since they added two new options, Crane and Kappa, we wanted to take advantage of the cost savings. Here's how you can migrate your Ronin DB to Crane (or any other plan).

The old database was named BROWN while the new one is CRIMSON. You can determine this by running:

heroku pg:info --app myapp-staging
  1. Add Crane database

     heroku addons:add heroku-postgresql:crane --app myapp-staging
    

heroku pg:wait --app myapp-staging
