Looking into how to retrieve SMS archives from iOS 6.

To explain the datetime mangling:
"The timestamps are not traditional timestamps of the number of seconds from 1/1/1970, but are instead based on the number of seconds from 1/1/2001 (so, there is a 31 year offset). So, we have to add the number of seconds in 31 years (978264705) to the timestamp to change it to a traditional timestamp giving the number of seconds from 1/1/1970."

Query below will pull a history of all message to and from the PHONE NUMBER specified.

# start_time is a #datetime column, Postgres stores as a timestamp, we need to use date_part to extract 'year'

Event.select("date_part('year', start_time)").uniq

# Spits out
# SELECT DISTINCT date_part('year', start_time) FROM "events"

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

A not politically correct assertion of my feelings towards a piece of software:

Note: Repetition builds cynicism, asset_sync isn't bad, but when an asset problem cannot be solved via support it gets escalated to me. Often times someone using asset_sync the problem is due to their use of the library and not from Heroku.

Backstory

The asset sync gem uploads your assets (images, css, javascript) to S3. From there you can either point browsers to the copy on S3 or use a CDN + the S3 bucket. It's a good idea, and solved a problem at one time.

It is no longer needed and you should now use https://devcenter.heroku.com/articles/using-amazon-cloudfront-cdn instead. So rather than copying your assets over to S3 after they are precompiled the CDN grabs them from your website instead. Here's some reasons why it's better.
