Deploying a subfolder to GitHub Pages

Sometimes you want to have a subdirectory on the master branch be the root directory of a repository’s gh-pages branch. This is useful for things like sites developed with Yeoman, or if you have a Jekyll site contained in the master branch alongside the rest of your code.

For the sake of this example, let’s pretend the subfolder containing your site is named dist.

Step 1

Remove the dist directory from the project’s .gitignore file (it’s ignored by default by Yeoman).

Migrating from Postgres 9.0/Postgis 1.5 to Postgres 9.2/Postgis 2.0 on Heroku

This may not be relevant to many, but it's a process that I just had to go through and it was a bit tricky to figure a smooth way to make it work.

The gist of it is that you must do the following:

• Export your production database from heroku to your local machine
• Create a new, blank database with Postgres 9.2 and PostGIS 2.0
• Import your heroku database into the new local database running 9.2/2.0
• Dump the new database and upload it to S3

# You have your csv data and it looks like so... It's in a file named "my_data.csv" and we want to import it into a table named "my_things".

"1", "Something", "0.50", "2013-05-05 10:00:00"
"2", "Another thing", "1.50", "2013-06-05 10:30:00"

# Now you want to import it, go to the command line and type:

$ PGPASSWORD=PWHERE psql -h HOSTHERE -U USERHERE DBNAMEHERE -c "\copy my_things FROM 'my_data.csv' WITH CSV;"

# Voila! It's impoted. Now if you want to wipe it out and import a fresh one, you would do this:
