How to copy production database on AWS RDS(postgresql) to local development database.
  1. Change your database RDS instance security group to allow your machine to access it.
    • Add your ip to the security group to acces the instance via Postgres.
  2. Make a copy of the database using pg_dump
    • $ pg_dump -h <public dns> -U <my username> -f <name of dump file .sql> <name of my database>
    • you will be asked for postgressql password.
    • a dump file(.sql) will be created
  3. Restore that dump file to your local database.
    • but you might need to drop the database and create it first
    • $ psql -U <postgresql username> -d <database name> -f <dump file that you want to restore>
  • the database is restored

# Wraps curl with a custom-drawn progress bar. Use it just like curl:
#
# $ curl-progress -O http://example.com/file.tar.gz
# $ curl-progress http://example.com/file.tar.gz > file.tar.gz
#
# All arguments to the program are passed directly to curl. Define your
# custom progress bar in the `print_progress` function.

Performace patch for ruby-1.9.3-p327

Changes:

  • this version includes backport of Greg Price's patch for speedup startup http://bugs.ruby-lang.org/issues/7158 .

    ruby-core prefers his way to do thing, so that I abandon cached-lp and sorted-lf patches of mine.

  • this version integrates 'array as queue' patch, which improves performance when push/shift pattern is heavily used on Array.

    This patch is accepted into trunk for Ruby 2.0 and last possible bug is found by Yui Naruse. It is used in production* for a couple of months without issues even with this bug.
