I am the owner of lvh.me. And I'm glad to hear it's helpful. In truth, it's just a fancy DNS trick. lhv.me  and all of it's sub-domains just point back to your computer (127.0.0.1).  That means running ssl is as simple (or difficult) as running ssl on your computer.

I'm not sure how comfortable you are with the command line, but here's my how I setup my development environment. (rvm, passenger, nginx w/ SSL, etc).


# Install rvm (no sudo!)
# ------------------------------------------------------
bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-head )
source ~/.rvm/scripts/rvm
rvm install ree-1.8.7-2010.02

Sphinx Statistics

I’ve been working on a Thinking Sphinx add-on for Heroku. It’s not launched yet, and I’m ironing out the possible plans I’ll offer. One key piece of information I’d love to have is a rough rule of how much RAM a searchd process uses in relation to how big the index files are.

If you’re using Sphinx on an app, and are willing to share this information, it’d be wonderful if you could get in touch with me, via email (pat at freelancing-gods dot com), or via twitter.

I’m after real (ie: production) data – development environment stats aren’t quite so useful :)

Here’s how I check the stats on my own sites:

# Converts a mysqldump file into a Sqlite 3 compatible file. It also extracts the MySQL `KEY xxxxx` from the
# CREATE block and create them in separate commands _after_ all the INSERTs.

# Awk is choosen because it's fast and portable. You can use gawk, original awk or even the lightning fast mawk.
# The mysqldump file is traversed only once.

# Usage: $ ./mysql2sqlite mysqldump-opts db-name | sqlite3 database.sqlite
# Example: $ ./mysql2sqlite --no-data -u root -pMySecretPassWord myDbase | sqlite3 database.sqlite

# MySQL.  Versions 4.1 and 5.0 are recommended.

# Install the MySQL driver:

# And be sure to use new-style password hashing:

Transactions

As your business logic gets complex you may need to implement transactions. The classic example is a bank funds transfer from account A to account B. If the withdrawal from account A fails then the deposit to account B should either never take place or be rolled back.

Basics

All the complexity is handled by ActiveRecord::Transactions. Any model class or instance has a method named .transaction. When called and passed a block, that block will be executed inside a database transaction. If there's an exception raised, the transaction will automatically be rolled back.

Example
