In the previous post I wrote about our pre-chef approach for instance bootstrapping.

Provision machines with AWS – custom bootsrapper
In the previous post I wrote a little about our transition to AWS.
Now I will tell a little more about our instance bootstrap process.

History of infrastructure at FastCompany
Recently I started doing quite a bit of operations stuff at FastCompany, so I decided to write couple articles to illustrate our transition to AWS and later to Chef. There were few bumps on the road, some of you may be able to avoid them by reading these posts .. …
Nullmailer and Fakemail – two little tools for every developer
From time to time I need to work with outgoing mails: change templates, make sure they display correct data etc. You could go with some full blown MTA like postfix and it’s actually pretty easy to install and configure for outgoing mail sending. I personally tend to not install MTA on my dev box, …

Moving single MySQL database to tmpfs
Recently I had a problem running Drupal Simpletest on my new i7 dev box. It took couple minutes to execute a set of relatively simple tests and as a developer you probably know how annoying that could be.

How I solved MySQL I/O problems during cache purges in Drupal
Recently I’ve built pretty powerful workstation with I7 CPU and lots of RAM, but noticed very poor performance during devel/cache/clear operations in Drupal. In fact this operation was 5 times slower than on my 3yrs old dev box.
