At EasyBib, we’re heavy users of composer and AWS OpsWorks. Since we recently moved a lot of our applications to a continuous deployment model, the benefits of speeding up the deployment process (~4-5 minutes) became more obvious. Composer install Whenever we run composer install, there are a lot of rount-trips between the server, our satis and Github (or Amazon S3). One of my first ideas was to to get around a continous reinstall by symlinking the vendor directory between releases....

While re-writing a couple SQL statements into CouchDB we got stuck when we wanted to do a SELECT MAX(...), id ... GROUP BY id in CouchDB. MySQL Imagine the following SQL table with data: In order to get the latest deploy for each project, I’d issue: Simple. But what do you do in CouchDB? CouchDB My documents look like this: So, after more than a couple hours trying to wrap our heads around map-reduce in CouchDB, it’s working....

Last week I blogged some Vagrant tips and pretty much jinxed the run I had in the past months. Here’s how: I decided to upgrade to Vagrant 1.1, which broke bento: the current bento master is incompatible with Vagrant 1.1. But selecting the right rbenv env and installing the latest available Vagrant gem (inside the rbenv environment) fixed it. My base box build, but for some reason, the guest addition setup broke and while it worked on Mac OSX, it broke the image completely on Ubuntu....

At the last meetup of the Berlin PHP Usergroup, Christoph gave a talk about Vagrant. Good enough of a reason to write down or re-cap some things I’ve learned with or about Vagrant over the last two years. Base boxes There are lots of base boxes available, but don’t be tempted to rely on them (e.g. via config.vm.box_url). Vagrantbox.es doesn’t actually mirror images and that is a huge pain. Available base boxes tend to be outdated....

I’ve blogged about converting a Subversion repository to git a couple times. While it was a tedious process at first, I’ve made my peace with it and now cannot count the code repositories I have migrated successfully anymore. The migration usually works, except for when I deal with our old provider unfuddle. For some reason, sometimes it didn’t work right away and I had to re-run git svn clone a couple of times to get it right....
