Dynamic includes in Salt

Writing Salt state files can be somewhat deceptive. They have a concept of includes, which allows you to split up state files and define dependencies, which can give you reduced duplication, a cleaner top.sls and a way to run state files individually without dropping all your requirements. However, unlike Python and other programming languages, the includes don't need (it's not even considered best practice) to be defined at the top of the file. Realizing this opens some opportunities.

Wait for a port to be listening in Salt

Sometimes, you want to wait for a service to be running before running other states. Usually this can be done with a service.running state, which is then required by other states. For example, a mysql_database.present state can require the mysql service state, and it won't be ran before the mysql service has been started.

Dangers of targetting grains in Salt Or how to properly do role management with Salt

Targetting grains is probably the most widespread bad practice in Salt. It helps reduce verbosity and duplication in your top files, but also opens up some serious security holes in the event that a minion should be compromised.

Hints towards learning SaltStack

SaltStack is an awesome provisioning tool I've been implementing in the past few months. I'd like to share a few pointers to other people working with it for the first time.

Git(hub) - Push via SSH, pull via HTTP(S)

I work with public Github repositories a lot, and get super annoyed because I want to push with my SSH key (because I'd rather put in my key's password than my Github username/password), but I want to pull with HTTPS (because then I don't have to put in a username or password). Normally, the way you do this is:

SASS tests with a simple Makefile

Working with increasingly complex SASS mixins and functions recently, I wanted to set up some sort of test suite to check the CSS output of various files. Rather than bother with some silly NPM package/Ruby gem, I figured I might as well just use some basic shell commands that can be placed in a Makefile (which I already had anyway).

Laravel and SemVer

There's been some discussion around Laravel and SemVer (semantic versioning) recently, which I appreciate. SemVer is in my eyes a very important guideline for frameworks and widely adopted libraries.

Assertions on mails in Laravel 4

Testing mails in Laravel 4 is a bit of a weak spot. You can say Mail::shouldReceive('send')->once()... but specifying everything the method should receive in terms of arguments as well as asserting that the closure sets the recipient and subject correctly is tedious at best. This SO answer shows an example of how to unit test a mail being sent.

Over the weekend I had a fun little project - writing a tiny static HTML blog generator.

Crunchbang and lx* packages

I've been running Crunchbang as my main linux distribution for a while now, and have had a really good time with it. Recently I stumbled upon a problem, and thought I'd just put my solution out there.

Using the Form Builder as little as possible

I love the Laravel 4 FormBuilder (accessible through the Form:: facade) - automatic re-populating of input from the session and from a model is awesome. In the upcoming versions you will even be able to use accessors to populate form fields from the model even if they're not actually fields in the database.

When to use repositories?

Repositories have their place in applications that deal with fetching stuff - either if it's from a database or an external source. In the Laravel world the repository pattern has been praised a bit too much for its advantages in terms of testability and architecture. I've written about how you can achieve the same level of testability without repositories, but sometimes repositories really are recommended.

Testable, simple L4 code without repository patterns

There's a lot of people advocating the repository pattern for testability in your Laravel 4 projects. Fact is, it doesn't make your code that much more testable, and you can easily achieve the same level of testability by using your models as you would a repository.

Assertions on method calls using Mockery

I had a problem recently where I wanted to use PHPUnit to test what was being passed to a function. We're talking about a several hundred line string with a current timestamp, so simply using $mock->shouldReceive('method')->with('parameter string') wouldn't work.

Optimizing for production with Laravel 4

Documentation on optimization and performance is somewhat lacking for Laravel 4 at the moment. In this post I'll give some quick pointers as to how Laravel 4 works and how you can improve its performance.

Volume in Debian distros (Crunchbang, Ubuntu...)

I've had this problem with my old Lenovo ThinkPad with every Linux installation. When I installed CrunchBang (a great disto, by the way) I had it again and had forgotten how to fix it. Amazingly, by googling around I found my own old blog with a post on how to fix it from all the way back to Ubuntu 9.10. I decided to re-write it a bit and host it here.
