A Day in the Life at Moontoast

| Comments

I had jokingly asked on Twitter for topics for blog posts for this week, planning on blogging something last night too, but I ran out of time before I headed out to play softball. Let’s here it for dedication to task! Matthew Turland had suggested I talk about the day in the life of your grumpy programmer at Moontast. Not missing an opportunity to be a smartass, I asked Matthew if he really wanted to know before my boss piped up that it involved lots of “blood, sweat and swear”. Thanks to Terry Chay for that awesome quote.

Given that Moontoast is currently hiring some PHP developers (ahem, Server Side Engineers) to either work in our offices in Nashville, Boston or remotely in North America, perhaps this is a very timely post. Don’t worry, I’m not going to reveal any trade secrets or ask you to peer review the code I’ve written. I’ll save that punishment for those folks we actually hire. Instead, I want to focus a bit on work flow and our infrastructure.

With most of the team in Nashville, that means they are on Central time. Since I’m in the Eastern timezone, that gives me the first hour of the day to focus on planning my day. Yes, I’m sure you shocked that I actually make notes and try to plan ahead of time the things I want to work on that day. Lately I’ve been working on a SOAP-powered API. Don’t worry, I can hear you snickering while you read that. It’s meant to be compatible with Magento’s for strategic business purposes.

As part of my tasks I also identify who on the team I need to speak to if they are a potential block. Being a remote worker means that communication is incredibly important, and quick turnaround time is essential to avoid me sitting in my basement wasting my time. With my list of potential targets for my anger secured, I connect to the dev environment I’ll be using and start coding away.

At Moontoast all our stuff is up in the cloud. EC2, S3, ELB, MySQL on RDS and MongoHQ. My two dev environments are up there too, so I spend pretty much all day using Vim. I did try using Expandrive to mount remote directories and then edit things via MacVim (as I do prefer it) but I found that it was impossible to use my most essential Vim plugin to find the files I needed to work on. So I instead duplicated my Vim setup on my two dev instances and away I go.

I end up learning a lot of devops stuff while I build the applications. Specifically learning how to make all the different pieces talk nicely to each other, and then creating configurations that allow me to pull in data for testing purposes from pretty much any environment we are using. If you have not learned the power of tunnelling database connections over SSH you have missed out on some powerful tools.

We also use Git for our version control. It took me a few months to get comfortable using it (still run into the odd problem but they are fixable with a little research or swearing until someone helps) and I think I’m okay with it now. I don’t do anything fancy like cherry-picking commits to build artisanal pushes that are a thing of beauty. We keep things simple and stick to this workflow, with the added change of using a stage branch.

Oh, and if that wasn’t confusing enough, the two different products we have use two different branching structures. Fixing that AND getting rid of the stage branch are high on the list of system integration tasks I want to do. That and fixing our current deployment system.

Right now we use something that is actually quite awesome called Whiskey Disk, a tool that (almost) delivers on the promise of “embarrassingly fast deployments”. I do like it but I feel that we’re moving to a system that needs to be more tailored to my goals of continuous delivery of code. We have a cron job setup that monitors for changes to several branches, and then triggers a deployment if it notices a change. It is cool, but I would prefer some more control. Sometimes I feel like waiting 10 minutes for changes to show up is unacceptable. Some of my objections are also of a philosophical nature. They are doing deploys using in-place updates of code instead of copying code into a directory, swapping symlinks, and then flushing the opcode cache. A minor detail to some, but if you start relying on pieces like this you really need to do it right.

Magical deployments is cool, but I feel like we are moving towards a scenario where we need more control of what gets deployed where. One thing I do like is the concept of separate repositories for the application and the config files for the application, allowing for pushing just config changes out instead of the whole app. I find it handy, but again, I have a desire for more control on what goes where. My perfect tool is a cross between WePloy and the recently-released Deployinator. Etsy’s tool looks the closest to what I like, but we shall see. Something in PHP is more comfortable as Deployinator is a Sinatra app and my Ruby is WAY out of date.

So, when I work I am either doing coding in a ‘hotfix’ branch to fix a bug or a ‘feature’ branch when creating new things. For example, my SOAP API work is in the ‘feature-api’ branch. I commit my stuff often, usually after I’ve tested stuff out (more on that later) and I also push to my branch quite often as well. Mostly because it provides proof to the team that I am working on stuff as all pushes are tracked and a bot emails the dev team AND posts a message in our IRC channel that code has been pushed.

You notice I talked about tests. The amount of tests we have on what is a fairly complex set of products is appallingly low. I do feel shame, and while building the API I’ve been using PHPSpec as the testing tool. While I’ve been a big believer in unit testing in the past, it seems to me that a Behaviour Driven Development approach is likely to achieve better results overall. BDD lets me talk to our product managers and very easily convert their criteria for a feature successfully working into tests. I’m in the early days of PHPSpec and BDD so I’m sure I’ll have more thoughts on this in the future. Either way, the time to commit to tests is now. I’ve been through the death march of watching a team trying to write tests after the fact for a large application. Not pretty.

To be perfectly honest, having good tests is like having six-pack abs – everybody wants them but nobody wants to do the work to get them. Tests are the first step down the continuous delivery path, because if you write tests then you can have the running of those tests automated via continuous integration. I’ve spoken about CI before, so I won’t waste any more time on it.

So, I have code I’m writing in Git branches and are writing tests for all new features I’m doing. Next step is to figure out how to complement the work I’m doing with PHPSpec with the use of Cucumber to let me test the rest of the site. There are some challenges due to the use of Facebook Connect for authentication, and heavy use of Ajax in the applications. They are great from a user perspective, but a pain in the fucking ass to try and write automated tests for. While Cucumber is aimed more at Ruby folks, Cucumber is also able to test non-Ruby apps. Again, it will be an uphill struggle but one that I think will pay off in allowing increased delivery speed.

Now, we do have meetings every single day. We are using some scrum-like system, but it basically boils down to talking to each other for 5 to 10 minutes every day to go over what we’re working on to see if anyone needs help or to tell them if you’re done early and can tackle another problem. Yes, sometimes I get stuff done ahead of schedule and then declare my desire to spend time on a another task, usually something related to infrastructure work. Our meetings are usually just before my lunch time, and often they result in my slightly modifying what I’m working on in the day. I have some lunch and then get back to work.

So there you have it: a day in my life at Moontoast. There are a lot of cool challenges to make the whole infrastructure better, but they are the type of challenges that I think will not kill you but really make you stronger. Wish me luck!
