This will hopefully be a short post, as I haven’t been up to anything particularly interesting recently. We deployed the service we’d been working on, and everything appears to be going swimmingly. The log aggregation that we setup is doing its job (allowing us high visibility into the operations of the service) and we’re slowly introducing new users, making sure they have a great experience.

As a result of the recent deployment, we’re in a bit of a lull, so I took this opportunity to work on our development infrastructure a little bit.

Well, I didn’t start out with the intent to work on our infrastructure. I just wanted to update this component we have that seeds demonstration data into our new service. When I got into the code though, I found that we had a bunch of shared code that was duplicated. Mostly code for dealing with the models inherent in the service and with authentication to the service. The approach that had been taken was to simply copy the code around, which is not generally a good idea in the long run. The demonstration data component didn’t have the copied code (yay!) but it was referencing the libraries of another solution directly from their output directory, which meant you had to remember to compile that other solution before the demo data, which is a bit crap.

All in all, it was in need of a clean up.

Fairly straight forward, split the common code into a different project and repository, create a new TeamCity build configuration to make it output a Nuget Package and reference it like that.

Its never straightforward.

Free As In Beer

We currently use TeamCity as our Nuget server, with the outputs of various build configurations being added to the Nuget server when they are compiled. The downside of this is that you can’t actually publish packages to the TeamCity Nuget server from outside of TeamCity. Another downside of the TeamCity Nuget server is that the packages are tied to the builds that made them. We have had issues in the past with packages disappearing from the the Nuget server because the build that created the package was cleaned up. It makes sense when you think about it, and we should definitely have pinned those builds to keep them forever, but its still another thing that we need to remember to do, which is vulnerable to human failure.

The free version of TeamCity is pretty great. 3 build agents and 20 build configurations are usually enough for small teams, and the product itself is pretty amazing. When you hit that build configuration limit though, you need to pay a few hundred dollars. That’s fine, its a solid product and I have no problems in giving JetBrains (the company that make TeamCity) money for their efforts.

Getting money out of some organizations though, that can be a giant pain. Which it was.

Time for an alternate approach. Time to setup our own Nuget server.

Nuget makes this pretty easy. Just create a new, blank ASP.NET web application and add a reference to the Nuget Server package. Easy.

When you’re building a piece of infrastructure though, you want to go to a bit of trouble to make it nicely encapsulated. So I leveraged some work we’d done as part of the new service and created a deployable package for our Nuget server, an Octopus project to deploy it and an environment for it to be deployed to via AWS CloudFormation. While I was there I added the logging components to make sure we have records of what is being uploaded and downloaded from the server.

Yak Shaved, Moving On

Now that I had a Nuget server separate from TeamCity, I could split out the common components into their own repository and construct a build/publish script to publish to the Nuget server from my local machine (with the intent to turn it into a TeamCity build configuration later, when we finally pay money).

I’ve done this before so I just grabbed my .NET Library Repository template and added the new solution with the project and its tests. The build script in the template automatically picks up the solution file, restores its packages, automatically generates a version, compiles it with MSBuild and then publishes a package for the single non-test project. Its pretty simple, I just use it to get reusable libraries up and running ASAP.

I did have a few difficulties with untangling the common code from the rest, which is probably why it was copied in the first place. The easiest way to go about this sort of thing is to create a brand new project and namespace and just migrate the minimum amount of code that is needed by the other components. If you try and take everything at once, you’re going to have a bad time.

Now with the magic of Nuget I just need to add a reference to the new package in the various places that need it and delete the duplicated code, running the tests (where they exist) to ensure that I haven’t broken anything.


Its important for the health of your code base to execute this sort of clean up when you see an issue like duplicated code.  Some people would say that some duplicated code isn't too bad, and I would generally agree. However, you need to be able to tell a very good story for why the code is duplicated, and not just accept that it is. Its usually not too hard to extract a library and create a Nuget package, assuming you have the infrastructure setup to support it. Which you should. If you don’t, you should set it up.

If you’ve never heard the team “Shaving a Yak” before, you can blame Scott Hanselman for that one. He did a blog post on the concept and I have never seen anything that better describes an average day in the life of a software developer. I use the term a lot whenever I’m doing something I never expected to be doing due to some crazy causality chain, which happens more than I would like.


Fellow developers, this is a call to arms! Too often I see developers who immediately cave to external pressure to “just get it done”. “Just” is a dangerous word when it comes to software development anyway. Don’t do it! Stand up for your code, don’t compromise on quality just because someone is breathing down your neck. Take a few moments to think about the impact of what you are being asked to do, both to you (as the current developer) and to others (mostly future developers).

No-one wants to work inside crap code, but people seem to be more than happy enough to create it under pressure. Sure you might think that you’ll just fix it up next time, but I’ve found that that hardly ever happens.

Do you think that overbearing project manager is ever going to have to suffer through maintaining or refactoring code that “there wasn’t enough time to test” or that is unclear as a result of “we need to just get this done now, we’ll refactor it later”? Nope. The project managers job is to get the project to some previously decided definition of done and they may be more than willing to sacrifice fuzzy things like “code quality”, “readability” and sometimes even “test coverage” or “scalability” in exchange for things that they are directly measured against like “deadlines” and “fixed scope”.

The representatives of the business will fight hard for what they believe is important. As a developer you should fight just as hard for the code. If the business representative is fighting for the “just get it done” point of view, you should fight just as hard for quality, readability, maintainability, cleanliness, and all of those other things that good code has. Stand up for what you believe in and make sure that you’re creating code that is pleasant to work with, otherwise you're going to start hating your job, and nobody wants that to happen.

I’m not prescribing that you just do what you want. That’s silly. You can’t just spend 3 months coming up with the most perfect architecture for solving problem X, or you might be surprised when you come up for air just in time to get made redundant because the organisation doesn’t have any money left.

What I am prescribing is that you fight just as hard for the code as other people fight for other things (like deadlines, estimates, contract sign-off, scope negotiation, etc).

As far as I can see there are two approaches to championing your code.


Never attribute to malice that which is adequately explained by stupidity.

Robert J Hanlon

You (as a professional developer) know why quality is important, but other people in the organization might not. They might not realise the impact of what they are (either implicitly or explicitly) asking you to do.

You need to communicate the importance of taking the time to create quality to the people who can actually make decisions. Of course, you need to be able to talk to those people in the language that they understand, so you need to be able to speak about things like “business impact”, “cost of ownership” and “employee productivity”. Its generally not a good idea to go to someone in Senior Management (even if they are technical) and start ranting about how the names of all of your classes and methods look like a foreign language because they are so terrible.

If your immediate superior doesn’t care, then go over their head until you reach someone who does. If you don’t find someone who cares, look for a better job.

Obviously be careful when doing this, as you could land yourself in some very awkward situations. At the very least, always be aware that you should show as much loyalty to your organisation as they would show you.

Do It Anyway

The conventional army loses if it does not win. The guerrilla wins if he does not lose.

Henry A Kissinger

If you feel like you are trying to communicate with a brick wall when it comes to talking about quality, you might need to engage in some “guerrilla craftsmanship”. Don’t explain exactly what you are doing in the code, and keep following good development practices. If you’re asked for estimates, include time for quality. Get buy-in from the rest of your fellow developers, create a shared coding standard. Implement code reviews. Ensure that code is appropriately covered by tests. To anyone outside the team, this is just what the team is doing. There’s no negotiation, you aren’t asking to develop quality solutions, you’re just doing it.

When that external pressure comes around again, and someone tries to get you to “just get it done”, resist. Don’t offer any additional information, this is just how long its going to take. If you are consistent with your approach to quality, you will start delivering regularly, and that external pressure will dissipate.

Be mindful, this is a dangerous route, especially if you are facing a micro-manager or someone who does not trust developers. As bad as it sounds, you may need to find someone to “distract” or “manage” that person, kind of like dangling some keys in front of a baby, while you do what you need to do.


Fight for your code.

No one else will.
