Faking the Funk: Mocking External Services in Python Tests

In this day and age, it’s difficult to build an application that does not rely on some type of external service. Whether the service is handling user identity, analyzing interesting data, or hurling RESTful insults, you have to accept the fact that you now have a dependency on something you do not control. One place […]

Building and Testing a Microservice in a Service-Oriented Architecture

Building a single app is hard enough. Building out multiple capabilities into that app is even harder. As part of our ongoing experience to build a full-stack monitoring tool, we recently refactored our logins out of the individual modules we’ve built and into a Microservice, built in Java. We would like to share our experience […]

One Weird Trick Front End Web Developers Don’t Want You to Know…

A few weekends ago, my Developer girlfriend and I endeavored to create a simple transit app for our Pebble smartwatches.  The cool thing was we had MVP by Saturday evening, and we were both rocking bus times on our watchfaces by Monday morning.  Could we have continued to use the transit app on our phones?

Customizing Chef Bootstrap Templates

At AppNeta, we use Chef to set up EC2 instances for the purpose of testing our TraceView instrumentation modules.  TraceView has agents for Java, .NET, Python, Ruby, and PHP, and one of the most important requirements for all of these is that they’re easy to deploy (typically less than 5 minutes). This means it should be […]

Getting Started with .NET Framework Profiling

Usually when developers talk about profiling, they mean running code they wrote in some sort of development environment to get better understanding of its performance.

Product Management: We Need Pipelines, not Roads

Living in Vancouver, surrounded by the natural beauty of British Columbia, it’s hard not to elicit a negative reaction (if not an outright protest march) when talking about a “pipeline”. But you’ll bear with me, right? AppNeta is a growing company with bright employees and savvy customers. But, like any company on the rise we’ve endured […]
