How Static Code Analysis Taught Me About Change Management

Recently, I helped spearhead our department’s adoption of centralized static code analysis. I worked with one of our mobile engineers to research various tools and create a decision matrix for comparing options. I’ve introduced new tools to my team before, but this was my first time selecting a tool that would be rolled out and used by my entire engineering department. It was also our department’s first time trying centralized static code analysis.

Mean Time Between Loss of Sleep

“MTBLS”: I first encountered this phrase on a New Relic blog. It's a half-joking reference to a concept used by reliability engineers, Mean Time Between Failures (MTBF). I was intrigued though, and thought it would be an interesting metric to track.

We have high-resolution data about our machines' health – down to the smallest minutia – but precious little about the health of our people.

Using Serverless Config to Deploy an AWS CloudWatch Dashboard

My team’s most recent project has been really interesting - it’s a JavaScript project that includes using the Serverless Framework to deploy a variety of AWS Lambda Functions (e.g. uploading to S3 buckets and making requests to the API that we built). Part of my responsibility as QA Engineer was to set up a CloudWatch dashboard in AWS. Dashboards can be created manually in the CloudWatch service, but I wanted to create the dashboards through code deploys.

Full Stack Basics for the Non-Developer (The Complete Post)

Let's visualize and talk about the "full stack" of web development. From a developer's standpoint, we're probably talking about the layers of code involved in delivering a website to an end user. But let's back up further for a moment and just talk about a stack of things.

Reliably Monitoring MySQL Replication

Replication is a wonderful thing for your clients. Having a 'hot spare' of their database(s) for redundancy, or being able to off-load read operations from the main database to increase performance, giving your client peace-of-mind about their data and application. I won't go into setting up MySQL Replication; there are more than a few guides on that already out there (here's the official documentation).

Upgrade to PHP 5.5 on OS X 10.8 Mountain Lion

The following is a rapid installation of PHP 5.5 on OS X 10.8. This compiles 5.5 from source, including two required libraries and finding the appropriate configure command. If you are comfortable at the command line, and especially if you are comfortable compiling your own binaries, then this should take no more than 30 minutes, with the majority being the actual PHP compilation.

Let's jump right in. Here's an overview of the steps:
