Ten User Testing Ideas that Really Work

Chris Greacen

Whether you’re building a swingset in the backyard or coding a blockchain ledger for microtransactions, you’ll soon know the value of user testing. Sometimes just trying to find the users to talk to teaches you something that you can put into your product. Listening to the voice of your user is such a powerful thing--we think these ten ideas will help you start off on the right foot.

Mount Amazon EFS Drives Inside Docker for Simple Network Storage

Brien Wankel
Principal Engineer

At Lab Zero we ran into a use case a while back where we had some files that needed to be created and shared across Docker containers in the same EC2 Container Service (ECS) cluster. We typically use S3 for solving most types of shared storage situations, but in this case, we needed the storage to be mounted locally on each container instance. Thankfully Amazon Elastic File System (EFS) fit the bill. It provides elastic storage that can be mounted as an NFS drive with just a few simple steps.

Including a Device Tree Overlay in an Elixir Nerves Project

Brien Wankel
Principal Engineer

I’ve been working on a Raspberry Pi 3 and Elixir Nerves project that utilizes an additional piece of hardware attached through an SPI controller. In order to get this hardware recognizable in Raspbian, I had to include an additional device tree overlay with my Nerves firmware. Raspbian uses a device tree to manage resource allocation and module loading.[1] In order to make the kernel aware of our external SPI device, a device tree blob (DTB) that describes the hardware must be provided to the kernel on boot. While the process was pretty straight forward for Raspbian, I was left a little lost when it came to translating that over to a Nerves RPI3 system configuration. This was my first Nerves project, and I found the documentation was a little light in this area. (I have since updated the Nerves Advanced Configuration documentation to include information about device tree overlays.)

Customizing Jira for Agile Teams—The Lab Zero Way

Matt Wilson

Software projects take effort to manage; that’s indisputable. In order to ensure that we’re spending our time in the most productive way, we make sure that the tools we use to help manage our projects are lightweight and focused on tracking useful information. Our development team usually prefers Pivotal Tracker and our design team likes Trello. No tool is perfect, but these two seem to have the right balance of flexibility and ease-of use while providing visibility into a team’s progress toward a goal. 

Announcing Bootleg: Simple deployment and server automation for Elixir.

Principal Engineer

At ElixirConf 2017 we began getting the word out about Bootleg, a project we've been working on for most of this year in-between our normal Lab Zero client work. So what is Bootleg exactly?
