Today, we are excited to announce our newest addition in our open-source family, Inspec Delta! In this blog post, we will explain how this is utilized at Cerner to reduce the time in comparing updated infrastructure security benchmarks. Whether you are new to automating your security compliance or have had to deal with maintaining updates to existing benchmarks, this blog post is for you! Background As security standards continuously evolve, the Defense Information Systems Agency (DISA) releases a new revision to their STIG (Security Technical Implementation Guide) for each Operating System major version, as well as certain applications.

Since 2017, we at Cerner have been building Terra, a single page web application framework, and accessibility has always been a primary goal. Over the years we’ve learned a lot about how to build and test accessible websites, as well as the diverse group of people we’re serving. With this blog post, we’d like to take a moment to share what we’ve learned so far. Why accessibility matters At Cerner, we build software for many different users in many different roles.

Back in 2013, like most other companies, Cerner was heavily invested in building user interfaces with Twitter Bootstrap. Around that time, Dave Rupert wrote about the concept of Responsive Deliverables and touched on a key concept, creating “Tiny Bootstraps, for Every Client”.

Common tools include a JavaScript console, JavaScript debugger, DOM explorer, network request viewer, performance profile, local storage manager, and more.

We are pleased to announce Carbon Graphs as an open source code project! Carbon is a lightweight, vanilla JavaScript visualization API built with D3 that integrates well with any consumer’s tech stack. It provides a variety of graph types that are framework agnostic and responsive out of the box. Motivation Over the past few years, we have gradually updated our user interface to use modern JavaScript libraries such as mithril.

We are pleased to announce the release of CCL Unit and CCL Testing as open source code projects, as well as the release of the CCL Testing plugin artifacts to Maven Central. Cerner Command Language (CCL) is a database query and scripting language used with Cerner Millennium databases. CCL Unit is a unit testing framework for CCL written in CCL. The CCL Testing plugins generate reports for viewing the results of CCL Unit tests and static analyses of CCL programs and for generating code documentation from comments in the source code for CCL programs.

Introducing Jwala, a Resource Manager for the Apache Community Apache Tomcat and Apache httpd are hardened, scalable, and reliable open-source solutions. Widely adopted, these solutions are commonly used to host and load-balance Java applications. Configuring and managing a small set of elements is relatively easy, but once you start scaling out your application and platform, things get complicated. Questions such as “How do I update the heap or database pool-size across hundreds of Java Virtual Machines (JVMs)?
